Sildetos creat OLE a Oy Omi The sylvan powers Obey our summons; from their deepest dells The Dryads come, and throw their garlands wild And odorous branches at our feet; the Nymphs That press with nimble step the mountain-thyme And purple heath-flower come not empty-handed, But scatter round ten thousand forms minute Of velvet moss or lichen, torn from rock Or rifted oak or cavern deep: the Naiads too Quit their loved native stream, from whose smooth face They crop the lily, and each sedge and rush That drinks the rippling tide: the frozen poles, Where peril waits the bold adventurer’s tread, The burning sands of Borneo and Cayenne, All, all to us unlock their secret stores And pay their cheerful tribute.

1.—Notice of a new Species of Deer from the Norfolk Forest-Bed. By RANDALL JOHNSON, Esq.
[Plate I.]
Ir is well known that the Forest-bed which runs along the Norfolk coast abounds in mammalian remains of various species. Amongst these the remains of Cervide are largely represented; but they have not until lately received from paleontologists the attention so deservedly due to them. It would not, however, be right to omit to mention the labours of Dr. Falconer, who turned his attention to the Forest-bed fauna during the later years of his life, of the Rev. John Gunn, of Irstead, Norfolk, and, more recently, of Mr. Boyd Dawkins, all of whom have contributed to extend our knowledge on this subject. Among the many remarkable species found in this deposit there is one which is certainly new to Britain, and, so far as I am able to ascertain, one that has not been found in any deposit of corresponding age with the Forest-bed on the continent. This new form is represented by the left antler and a portion of the left frontal bone, which I had the good fortune to obtain myself from the Forest-bed at Hasbro, a Ann. & Mag. N. Hist. Ser. 4. Vol. xiii. 1
2 Mr. R. Johnson on a new Species
small village on the Norfolk coast between Cromer and Yar- mouth, after a very low tide, during the month of March last. Mr. Gunn informs me that it is the upper portion of the Forest-bed which is exposed at the above-mentioned place, and consequently we may consider it of later date than that portion found near Cromer.
The species in question belongs to the large subgenus of palmated deer of which Cervus megaceros, the so-called Irish Elk, is a well-known example; and as it is charac- terized by the great breadth of the frontal bone, I propose to name it Cervus latifrons. In addition to this, the chief characteristics which this remarkable form presents are as follows:—the extreme shortness of the pedicle, if a pedicle can really be said to exist at all; the absence of a brow-antler, the beam of the antler being given off from the frontal bone nearly at right angles, with a slight curvature downwards, while at about the distance of twelve inches from the burr palmation commences and a huge tine is given off from the anterior surface of the beam, which curves round so as to form almost a semicircle. This tine, when compared with the size of the beam, will be found to be very largely developed.
If we compare this antler, possessing the above-named cha- racteristics, with that of Cervus megaceros, to which the species in many respects is nearly allied (notably m its palmation and size), we shall find that there are considerable differences. Cervus megaceros always possesses a brow-antler, although sometimes but faintly indicated ; in the new species we have
y] x
seen that it is entirely absent. Again, in Cervus megaceros there is a great curvature of the beam outwards and in a certain degree upwards, whereas in Cervus latifrons the beam is ex- tremely straight and with only the slightest trace of a down- ward curvature. Besides the differences which exist between the antlers of the two species, one would naturally expect to find differences in other portions of the skeleton; and that there are such is shown by the only portion I possess, viz. the left frontal bone before mentioned. In Cervus megaceros, if we look at the anterior part of the frontal bone we immediately notice that it is very narrow and rather con- vex, while in Cervus latifrons it is very broad and nearly flat.
The annexed drawing (PI. I.), one fourth the natural size, will give an approximate idea of the specimen, the measure- ments of which I give together with those of another larger (but more imperfect) specimen of the same species, which is preserved in the Norwich Museum.

Associated in the Forest-bed with Cervus latifrons there are found several other species of Cervide, which it may be interesting to mention. Of these some are peculiar to the Forest-bed, while others are common to the Forest-bed and other deposits of Pleistocene and Pliocene age both in England and on the continent. The following is a list of the species that have as yet been clearly determined :—
Cervus elaphus. Cervus Sedgwickir.
capreolus. latifrons, n. sp. —— megaceros. Carnutorum. —— martialis. —— Polignacus. ——_ verticornis.
Of the nine species enumerated above two only have lived down to our own times, viz. the Stag (Cervus elaphus) and the Roebuck (Cervus capreolus). These two, together with Cervus megaceros, have not been found in strata of Pliocene age, and therefore, as Mr. Boyd Dawkins justly observes (Quart. Journ. Geol. Soe. Nov. 1, 1872, p. 410), “ point rather forwards than backwards in time.” Cervus martialis—a species with sub- compressed ramified antlers, hitherto unmentioned in lists of Forest-bed Cervide, and closely allied to the Reindeer (Cervus tarandus)—leads us to draw the same conclusion, as it has been found in the Postpliocene sands of Riége, near Pezenas (cf. Gervais, ‘ Zoologie et Paléontologie Francaise,’ p. 144). Of the remaining species, Cervus verticornis (rivalling C. megaceros in size and characterized by the downward and out- ward curvature of the brow-antler), Cervus Sedqwickit (a re- markable form with compressed antlers, described by Dr. Falconer, ‘ Paleontographical Memoirs,’ vol. ii. p. 471), and Cervus latifrons have as yet been found only in the Forest- bed. Cervus Carnutorum and C. Polignacus are Pliocene forms, the former having been found in the Phocene deposit of St. Prest, near Chartres, by M. Laugel, and the latter also in a Phocene deposit at Mont Perrier, near Issoire, and figured by Croizet and Joubert.

4 Dr. H. A. Nicholson on the Genus Stromatopora.
The Forest-bed Cervide taken as a whole, although com- posed of a remarkable and peculiar assemblage of forms, show us, as has been pointed out by Mr. Boyd Dawkins in the valuable paper above mentioned, that the Forest-bed itself is rather of Pleistocene than Pliocene age; and as we know that Elephas primigenius, E. antiquus, and Bison priscus, all Pleistocene forms, are numbered amongst its fauna, we are justly entitled to consider that the data are such as warrant the above conclusion.
Il.— On the Affinities of the Genus Stromatopora, with Descrip- tions of two new Species. By H. ALLEYNE NICHOLSON, M.D., D.Sc., M.A., F.R.S.E., Professor of Natural History
in University College, Toronto.
In the ‘ Annals’ for August 1873 I described four species of Stromatopora (one from the Upper Silurian, and three from the Devonian rocks of Canada), all of which exhibited certain re- lationships with the Spongida. As regards two of the species described in the paper alluded to, I have now obtained some further material, by which certain interesting points of struc- ture are brought out, and the reference of these fossils to the Spongida is still more clearly established. I have also to de- scribe for the first time two new and exceedingly interesting species of the genus—one from the Corniferous Limestone (Devonian), and the other from the Niagara Limestone (Upper Silurian). In the first place, however, it may be as well to discuss briefly the systematic position of the genus Stro- matopora.
The genus Stromatopora of De Blainville includes a number of fossils of doubtful affinities, which have the common cha- racter of forming amorphous masses or irregular expansions, composed of delicate calcareous laminz, arranged in successive strata one above the other, and separated from one another by minute vertical props, pillars, or dissepiments. Very often the successive lamine are disposed round an imaginary centre or centres in a concentric manner, giving rise to spherical, hemi- spherical, or irregularly massive forms. In other cases the
mass * is extended so as to form an expanded cup or irregular
* T would suggest that the term “sarcodeme” (Gr. sara, flesh; demos, people) might advantageously be employed to designate the entire or- vanism or colony amongst the compound Foraminifera and the Sponges. Some such term is certainly needed in treating of such problematical organisms as Stromatopora, of which the exact systematic position is doubtful.

sheet, made up, like the preceding, of successively superim- posed laminee.
The main element, therefore, in the structure of Stromato- pora, and the only one about which all observers are tolerably agreed, is a system of parallel calcareous laminz, generally of great tenuity, not in actual contact, but separated from one another by narrow interspaces. The successive lamin are kept apart by a vertical system of calcareous pillars, which divide the interspaces between the laminz into minute, usually quadrangular compartments, and thus render the whole mass more or less minutely vesicular.
So far, the structure of Stromatopora would be compatible with a reference of the genus either to the Foraminifera or the Spongida; but there are unfortunately many differences of opinion as to the further structure of these fossils, and these have led to equally wide differences of opinion as to the aftini- ties and systematic position of the genus.
According to M‘Coy (Pal. Foss. p. 12) the vesicular tissue of Stromatopora is composed of “ minute, curved, calcareous plates,” which he compares to the ccenenchyma of Palwopora and Fistulipora. He also states that the upper surface is oc- casionally marked “ with extremely obscure, distant, quincun- cially arranged, small pits,” which he appears to think may represent the corallites in the above-mentioned or other allied
enera.
Prof. Hall agrees with M‘Coy in referring Stromatopora to the Coelenterata, and in placing it in the neighbourhood of Tubipora (Pal. N. Y. vol. i. p. 135). He considers that the fossils of this genus are composed of ‘¢ minute cylindrical tubes with considerable space between, and that the laminated struc- ture arises from thin layers of calcareous matter, deposited and filling the spaces between, and enclosing the tubes.”
My own investigations of a very extensive series of speci- mens from the Lower and Upper Silurian rocks and from the Devonian Formation have led me to the conclusion that the genus Stromatopora is clearly referable to the Spongida, and that it should be placed amongst the Calcispongiw, a group represented by many and varied forms both in past time and at the present day. The reasons for this belief may be shortly summed up as follows :—
a. The fundamental structure of Stromatopora is by no means inconsistent with the belief that it belongs to the calea- reous sponges. It does not consist of reticulated calcareous spicula, as in the more typical members of the group; but neither does it consist of a vesicular tissue composed of “ minute curved calcareous plates” (M‘Coy), which could be in any way

compared to the vesicular ccenenchyma of many tabulate corals. On the contrary, it consists of successive calcareous layers which may be regarded as composed of an amalgamated system of horizontal spicules, separated by interspaces, and kept apart by a vertical system of delicate calcareous rods, giving rise to a system of more or less quadrangular cells. The horizontal laminz are upon the whole continuous; but they sometimes subdivide and inosculate; and the vertical pillars are decidedly irregular, beimg sometimes inclined at various angles, and not being placed at uniform distances apart even in all portions of a single specimen. Some of the vertical rods appear to pass continuously through several laminee and across the interspaces between them; but the greater number are confined entirely to the interval between two successive lamine, not being continuous or corresponding with those in the interspace immediately above or below. There is no ground, so far as I am aware, for believing that these vertical pillars or rods are perforated, or could possibly be of the nature of tubes inhabited by the separate zooids of a colony; on the contrary, in all the forms which have come under my notice, there is the strongest possible proof that they are solid and imperforate. There is thus nothing in the fundamental tissue or groundwork of Stromatopora, as above described, which would necessarily preclude us from referring the genus to the Spongida; nor can any stress be laid upon Prof. M‘Coy’s argument that these organisms cannot be sponges on account of their possessing a rigid and inflexible skeleton, since similar reasoning would compel us to remove from the Spongida a vast number of forms the zoological position of which is beyond doubt. At the same time, if Stromatopora consisted wholly of the laminated and reticulated tissue above described, and possessed none of those openings which are so characteristic of the Sponges, then indeed the genus might be more properly referred to the Foraminifera, the near allies of the Sponges in some respects, but destitute of the canal-system which is present in the latter.
b. Such openings, however, can be shown to exist in certain forms of Stromatopora; and there is strong reason for believing that they will ultimately be found to be present in all. ‘Thus in S. striatella, D’Orb., and S. concentrica, Goldf., both typical examples of the genus, Prof. M‘Coy long since de- scribed the existence of vermicular tubes opening on the sur- face by small apertures, and passing more or less vertically through the component layers of the mass (Pal. Foss. pp. 14 & 15). There is some ambiguity in the language used by this eminent paleontologist in describing these tubes and their
Dr. H. A. Nicholson on the Genus Stromatopora. i
openings in S. concentrica; and the evidence is not at present sufficient to warrant any positive statement of opinion as to whether they may correspond with the “ pores” or the “ os- cula’’ of an ordinary sponge. It is probable, however, that they should be regarded as representing the “ pores,”’ and that the “ oscula”’ will yet be discovered by a more extended and complete examination. Again, in S. ostiolata, Nich., a species from the Guelph formation ot Canada, the upper surface of the mass exhibits small but regularly arranged openings, which, from their remoteness and general form, can hardly be regarded as other than “oscula”’ (‘ Annals,’ Aug. 1873, pl. iv. fig. 1). In S. tuberculata, Nich., again, I have now discovered a sys- tem of comparatively large and remote openings, which com- municate with canals traversing the organism, and which appear to fulfil beyond all question the function of exhalant apertures. In S. granulata, Nich., no openings are ordinarily to be detected, probably on account of the manner in which specimens are generally preserved; but I have one example showing both small and large openings, which must be con- sidered as being inhalant and exhalant. In S. perforata, Nich., now described for the first time, the entire mass, or “‘ sarcodeme,” is traversed by numerous and close-set canals of considerable size, which open at the surface in rounded apertures generally placed on conical or chimney-like emi- nences. These must represent exhalant canals and apertures. Lastly, in S. Hindet, also now described for the first time, there is a series of small close-set apertures which must repre- sent ‘‘ pores,” and another series of larger, more remote, and more irregularly disposed openings which can only be regarded as oscula. With the exception, however, of the last-named species and of the single specimen of S. granulata above alluded to, I am acquainted with no species of Stromatopora which has hitherto been shown with certainty to possess two sets of openings—one small and inhalant, the other large and exhalant. It must be remembered in this connexion that the difficulties in the way of observation are in this case extremely great, since the condition of mineralization in which these fossils occur is generally such that the cavities of the mass are filled up with foreign material, whilst the reticulated tissue itself is often silicified. Hence it would be easy for such minute surface-apertures as the “ pores” of a sponge to be irrecognizably filled up and obliterated or to escape detection. c. The shape of the various species of Stromatopora is such as would accord perfectly well with the belief that the genus is referable to the Spongida. Some species are in the form of rounded or irregularly hemispheric or conical masses. Others

are somewhat cup-shaped; and others, again, have the form of irregular and extended crusts, apparently attached at one point to some solid body, from which they spread laterally in every direction, or seem to form incrusting sheets.
Upon the whole, I think the evidence is very decidedly in favour of the view that the genus Stromatopora is referable to the Calcispongize. In accordance with this view, I retain in this genus the forms which I have named S. tuberculata, S. gra- nulata, S. perforata, and S. Hindei, since these are undoubted sponges, and would upon any other view of the affinities of Stromatopora require to have a new genus formed for their reception.

Having now obtained a considerable number of additional specimens of this species, I have to add two observations of importance to my original description. In the first place, I have now obtained specimens showing that the under surface of the expansions of S. twberculata is covered by a thin calea- reous basement-layer, which is thrown into very numerous concentrically arranged undulating wrinkles. This surface thus presents somewhat the appearance of the epitheca of a Favosites ; but it is much thinner and rougher, and is pierced by apertures. In the second place, both the upper and the lower surface exhibit at irregular intervals rounded apertures which are placed at distances apart of from two lines to half an inch, and have a diameter of from half a line to two-thirds of a line. These apertures are wanting in some specimens, which, how- ever, are but fragmentary, whilst they can readily be detected in others. They are the openings of canals which penetrate the mass in a more or less vertical direction; and I noticed their occurrence in my original description of the species, though I did not at that time fully recognize their nature. The case was thus stated by me :—‘‘ Many examples exhibit rounded openings or tubes, from half a line to a line in dia- meter, descending at right angles to the mass, and placed at varying intervals. ‘These openings are not elevated above the general surface. They are not constant in their occurrence, though very generally present; and I have not been able to satisfy myself that they are not truly extraneous to the fossil. They may, perhaps, be annelidous in their nature; or they may be due to the fact that the organism has enveloped a colony of Syringopora, which has subsequently been dis-

solved away”? (loc. cit. p. 93). The materials now in my hands, however, are quite sufficient to prove conclusively that

these canals and apertures are truly parts of the fossil. They are mostly to be detected upon the upper surface of the mass ; but in one large specimen, which seems to have grown from a broad base of attachment and then to have spread out laterally in an irregularly cup-shaped form, they are plentifully deve- loped on the lower surface. It can hardly be that they can be any thing else than openings corresponding to the “oscula”’ of sponges. ‘The “pores” I have not yet made out with ab- solute certainty ; but I believe that the surface-tubercles are truly of this nature, some of them showing almost conclusive proofs of having been perforated by minute openings at their apices.
There would thus appear to be every reason for concluding that S. tuberculata is truly a calcareous sponge ; and the chief question remaining is whether it can with propriety be re-

tained in the genus Stromatopora. My own opinion is de- cidedly against forming a new genus for its reception, since it has the essential structure of Stromatopora ; and the difficulty which I experienced at first in detecting the oscula, even in the examination of a large series of specimens, has convinced me that the occurrence of similar openings may well have been overlooked, even in the type species of the genus.

The specimens upon which my original description of. this species (loc. cit. p. 94) was founded were all from the Corni- ferous Limestone ; and I failed to detect in them any traces of apertures which could be regarded as either pores or oscula. Recently, however, I have obtained an example of S. granu- lata from the Hamilton group of the township of Bosanquet, showing both these sets of apertures ; and I have also obtained additional specimens from the Corniferous Limestone showing the under surface and the mode of growth.
The first of the above-mentioned specimens is only a frag- ment; and its greater portion exhibits all the appearances which characterize the Corniferous examples of the species. The upper surface of the fossil exhibits several rounded or conical elevations, one of which is perforated by a large sub- circular aperture leading down into the interior, and evidently of the nature of an osculum. Whether the other elevations were similarly perforated or not does not clearly appear. The pores are only shown over a small portion of the fossil, and have the form of minute close-set perforations in a delicate calcareous membrane or surface-layer. Beneath this layer, and over all parts of the specimen whence it has been denuded, is seen the ordinary granulated surface from which the name of the species was originally derived. There is thus a probability established that all the specimens from the Corniferous Lime- stone which exhibit simply this granulated surface are imper- fect, and that there has been removed from them an exterior and very delicate membrane in which the pores were pierced. The granulated layer which appears to form the surface in so many specimens would seem on this view to have served the purpose of distributing the water received through the external poriferous layer, the granules with which it is studded being more or less confluent, and giving rise to a complicated system of sinuous or vermicular horizontal channels.
The under surface of S. granulata is covered by a thin, con-
Dr. H. A. Nicholson on the Genus Stromatopora. 11
centrically wr:nkled calcareous membrane, precisely similar to the epitheca of a Favosites or Fistulipora. Usually the species forms extensive crusts of no great thickness; but I have one specimen in which the organism is attached by a broad base to a large Heliophyllum, from which it spreads out laterally in all directions as a horizontal expansion, the under surface being covered with a wrinkled “ epitheca,” and having been obviously free.
3. Stromatopora perforata, Nicholson.
Spec. char. Fossil composed of crusts of varying thickness, made up of thin concentrically arranged calcareous lamine, the interspaces between which are rendered vesicular by ver- tically disposed calcareous rods or dissepiments. From four to five laminz with their intervening interspaces occupy the space of one line. Upper surface undulating, and covered with very numerous rounded apertures, which vary in width from two thirds of a line to one line, and are situated at dis- tances apart of a line, more or less. These apertures are usually placed at the summit or on one side of conical emi- nences ; or they are elevated above the general surface, the mar- gin of the opening on one side being in general higher than on the other. ‘These apertures are the orifices of vertical or somewhat oblique canals, which penetrate the vesicular tissue of the fossil, and are lined with a delicate calcareous mem- brane, marked with faint encircling strie. For a certain dis- tance (two or three limes) each canal descends in a straight line, and then is curved so as to become nearly parallel to the lower surface of the mass, at the same time contracting in its diameter (fig. 2,c). Between the oscula, as just described, the surface is covered with a fine miliary granulation, com- posed of minute pustules placed close together and arranged in irregular vermicular or sinuous lines.
Stromatopora perforata is perhaps the most remarkable species of the genus which has been yet described ; and it can- not be doubted that it is a genuine member of the Calcispongiz, though in some respects an abnormal one. In its internal structure it agrees altogether with S. twberculata, S. granulata, and S. mammillata ; and with the two former of these it agrees further in the possession of a series of apertures which cannot be any thing but “oscula.” No “‘ pores,” however, have been detected, unless some of the surface-tubercles should in reality be perforated, which is likely enough.
S. perforata is readily distinguished from S. tuberculata b the much greater number and closer arrangement of the oscula,

and by the finer and more minute character of the surface- granulation. The number and closeness of the oscula also

separate this form from S. granulata, in which the oscula are remote, and often cannot be detected at all, though in other respects the surface-characters of the two are very similar or even identical. The under surface of S. perforata is still un- known; but the fossil forms thinner or thicker crusts, often covering pretty extensive surfaces, the thicker expansions being composed of a succession of crusts superimposed one upon the other.

Fossil forming thin crusts or subhemispheric masses com- posed of successive concentrically disposed strata, each stratum made up of parallel calcareous laminze separated by interspaces, Sometimes the component laminz of each stratum are parallel with the upper and lower surfaces of the stratum or nearly so ; but more commonly they are oblique to these surfaces. The result of this is that the interspaces between the laminz open on the surfaces of each stratum as so many elongated and oblique apertures, which have usually the form of fissure-like sinuous slits, but sometimes present the appearance seen in weathered specimens of Alveotites.

tum are sometimes connected by transverse pillars, but more commonly they are so bent and curved as to inosculate with one another at points closely approximated, thus giving the whole mass a vesicular structure. Well preserved specimens show about eight laminz in the space of one line. The upper surface of the fossil exhibits not only the linear and vermicular openings above spoken of as produced by the interlaminar spaces, but also a series of large rounded or oval openings, which are more or less irregularly disposed, and which are the orifices of so many canals which penetrate the mass verti- cally or obliquely. ‘The size of these oscular apertures varies ; but most of them have a diameter of from a line to a line and a half. They also vary greatly in their number in a given space, some fragments exhibiting many of them placed close together, whilst others only show a few, and these remote. The walls of the canals leading away from these openings are not lined by a continuous calcareous membrane (as in S. per- forata), but are perforated like a sieve by the elongated slits

produced by their intersection with the interlaminar spaces. Lastly, the general surface is undulating, and the oscula are not elevated upon eminences or papillee.
This remarkable species departs in some important respects from the structure of the typical species of Stromatopora; but it presents at the same time such a close resemblance to forms like S. tuberculata that it does not seem necessary to form a new genus for its reception. The chief peculiarity of the pre- sent form depends upon the fact that the component laminze of the mass are not arranged concentrically as regards the entire mass; but the fossil is composed of concentric layers, each of which is composed of parallel or subparallel laminee disposed obliquely to the surfaces of the stratum. Hence the interlaminar spaces, instead of being parallel with the surface of the mass (as in S. tuberculata and S. granulata), open upon the surface in the form of oblique, sinuous, or vermicular open- ings, sometimes rounded or subtriangular, but more commonly linear and having a transverse diameter of about one hundredth of an inch. It can hardly be doubted that these minute open- ings, which cover the greater part of the entire surface, are of the nature of inhalant apertures or “ pores;” and they com- municate to fragments of this fossil very much the aspect of worn and weathered examples of certain forms of Alveolites and Canites. All those portions of the surface which are not occupied by the pores are taken up by very much larger open- ings, which are certainly exhalant apertures or “ oscula.” Very often the lamine are arranged in any given stratum in a subspiral manner round certain points of the mass, and the pores on the surface have a corresponding arrangement.
Upon the whole, little doubt can be entertained as to the propriety of referring this species to the Calcispongie ; and its structure would strongly corroborate the view that the surface-tubercles in S. tuberculata are truly perforated, and are of the nature of pores, though examples of this species as ordinarily preserved do not exhibit this feature clearly. I have named the present species after its discoverer, Mr. George Jennings Hinde, who has kindly furnished me with specimens for examination.

To the Editors of the Annals and Magazine of Natural History.
GENTLEMEN,
As only one species of Parascyllium is noted in Dr. Giinther’s Catalogue, I beg to give you a brief description of a different one, not very uncommon near Melbourne.
Parascyllium nuchalis, M‘Coy.
Spec. char. Body and fins clouded with two shades of chocolate-brown, with a broad blackish-brown nuchal collar extending from the base of the pectorals to halfway between the eye and the first gill-opening, and two or three very con- spicuous large spots of the same dark colour on each of the fins ; the whole of the sides and back covered with white spots, smaller and more crowded on the dark nuchal collar; under- side of throat and abdomen pale whitish brown. Mouth nearer the extremity of the snout than to the eye.
Length 2 feet 9 inches; snout to anterior edge of orbit 1 inch, to base of pectoral 3$ inches, to origin of ventrals 114 inches, to origin of first dorsal 143 inches, of second dorsal 204 inches, of anal 20 inches, to caudal 25 inches; girth 7 inches.
This beautiful species is adult at the above size, and is easily recognized by its brown-clouded body, dark, wide half collar, and conspicuous round white spots.
IV.—On the Genera Tremarctos, Gervais (Nearctos, Gray), and Mlurina, Gervais (Ailurogale, Fitz.). By THeopore Git, M.D., Ph.D.
In the ‘Annals and Magazine of Natural History’ for August 1873 (vol. xi. p. 183) Dr. Gray has differentiated from the genus to which he had formerly referred it (//elarctos) the Ursus ornatus of Frederick Cuvier, giving to that species the new generic name “ Nearctos.” A distinct subgenus had, however, been long previously proposed for that species by Gervais (‘ Hist. Nat. des Mammiféres,’ tome ii. 1855, p. 20), and named by him 7remarctos. The name evidently refers to one of the characters mentioned as peculiar—the supra-
16 Mr. F. Bates on New Genera
condyloid foramen of the humerus, in which it was said to differ from all the other Urside. This group has been adopted as a distinct genus by the author in his ‘Arrangement of the Families of Mammals.’
In reference to the statement that the supracondyloid foramen is absent in all other Urside (“qui manque a tous autres Ursidés’’), it may be well to recall that it is developed in the humerus of a fossil bear preserved in the paleeontological col- lection of the Museum at Paris, and figured by Cuvier and Blainville (see ‘Ostéographie des Mammitéres,’ Ursus, pl. xvii. dese. p. 93); but, as remarked by De Christol and Blainville, that specimen is doubtless exceptional or “ monstrous,”’ it being the only one known among hundreds examined ex- hibiting such a peculiarity. The same bone has been re- ferred to by Dr. John Struthers, in the ‘Lancet’ (1873, vol. 1. pp. 231, 232), in comments upon the hereditary occurrence of a supracondyloid process in Man. Judging by the figure of the humerus of Tremarctos ornatus given by Blainville, the supracondyloid foramen appears, however, to be a normal characteristic of that species ; but it would be desirable that such supposition should be proved or disproved by the examina- tion of other specimens, and my chief object in this communi- cation is the hope that it may elicit such information.
I venture also to add another reference that has been over- looked by Dr. Gray as well as Dr. Fitzinger. In the ‘ Pro- ceedings of the Zoological Society of London’ for 1867, p. 268, Dr. Gray has proposed a genus Viverriceps for several Felide, and among them the Fe/’s planiceps of Vigors and Horsfield ; and in the ‘ Sitzungsberichte der Akademie der Wissenschaften zu Wien’ for 1869 Dr. Fitzinger has based another genus (Ailurogale) on the same species. A subgeneric group had, however, long previously been proposed by Prof. Gervais (op. cit. p. 87, 1855) for that species, designated “ Ailurin ” (Latin, Alurina), and distinguished by the double-rooted false molars of the upper jaw. In my ‘Arrangement of the Families of Mammals’ I have retained both Mlurina and Viverriceps (restricted) as genera.

and Species of Heteromera. 17
collected all the species possible, and have especially endea- voured to obtain as large a series as I could of each species. I propose now to give some remarks on the species described by me at that time, as well as to describe others that are new.
Hypaulax marginata and sinuaticollis, mihi, 1. c. p. 261.
These two species appear to be very rare, as I have been able to add but one other example of marginata, and not one of sinuaticollis, to the solitary example of each on which their descriptions were founded. The two species are extremely close to each other, but are, at present, well distinguished by the characters given. By some strange error, I have given the prothorax of sinuwaticollis as longer than wide ; it 1s, as well as the entire insect, relatively much narrower in propor- tion to its length than in marginata; the labium is more narrowly and deeply emarginate in front; the space between the palpi narrower and more convex on the face; the mentum is densely hirsute. In both species the mandibles are strongly notched at the apex; the gular furrow is very strong and close to the base of the submentum; the cheek-furrow is deep and curved, extends nearly to the gular furrow, and termi- nates in a large, subpyriform pit or excavation.
My second example of marginata is from Western Australia. It is considerably smaller than the typical example (length 8 lines) ; the chin is strongly bearded; the two impressions on the prothorax are placed further from the base ; and the 3rd and 4th ventral segments are distinctly sinuate behind : these differ- ences are possibly sexual, although I can see no difference in the form of the anterior tibie ; at any rate they are not of suffi- cient value to warrant me in holding it as a distinct species.
Hypaulax tarda, mihi, !. c. p. 262.
This species also appears to be very rare, as I have been able to add but a second example. It is at once to be distinguished from the two preceding by its strongly transverse prothorax, with the hind angles more acutely produced and more outwardly directed, and by its somewhat “ squat” figure ; the mandibles are notched at the apex; the labium is broadly emarginate in front, the space between the palpi narrow, its face but little con- vex; the gular furrow is broad but less deep than in those pre- ceding ; the cheek-furrow is slightly arched, and does not ter- minate near the gular furrow in an expanded subpyriform excavation; the 4th ventral segment is convex and strongly and somewhat sinuously emarginate behind ; and the sides of the prothorax are more finely margined ; the intervals between the rows of punctures on the elytra are flat, even at the sides and

apex; the 9th row of punctures is joined behind (apically) to the Ist, the 8th to the 7th, the 6th to the 3rd, and the 5th to the 4th; these differences, added to those given in the original description, will readily enable any one to separate the species.
My second example is from Wide Bay: it differs from the typical one only in the head having a rounded depression on the crown, the impressions &c. on the prothorax less strongly marked (almost obsolete), the elytra more convex and con- sequently more abruptly declivous behind, the striz a little
fainter, the punctures larger, and the intervals a little less flat.

Labium broadly emarginate and densely ciliate in front, the space between the palpi wide and scarcely convex on the disk; mandibles strongly notched at apex; mentum strongly transverse, strongly angulate at the sides, front margin notched in the middle, a large round fovea on the disk, and, in six out of the seven examples before me, densely hirsute (in the seventh it is entirely naked) ; gular furrow strong, placed di- stinctly further from the base of the submentum than in the species preceding ; cheek-furrow as in H. tarda, but not exten- ding nearly so close to the gular furrow ; the submentum, and that portion of the gula before the furrow, more convex or bulging than in any of the preceding: head formed as in //. tarda, very minutely and distantly punctulate, the punctures more numerous on the epistoma ; epistomal suture well marked, angulate at the sides ; vertex convex: prothorax opaque, more or less transverse, regularly but not strongly convex, feebly emarginate in front; base bisinuate, and a little wider than the apex, sides more or less strongly and regularly rounded, and more or less distinctly sinuous in front of the hind angles, which are ordinarily subacute and directed backwards (in some examples they are a little outwardly directed) ; median dorsal line very faintly marked ; the entire surface minutely punctu- late (in some examples almost imperceptibly so), and there are ordinarily several more or less distinct oblong impressions at each side of the disk and nearest to the base ; the lateral edges though thickened are not, except sometimes at the hind angles, at all channelled or lined within this thickened edge or margin, and have not the appearance of a recurved plait or fold having a fine groove or channel within, as is the case with all the other species of the genus ; scutellum convex, almost equilaterally triangular, pointed behind : elytra subovate, a little less opaque than the prothorax, distinctly wider at base than base of pro-

A very distinct species, and at once to be distinguished from all the others by the form &c. of the prothorax, especially by the character of its lateral edges, as indicated above.
Hypaulax ampliata, n. sp. Oblong, broad, black, slightly shining. Labium broadly and
sinuously rounded and ciliate in front, the space between the palpi rather wide, its face very convex and longitudinally chan- nelled down the centre; mentum naked, plane, transversely cordiform, with the usual small wing-like expansion on each side the apex at back ; mandibles broadly and squarely trun- cated at apex; gular furrow deep but not wide, very distant from base of submentum ; cheek-furrow very short (almost obsolete), scarcely extending beyond the upper corner of the eye beneath: head and prothorax more or less distinctly but very finely punctulate, most strongly so on the epistoma ; epistomal suture distinct, arched, a little sinuous in the middle: prothorax ample, transverse, subopaque, but little convex, di- stinctly widest in front, apex very feebly emarginate, front angle almost obsolete ; sides strongly rounded anteriorly, then subparallel to behind the middle, thence rapidly contracted to the hind angles, which are small, scarcely prominent, and slightly outwardly directed ; base very broadly lobed in the middle, and extending further backwards than the hind angles ; lateral edges strongly thickened, except in front of the hind angles, abruptly interrupted or notched immediately behind the middle; scutellum convex, strongly transversely triangular : elytra a little shining, broadly oval, moderately convex, di- stinetly wider at base than base of prothorax; base strongly emarginate ; basal ridge very thick and prominent, and clearly continuous with the sutural interval, the ordinary short scutellar row of punctures either altogether absent or represented by a
single faint oblong impression; more or less faintly striated ox

Hypaulax orcus, Pascoe (Nyctobates), Journ. Ent. 11. p. 453.
This very variable species is nearly related to the preceding, but may be distinguished by its more oblong parallel form ; the prothorax is less strongly transverse, the apex decidedly arcuate emarginate, the front angles consequently appear more prominent, and are subacute or narrowly rounded; the sides anteriorly are much less strongly rounded, the hind angles longer, more acute, and obliquely outwardly directed, the apex is wider, equal to, or narrower than the base; the head and prothorax are almost smooth; the base of the elytra less di- stinctly wider than the base of the prothorax; the striz more distinct, the intervals, especially at the sides and apex, convex ; the legs are stouter ; the gular furrow situated a little nearer to the base of the submentum ; the flanks of the prothorax strongly wrinkled on the middle; the middle carina of the prosternal process much narrower, the two sulci are consequently much wider and are continued in front (at right angles) halfway across the sternum, in front of the cox, the prosternum thus appearing to have a strong transverse impression before the coxe ; this

Var. acutangulata.
Two examples from New South Wales slightly differ in being a little smaller (10 lines), in having a distinct longitu- dinal impression on the cheek, starting from the lower corner of the eye beneath ; the striz on the elytra stronger than ordi- nary, the intervals more convex and, at the sides and apex, subnodulose. In one of the examples the prothorax is strongly transverse, and the lateral thickened margin is abruptly ex- panded (just below the ordinary notch behind the middle) into a broad rounded tooth, and the hind angles are very acute.
Note. The mandibles in H. orcus and H. ampliata have the apex broadly and squarely truncated; in all the other species the apex is more or less strongly notched or bifid.
Hypaulax tenuistriata, n. sp. Oblong, robust, black, shining. Labium deeply and widely
emarginate in front, with a tuft of hairs at apex of central portion (between the palpi) ; mandibles strongly notched at apex; gular furrow strong, very near to the base of submentum, a short longitudinal groove extending from base of submentum to the gular furrow; cheek-furrow broadly and deeply im- pressed, extending obliquely from the upper edge of the eye beneath to close to the gular furrow: mentum more or less transversely subcordiform, more or less densely clothed with hairs (sometimes very sparsely so); the hairs shorter, finer, and less intermingled than in any of the preceding that have hirsute mentums: head and prothorax minutely (the former very sparsely) punctulate ; crown sometimes impressed by an irregular transverse line and by two small fovez, in others it is a little more convex and smooth; epistomal suture well marked, angulate at the sides: prothorax transverse, convex, feebly emarginate at apex, and always narrower than at base ; anterior angles not prominent; sides more or less strongly rounded to behind the middle, thence contracted in a curve to the hind angles, which are moderately prominent and acute and directed backwards ; base subsinuously truncated ; sides finely margined or thickened, more or less crenulated, and sometimes notched or interrupted at the middle, a little reflexed, distinctly (though not broadly) channelled within the thickened

At once to be distinguished from all the preceding by the finely punctured strie of its elytra and its more glossy black surface. Like all the other species of which a series of examples has been obtained, the form of the prothorax (especially) and of the elytra is subject to considerable variation.
Hypaulax oblonga and H. ovalis, mihi, l. c. p. 263.
A careful examination of a series of nearly forty examples has convinced me that the specimens (one of oblonga and two of ovalis) on which I founded these two species are really the extreme forms of but one species. As the form ovalis has been figured (/. c. plate xi. fig. 1) it will be most convenient to take that name for the species: therefore oblonga = ovalis.
This species is intensely variable in the form &c. of the prothorax *, especially in the amount of rounding of the sides anteriorly. ‘The elytra also are variable as to form; they may be subparallel (as in the form oblonga) or decidedly oval ; and there exists every variety of form between.
This species may be at once distinguished from all the others by the deeply crenate-striate elytra and convex intervals, and by the labium, which has a deep rounded excision at each side in front, the middle portion between the palpi being prominent and rounded in front, and ordinarily without a tuft of hairs.
* It was in error that I described the prothorax of oblonga as longer than wide.

‘From H. tenuistriata, with which it is most closely allied, it may be separated by the above characters, and also by its more slender form, the gular furrow placed less close to the submentum, the absence of the short longitudinal groove from base of submentum, the cheek-furrow shorter and more or less recurved round the lower (narrow) edge of the eye beneath.
Out of the whole of the examples of both sexes I possess of this species but one has the mentum clothed with hairs; this, coupled with what we have seen before in the other species, makes it quite evident that the bearded chin possesses neither specific nor even sexual value.
Hypaulax gayndahensis and H. opacicollis, MacLeay, Trans. Ent. Soc. N. S. Wales, 11. pp. 284 & 285.
As the descriptions of these two species extend to but little over two lines for each, I find it impossible to decide whether they belong to any of my species or not. In a difficult genus like the present, the species of which are subject to great indi- vidual variation, it is impossible intelligibly to characterize the species in such short descriptions.
ASTATHMETUS, n. g.
Mentum slightly pedunculate, winged ; the central portion large, prominent, not wider than long, hexagonal. Mazille with the inner lobe unarmed ; last joint of the palpi elongate- triangulate, the outer side longest. Labium strongly transverse, partly concealed by the mentum, broadly emarginate and ciliate in front; palpi distant, the last joint oval, with the apex broadly truncated. Gula strongly transversely sulcate. Submentum small, transversely triangular, a deep longitudinal sulcus extending from its base to the gular furrow. Cheeks beneath strongly sulcate, the furrow extending obliquely from the base of the antenna, skirting the upper edge of the eye, to close to the gular furrow. Mandibles broadly truncated, and slightly notched near the lower edge at apex. Head sub- prominent, subquadrate ; front a little depressed; front and epistoma together trapeziform : antennary orbits well rounded. Epistoma squarely truncated in front ; the suture well marked at each side. Labrum transverse, front angles well rounded, fore margin ciliate and slightly emarginate.

Prothorax subquadrate, wider than long, but little convex ; apex slightly sinuously emarginate; front angles not prominent; sides very moderately rounded, a little incurved before the hind angles, which are small, subacute, and out- wardly directed; lateral edges a little sinuous, unequally thickened, and channelled within ; base feebly bisinuate, rather thickly margined. Scutellum rather large, curvilinearly tri- angular. lytra elongate-oval, widest behind the middle, and somewhat attenuate at apex, moderately convex, gradually declivous behind ; base emarginate, scarcely wider than base of prothorax, without trace of a thickened margin; shoulders a little oblique: epipleural fold entire (though narrow and becoming vertical) behind. Metasternum short: intercoxal process wide, rounded at apex: prosternal process broad, strongly tricarinate, the middle carina enclosed by the two outer; end broadly truncated. Mesosternum subhorizontal, broadly concave in front, deeply and obliquely impressed at each side above. Legs rather slender: tibia a little thickened outwardly, obsoletely spurred: tars? tomentose beneath ; first joint of the posterior of nearly equal length to the last.
This is the third known genus of the Calometopides, having at the same time both cheek- and throat-furrows. From the other two (Hypaulax and Chileone) this may at once be distinguished by the elongate-ovate and less convex form, the square prothorax, and the total absence of a thickened margin to the base of the elytra.

On the Geographical Relations of the New-Zealand Fauna. 25
VI.—The Geographical Relations of the New-Zealand Fauna. By Captain F. W. Hurron, C.M.Z.S.*
I Know of no part of the world that presents such a promising field to the student of nature as New Zealand. Although small in size, it contains a fauna and flora so peculiar that several naturalists consider it a separate biological province apart from the rest of the world. Isolated from any large con- tinental area longer probably than any other portion of the earth, it contains the remnant of the population of a continent that existed before the Mammalia had overspread the world; and to that has at various times been added, principally from Australia, a colonist population which culminated not many hundreds of years ago in the advent of man. New Zealand, therefore, presents us with what I may call the elements of a continental fauna, or a continental fauna in its simplest state, and consequently in that state which is most advantageous for studying the mutual relations of the animals composing it. Both Mr. Darwin and Mr. Wallace call New Zealand an “oceanic island” from a zoological point of view, owing to the absence of terrestrial mammals and the meagreness of its fauna and flora; that is to say, they consider it an island that has never formed part of a continental area since its last emergence from the sea. But I think that the Struthious birds have certainly as much weight in determining this point as terrestrial mammals, for they have no superior means of dis- persion ; and New Zealand also possesses a frog, which is one of the great characteristics of a continental fauna. From a geological point of view, I do not see how any land, except volcanic and coral islands, could have originated except as part of a large continental upheaval. I think, therefore, that the New-Zealand fauna may be correctly called the remnants of a continental fauna, and that a close study of it will throw great light on many of the most important, but at the same time most obscure, problems in zoology. It will, however, be long before this can be accomplished. The describing and naming of the different animals, which is the foundation upon which all other researches must rest, is as yet far from being com- leted ; the determination of what species are the original in- ficbitacits’ or the descendants of the original inhabitants, of the former continent has hardly been attempted; but all this must be settled before any sound deductions can be drawn as to the reasons of extinction, variation, or permanency of type of the animals.

It is to this latter point that I wish to draw attention—not that I am in possession of information sufficient to prove any one perhaps of the points that I shall raise, but because I think that sufficient is known to establish with great probability the main features in the zoological history of these islands; and this sketch which I now presume to offer will, I hope, in- duce others to examine the subject more in detail, and will give a systematic direction to their observations. I propose to take first the zoological evidence—to point out the principal facts that have to be accounted for and the deductions that they lead to; I will then rapidly glance at the geological and paleontological evidence ; and, finally, I will draw up from the whole the hypothesis that appears best able to account for all the phenomena.
MAMMALIA.
Of our two bats, one (Scotophilus tuberculatus), although not found elsewhere, is closely allied to those of Australia, while the other (Mystacina velutina) forms the only species of a genus peculiar to New Zealand, but related to bats living in South America.
Two species of seal frequent our shores—the sea-leopard (Stenorhynchus leptonyx), which is also found on ice-floes in the antarctic seas, and occasionally extends to Australia, and the fur-seal (Arctocephalus cinereus), which is supposed to occur also on the southern coasts of Australia, and is closel related to, if not identical with, a species found at the Falkland Islands, Cape Horn, South Shetland, and South Georgia. In the Otago Museum there is also a skull that appears to belong to the sea-elephant (Morunga proboscidea). Mr. Purdie in- formed me that it was picked up a long way inland.
Of the Cetacea, some twelve or thirteen species are known, belonging to the six different families into which the marine members of this order have been divided; and it is remarkable that two thirds of them are endemic—that is, not found any- where else. Our two or three species of whalebone-whale have, up to the present, been found nowhere else. The sperm- whale of our northern coasts is probably the same species as that found in Australia and the South Pacific (Catodon aus- tralis) ; it is certainly distinct from the northern sperm-whale (C. macrocephalus), as the lower jaw is much narrower*.
Our ziphioid whales, of which we have three or four species, are all endemic ; and two of them (Berardius Arnuxti and Me-
* A lower jaw of the New-Zealand sperm-whale in the Auckland Museum is 17 ft. 7 in. in length and only 2 ft. 2 in. in width at the con-
dyles ; there are twenty-three teeth on each side, four of which are rudi- mentary only; the length of the largest tooth is 7:4 in.

soplodon Hector?) belong to genera not found elsewhere. None, however, of our Delphiniide are confined to New Zealand. Delphinus nove-zealandie inhabits the antarctic seas and perhaps Tasmania; Lagenorhynchus clanculus is found through- out the Pacific Ocean, but not in Australia; and Orca capen- sts, a lower jaw of which is in the Auckland Museum, ranges from the Cape of Good Hope through the Southern Ocean to Chili, and is also found in the North Pacific and Tas- mania. The blackfish (Globiocephalus macrorhynchus) is found in the South Pacific and Japan, but not in Australia. Our Cetacea, therefore, contrary to what might have been ex- pected, show a nearer relation to the Pacific and Antarctic oceans than they do to Australia; and it is remarkable that no species of porpoise has as yet been described as found in New Zealand, although two inhabit Tasmania.
The absence of terrestrial Mammalia is one of the chief points of interest in New-Zealand zoology, as it proves that there has been no land communication between this country and Australia since the latter was inhabited by Marsupials ; for I consider that the so-called Maori rat and native dog were both introduced by human agency *.
Sir George Grey informs me that he sent to the British Museum some grey “ Maori rats’? which had been caught in the interior of the South Island in 1847 by Mr. Torlesse, and that Dr. Gray had said that they were identical with a rat found in Polynesia, by which he must have meant the black rat (Mus rattus) ; for none of the islands in the Pacific possesses an indigenous rat. Dr. Buller also collected a con- siderable amount of evidence to show that the ‘‘ kiore-maori”’ was identical with a rat (now in the Colonial Museum) which he described (Trans. N.-Z. Inst. ii. p. 1) under the name of Mus nove-zealandie, but which is certainly Mus rattus. Mr. Colenso says (Proc. R. Soc. of Van Diemen’s Land, 1851, p- 301), in a letter to R. Gunn, Esq., dated 4th September, 1850, that after considerable trouble he had procured two specimens of the native rat, which he describes as “ smaller than our English black rat (JZ. rattus), and not unlike it.” Against this we have the statement of Dr. Dieffenbach, who says (‘New Zealand,’ ii. p. 185) that it was the English and not the Norway rat that killed off the “ kiore-maori.”’ This, I think, must be a mistake, as all the Maoris attri-
* Captain Cook remarks, in his first voyage, that rats were “so scarce that many of us never saw them” (Hawkesworth’s ‘Coll. of Voy.’ iii. p- 34). He makes no mention of their ever being used for food ; and I am not aware of any remains of rate having been as yet found in Maori cooking- places.
28 Captain F. W. Hutton on the Geographical
bute the destruction of the edible rat to the brown rat, and it could only have been from Maoris that Dr. Dieffenbach got his information. Mr. Murray also states (Distr. of Mam- mals, p. 277) that the Norway rat (M. decumanus) was not introduced into New Zealand in 1843; but he gives no evi- dence of the truth of this statement; and it is unquestionably erroneous *. The whole of the reliable evidence that we have, therefore, goes to prove that the Maori rat was no other than M. rattus.
The so-called “native dog’ has been determined by Dr. Gray to be Canis familiaris (Proc. Zool. Soc. 1868, p. 508), and not the Australian species or variety called Canis dingo, which is the strongest possible evidence of its beg merely an escaped domestic breed; indeed I am not aware that any na- turalist believes in an indigenous native dog, except Dr. Haast, who has argued (Trans. N. Z. Inst. iv. p. 88) that a wild dog existed in New Zealand before the domesticated one, because in certain old Maori cooking-places he has found remains of the dog but no gnawed bones; while in others, which he considers of later date, he finds gnawed bones t. But I am not aware that he has any proof of the existence of a dog in New Zealand before the arrival of man ; the difference of date of these cooking-places for which Dr. Haast contends is denied by many observers, and his argument derived from the presence or absence of ground stone implements has, I think, been successfully controverted. I can therefore attach no weight to the absence of gnawed bones. On the other hand, there is the fact that no indigenous dog or rat has ever been found on an island that was not inhabited by other Mam- malia; and when we remember that Marsupials came into ex- istence long before rats and dogs, it is difficult to see how the latter conld possibly get to any country without the former coming also. It is evident that neither Banks, nor Solander, nor the Forsters considered the dog and rat that they found in
* Since reading this paper Mr. Nichol has informed me that the brown rat was common in Nelson when he first arrived in the early part of 1842, and that he never saw any other kind there except a single specimen of a very large and slightly striped variety.
+ The skulls of dogs found in old Maori cooking-places prove un- doubtedly that Canis familiaris existed in New Zealand long balers Euro- peans came here. Captain Cook says (21st October, 1769) that the dogs were “small and ugly ;” and Mr. Anderson (‘Cook’s Third Voyage,’ i. p. 153) calls it a “sort of fox-dog.” Captain Cook also says in his first voyage that the dog was used for no other purpose than toeat. The fact that the inhabitants of the Friendly Islands have the same name (kwri) for the dog as the New-Zealanders is strong evidence that the latter brought it with them ; for if not, they would have lost the name, as they have done that of the fowl.
Relations of the New-Zealand Fauna. 29
New Zealand a new species, or they would certainly have mentioned it; neither did Lesson in 1827, nor Quoy and Gaimard in 1831. Dr. Dieffenbach in 1842 was the first to state that a frugivorous rat, distinct from I. rattus, existed in New Zealand, he probably not being aware that J. rattus is entirely frugivorous. I am therefore of opinion that both the rat and the dog were brought by human agency; and it is worth remarking that the Maori traditions relate that they brought both with them (Travers, Trans. N. Z. Inst. iv. p- 58). The specimen of Mus Gouldiin the Auckland Museum (see Trans. N. Z. Inst. ii. p. 3) was caught, I believe, at the Thames in January 1853; and as a mission-station had been established there some years previously, this specimen was no doubt brought over from Australia in their vessel.
The animal seen at Dusky Bay by some of Captain Cook’s sailors (Second Voyage, i. p. 98) was probably a dog, as none on board had at that time seen a dog in New Zealand.
The evidence of a kind of otter inhabiting the South Island rests upon some footprints seen by Dr. Haast, and mentioned by him in his first presidential address to the Canterbury Phi- losophical Society (Nat. Hist. Rev. 1864, p. 30). In the same address he also mentions having seen tracks in great numbers of a small jumping mammal in the river-bed of the Hopkins; but as no further evidence of the existence of these creatures has been adduced, although eight or nine years have since elapsed, it is impossible for me to take any further notice of them in this paper.
BirpDs.
The first point that claims our attention here is the great development of the Struthious birds. This division can be subdivided into two families—one (Apterygide) containing only the kiwis, and the other (Struthionide) including all other living forms as well as the extinct moas. The kiwis in the structure of the egg-shell have an affinity with the Cari- nate division of birds. Their short legs, and the presence of a hind toe elevated above the level of the others, show an approach to the Gallinaceous order; while their long bill, with its slightly swollen tip, resembles in some measure that of the Scolopacide, which have also the same habit as the kiwi of feeling about on the ground with their bill. Gallinago pusilla, moreover, lives in holes, and only comes out at night (Travers, see Art. xxii.).
Thus the Apterygide have a more generalized structure than the other Struthious birds; they therefore belong to an older type, and cannot with any degree of correctness be said
30 Captain F. W. Hutton on the Geographical
to represent the extinct race of moas. The relations between the second family, or the Struthiones proper, are very compli- cated ; but Dinornis, which alone concerns us here, appears to be intermediate between the rheas of South America and the emus and cassowaries of Australia and the adjacent islands. It approaches the rhea in the structure of its egg-shell, and in having only three pairs of sternal ribs; while the emu, the cassowary, and also the kiwi have four, and the ostrich five pairs. In the structure of its feathers and in the shape of its pelvis and skull the moa approaches the emu. The Stru- thious birds exhibit a type of structure intermediate in many respects between the Carimate birds and the extinct Dimosau- rians; and this leads naturalists to suppose that they are but the remnant of a race that once spread over the whole earth. About twelve species are known outside New Zealand ; while here, besides our four species of Apteryx, Professor Owen has determined fourteen species of Dinornis, three of Aptornis, and one of Cnemiornis, thus making a total of twenty-two species of Struthious birds, belonging to four different genera, living in New Zealand only a few hundred years ago—that is to say, nearly twice as many as are found in all other parts of the world put together.
Probably, however, some of Professor Owen’s species of Dinornis are but the young of others; and it seems to me very doubtful whether Aptornis and Cnemiornis should be regarded as struthious birds at all. Itis evident that these two genera are closely related ; and if the wing-bones placed upon Cremi- ornis calcitrans really belong to the legs of the same bird, we must suppose that the sternum had a keel sufficiently developed to support muscles of a size proportionate to the wings; for although we can understand how the kakapo (Stringops), belong- ing to an order of deeply keeled birds, may have lost, by dis- use of the pectoral muscles, the keel on its sternum, we cannot possibly explain how a struthious bird could have had large wing-bones developed unless it had also sufficiently powerful muscles to use them. J also observe that Aptornis defossor now wears a skull similar to that of the late Dinornis casua- rinus, Which skull Mr. W. K. Parker says undoubtedly belonged originally to a Notornis. But, omitting these two genera and making a due allowance for doubtful species of Dinornis, the great number of species living on so small an island is very remarkable when contrasted with other parts of the world. The continent of Africa, including Arabia, con- tains but one (or, according to some naturalists, two) species of ostrich. South America, from Patagonia to Peru, has but three species of rhea, each inhabiting a separate district.
Relations of the New-Zealand Fauna. 31
Australia possesses two species of emu, one on the eastern and the other on the western side, and one species of cassowary on the northern, while five other species of cassowary inhabit other detached islands, from New Britain and New Guinea to the Molucca Islands. I believe that outside of New Zealand no two species of struthious birds are found living in the same district, while here we have now four species of kiwi, and not long ago had at least half a dozen species of moa as well. How can this be accounted for? The solution is readily found by examining the distribution of the cassowaries. Here we have six species inhabiting six isolated localities. If now this region of the earth were to be elevated, these six species might mingle; and if it were subsequently to sink again, all six species would undoubtedly be driven to the higher lands, and we should have in this supposed island a representation of New Zealand inhabited by six species of Struthious birds.
In order, therefore, to account for the numerous species of Dinornis, we must suppose an ancient continent inhabited by one or two species to sink and the birds to take refuge on the different mountain-ranges left as islands above the water. We must suppose that they remained thus isolated from one another for a sufficiently long period to allow of specific changes being brought about, that then by an elevation of the land they once more mingled together, and that, on subsidence again taking place, New Zealand, as the central mountain-chain, formed a harbour of refuge for them all.
Whether this isolation of species points to some cause as yet unrecognized, by which in the struggle for life no two species of struthious bird can live in close proximity, I will not venture to give an opinion; but it is a fair subject for inquiry, and one on which the careful study of the relative ages of moa-bones might throw considerable light, and enable us perhaps to understand the great mortality that must have taken place amongst the moas when confined to these small islands long before man set his foot here.
The distribution, therefore, of the Struthious birds in the southern hemisphere points to a large antarctic continent stretching from Australia through New Zealand to South America, and perhaps on to South Africa. This continent must have sunk ; and Australia, New Zealand, South America, and South Africa must have remained isolated from one ano- ther long enough to allow of the great differences observable between the birds of each country being brought about. Sub- sequently New Zealand must have formed part of a smaller continent, not connected either with Australia or South Ame- rica, over which the moa roamed. ‘This must have been fol-
32 Captain F. W. Hutton on the Geographical
lowed by a long insular period ending in another continent still disconnected from Australia and South America, which continent again sank and New Zealand assumed somewhat of its present form.
Passing now to the Carinate division of birds, the first thing that strikes us is the fragmentary nature of this- part of our avifauna (if we exclude the Gralle and web-tooted birds), thus strongly contrasting with the Struthious division.
Of the first six orders we possess (excluding the Chatham and Auckland Islands) forty-five species, thirty of which are endemic. ‘These have been referred to thirty-one genera, ten of which are found nowhere else ; and these thirty-one genera belong to twenty families, one of which (Stringopide) is pecu- liar to New Zealand. ‘Two families only, the honey-eaters (Meliphagide) and the starlings (Stwrnide), contain more than two genera. The first shows affinity to Australia; but it must be remarked that out of the four species of this family, belonging to four different genera, one genus only (Zosterops) is found in Australia, and the little bird (the ‘‘ white-eye ’’) that belongs to this genus is known to be quite a recent arrival in this country. The Sturnide, on the other hand, show an affinity with Polynesia; for one species only (Calornis metal- licus) of this family is found in the north of Australia and in New Guinea. It should, however, be noticed that three other species are found in the latter island. In this family also our three species belong to three different genera, two of which (Creadion and Heteralocha) are found nowhere else, while the other (Aplonis) is very characteristic of Polynesia; and Aplonis caledonicus, which is said to have been found in New Zealand, occurs also in Norfolk Island and New Caledonia.
It is remarkable that our two owls should both be peculiar to New Zealand, and that one of them (Sceloglaux albifactes) should belong to a genus not found elsewhere ; for the owls are usually widely spread birds, more so, indeed, than the hawks. Itis also worthy of notice that Strix delicatula, which extends its range over most of the Pacific islands and Australia, should be absent from New Zealand.
Our parrots present several points of interest. The kakapo (Stringops habroptilus) is found nowhere else; the genus Nestor extends only to Norfolk Island, while our perroquets, although belonging to a genus (Platycercus) equally plentiful both in Australia and Polynesia, show a greater affinity to the latter, one species (P. nove-zealandie) ranging not only to Norfolk Island, but also to New Caledonia. It is remarkable that we have no representatives of the cockatoos and grass- perroquets so common in Australia and Tasmania; for our own

climate is quite suitable for them. The absence of Polynesian forms is not so remarkable, as they belong chiefly to more tro- pical genera, and the members of the genus Cor/philus are said to live only on bananas.
That we should have two cuckoos which migrate regularly to other countries each more than a thousand miles distant, is a fact that deserves special attention ; for I know of no parallel case in any other part of the world, the distance across the Mediterranean being less than half that travelled over by our summer visitants. ‘Che phenomenon of a bird at a certain season of the year flying out to sea to an island more than a thousand miles distant is remarkable enough, but is rendered still more so in the case of the little shining cuckoo (Chryso- coccyx lucidus, which is supposed to come from Australia) by there being no apparent necessity for it; for this bird migrates east and west, and not from a warmer to a colder climate, and two other closely allied species which inhabit Australia never leave the country at all. Even in the case of the long-tailed cuckoo (Hudynamis taitiensis), which comes to us from the equable climate of the South-Sea Islands, we cannot suppose that its migrations are caused either by alteration of tempera- ture or by want of food; and the question forces itself upon us, How could this habit have arisen? The only reasonable hypothesis is, I think, that at one time the different lands to and from which these birds fly were connected, or nearly so, that the distance between them gradually increased, and that the habit so common amongst birds of resorting each year to the same place to breed was not lost, but gradually merged into a regular migration. From this point of view, the arrival of the shining cuckoo indicates a connexion with Australia or perhaps New Guinea, while that of the long-tailed cuckoo in- dicates one with Polynesia ; and it must be noticed that, while the latter bird is identical with specimens from Polynesia, the former shows such differences in the colouring of the tail- feathers from the birds inhabiting Australia, that it is consi- dered by many naturalists to be a distinct species. Another remarkable fact that has been quite lately brought to light is that the shining cuckoo of the Chatham Islands is not the same variety as that visiting New Zealand, but is almost, if not quite, identical with an Australian species (C. plagosus). This curious fact proves how strong must be the force of habit ; for these birds in their migration to and from the Chatham Islands must pass over, or at least in sight of, New Zealand ; but instead of stopping after a journey of 1400 miles, they continue on for 450 miles more, until they reach the little island that they have selected as their home.

A more difficult fact to account for is the presence of dif- ferent species of grass-bird (Sphenwacus) in both Australia and New Zealand ; for this bird has such feeble powers of flight that it could not cross a river, and must almost of necessity have travelled by land. It must, however, be noticed that this genus extends through the Indian archipelago into India, and I have not been able yet to compare our grass-birds with those of Australia and the archipelago, so that I am not able to say what amount of difference there 1s between them. The genus Keropia has most affinity with South-American birds, while Graucalus melanops, which is closely related to our G. con- cinnus, is said to extend from Australia into New Guinea.
In the order Gralle, or Waders, we come to birds more widely spread than any others, some indeed being almost cos- mopolitan : but even amongst these the isolated character of our fauna is still marked; for out of twenty-eight species be- longing to seventeen genera eight species and two genera are found nowhere else. ‘The most noticeable feature in this order is the existence of a curious genus of rails (Ocydromus) quite unable to fly. Of this genus we possess four species, one in the North and three in the South Island, while a fifth species is found in Lord-Howe Island, and a sixth in New Caledonia. Notornis, although somewhat like the pukeko (Porphyrio me- lanotus) in the bill, has the feeble wings, thick legs, and short toes of Tribonyx Mortierti of Tasmania and Australia. Of our other rails, two (Rallus pectoralis and Ocydromus tabuensis) are spread over Australia and Polynesia, while another (O. affi- nis), although not found elsewhere, is closely related to a species from Australia (O. palustris). In the godwit (Limosa uropy- gialis) we have another migratory bird that probably comes from Polynesia; but as it is also found in Australia, we cannot feel any certainty about it. New Zealand also displays the peculiarity of bemg the only country in the world inhabited by two species of stilt-plover (Himantopus), one of which (Z. nove-zelandie) is found nowhere else. This is probably owing to the length of time that New Zealand has been isolated, and to its having had during the whole of the period a stilt-plover on it, which gradually changed until it attained that remarkable jet-black plumage which is so different from that of any other species ; while the later colonist from Australia (H. leucocephalus) displays the colour usual to the genus. ‘This view is rendered the more probable by the fact that the young of the black stilt-plover have the same pied plumage that is exhibited by the adults of those species from one of which I suppose it to have been derived.
In the crookbill (Anarhynchus jfrontalis) we have another
Relations of the New-Zealand Fauna. 35
curious anomaly which as yet has received no explanation ; and it must also be noticed that Cape Horn, the Cape of Good Hope, Australia, and New Zealand possess each a_ black oystercatcher (Hematopus) which are considered specifically distinct.
Among the herons the only very remarkable fact is the occurrence of the little bittern (Ardea pusilla), a bird found only in Australia and Natal. Our snipe (Gallinago pusilla) very much resembles in plumage G. Stricklandi trom Tierra del Fuego, but it has a shorter bill.
Among the web-footed birds the first thing that claims our attention is the oceanic family of the petrels (Procellariide), for although by no means peculiar to New Zealand*, the great number of species in the southern oceans in comparison with the small number in the northern is very noticeable. The northern and tropical species have all closely allied forms in the southern hemisphere, while many of the southern petrels (such as Ossifraga, Halodroma, Majaqueus, Pterodroma, Dap- tion, and Prion) have no representatives in the northern seas. This leads to the inference that the northern species have been derived from stray southern birds, and that the southern hemi- sphere has been the centre from which most oceanic birds have spread, while land birds, on the contrary, have spread chiefly from northern areas; and this leads to the further inference that the southern hemisphere has been for many ages more oceanic in character than the northern. The next most re- markable point is the great development of the cormorants, New Zealand possessing nine species, four of which are found nowhere else. No other country in the world possesses so many; and the phenomenon can only, I think, be accounted for in the same way as the numerous species of moa—that is, by the former existence of several small islands which have since been elevated to form the present New Zealand. The wide dispersion, however, of two of our cormorants is rather against this view, one (Graculus carunculatus) being found at the Crozet Islands and at Cape Horn, and the other (G. carbo) in Australia, China, and Europe. I| must, however, remark that the identity of the first has not yet been perfectly established, and that the second, although very closely re- sembling specimens from Europe, shows at the same time some difference. Jt may also be useful to remark here that our gannet (Dysporus serrator), although a far better-flying bird than the cormorants, is not found at the Chatham Islands ; and Dr. Finsch informs me that it is undoubtedly different from
* Procellaria Parkinson is peculiar to New Zealand. OX el

the species (D. capensis) that occurs at the Cape of Good Hope. The occurrence of G. brevirostris and G. melanoleucus in New Zealand presents a parallel case to the two species of stilt-plover, with, however, this difference—that, judging from the colours of the young bird, it is probable that G. melano- leucus has been derived from G. brevirostr’s owing to its having been isolated in Australia, and that its descendants have migrated back again to New Zealand.
Of the gulls we possess a species (Larus pomare) which is found nowhere else—a peculiarity of which few countries can boast, but which can perhaps be accounted for by the fact that this gull only frequents freshwater lakes and seldom comes down tothe sea. Our other gulls are widely spread ; but it is a most remarkable fact, which at present appears to me to be quite inexplicable, that neither gulls nor cormorants occur in any of the Polynesian islands.
Of ducks we possess nine species, four, or perhaps five, of which are endemic—one, the blue duck (Hymenolemus ma- lacorhynchus), belonging to a curious genus found only in New Zealand, but related to a genus (Malacorhynchus) in Australia. The others are all found in Australia—one (Pterocyanea gib- berifrons) ranging through New Caledonia and the Indian archipelago, and another, the common grey duck (Anas super- ciliosa), spreading over Polynesia as far north as the Sandwich Islands. The most remarkable circumstance connected with our ducks is the presence of a species of Fuligula, a genus found neither in Australia nor Africa, but belonging properly to the northern parts of America, Europe, and Asia, although one species is found in South America. The occurrence, how- ever, of a northern species (/. cristata) in the Pelew Islands points out to us perhaps the route along which the ancestors of our species travelled.
The Chatham Islands possess thirty-two species of birds (omitting the gulls, penguins, and petrels), of which six are found nowhere else. All the others are found in New Zealand, except the shiing cuckoo (C. plagosus), which, as already stated, migrates to and from Australia. No genus, however, is peculiar to these islands, except perhaps a rail (adlus ? modestus) which is evidently incapable of flight, and which will probably have to be placed in a genus by itself. This curious form must not, however, be regarded as a change pro- duced by long isolation, but rather as an old form preserved from destruction by isolation. The most noticeable cir- cumstance in the Chatham-Island fauna is the absence of Raptores, with the exception of an occasional visit from the harrier (Céreus Gould’), which does not, however, appear
=

to inhabit the islands, or at any rate is exceedingly rare there.
The Auckland Islands possess twelve birds, three or four ef which are endemic, the remainder all belonging to New Zealand. ‘The most remarkable facts are the occurrence of a species of merganser (Mergus australis), a genus found only in high northern latitudes, and of a duck (Nesonetta auck- landica) with very short wings, belonging to a genus found nowhere else.
On Norfolk Island we know of twenty-six birds. Of these,
two (Aplonis caledonicus and Platycercus nove-zelandie) are found in New Zealand and New Caledonia, five others are common to New Zealand and Australia, a species of Nestor (NV. productus) used to inhabit Philip Island close by, and the remainder show an affinity to Australia. _ Lord-Howe Island possesses only six land birds, two of which (Charadrius bicinctus and Ocydromus sylvestris) show a connexion with New Zealand, while the rest show an affinity to Australia.
A review of the facts disclosed by a study of the distribution of the Carinate birds shows that, although the affinity is greater with Australia than with any other place, there is yet a decided leaning towards Polynesia; and when we remember that a large portion of Australia lies in the same latitude as New Zealand, while the whole of Polynesia is far away to the north, I think the difference is not so great as might have been expected*. The distribution of the genus Ocydromus proves that land communication must once have existed between New Zealand, Lord-Howe Island, and New Caledonia; but the absence of cockatoos, grass-perroquets, pigeons, night- jars, and finches indicates that this connexion did not extend to Australia. With the exception of Sphenwacus, which has very feeble powers of flight, all our Australian birds could have crossed over a strait of considerable width. The phe- nomena of the perroquets, starlings, and long-tailed cuckoo of Polynesia being associated in New Zealand with the honey- eaters, grass-bird, and gold cuckoo of Australia, indicate that New Zealand was connected with a tract of land intermediate to both, but perhaps not connected with either ; at the same time the absence of the more tropical Polynesian birds is no evidence that this tract of land did not extend into Polynesia ; and in Zosterops lateralis and Dendrocygna Eytoni, both ot which have appeared since Europeans came into the colony,

we have positive evidence that our islands can even now be colonized from Australia by many kinds of birds, although 1400 miles distant. It would also appear that this transter of birds to New Zealand took place sufficiently long ago to allow of changes of generic value having taken place, while the Chatham and Auckland Islands have been isolated from New Zealand for a time sufficient only for changes of specific value. REPTILIA.
The Reptiles of New Zealand are not numerous. We possess about eight species of lizards, four of which belong to widely spread genera of the family Scincide ; but the species are all endemic. Three others belong to the Geckotide, and form a genus (Naultinus) which is found nowhere else. Of these, one (N. pacificus) is said to be found in some of the Pacific islands ; but the other two are peculiar to New Zealand. Our eighth species, the curious tuatara (Sphenodon punctatum), which is now found only on a few rocky islets in the Bay of Plenty and near Tory Channel in Cook’s Strait, is placed by Dr. Giinther in a separate order from all other lizards on account of the affinity that it shows to the crocodiles. ‘This remarkable form has no copulatory organs, and has uncinate processes on its ribs like birds. It has also nearly twice as many abdominal as true ribs, which protect the abdomen when being dragged along the ground, for, as in the crocodile, the hind legs are too weak to support the hinder parts of the body ; Dr. Giinther also suggests that they may use these ribs for loco- motion as snakes do. It is also remarkable that this animal, which lives in holes and only comes out during warm weather, should have the dorsal crest that is so characteristic of tree- lizards.
TI omit all reference to Norbea? ‘solata, supposed to come from White Island in the Bay of Plenty, because its true locality is not sufficiently well established; if, however, another specimen should be obtained, it would be most im- portant evidence in the present discussion.
But one species of lizard is found on the Chatham Islands, which is very variable, but which I consider to belong to the species Mocoa zelandica; it is, however, larger, and shows some slight differences in the shape of its cephalic shields. _
A ringed sea-snake, probably Platurus scutatus of Australia and Polynesia, is sometimes washed alive on to our coasts as far south as the mouth of the river Waikato, but it is not yet ascertained whether it is an inhabitant of our seas. A peculiar variety of Pelamis bicolor, which as yet has not been found in any other locality, has also been taken on our shores.

AMPHIBIANS.
The amphibious animals are worse represented even than the reptiles, one species of frog (Liopelma Hochstetter’) being the only member of the class. his frog has now been found in three distinct localities, all, however, in the province of Auckland: these are, the Cape Colville ranges from Coro- mandel to Puriri, the Huia on the north side of the Manukau harbour, and the mountains behind Opotiki in the Bay of Plenty. It belongs to a genus not found elsewhere; but its nearest ally is Telmatobius peruvianus from Peru, and it should be remembered that the frogs of Australia are also allied to South-American forms. It is evident that the absence of other Batrachians cannot be accounted for by the unsuitability of climate or want of food; for the common green frog of Australia (Litoria aurea), which has been introduced, has spread with great rapidity around both Auckland and Christ- church.
The evidence of the reptiles, therefore, is that New Zealand has had land communication with some of the Pacific islands at a later date than with Australia; for in the first case there is no specific difference between forms found in both places, while in the latter the species are now quite distinct. Our frog proves a connexion with South America at a period so remote that changes have since taken place of generic value.

VII.—On the Development of the Polypes and of their Polypary. By M. H. de Lacaze-Duruters.*
Last summer the Academy requested the Minister of Marine to permit my embarkation on board the ‘Narval,’ which was then occupied in completing the hydrography of the Algerian coasts. My object in undertaking this voyage was to study again the coral banks, the richness of which I had previously ascertained in 1860, 1861, and 1862.
During the voyage I have had the opportunity of collecting observations, the results of which, indicated in short notes, do not seem to have been accepted in France. I have been able to verify afresh the facts which I am now going to publish in detail, and I think that I ought first of all to communicate these results to the Academy.
I refer now to the development of polyparies.

40 M. H. de Lacaze-Duthiers on the Development
Science does not possess any extensive and connected work on the embryogeny of the polyparian polypes. Nearly all authors whose object has been the investigation of the mode of growth of the polypary have taken on the one hand the calices or polyparites which appeared to be youngest, and on the other those which seemed to be most completely developed, and then, by seeking the terms intermediate between these extremes, have endeavoured to deduce, from the gradual passage from the former to the latter, the laws either of the multiplication of parts or of the general mode of growth of the calices.
We do not find zoologists attempting to recognize the first traces of calcareous deposits in the bodies of the polypes while still in the state of embryos, and to follow these first morganic nodules up to the complete formation of the calice or polyparite with all its elements. Ina word, they have almost exclusively studied the isolated skeleton of the animal, or the polypary itself.
Laws, which we find prevailing in science, have been deduced, not from the study of the framework during tts formation in the embryo, but from the observation of the formed polyparites of different dimensions. In other words, zoologists have thought that they could affirm what must have been from what was at the moment of observation.
In a polyparite (that is to say, in one of the calices of the polypary of an Actiniarian of whatever species) it is well known that there are radiating lamine of various sizes. These lamin of the first, second, third, to nth size alternate regularly in a ccertainorder, The totality of those which are homologous or similar constitutes what is called a cycle. Seeing this, the same thought comes naturally to the mind of every observer ; and it may be said that, in everybody’s opinion, the equal lamine forming a cycle are produced at the same period—that they commenced and continued growing simultaneously, which would explain their equality—and, finally, that the lamine of different sizes are also of different ages, and that their extent is in direct proportion to the duration of their growth (that is to say, their age).
It may certainly be affirmed that this idea, which occurs naturally to the mind, has been the starting-point of the numerous laws formulated from the examination of specimens in collections—laws which have furnished the principal foun- dation for the classifications and for the nomenclature of the parts of polyparies, proposed especially by French authors. Certain German naturalists, particularly MM. Schneider and Rotteken on the one hand and C. Semper on the other, taking
of the Polypes and of their Polypary. 41
up different points of view, have endeavoured to demonstrate the invalidity of these laws and the difficulty or impossibility of verifying or applying them which often exists.
One of my wishes when I went to Africa this summer was to find embryos and very young individuals of polyparian polypes, and to revise, with the view of verifying them, the various theories put forward as to the origin and mode of growth of polyparies. I was fortunate enough to obtain both embryos and very young polypes ; and I have now the honour to present the results of my new observations to the Academy.
It is well known that the polype which clothes and produces a polypary presents round its mouth circlets of tentacles or arms of different sizes, that these tentacles have also been grouped in cycles, and that the same series of laws has been applied to their development as to that of the lamine of the polypary. Now, by following the appearance of the tentacles upon the embryo, we cannot verify any of the laws which we find current; and this I proved in a memoir published last year* .
This causes great perturbation of mind when we desire to pass from the study of the soft parts of the animal to the knowledge of the development of its hard parts. In fact, each tentacle corresponds to a chamber in the body of the polype; and at the bottom of each of these chambers there rises one of the calcareous lamine of the polypary. The question therefore arises at once, whether the chamber and the tentacle belonging to it, as also the calcareous septum which occupies it, follow the same or different laws in their formation.
I have been able during my voyage to ascertain the perfect exactitude of the following facts. .
Two questions presented themselves. It was necessary, in the first place, to didnt in what part and what elementary stratum of the organs the deposition of the calcareous particles of the calice commenced, and then what were the laws govern- ing the appearance and multiplication of the parts of the polypary.
It was logically necessary, in order to trace the progress of the development of the calcareous parts, to know in the first place, just as in the case of the bones, where the first particles were deposited.
French authors suppose that it is in the dermis of the body of the polypes that the principal deposit takes place, and there- fore they give the name of Sclerodermi to the group of corals here under consideration; but it must be remarked that it

42 M. H. de Lacaze-Duthiers on the Development
would be useful at starting to give a precise histological defini- tion of the dermis, which has never been done. Now-a-days two layers are distinguished in the body-walls of polypes, an inner and an outer one, called the ectoderm or ectothelium and the endoderm or endothelium. French authors have spoken of these two layers ; but they have subdivided them into numerous secondary layers separated by a plane of muscular fibres. It is therefore outside this muscular layer that the primitive de- position of the part which in their eyes is the most important takes place, namely that which forms the walls of the calice (theca).
Now the embryogeny and histology of the embryo, studied in young living Astroides of all ages, and not in polyparies at some given moment of their existence deprived of their soft parts, show without any possibility of doubt that the first cal- careous nodules occur and appear in the inner layer or endo- thelium, the histological characters of which are absolutely dif- ferent from those of the outer layer, which does not allow us to confound them. |
Thus, as regards the histological origin of the polypary, it is impossible to continue to accept the old opinion, and con- sequently also the denomination Sclerodermi.
With regard to the law governing the mode of appearance of the septa of the polypary, the following appears to us to be no less certain. ‘The primitive calcareous nodules first de- posited, making their appearance in the thickness of the inner layer, clothe the bottom of the cavity of each chamber of the embryo while it is still without tentacles, and unite together to form usually a central band at the bottom of the chamber, this band being simple towards the middle of the body and bifureate towafds the circumference ; so that at one moment we find at the bottom of each chamber a sort of calcareous Y, the branches of which turned outwards may be either very short or very long.
It is to be remarked that at this period there is no trace of any circumvallation or wall (theca), or exterior boundary of the calice.
By following these first deposits we find that they rise more and more beneath the inner layer, and that filling up the fork of the Y they produce projecting simple lamin, one in each chamber of the embryo. These laminz (the origins of the septa) become soldered to foreign bodies underlying the em- bryos, and constitute the first rudiments of the polypary.
Now, there are twelve chambers; there are consequently twelve primitive septa, and, I repeat, no wall. Nevertheless, by the examination only of the polyparies in collections,
of the Polypes and of their Polypary. 43
zoologists have been led to assume that the wall was first developed, and that from it there originated first of all six septa at the same time, that these six primary lamine, retaining the advance given to them by their age, were the largest septa in the adult, and so on for the septa of the second and third to the mth size. From this we have the admission of cycles the age of which was shown by the size of their elements. Nothing of this kind ever occurs in the embryo of Astrotdes or of the Balanophyllie ; and I have numerous examples of very young individuals all having twelve equal septa before possess- ing any wall, and in which the formation of cycle after cycle of six elements is not admissible.
It is no longer possible to admit that the septa originate from the*wall, and to give the latter the preeminence over all other elements of the calice, since the septa are already well formed when there is no trace of a wall.
Thus as regards the first two cycles the laws according to- which the absolute and relative moment of appearance of the septa and their origin as dependent on one of the elements of the calice were supposed to be governed have no foundation (raison @étre) ; and yet it was especially for these two cycles that these laws were accepted and most easily verifiable. With regard to histological origin it does not seem to us to be possible, at least in the embryo and the species investigated, to continue to attribute it to the dermic layer.
We recognize, therefore, at the origin of the polypary, a rule which does not fail with regard to the mode of multipli- cation of the tentacles in the Actiniaria without polyparies ; and it is as follows :—The number of parts in accordance with a certain typical number is first formed ; afterwards, a greater growth being manifested in certain of these formed parts, there results from it a symmetry which nothing could lead us to foresee if the embryo had not been followed from moment to moment.
It is thus that the tentacles of thé Actiniw, which we find sometimes arranged so regularly in successive cycles in ac- cordance with the type 6 (6 of the first, 6 of the second, 12 of the third, 24 of the fourth, and 48 of the fifth magnitude) are far from having been developed 6 at a first period, 6 at a second, 12 at a third, and so on. ‘The number 12 was first produced, passing successively through the inferior numbers 2,4, 6, and8to12. After its production the sizes alternately remained stationary in 6, and increased in 6 others. Then, but only then, was manifested the radiate symmetry with two cycles apparently of different ages, as indicated by the relation (6,+6.,).
44 Mr. IT. Higgin on the Structure of the
It is the same with the septa of the polypary. The number 12 is first of all produced, but with this difference, that the 12 elements all begin to show themselves at the same moment ; and it is only later on that their unequal growth ranges them in two groups which appear to be of different age, whereas they are only of different sizes.
The facts here brought forward appear to us to be of absolute certainty. ‘They have been repeatedly confirmed, sometimes upon polypes taken swimming in the sea in the form of the embryonic sphere without any divisions, and brought up until the complete formation of their polypary, which was aftixed to the walls of the microscopic cells in which they were kept for observation, which enabled us to follow under the microscope a single embryo, of which the origin of the parts and the forma- tion of the framework might thus be watched—and sometimes also upon very young individuals collected on the rocks of the localities inhabited by Astrotdes or Balanophyllic.
VIII.—On the Structure of the Skeleton of Kuplectella asper- gillum. By Tuomas Hicaain, Member of the Liverpool Microscopical Society. (In a Letter to T. J. Moore, Curator of the Free Public Museum, Liverpool.)
[ Plate ITI. }
[Tue specimen referred to in the following paper is one of two examples purchased of Mr. Geale in November 1866. It is 12 inches in length measured along the outer curve, and of a very uniform diameter of 1 inch. The other specimen is somewhat longer and stouter. Both are in a more natural condition than is seen in the examples usually submitted for sale; and both are of a pale brown colour. ‘The smaller spe- cimen is somewhat compressed towards the top, perhaps owing to pressure while drying; and nearly half the lid-like top is torn away, leaving a jagged edge, marring the beauty of the specimen. The lower third of the sponge is rigid, the rest soft and yielding throughout, the rigidity extending some- what higher upon the inner than on the outer side of the curve. It is; as Mr. Higgin supposes, the specimen referred to b Prof. Wyville Thomson in his “ Letters from H.M.S. Chal- lenger,” published in ‘Good Words’ for July 1873, p. 510. On passing through Liverpool to Belfast in December 1868, he paid a hurried visit to the Museum, saw both examples, and I gave him a fragment from the smaller one for use under the microscope. Itis remarkable that all the specimens

of Euplectella dredged by him off Cape St. Vincent should be uniformly im the condition indicated by the soft part of our sponge. His remarks are as follows :—
“Several samples of Huplectella, very closely allied to the Philippine species, if not identical with it, came up in the trawl off Cape St. Vincent, and gave us an opportunity for the first time of seeing this sponge alive. Dr. J. E. Gray writes to the ‘ Annals and Magazine of Natural History’ that specimens have been received of Huplectella aspergillum in spirit, and that in these the glassy framework is entirely raasked by a soft, brown, corky coating of sarcode. Our fresh specimens entirely bear out Dr. Gray’s description. It would be difficult to imagine that the thick, somewhat clumsy brown tube, perforated with irregular openings, contained any ar- rangement of support so delicate and symmetrical.
“Although the forms of all the spicules, down to the most mi- nute and complicated, are identical, the wall of the tube in the European specimens of Huplectella is not coherent as in most of the Philippine examples. The original spicules of the ske- leton remain separate from one another, and do not become soldered together. One would think that this would be at all events a perfect specific distinction; but one or two of the specimens of Huplectella aspergillum, particularly one in the Museum at Liverpool, are in this condition ; and I am not yet prepared to say whether all may not be thus soft at a parti- cular stage of growth.”’
Mr. Higgin is well known in Liverpool for his great success in micro-photography. He has for some months been earnestly engaged in the study of sponges, and has kindly given this museum the benefit of his assistance in working up the tole- rably numerous specimens already got together. It is a great pleasure and satisfaction to announce a new and zealous worker in a department of zoology so little cultivated, and in which there is so much work to be done.—T. J. Moore. |
Huyton, November 15, 1873. My pear Mr. Moore,
The ELuplectella which you have placed in my hands for examination is a very interesting and valuable specimen ; for it reveals the composition of the network of these beautiful sponges, which I believe has not hitherto been exactly known.
Your sponge is rigid only to the extent of a few inches from the base, and is flexible throughout the rest of the tube. The cause of rigidity in Huplectella is the enclosure within a sili- cious coating of the spicules which form the fibres, which coating, for convenience’ sake, has been called vitreous. This
46 Mr. T. Higgin on the Structure of the
vitreous coating being of the same nature as the spicules them- selves, their outlines become lost to sight in it; it is impossible to distinguish them and trace their form and shape. Most, if not all, of the specimens which are brought to this country from the Philippine Islands are of this rigid character; and conse- quently the structure of the network remains undescribed. In your specimen, however, we have part of the network vitrified and part of it unvitrified; and in the unvitrified portion all the spicules are easily traceable and distinguishable, lying in the position they are destined to occupy in the rigid skeleton, ready for the silicious coating to be poured over them.
- This, I understand, is the sponge to which Prof. Wyville Thomson alludes in his letter from the ‘ Challenger,’ which appeared in the number of ‘ Good Words’ for July last, where he speaks of the examples of Huplectella which were brought up in the trawl off Cape St. Vincent, the spicules of which were not soldered together, but were in the same condition throughout as those of a specimen of Huplectella in the Liver- pool Museum. I learn, too, from Mr. H. J. Carter, of Bud- leigh-Salterton, that “ Dr. Semper, of Wiirtzburg, had seen specimens of Huplectella aspergillum without any vitrified fibre, which he had viewed as young specimens in which the whole would have become vitrified if they had remained long enough in their natural place of growth—that, in fact, the flexible or unvitrified is the primary state of this species.”
The groundwork of the square meshes is an arrangement of very large four-rayed spicules, the arms of which lie longitu- dinally and transversely ; and so large are these spicules that they do not require to be measured under the microscope by the 100th or 1000th of an inch, but may be measured with an ordinary pocket-rule; each transverse arm extends over three to four of the square areas, so that from the tip of the one to the right to the tip of the one to the left is three quarters of an inch to an inch, and the longitudinal arms are still longer. I may here remark that these are genuine four-rayed spicules, and that at the central spot there is no appearance of suppressed arms. As the square areas only measure about one eighth of an inch each, it will be evident that the long arms of these spicules must extend towards each other, meet, and lie along- side one another, the tapering end of one extending up to- wards the thickest part of another. Along these interlocking arms are placed long, straight, and very slender spicules, which are spined from the extremities for a considerable distance along the shaft (Pl. III. fig. 7).
The diagonal lines and all the fine filaments are the long ams of four-rayed and six-rayed spicules, only three of

which, however, are usually produced, the other arms being more or less suppressed or abortive; the tips of the arms terminate in a kind of spear-head form which is spined; these arms are all extremely long, and some exceedingly slender, and they are twisted and bent in a variety of ways to suit the pattern of the network.
The open network of the mouth of the tube is composed of similar spicules interwoven together.
The exterior “ ridges or frills” are also built up of spicules of the same form, the arrangement being that two or more long arms or rays lie along the network of the skeleton, whilst another arm, which is a short or dwarf one, stands up perpendicularly to the surface. ‘These short upright arms are so placed as to form the lines of the ridges ; and amongst them are interlaced the long slender rays of other spicules, in some of which all the transverse arms are suppressed. These ridges therefore contain the principle availed of in mechanical engi- neering in the { iron girder.
Interspersed throughout the whole of the network are nume- rous smaller sexradiate spicules, chiefly of slender form; but there are some with short stout arms which are quite smooth ; the arms of the slender ones are all spined at the ends, and one of the longitudinal arms is usually produced to a great length.
The flesh-spicules are the “ rosettes”’ of the two kinds de- scribed and figured by Mr. H. J. Carter in the November Number of ‘Ann. and Mag. of Nat. Hist.’ plate xii. figs. 4 and 11, 1873.
Exteriorly there are bundles of long straight spicules or rods running along the longitudinal lines of the skeleton for some distance from the base, some of which are smooth, and others barbed.
It is a matter of great satisfaction to have met with a specimen of this species of sponge in which the vitrification isin progress: here it is actually so. In the lower part of the network to which the vitreous cement has been applied, it has been deposited in sufficient quantity to render the skeleton rigid, but not in such quantity or so completely as in the usual rigid examples. The examination of a portion, after boiling in nitric acid and subjecting to considerable heat, shows that the silicious coating has been deposited in layers, just as in the case of the spicules, the only difference, apparently, being that as cement it is amorphous, whilst in the spicules it assumes definite forms. ‘The spicules of this species are, as Mr. Carter remarks, imbedded in vitreous material, much in the same manner as in the horny-fibred sponges the spi- cules are imbedded in horny material. In the Chalinze, how-

ever, and sponges of that character, the enclosing material is added as the spicules are projected and placed in position, they being of a form not able to hold together without extraneous aid. But in the beautiful Huplectella we have what does not occur in sponges generally (if, indeed, it occurs at all in any other species)—that a structure is built up after a par- ticular design which, when finished, is not added to, and which with slight variations obtains in all specimens: the wonderful basketwork made up by the interlacing or inter- weaving of the unusually long fine arms or rays of the va- rious spicules is capable of holding together of itself by rea- son of its form; and the cementing material cannot advan- tageously be added until this is all complete ; but when the whole structure has been finished according to the pattern which is constant in the species, the vitreous coating may be applied and the entire skeleton rendered rigid. Perhaps this silicious cement is not added in some localities ; but in the ex- amples from the Philippine Islands the unvitrified state appears to be, as Dr. Semper suggests, the primary state. I am, dear Mr. Moore, Yours very truly, T. HIGain. EXPLANATION OF PLATE III.

IX.—Notes on Pardalina Warwickii, Gray, Felis guigna, Molina, and Felis Geoffroyi, D’ Orbigny. By Dr. J. E. Gray, F.R.S. &e.
Many years ago there was in the Surrey Zoological Gardens an
animal shown as the “Himalaya Cat,” which is figured by
Colonel Hamilton Smith in Jardine’s ‘ Naturalist’s Library,’ but
not very characteristically, under the name of Felis himalayana,
Warwick. When the animal died it was preserved in the
British Museum, and recorded in the ‘ List of Mammalia in
the British Museum,’ published in 1842, under the name of
Leopardus himalayanus. Mr. Blyth, in the “ Species of the
genus Felis” (P. Z. S. 1863, p. 184), puts F. himalayana of
Warwick as a synonym of Felis viverrina, Bennett, and, not
recollecting that Warwick’s cat and the one in the Museum
were the same specimen, he puts in “ not of Gray ;”’ and in a
note he says, “ #. himalayana is perhaps F. celidogaster of
Temminck,” which he gives as a synonym of Felis viverrina,
Bennett. In fact the synonyma are the regular confusion of a
compiler, which is easily to be understood and apologized for
in Mr. Blyth’s case, but should be a caution to compilers.
When this cat was alive it was just the time that we began to receive fine skins of animals from the Himalayas ; and there was an inclination of the dealers to give Himalaya as the habitat of animals of which they did not know whence they came, as animals from that country were interesting and fetched a good price; but numerous collectors and sportsmen who bave searched that country assure me that the cat is not found there, or at least has not occurred to them; and it has been suggested by Mr. Blyth and others that it may be an inhabitant of South America; but I have not seen any speci- mens from there.
In the ‘Proc. Zool. Soc.’ for 1867, on account of the length of the brain-case of the skull, and shortness of the face and convexity of the forehead, I formed for this cat a genus under the name of Pardalina, and gave it the specific name of Warwickii, because the name of himalayanus.might lead to misconception, and figured the skull (P. Z. 8. 1867, p. 267, fig. 4; and Cat. Carniv. p. 15, fig. 4)
D’Orbigny and Gervais, in the ‘ Bull. Soc. Philomat. Paris,’ 1844, p. 40, and in the ‘Voy. Amér. Mérid.’ p. 21, t. xiv. (animal), & t. xiii. fig. 1 (skull), figure a cat from Rio Negro, in the pampas of Buenos Ayres, under the name of Felis Geoffroyt, which they compare to the Ocelot Chati and Margay, and to the Felis guigna of Molina, which I had not thought of comparing with it when I wrote the paper in the ‘ Proceedings,’ not thinking it likely that a cat from India and one from

South America were the same; but Dr. Sclater (P. Z. S. 1870, p- 796) observes :— The so-called Felis Warwickit being now dead, I have been able to examine it more carefully, and find it to belong to a well-known South-American species, Felis Geoffroyt of D’Orbigny and Gervais ;” and this theory is adopted by Mr. Elliot (P. Z. 8S. 1872, p. 203).
The specimen of P. Warwickii and the figure of FP. Geoffroyt bear a general resemblance, but they appear to me very dif- ferent. The specimen in the Museum is much more spotted, and the spots of the back are smaller and more numerous ; the throat, chest, and belly are largely spotted. The throat is said to be whitish in M. d’Orbigny’s description; and the belly of of his figure is not spotted at all; but this might be a variation, though I should not think it probable.
M. Gervais figures the skull of the South-American cat ; and when his figure and the figure of the skull of Pardalina Warwickii are compared, and his figure with the skull itself, though they agree in the length of the brain-case, they differ greatly in the form and outline of the face, and especially in the outline of the lower jaw; so that I have little doubt that they are distinct, though both may belong to the genus Pardalina.
Molina, in his work on Chili, described a species under the name of Felis guigna. MM. dOrbigny and Gervais asked, “Mais qu’est-ce que c’est que le Felis guigna?” Dr. A. Philippi has described and figured this species and its skull in Wiegmann’s ‘Archiv f. Naturg.’ 1873, p. 8, t. 1. (animal), & t. i. figs. 2. & 3 (skull). The figure of the animal nearly agrees with the figure of Kelis Geoffroy?, and differs from the specimen of Pardalina Warwickii in the Museum in the few- ness of the spots on the neck, and in thechestand belly (according to both figure and description) being white and spotless. The skull figured is that of a young animal, and appears to differ only in age from that figured by D’Orbigny and Gervais ; and there can be no doubt that Melis Geoffroyt of D’Orbigny and Gervais is the same as /’, guégna of Molina and Philippi.
Therefore the synonyma of the species will run thus :— Pardalina Warwickit.
Belly closely spotted.

The British Museum has just received from Mendoza, in the Argentine Andes, a small female kitten of this species. The back has very numerous small brownish spots, and the belly is covered all over with many larger black spots like the adult. It is very different from D’Orbigny’s figure of Felis Geoffroy? from the Pampas and Philippi’s Felis guigna, which have a plain white belly.

Mr. Elliot, in ‘Proc. Zool. Soc.’ 1872, states that the typical specimen of Felis pardinoides, Gray (P. Z. S. 1867, p. 400, & Cat. Carniv. B. M. p. 27), is a young specimen of Felis Geoffroy?, which he identified witha young specimen marked Lf, Geoffroyi in the museum at Leyden, observing that “ the general colour of the animal, with its lengthened annulated tail, is precisely that of the typical /. Geoffroy?,” adopting Mr. Sclater’s opinion that “ the Pardalina Warwickii, Gray, is also 1. Geoffroy?,”’ and that “ the synonymy of this species will therefore be somewhat as follows,” in which he makes all these one species.
The specimen of Felis pardinoides here referred to was re- ceived from the Zoological Society’s museum in 1855, marked as having been presented to the Society by Capt. Innes and as coming from India, as recorded in the ‘Proc. Zool. Soe.’ 1867, p. 400, and ‘Catalogue of Carnivora in the British Museum,’ p. 27. I have named the animal Lelis pardinotdes, because the form of the spots with a light centre has a certain resemblance to those of the American ocelots. I will not undertake to vouch for the accuracy of the habitats we receive from the Zoological Society ; the Indian habitat has not been confirmed ; and the species has a very South-American aspect. The specimen has not the slightest resemblance in its general coloration to the specimen of Pardalina Warwickii in the Museum, or to the figure of Lelis Geoffroyi of D’Orbigny’s ‘Voyage.’ I think it will be an astonishment to every one who has the slightest pretension to be a zoologist that they should have been regarded as belonging to the same
species. p 48
52 Dr. J E. Gray on the Smaller
We received from the Zoological Society along with the specimen of Felis pardinoides the skull belonging to it, which is described in the ‘ Proceedings’ and ‘Catalogue.’ This skull has a sloping forehead and a well-developed face, quite different from the skull of Pardalina Warwickit, more like the skull of an ocelot, showing that it has no relation whatever to the genus Pardalina. It is true that it shows the animal is not aged; but the skull is perfectly developed, and is evidently that of a fully grown animal, and therefore does not justify Mr. Elhot’s assertion that the “ typical specimen is not an adult animal.”
It is greatly to be regretted that Mr. Elliot did not take the trouble to compare the two skulls in the Museum before he made such a random assertion as that £. pardinoides is the same as FP’, Geoffroyt.
Pardalina Warwickii and the figure of Felis guigna have an immense number of small, rather unequal-sized, moderately closely placed solid black spots on the upper part of the body ; those near the centre of the back are smaller, but not united into lines: and PB. Warwickit has larger spots on the under- side of the body, which are largest in the central line; these, according to the description and figures, are entirely wanting in Felis guigna. The tails are cylindrical and blunt at the end.
Felis pardinoides, on the contrary, has large-sized spots of a squarish form, with a pale centre, placed in about four series, more or less interrupted or irregular, on each side of the body ; the vertebral line is marked with a narrow con- tinuous line, which is forked, and more or less continued in front between the shoulders, and with a series of spots on each side of it, which are much smaller than those on the sides: of the body ; the tail is rather thick, the hinder half tapering to a point. The spot with the pale centre sometimes shows a likeness to the “rose” (that is to say, the spot formed of a ring of small spots with a pale centre) found in the American cats ; hence the name of pardinoides. ‘There is nothing of this kind to be seen in P. Warwitckiz, where the small spots are all equally separated.

pardichrous of Hodgson, F. wagati of Elliot, &. nipalensis of Vigors and Horsfield, Leopardus Elliott, L. chinensis, L, Reevesti, and Chaus servalinus of Gray as ‘all varieties of one species, which he calls /. bengalensis, Desmarest, and /. minuta, 'Temminck ; and he considers Felis Jerdoni a distinct species. 1 may observe that Leopardus Ellioti, differing trom the other species by its skull (which has a complete orbit), belongs to the genus Viverriceps, and is therefore out of the question.
Mr. Daniel Elliot is of opinion that Felis Jerdoni, Blyth, is only a variety of Felis rubiginosa (P. Z. S. 1871, p. 760). It has not the long head of a Viverriceps, to which £. rudbi- ginosa belongs, and is much more likely to be a variety of L. minuta, which I considered it in the ‘List of Mammalia,’ 1842, p. 43. He also decides that Felis pardinoides, re- ceived from the Zoological Society as coming from India, is the young of /. Geoffroy from the pampas of South America (P. Z. S. 1872, p. 203); but we have the skull of this cat (which Mr. Elliot could not have observed, though it is mentioned in the Catalogue), which shows that it entirely differs from the skull of Pardalina Warwickii, which he considers the same as Felis Geoffroyz, or from D’Orbigny’s figure of the skull which appears to belong to the genus Pardalina.
I will not vouch for the distinctness of all the species I have entered in the ‘Catalogue of Carnivora in the British Museum ;’ for the progress of science, aided by the collection of more specimens and the study of their changes, may prove some of them to be only varieties of others; but they appear, accord- ing to our present knowledge of the specimens and their distribution, to be worthy of being reckoned as distinct
species. The specimens in the Museum may be arranged thus :—
I. Tail cylindrical, shorter than the body, and marked with black spots. The body with subequal spots, sometimes united on the dorsal line.
a. The body with a multitude of small spots—those on the shoulders and outside of the limbs being the largest, those on the middle of the back between the haunches and, especially, between the shoulders being united into four or six narrow lines. China and Siberia.

Hab. Siberia? B.M,
This species is described from a skin in a very bad state in the British Museum, which Mr. Bartlett, from whom we re- ceived it, believed came from Siberia. Mr. Daniel Elliot (P. Z. S. 1871, p. 758), without giving any authority, calls it a species from ‘ North-western Siberia.” The markings of the skin are difficult to make out from its state; but I have no doubt Mr. Wolf studied it very particularly when he made the figure. The figure is very like that of Felis chinensis; but the spots on the back are not so numerous and small, and those on the underside are large and distinct. Otherwise I should have considered it a specimen of that species.
Mr. D. Elliot considers this skin of a cat the same as the one that Radde collected in Amurland, in Lastern Siberia, and figured and described in his ‘ Reisen im Siiden von Ost-Sibirien’ under the name of Felis undata, Desmarest, and F. minuta, Temminck, from Java; and he considers Ff’, chinensis, from China, the same species. Radde’s figure is very unsatisfactory. It would be desirable to receive speci- mens from the Amurland to see if the Chinese and Siberian specimens are the same, or how they differ, and if the same as the skin in the British Museum that Mr. D. Elliot has named and figured.

from Sumatra, Dr. Horsfield calling it Felis sumatrana; and I placed with it another specimen received from Jeude’s col- lection in Holland under the same name. The two specimens agree in having a short scarcely spotted tail, and may be a variety of that species. Mr. Elliot (P. Z. 8S. 1871, p. 760) observes that “ Blyth’s species [F. Jerdon7] is only a dark form of F. rubiginosa,” and says that Mr. Blyth agrees with him !
How any zoologist could believe that the short-tailed short- headed Felis Jerdoni, with distinct spots, could be the same as the long-tailed, long-headed, and striped Felis rubiginosa is a mystery tome. I believe that their skulls would show that they belong to different genera. The long-headed Felis rubi- ginosa has a long, very peculiar skull, with complete orbits, and belongs to the genus Viverriceps, to which Felis Jerdoni shows no relation.

If this species was brought from India by Capt. Innes, as it was stated, and the habitat which we received with the speci- men from the Zoological Society correct, it belongs to this section; but it has much more the appearance of a South- American cat; indeed it has a good deal of resemblance to Felis mitis. At any rate, it is distinct from any other Indian cat; and we must await the determination of its proper geo- graphical distribution until we have received other specimens with their proper habitat. Mr. Elliot has stated that he believes it to be a specimen of Felis Geoffroy? from the Pampas. I have given my opinion on this crude and extraordinary idea in a previous paper in this number of the ‘Annals’ (p. 49), with a description of the peculiarities of this species.
XI.—On the Bladebones of Balena Hectori and Megaptera nove-zelandie. By Dr. J. E. Gray, F.R.S. &e.
I HAVE received from Dr. Hector the drawings, one twelfth of the natural size, of the scapule of two whales, which he col- lected at Tory Channel, New Zealand.
The smaller one (see ficur e, p. 97) is about two feet high and an inch or two wider at the upper edge. The whalers said it was the scapula of a humpback; but this must be a mistake ; for it certainly has nothing to do with the scapula of Megaptera nove-zelandie (the New-Zealand humpback). The scapule of the humpback or fin-whales are always much broader than high; this is the scapula of a true Balena, and has a distinct acromion process, which is bent towards the condyle, as in the scapula of Macleaytus australiensis figured by me from a spe- cimen in the British Museum sent by Dr. Haast from New Zealand (P. Z. S. 1873, p. 140). I should think it was pro- bably a specimen of this species ; but the upper margin is not quite so broad and expanded, and the figure appears to show
Balena Hectori and Megaptera novee-zelandie. 57
a short, thick, conical coracoid process near the glenoid cavity, which would lead to the idea that it is a distinct species not hitherto recorded as occurring in New Zealand. I propose to call it Balena Heetori.
Bladebone of Balena Hectori.
~ Teall this species Balena because I do not know any of the existing genera to which it can be referred, and think that when we know more of the skeleton to which it belongs it will most probably be the type of a new genus of Baleenide.
This bladebone, from its small size, may be that of Neo- balena marginata, the pigmy New-Zealand whale, which was first known from three blades of whalebone, then from its ear- bone, and at last by the discovery of the whole skull; but the rest of the skeleton is still unknown; and the possession of an acromion process to the scapula, which is not found in any other true whale, would agree with the anomalous form of the bones of the head of that whale.
Theother drawing represents a scapula about 24 feet high and 4 feet wide at its upper edge, which the New-Zealand whalers said belonged to the black whale; and Dr. Hector says it agrees with the scapula that Dr. Knox gave to the museum of the New-Zealand Institute just before he died as that of the black whale. It doubtless belonged to the whale which he so called in his papers.
This figure represents the scapula of a species of Megaptera ; for it agrees with it in its broad oblique outline, and in being destitute of any coracoid or acromion process, or any rudiments of them, like the rudimentary acromion process found in the Pescopia Lalandii of the Cape seas. It 1s most probably the scapula of the Megaptera nove-zelandie, Gray (Cat. Seals and Whales, p. 128, fig. 20), which I established on an ear-bone

This bladebone, although it agrees in general form with that of the European species, differs from it in the outline being more oblique, having the front edge of the scapula more erect, and the back edge lower and more directed backwards than in the bladebone of Megaptera longimana of the North Sea and North Atlantic Ocean.

Mammalia, Recent and Extinct. An Elementary Treatise for the use of the Public Schools of New South Wales. By A. W. Scort, M.A. Sydney: Thomas Richards, Government Printer, 1873. 8vo, pp. 141 and xix. Price 2s. 6d.
Tue Preface informs us that ‘“‘ The following pages, briefly descrip- tive of the economy of Seals, Dugongs, and Whales, and of their principal fossil allies, form the second part or Section B of an ‘ Ele- mentary Treatise on the Mammalia,’ designed for the use of the more advanced pupils in the Public Schools of this country under the direction of the Council of Education.
«« Whatever information we possess upon the natural history of the finned mammals, particularly in a popular yet scientific form, has been so scantily and unequally distributed, that in this direction a comparatively new field may be said to be open to the teacher as well as to the youthful inquirer.
“Influenced also by the great commercial value of the Pinnata, I have felt anxiously desirous to direct without further delay the at- tention, and thus possibly secure the sympathy, of readers other than students to the necessity of prompt legislative interference in order to protect the oil- and fur-producing animals of our hemisphere, or at least some of them, against the wanton and unseasonable acts committed by the unrestrained trades—and thus not only to prevent the inevitable extermination of this valuable group, but to utilize their eminently beneficial qualities into a methodical and profitable industry.
“‘ Keeping steadily in view these two objects, whose importance I trust will bear me out in deviating from my original intention in the order of the issue of publication, I have endeavoured :—first, to interest the youthful mind with selections of well authenticated anecdotes of the general habits of these peculiar animals, accom- panied, however, by those drier details of structural characters essen- tially requisite to assist the more advanced and thoughtful student to a better understanding of the generic distinctions, and to aid him as a work of reference or descriptive catalogue, should he be disposed in after-life to prosecute his researches in this difficult and

imperfectly understood branch of zoology; and, secondly, by de- voting as much space as my limits would permit to the considera- tion of the animals whose products are of such commercial value to man, and whose extinction would so seriously affect his interests, and to point out the pressing necessity that exists for devising pro- tection for the fur-seals and the sperm and right whales of the Southern Ocean.”
_ This work is far more than its title and cheap price would lead one to expect. It is a scientific and popular account of all known seals, whales, and dolphins, far more complete than any English or Continental work that I am acquainted with.
The catalogues of the British Museum are the basis of the work, as far as regards the recent species; the observations on the history and habits of the animals are very well compiled; and we look forward to the continuation of the work with great pleasure. I will make two suggestions to the author.
I think it is to be regretted that the author of this work, intended for the use of schools, should have occupied so much space with giving the synonyms of the species, a subject very interesting to scientific zoologists, but of no importance to even advanced pupils. Secondly, it would be much better if the author, who evidently has little practical means of judging for himself, placed more confidence in the descriptions from real specimens.
In his account of the southern fur-seals, for example, which is a subject particularly interesting to the Australians, he has been misled by Mr. Allen’s observations, when describing some seals of the Northern Pacific, into believing that all the southern fur-seals belong to one species, while Mr. Allen admits that at the time he wrote he had not examined a single fur-seal from the southern hemisphere, but thought they were all one species; whereas I have come to a different conclusion, having under my care two stuffed skins, five unstuffed skins, and two skulls of Arctocephalus antarcticus from the Cape of Good Hope, four stuffed skins and four skulls of Arctocephalus nigrescens from the Falkland Islands, a skull of Arctocephalus cinereus from New Zealand, a stuffed specimen and a flat skin of Arctocephalus falklandicus from the Falkland Islands (which Mr. Scott has done me the honour to call A. Grayz), and two stuffed skins and two skulls of Gypsophoca tropicalis from North Australia ; and I believe that if Mr. Allen had had the opportunity of examining these specimens he would have changed his opinion. While the author puts all these seals under two names, he describes as new a “ top-knot seal” from Patagonia under the name of Arcto- cephalus eulophus, from the notes of a sealer!
It is to be observed that not only do the species above mentioned differ in the form of their skulls, and in general size, proportion of parts, and colour, but also the skins from the Falkland Islands, Aus- tralia, and the Cape bear different prices in the market, and are at once known by the furmonger.—J. E. Gray.

Ostéographie des Cétacés, vivants et fossiles. Par MM. van BenzpEn et Paut Gervais. Livraisons9 & 10. Texte & Atlas.
It is with great pleasure that I announce that I have received the ninth and tenth livraisons of this work, which I feared had been stopped by the French and German war ; and I hope that the work will now proceed regularly. The parts contain the completion of the text of the description of the plates of the Mysticetes, and is signed by P. J. van Beneden, and the commencement of the text of the Cétodontes, and the description of the genus Cachalot (Physeter). The plates all belong to the Cétodontes, and are marked as having been prepared under the superintendence of M. P. Gervais. In the previous notice of this work, entitled ‘‘ Observations on the Whales described in the ‘ Ostéographie des Cetacés’ of MM. van Beneden and Gervais,” in the ‘Annals,’ Sept. 1870, vol. vi. p. 193, I gave the history of it, saying that the book was undertaken and published at the cost of my esteemed friend M. van Beneden, and the text written by M. Gervais, which I did on the authority of a conversation with M. Gervais. M. van Beneden, when he called upon me shortly after in London, informed me that the book was published at the expense of the publisher (was in fact a bookseller’s speculation), and the descrip- tion of the plates of the whales was written by him for the publisher. I offered to make the correction in the next number of the ‘ Annals ;’ but he begged me to let it remain as it was; and believing that he might have a private reason for his request, I obeyed his injunction. But very shortly after M. van Beneden’s return to Louvain he pub- lished a statement as if I had never made the offer. He now signs the end of the description of the Mysticetes, or Whalebone- Whales ; and if the part which each author took in the superintendence of the work had been stated in the prospectus, this mistake would not have occurred.—J. E. Gray.

* On the Organization of the Fossil Plants of the Coal-measures. —Part V. Asterophyllites.” By W.C. Witt1amson, F.R.S., Pro- fessor of Natural History in Owens College, Manchester.
On two occasions the author directed attention, in the Pro- ceedings of the Royal Society (vol. xx. pp. 95 & 435), to the structure of some stems which appeared to him to belong to the well-known genus Asterophyllites, briefly pointing out at the same time their apparent relations to a strobilus of which he had pre-

viously published figures and descriptions (Transactions of the Literary and Philosophical Society of Manchester, third series, vol. v. 1871) under the name of Volkmannia Dawsoni. In the present memoir he gives a detailed exposition of the various parts of the plant, including the roots, rootlets, stems, branches, leaves, and fruit, in different stages of their development. This is done chiefly in two modifications of the primary type—one from the Lower Coal-measures of Oldham in Lancashire, the other from those of Burntisland. In its youngest state, the Oldham form first appears as a mere twig, having a central fibro-vascular bundle enclosed in a double bark. The vascular bundle consists entirely of vessels which are chiefly, if not wholly, of the reticulated type. When divided transversely, it presents a triangular section, the triangle having long narrow arms and very concave sides. The bark is already differentiated into two layers, and has its exterior deeply indented by three lateral grooves—one opposite to each concave side of the vascular triangle. The outer layer is prosen- chymatous, with vertically elongated cells; the inner one consists of cylindrical parenchyma arranged in radial lines, the cells being also elongated vertically. As the plant grew, successive vascular layers were added exogenously to the exterior of the vascular axis. Each layer consisted of a single linear row of vessels, which were of large size opposite the concavities of the triangle, and small where they approached its several angles. The radial arrangement of those in the several growths was equally regular; they were disposed in single radiating series, new laminz being intercalated peripherally as the stem grew. These radiating laminz were sepa- rated by small medullary rays. Owing to the fact mentioned, that the lamin radiating from the concave sides of the central triangle consisted of much larger vessels than those radiating from its angles, three or four such growths sufficed to convert its concave sides into slightly convex ones, whilst a few more such additions converted the vascular axis into a solid cylindrical rod. At this stage its transverse sections appeared definitely divided into six radiating areas—three of large open vessels radiating from the sides of the primary triangle, and three of small ones proceeding from the sides and extremities of the angles. When these growths have thus given a cylindrical form to the vascular axis, a change takes place in its further development. Concentric growths again begin to form; but in them all the vessels are of almost equally small diameters ; hence the abrupt termination of the three areas of large vessels in the younger growths produces a distinct cir- cular boundary line, marking a special stage in the genesis of the stem. rom this point the additions go on uninterruptedly, the vessels of each radiating lamina or wedge increasing slowly in size from within outwards as the stem advances towards maturity. During these further developments the bark has continued to be separated into two well-defined forms. An inner layer consists of very delicate elongated cells with square ends (prismatic paren- chyma); these are seen in the transverse section arranged in ra-

diating lines proceeding from within outwards. The outer bark consists of narrow, elongated, prosenchymatous cells, having very thick walls; at intervals, corresponding with the spaces between the successive verticils of leaves in the ordinary examples of Astero- phyllites, we find distinct nodes where the bark expands into lenti- cular disks. The vascular axis passes through these nodes without undergoing any visible change, either in the position of its vascular layers or in giving off vessels to the nodes or their appendages. The thin peripheral margin of each node sustains a verticil of the slender leaves of Asterophyllites, of which there are about twenty-six in each verticil. The aspect, dimensions, and arrangements of these leaves correspond exactly with what is seen in the ordinary speci- mens found in the coal-shales. Transverse sections of them exhibit a single thick central midrib, but no traces of vascular tissues have hitherto been found in them.
The laminz of the vascular axis are separated by numerous medullary rays of small size; these rarely exhibit more than four or five cells in any vertical series, and usually but one or two. The exterior of the bark is deeply indented in each internode by three very deep superficial grooves, each one of which occupies the side of the stem corresponding with a concavity of the central triangle of the vascular axis. These grooves, which are sometimes double instead of single, extend from node to node, but do not indent the nodal disks. Owing to the great depth to which these penetrate the bark, they give a very characteristic tripartite aspect to each transverse section of these stems.
The Burntisland type agrees with the Lancashire one in ail its leading features of structure and growth; but its vessels are all barred instead of being reticulated, and the author has not met with such beautiful examples of its nodal disks as he has done in the case of the other form ; neither has he seen its leaves attached. On the other hand, he has found specimens of much larger dia- meter than any that have hitherto been detected im Lancashire, exhibiting in an exquisitely beautiful manner the characteristic peculiarities already referred to. The author has also obtained one section from this locality in which a branch is given off. The vessels of this divergent organ are derived from the central por- tion of one of the segments of small vessels, seen in the trans- verse sections, which proceed from one of the angles of the central triangle.
Having elucidated the details of the aérial stems, the author proceeds to examine such organs of fructification as appear to belong to these plants, commencing with the Volkmannia Dawsont which he described at length in the Transactions of the Philoso- phical Society of Manchester in 1871. This is a verticillate strobilus with a central vascular axis, of which latter transverse sections exhibit a close correspondence with the triangular bundle of Astero- phyllites, being also triangular, with concave sides and truncate angles. But in order to adapt this primary fibrovascular bundle to the requirements of the fruit, each of the truncate angles is

enlarged, so as to make the entire section an almost hexagonal one. This axis is surrounded, as in Asterophyllites, by a double bark—an outer prosenchymatous one, and an inner one of more delicate cellular structure. At each node this bark expands into a lenti- cular disk fringed with stiff narrow bracts, which extend upwards and outwards beyond the sporangia. ‘The latter rest upon the bractiferous disks and the basal portions of the bracts, each verticil being fertile. The sporangia are closely packed in about three concentric circles, and attached by sporangiophores originating from each side of the base of each bract. The sporangia have cellular walls; they are full of large spores, each of which has its sur- face prolonged into a number of very long radiating spines. This fruit the author unhesitatingly identifies with the aérial stems previously described.
He then examines various so-called Volkmannie found in the Lancashire Carboniferous shales, of which the internal structure is not preserved, but which, being found with leaves attached to them, admit of no doubt as to their belonging to Asterophyl- lites. These are regarded as being identical with Volkmannia Dawsoni ; hence the author accepts the latter fruit as giving the internal organization of the ordinary Asterophyllitean strobilus. The fruit (which has been previously described by Binney, Carruthers, and Schimper, under the names of Calamodendron commune, Volkmannia Binneyi, and Calamostachys Binneyana)is then investigated. The above authors had associated it with Calamites; but its internal structure is shown to have nothing mm common with that type. It consists of alternating verticils of barren and fertile appendages. The former are nodal disks bearing protective leaves ; the others are verticils of sporangiophores, usually six in each verticil, and which closely resemble those of the recent Equisetacee ; they project at right angles from the central axis, and expand at their outer extremities into shield-like disks, which sustain a circle of sporangia on the inner surface of each shield. The sporangia consist of a very peculiar modification of spiral cells; they are filled with spores which have been described as provided with elaters, like those of Hqgwisetum; but the author rejects this in- terpretation, regarding the so-called elaters as merely the torn fragments of the ruptured mother cells in which the true spores have been developed. The vascular axis is shown to be solid, and without any cellular elements, being wholly different from that of Calamites, in which the vascular axis is a hollow cylinder con- taining an immensely large cellular and fistular pith. In one fine example of Calamostachys Binneyana the author has found the cen- tral fibro-vascular bundle surrounded by an exogenous ring. This, too, exhibits no resemblance whatever to the corresponding growths of Calamites; on the other hand, it corresponds closely with conditions occurring in some parts of Asterophyllites, to which group the author believes the fruit to be related, notwithstanding the peculiarity of its sporangia and sporangiophores. The au- thor is confirmed in his conclusion that this fruit is not Cala-

mitean by his having already described the structure of a true Calamitean strobilus from an example in which the central axis retains most accurately the arrangement of tissues characteristic of Calamitean stems (Manchester Transactions, 1870). A type of stem to which the author had previously assigned the provi- sional generic name of Amyelon is now shown to be the root or subterranean axis of Asterophyllites, specimens being described in which clusters of rootlets are given off, in irregular order, from various points of the exterior of the branching roots. The latter have no medulla; but in the centres of several of them the author finds the peculiar triangular fibro-vascular bundle so cha- racteristic of Asterophyllites ; and remains of the same trifid origin of the vascular layers may be traced in all, in the peculiar curva- tures assumed by the vascular laminz as they proceed from within outwards. The bark consists of two layers: the inner one is composed of ordinary parenchymatous cells, often of considerable size ; the outer one consists of irregular piles or columns of cells, disposed perpendicularly to the surface of the bark, and with their tangential septa in close contact and in parallel planes. The lateral or radial boundaries of these piles of cells are more strongly defined than the transverse septa. In tangential sections of this outer bark, each of these radially disposed columns of parallel-sided cells appears as a single thick-walled parenchymatous cell, whose aspect, in common with that of its neighbours, is that of ordinary coarse parenchyma. Such sections exhibit no indication of the radial elongation of these cells seen in radial and transverse ones. On reexamining the inner bark, we discover the explanation of these appearances. Many of the larger and more peripheral of the cells of the latter are seen to be undergoing division by the development within their walls of secondary cell-partitions, which are parallel with those of the radially disposed columns. It ap- pears obvious that each of the latter was primarily one of the cells of the inner bark, which has become elongated radially, and at the same time divided into a linear series of compressed cells by the growth of a succession of secondary divisions, all of which were more or less tangential to the periphery of the stem.
The author directs special attention to the genetic activity of this inner bark ; the cells of its inner surface were obviously instru- mental in producing the successive circumferential additions to the primary vascular axis, whilst those of its outer surface increased the diameter of the outer bark in the way just described.
After comparing these plants with living forms, the conclu- sion is arrived at that the nearest parallel to the structure of their stems is to be found in Psilotum triquetrum; whilst their general affinities are regarded by the author as Lycopodiaceous rather than Equisetaceous. The exogenous aspect of their successive vascular growths is, if possible, more conspicuous than in most of the other Carboniferous Cryptogams.
The structure of the stems described is identical with that of those found at Autun by Prof. Renault, and assigned by him to

Sphenophyllum ; thus the close affinity of this genus with Astero- phyllites appears to be finally established. The Calamites verti- cillatus of authors is probably the arborescent stem of one of these plants.
“On a newly discovered extinet Mammal from Patagonia (Homalodotherium Cunninghami).” By Witi1am Henry Flower, F.RS.
The author describes the complete adult dentition of a new genus of mammal, founded on remains discovered by Dr. Robert QO. Cunningham in deposits of uncertain age on the banks of the River Gallegos, South Patagonia. The animal appears to have possessed the complete typical number of teeth, 2. e. twenty-two above and below, arranged in an unbroken series, and of nearly even height, and presenting a remarkable gradual transition in characters, in both jaws, from the first incisor to the last molar. The molars more nearly resemble those of the genus Ihinoceros than of any other known mammal ; and, judging only by the general characters of the teeth, the animal would appear to have been a very generalized type of Perissodactyle Ungulate, allied through Hyracodon (a North-American Miocene form) to hinoceros, also more remotely to Macrauchenia, and, though still more remotely, to the aberrant Nesodon and Towodon. 'The generic name Homalo- dotherium was suggested for this form by Professor Huxley in his Presidential Address to the Geological Society in 1870.
MISCELLANEOUS. On the Sterile Eggs of Bees. By C. Cavs and C. von Sresoxp.
Tue existence of fecundated queen bees laying sterile eggs was ascertained incontestably some years ago ; but no certain explanation had been given of this abnormal fact. M. von Berlepsch indeed had suggested that cases of this kind must be ascribed to some patholo- gical state of the female; but no positive observations had been made on this subject. Some opponents of parthenogenesis, such as still exist in France, thought that the sterile eggs were laid by unfecun- dated queens. The observations of MM. Claus and yon Siebold finally settle the question, and will compel those bee-keepers who will not accept the facts of parthenogenesis to seek other arguments. The first case observed by M. Claus was that of an Italian queen born in the middle of May and beginning to lay in the middle of June. From this period she continued to deposit eggs until the 5th of October ; but none of the eggs gave birth to larve. If this queen had been constructed normally but had not been fecundated in May, she ought at least to have produced males by parthenogenesis. Dissection proved that the oviducts and copulatory orgaus were per- Ann. & Mag. N. Hist. Ser. 4. Vol. xin. a)

fectly normal, and that the seminal receptacle swarmed with sperma- tozoids. On the other hand the ovarian tubes, although scarcely reduced in size and number, showed a degenerescence of their contents. The eggs whose dimensions indicated that they were approaching the moment of deposition were but few; and their vitellus presented here and there the same phenomenon of fatty de- generation that was observed in the rest of the tubes, although the deposition of the membrane of the oyum by the epithelium had not ceased.
The second queen observed by M. Claus had not always produced sterile eggs. Her owner, who had obtained her the preceding summer, had ascertained that she laid fertile eggs. Even in the spring he still obtained results from them, but subsequently he ascertained that her fertility had ceased. M. Claus found the re- productive apparatus normal in all its parts, and the seminal receptacle was full of active spermatozoids. The interior of the ovarian tubes presented the same conditions as in the preceding queen, but in a still more distinct fashion. The ova contained in the lower dilatations of the tubes had the vitellus shrivelled into a solid, caseous mass, although the epithelium seemed to have retained its faculty of secreting the shell.
Lastly, M. von Siebold, having received from a Bohemian bee- keeper a queen which only laid sterile eggs, also ascertained that the organs had their ordinary structure, and that the receptacle swarmed with spermatozoids, but that the contents of the ovarian tubes pre- sented an abnormal appearance, Both in the compartment containing vitellus and in the ova themselves, every thing indicated the existence of substances in decomposition, The eggs already enclosed in their shell and ready to be laid were in a very altered state, denoting a dissociation of the elements.
It is therefore an irregularity in the formation of the ovum, and especially of its vitellus, that causes this sterility. It is simply the result of a pathological state, and has nothing to do with partheno- genetic reproduction.
As regards the cause of this degeneration, M. Claus thinks that we must seek it in the influence of bad weather, and in insufficient nourishment. M. von Siebold admits that these circumstances may have a certain injurious effect ; but, according to him, they are not the sole determining causes, since otherwise, as they are of frequent occurrence, queens with sterile eggs would not be so rare as they are in these countries.—Zeitschr. fiir wissenschaft.

I beg to state that I obtained these sponges (as noticed in my letter to Dr. Gray from Singapore) from the reefs in the sea near the village Talisay, on the island of Cebu, Philippine Islands, in March 1872, on the same spot as the other new sponges obtained by me there and described by Dr. Gray in ‘ Annals,’ x. p. 110, 1872, viz. Meyerina claviformis, Crateromorpha Meyeri, and Rossella philippinensis,
The sponges from these reefs, in the straits between the island of Cebu, some small islets near it, and the island of Bohol, are best to be got in the months March till August (the most favourable month is May) at full moon, when the current in the straits is very strong. The fishers drive with the current and draw behind them in their little boats long lines with small hooks constructed for the purpose. Therefore a little hole can be seen in nearly all specimens of Huplec- tella aspergillum and others, where the hook has destroyed the sub- stance of the sponge. Some species are only found in great depths, 50 fathoms for instance ; and only a few fishermen are skilful enough for sponge-fishing.

Gigantic Cuttlefishes in Newfoundland,
As the question of the existence of Cephalopoda of large size may still be regarded as to a certain extent open to doubt, the following letter from the Rev. M. Harvey of St. John’s, Newfoundland, to Principal Dawson possesses considerable interest.
St. John’s, Newfoundland, Noy. 12, 1873. My prar Docror,—I take the liberty of bringing under your notice some account of a gigantic cuttlefish which was seen a few days ago in Conception Bay. The circumstances under which it was seen were as follows :—T wo fishermen were out in a small punt, on October 26, off Portugal Cove, Conception Bay, about 9 miles from St. John’s. Observing some object floating on the water at a short distance, they rowed towards it, supposing it to be a large sail or the débris of a wreck. On reaching it, one of the men struck it with his “ gaff,” when immediately it showed signs of life, reared a parrot- like beak, which they declare was “as big as a six-gallon keg,” with which it struck the bottom of the boat violently. It then shot out from about its head two huge livid arms and began to twine them round the boat. One of the men seized a small axe and severed both arms as they lay over the gunwale of the boat, where- upon the fish moved off and ejected an immense quantity of inky fluid, which darkened the water for two or three hundred yards.
The men saw it for a short time afterwards, and observed its tail i os)

in the air, which they declare was 10 feet across. They estimate the body to have been 60 feet in length, 5 feet in diameter, of the same shape and colour as the common squid; and they observed that it moved in the same way as the squid, both backwards and forwards.
One of the arms which they brought ashore was unfortunately destroyed, as they were ignorant of its importance ; but the clergy- man of the village assures me it was 10 inches in diameter and 6 feet in length. The other arm was brought to St. John’s, but not before 6 feet of it were destroyed. Fortunately I heard of it, and took measures to have it preserved. Mr. Murray (of the Geological Sur- vey) and I afterwards examined it carefully, had it photographed, and immersed in alcohol; it is now in our Museum. It measured 19 feet, is of a pale pink colour, entirely cartilaginous, tough and pliant as leather, and very strong. It is but 32 inches in circum- ference, except towards the extremity, where it broadens like an oar to 6 inches in circumference, and then tapers to a pretty fine point. The under surface of the extremity is covered with suckers to the very point. At the extreme end there is a cluster of small suckers, with fine sharp teeth round their edges, and having a membrane stretched across each. Of these there are about seventy. Then come two rows of very large suckers, the movable disk of each 1} inch in diameter, the cartilaginous ring not being denticulated. These are twenty-four in number. After these there is another group of suckers, with denticulated edges (similar to the first), and about fifty in number. Along the under surface about forty more small suckers are distributed at intervals, making in all about 180 suckers on the arm.
The men estimate that they left about 10 feet of the arm attached to the body of the fish, so that its original length must have been 35 feet.
A clergyman here assures me that when he resided at Lamaline, on the southern coast, in the winter of 1870, the bodies of two ceuttles were cast ashore, measuring 40 and 45 feet respectively.
More than once we have had accounts of gigantic cuttles cast ashore in different localities; but not until now have any portions of them been preserved.
By this mail I send you a photograph of the arm, it is one fourth the original in size. You will readily see the suckers at the extre- mity of the arm. ‘The disks of several of the larger ones have been torn off by carelessness on the part of the captors; a few of them, however, are perfect ; and the smaller ones are not injured. I shall send you also, by this mail, three or four of these suckers which I eut off, the smallest being from the very tip of the extremity and not much larger than a pin’s head.
I shall be glad to hear your opinion of this fish at your earliest convenience.
It is a great pity one arm was destroyed ; and it is still more to be regretted that we did not get the head of the monster.
Yours very sincerely, M. Harvey.
70 Miscellaneous.
The ‘ Field’ of the 13th of December contains a notice of the oc- currence described by Mr. Harvey, communicated by Mr. T. G. B. Lloyd, who received his information from Mr. A. Murray, Provin- cial Geological Surveyor of Newfoundland. Mr. Lloyd very justly suggests that the statement of the width of the animal is more likely to be approximately correct than that of its length, which seems to be excessive ; and he is probably right in assuming that the length of the body of the animal was about 25 feet. The photograph sent by Mr. Murray represents one of the long tentacles of a decapod Cephalopod, probably a Calamary. A woodcut taken from it is given by Mr. Lloyd; and by the kindness of the Editor of the ‘Field’ we are enabled to reproduce this figure.

The Number of Classes of Vertebrates, and their Mutual Relations. By Prof. THxopore Git.
The mind, untrained in scientific logic, in its generalizations re- specting the animal kingdom, if we may judge by the vague ideas elicited by inquiry and by the history of science, instinctively asso- ciates its subjects into groups determined by the nature of their habitat ; and hence we have had the vertebrates differentiated into (1) those especially adapted for progression on land (Quadrupeds), (2) those especially fitted for progression through the air (Birds), and (3) those adapted for life in the water (Fishes); while the residue, not readily combinable with either of those classes, are tacitly overlooked, or, as the serpents, annexed as a kind of appendix to the Quadrupeds, because they most resemble certain of those animals—the lizards. It was therefore a great advance when Linneeus established a peculiar class (Mammalia) for the typical viviparous quadrupeds and the whales, and thus for the first time subordinated habitat and adaptation therefor to structure. While at the present day the ancient ideas have almost entirely disappeared from the system of nature so far as regards the terrestrial verte- brates, they are still to a great extent prevalent in the appreciation of the relations of the aquatic ones. For those vertebrates con- founded by most naturalists under the name of Fishes are very dis- similar among themselves, and so much so even that the differences are more marked and radical than those between any of the superior classes of the branch. If, indeed, considerations of differences of structure are to guide us in the appreciation of the relations and sub- ordination of animals, the current classification must be entirely changed, and the subordination of the highest groups, first sug- gested by Hiickel, should be adopted with some modifications, while, as respects the combination of the “higher” or more specialized classes into superior groups, other principles should guide. One of the chief points to be reconsidered is the association of the Batra- chians with Fishes rather than with the true reptiles. Although no

distinction may be possible between the first two when the class of Fishes has the wide range generally allowed, there is no difficulty in their discrimination with the limits here to be assigned to them. We may then group the classes as follows :—
On the one hand is Branchiostoma or Amphiovus, distinguished by the extension of the notochord (which is, of course, persistent) to the anterior end of the vertebral column, the attenuation of the spinal cord forward and its simple structure, the absence of auditory organs, the simple tubular structure of the heart, and the develop- ment of the liver simply as a diverticulum of the intestine.—This type is called by Hiickel the subphylum Leptocardia or Acrania.
On the other hand are all the other vertebrates, which agree in the termination of the notochord behind the pituitary fossa, the en- largement of the spinal cord forward into a brain, the development of auditory organs, the division of the heart into (two to four) chambers, which in part (one or two) specially receive the blood, and in part (one or two) specially distribute it to the body again, and the differentiation of the liver as an independent and highly spe- cialized organ.—This group is named by Hickel the subphylum Pachycardia or Craniota.
The numerous forms belonging to the last “ subphylum ” are also divisible into two great groups.
In one the skull has no cincture girdling the mouth, and conse- quently no lower jaw, there are no pectoral members or scapular girdle, and there is but one nasal sac, which has a median external aperture.—To this section belong the lampreys and hags, the repre- sentatives of the class of Marsipobranchs.
In the other, the skull has a cincture surrounding the mouth, its inferior portion being specialized as a lower jaw; they have (arche- typically at least) a pectoral member and a shoulder-girdle de- veloped; and there are two nasal sacs, each having an olfactory nerve distributed to an external aperture.—These vertebrates are again divisible into three groups or superclasses.
1. In the first (Lyrifera) the shoulder-girdle forms a lyriform or furcula-shaped apparatus, the scapule and their adjuncts of both sides being connected together below along the median line, and an air-bladder (sometimes lung-like) is typically developed (sometimes, however, atrophied) and (1) either connects with the cesophagus by a single duct or (2) is entirely closed. To this superclass belong the classes of Fishes and Elasmobranchiates.
2. In the second (Quadratifera) the shoulder-girdle is repre- sented by the scapule and their appendages, which are limited to the respective sides, a sternum is differentiated, and instead of an air-bladder are two lungs, each with a special canal, which communicate with the pharynx. The lower jaw is compound and is articulated with the skull by the intervention of a special bone— the os quadratum. ‘To this superclass belong the Batrachians, the Reptiles, and the Birds, the last two forming the group Sauropsida.
3. In the third (Malleifera) the shoulder-girdle is represented by composite scapule, limited to the sides or back; a sternum is

developed ; respiration is entirely effected by highly specialized lungs commumicating with a common trachea; and the lower jaw is composed of simple rami, and articulated directly with the skull, the os quadratum of the other vertebrates being converted into one of the auditory ossicles (the malleus). This superclass is represented by a single class—the Mammals.
The more these groups are studied in all their relations, the more natural do they appear.
As to other questions—that is, whether the true Fishes and Selachians are not separate classes, there is much to be said on both sides, and perhaps the arguments in favour of the class value of the Selachians may be even more weighty than those against them. If, indeed, the Birds and Reptiles are differentiated as distinct classes, similar rank can scarcely be consistently withheld from the Fishes and Elasmobranchiates. If I have heretofore hesitated, it is because of Dr. Giinther’s very adverse views.
Without prejudice to the reconsideration of the question as to the systematic value of the group of Selachians or Elasmobranchiates, the classes of vertebrates may then be distributed, in a descending series, as follows :—
Branch VERTEBRATA. A. Subbranch CRANIOTA. Superclass MaLLerrera. I. Class Mammalia. Superclass QuapRATIFERA. (Sauropsida.) II. Class Aves. IIL. Class Reptilia. ( Batrachepsida. ) IV. Class Batrachia. Superelass LyxrrEra. VY. Class Pisces. VI. Class Elasmobranchiata. Superclass Monorruina. VII. Class Marsipobranchia. B. Subbranch ACRANTA. VILI. Class Leptocardia.
The most nearly related pair of classes are those of Birds and Reptiles ; and preeminently the most homogeneous is that of Birds, all the living representatives of which seem to be members of a single order (which may be distinguished by the name Eurhipidura), and at most divisible into two suborders, the Carinate and the Ratitee. Other orders are represented by extinct types, viz. Saururve and (if the vertebre are peculiar to the group) Odontornithes.— Abstract of a communication to the National Academy of Sciences, made Oct. 29, 1873. Communicated by the Author.

The Parasitic Mites of Birds, a Contribution to the Knowledge of the Sarcoptide. By E. Enuers.
The observations of M. Ehlers, which relate to interesting questions of adaptation and heredity, are made upon an Acarian very nearly allied to that described by M. C. Robin under the name of Sarcoptes mutans. It is also a bird-parasite, and was discovered on a speci- - men of Munia maja, in which it produced excrescences at the base of the beak. For this species and M. Robin’s the author establishes the genus Dermatoryctes, Which is particularly characterized by the form of the feet in the two sexes. He calls his species Dermatoryctes Fossor.
The female of D. fossor is much larger than the male, and also very different in form. It is incapable of moving outside the galleries which it inhabits, partly because it is encumbered by the large eges which it carries in its body, and partly because it cannot touch the ground with its feet. These (which are extremely short) present an epimeron, a coxa, and leg formed of three joints, the terminal joint being a sort of quadridentate clasper, probably homo- logous with the two joints which are distinct in D. mutans, and which M. Robin ealls tibia and tarsus.
The males are smaller and much more active, and also less nume- rous, than the females. Their body is contracted in front and behind; their legs are much longer than those of the females, and differently constructed; in particular, they bear long hairs, and each of them has a sucker with a long pedicle on its terminal joint.
M. Ehlers was unable to ascertain whether this Acarian is ovi- parous or viviparous. He supposes that the membrane of the egg becomes much attenuated at the close of the development, and that the embryo is born after having got free from it, or that this membrane is ruptured during the birth.
In the first period of their hfe the young Acarians run easily by means of their three pairs of legs, which are long and very like those of the adult males; each of them bears at its extremity a sucker with a long pedicle, and five hairs, the longest of which exceeds the sucker.
The transformations through which the animal afterwards passes are the results of a certain number of moults, which must be regarded as being more than mere changes of skin. During these moults the mite remains in a state of immobility and rigidity, which seems to indicate that we have to do with a true case of nymphosis, accompanied by new formations analogous to those observed by Weissman in the metamorphoses of insects. Kiichenmeister had previously witnessed phenomena of this kind in Sarcoptes scabiei, and Claparéde has described in detail the manner in which a new deye- lopment takes place in the interior of the old skin in Ataw and Hoplophora. Matters appear to go on in an analogous fashion in the species observed by M. Ehlers, although this naturalist ue unable to ascertain positively that complete histolysis takes place.
Miscellaneous. is
There are remarkable differences between the development of the male and of the female. The male undergoes no profound changes in passing from the larval to the adult state. In these two phases of its existence it presents the same peculiarities of structure. Its structure perfectly resembles that which we observe in the Sarcoptide in general, in which the legs bear long hairs, and some of them, if not all, have also pedunculated suckers. The characteristics of the family which exist in the young persist in the male until the adult State.-
In the females it is otherwise. The changes which take place in the course of development give rise not only to differences which characterize the adult, but also to arrangements which are not met with in other Sarcoptidee.
At the last moult but one the female appears with its eight legs, its genital aperture, and all its other principal characters. It is then only distinguished from the adult by its not yet having ova in its body, and by the dorsal shield only presenting pointed, conical pro- tuberances, instead of the flattened scales which this region exhibits in the adult. After increasing in bulk it undergoes another moult in order to attain its definitive condition, in which the dorsal surface is covered with flattened scales. These protuberances, which are in themselves of but little importance, are interesting because they also appear in the mites of the genus Sarcoptes, in which they are parti- cularly developed in the female sex. In the species of which the adult females do not present these projections, they are also wanting in the male; in Sarcoptes scabiei they are found not only in the adult female, but also, although much less developed, in the male. In Dermatoryctes fossor they are exclusively characteristic of the female. M. Ehlers thinks that this formation of the skin may have been originally a secondary sexual character of the females which has become a little attenuated in the species under consideration, whilst in other female Sarcoptide it has maintained itself and even been transmitted to the males by heredity.
The legs of the females undergo remarkable transformations at the last moult ; they become short stumps which have lost a joint, and no longer possess hairs or suckers. The Sarcoptidse of the Mam- malia present a similar modification, although far less profound; for the females have their last two pairs of legs destitute of suckers, whilst the males possess them at least on the last pair but one. On the other hand, in Dermatophagus and Dermatokoptes (Fiirst.) the female has a sucker at least in one of the posterior pairs of feet, and in the male we find one on each foot; this fact is the more remark- able because in these genera the sucker does not exist in the larval state, and only appears at the last change of skin. The two genera in question differ from the true Sarcoptes in not piercing canals in the epidermis of their host, but living more on the surface, concealed by the hairs, the cells detached from the epidermis, &c. The disap- pearance of the suckers and the shortening of the legs consequently seems, in the Sarcoptes, to be in connexion with the mode of life, and especially with the nature of the habitat ; so that those which
76 Miscellaneous.
require to form galleries undergo the greatest abbreviation of the legs, which must have been influenced especially by the comparative dis- use of those organs.
The female of D. fossor lives at the extremity of a straight gallery, which it completely fills. Under such conditions its short, strong legs are very useful to it in progressing after the fashion of a mole, by pressing obliquely against the walls of the gallery, so as to push the animal forward. Outside the gallery these legs could be of no use to it. The young females and the males, on the contrary, can move in galleries which are as it were too large for them.
The rectilinear direction and the small size of the galleries is ex- plained by the hardness of the horny substance of the beak in which they are pierced, which causes the animals to confine themselves to a straight passage, having exactly the calibre of their bodies. In the Mammalia, the epidermis of which forms a less resistant tissue, the passages are tortuous, increase gradually in depth, and offer more space to the mites than is afforded to the parasite of the bird’s beak. —Zeitschr. fiir wissenschaftl.

Contributions to the Knowledge of the Laboulbenie. By Dr. J. Pryritscx.
The author describes the mode of occurrence and the development of these parasitic fungi. Hitherto only five species of Laboulbenie were known, three of which were observed on beetles. New species have been detected on Carabidae, Staphylinide, and Dytiscide. By their development, and especially the processeof fecundation, the Laboulbenie approach the other Ascomycetes; fecundation takes place by the contact of delicate, filiform organs, pollinodia and trichogyne. The pollinodia are developed at the terminal part of the young plant upon peculiar bearers, the form of which is charac- teristic of the species ; the trichogyne terminates the rudiment of the fruit. In some species the latter is a delicate filament of several joints; but in Laboulbenia musce it is unicellular ; in all species it is thrown off after fecundation. The fruit is only developed after fecundation ; it opens by an apical pore and allows the spores to escape. ‘The spores are produced in diverticula of one (or several ?) cell in a series of cells, the upper extremity of which previously formed the trichogyne. The form and insertion of the bearer of the pollinodia and its appendicular structures, and the form of the armature of the mouth of the fruit, furnish the most important characters for distinguishing the species of this small group of fungi. Dr. Peyritsch’s memoir contains descriptions of all the species, which are referred to five genera,—Anzerger der Akad, der Wiss. in Wien, October 23, 1873.

XII.—Deseriptions of two new Genera and Species of Polyzoa from the Devonian Rocks. By H. ALLEYNE NICHOLSON, M.D., D.Sc., M.A., F.R.S.E., Professor of Natural History in University College, Toronto.
In the following communication I propose to desetibe two new genera of Polyzoa which I have been compelled to found for the reception of two remarkable fossils from the Devonian rocks of Western Ontario. Both of these belong to the family of the Fenestellide; but they differ in an extraordinary manner from all previously recorded genera, and present certain points of structure of a very anomalous nature.
Genus Crypropora (Nicholson).
Polyzoary forming a rigid, infundibuliform, calcareous ex- pansion, springing from a strong solid branching root-stalk or rhizome. Exterior of the ccencecium forming a continnous non-perforated calcareous layer, internal to which is a second or intermediate layer, the two being composed of the amal- gamated and coalescent branches (“interstices”). The inter- mediate layer is marked by shallow and bifurcating longitu- dinal sulci, corresponding with the lines between the branches ; and its surface exhibits reticulating lines which correspond with the bases or proximal ends of the cells beneath ; but no fenestrules are present. The internal surface of the inter- mediate layer carries the cells, which are flask-shaped, and

are arranged in double alternating rows forming regularly flexuous lines enclosing oval interspaces, exactly as in Letepora. The oval interspaces, however, instead of constituting so many “fenestrules,” are the bases of so many pillars, which proceed perpendicularly inwards, across a central space, to jon with an internal calcareous membrane which forms the innermost lining of the funnel-shaped frond.
It follows from the above description that the mouths of the cells in Cryptopora neither open on the exterior of the frond, as is commonly the case in Fenestel/a, nor upon the interior of the frond, as is the case in the infundibuliform species of Retepora. On the contrary, we have im this extra- ordinary genus the unique arrangement that both the internal

and the external aspects of the funnel-shaped polyzoary are to all appearance closed by a continuous calcareous membrane. The cells are not placed upon either of the free surfaces of the polyzoary, but occupy a central space, which has its internal wall formed by the innermost membrane, and its external wall by an intermediate layer composed of the laterally coalescent branches. ‘The cells are situated upon the internal face of the outer wall of this central space; and the two walls are kept apart by a system of pillars, which traverse the central space perpendicularly, and correspond in position with the fenestrules

of a Retepora. It would thus appear that the water must have been admitted to this central space, and thus to the cells, by openings in the free edge or lip of the infundibuliform poly- zoary ; but none of my specimens exhibits this portion of the frond.
In the genus Hemitrypa, Phillips, the fenestrules do not perforate the coencecium so as to reach the outer face of the frond, but are filled by a calcareous membrane. The cells, however, open upon the external surface, instead of into a central space; and the structure of the polyzoary is in other respects very different.
The following is the only species of the genus that I have as yet met with, though additional forms will probably be afterwards detected.
Cryptopora mirabilis (Nicholson).
Polyzoary infundibuliform, apparently from one to three imches in height and three quarters of an inch or more in diameter distally. Hxternal layer thin, imperforate, smooth or obscurely striated. Intermediate layer formed of the coa~ lescent branches, and marked externally by vertical shallow grooves, which are placed about half a line apart and some- times bifurcate. Between these grooves the external surface is mapped out by inosculating lines into small oval or poly- gonal spaces corresponding with the cells. The imternal surface of the intermediate layer carries the cells, which are arranged biserially in flexuous lines, and enclose oval or rhomboidal interspaces. These interspaces are arranged in very regular diagonal lines, about four in the space of two lines ; and they give origin to a series of short rounded pillars, which extend inwards at right angles to meet the internal layer. ‘The central space, in which the cells are situated, is about half a line to two thirds of a line indepth. The internal layer is apparently thi and membranous. ‘The entire frond springs from an exceedingly strong, horizontal, branched stalk, the surface of which is marked by vermicular strie.
The materials in my hands are not sufficient to permit of an entirely satisfactory elucidation of the characters and structure of this remarkable species. Different specimens, however, or different parts of the same specimen, show the following appearances :—
1. The external membrane is thin, and is only preserved in parts of any specimen that I have seen; and as it corre- sponds with the reverse or non-poriferous face of an ordinary Retepora, it is to be regarded in reality as nothing more than
the exterior portion of the intermediate layer. vi 7
80 Dr. H. A. Nicholson on two new Genera and
2. The intermediate layer (together with the external layer, as just remarked) is clearly formed by the coalescent branches. When viewed from the outside, where the thin outer layer has been stripped off, it exhibits shallow vertical grooves, marking out the original branches, and it also shows in outline the proximal ends of the cells below (fig. 1, E, 6).
3. Specimens which exhibit the hollow interior of the funnel, from which the innermost membrane has been removed in whole or in part (fig. 1, D), exhibit the mouths of the cells as rounded pores placed on the inner aspect of the amalgamated branches. The cells are arranged in double alternating rows forming regularly bent or undulated lines, each of which corre- sponds with the inner surface of a branch, and which, by their inosculation, enclose oval spaces corresponding to fenestrules, but occupied by short solid columns.
4, Specimens which are broken across transversely (fig. 1, I’) show that, instead of fenestrules or perforations between the anastomosing branches, we have a series of stout pillars, which run perpendicularly inwards from the poriferous face, and have their internal ends connected together by a thin caleareous membrane, which forms the innermost lining of the funnel- shaped frond. There is thus formed a central space (c), which is lined outwardly by the cells, and to which water can ap- parently not have been admitted otherwise than by openings in the margin of the funnel.
5. Specimens which are casts of the interior of the frond, to which the innermost membrane with the ends of the per- pendicular columns still remain adherent, are not uncommon (fig. 1, A&C). These show that the columns are so arranged as to form beautifully regular diagonal lines ; and their inner ends seem to have been convex, as they in many cases leave concave or cupped scars of an oval or rhomboidal shape upon the outside of the cast (fig. 1, B).
6. One specimen exhibits a strong horizontal ‘footstalk, from which the ccencecium grew up vertically (fig. 1,C). This footstalk is branched at both ends; its surface is covered in parts with vermiculated strie ; and its structure seems to have been minutely tubular or cellular.
7. Lastly, some specimens show the extraordinary character of a second frond, quite similar in structure to the first, in- vaginated within the outer one, so as to give rise to an internal cone closely applied to the external funnel. I am at present, with the comparatively imperfect materials in my possession, unable to offer any explanation of this remarkable feature.

Genus Carrnorora (Nicholson).
Polyzoary infundibuliform, calcareous, and_ reticulated. The external layer of the cyathiform frond is composed of regularly undulated flexuous branches (“ interstices ’’), which anastomose with one another, after the manner of a Letepora, so as to form a series of oval fenestrules. Exteriorly the branches are angulated or carinate, and are smooth and non- celluliferous. Internally each branch gives origin to an enormously developed keel or vertical lamina, which corre- sponds in direction with the branch, and is directed inwards towards the centre of the funnel. The inner surface of the branches thus presents a series of parallel ridges of great height, separated by deep grooves, at the bottom of which, to all appearance, the cells open. The fenestrules also open at the bottom of these grooves. In parts of the frond, however,

these grooves are apparently rendered vesicular by the deve- lopment of a series of delicate calcareous laminz, which connect together the sides of contiguous ridges. In some cases, also, the inner edges of the ridges are connected together by a con~ tinuous calcareous membrane, so that the inner surface of the frond is completely closed. The cells are carried in alternating double rows upon the inner and lateral aspects of each branch, their mouths appearing to be situated at the bottom of the grooves before mentioned and at the base of the great keel which springs from each branch internally. Obviously , how-
82 Dr. i. A. Nicholson on two new Genera and
ever, the row of cells on one side of any branch opens into one groove, whilst the row on the opposite side of the same branch opens into a contiguous groove, and not into the same one. No cells are carried upon the areas formed by the ana- stomosis of contiguous branches.
I have only seen a single, very large and well-preserved example of this genus; and a careful examination of this has still left me unable to elucidate and explain some of the most extraordinary structural peculiarities which it presents. There can, however, be no doubt as to the complete distinctness of the genus from any previously described. A comprehension of the very remarkable characters presented by this genus will perhaps be best obtained from a detailed account of the different figures of the above illustration, all of which represent different portions of the only known specimen :—
a. This figure exhibits a portion of the exterior of the frond, showing the fenestrules and the outer non-celluliferous aspect of the branches. In the portion here illustrated of the natural size, and partially shown at 6 on an enlarged scale, the fenes- trules are oval and arranged in diagonal lines, and the branches are strongly keeled—the general appearance closely resembling the non-celluliferous aspect of Retepora prisca, Goldfuss, and the fenestrules being similarly formed by the simple inoscu- lation of the branches without the development of distinct dis- sepiments.
c. This represents another portion of the exterior of the frond, nearer to the base, where the fenestrules are polygonal or hexagonal and are not arranged in regular diagonal lines. Here also every fourth or fifth branch has a nearly straight direction, giving the network quite a peculiar appearance. In some eases, lastly, the fenestrules present the appearance of being closed by a delicate external membrane.
d. his shows a small portion from which the outer non- celluliferous layer has been denuded, showing the proximal ends or bases of the cells, arranged in a double inosculating row on each branch, and lying in the same plane as the fenestrules.
e. This figure exhibits, on an enlarged scale, a small portion of the exterior of the frond, from which the outer non-celluli- ferous layer has been stripped off together with the cells them-
selves, leaving to view the circular mouths of the cells arranged
in two alternating rows, which are still on the same plane as the fenestrules, and which do not encroach upon the spaces formed by the inosculation of the branches.
f. This figure is a greatly magnified representation of a transverse section of the frond at a point considerably removed

from the base, showing the branches cut across. Above, the branches are separated by the fenestrules; and immediately beneath this are seen the dark oval spaces which represent the cavities of the biserial cells, and two of which are contained within the cavity of each branch. Below this, again, each branch is seen to give off an immense keel or ridge, which is directed inwards towards the interior of the frond. These ridges are separated by deep intervening grooves; and there can be no doubt that the cells open at the bottom of these grooves, those of one side of the branch opening on one side of the base of the great keel, and those of the other opening upon the opposite side of the same.
g. This exhibits a greatly magnified transverse section of the frond at a point a little above the base. As in the pre- ceding, we can recognize without difficulty the shallow fenes- trules, the divided branches carrying in their interior each a pair of cells, and the great internal keels. Here, however, we have two new features: first, the deep grooves between the keels are subdivided by delicate calcareous lamine, which connect the opposite sides of contiguous keels, and divide the intervening grooves into shallow transverse chambers ; secondly, the grooves between the keels are closed internally by a continuous calcareous membrane which has a minutely porous or vesicular structure.
h. This represents a fragment taken from near the base of the funnel and exhibiting the internal surface of the polyzoary. We see here the inner faces of the great longitudinal keels ; but instead of these being separated by deep sulci as in the upper portion of the frond, they are here separated by shallow rounded grooves formed by a continuous calcareous membrane, which is not penetrated by either the fenestrules or the cells. No apertures, therefore, of any kind appear on the interior of the ccencecium near the base, the open interstitial grooves of the upper portion of the frond being here closed by a continuous connecting layer. At the right-hand corner of the figure the keels and their connecting membrane are broken away, so that we see the cavities of the rows of cells; whilst the ex- treme corner is still further broken away, so that the fenestrules come into view.
z. This simply represents a single branch in transverse section, greatly enlarged, and shows the cells in the interior of the branch and the great triangular keel proceeding from its internal surface.
From the above description it will be evident that the structure of Carinopora is quite anomalous, and wholly unlike any thing that has hitherto been observed in any member of
84 On two new Genera and Spectes of Polyzoa.
the Fenestellide. The most anomalous point is the position of the cells, or rather their mode of opening on the surface. The cells open towards the interior of the funnel-shaped frond, as in fetepora, and in the upper portion they seem to open simply at the bottom of the deep intercarinal grooves, into which the fenestrules also open; so that there is here no special difficulty, if, as seems tolerably certain, the keels are not here connected by an imperforate membrane, and the grooves thus remain open to the access of sea-water. Near the base, however, the keels are clearly connected by a con- tinuous imperforate membrane, and the deep intervening grooves are filled up by a vesicular calcareous tissue, so that the sea-water could not have gained access to the mouths of the cells. The only explanation that I can offer is that the basal portion of the polyzoary may perhaps have been gra- dually overgrown internally by this layer of vesicular tissue, and may thus have been practically killed, whilst the upper portion remained open to the sea and genuinely alive. If this was not the case, I cannot explain the undoubted facts.
The enormous internal keels, whether free or connected together by membrane, give an extraordinary depth and thickness to the polyzoary ; and the fenestrules do not extend to more than about one fourth of this depth from the outside ; nor do the cells. In Hemitrypa, Phill., the fenestrules do not extend through the entire thickness of the polyzoary ; but in this genus the fenestrules are confined to the znner surface of the funnel-shaped frond, and the cells open externally. In Cryptopora, Nich., again, the outer and imner surfaces of the polyzoary are both imperforate, and the cells open into a central space, which is crossed by regularly placed pillars having a direction perpendicular to the plane of the frond.
The following is the only species of the genus Carinopora which has come under my notice.
Carinopora Hindet (Nicholson).
This being the only species of the genus, it is not needful to recapitulate its structural characters, since these, so far as known, have been fully discussed above. It only remains to give the measurements by which the species is distinguished, along with one or two characters which are not of generic value. ‘The only known specimen exhibits a portion of a very large infundibuliform frond, which, though fragmentary, has a height of four inches, with a diameter at the top of clearly more than half afoot. The actual base is broken off. About six branches occupy the space of two lines. The fenestrules are sometimes oval, sometimes hexagonal or polygonal; and their

arrangement differs in different parts of the frond. Sometimes they are disposed in regular diagonal lines; but even in this case there are often perceptible central longitudinal lines, on either side of which the diagonal rows of fenestrules diverge in opposite directions like the barbs of a feather, giving rise to a most peculiar appearance. At other times the fenestrules are rhomboidal, or hexagonal, or polygonal, and are not ar- ranged in distinct diagonal rows ; whilst two contiguous longi- tudinal rows are often separated by an unusually narrow and apparently quite straight branch (see fig. 2,c). The spaces along which the flexuous branches inosculate have a depth of about half a line, considerably exceeding the width of the branches; so that whilst seven fenestrules occupy a quarter of an inch measured diagonally, only four occupy the same space measured longitudinally. The thickness of the frond, measured at right angles to its plane of growth, is one line or a little more, nearly two thirds of this being accounted for by the great internal keels. Lastly, there are generally three cell- mouths to the length of a fenestrule, with two placed opposite the inosculation of each pair of contiguous branches.
The only known example of this singular species was dis- covered by my friend Mr. George Jennings Hinde, by whom it was submitted to me for examination, and in whose honour I have named it.

Up tothe present time about 134 species of marine fish are known to inhabit the shores of New Zealand. Of these, 51 (or 37 per cent.) are found nowhere else; 38 extend to the Australian and Tasmanian seas, but no further; six range to the Pacific islands, five inhabit South America, four South Africa, and one Kerguelen Land and the Auckland Islands ; there are also four others that are common to both Australia and South America, five common to Australia and South Africa, two common to Australia and the Pacific islands, and one common to Australia and the Auckland Islands. Thus the total number of our sea-fishes found in Australia is fifty, in South America and the Cape of Good

Hope nine each, three (Prosopodasys cottoides, Trygon Kuhlit, and Ostracion Fornasint) are not found nearer than the Indian archipelago (the identification, however, of the latter is doubt- ful), and one (Halargyreus Johnsoni) has been obtained. at Madeira only. The remaining thirteen are widely ranging species. ‘These 134 species have been distributed among 114 different genera, eleven of which are not found elsewhere. The connexion with Australia is here, as might be expected, so well marked that I need not dwell upon it, but will proceed to examine the affinities of New Zealand to other countries. Our former connexion with South America is indicated by Mendosoma lineata, Notothenia cornucola, Merluccius Gay?, and Genypterus blacodes; with South Africa by Trigla kumu, Gonorhynchus Grey, and Bdellostoma cirrhatum; while the occurrence of Gonorhynchus Greyi and Congromurena habenata at St. Paul’s shows that that little volcanic island was also probably connected. The occurrence in New Zealand of species belonging to the southern genera Pseudorhombus, Bovichthys, Agriopus, Chilodactylus, and Scorpis points to the extension of a former antarctic continent of which these islands formed a part; while Acanthurus triostegus, Dascyllus aruanus, Chanos salmoneus, Peltorhamphus nove-zealandie, a species of sting- ray allied to Trygon thalassia, and species of the genera Labricthys and Trachelochismus show an affinity for the islands of the Pacific.
‘[ have already remarked that three of our fishes are not found nearer than the Indian archipelago; and it is probable that our species of Torpedo and Doryichthys came from that direction also. But a still more curious affinity to Japan is shown by the presence of the genera Lotella and Ditrema, and of another little fish (Calloptilum punctatum) which is found at the mouth of the river Thames, and which has its nearest allies in the genus Bregmaceros from China and the Philippine Islands. Gonorhynchus Greyti and Clupea sagax are also both found in Japan, but they occur in Australia as well. Our species of Ditrema differs from D. deve of Japan in having teeth on ifs palate and a band of teeth in each jaw instead of a single row. Platystethus cultratum, from Norfolk Island, is also closely allied. This connexion with China and Japan is, I consider, the chief point of interest in the distribution of our marine fish.
In the genus Tripterygium, which is found only in the Mediterranean, we have an anomaly which is parallel to the cases of Fuligula and Mergus among the birds; and as we proceed we shall find many other similar cases cropping up.
The freshwater fish naturally supply more important evi-

dence as to the former distribution of land than those inhabit- ing the sea. Of these, New Zealand possesses fifteen species belonging to seven genera, of which six species, or 40 per cent., and one genus are found nowhere else. That the per- centage of the endemic freshwater fish should be nearly the same as that of the marine fish is a remarkable and unex- pected result; for the number of species of marine fish inha- biting New Zealand and found also in other countries de- pends partly on permanency of specific characters since New Zealand was isolated, and partly on the power possessed by fishes of migrating to us from other countries, while among the freshwater fish the proportion depends entirely on perma- nency of specific characters ; consequently this permanency of specific characters must be greater in freshwater than in salt- water fish ; and this is the more remarkable as our freshwater fish are far more variable, especially Galaxias attenuatus and Eleotris gobiotdes, than the marine; and Galaxias attenuatus, being found both in South America and in Tasmania, must have had a longer specific existence than any of the others. It is therefore evident that a great amount of variability is not inconsistent with great specific longevity under certain con- ditions. The conditions in this case are, [ believe, the absence of any large rapacious fish preying on the smaller variable ones, and thus tending to fix those varieties which are best adapted to elude the observation of the enemy. These condi- tions will soon no longer exist in our rivers, on account of the introduction of the trout; and I should like to draw attention to the fact that descriptions and figures of all the varieties of fish occurring now in one or more of our rivers would be a most valuable contribution to science as material for future naturalists.
Of our freshwater fish found beyond New Zealand, Retro- pinna Richardsoni is found in the Chatham Islands, Galaxias fasciatus in both the Chatham and Auckland Islands, Galaxias attenuatus in the Chatham Islands, Tasmania, Patagonia, and South America, Galaxias olidus in Australia, Anguilla auck- landii in the Auckland Islands, Anguilla australis in the Auckland Islands, Tasmania, and Timor, Anguilla latirostris in the Chatham Islands, Kurope, Egypt, China, and the West Indies, Geotria australis in Australia, and Geotria chilensis in Western Australia and Chile. Thus four of our freshwater fish are found in the Chatham Islands and three in the Auck- land Islands, which are all the freshwater fish known to in- habit those places ; three are found in Australia, two in T'asma- nia, two in South America, one in the island of Timor, and one is spread from China to Europe and the West Indies. The Aus-

tralian grayling also (Prototroctes marena), although a distinct species, much resembles our own (P. oxyrhynchus); and another closely related genus (Haplochiton) is found in South America.
The genus Lleotris is widely spread in tropical countries. Its head quarters are in the Indian archipelago; and it ranges west to Madagascar, east to Mexico and the West Indies, north to Japan, and south to New Zealand, but is not found in Africa. The nearest ally of our species (EZ. gobiotdes) is E. obscura from Japan and China.
The evidence, therefore, to be derived from the freshwater fish goes to prove that a close connexion has existed between Australia, New Zealand, and South America. The fact of two. species of the same genus of grayling being found in Australia and New Zealand respectively, while South America is inhabited by a closely allied but distinct genus, indicates either that our connexion with Australia was later than with South America, or that in the old continent New Zealand and Australia were inhabited by one, and South America by ano- ther species of the same family. The freshwater fish also prove that our connexion with the Chatham and Auckland Islands was much later than with Australia. The distribution of Anguilla latirostris, which is not found nearer than China*, adds its testimony to that of Lotella and Ditrema of a former connexion with that part of the world not by way of Australia ; and we shall find that this remarkable connexion with China and the Indian archipelago thus dimly shadowed out by the fishes, gets stronger and stronger as we review the invertebrate anunals.
MOoLuusca.
Of the New-Zealand Mollusca about 460 species are now known, of which about one half are found nowhere else. They show, as might be expected, a marked affinity with Aus- tralia, but are still very distinct. We miss Olivella, Vanikoro, Eutropia, Perna, Trigonia, and others; while Mitra, Colum- bella, Marginella, Natica, Scala, Conus, Cyprea, and Cardium are very feebly represented with us. On the other hand, Australia does not possess Buccinum; and Husus, Imperator, Purpura, Turritella, and Pecten are much less developed than in New Zealand. As, however, the affinity is decided, I shall here limit myself to pointing out our connexion with other countries.
Of Cephalopoda we possess eleven species, only two of which are peculiar to New Zealand. Onychoteuthis Bartlingii, Om- mastrephes Sloani, Nautilus pompilius, and Argonauta nodosa
* Dr. Giinther has lately described A. obscura, a closely allied species, from the Fiji Islands.
Relations of the New-Zealand Fauna. 89
are all found in the Indian Ocean, and the last two in the Pacific also, but none of them in Australia.
Of marine Gasteropods and Conchifera, omitting the marine air-breathers, we have 830 species, about 160 of which are endemic. Of these, Cyclina Kréyert, Mytilus magellanicus, and Anomia alecto are only found in South America, as also is the genus Solenella. Chione mesodesma is found at Valpa- raiso and the Philippine Islands, Barbatia pusilla in Peru and Australia, Myodora ovata in the Philippines and Australia, Mytilus smaragdinus and Anomia cyteum in China; while we also have a small Cyprea, which appears to me to differ from C. punctata (from the Philippines) only in the absence of red spots. Bankivia varians is found in South Africa and Tas- mania. Our common pipi (Chione Stutchbury?) is found in Kerguelen Land; while Ranella vexillum, which is also found in ‘Tasmania, is closely allied to &. argus from the Cape of Good Hope, and to R. proditor from St. Paul’s Island. The genera Phorus, Rotella, and Calyptrea are found in the Phi- lippine Islands and China, but not in Australia. The genus Lyonsia, of which we possess one species, extends from Europe and India to the Philippine Islands and Borneo, and is also found in Peru and the West Indies. A few of our shells are almost cosmopolitan, as Lucina divaricata, Saxicava arctica, Crypta unguiformis, and Lima squamosa; while Nucula mar- garitacea inhabits Europe, Dosinia subrosea is said to have been found in the Persian Gulf, and the genus Solemya is found only in Australia and the Mediterranean. While, there- fore, our marine shells show a decided affinity to Australia, they also show a slight connexion with South Africa, Ker- guelen Land, St. Paul’s, and South America, and point more decidedly to a connexion with the Philippine Islands and China.
Of land and freshwater shells, including the marine air- breathers, we possess 114 species, of which 97 are not found elsewhere. ‘These show many striking and important facts in distribution. Three only (felix subrugata, H. sydneyensis, and H. rapida) are found in Australia; and of these the second is so like ZZ. cellaria of Europe that it has only lately been distinguished from it by Dr. Cox, and is also closely allied to H. glaberrima from the Solomon Islands. Helix rapida is also found at Erromanga, one of the New Hebrides. /elix coniformis* inhabits the Louisiade Islands, HW. radiaria the

Solomon Islands, and 7. vitrea the Admiralty Islands. Cass?- dula mustelina is found at Singapore and Pulo-Penang, and Amphibola avellana in New Caledonia. But the distribution of some of the genera is more important even than that of the species. Nanina spreads from India to China, the Philippines, Indian archipelago, and Polynesia, and is also found in Mada- gascar and the Mauritius, but not in Australia. -Amphibola extends over Australia and Polynesia to Burmah. Lymnea extends from Europe to India, China, and Java, and is also found in North America, but not in Australia. Ass¢minea is found in England, India, Celebes, Molucca Islands, and the Navigator and Friendly Islands, but not in Australia. The : family Ancyline, or freshwater limpets, of which we possess two species, is found only in North and South America, Europe, and Madeira; and our common slug (Milax antipo- darum) belongs to a genus found only in Europe and the island of ‘Teneriffe. Testacella, of which we also possess a species, is only found in Europe and Teneriffe.
Our former connexion with Australia, however, is shown in the family of bitentaculate slugs (Janellide), a family which is found only in Australia and New Zealand—and also in the marine air-breathing limpets (Stphonaria), three of our species being foundin Australia and ‘Tasmania.
The land and freshwater univalves therefore show a stronger affinity to Polynesia and the Philippine Islands, by way of New Caledonia, the New Hebrides, Solomon Islands, and the Indian archipelago, than they do to Australia, although the distribution of the genusJanella shows that land communication once existed with Australia also. To South Africa and South America they exhibit no special affinity. Like the birds and fishes, they also show a slight anomalous affinity to Europe without any intermediate steps.
From the Chatham Islands eighty-two species of mollusks are known, of which nine appear to be peculiar to those islands ; the rest are all found in New Zealand, including Janella bi- tentaculata and Stphonaria scutulata.
I know of two shells only from the Auckland Islands (Patella tlluminata and Vitrina zebra), both of which are endemic.

MOLLUSCOIDA.
Of Brachiopods we possess eight or nine species, of which two only (Kraussta Lamarckiana and Magas Cuming?) are found in Australia, the latter being also reported to occur in China. The genus Phynchonella is only known living in the arctic portions of North America and Japan ; but this anomaly +

is not surprising when we remember that this genus existed during the Lower Silurian period; but it is interesting as af- fording us the clue by which other similar anomalies may be explained.
The New-Zealand Tunicata are as yet but little known. The genera Ascidia, Boltenia, and Botryllus are only found in Europe and North America. Doliolum denticulatum is found at the Molucca Islands.
Of the Polyzoa I am acquainted with eighty-nine species, of which thirty-one have been found nowhere else as yet ; but it is probable that their range is very imperfectly known. Twenty-three of our species are found in European seas, while the intervening tropical seas appear to be almost destitute of this form of life. The chief point of interest in our Polyzoa is the great development of the massive species of Cellepora and of the coral-like family Idmoneide, which recall to mind the crag formation of England. Indeed one of our species, Hornera striata, is found fossil in the Crag; it is, however, also found fossil at Oraki, near Auckland, in beds of still older date. Considering how little attention has been paid to our Polyzoa, the number of known species indicates a rich fauna ; and, indeed, the entire class seems to be more abundant in the southern than in the opposite hemisphere, and, like the petrels, contains many forms quite unrepresented in the north.
INSECTA.
No New-Zealand naturalist who has collected insects on however small a scale in Europe can, I think, fail to be struck with the paucity in New Zealand, not only of species, but, in some orders, of individuals also. It is remarkable that in this country, whose indigenous warm-blooded animals are limited to birds and bats, on entering the bush, instead of finding the masses of decaying wood and leaves swarming with life, we find hardly a living creature*, while at the same time we are attacked by myriads of bloodthirsty mosquitos (Culea acer). It would certainly seem that abundance of food does not pro- duce abundance of individuals in some orders (e. g. Coleoptera) ; neither does an absolute dearth of food in the ¢mago state pre- vent the increase of individuals in others (e.g. Diptera). The swarms of sand-flies (Simulium cecutiens), also, that greet us on the coast from the North Cape to the Bluff, where could they possibly have found food before the advent of man ? Where, indeed, do they find it now in sufficient quantities ?
* My experience in this respect in New Zealand is very different from that of Mr. Wallace in Singapore and Borneo, but similar to his in Celebes and Ceram.
92 Capt. F. W. Hutton on the Geographical
Of beetles about 200 species inhabiting the land are described, the whole of which, I believe, are found nowhere else. These species are distributed into about 110 genera, of which about 35 are peculiar to New Zealand. A remarkable contrast to this is shown in the water-beetles, of which four only are known, two (Cybister Hookert and Colymbetes rufi- manus) being, I believe, endemic, and the other two (Colymbetes notatus and Gyrinus natator) being found in Britain. The genera best represented are, Hlater with twelve, Keronia with eight, Mecodema with nine, Xylololes with seven, Cicindela with six, Anchomenus and Maoria with five each, and Coptoma with four species. Few beetles can be called abundant; the little green species (Pyronota festiva) so destructive to our fruit-trees, and a small brown species (Colaspis brunnea), common on the manuka (Leptospermum) in December and January, are perhaps the only two that deserve the epithet, although many can be called common. ‘The beetles as a whole are, according to Mr. Pascoe, most closely allied to those of Australia.
The Hymenoptera are very poorly represented, about eighteen species only being as yet known. All are, I believe, endemic. Most of the genera are widely spread; but Orecto- gnathus and Dasycolletes are peculiar to New Zealand. ‘The poorness of our fauna in this order cannot be owing to un- suitableness of climate; for the honey-bee (Apis mellifica), which was introduced about thirty years ago, has spread over both islands *.
The Diptera are more numerous than the Hymenoptera, sixty species being known. This is just opposite to what obtains in most countries, including Australia and South America. Of these, Z¢pula senex is found in Australia, Musca tattienstis in Polynesia, and Musca lemica in both Australia and Polynesia. Although most nearly allied to Australia, our dipterous fauna must have been derived from other localities as well; for the genus Diphysa occurs only in Mexico and Brazil, Actiéna in Europe, Cenosia and Sapromyza in Kurope and North America, and Opomyza in Europe and the Mauri- tius. No genus is endemic. Of the earwigs we possess one endemic species (orficula littorea), found only near the sea- shore.
Of the Lepidoptera I know hardly any thing, and _ prefer waiting until Mr. Fereday has published his promised descrip- tions of the species before examining their bearing on the present subject. But one fact stands out prominently, viz.
* Mr. W. T. L. Travers informs me that the honey-bee was introduced into Nelson in 1842, and that wild bees were common in 1850,
s , 4 f

that out of more than three hundred species only eight belong to the butterfly section (Fereday, Trans. N. Z. Inst. iv. p. 217), and several of these are world-wide stragglers.
Of Neuroptera about fifteen species are known. Of these, Perla opposita is found in ‘Tasmania, and our representative of the white ants (Calotermes ‘nsularis) in Australia. This order appears to have more affinity with Tasmania than with Australia; and it is remarkable that the wide-spread genus Perla, which is found throughout North and South America, and from Europe through India to China and Japan, is also found in New Zealand aud Tasmania, but not in Australia. Leptocerus has also the same range, with the exception of not being known in China and Japan. Hermes extends from India to China and Java; it is also found in tropical Africa and South America, but not in Australia or Tasmania. Palingenia is found in Europe, India, North Africa, and North and South America, while Philanisus is peculiar to New Zealand. The Heteroptera are remarkable for their fragmentary character and wide distribution, The thirteen known species belong to thirteen different genera and nine families. Arma Schellenbergii is found in Australia and the Philippine Islands, Cermatulus nasalis in Australia and Tasmania, Platycoris immarginatus and Rhaphigaster Amyote in Australia, Lygeus pacificus in Australia, Tasmania, and India, and Nysius zelandicus in Tasmania—thus leaving not more than seven endemic species, three of which have not yet been properly examined, and may therefore be found to be identical with species inhabiting other countries. One of the endemic species (hopalimorpha obscura), however, belongs to a genus found nowhere else.
In strong contrast to this stand the Homoptera, which in- clude nineteen species, all endemic and belonging to two genera only, Cicada having twelve and Cixius seven species.
The number of species of Orthoptera I do not know ; but in comparison with other orders it is well represented by both winged and wingless members; and the genera, as a rule, con- tain several species.
Whilst, therefore, the insect fauna as a whole shows its greatest affinity towards Australia, it also exhibits a connexion with other countries, more especially China and Europe. But the most remarkable fact is the great difference shown in this respect by the different orders. Whilst the Diptera, Neuroptera, Homoptera, and Orthoptera present the appear- ance, in part at least, of an old fauna, the Heteroptera are nearly all stragglers; and this strongly suggests the inference that at the time of the spreading of the former orders the
Ann. & Mag. N. Hist. Ser. 4. Vol. xiii. 8
94 Capt. F. W. Hutton on the Geographical
Heteroptera were not in existence. The same thing is seen in the difference between the moths and the butterflies, sug- gesting also that the latter were developed at a later period than the former; and there can be no doubt that when our insects are better known a careful comparison of them with similar faunas of other countries will afford a most instructive lesson.
With the exception of the Indian (Blatta orientalis) and American (B. americana) cockroaches, neither of which are common, the flea (Pulex irritans), the bed-bug (Cimea lectu- larius), several Aphides, the slugworm (Zenthredo cerast), and the house-fly (Musca domestica), | am not aware of any insect that has been introduced unintentionally by man during the progress of colonization; for the ring-legged mosquito, which is supposed in Auckland to have been intro- duced by the troops from India, belongs to a species (Culea argyropus) not found elsewhere, and was sent home by Dr. Sinclair before the troops arrived. The only exceptions may perhaps be :—the black field-cricket, which, although inhabit- ing fields with us, and but rarely entering houses, appears to be identical with the house-cricket of Europe (Acheta domestica) and to have spread quite lately; and also a small dark-brown beetle belonging to the genus Hlater, which is abundant in Auckland, but, to the best of my knowledge, is not found more than twenty miles out of that town.
MyYRIOPODA.
Of Centipedes nine or ten species are now known, all of which are endemic. The genus Lithobius extends from North America, Europe, and North Africa to Singapore, but is not found in Australia ; Henicops is found only in Chili and Tas- mania, Cryptops only in North America and England; while Cermatia and Cormocephalus have wider ranges and are both found in Australia.
ARACHNIDA.
Of Spiders we have about 100 species; but my knowledge of them is very limited. Mr. Pickard Cambridge, in a letter to me, remarks, “all the spiders you now send [from the Auckland province], except one or two, are strikingly Euro- pean in appearance, nothing tropical-looking among them.” Perhaps the most remarkable fact is the occurrence in the Chatham Islands of a species of water-spider (Argyroneta), of which only one other species, inhabiting Europe, is known. Spiders are very numerous in New Zealand, owing no doubt to the abundance of Diptera, on which order they chiefly prey.
CRUSTACEA. Of Crustaceans 106 species have been described as coming

from New Zealand ; but my knowledge of this class also is at por very limited. Professor Dana has remarked that New
ealand has a greater resemblance to Great Britain in its Crustacea than to any other part of the world ; but our common salt-water crayfish (Palinurus Lalandit) is found at the Cape of Good Hope and the Island of St. Paul.
ANNELIDA.
Our marine Annelids have up to the present been almost entirely neglected. Of terrestrial forms we have two species of earthworm (Luwmbricus) and a member of the peculiar genus Pertpatus, found only in South America, the bape of Good Hope, and the West Indies.
SCOLECIDA.
The most remarkable fact in this class is the occurrence of two or three species of land-Planarians, the so-called “ land- leeches,” one or two of which belong to the genus Bipaliwm, found only in India, China, and Japan.
ECHINODERMATA.
Of Echmoderms we have seventeen species of starfish, eight sea-urchins, and eight Holothurians. Of these, twelve starfish, six sea-urchins, and all the holothurians appear to be endemic. Of the others, Ophionereds fasciata is found at the Chatham Islands, Pentagonaster pulchellus at the Chatham Islands and in China, Othilia luzonica in the Philippine Islands and Vera Cruz; while we also possess species ap- parently identical with Astropecten armatus of South America and Henricia oculata of Europe. It is worthy of special remark that although Australia possesses several species of Pentagonaster, the Chinese species is not found there; so that it must have migrated to us direct, and not have come wd Australia. We also possess a species of Pteraster, a genus found only in South Africa and northern seas. Of the sea- urchins, Cidaris tubaria and Echinobrissus recens are both found in Australia ; but the latter appears to be very rare in New Zealand, as I have only seen one specimen, which is in the Colonial Museum.
CaLENTERATA and PROTOZOA.
Of these very little is known. Our seven species of corals are all peculiar, as also appear to be many species of Sertula- rians and sponges ; but I know of no facts among these lower animals that will help out the present investigation, except in the case of Cryptolaria, a genus belonging to the family Ser-

tulariide, and consisting of two species—one of which is found in New Zealand, and the other in Madeira.
SUMMARY.
If now we review the evidence adduced, and select the more important points, we find in the distribution of the Struthious birds, the frogs, freshwater fishes, several shells (such as Cyclina Kréyert, Mytilus magellanicus, Anomia alecto, Bar- batia pusilla, Chione Stutchburyt, and Ranella vewillum), in the genus Henicops among the Centipedes, and Peripatus among the Annelids, evidence of a former great extension of land in the southern hemisphere; for these cases cannot all be accounted for by drifting icebergs. With the exception of the shells and two freshwater fishes, no species, however, is common to New Zealand and South America on the one hand, nor to New Zealand and South Africa on the other; for I omit from consideration the species of marine fish, as they might perhaps have crossed at a later date. In the frogs the genera, and in the birds the families are different. This perhaps in- dicates a very long interval since the separation of these countries took place; but differentiation of form, even in closely allied species, is evidently a very fallacious guide in judging of lapse of time, and a surer one is afforded us in the absence of Mammalia from New Zealand ; for it is evident that if the marsupials that now inhabit Australia, or the placental mammals that inhabit South America, had been in existence at the time of the distribution of the Struthious birds, some members would have found their way to New Zealand, and would have remained upon it with the moas. This antarctic continental period must therefore have preceded the spread of the Mammalia into the southern hemisphere. Besides this continental period we have evidence in Hudynamis taitiensis, Naultinus pacificus, Amphibola avellana, Musca taitiensts, and in the genera Ocydromus and Nestor, of a Polynesian conti- nent quite unconnected with Australia, but including Lord- Howe Island, Norfolk Island, and New Caledonia; while by Helix coniformis, H. rapida, H. radiaria and H. vitrea we can prove a close connexion with the New Hebrides, Solomon Islands, Louisiade archipelago, and the Admiralty Islands, By Nanina among land-shells and Asstminea among fresh- water shells, we prove a connexion also with the Navigator and Friendly Islands ; and these genera take us north through the Molucca Islands, Celebes, Borneo, and the Philippines to China, where we again come across many New-Zealand species and genera. ‘he most important are :—Ditrema, Torpedo, and Anguilla latirostris among fishes; Mytilus smaragdinus, Phorus, Rotella, Calyptrea, Cassidula mustelina, Lymnea, and

Lthynchonella among shells ; Perla and Hermes among insects ; Lithobius among centipedes ; Bipalium among the Scolecida ; and Pentagonaster pulchellus and Othilia luzonica among the starfish,—none of these, it must be remembered, being found in Australia. The absence of Mammalia, however, in New Zealand shows that this line of communication was never con- tinuous land; but the absence from Australia of the forms that I have mentioned shows that the connexion along the whole line was closer at every point than it was with that continent ; and this leads to the further conclusion that this line of com- munication existed at a later date than the connexion of New Zealand with Australia.
The close relationship of the Chatham and Auckland Islands in all their natural productions to New Zealand, and the far greater difference between New Zealand and the islands more to the north, as well as the large number of species of moa lately inhabiting these islands, show that another and smaller continent, or perhaps a large island, existed at a still later period, but has since subsided ; and this must bring us nearly to the recent period, or the difference between New Zealand and the Chatham Islands would be greater.
The geographical distribution, therefore, of the New-Zealand fauna points to the following conclusions :—
1. A continental period, during which South America, New Zealand, Australia, and South Africa were all connected, al- though it is not necessary that all should have been connected at the same time ; but New Zealand must have been isolated from all before the spread of the mammals ; and from that time to the present it has never been completely submerged. This con- tinent was inhabited by Struthious birds and by Hymenolai- mus, Notornis, Hinulia, Mocoa, Galaxias, Prototroctes, Lio- pelma, Janella, Amphibola, Henicops, and Peripatus, and further to the north by Megapodius—and probably also by many forms peculiar to New Zealand, such as Strigops, Keropia, Xenicus, Heteralocha, Anarhynchus, Naultinus, &c. Of course in mentioning these names I do not mean that all the forms were the same then as now, but that the ancestors of these genera lived on the old antarctic continent.

Subsidence followed; and the evidence then points to a second continent stretching from New Zealand to Lord-Howe Island and New Caledonia, and extending for an unknown distance into Polynesia, but certainly not so far as the Sand- wich Islands. ‘The fact of mammals being found in the New Hebrides, Solomon Islands, and New Ireland shows that be- tween New Caledonia and the New Hebrides a narrow strait must have existed cutting off land communication ; but these were connected with China, either directly or by a chain of

islands. This second continent received from the north those forms already enumerated, together probably with Sphenwacus, the rails, and the starlings; at the same time it received from Australia the honey-eaters, Certhiparus, Gerygone, Petroica, Rhipidura, and others, and from that time to the present has been occasionally receiving additional birds. It will also be noticed that very few of the birds of the middle paleeotropical region came down this line of communication, no pheasants, woodpeckers, grackles, or finches; while Australia, in its wood-swallows (Artamus), pittas, quails, and numerous finches, shows now some affinity to this region. This can be best ex- plained by supposing that the New-Zealand line of communi- cation was broken up before these birds came into existence, and that further changes have since taken place in the lines of easiest communication ; indeed the fact of such forms as the elephant, tiger, and bear being found in Sumatra and Borneo, marsupials in Celebes, the Moluccas, Solomon Islands, and New Hebrides, and the presence of an emu in New Guinea, and a cassowary in Australia, prove that changes in the dis- tribution of land have since taken place ; but it is foreign to the object of this paper to speculate on these here. This second continent was also inhabited by most of the orders of insects, although perhaps not in great abundance; but He- teroptera and the butterfly section of the Lepidoptera were absent.

GEOLOGICAL EVIDENCE.
Such are, I think, the deductions that may be fairly drawn from a study of our fauna. It remains now to examine the geological and paleontological evidence, and see whether it agrees with that derived from zoology, and then to try to fix with as much accuracy as possible the dates of the principal movements of the earth’s surface which have gradually led to the present state of the New-Zealand fauna.
Hardly any thing is yet known of the paleozoic rocks of New Zealand. ‘The earliest fossil shells described are almost identical with those living in Europe during the Triassic period; but the only known plant is Dammara australis

(Hochstetter’s ‘ New Zealand,’ p. 57), a genus still living in New Zealand, but also found in Australia, New Caledonia, New Hebrides, Fiji, and the Indian archipelago.
An interval then occurs; and the next formation probably belongs to the Jurassic period. In this we find Belemnites aucklandicus, which can hardly be distinguished from B. ca- naliculatus, and Astarte wollumbillaensis. The ferns, too, found so plentifully near Port Waikato, in the Clent hills, at the Mataura, and at Waikawa harbour are considered by Pro- fessor M‘Coy to be identical with Australian ferns from the same formation. At the close of this period movements on an extensive scale commenced in New Zealand; the land was up- heaved, and an extensive mountain-chain formed. A long blank now occurs in our geological record (see Geol. Reports, 1872, p. 105), the next formation belonging to quite the uppermost part of the Secondary epoch, later, I believe, than the white chalk of England. In it we find remains of dicoty- ledonous plants and large Saurians belonging to the genera Crocodilus? and Plestosaurus. Here, also, we tind three fossil shells (Dentalium majus, Lucina americana, and Cucullea alta) similar to those found in South America, one of which, Lucina americana, is found in the Lower Cretaceous rocks of Tierra del Fuego, and the other two in the Miocene formations of Patagonia and Chile—thus showing that during this blank in our geological record an intimate connexion had existed be- tween New Zealand and South America. The disposition, however, of these beds shows that the New-Zealand Alps were not submerged. A long interval now follows, during which New Zealand was again upheaved; and the next rocks that we find are of Upper Eocene date (Geol. Reports, 1872, p. 182). From that time until the close of the Miocene period New Zealand was greatly depressed and divided into several islands; but at the close of the Miocene period it was once more upheaved. During this period we find several South- American Miocene shells not met with in the older formation, as well as several Australian ones. During the Newer Plio- cene period it again subsided, and the Wanganui beds were deposited. From that time I can see no evidence of the land having ever stood at a higher level than it does at present ; but as the later changes in the physical geography of New Zealand have a most important bearing on the present condi- tion of its fauna, beyond the scope of my present inquiry, I pro- pose treating the subject in a separate paper*. The geological evidence is therefore that since the Jurassic period there have
* Vide On the Date of the last Great Glacier Period in New Zealand” (Trans. New-Zealand Institute, vol. v.).
* 100 Capt. F. W. Hutton on the Geographical
been three principal upheavals in New Zealand, in the Lower Cretaceous, Lower Eocene, and Older Pliocene periods respec- tively, and that these were divided by two insular periods, viz. during the Upper Secondary (Danian) and from the com- mencement of the Upper Eocene to the close of the Miocene, thus agreeing completely with the zoological evidence.
The dates assigned by the geological evidence also agree well with those derived trom zoology. We have seen that it is necessary to suppose that the first great antarctic continental period was anterior to the date of the spread of the mammals southwards. Nowa few marsupials are known in the Triassic period; but it is quite possible either that they spread very slowly, or that barriers existed that prevented any southward migration. In the Eocene period, however, some placental mammals were in existence, although marsupials (not of Aus- tralian types however) still formed in Europe the principal mammalian life ; and if the supposed barriers to a southward migration were still in existence, we know, from what hap- pened in the northern hemisphere, that the whole, or nearly the whole, of the marsupials would be exterminated. The marsupials, therefore, must have migrated south not later than the Eocene period; and as we know that our connexion with Australia and South America must have been before that migration, it follows that the first, or Lower Cretaceous, period of upheaval must have been the time of the antarctic continent. This is rendered still more probable by the fact that our Jurassic fossils show a connexion with Australia only, while our Upper Secondary fossils show for the first time a relation to South America. The fact, too, of the Cretaceo-Oolitic rocks of Tierra del Fuego having been largely disturbed, metamorphosed, and broken through by dykes of greenstone, shows that extensive elevatory movements have taken place there also since they were deposited. It is therefore to the Lower Cretaceous period that we must probably look for the time of the dispersion of the Struthious birds. With regard to the date of the second or Polynesian continental period, the only zoological evidence we have is that it probably preceded the wide dispersion of the Hemiptera and the butterfly section of the Lepidoptera. This, therefore, could not have been later than the Eocene; for a fossil butterfly (Vanessa pluto) has been found in the Lower Miocene deposits of Radaboj in Croatia, and fossil Heteroptera in the Miocene beds of iningen in Switzerland. ‘The elevation during the Lower Eocene period was therefore probably the one which formed the con- tinent that I have described as including New Caledonia-and some of the Pacific islands. At this period probably Northern

Australia was submerged, and the southern portions of Aus- tralia and Tasmania formed one large island; while New Guinea, including the Solomon Islands and New Hebrides on the south and the Molucca Islands on the north, formed an- other large island, divided from the New-Zealand island or continent by the straits between New Caledonia and the New Hebrides.
This was the time of the migration from China southwards ; and it is worthy of notice that at the same time a large ocean existed from Southern Europe to China, in which the nummu- litic limestone was being deposited. Would it be too bold to speculate that it was along the shores of this ocean that those fish, crustaceans, and shells migrated which are now found in the North Atlantic or Mediterranean on the one hand, and in China or Japan on the other, but not on the southern shores of Asia, and that the anomalous distribution of European forms of fish, shells, &c. in New Zealand may be traced to the same route? This same period of sea communication between Europe and Japan will also probably have been the time of the land connexion that once existed between India, Madagas- ear, and Africa (the Lemuria of Dr. Sclater), as proved by the recent freshwater fish and birds, as well as by the Miocene mammalia*; and to this period we may also refer the origin of the curious affinity between some of the birds of Celebes and Africa. The long insular period during the Upper Eocene and Miocene times will therefore be the period of specific change in the moas, while the Older Pliocene upheaval will be the time of the mingling of the various species in New Zealand and the peopling of the Chatham and Auckland Islands. The Newer Pliocene was the time when the two islands of New Zealand were divided, and also the period when the Chatham and Auckland Islands were separated from them; but the latter occurrence probably preceded the former by a long interval.
Such appears to me to be the hypothesis most capable of accounting for the present fauna of New Zealand.
The objection, however, may be fairly raised that, if it is true, evidence of its truth ought to be also found in the flora of the country, which is not the case. I fully acknowledge the force of this argument, but think that some slight evidence can be found in the phenogamic flora. The distribution of

102 Mr. F. Bates on New Genera
Eucalyptus, for instance, is somewhat parallel to that of the marsupials, and can be only explained in the same way. Stilbocarpa polaris has its nearest allies in China and the Himalaya Mountains; while the distribution of Metrosideros, Ligusticum, Angelica, and, perhaps, Veronica implies a con- nexion between New Zealand and Asia not by way of Aus- tralia. This connexion is obscured by the great preponder- ance of Australian and South-American forms, but still fur- nishes an indistinct copy of the bolder outline sketched out by the fauna. This is owing to the wider distribution of genera among plants than among animals; and to me it appears to prove that the flora of a country, as a whole, is of a more ancient date than its fauna. Among the cryptogamic plants no trace of this outline can be discerned, as also is the case with the lower classes of the animal kingdom, owing to the genera having been, so to say, universally spread before the last mi- gration from Asia took place.
That the facies of a fauna and flora should date back from so long a period as I suppose, is certainly at variance with or- dinarily received opinion ; but from a study of the fauna and geology of New Zealand I do not see how we can escape from the conclusions that I have arrived at. I am well aware, however, that much more has to be done in the geology and natural history not only of our own islands, but also of the sur- rounding countries, before they can be considered satisfacto- rily proved; but I think that it will be easier afterwards to prove this hypothesis, or to disprove it and point out a more correct one, than it would be to detect it if the discussion had been postponed to a future period, when the more salient points will probably be obscured by the mass of facts which will then have accumulated. Such, at least, is my hope; but whether I am mistaken or not I leave others to judge.

[Concluded from p. 24, ] Tirana, Erichson.
For the better understanding of the two new genera that follow it is necessary to add to the published descriptions of the genus 7itena as follows :—Prosternum narrow and very

abruptly elevated between the coxe, a little concave in front of them, the extreme anterior portion always distinctly hori- zontal: prothorax very convex, slightly but distinctly rounded at the sides, lobed at the middle of the base, and very strongly and deeply punctured : lateral reflexed margins of the elytra distinctly continued along the basal margin up to the scutellum: the punctuation of the surface more or less irregular, with the interstices more or less strongly, transversely, and reticulately rugose ; and the body is ordinarily distinctly pilose.
Titena columbina, Exichson.
The colour in this species varies from purple to green, the front margin of prothorax and sutural edging of elytra being ordinarily of some shade of green ; sometimes, however, it is coppery, golden, greenish cyaneous, &c.; the reflexed lateral margins are generally (except at the apex) of the same colour as the sides of the elytra; the legs are of a more or less dark piceous, sometimes with a green tinge. The head and prothorax are more or less closely covered with deep punctures, the latter slightly but distinctly rounded at the sides; the elytra are rather strongly punctured, with a disposition to a seriate arrangement; the intervals distinctly transversely and some- what reticulately rugose ; and the body is distinctly pilose.

Lateral reflexed margins of the elytra distinctly terminating at the humeral angle; the punctuation of the surface of the elytra is in rows of fine punctures, the intervals being convex, interrupted, and forming, especially at apex, series of oblong tubercles. Legs longer and (especially the tarsi) more slender. Body not pilose.
Artystona Erichsoni, White (Titena).
The Titena interrupta, Redtenb., must be referred to this species, the type specimens of which are in my collection.
The head is remotely punctured ; the prothorax more closely punctured, with the interstices quite smooth.

Artystona Wakefieldi, n. sp.
Readily to be distinguished from A. Hrichsont by the colour entirely of a dark shining brown; the head and prothorax much more closely and rugosely punctured; and, as a secondary character, the intervals on the elytra (especially at sides and apex) are more strongly interrupted and more distinctly tuber- culiform.

CALLISMILAX, n. g. Differs from Titena in the prosternum being vertical and

widely concave in front, direct from the anterior border, and much wider (and usually concave) between the coxe; the process wider, more or less horizontal, and frequently widely concave or excavated down its length, with the lateral margins upturned, the end more or less prominent and broadly rounded or truncated. The prothorax moderately convex, subquadrate, wider at base than at apex, broadly rounded or lobed at base, and always more or less finely punctured. The reflexed lateral margins of the elytra distinctly terminate at the humeral angle ; the punctuation of the surface of the elytra is ordinarily fine, distinctly seriate or not, the intervals more or less flat ; sometimes, however, the punctuation is more or less foveate, the intervals more or less convex and confluent. The body is not pilose; the form is varied, but never so cylindric as in Titena. The eyes above are sometimes rather narrow and oblique; the convexity of the elytra, the stoutness of the legs, the length of the tarsi, &c. are also subject to specific variation.
The form of the prosternum and the totally different style of sculpture on the elytra will at once serve to distinguish this genus from Artystona.
Callismilax enea, Montrouz. (Strongylium).
Elliptic. Entirely of a brilliant brassy green above. Head and prothorax finely, clearly, and not very closely punctured ; the latter distinctly emargiate in front; the angles slightly prominent, distinctly broader at base than at apex; sides slightly incurved from the front to the hind angles: elytra finely and irregularly punctured, the larger punctures mani- festing a disposition to a seriate arrangement, especially at the sides and towards the apex; punctuation obsolete at apex; intervals shortly costiform at apex: underside bronzed green ; legs rather stout, steel-blue or violet; intercoxal process sparsely punctured : eyes above subrotundate: prosternal process sub- horizontal, feebly rugulosely punctured, broadly and obliquely concave or excavated; the sides upturned, and angulate between the coxee: mesosternum a little declivous and arcuately concave in front.

There are some points of resemblance, especially in the form of the head, between this species and the Cymbeba dissimilis of Pascoe; and, did I hold that genus unmistakably distinct from Adelium, I might be inclined to place this with it as a second species. It has not, however, the produced and pointed prosternal process, the distinctly marked-off epipleuns of the

elytra, nor the apically rounded intercoxal process, as_ in Cymbeba dissimilis. I possess examples of this latter coming from Cape York, New Hebrides, and New Caledonia.
Pheloneis harpaloides, White (Adelium).
This genus was created by Mr. Pascoe (Journ. of Entom. ii. p. 488) to receive the Adeliwm harpaloides of White. The Amarosoma simulans of Redtenbacher I believe to be the same thing. According to my view it cannot be separated from Adelium, which is evidently a polymorphous genus. Should this view be correct, the name will require changing, there being already an Adelium harpaloides, Boisduval; I should suggest the name amarotdes for it. The male of this species has the lower edge of the four hind femora emarginate and fringed with long hairs.
Messrs. Gemminger and Von Harold, in their great Cata- logue, have included the species in the genus Pseudhelops of Guérin. This is manifestly wrong, Pseudhelops having, amongst other differential characters, the penultimate joint of the tarsi simple, not subbilobed. The same authors have most unwarrantably sunk the genus Coripera of Pascoe under Pseud- helops; Coripera is evidently a good genus, very near to, but quite distinct from, Adelium. =

No. IX. On Ostracoda taken amongst the Scilly Islands, and on the Anatomy of Darwinella Stevensoni.
[Plates [V. & V.]
In undertaking a dredging excursion to the Scilly Islands, concerning the marine fauna of which we were unable to ob- tain previously any very accurate information, we anticipated finding, at any rate in the more sheltered nooks of that archi- pelago, a field of exploration comparable in character and richness to many of the better-known hunting-grounds of the south and south-west of England. In this, however, we were disappointed. In no part did we find any great profusion of animal life, and on the whole the district impressed us as being the most barren and hopeless for the purpose of dredging of any which we have hitherto explored. Our stay at St. Mary’s was cut short by the sudden advent of stormy weather; but we nevertheless obtained dredgings from many of the most promising spots in the neighbourhood of the principal islands ; nor do we believe that a protracted visit would have materially altered the character of the.result. We propose in this place to record the marine Ostracoda which occurred in the various dredgings ; and we may also state that an examination of the fresh- and brackish-water ponds on the islands of St. Mary and Tresco did not afford any other than species commonly found in such localities in England.
The number of species of marine Ostracoda is sixty-seven, of which three (or four?) are new to science; but the general
Ostracoda of the Scilly Islands. 115 aspect of the group is such as we should expect in any average British dredging. ‘There is a distinct absence of the charac- teristic northern forms, and an almost equal want of such species as Cythere emaciata, Bairdia acanthigera, &c., which find their greatest development on the south coast. Cythere lutea, a common species of both the littoral and laminarian zones in most (and more especially in the northern) districts of Britain, is also wanting.
The following list embraces all the species found in our dredgings amongst the Scilly Islands, and in a littoral gather- ing of muddy sand from St. Mary’s. The localities dredged were as follows:—off Porcressa Bay, St. Mary’s, 20-30 fathoms, hard sand; 8.W. off St. Agnes, 40 fathoms, hard sand, rock, and nullipore; inside St. Mary’s and St. Agnes, 8-10 fathoms, hard sand; New Grimsby Harbour, 10-14

Xestoleberis labiata, n. sp. Pl. IV. figs. 8-15.
Carapace of the female, as seen from the side, oblong, subtri- angular, highest near the middle; height equal to rather more than half the length: anterior extremity narrow, sharply rounded off ; posterior wide, obtusely rounded : superior margin well arched ; inferior nearly straight, but produced downwards towards the posterior extremity into a bulging prominence. Seen from above the outline is broadly ovate, tapering rapidly in front to an acute point, and very broadly rounded behind ; greatest width equal to the height, and situated behind the middle. The shell of the male seen laterally is more slender, and less tumid behind ; seen from above it is much more com- pressed and widest near the middle, the posterior extremity being somewhat narrowly rounded. The surface of the shell is smooth, distantly studded with small elevated round papillee. The chief peculiarity of the species, however, is a remarkable labiate projection of the postero-inferior angle of the shell, - which is more distinctly visible on the right valve (fig. 15). Length 35 inch.
Xestoleberis labiata was dredged in New Grimsby Harbour on a bottom of muddy sand, in a depth of about 14 fathoms.
Cytherura fulva,n. sp. Pl. IV. figs. 1-5.
Carapace of the female very tumid; seen laterally sub- quadrate, broadly rounded in front, produced behind into an obscure rounded subcentral beak: superior margin evenly and very slightly rounded, sloping steeply backwards towards the posterior extremity ; inferior nearly straight, simuated in front of the middle: greatest height situated in the middle and equal to rather more than half the length. Seen from below the outline is very broadly ovate, widest in the middle, the width being somewhat greater than the height; anterior extremity broadly rounded, with a distinct central mucro, posterior also broad, but tapering to a subacuminate central point. Shell of the male seen laterally much more elongated, with nearly straight dorsal and ventral margins, the height equal to scarcely half the length; the outlne as seen from below is also much more compressed. Surface of the shell obscurely reticulated and dotted, marked also, especially on the inferior surface, with faint longitudinal furrows. Length =! ich.
C. fulva was dredged pretty abundantly on a bottom of hard granitic sand, ina depth of 10-40 fathoms, off St. Mary’s and St. Agnes.

Surface of the shell smooth. Length =; inch.
A few specimens of this species were dredged at New Grimsby Harbour and inside St. Mary’s in depths of from 10-15 fathoms.
Note on the Anatomy of Darwinella * Stevensoni.
Our first descriptiont of this curious Kntomostracan being made from specimens which had been dried, and in which the contained animal could be very imperfectly seen, was incorrect in several important particulars. We propose now to rectity as far as we can our former errors, having, through the kind- ness of the Rev. J. Gunn of Norwich, been supplied with spe- cimens of Darwinella in the fresh state. To that gentleman we wish here to express our cordial thanks for the assistance which he has both now and on other occasions given to us.
From the details of structure given below it will be seen that Darwinella occupies a position intermediate between the two families Cypride and Cytheride, though more nearly approaching the latter family. The points of divergence are

found chiefly in the mouth-apparatus ; but the lower antennz also are abnormal, being quite destitute of the poison-gland and urticating sete of the Cytherida. The mandible differs much in structure from any similar organ known to us in either family. The first pair of jaws presents no special pecu- liarity ; but in the second pair (which in the Cytheridz is converted, by the great development of the palp and atrophy of the jaw-apparatus, into a simple foot with a mere trace of its jaw origin in the form of a few bristles) we find a pediform palp extremely well developed, combined with a large jaw, which is armed with cutting-teeth and bears a fully developed branchial plate. ‘The palp of the second jaw we described in our former paper as the “ first foot;”’ the mandibles and first pair of jaws were also misunderstood, and indeed had not then been seen except very imperfectly. The following description gives, we believe, a true account of the structure of the animal :—
Antenne very short and stout, strongly armed with curved claws and bristles: superior antenne six-jointed, having all the joints as broad as or broader than long, and beset with short curved sete ; inferior four-jointed, of nearly equal thick- ness throughout : apex armed with four or five strong, slightly curved, claws; entirely destitute of poison-gland or urticating sete, the place of which is occupied by a simple curved seta of moderate length. Mandible (PI. V. fig. 8) broad, truncate at the free extremity, which is provided with six or seven small, slender, spiniform teeth; palp three-jomted, its basal joint very wide, beset with a series of nine curved sete, and giving attachment to a small subcrescentic lamina which is fringed with about ten branchial filaments; second joint slender, nearly four times as long as broad, slightly curved and dilated at the distal extremity, where it bears one long and two small sete ; terminal joint more slender, about two thirds the length of the foregoing, and bearing at its truncate apex about six slender curved spines. Grasping portion of the first jaw (Pl. V. fig. 9) divided into four short setiferous segments, and bearing a very large oblong palp, which is fringed above with about twenty-four long branchial filaments, and has also four long deflexed sete attached near its base. Second jaw (Pl. V. fig. 10) simple, short and wide, truncate at the apex, and divided into several slender curved spines, bearing a large three-jointed pediform palp and an ovate branchial appendage of moderate size. Two pairs of feet of moderate length, five- jointed; the second pair much the longest, and having the last joint armed with one long and two small curved sete ; first three joints of nearly equal length, fourth and fifth respectively

about one half and one third as long as the preceding. Abdomen ending in a short conical process. Copulative organs? of the male of complex structure, the basal portion on each side con- sisting of a subrhomboidal acuminate lamina, the apical portion of an irregularly shaped plate produced laterally into an aliform process, and on the distal margin into a short strong hook.

XVI.—On the Generic Affinities of the New-England Chitons. By Pup P. Carpenter, of Montreal*.
Ir has been common, with conchologists even of the “ ad- vanced” school, to call every mollusk with eight valves a Chiton, except the vermiform species, which Lamarck sepa-

120 Mr. P. P. Carpenter on the Generic
rated as Chitonellus. The consequence has been that very little is known of most Chitonide except the external cha- racters—the differentiation shown in the soft parts, and even in the shelly valves, having been overlooked.
We have been fortunate, during the explorations of the U. S. Fish Commission, in observing four species alive ; another was taken alive at Eastport last year; a sixth has been cap- tured on the southern coast. These are all as yet known to inhabit the American Atlantic seas from Labrador to Florida. A seventh, called Chiton cinereus, is said to have been taken alive by Dr. Pickering, and to be in the collection of the Philadelphia Academy of Natural Sciences ; but it may prove to belong to one of the other species, or to be a ballast specimen.
The six authentic species present well-marked characters, ranging under five genera.
It may be premised that the Lamarckian genus Chiton was first divided by the Rey. L. Guilding according to the ex- ternal characters of the West-Indian species. About the same time the Rev. T. Lowe published the peculiarities in the in- sertion-plates of the British species. Both papers appeared in the ‘ Zoological Journal.’ Dr. Gray, however, was the first to present, in the ‘ Proc. Zool. Soc.,’ a full description of the forms of Chitonide, accurately arranged under genera and sections, partly according to the external, but principally according to the internal characters. Mr. Henry Adams, in compiling the ‘Genera’ from H. Cuming’s collection, was not allowed to examine the insertion-plates. He thought he saw, however, a correlation between the internal and external marks, and accordingly redescribed Gray’s genera, with lists of species, according to the surface-diagnosis. Gray, in his ‘Guide,’ unfortunately copied from H. Adams’s lists without examination. Lastly, Chenu, as usual, reproduced the mis- takes of H. Adams, with fresh ones of his own.
Having had unusual opportunities of dissecting out the valves of Chitons, I have felt compelled to rectify the pre- viously published lists, and also to propose various new genera. These I communicated to Mr. Binney while his edition of Dr. Gould’s ‘ Invertebrata’ was passing through the press ; but he did not think well to alter the position of every one of our species, as I feel compelled to do.
1. The Chiton apiculatus does not appear in H. Adams or Gray. It is a true Chetopleura, distmguished by the thin hairy girdle, regular valves with sharp teeth, and long series of gills. Ihave not seen it alive. It ranges from Southern Massachusetts to Florida. The genus is for the most part tropical.
a
Affinities of the New-England Chitons. 121
2. The Chiton ruber is Leptochiton ruber of H. Adams, and is probably Callochiton puniceus, Couth., of the same author. It is the Tonicia rubra of Gray’s ‘ Guide,’ to which he adds as synonyms, in P. Z. 8., marmorea and fulminata; and it also appears in Gray’s ‘Guide’ as Corephium? rubrum. It has not the characters of any one of these four genera, in which our two best authors have placed it. It belongs to Gray’s genus Ischnochiton (= Lepidopleurus, H. Ad., not Risso), section ft, “mantle-scales minute, granular ;” but as the gill-rows are short, instead of surrounding the foot as in the typical species, it is necessary to establish a fresh genus, Trachydermon. The insertion-plates are, as in [schnochiton and Chetopleura, regularly slit and sharp all round. Mr. Emerton first ob- served a great peculiarity in the animal, that there is a can- cellated space between the posterior gill and the caudal extre- mity. Prof. Verrill observed that in different specimens there were either one, two, or three rows of holes on each side. The caudal lobe is generally figured as an anal tube; but in Z. rubrum it is an imperforate muscle, working the posterior part of the girdle. The feces were distinctly seen to escape, sometimes on one side, sometimes on the other, as it appeared to me from a slit on each side.
3. The Chiton albus is Leptochiton albus of H. Adams,= sagrinatus, Couth. Itwice captured a live specimen ; but each time it eluded the aftersearch. I do not doubt that this is also a Trachydermon, but cannot vouch for the peculiar cha- racters above quoted. The genus belongs to cold and tempe- rate seas.
4, The British C. marginatus is also a Trachydermon, and not a Leptochiton. It is the C. cinereus of Lowe, Forbes, and Hanley, but not of many other writers. Of the unique American shell so called [ can say nothing.
5. The C. marmoreus, common at Eastport and northwards to Greenland, is Tonicia of H. Adams and Gray, simply be- cause the girdle is smooth. ‘The true southern Tonicie, how- ever, have pectinated insertion-plates and ambient gills, like the typical Chitons; while the northern species so called have sharp plates and short gills. They differ, in fact, from Trachydermon simply in the girdle being destitute of the mi- nute scales. I distinguish the group as Tonicella.
6. The C. mendicarius does not appear in the lists, and is probably unknown in Europe. Fortunately a very few speci- mens were dredged in the ‘ Bluelight,’ one of them smashed but very large. It is known outside by the minute bristles on the girdle; but within it presents the very abnormal characters which had before been observed only in the minute British
122 On the Generic Affinities of the New-England Chitons.
C. Hanleyi. This appeared as Leptochiton Hanleyi in Gray’s first paper, but as Acanthopleura Hanleyi in his ‘ Guide,’ p- 183. But in the same book, p. 186, the same species re- appears as HHanleya debilis, the genus (constituted for that species alone) being said to have lateral tufts of spines; in- sertion-plates entire, of terminal valves alike. H. Adams, following this diagnosis externally, described other species which really had these spine-tufts though not the internal characters. However, on examining every specimen of the species in the market, I could not discern a single spine-tuft, though announced by the accurate Lovén. I found, however, excellent internal characters. All the valves were destitute of insertion-plates except the anterior one, which really was ‘entire,’ having one continuous plate, not slit. I did not know whether to believe my own eyes or the testimony of Lovén and Gray, till Prof. Verrill allowed me to open the large, smashed specimen of C. mendicarius. It proved to be a true Hanleva, according to my diagnosis, but not according to Lovén and Gray. I presume that the contraction of the skin in so minute a shell led to the appearance of tufts, and that Dr. Gray supposed that the posterior valve had an entire plate like the anterior. I should be glad of the opinion of the Section whether the genus Hanleia should follow the type against the diagnosis, as here given, or an unreal diagnosis against the type, as followed (in part only) by H. Adams. The animal of this species resembles Leptochiton in haying short posterior gills, and a central anal tube from which the feces were seen to exude.
7. A similar confusion attends the last and most remarkable species, C. Hmersoniz. Several live specimens were dredged by the ‘ Bluelight,’ one of extraordinary size ; and still more have been dredged by Principal Dawson at Murray Bay. For the original species C. vestitus, from Alaska, a genus Amicula was constituted by Gray, characterized by covered valves and re- gular pore-tufts. The elder Sowerby figured the Hmersonii as vestitus in his ‘ Conch. Illustr.’; hence Dr. Gould naturally looked for the pore-tufts, and found them. Having received a fresh specimen from Dr. Stimpson, | could not find them. I wrote to Dr. Gould, who sent me his type specimens, with sketch of regular pore-tufts, as he saw them; but still I could not. He died without clearing the difficulty ; and I presumed there might be two species, one with and one without pores. But after examining both northern and southern suites of spe- cimens, I feel confidence in stating that there are no true pores, but simply a profusion of hair branches, generally very irre- gular, but sometimes, in early stages, more conspicuous at the
Viscount Walden on two new Species of Birds. 123
sutures. I propose, therefore, to keep the name Am7cula for the Alaskan pore-bearing species—and to name this (with the Alaskan Pallasiz) Stimpsoniella, in honour of one of the best naturalists born in New England. In this genus, as in Tra- chydermon, the feeces are expelled through slits close to the caudal lobe, one on each side. When at rest, the creature makes a posterior fold in the girdle, corresponding to the wave in the posterior valve.
I should be extremely indebted to any gentlemen who would lend me unusual Chitons for examination, previously to the publication of my ‘ Contributions towards a Monograph of the Chitonide’ by the Smithsonian Institute. There is also a great field open for investigation to all those who can examine living Chitons or even dissect alcoholic specimens. It is known that the external characters are not coordinate with the internal ones; it remains to be found out whether either of them correlate with the anatomical characters of dentition, gills, vent, &c., which ought to furnish the best divisions in arranging this difficult group.

On Norwegian Hydroida from Deep Water. 125
XVIII.—WNotes on Norwegian Hydroida from Deep Water. By the Rev. Tuomas Hicks, B.A., F.R.S.
A PAPER of remarkable interest has just been published by G. Ossian Sars on the deep-water Hydroida of the Norwegian seas*. The investigations of this excellent observer, who worthily carries on the work of his distinguished father, have established the fact that a very varied Hydroid fauna exists in this region at depths varying from 50 fathoms to 300 fathoms. It comprises no less than fifty-eight species, of which sixteen appear to be new to science. From the tables (showing the distribution of the Norwegian Hydroids both vertically and horizontally) which are appended to the descrip- tive portion of the paper it appears that the most productive region lies between 50 and 100 fathoms. In this zone about two thirds of the whole number of species recorded for Norway have occurred (fifty-four out of eighty-four).
The littoral region, as might be expected, is barren, yielding only six forms—a striking contrast to the corresponding zone on our own shores, which teems with Hydroid life. The Laminarian is hardly more fruitful, giving eleven, of which two are common to it and the preceding. From 10 to 20 fathoms thirteen species have been obtained, from 20 to 50 (the ‘Coralline region’’) forty-two. Below 100 fathoms the numbers diminish with the increase of depth; from 300 fathoms only five species have been procured (Plumularia gracillima, n. sp., Lilellum serpens, Lafoéina tenuis, Campanularia ver- ticillata, and Perigonimus abyssi,n. sp.). The last of these alone passes the 300-fathom limit, and actually reaches 400.
If we except the fragments of a supposed Hydroid, brought up by the dredge of the ‘Porcupine’ from a depth of 2435 fathoms, of which nothing definite is known, the extreme vertical limit of Hydroid distribution would seem to lie between 600 and 700 fathoms, so far as our present knowledge goes. And it must be remarked that below three hundred fathoms a very small number only of forms have been obtained, a few straggling outliers, several of which seem to be much more at home in more moderate depths. In no sense can the Hydroida be considered an abyssal tribe.
In the chapter on “ Distribution in Space” in Allman’s ‘Monograph of the Tubularian Hydroids’ he places the maxi- mum of development in the Coralline zone ; but on the Nor- wegian coast it must be assigned to the “‘ deep-water region ” immediately succeeding it, which yields fifty-four species

against forty-two in the former. And the character of this “deep-water ” fauna is as remarkable as its richness. It in- cludes no less than thirteen of the sixteen undescribed species obtained by Sars, and (probably) three new generic types.
It is interesting to note the extended vertical range which these investigations have established for several well-known species. Thus Tubularia indivisa, which is common between tide-marks on the English coast, has been taken up at a depth of 200 fathoms ; Plumularia setacea, a common denizen of our rock-pools, occurs only between 50 and 100 fathoms in the Nor- wegian seas ; Myriothela, which is found near low-water mark, ranges to 100 fathoms ; Podocoryne carnea is obtained on the shore and from 200 fathoms, and Hydractinia echinata at low- water mark and from 100 fathoms. It is also worthy of remark that Sars has obtained from a depth of 400 fathoms a Hydroid which he refers to Perigonimus, an Athecate genus, producing free reproductive zooids. In all previous cases the species dredged from great depths have been such as are pro- pagated by means of fixed sporosacs and not by planoblasts *.
Passing to the descriptive portion of the paper, the first point of special interest is the occurrence of a small group of Plumularian Hydroids belonging to the genus Aglaophenia. This form is specially characteristic of warmer latitudes. On our own coasts it is comparatively rare in the north and north- eastern districts; in Shetland it is represented by a single species, A. myriophyllum. Still further north it has only oc- curred in the deep-water region, to which dredging has recently been extended. Near Stavanger, off the island of Hvitingsé, Sars has obtained three supposed new species of this fine genus, in depths varying from 80 to 150 fathoms. An ex- amination of this group of southern strangers, thus encountered in the deep northern waters, discloses some points of interest. They were obtained on a muddy bottom at very considerable depths, and, we may therefore suppose, in one of the warm areas to which our attention has been drawn of late f.
The first species described (Aglaophenia radicellata) is
* Vide Allman’s ‘ Monogr. Tubularian Hydroids,’ part ii. p. 165. It is true that Sars did not actually observe the planoblast of his Perigonimus abyssi; but he had the opportunity of examining the gonophores, and had no doubt of the Medusan nature of their contents.
+ This is a mere conjecture, as we have no precise account of the nature of the ground ; but the deep-water region off Hvitingsé appears to possess a rich and peculiar Hydroid fauna which suggests the inference that it enjoys a comparatively high temperature. Allman mentions a new Plu- mularian genus, which was obtained during the cruise of the ‘ Porcupine,’ at a depth of 682 fathoms, in water where the temperature ranged from 30°°5 Fahr. to 29°°8 Fahr. (‘Tubularian Hydroids,’ pt. ii. p. 165).
Hydroida from Deep Water. 127
closely allied to the well-known A. myriophyllum of our own coasts, upon which, indeed, it is a very slight variation. In the shape of the calycles and in the minute structure generally the two are almost identical. The differences lie chiefly in size and habit, the points most readily affected by change of ex- ternal conditions. The northern form is dwarfish as compared with our own ; it looks stunted, and wants the elegant plumose appearance so characteristic of the latter. The stem, too, is simple and slender, instead of being composed, as in the normal A. myriophyllum, of several tubes bound together. One other difference between the two exists: in A. radicellata a large number of long and much-branched fibres are given off from the base of the stem, which form a spreading root-like appen- dage; by this the zoophyte fixes itself in the muddy ground, from which it was obtained. This, however, it must be remembered, is only an exaggerated condition of a structure which exists in A. myriophyllum. The latter zoophyte rises from a tuft of tangled fibres, a mere means of attachment when it grows on solid substances, but which, we can readily suppose, might be developed into a root-like organ under other conditions of life. The corbula of A. radicellata seems to resemble that of A. myriophyllum. The similarity of the two forms in minute structure * is really very striking, and the differences between them are just those which a change of locality might most readily produce.
The second species described by Sars (A. bicuspis) exhibits more distinctive characteristics ; but its calycles are clearly of the myriophyllum type. It is somewhat larger than the pre- ceding, but does not exceed a couple of inches in height. The stem 1s compound towards the base ; and the pinnulated portion is much larger than in A. radicellata. The calycles in shape and arrangement resemble those of the last-named species and of A. myriophyllum ; but the minute crenulation of the rim is wanting, and the central tooth on the front margin, which in A. radicellata was truncate and slightly sinuated at the top, is here divided down the middle so as to form two acuminate processes, which have suggested the name of the species. But the most remarkable peculiarity of A. bicuspis is found in connexion with the gonosome. The reproductive
* Sars seems to consider that the margin of the calycles is more distinctly crenulated in the Norwegian than in the British form; but the difference, if there is any, is of the slightest. Both are crenulated; and the crenations are of precisely the same character. A difference, however,
does exist in the character of the anterior tooth, which in A. myriophyllum is pointed, in the northern form truncate and slightly sinuated at the
apex. 10*
128 Rev. T. Hincks on Norwegian
capsules, instead of being borne, as in A. radicellata, on a certain number of the pinnules which are modified in structure so as to constitute a protective case for them (the corbula), are ranged along one side of the main stem; the usual corbula is absent; but at the base of many of the pinnules a bifid or trifid process is developed, and these processes, ranged in a row on each side close to the stem, bend inwards towards one another and so form a kind of protective co- vering for the gonothece. This structure is unique amongst the known Plumulariide. The processes just described are furnished with many of the sarcothece (or nematophores) so characteristic of the Plumularian family, and closely resemble in structure the elements which compose the corbula. Indeed we may regard them as constituting a kind of corbula, which, however, is developed in the axis of the plume, corresponding with the altered position of the capsules, instead of laterally along the pinnule. A. bicuspis fixes itself upon sponges ; and its fibrous base is merely a flattened disk for attachment.
In the third species (A. integra), which is of larger growth, of a graceful plumose shape, and occasionally branched, we have the very same type of calycle ; but the tooth-like processes on the margin have disappeared as well as the crenulation, and the rim is now perfectly plain. The sarcothece are much the same as in the two preceding forms; the capsules are borne on the central stem, as in the last, but all traces of protective appendages are wanting. The gonosome exhibits the character which we find in A. pennatula and kindred species.
From this deep-water region, then, near Hvitingsé we have three species of Aglaophenia all referable to the myriophyllum type, which are distinguished by very slight differences in the minute structure of the trophosome, but exhibit three distinct modifications of the gonosome. In the one which comes nearest to A. myriophyllum we find the usual open corbula ; in another, a set of appendages developed near the base of the pinne, constituting a kind of axial corbula; in the third we have the gonothece wholly unprotected, as amongst the Sertulariide, and borne on the main stem. The first of these modifications of the gonosome is characteristic of Kirchenpauer’s subgenus Lytocarpia, and the second, I believe, of Allman’s genus Gonocladium (to be described in the report on the ‘ Porcupine’ dredgings). If the genus Aglaophenia is to be dismembered, and the species composing it are to be distributed into groups distinguished by the character of the gonosome, I should pro- pose the name GYMNANGIUM for those with unprotected gonothece.
Sars has also added to the Norwegian list several species of
Hydroida from Deep Water. 129
the genus Plumularia, and a very beautiful new generic form (Polyplumaria) allied to the latter.
Heteropyxis norvegica, i. sp.
Amongst the new Plumulariide we find a form which is referred to the Heteropyxis of Heller. I have given reasons elsewhere * for merging this genus in Plumularia; but I now find that I have misapprehended the characters on which it is based. In his brief generic diagnosis Heller makes no mention of the only peculiarity to which I should be at all disposed to attach any importance; and as I was unacquainted at the time with Meneghini’s description of his Lowenva (which is identical with Heteropyxts), my decision was founded on an imperfect knowledge of the distinctive characters. The real peculiarity of the genus Heteropyxis is the subspiral arrangement of the pinne ; in this it differs from Plumularia and makes an ap- proach to Antennularia. The other characters are insignificant; but it may be convenient to retain the genus for those forms which, without being truly verticillate, have the pinne distri- buted round the stem. The curious point about H. norvegica is that it bears cornucopia-shaped capsules, exactly resembling those of Plumularia cornu-copie (mihi), a species from the Devonshire coast ; the form is remarkable, and it is, as far as I can judge, absolutely identical in both. In H. norvegica, however, the position of the gonothece is peculiar: they are developed in pairs from a distinct process on the lowest joint of the pinna, a little above its point of origin.
Diphasia elegans, n. sp., and Sertularia tenera, n. sp.
These two new Sertularians were obtained from a bottom of soft mud or ooze, in depths ranging from 150 to 200 fathoms, and, we may therefore presume, in a comparatively warm area.
The Diphasia bears a strong general resemblance to D. at- tenuata (mihi). The chief points of difference seem to be the absence of joints on both stem and branches and of the tendril- like prolongations of the latter, the greater distance between the pairs of calycles, and the extraordinary development of the creeping stolon. The latter is the most marked character, and connects itself directly with the nature of the locality in which the species isfound. A luxuriantly developed, much ramified, and sinuous fibre spreads over the muddy sea-bottom, through a great part of its length perfectly free, and only attached here and there to the small fragments of stone or shell sparingly

scattered about in the neighbourhood. From this, at very con- siderable intervals, rise the slender plumose shoots.
The Sertularta, which is of a dwarf and meagre habit, is also distinguished by the largely developed stolon, which creeps unattached over the mud. It is interesting to remark the modification of this portion of the structure in conformity with the nature of the base on which the zoophyte grows. One of the Aglaopheniw and two of the Sertularie obtained by Sars from great depths have thus adapted themselves to the peculiar conditions of ooze life.
Ophiodes parasitica, G. O. Sars (a. sp.).
Perhaps the most interesting of the many interesting forms for a knowledge of which we are indebted to the energetic researches of the Norwegian naturalist, is the remarkable Hydroid which he has named Ophiodes parasitica. In general appearance and structure it closely resembles a Plumularia, and might pass on a slight inspection for a stemless variety of one of the smaller kinds. But, instead of the ordinary sar- cothece characteristic of the Plumularian family, it is furnished with the curious snake-like appendages which distinguish the genus Ophiodes (mihi). Judging from Sars’s description and figures, there is no appreciable difference between these organs as they occur in the Norwegian species and on the British Ophiodes mirabilis. Yn each case they consist of a slender and highly extensile tentaculoid body, protected at the base by a small chitinous cup, and terminated at the free extremity by a globose capitulum filled with thread-cells. In O. para- sitica they are confined to the erect stems, and are not present, as in O. mirabilis, on the creeping stolon also; one of them is generally placed a short distance below the calycle; and sometimes there is another alittle above it. But though there is this remarkable point of agreement between the Norwegian Hydroid and the British, they are plainly not referable to the same genus. The affinities of O. parasitica are with the Plumulariide ; those of O. mirabilis are as clearly with the Haleciide. Probably the two families are closely related ; in the forms now under consideration they seem to make a near approach to one another. Ophiodes mirabilis differs in some important particulars from the ordinary type of Halecium ; and the points im which it thus differs approximate it to such a form as the O. parasitica of Sars. The large polypites, which cannot retract themselves within the calycle, are common to all the Haleciide and to the genus Plumularia; and we
now know that organs akin to the sarcothecze are found in both the families.
a
Hydroida from Deep Water. 131
As a new genus must be constituted for the Norwegian Hydroid, I propose for it the name Ophionema*. It may be defined as follows :—
Suborder THECAPHORA. Family Plumulariide.
OPHIONEMA, n. gen.
Generic character.—Shoots small, simple or slightly branched, jointed, not regularly pinnate or plumose, attached by a creeping stolon; hydrothecz sessile, unilateral, cup-shaped ; tentaculoid organs distributed singly on the shoots, exten- sile, filiform, terminating above in a globular capitulum filled with thread-cells, and protected at the base by a chitinous cup; gonothece of large size, borne singly near the base of the shoots; polypites not retractile within the calycles T.
Ophionema parasiticum, G. O. Sars (sp. unic.).
Halecium gorgonoide, G. O,. Sars (n. sp.).
This is another of the specially interesting forms brought to light by the exploration of the deeper regions of the sea- bottom. In most of its characters it bears a perfect re- emblance to the well-known Halectum; but it differs from Sn being furnished with a peculiar tentaculoid organ, some- what similar to that which occurs on Ophiodes and on the new genus Ophionema, which I have constituted in this paper. ‘These curious appendages are minute offshoots from the ccenosare, which pass outwards through a simple orifice in the polypary, and project beyond it as naked, extensile, tentaculoid processes of a somewhat clavate figure, terminating above in a rounded capitulum filled with thread-cells. They differ from the similar structure which occurs on Ophiodes in the total absence of the chitinous covering at the base, and in the less distinctly capitate form of the free extremity. These appendages are distributed in great numbers over the stem and branches; and one of them is almost always present in the immediate neighbourhood of the calycles. There can be no doubt, I think, that they constitute a cha- racter of generic value, and that the present species must be detached from Halecium. I propose to name the new genus

that must be formed for its reception Hydrodendron ; it may be characterized as follows :—
Suborder THECAPHORA. Family Haleciide. Hydrodendron, n. gen.
Generic character.—Zoophyte plant-like, much branched, rooted by a creeping stolon; hydrothece biserial, tubular, jointed to a short lateral process from the stem; polypites very large, partially retractile; tentaculoid appendages minute, filiform, naked, terminating above in a subglobose
capituluin filled with thread-cells, distributed over the stem and branches, one below each calycle ; gonothecee unknown.
Hydrodendron gorgonoide, G. O. Sars (sp. unic.).
The polypites of this interesting form are remarkably large, furnished with about twenty-four tentacles, and of a bright yellow colour. The compound stem is thick and rugged and nregularly branched, and when covered with its conspicuous coloured polypites, the species bears, as Sars has remarked, a striking resemblance to a Gorgonda. It is peculiarly tree-like in appearance, and fully entitled to the generic name which I have given it. It has many characteristic features; but of course its principal distinction is to be found in the curious appendages to which I have referred.
Lafoéa fruticosa, M. Sars.
Amongst the Lafoéide included in Sars’s catalogue of Nor- wegian species is the L. fruticosa, M. Sars, which was de- scribed many years since by his father in his ‘ Zoologisk Reise i Lofoten og Finmarken.’ This form I have identified with the L. gracillima, Alder*; and in doing so I had the concur- rence of Mr. Alder himself, who believed that his species was identical with the Norwegian, and that his name must yield to the earlier designation conferred by Sars. Mr. G. O. Sars, however, thinks that I have decided wrongly ; he figures what he supposes to be his father’s species, and holds that it is certainly distinct from ZL. gracillima. In this, I have no doubt, he is right; I have as little doubt that his figure does not represent L. fruticosa, but another and very different species. It is, in fact, referable to the form which I have else- where described as Lafoéa grandis.
* ‘History of British Hydroid Zoophytes,’ i. p. 202.

Hydroida from Deep Water. 133
A reference to M. Sars’s more detailed description of his L. fruticosa, in his paper “ Bemerkninger over fire Norske Hydroider”’ (1862), will show that it is very different from the form which his son has now figured. The latter has a regular, campanulate calycle of considerable breadth; the calycle of the former is described as bearing a general resem- blance to that of L. dumosa, and as being slightly bent, with the convex side of the curve turned upwards, or occasionally reversed. In short, it is represented as being tubular and bent, whereas the hydrotheca in G. O. Sars’s figure is campanulate and straight. 'The only differences which Prof. Sars could detect between his species and Alder’s were that in the latter the ca- lycle was rather more slender than in the northern form, and the pedicle “ loosely twisted” instead of being distinctly ringed. But Alder’s LZ. gracillima has a long, narrow, tubular calycle, totally unlike that which the younger Sars has figured in his paper. I have, however, other and very conclusive evidence that the L. fruticosa is not what the last-named naturalist supposes it to be. Prof. Sars and Mr. Alder corresponded about their species and exchanged specimens; and I have in my possession a bottle sent me by the latter, and labelled by him, containing Norwegian examples of L. fruticosa, which he had received from its discoverer. From these specimens the figures (Plate VI. figs. 8-10) accompanying my paper on Icelandic Hydroids in the present number were drawn (with the camera lucida) ; beside them [ have placed a pair of calycles (Plate VI. figs. 6, 7) from specimens of L. gracillima dredged at Oban. ‘The close similarity between the two is at once apparent; the form may be said to be identical in both; and the only difference between them to which I should be dis- posed to attach the slightest significance is found in the cha- racter of the pedicle. In the British form it is merely twisted into two or three imperfect whorls; in the northern it is com- posed of three or four rings. Sometimes they are almost obsolete (Plate VI. figs. 9, 10) ; but traces of them may always be detected. I confess I cannot regard this trifling variation as a specific distinction, and must therefore continue to rank the L. gracillima of Alder as a synonym of the older L. fru- ticosa of Sars.
I may add that, in his account of the latter species, Prof. Sars has remarked on the thinness and delicacy of the mate- rial composing the calycles, and tells us that when dried they collapse and shrivel up. The same holds good of L. gracit- lima; but in the case of Lafoéa grandis (to which | refer G. U. Sars’s figures) the walls of the hydrothecz are of very stout material, and retain their form in dried specimens.
134 Rey. T. Hincks on Norwegian
Calycella producta, G. O. Sars (n. sp.).
The species described under this name will probably prove to belong to the genus Lovénella (mihi). Its position cannot, of course, be absolutely determined until the history of its reproduction is known; but it closely resembles the L. clausa (Lovén), and is very unlike any known member of the genus Calycella. Its polypite too (so far as the figure affords the means of judging) is of a totally different type from that of Calycella; so that if the characters of its gonosome should separate it from Lovénella, it must still be referred to some other genus. Lovénella is propagated by means of medusiform planoblasts.
The present species differs from the British LZ. clausa principally in the comparative shortness of the conical oper- culum, and the absence of all annulation or crenation on the stem, except at the very base.
Lafoéina tenuis, M. Sars.
This remarkable Hydroid was first described by Prof. M. Sars in 1868*; but we have now a further account of it and an excellent figure from his son. Bearing a curiously close resemblance in its general character to Cuspidella humilis (mihi), it is distinguished from the latter form by the extra- ordinary appendages, allied in structure and function to the sarcothece of the Plumularians, with which it is furnished. These are distributed in great numbers along the creeping stolon, amongst the calycles; they consist of a filiform offshoot from the ectoderm, somewhat enlarged at the upper extremity and invested by a thin chitinous covering.
In the capitular portion are lodged a few large thread-cells ; and immediately above it there is a circular orifice in the chitinous envelope, through which the long barbed threads are discharged. These appendages not unfrequently almost equal the calycles in height, and largely exceed them in number. They remind us of the tubular sarcothece of the genus Aglaophenia, though it does not appear that the sar- costyle has the power of emitting amceboid processes. They may be regarded as an intermediate form between the Plumu- larian sarcotheca and the tentaculoid organ of Ophiodes and Ophionema.
I have lately ascertained that specimens of a Hydroid from Shetland and from the Northumberland coast, which I formerly referred to Cuspidella humilis, really belong to the present
* “ Fortsatte Bidr. til Kundskaben om Dyrelivets Udbredning i Hayets Dybder,” Vid. Selsk. Forh. f. 1868 (Christiania).
Hydroida from Deep Water. 135
species, so that Lafoéina tenuis must take its place in our fauna. At the time I noticed the transparent clavate processes associated with the calycles, but supposed them to be some parasitic growth.
A question may arise whether Cuspidella humilis is a distinct form at all, or whether it has been founded on ex- amples of Lafoéina. I have been able to settle this point conclusively by a reference to specimens of the former; and Sars, who is intimately acquainted with the latter Hydroid, includes Cuspidella humilis also in his list of Norwegian species, and therefore recognizes them as distinct.
I have carefully re-examined the other species of Cusp7- della (C. grandis and C. costata), and find them to be un- doubtedly destitute of the appendages.
Gonothyrea hyalina, Hincks.
This fine species I have referred provisionally to Gono- thyrea*, having only had the opportunity of examining im- mature gonophores on specimens preserved in spirit. Sars, however, has obtained it at Lofoten with fully developed gonophores exhibiting the characteristic structure of this genus, and has thus definitely settled its systematic position.
Acaulis primarius, Stimpson.
We have hitherto known this interesting Hydroid im- perfectly, through the description of it given by Stimpson in his ‘ Marine Invertebrata of Grand Manan.’ Sars, however, has obtained it in deep water (40-100 fathoms) off the Norwe- gian coast on muddy ground, and has thoroughly investigated its structure.
The two most important points which he has determined are the mode of its attachment and the history of its reproduction. Stimpson found his specimen floating in the open sea, and describes Acaulis as permanently free. It appears, however (as Allman had conjectured) that this is an error ; the stalk-like por- tion of the body below the aboral wreath of tentacles is invested by an exceedingly thin hyaline skin, which passes far beyond its free conical extremity in the form of a perfectly transparent sheath, and towards the base is thickly covered with small grains of sand and fragments of mud. By means of this sheath the polypite no doubt roots itself in the sand or ooze, as Corymorpha seems to do by the help of a very similar structure. The reproductive bodies are simple fixed sporosacs, developed in great number immediately above the proximal

tentacles and amongst the capitate arms which thickly cover the whole of the upper portion of the body. Acaulis is closely related to the Tubulariide (through Corymorpha) and the Pennariidx, but seems entitled to stand as the type of a separate family. Myriothela, on the contrary, I should connect more immediately with the Corynide ; and the present species, as Sars has suggested, may be regarded as an intermediate form between it and Corymorpha.
Myriothela phrygia, Fabricius.
The British species of the genus Myriothela has hitherto been identified with the MW. arctica, M. Sars, and the earlier Lucernarta phrygia of Fabricius ; and the specific name con- ferred by the latter author has taken its place in our nomen- clature. It appears, however, according to Mr. G. O. Sars, that two distinct forms exist, both of which occur in the Norwegian waters, and that the one which has been observed on our coasts differs from that which Fabricius first discovered and Prof. M. Sars afterwards so well described. It becomes necessary, therefore, to revert to the earliest name conferred on the British species, which we owe to Vigurs (1849). It will stand hereafter as MW. Cocksii, while the original species must retain the name of phrygia.
It is to be regretted that Sars has not given us a fuller description of the northern form, and indicated more precisely the points in which it differs from the British. He tells us generally that it is distinguished from it by its different mode of attachment, and that its gonophores are borne on more or less branched processes furnished with capitate tentacles, resembling those which are scattered over the body.
Syncoryne eximia, Allman.
To this species, an inhabitant of the Laminarian zone on our English coasts, Sars refers a Syncoryne taken at Bodé in 80-100 fathoms. Judging, however, from his brief account, his identification seems to me more -than doubtful. He de- scribes his species as having a peculiarly dark brown polypary, which is most obscurely ringed; the polypites have very few tentacles. S. exi’mia, on the contrary, has a transparent, light-coloured polypary, and its polypites are furnished with as many as from twenty to thirty tentacles. The annulation is very distinct so far as it goes, bemg confined, however, to the very base of the principal stems, and to certain portions of the branches. It will be found, I believe, that the Nor-

XIX.—On a new Species of Fruit-Pigeon from Northern Queensland. By Joun GOULD, F.R.S. &e.
Tuts little pigeon, which I propose to call Lamprotreron porphy- rostictus, is totally distinct from its ally, the L. superbus, from the same part of Australia. ‘The most conspicuous character of this bird is the purplish-blue spot at the back of the head ; hence its specific appellation porphyrostictus.
The throat is grey, and the abdomen crossed with two in- distinct bars of yellowish white ; this latter colour also pervades all the outer edges of the under tail-coverts ; with the excep- tion of the two middle ones, all the tail-feathers are obscurely tipped with greyish white; the secondaries and the larger wing-coverts are edged with yellow; feet bright orange ; tarsi thickly clothed with green feathers ; bill dark.
The young of the year, having nearly attained its full size, differs from the adult in the total absence of the purple spot at the back of the head, and in having the lesser and greater wing-coverts fringed with yellow.
Total length 7 inches, bill 2, wing 43, tail 22, tarsi 3.
The two specimens of this species I possess were obtained at Cape York; and J need scarcely say that before describing this bird I have compared it with all the species in our national collections, brought home by Mr. Wallace from the Papuan group of islands, and I find it quite distinct from each of them.

XX.—WNotes on some Fishes obtained at considerable Depths in the North Atlantic. By Dr. ALBERT GUNTHER, F.R.S.
ProressoR WYVILLE THOMSON, before his departure with the ‘Challenger’ expedition, kindly placed in my hands for examination some fishes which had been obtained at consider- able depths during the cruise of H.M.S. ‘ Porcupine’ in the year 1869. In the first imstance they had been sent for determination to the late Mr. Couch of Polperro, who affixed labels with names to the bottles; but no descriptions of the species were published by him; so that I should have omitted to allude to his nomenclature (which cannot be adopted), if I had not been informed that the fishes were enumerated under those names in one of the ‘ Porcupine’ reports.
Small as the collection is, itis of interest in two respects :-—
1. Inasmuch as it offers additional evidence that fishes hitherto known from more southern latitudes occur in the North Atlantic at a moderate depth (of between 80 and 200 fathoms) *.
2. Inasmuch as the fishes from the depth indicated do not yet show the well-known characteristics of deep-sea fishes developed in any degree. Therefore fishes like Plagyodus, Melanocetus, Saccopharynx, Regalecus, Chiasmodus, &c. must inhabit a much deeper horizontal zone (from 300 to 800 fathoms), as, indeed, has been supposed and affirmed for many
ears. ‘ The jist bottle is marked “ No. 17. (18.6. 69). 54. 10 N. 10.59 W. 183 fms., muddy sand.” Mr. Couch intended to describe the specimen contained in it as ‘“‘Macrourus linearis.”
This fish, which is not in good condition, crabs having eaten holes into various parts of the body, proves to be Gadiculus ar- genteus, described by Guichenot in ‘Explor.Algér., Poiss.’ 1850, p- 101, pl. vi. fig. 2, from specimens obtained at Algiers. Iam not aware that the species has been noticed since ; and therefore it is a point of interest to meet with it again in the North Atlantic. There is nothing whatever to indicate an affinity to Macrourus; indeed Gadiculus proves to be a Gadus slightly modified for living at a greater depth. Even the vomerine teeth, by the alleged absence of which, according to Guichenot, the genus was technically distinguished from Gadus, are present ; but the scales, which are deciduous, and lost in our specimen, are larger than in the allied species of Gadus. The formula of the fin-rays is D. 9 or 10 | 13 | 18. A. 17 | 16.

considerable Depths in the North Atlantic. 139
A second bottle (labelled ‘‘ H.M.S. ‘ Porcupine,’ between Shetland and Faroe, 200 faths. 1869,” and determined by Mr. Couch as “Macrourus, sp. n.”) contains an example, about 10 inches long, of Coryphenoides norvegicus. It agrees very well with Sundevall’s excellent description published in 1840, which I can supplement by giving the number of dorsal rays as about 190, the tail of the specimen being perfect. There are eight or nine series of scales between the first dorsal and lateral line—and not four or five, as stated in the diagnosis of the ‘Catal. Fish.’ iv. p. 396, in accordance with Gaimard’s figure of this species. Another, smaller specimen of the same species was in the third bottle, and stated to be from a depth of 540 fathoms. The writing on the label originally placed on the third bottle has entirely faded and is illegible; but we are informed by a second label in Mr. Couch’s handwriting that the bottle con- tains a “‘Kurtus and Macrourus, both new. 1869. 540 fathoms.” The latter specimen has been noticed above. The former, of course, is widely different from the Indian genus to which Mr. Couch referred it, and is, in fact, Argyropelecus hemigymnus, a species common in the Mediterranean and neighbouring parts of the Atlantic. A small fourth bottle contains only one specimen; it is labelled, in Mr. Couch’s handwriting, ‘‘ Ophidium—eel-like, deep sea—1869. H.M.S. ‘Porcupine.’ 180 faths.” This spe- cimen is the young of Anguilla Kienert, a species hitherto known from the Mediterranean only. The fifth bottle (labelled “ H.M.S. ‘ Porcupine.’ Between Shetland and Faroe. 180 faths. 1869’’) contains four speci- mens, named by Mr. Couch Macrourus linearis, C., Blennius fasciatus, C., Gobius Jeffreysit, Callionymus sagitta, C.,
and which I have determined as Motella macrophthalma, Gthr., Blenniops Ascanii, Walbaum, Gobius Jeffreysti, Gthr., Liparis vulgaris, Elem.
It was evidently by a slip of the pen that Mr. Couch applied the name ‘“‘Macrourus linearis” again to a very different fish, viz. Motella macrophthalma, a species which, together with Gobius Jeffreysti, was described and figured by me in this Journal, 1867, xx. p. 290.

XXI1.—On the Invertebrate Marine Fauna and Fishes of St. Andrews. By W. C. M‘Intosu, M.D. &ec.
INTRODUCTION.
THE beach at St. Andrews combines smooth sandy flats with tide-worn ridges of rocks which freely communicate with the German Ocean ; and the proximity to rich coralline ground renders the products of its storms peculiarly varied. An unbroken surface of pure sand extends from the estuary of the Tay past that of the Eden to the north-western border of the city. From this point the rocks run eastward in parallel rows—narrow sandy flats intervening between some of the ridges, which, with one exception, are all covered at high water. Lines of rocks having a similar arrangement fringe the Castle and Pier to the east sands; then a coarse sandy and gravelly beach extends in a southerly direction about half a mile, after which the jagged rocky border passes round the eastern coast to the Frith of Forth.
The greater part of the sandy bay has a depth of less than 10 fathoms ; for at this point the 20-fathom line bends outwards to the Bell rock. The whole region is thus comparatively shallow, and in contrast with that to the north of Arbroath Road, or with the Frith of Forth and the neighbouring coast on the south.
If the fine stretch of sand from the river Eden to the city (usually termed the West Sands in contradistinction to the Kast Sands) which extends to the harbour southward is only en- livened in summer by thousands of bleached heart urchins, broken shells, skeletons of plaice, frogfish, and haddock, or in autumn by the jellies of the medusz, the storms of winter and spring wholly alter the aspect. Immense banks of sea- weeds mingled with black fragments of wood, coal, and muddy matter cover the beach, which in many parts becomes brilliantly phosphorescent at night from the zoophytes and annelids on the blades of the tangles. Amidst this débris are vast numbers of sponges, zoophytes, shells, starfishes, annelids, crabs, and fishes which have been swept from their various habitats. All storms are not equally prolific; they also vary in regard to the abundance of the several groups—a feature probably due to the direction of the wind and the invasion of particular sites. The waste of marine life in such storms does not attract much notice; yet it is extraordinary and so constant that it may be regarded to some extent as a check upon its uninterrupted development. It is, however, to be remembered that even the autumnal ripple in the Outer Hebrides brings
Marine Fauna and Fishes of St. Andrews. 141
countless swarms of Salpe, Velelle, Meduse, and other forms to die on the beach.
The tidal rocks, again, which are mostly covered by sea- weeds, present a varied and prolific site for many species. The rock-pools are both frequent and picturesque; and they possess many undisturbed stones, often of large size, the under surfaces of which are most favourable for the growth and shelter of numerous forms—though of course they cannot be compared in this respect with the littoral stones at Herm, which have a profusion of rare crabs, annelids, ormers and other mollusks, polyzoa, hydroids, and the yellow, red, purple, green, and white sponges. The soft sandstone and shale afford an ample field for the perforations of Pholas crispata, Saxicava rugosa, and Leucodore ciliata. ‘The fissures and chinks of the rocks, moreover, as on almost every part of the British shores, give shelter to a large number, especially the annelids, which find in the muddy or sandy crevices a safe retreat for their soft bodies, slender tubes, or muddy tunnels, and opportunities for capturing sufficient food at the free margin of the rock or from the ingoing currents. It is chiefly in such localities that Sipunculus Johnstoni and swarms of Leucodore and Nicomache occur, while Nereds cultrifera, Eulalia, Syllis, and the nemer- teans are also common. Occasionally an Jdotea is met with ; but the general absence of the isopods in these crevices dis- tinguishes them from those in the gneiss of the south and west, as in the Channel Islands and the Outer Hebrides— and especially from the former by the absence of Pilumnus hirtellus, Arca, the Sabellide, the Hunicide and their allies. To these fissures certain boring annelids and Saxicava chiefly retreat when the rocks do not afford a suitable medium for their perforations—though at St. Andrews there is free scope in this respect, from the sandstones and shales so soft as to be pitted deeply by the common limpet to those nearly as dense as granite.
The sea-margin at St. Andrews, like other parts of the east coast of Scotland, presents decided differences when contrasted with the northern, southern, and western shores, though many forms are common to all. Thus the laminarian zone at St. Andrews is much less luxuriant than that of the Zetlandic waters with the fine forests of gigantic tangles, amidst which there is a galaxy of animal life. The vegetation of its littoral zone is surpassed by the rich Fuci of the tidal rocks and the trailing masses of Chorda filum on the surtace of the sea immediately beyond low-water mark in the Outer Hebrides. Its marine forms are placed under very different circumstances from those in the quiet voes of West Shetland,

as at Cliff Sound and between the Burras, where the still sea- water is bridged by a single arch of a few feet. ‘To represent the Zostera-fields of the west and south there are but a few Conferve, Ulve, and Porphyre attached to stones on the flat surfaces of the beach. The calcareous rocks of the south, and the multitudes of worm-eaten boulders scattered on many parts of the shore, as in the Isle of Wight, form likewise a boldly marked contrast.
Within reach of the modern tide, also, it is interesting to find the remains of oceanic animals long since extinct—to see Actinia mesembryanthemum attached to a mass of encrinite stalks, Litorina rudis in groups on Lingula-shale, and the white coils of Sprrorbis incrusting a nodule containing a fossil fish. Yet these features do not appear much out of place near a city whose pier is to a considerable extent con- structed of the fine old stones and ancient oak which once formed part of the splendid pile of its cathedral.
On the whole the zoological features of St. Andrews are northern.
Subkingdom PROTOZOA. Class RHIZOPODA.
Order Spongiade.
The Sponges of St. Andrews are, perhaps, the least-inves- tigated group, partly because a collection carefully made many years ago has been lost. In looking over those obtained since, Dr. Bowerbank has most kindly given his experienced aid in doubtful cases ; and the description of the new species is solely his. The littoral forms are scattered in considerable profusion between tide-marks under ledges and stones, sometimes near high-water mark. Indeed, in the higher pools and tide-runs in the latter region they are often peculiarly luxuriant. The brightly coloured Halisarca, so abundant on the under surfaces ot stones in the Hebrides, and the rarer botryoidal Tethea are unknown at St. Andrews, as are likewise the cup and turnip sponges of the Zetlandic seas. The greater luxuriance of the ubiquitous Halichondria panicea on the stems of the Lami- narie further characterizes the coast of the extreme west ; and the decay of the seaweed often leaves tubes of sponge from a foot to eighteen inches in length. In like manner the greatly increased size of Grantia ciliata, the vast abundance of Hymeniacidon celata, its beautiful arborescent patterns in the tide-worn shells, and its perforations in the limestone rocks are diagnostic of the warmer waters of the southern coast.
Marine Fauna and Fishes of St. Andrews. 143
The classification of Dr. Bowerbank in his valuable work pub- lished by the Ray Society has been that followed in the list.
Suborder I. CALCAREA.
Grantia compressa, Fabr.; Bowerb. Brit. Spong. ii. p. 17.
Abundant on Cynthia grossularia under shelving rocks be- tween tide-marks, and attached to the roots of Fuci and other seaweeds. It occasionally assumes an abnormal form, and has a broad attached surface under stones. Longest, 3 inches.
Grantia ciliata, Fabry. ; Bowerb. vol. ii. p. 19.
Not unfrequent on laminarian roots cast on the west sands after storms, and growing near low-water mark at the East Rocks. The species somewhat resembles a grain of oat re- moved from its husk,
Leucosolenia botryoides, Ellis & Sol. ; Bowerb. vol. ii. p. 28.
Abundant on the under surfaces of stones in tidal pools, especially if large and little-disturbed. It frequently accom- panies Grantia compressa.
Leuconia nivea, Grant; Bowerb. vol. ii. p. 36.
Found abundantly in the deeper tidal pools, under large stones which have been long untouched. It covers spaces several inches square ; and its margin is generally rounded and “finished” like the border of a lichen. Most of the speci- mens have their surfaces elevated into firm ruge, resembling miniature mountain-ranges, some of the crests rising into flattened lobes ? inch in height. There are at least two varieties of this sponge—the first of which, besides the equi- angular triradiate spicula of the skeleton, the minute acerate ones of the interstitial and dermal membranes, and the uni- eurvo-cruciform, has many spined acuate spicula of consider- able dimensions and others of the same size approaching the fusiformi-spinulate character. In the other variety the latter kinds are so little developed, if present, as not to be dis- tinguished from the ordinary minute acerate forms. In both, almost all the latter are distinctly spined.
Suborder II. S1iicna.
Hymeniacidon ficus, Esper ; Bowerb. vol. i. p. 206. Occasionally from deep water, attached to dead shells. Cla- vate specimens frequently grow from the smaller end of Den- talium entalis. "This species seems to frequent gi ground. 1
144 Dr. W. C. M‘Intosh on the Invertebrate
Hymeniacidon celata, Grant; Bowerb. vol. i. p. 212.
Abundant in shells from deep water, between the layers of which it tunnels its devious tracks. ‘This is one of the main agents in causing the disintegration of dead shells.
Halichondria panicea, Pallas; Bowerb. vol. 1. p. 229.
Scarcely a stone can be lifted near low-water mark, amongst the rocks, but has a patch of this common sponge. Under the cavernous ledges overhanging rock-pools it spreads its structure over the dark red Cynthia, matting together sea- weeds and corallines, and hanging in pendulous nodules on interwoven stalks of Corallina officinalis and Fuci. Near the Maiden Rock splendid specimens are found incrusting a square foot or two of rock in some of the quiet pools. It also abounds on the backs of crabs, such as Hyas araneus and Inachus dorynchus, covering the former so completely that it can scarcely be recognized except by its legs ; and besides the pro- minent oscula of the sponge, on this complex back are gaps for Balani, shells, and seaweeds. On the carapace of the latter species it forms a thinner coating, but is likewise grouped in little nodules on the legs. A mass as large as a good-sized apple surrounds the stem of Chalina oculata; and it is a com- mon envelopment of various stones, mollusks, seaweeds, and tangle-roots. The usual colours of the sponge are yellow, brown, purple, green, and grey. In the interstices of the masses thrown on shore at the West Sands are to be found mul- titudes of marine animals, besides incorporated shells ; and the fine patches at the East Rocks are favourite feeding-grounds of Doris tuberculata. The forms of the spicula of this species are variable, some being much curved like a stretched bow, a few more or less ineequiacerate vermiculoid, besides, of course, the ordinary diagnostic spicula. The odour emitted on tearing it from the rock is characteristic, but causes no sneezing.
Halichondria, n. s.*
The following is Dr. Bowerbank’s description :—“ Sponge coating, thin. Surface smooth and even. Oscula more or less elevated, dispersed, margins thin. Pores inconspicuous. Dermal membrane aspiculous. Skeleton very irregular, rete mostly unispiculous, occasionally bi- or trispiculous ; spicula acerate, short and stout. Interstitial membranes aspiculous.
“Colour in the dried state light nut-brown. Examined in the living and dried states.
“The nearest alliance with the known species of the first
* Dr. Bowerbank has courteously named this species H. M‘Intoshii, Bowerb.
*
Marine Fauna and Fishes of St. Andrews. 145
section of our British Halichondrie is with H. regularis. The spicula of the two species are as nearly alike in size and pro- portions as possible; but this is their only approximation to each other. In their other characters they differ to a con- siderable extent. The colour of H. regularis in the dried state is milk-white ; that of H. M‘Intoshii is nut-brown. An- other important difference is, that while the skeleton of ZH. regularis is remarkable for its symmetry, that of H. M‘Intoshit is regular to a very considerable degree.”
This form is not uncommon on the under surface of stones in tide-runs and somewhat muddy pools not far from high- water mark at the East Rocks. Its greyish brown colour, smooth surface, and prominent, well-defined oscula distinguish it at first sight from its allies.
Halichondria incrustans, Esper; Bowerb. vol. i. p. 249.
Occasionally found under stones near low-water mark, especially at the East Rocks. It forms a thickish crust; and the spicula very much resemble one of the knobbed walking- sticks which taper from above downwards.
Suborder III. Krrarosa. Chalina oculata, Pallas; Bowerb. vol. ii. p. 361.
Thrown in great profusion on the West Sands after storms ; and small specimens are also found under the ledges of rocks near low-water mark. ‘The shape of the specimens varies much: some are flattened and much divided into branches of various sizes, either narrow or broad; others have their branches much matted together so as to form a connected and somewhat coarse “ gorgonian”’ appearance, more or less sepa- rated at the tip. In some the branches arise mostly from one side of an unbroken prolongation of the sponge-tissue. One grows on a valve of Mytilus modiolus, and has a mass of Halichondria panicea round a branch at its base. Another envelops the stem and branches of Delesserta sanguinea, the leaves of which appear here and there from the centre of the sponge. Many are attached to small rolled stones. Those from the beach are loaded with sand, spines of the common and purple heart urchins, bristles of the sea-mouse ; and many starfishes seek refuge in their interstices.
Chalina limbata, Bowerb.; vol. i. p. 373.
Not uncommon on the under surfaces of stones in tidal pools, either coating the surface of the stone or attached to the stems of Corallina officinalis.

XXII.— On Deep-water Hydroida from Iceland. By the Rev. Tuomas Hrincxs, B.A., F.R.S.
[Plates VI., VII., & VIII.]
Some years have elapsed since Mr. Busk placed in my hands a bottle containing some northern Hydroida and Polyzoa which had been obtained by Dr. Wallich. The contents have been long since partially examined, and some of the results have been already published ; but no separate report upon them has appeared, and some new forms which they have yielded are still undescribed. JI propose therefore in the present paper to deal with the Hydroid portion. The gathering, though a very small one, is characteristic and interesting. It was taken up from a depth of 100 fathoms off Reikiavig, Iceland, ‘‘ amongst icebergs, grounded and drifting.” ‘The number of species observed is only seventeen; and of these a large proportion belong to the Campanularian group of the Lafoéide. The extreme north seems to be in a special manner the home of the minute forms composing this family. No less than twelve species have been obtained off the coast of Norway by Dr. M. Sars and his son G. Ossian Sars, whose name is so honourably connected with the early history of «deep-sea dredging. ‘To these must be added four more, which I have found amongst the Icelandic dredgings, raising the whole number of Lafoéidee known to inhabit the northern seas to sixteen. The British species number eleven.
These Hydroids are mostly inhabitants of deep water; off the coasts of Norway many of them occur at depths of from 50 to 100 fathoms, others at depths of 150, 200, and 300 fathoms respectively. ‘The Icelandic specimens, as I have mentioned, were taken up in 100 fathoms*. A few of the Nor- weglan species occur in shallower water, ranging from 20 to 50 fathoms ; but they constitute a very small proportion of the whole number. Some have a wide bathymetrical range: thus Lafoéa dumosa occurs in the littoral or Laminarian region, and has been dredged in 145 fathoms; and L. gracillima, which I have obtained in great luxuriance at Oban in 15-20 fathoms, has occurred to G. O. Sars off the island of Hvitingsé in 150. F%lellum serpens, the common parasite of some of the larger Sertularians in the “Coralline zone,” ranges, according
* During the ‘Porcupine’ expedition a Lafoéa was dredged up from a depth of 545 fathoms. It was obtained from the “cold area” between Shetland and the Faroe Islands, at a point where the temperature of the water varied from 30°°5 Fahy. to 29°°8 Fahr, (vide Allman’s ‘ Tubularian Hydroids,’ part ii. p. 165).
Hydroida from Iceland. 147
to the same excellent observer, to the great depth of 300 fathoms. On the whole, the Lafoéide may be regarded as a deep-water group, and as most richly developed in the northern seas, so far as our present knowledge goes.
In the Icelandic dredgings they occur in profusion, and most of them attain a remarkable size. In the present paper I shall describe a new species (Lafoéa grandis) which is a veritable giant amongst its pigmy kindred, its calycles being nearly three times as large as those of the well-known L. dumosa. The representatives of Calycella syringa are about twice as large as those which may be met with on our own coasts. Calycella pygmea * as found amongst the icebergs has almost ceased to deserve itsname. I may also mention that Labrador specimens of Lafoéa pocillum are about twice the size of others obtained at Oban. And the larger growth is not confined to the Lafoéide ; a gigantic variety of Sertularella polyzonias is also present, the calycles of which are very nearly three times as ample as those of the normal form, while the whole habit is singularly robust. Sertularella tricuspidata, a distinctly north- ern form and the principal element of the Icelandic dredgings, exhibits the greatest luxuriance and beauty, and bears in amazing profusion the reproductive capsules, which frequently line the branches throughout their whole extent.
What may be the cause of this unusual development [ cannot pretend, with my present information, to decide ; but
he fact is undoubted.
The following is a list of the species ;—
Subkingdom CQfLENTERATA. Class HY DROZOA.
Order HyDROIDA. Suborder THECARHORA. Family Campanulariide. Campanularia volubilis, Linn. Abundant on Sertularia &c. With capsules. * In my ‘History of the British Hydroid Zoophytes’ I have ranked this species doubtfully amongst the unoperculated forms which constitute
the genus Lafoéa. But 1 have ascertained that it is in fact provided with an operculum ; and it must therefore be transferred to the genus Calycella.

Family Lafoéide.

Stem erect, compound, much and irregularly branched. Hydrothece large, campanulate, with a plain circular margin, borne on ringed pedicels (about three rings), and somewhat spirally disposed. Gonothece unknown.
The calycles of this handsome species are distinguished from those of all the other members of the genus by their size and campanulate form. As I have already mentioned, they are about three times as large as those of L. dumosa, and are raised on a well-developed pedicel with three or four strongly marked annulations. Instead of being tubular, they are of a tall bell-shaped figure, expanding slightly towards the orifice. They occur in pairs, which spring alternately from different aspects of the stem, and assume therefore a somewhat spiral arrangement.
Though very abundant, LZ. grandis only occurs in fragments amongst the Icelandic dredgings ; but Sars’s figure* shows that it attains a luxuriant shrubby growth, rising to a height of about an inch and a half.

I have given my reasons elsewhere for identifying the L. fruticosa of Sars with Alder’s C.gracillima, notwithstanding the opposite decision of G. O. Sars}. In one of the plates which accompany this paper I have given figures, carefully drawn with the camera lucida, of the Norwegian and the British forms for comparison. Both the variety with a twisted pedicle, described by Alder as CO. gracillima, and the normal L. fruticosa occur amongst the Icelandic dredgings.
Calycella syringa, Linn.

The calycles about double the size they attain in British examples. The gonothece are borne plentifully on the Ice- landic specimens, and on others which I have received from Labrador. ‘They are comparatively rare on our coasts.

(G. O. Sars).
Calycella pygmea, Alder. Pl. VII. fig. 15. On other Hydroids.
Calycella obliqua,n.sp. Pl. VI. figs. 4, 5.
Stem erect, simple, rooted by a filiform stolon. Hydrothece alternate, elongate, tubular (height more than four times as great as the breadth), gracefully curved, the convex side upper- most, obliquely truncate above, furnished with an internal membranous operculum, and borne on short ringed pedicels. Gonothece unknown.
This very distinct and elegant form is at once distinguish- able from all its kindred by its obliquely truncate hydrothece. The wall of the calycle on one side for a short distance below the margin seems to be simply membranous, and to fold inwards slantwise across the tube, so as to form a kind of internal operculum.
Several specimens have occurred growing on other zoo- phytes.
Calycella quadridentata, n.sp. Pl. VIII. figs. 17-20.
Hydrothece cylindrical, usually slightly incurved on one side, the height about three times as great as the breadth, with a quadridentate margin and an operculum composed of four pieces, borne on ringed pedicels of variable length (3-7 rings), which rise at intervals from a creeping stem. Gonothece un- known.
This species, which bears a general resemblance to C. sy- ringa, is at once known by the quadridentate rim of the calycles and the quadripartite operculum. The denticles on the margin are well marked; and the operculum is composed of four broad and short segments, corresponding with the spaces between them; whereas in C. syringa it is made up of as many as eight or nine rather narrow and elongate pieces, forming a somewhat elevated cone (PI. VIII. fig. 24). The calycles are of the same general shape in the two species ; but the outline is stiffer and less wavy in C. syringa than in the present form. The pedicel of C. guadridentata 1s rather thicker than that of its ally, and is usually, as far as I have observed, short (3 or 4 rings), though sometimes the number rises as high as seven.

This elegant form is not uncommon amongst the Icelandic dredgings, creeping over other Hydroids.
Cuspidella humilis, Hincks. Creeping over the stems of Halecium crenulatum.
Lafoéina tenuis, M. Sars.
This remarkable Hydroid, first described by the elder Sars, and figured by his son in his recent paper on Norwegian Hydroida, occurs amongst the Icelandic dredgings, creeping over other zoophytes. The species may readily be mistaken for the Cuspidella humilis (mihi), from which it is chiefly di- stinguished by the very remarkable sarcothecee with which it is furnished. In preserved specimens these may be easily over- looked.
Filellum serpens, Hassall.
Creeping over the stem of other zoophytes. It has a wide distribution on the Norwegian coasts, and occurs at great depths as well as in shallower water.

Family Haleciide. Halecium muricatum, Ellis and Solander.
A few fragments with reproductive capsules. This species has been found off the coast of Labrador.
Halecium crenulatum, n.sp. Pl. VIII. figs. 21-23.
Stem compound, branched; branches straight, regularly crenulated above each joint. Hydrothece supported on very short lateral processes, single or in pairs, alternate, elongate, expanding gradually towards the margin, which is slightly everted, twisted at the base, bearmg a strongly annulated branchlet given off from the side. Gonothece ovate, shortly stalked, springing singly or in pairs from the lateral process beneath the calycle.
» The above diagnosis is of necessity defective; for though many fragments of the species occur amongst the Icelandic dredgings, I have not met with a specimen in a perfect con- dition, nor even with a piece of any considerable size. From an examination of the fragments, | am able to say that in its mature state it possesses a compound stem; but of the habit I can give no account; the portions from which my description is ee are either detached branches or impertectly
developec ots. The minute characters, however, are suffi-

ciently marked, and I have no doubt that the species is distinct from any hitherto described. It makes the nearest approach to H. labrosum, Alder; but its calycles are very different from those of the latter species. They are not annulated towards the base, nor have they the much everted rim so characteristic of H. labrosum. The lower portion, supporting the cup in which the base of the polypite is lodged*, is perfectly plain, or exhibits only a slight twist near the point of origin. The whole hydrotheca is trumpet-shaped, expanding gradually upwards towards the margin, which is but slightly everted. From the lower part, a little beneath the cup, a short, strongly annulated branchlet is given off. Frequently the primary ealycle supports a second, as is commonly the case in this genus, which rises from within it.
The stem is very regularly and distinctly crenulated above each joint; and thisgs a marked character, giving a very ele- gant appearance to the species. On the portions which I have had the opportunity of examining there were sometimes short branchlets alternating with the calycles, and exhibiting the same structure as the larger stems. The lateral processes supporting the calycles are very short. The gonothece are ovate, membranous, borne on a short stalk which is not ringed, and are developed on the lateral process. The stems are of a dark horn-colour.
Family Sertulariide. Sertularia tenera, G. O. Sars.
One or two specimens occur of this interesting form, which has recently been obtained at great depths (150 fathoms) off the coast of Norway by G. O. Sars.
Sertularella tricuspidata, Alder. Very abundant and fine.
Sertularella polyzonias, Linn. PI. VII. figs. 11, 12.
Abundant.
The robust habit and gigantic calycles give a very marked character to the northern variety of this common species. So distinctive is its appearance that, while there are no differences entitling it to specific rank, it is worthy of being recorded as S. polyzonias, var. gigantea, Sars mentions a robust variety
* The polypites of Halecium are only partially retractile; and little more than the base of the body is contained in the cup-like chamber which forms the upper portion of the hydrotheca. The lower sa is tubular, and in the present case almost eae throughout, whereas in H. labrosum it is strongly annulated near the base.

of this species which he had obtained from Greenland and Massachusetts; it may very probably be identical with the Icelandic form. Packard also tells us that in the Straits of Belle Isle (Labrador), S. polyzonias is found “ very stout and large ” in the deeper water.
Sertularella geniculata, n. sp. Pl. VII. figs. 13, 14.
Stems slender, decidedly geniculate, simple or slightly branched, jointed and twisted above each calycle; the internodes long, attenuated below, and bent in opposite direc- tions. Hydrothece very distant, ribbed transversely, chiefly on the upper half, rather broad below, and narrowing gradually towards the aperture, which bears four very prominent teeth, is sinuated deeply between them, and is surmounted by a conical quadripartite operculum. Gronothecee unknown.
Height (of the largest specimen met with) about 3 inch.
This is a critical species. In general character it closely resembles S. tenella, Alder; but, after careful examination, I feel little doubt that it is a distinct form. The stem is zig- zagged ; the internodes, which bend in opposite directions, are so much attenuated below as to have the appearance of distinct pieces jointed together rather than of the segments of a continuous stem. They are longer than those of S. tenella, and rather less decidedly twisted or annulated at the base. The calycles are about half as large again as those of the allied species ; they want the regular barrel-shape of the latter, are not rounded off below, but broad and squarish, and do not taper off so decidedly towards the upper extremity. They want altogether the constriction immediately below the aperture, which, to a greater or less extent, is found in 8S, tenella. The teeth are very large, prominent, and acuminate, and the margin is deeply sinuated between them; while in the last-named species they are comparatively incon- spicuous, and the rim is very slightly depressed between them. The aperture is ‘ conspicuously squared’ in S, tenella, and the operculum rises but little above it; in S. geniculata the operculum is prominently conical. The transverse ribs are much less pronounced, not giving the sharply crenulated appearance to the sides which they do in S. tenella; and they extend generally over a smaller proportion of the calycle. The contour and ‘ set”’ of the hydrothece are very different in the two forms, though it is very difficult to give an exact idea of the difference in a description. ‘The sides are rounded or curved outwards in S. tenella, almost straight in S. geniculata.
To sum up, the former species has neat, rounded, barrel-
Hydroida from Iceland. 153
shaped, strongly ribbed calycles, narrowed very decidedly towards the somewhat overhanging rim, which bears four short teeth, and is very little depressed between them ; the latter has large,straight-walled,somewhat broad-based calycles, not sharply carinated transversely, narrowing very gradually towards the margin, which bears four very prominent and pointed teeth, and is deeply sinuated between them.
The ramification of G. geniculata is peculiar. Branches are given off rarely at right angles to the stem, springing from the base of a calycle; sometimes two branches are developed at opposite points on the same internode. Not un- frequently the internodes comprising a shoot do not all le in the same plane; on the lower portion the calycles face one way and a different way above.
Notwithstanding the similarity in some points to S. tenella, I believe the present to be a well-established form, which.may properly be ranked as a species.
Amongst the Icelandic dredgings S. geniculata is not un- common.

I have also met with a characteristic specimen of this species. EXPLANATION OF THE PLATES. PuaTteE VI. Fig. 1. Lafoéa grandis, Hincks, magnified. Fig. 2. The same, more highly magnified. Fig. 3.

XXII.— Third Notice of a Collection of Fishes made by Mr. Swinhoe in China. By Dr. ALBert GUNTHER, F.R.S.
In the two previous communications on Mr. Swinhoe’s collec- tions of Chinese fishes published in this Journal for 1873 (Sept. pp- 239 -250, and Nov. pp. 877-380) the majority of species enumerated were from Shanghai, and only eleven from the more northern Chefoo. A case just received from this inde- fatigable zoologist contained collections made exclusively in the latter locality, adding much to our knowledge of its fauna. The species of tishes collected by Mr. Swinhoe at Chefoo amount now to forty-seven.
12. Mustelus manazo, Schleg.
13. Triacis semtfasciata, Girard. c 14. Raja porosa, sp. n.
Allied to Raja marginata. The anterior part of the snout is abruptly contracted into a narrow thin appendage ; the width of the interorbital space is more than one third of the distance of the eye from the end of the snout. Anterior profile un- dulated. Teeth in fifty-four or fifty-six series in the upper jaw, pointed in the male, flat in the female (as in the majority of the species of Raja). Superciliary margin with a series of spines; rostral process with small stellate asperities; a series of three or four spines in the median line of the back behind the head; tail with three series of spines in the male and with five in the female. The width of the disk is much more than the distance from the end of the snout to the hind margin of the ventral fin. Upper parts brown, with the snout white ; lower parts whitish, tmged with brown. The skin of the lower part of the snout and of the throat is perforated with numerous large pores, white in the centre and surrounded by a black ring.
The male is provided with a band of hooks near the angle of the pectoral fin and again on each side of the head, and the anterior margin of the disk is covered with asperities on its upperside in its whole length. The female is smooth on the parts just mentioned, but provided with a broad band of small hooks along the upperside of the posterior margin.

Molar teeth in four series above, and in three below. Dorsal spines very strong; the fourth, fifth, sixth, and seventh of nearly equal length, and half as long as the head. The second anal spine very strong, stronger, but not longer, than the dorsal spines. Caudal fin but slightly emarginate. Pectoral fin extending to the anal. Silvery ; a spot at the commencement of the lateral line, the operculum, a broad margin of the vertical fins, and the mem- brane of the ventral fins black.

One specimen, 15 inches long. A second, smaller specimen was obtained at Shanghai.
This species is closely allied to P. instdiator, from which it will be readily distinguished by its much smaller scales. The figure on which Richardson founded this species is very rudely executed, and the ridges are represented in the form of thorns ; however, the coloration shows that the artist has had before him the same species from which my notes are taken.

XXIV.—On the Dwarf Buffalo of Pennant. By Sir Victor Brooks, Bart., F.Z.S.
To the Editors of the Annals and Magazine of Natural History.
GENTLEMEN,
With reference to Dr. Gray’s remarks upon my paper on *‘ African Buffaloes” in the December number of your Journal (p. 499), I would merely ask any person interested in the matter to turn to Pennant’s ‘Synopsis of Quadrupeds ’ and to judge for himself as to the correctness of Dr. Gray’s state- ments. Pennant, in his description of the “ Dwarf” (p. 9), thus writes, ‘The horns of this animal are in the Museum of the Loyal Society, described by Grew, page 26,” and upon plate 8. figure 3 he figures these horns.
Turton, having founded the name Bos pumilus upon Pen- nant’s “ Dwarf,” it follows that the horns spoken of and figured by Pennant are typical specimens of “Bos pumilus.”
In the British Museum are a pair of horns, entered in the ‘ Hand-list of Edentate, Thick-skinned, and Ruminant Mam- mals’ (1873, p. 82) as received from the Museum of the Royal Society, which exactly agree with Pennant’s description and figure. There can theretore, I think, be no reasonable doubt that they are the identical specimens figured and described by Pennant.
These horns are likewise the type of Blyth’s Bubalus reclinis.

It is therefore clear that if I am right in considering Bu- balus reclinis to be the male of Bos brachyceros, both these names must give way to the older name of pumilus.
With regard to Dr. Gray’s general remarks on the character of my work and the accuracy of my synonyms, I do not care to reply to them, but leave future workers to judge between us.

On the Theory of the Process of Fermentation. 161
I shot two specimens of this very beautifully but subdued- coloured Sibia in April last, when making the ascent of the peak of Khtinho, Eastern Burrail range, Négd Hills, at about 8000 feet. The bird appeared pretty numerous, in companies of four to six or eight, haunting the tops of the rhododendron trees, then in full bloom, busily engaged searching for insects in the flowers, and their forehead, chin, and throat were covered thick with the pollen.
In the general distribution of the coloration and form it resembles S. gracilis, extremely common in the same locality, but seldom seen there above 6000 feet.
XXVI.—On the Theory of the Process of Fermentation. By Dr. H. KARsTen.
CAGNIARD DE LATOUR in 1836 recognized aleoholic fermen- tation as a physiological process dependent upon living crea- tures ; and I subsequently (in the ‘ Bot. Zeitung’ for 1848 and 1849) indicated the pathological nature of yeast, 7. e. that the yeast-cells were not true species of plants, as was supposed by Latour (and by Persoon, 1822), but pathological organizations. This view is now, after long discussion, making some way, in opposition to the opinion maintained by the majority of chemists (following Liebig) that fermentation is a purely che- mical process quite independent of any vital action. -
Although in 1870 Liebig admitted that alcoholic fermenta- tion is dependent on the presence of living yeast-cells, he en- deavoured, nevertheless, to preserve his previous opinion to a certain extent, by assuming that it was the fluid contents of the yeast-cells which effected the decomposition of the sugar, &c.
In accordance with the processes of decay in which the oxidation of the albuminous materials transfers itself to the neighbouring carbon compounds (a view, the incorrectness of which I demonstrated in ‘ Poggendorff’s Annalen,’ 1860), the process of fermentation is supposed to be dependent upon the decomposition of albuminous unorganized substances (outside the cell according to Liebig’s former opinion, but within it ac- cording to his present view), which then also seizes upon the surrounding molecules of complex carbon compounds.
But that even this last conception does not accord with the true nature of the process, and that the products of fermentation were generated by the vegetating membrane of the yeast-cell and not by its fluid contents, had already been demonstrated by me in my memoir on the Chemistry of the Vegetable Cell in 1869,
162 Dr. H. Karsten on the Theory
Probably Liebig would not have taken all these circuitous ways towards the natural explanation of the process of fermen- tation had he known that the yeast-cells, even though they do not increase (nay, perhaps may diminish) in weight, are yet constantly vitally active and engaged in continual new formation, and that during the growth of their membranes these finally become changed into vegetable acids, lactic acid, succinic acid*, and, if we may judge by the analogy of other processes, into glycerine, alcohol, carbonic acid, fat, &e.
Pasteur, who has so thoroughly studied the chemical pro- ducts of alcoholic fermentation, and so greatly increased our knowledge of them, and to whom we are indebted for finally setting free his confréres from the long persistent error that fermentation is a purely chemical act—even Pasteur, in his fresh attempt to establish a theory of the process of fermenta- tion (‘Comptes Rendus,’ 1872), struck upon the same rock, in thinking that the chemical processes of fermentation differ from a number of other phenomena, and especially from the actions of the other vital phenomena, by the circumstance that a much greater weight of the fermentescible substance is de- composed than the weight of the acting ferment amounts to. That this view is erroneous in every respect we see at once if we compare the quantity of nutriment of any animal with the weight of its body, and, on the other hand, consider the con- tinual regeneration of the yeast-cells, which was urged against Liebig in my ‘ Beitrag zur Geschichte der Botanik’ (1870).
Pasteur also believes that this fact of the inferiority of weight of the organized ferment is connected with its nourishment in the absence of free oxygen ; and he finds in this the distinguish- ing characteristic of fermentation as compared with other vital processes. ‘‘ Fermentation,” says Pasteur, “is a special case of a very general phenomenon; nay, we might say that all creatures, under certain conditions, are ferments. If we kill any creature, or organ in any creature, or a group of cells in this organ, by suffocation, by cutting through nerves, &c., the physical and chemical life in them will not immediately cease, it will continue ; and when this takes place under such condi- tions that free oxygen (interior or exterior) is wanting, then the organism, the organ, or the cells will necessarily derive the heat which they require for their processes of nourishment and growth from the substances surrounding them; they will consequently decompose these, and we shall see the peculiar character of fermentations appear, when the amount of heat developed represents the decomposition of a quantity of fer-

of the Process of Fermentation. 165
mentescible substances which is distinctly greater than the weight of the substance set in motion by the organism, the organ, or the cells.”
Pasteur, who seems here to agree with my opinion (first ex- pressed in the ‘ Botanische Zeitung’ for 1848) as to the vitality and faculty of increase of cells (¢. g. secretion-cells or embryonal tissue-cells) which have become diseased by abnormal condi- tions of nutrition, nevertheless, led astray by correctly ob- served but erroneously interpreted facts, mistakes the nature of a whole group of these pathologico-necrobiotic vital pro- cesses. The observation that beer-yeast growing upon the surface of a solution of sugar absorbs atmospheric oxygen, and converts it into carbonic acid without producing alcohol, whilst the same yeast when carried beneath the surface of the fluid by shaking produces alcohol as well as carbonic acid, has misled Pasteur to the assumption that oxygen regularly suppresses alcoholic fermentation.
Assuming that Pasteur’s statement is correct, and that yeast floating on the surface of a solution of sugar produces no alcohol, this does not prove that oxygen in such small quan- tities as the fluid dissolves prevents the formation of alcohol, and that the submerged yeast does not come into contact with oxygen. As fermentation is due to continuous regeneration and increase of the yeast-cells, and for the production of cells oxygen must necessarily lend its aid unless all our observa- tions are at fault, Pasteur’s proposition that oxygen uncondi- tionally prevents alcoholic fermentation must need modification as follows :—that the unobstructed action of the atmospheric oxygen upon yeast-cells prejudices their property of furnishing alcohol and carbonic acid as products of the assimilation of grape-sugar, inasmuch as it induces the cuticularization of the membrane of the yeast-cells (that is to say, its partial con- version into a resinous, fatty substance). It is well known that masses of yeast, after being dried in the air, furnish more alcohol on distillation than fresh undried yeast ; and all sorts of daily experiences with saccharine fruits and solutions seem to stand in opposition to Pasteur’s views.
Recently Pasteur has been confirmed in his opinion formed upon the observation of vegetating yeast by the analogous in- Te ebaein of a second fact, likewise correctly recognized.
ouverschel long ago (Poggend. Ann. xxii. 1831) ob- served that ripe saccharine fruits, when kept in carbonic acid, were apparently well preserved for a long time, but at last eae into alcoholic fermentation with indications of decay. asteur paler this experiment, and found that plums, grapes, melons, all acid fruits and many others, when kept in

carbonic acid for a time, passed into a state of alcoholic fer- mentation, whilst they still appeared externally to be perfectly sound and well-preserved. From twenty-four plums which had lain for a few days in carbonic acid, and had almost im- proved in apparent soundness and firmness of flesh, he obtained 6:5 grms. of absolute alcohol. In this case also Pasteur de- rives the alcoholic fermentation from the absence of oxygen.
I also obtained an alcoholic distillate from grapes and plums under similar circumstances, not only when they were pre- served in carbonic acid, but also in hydrogen or in an air-tight. vessel in atmospheric air (in the latter case the oxygen was probably soon converted into carbonic acid by the ripe fruits). Although no trace of mould or other signs of the commence- ment ot decay could be recognized, 36 cub. centim. of distillate contained 2°8 vol. per cent. of alcohol.
Moreover plums which had been kept for an equal time in pure oxygen (prepared ky the ignition of chlorate of potash) with hydrate of potash also furnished an alcoholic distillate ; nay, ripe figs which had lain in ozonized air showed signs of alcoholic fermentation by their odour and the commencement of yeast-formation in their cells. Under these circumstances also, just as when they had lain in carbonic acid and in hydro- gen gas, the fruits retained their normal sound appearance for weeks, and were not attacked by mould, whilst other similar fruits lying in the air had long been decayed and mouldy. On those plums which, as described, had been preserved under pure oxygen gas, a partial production of mould had certainly commenced; but for the purpose of distillation twenty-four well-preserved fruits, of perfectly sound appearance, with no signs of mould, were selected. Some similar fruits were ex- amined microscopically, and proved to be free from Fungi in the interior also.
Even in those experiments which furnished a distillate with a neutral reaction, alcohol was obtained, but 1 per cent. less than in those in which carbonic acid was employed. Other grapes and plums which were exposed to the atmosphere showed no trace of aleohol even when distilled over platinum- black.
Consequently the fruits which in other respects appeared sound, were affected and passed into alcoholic fermentation by excessive action of oxygen just as by other gases injurious to the normal assimilative activity, although (to judge from the results of distillation) this occurs rather later in oxygen gas than in the gases employed in the other experiments.
The exclusion of oxygen, therefore, is not the immediate cause of alcoholic fermentation and allied phenomena in the
of the Process of Fermentation. 165
organs and tissues fitted for them, but the abnormal processes of development of the embryonal cells contained in the tissue- cells, called forth by physico-chemical agencies, in the presence of sufficient quantities of grape-sugar or other bodies, cor- responding with other processes of fermentation and decom- position. Alcoholic fermentation, therefore, like the other processes of fermentation and decomposition, has its foundation in the necrobiosis of the organs and tissues in question.
The fruits are suffocated in the oxygen gas, and in the other gases employed, just as they are killed in every pure gas, in water free trom air, by mechanical injuries, &c.; the normal process of maturation is interrupted, in consequence of which, and the presence of sugar in their cell-fluid, the cellules con- tained in the latter or their endogenous new formations acquire the nature of yeast-cells. In figs and grapes this may be recognized* very easily even from the form of the yeast- cells thus produced; whilst in plums, as in the gooseberries which I employed formerly (see ‘ Botanische Zeitung,’ 1848) in experiments on fermentation in hydrogen gas, the newly formed cells acquire a globular form.
Even here it is proved that the kind of biological process of the cell-generations which develop themselves within dying tissue-cells is dependent upon the chemical nature of the cell- fluid and the matter and forces acting from without. The Vibrios and Bacteria do not originate putrefaction, nor does yeast originate fermentation, but rather the forms which the cells acquire are determined by the nature of the nutritive material. If the fluids are predominantly albuminous, putre- faction ensues with Bacteria and Vibrios; if they are saccha- rine, fermentation takes place with yeast, as I have demon- strated inmy ‘ Fiaulniss und Ansteckung’ (1872, p.2). Nay, according to the different chemical nature of the fluids, varia- tions of these processes will occur, presenting in their course the greatest similarity to the biological processes of normally assimilating secretion-cells, But in reality these morbidly developed cell-generations are completely different in their nature from the latter.
* In figs we may most easily convince ourselves of the production of east-cells within the tissue-cells during the sojourn of the fruit in car- basic acid, if we add to the microscopic section of such a fruit a portion of a solution of cane-sugar or sugar of milk, and then observe it for some - time. This object may be cemented down like a ee prepara- tion ; and it then slowly but surely shows the growth of the yeast-cells. Figs which had lain for eight weeks in carbonic acid without showing any signs of mould or changing much in form and colour, but which had a vinous-acid odour, were especially fitted to exhibit this development of the grape-sugar yeast.

The secretion-cells are subjected to the creative activity of a composite organism, the preservation and regeneration of which they subserve; their task is synthesis. On the con- trary it is the office of these ferments to decompose dead and dying organic substances into their simpler compounds, and to prepare them for decay ; their task is analysis. ‘To regard these ferment-cells (Hysterophymata) as equivalent to perfect organisms shows a complete misconception of their true nature.

“Contributions to the Study of the Errant Annelides of the Older Paleozoic Rocks.” By H. AtteyneE Nicnoxson, M.D., D.Se., M.A., Ph.D., F.R.S.E., Professor of Natural History in University College, Toronto.
In this communication the author endeavours to elucidate the abundant and obscure organic remains which are found so com- monly in the Paleozoic rocks, and especially in the Silurian strata of Britain, and which are generally known by the vague and con- venient names of “ Fucoids,” ‘‘ Annelide-burrows,” and “ tracks.” After expressing his opinion that the first step towards the study of these obscure fossils lies in the provisional grouping and naming of the more marked forms which are already known to exist, the author proceeds to divide the remains under consideration into two great groups. In the first of these groups are those fossils which are truly the burrows of marine worms, as distinguished from mere trails and surface-tracks. Some of these burrows (Scolithus) are more or less nearly vertical in direction as regards the strata in which they are found; and they are to be looked upon as beng true burrows of habitation. In this section are placed the genera Scolithus, Arenicolites, and Histioderma. Other burrows are of a totally different nature from the preceding, and may reasonably be compared to the burrows of the recent lobworms. These burrows run more or less horizontally as compared with the laminz of depo- sition, or they penetrate the strata obliquely. They are not bur- rows of habitation, but are wandering tunnels excavated by the worm in its search after food. The fossils of this group, there- fore, as preserved to us, are not the actual burrows themselves, but the burrows filled up with the sand or mud which the worm has passed through its alimentary canal. The burrows of this kind (including many forms previously described under the names
On the Errant Annelides of the Older Palwozoie Rocks. 167
of Chondrites, Paleophycus, &c.), the author groups together under the name of Planolites.
The second great group of Annelide-remains comprises genuine surface-trails or ‘“ tracks,” which of necessity never pass below the surface of the bed on which they occur. Some of these remains, such as Crossopodia, are, beyond doubt, due to the operation of marine Annelides ; but it may be a matter of question whether we have in these cases the actually petrified body of the worm, or merely the track produced by the passage of the animal over the surface of the mud or sand. The author, however, gives reasons for believing that the latter explanation is truly the correct one. Other fossils belonging to this group (such as Myrianites) are equally, beyond doubt, produced by the operations of marine animals ; but it remains quite uncertain whether they haye been formed by Annelides, Crustaceans, or Mollusks. Lastly, there are remains which appear to be really casts of the surface-trails of Annelides or other marine creatures, and which, therefore, are elevated above the surface of the bed on which they occur. Such remains may readily be confounded with those belonging to the genus Planolites, from which they are only distinguishable by the fact that they are strictly confined to a single surface of deposi- tion. To fossils of this nature the author proposes to restrict the generic title of Nemertites. .
Finally, the author describes some singular tracks apparently produced by Crustaceans belonging to the genus Ceratiocaris, and for which he proposes the generic name of Caridolites.

“‘ Experiments on the Development of Bacteria in Organic Infu- sion.” By C. C. Pope, M.B., Demonstrator to the Regius Professor of Medicine, and E. Ray LanxestEer, M.A., Fellow and Lecturer ~ of Exeter College.
The following passage from Dr. Charlton Bastian’s ‘ Beginnings of Life’ (vol. i. p. 429% induced us to make experiments similar to those mentioned in it, with the view of testing the correctness of Dr. Bastian’s conclusion as to matter of fact :—
“On the other hand, the labours of very many experimenters have now placed it beyond all question of doubt or cavil that living Bacteria, Torule, and other low forms of life will make their appear- ance and multiply within hermetically-sealed flasks (contaiming or- ganic infusions) which had been previously heated to 212° F., even for one or two hours. ‘This result is now so easily and surely obtainable, as to make it come within the domain of natural law.” And in a note is added, “In a very large number of trials I have never had a single failure when an infusion of turnip has been employed; and from what I have more recently seen of the effects produced by the addition of a very minute fragment of cheese to such an infusion (see Appendix C, pp- xxxiv—xxxvii), I fully believe that in 999 cases out of 1000, if not in every case, a positive result could be obtained.” Though this is one out of a great number of statements made by Dr. Bastian upon which he bases speculations as to the prevalence of spontaneous generation or archebiosis, we think it necessary to state that we have not considered that (which is a question of interpretation) as the point at issue, but merely the question of fact as to the appearance of Bacteria in what may be considered, accord- ing to our present lights, infusions duly guarded from inoculation. The point under discussion is one as to a fact in the natural history of Bacteria, in a further study of which we are occupied at the instance of the Radcliffe Trustees; and we believe that a more precise knowledge of the life-history, hfe-conditions, and

various forms of these organisms is necessary before the hypothesis of their spontaneous generation can serve as a safe guide in scientific investigation.
The experiments recorded below were made with infusion of hay and with infusion of turnip, sometimes with the addition of a few fragments of pounded cheese. It is necessary at once to call attention to three precautions which we have taken, and which we think are indispensable:—1. Recognizing the fact that the presence of lumps is a possible source of error, we excluded these from our infusion, either by filtration or by decantation. 2. To ensure the satisfactory exposure of the whole contents of the tube to the boiling temperature, we, as a rule, completely submerged our experimental tubes in boiling water for a period varying from five minutes to half an hour. 3.*The substances used in pre- paring the infusions being necessarily of a very heterogeneous nature, we always examined samples of the infusions before and after boiling, at the time of closing the tubes, and were thus able .to determine whether any change had taken place in the visible particles contained in the fluid after a lapse of time.
The microscopes used by us throughout, working side by side with samples from the same infusion, were a Hartnack’s Stative VIL. objective No. 10 4 immersion, ocular 4, belonging to the anatomical department of the University Museum, and a large Powell and Lealand belonging to the Radcliffe Trustees, which is provided with a ;, and a =, objective. The former of the two English glasses was more usually employed than the latter, on account of its greater convenience in manipulation.
Appearances in freshly prepared infusions.—Since the objects seen in such infusions are remarkable, and have doubtless some- times led to error in subsequent examination of infusions, we may draw attention to them now. In such freshly prepared infusions we have not unfrequently seen appearances agreeing very closely with some of those figured by Dr. Bastian in his book as coming into existence after boiling, sealing, and preservation in a warm chamber. A freshly prepared and boiled strong infusion of hay may present shreds of vegetable fibre, a considerable number of dead Bacteriwm termo (some two or three to the field), minute, highly refringent spherules, varying from the size of a blood- corpuscle to the smallest size visible; and such spherules are often present in pairs, forming figure-of-8-shaped bodies, both smaller and larger than Bacterium and of different optical character. Further, dumb-bell-shaped bodies are not unfrequently to be ob- served of similar form and size to Bacteria, but coarser in outline ; they dissolve on addition of HCl, which Bacteria do not*. All these bodies exhibit constant oscillatory (Brownian) movements. The addition of new cheese to such an infusion (as shown by

number of bodies similar to these were obtained ; and we suggest that they were of the same nature,

examination of a simple infusion of new cheese taken by itself) adds a considerable number of highly refringent spherules of various sizes (oil-globules) and finely granular flakes, also a few Bacteria and (if the cheese be not quite new, almost certainly) fungus-myce- lium and conidia in quantity.
Fresh-boiled turnip-infusion alone may contain so very few dead Bacteria that none are detected with the microscope, or only one in a drop. It presents a great number of minute, highly re- fringent spherules, varying in size from =),, inch downwards, all in most active oscillatory movement. Shreds and filaments of various sizes and character also are found, and a few finely granular flakes about j,4;5 inch in diameter. The addition of
T000 : cheese brings in, of course, the objects enumerated above as
belonging to it. ‘
Visibility of Bacteria—It is perhaps necessary to say, before proceeding further, that we have satisfied ourselves that, in infu- sions of the optical character of those used, the multiplication of Bacteria makes itself obvious by a cloudiness. Hence, though we have not remained content with that evidence, the retention by” such a limpid infusion of its limpidity is.a proof of the absence of Bacteria. We also should mention, what is well known already, that in a closed tube or bottle, after such a cloud (of Bacteria) has developed, the Bacteria at a certain period cease to multiply and settle down as a fine powder, leaving the fluid again clear. Such precipitated Bacteria remain unchanged in the fluid for a long period (weeks certainly, perhaps years), and can be readily shaken up and at once recognized by microscopic examination ; they are, moreoyer, not destroyed by boiling: hence it is not possible to miss the detection of a development of Bacteria in a limpid turnip- infusion, examined daily for three weeks or more by the naked eye, and finally, after agitation, by means of the microscope.
Series A. Noy. 23rd. Experiments with hay-infusion.—An in- fusion was prepared by pouring water of about 90° C. on to chopped hay. The infusion was of # dark sherry-colour ; reaction slightly acid. The glass tubes used in this and subsequent experi- ments were about five inches in length, of half inch bore, rounded at one end and drawn out to a capillary orifice at the other. The infusion in these and subsequent experiments was introduced by heating the tube and plunging its capillary beak beneath the surface of the experimental liquid during the cooling of the expanded air, until the tube was about one third or half filled. Tubes 1, 2, 3 were half filled with the hay-imfusion previously filtered, the liquid was boiled in the tube, and the capillary beak fused, as nearly as possible, during ebullition *.
* The tubes were sealed at the moment of removal from the flame over which they had been boiling. In every case a subsequent recurrence of ebullition was observed during the cooling of the upper part of the tube. Dr. Roberts, of Manchester, has suggested that the occurrence of Bacteria in tubes thus sealed may be explained by their in-draught, together with a certain amount of air, at the moment of closure; but the experiments of Sanderson, recently confirmed by Cohn, have shown that contamination of fluids by Bac/eria only takes place through the medium of impure surfaces or liquids.
On the Development of Bacteria in Organic Infusions. 171
Tubes 4, 5 were similarly treated, with the difference that a smal] quantity of cheese, in a very fine state of division, had been added to this portion of the hay-infusion before its introduction into the tubes.
Tubes 6, 7. Quantity and character of the infusion as in 1, 2, 3, but the tubes sealed without previous ebullition.
Tube 8. Quantity and character of the infusion as in 4 and 5, but the tube sealed without previous ebullition.
Tubes 9, 10, 11. Quantity and character of the infusion as in 1, 2, 3, but rendered slightly alkaline with KHO. Sealed approxi- mately during ebullition.
All these tubes (1 to 11) were after closure completely sub- merged in boiling water for fifteen minutes, and were then pre- served in a hot-air bath, varying in temperature from 30° C. to 35° C.
Microscopic and naked-eye appearances of the hay-infusion at the time of sealing the tubes.—The infusion in tubes 1, 2, 3, 6, 7 was clear and pellucid, that in tubes 4, 5, 8, 9, 10, 11 was hazy.
Microscopic examination gave the result indicated above, as to the appearances of freshly prepared hay and hay-and-cheese in- fusion.
Subsequent appearances of the infusion in Tubes 1-11.—The tubes with infusion which was pellucid at the first were found to retain this character for several weeks, being preserved in the air-bath and examined from day to day. The hazy infusions were opened after four days, and their contents found to be unchanged.
A portion of the same hay-and-cheese infusion, boiled aud pur- posely contaminated by preservation in an uncleaned beaker, was found after four days to be teeming with Bacterium termo exhibiting vital movements. The pellucid infusions were subsequently ex- amined with the microscope at different times and found to be unchanged.
Sertes B. Noy. 25th. Evperiments with turnip-and-cheese in- fusion.—An infusion was made with 700 grms. sliced white turnip and 1000 grms. water, to which about 1 grm. finely minced new cheese was added, the jug containing the mixture being maintained for four hours on a sand-bath at a temperature of 45°-55° C.
The infusion was now filtered; sp. gr. of the infusion 1011-1. Reaction slightly acid.
Tubes 12, 13, 14. Sealed cold. Submerged in boiling water for thirty minutes.
Tubes 15, 16, 17, 18, 19. Sealed approximately during ebulli- tion. Submerged in boiling water for thirty minutes.
The tubes were preserved in the air-bath as in Series A.
Microscopic and naked-cye appearances of the infusion at the time of sealing the tubes.—The liquid in all the tubes was perfectly clear and limpid. A few shreds and flakes were obvious, which appeared to be derived from the filter-paper and from the slight precipita- tion of albuminous matter. The microscopic appearances were those above described as characterizing such infusions.
172 Royal Society :-—
Subsequent appearances of the infusion.—The infusion in all the
tubes was found on examination from day to day to retain its lim- pidity. Subsequent microscopic examination of all the tubes at various periods subsequent to the closure of the tubes (from four days to three weeks) yielded no indication whatever of a deve- lopment of Bacteria or other organisms, nor of any change. A portion of the same infusion placed in an uncleansed beaker for comparison was milky and swarming with Bacteria after three days. Serres C. Nov. 28th. Experiments with turnip-and-cheese infu- sion.—The infusion similar in all respects to that in series B, but prepared with a somewhat larger proportion of turnips; there- fore of higher specific gravity, which was not numerically deter- mined.
Tubes 20, 21, 22, 23. Boiled and sealed approximately during ebullition. Not subsequently submerged.
Tubes 24, 25. Boiled and sealed approximately during ebullition. Subsequently submerged in boiling water during thirty minutes.
The tubes were preserved in the air-bath as in Series A and B.
Serres D. Noy. 30th.—An infusion prepared as in Series B and C, but brought to a sp. gr. 1031 by evaporation after filtration.
Tubes 26, 27, 28, 29. Sealed cold. Subsequently submerged in boiling water for thirty minutes.
Tubes 30,31. Boiled and sealed approximately during ebullition. Not subsequently immersed.
Tubes 32, 33. Boiled and sealed approximately during ebullition. Subsequently submerged in boiling water for thirty minutes.
Appearances in the infusions, Series C and D, at the time of sealing and submerging.—The appearances in the freshly prepared infusion were similar to those described above as characterizing such infu- sions.
Subsequent naked-eye examination of the tubes did not reveal the slightest change ; they remained limpid. Specimens from each group were opened and examined with the microscope after four days, and the microscopic characters found to be unchanged: the liquid was perfectly sweet. The remaining tubes were examined at intervals before the end of December, being maintained during the whole time at a temperature of 35° to 40°C. in the air-bath ; they equally proved to have remained unchanged when opened and examined with the microscope, and were also free from unpleasant smell.
Sertes E. Noy. 28th.—Six porcelain capsules were heated to redness, and nearly filled with the turnip-infusion used in Series C. They were placed on the air-bath under a glass shade.
Capsules 1, 2. The infusion was unboiled.
Capsule 3. The infusion was boiled in the capsule.
Capsule 4. The infusion was introduced after it had been boiled for five minutes in a superheated test-tube.
Capsules 5 and 6. The infusion was that used in capsule 4, but a drop of distilled water was added to each of these two capsules.
On the Development of Bacteriain Organic Infusions. 173
After four days the infusion in capsules 1, 2, 5, and 6 was found to be teeming with Bacterium termo and Bacterian filaments.
Capsule 3 was found to be cracked, and hence was discarded (it swarmed with Bacteria).
Capsule 4 was perfectly free from organisms, and remained so during a fortnight, when a fungus-mycelium made its appearance on the surface.
Series F. Dec. 10th.—A strong infusion of turnip and cheese, prepared as in Series B (sp. gr. 1013), was boiled in an eight-ounce flask for five minutes. Three common test-tubes were superheated and placed in a beaker to support them.
No. 1. The infusion was poured in, and with it one drop of distilled water.
No. 2. The infusion was poured in and thus left.
No. 3. The infusion was poured in and again boiled for two minutes.
These and the flask containing the remaining infusion were left on a shelf for one day; on Dec. 11, there being no cloudiness in any of the four, they were placed on the top of the hot-air bath. On Dec. 13 No. 1 was found to be swarming with Leptothria-growths and free Bacteriwm termo.
No. 2 also was cloudy and swarmed with what Cohn calls the rosary-chains. No. 3 was absolutely free from all development of life, and was perfectly sweet and limpid ; so also was the fluid in the original flask, a large one capable of holding eight ounces. How is the development of Bacteria in No. 2 to be explained? The original fluid remains pure; the fluid in No. 3, which was reboiled, remains so too; the tube itself, No 2, had been heated red-hot and could not be a source of contamination. One’s attention was therefore directed to the conditions of the passage of the fluid from the flask into the tubes ; and here an explana- tion at once offered itself. The large flask had not been super- heated ; its lip was still dirty, laden with Bacteria ready to con- taminate fluids as they poured from it ; hence the contamination of the fluid in test-tube No. 2. The validity of this explanation can- not be disputed, because it is known that such glass surfaces, unless specially cleansed, invariably contaminate infusions exposed to them.
Serres G. Feb. 11th.—The publication of Dr. Burdon Sander- son’s letter, describing some experiments made by Dr. Bastian, induced us to make a further series of experiments with impor- tant modifications. We had expressly avoided the introduction of any thing like visible lumps of solid cheese or turnip into our infusions during their ebullition, believing that such lumps were a possible source of the exclusion of Bacteria or their germs from the killing influence of the boiling temperature. This precaution we had supposed (in the absence of any statement to the opposite effect) to have been taken by Dr. Bastian in the experiments adduced by him in the ‘ Beginnings of Life.’ The presence of such lumps was publicly suggested in discussion at the British-Asso-
Ann. & Mag. N. H. Ser. 4. Vol. xiii, 13

ciation Meeting at Liverpool as a source of fallacy, and has been demonstrated to be so by Dr. Ferdinand Cohn in experiments made with peas and infusion of peas (‘ Beitriige zur Biologie der Pflanzen,’ Breslau, 1872). Further, we had limited the bulk of our infusions and the size of our experimental tubes, in view of the obvious consideration that the larger the mass and area to be guarded against contamination the greater the chance of failure in that respect. Thirdly, it had not occurred to us to make use of vessels in these experiments of a form so inconvenient and diffi- cult to thoroughly guard against effects of “ spluttering,” and to thoroughly heat by boiling, as the retort. Nor could we guess, in the absence of any directions on that poimt from Dr. Bastian, that it was desirable to exclude the rind of the turnip from the preparation of the infusion. The correspondence in ‘ Nature,’ however, indicated that “ pounded ” cheese (necessarily in a condi- tion of solid lumps) was added (in some cases) to his experimental vessels after the turnip-infusion, and was present during ebullition. It also appeared that retorts capable of holding two ounces were the vessels used; whilst, on grounds not given, it was considered advantageous by Dr. Bastian to peel the turnips before slicing them.
The following experiments were accordingly made :—
An infusion of turnip (minus the rind) was prepared and filtered ; it had sp. gr. 1012-7. In the experiments Nos. 34 to 47 two-ounce retorts were used, and the bulb half filled with the experimental infusion.
No. 34. The infusion neutralized with KHO. About two grains of pounded cheese in pellets added to the retort.
Nos. 35, 36. Infusion not neutralized. About two grains of pounded cheese in pellets added to the retort.
Nos. 37, 38, 39. The simple infusion.
No. 40. The simple infusion, to which were added a few drops of an emulsion of cheese prepared with some of the turnip-infu- sion and new cheese, the emulsion having been filtered.
No. 41. The simple infusion.
Nos. 34 to 40 were boiled for five minutes; they were then pre- served in the air-bath at a temperature of 35° C., and sealed approxi- mately during ebullition. Four of them, including No. 36, were subjected to a further boiling of fifteen minutes in a water-bath after sealing.
No. 41 was boiled for five minutes and placed on a shelf with its mouth open.
Subsequent appearances in Retorts Nos. 34-41.
On Feb. 15th Nos. 34, 35, 37 were opened and found to be perfectly sweet and free from a development of Bacteria or other organisms.
No. 41 was observed to be perfectly limpid, and is so siill (March 17th).
On Feb. 27th Nos. 36, 38, 39, and 40 were opened. With the
On the Development of Bacteria tn Organic Infusions. 175
exception of No. 36, they were perfectly sweet and free from organisms.
No. 36 had a slightly foetid odour and swarmed with rather long Bacteria—that is, Bacizria longer than the common B. termo, which develops in infusions open to atmospheric air, but not quite of the form of the Bacillus subtilis of the butyrie fermentation, which is stated to appear in some infusions, ¢. g. milk, to which the access of atmospheric air has been entirely prevented. It is to be noticed that in this series the only retort in which Bacteria made their appearance was one of those in which small Jumps of cheese were present during the subjection of the flask to the process of ebullition and subsequent immersion in boiling water.
This result induced us to make a further series of differential experiments, bearing upon the influence of the state of aggre- gation of the cheese introduced into the turnip-infusion.
Serres H. March 8th.—A turnip-infusion was prepared as in Series B ; found after filtration to have sp. gr. 1115-5.
Tubes similar to those used in Series A—H, and half filled, were used.
Tubes 42, 43, 44. The simple infusion was poured into the tube, so as to half fill it; a lump of cheese the size of a pea was then added. Sealed cold.
Tubes 45, 46, 47. To the turnip-infusion, before introduction into the tubes, an emulsion of cheese prepared with turnip-infusion and strained through a piece of cambric was added. The tubes were then half filled with this mixture and sealed cold.
Tubes 48, 49,50. The same as 42, 43, 44, but sealed approxi- mately during ebullition.
Tubes 51, 52,53. The same as 45, 46, 47, but sealed approxi- mately during ebullition.
All the tubes, 42 to 53, were completely submerged during five minutes in boiling water, and subsequently preserved in the air- bath at 35° C. temperature.
On March 13th the contents of the twelve tubes were examined with the microscope. No. 45 had been broken in the boiling. The five remaining tubes which had been prepared with cheese in the finely divided condition were found to be entirely devoid of life, the infusion microscopically and otherwise unchanged. Of the six tubes prepared, each with a small lump of cheese, no organisms were detected in 42 and 44; but in 43 and 49 a few elongate Bacteria were observed (in the proportion of about two to the field of a Hartnack’s system 10). In 48 and 50 the fluid was swarming with elongate Bacteria and true Bacillus. The lumps of cheese in those tubes in which life appeared had softened and spread out to a certain extent on the side of the tube. The cheese-lumps in Nos. 42 and 44 retained their original form.

tian’s mode of treating turnip and cheese so as to obtain phenomena supposed to be in favour of the doctrine of Archebiosis, we consider that the importance of excluding visible lumps from the experi- mental infusions is clearly indicated, as also is the comparatively greater trustworthiness of the small tube as opposed to the larger retort for use as an experimental vessel. We moreover consider that we, in our earlier experiments (November and December), carefully following Dr. Bastian’s directions, as far as he had given any in the ‘ Beginnings of Life,’ but using at the same time proper care as to cleanliness and due boiling, obtained a series of results contradicting Dr. Bastian’s statements as to the spontaneous genera- tion of Bacteria in infusion of turnip to which a fragment of cheese had been added.
Further, certain of the experiments above recorded, and others made at the same times with open vessels and simple turnip-infu- sion, compel us to dissent emphatically from the conclusion of the following statement contained in a recent paper by Dr. Bastian (‘Nature,’ Feb. 6th, p. 275):—‘“ Taking such a fluid, therefore, in the form of a strong filtered infusion of turnip, we may place it after ebullition in a superheated flask, with the assurance that it contains no living organisms. Having ascertained also, by our previous experiments with the boiled saline fluids, that there is no danger of infection by Bacteria from the atmosphere, we may leave the rather narrow mouth of the flask open, as we did in these experiments. But when this is done, the previously clear turnip- infusion invariably becomes turbid in one or two days (the tem- perature being about 70° F.), owing to the presence of myriads of Bacteria.” The italics are our own.
We find not only that such an infusion remains free from Bacteria when thus treated (subject, of course, to certain failures in the precautions taken) for “ one or two days,” but if contamination by the admission of coarse atmospheric particles capable of carry- ing Bacteria be guarded against, it will remain so for weeks and probably for years. In consequence of this absence of develop- ment of Bacteria we have cultivated Torule in such a turnip- infusion, so as to obtain them entirely free from the former organisms*.
Tn conclusion, we would point out that failure in manipulation, contamination in unsuspected ways, such as that due to the pre- servative influence of lumps, and, again, the mistaking of particles in an infusion which have been there from the first for organisms originated de novo, do not exhaust the list of conceivable explana- tions of phenomena which have been attributed to spontaneous generation. When the knowledge of the natural history of Bacteria has advanced somewhat further, there will be a possibility of such explanations presenting themselves in ways at this moment un- suspected.
* At this moment, May 20th, the turnip-infusion in the open retort (No, 41) is free from all organisms, and is perfectly limpid and sweet.
On High-Power Definition. 177
Whilst awaiting Professor Huizinga’s fuller account of his experi- ments, we may point out that the hypothesis of an inhibitory influ- ence of increased density should be supported by experimental evidence, and that it cannot apply to tubes closed before boiling. The neck of the flask closed with asphalt may (so far as condi- tions are stated by him at present) harbour Bacteria, as in our Series F. But especially we would urge upon him and others that it is undesirable, as yet, to introduce into the discussion other organic mixtures. Turnips and cheese may be very bad material for experiment ; but it would be well, as far as possible, to settle the matter, or the way in which the matter is to be viewed with regard to them, before going off to other particular cases.
It would be a very excellent thing if all further reference to this subject could be postponed for a year or two—that is, until further study of Bacteria, such as that inaugurated by Sanderson and Cohn, has given us surer ground to tread upon.

Mr. Beau- mont’s surprise and admiration equalled that of Dr. Pigott. This circumstance will excite no surprise when it is stated that for four years the spherules of the Podura have been generally denied and warmly disputed. In ordimary cases a crushed scale shows nothing ; and as glasses are usually corrected to show the illusory spines or markings, these spherules are concealed.
The idea conveyed was, that two layers of spherules (first de- tected by Mr. Beaumont within the tubes), like two confined layers of small shot, had, by compression, been forced and largely spread out into broader layers. It was thought also that detached portions resembled Jong tubes or puckers filled with spherules exactly fitting them. ‘The spherules appeared perfectly spherical, but somewhat unequal in size.
In the general flattened and extended surface of the compressed and disintegrated scale the spherules appeared dark blue or red, according to the slight change in the focal plane, and in a still lower plane white.
In the adjoining uninjured scales long strings of beads were seen, like necklaces of coral, here and there sharply bordered with black lines, apparently denoting tubes of membrane or puckers enclosing them like a tube. Between these strings of spherules peeped forth others of a light orange-colour.
The slide was an old one and well known. ‘The mass of the crushed scale occupied a much broader space than any of the scales.

“‘ Note on the Electrical Phenomena which accompany irritation of the leaf of Dionwa muscipula.” By J. Burpon SaNnDERSON, M.D., F.R.S., Professor of Practical Physiology in University College.
1. When the opposite ends of a living leaf of Dionea are placed on non-polarizable electrodes in metallic connexion with each other, and a Thomson’s reflecting galvanometer of high re- sistance is introduced into the cireuit thus formed, a deflection is observed which indicates the existence of a current from the proximal to the distal end of the. leaf. This current I call the normal leaf-current. If, instead of the leaf, the leaf-stalk is placed on the electrodes (the leaf remaining united to it) in such a way that the extreme end of the stalk rests on one electrode and a part of the stalk at a certain distance from the leaf on the other, a current is indicated which is opposed to that in the leaf. This 1 call the stalk-current. To demonstrate these two currents, it 1s not necessary to expose any cut surface to the electrodes.
Electrical Phenomena in the leaf of Dioneea muscipula. 179
2. In a leaf with the petiole attached, the strength of the current is determined by the length of the petiole cut off with the leaf, in such a way that the shorter the petiole the greater is the deflection. Thus in a leaf with a petiole an inch long, I ob- served a deflection of 40. I then cut off half, then half the remainder, and so on. After these successive amputations, the deflections were respectively 50, 65, 90, 120. If in this experi- ment, instead of completely severing the leaf at each time, it is _ merely all but divided witha sharp knife, the cut surfaces remain- ing in accurate apposition, the result is exactly the same as if the severance were complete; no further effect is obtained on separating the parts.
3.. Effect of constant current directed through the petiole on the leaf-current.—If the leaf is placed on the galvanometer electrodes as before, and the petiole introduced into the circuit of a small Daniell, a commutator being interposed, it is found that on directing the battery-current down the petiole (i. e. from the leaf), the normal deflection is increased ; on directing the current towards the leaf, the deflection is diminished.
4. Negative variation.—a. If, the leaf being so placed on the electrodes that the normal leaf-current is indicated by a deflection lefiwards, a fly is allowed to creep into it, it is observed that the moment the fly reaches the interior (so as to touch the sensi- tive hairs on the upper surface of the lamina), the needle swings to the right, the leaf at the same time closing on the fly.
b. The fly having been caught does not remain quiet in the leaf ; each time it moves, the needle again swings to the right, always coming to rest in a position somewhat further to the left than before, and then slowly resuming its previous position.
c. The same series of phenomena present themselves if the sensitive hairs of a still expanded leaf are touched with a camel- hair pencil.
d. If the closed leaf is gently pinched with a pair of forceps with cork points, the effect is the same.
e. If the leaf-stalk is placed on the electrodes, as before, with the leaf attached to it, the deflection of the needle due to the stalk- current is increased whenever the leaf is irritated in any of the ways above described.
vé If half the lamina is cut off and the remainder placed on the electrodes, and that part of the concave surface at which the sen- sitive hairs are situated is touched with a camel-hair pencil, the needle swings to the right as before.
g. If, the open leaf having been placed on the galvanometer electrodes as in a, one of the concave surfaces is pierced with a pair of pointed platinum electrodes in connexion with the opposite ends of the secondary coil of a Du Bois-Reymond’s induction apparatus, it is observed that each time that the secondary cir-
cuit is closed the needle swings to the right, at once resuming its former position in the same manner as after mechanical irritation. No difference in the effect is observable when the
186 Miscellaneous.
direction of the induced currents is reversed. The observation may be repeated any number of times; but no effect is produced unless an interval of from ten to twenty seconds has elapsed since the preceding irritation.
h. If the part of the concave surface of the leaf which is nearest the petiole is excited, whether electrically er mechanically, the swing to the right (negative variation) is always preceded by a momentary jerk of the needle to the left, i.e. in the direction of the deflection due to the normal leaf-current; if any other. part of the concave surface is irritated, this does not take place.
1. Whether the leaf is excited mechanically or electrically, an interval of from a quarter to a third of a second intervenes between the act of irritation and the negative variation.

Observations on the Existence of certain Relations between the Mode of Coloration of Birds and their Geographical Distribution. By M. A. Mirne-Epwarps,
In carrying on my researehes on the geographical distribution of animals in southern regions, I have been struck with certain relations which seem to exist between the parts of the globe inhabited by birds and the mode of coloration of those animals; and wishing to know the degree of importance that ought to be ascribed to this observation, J have tried to examine more carefully than had previously been done what may be called the geographical distribution of colours in birds. In fact this investigation seemed to me capable of throwing some light on the influence which local biological conditions may exert upon the secondary zoological characters of species and races. To furnish significant results it ought to bear principally upon the natural groups which have a very wide geographical distribution ; and in order that it may have the necessary degree of precision, it ought ta be founded upon the chromatic analysis of the plumage and the comparison of its colours with well-defined normals. With- out the aid furnished by the chromatic circles, for which science and the arts are indebted to M. Chevreul, it would have been difticult for me to appreciate thoroughly the tones and shades which I had to take into account, and still more difficult to formulate clearly the results furnished by observation; but by means of these circles this labour has been remarkably facilitated.
_ Ina first series of investigations I attended specially to various degrees of melanism ; and in order to judge of the relative influence of black upon the plumage of birds inhabiting various geographical regions, I took into account not only the extent of the parts of the tegumentary system which are tinted in that manner, but also the degree in which the other colours may be dulled or modified in their tone by mixture with black in various proportions,
Miscellaneous. 181
Birds with black plumage are found in nearly all parts of the globe ; but in certain families, of which the geographical extension is very wide, the tendency to melanism is scarcely shown except in the southern hemisphere, and, more particularly in the oceanic region which includes New Zealand, Papuasia, Madagascar, and the inter- mediate countries. A remarkable example of this coincidence between the mode of coloration of birds and their distribution on the surface of the globe is furnished by the family of the swans. In the nor- thern hemisphere this family has numerous representatives whose plumage is entirely white ; in the southern hemisphere this is not the case, and a more or less considerable portion becomes intensely black. Thus the Australian swan is almost entirely black ; the cos- coroba, or Cygnus anatoides, which is confined to the Fuegian archi- pelago and neighbouring countries in South America, has some of the wing-feathers black, and if is by this character alone that it differs from the Chinese coscoroBa (C. Davidii); lastly, in the swan of Chili, the head and neck are jet-black, whilst the rest of the body is pure white. These are the only species of swans which live in the southern hemisphere.
These peculiarities would have but little interest if they were isolated: but this is not the case ; and the examination of the geo- graphical distribution of the colours of the parrots furnishes us with still more manifest proofs of the tendency to melanism in the vast oceanic region which includes New Zealand, Papuasia, and the in- termediate lands.
Black or nearly black parrots are not met with in America, Asia, or Africa (except on the borders of the Mozambique channel), but they are not uncommon in the southern region contained within the limits already mentioned ; and it is there especially that we find the species or local races in which the plumage only presents strongly toned-down tints. Thus, in New Zealand and the adjacent islands, these birds, instead of presenting bright colours, are more or less tinged with black. The Nestors, for example, Have dull brown plu- mage ; the larger feathers of the wings and tail, wherever they are exposed to the light, are almost uniformly of a brown tint, resem- bling that produced by a mixture of nine parts of black with one part of orange-red ; on the shoulders, the greater part of the back, the head, and the breast the feathers have a brown border of a still deeper tint ; and in the rest of their surface similar tints are miti- gated by white, so as to become more or less greyish ; and it is almost solely on the tail-coverts and the inner surface of the wings and on the corresponding portion of the flanks, which are not habitually exposed to the light, that an orange-red colour but slightly toned down shows itself here and there.
The Strigops or night-parrots of New Zealand also in great part owe their peculiar aspect to another kind of melanism, affecting a greenish ground, and mixed with parts modified by albinism. This yellowish green, which belongs to Nos. 3 and 4 of the chromatic circles, is far from being pure ; it is toned down by about ;4; or +4, of black, and is interrupted above by spots and irregular bands of
182 Miscellaneous.
nearly pure black and also by whitish streaks, whilst below and on the sides of the head the spots are due almost entirely to albinism. These mixtures, in which black plays a great part, produce a dull and speckled plumage which, up to a certain point, resembles that of our owls.
The tendency to melanism occurs also in the parroquets of New Zealand. These birds belong to the group of the Platycerci of which ornithologists have formed the genus Cyanorhamphus. Its plumage is of a dull green; a little pure red or yellow is still to be seen on the forehead or on some other very restricted parts; all the upper part of the body of the bird is of a yellowish-green colour much toned down with black, and below a similar but lighter tint spreads almost uniformly. In Cyanorhamphus alpinus the dominant colora- tion nearly corresponds to the yellowish green of the gamut No. 4, toned down by ;3; of black; in C. nove-zelandie, the yellowish green belongs to the gamut No. 2 and to that No. 3, but it is dulled by 35 of black; lastly,in C. auwriceps the general tint of the plumage agrees with the yellowish green No. 1, toned down by 5; of black over the whole upper surface of the body.
The islands of the great Indo-Pacific Ocean which are near Africa resemble New Zealand as regards the coloration of the plumage of their parrots. Thus in Madagascar, in the Mauritius to the east, and in the Seychelles and Comoro islands towards the north, and even on some parts of the neighbouring shore of Africa, we find several black species of parrots belonging to the genus Coracopsis.
In Australia the Calyptorhynchi abound ; and the whole of their plumage is of an intense black colour or softened with white. Many of the Australian parroquets have pure colours in the same degree as those of America; but in many of these birds the tendency to melanism makes its appearance in various parts of the body, some- times by the existence of a uniform tint very much toned down, and sometimes by the whole basal part of the feathers being invaded by black, which only bears near the margins a more or less narrow band of red, yellow, green, or blue.
In the memoir, of which I could only give a short abstract here, I review several other ornithological families which have furnished analogous facts and show the same tendencies—for example, the families of the Kingfishers, Rallide,and Ducks. But I have no space to speak of them here ; and the facts which I have indicated suffice to show that in the southern Indo-Pacific region the ornithological types which elsewhere are clothed with brilliant colours, generally have tints toned down with black or weakened by a tendency to albinism. —Comptes Rendus.

On the Genus Callignathus and on Kogia Floweri of Dr. Gill. By Dr. J. E. Gray, F.R.S. &e.

Miscellaneous. 183
Kogia Flower, from Mazatlan, Lower California—described from a specimen consisting of the front of a lower jaw, and from the figure and notice of the animal, measuring nine feet in length, recently for- warded to him by Colonel Grayson. It is very interesting as proving that this genus is found in the North Pacific. The account and figure of Dr. Gill are so very like that of Kogi«a MacLeayi that I should not be at all surprised if Kogia breviceps from the Cape of Good Hope, Kogia MacLeayui from Australia (which has been proved not to be distinct from the. skull of Physeter simus from the east coast of India), and Koga Flowert from Mazatlan are all the same species, naturally inhabiting, like the sperm-whale, the tropical regions and wandering to the north and south, as the same species has been found on both sides of the equator.
From the comparison of the photographs which Mr. Krefft sent me, with the skull from Madras (described by Professor Owen) in the British Museum, I could find no difference, as stated in the ‘Cata- logue of Seals and Whales in the British Museum,’ 1866, p. 392 ; and the comparison of the skulls since sent by Mr. Krefft has established the identity of the Australian specimens from the south and Indian from the north of the equator. Dr. Gill, having over- looked this observation (published in 1866), observes that a generic name will sooner or later be desired for Kogia stmus from Madras, and therefore proposes to call it Callignathus simus (p. 738)—and copies Owen’s figure of the young skull (p. 741, figs. 168-171), which is not to be confounded with the skeleton that Professor Owen copies from Krefft’s photograph of Zuphysetes Grayit, quite a distinct whale of the same group.
On'the Development of the Phragmostracum of the Cephalopoda, and on the Zoological Relations of the Ammonites to the Spirule. By M. Munter-Cuarmas.
I have the honour to submit to the Academy the results of the observations which I have made on the development of the phrag- mostracum of the Cephalopoda in the laboratory of paleontological research at the Sorbonne, under the guidance of M. Hébert.
This comparative embryogenic investigation proves very clearly that the Ammonites are not tetrabranchiate Cephalopoda allied to the Nautili, as is generally supposed, but dibranchiate decapod Cephalopoda, having the greatest affinity to the Spirule.
As early as 1867 M. J. Barrande had proved, in his great work on the Silurian system of Central Bohemia, the small resemblance that exists between the Goniatites and the Nautilide during the first period of their development. In fact, the initial chamber of the phragmostracum of the Cephalopoda of the Nautilide group, except as regards the external cicatrix, does not sensibly differ in its general organization from the other primary chambers which are developed a little later. In speaking of Cyrtoceras M. Barrande moreover expresses himself as follows.:—*: We shall also call attention to the
184 Miscellaneous.
fact that this form of the origin of the shell, which occurs also in Orthoceras, appears to be similar in all the types of Nautilide in which we have observed it hitherto. It contrasts, on the other hand, with the origin of the shell of the Goniatites, which appears in the form of an egg, isolated from the first air-chamber by a distinct con- striction.”
This initial chamber (ovisac) of the Goniatites, so different from those which immediately succeed it, is met with at the origin of the phragmostracum of all the dibranchiate Cephalopoda that I have been able to study.
The new and very interesting investigations carried on at Philadelphia by Mr. Hyatt, upon the embryogeny of the phragm- ostracum of Nautilus pompilius, Deroceras planicosta, and the Goniatites, come in support of these observations. It must be added, however, that Mr. Hyatt, preoccupied by his theoretical ideas upon the evolution of living creatures, in order to establish the filiation of the Ammonites and Nautzli, supposes that the latter lost their ovisac by truncation. ‘To support this supposition, he adduces the transverse external cicatrix which he observed on the initial chamber of Nautilus pompilius.
The numerous observations which I have since been able to make upon the termination of the siphon in Aturia zigzag, in the Jurassic, Cretaceous, and Tertiary Nautilz, and in the three existing species, the microscopic examination of a transverse section of the initial chamber of Nautilus pompilius and WN. umbilicatus, and a careful comparison of those Silurian Cephalopoda which lose the extremity of their phragmostracum by truncation have led me to a result completely opposed to the theoretical views put forward by Mr. Hyatt, but conformable in all points with the facts observed by M. Barrande.
The comparative examination which I have made of the ovisacs of Spirula Peronw and of Ammonites Parkinsoni, A. ooliticus, A. mamillaris, &c. has shown me the relations which exist between these two types during their embryonic evolution. In fact, in the Spirule and the Ammonites the siphon originates in the ovisac a little before the appearance of the first septum. It commences by a czcal inflation, which bears the prosiphon in its prolongation. The new organ to which I give the name of prosiphon must take the place of the siphon during the embryonic period. It originates in the ovisac, opposite the siphonal inflation, upon which it terminates, but without having any internal communication therewith. It is very variable in its general form, and may present a strongly marked example of dimorphism in the same species of Ammonite. It is formed by a membrane, which is sometimes simply spread out as in Spirula Peronii, or which may form a more or less circular tube. It also sometimes presents two, three, or four small subdivisions at its point of insertion upon the inner wall.
I have ascertained the presence of an ovisac in the genera Belemmites, Belemnitella, Beloptera, Belopterina, Spirulirostra, Am- momtes, and Ceratites. In Deroceras, Clymenia, and Goniatites its
Miscellaneous. 185
general form and its relations with the siphon are the same as in all the Ammonites. It is generally spheroidal when the turns of the spire are free, and ovoid when they are contiguous.
In the tetrabranchiate Cephalopoda which live in our present seas and in all those which swarmed by thousands in the ancient seas, the presence of an ovisac has never been detected. In Nautilus and Aturia the siphon originates upon the inner walls of the first chamber. It is completely closed at its posterior extremity by a part of the calcareous prolongation of the septum which assists in its formation. The external transverse cicatrix observed by Mr. Hyatt can never have been in communication with the siphon; its purpose is still completely unknown. It has been indicated by M. Barrande upon a great number of Silurian Tetrabranchiata.
Thus it results from these observations that at the Silurian epoch the tetrabranchiate Cephalopoda were as clearly separated from the dibranchiate as at the present day. The only modifications that we can recognize are of generic rank; in fact the Ammonites which, when young, have septa like those of Deroceras and Goniatites, appear to be derived from one of those types.—Comptes Rendus, December 29, 1873, pp. 1557-1559.
On the Endomycict. By the Rev. H. S. Gorman. To the Editors of the Annals and Magazine of Natural History.
GenTLEMEN,—My attention has been called to a brief notice you have given of my descriptive catalogue of the Endomycici. The question of classification, I venture to submit, is rather an experi- mental than a logical one, and must be influenced by the amount of knowledge possessed of the objects to be classified ; so that a group of genera which fifteen years ago were united into a family may now, by the addition of fresh genera, require subdividing into a group of families; and yet it may be convenient to retain as nearly as possible the original title for the whole group, though of course the patronymic termination must be altered.
Had the reviewer, however, been acquainted with Gerstiicker’s ‘Entomographien,’ he would have known that that author recognized two ‘groups, “zwei sehr ungleiche Gruppen ”—I. Endomychide genuini, I]. Endomychide adsciti.
Whether it is illogical to attempt the union of these, or unne- cessary to reconstruct the latter (which is a heterogeneous mis- cellany), I will leave to those who follow me to determine.
As your reviewer is so hard to please in the selection of names, he should at least have quoted correctly the one he terms awkward. I have no family “ Paussidoide,” but one Paussoideide.
The only genus in this family is T’rochoideus, Westw. Would he have thought Trochoideide less awkward or more expressive ?

On the Bermuda Humpbacked Whale of Dudley (Balena nodosa, Bonnaterre, Megaptera americana, Gray, and Megaptera bel- licosa, Cope). By Dr. J. KE. Gray, F.R.S. &c.
In the ‘ Proc. Amer. Phil. Soc.,’ October 1870, Mr. Cope describes the skeleton of a humpbacked whale as Megaptera bellicosa, sent from St. Bartholomew, West Indies, to Philadelphia, and figures the upper part of the skull and various parts of the skeleton. It agrees with the northern Megaptera longimana in having a scapula without any processes ; but differs in the form of the atlas vertebra, the nasals, and other parts of the skeleton. It is evidently a very distinct species.
The American whalers are now in the habit of catching hump- backed whales off the coast of San Domingo and in other parts of the Caribbean seas. “ Dr. A. Goés, of St. Bartholomew, says that the whales appear about the island of St. Bartholomew about the beginning of March, or even in February, and remain until the end of May. In April and May it is said that they are seen in pairs standing vertically in the water. When they return they often come in a family of three, male, female, and young (the calf one or two years old). The bull is wild and more difficult to take than the female, and he has on two occasions smashed the boat of his pursuers to pieces. In June they are said to go further into the Mexican Gulf, and return eastward in the autumn; but they do not appear among the smaller Antilles at that time. Dr. Goés supposes that they pass the Straits of Florida, or follow the shores of the south main. He says that the whalers think they pass the middle of winter on the African coast; but this will require con- firmation.”
This whale is no doubt the same as the “‘ Bunch or Humpbacked Whale ” of Dudley (noticed, with an account of the method of taking it, in the ‘ Philosophical Transactions’ for 1665), from Bermuda (where it livesfrom March to the end of May), on which Bonnaterre established Balena nodosa, and is the Megaptera americana of Gray, ‘Zool. Erebus and Terror, pp. 17 & 52, of which Megaptera bellicosa, Cope, will be a synonym.
By a curious perversity Mr. Cope refers to the Bahia finner, but makes no reference to or comparison with the Bermuda humpback, though Dudley and Dr. Goés say that they inhabit the Caribbean seas at the same period of the year.

Mr. Meldola attempted to test this theory by tabulating the state- ments of Mr. Edwards concerning the duration of the stages in the different polymorphic forms of Ajax ; and he found “ that there was a relationship, but exactly the reverse of that which would be anti- cipated from the conclusions previously set forth.”
The three forms of Ajax have been called by Mr. Edwards Walshii, Telamonides, and Marcellus; and these increase in size in regular ratio and succeed each other in season in this order. The following table represents the duration of the several stages, and is taken by Mr. Meldola from Mr. Edwards’s work :—

is directly instead of inversely proportional to the ratio of the pupal to the larval period, and vice versd.” Unfortunately for this con- clusion the figures given by Mr. Edwards, or their reduction by Mr. Meldola, refer in each case to the progeny of Walsh, Telamonides, and Marcellus, and do not bear upon the question ; in every instance given in the tables the progeny or resultant is Marcellus ; Walshii and Telamonides are the produce of wintering chrysalids, and there- fore by Mr. Meldola’s rule should be, as they are, smaller than Marcellus, which, on the other hand, is always the result of short- lived summering chrysalids. Unless, however, some unknown factor plays a part, Zelamonides should be smaller than Walshii, because produced later in the season from wintering chrysalids ; but here the opposite is the truth.
Mr. Edwards apparently overlooked the fact that Walshi and

Telamonides belonged to the same brood; the former consists of earlier, the latter of later individuals from wintering chrysalids ; the second brood of the species (the first from short-lived chrysalids) is Marcellus, and made up of the mingled progeny of both Walshi and Telamonides.—From an advance proof of the Proceedings of the Boston Society of Natural History, October 22, 1873.
The Habitat of Labaria hemispheerica. By Dr. J. E. Gray, F.R.S. &e.
In reply to Dr. Meyer’s communication at p. 66, I see I am wrong in not giving Cebu as the habitat of these sponges; but as I received the box of sponges some time after I received the letter containing their habitat, although he said I should receive the two together, I had forgotten that the one referred to the other. Iam astonished to observe that Dr. Meyer says, “ I obtained these sponges from the reefs in the sea near the village Talisay,” because the spe- cimen of Labaria we received had, when dried, separated into two parts—a hemispherical sponge and a long tuft of broken spicules of Euplectella, tied at one end by a strip of a spotted silk handkerchief, which had been affixed into the base of the hemisphere! Dr. Meyer, in a letter of November 6th, 1873, says, “I wondered to hear that the largest one proved to be artificially made up; if I am not mistaken, I got still some specimens of the same kind, but they did not yet arrive in Europe.” In a note just received (Jan. 21st) Dr. Meyer says :—‘I looked through those bottles and dried several sponges. My Malay boy from Ternate was charged with this business, and perhaps he may have tied something together or done another mischief with them ; or this may have been made by those fishermen at Talisay, I having overlooked it before I started, as I said, in a hurry.”
On the Steppe-Cat of Bokhara (Chaus caudatus). By Dr. J. E. Gray, F.R.S. &e.
The Zoological Department of the British Museum has lately re- ceived the skin and skull of a Chaus from the steppes of Bokhara. It is very lke the common jungle-cat (Felis chaus) from more southern Asia in the thickness and softness of the fur, in the general colouring, and in the tufts of the ears; but it differs from it in having a considerably longer tail, reaching nearly to the ground— hence its name Chaus caudatus in the description of it which has been read at the Zoological Society, illustrated by a beautiful figure by Mr. Wolf.

XXVII.—On the Structure called Eozoon canadense in the Laurentian Limestone of Canada. By H. J. CARTER, F.R.S. &e. (A letter to Professor W. Kina, Sc.D., Galway.)
My peEArR Srr,—On the 13th instant I had the pleasure to send you a‘ Card ”’ acknowledging the safe arrival of your letter of the 10th inst. and specimen of Laurentian Limestone contain- ing the so-called Hozoon canadense, intimating at the same time that after a few days I would answer you more at length. I now proceed to do so.
With the copy of your Papers* on the mineral origin of this formation (received on the 9th August last) and your present letter under reply, together with the decalcified slice of Laurentian Limestone (about 2x2x2 inch in size), which you state to be from Canada and to have been forwarded to your colleague Professor Rowney by Dr. Carpenter as a “typical specimen of Hozoon canadense,” I also possess in my own cabinet perhaps some of the most perfectly fossilized foraminiferous structure in existence; so that, for the purpose of comparing the two, I could not be more satisfactorily pro- vided.
That I should feel interested in the question at issue as to the identity of the Laurentian Limestone with that of fora- miniferous structure may be easily conceived by the accom-

190 Mr. H. J. Carter on “‘ Eozoon canadense.”’
panying copy of my paper on the “Form and Structure of Operculina arabica,” read before the Bombay Branch of the Royal Asiatic Society so far back as May 1852, and pub- lished in their Journal and in the ‘ Annals and Magazine of Natural History’ of the followiug year, together with many other papers subsequently published in the latter, from time to time, on the structure and adult forms of several fossilized Foraminifera, including new species. You may also thus fully understand how grateful I feel to you for having been the first to send me a specimen of the Laurentian rock, and to bring the subject of its structure and composition before me under the mineralogical point of view detailed in the papers published conjointly by yourself and Prof. Rowney, to which I have alluded.
You will also observe, by the figures in the plate attached to my paper on Operculina, that, at a very early period, I demonstrated the system of foraminiferous structure in a recent Operculina and identified it with the structure of a fossil Num- mulite. How much more completely than others, a comparison of our descriptions and illustrations respectively will show, it not being my business here to lay claim to any thing beyond a position to be able to compare genuine foraminiferous struc- ture, both living and fossilized, with the so-called Hozoon cana- dense.
Previously, however, to stating my observations in this respect, I would say a word or two on the law of form in organized beings; for this bears upon the subject.
That the “law” exists in the mineralogical as well as in the organic kingdom may be seen in the common mineral growth termed “dendrites.” But, besides this familiar example, it may be observed in what are called ‘“‘ moss-agates,’ coming from the geodes of trap—that is, from a volcanic rock. Of the latter I possess a polished and mounted specimen, composed of opalescent chalcedony, in which there is a growth of glauconite that, when viewed under an inch compound power, would, by any one not acquainted with the geological facts, be termed a “ branched Conferva.”
Again, I possess a similarly polished and mounted specimen of green calespar (that designated by Prof. Haughton “ Hislo- pite ”’), also from a trappean geode of Western India, in which there is a growth of glauconite so like the remains of dead incrusted Conferva from a dirty pond that, without being acquainted with its geological position, this would also be pro- nounced to be Conferva in such a state fossilized.
So far the ‘law of form” is the same in both kingdoms, and hence the necessity of knowing this before we state confi-
Mr. H. J. Carter on “ Eozoon canadense.”’ 191
dently that such and such forms are or are not organic. The mistake of identifying dendrites &c. with fossilized plants has often occurred, but not with acknowledged competent au- thorities.
Lastly, I possess a similar specimen of green Heulandite from the trap of Western India, in which the green colour is owing to the presence of a granular growth of glauconite among the translucent zeolithic mineral; and this brings me to the so-called Hozoon canadense, which you and your col- league Prof. Rowney conclude to be of a like nature, viz. granular serpentine in calespar.
With your mineralogical view I have nothing to do, as it would be presumption in me to even praise such high author- ities; but, from the fossilization point of view, I may be per- mitted to state facts which I feel able to appreciate in con- nexion with the subject.
Before, however, going to adult foraminiferous structure for comparison, it is desirable to premise its primary, which is its elementary, form.
Thus the assumed ovum of a foraminiferous animal is soft, spherical, filled with granuliferous sarcode, and nucleated while in the chambers of the adult living animal. After this, on approaching the embryonal state, the capsule becomes cal- careous and pierced all round with minute apertures, save at one point, where there is a large one, from which issues, in the living and active condition, the internal sarcode in the form of a short cord terminated by a reticulated lash of filaments (pseudopodia) of different lengths, which are ever changing in shape (Ameba-like) as they are put forth in search of food &e. The calcareous covering then becomes thickened, and the “ apertures ” elongated into tubes which, in juxtaposition, descend perpendicularly through the crust thus formed, and keep up a connexion between the exterior and interior of the embryo.
This is the elementary form or first chamber of a foramini ferous animal; and a repetition of it, produced by the sarcode which issues from the large aperture, thus goes on stolonifer- ously producing chamber after chamber, of the shape peculiar to the individual, until the increments thus produced at last arrive at the ultimate form of the species.
The soft ovum can only be seen in the recent animal; but the spherical embryos, both in my specimens of recent Oper- culina arabica and in the fossilized Nummulites &c., may be seen in abundance, not only in the chambers, but in the tubes (that is, in the branches of the stoloniferous prolongations of sarcode; for they also clothe themselves with a calcareous layer), on their way out from the chambers sy exterior.
192 Mr. H. J. Carter on “‘ Eozoon canadense.”’
In a specimen of Orbitolites which I possess the embryos (2 to 10 or more in most of the chambers) appear to be ellip- tical, almost like a Miliola!
Thus, as stated, the foraminiferous animal, built cell over cell, at length arrives at the specific form, whether Nummulite or Orbitoides &e., and throughout is but a repetition of the em- bryonal chamber modified only in shape to accord with the species. But still there are the tubuli perpendicular to the plane of growth in the crusts of the chambers respectively ; there are the chambers; and in the intervals of the general structure, which are filled up with calcareous material and thus form the skeleton, is a reticulated system of canals pro- duced by the branches of the stoloniferous sarcode, communi- cating in all directions with the chambers through their walls and with one another, finally opening on the exterior of the test, and in their course, as I have before stated, often pre- senting the spherical embryos in their transit from the chambers to the exterior ; while the tubuli of the crust of the chambers, being developed with these crusts successively as they are piled upon one another, form thus a cont/nuous communication, through the cavities of the chambers, between the exterior and very centre of the test.
Hence, if a section of a fossilized form be made just above or just below the chamber (that is, owés¢de it), the tubuli of the upper or lower part of the crust must be seen; while if it be made through the chamber, then the plane of the openings inside must be seen. Indeed it is impossible to make a section in which they do not come into view, or to examine a piece not larger than a small pin’s head without seeing them; so that to pretend to identify the acicular structure sometimes observed to be standing perpendicularly on, but much more frequently parallel with, the surface of the grains of serpen- tine in the Laurentian Limestone (which grains have been viewed as the casts of the chambers of a foraminiferous animal) with these tubuli, that always run directly to the chamber, and should be thus seen in almost every atom of foraminiferous structure, seems to me to be nonsense*.
Nothing can be clearer than all that I have above stated of foraminiferous structure, as seen under an inch-focus com- pound power in my infiltrated specimens of Nummulites, - Orbitoides, &c. from the Eocene formation of Western India.
But in vain do we seek in the so-called Hozoon canadense for the unvarying perpendicular tubuli, the s¢ne qué non of

foraminiferous structure. In vain do we look for that regularity of chamber-formation which, in the amorphous growth assigned to the so-called Hozoon, might be equally well assumed to be identical with the heterogeneous mass of chambers on each side of the central plane of Orbitoides dispansa, accompanied by the transverse bars of stoloniferous structure uniting one chamber to the other. In short, in vain do we look for the casts of true foraminiferous chambers at all in the grains of serpentine ; they, for the most part, are not subglobular, but subprismatic.
With such deficiencies I am at a loss to conceive how the so-called Hozoon canadense can be identified with foramini- ferous structure, except by the wildest conjecture; and then such identification no longer becomes of any scientific value.
Having examined the slice of Laurentian Limestone which you have so courteously submitted to me in thick and thin polished sections mounted in Canada balsam, by transmitted and also by reflected light, also the surface of the “‘ decalcified ” slice as it came from you, in all directions with 3- and 1-inch focus compound powers respectively, I must unhesitatingly declare that it presents no foraminiferous structure anywhere. Nor does its structure bear so much resemblance to that of a foraminiferous test as the legs of a table to those of a quadruped ; while if such be the grounds on which geological inferences are established, the sooner they are abandoned the better for geology, the worse for sensationalism !
The contents of this letter are open to no controversy. My knowledge of foraminiferous structure has been obtained step by step, beginning with the recent and then going to the fossilized forms, making and mounting my own sections, from which afterwards my illustrations and descriptions have been taken. If others who have pursued a similar course of in- struction differ from me in what I have above stated, the ques- tion can only be decided by a third party, not on verbal arguments alone, but on a comparison of the actual specimens, as prolonged disputation, in matters of opinion, soon disgusts every body but the combatants, and can end in nothing but a fearful waste of time that might be better employed. The accompanying slide I must ask you kindly to return at your convenience, as, you will admit, such specimens of foraminife- rous structure are not so plentiful as Laurentian Limestone !

XX VIIL.— Observations on Cheetetes tumidus, Phillips. By R. Eruerrpce, Jun., F.G.S.
[Plate XI, figs, 1-3.]
CHZTETES TUMIDUS was first described by Prof. Phillips in 1836 under the name of Calamopora tumida* ; but although several figures were given, a very limited description was appended. As Favosites tumida both Portlock t and M‘Coy} noticed this coral and gave short descriptions of it. It was also recorded under the same name in the early edition of Morris’s ‘Catalogue’§. In his great work the ‘British Paleozoic Fossils’ M‘Coy added to and more clearly defined the characters of this coral as Stenopora tumida||; he there notices the characters of the tubes or calices, the nature of the diaphragms or tabule, and indicates the presence of a con- cave diaphragm nearly closing each of the tubular openings. Messrs. Milne-Edwards and Haime appear to have been the first to refer the Calamopora tumida of Phillips to the genus Cheetetes 4]. Although they do not mention the existence of tabule in their description, yet such appear to be plainly in- dicated in figure 3a, plate xlv., of their ‘ British Fossil Corals.’ Lastly Prof. De Koninck, in a recently issued work **, has given an interesting recapitulation of the principal points in the structure and history of this species, under the name of Monticulipora tumida.
The majority of specimens obtained from Scotch carbonife- rous beds, in some of which the species is very plentiful, have the margins of the calices apparently more thickened than is generally represented, although this character is variable even on the same specimen. ‘The calices are in places very un- equally developed, giving rise to spaces every here and there more or less free from openings, or where the latter are much smaller than the generality of those on the same specimen, thus forming spots which to the naked eye appear like plain patches (Pl. XI. fig. 1,a). The smaller tubes are about one fourth the size of the larger. On the base of attachment of Cheetetes tumidus the tube-openings are often of a more irregular form than on the branches, becoming oval, and the walls not

so thickened. This is probably the fossil figured by Ure in his ‘ History of Rutherglen and E. Kilbride’*, and described by Fleming as Cellepora Uriit. If this is so, Ure was the first to figure Chetetes tumidus; and it, like many of his figures, is very faithfully drawn.
When decorticated the tube-walls of C. tumidus are con- siderably reduced in thickness, when compared with the thickened external surfaces.
Fig. 2 represents a vertical microscopic section of a portion of a branch, where in the central portion, as has been pointed out by M‘Coy f, the tubes are vertical and abruptly diverge to the surface, where they open at right angles. ‘The internal wall of each is circular, the external hexagonal or polygonal, becoming thinner towards the imaginary axis of the coral. The vertical portion of the tubes in a transverse section presents the appearance of an axis of cellular tissue (fig. 3).
Both M‘Coy and Edwards and Haime indicate the existence of tabule. The former says, “ diaphragms about the diameter of the tubes apart’’§; the latter do not mention these structures, but they distinctly figure them ||. On the other hand, Prof. De Koninck, in his description of Monticulipora tumida, states that although he had examined numerous Irish and Belgian specimens, yet he had failed to discover any trace of tabul (planchers). In fig. 3, which is a transverse section of fig. 2, the tabule may be distinctly seen as delicate lines in that por- tion of the tubes at right angles to the general axis, at which point the walls in some specimens appear to be more or less constricted.

[Plate XI. figs. 4-14. ]
THE region in which the invertebrate marine animals cited in the following Catalogue were collected by Dr. Pansch, between the shore line and a depth of 30 fathoms, extends from 73° 50! to 75° 15' N. lat. Here the animals live in a temperature which varies but little throughout the year. According to the log- book of the ‘ Germania,’ Captain Koldeway, the daily average of the surface-temperature from the 9th of July to the 13th of September 1869, from 70° 44’ to 75° 30! N. lat., only oscillated between 1°62 and 1°29 R. (=35°-64 and 34°9 F.). Then ice was produced, beneath which, from the 3rd of October 1869 to the 21st of May 1870, a temperature of 1°5-2° R. (=35°4 -36°°5 F.) prevailed. Measurements of temperature down to 220 fathoms within the same latitudes between the 13th of July and the 3rd of August 1869 gave 0°4-1°3 R. ( =32°:9-34°-92 F.).
In the year 1870 the surface temperature between 71° 20! and 75°26’ N. lat. from the 11th of July to the 28th of September was found to be 0°:02—4°'62 R. (=32°-045-42°'4 F.). Between 73° 11! and 71°30! from the 12th of August to the 27th of September, at depths of 20-300 fathoms, 0°-7—2°°6 R. ( =33°°57-37°°85 F.) were observed.
According to the log-book of the ‘ Hansa,’ Captain Hege- mann, 1°-0°°6 R. (=34°:25-33°°35 F.) were found at 20-75 fathoms, on the 14th and 15th of July, in N. lat. 74°37! and 74° 57’; and 1°R. (34°25 F.) at 100 fathoms in N. lat. 73° 5’.
In his address upon the scientific results of the first German North-Polar voyage of 1868, M. von Freeden says (p. 4) :— “ Beyond the parallel of Jan Mayen (71° N. lat.) as far as 77° we find a great sea-surface which, from the 1st of June to the ist of September, possesses a temperature oscillating between 0° and 2° R. (=32° and 36°°5 F.), and which is more and more filled with melting masses of ice the further west we go.”
Thus, with regard to the oscillations of temperature in their medium, the marine animals of Greenland are in just as favour- able a position as the animals of the tropical seas.
According to Dana’s ‘Classification and Geographical Distri- bution of the Crustacea,’ 1853, p. 1483, the mean surface- temperatures of the thirty coldest and the thirty warmest con- secutive days are as follows :—near

From the temperature-observations made by Prof. Carl Semper in the sea surrounding the Philippines, which he has been kind enough to place at my disposal for these com- parisons, I extract the following :-—
On the 26th of June 1861, near Anhuplate, between 10 o'clock in the morning and 10 o’clock in the evening,
the temperature of the air varied between 20°°6 & 22°-9 R. (=78°35 & 83°°5 F.), the temperature of the surface varied between 21°3 & 21°8 R. (=79°-9 & 81°-05 F.). At the same place on the same day the temperature at 5 fathoms was 21°-5 R. (=80°4 F.) at 10 a.m.
17 3 21°-4 R. (=80°15 F.) at 2:30 p.m. 22 5 "21°-4 R. (= 80°15 F.) at 3 pm. 5 3 21°°5 R (=80°4 FE.) at 5 p.m.
Thus, at the depths here cited, the temperature differs very little from that of the surface, just as in the northern icy sea.
I suppose that the nearly uniform temperature in which the high-northern marine animals live is one of the chief causes of the considerable size by which, according to numerous observa- tions, they are distinguished from individuals of the same species in temperate regions ; for, at the bottom of the icy sea, species which from their nature can thrive in a low tempera- ture are but little if at all exposed to those disturbances which the greater oscillations of temperature produce in the vital con- ditions of the animals of more temperate seas. ‘The organs can consequently perform their functions in a more uniform manner (so far as these are dependent on temperature) than in indi- viduals of the same species which inhabit, for example, the middle and higher regions of the North Sea and the Baltic, where the differences between the lowest and highest tempera- tures of the water amount to 10°-15° R. (=22°-5-33°75 F.), or sometimes even more, as has been ascertained by H. A. Meyer * for various points in the western basin of the Baltie, and by myself for two places in the North Sea off the German coast T.

becomes nearly cylindrical. Head somewhat narrowed in front (Pl. XI. fig. 4). In front, on the cephalic lobes, there are two small round projections. ‘I'wo eyes, on two flat cushions, which become fused together behind and run out into a single flat and narrow cushion, extending as far as the fourth body- segment.
Buccal orifice bounded to the right and left by pad-like lips, which unite below at an acute angle (fig. 5).
The first body-segment bears two tufts of sete, which are smaller than those on the three following segments. The sete of the upper tufts of the fore body (in front of the fifth segment) are subulate, those of the lower tufts narrowly lanceolate (figs. 9& 10). On the fifth segment there is, both above and below the thick sete, a small tuft of fine sete (figs. 11 & 12).
From the sixth segment onwards there are on the ventral surface uncini, five or six in each row; they are slightly sigmoid and two-pointed (fig. 8). The sete of the dorsal surface stand upon the anterior surface of small tubercles ; and behind these are the branchiz, which only become long enough to be called linguliform from the tenth segment onwards. They are longest on the seventeenth segment. In front of the longer branchie the setigerous tubercles are smaller than before the shorter ones. Each branchia contains a simple vascular loop without anastomoses.
From the eighteenth segment onwards there are on the sides of the body, lower down than the branchiz, and at the boundary between each two segments, some tubercles, which posteriorly become racemose. ‘These are egg-racemes or external ovaries (figs. 6& 7), with ova not yet fully developed (fig. 14). On the imner surface of the body-wall there are elongated ova (fig. 13) in the same segments of the body which bear external ovaries.
Unfortunately only one example of this worm was found. It is brownish yellow (in spirit), and has on the middle of the hinder part of the back two brown longitudinal lines, which are thickened parts of the cuticle.
I place this new genus among the Spioide’. It has no cephalic appendages like Prionospio, Malmgr., possesses lingu- liform branchiz with a simple vascular loop, like Spzo, Fab., and has a comb-like series of thick setee in the fifth body- segment, like Polydora, Busk (Leucodore, Johnst.).
The formation of the ova in external ovaries is a phenomenon not previously observed among the Annelides.

Class HY DROZOA.
The Hydroid Zoophytes of St. Andrews are chiefly pro- cured from the deep water of the bay, though a few appear between tide-marks. Many are found in great profusion. Contrasted with the southern shores, as at Devon and Corn- wall *, the majority of the Hydroids are equally common in both localities ; some occur more frequently in the one than in the other, while a third series is more characteristic of each area. Thus Sertularella rugosa, Sertularia cupressina, Thuiaria thuja, and Halecitum muricatum appear to be more abundant at St. Andrews than in the south; on the other hand, Sertularia argentea and Obelia dichotoma are probably more plentiful in the latter, together with the appearance of Tubularia at the extreme margin of low water. The cha- racteristic forms in the south are Corymorpha nutans, Aglao- phenia pluma, A. pennatula, Ophiodes mirabilis, Diphasia pinnata, and an abundance of the species of Plumularia. At St. Andrews Sertularia filicula, S. fusca, Tubularia coronata, Cuspidella humilis, and Halecium labrosum afford distin- guishing features. Moreover, instead of the tufted Clava squamata, so common on the littoral Fuci of the western coast, we have OC. multicornis at St. Andrews on the under surface of stones ; the splendid Corymorpha nutans of the sandy voes, and the rich tufts of littoral Corynide and G'onothyrwe of the Zetlandic region, are likewise wholly absent. Amongst the Hydromeduse, Sarsia prolifera, Forbes, occurs occasionally, and Thaumantias pilosella, Forbes, in great abundance on the surface of the bay in autumn.
The habit of the zoophytes affords many interesting facts, especially in regard to the profusion of parasitic structures. The roots of the polyparies spring from diverse shells, stones, crabs, submerged sticks and branches. One of the most curious examples found by the fishermen in the bay consisted of a stout branch of a thorn-tree, about four feet in height, which had large specimens of Balanus Hameri and Ascidians clustered like living fruit on the main trunk and branches,

and lobulated and club-shaped masses of A/eyonium coating the more slender twigs and overrunning the neighbouring Cirri- pedes; while Obelia fringed most of the branches, here and there giving place to the shorter coating of Sertularia, stunted Tubularia, or the downy Clytia. Hosts of other animals occurred on the congenial site—tubes of Thelepus and Serpula, Anomia, Saxicava, Xylophaga, Lepralia, Cellepora, and Tubu- lipora representing the sedentary forms, sessile-eyed Crusta- ceans and Starfishes the free. Indeed the production tormed a compendium of marine zoology that took much time and trouble to investigate. The rapidity of growth of the larger specimens (the Balani being as large as walnuts) was shown by the condition of the wood and bark, and the presence of many delicate twigs. ‘This is also seen in the case of slender branches of the common currant-bushes, which are brought to land in good preservation yet densely fringed with Obelia longissima and studded with large ascidians. The zoophytes themselves are subject to many parasitic inroads from sponges, Foraminifera, other zoophytes, various Polyzoa, Ascidians, Nudibranchs and their ova, young mussels and Anomie, the ova of Pycnogonum, Annelids and their tubes (hyaline, gritty, and calcareous), and minute Cirripedes.
In the following list the arrangement and nomenclature of the Rey. T. Hincks in his recent beautiful work on the Hydroida is adopted,
Order I. HyprorIpa, Suborder I. ATHECATA. Fam. 1. Clavide.
Genus CLAVA, Gmelin. Clava multicornis, Forskal ; Hincks, Brit. Hydroid Zoophytes, vol. i. p. 2.
Frequent under stones in pools near low-water mark, and growing on Cynthia grossularia under the cavern roofs ; but it is not seen on the littoral seaweeds, as is Clava squamata on the shores of the Hebrides and the western and other coasts of Scotland. The tentacles show a slightly enlarged sucker- tip.
Fam. 2. Hydractiniide.
Genus Hypractinia, Van Beneden. Hydractinia echinata, Fleming ; Hincks, Brit. H. Z. vol.i. p. 23.
Abundant on Fusus islandicus, Natica, and other univalve Ann. & Mag. N. H. Ser. 4. Vol. xiii. 15

shells cast on shore after storms. The outer lip in the shells inhabited by hermit crabs is frequently prolonged into a horny membrane, as mentioned by Dr. Johnston.
Fam. 9. Eudendriide. Genus EupENprIvUM, Ehrenberg. Eudendrium rameum, Pallas ; Hincks, Brit. H. Z. vol. 1. p. 80. Plentiful in the deep water of the bay, attached to shells and masses of Balani and Serpule. A fine specimen measured
9 inches high, and the breadth of the branched portion was 8 inches.
Eudendrium capillare, Alder; Hincks, Brit. H. Z. vol. 1. p. 84.
Fine tufts are occasionally found on the stems of Anten- nularia ramosa, interwoven with other zoophytes, from deep water. The specimens had no short branches ; all were much elongated, and the polyps terminal. Some slight rings existed here and there on the main stems at the base; those at the origin of each branch are very distinct.
Fam. 11. Tubulariide. Genus TuBULARIA, Linneus. Tubularia indivisa, L.; Hincks, Brit. H. Z. Vol-1..p.. 115.
Common in deep water. One of the largest specimens springs from an agglutinated basis of the valves of Pecten opercularis and gravel, eight inches in diameter, and the gigantic tuft had tubes 11 inchesin height. It also sometimes fixes the valves of a living Mytilus modiolus so as almost to prevent motion.
Tubularia coronata, Abildgaard ; Hincks, Brit. H. Z. vol. i. p. 119. Abundant in deep water. I am obliged to Prof. Allman for discriminating wrinkled specimens of this species, in 1863. Suborder I]. THECAPHORA. Fam. 1. Campanulariide. Genus CrytrA, Lamouroux. Clytia Johnston, Alder; Hincks, Brit. H. Z. vol. i. p. 143.
Abundant on Alcyonidium hirsutum and seaweeds in the
Dr. W. C. M‘Intosh on the Zoophytes of St. Andrews. 207
pools near low-water mark, as well as coating the stems of Laminarie with a hairy fringe fully half an inch in height. In a fine example of the latter many of the stems possess one or two branches, and the gonothece here and there have a stalk composed of several rings.
Genus OBELIA, Péron & Lesueur.
Obelia geniculata, L.; Hincks, Brit. H. Z. vol. i. p. 149.
Common on laminarian blades thrown on the West Sands after storms, forming a miniature cover amidst which many Nudibranchs find food and shelter. It occurs plentifully also on Halidrys siliquosa and other seaweeds near low-water mark, and on crabs. Inthe interior of many of the gonothece are the young of a Pycnogonidian.
Obelia longissima, Pallas ; Hincks, Brit. H. Z. vol. 1. p. 154.
Abundant in deep water. It bristles on every branch or fragment of wood which has been submerged for some weeks, It appears also in a very interesting condition in the peculiar rounded balls formed by the rolling action of the waves on the beach; these zoophytic masses are either spherical or rounded-oblong, and the fibres are firmly felted together *. In this state the present species is stripped of its minute branches, and feels bristly and crisp. The same rolled masses (also chiefly composed of an Odelia allied to the present form) were brought from the shore of a New-Zealand bay by Dr. Lauder Lindsay, who kindly sent them to me. They are formed in a similar manner as the well-known balls in Loch Tay, where the rolling action of the waves produces perfectly round masses, often as large asa spherical shot of thirty or forty pounds, com- posed of the linear leaves of the larches and pines which shade its margin. Miss M‘Leod, of Paible, brought me spherical masses of a similar description from a freshwater lake in South Uist, the species in this case, according to Prof. Dickie, being Cladophora glomerata. O. longissima affords a favourite site for young mussels.
Obelia dichotoma, L.; Hincks, Brit. H. Z. vol. i. p. 156.
Not common ; parasitical upon a piece of seaweed from the laminarian region, and reaching about 3 inches high.
* One of these masses so closely resembled the chignon lately in vogue that it was secretly used by a patient for this purpose, and I learned that it was only the disagreeable abundance of maid in its tissue that saved it from further duty in this respect. _

Genus CAMPANULARIA, Lamarck.
Campanularia volubilis, L.; Hincks, Brit. H. Z. vol. i. p. 160.
Common; on crabs, the stems of Sertularia argentea and other zoophytes from deep water. It is a smaller and more delicate species than C. verticillata. The shape of the cup and the very distinct “spherical ring” below distinguish it when the gonothece are absent.
Campanularia Hincksii, Alder ; Hincks, Brit. H. Z. vol.i.p. 162.
Occasionally found on the stems of Antennularia antennina from the deep water of the bay. This species presents certain variations. In some the stem is nearly smooth from the base to the cup, where there are only a few slight twists ; in others there are several distinct though irregular rings or twists at the base, a few about the middle of the stem, and others at the base of the calycle; in almost all there is one very distinct ring at the base of the latter, as Mr. Alder shows in his figure *. There is also a peculiar hollow at the base of the calycle ; but this cannot be called a ring.
Campanularia verticillata, L.; Hincks, Brit. H. Z. vol. 1. Dealowe
Common in deep water. Many specimens were also found in the stomach of Echinus esculentus from the laminarian zone.
Campanularia flexuosa, Hincks, Brit. H. Z. vol. 1. p. 168.
Not uncommon on the under surfaces of stones near low- water mark. The peculiar zigzag form of the stem, with the arms of the forks tending in opposite directions, together with the short, broad, and smooth-edged hydrothecz, are character- istic. The long pedicels of the hydrothece had their central smooth portions peculiarly flattened out, so as almost to assume a fusiform aspect.
Campanularia raridentata, Alder; Hincks, Brit. H. Z. vol. 1. p. 176.
Occasionally found on Antennularia antennina and other zoophytes from the coralline ground. The form agrees in most respects with the published description. The calycle is very narrow and deep, with six to eight large teeth on the margin ;
* Catalogue of the Zoophytes of Northumberland and Durham, pl. ii. fig. 9.
Dr. W.C. M‘Intosh on the Zoophytes of St. Andrews. 209
stalk rather slender (much more so than in Clytia Johnston‘), with several distinct rings below the cup, and many less distinct towards the base. The peculiar slenderness of the stalk, the length of the cup, and the small number of teeth are the characteristic features. Specimens which resemble Clytia Johnstoni occasionally grow in proximity ; and some interme- diate forms occur.
Genus GONOTHYR&A, Allman.
Gonothyrea Lovént, Allman; Hincks, Brit. H. Z. wol.i.cp. 188.
Abundant on Sertularia abietina and Diphasia rosacea from deep water. The exceeding delicacy of the free margins of the hydrothece, even in good spirit-preparations, renders it difficult to say whether they are (or were) notched or smooth. It was only by a comparison of observations on many examples that the peculiar crenations were understood, as none showed more than a few, and the majority none at all. The appear- ance of the gonothecz, however, is characteristic.
Gonothyrea gracilis, Sars; Hincks, Brit. H. Z. vol. i. p. 183.
Plentiful on Tubularia indivisa, from deep water, amongst Clytia Johnstoni, on the tests of Ascidia sordida, on Scalpellum vulgare, Stenorhynchus rostratus, and Cellepora pumicosa. The capsules are large, translucent, and borne on a ringed stalk. Growing as this did amongst C. Johnstont, it at first seemed to be a branched variety of the latter ; but the peculiar nature of the branching and the structure of the gonothece, which were chiefly borne on the stems, distinguished it on closer scrutiny. Moreover the hydrothece of this species, contrasted with C. Johnstont, are much larger and deeper.
Fam, 2. Campanulinide.
Genus OPERCULARELLA, Hincks.
Opercularella lacerata, Johnston; Hincks, Brit. H. Z. vol.i. p. 194.
Abundant on the stems of Plumularia pinnata, Obelia lon- gissima, and other zoophytes, and amongst Clytia Johnstoni on the stems of Laminarve; Prof. John Reid also found it on Scrupocellaria scruposa. This species presents two well- marked varieties, which occur together on the same stem: (a) hydrothece on simple stalks of variable length, viz. from three to nine rings; and (4) branched stems of some height, with the alternate stalks of the hydrothece composed of from
210 Dr. W.C. M‘Intosh on the Zoophytes of St. Andrews.
six to more than a dozen rings. Moreover, in these branched forms it is not uncommon to see more than one pedicel arise at the same fork, so as to cause the observer to fancy he is viewing the Campanulina turrita of Prof. Wyville Thomson ; only the hydrothecee are much shorter in proportion to the length of the teeth. Some examples on a laminarian stalk had very long stems. The hydrothece in all very closely resembled those on Dr. Allman’s Campanulina repens (Hincks, Brit. H. Z. vol. i. p. 189, pl. xxxviii. fig. 1).. No gonothece were observed.
Fam. 4. Lafoeide.
Genus Laroza, Lamouroux.
Lafoéa dumosa, Fleming ; Hincks, Brit. H. Z. vol. 1. p. 200.
Common on various zoophytes from deep water. Some varieties of this species have short stalks of one or two whorls supporting the hydrothece ; but they are not quite so long as those described under L. fruticosa, Sars, and the intermediate forms show that they are to be referred to the present species.
Lafoéa fruticosa, Sars; Hincks, Brit. H. Z. vol. i. p. 203.
Occasionally on zoophytes from deep water, especially Ser- tularia filicula. The pedicels of the hydrothece have from three to five rings.
Besides the above there are several microscopic forms closely allied, which creep along the stems of various zoophytes. A sessile form is common on Crista eburnea, and astalked species on Scrupocellaria scruposa.
Genus CALYCELLA, Hincks. Calycella syringa, L.; Hincks, Brit. H. Z. vol. i. p. 206.
Abundant on the stems of Hydrallmania falcata and other zoophytes from deep water.
Genus CuspIpELLA, Hincks. Cuspidella humilis, Hincks, Brit. H. Z. vol. i. p. 209.
Not uncommon on the tests of Ascidia sordida, and on the valves of Psammobia and other shells, from deep water. The tests of Ascidians are the seat of a reticulated growth with numerous minute club-shaped processes rising from the creeping stem which is associated with C. humilis.
Dr. W. C. M‘Intosh on the Zoophytes of St. Andrews. 211
Genus FILELLUM, Hincks.
Filellum serpens, Hassall; Hincks, Brit. H. Z. vol. 1. p. 214.
Abundant on the stems of Sertularia abietina and H. falcata from deep water.
Fam. 6. Coppiniide. Genus CopprniA, Hassall. Coppinia arcta, Dalyell; Hincks, Brit. H. Z. vol.1. p. 218.
Common on the stems and branches of Sertularia abietina and Hydrallmania falcata.
Fam. 7. Haleciide. Genus HAtecium, Oken.
Halecium halecinum, L.; Hincks, Brit. H. Z. vol. i. p. 221.
Plentiful in deep water, though somewhat less common than the next species. Young specimens under an inch in height sometimes occur, which in spirit quite agree with the Rey. A. M. Norman’s description of H. sess¢le (Hincks, 1. c. p. 229, pl. xliv. fig. 2), with, of course, the exception of the polyps. In these cases the hydrothecze do not seem to be fully developed; but they show the row otf dots below the margin. Specimens are also seen in which one or two of the hydrothece are better developed at the base of the stem, while all the rest are in the condition described by Mr. Norman. It would appear to be doubtful if the mere elongation of the polyps would constitute specific distinction, any more than the fact that the branches are not in the same plane. Some are slightly ringed.
Halecium muricatum, Ellis and Solander; Hincks, Brit. H. Z. vol. 1. p. 223. This is the common Haleciwm from the deep water of the bay. Most of the specimens show a ring or two on the stem above the calycles.
Halecium Beanii, Johnston ; Hincks, Brit. H. Z. vol. i. p. 224.
Not uncommon in the coralline region, attached to other zoophytes and to the tests of Ascidians. Young examples have piles of little cups on the hydrothecee like those on the beautiful southern H. tenellum, Hincks.
Halecium labrosum, Alder; Hincks, Brit. H. Z. vol. i. p. 225.
From the deep-sea lines of the fishermen. Mather rare.
212 Dr. W.C. M‘Intosh on the Zoophytes of St. Andrews.
Fam. 8. Sertulariide. Genus SERTULARELLA, Gray.
Sertularella polyzonias, L.; Hincks, Brit. H. Z. vol. i. p- 235.
Abundant in the deep water of the bay, generally attached to the roots of other corallines. All the specimens seem true to the description of the species; at least there is no tendency to wrinkles in the hydrothece so far as examined.
Sertularella rugosa, L.; Hincks, Brit. H. Z. vol. i. p. 241.
Common; under stones near low-water mark, and thence to deep water, on seaweeds, Flustra foliacea, &c.
Sertularella tenella, Alder; Hincks, Brit. H. Z. vol. i. p. 242.
In profusion on Sertularia abietina and other zoophytes from the coralline ground.
Genus DipHAsIA, Agassiz.
Diphasia rosacea, L.; Hincks, Brit. H. Z. vol. i. p. 245.
Abundant in deep water on other corallines, such as Hydr- allmania falcata, Thuiaria thuja, Halecium, &c. The speci- mens are large and luxuriant. Mr. Hincks is right in stating that the male gonothece have eight longitudinal ridges, and not six as Dr. Allman says.
Diphasia tamarisca, L.; Hincks, Brit. H. Z. vol. i. p. 254. Not uncommon in deep water attached to shells and stones.
Genus SERTULARIA, Linn.
Sertularia pumila, L.; Hincks, Brit. H. Z. vol. i. p. 260.
This is the common Sertularian under stones in rock-pools at and near low-water mark at St. Andrews; but it is less luxuriant than on the Fuci of the western coasts. It forms a miniature forest on the under surface of the stones in quiet places, and is a favourite haunt of Holds viridis and other Nudibranchs. It presents the peculiarity in such situations that the stem is not always contracted above the hydrothece, but not unfrequently these follow each other without the con- striction. In some preserved specimens the hydrothece con- tained a number of large nucleated cells, having apparently a thickened. and regularly crenated cell-wall ; these cells varied in size; and some also occurred in the centre of the stem.
Dr. W. C. M‘Intosh on the Zoophytes of St. Andrews. 213
Sertularia operculata, L.; Hincks, Brit. H. Z. vol. i. p. 263.
Not uncommon; on seaweeds at and beyond low-water mark, but chiefly procured on the West Sands after storms. Its comparative scarcity is in marked contrast with its profu- sion on our western coasts, where almost every laminarian root and stalk are clothed with dense tufts.
Sertularia filicula, Ellis and Solander; Hincks, Brit. H. Z. vol. i. p. 264.
This, perhaps, is the most abundant Sertularian next to S. abietina from deep water. Dried specimens, when carefully laid out, show a somewhat rectangular arrangement of their terminal branches. Good examples have also been procured from the stomach of the cod.
Sertularia abietina, L.; Hincks, Brit. H. Z. vol. i. p. 266.
Very common; and occasionally reaching the height of 9 inches ; fine tufts occur on Mytilus modiolus. This species is a favourite seat of many parasites, such as other hydroid zoophytes, calcareous corallines, Spirorbis, Alcyonidium, Coppinia, &e. Fyrom its attachment to living mollusca (Anomia and others) it is not unfrequently swallowed by the cod.
Sertularia argentea, Ellis and Solander; Hincks, Brit. H. Z. vol. i. p. 268.
Not common; from the deep-sea lines of the fishermen. This seems to be a form more characteristic of our southern shores.
Sertularia cupressina, L.; Hincks, Brit. H. Z. vol. i. p. 270.
Very plentiful in the coralline region, and sometimes reaching the length of 18 inches. Besides the ordinary form there are two branched varieties. In the first, numerous secondary poly- paries spring from the ordinary dichotomous branches, each twig so burdened being very little thicker than the ordinary forms, and bearing in the usual manner for some distance the hydrothecee, which gradually become obsolete ; this secondary trunk assumes considerable dimensions, with jointed stem and dichotomous branches, like an independent specimen. In the other variety the main stem itself splits into two divisions, or the secondary trunks throughout are directly connected there- with.
Sertularia fusca, Johnst.; Hincks, Brit. H. Z. vol. i. p. 272. A single fine specimen only has yet been procured, in the
214 Dr. W. C. M‘Intosh on the Zoophytes of St. Andrews.
deep water of the bay. Mr. Alder correctly observes that this form leads us to Thucaria.
Genus HypRALLMANIA, Hincks.
Hydrallmania falcata, Li. ; Hincks, Brit. H. Z. vol. i. p. 278.
One of the most abundant hydroid zoophytes from the coral- line ground. Its form varies from the elongated spiral to the broadly branched condition, and it is frequently loaded with parasitic zoophytes, both horny and calcareous. It is also a favourite site for Nudibranchiate Mollusca and their ova, and minute Annelids construct their tubes on every convenient bough. Young specimens are plentiful also under stones between tide-marks, where their habit differs considerably from the foregoing, having the form of a simple straight pinna, generally coated with parasitic structures, both animal and vegetable.
Genus THurARIA, I'leming. Thutaria thuja, L.; Hincks, Brit. H. Z. vol. i. p. 275.
Common; chiefly frequenting dead valves of Cyprina, Pecten, and Tapes, as well as stones, shooting its long stems upwards (occasionally to the length of 14 inches) amidst masses of the tubes of Serpula, Thelepus, and other Annelids, and patches of Aleyonium. In some examples a short secondary stem branches from the main trunk near the base. Parasitic upon the stems are numerous other corallines, such as Diphasia rosacea, Which clothes anew the bare zigzag trunk with a more silky fringe than nature originally provided ; rough crusts of Cellepora or the spreading Alcyonium and Alcyonidium entirely surround it; while occasionally a long tunnel of Thelepus is glued from the base to the branching portion. Now and then it occurs in the stomach of the cod.
Fam. 9. Plumulariide. Genus ANTENNULARIA, Lamarck. Antennularia antennina, L.; Hincks, Brit. H. Z. vol. i. p. 280.
From the deep water of the bay ; common, but less so than the next species. Fine tufts reach a height of fully 11 inches. In a curious example a number of simple straight stems pro- ceed from the upper edge of a fragment of an old trunk.
Antennularia ramosa, Lamarck; Hincks, Brit. H. Z. vol. 1. p. 282. Common in deep water, whence it is usually brought by the fishermen’s lines.

Genus PLuMULARIA, Lamarck.
Plumularia pinnata, L.; Hincks, Brit. H. Z. vol. i. p. 295.
Frequent in deep water, and often reaching the height of 7 inches. A tall variety is found in which no spines are present on the gonothece. It sometimes occurs on Stenorhynchus rostratus between tide-marks.
Plumularia catharina, Johnst.; Hincks, Brit. H. Z. vol. i. p. 299.
Common on Ascidians, tubes of Thelepus, and the roots of other corallines in deep water.
Plumularia frutescens, Ellis & Solander; Hincks, Brit. H. Z. vol. 1. p. 307.
Occasionally thrown on the West Sands after storms, and also brought in on the deep-sea lines of the fishermen. The smaller specimens are pale. One example is 6 inches in
height, and broadly branched.
Order MEDUSID&.
The Meduside abound chiefly in autumn in the bay, the most conspicuous amongst the larger forms being Awrelia and Cyanea, the former often occurring in such numbers as to form a closely packed layer on the surface of the sea over considerable areas; and though not in the dense party-coloured masses of various species occasionally seen in the Hebrides, still they form an interesting feature. At certain points the bay in quiet weather is quite purplish with thousands, many of which are loaded with ova; and through the transparent umbrellas the abdominal feet of the parasitic Hyperide are observed in con- stant vibration. Occasionally, whether from accident or de- sign, one specimen is found adhering to the umbrella of another, and is thus.carried through the water. Moreover,on many of the stones at the East and West Rocks, near low-water mark, a “Hydra tuba” is found, which may be the hydroid condition of the foregoing. This pretty little white structure, developed from the ova of Awrelia and its allies, can be observed in all stages not only throwing out lateral buds like a Hydra, but by transverse fission dividing into a series of saucer-shaped bodies which ultimately assume the form of the adult Aurelia. This form, it is well known, formed the subject of valuable observations by the late Prof. M. Sars, and afterwards, amongst
216 Dr. W.C. M‘Intosh on the Zoophytes of St. Andrews.
others, ‘by the late Dr. John Reid, who obtained his examples at St. Andrews.
On the whole we lack at St. Andrews the splendid profusion of the swimming jellies occasionally met with on our western shores, and especially in the Outer Hebrides, to which a favouring wind and tide sweep them from the warmer area of the Gulf-stream beyond, in company with Janthina and the Pteropods. Amongst these the strange and beautifully tinted Diphyes is seen darting hither and thither amongst the brillant blues of its brethren with its trailing fringes of bright orange polypites ; and on the lonely western shores, as at Monach, countless myriads of the little Vele//a are tossed in autumn on the sand.
Mr. Darwin *, referring to the colours of certain Invertebrate animals, thinks that itis doubtful if such serve as a protection ; but he goes on to observe that the perfect transparency of the Meduse, ‘‘ many floating mollusca, crustacea, and even small oceanic fishes partake of this same glass-like structure,” and that ‘‘ we can hardly doubt that they thus escape the notice of pelagic birds and other enemies.’ It seems to me somewhat difficult to say what will escape the eye of a pelagic bird, such as gull, guillemot, or hawk-like tern. ‘Their keen eyes distinguish very indistinct objects—for instance, the nucleus of Salpa runcinata, and the minute and almost transparent bodies of the young fishes that flit amongst the splendid masses of swimming jellies (Molluscan and Ccelenterate) which some- times throng our western shores. The mere tremor of the water is almost sufficient to attract such acute and skilful marauders. Moreover, the statement of the great naturalist is incomplete without the appendix that many of the Meduse and Hydromeduse are brilliantly coloured and, in addition, phosphorescent, the latter property likewise characterizing the translucent Pyrosoma, and that my distinguished friend Prof. Wyville Thomson regards the luminosity of marine animals as a provision of nature for attracting their enemies in the abysses of the ocean, or for throwing a flood of light on their own prey. I have already t shown my reasons for believing that the theory of the latter author is open to doubt, and shall make a few further remarks on the subject under the Annelida. If the notion had been promulgated that the sexes in the abysses of the ocean used their light to attract each other, and thus had a better chance of continuing the race, perhaps more might have been said in its favour.

Frequent on Fuci near the commencement of the East Rocks, and occasionally at the West Rocks. It is as common as in the south.
Class CTENOPHORE.
Two representatives only are found at St. Andrews, viz. a species of Beroid and a Pleurobrachia. 'The former occurs in vast swarms in July, indeed almost as plentifully as im the Zetlandic seas, and is easily procured by the hand-net from the rocks or at sea. The latter is equally abundant from August to the end of autumn, and even in winter, occasionally filling the towing-net or the dredge in the bay, and thrown ashore after storms on the West Sands. Few objects are more engaging than one of these spherical jellies in a clear glass vessel of sufficient size to exhibit the matchless mechanism of of its complex tentacles and the splendid iridescence of its locomotive rows.

Class ACTINOZOA.
Though the total number of species of this class at St. Andrews is small, many occur in great abundance, and espe- cially such cosmopolitan forms as Actinia mesembryanthemum, Tealia crassicornis, and Actinoloba dianthus. The frequent occurrence of Sagartia troglodytes, again, at St. Andrews, distinguishes it from the shores of the extreme south, as at Guernsey. We have not, moreover, the fine Anthea cereus of the west and south, which, for instance, in the quiet creeks of the Outer Hebrides studs the stems and blades of the tangles at the border of the littoral zone, the beautiful greenish purple tentacles gently waving with every swell of the tide ; neither is the gaudily tinted Sagartia parasitica, so character- istic of some of our southern shores, to be found between tide- marks, nor Adamsia palliata in deep water. Corynactis, the stony corals, Zoanthus, and the northern free-swimming Arachnactis albida axe entirely absent. The places of these are filled by swarms of the common forms above mentioned, and by some of the rarer types, e. g. EHdwardsia, Cerianthus, and Peachia, which seem to be characteristic of sandy beaches. A remarkable example * of the latter turned inside out occurs in my collection. It was mistaken for a curious polyp with beautifully arranged longitudinal and transverse muscular bundles, and was found inserted in a tunnel in the sand in this condition in Cobo Bay, Guernsey. It is simply a large Peachia everted.
Amongst the Aleyonarians the phosphorescent Pennatula occurs in great beauty, and replaces the Pavonarva of the west, while with Virgularva it also affords a diagnostic mark from the south. ‘The fine Gorgoniide of the latter region, again, have no representatives at St. Andrews.

Everywhere abundant under stones, and attached to rocks near low-water mark. In regard to the physiology of the digestive sac, Mr. Gosse * states that the walls of this chamber are only separated for the reception of food; but in this species the mouth often expands, and the digestive cavity dilates, so as to be readily viewed as an open and empty sac. The ciliary currents course over the lip and into the stomach; so that minute particles of nutriment might be available, though by no means necessary.

Observations, p. 656, pl. 5. f. 21 & 22): his title (A. cylin- drica) has therefore a prior claim to that of Mr. Gosse. It occurs also in the stomach of the cod.

Edwardsia Allmannt, M‘I., Proc. Roy. Soc. Ed. 1864-5.
From a shallow pool on the West Sands after a storm in October. It inhabits a distinct case, and can retract its ten- tacles and cover them by the external border of the disk. The latter is marked by eight aleyonarian divisions or radii, and has always a ragged border of the investing sheath. The disk has a pale brownish colour.
The tentacles are simple, rather blunt, pale and translucent, with a white streak in the centre; the rim of the mouth is occasionally protruded as a conical process.
This form exhibited none of the ‘‘ remarkably vigorous and spasmodic contractility ”’ ascribed by Mr. Gosse to the family ; for it was comparatively inert.

Found at the same time and place with the former. Ten- tacles 15, translucent, longer than the diameter of the oral disk, and not much tapered. A whitish ring occurs at the tip of each, and from the base a white spear-head with a transparent centre reaches more than halfway up. Oral disk streaked with white and brown. It is somewhat allied to Z.

Procured at low water from the margin of the East Rocks, and occasionally thrown on the West Sands after storms. A splendid specimen from the latter (measuring 74 inches long and as thick as a finger) in February discharged a vast num- ber of ova after a week’s confinement. The majority of these bodies were rather coarsely granular, ovoid in form; and some had minute papille at one end. No cilia were present, so that in all probability they were dead. Both examples had the first series of tentacles of the usual brown colour, with about four faintly marked whitish specks on the inner surface. The second series were uniformly brown.

XXXI.—On a true Carboniferous Nummulite. By Henry B. Brapy, F.L.S., F.G.S.
[Plate XII.]
THERE are few time-marks in the geological record that have been regarded as better established or more definite than the first appearance of the Nummulite at or near the commence- ment of the Tertiary epoch; and any indications of an earlier history which would throw back the origin of this well-known genus to a Mesozoic or Paleozoic age can hardly be without interest to the student of those genealogical problems, the bases of which are found in the revelations of paleontology.
Dr. Carpenter, in his ‘ Introduction to the Study of the Foraminifera’ (p. 276), says, “there is no fact in paleeonto- logy more striking than the sudden and enormous development of the Nummulitic type in the early part of the Tertiary pe- riod and its almost equally sudden diminution, bordering on complete extinction. The precise position of the immense beds of ‘ Nummulitic limestone,’ the vast geographical extent of which has been already sketched, has been a subject of much discussion ; but the researches of M. d’Archiac, Sir R. Mur- chison, Sir Charles Lyell, and others leave no further doubt that these beds belong to the earlier part of the Tertiary period, and that they correspond in position with the ‘ Caleaire Gros- sier’ of the Paris basin, and with the ‘ Bracklesham’ and ‘ Bagshot’ beds of the London and Hampshire basins, in which deposits alone are Nummulites found im the British Islands. Although Nummulites have been described as existing at periods anterior to this, it seems probable that such descrip- tions have been founded on the occurrence of other helicoid Foraminifera bearing an incomplete resemblance to them.”
The late Professor von Reuss, in his ‘ Entwurf einer systema- tischen Zusammenstellung der Foraminiferen’*, is scarcely less emphatic. He gives the distribution of the genus Nummulites as follows :—“ Fossil (Tertiary, especially Eocene). N. anti-
* Sitzungsb. k. k. Akad. Wissen. Wien (1861), vol. xliv. p. 391.
It is not the object of the present paper to demonstrate the continu- ance of the genus through the later Tertiary to recent times; but, lest I should be supposed to agree with the latter part of this quotation, I may just state that, as far back as 1803, Fichtel and Moll figured two recent Nummulites from the Red Sea, under the names of Nautilus radiatus and N. venosus (Test. Micr. p. 59, pl. 8); and Messrs. Parker and Jones, in their essay on Fichtel and Moll’s contributions to the Nomenclature of the Foraminifera, published a year or more before the above passage from Von Reuss, not only set this fact in a clear light, but instanced speci- mens in their collection of true recent Nummuline from Davis's Straits and from the Australian coral-reefs. I can only add that my own cabinet presents confirmatory evidence in abundance.
true Carboniferous Nummulite. 223
quior, Rouillier, from the Carboniferous limestone of Miatsch- kovo ( Orobias antiquior, dV’ Kichwald), would form a remarkable exception if its complete agreement with Nuwmmulites should be confirmed. I have not hitherto discerned any important distinction. The often-quoted living forms belong in part to Amphistegina, in part to Operculina.”
Professor Seguenza, in a table of the geological range of the various genera of fossil Foramininifera* published almost simultaneously with the two works already quoted, gives with even greater decision the Eocene as the age of the appear- ance, the Miocene as that of the extinction of the true Num- mulite.
It would be easy to add quotations of exactly similar im- port from the works of other paleontologists ; but it is scarcely worth while to cite individual authorities for what, by its ge- neral acceptance, had come to be looked upon almost in the light of a geological dogma.
Giimbel’s Researches.—Doubts as to the entire accuracy of this view have been raised from time to time, but they have not, until quite recently, been based on evidence sufficiently circumstantial to obtain much credence. ‘T'wo years ago, however, Dr. C. W. Giimbel of Munich, in the preface to his memoir on certain “ Jurassic precursors of the genera Nuwm- mulites and Orbitulites” +, reviewed the whole question of the existence of pretertiary Nummulites as it then appeared to stand. In his analysis the various published notices of Num- mulites supposed to be of earlier geological age than the be- ginning of the Tertiary epoch are recounted, the circum- stances on which they are founded criticised, and in some instances the results of a reexamination of the original speci- mens detailed. I propose to summarize the conclusions arrived at by Dr. Giimbel on this head, rather than venture upon an independent commentary, for which I should have but insufti- cient data.
Turning first to the Russian Carboniferous specimens al- ready alluded to, Dr. Giimbel accepts Prof. Reuss’s estimate of Rouillier’s Nwmmulina antiquior {—that is, that it may be a Nummulite, but that there is no sufficient evidence to prove the fact.

scription of an allied symmetrical form*, the two being placed together as representatives of a new genus ‘“ Orobias”’ (O. an- tiquior and O. equalis), is dismissed in the same way as afford- ing no evidence of value, owing to the absence of any details of microscopical structure. Indeed D’Eichwald’s separation of these two forms from the genus Nummulina is grounded on the non-tubulation of the shell and the lack of any indica- tion of a canal-system in the specimens he had examined.
Buvigniert described and figured an Upper Jurassic Num- mulite (N. Humbertina) from the Astarte-marl containing Exogyra virgula; but here, again, Dr. Giimbel regards the representation as insufficient to set its Nummuline affinity be- yond dispute, though lending probability to the assumption.
More recently Fraas}{ obtained from the Cretaceous forma- tion of Palestine certain fossils which he assigned to the genus Nummulina, describing them under three specific heads. With regard to the first of them, N. vartolaria, var. prima, Dr. Giimbel supposes that the traveller has mistaken the age of the bed from which it was derived, but does not give any very clear ground for this conclusion. The N. cre- tacea, Fraas, after careful examination of the specimens, is assigned to the genus Alveolina; and, lastly, N. arbiensis, Conrad, though certainly a Nummulina, differs so little from N. biarritzensis and N. variolaria that it is set down as pro- bably of Tertiary age.
Nummulina jurassica.—The author then proceeds to de- monstrate the existence of the Nummulite im strata of the Jurassic period, and describes, under the name N. jurassica, certain minute fossils collected by the Geological Surveyors in Franconia. The precise horizon at which the specimens were found was a sponge-bed of the Ammonites-tenuilobatus zone § anda portion of the A.-dentatus zone; the locality, Schaflohe near Amberg. The specimens are stated to be

regular, lenticular, convex bodies 5 to 7 millimetres (} to 4 inch) in diameter and 1 to 1} millim. (.4 to 3; inch) in thickness, margin obtusely rounded rather than sharp, sur- face polished and without visible perforations; some speci- mens not quite flat, but twisted. A section parallel to the surface shows six or seven rather broad convolutions, each con- sisting of numerous segments, the primordial chamber being large, and the spiral widest near the centre. The tubulation of the shell is most distinct at its thickest part.
Another Nummuline fossil of Upper Jurassic age, from Mésskirch in Baden, is partially described in the same paper. This is stated to be similar in size to the foregoing, but distinguished from it by its numerous convolutions of equal size and its much larger primordial chamber. ‘The specimens, which are in the Baden Geological Collection, appear to be too imperfect to admit of more accurate description.
Summary.—Accepting Dr. Giimbel’s facts and, in the main, his analysis of the labours of previous authors, the scattered record ot evidence as to the appearance of the Nummulite at periods anterior to the commencement of the Tertiary epoch may be summed up, in a few words, as follows :—
So far as relates to the Cretaceous system, some of the reported specimens are not Nummulites at all, and there is reason to doubt the geological origin of those which are*.
With respect to the Jurassic epoch, Buvignier probably, and Dr. Giimbel certainly, have obtained veritable members of the genus from undoubted Oolitic beds.
Lastly, although the researches of Rouillier and D’Eichwald on the fossils of the white limestones of Russia indicate a a possibility of the existence of the Nummulite in rocks of Carboniferous age, their figures and descriptions are such as no subsequent author has been able to accept as definite or entirely reliable evidence on the subject.
NUMMULINA PRISTINA, nov. sp. Introductory—At the British Association Meeting in
* Prof. Zeuschner (Verhandl. Russ.-kaiserl. min. Gesellschaft, St. Peters- burg, Jahrg. 1847, p. 105) mentions the occurrence of Nummulites in large numbers in a dolomite of Neocomian age immediately overlying Liassic beds in the Carpathian Mountains. The paper is mainly geological, and the fossils are not minutely described ; but the Nummuline character of the organisms in question is apparently sanctioned and approved by Von Keyserling ina short paper at p. 17 of the same volume. Reference to the notices of Lower Cretaceous Nummulites would be incomplete without some allusion to Zeuschner’s memoir, although the evidence it affords may not be deemed conclusive; and it may have been omitted by Dr. Giimbel on this account.
226 Mr. H. B. Brady on a
September last I described a minute fossil, Archediscus Karrert, the chief interest of which lay in two facts :—first, that whilst strikingly Nummuline in its essential features, it presented a wide divergence in some not unimportant points of structure from the typical Nummulite; and, secondly, that a fossil with such generic affinities occurred low down in the Carboniferous series at localities far apart. The description of Archediscus had scarcely appeared * when I received from my friend M. Ernest Vanden Broeck, of Brussels, a couple of packets of calcareous material, which had been forwarded with the idea that it might be of service to me in investigating the Foraminifera of the Carboniferous period.
The total number of Foraminifera which accrued from a patient search through the contents of the two packets was exceedingly small. Not more, perhaps, than three species were represented. One of them is a familiar Carboniterous form ; and another, of which only a single specimen was found, may turn out to be new. Neither of these need be noticed at present, as my object is with the third, which even cursory examination showed to be a true and most characteristic little Nummulite. Happily im the present instance no doubt need exist as to geological origin; for both locality and horizon are very accurately stated by M. Vanden Broeck; and though I hope at a future time, when I may havea larger supply of spe- cimens to work upon, to be able to elucidate further some minor details of structure, the material at hand has been sufficient to serve for the demonstration of all essential characters.
Zoological Characters and Structure.—IExternally these little fossils are convex disks ; the larger specimens are about 5 inch in diameter and ; inch thick ; the periphery is usually blunt and rounded rather than acute. ‘They are bilaterally symmetrical or nearly so, white and smooth as to surface, the uniformity being broken only by radial lines more trans- parent in texture than the rest of the shell. A section on the median plane reveals a spiral of three or four convolutions, the whorls being nearly equal in width or only increasing slightly towards the periphery, a primordial chamber relatively rather large, the ordinary chambers few in number for a Nummulite, and bounded by curved septa.
_ The characters thus broadly stated may now be examined in detail.
With respect to the exterior but little more need be said. The relation between the diameter and thickness is apparently tolerably constant—that is, about as 2} to 1; larger examples, however, exhibit some tendency to spread out and grow thinner

at the periphery. When the surface of the test is not worn, the radiation is either very indistinct or appears in the form of curved lines of somewhat darker colour, but without sensible limbation ; but in weathered specimens not only are the lines more or less elevated, but the centre from which they proceed is thickened and the test becomes to some extent umbonate also.
An accidentally split specimen (Pl. XII. fig. 4) will serve the purpose of a horizontal section. It consists of three convolu- tions, the outermost having sixteen chambers, and the second twelve or thirteen. Another, somewhat larger individual has precisely similar septation ; so that, without assigning any great importance to it, the drawing may be assumed to represent a specimen with about the normal number of chambers for the adult. condition.
The primordial chamber has been measured in three ex- amples, and the diameter found to be ‘004, -003, and -0027 of an inch, being respectively from + to +1; of the entire diameter of the test.
The minute tubulation of the shell is perfectly preserved, and may be easily seen in the transverse section under a magnifying-power of 100 diameters, as in Pl. XII. fig. 3.
The canal-system of the septa and marginal cord may be traced here and there, though only imperfectly. The trans- verse section (fig. 3) gives distinct evidence of the existence of the marginal cord; but the details of the structure are obliterated ; and in the more highly magnified drawing (fig. 5) indications are not wanting of canals traversing the septa as well as the supplementary skeleton.
Such is a detailed account, as far as can be furnished from the materials available, of the finer specimens of this Carbo- niferous Nummulite; and in the absence of larger individuals or of fragments indicating their existence, they may fairly be supposed to be adults and fully developed examples of the species. But, in addition to these, a number of smaller indi- viduals have been found apparently belonging to the same form, though neither so uniform in external appearance nor so unmistakably nummuline in character. One or two are somewhat explanate in their mode of growth, and if mature may pertain to an “Assiline” variety. Others, smaller still, not much more than a hundredth of an inch in diameter, are unsymmetrical, the convexity of the two faces being unequal and irregular. They probably represent either one of the early stages of the organi8m or perhaps an arrested condition of growth. Their precise relation to the fully developed form must be left for future determination, in the lack of sufficient specimens to work the question fully out.
228 Mr. H. B. Brady on a
A ffinities—The Nummulina antiquior of Rouillier and Vo- sinsky, judging from the figures accompanying their memoir, is esseritially unsymmetrical. Not only are the two faces very unequal in their convexity, but there seems also a tendency to irregularity 1 in the contour of the periphery. The Orobias equalis of D’Kichwald much more nearly resembles the speci- mens before us in external characters. Its separation by the author from the genus Nummulina, on the ground of the
minute structure of the shell (resting, as it apparently does, on negative data), need not be insisted upon. The absence of evidence of tubulation or canals may be dependent upon the process of mineralization; and their detection in fossils so minute, taken from a compact calcareous rock of such an age, must always be attended with difficulty. Nevertheless some doubt must rest upon this species until further specimens from the same locality, or at least from a similar horizon, have been minutely examined ; and as it differs materially in size * and septation from the organism just described, it appears undesirable to associate them under the same specific name. I propose therefore for the Belgian specimens the name Num- mulina pristina.
Referring to D’ Archiac and Haime’s monograph, the figures most closely resembling the new N. pristina_are those of N. variolaria, Sowerby, which represent a Nummulite of somewhat larger dimensions but remarkably similar in general external characters and septation. ‘Thus the nearest allies, zoologically speaking, of the Carboniferous form are the small thick members of the “ radiate”’ group regarded by Messrs. Parker and Jones as the western moditications of N. planulatat. N. variolaria especially is a poor and variable form whose descent may be easily traced.
It is not a little singular that in the Carboniferous precursor of the Nummulitic group we should have an organism so exactly corresponding in minutest features with its most modern representatives. This cannot be a mere coincidence. Is it not rather a curious exemplification of persistence of essential characters through innumerable ages, whilst modifi- cations of the original, forming collateral ‘“ species,” have, under favourable cir cumstances, exhibited an extraordinary development in size and complexity of structure and a cor- responding increase in geological importance? ‘Then, as ex- ternal conditions have become less favourable, little by little,
* The diameter, as given by D’ Eichwald, i is five times as great as the largest of the Belgian specimens.

the type has reverted to its primitive state, gradually dwindling in size, and losing by degrees those minor characters which were the easily recognized evidence of higher organization, and in its later history suggesting the lingering stages which precede complete extinction.
It has been already stated that one of the Nummulites de- scribed by Fraas from the Cretaceous beds of Palestine is named N. variolaria, var. prima, and that Dr. Giimbel’s ob- jection to its being accepted as a Cretaceous representative of the genus*appears to be grounded solely on its supposed zoological affinity. The discovery of a form so similar, in rocks of a still earlier period, appears to render such an ob- jection untenable unless otherwise supported.
Locality and Geological Position.—The locality whence the material containing the specimens above described was ob- tained is a Carboniferous-Limestone quarry near Namur— “la Carriére du Fond d’ Arquet’’—the exact geological rela- tions of which will be best understood by a brief abstract of particulars, furnished to me by M. Vanden Broeck.
The Carboniferous Limestone of Belgium is divided by M. Dupont into six sets of beds, which have been named from the localities in which they are respectively best developed. They are as follows, beginning at the lowest :—des Hcaussines, de Dinant, d Anseremme, de Vaulsor, de Namur, and de Visé. The section at the Carriere du Fond d’Arquet belongs to the top but one of these divisions, which is described as a black dolomitic limestone with large Hwomphali—black and compact at the base, and dolomitic in the upper portion, the charac- teristic fossils being Hwomphalus cequalis and E. acutus. The material collected was from three distinct bands of marly calcareous shale near the base of the section. Two out of the three contained examples of the Nummulite, though the number of specimens was exceedingly small in proportion to the quantity of material, and, owing to the nature of the matrix, almost all of them were more or less broken.
It may be well to mention that a single Nummulite of the same species has been found in a packet of greyish limestone débris from Flémalle near Liége, which, geologically, pertains to the uppermost of the divisions above quoted—that of “ Visé;” but until further specimens have been obtained from the same horizon, this second locality must be regarded as requiring confirmation.
It only remains for me to express my grateful acknowledg- ments to M. Ernest Vanden Broeck of Prussels, to whom I am indebted for the material in which this interesting little Nummulite has been found. To the pains he has taken to verify every particular as to the exact position of the beds in

To the kindly criticism of my friend and colleague Professor T. Rupert Jones, F.R.S., during the course of my work, I owe a good deal; and it is no small thing that in the results, as detailed in the foregoing pages, I have the entire concurrence of one who has contributed so much to place the classification and nomenclature of the genus Nummulina on an intelligible
basis. EXPLANATION OF PLATE XII.
Fig. 1 represents the lateral aspect, fig. 2 the periphero-lateral aspect of Nummulina pristina, magnified 50 diameters. Except a very trifling portion of the last convolution (which is broken away), this specimen is quite perfect.
Fig. 3 is a very accurate drawing of a transverse section, almost entire, magnified 100 diameters. It shows the somewhat large primor- dial chamber, the investing character of the alar lobes of the chambers of the spire, and the lamination of the test arising therefrom. The general tubulation of the shell is well seen; and at the lower end of the drawing indications of the marginal cord may be distinctly traced, though wanting in definition.
Fig. 4 is from a specimen accidentally split at the median plane, magnified 50 diameters ; one of several, more or less perfect, found in this condition. The tendency to split horizontally at the median line is of itself a Nummuline peculiarity of some significance.
Fig. 5 shows a small portion of a horizontal section, much more highly magnified (200 diameters), the object being to demonstrate the existence of a canal-system in the septa and peripheral region. More difficulty has been experienced in obtaining good horizontal sections than transverse ; this, however, has been sufficient to yield to Mr. Hollick (who has drawn direct from the object) very characteristic details of structure at one point in the peripheral convolution.
XXXII.—Notice of some new Species of Fishes from Morocco. By Dr. Aubert GUNTHER, F'.R.S., Foreign Member of the Senckenberg Society of Frankfort.
[Plates XIII. & XIV.]
A SMALL collection of marine and freshwater fishes, made by Dr. Rein and Dr. C. von Fritsch during their journey in Morocco, was placed by the former gentleman in my hands for examination. It contained four new species, which may be characterized as follows :— Serranus atricauda. Dien Aad) (la lat..115.

of the species described as being allied to Serranus cabrilla or Serranus scriba, the scales being considerably smaller than in any of those species. ‘There are eleven scales in a transverse series between the dorsal fin and the lateral line. The height of the body is two sevenths of the total length (without caudal), the length of the head one third. Snout scaleless, pointed, with the lower jaw slightly prominent, the maxillary extending beyond the vertical from the middle of the eye. ‘The diameter of the eye is two ninths of the length of the head and two thirds of that of the snout. Interorbital space flat, much less than the diameter of the eye. The serrature round the angle of the preoperculum is much coarser than on the remainder of the bone. The fourth, fifth, and sixth dorsal spines are the longest. Ventral fin terminating at a great distance from the vent ; caudal truncated. Reddish olive (in spirit), with several dark cross bands, most distinct in the middle of the side of the body ; two of them are darker and broader than the rest, and occupy the middle of the body. An oblique dark streak from the eye to the angle of the preoperculum. The soft vertical fins with numerous very small bluish ocelli. Corners of the caudal fin deep black.
I find that the specimen from Mogador is identical with others in the British Museum from the Azores, Madeira, and the Canary Islands (Teneriffe) which I have hitherto confounded with S. cabrilla.

D.11. A.8. L. lat. 32. L. transv. 5/6.
The osseous dorsal ray is strong, smooth, its stiff portion being two thirds as long as the head. There are two and a half or three series of scales between the lateral line and the root of the ventral fin. The height of the body is a little more than the length of the head, which is one fourth of the total (without caudal). Snout moderately produced, obtusely conical. Mouth inferior; lips not thickened ; barbels longer than the eye. The origin of the dorsal fm is distinctly in front of the root of the ventral, and nearly midway between the end of the snout and the root of the caudal. Caudal fin deeply forked. Coloration uniform.
This species inhabits the river Tensift. The largest of the three specimens examined is 8} inches long.

others, and not serrated. There are two and a half longitudinal series of scales between the lateral line and the root of the ventral. The height of the body is contained thrice and one fourth in the total length (without caudal), the length of the head four times. Snout short and obtuse, with the mouth inferior, broad, short, and crescent-shaped ; the lower jaw with rather a sharp margin. Barbels four, short. The diameter of the eye equals the length of the snout, and is two sevenths of that of the head. Origin of the dorsal fin nearly midway between the end of the snout and the root of the caudal, opposite to the base of the ventral. Anterior anal rays very long, ex- tending beyond the root of the caudal. A more or less distinct narrow greyish longitudinal band runs from the back part of the eye above the lateral line to the middle of the caudal fin, and separates the darker coloration of the back from the silvery of the belly.
This is a small species, apparently abundant in the streams near Morocco (Oued Ksib). The largest specimen is only 43 inches long.
Barbus nasus. Pl. XIV. fig. B. Di As. datyAa.) 1i.transyaohoe
Osseous dorsal ray strong, strongly serrated. There are five longitudinal series of scales between the lateral line and the ventral fin. The length of the head is rather more than the height of the body, and one fourth of the total (without caudal). Snout very long, much pointed, as long as the postorbital portion of the head; lips very thick, the lower with the fold interrupted in the middle ; mouth interior; barbels very fleshy and much longer than the eye, which is small. The base of the ventral fin is conspicuously in advance of the origin of the dorsal fin, which is nearly equidistant between the end of the snout and the root of the caudal. Anal fin not very narrow, none of the rays extending to the caudal. Caudal deeply forked. Coloration uniform.
The larger of the two specimens sent is 5} inches long. They bear the number 39; and on referring to the corresponding number in the list of localities I find that the specimens are said to have been obtained, with other marine fish, on the sea- shore near Mogador ; I cannot help thinking that some mistake has taken place, and that these specimens were obtained from fresh water, like the other species of this genus.
On the Geodephagous Coleoptera of New Zealand. 233
XXXITI—On the Geodephagous Coleoptera of New Zealand. By H. W. Bares, F.L.S.
Ir has been stated that the insect-fauna of New Zealand is extremely poor, and that the Coleoptera at least show great affinity with those of north temperate regions. With regard to the former statement, although some weight ought to be attached to the unanimous complaint of collectors of the general scarcity of insects, it is premature to arrive at a definite conclu- sion so long as the islands have not been thoroughly worked. At present we know scarcely any thing of the productions of the central and western portions of the Northern Island, or of the mountainous districts of the Canterbury Province in the Southern. Although insular and, especially, oceanic faunas are known to be poor, it remains to be seen whether the large area, varied surface, and lofty mountain-ranges of New Zea- land have not operated to check the process of extinction without repopulation which has impoverished other insular areas. At present the total number of species of Geodephagous Coleoptera known from the islands is 89; the British Isles have 311, and Japan 244.
The belief that the New-Zealand Coleopterous fauna is related to that of the north temperate zone is certainly ill- founded ; but it was excusable so long as describers, without attempting to study the characters of the new species before them, referred them recklessly to familiar northern genera, such as (to cite cases from the present group) Dromius, Cy- mindis, Calathus, Lebia, Harpalus, &c., the species so referred having no near affinity whatever to those genera, but belonging to purely Australian or Antarctic forms. Our material, as far as it goes, shows a great specialization of the New-Zealand fauna. ‘Thus, out of the total number of 37 New-Zealand genera of Geodephaga, no fewer than 14 are peculiar to the islands ; of the remainder, 8 are Australian and 2 are Chilian: - 7 genera only are common to New Zealand and the north tem- perate zone; and these are genera of universal distribution. There remain 6 genera, described as Argutor, Feronia, &e. which I have not yet seen, and therefore class as doubtful.
Many of the species described or enumerated in the following paper have been communicated by Messrs. Wakefield and Fereday, of Christchurch, and Mr. Lawson, of Auckland; and it 1s at the desire of these gentlemen and other local natu- ralists, who are labouring to gather together the scattered materials of the New-Zealand fauna, that I have undertaken this task.

This form is generally considered a variety of C. tuberculata. The differences, however, are considerable; for besides the width of the lateral white stripe, which reaches throughout the lateral rim of the elytra, it is a broader insect, with the elytral surface more uniform in colour and, particularly, the rows of punctures much less marked and with smaller green spots. It must rest with local entomologists to decide, by observing the forms 7” s¢tw, whether they are distinct or not.

Very similar to C. tuberculata in sculpture, colours, and markings, but certainly distinct. It is always much smaller and narrower; and although the lateral white stripe of the elytra is very similar in form and direction, the median fascia is prolonged as a curved streak some distance down the disk of the elytron. There is also a structural difference in the apex of the elytra, which may better be expressed by a tabular formula :—

Shorter in form than the common Australian D. G'ory7, and the elytra more ovate; distinguished also by the alutaceous and subopaque surface of the elytra. The head is relatively small, as in D. Goryt. The thorax is quadrate, moderately narrowed behind, with explanated and reflexed margins; the hind angles obtuse and rounded at the tip, the middle of the

and strongly sinuate near the tip, with the suture produced ;
the lateral margins are somewhat explanated and reflexed, the
strie sharply impressed, the interstices scarcely convex. Apparently abundant near Christchurch.
Dicrochile aterrima, n. sp.
D. oblonga, nigra, nitida; capite majore; thorace breviore, trans- verso, quadrato, postice paulo angustato, angulis posticis obtusis, apice rotundatis, margine vix reflexo; elytris oblongis, nitidis, fortiter punctulato-striatis, interstitiis alternis magis elevatis. Long. 5 lin.
Same size as D. subopaca, but distinguished at once by its deeper black colour and shining surface, by its larger head (owing chiefly to the much more prominent eyes), and much shorter, more transverse thorax. The palpi and tarsi are also shining black. ‘The elytra are much less sinuate truncate, and the sutural apex less produced ; the striz are punctulate, and the interstices more convex, especially the third, fifth, and seventh.

By its elytra “ paulo opacis,” this may possibly be our D. subopaca; but the description of the thorax cannot possibly be intended for that species (‘ capite fere duplo latiore, ovali”’). There is not the faintest approach to the oval form in the thorax of D. subopaca.
Obs. Dicrochile Fabret and D. anchomenoides, cited by au- thors as described by Guérin (Ann. Soc. Ent. Fr. 1846, Bull. p. 103), must be erased from the list of this genus, as the species’ are merely named in the place quoted, not

Blanchard’s description is so vague that it is difficult to de- termine to which of the New-Zealand species of the same size (12 to 14 millims.) it applies. Judging from the figure and the expressions ‘ater, obscurus” and “ Elytres obscures, planes,” I refer to it a slender, subopaque species existing in some of the London collections, and remarkable for the very sharp furrows and ridges of all the tarsi, and for the uneven slightly rugose thorax, which is subcordate in form, but with produced and rather acute hind angles. The head and eyes are very similar in form to those of P. scrobiculatus of Europe. White’s description of A. deplanatus agrees pretty well with the same insect ; and [ have little hesitation in adopting the name, although I have not seen his type.

The type in the British Museum is a slender insect, with very elongate thorax, sinuate-angustate behind, and with pro- duced hind angles; the antenne, palpi, and legs testaceous yellow.

Colensonis, has a deep central groove, and on each side a curved, shallow, impressed line
proceeding from the basal fovea and nearly reaching the ante- .

The eyes are much more prominent than in A. micans, and the palpi shorter and more robust. The frontal foveole are deep and well defined. The elytra are very obliquely and rather strongly sinuate at the apex, with the suture strongly produced ; the strize are sharp and fine, equally impressed from base to apex, and finely punctu- late or crenulated ; the interstices quite plane, with three large punctures on the third; the deflexed margins and extreme edge of the lateral rims rufo-piceous. The antenne are robust from the fourth joint, black, with rufous bases to the joints. The palpi and femora shining black ; the trochanters reddish testaceous ; the tibiz: and tarsi pitchy red.

According to the type in the British Museum, this is a species closely allied to the common Australian A. marginellus (Erichson) ; it differs in being less shining, and in the much shorter thorax, the sides of which narrow much more abruptly to the front angles. It is common and generally distributed in New Zealand; and [I have compared a long series with an equal number of the Australian species.
The species has none of the distinguishing characters of Colpodes ; the fourth joint of the tarsi, however, is rather more distinctly triangular and emarginate than is usual in Anchomenus. It is closely allied to our A. Lereday?, but is much larger, more brassy, and with clearer yellow margins to the thorax and elytra, besides having yellow legs.
Tropopterus sulcicollis, n. sp.
T. ellipticus, niger, nitidus ; antennis, palpis et pedibus piceo-rufis ; capite spatio inter sulcos laterales haud carinato; thorace quadrato, vix transverso, medio rotundato, antice plus quam postice angustato, angulis posticis productis rectis, basi utrinque fovea sulciformi; elytris convexis, striato-punctatis. Long. 34 laa?)
Resembles the genus Odpterus, but distinguished by the pubescence of the antenne not beginning before the fourth Joint, and by thé labial palpi having their terminal joint obtuse-ovate, instead of acuminate, Aeyees in all essential points with the Chilian genus Z’ropopterus ; allied to Colpodes, in which the forehead has on each side two grooves with a carinate interval between them. The eighth and ninth striz of the elytra are sunk in a broad groove near the apex ; and the seventh at that part is bordered by a sharp carina. The sixth and seventh striz are nearly obsolete.

almost asin Oépterus. The posterior narrowing of the thorax
is strongly sinuated and the hind angles produced ; the whole base is very coarsely punctured; the dorsal line and long basal fovez are deeply impressed. The sutural rows of punc- tures are impressed in striz, the rest are superficial ; the form of the lateral striz is as in 7’, sulcicollis.

_ This fine insect was sent home in some numbers, from Christchurch, by Mr. Fereday. The colour is not always cupreous, but some specimens are black, with the green margins occasionally scarcely perceptible. It may always be distinguished from the obscure-coloured 7. rectangulus by its larger and broader shape, more protuberant cheeks behind the eyes, and by the thorax being more dilated in front.

shorter and the thorax rather longer than in that species. The thorax is very nearly as long as broad, and is somewhat re- gularly and slightly rounded on the sides, the greatest width being in the middle ; behind it is very much less sinuate, and the hind angles are less produced than in subenea; the basal fovea also is larger, and offers on its outer slope a distinct second smaller fovea; but some trace of this is visible in well-deve- loped examples of subenea. The hind legs are remarkably short, and the femora are widely dilated beneath, forming a tooth, between which and the base is lodged the elongated tro- chanter.

Holcaspis ovatella, Chaud. Bull. Mosc. 1865, ii. p. 103.
Distinguished by its three punctures on the third interstice of the elytra; otherwise similar to HH. elongella.
The precise locality of this distinct species (9 lines long) is not known. Ihave one example obtained from a New-Zealand collection, probably from the Southern Island.
The genus Holcaspis resembles in general form the parallel species of Pterostichus, having, like them, very short metatho- racic episterna and the marginal stria of the elytra duplicated towards the apex. It is distinguished by the base of the scutellum being scored by a number of short fine lines; this character, however, is seen in some European species of the Feronia group—e. g. Haptoderus abaxoides, De}., Tapinopterus cephalotes, Gaut., and others.

Haptodert. The palpi have the terminal joints narrowed to the tip and very briefly (the maxillaries in the male not at all) truncated. The head is rather small, and shows scarcely any trace of the usual frontal foveze; the thorax has on each side of the base a single deep, almost sulciform, fovea, and its whole surface isimpunctate. The elytra have a well-developed scutellar striole between the suture and the first stria; the in- terstices are plane in the subopaque female and a little more convex in the shining male, but in both sexes they become narrow and convex at the apex, and the first stria is continued round the apex to the marginal stria.
Argutor erythropus, Blanch., as far as the very insuffi- cient description goes, agrees with this species ; but no mention is made of the two punctures on the third interstice.

8-9 millims. Rather broad, black; elytra nearly plane ; palpi clear red; thorax with two lineiform foveze on each side.
The description almost applies to the O. (Holcaspis) sylvaticus of the same author; and the species probably belongs to [{ol- caspis.

The Naturalist in Nicaragua. By THomas Betz, F.G.S. London: Murray.
Tuts is another addition to that pleasant class of books of travel the type of which is Darwin’s ‘ Journal of a Naturalist,’ and which have acquired increased interest since the appearance of the ‘Origin of Species.’ Mr. Belt’s special line of study appears to be mining geology, his mission in Nicaragua being the management of the gold-mines of Chontales, situated about midway between the Atlantic and Pacific sea-boards ; but his observations range over other de- partments of geology and physical geography, and a taste for natural history, especially its philosophical side, led him to devote much of his leisure time to collecting and observing the plants and animals of the districts he visited. The result is a volume full of original observation and vigorous reasoning. Some of the reasoning, in fact, is likely to be considered too bold ; but it displays the working of an original mind, well stored with accurate knowledge, and endeavouring to explain some of the knottiest problems in physical science. Asa, narrative of travel the book is agreeable reading, without, perhaps, having that fascination which other works of the same class, con- taining more exciting personal experience and dealing with regions of more intrinsic interest, are found to possess. There are not
Bibliographical Notice. 247
wanting, however, descriptive passages of considerable power and truthfulness ; and many of the general observations and reflections scattered throughout the work are instructive and sound.
The mode in which Mr. Belt handles the subject of the glacial epoch, and the influence it had upon the distribution of plants and animals, may be selected as an illustration of the above remarks. In the course of a journey he took to the mountainous district near Ocotal, on the northern frontier of Nicaragua, he discovered an ex- tensive deposit of unstratified gravel with boulders, which, he had no doubt, formed the moraine of a huge glacier, at an altitude of not more than 2000 to 3000 feet above the present sea-level. The deposit had been worn through by streams, in some places to the depth of 200 feet, exposing numerous vertical sections; and, with the single exception of striated surfaces, he observed all the same signs of glacial action which he had studied in Wales, Scotland, and Nova Scotia. Reasoning from this and other evidence which he adduces, he first states the grounds on which he thinks it must be concluded that the phenomena were due to glacier ice and not to icebergs; and he then draws the inference that the whole of the high land between the tropics must have been, during the glacial epoch, covered with snow and ice. A similar conclusion, as is well known, had been arrived at before by other writers; but no one had hitherto offered a satisfactory explanation of the non-extinction, in that state of things, of the vast host of peculiar forms of plants and animals still existing in the equatorial lowlands. Mr. Belt, in accounting for this, adopts and extends an hypothesis of Mr. Alfred Tylor, to the effect that the quantity of water locked up in the polar ice-cap lowered the level of the sea to the extent of 600 feet. He believes the depression would exceed 1000 feet, and that the tracts of sea-bottom thereby laid bare would form a refuge for the equatorial fauna and flora. The hypothesis is not fully worked out; and it would be necessary, before it can be seriously dealt with, to explain the climatal conditions of the lowlands between the tropics at a time when all the elevated land was subject to arctic rigour. One obyious consideration he has certainly omitted to note, viz. that a lowering of the sea by 1000 feet would act on climate chiefly by making all the land virtually 1000 feet higher, as the atmosphere, being constant in total amount, would descend with the lowering of the sea-level. This would produce a train of conse- quences in a high degree favourable to the state of things Mr. Belt supposes to have existed.
With regard to its other effects on the distribution of plants and animals, he ingeniously points out how the laying bare of shallow seas, such as those separating Borneo and the neighbouring islands from continental Asia, would account for the present existence of so many species and genera of terrestrial animals in lands now separated from each other. He goes, however, too far in reviving the fabled Atlantis. Whatever we may think of this hypothesis in the form too briefly sketched out by Mr. Belt, there can be no doubt of its great suggestiveness, and of the justness of his view in requiring
248 Bibliographical Notice.
that any such theory shall fit the known facts of biology as well as those of geology and physics.
Some of the most interesting of Mr. Belt’s zoological observations relate to ants, of whose habits he was evidently a close observer. Thus with regard to the @codome, or leaf-cutting ants, he is the first to record any thing of the internal economy of their vast sub- terranean dwellings. He had to do battle with these fearful depre- dators in his attempts to cultivate various useful and ornamental plants in his garden, and gives an amusing description of his en- deavours to extirpate them by pouring buckets-full of diluted car- bolic acid down the broad passages which lead to their cavernous abodes. But the most extraordinary thing he relates of them is that their habitual food is a fungus, which they sedulously grow in their underground chambers. In fact, it is for this purpose, he found, that they require the vast quantity of pieces of leaves which the workers spend nearly all their lives in cutting from young trees and carrying to their abodes—the leaves not being used as food, nor as a thatch for their nests, as had been surmised by other writers, but being stored in chambers, where, in decaying, they produce a mi- nute fungus, on which the larve and small workers seem to feed. He gives also many interesting details regarding the various species of Eciton, or foraging ant, which hunt through the Tropical- American forests in large armies, and states a fact which is entirely new, viz. that they construct no formicarium, but have only temporary abodes. The facts cited in illustration of the reasoning-powers of ants are numerous throughout the volume ; it is a subject on which he tried many experiments with curious results. ‘The best case he gives is that of a marauding procession of Gicodome tunnelling under the rails of a tramway to avoid being crushed by the passing waggons. One day when the waggons were not running, Mr. Belt stopped up their tunnel with stones; but although great numbers were thus cut off from their nest, they would not cross the rails, but set to work making fresh tunnels underneath them. It is impossible to do more than allude to the vast store of suggestive facts and reasoning on this subject contained in the volume.
The relations of insects to flowers in regard to cross-fertilization form the subject of many original observations, recorded and argued out to definite conclusions with great keenness and circumspection. The same may be said with reference to another less-worked phase of insect- and plant-relationship, viz. the special adaptations of leaves to attract pugnacious ants as defenders of the plants against defoli- ation by leaf-cutting ants, caterpillars, and other phytophagous ani- mals. This subject is dealt with in a series of observations on the bull’s-horn-thorn Acacia, on species of Melastoma haying glandular swellings at the bases of their leaves containing a sweet fluid to attract ants, and on the Cecropia trees, which invite protecting ants to dwell in their hollow chambered stems. The ants thus attracted form, as Mr. Belt expresses it, a most efficient standing army for the
lant. ; Mimetic resemblances come in for a large share of Mr. Belt’s

attention. He had commenced his observations in Nicaragua with the advantage of some previous knowledge of the subject, and was therefore prepared to direct his inquiries to many points that required elucidation before the Darwinian explanation of these phenomena can be said to be established. Thus we find recorded his experiments on living insects which are the objects of mimicry by other forms, as to their distastefulness as food to insectivorous animals. Whenever he observes an instance of mimetic resemblance, he reasons out its causes and conditions instead of merely stating it. One of the most striking cases he mentions is that of a green leaf-like locust, which almost alone of all other living things stood its ground amid a destroying host of foraging ants. It stood immovable whilst the ants ran over its legs, and allowed him to pick it up and replace it amongst the ants without making an effort to escape. It might easily have flown away; but it would then only have fallen into as great a danger ; for the numerous birds that accompany the army-ants are ever on the outlook for any insect that may fly up. Another case is that of a Longicorn beetle, belonging to a genus the species of which re- semble various other objects: those members of the genus which live on dead wood are coloured so as to resemble lichen-stained bark ; but one species (Desmiphora fasciculata) resembles a brown hairy caterpillar; and this he found only on leaves.
Mr. Belt’s numerous observations on birds, as well as those on the few mammals he met with, are marked by the same originality and suggestiveness. His charming descriptions of the habits and haunts of humming-birds will attract many readers besides ornithologists. The use of the expanded white tail of the Florisuga mellivora in courtship (p. 112), which he fortunately had opportunities of ob- serving, will be a welcome fact to the partisans of the Sexual Selee- tion hypothesis. The volume, besides, contains abundant contribu- tions to the general physical geography of the country (his remarks on the retrocession of the frontier of the virgin forest being especi- ally worthy of attention) and to the ethnology of Nicaragua and neighbouring countries.

“On the Structure and Development of the Skull in the Pig (Sus scrofa).” By W. K. Parker, F.RS.
I haye for some years past determined to concentrate my atten- tion on some one type of Mammalian Skull, so as to be able to present to the Royal Society a paper similar to those which have
250 Royal Society :—
already appeared on other Vertebrate Skulls. I was led to work out this MEDIUM TYPE, and not a more generalized form, such as the Guinea-pig (see “‘On the Development of the Frog’s Skull,” Phil. Trans. 1871, p. 203), through the circumstance of an offer from nry friend Mr. Charles Stewart to put some seventy embryos of the Common Pig into my possession. In the present communication 1 have had the invaluable help of advice and oversight from Pro- fessor Huxley; whilst the labour of my hands has been lightened by my son, Mr. T. J. Parker, who prepared for me all the more delicate sections. The embryos ranged in size from two thirds, or less, of an inch in length, with the head only equal in size to a sweet pea, whilst the head of the largest specimen was the size of that of the Common Squirrel. To these I have added young pigs at birth, and have taken as the last stage the skull of a half- grown individual.
The most important results of the present investigation may be stated as follows :—
1. In a pig-embryo, in which the length of the body did not exceed two thirds of an inch, and four postoral clefts were present, the cranio-facial skeleton was found to consist of :—(a) the noto- chord, terminating by a rounded end immediately behind the pitui- tary body.
(5) On each side of the notochord, but below it, there is a cartila- ginous plate, which in front ends by a rounded extremity on a level with the apex of the notochord, while behind it widens out and ends at the free lower margin of the occipital foramen. These two plates, taken together, constitute the “investing mass” of Rathke. In this stage they send up no prolongations around the occipital foramen; in other words, the rudiment of the basioc- cipital exists, but not of the exoccipital or superoccipital.
(c) The large oval auditory capsules lie on each side of the anterior half of the investing mass, with which they are but imper- fectly united: there is no indication of the stapes at this stage.
(d) The trabecular or first pair of preoral visceral arches in- close a lyre-shaped pituitary space; they are closely applied to- gether in front of this space, and, coalescing, give rise to an azygous preenasal rostrum. ‘They are distinct from one another and the investing mass.
(e) The pterygo-palatine or second pair of visceral arches lie in the maxillo-palatine processes, and are therefore subocular in position. Hach is a sigmoid bar of nascent cartilage, the incurved anterior end of which lies behind the internal nasal aperture, while the posterior extremity is curved outwards about the level of the angle of the mouth. The pterygo-palatine cartilages are perfectly free and distinct from the first preeoral and from the first postoral arch.
(f) The mandibular or first pair of postoral visceral arches are stout continuous rods of cartilage which lie in the first visceral arch behind the mouth. The ventral or distal ends of these arches are not yet in contact; the dorsal or proximal end of each is somewhat pointed and sharply incurved, pushing inwards the
Mr. W. K. Parker on the Skull of the Pig. 251
membrane which closes the first visceral cleft and is the rudiment of the membrana tympani.
(g) The hyoid or second pair of postoral arches are in this stage extremely similar to the first pair, with which they are parallel. They are stout sigmoid rods of cartilage, which are sepa- rated at their distal ends, present an incurved process at their opposite extremities, and are not segmented.
(h) The thyro-hyal or third postoral arches, which correspond with the first branchial of the branchiate vertebrata, are repre- sented by two short cartilaginous rods which lie on each side of the larynx.
(i) The olfactory sacs are surrounded by a cartilaginous capsule, which has coalesced below with the trabecula of its side; while, within, the mucous membrane lining the capsule presents eleva- tions which indicate the position of the future turbinal outgrowth of the capsule.
In this stage the posterior nares are situated at the anterior part of the oral cavity, as in the Amphibia, and the roof of the mouth is formed by the floor of the skull, the palatal plate of the maxille and palatine bones being foreshadowed by mere folds. The outer end of the cleft between the first and second preoral arches is the rudiment of the lachrymal duct, while its inner end is the hinder nasal aperture. The gape of the mouth is the cleft be- tween the second proral and first postoral arch. The auditory passage, representing the Eustachian tube, tympanum, and ex- ternal auditory meatus, is the cleft between the first and second postoral arches. The proximal end of the mandibular arch, there- fore, lies in the front wall, and the hyoid in the hinder wall of the auditory passage.
2. In an embryo pig, an inch in length, (a) the notochord is still visible ; (4) the investing mass, the halves of which are com- pletely confluent, has become thoroughly chondrified, and is con- tinued upwards at each side of the occipital foramen to form an arch over it.
*(c) The auditory capsules are still distinct from the investing mass, and a plug on the outer cartilaginous wall of each has be- come marked off as the stapes.
(d) The hinder ends of the trabecular arches have coalesced in front of the pituitary body, but they are not yet confluent with the investing mass.
(e) The pterygo-palatine rods have increased in size ; they have not become hyaline cartilage, but are beginning to ossify in their centre.
(f) In the mandibular arch the proximal end has become some- what bulbous, and is recognizable as the head of the malleus, whilst the incurved process, still more prominent than before, is the manubrium mallet. The rest of the arch is Meckel’s cartilage ; outside this a mass of tissue appears, which is converted into car- tilage, rapidly ossifies, and eventually becomes the ramus of the mandible.
252 Royal Society :—
(g) The proximal end of the hyoidean arch, similarly enlarging and articulating with the corresponding part of the mandibular arch, becomes the incus, the incurved process attaching itself to the outer surface of the stapes and becoming the long process of the incus. The incus, thus formed out of the proximal end of the hyoidean arch, becomes separated from the rest of the arch by con- version of part of the arch into fibrous tissue, and by the moving downwards and backwards of the proper hyoid portion of the arch. A nodule of cartilage left in the fibrous connecting band becomes a styliform interhyal cartilage, while the proximal end of the detached arch becomes the stylo-hyal.
(h) The thyro-hyals have merely increased in size and density ; they closely embrace the larynx by their upper ends.
(¢) The olfactory capsules are well chondrified ; their descending inner edges have coalesced with each other and, below, with the trabecule to form the great median septum: the turbinal out- growths are apparent.
In this stage, the alisphenoids and orbito-sphenoids appear as chondrifications of the walls of the skull, quite separate from the investing mass and from the trabecule.
The floor of the pituitary space chondrifies independently of the trabecule and investing mass, but serves to unite these four cartila- ginous tracts.
3. In an embryo pig, 14 inch in length, (a, 6, ¢) the primordial cranium is completely constituted as a cartilaginous whole, formed by the coalescence of the investing mass and its exoccipital and superoccipital prolongations, the modified trabeculae, the subpitui- tary cartilage, the auditory capsules, and alisphenoidal and orbito- sphenoidal cartilages, and the olfactory capsules. The notochord is yet to be seen extending in the middle line from the hinder wall of the pituitary fossa (now the “ dorsum selle”) to the posterior edge of the occipital region.
(d) The trabecular arches form the sides of the sella turcica, the presphenoid, and the base of the septum between the olfactory capsules ; in front, where they form the azygous “ preenasal,” they are developed backwards as “ recurrent bands,” elongations of their free recurved “ cornua.”
(e) The pterygo-palatine arches, still increasing in size, but not chondrifying, are rapidly ossifying; they are half-coiled lamin bounding the posterior nasal passages.
(f) The mandibular arch and the rudimental ramus have become solid cartilage, and the latter is ossifying as the dentary; the distal part of each mandibular rod unites with its fellow for some distance.
(g) The hyoid arches are each fully segmented as incus, with its *‘ orbicular” head, interhyal, stylo-hyal, and cerato-hyal.
(h) The thyro-hyals are merely larger and denser.
(7) The olfactory capsules have the turbinal outgrowths all marked out as alinasal, nasal, and upper, middle, and lower tur- binals. -
Mr. W. K. Parker on the Skull of the Pig. 253
4. In pigs of larger size the form and proportions of the parts of the cranium become greatly altered, and ossification takes place on an extensive scale, but no new structure is added.
5. It follows from these facts that the mammalian skull, in an early embryonic condition, is strictly comparable with that of an Osseous Fish, a Frog, or a Bird at a like period of development, consisting as it does of
(a) A cartilaginous basicranial plate embracing the notochord, and, like it, stopping behind the pituitary body.
(6) Paired cartilaginous arches, of which two are preoral, while the rest are postoral.
(c) A pair of cartilaginous auditory capsules.
(¢) A pair of cartilaginous nasal capusles.
Further, that in the Mammal, as in the other Vertebrata the deve- lopment of the skull of which has been examined, the basicranial plate grows up as an arch over the occipital region of the skull, and coalesces with the auditory capsules, laterally, to give rise to the primordial skeleton of the occipital, periotic, and basisphenoidal regions of the skull. The trabecule become fused together, and, uniting with the olfactory capsules, give rise to the presphenoidal and ethmoidal parts of the cranium; and the moieties of the skull thus resulting from the metamorphosis of totally different morphological elements become united and give rise to the pri- mordial cranium.
As in the Salmon and Fowl, the second pair of preoral arches give rise to the pterygo-palatine apparatus; in the Frog this arch is late in appearance, and is never distinct from the trabecular and mandibular bars, serving as a conjugational band between them. The mandibular arch, which in the Salmon becomes converted into Meckel’s cartilage, the os articulare, the os quadratum, and the os metapterygoideum, in the Frog into Meckel’s cartilage and the quadrate cartilage (which early becomes confluent with the periotic capsule), in the Bird into Meckel’s cartilage, the os articulare, and the os quadratum (which articulates movably with the periotic cap- sule), in the Pig is metamorphosed into Meckel’s cartilage and the malleus, which is loosely connected with the tegmen tympani, an outgrowth of the periotic capsule.
Meckel’s cartilage persists in the Fish and in the Amphibia, but disappears early in the Bird, and still earlierin the Mammal. The permanent ossifications of the mandible are all membrane-bones in Fish, Frog, and Fowl, but in the Mammal (exceptionally) the ramus has a cartilaginous foundation. The hyoidean becomes closely united with the mandibular arch, and then segmented, in the Fish, into the hyo-mandibular, the stylo-hyal, cerato-hyal, and. hypohyal—the hyo-mandibular, or proximal segment, articulating with the outer wall of the periotic, and many of the segments of the arch becoming dislocated.
In the Frog, the hyoid also becomes segmented, but only after extensive coalescence with the mandibular arch. The proximal segment becomes the suprastapedial (hyo-mandibular) with its ex-

trastapedial process, and, extending inwards as mediostapedial and interstapedial, articulates with the stapes, developed by segmen- tation from the outer wall of the auditory capsule. The stylo-hyal is dislocated and becomes connected with the auditory capsule below the stapes (opisthotie region).
In the Bird, the hyoidean arch remains distinct from the man- dibular. Whilst in its primordial condition it coalesces by its incurved apex with the auditory capsule in front of the promon- tory, before the stapedial plug is segmented. It then chondrifies as three distinct cartilages—an incudal, a stylo-hyal, and, distally, a cerato-hyal. The stapes becomes free from the auditory capsule, but remains united with the cartilaginous part of the incus (medio- stapedial); the ascending part is largely fibrous (suprastapedial), and the part loosely attached to the mandibular arch is the elon- gated extrastapedial. The short stylo-hyal afterwards coalesces with the body of the upper or incudal segment by an after- growth of cartilage (the interhyal tract) ; a long membranous space intervenes between it and the glossal piece (cerato-hyal.) Thus the “columella” of the Bird is formed of one periotic and three hyoidean segments.
In the Pig, the hyoidean arch is distinct, but articulates closely with the mandibular; its upper segment (hyo-mandibular) is con- verted into the incus, and becomes connected with the stapes. The stylo-hyal is dislocated and coalesces with the opisthotic region of the auditory capsule.

“On the Nervous System of Actinia.”—Part I. By Professor P. Martin Duncan, M.B. Lond., F.R.S., &e.
After noticing the investigations of previous anatomists in the histology of the chromatophores, the work of Schneider and Rotteken on these supposed organs of special sense is examined and criticised.
Agreeing with Rotteken in his description, some further in- formation is given respecting the nature of the bacillary layer and the minute anatomy of the elongated cells called “cones” by that author. ‘The position and nature of the pigment-cells is pointed out, and also the peculiarities of the tissues they environ. It is shown that the large refractile cells, which, according to Rét- teken, are situated between the bacilli and the cones, are not ‘invariably in that position, but that bacilli, cones, and cells are often found separate. They are parts of the ectothelium, and when conjoined enable light to affect the nervous system more readily than when they are separate. Further information is given respecting the fusiform nerve-cells and small fibres noticed by Rotteken in the tissue beneath the cones ; and the discovery of united ganglion-like cells and a diffused plexiform arrangement
Miscellaneous. 255
of nerve is asserted. The probability of a continuous plexus round the Actinia and beneath each chromatophore is suggested, and the physiological action of the structures in relation to light is explained.
The minute structure of the muscular fibres and their attached fibrous tissue in the base of Actinia is noticed; and the nervous system in that region is asserted to consist of a plexus beneath the endothelium, in which are fusiform cells and fibres like sym- pathetic nerve-fibrils. Moreover, between the muscular layers there is a continuation of this plexus, whose ultimate fibrils pass obliquely over the muscular fibres, and either dip between or are lost on them.
The other parts of the Actinia are under the examination of the author, but their details are not sufficiently advanced for publication. The nervous system, so far as it is examined, consists of isolated fusiform cells with small ends (Rétteken), and of fusiform and spherical cells which communicate with each other and with a diffused plexus. The plexus at the base is areolar; and its ultimate fibres are swollen here and there, the
whole being of a pale grey colour.

Occurrence of Gigantic Cuttlefishes on the Coast of Newfoundland. By A. E. VreRRILt.
ConsIDERABLE popular interest has been excited by several articles that have recently been published and extensively circulated in the newspapers of Canada and the United States, in regard to the ap- pearance of gigantic “ squids ” on the Newfoundland coast. Having been so fortunate as to obtain, through the kindness of Professor 8. F. Baird, the jaws and other parts of two of these creatures, and, through the courtesy of Dr. J. W. Dawson, photographs of portions of two other specimens, I have thought it worth while to bring together, at this time, the main facts respecting the several speci- mens that have been seen or captured recently, so far as I have been able to collate them, reserving for a future article the full de- scriptions and figures of the jaws and other portions now in my possession.
We now have reliable information concerning five different ex- amples of these monsters that have appeared within a short period at Newfoundland.
1. A specimen found floating at the surface, at the Grand Banks, in October 1871, by Captain Campbell, of the schooner ‘ B. D. Haskins,’ of Gloucester, Mass. It was taken on board, and part of it used for bait. Dr. A. 8. Packard has given, in the ‘ American Naturalist,’

vol. vii. p. 91, Feb. 1873, all the facts that have been published in regard to this individual. But its jaws have since been sent to the Smithsonian Institution, and are now in my hands to be described and figured. They were thought by Professor Steenstrup, who saw a photograph of them, to belong to his Architeuthis monachus, which inhabits the northern coasts of Europe, but is still very imperfectly known. The horny jaw or beak from this specimen is thick and strong, nearly black; it is acute at the apex, with a decided notch or angle on the inside, about ‘75 of an inch from the point; and beyond the notch is a large prominent angular lobe. The body of the specimen from which this jaw was taken is stated to have measured 15 feet in length and 4 feet 8 inches in circumference. The arms were mutilated ; but the portions remaining were estimated to be 9 or 10 feet long, and 22 inches in circumference, two being shorter than the rest. It was estimated to weigh 2000 pounds.
2. A large individual attacked two men, who were in a small boat, in Conception Bay ; and two of the arms which it threw across the boat were cut off with a hatchet and brought ashore. Full ac- counts of this adventure, written by Mr. M. Harvey, have been published in many of the newspapers*. One of the severed arms, or a part of it, was preserved in the museum at St. John’s; and a pho- tograph of it isnow before me. ‘This fragment represents the distal half of one of the long tentacular arms, with its expanded terminal portion covered with suckers, 24 of which are larger, in two rows, with the border not serrate, but 1-25 inch in diameter; the others are smaller, very numerous, with the edge supported by a serrated calcareous ring. The part of the arm preserved measured 19 feet in length, and 3°5 inches in circumference, but wider, “like an oar,” and 6 inches in circumference, near the end where the suckers are situated ; but its length, when entire, was estimated at 42 feet. The other arm was destroyed, and no description was made; but it was said to have been 6 feet long and 10 inches in diameter ; it was evidently one of the eight shorter sessile arms. The estimate given for the length of the ‘‘ body” of this creature (60 feet) was probably intended for the entire length, including the arms.
3. A specimen was found alive in shallow water, at Coomb’s Cove, and captured. Concerning this one I have seen only news- paper accounts. It isstated that its body measured 10 feet in length and was ‘nearly as large round as a hogshead” (10 to 12 feet) ; its two long arms (of which only one remained) were 42 feet in length and “as large as a man’s wrist ;” its short arms were 6 feet in length, but about 9 inches in diameter, “ very stout and strong ;” the suckers had a serrated edge. The colour was reddish. The loss of one long arm and the correspondence of the other in size to the one amputated from No. 2, justifies a suspicion that this was actually

the same individual that attacked the boat. But if not, it was pro- bably one of the same species and of about the same size.
4, A pair of jaws and two of the suckers were recently forwarded to me from the Smithsonian Institution. These were received from Rey. A. Munn, who writes that they were taken from a specimen that came ashore at Bonavista Bay, that it measured 32 feet in length (probably the entire length, including more or less of the arms), and about 6 feet in circumference. This jaw is large and broad, but much thinner than that of No. 1, and without the deep notch and angular lobe seen in that specimen. It probably belongs to the Architeuthis dux of Steenstrup, or at least to the same species as the jaw figured by Dr. Packard.
5. A smaller specimen, captured in December, in Logic Bay, about 3 miles from St. John’s, in herring-nets. Of this I have a description in a letter to Dr. Dawson from the Rev. M. Harvey, who has also ’ published a brief account of it in the ‘ Morning Chronicle’ of St. John’s. The letter is accompanied by two photographs of the specimen—one showing the entire body, somewhat mutilated ante- riorly, the other showing the head with the ten arms attached. The body of this specimen was over 7 feet long, and between 5 and 6 feet in circumference; the caudal fin was 22 inches broad, but short, thick, and emarginate posteriorly on each side, the end of the body being acute; the two long tentacular arms were 24 feet in length, and 25 inches in circumference, except at the broader part near the end, the tips slender and acute; the largest suckers 1-25 inch in diameter, with serrated edges; the eight short arms were each 6 feet long; the two largest were 10 inches in circumference at base, the others were 9,8, and 7 inches. These short arms taper to slender acute tips; and each bears about 100 large, bell- shaped suckers with serrated margins. Each of the long arms bears about 160 suckers on the broad terminal portion, all of which are denticulated ; the largest ones, which form two regular alter- nating rows of twelve each, are about an inch in diameter. There is also an outer row of much smaller suckers, alternating with the large ones, on each margin; the terminal part of these arms is thickly covered with small suckers; and numerous similar small suckers are crowded on that portion of the arms where the enlarge- ment begins, before the commencement of the rows of large suckers. The arrangement of the suckers is nearly the same as on the long arm of No. 2; but in the latter the terminal portion of the arm, be- yond the large suckers, as shown in the photographs, is not so long, tapering, and acute; but this may be due to the different conditions of the two specimens. It is probable that this was a young speci- men of the same species as No. 2.
From the facts known at present, it appears probable that all these specimens, and several others that have been reported at va- rious times from the same region, are referable to}two species—one (probably Architeuthis monachus) represented only by the first of those enumerated above, and having a more elongated form of body and stouter jaws; the second (probably A. dux) represented by
258 Miscellaneous.
Nos. 2 to 5, above described, having a short, thick, massive body, and broad, but comparatively thin jaws, which are also different in form. Some of the differences in size and proportions, and in the suckers, observed among the four specimens referred to the latter species may be due to sex ; for the sexes differ considerably in these characters in all known cuttlefishes.— American Journal of Science and Arts, Feb. 1874.
Umbellula from Greenland. By Josuva Linpant.
Mr. Lindahl has written a paper on the two specimens of Umbel- lula taken on the coast of Greenland. It will appear in the next volume of the ‘ Kongl. Vetenskaps-Akad. Handlingar’ of Stockholm, illustrated with three quarto plates, each containing several figures.
Mr. Lindahl considers the two specimens different from one another and from the Umbellula encrinus of Linneeus figured by Mylius and Ellis. He observes he must confess that the difference may depend upon the difference of age, and as for U. encrinus upon imperfection in the figure and description. At all events, he thinks it better to describe his two specimens as two different and new species in order to call attention to the differences, observing “ that when new investigations of the deep sea have brought together richer materials, as no doubt they will, if I have committed a mistake in this respect it will be easily corrected.” He considers that Umbel- luda and Crinillum form one group, as Dr. Gray has pointed out. He regards them as true Pennatulids, and puts them among the “Zunft” Pennatulide as the fifth family, Umbellule, close to the family Bathyptilee (Kolliker, ‘Die Pennatuliden,’ p. 380). The rachis, or pars polypifera, is about one fortieth of the length of the stem ; polypes not retractile, without calycles, the lateral ones large and the dorsal small; the zooids are crowded in lateral and ventral shields (“‘ Wilste,” Koll.) ; the axis square, with one deep groove on each side; uo spicula in any part of body.
On the Bos pumilus of Sir Victor Brooke. By Dr. J. E. Gray, F.R.S. &e.
Sir Victor Brooke’s paper in the last number of the ‘Annals’ shows that he does not understand the question between us, and it contains
many erroneous statements. I will therefore state the question as -
shortly as I can.
Sir Victor Brooke states at p. 159 :—‘ Turton, having founded the name Bos pumilus upon Pennant’s ‘ Dwarf,’ it follows that the horns spoken of and figured by Pennant are typical specimens of ‘Bos pumilus.’”” The statement that the fragment of the forehead and horns are typical of Pennant’s “ Dwarf,” and therefore of the B. pumilus of Turton, who never refers to the specimen, is entirely inaccurate, as the following statement will prove.
Columna figured a buffalo from Morocco. Pennant and Turton abbreviated his description and called it the dwarf buffalo and Bos
ee eee
Miscellaneous. 259
pumilus, thus making it the type of their species. The forehead and horns of a young ox were in the Museum of the Royal Society. Pennant thought that they belonged to his dwarf buffalo, but in his second edition said that he now found that they belonged to the Cape ox. Turton, in his account of Bos pumilus, made no reference to these horns, which Sir Victor Brooke says (but I do not think he has proved it) are the horns of a young Bos brachyceros of Western Africa, and proposes to change the name of this ox to Bos pumilus of Turton, established on an animal from Morocco, and not, as Sir Victor Brooke asserts in his paper, on the forehead and horns in the Museum of the Royal Society, the existence of which Turton does not notice. The animal from Morocco he named B. pumilus is supposed to be a young or dwarf variety of the common buffalo, and is certainly not the West-African bush-ox (Bos brachyceros).
If Sir Victor Brooke cannot see the mistake he has made, I have done my best to enable him to doso; andit is this non-appreciation of such questions that renders his prolix synonymy in various cases useless and misleading.
On Felis colocolo, Hamilton Smith, F. Cuvier, and Geoffroy. By Dr. J. E. Gray, F.R.S. &e.
Major Hamilton Smith made a figure of an animal “ said to have been shot in the interior of Guiana by an officer of Lewenstein’s Riflemen, and by him stuffed and sent to England, but which probably never reached its destination.” It is represented as a white cat, with various-sized longitudinal brown dashes on its neck and body, with slate-coloured legs and feet, and a slender black tail with numerous white rings.
Of this drawing an account was published in Griffith’s ‘ Animal Kingdom,’ in Geoffroy and Cuvier’s ‘ Histoire Naturelle des Mammi- féres’ (where the animal is said to come from Surinam), and in Jardine’s ‘ Naturalist’s Library,’ iil. p. 256, pl. xxvi., where the legs are erroneously left pale-coloured, though said to be blackish in the description.
I have never seen this cat, and I am not aware of its ever haying been seen or of its being in any museum in Europe. It certainly is not the Felis colocolo of Molina, from Chil, figured by Philippi, Wiegmann’s ‘Archiv,’ 1870, p. 41, t. 1. fig. 7, and t. i. figs. 1 & 2.
My late friend and teacher, Colonel Hamilton Smith, drew animals most beautifully and with great facility, and made a very large col- lection of sketches and drawings of them and of antiquities and costumes, which he collected from museums that he visited, and books, and even ‘fragments of skins. Unfortunately, instead of drawing the specimen or the figure of the animal which he examined as it was, he had the habit of improving its attitude, and even of making a beautiful drawing from a bad specimen, or from a fragment of a skin, or from a rough sketch, or from a woodcut or other figure which he found in some old book; and he very often did not mark his drawings whence or how they were obtained ; so

that it was difficult to tell their anthority. He seldom finished or coloured his sketches at the time he made them, but would mark on the parts of the drawing with the colour that they ought to be (as “red,” “white,” “ black”) without indicating the shade. This explains why the figures which are taken from his sketches in the first volume of Jardine’s ‘ Naturalist’s Library ’ (1842) were so erro- neously coloured, and makes the determination of some of his figures doubtful. It was this defect that rendered his beautiful and exten- sive series of sketches of so little value to the zoological student.
On some Remarkable Egq-sacs on an Annelid from the North Sea. By Prof. Karu Mostrvs.
Several specimens of Scolecolepis cirrata, Sars, were captured in the expedition of the ‘ Pommerania’ on the 6th August, 1872, at a depth of 69 fathoms, to the north-east of Scotland. This worm belongs to the family Spioidei. The body-segments are 2-4 millims. broad and 4 millims. deep; they have on each side a foot composed of a large upper and a smaller lower lamina. On the 28 segments of the fore body linguliform branchiz with long vibratile cilia are placed at the inner border of the upper foot-lamine. The hinder segments have no branchiz. All the segments bear long pointed sete both on the upper andlower foot-plates; on the lower lamin of the hinder segments there arealso uncini; and below and between themsomesmall pouches, having the form of a swallow’s nest, are attached. Many of these pouches contain a round mass of eggs, which often projects far beyond the orifice of the pouch. The eggs protruding from the pouches are held together by a net with quadrangular meshes, formed of cords of extremely fine threads. Before the pouches are filled with eggs this net lies in part like a lining within its pouch, and in part on the skin of the worm between the foot-laminz. As the latter contain many mucus-glands with fine orifices opening externally, we may assume that these glands form the net. The eggs are produced in the body- cavity of the worm, and issue through apertures which traverse the body-wall between the lower foot-lamine ; they then lift the ready prepared net from the skin, and are retained by it upon the body of the worm. The young animals which are developed from the eggs can slip out into the water through the meshes of the net.
We know of many Polychzetous Annelids which bear their eggs and young in a sac attached to the ventral surface (e. g. Autolytus prolifer, Miill.), one which carries them on the shorter dorsal fila- ments of its feet (Syllis pulligera, Krohn), and one which conceals them beneath folds of skin, developed on the peduncle of the oper- culum with which it closes its tube (Spzrorbis spirillum, Pagenst.) ; but the peculiar arrangement for the protection of the progeny seen in Scolecolepis cirrata was previously unknown.—WSchriften des naturwiss.

XXXIV.—On the Annelida of the Gulf of St. Lawrence, Canada. By W. C. M‘Intosu.
Family 1. EupHROSYNID&, #0 Family 6. SIGALIONIDA. [Plates IX. & X.]
THE following remarks are due to collections made by Mr. J. F. Whiteaves of Montreal during three dredging-expeditions (1871, 1872*, and 1873) in the Gulf of St. Lawrence; and I am much indebted to him for his courtesy in forwarding the specimens for examination.
No example of the first two families, viz. the Euphrosynide and Amphinomide, occurs. The Aphroditide are represented by several young examples of Aphrodita aculeata, L., which are of a somewhat ferruginous hue, like some Zetlandic spe- eimens. The ventral bristles of these young forms resemble those of A. alta, Kinberg. One or two examples of Letmonice filicornis, Kbg., a species very abundant in certain parts of the British seas, are also present. The Polynoide are more numerous, and the majority of comparatively large size. Lepidonotus squamatus, L., is abundant; and the same may

be said of Nychia cirrosa, Pall. The specimens of the latter have somewhat rougher scales, and a tendency to a longer and more slender tip in the ventral bristles than the British forms. The latter feature is carried to a characteristic degree in Nychia Amondseni, Mgrn., a northern species (not yet discovered in British waters) rather plentiful in the collections. In this form the head differs from that of N. cérrosa chiefly in the smaller size of the eyes, especially the posterior pair. The dorsal cirri are longer; but the dorsal bristles are similar, ex- cept, perhaps, that the contrast between the shortest and the most elongated is better marked. The ventral bristles are much more attenuated at the tips throughout ; and the smooth portion, while little longer in the superior series (though, of course, much more slender), becomes remarkably elongated in the central and lower groups. A specimen of Selenium poly- noés, Kroyer, was attached to the ventral aspect of a foot.

occurred on Orphan Bank, and is distinguished roughly from the more common L. nodosa, Sars, likewise in the collec- tion, by the brighter brownish coloration in spirit, by the much rougher scales, and the greater length of the dorsal bristles. Malmgren’s figures are much in need of amendment, especially his representation of the dorsal bristles.
Lagisca rarispina, Sars, var. occidentalis *.
At first sight, and with an imperfect specimen without scales, the form was considered closely allied to Polynoé floc- cosa, Say. ; but further examination of more perfect examples showed the true character of the annelid. ‘The scales are distinguished by the remarkably long, brownish, soft papille posteriorly, and have many parasitic Lowosome and other structures. The cilia on the dorsal cirri are much less nume- rous and shorter than on the species from the ‘ Porcupine’ (Lagisca Jeffreysii) ; and the ventral cirri have a few short papille: the latter are stated by Malmgren to be subglabrous. The dorsal bristles (Pl. IX. fig. 1) are rather long, tapered towards the point, and with somewhat fine rows of spikes. The smooth part at the tip is of moderate length ; but it often seems longer than it really is, since the rows of spikes pass far up; in certain views it is also slightly dilated, so as to give a character to the bristles. The superior ventral bristles

(Pl. IX. fig. 2) have elongated tips with a trace of a secon- dary process ; and the spiniferous region is long. The smooth tip becomes more boldly marked inferiorly (PI. LX. fig. 3) ; but the secondary process is always a mere rudiment, except, perhaps, in some of the young bristles inferiorly, or in those specially protected (e.g. Pl. LX. fig. 4). The general cha- racters of the form agree with LZ. rarispina; but the bristles differ considerably from Malmgren’s representations. ‘The young forms do not show the cilia on the ventral cirri—an absence which may have been due ocgasionally to position ; but the want of the characteristic elongated processes on the scales of such is peculiar.
Malmgrenia Whiteavesii *, n. sp.
A single small specimen about } inch long occurred between Anticosti and the Gaspé peninsula in 110 to 221 fathoms. The segments are about twenty in number, and the feet deeply eut; scales absent. The head is apparently eyeless. Antenne, palpi, and cirri smooth and much tapered. The dorsal cirri do not extend beyond the tips of the bristles ; the ventral reach the bases of the latter. The dorsal branch of the foot bears a series of rather slender, elongated, translucent bristles with fine serrations and a characteristic tip (Pl. IX. fig. 5); a few next the body are short and more boldly serrated. ‘The vén- tral form two sets,—a superior and larger group of delicate elongated bristles with tapering tips, minutely bifid at the extremity (Pl. IX. fig. 6); the tips gradually diminish to- wards the inferior border of the series, the whole, however, being bifid. At the ventral edge another, small group of stouter bristles exists, the number being variable, generally from six to eight: the enlarged tips of these are serrated for the lower half; then the smooth tip diminishes to a hooked point (Pl. IX. fig. 7).
Antinoé Sarsi, Kinb.
This species is not uncommon in the gulf. The scales have cilia on their posterior and outer borders, and small conical spines. The much elongated and tapered dorsal cirri have rather short clavate papilla continued almost to the tip of the organ. The ventral cirrus has shorter cilia of a similar shape. The dorsal bristles are distinctly curved, and have somewhat wide and prominent rows of spines, so that in some positions the more slender forms resemble stems of the common gut- setum. The superior ventral series of bristles have capillary

tips of extreme delicacy; a few in the centre of the foot are stouter, while the shorter ventral forms have again a capillary termination. <A parasitic Loxosoma occurs on the bristles.
Eupolynoé occidentalis, n. sp.
A fragment of the anterior end was procured in 110 fathoms between Cape Rosier and Cape Gaspé, so that only an im- perfect description is at present attainable. It is a large form, with comparatively short feet and slender bristles.
The head is dull purplish, two eyes being placed at the posterior and outer part, and two larger in front on the lateral prominence. ‘Tentacle absent ; antenne slender, subulate, and furnished with clavate papille. Palpi brownish, with minute though rather elongated papille. Tentacular cirri tapered, with numerous large clavate papille. A single dorsal cirrus only was found loose on the dorsum; it was filiform, gently tapered from the base to the point at which the more rapid nar- rowing of the tip occurs. ‘The base is covered with a dense series of long papillee, which exceed the diameter of the organ ; they are shorter towards the tip. The long papille are re- markably slender, uniformly cylindrical, with a slightly bulb- ous tip. The ventral cirrus tapers from base to apex, and is nearly smooth; a few short papille, however, are visible in some. ‘The ventral papilla is well marked and nearly cylindrical.
The dorsal bristles are rather small, not much tapered to- wards the tip, which is somewhat blunt and peculiarly curved (Pl. [X. fig. 8, one of the longer forms). The rows of spikes continue nearly to the tip. One of the stouter forms is given in fig. 9.
The ventral bristles are brownish rather than yellow, and are grouped in three series. ‘The upper are rather slender, have elongated, tapered, spinous tips, which terminate in a slender fork, a modification of the normal structure (PI. IX. fic. 10). Some have the fork even more slender and elongated than represented in the figure; others, again, have a shorter and stouter fork (Pl. IX. fig. 11). The next series have shorter tips and somewhat stouter shafts, the tips generally being evidently bifid (Plate IX. fig. 12). The latter repre- sents an average example, some having a more elongated, others a shorter and less distinct fork. The inferior series, again (fig. 13), all have stout shafts and simple tips, the curves of these and their general contour showing progressive changes from series to series.

Eupolynoé anticostiensts, n. sp.
Dredged rather abundantly in various parts of the Gulf of St. Lawrence in 1873. Distinguished under the naked eye by the somewhat elongated and flattened cylindrical body, covered with curiously mottled brownish scales with a distinct median spot.
Head with two eyes situated near the posterior border, and two under the outer margin of the somewhat pointed anterior lobes, so that they are not seen from the dorsum. The tentacle has a filiform tip, and the tentacular and dorsal curi are fur- nished with rather short but very characteristic clavate papille. The palpi likewise terminate in a filiform tip, and have minute papille sparsely distributed. The ventral cirri are short, scarcely reaching the base of the bristles, and with a few short clavate papille. The tips of the dorsal cirri also scarcely reach the tips of the bristles. The caudal styles are somewhat short.
There are fifteen pairs of scales, covering the body completely from head to tail; they are small in front, and increase in size posteriorly, the last pair being the largest as well as the most ovoid. From the brownish spot in the centre a curved brown- ish band, minutely speckled, proceeds inwards, sweeps round the posterior border, and terminates at the outer edge. This gives the dorsum of the perfect animal the characteristic ap- pearance formerly noted. They are nearly smooth, with the exception of a few short papille on the surface.
The dorsal branch of the foot has finely tapered and boldly serrated bristles, somewhat like those in Nychia (Pl. X. fig. 1). Some shorter forms occur next the body (Pl. X. fig. 2). The ventral division has superiorly a group with extremely elongated tips, some of which, however, are minutely forked if careful investigation is made (Pl. X. fig. 3). The tips gra- dually diminish in length and increase in stoutness, the bifid end having a broad and rather blunt terminal hook and a well- marked secondary process inferiorly (Pl. X. fig. 4).
There are considerable differences between this and the for- mer species ; but in the present state of the Annelida complica- tion in names is to be avoided.
Nemidia (?) canadensis, n. sp.
Body somewhat elongated, consisting of about forty-eight segments exclusive of head and tail. The head has four eyes, which hold a somewhat median position—that is, leave a con- siderable space in front and behind the pairs. he anterior pair, as usual, are larger. The palpi are smooth; tentacle and

cirri short, the latter having small and sparsely distributed papille. The dorsal cirri do not quite reach the tip of the bristles, while the ventral do not extend beyond the base of the lowest bristles. A conspicuous row of brownish papille runs along the centre of the dorsum.
The scales are small, occupying only the lateral region of the body, and leave seventeen segments uncovered posteriorly. Their number seems to be fifteen pairs ; but in none were they complete. They are more or less circular throughout, and have only a very few short papille on the posterior and outer edge.
The dorsal branch of the foot bears a series of rather short slender translucent bristles, very finely serrated (Pl. X. fig. 5). The superior series of the ventral group have elongated tips ter- minating in a fine point (PI. X. fig. 6). The spiniferous rows are elevated on scale-like processes, as im certain forms de- scribed in the ‘ Porcupine’ collection, with the free edges finely pectinated. The shaft of these bristles is quite smooth, while the dilated terminal portion is marked by fine longitu- dinal lines. The foregoing are succeeded by a stouter series with shorter tips (Pl. X. figs. 7 & 8), with only five or six conspicuous rows of spines, while the tip ends in a stout slightly hooked point. The first of the series has a more slender point, and with the others distinguish the species from Malmgren’s N. Torelli. At the extreme ventral edge, again, a few slender bristles with finely tapered tips occur.
Nemidia (?) Lawrencit, n. sp. -
In this form the scales are tolerably large and cover the back entirely, except anteriorly in the region of the fourth and fifth pairs. ‘The segments number about 38.
The head is elongated from before backwards, and the pointed anterior lobes diverge in a characteristic manner. The eyes are small—a pair situated near the posterior border, and a larger pair on the lateral region in front of the middle line. Tentacle somewhat slender. Palpi furnished with distinct clavate papille. Tentacular and dorsal cirri with short cla- vate papille. The short and tapering dorsal cirri scarcely reach the tip of the bristles. The ventral cirri seem to be smooth.
The scales are somewhat ovoid, and nearly reach the poste- rior extremity of the animal, which has two long tapering caudal styles. They are almost smooth, a very few minute papilla only occurring at wide intervals. Their number appears to be about fifteen pairs. Four bristled segments
te ds,

exist between the posterior border of the last scale and the tail. The superior branch of the foot has a series of pellucid bristles, somewhat stouter on the whole than in N. canadensis, and with bolder characters (Pl. X. fig. 9). They are finely serrated towards the tip, a feature which attains much more development in the shorter and stouter forms than in N. cana- densis. The superior ventral bristles have long tips with somewhat less prominent rows than in NV. canadensis ; and the end is less capillary, though it is finely pointed (Pl. X. fig. 10). The larger size of the bristles also in the specimens brings out thé smooth portion at the tip more distinctly. The tips in the succeeding forms are stout and sharply pointed, and the spined portion shorter and less prominent (Pl. X. fig. 11). The sabre-shaped tips of the latter are prominent features. This and the foregoing agree in certain respects both with Enipo and Nemidia, Malmgren. In regard to length of body they approach the latter, which, however, he describes as eyeless. The dorsal cirri, again, in Enzpo are smooth. In British spe- cimens which I have referred to the latter there are a few peculiarly bifid bristles besides the forms mentioned by Malm- gren in the ventral group. In the foregoing Canadian examples the tips of all the bristles are simple.
Polynoé gaspéensis, n. sp.
Dredged in 100 to 212 fathoms off Anticosti and in various parts in 1872. A long and highly characteristic form, with fifteen pairs of smooth scales, the first pair only touching each other in the median line, the others being separated by a considerable bare portion of the dorsum; they are translucent, and slightly tinged of a brownish colour in spirit towards the inner border. ‘The first pair are larger, and have their pigment more diffused though not more dense. In shape the first pair are ovoid ; and the rest maintain a similar outline, but gradually diminish in size. ‘The fifteen scales occupy thirty-one bristled segments, the last occurring on the thirty-first. In a large specimen there are thirty-seven segments behind the last scale, each bearing a dorsal cirrus as in the case of those in front without scales.
The head is furnished with two eyes placed some distance in front of the posterior border, and two (as usual, somewhat larger and wider apart) at the anterior border. ‘Tentacle long, brownish, the colour being deepest just below the tapering tip, which is pale; a very few slender papillz occur on this organ. Palpi also brownish, with pale tips, densely covered with short clavate papilla. Antenne short, brownish, with pale
268 Dr. W.C. M‘Intosh on the Annelida
tapering tips, sparsely furnished with short clavate papille. The tentacular and dorsal cirri have similar clavate processes ; and the latter extend rather beyond the extremity of the bristles. The ventral cirri have also a few small clavate papille. The papilla at the inner end of the foot 1s some- what elongated.
The feet are well marked, though somewhat thick and short. The bristles of the dorsal tuft are short (Pl. IX. figs. 14 & 15). The ventral series consist of one kind, with a stout shaft and a simple tip (Pl. X. figs. 12 & 13). There are comparatively few rows of spikes. The former figure is from the middle of the group, the latter from the superior border. The spine at the base of the smooth tip is well marked in the last mentioned.
The family of the Accetidee has no representative ; but four examples of the next, the Sigalionide, occur. The first is Sthenelais limicola, Ehlers, a northern species having avery wide distribution. ‘The second is Leantra tetragona, Cirst., which was met with in 1872 off Cape Rosier in 110 fathoms on coarse sand and stones, and in 110 to 221 fathoms between Anticosti and the Gaspé peninsula in 1873. The form is distinguished by its Sigalion-like appearance ; but the bristles of the feet have simple tapering tips. ‘The antenneze are repre- sented by short processes at the side of the tentacle; and no eyes are visible in spirit-preparations. The scales are pellucid, reniform, and furnished with rather long and nearly cylindrical papille, the tips of some of which are obscurely bifid ; the rest of the margin is smooth. The superior lobe of the foot bears long bristles with wide rows of spikes, while the basal portion is smooth. A group of long papille project from the upper margin of the foot, and occasionally a few are obscurely bifid. Similar organs occur on the inferior lobe. The whole of the bristles of the latter have taperig filiform tips, with appa- rently a spiral series of markings. The shafts and tips of the superior ventral series are, as usual, stouter than the inferior ; but the diminution is not quite uniform, as a strong group occurs just above the most delicate ventral series. ‘The ven- tral cirrus is well developed, but does not quite reach the tip of the foot. There are three ciliated pads on the dorsal edge below the branchial process. Another Leanira, apparently differing from any yet described, though allied to L. Yhlend, Mern., was procured in 1875 in 210 fathoms off the S.W. point of Anticosti. None of the examples are complete; but it seems to attain a length of 2 or 3 inches.
The head is at once distinguished from Z. levis of the ‘ Por-
of the Gulf of St. Lawrence. 269
cupine’ expedition (a species also having smooth scales) by the condition of the median tentacle, which with the other parts conform to the arrangement in L. tetragona. The scales are delicate, translucent, irregularly rounded in front, reniform posteriorly, and perfectly smooth round the margin. The dorsal bristles have, perhaps, more closely arranged rows of spikes than in L. levis. The inferior bristles (Pl. X. fig. 14) have delicately tapered tips, with faint spiral indications in- ternally. The latter differ, of course, according to the position in which they are viewed. The ventral cirrus is considerably longer than in L. tetragona or L. levis; and the digitate ap- pendages of the lobes of the feet also differ from both. Dr. Malmgren states that his LZ. Yhleni has distinct eyes, and adds that (with the exception of the smooth scales) it agrees with L. tetragona. His notice is so very brief that it is impos- sible to distinguish forms so closely related to each other. The fourth species of the group is the common Pholoé minuta, Fabr., which has a wide range.
Several remarks on the Annelida of the neighbouring shores of the United States have been made. Amongst others Dr. Stimpson, in his ‘ Synopsis of the Fauna of Grand Manan in the Bay of Fundy,’ mentions Huphrosyne borealis, CErst., Cryptonota citrina, n. sp., Lepidonota cirrata, CErst., L. punc- tata, (irst., and L. scabra, Cirst. The second is probably a Spinther ; the next two are doubtful ; and the third is Nychia cirrosa, Pallas. Dr. Leidy *, again, considers L. punctata of the former author to be another species, which he terms Z. ar- madillo, Bosc; it has dilated cirri, with a black ring, but differs from L. clava, Mont., in having cilia on its scales. He also states that Sigalion mathilde, Aud. & Edw., is found on these shores ; but the figure of the head given (fig. 53, pl. xi.) shows the prominent median tentacle of a Sthenelais; so that some other form is meant. In his recent paper Prof. Verrill indi- cates “ Hermione hystrix(?)” as formerly noted, and “‘Antinoé
Sars,” Kbg.

This genus differs from the other Anisodactyline in the form of its head and mandibles, which resemble those of Phor- ticosomus, Cratacanthus, &c.; but the eyes are rather promi- nent; the suture separating the epistome from the forehead is very sharply impressed, and has a short deep frontal foveole near each end. The paraglosse are lateral, and not placed behind the ligula, as in other genera of the group.

Castelnau’s description applies to the species as far as it goes, except the size (5 lines). My specimens came from Mr. Henry Edwards (from Auckland?) and Mr. Fereday of Christchurch.
Lecanomerus latimanus, n. sp.
L. ovatus, piceo-fuscus, modice nitidus; partibus oris, antennis, pedibus, elytrorumque marginibus (postice dilatatis) fulvo- testaceis; thorace transversim quadrato, yix postice angustato, angulis posticis rotundatis, supra basi levi haud foveato ; elytris ovatis, convexis.

Long. 23 lin. ¢.
The form of this curious insect is that of an Odpterus, the elytra being ovate (much broader than the thorax) and convex ; but the broad patelliform anterior and middle tarsi of the male, with their even, smooth brush-soles, show that it belongs to the Australian genus Lecanomerus (Chaud.). It agrees in all other generic characters with L. ¢nsidiosus ; but the second tarsal joint is shorter and more semicircular, and the fourth is much broader. The elytra in the unique specimen are dark pitchy brown with fulvous lateral margins, not very well

defined, but widening much at the apex; there is no puncture on the third interstice, and there is a short scutellar striole between the first and second striz. The margins of the ventral segments are more or less fulvous.
One example, from New Zealand. Obtained from the late Rey. Hamlet Clark’s collection.
Hypharpax antarcticus.
Harpalus antarcticus, Castelnau, /. e. p. 198.
Christchurch (Mr. Fereday).
Scarcely belongs to Hypharpax, the hind tibie of the male not being arcuated; in facies and in the long fine bristles on the innerside of the tibie, with a row of shorter spines on the outer side, it resembles that genus. Four joints of the four anterior tarsi of the male are dilated, and smooth, brush-like, beneath.
Hypharpax australasie. Harpalus australasie, De}. Sp. Gén. iv. p. 386.
Hypharpax australis. Harpalus australis, De}. 1. c. p. 385.
Both these species are found in New Zealand, according to Redtenbacher.
Although only the female in each case was described by Dejean, I think they belong to the genus Hypharpax.

EUTHENARUS, nov. gen.
Gen. Tachycello similis. Palpi robusti, glabri; articulo terminali fusiformi, versus apicem attenuato, apice leviter truncato. Antenne robuste; articulo undecimo multo longiore, crasso.

The insects on which this distinct new genus is founded resemble the Bradycelli and small Stenolophi of the northern hemisphere, but are widely different in the clothing of the four dilated palms of the male. This is unlike either the squame arranged in pairs of the true Harpalide, or the even brush of short vertical hairs of the Anisodactyline, but con-

sists of a few very long linear hair-scales set obliquely on the broad palms and forming a broad fringe to the feet. The paraglosse also differ from those of the Harpali in being very broad, not tapering to the apex, but broadly rounded. The frontal foveee of the head form short strize curving to the inner margin of the eye. The thorax is quadrate. The elytra are obtuse at the apex, with a strong sinuation; the scutellar striole is rudimentary between the first and second strie ; the third interstice has one puncture. The males have a hairy fovea in the middle of the first ventral segment, like the Tachycelli.
Euthenarus brevicollis, n. sp.
E. oblongus, fusco-zeneus ; elytris subcupreis ; antennis basi, palpis apice, genibusque piceo-rufis; thorace postice paululum angustato, angulis posticis obtusis fere rotundatis, fovea utrinque lata sparsim punctulata ; elytris acute striatis, interstitiis planis. Long. 23 im S92 Lake Coleridge; under stones in dry lagoon (C. M. Wake-

Immature specimens have testaceous-yellow legs and pale under surface of body ; but the dark brassy colour of the head and thorax and cupreous elytra remain in all the numerous individuals sent. ‘The hind angles of the thorax are distinct in some examples and perfectly rounded off in others; the basal fovex also vary in the amount of punctuation, which is always rather coarse.
Euthenarus puncticollis, n. sp.
E. oblongus, fusco-piceus seneo tinctus vel cupreo-sneus; antennis basi, palpis basi et apice, pedibus (femoribus interdum exceptis) rufo-piceis ; thorace longiore, postice subsinuatim paulo angustato, angulis posticis fere rectis, fovea basali grosse punctata; elytris apice fortiter sinuatis, subtruncatis. Long. 23 lin. ¢g 9. Apparently distinct from /. brevicollis, although similar
in size and coloration. It is decidedly slenderer, with longer
thorax, the posterior narrowing of which is slightly incurved and the hind angles more distinct. The general colour is less metallic; and the side rims of the thorax are pale, which is sometimes the case with £. brevicollis. A better distinction is the more transverse and stronger sinuation of the apex of the elytra, the edges external to the sinuation being more flattened out; they are finely and sharply striated in the same manner.

White’s description omits all the essential characters of this curious Carabid, and is so vague that there are no means of identifying it without reference to the type. I have seen a specimen so named in the British Museum, which quite agrees with Sphallax peryphoides. ‘The extraordinary form of the ligula, and other characters, necessitate the formation of a new subfamily for the imsect, which will range near the Oda- canthine.

Chaudoir’s name must remain for this species, according to the rule that the first unoccupied name accompanied by a description takes the priority. The figure in the ‘ Voyage au Pole Sud’ was published eleven years before the description, and was erroneously lettered C. australis, not beimg the C. australis of Dejean. Blanchard himself corrected this error in 1853; but long before that date Chaudoir’s excellent description had appeared. White’s name was simply given (without description) to the above-mentioned figure, in place of the erroneous C. australis.

XXXVI.—Remarks on Mr. H. J. Carter’s Letter to Prof. King on the Structure of the so-called Kozoon canadense. By Wituram B. Carpenter, M.D., LL.D., F.R.S., Corre- sponding Member of the Institute of France.
Tue well-merited reputation which Mr. Carter has gained by his researches on Sponges and Foraminifera will doubtless give to his decided expression of opinion against the Forami- niferal character of the (so-called) Hozoon canadense a very considerable weight with those naturalists who regard the question as still sub judice.
Had Mr. Carter (whose additions to our knowledge of the minute structure of certain types of Foraminifera are estimated by no one more highly than by myself) pronounced this opinion after a careful study of what has been written cn javour of the Foraminiferal character of Hozoon, and after an examination of the pieces justificatives therein referred to, I should have respected it, however different from my own, as that of an able investigator who has the fullest right both to form and to publish his judgment, and should not have troubled the scientific public with any further discussion of the ques- tion at issue.

278 Dr. W. B. Carpenter on the
But that the readers of Mr. Carter’s letter may form a right estimate of the value of his pronunctamento, they ought to be aware of the following facts :—
1. Mr. Carter, as I learn from himself, has not read any thing that has been written upon the opposite side of the question.
2. Mr. Carter’s ideas of Foraminiferal structure are based, not upon a comprehensive survey of the entire group, but upon that of the small number of types he has himself examined. This is clear from the fact that his definitions (pp. 191, 192) apply only to a certain section of the Vitreous or ‘ perforate” Order, and exclude the Porcellanous and the Arenaceous Orders—the first of them uniformly “ imperforate,” the second generally so.
3. Mr. Carter’s knowledge of Hozoon is avowedly confined to that which he has derived from the examination of the spe- cimens sent to him by Prof. King. If he had asked me to show him the chief results I obtained from a study of the large mass of material put into my hands by Sir Wm. Logan, which occupied nearly my whole time (during slow conva- lescence from a severe illness) for a space of two months, I should have most gladly done so; and I feel sure that I should at any rate have demonstrated to him that there is a great deal more to be said in favour of the Foraminiferal nature of Eozoon than he has at present any idea of.
Hence Mr. Carter’s affirmation, that the opinion of those from whom he differs on this question has no other basis than “the wildest conjecture,” and his imputation to them of inca- pacity to distinguish things as different from each other “as the legs of a table are from the legs of a quadruped,” are to be considered simply as specimens of a new method and lan- guage, which, after Prof. Huxley *, I may term Carterese. Whether its general adoption will be good for the progress of Science, may be an open question: I will give an example of its application.
Geologists who have worked over the Greensand near Cam- bridge, have met with spherical bodies varying from the size of a marble to that of a small cricket-ball ; which, I learn from Prof. Ramsay, they were accustomed to kick about as inor- ganic concretions, without the smallest idea of their organic origin. ‘The discovery by Prof. Morris, however, of a non- infiltrated specimen, led me to examine the internal structure of these solid balls; and this examination brought me to the knowledge of the entirely new and, in many particulars, ano-

Structure of Eozoon canadense. 279
malous type of Foraminiferal structure, formed by the cemen- tation of sand-grains in concentric spheres, which I have de- scribed under the name Parkeriva (Phil. Trans. 1869). But as this type does not happen to conform to Mr. Carter’s pre- conception of a Foraminifer, and as he might examine one or more of the silicified balls without finding any indication of organic structure, the principle on which he has acted in re- gard to Hozoon would justify him in asserting that nothing but the “wildest conjecture” could make it out to be Fora- miniferal, for that “its structure does not bear so much resem- blance to that of a foraminiferous test as the legs of a table to those of a quadruped.”’ Now it so happens that every con- clusion I had drawn from the careful study of the best-pre- served specimens of Parkeria has been fully confirmed, and its anomalies explained, by the discovery, in our Deep-sea dredgings, of a living Arenaceous Foraminifer (with the animal in it), whose structure conforms, in all essential par- ticulars, to that of Parkerta. I may fairly, then, apply Mr. Carter’s words to his own method, and say that, “if such be the grounds on which geological inferences are established, the sooner they are abandoned the better for geology, the worse for sensationalism.”
Those whose knowledge of Foraminifera ranges over the entire group as at present known, have the most unlimited belief in its “‘ possibilities ;”’ and it has thus come to pass that they accept the Foraminiferal character of the Hozoon, on the basis of the large number of parallelisms which its structure presents to that of existing types, notwithstanding some dif Jerences, which they regard as comparatively non-essential.
To say nothing of my collaborateurs, Mr. W. K. Parker, Prof. 1. Rupert Jones, and Mr. H. B. Brady, whose opinions may be thought to have been personally influenced by my own, I may cite the judgment recently given by the late Prof. Max Schultze not long before his lamented death, as that of an entirely unprejudiced and fully competent “ third party,” whose opinion even Mr. Carter is bound to respect, on account not only of his well-known profound mastery of Zoology generally, but of his special knowledge of Foraminifera—his admirable Treatise ‘ Ueber den Organismus der Polythalamien ’ having been referred to in my ‘ Introduction to the Study of the Foraminifera’ (1862) as “among the most important of recent contributions to our knowledge of the organizdtion and life-history” of the group. In the spring of last year, Prof. Schultze requested me to send him some specimens of Hozoon, in order that he might form his own judgment of its nature,
at the same time stating the general opinion among German 20*

geologists to be adverse to its organic character. In response, I forwarded to him two specimens—one a transparent section taken from the same block as that which furnished the section examined by Mr. Carter, the other a decalcified slice. Sub- sequently, at his request, I sent him the largest specimen of Eozoon I could spare en bloc, that he might make preparations for himself. The result of his examination of these specimens was to satisfy him completely of the Foraminiferal character of Eozoon*. This conclusion was formed without any “ verbal arguments ”’ or ‘ prolonged disputations,” but on the basis of Prof. Schultze’s own “actual comparison of specimens”’ of Eozoon with specimens of recent Foraminifera—the former showing the very structures which Mr. Carter could not find in the specimens he examined, and the latter exhibiting those precise parallelisms which the recent types referred to by Mr. Carter do not furnish.
I shall now briefly state what these parallelisms are.
1. Large masses of rock occur in the Laurentians of Canada, in which there isa very regular alternation of lamellee of Carbonate of Lime (sometimes replaced by Dolomite) with lamellee of Serpentine or some other Magnesian Silicate, often to the number of fifty or more. For this alternation, such eminent Petrologists as Dr. Sterry Hunt and Mr. Sorby have expressed their inability to account on any known principles of Mineralogical formation; on the other hand, it becomes perfectly intelligible when we view the calcareous lamellz as having been successively formed by the growth of a Foramini- feral shell, and the serpentinous lamelle as having been sub- sequently produced by the replacement of the sarcodic body which occupied its cavities by a deposit of serpentine or some other silicate; for such replacement ¢s going on at the present time, so as to furnish us with internal casts of various Horami- nifera brought up by dredging from the ordinary sea-bottom— these internal casts giving us (when the calcareous shell is dissolved away by dilute acid) the perfect models, not merely of the segments of the sarcodie body, but also of the sarcodic ramifications of the canal-system, and even, in some instances, of the sarcodic threads filling the minute tubuli of the shell-
wall. Even so, when the calcareous lamelle of Hozoon
* Referying to the sections I had sent him, Prof. Max Schultze said, in a letter dated Aug. 16, 1875, “‘Some points are very difficult to settle ; but the organic structure cannot be doubtful.” And after making his own investigation on the piece I had subsequently sent to him, he said, in a letter dated Noy. 15, 1875, “In the last number of the ‘Comptes Rendus’ of the Association of Wiesbaden, I gave a short extract of my researches on Eozoon, quite accordant with yours.’ A translation of this report will be found in p. 524.

were first pointed out by Professor Ehrenberg as exhibited in the Green-sands of various Geological periods, with details which accord most remarkably with those of particular types.
2. Although, in its indefinite zoophytic mode of growth, Eozoon differed from the Nummulites and Orbitoides to which Mr. Carter refers, yet it agrees with Polytrema*, a type which was formerly described as a Millepore, but which I have shown to be a wildly-growing Rotalian. Further, in its im- perfect segmentation, only interrupted occasionally by a com- plete chamber-partition, it agrees with Carpenteriat, another Rotalian ; my description of which, as of the preceding, and my references to them in my account of Hozoon, it is of course only consistent in Mr. Carter to ignore, on his principle of not reading any thing on the other side.
3. The general plan of the Calcareous fabric, as we should see it if we could dissolve out the Serpentine, is shown in fig. 2, which was constructed from sections in my possession by the conscientious and intelligent draughtsman Mr. George West, to whom I was indebted for those admirable constructive representations of various types of recent Koraminifera whose accuracy no one has ever challenged{. ‘This shows the suc-

{ A most remarkable proof of this accuracy was afforded by the fact that Mr. G, West’s reconstruction of the complicated canal-system of Polystomella (‘Introduction to the Study of the Foraminifera,’ pl. xvi. fiz. 1) was made four years before I obtained the internal cast (fig. 9), which verified it to the minutest particular.

cessive stories of chambers (A’ A’, A* A”), the chambers of one story usually opening into one another like apartments en suite, but being occasionally divided by complete septa traversed by passages, as at b 6. Each chamber is enclosed in a chamber-wall, BB, which, when well preserved, alike in sections and in internal casts, exhibits a fine nummuline tubulation, generally perpendicular in its direction, but fre- quently presenting exactly those varieties which I have figured and described in the tubulation of the recent Operculina. I freely admit that there are two anomalies in the arrangement of this tubulated chamber-wall :—first, that it covers the floor, resting on the preformed intermediate skeleton, as well as - forms the ceiling ; and, second, that its tubulation is sometimes horizontal. But looking to the wonderful variability of the Foraminiferal type, and the number of the parallelisms exhi- bited in the calcareous structure here represented to the known
Structure of Hozoon canadense.
forms of Foraminiferal organization, I ask whether, in the face of the continual discovery of far more strange anomalies (as in the case of Parkeria), these entitle any one to affirm that this structure is a mere pseudomorph. If the accuracy of that representation is questioned or denied, I have simply to say that I can prove it to any one who will examine the _ preparations in my possession.
4, The “intermediate skeleton” (fig. 2, C C) precisely corresponds in its disposition, and in the distribution of the canal-system (E) which traverses its thicker layers, with the intermediate skeleton of Calcarina, another type fully eluci- dated by me, to which Mr. Carter makes no. reference ; and there is this further very curious correspondence—that the
Structure of EKozoon canadense. 283
canal-system originates, not directly from the chambers, but, as in Calcarina, trom a set of sinuses outside the tubulated chamber-wall. Now Mr. Carter seems to suppose that Dr. Dawson, and all those who agree with him in this identifi- cation (which Dr. Dawson first made by comparison with specimens of Calcarina he had received trom myself), have been so “ green” as never to have thought of the probability that the so-called canal-system may be nothing else than dendrites of glauconite. This hypothesis has from the first ‘been present to our minds, as Mr. Carter would have seen if he had read the memoirs which he has thought fit to ignore. And, not to mention other reasons, I may state two, which perfectly satisfy Mr. Sorby (the most eminent authority on micro-mineralogy) that they cannot be thus accounted for. First, these dendrites usually pass directly across the cleavage- planes of the calcareous shell, between which, if they were infiltrations, they would be almost certain to spread. Second (and this is, to my mind, still more conclusive), that minuter part of the canalicular system which is only to be discerned in the very transparent calcite by a careful management of the light (and which Mr. Carter has obviously not recognized), is not infiltrated with any foreign mineral at all; but is simply filled up with calcite, disposed in the same crystalline axis with that of the shell itself, as is the case in the consolidated calcareous network of the fossil spines of Echinida, the stems of Crinoidea, and the like. An experience of thirty-five years, extending over a wide range of Micro-paleontological inquiry, has given me, I venture to think, some special apti- tude for recognizing Organic structure when I see it; and I never saw, in any fossil whatever, more distinct evidences of organic structure, than are to be seen in these finer ramifica- tions of the canal-system of Hozoon, which are far more distinct than is the tubulation of any but the best-preserved fossil Nummulites.
I do not pretend to affirm that the doctrine of the Forami- niferal nature of Hozoon can be proved in the demonstrative sense. But Ido affirm that the convergence of a number of separate and independent probabilities, all accordant with that hypothesis, while a separate explanation must be invented for each of them on any other hypothesis, gives it that high pro- bability on which we rest in the ordinary affairs of life, in the verdicts of juries, and in the interpretation of Geological phenomena generally.
To any one who calls in question the evidentiary facts I have adduced, I simply say ‘Come and see.’”’ I cannot be

expected to trust out of my possession valuable preparations, which, if lost or injured, I might never be able to replace. But I am quite willmg to give time and trouble to enable those who wish to make the “ comparison of the actual speci- mens’ for themselves, to do so, without any ‘ verbal argu- ments ” or “ prolonged disputations.”
If the so-called Hozoon be really an Organic structure, whether Foraminiferal or any thing else, it is time that it should be generally acknowledged as such. But if it can be shown to be a Mineral pseudomorph, I quite agree with Mr. Carter that the sooner it is exploded as a sham, the better it will be for Geology. I trust that my scientific career has given suflicient evidence of my having “loved truth better than system,” to justify my assertion that I shall be quite ready to surrender it, if I can be proved to be mistaken (as I have been before now) by the examination of my own specimens, and that I shall even thank any one who will set me right. No one, however, of the many eminent scientific men who have ex- amined and compared these specimens, has as yet pointed out to me any error In my interpretation of the appearances they present; and nearly all of them have expressed their unreserved acceptance of it.
XXXVII.—On the Arrangement of Sponges. By Dr. J. E. Gray, F.R.S. &e.
I PROPOSED an arrangement of sponges in the ‘ Proc. Zool.
Soe.’ 1867, p. 502, of which I suggested a modification in the
‘Ann. & Mag. Nat. Hist.’ 1868, i. p. 165, and 1872, ix. p. 440,
and especially in a paper which I wrote on the division of the
, spicules of sponges into types (Ann. & Mag. Nat. Hist. 1873, xu. p. 203).
The continued study of the structure of sponges and of their spicules has induced me to propose an alteration in their arrangement, as a sequel to the last quoted paper, which I believe will make it more natural and facilitate their study.
I would divide the Porifera, or sponges, into four orders :—
Order I. Arenosponera (Ann. & Mag. Nat. Hist. 1872, ix. p- 448, enlarged). The sponges strengthened by particles of sand, fragments of spicules, and other siliceous bodies, which they collect from the sea.
Order II. THALAssosponaiA (Ann. & Mag. Nat. Hist. 1872,
Dr. J. E. Gray on the Arrangement of Sponges. 285
ix. p. 446). The sponge olive, formed of a fleshy or horny skeleton, and strengthened by regular siliceous spicules which are secreted by it; ovisacs membranaceous, scattered in the substance of the sponge.
Order [1]. Poramosponeta (Ann. & Mag. Nat. Hist. 1872, ix. p. 461). The sponge green; skeleton’ strengthened by regular siliceous spicules; ovisacs cartilaginous, strengthened by fusiform or birotate siliceous spicules. (See the divisions proposed in the ‘Annals’ above quoted, ». 461.)
Gact IV. CaucisponciA. The sponge strengthened by regular calcareous, generally three-rayed, spicules.
Order I. ARENOSPONGIA.
The sponges of this order, which vary in shape from being discoidal, massive, to dendroidal, are peculiar for collecting together the sand or fragments of spicules, which are abundant at the bottom of the sea, for the purpose of giving strength and consistence to their structure ; and these answer the same purpose as the siliceous or calcareous spicules which are secreted by the other marine and freshwater sponges. The quantity of horny matter covering the sand, and the quantity of sand enclosed by it, are very different in the different species of these sponges. It sometimes forms a thick, fibrous, horny skeleton, with only a single layer of sand in the centre of the fibre; and in some species this sand is only found in the thicker part of the horny skeleton. In other species the sponge seems entirely formed of sand merely kept together by a thin coat of horny matter.
In the arrangement I proposed in 1867 I placed the sponges of this group in two families, Dysideidee and Xenospongiade, placing the latter family in a subsection which I called sand sponges (Arenospongiade), and the other family with the Ceratospongia. But more mature consideration has induced me to increase the suborder Arenospongia and put them together ; for it is a very important element in the ceconomy of the animal that one family collects together the ready formed siliceous bodies, and the other secretes the siliceous or cal- careous spicula by which the body of the sponge is strength- ened.
This order consists of two families :—
1. Xenospongiade.
Sponges discoidal, strengthened with irregularly placed sand and fragments of spicules.
286 Dr. J. E. Gray on the Arrangement of Sponges.
2. Dysideide.
Sponges massive or dendroidal, formed of fibres constituting a more or less thick coat to the more or less abundant sand or fragments of spicules contained in their centre.
Dysidea and Halispongia, Bowerbank, Proc. Zool. Soc. 1872, t. vi.
The Xenospongiade are peculiar for having a series of very slender diverging filiform spicules on the circumference, and pencils of similar spicules on the mouth of the oscules on the upper surface of the disk, which appear very different from the spicules of other sponges both in structure and position ; and I am not aware that they have been observed in Dysideide. Some of the calcareous sponges have the oscule similarly fringed or bearded.
Order I]. THALASSOSPONGIA.
This is a very large and numerous group of sponges, cha- racterized by their secreting the siliceous spicules by which their body is almost universally strengthened ; but the number and form of the spicules very greatly vary in the different kinds. In some, as in the coral-sponges, the body is almost entirely formed of spicules which are united together by a deposit of siliceous matter on their surface, forming the whole into a hard siliceous coralloid body ; in others the sponges merely form a horny skeleton, containing one or more series of spicules in its central line. I am inclined to place the genus Spongia, which is formed entirely of a horny skeleton without any spicules, as an aberrant or abnormal form of this order, though perhaps we may find, when the habit and structure of these bodies are more known, that some species of true sponges (Spongia) are aberrant sand-sponges which do not collect sand, and other species are aberrant spicular sponges that do not secrete spicules.
The Thalassospongia may be divided into various suborders according to the spicules which they secrete, and whether they secrete spicules of all, of one, or of two or more of the types of spicules which I described in the ‘Ann. & Mag. Nat. Hist.’ 1873, xi. p. 203.
The sponges are all provided with more or less abundant simple subcylindrical spicules, which may be regarded as the basis of their skeleton; but some have spicules of one or more of the other types added to them ; and I am inclined to divide them into suborders according to the various types of spicules by which their body is strengthened ; and they often have free
Dr. J. E. Gray on the Arrangement of Sponges. 287
spicules scattered in the sarcode, which are generally of a small size and uniform shape, and are characteristic of each suborder. Thus they are hamate unilateral in the Hamispongia, sex- radiate in the Sexradiatospongia, and stellate multiradiate, in the form of spicular spherules, in the Quingueradiate group.
In the division of the marine sponges, like other natural bodies, into suborders or types the characters of the orders given are those of the general mass of species belonging to it ; but there occur genera or families that have most of the characters of the suborder or family but want the essential character of the group—as the genus Spongia, which belongs to the order Thalassospongia, but wants the characteristic siliceous spicules. In the same manner Placospongia has the spherical spicules of the quinqueradiate sponges, but appears to be without the quinqueradiate spicules; and the Chondrillade have the many-rayed spicules of the same suborder, but also want the five-rayed spicules—these groups being what Mr. MacLeay called “ aberrant types.”
Suborder I. LEIOSPONGIA.
The sponges only strengthened by simple, elongate, sub- cylindrical, fusiform spicules, tapering at each end, or enlarged, club-shaped, or capitate at one or bothends. This suborder is without spicules of the sexradiate or quinqueradiate types, or the free spicules peculiar to each.
This suborder contains many species, and requires much study to make out its structure, which I am glad to say Mr. Carter is bestowing upon it.
It contains :—
1. The Suberispongia, which are massive, with inosculating areolar cavities terminating in a vent on the surface—as Suberitide and Raphiophoride (‘ Annals,’ l. c. p. 447).
2. The Keratospongia, with a skeleton formed of reticulated horny fibres having one or more series of spicules in the central line—as Chalinide, Phakelliade, Halichondriade, and Polymastide.
3. The Ophistospongia, with a skeleton like the Keratospongia, but with diverging spicules on its outer surface—as Ophistospongiade (‘ Annals,’ /. c. p. 447).
Suborder II. Hamisponera (Ann. & Mag. Nat. Hist. 1872, ix. p. 448).
Sponges with unilateral spicules, which are curved at each end, and either subcylindrical or more or less expanded, in
288 Dr. J. EH. Gray on the Arrangement of Sponges.
addition to the fusiform, clavate, or capitate spicules of the former suborder.
This suborder consists of the family Esperiade (Proc. Zool. Soc. 1867, pp. 502, 532), except the genus Carteria, which proves to be a sexradiate sponge. Some genera have only the bihamate spicules ; but in general they have bihamate and contorted spicules.
In the ‘Ann. & Mag. Nat. Hist.’ (7. c.) I divided this sub- order into four families—Esperiade, Desmacidonide, Hama- canthide, and Gelliadee.
Suborder III. SexRADIATOSPONGIA.
Sponges with spicules of the sexradiate type, m combination with the simple spicules of the Leiospongia.
This suborder agrees with the Hexactinellide of Mr. Carter, so well described in the ‘Ann. & Mag. Nat. Hist.’ 1873, xi. p. 857, excluding the genus Hyalonema, and adding to it the genus Carteria, which Mr. Carter partly describes and figures under the name of Hyalonema.
In the paper in the ‘ Proc. Zool. Soc.’ for 1867 I formed the order Coralliospongia, and in the ‘Ann. & Mag. Nat. Hist.’ 1872, ix. p. 447, I considered “the hexaradiate spicules the essential character of the order” (see p. 449). It has since been found to contain a series of sponges which belong to the quinqueradiate type and are placed separate by Mr. Carter, a correction which I gladly acknowledge and adopt.
The radiating spicules which form the skeleton of the body are frequently of large size, and are modified in form accord- ing to the position which they occupy in the body. The lateral rays in perfectly developed spicules are generally equal ; but at other times one or more of the rays are only partially de- veloped. The shaft or central axis is frequently elongate, much longer than the lateral rays; but when the spicules are on the surface of the sponge the outer end of the shaft is more or less imperfectly developed, sometimes reduced to a single tubercle, and the other end of the shaft on the inside of the sponge is frequently much lengthened. The two ends of the shaft are almost always simple ; but the lateral rays, especially of the quinqueradiate type, are frequently forked.
The sexradiate spicules which are scattered in the sar- code, and consequently free from each other, are always of a much smaller size than the skeleton-spicules, and of uniform structure, and nearly all of the same size. Mr. Carter has named them rosettes. They differ in the form of their six rays—which are always equal, sometimes simple, ending in a
Dr. J. EK. Gray on the Arrangement of Sponges. 289
crenated disk, and at others are simple, subulate, with a more or less spinulose surface, or each divided at the end into two, three, or more linear branches, which are frequently dilated at the end.
In the paper in the ‘Annals’ above referred to I divided the sponges of this suborder according to their external form ; but in the ‘Ann. & Mag. Nat. Hist.’ 1872, x. p. 184, I pro- posed to divide them into two groups according to the form of the free spicules; and since then Mr. Carter has shown the importance of the study of the minute free spicules, or rosettes.
They may be divided into three sections, as proposed in the ‘Annals,’ 1872, x. p. 134:— .
1. The rosettes with the ends of the six rays divided into two, three, four, five, or many branches. Including Harreadw, Dactylocalycide, Aphrocallistide, Euplectellade, Corbi- tellade, Askonematide, and Crateromorphade (Ann. & Mag. Nat. Hist. 1872, x. p. 134), and Rossella, Carter.
2. The rosettes with six rays ending in a radiating circular disk. Carteriade, Pieronemade, and Meyerinade (Ann. & Mag. Nat. Hist. 1872, x. p. 134).
Mr. Carter figures many of the rosettes of these genera (Ann. & Mag. Nat. Hist. 1873, xii. t. 13 & 15).
3. The rosettes subcubical, the rays with three lobes at the
end. Azide.
I gave the name of Axos Cliftont to Bowerbank’s figure (B. 8. fig. 197) of the spicule of this sponge; and when Mr. Clifton gave me a fragment of the sponge I described it (Ann. & Mag. Nat. Hist. 1870, vi. p. 272) under the name of Hehino- spongia australis; but at p. 346 of the same volume I showed that Azxos Cliftoni should be adopted. Dr. Bowerbank has since figured the specimen from which the fragment was taken by Mr. Clifton under the name of Dictyocylindrus dentatus (Proc. Zool. Soc. 1873, p. 321, t. xxix.), without referring to his figure in his work on British sponges.
Suborder IIT. QUINQUERADIATOSPONGIA.
Sponges with spicules of the quinqueradiate type in com- bination with the simple spicules of Leiospongia, and frequently having multiradiate spicules and spicular spherules in combi- nation with them, either scattered free in the flesh of the sponge or forming an external bark to it.
The sponges of this suborder present very numerous com- binations of spicules ; and the five-rayed spicules which form the skeleton of the sponge frequently want the outer end of
290 = Dr. J. E. Gray on the Arrangement of Sponges.
the shaft, and the lower end is generally much elongated ; and for this reason they have been called four-rayed, trifurcate, or nail-like spicules. They frequently have free, but more or less abundant, regular-shaped many-rayed spicules, or spicular spherules, scattered in their flesk, which are always of a small size, and more or less regular in their shape.
This order consists of the Spherospongia and the family MacAndrewiade of the ‘Annals,’ 1872, ix. p. 456.
Section I. Five-rayed or skeleton-spicules often united by siliceous matter; flesh-spicules fusiform, cylindrical, more or less spinose. Lithistide, Carter (Ann. & Mag. Nat. Hist. 1873, xii. p. 437); MacAndrewiade, Gray (Ann. & Mag. Nat. Hist. 1872, ix. p. 456.
The sponge formed of superficial sexradiate spicules, which are held together by an amorphous siliceous coat.
Mr. Carter gives an arrangement of the species of the various genera of this group, to which the genera Mac- Andrewia and Theonella, Gray, Corallistes and Leiodermttium of Schmidt, and Azorica and Lithospongitis, Carter, are re- ferable. In the ‘Annals’ I placed MacAndrewiade with the Coralloid sponges having sexradiate spicules; but the ex- amination of more spicules has proved that they belong to the quinqueradiate type, with the habit of the coral-sponges.
Section II. The skeleton-spicules elongate, free from one another, generally forming the circumference of the sponge, sometimes projecting beyond it.
a. The free flesh-spicules many-rayed, stellate, on the outer surface or inner part of the sarcode. Tethyade, Dona- tiade, Theneade, Lophurellade,Casulade. (See Ecio- nemia acervus, and H. densa, Bowerbank, Proc. Zool. Soc. 1873, t. xxx. figs. 1-14.)
b. With spicular spherules forming the outer surface of the sponge. Geodiade.
c. The spicular spherules crowded together, and forming the axis and plates on the outer surface of the coral- like sponge, with the sarcode and spicules between the two. Placospongiade.
d. Without any many-rayed stellate spicules or spicular spherules. Ancorinade.
e. Aberrant family, Chondrillade, with many-rayed stellate flesh-spicules, but without any elongate five-rayed spicules. See Chondrilla australiensis, Ann. & Mag.

XXXVIJI.—On a new Species of Arcturus (A. damnoniensis). By the Rev. THomas R. R. Srespine, M.A.
{Plate XV. ]
ARCTURUS DAMNONIENSIS has three conical tubercles on the head—one medio-frontal, with the other two side by side behind it. Hach of the body-segments has a similar elevation—that on the elongated fourth segment, not quite so far back as the centre of its dorsal surface, being the most considerable and conspic- uous. ‘T’o this almost central tubercle the dorsal surface of the segment slopes rather steeply up and then rather steeply down to a second tubercle, truncated at the top and standing over the posterior margin. The tubercles of the other segments are less important in size and more sharply pointed than those of the head and the fourth body-segment, that on the second segment being the most diminutive.
Of the pleon or tail three segments are clearly defined :—the first very short ; the second less so, and dorsally raised above both the first and the last, the long terminal piece having also a small dorsal elevation in close proximity to that of the second segment. The terminal piece has also at the base a lobe on each side running out into a sharp angle. Further back the lateral margin is again produced into a similar angle ; between this and the rather obtuse apex there is a slight in- dentation in the margin on either side, the two being connected by a small dorsal furrow.
The upper antenne are about as long as the head; they have a large basal joint, followed by three slender almost trans- parent articulations and a short seta, the last articulation being longer than the two which precede it both together.
The lower antenne are as long as the body ; four joints are visible and a stiff little-divided flagellum. The first of the four joints is short and thick with a deep external notch; the second is long, clubbed at the distal end; the third is longer again; the fourth is about the same length as the second, but slender and uniform in thickness. All the joints have short outstanding hairs or bristles. The third joint is longer in the male than the female, and in each about corresponds in length with the fourth body-segment. =
The female is altogether more strongly tuberculated than the male; and the lateral dilatations over the insertions of the legs are also more pronounced in the female than in the male. The most striking difference, however, between the two sexes is in the fourth body-segment; for this segment in the female, besides carrying the brood-pouch, is dilated at its origin into a large triangular lobe on either side, while in the male there

is a decided contraction of the body in the front part of the fourth segment. ‘This difference is very noticeable when the two specimens are viewed from above instead of in profile.
The total length of each specimen is about half an inch.
The male it fell to my lot to discover in January of this present year, 1874. It was clinging to a small stalk of sea- weed which had been dredged up in the neighbourhood of Babbacombe beach. The following day the meshes of the dredge, which had been plied off Hope’s Nose, at a distance of a mile or more from the site of our previous search, yielded the female. This time Mr. W. Wilson Saunders, my companion on both occasions, was the successful discoverer. The dredging off Babbacombe had given us nothing of interest besides the Arcturus and Crangon trispinosus; that off Hope’s Nose, in water of more than 10 fathoms depth, supplied many scores of specimens of Antedon rosaceus (Comatula), the feather-star, besides several crustaceans of more or less rarity, both stalk- eyed and gessile-eyed—including of the former Hurynome aspera and Pennant’s Hbalia, and of the latter Ampelisca Gai- mardii, Cerapus abditus, Anthura gracilis, Anceus maxillaris, and Idotea linearis.

stripe and numerous small yellowish ocelli; sides deep brown, with a bright yellowish wavy streak above and below.
The British’ Museum has ‘received this species from ‘T'as- mania. Collected by R. Gunn, Esq.
Mocoa mustelina, n. sp.
Elongate and slender in form ; head small; limbs short and weak. Superficial resemblance to Hinulia ornata in coloration ; but, besides being distinctly a Mocoa, it has much larger and fewer scales: there are 22-24 longitudinal rows as counted round the body, and 52 ina longitudinal ventral series; while in Hinulia ornata these numbers are respectively 30 and 62. Colour: bright yellowish brown above, with small mottlings and wavy lines and variegations along the sides, extending in regular streaks on the tail; lower surface pure white; chin dotted with brown; a pure white oblong spot immediately behind the eye.
The British Museum possesses three specimens from New
South Wales.
Mocoa microlepidota, n. sp.
Body somewhat depressed. Scales small, those on the back distinctly three-ridged. Lower eyelid tr ansparent. Nasals and fronto-nasals not contiguous ; internasal broad, saddle- shaped ; fronto-parictal single: - no supranasals ; 38 longi- tudinal series of scales as counted round the body, 83 in a longitudinal ventral series. Dorsal surface closely speckled with black and olive, a marginal olive stripe along upper edge of sides ; sides with a deep band of dark brown, speckled and breaking into the eneous bluish green of the lower surface, which is also very minutely speckled with brown on the chin. Tail with small uniform scales ; when reproduced, a single very broad series inferiorly.
In the collection of the British Museum, from Van Diemen’s Land. From the Sydney Museum.
Mocoa metallica, n. sp.
Lower eyelid transparent; supranasals none. Scales di- stinetly four- or five-keeled, the projections being well defined but not sharp. Body stout, tetragonal; limbs rather short ; ear-opening large. Nasals and fronto-nasals not contiguous ; frontal short, triang ular, of the same size as or smaller than the single fronto- -parietal, which it joms with its truncated point. Supralabials six, the four anterior subequal, that under the eye more prolonged. Scales in 28 longitudinal series, the

two median dorsal being very broad ; in a longitudinal ventral row there are 60, and these latter are smaller than the dorsal scales. Colours: above bright bronzed green, with a median dark brown stripe and lateral variegations more or less irre- gular; sides dark brown, broken up into irregular variegations ; beneath greenish, dotted on chin.
In the British Museum, from Van Diemen’s Land. Col- lected by R. Gunn, Esq.
In several other specimens (Dr. Millingen’s collection) the ground-colour is much darker, and may be described as greenish brown, the pattern, however, being the same.
Mocoa pseudocarinata, n. sp.
Two small black skinks from Tasmania, also from Mr.Gunn’s collection, present curiously ridged, or rather perhaps in- dented scales, three or four indentations being distinct to- wards the margin of all the scales, both dorsal and ventral. Lower eyelid transparent ; no supranasals. Scales rather con- vex, distinct grooves between the series the whole length of the body. Fronto-parietals united in one specimen, in the other apparently separated by an irregular suture. Shining black above, with two narrow light stripes from head along the upper
5
and lower margins of the sides. Scales in 28 longitudinal
series, and 62 in ventral series.
Mabouya punctatissima, n. sp.
Supranasals narrow, oblique, contiguous ; internasal broad, saddle-shaped; fronto-nasals contiguous, broad; fronto-parietals separate ; supralabials seven, the five anterior subequal, that under the eye longer; ear-opening large. Scales moderate, rounded, smooth, equal all over the body; in 42 longitudinal series, 69 in a longitudinal ventral series. Hind legs not quite as long as the side, fore legs reaching to end of muzzle. ‘Tail somewhat longer than head and body. Colour greenish brown, punctulated all over the upper surface with dark brown and occasional white dots; lower parts pale greenish.
The British Museum possesses one specimen of this form, which was purchased of M. Parzudaki, who gave the Cape of Good Hope as its locality, which we must consider very doubtful.
Euprepes fogoensis, D. & B.
Superficially resembling £. Stangerz, but with much smaller
new Species of Scincide. 301
scales, there being 56-60 longitudinal series, and 100 in a longitudinal ventral series. Scales two-keeled, uniform in size allover the body. Supranasals contiguous ; fronto-nasals contiguous ; fronto-parietals separate; supralabials six; ear- opening moderate, rounded, with small scales anteriorly. Limbs moderate. Tail somewhat longer than head and body. Colour olive-brown ; two series of strie, consisting of minute ocellations of dark brown intersprinkled with whitish, forming almost two long stripes on each side of the back ; sides brown, similarly variegated and mottled; belly pale ; chin and chest variegated with brown.
Cape-Verde Islands. Many specimens, adult and young, from the islands of Fogo and St. Vincent’s in the Cape-Verde group, from the collection of the Rev. R. T. Lowe.
By its two-keeled scales this species is allied to Macro- scincus Coctec; but the teeth are not serrated.
Diploglossus millepunctatus.
Head elongate, flattened, broadening posteriorly ; supra- nasals two pair, large, contiguous; nostrils in nasal shield, above suture between first and second labials, with a curved groove behind them; three large plates between eye and nasal; internasal broad, tapering posteriorly, separating the two long semirhomboidal fronto-nasals.

Scales of body and tail small, rounded, smooth or with strize obso- lete; in about 56 longitudinal series, and 64 in a median dorsal series from shoulder to groin, and 116 scales in a longitudinal ventral series. Colour dark brown, with an infinite number of minute white specks, one, two, or three on every scale. Fore limbs, laid forwards, not reaching tip of snout, hind limbs reaching halfway along sides of body.

Subkingdom MOLLUSC.
Section I. MOLLUSCOIDA. Class I. POLYZOA.
The majority of the Polyzoa come from the deep water of the bay; and, indeed, there are comparatively few to be met with between tide-marks that do not also occur in the former. The minute animals of the calcareous masses so characteristic of many of this group, perform none of those alterations on the surface of the earth which the equally tiny coral-polyps daily effect ; yet their workmanship in our northern waters is as regular and beautiful as that fashioned by the latter in the tropical seas. The patterns of the Lepralie, for instance, excite admiration; and though the apparent resemblance in growth, superficial aspect, and position may suggest to some an analogy between them and the lichens of our rocks and trees, yet it is remote and unable to bear close criti- cism. It is true it is difficult to assign an exact function to these organisms; but in some cases the calcareous crust of the Lepralic affords a better hold to many stationary marine animals than the rock itself. Moreover, after heavy-coated forms (like the Balan?) have reared themselves on this basis, it frequently happens that the original crust is loosened from its attachment, and both fall off together. The coating of Lepralie, also, may prevent to some extent the disintegration of soft rocks and stones. By removing a portion of bark with - an adherent Balanus from a submerged thorn-tree, and care- fully detaching the former, a fine network of Lepralia is found lowest, then the calcareous coating of the Balanus; and if the latter has perished, a rough layer of Cellepora pumicosa obliterates all trace of it from without.
- The Cheilostomatous Polyzoa are fairly represented ; and several, e. g. Flustra and Gemellaria, occur in vast quantities attached to stones, shells, and corallines on the West Sands after storms. ‘The majority are common to the eastern shores, the west, and the extreme north and south, as shown in the valuable catalogues of Messrs. Alder, Couch, Hincks, and Norman. Many species will doubtless yet be found at St.
Molluscoida of St. Andrews. 303
Andrews—though at present they appear to be confined to the other areas, which have been more thoroughly investigated by observers specially skilled in this department. Bicellaria ciliata and Bugula purpurotincta seem to be more common at St. Andrews than in Shetland, the latter form being especially abundant and fine, and apparently taking the place of the BL. plumosa of the southern shores; Menipea ternata and Bugula Murrayana are likewise in considerable profusion and in fine condition; while the southern Flustra chartacea is wholly absent. The species of the Membraniporide, perhaps, are more abundant in Shetland; and the Lepralie are decidedly more numerous there and in the extreme south. Amongst the more conspicuous forms we notice the entire absence of Lepralia Pallasiana, so common in the extreme west and south, and of the characteristic LZ. ernominata and L. figularis of the latter. The Celleporide are abundant, but the species are few. Cellepora avicularis is exceptionally rich, according to Mr. Hincks; and the same high authority in this department states that the sole specimen of Hschara Skene? is fine.
The Cyclostomatous forms are not numerous; but all the examples are abundant; and the same may be said of the Ctenostomata. The late Dr. John Reid mentions Vestcularia spinosa as growing near low-water mark ; but I have not been successful in finding it. The Zetlandic Hornera and the rich tufts of Amathia lendigera, so plentiful in the south, are altogether absent.
On the whole it would appear that the Hebridean, Zetlandic, and southern waters furnish a richer field for the Polyzoa than our eastern shores, not only as regards the number of species, but the condition and size of the specimens. I need only allude, for instance, to the luxuriance of the branching Celleporidee and Retepore of the Hebrides and Shetland, and the extraordinary beauty and profusion of the Escharidz and Lepraliz, and indeed of the whole group, in the extreme south and in the Channel Islands, both between tide-marks and on the shell-banks around.
The arrangement followed is that of Mr. Busk in his accurate and well-known and_ beautifully-illustrated ‘Cata- logue ;’ and I have further derived great assistance from the valuable Catalogue of the Zoophytes of Northumberland and Durham by the lamented Joshua Alder, and the extensive Zetlandic lists by the Rev. A. M. Norman. I have also to thank Mr. Hincks for his kindness in revising the list and making several additions, and to acknowledge the information derived from his careful and original Catalogue of the southern forms.

Class II. TUNICATA.
Comparatively few Ascidians have been procured ; indeed the department is in such a condition at present (as to specific identification) that a much greater amount of time would have been required for their elucidation than was available. The late Mr. Joshua Alder most kindly looked over the collection, and named those requiring identification in his usual con- scientious manner; and it is to be hoped that the work on these forms by him and the late Mr. Hancock (one of the best minute anatomists this country has produced) will soon be published. The most abundant simple form is the Ascédia sordida of Alder and Hancock, which is thrown by storms on the West Sands in large numbers, attached to sea- weeds, sticks, shells, and other objects. A. ¢ntest/nalis is also procured in this manner as well as between tide-marks ; Pelonaia corrugata and Molgula arenosa, A. & H., affect deep water only, and rarely occur during storms. The compound forms are common under stones between tide-marks and in the laminarian region: but much yet remains to be done in this respect at St. Andrews. Though Ascidians on the ex- posed parts of the east coast of Scotland are for the most part rare in the laminarian region and between tide-marks, they are common in still muddy waters on the west coast and in the Hebrides, and in water which cannot but be slightly brackish, as at the head of Loch Portan near Lochmaddy, where they are both abundant and large; they are also numerous and large between tide-marks at Herm and in the rich waters around the Channel Islands, as well as in the Zetlandic voes,

XLII.—On the Spongozoa of Halisarca Dujardinii. By H. J. Carter, F.R.S. &e.
Ty the ‘Annals’ for last year (vol. xii. p. 17) I published a paper on two new species of Gumminee, with special and general observations. I had not then seen Halisarca Dujardinit of our shores, but have since met with it several times, always small, never more than from a quarter to three quarters of an inch in diameter.
I have also stated somewhere lately, with reference to the spongozoa, that what I claim is not to have shown that they were ciliated, but that they took in crude food and threw off the undigested portions like Ameba. This I have now also proved to be the case in Halisarca Dujardinit, in the following manner :—
Yesterday (March 19th) I went to the rocks here (Budleigh- Salterton), and found a specimen of Halisarca Dujardinii, about a quarter of an inch in diameter, on a bit of dead stick about the size of a tobacco-pipe. The stick was cut off to a convenient length and placed in sea-water; and thus, the following morning, it was brought under an inch compound power, when, seeing the particles of refuse matter actively issuing from the vent, I rubbed up a little indigo also in sea- water and, with a camel-hair brush, dropped it on the speci- men, leaving it there about an hour, until I saw particles of the indigo itself issuing from the vent.
The water was then agitated so as to float away the super- incumbent indigo, when it was observed that some of the Hali- sarca had become deeply coloured by it.
Now, taking off a portion of the coloured part, and tearing it to pieces with needles on a slide in sea-water, this was covered with a bit of thin glass, and placed under a 4-inch compound power.
Thus the spongozoa of the Hulisarca were brought into view. Some were isolated, others still remaining in their
316 Dr. J. E. Gray on a New-Zealand Whale.
natural groups. ‘The isolated ones, which contained the indigo, were more or less globular, from 1 to 14 6000th of an inch in diameter; provided with a short, pointed beak supporting a single cilium, about five times the diameter in length, and throwing out and retracting ray-like pseudopodia from their circumference, which was thus ever changing its form.
The “groups” consisted of an aggregation of such spongo- zoa charged with the indigo, and altogether formed round or elliptical dark blue masses, with a hollow interior and a cir- cumference not only fringed with cilia, which were motionless, but also with a number of shorter ray-like pseudopodia.
The interiors appeared to be in direct communication with the branched system of excretory canals; but how the particles of indigo get from the pores to the canals I am ignorant. Possibly the pores and the canals may also be in direet communication, and cilia not only take the particles of food into the spongozoa, but, by reverse action, bring out the undigested parts by the same course.
Thus, however, in Halisarca Dujardinii the same kind of spongozoa exist as probably in all the other sponges, aggre- gated into similar groups, communicating respectively with the excretory system of canals.
I need hardly add that Halisarca Dujardinii is void of spicules, as Dujardin and Johnston have described it (‘Annals,’ loc. eit.), and not the spiculiferous sponge described by Dr. Bowerbank under this name. It is, menus the spicules, of the same structure as the Gumminee ; and therefore all these gelatinous sponges may be assumed to possess the same kind of spongozoa (vide ‘Annals,’ loc. cit.).
XLUI.—On a New-Zealand Whale (Physalus antarcticus, Hutton), with Notes. By Dr. J. E. Gray, F.R.S. &e.
[Plate XVI.]
Pror. F. W. Hutton, keeper of the Otago Museum, Dunedin, New Zealand, has sent the skeleton of a whale taken off Otago Head in October, 1873. He has also sent a slight ac- count accompanied by a drawing of the whale, and the measure- ments of it when fresh, as follows :—

Mr. Hutton has considered this whale to be my Physalus antarcticus, noticed in the ‘ Zoology of the Erebus and Terror,’ from a quantity of yellowish white baleen sold as New- Zealand whalebone. But the small size of the whale, only 16 feet long, and the baleen being described as yellow with a narrow black margin, makes me think it probable that the animal is the one which yields the long slender whalebone on which I established the pigmy whale (Balena marginata), which, we know, inhabits New-Zealand, because Governor Grey found its skull on the island of Kawau; it was figured by Dr. Hector, and was constituted by me a genus, Neobalena (see Ann. & Mag. Nat. Hist. 1870, v. p. 221,-vi. p. 155, figs. 1 & 2).
If this should prove to be the case, it will be a very important discovery ; for it will prove that the genus Neobalena forms a group intermediate between the true whales and the finners (Physalide). The animal, though it has the throat and front part of chest plaited like the finners, has the large head and short body of the whales, the head being one fourth the entire length, and the caudal fin in breadth rather more than one fourth the entire length from end of tail.
It is to be regretted that Mr. Hutton did not describe the shape of the baleen—if it was short and broad like that of the finners, or long and slender like that of the Balenide.
The baleen on which I established Physalus antarcticus is short and broad, like that of a true Physalus, and evidently belonged to a much larger whale than the one from Otago Head.
Neobalena, although it has the whalebone of the true Balenide, has a very peculiar kind of skull and ear-bone ; and I should not be at all astonished to find that it has the plaited
318 Mr. F. Smith on the Genus Epicharis.
throat and dorsal fin of a finner, combined with the short body and large head of a true whale (Balenide). The ear-bone is somewhat intermediate in form between the two groups, and fully justifies my opinion that when the entire animal and skeleton are known it may prove to be the type of a new family of whales (Suppl.

Synopsis of the Acridide of North America. By Cyrus Tomas, Ph.D. Being Part I. of the Fifth Volume of the ‘ Report of the United-States Geological Survey of the Territories, issued by the Department of the Interior. 4to: Washington, 1873.
THERE is one particular in which the Government of the United States puts those of European countries to utter shame. This is the liberality shown in America in the promotion of scientific research, both by the central Government and by the Legislatures of the various States. All over the States geological surveyors are hard at work; and the results of their labours are given to the world in a constantly increasing series of valuable yolumes, which are most liberally circulated gratuitously in other countries. With a breadth of view which deserves all praise, the geological surveyors do not confine themselves to mapping the geological formations of various districts, and describing the fossils obtained from them, but they de- vote a good deal of attention to the recent productions of the regions traversed by them; and the results of their investigations are pub- lished from time to time at the public cost, and as an integral part of the work properly belonging to the surveys.
Dr. Thomas’s “ Synopsis of the Acridide of North America ” is one of these publications, and it forms the first part of a volume which is to be devoted exclusively to the recent zoology and botany of the United States. After giving a list of works on the Ortho- ptera referred to in his monograph, the author describes, in consider- able detail, the external and internal structure of the insects belong- ing to the family the American species of which form its subject- matter. This introduction, which is illustrated with two outline wood-engravings, furnishes a guide to the terminology of the parts in these insects.
With regard to the oviposition of the Acridide, Dr. Thomas states that the destructive migratory species of the West (Caloptenus spretus), like the migratory locusts of Europe, deposits its eggs, to the number of 50 or 100, in a cocoon-like mass, covered with a tough glutinous secretion, but that this method is by no means followed by all other American species. Even the red-legged locust (Caloptenus femur-rubrum) was found by him to lay its eggs loosely in rotten wood.
Bibliographical Notice. 323
Dr. Thomas enters at great length into the question of the clas- sification of the Orthoptera, and gives a complete revision of all the more important systems which have been proposed by various authors, from Linnzus downwards. His final result is an adoption of Burmeister’s classification of the families, except that he includes the Forficulide, placed by Burmeister as a distinct tribe. He divides his Acridide into two subfamilies, the Acridine and the Tettiginee, and the former again into seven groups, as shown in the following Table (p. 40) :—

Mr. Walker’s Pamphagide are included in the group Xiphocerini. Five of the above groups have representatives in the fauna of the United States, the first, third, and seventh being deficient. In the present work, however, Dr. Thomas works out the genera and species only of four groups, the Tettiginze being described chiefly from the writings of previous entomologists.
The author tells us that the number of species of Acrididz (ex- clusive of Tettigine) known to occur in the United States is about 120, belonging to 25 genera. The number described in Fischer’s ‘Orthoptera Europea’ (1853) was 77, belonging to 20 genera. The total number of species (including 20 Tettigine) found in the North-American region (taking in British America, Mexico and Central America, and the West Indies) is 227; these belong to 46 genera, 4 of which are Tettigine. Characters of these, principally compiled from the writings of other authors, are given as a sort of appendix to the body of the ‘‘ Synopsis.’ Of the 120 species in- habiting the United States, 40 have been described as new by the author in this and former memoirs; and he tells us that many of these have been figured by Professor Townend Glover in a lately

published work, entitled ‘Illustrations of North-American Ento- mology,’ which we have not seen.
Of course any special criticism of this work is quite out of the question, unless one were prepared to go through nearly the same amount of labour that the author has bestowed upon it. The genera and species are most carefully characterized, tables are freely intro- duced to facilitate their determination, and the whole book bears the impress of most conscientious work. Here and there we seem to see indications of a desire to draw the line of specific distinction too tightly ; but without a knowledge of the species it is of course impossible to pronounce a decided opinion upon such matters; and we can only welcome Dr. Thomas’s memoir as a most important contribution to our knowledge of American entomology. It 1s illus- trated with a nicely executed plate of outline figures, designed to show the general characters of a few of the genera referred to.

Eozoon canadense. By Prof. Max Scuvtrze.
Tue discovery of the American geologists Sir William Logan and Prof. Dawson with regard to a peculiar fossil in the primeeval lime- stones of the oldest formation of Canada, which they thought must be referred to the Foraminifera, and named Hozoon canadense, has ob- tained a provisional settlement by the investigations of Dr. W. B.Car- penter, of London, whose extensive works upon the Foraminifera are recognized as occupying the first rank. Carpenter considers there is no doubt that the discoidal masses, about a foot in diameter and several inches thick, composed of alternate layers of greenish sili- cates (serpentine or augite) and carbonate of lime (or magnesia), which, caked together into irregular nests, occur in the Laurentian deposits of Canada hitherto regarded as perfectly azoic, represent the remains of a many-chambered Foraminifer of the habit of the Acervuline, M. Schultze. Like the glauconitic filling of more recent Foraminifera, the serpentinous mass of the Hozoon has penetrated into the interior of the chambers, while the intervening calcareous bands represent the original calcareous walls of the chambers. In these, in well-preserved specimens, there is a complex, ramified canal-system, connected with the original cavities of the chambers, and filled, like these, with a silicate which is insoluble in acids. Carpenter compares them to the canals detected in various fossil and recent Foraminifera, which occur arranged in bundles, as, for - example, in Calcarina or Siderolites calcitrapoides from the chalk of Maestricht.
The statements of the above-mentioned. English and American observers have been received with much mistrust, especially in Ger- many. In fact there can be no doubt that much of what has been given out as Hozoon shows no kind of organic structure when ex- amined under sufficiently high powers. The author therefore
Miscellaneous. 320
thought it important to make a fresh examination of admitted ori- ginal specimens. Such a specimen, transmitted directly by Dawson, was placed at his disposal by Professors Schimper and Benecke, on the occasion of his visiting the museum at Strasburg. From his investigation of this specimen and of some received from Carpenter, the author confirmed, and showed in numerous drawings, the pre- sence of a highly developed canal-system in many of the calcareous bands, especially the broader ones. The form and arrangement of these canals is often beautifully preserved, even though their in- terior is filled with a crystalline silicate. Here and there the struc- ture has the greatest resemblance to that of the dentine of the teeth, which is also traversed by canals. But for many reasons there can be no question of dentine in this case. The application of stronger powers shows that in the finer structure of the canals there is so great an agreement with that of Polytrema among the living Acervuline, that, weighing all the other conditions of struc- ture which come into consideration, there can be no serious doubt as to the foraminiferous nature of Hozoon canadense.—From a report of the Meeting of the Niederrheinische Gesellschaft fur Natur- und Heilkunde at Bonn, July 7, 1873, in the ‘Kélner Zeitung,’ August 14, 1873.
Notes on the Skulls of two undescribed Species of Sea-lions (Otaria). By Dr. J. E. Gray, F.R.S. &c.
The British Museum has a series of fourteen skulls of the common sea-lion, from the largest size (16 inches long) to that of the pups, and of both sexes.
They are all characterized by their short, broad lower jaws, the space between the under part of the two sides being bowed out, and the lower margin, from the gonyx to the angle of the jaw, being of the,same length as the space between the two jaws at the angle.
Phe lower jaws are swollen on the sides and broad infront. The scar of the temporal muscle on the hinder part of the lower jaw is broad, rounded in front. There are specimens in the Museum from various parts of South America, as Peru, Chili, the Falkland Islands, and the Coast of Patagonia.
The skulls of the young and of some of the older ones have the sixth upper grinder behind the back edge of the front of the zygo- matic arch; but in the skulls of the aged animals the zygoma is dila- ted, and the tooth comes to be partially or entirely before the hinder edge of the zygoma, sometimes differing on the two sides of the same skull.
In the British Museum there are two skulls of adult animals which differ in having the lower jaws straight, not bowed on the side, and elongate, the lower margin from the angle to the gonyx being cousiderably longer than the space between the two sides of the jaw at the angle, and the front of the lower jaw flattened on the sides, and the scar of the temporal muscle is elongate, narrow in front. I propose to name them

Otaria minor. The Smaller Sea-lion.
Skull of an adult male 113 inches long, and 64 inches wide at the condyles; the nose dilated in front; the palate very deep, wide, broad in front, contracted behind, with the lateral processes rather contracted, the sixth upper grinder behind the edge of the front of the zygomatic arch ; the lower jaw 83 inches long, wide and strong, contracted and flat on the sides in front, and with an elongated scar behind left by the temporal muscle.
Hab. Unknown. Received from Mr. E. Cross, 1854.
This skull may be the same as Otaria Godeffroyi, Peters, described and figured from a specimen in the museum at Hamburg, which is about the same size; but the lower jaw is not of the same shape as the lower jaw of the skull in the Museum, the scar of the large temporal muscle is broad and rounded at the end, as in the jaws of the common sea-lion, and the sixth upper grinder is before the back edge of the front of the zygoma; so that I am inclined to think that the Hamburg skull belongs to a small species allied to, or is a small variety of, the common sea-lion (Otaria jubata).
Otaria pygmea. The Pigmy Sea-lion.
The skull of an adult (female) 9} inches long, and 5} broad at the condyles.
The palate is very narrow, deep, scarcely wider behind; the sixth upper grinder is behind the hinder edge of the front of the zygomatic arch. The lower jaw is comparatively slender, 63 inches long, compressed and flat in front.
Hab. Unknown. The specimen was received from the Zoologi- eal Society in 1858.
This skull is partly broken behind, and wants all the grinders and the greater part of the cutting-teeth. The canines are com- paratively small, which makes me think thatit belongs to a female ; indeed I might regard it as the female belonging to the same species as the skull before described, but for the peculiar form and narrow- ness of the palate.
The palates of the two sexes of the common sea-lion are of the same form, though they become deep with age and those of the males more contracted behind; so that they give no authority for believing that the palates of the two sexes of an allied species are so different.
The Succession of Life in North America. By Epwarp D. Corr,
The United States east of the Missouri river and the plains have been free from changes of level for a much longer period than that portion which lies to the west of such an imaginary line. It was alternately dry and submerged during a long period in the infancy of geological time, but became finally so established as to permit of no further descent of level, or, at most, of slight ones only. The last stages of this process of creation were witnessed at the close of the Carboniferous period, when the elevations of land were wide- spread, inclosing tracts of water within bars or in depressions,
Miscellaneous. ont
These water areas were of course at first salt; but, as they had no communication with the sea and received abundant supplies of pure water from streams and rains, they soon became fresh. They then became the centres of rank vegetation, which either as moss filled them up with its dense growth, or as large trees formed forests on the shores. Later submergences covered all this material with a heavy coating of mud-deposit, which now appears to us in the form of strata of clay and sandstone rock. Thus was produced the coal, which has played so important a part in human progress. So fre- quent were the alternations of level that at one place in Nova Scotia as many as seventy-six beds of coal separate as many strata of other materials, and the whole amount of deposit amounts to fifteen thousand five hundred feet. As the elevating force became more powerful, the amount of dry land increased, until the lifting of the Alleghany Mountains to a height of twenty thousand feet con- cluded the process.
Previous to this time vertebrated animals had been inhabitants of water only, so far as the preserved remains have been discovered ; but now air-breathers were introduced, which, instead of fins, possessed limbs adapted for walking on dry land. These creatures were all salamanders, and related to the frogs, beginning life in the water and passing through a metamorphosis before reaching the perfect state.
The western regions were during this time occupied by a bound- less ocean, whose western limit has not yet been ascertained ; and such it continued for many ages, while the east was bringing forth plant and animal each afterits kind. The strata deposited in the bottom of the western sea covered each other successively, so that it is only the later chapters of the history that are now revealed to us in the exposed beds of the upper formations. But the history of the east was repeated. Its eastern coast-line rose and fell gradually and islands appeared in the far west, heralding the birth of another continent. Slowly the land areas extended, the western growing from islands to a long narrow continent, honeycombed with lagoons and lakes. The great central sea (now Kansas, Dakota, &c.) contracted and finally lost its connexion with the ocean alto- gether. The water areas, however, were for a long period brackish, and brought forth oysters and other shell-fish of dubious proclivities, capable of living in either salt or fresh water, but thriving in a mixture of both. The land was covered with a rich and dense forest vegetation, and the bog-moss again encroached on the lakes; but the forest was in great contrast to that of the carboniferous period. Instead of huge ferns and tree mosses we have the more highly organized and beautiful forms represented by the existing deciduous trees. Oaks, sassafras, magnolia, and poplar shaded a dense under- growth of shrubs, while palms and some other tropical families di- stinguished the general effect from the familiar one of to-day. But the moss performed its old function of coal-maker. Humblest among plants, its existence has been more important in world- building than that of all the lords of the forest. Its masses died,
23*

and new layers of the living plant grew upon them, until the descent of the land and encroachment of waters deposited the stone lid upon their treasury of carbon, not to be unsealed until the long future day of human empire. The alternations of land and water were numerous. At one point on the Union Pacifie railroad a section displays one hundred and seventy-three distinct strata, of which thirty-six are either coal or mingled with vegetable matter, while the others are frequently composed almost exclusively of fresh- and brackish-water shells. The elevation, however, exceeded the de- pressions, the brackish estuaries and lagoons were transformed into freshwater lakes, and at length the noble ranges of the Rocky Mountains bounded the horizon in many directions.
The salt ocean has not only been the dwelling-place of gill- breathing fishes, but also of many forms of air-breathing vertebrates. These were reptiles, and exhibited a great superiority of structure over the air-breathers that peopled the swamps and land of the coal period. When the land and the fresh waters claimed the great west, the sea saurians perished; for their limbs were not fitted for the changed circumstances, Smaller races held the land, and, with a few monsters that never had been ocean-dwellers, represented the swarming reptilian life of the past.
But a new dynasty was to rule the earth; the mammal, with hot blood and active brain, was to use the rich stores of the newer vege- table world ; and life was to be exhibited on a higher platform.
The lakes of the west were gradually dried by the cutting of their discharging streams down to the level of their bottoms. This was of course soonest accomplished in lakes of the greatest elevation— for instance, those within the highest range of the mountain-chains. Others continued for a longer period, and others to a comparatively still more recent date, Their deposits contain a faithful record of the life of the surrounding land, doubtless embracing many species that ranged to the Atlantic ocean. We have thus the means of studying the character of five successive periods, which must be to us a mine of interesting inquiry, and a source of evidence as to the nature of that life and the thoughts of its great Author.
The names of the beds, with the regions where chiefly found, are the following:—(1) The Lignite series or Upper Cretaceous (Mon- tana, Dakota, Wyoming, Colorado); (2) Eocene Lake (Wyoming, West Colorado); (8) Miocene (Nebraska, Oregon, E. Colorado) ; (4) Pliocene (Nebraska, Idaho, Oregon, E. Colorado); (5) Post- pliocene (caves of the east), The quadrupeds begin in full blast in the Eocene; and none whatever are known from beds of the prece- ding or cretaceous agea—a remarkable circumstance, and not easy to account for, especially as it is the case all over the world, so far as known ; yet there were a few of this high division during a period. that preceded the cretaceous. In Wyoming, therefore, we find life first in the form with which it has pleased Divine power to invest ourselves, but in no case presenting any close resemblance to the human species. The predominant styles were those resembling the tapir, the opossum, the bat, the mole, and the squirrel. There were
Miscellaneous. 329
no cloven-footed animals that chew the cud (ruminants), no horses, no elephants, no rhinoceros or hippopotamus, and, it is thought, no true cat- or dog-like flesh-eaters. To take their places were strange creatures that combine the characteristics of these divisions now so widely separated. Thus there were forms between the horse and tapir, between the elephant and tapir, and between the rhinoceros and tapir. There were numerous monkeys which resembled nearly as much the raccoon and the coati. The land carnivora resembled in many ways the seals ; and the division of the opossum and the kangaroo had sundry representatives. A more curious and, to some, unexpected faunal combination, constituting a homogeneous whole, does not exist in any known formation.
In the next period (Miocene) a great addition to the living types of animals took place; so that the contrast between this formation and the Eocene is very great. <A portion of almost any part of the skeleton of a quadruped would thus enable the paleontologist to de- termine the age of the formation from which it had been procured. Thus ruminating animals exist in the greatest profusion, a few horses appear, two species of elephants (mastodon) are known, and there are a great many species of rhinoceros. The peculiar inter- mediate divisions of the Wyoming beds no longer peopled the land ; the strange beings compounded with the tapir have abandoned the earth in favour of more decided types. One or two tapirs hold over, and one of the anomalous monkeys. The snakes and lizards are nearly the same ; but the crocodiles that swarmed during the Eocene have entirely disappeared.
If we examine the character of the representatives of living orders in greater detail, we shall find the phenomenon observed in the structure of the Eocene quadrupeds repeated, but within a nar- rower limit of variation. Thus the modern ruminants may be roughly stated as belonging to the families of the hogs, camels, musk-deer, and oxen. In the Miocene there are neither oxen nor deer, while many species in enormous droves present structure of hog, camel, and deer combined, or camel plus musk and hog. The horses had three toes and were more or less like tapirs ; and some of the rhinoceroses shared similar peculiarities. One strange set of creatures combined characters of tapir and rhinoceros with those of those Eocene beasts that combined the elephant and tapir. The latter have been called Hobasileus, the former Symborodon. The Hobasileus had three pairs of long horns—the first at the snout, the last on the back of the skull ; the feet were like the elephant’s ; and it carried a pair of knife-like tusks. It probably had a short trunk. The Symborodon had feet more like the rhinoceros, but it stood high on the legs like the elephant ; the tusks were reduced to a small size, while one pair of horns stood upon the top of the head. They represented the front pair of the Hobasileus, and either stood on the nose or over the eyes. Their shape differed in the different species: in some they were long and round, in others flat ; in others they were three-sided and turned outward. One species had enormously expanded cheek-bones, and was nearly as large as

an elephant; it has been called Symborodon bucco. The long- horned species was as large as the Indian rhinoceros, and is called Symborodon acer. The species with three-cornered horns is inter- mediate in size.
Besides these larger quadrupeds there were myriads of the small ones, whose evident adaptation for insect- and seed-eating habits indicate the abundance of such supplies. ‘Thus there were moles, mice, squirrels, and not less than seven species of rabbits. Areas exist where the beds of the formation laid bare by the weather are found to be covered with the delicate remains of these animals. They cover the surface in such profusion as to resemble the loose grain on the farmer’s barn-floor in harvest time.
The Pliocene stratum, above the Miocene, is usually present in the regions where the latter occurs, though not invariably. It has a more sandy character, while the older beds are more clayey. The life they disclose is quite distinct from that we have just passed in review, differing from it much in the same way that it differs from that below it, 7. e. the Eocene. In other words, it is still more like the life of the present time, and the curious intermediate or (to speak inaccurately) the mixed divisions have nearly disap- peared. We have now true dogs and weasels, true elephants, and a few true deers and antelopes. The camels are almost like those now living; and while the horses have three toes, the side toes are much reduced, and the teeth are much more nearly like those of living horses. Rhinoceroses still abound; but all their mixed tapi- roid and elephantine kindred have utterly disappeared.
A curious feature in the dentition of the horses and camels of this period has been observed. The temporary or milk-teeth of the horses were very much like the permanent or second series of the horses of the preceding or Miocene formation. The second or permanent teeth differed from them, and resembled exactly in type the temporary or milk-teeth of the living horses. The case of the camels is similar. Like the hogs they possessed a full set of upper teeth in front, which they soon shed, thus taking on one of their true camel characters; but their permanent series all round after this shedding was like that of the milk-dentition of the existing camels and llamas. In the latter animals the number of the perma- nent teeth is less than that of the first series in one part of the mouth, thus producing another type.
In the fifth and last period we observe another marked change in the life. Most of the Mammalia are nearly related to those now living in this and other continents, while a great many forms of the past are lost. The monkeys did not reach into the Pliocene, so far ~ as we know ; now the rhinoceros leaves us. A few remnants only survive of the camels and horses. Oxen first appear either as the giant bison or the southern musk-oxen ; deer of great size exist. The loss is replaced by South-American types, especially gigantic sloths, in great abundance, with droves of tapirs and pecearies. For the first time we have the raccoons and bears, the latter of the same character as those found with the fossil sloths in Buenos Ayres.
Miscellaneous. 331
True cats, like the jaguar and the tiger, roam the forests; and wea- sels and otters inhabit the banks of the streams.
The modern time has come, so far as the patterns of the animals are concerned ; but their habitations are still different from those which their representatives preserve at the present day. But nearly all the post-pliocene quadrupeds belong to different species from those now living.
The present appearance of the mammalian family in North Ame- rica is due to the following changes :—The llamas, sloths, tapirs, and peccaries have all been banished to Mexico and South America ; so also most of the large cats. The horses, mastodons, and ele- phants were extinguished. The deer type seems to have expanded, while one ox (the bison) and an antelope remain. The wild dogs, weasels, &c. number about as many species now as in the past, while the variety of bears seems to have increased; on the other hand only one of the large cats (the puma) remains. That strange crea- ture the opossum still holds his own far away from his Australian kindred. The smaller rodent quadrupeds are almost as much varied as ever. Many of these changes have evidently been wrought by the glacial period. That frozen epoch brought down the arctic life, and either destroyed those forms that could not resist its rigours, or drove them into a more southern climate. The musk- ox then roamed through the southern States; the walrus haunted the coasts of Virginia ; and the reindeer peopled New Jersey. With the return of the milder period these again sought the north.
But a small proportion of the actual number of the species which lived during these successive ages is yet known, and the field offers many returns for exploration. As an illustration of the manner in which opinions respecting the history of life may be corrected by discovery, I cite two examples. The bony gar-fishes have been often pointed to as exhibiting a remarkable break in the times of appearance in geological history. Their latest fossil relatives were known to have existed during the ancient period called the jurassic ; they did not recur until the present, and now only in the fresh waters of North America. This break of at least one third of all geological time has been recently much reduced by the discovery of gars in great abundance in the Miocene and Eocene periods on this continent. The second case is that of the serpents. They were only known for a long time in the Eocene of New Jersey, then in the same epoch of Wyoming, and lately in the Miocene of Colorado.
Until recently no fossil monkeys, bats, or opossums were known to exist in American formations; and the curious intermediate divisions above described as related to elephant, rhinoceros, tapir, hog, camel, horse, monkey, &c. are all recent American discoveries. —The Penn Monthly, Feb. 1874.
On Xenelaphus, Furcifer, and Coassus peruvianus of the Peruvian Alps. By Dr. J. E. Gray, F.R.S. &e. Mr. Whitely has sent to the British Museum the skins and skulls of a male and female Peruvian deer from Ceuchupate, Peru, at an elevation of 11000 feet.
332 Miscellaneous.
The male, which he calls “Oieidos,” is evidently the same animal as I described (from specimens which he had previously collected) as Xenelaphus chilensis (Ann. & Mag. Nat. Hist. 1873, xii. p. 161), and as the male of the young animal which MM. Gay and Gervais had described in the ‘Ann. Sci. Nat.’ 1846, p. 21, and figured with the skull in the Atlas to Gay’s ‘Chili.’ They live in large troops.
Mr. Whitely’s specimen shows that the horns of the animal which I described as Xenelaphus are probably a malformation both in form and surface ; for they were covered with beads, whereas the horns of the specimen just received have a simple, subulate, slightly grooved beam 9 inches long, with a brow-antler of the same form 6 inches long, curved upwards and inwards at the tip.
The colouring of the face and shape of the horns of Mr. Whitely’s specimen agree with the figure of Cervus antisiensis given in the ‘Atlas’ to D’Orbigny’s ‘ Voyage dans l’Amérique méridionale,’ t. xx., published in 1847. The skull of this animal does not seem to have been observed ; but it probably represents the same species as Cervus chilensis of Gay and Gervais.
As the genus Furcifer of Sundevall was established for the Cervus antisiensis of D’Orbigny, and restricted by me to the guemul, it will have the priority and take the place of the genus Xenelaphus, established on an animal that probably has anomalous horns.
MM. Gay and Gervais published the account of Cervus chilensis in 1846; and Gay afterwards figured the skull, which leaves no doubt about the identity of the species. Their specific name will have priority, and the animal will have to be called Furcifer chilensis.
The female specimen, which is named “ Venados,” is much smaller and has a softer fur; they live always in pairs, and never mix with the Oieidos. It has the general colouring of the “Oieidos ” (Furcifer chilensis), but the top of the face is blackish. This speci- men is accompanied by its skull, and is evidently the same species as the skull of a female obtained from Mr. Whitely in 1873 from Peru, which is figured in the ‘ Hand-list of Ruminants,’ t. xxxy. fig. 2, and as the skull of a male with deformed horns, received from the Zoological Society under the name of Cervus antisiensis, and figured in the ‘Hand-list,’ t. xxxv. fig. 1,—both as Furcifer anti- siensis. These skulls differ from Xenelaphus chilensis and Huamela leucotis in having only a small shallow tear-pit, whereas those animals have a large deep one. ,
There is no doubt that the ‘Venados ” of Peru is quite distinct from all the other South-American deer or skulls of deer that we have in the Museum. The skulls agree with those of Coassus in the small size of the tear-pit; but I do not venture to decide to what genus the only male skull that we have with deformed hérns is to be referred, but will denominate it Cervus (Coassus) peruvi- anus, distinguished from all the other species of Coassus by its large size, of which Furcifer antisiensis, Gray (Ann. & Mag. Nat. Hist. 1873, xii. p. 162, Hand-list of Ruminants, t. xxxv. figs. 1 & 2), will be asynonym. It is quite distinct from the Coassus Whitelyi, Gray (Ann. & Mag. Nat. Hist. 1873, xii. p. 163, Hand-list of Ruminants, t. xxxil. fig. 2), also from Peru.

XLV.—On Duncanella, a new Genus of Paleozoic Corals. By H. AtLteyne Nicuoxson, M.D., D.Sc., F.R.S.E., &c., Professor of Natural History in University College, To- ronto.
My friend Mr. U. P. James, of Cincinnati, well known amongst American paleontologists by his ‘ Catalogue of the Lower Silurian Fossils of Ohio,’ has recently placed in my hands several specimens of a curious little coral from the Niagara group of Indiana, which appears to me to form the type of a new genus, and which I propose to call Duncanella, in honour of Professor P. M. Duncan, one of the highest of living authorities on the fossil Actinozoa. The characters of the genus are as follows :—
Corallum simple, conical, free, and non-adherent. Calice deep, circular, very slightly expanded above. Septa included within the calice, apparently in multiples of six, extending to the centre of the theca. A columella wanting, or at any rate non-determinable. Epitheca well developed, with vertical and encircling strize extending to the margin of the calice, but deficient at the base, where it leaves a circular aperture from which the septa protrude in the form of a small cone. No tabulze or dissepiments.
The affinities of Duncanella would appear to be with the Turbinolide; but it cannot be placed under any recorded genus of this family, nor does it even show any decided rela- tionship with any type of the Aporosa. I should have been

disposed to place these corals under the genus Petraia but for two facts. In the first place, the septa appear to be clearly arranged in multiples of six, being twelve at the base and eighteen in number at the calice; whilst, in the second place, there is the anomalous character that the extreme base of the corallum is destitute of an epitheca. The visceral chamber is thus open below as well as above, the inferior aperture being distinctly circumscribed, circular in form, and exposing to view the slightly exsert septa. At first sight I thought this aperture might perhaps be accidental ; but it is present in all the specimens I have examined, with the excep- tion of one large example, in which it appears to have been cicatrized, and is only obscurely and with difficulty recog- nizable. From the cyathophylloid corals Duncanella is

distinguished by not having the septa in multiples of four, and by the total absence of tabule or dissepiments. From Cyathaxonia, lastly, the present genus is distinguished by its want of a columella and septal fossette, the number of the septa, and the characters of the base.
The following is the only species of the genus that has come under my notice :—
Duncanella borealis (Nicholson).
Corallum simple, free, cylindro-conic, from 7 to 10 lines in length, and 2 lines in diameter at the calice. The base is truncated, destitute of an epitheca, and exhibiting a circular opening about half a line in diameter. Within this opening are seen twelve septa which extend from the circumference to the centre, and usually project slightly in the form of a little cone. The rest of the coral is covered with a well-developed epitheca, which exhibits well-marked longitudinal ridges, together with a few shallow annulations of growth, between

which are fine encircling strie. The calice is extremely deep, occupying about one third of the total length of the corallum, ceylindroid, and only slightly expanded towards its margin. Eighteen equally developed septa appear in transverse sec- tions of the ccral immediately below the bottom of the cup; and these meet in the centre of the visceral chamber, appa- rently without the intervention of any columella, though seemingly somewhat elevated centrally. There are no traces of either tabule or dissepiments, and the interseptal loculi appear to extend uninterruptedly from the base to the calice. Towards the margins of the calice the septa appear to become obsolete ; but their free edges are unknown.

[Plate XVI. B. figs. 1-6.]
AFTER a careful examination of the literature of Ceriopora gracilis, Phillips, sp., the only conclusion we can come to is that a polyzoon and a coral have been confused. With the coral we have not at present to do; but to make clear our position, we ‘shall quote the generic and specific descriptions.
“ CeRIOPORA (pars), Goldfuss, 1826; Blainville, 1834 ; D’Orbigny, 1847.
* Colony fixed by the base, from which cylindrical dichoto- mous branches proceed, giving a dendroid aspect. Hach branch is provided with several superposed layers, enveloping each other, the cells being simply round pores on the surface.
“ Goldfuss, in 1826, placed under Ceriopora a multitude of diverse Bryozoa. In 1834 Blainville considerably restricted the characters of the genus, and only placed in it species pro- vided with several layers of superposed cells, whether the colony is branching or bulbous. Now, in accordance with the plan we have adopted with all the Bryozoa, we think the name Ceriopora ought to be reserved more specially for the branching dendroid species, the globular non-dendroid species forming the genus Reptomulticava. Hence it will be necessary to change the names of several of the Certopore admitted in 1847 into our ‘ Prodrome de Paléontologie Stratigraphique ;’

for at that time we had not recognized the differences based on the presence of one or more layers of cells.” —D’OrBIGNY, Paléontologie Frangaise, v. p. 1029 (1850-52).
“ CERIOPORA, nobis. (Alveolite species, Lam.)
“ Polypary stony, sessile or affixed, composed of several concentric layers of cells enveloping each other; cellules tubular or subprismatic, subcontiguous, parallel or divergent.” —Go.pruss, Petrefacta Germanie, p. 32.
At page 244 the polyp-cells of these corals are described as round short tubes which have neither transverse nor vertical lamellz, neither a siphon nor lateral connecting tubules. They sometimes lie parallel and immediately in contact with each other, and press on each other so as to appear obscurely pris- matic; sometimes they diverge. Their apertures are equal in diameter to the tubes, and are seldom constricted or dilated. The polypary enlarges by the concentric superposition of new layers. The branches of this mass are likewise made up of several layers.
Pictet (‘Traité de Paléontologie,’ 1857, iv. p. 154) places Ceriopora under the family Tubuliporides, tribe Foraminés— among those, therefore, which have the cells pierced in the common calcareous mass, and not salient. He considers this genus one which should rather be abolished than restricted. His definition is, “they form colonies composed of equal or nearly equal cells united by their margins, and not prolonged into tubes.” >
“ Certopora, Goldfuss.
“ Polypidom tuberose, composed of numerous thin concentric layers ; pores round, unequally placed.
“This genus was intended by Goldfuss to include several fossil forms now referred to Alveolites, Chrysaora, &c. The above definition is of the genus as now restricted.” —M‘Coy, Paleozoic Fossils, p. 194.
“ Millepora.— Pores very minute, perpendicular to the surface ; cells without lamella.”—Jbid. p. 195.
Phillips places Milepora, along with Fenestella, Glauconome, &ce., among the Polypiaria, along with Favosites and the other true corals.
Morris (‘ Catalogue of British Fossils,’ edit. 1854) puts Ce- riopora, Goldfuss, 1826, in the Bryozoa, and gives C. gracilis and C. interporosa under that generic heading, Millepora being among the Zoophytes.
Amid this confusion it is apparent that Pictet’s suggestion
of Carboniferous Polyzoa. 337
to set aside Certopora has much to commend it; for the con- fusion of Corals and Bryozoa commenced with Goldfuss. His definition, therefore, is not precise enough, though it is obvious that he founded the genus on a coral. M‘Coy’s restricted genus also belongs to the Corals ; while Morris, by his transfer of the name Cerdopora to a Bryozoon, has left the species under consideration without a generic name to which it has a legiti- mate title. This question of nomenclature is one of great difficulty ; as, however, the essential character of the fossil we are about to describe separates it from all other known Carbo- niferous forms, we would suggest Rhabdomeson as the generic name, the axis being central, not lateral as in Allman’s
Rhabdopleura.

Millepora gracilis, Phillips, Pal. Foss.
Ceriopora gracilis, Morris, Catalogue.
The stem is slender, cylindrical, branching, the branches coming off at right angles to the stem and never less than an inch apart, and consists of a hollow axis formed by a thin ealcareous tube, and of a series of cells ranged round the axis, There are 100 cell-apertures in a linear inch; the apertures are oval, with simple outlines, the funnel-shaped depressions at the bottom of which they are placed sloping down from the erests of the dividing ridges. These ridges are tuberculated, a large tubercle, which well-preserved specimens show to be a blunt spine, being placed at the upper and lower angles of each aper- ture. Hence the periphery of a single cell usually presents four such tubercles, while smaller tubercles occur between each larger pair. But the aperture of the cell does not occupy the whole area of the pore-depression ; a thin lamina reduces the orifice, hymen-like, to one fourth of the area of the pit; and this restricted orifice is at the upper end of the depression (Pl. XVI. B. fig. 4). The cells are conical, the inner extremity being in contact with the axis, the cell turning upwards and out- wards so that the plane of its aperture is parallel to the axis, The apex of the curved cone terminates two cells and a half below its orifice. Towards their apices the cells are separated by a very thin common wall, which thickens outwards so that the orifices are separated by a partition whose thickness is one third of the cei of the cell-cavity at its widest part. When the cells have been removed so as to expose the hollow axis, the wall of the latter is seen to be marked by minute round spots, which at first suggested the possibility of a com- munication existing between the cavity of the cell and that of
338 Messrs. Young on a new Genus
the axis. But careful examination has satisfied us that not merely is the cylinder imperforate, but the cones do not even abut on it; they run out alongside of it. Both axis and cells are filled sometimes with amorphous calcareous matter or with clay sediments. In the latter case the casts obtained by dis- solving away the skeleton with acid (fig. 3) show a notch on the lower side of their widest part corresponding to the thin lamina already mentioned, while the mass lying beyond the notch is the mass of sediment that filled up the pit or vestibule already described. ‘There is no trace of septa in the cell or in the axis; there are no tubules putting adjacent cells in com- munication ; and there is no sign of avicularia or other external processes. ‘The spines are solid; but the worn ones show something like a central pit. We have not found the free ends of any of the branches; but the equality of all the cells forbids the supposition that they are multiplied by intercalation. The central tubular axis has a thin wall, which is distinct from that of the cells in contact with it (fig. 6). In fact, the line of separation between these calcareous layers is everywhere recognizable, and is prolonged into the tubercle or spine (fig. 6,c). The bounding ridge and tubercle are, in fact, shared by adjacent cells, and the calcareous matter is deposited in lamine, as shown roughly in figs. 4, 5, & 6, whereas the walls of the cells as far as the oral lamella are homogeneous. We have not ascertained what is the condition of the calcareous matter in these layers, our chief object being to show that a central pit in these, as in other similar structures, neither implies a central canal nor an articulated appendage. ach cell has, in short, its own proper wall. ‘The cells are throughout equal or nearly so—the differences seen in fig. 2 being of very rare occurrence, though when they exist the regularity of the quin- cunx is impaired. But the equality is such as to forbid the idea that the cells are intercalated, an important point in the definition of Certopora.
Assuming the hydroid character of the Graptolites, Rhabdo- pleura is the only polyzoon hitherto known in which a solid axis is found; and in it the cells terminate the nodes of the axis. The form just described rather resembles a sclerobasic coral in having the axis wholly within the circlet of cells. What may be the true affinities of Rhabdomeson, it would be rash on our part to attempt to determine. The novelty of the type has induced us to publish it at once, reserving the generic definition till we complete our investigations into other species referred erroneously to Ceriopora. We should be glad if collec- tors who may possess forms similar to that here figured would lend us specimens for comparison—and would suggest the
of Carboniferous Polyzoa. 339
propriety of a reexamination of Websterta crisioides, Edw. & Haime, the description having some points of resemblance to that of Rhabdomeson.
Distribution.—Rhabdomeson (Certopora) gracile is common in all the limestones and shales which yield Polyzoa through- out the west of Scotland. It ranges from the lower to the upper members of the Carboniferous Limestone. In some of the harder shales specimens occur two or three inches in length; while by washing the soft and weathered shales, numerous well preserved fragments are easily obtained. In some localities it is associated with species ot Certopora, viz. C. interporosa, Phill., C. rhombifera, Phill., and C, similis, Phill. ; while in other localities it is the only species met with. The white limestone of Trearne, near Beith, Ayrshire, has yielded numerous natural sections. The stone splits in most cases parallel with the axis of the stem, and shows the central hollow tube, bare of cells for considerable lengths. The tube in these specimens never shows more than a fine layer of minute crystals of calcite lining its interior. Those from other localities have the tube more or less filled with amorphous calcite or clay, or both, If the identification with Phillips’s species is correct, this species descends to the Pilton group.

340 Mr. J. Blackwall on certain Peculiarities in the
XLVII.—A Concise Notice of Observations on certain Pecu- liarities in the Structure and Functions of the Araneidea. By Joun Buackwa Lt, F.L.8.
Mucu diversity of opinion being entertained by eminent zoo- tomists and physiologists with regard to the structure and function of certain organs common to spiders belonging to several genera, which are situated near the extremity of the inferior surface of the abdomen, immediately before the spin- ning-mammule, I availed myself of recent visits of a friend, Mr. William Statham, to inspect under his excellent binocular microscope the parts in question, carefully prepared for the purpose by himself. When efficiently illuminated and viewed with a magnifying-power of about 125 diameters, they were distinctly perceived to be provided with very numerous and exceedingly delicate spinning-tubes, completely establishing the accuracy of the conclusion at which I had previously arrived by minute investigation, namely that the parts consti- tute an additional or fourth pair of spinners united throughout their entire length*.
The spiders submitted to examination were Ciniflo atroz, C. similis, and Ergatis viridissima. Between the proximate extremities of the fourth pair of spinners in the first two spe- cies there is a distinct septum; but in Hrgatis viridisstma, Mithras paradoxus, and some other small spiders provided with the additional spinners no septum is apparent, the entire area formed by their contiguous extremities being amply sup- plied with spinning-tubes.
The conjoined spinners composing the fourth pair are moy- able, and, when in action, present their extremities to the calamistra, which in passing over them draw out and card the excessively fine filaments proceeding from the spinning-tubes into the two delicate pale blue bands that enter into the com- position of every flocculus in the complex snares of Cintflo atrox, C. similis, and C. ferox.
The small spiders, the proximate extremities of whose addi- tional spinners are without any definite mark of distinction, have the calamistrum (situated upon a ridge on the abdominal side of the upper surface of the metatarsal joint of each poste- _ rior leg) usually composed of a single row of curved movable bristles ; but the calamistrum of the larger species of Cindflo commonly consists of two parallel rows of fine spines.
I may here remark that the calamistra are frequently much

less conspicuous on male than on female spiders, the occasions for their employment being fewer and of minor importance in the former than in the latter sex.
The prevalent opinion, that the very remarkable snare of Mithras paradoxus does not afford any evidence in its con- struction of the action of the fourth pair of spinners and the calamistra with which this spider is provided, is probably erro- neous; for I have reason to believe that the transverse lines attached to the four radii in the snare of this species are formed by the agency of the calamistra in passing over the extremities of its spinners ; and this agency is undoubtedly exercised in forming the external convex covering of its cocoon. A species of Mithras which inhabits the United States of North America evidently employs its fourth pair of spinners and calamistra in the fabrication of its cell.
Now, as I am disposed to attach much importance to the habits and economy of spiders with reference to their system- atic arrangement, the fact that species provided with calamistra are always found to possess the additional spinners, and that these parts constantly cooperate to produce results affecting their economy in a very obvious manner, has not, [ apprehend, had that consideration bestowed upon it by arachnologists to which it appears to be entitled.
The late Mr. Richard Beck communicated to the Microsco- pical Society of London, in the year 1861, some remarks on the formation of the viscid spiral line in the snare of Epeira ,diadema, commonly denominated the garden spider. In this paper, of which I have merely seen an abstract, the following statement occurs :—‘‘ With only a pocket-lens I could distinctly see that the viscid lines, as first drawn from the abdomen, were not dotted. On a careful examination with the microscope, the thread at first appeared only slightly thicker than an un- gummed line ; but after a very short time undulations appeared, and subsequently, at the most regular distances, the viscid matter formed into alternating large and small globules. The whole process is a beautiful illustration of molecular attraction.” Without questioning the accuracy of Mr. Beck’s observa- tions, several difficulties present themselves in connexion with his explanation of this curious subject, that carefully conducted investigation alone can dispel. ‘To some of these difficulties I shall now direct attention.
The fine elastic line on which the viscid globules are distri- buted is consolidated; but it is perplexing even to conjecture how this consolidation is effected, since, according to Mr. Beck, the line is surrounded by a viscid fluid as it is drawn from the
oes Dr. W. C. M‘Intosh on the
abdomen ; the importance, therefore, of ascertaining by close inspection whether the line and the viscid fluid in which it is enveloped proceed from the same spinning-tube or not will be immediately apparent. It is evident, from the materials of which they are composed possessing such widely different pro- perties, that they cannot be produced by the same organ of secretion.
There is a difficulty also in comprehending how a cylindrical body of viscid fluid can be resolved by molecular attraction into a series of large and small globules disposed on the line alternately at minute and most regular distances from one another.
Had Mr. Beck been spared to continue his researches, he might perhaps have been enabled, by his well-known skill as a microscopist and by the advantage he possessed in having superior optical instruments at his command, to throw some light on the obscure phenomena here submitted to the consi- deration of arachnologists, which remain as problems yet waiting a solution.

Section II. MOLLUSCA (PROPER).
The Mollusca are chiefly procured by dredging, examina- tion between tide-marks, or the deep-sea lines of the fisher- men, though certain storms sometimes strew the sands with many species in great profusion. Not a few of the rarer forms are found in the stomachs of fishes, such as the cod, haddock, and flounder. The remarks on the class may be arranged in three divisions, founded on the economical value, peculiar habits, and rarity.
By far the most important species in the first group is the common mussel (Mytilus edulis), which occurs in vast numbers in the form of mussel-‘ beds”’ on muddy flats, chiefly situated on the right bank of the estuary of the river Eden. Attached to stones, sticks, and to each other, these shell-fish luxuriate in abundance of Diatomacez, Infusoria, and other minute forms of animal and vegetable life. From their special value as bait the city derives a considerable annual revenue ; and if the wise protection only lately enforced were supplemented by
Mollusca of St. Andrews. 343
skilful mussel-farming, great increase in revenue might be anticipated. Shell-fish, like other animals in civilized parts, cannot survive constant inroads without special restrictions. Multitudes of the young mollusks, moreover, are found in- crusting the poles for the salmon-nets on the West Sands, and the rocks, stones, and tangle-roots elsewhere ; but they do not attain a large size, apparently from overcrowding and the want of congenial food, which the purer water seems incapable of supplying. ‘This species takes the place of the horse-mussel (““yoags’’) of the Zetlandic fishermen, and the worms of those in the Channel Islands. It is seldom eaten by the natives. The edible cockles, again, abound on the sandy flats near the entrance of the Hden into the sea, and are occasionally sold as food, though of late years their scarcity has rendered their appearance less frequent in the market. Periwinkles and limpets are constantly gathered for similar purposes. The only uses to which some of the other mollusks are applied are in the amateur manufacture of ornaments, such as shell pin- cushions from various univalves and bivalves, bracelets from Nassa incrassata and Trochus cinerartus, after the latter has had its nacreous layer exposed by an acid.
The rock-boring shell-tish are five in number, though only one exercises any great influence on the disintegration of the rocks—viz. Pholas crispata, which often swarms in the shale and sandstone, and takes the place of the Pholas dactylus of the chalk rocks of the south. Lholas candida occurs too rarely to require special mention in this respect; and the same may be said of Saxicava rugosa. The excavations of Patella vul- gata and Chiton fascicularis in sandstone show that no special boring-organ is necessary for this purpose. The latter species sometimes scoops out considerable cavities in sandstone, in which it reposes. The only wood-borer is Xylophaga dorsalis.
In taking, under this head, a general survey of the boring forms, it is found that they belong to at least three invertebrate subkingdoms, viz. the Protozoa, Mollusea, and Annulosa. In the first are boring sponges ; in the second, Bryozoa and various mollusks; in the third, sea-urchins, gephyreans, annelids, and cirripedes.
The sponges appear to bore only into calcareous substances, such as shells and limestone. The Bryozoa perforate shells ; the mollusks proper, limestone, sandstone, aluminous shale, gneiss and other rocks, wood, wax, shells, &c.; the annelids tunnel shells and rocks of various kinds; the sea-urchins cal- careous rocks, gneiss, granite, and other rocks ; the gephyreans and cirripedes shells and limestone. Good opportunities are afforded at St. Andrews for studying the boring-action of the
344 Dr. W. C. M‘Intosh on the
mollusks and annelids. Pholas crispata and Leucodore ciliata are equally abundant, and must exercise as much influence on the disintegration of the sandstone and shale between tide- marks as the boring sponges amongst the shells in deep water ; while Patella, Chiton, Saxicava, and Dodecaceria are also frequent.
The theories which have been promulgated to explain the mode by which these various creatures perforate materials so diverse may be ranged round two great centres, viz. the chemical and the mechanical*, The advocates of the former seem to take for granted that the borings occur chiefly in calcareous substances ; and with propriety, therefore, they make their solvent an acid. It is clear, however, that this agency is unable to account for the abundant perforations in media totally impervious to such action. Moreover no trace of acid is found in many borers; and though present in some, as in Sabella saxicava and Pholas, it is likewise characteristic of other marine animals which do not bore; and it is purely hypothetical at present to bring in the aid of the carbonic dioxide derived from sea-water, for the same reason.
The mechanical theory, again, supposes that the animals perforate by means of shells or gritty particles m the case of mollusks, teeth in the sea-urchins, bristles in the annelids, horny processes in certain cirripedes and gephyreans; but we are left in doubt concerning the extensive and wonderful per- forations of the sponges, those of the Bryozoa, and the rest of the cirripedes. If, however, we regard the ‘ macerating ” theory as a modification of this, certain of the difficulties will be overcome. The grains of wood, however, found in the stomachs of Teredo, are interesting in this respect.
The whole subject of the boring of marine animals, indeed, is much in want of further elucidation ; and it is hard to believe that the same modus operandi exists in all. In conclusion, the theories may be arranged under the following heads (for all the subkingdoms), after Forbes and Hanley and Gwyn Jeffreys :—
I. That in the shell-fish the perforations are made by rotations
of the valves, like augers (Bonanni, Adanson, Born,
J. E. Gray, Dr. Fleming, Osler, Forbes and Hanley,
Cailliaud, Robertson, &c.) ; in the sea-urchins, by the teeth (Cailliaud).
This theory is not supported by an examination of the
perforations of the sponges, Bryozoa, those of the annelids,
* We do not here allude to the boring by jaws or tongue (e. g, in Lim- norta and Trochus).
Mollusca of St. Andrews. 345
gephyreans, and cirripedes, nor by a comparison of the shells and tunnels of the mollusks themselves. The epidermis of the latter in each case would likewise suffer.
II. That the holes are made by rasping effected by siliceous particles on the foot of the mollusk (Hancock), by grains of silex from the exterior (Bryson), by the foot in some way (Dr. Fischer), and by chitine in the cirripedes (Darwin) and gephyreans and the bristles of the annelids.
This explanation is not borne out by the case of the sponges, by that of the Bryozoa, and certain cirripedes ; moreover such siliceous particles are rare in boring mollusks.
III. That the excavations are due to ciliary currents, aided by rasping (Garner). The currents may assist, but seem to be insufficient to account for the borings in any group.
IV. That the perforations are produced by a chemical solvent : Gray, Osler (for Saxtcava), Drummond, Cailliaud, Mantell, Thorent, Reeve, Bouchard-Chantereaux, Spence Bate, Darwin (for Verruca), E. R. Lankester, and Parfitt.
This will not explain the borings in wood, aluminous shale, gneiss, granite, sandstone, and wax. It is interest- ing, however, as my friend Mr. Ray Lankester has spe- cially shown, that shells and calcareous rocks are much affected by burrowing marine animals.
V. That the borings are the result of a secreted solvent and rasping action (Thompson and Necker). It seems improbable that the solvent should vary with the nature of the rocks attacked.
VI. That the perforations are caused by a macerating or simple solvent action of the foot in mollusks (Sellius, Deshayes, and Gwyn Jeffreys).
It is doubtful if this would be supported by the action in the sponges, Bryozoa, annelids, gephyreans, and cirri- pedes. The striz in certain of the tunnels of the shell- fish are also somewhat at variance with this notion.
The most interesting species in regard to rarity are Lima subauriculata and L. Loscombii, which come from deep water, the characteristic Lima hians of our southern and western shores being,absent. A worn valve of Jsocardia cor found on the West Sands is purely accidental. TZellina pusilla and Psammobia tellinella are uncommon at St. Andrews. Amongst univalves, Trichotropis borealis, Plewrotoma Trevelyana,
346 Dr. W. C. M‘Intosh on the
Aplysia punctata, and Philine pruinosa are noteworthy. The smaller univalves, such as Rissow and their allies, are much less numerous in species than on the southern and west- ern shores, the absence of Trochus umbilicatus being especially diagnostic when contrasted with the latter. The Nudibranchs are well represented at all seasons; and the individuals in the majority of the species are numerous. Ommatostrephes and Loligo amongst the cuttles often occur in great profusion on the West Sands after storms.
On the whole the species are northern, and stand in strong contrast to the molluscan fauna of the western shores, where Thracia convexa, Tapes decussatus, Pecten varius, var. nivea, Teredo megotara and T. norvegica, Fissurella, Trochus umbili- catus and T. zizyphinus in the littoral zone, and the abund- ance of 7. magus and 7. tumidus in the laminarian, Phasianella, Akera bullata, Elysia, swarms of large and small Rissow, and the pelagic Janthina torm conspicuous features of the marine fauna, just as the hosts of Bulimus acutus do on the sandy fields of Killipheder and other parts of the extreme west. Still more evident is the contrast with the rich southern species that cluster round the Channel Islands—such as the finely developed pectens, oysters, and Anomie, and the appearance of the former between tide-marks (P. varius), besides Mytilus barbatus (which takes the place of the bearded varieties of our Mytilus modiolus) in obscure crevices in the littoral zone, the frequency of Arca tetragona in fissures of the rocks, Galeomma on the under surface of stones in tide-pools at Herm, the boring Gastrochena in shells, and the abundance of Haliotis, Pandora, Venus verrucosa and V. ovata, Mactra glauca, the Psammobie, and the “angel’s wings” (Zima), which when disturbed flit with their brilliant orange fringes so nimbly in the tide-pools. Amongst univalves, again, the large size and abundance of Chiton discrepans, Fissurella, Emarginula, Murex erinaceus, Aplysia punctata, Eulima polita, Trochus lineatus, Cerithium and Certthiopsis, and the predatory and cunning cuttles (Octopus) between tide-marks are noteworthy ; while in the surrounding water are the rare prizes Triton nodifer, T. cutaceus, Cardium papillosum, Argiope decollata, and other forms which, with the foregoing, are thrown in such profusion on the shell-beach at Herm—e. g. Calyptrea chinensis, Trochus ~ Montacuti, and Murex aciculatus. ‘The fine Pinna rudis of South England is also entirely absent at St. Andrews. Neither dowe find the swarms of Trochus helicinus and T. grenlandicus, Trichotropis borealis, and their allies amongst the tangle- roots, as in Shetland, nor the Terebratulw, Lyonsia, Lepeta, Puncturella, Trochus amabilis, the Jeffreysie, Columbella ha- lieet?, Pleurotoma nivalis, P. carinata, Scaphander librarius,
Mollusca of St. Andrews. 347
Philine angulata and P. nitida, Rossia papillifera, the Clios, and the half hundred new British forms discovered by Mr. Gwyn Jeffreys in his frequent cruises in the surrounding waters. The great beds, also, of Mytilus modiolus (called “‘yoags ”), which occur in from 3 to 15 fathoms near the shore in many parts of the Zetlandic seas, present an interesting contrast. It is this mussel (esteemed but a coarse bait at St. Andrews) which is extensively employed by the Shetlanders ; and in its collection many rare invertebrates are found amongst the roots of the tangles and stones, which with the mussels form huge muddy masses. The old ten-toothed “dreg” noticed by the accomplished Prof. Edward Forbes is still the chief instrument in procuring the shell-fish, and is much more service- able to the zoologist on such ground than the dredge. In the figure given by the facile pencil of the great naturalist the rope is attached to the eye of the dreg; but in modern times the fishermen more correctly attach it to the head of the instru- ment (after the mannerof the ordinary dredge), and fix the rope at the eye of the dreg by a piece of spun yarn; ¢ so that if the dreg gets entangled { the spun yarn gives way, and the rope pulls the head of the dreg back- wards, and disengages the teeth from the tangles and stones. In trans- verse section the teeth form a trun- cated ellipse round the central iron rod.
The nomenclature adopted is that of Mr. Gwyn Jeffreys in his valuable work on the British Mollusca ; and I am specially indebted to him for his great courtesy in frequently aiding me in doubtful cases, and also carefully investigating shell-débris containing minute species, which otherwise might have been overlooked.

L.—Notes on the Small Spotted Eagle of Northern Germany, Aquila maculata (Gm.). By H. E. Dresser, F.Z.S.
For some time I have been carefully working at the most difficult group amongst the eagles, that comprising those usu- ally known by the name of “ Spotted”? Kagles, and have by no means yet been able to elucidate matters to my satisfaction. A day or two ago, however, my friend and late colleague, Mr. R. B. Sharpe, showed me the proof-sheets of a portion of his Museum catalogue, now in the process of publication; and | observed that he therein uses the name of Aquila nevia for the small Pomeranian and North-German Spotted Eagle. Although this species, in common with the larger Spotted Eagle which is found in Europe and Asia, has so long borne this name, I convinced myselt, some months ago, that it cer- tainly does not belong to it, though I am by no means sure to which species Gmelin’s name of nwvia should apply. I have, however, never published any information I have acquired on this subject ; but as Mr. Sharpe, to whom I communicated some portion of it, wishes to refer to my notes in his catalogue, I have arranged with him to publish a short notice, giving the rea- sons why I refuse to accept the title of Aguila nevia for the smaller Spotted Eagle. They are as follows :—J. F. Gmelin, who first referred to an eagle under the name of Falco nevius (Syst. Nat. i. p. 258. no. 49), which has generally been looked on as being the Small Spotted Eagle, bases his description on that of Brisson’s Aigle tacheté (Orn. i. p. 425. no. 4, 1760). Brisson, however, does not describe the bird from a specimen in his own possession, but refers to other authors, some of whose works (as, for instance, the one first mentioned, that of Schwenckfeld) are not to be had for reference. He refers,
374. On the Small Spotted Eagle of Northern Germany.
however, to a plate in Frisch’s ‘ Vogel Deutschlands’ as giving an accurate representation of his “ Aigle tacheté,”’ in the fol- lowing words :—“Buteo. Frisch. hujus icon accurata tab. 71.” I possess a copy of Frisch’s work ; and on reference to the plate I found that the bird there represented is any thing but the Spotted Eagle, and might, I think, except for the partially feathered tarsi, possibly be meant to represent the Golden Eagle, though it does not agree with any stage of plumage of that bird which I have seen. It represents a large blackish brown eagle, regularly though indistinctly marked (so far as can be ascertained), by the centres of the feathers being darker than the outer portions; and the feathering on_ the tarsus only extends down to within about one third of the base of the claws, this latter portion being bare. Frisch, in his letterpress, speaks of it as the Stecn-Adler or Génse- Aar (the former being the German appellation for the Golden Eagle), and says that it is somewhat smaller than the Sea- Eagle. He further states that it has the tarsi only partly feathered, and is blackish brown in colour, like his Aquila melanaétus, which is evidently the young of the Sea-Eagle. He speaks of having kept one for some time in captivity ; and, so far as I can judge, the bird he had was a young Golden Eagle, more especially as he says that it inhabits rocky places and high mountains. _ He further writes that he thinks it may be a buzzard (“ich halte nicht ohne Grund dafiir, es sey dieses der rechte Busaar oder Bushard”’). The above, I think, clearly shows that the bird figured by Frisch, to which Brisson refers as being an accurate representation of his “‘Aigle tacheté,” cannot possibly be the Spotted Eagle.
To return to Brisson, I may point out several reasons why his description cannot possibly refer to the small Spotted Eagle. He gives its total length as being 2 feet 7 inches and 6 lines, or, in our English measure, 33°7 inches, which utterly precludes its being this species, as an old and large female only measures in the skin 25 inches in length. He further speaks of the throat being dirty white, the waderparts of the wings spotted, the underparts of the body generally dull fer- ruginous, the legs covered with dull ferrugimous feathers and spotted with white, and the tail-feathers white at the base and the end, and otherwise dark ferruginous marked with large transverse brown spots, none of which characters agrees with young spotted specimens of this bird which I possess. I must confess that I am utterly unable to discover what species it is to which Brisson refers, but am quite convinced that it is not the small Spotted Eagle, which I hold must bear the name of Aguila maculata (Gm.), ex Lath.
On a new Species of Humming-bird. B75
J. F. Gmelin (Syst. Nat. i. p. 258. no 50) describes this eagle as follows :—‘ Longitudo bipedalis. Rostrum magnum et ungues nigri; irides cinerez ; penn scapularum et tectrices alarum apice macula ovali albicante insignite ; dorsi maculis coloris bubalini; venter similibus lineis striatus,’ which deserip- tion agrees well with a specimen in my collection from Silesia. He further refers to Latham, of whose description (Synopsis, i. p. 38. no. 15, 1781) he has evidently made use in giving the above characters. Latham’s description is most clear, and certainly refers to the small North-German Spotted Eagle ; and the only measurement he gives (the total length), which he says is 2 feet, agrees precisely with specimens of this bird in my possession. He states that his description was taken from a specimen in good condition in the British Museum, but he does not say where it was obtained.
I may add that on showing Mr. Sharpe my reasons for using the name of maculata instead of nevia for the present species, he quite agrees with me in the propriety of so doing.
LI.—Description of an apparently new Species of Humming- bird of the Genus Eriocnemis. By D. G. Exxior, F.L.S., | ups det BM ao
Eriocnemis chrysorama.
Top of head, back, flanks, breast, and abdomen brillant me- tallic fiery red, darkest on the head; chin and throat metallic golden yellow ; upper tail-coverts, extending half the length of tail, metallic yellowish green ; under tail-coverts, basal half white, remainder metallic blue; wings purplish brown; tail much forked, steel-black ; tufts on tarsi large, pure white; bill black ; small spot on base of mandible, next to the chin, yellow, perhaps red in life. Total length 4} inches, wing 23, tail 14, bill 4.
This very brilliant and handsome bird approaches closest to the EZ. mosquera, and resembles it somewhat in the colour of the lower parts, but is more brilliant and fiery. It is, how- ever, smaller in all its measurements except the bill. The throat-mark is very broad, and extends quite down to the breast.
I do not know the habitat of this species ; but the specimen was stated to have come from Ecuador.

LII.—On the Structure called Kozoon canadense in the Lau- rentian Limestone of Canada. By H. J. Carter, F.R.S. &e.
I seg by Dr. Carpenter’s ‘ Remarks” in the last number of the ‘ Annals’ that, in my letter to Prof. King on the so-called ““ Hozoon canadense”’ (‘ Annals,’ March 1874, xii. p. 189), I did not lay sufficient stress on the parallelism of the acicular structure with the grains of serpentine. ‘This is particularly well shown in the illustrations 1, 2,3, 5, 6,9, and 10 of Profs. King and Rowney’s paper in the ‘Transactions of the Royal Trish Academy, vol. x. p. 506, from which I have taken the liberty of causing to be copied fig. 1, pl. 1, which is repro- duced in the following woodcut.
From the “description”? of this figure, I learn that it represents ‘fa portion of a ‘chamber-cast’ from a_ trans- parent section of ‘ eozoonal’ ophite from Canada, presented to Dr. Rowney by Dr. Car- penter, as seen by reflected light with a power magnifying 120 diameters.”
a is the portion of a ‘ chamber-cast,’ ¢ d the acicular struc- ture or so-called “ tubuli,” ‘ nummuline layer,” or “ nummu- line tubulation,” and 6 the serpentine seen through the latter.
Now I can testify to this, as well as to all the other illus- trations of the kind given in this paper, as being correct instances of the parallelism of the acicule with the serpentine.
Hence this character is wtterly incompatible with foramini- feral structure ; for the tubuli of the chambers of the testaceous Foraminifera forming in juxtaposition a crust of columnar tubes which keep up a direct communication between the cavity of the chamber and the outer world, necessarily take the shortest course to produce this ; and that course is therefore perpendicular to the surface or confines of the chamber and not parallel to it—in other words, a “‘ straight line.”
If there be any inclination, it is exceptional and not the rule ; for Nature here, as in all other instances, is ever economic of
her means.
Now what do we find in the so-called ‘‘ eozoonal limestone”’? that the acicular structure, which has been stated to represent the tubuli, is almost always parallel to the serpentine, after the manner shown in the illustration.
Thus, if there be even only one instance where the parallel- tsm can be demonstrated, it would show that the acicule could

not have been the tubuli of a foraminiferal chamber ; while its general occurrence makes the case conclusive.
It is instructive, if not amusing, to compare the facsimile illustrations of the eozoonal limestone given by the Galway mineralogists with the ‘ constructed” figure of the same given by Dr. Carpenter’s artist in the last number of the ‘ Annals ;’ and thus it may be understood why I stated to Dr. Carpenter that I had not read any thing that had been written on the opposite side of the question, or words to this effect (/. c. p. 278).
Beyond this structure it is not necessary to go for conviction. Of course the tubuli may not be seen in the arenaceous Fora- minifera, where sand supplies the place of a calcareous test, but undoubtedly in the larger testaceous Foraminifera, where the test is formed of lime ; and it so happens that to the structure of these I have heretofore chiefly directed my attention.
Before Schultze’s or Carpenter’s books were published, I had deseribed and illustrated, in the ‘ Annals,’ the canal-system, ‘“‘nummuline”’ tubulation, and general structure of the Fora- minifera, both in the recent Operculina and in the fossilized Nummulite (‘ Annals,’ 1852, vol. x. p. 161, pl. iv.). Even Schultze in his book, as well as I can remember (for I have not the work by me to refer to), gives me the credit of having discovered the “ canal-system,” which at least proves the priority of my publications ; and since then up to the present time I have more or less occupied myself with the structure of Foraminifera, as my papers in the ‘ Annals’ will show.
Even during the last four years that I have been engaged in the general and microscopical examination of the British- Museum collection of sponges, for the purpose of bringing them into some kind of order and arrangement in that insti- tution, this study has not been neglected; for, besides a variety of minute Foraminifera which I have found adhermg to these sponges, that have come from various parts of the world, [I have also had ample means of studying on them the beautiful little roseate Polytrema; so that I am able to speak decidedly of the great resemblance which the late Prof. Schultze is re- ported in the last number of the ‘Annals’ to have stated to exist between “ Polytrema and Hozoon canadense.”
As regards the “ canal-system ” in Polytrema, my mounted sections do not show any ; nor do I think it should be expected that a foraminiferous structure merely consisting of cells heaped upon one another with wide intercommunications, finally terminated above in more or less erect branches, each of which presents several large trumpet-shaped openings for the exit of the body-sarcode, should require this ‘“‘ system.”’ However it is stated by Schultze to exist; that is, the “ Re-
378 Mr. H. J. Carter on EKozoon canadense.
port” states that “the application of stronger powers shows that in the finer structure of the canals [of the eozoonal lime- stone ?] there is so great an agreement with that of Polytrema among the living Acervuline, that, weighing all the other con- ditions of structure which come into consideration, there can be no serious doubt as to the foraminiferous nature of Hozoon canadense.”’
What ‘ canals” are here meant in the translated ‘“ Re- port ” it is difficult for me to see—that is, whether they be the ‘‘tubuli’’? or the ‘canal-system.” The term ‘ramified canal-system ’’ is mentioned in the former part of the “ Report,”’ but never the words “ nummuline tubulation”’ or ‘ tubuli.”’ Still, as the position of the latter with respect to the chambers is the sine qué non here, the ‘ ramified canal-system”’ is, so far, of no consequence.
Thus we come to the identification of the tubuli of Polytrema with the aciculz of the eozoonal structure ; and here we have again a repetition of the fact before stated, viz. that in a mounted section of a thin slice of Polytrema wherein the tubuli can be best seen, they are in all places observed to pass directly across the walls of the chambers—that is, to be perpendicular to the surface or confines of the latter ; while in the ‘‘ eozoonal structure ”’ the acicule, which have been stated to be identical with the tubuli, are observed to be parallel or tangential to the grains of serpentine.
That is to say, in the section of eozoonal limestone their ends, for the most part, may be seen around the grains of serpentine, while in the wad/s of the chambers in the section of Polytrema they are always seen to be stdewise.
In short the tubuli of the calcareous foraminiferous test are as perpendicular to the confines of the chambers as the lines of enamel to the dentine of a tooth. Now no one, under any cir- cumstances, could make a section of a tooth in which the lines of the enamel would appear otherwise than perpendicular to the dentine; neither could he do the like with a foraminiferal chamber.
How is it, then, that the “ acicule”’ to which J have alluded are seen endwise (vide woodcut) around and not perpendicular to the confines of the grains of serpentine, if the latter be the cast of a foraminiferous chamber ?
Hither the foraminiferous chambers and their tubuli of the species possessing calcareous tests (for we have nothing to do with arenaceous ones here) belie themselves, which is not likely, or the so-called Hozoon canadense in the Laurentian Limestone is not a fossilized foraminiferous structure.
That Schultze should have failed to realize this is not extra- ordinary under the circumstances.

LIL.—Latest Observations on Kozoon canadense by Prof. Max SCHULTZE.
To the Editors of the Annals and Magazine of Natural History.
2 Hume Street, Dublin.
GENTLEMEN, April 15th, 1874.
I have been requested to allow some extracts from letters received by me from my late much-lamented teacher Professor Max Schultze to be published, as bearing upon a subject which has lately been discussed in the ‘Annals.’ Perhaps if you will kindly publish these few remarks they may serve te throw some Jight upon the /atest views entertained by that great authority on Hozoon canadense.
I have made no observations myself on Hozoon, and am in no way personally interested in the debate which is now going on as regards its true nature. The letters from which I translate extracts, as nearly verbatim as possible, were re- quests to me to procure for Professor Schultze some speci- mens of the stones from Drs. King and Rowney, from the examination of which they had drawn their conclusions as printed in the ‘ Proceedings of the Royal Irish Academy’ for July 1869, which I had sent to him at his request a few days before the date of the letter which I now translate almost in full,
‘Bonn, the 27th Dec. 1873.”
DEAR FRIEND,—I have received Drs. King and Rowney’s paper, and have to thank you most heartily for obtaining it for meso soon. Having read it, you must now let me trouble you again with another request. These gentlemen, with whom I agree on many important points, supported by my own inyes- tigations on J4ozoon canadense, and whose treatise has made a very great impression upon me, would no doubt do me the kind- ness to let me have some specimens of the stones which they characterize as especially important, which it is very difficult for me to procure. It will give you but little trouble to acquaint them with the fact that | am engaged in the study of Hozoon, and am most desirous to obtain some pieces of ‘ Connemara ophites’ and other ophites which I cannot procure in Germany, Perhaps you would undertake this for me, dear friend, and torward me the specimens as soon as possible by ‘ Parcel De- livery ’ or any other way known to you.
Tell Messrs. King and Rowney that, with respect to the ‘proper wall’ of Carpenter, I am entirely of their opimion, that it is of inorganic origin, but would like to push my inyes-
380 Mr. W. C. Hewitson on Butterflies
tigations further as regards the ‘ arborescent canal-system,’ and desire very much, therefore, to have some pieces of Ho- zoon canadense in which the ‘canal-system’ is very distinctly developed. Forgive me if I give you a great deal of trouble ; puis. <2 Me: . ‘“¢ Hoping to be able to return your kindness some time or other, “* Yours in friendship, “MAX SCHULTZE.”
In another letter, dated Dec. 18th, 1873, he regrets not having yet received Drs. King and Rowney’s paper, where- upon I immediately sent it to him; and he acknowledged the receipt of it in the above.
I may state that through the kindness of Dr. King I was enabled to send Professor Schultze some beautiful specimens of the stones he desired, and was expecting from him a letter of acknowledgment when I received the sad news of his death. I have, however, lately written to his widow begging her not to let any of his most recent papers be lost to science, but to have them published, and especially any remarks he may have written on the subject of Hozoon. She has not yet replied.
I have the honour to be, Gentlemen, Yours faithfully, ARTHUR E. BARKER, Surgeon to the City-of-Dublin Hospital
and Demonstrator of Anatomy in Roy. Coll. Surg. Ireland.

of new Species. By W. C. Hewrrson, F.L.S.
FORTUNATELY for natural history as well as for my collection, Lieutenant Bell, to whom I am greatly indebted for butterflies taken under circumstances of so much interest, is a naturalist as well as a soldier ; he most unfortunately, however, became so ill that he had to be sent back in a hammock to the coast and put on board the ‘ Victor Emmanuel’ before he had penetrated further than the Prah. Lieutenant Bell, who is nowin England slowly recovering from fever, speaks of the difficulty of proeu- ring butterflies as great, from the narrowness of the pathways and the density of the bush. Many of them flew only high over head, and never came within his reach.

The rostrum is intermediate in thickness between the general run of the Hyperine and of the Erirhinine ; but in habit it seems more akin to the former.

LVI.—Remarks on the Subject of “ Eozoon.” By Prof. Kine, D.Sc., and Prof. Rowney, D.Ph.
WE have no intention of entering on the discussion opened up by Mr. Carter, F.R.S. &c., in his letter to one of us, and the reply to it by Dr. Carpenter, that have lately appeared in the ‘Annals;’ feeling satisfied that the constructors of tie so-called Eozoon canadense have quite sufficient to attend to in answer- ing the evidences and arguments already brought forward in the papers we have published against its presumed organic origin. Hitherto, and we regret to say it advisedly, no proper attempt has been made to do so.
In our early investigations, and after having fully satisfied ourselves that the various eozoonal structures could not be the remains of an organism, we felt it to be our duty to make an attempt at explaining their mineral origin. They looked much like dendromorphs and acicular crystallizations ; but we soon found that they were not productions of these kinds, nor concretions, nor infiltrations: instead of being incremental, they were obviously decremental. Consisting for the most part of serpentine (an amorphous hydro-silicate of magnesia), this mineral was seen to be affected by an irregular septarian and a subparallel divisional structure, accompanied by some remarkable changes, one fibrous (known to mineralogists as chrysotile), another arborescent (? metaxite), and another floe- culent—all usually of a white colour. Very frequently calcite prevails in the divisional interspaces in association with the latter allomorphs. In such cases the serpentine is broken up into irregularly lobulated or segmented grains, lumps, and plates, separated by the calcitic interspaces ; in which are im- bedded examples of the three allomorphs: the chrysotile is generally an integral portion of the grains and plates of serpen- tine, forming patches of asbestiform coating. ‘The plates of serpentine and their calcitic interspaces occasionally give rise to remarkable interlaminations, while the grains (usually at- tached to one another, but occasionally isolated) occur irregu- larly scattered amongst the calcite. Not unfrequently the serpentine assumes the condition of chrysotile without any cal- cite being present. A close investigation enabled us to see not only the serpentine passing insensibly into compact or true chrysotile and flocculite (as, for the sake of brevity, it may be called), but that the one often became separately acicular, and the other changing from rudely shaped masses into simple and complex arborescences (like those in metaxite), simu- lating, in the most remarkable manner, sponge-structures and dendritic crystallizations. The evidences were so clear and

complete as to prevent our coming to any other conclusion than that they were residual bodies, and not concretions, infil- trations, or crystallizations. As to their being portions of an organism, the idea would not bear any serious considera- tion. Wherever the changes had taken place, a carbacid mineral (calcite, or dolomite) had replaced the chrysotile, flocculite, and metaxite; so that it became evident that we had before us the results of chemical changes analogous to certain kinds of pseudomorphosis occurring among minerals.
Not only does serpentine present unmistakable evidences of the above changes, but certain of them have occurred to us in other silacid minerals, as malacolite and Wollastonite. Agglo- merations of minute crystals of these minerals are common in certain so-called primary limestones (notably at Aker in Sweden, Amity in New York, and in Ceylon), so reduced by solvent or chemical action (the component crystals still retaining in many eases their original angles, edges, and planes) as to assume the exact forms of the “ eozoonal canal-system” in its typical condition, and showing clearly their residual character, also the replacement of their lost or eroded portions by the calcite or dolomite in which they are imbedded.
A more important discovery we had not anticipated. It opens out a wide field of research in chemical geology, an insight into which, however, has been afforded by the illus- trious Bischof. Of late the subject has been frequently under our consideration. It is well known that certain rocks are not in their original chemical condition: the changes in serpentine render it extremely probable that ophite (a silo- earbacid rock) is a chemically changed or methylotic product, that the Tyree, Aker, and other crystalline marbles were ori- ginally silacid masses, and possibly that much of the so-called “‘ limestones ”’ occurring in the Laurentians of Canada were, in Archean periods, silacid members of true gneisses, didrites, and other related rocks*. We need not dwell any longer on this subject; suffice it to say that we are pursuing a number of researches in connexion with it. We have been favoured with specimens by Mr. F. R. Mallet, of the Indian Geological Survey, discovered by himself in dolomitic bands intersecting transversely beds of gneiss at South Mirzapury, showing typi- cal eozoonal structures beautifully developed through methy- lotic action; and last summer one of us obtained at the Lizard, Cornwall, aided by the kindness of Mr. Symons, manager of the Poltesco marble-works, a number of speci-

mens out of apparently a most unpromising rock (serpen- tinite, rarely including any carbacid members), showing its characteristic mineral not only changing as “ eozoon”’ into calcite, but also as a pseudomorph after augite, &c. A de- scription of these cases 1s in preparation for publication.
Our view is that the changes referred to have resulted from the action of heated water holding a carbonate in solution.
But to return to ‘Hozoon.” Dr. Carpenter has kindly offered “to give time and trouble to enable those who wish to make the comparison of actual specimens for themselves.” We would strongly urge on them to take advantage of this offer. We may be permitted, however, to supplement it by suggesting their careful perusal of the memoirs that have been published by us descriptive of similar specimens*, not forgetting those published by Dr. Carpenter and others on his side.
Attention may next be called to the following summary of the arguments and evidences contained in the memoirs re- ferred to :—
1st. The serpentine in ophitic rocks (consisting essentially of serpentine and calcite, with which various other minerals, chiefly silacids and carbacids, are often associated) we have shown to present appearances which can only be explained on the view that it has undergone structural and chemical (me- thylotic) changes :—the former causing it to pass into different subdivided states; and the latter etching out the resulting solids into a variety of forms—grains and plates with lobu- lated or segmented surfaces (“ chamber-casts,” see Dr. Car- penter’s fig. 1), fibres and acicule (‘‘ nummuline chamber- wall”), simple and branching configurations (“ canal-system”), Crystals of malacolite and other silacid minerals (often occurring in ophite and other silo-carbacid rocks) manifest some of these changes in a remarkable degree.
2nd. The “‘intermediate skeleton” of ‘ Hozoon”’ (which often appears as the calcitic matrix of the above lobulated grains&c.T) is completely paralleled in various crystalline rocks, notably marble containing grains of coccolite (Aker and Tyree), pargasite (Finland), chondrodite (New Jersey), &c.
drd. The “chamber-casts” in the granular (acervuline) variety of ‘‘Hozoon”’ are more or less paralleled by the grains of the silacid minerals in the precited marbles.

the Subject of ‘ Kozcon.” 393
4th. The “ chamber-casts ’’ being composed occasionally of Loganite and malacolite (besides serpentine) is a fact which, instead of favouring their organic origin as supposed, must be held as a proof of their having been produced by mineral agencies, inasmuch as the three silacid minerals named have a close pseudomorphic relationship, and may therefore replace one another.
5th. Dr. Giimbel, observing rounded, cylindrical, and tuber- culated grains of coccolite and pargasite in crystalline calci- tic marbles, considered them to be ‘‘ chamber-casts,” or of organic origin. We have shown that such grains often pre- sent crystalline planes, angles, and edges—a fact clearly pro- ving that they were originally aggregations of simple or compound crystals that have undergone external decretion by chemical or solvent action.
6th. We have adduced evidences to show that the ‘‘ num- muline chamber-wall”’* in its typical condition (that is, con- sisting of cylindrical acicule separated by interspaces filled with calcite) has originated directly from closely packed fibres, these from chrysotile or asbestiform serpentine, this from in- cipiently fibrous serpentine, and the latter from the same mineral in its amorphous or structureless condition T.
7th. The “ nummuline wall,” in its typical condition, un- mistakably occurs in cracks or fissures, both in Canadian, Connemara, and other ophites f.
8th. The “‘nummuline wall” is paralleled by the fibrous coat which is occasionally present on the surface of grains of chondrodite§.
9th. We have shown that the relative position of two super-
osed acicular layers (an wpper and an under ‘ nummuline
wall’), and the admitted fact of their component acicule often passing continuously and without interruption from one “ cham- ber-cast’’ to another, to the exclusion of the “ intermediate skeleton,” are totally incompatible with the idea of the said
* Quart, Journ. Geol. Soc. vol. xxii. pl. xiv. figs. 1 & 2; Proceedings Royal Ivish Acad. vol. x. pl. xli. figs. 1 & 2. Few figures of the “cham- ber-wall,” published by the constructors of “Zozoon,’ afford a proper idea of its structure. We were the first to represent it in its typical condition.
+ The so-called “nummuline wall” (asbestiform coat) in Dr. Car- penter’s constructed representation, fig. 2, ought not to be represented in the way it is—bounded by two continuous lines—as it is an integral portion of the grains and plates of serpentine (the so-called ‘chamber casts”’), and not a chemically differentiated part like the true (calcareous) wall of certain Foraminifers.

‘“‘nummuline layers’ having resulted from pseudopodial tubu- lation*.
10th. The so-called “ stolons” and “ passages of communi- cation exactly corresponding with those described in Cyclo- clypeus”’ (fig. 2, 6 6) have been shown to be tabular crystals and variously formed bodies belonging to different silacid minerals, wedged crossways or obliquely in the calcitic inter- spaces between the grains and plates of serpentine.
11th. The “ canal-system ” is composed of serpentine, mala- eolite, and other silacid minerals. Its typical kinds in serpen- tine may be traced in all stages of formation out of plates, prisms, and other solids undergoing a process of superficial decretion {. In malacolite &c. they are made up of crystals (single or aggregated together) that have had their planes, angles, and edges rounded off, or have become further reduced by some solvent.
12th. The ‘“canal-system,” in its remarkable branching varieties, is completely paralleled by crystalline configura- tions in the coccolite marble of Aker, in Sweden, in the cre- vices of a crystal of spinel imbedded in a calcitic matrix from Amity, New York, and in a gemmiferous calcitic rock oecur- ring in Ceylon§.
13th. The configurations, presumed to represent the “ canal- system,” are totally without any regularity 1m their form, rela- tive size, or arrangement; and they occur independently of, and apart from, other “ eozoonal features” (Amity, Boden, &c.),—facts not only demonstrating them to be purely mineral

t Proc. Roy. Irish Acad. vol. x. pl. xliil. figs. 7 & 8, pp. 527 & 528. Speaking of the “ arborescent structure” of the “ canal-system,” Dr. Carpenter assumes that we “ maintain it to consist of mere mineral infil- trations”! And hence, by adopting the following mode of reasoning, he evidently feels that a decisive case has been made out against us. As the “ ramifications pass across the planes of cleavage, every mineralogist will at once say that this is perfectly conclusive—against their being, by any probability, mere inorganic infiltration; that nothing but organic structures could in this manner produce a ramification of one mineral in the interior of another, a ramification of serpentine in the interior of car- bonate of lime passing against its crystalline planes” (‘ Pharmaceutical Journal,’ Feb. 11, 1871, p. 649). If this were the case, it would necessa- rily follow that imbedded minerals which produce “ ramifications ” in the “interior of calcite and passing against its crystalline planes ” (as is com- mon with native silver, prismatic pyrites, glauconite arborescences in calcite or the so-called Hislopite, the latter as made known by Mr. Carter) can be “nothing but organic structures”! It is to be regretted that Dr. Carpenter still makes use of this argument in his last communication.

products, but which strike at the root of the idea that they are of organic origin.
14th. In answer to the argument that, as all the “ eozoonal features’ are occasionally found together in ophite, the com- bination must be considered a conclusive evidence of their organic origin, we have shown, from the composition, phy- sical characters, and circumstances of occurrence and asso- ciation of their component serpentine, that they represent the structural and chemical changes which are eminently and peculiarly characteristic of this mineral*. It has also been shown that the combination is parallel to a remarkable extent in chondrodite and its calcitic matrix fF.
15th. The “regular alternation of lamelle of calcareous and siliceous minerals ’’ (respectively representing the “ interme- diate skeleton’ and “ chamber-casts ’’) occasionally seen in ophite, and considered to be a “ fundamental fact ’’ evidencing an organic arrangement, is proved to be a mineralogical phe- nomenon by the fact that a similar alternation occurs in amphiboline-calcitic marbles and gneissose rocks f.
16th. In order to account for certain untoward difficulties presented by the configurations forming the “ canal-system”’ and the acicule of the ‘‘nummuline layer ’’—that is, when oc- eurring as ‘ solid bundles,’ or when they are ‘ closely packed,” or “appear to be glued together,’—Dr. Carpenter has proposed the theory that the sarcodic extensions which they are presumed to represent have been “ turned into stone”’ (a ‘siliceous mine- ral”’) “ by Nature’s cunning”’ (“just as the sarcodic layer on the surface of the shell of living Foraminifers is formed by the spreading out of coalesced bundles of the pseudopodia that have emerged from the chamber-wall ”)—“ by a process of chemical substitution before their destruction by ordinary decomposi- tion’’§. We showed this quasi-alchymical theory to be alto- gether unscientific ||.
17th. The “siliceous mineral”’ (serpentine) has been ana- logued with those (generalized as glauconite) forming the variously produced casts of recent and fossil Foraminifers. We have shown that the mineral silicates of ‘‘Hozoon”’ have no relation whatever to the substances composing such casts.

Loganite, and malacolite being the presumed in-filling sub- stances of ‘‘Hozoon,” has propounded the “novel doctrine”’ that such minerals were directly deposited in the ocean-waters in which this “ fossil’ lived. We have gone over all his evi- dences and arguments without finding one to be substantiated.
19th. Having investigated the alleged cases of “ cham- bers” and “ tubes”’ occurring “ filled with calcite,” and pre- sumed to be ‘fa conclusive answer to’’ our “ objections,” we have shown that there are the strongest grounds for remo- ving them from the category of reliable evidences on the side of the organic doctrine*. ‘The Tudor specimen has been shown to be equally unavailable.
20th. The occurrence of the best-preserved specimens of * Kozoon canadense”’ in rocks that are in a “ highly crystalline condition ’’ (Dawson) must be accepted as a fact utterly fatal to its organic origin T.
21st. The occurrence of “eozoonal features”’ solely in crystalline or metamorphosed rocks belonging to the Lauren- tian, the Lower Silurian, and the Liassic systems{ (never in ordinary unaltered deposits of these and the intermediate systems) must be assumed as completely demonstrating their purely mineral origin.
It is understood that a communication from Mr. Arthur Barker will appear, showing that, whatever opinion the late Professor Schultze might hold in the autumn of last year respecting ‘‘Hozoon,” he subsequently changed it after reading our papers. Ashe expressed a wish to become fully acquainted with the ‘ canal system,” we were careful in sending him some instructive specimens exhibiting it in various stages of forma- tion.

Mellard Reade, F.G.S., that “ EKozoon” only occurs in metamorphosed rocks (‘ Nature,’ No. 60), asserts that its “calcareous lamelle”’ (‘intermediate skeleton’) ‘show less departure from the shelly texture than do the great majority of undoubted shells, corals, &c. contained in the least- altered rocks of any geological period” (‘ Nature,’ No. 62)—forgetting that as the substance of such fossils has undergone so much change, the fact demands a vast amount of metamorphism to convert the rocks containing them (“least altered” as they may be) into the “highly crystalline condition” of ‘‘eozoonal” ophite. But Dr. Carpenter seems to misunderstand the objection altogether, as it is not based so much on the mineral structure of the “ eozoonal features ” as on the fact that they occur best preserved in “ highly crystalline ” or metamorphosed rocks.

Notice of new Equine Mammals from the Tertiary Formation. By Professor O. C. Marsu.
Iy this paper Prof. Marsh describes a very interesting series of remains of equine animals from the Tertiary deposits of the Western Territories, the fruit of the explorations of a party sent out by Yale College.
The American Eocene mammals of this group belong to a genus lately established by Prof. Marsh under the name of Orohippus ; it is nearly allied to Anchitherium, but differs by “having four functional digits in the manus” and by the absence of the ante- orbital fossa. The dentition is very like that of Anchitheriwm, and its formula is as follows :—
Incisors 3, canines +, premolars +, molars 3.
There is a long diastema; and the canine is large. The known species are Orohippus gracilis, Marsh, O. pumilus, Marsh, O. agilis, Marsh, and O. major, sp. n., all from the Eocene of Wyoming and Utah. 0. major was about the size of a fox.
A form intermediate between Orohippus and Anchitherium is described as constituting a new genus under the name of Miohippus annectens. It has no anteorbital fossa; but there are only three digits in the manus. The dental formula is the same as that of Orohippus ; and the intermediate lobes of the upper molars are more completely separated than in Anchitherium. Miohippus annectens is from the Miocene of Oregon. It was rather larger than a sheep.
Anchitherium anceps and A. celer are two new species. The former, about as large as a sheep, is from the Miocene of Oregon ; the latter, a small species, about two thirds the size of A. Batrdi, is from the Miocene of Nebraska.
Equus parvulus, Marsh (Sill. Journ. xlvi. p. 374), is now referred by the author to Protohippus, Leidy. It is from the Pliocene deposits of Nebraska; and its remains indicate an animal about 23 feet in height. Another species, Protohippus avus, sp. n., from the Pliocene of Oregon, is represented only by teeth; but these indicate such differences from the dentition of other species that the animal will probably prove to be generically distinct.
Pliohippus is a new genus allied to Hquus and having only splint bones in place of the lateral hoofs, but closely resembling Protohippus in its dentition, and possessing a large anteorbital fossa. Its dental formula is as follows :—
Incisors #, canines 1, premolars 4, molars 4.
Pliohippus pernix, sp. n., of which a considerable part of the skeleton has been exhumed from the Pliocene sands of the Niobrara river, Nebraska, was about the size of an ass. A second, and apparently somewhat larger species, P. robustus, sp. n., Was obtained from the same locality.

chippus, A. brevidens, were obtained from Pliocene deposits in Oregon. Prof. Marsh thinks that Leidy’s genera Anchippus and Hyohippus will probably prove to be identical.
Prof. Marsh concludes his paper with the following general remarks :—
The large number of equine mammals now known from the Tertiary deposits of this country, and their regular distribution through the subdivisions of this formation, afford a good oppor- tunity to ascertain the probable lineal descent of the modern horse. The American representative of the latter is the extinct Hquus fraternus, Leidy, a species almost, if not entirely, identical with the Old-World Equus caballus, Linn., to which our recent horse belongs. Huxley has traced successfully the later genealogy of the horse through European extinct forms* ; but the line in America was probably a more direct one, and the record is more complete. Taking, then, as the extremes of a series, Orohippus agilis, Marsh, from the Eocene, and Equus fraternus, Leidy, from the Quaternary, intermediate forms may be intercalated with considerable certainty from the thirty or more well-marked species that lived in the intervening periods. The natural line of descent would seem to be through the following genera :—Orohippus of the Eocene; Miohippus and Anchitheriwm of the Miocene; <Anchippus, Hip- parion, Protohippus, and Pliohippus of the Pliocene; and Equus, Quaternary and recent.
The most marked changes undergone by the successive equine genera are as follows:—Lst, increase in size; 2nd, increase in speed, through concentration of limb-bones; 3rd, elongation of head and neck, and modifications of skull. The increase in size is remarkable. The Eocene Orohippus was about the size of a fox; Miohippus and Anchitherium, from the Miocene, were about as large as a sheep; Hipparion and Pliohippus, of the Pliocene, equalled the ass in height; while the size of the Quaternary Hquus was fully up to that of the modern horse.
The increase of speed was equally marked, and was a direct result of the gradual modification of the limbs. The latter were slowly concentrated, by the reduction of their lateral elements and enlargement of the axial one, until the force exerted by each limb came to act directly through its axis, in the line of motion. This concentration is well seen ¢. g. in the fore limb. There was, Ist, a change in the scapula and humerus, especially in the latter, which facilitated motion in one line only; 2nd, an expansion of the radius and reduction of the ulna, until the former alone remained entire and effective; 3rd, a shortening of all the carpal bones and en- largement of the median ones, ensuring a firmer wrist; 4th, an increase in size of the third digit, at the expense of those on each side, until the former alone supported the limb. The latter change is clearly shown in the following diagram, which represents the fore feet of four typical genera in the equine series, taken in

succession from each of the geological periods in which this group of mammals is known to have lived :—
a
a. Orohippus (Kocene) ; 6. Miohippus (Miocene); ce. Hipparion (Pliocene) ; d, Equus (Quaternary).
The ancient Orohippus had all four digits of the manus well developed. In Miohippus, of the next period, the fifth toe has disappeared, or is only represented by a rudiment, and the limb is supported by the second, third, and fourth, the middle one being the largest. Hipparion, of the later Tertiary, still has three digits ; but the third is much stouter, and the outer ones have ceased to be of use, as they do not touch the ground. In Equus, the last of the series, the lateral hoofs are gone, and the digits themselves are represented only by the rudimentary splint bones*. The middle, or third, digit supports the limb; and its size has increased accord- ingly. The corresponding changes in the posterior limb of these genera are very similar, but not so manifest, as the oldest type (Orohippus) had but three toes behind. An earlier ancestor of the group, perhaps in the lowest Eocene, probably had four toes on this foot, and five in front. Such a predecessor is as clearly indicated by the feet of Orohippus, as the latter is by its Miocene relative. A still older ancestor, possibly in the Cretaceous, doubtless had five toes in each foot, the typical number in mammals. This reduction in the number of toes may perhaps have been due to elevation of the region inhabited, which gradually led the animals to live on higher grounds, instead of the soft lowlands where a polydactyle foot would be an advantage.
The gradual elongation of the head and neck, which took place in the successive genera of this group during the Tertiary period, was a less fundamental change than that which resulted in the reduction of the limbs. The process may be said to have already begun in Orohippus, if we compare that form with other most nearly allied mammals. The diastema, or “place for the bit,” was well developed in both jaws even then, but increased materially

in succeeding genera. The number of the teeth remained the same until the Pliocene, when the front lower premolar was lost; and subsequently the corresponding upper tooth ceased to be functionally developed. The next upper premolar, which in Orohippus was the smallest of the six posterior teeth, rapidly increased in size, and soon became, as in the horse, the largest of the series. The grinding-teeth at first had very short crowns, without cement, and were inserted by distinct roots. In Pliocene species the molars became longer, and were more or less coated with cement. The modern horse has extremely long grinders, without true roots, and covered with a thick external layer of cement. The canine teeth were very large in Orohippus, and in this genus, as well as those from the Middle Tertiary, appear to have been well developed in both sexes. In later forms these teeth declined in size, especially as the changes in the limbs afforded other facilities for defence or escape from danger. The incisors in the early forms were small, and without the character- istic pit of the modern horse. In the genera from the American Eocene and Miocene the orbit was not enclosed behind by an entire bridge of bone; and this first makes its appearance in this country in Pliocene forms. ‘The depression in front of the orbit so characteristic of Anchitherium and some of the Pliocene genera is, strange to say, not seen in Orohippus or the later Miohippus, and is wanting, likewise, in existing horses. It is an interesting fact that the peculiarly equine features acquired by Orohippus are retained persistently throughout the entire series of succeeding forms. Such, ¢. g., is the form of the symphysial part of the lower jaw, and also the characteristic astragalus, with its narrow, oblique, superior ridges, and its small articular facet for the cuboid.
Such is, in brief, a general outline of the more marked changes that seem to have produced in America the highly specialized modern Aguus from his diminutive, four-toed predecessor, the Eocene Orohippus. ‘The line of descent appears to have been direct; and the remains now known supply every important inter- mediate form. It is, of course, impossible to say with certainty through which of the three-toed genera of the Pliocene that lived together the succession came. It is not impossible that the later species, which appear generically identical, are the descendants of more distinct Pliocene types, as the persistent tendency in all the earlier forms was in the same direction. Considering the remarkable development of the group throughout the entire Tertiary period, and its existence even later, it seems very strange that none
of the species should have survived, and that we are indebted for - our present horse to the Old World,

The young Asiatic Tapir (Rhinochcerus sumatranus), By Dr. J. E. Gray, F.R.S. &e.
The British Museum has had for many years a specimen of a young
Miscellaneous. 401
Kuda (2thinocherus), received from Leyden under the name of Tapirus malayanus ; and the Museum has recently received the skin of a much younger animal, which was brought to this country with the skin of an adult animal which is in the Museum. They are both said to have come from Sumatra.
These two young skins differ considerably in the markings; and as I have lately observed the same thing in the American tapirs and figured them (P. Z. 8. 1872, p. 489, t. xxi. & xxii. and p. 624, t. xlv.), I have thought it desirable to describe the two specimens to draw attention to the differences, so as to learn if the young animals vary in this respect or indicate two species distinguished by the different colouring of the young.
Both specimens agree with the young West-Indian and the Peru- vian tapirs in haying their legs and feet with large, white, unequal- sized spots.
The larger specimen received from Leyden is more or less bleached to a brown colour. The back and sides are marked with elongate white spots placed in lines; but the spots frequently do not meet— the ends being above or below the spots behind them, and often pro- duced beyond them. Above and below the upper lateral stripe there is also a series of very small white elongated spots on the hinder part of one side ; and on the other side there are some small spots in a similar place near the shoulder. The two streaks placed on the middle of the sides of the body are broader and more continu- ous than the other spots ; thus on one side the upper one is continuous from the shoulder to over the rump, whereas on the other side it is broken in several places. The series of spots on the middle of the back and sides of the belly are broken into numerous elongate spots of unequal length. The fore and hind legs and feet are marked with rings of roundish white spots.
The younger specimen just received very much agrees with the larger one received from Holland, but is of a blacker colour, being fresh ; and it has nearly the same white streaks, but is destitute of the small spots between the streaks on the hinder parts of the sides. They both have the upper part of the headdestitute of spots, and the lower part, including the cheeks and throat, with a number of similar-sized round white spots.
I am inclined to believe that the spotting or stripes of the young Sumatran tapir is liable to variation, because I observe that, although they have a similar character, their distribution varies considerably on the two sides of the same specimen.
The Habitat of Pelargopsis gigantea. By Dr. Avot Bernnarp Meyer.
On page 123 of the present volume of the ‘Annals’ the habitat of Pelargopsis gigantea is stated as “ Salok, Sulu Islands.” It must be ‘Sulu, Sulu Islands,” if the name be written after the German manner; and the neighbourhood of the town of Sulu is meant, on the island of Sulu, of the group of the Sulu Islands. The Spaniards always pronounce and write “Tol6,” the Dutch chiefly “Sdlog” or
402 Miscellaneous.
« Sdlok,” the English “‘Sooloo,” sometimes “Sulo” &e., the Germans chiefly “Sulu;” and the name has been written in still half a dozen other ways. As the natives on the spot say ‘“Sdlog,” with a soft “s,” it may perhaps be recommended to write the word in this manner.

Contributions towards the Natural History of the Termites. By Dr. Frirz MULLER.
In 1856 C. Lespés discovered that both the soldiers and the workers of Termes lucifugus of the Landes were represented by male and female individuals with incompletely developed sexual organs. This statement was received with some hesitation by certain naturalists, and especially by Hagen, who sought in vain for these organs in the soldiers of various species of Termes and Hodotermes. M. Fritz Miiller’s observations have dispelled the apparent contradictions which rendered this question obscure, and they reveal to us new facts of the highest interest in the history of the Termites.
At first M. Fritz Miiller was no more fortunate than Hagen in dissecting workers or soldiers belonging to several different groups of the genus Termes proper. But in the workers and soldiers of the genus Calotermes he found the organization indicated by Lespés ; and he even ascertained that in the soldiers of this group the repro- ductive organs are much less atrophied than in those of Termes lucifugus, and they acquire nearly the same development as in the winged individuals.
In the soldiers of Calotermes canelle scarcely any external sexual differences are to be found; the ventral plates of the abdomen in the male and female soldiers are constructed as in the winged males. The reproductive organs of the female soldiers are scarcely distin- guishable from those of the winged females, except by their slightly smaller size and the absence of the seminal receptacle. The con- tents of the tubes present some differences when compared with what is seen in the females. The reproductive organs of the male soldiers are exactly like those of the winged males, the testes alone being a little more slender in form.
In Calotermes nodulosus and rugosus, Hagen, the male are at once distinguished from the female soldiers by the structure of the eighth ventral arch. In the small number of female soldiers of CO. nodulosus that he has dissected, the author did not find well characterized ova filling the whole calibre of the ovarian tubes; but he saw them in nearly all the female soldiers of C. rugosus.
As regards the organization of the workers of Calotermes, M. Miller can say nothing, for the very sufficient reason that in the five or six species of that genus which he has observed in Brazil there are no workers at all.
Two forms of nymph had often been observed in the colonies of Termites ; but Lespés was the first to study and describe them care- fully in Termes lucifugus. His “nymphs of the first form,” larger than the workers and larve, are recognizable particularly by their
Miscellaneous. 403
large, thick wing-sheaths, marked with lines representing veins ; in these the female organs are well developed, the male organs very slightly. Lespés saw these nymphs change into perfect insects from the 15th to the 20th May. The “nymphs of the second form,” less numerous than the preceding, become larger, owing to the con- siderable increase of the abdomen. In these the male and female organs acquire an enormous volume. Lespés supposed that these nymphs change in August into winged males and females; but he had made no direct observations upon this point.
* M. F. Miller has been led to form a different conception of the functions of these different nymphs. According to him, male and female reproductive individuals exist under two different forms ; some, originating from the “nymphs of the first form,” acquire wings and quit the nest, a small number of them surviving and becoming kings and queens: the others, which correspond to the “nymphs of the second form,” are destined never to see the light ; they remain apterous, and neyer quit the nest where they were born. The correctness of this hypothesis, which was put forward some time ago, has been proved by this clever naturalist by direct obser- vation. In examining the central part of the nest of a Hutermes, he found it surrounded by a mass of eggs, and ascertained that it did not contain a great royal chamber, but was formed by a sponge- like combination of irregular passages. In these passages were col- lected, in little groups, thirty-one females with short wing-sheaths, from 6 to 8 millims. in length, in the midst of which a male, of nearly the same size, was walking about. This male was a true king, with large eyes; his wings had been detached, leaving only their basal portions. ‘“ Instead of a palace containing a king, living chastely with a mate of his own condition,” says the author, “I had before me a harem in which a sultan was throned in the midst of numerous mistresses.”
These females, whose abdomens were agitated by undulatory con- tractions, like those observed in the queens, laid a great number of eggs in the course of a day; and M. Miler several times witnessed the act of oviposition.
The complemental females (Hrsatzweibchen), as M. Miiller calls them, resemble the workers in their general appearance, but they are twice as large. Their rudimentary wings are so small as not to be perceived in most of them at the first glance. In a small number of individuals these organs acquire larger dimensions, coinciding with a greater development of the mesothorax and metathorax ; they then attain the middle of the second dorsal arch of the abdomen. The head closely resembles that of the workers; as in the latter, the antenne are of fourteen joints, whilst the soldiers have thirteen and the winged individuals fifteen. The only difference between the head in these females and in the workers consists in the presence of small rounded eyes, which scarcely project. The abdomen is only moderately inflated. Each ovary, composed of about a dozen ovarian tubes, contains about six mature ova. Fifteen complemen- tal females together did not weigh more than a single queen; the
404 Miscellaneous.
ovaries of the thirty-one females were not more than equal in weight to those of a queen, and contained scarcely as many ova.
Many questions still remain to be solved with regard to the com- plemental males, the nature of the descendants produced by the different forms of sexual individuals, the causes which induce the development of one or other of these forms, &. Numerous obser- vations and researches will be necessary to enable us to understand thoroughly the working of these complicated societies. Neverthe- less one point seems to be gained, namely the knowledge of the different forms which may be met with in a colony of Termites. M. Fritz Miiller gives the following table of them :—

The author has made numerous observations on the structure of the nests of Termites, and gives a great number of figures which are indispensable for the proper comprehension of these construc- tions. We must content ourselves with mentioning the curious fact that the excrements of the Termites seem to be the materials most employed by these insects, or at least by those which burrow into trees and construct nests in the form of excrescences. If a fragment of the nest be removed, the workers come one after the other to the breach and repair it by depositing their excrements, to which certain individuals add small fragments of the broken wall. Sometimes, also, those which have nothing in the rectum disgorge the food which they have not yet digested. This latter method, probably, is not employed in time of peace; the insects, no doubt, only have recourse to it when it is necessary to repair quickly a
nest broken open by some enemy.
Termes Lespesii, F. Miller, which builds upon the ground, does not exclusively employ its excrements, although these constitute the greater part of the material of the nest; its constructions con- sist partly of a clayey earth. The two substances usually form suc- cessive layers, which vary in thickness and arrangement in different parts of the nest.—Jenaische Zeitschrift, vol. vil. (1873) pp. 333— 358 & 451-463 ; abstract in Bibl. Univ., Arch. des Sci. Phys. et Nat., March 15, 1874, pp. 254-259.

Carcinus menas, Pennant.
Mr. Wood Mason exhibited a specimen of Carcinus menas, Pennant, taken in 1866 or 1867 at Point de Galle, Ceylon, by Dr. J. Anderson. Comparison of this specimen with those from the Mediterranean lately received from Prof. Cornalia, of Milan, had en- abled him to be sure of the correctness of his previous identification from the published figures and descriptions. The species appeared to have an exceedingly wide distribution, being found in abundance on the shores of the British Isles and of the United States, whence it extends to the Arctic Sea, and on all the Mediterranean coasts ; it has also been recorded by Heller from Rio Janeiro; and specimens will doubtless ultimately be met with in the Red Sea.—Proceedings of the Asiatic Society of Bengal, November 1873.
Cetacea of the North Sea and the Baltic.
Professor Malm, in his ‘ Zoological Observations,’ gives a compara- tive account of fifteen specimens of the common porpoise (Phocena Linnei) occurring in the Baltic. He describes and figures a gravid female, and young, and mentions the peculiarities of each specimen. He observes that the small tubercles on the front edge of the dorsal fin, on which Dr. Gray has established Phocena tuberculifera, occur very rarely among these animals ; he only found it in one specimen (no. 13) out of the whole of the male and female specimens which he examined; and therefore he thinks this species is still doubtful.
Professor Mébius gives an account of a male and female grey grampus (Grampus griseus), which were taken on the 17th and 19th of February 1871 on the west coast of Holstein, between the Elbe and Eider. I believe this is the first time that this southern species, which sometimes visits the south coast of England, has been recorded as found so far north.

On some Extinct Types of Horned Perissodactyles. By Epwarp D. Corr, of Philadelphia, Penn.
It is well known that the type of Mammalia of the present period, which is preeminently characterized by the presence of osseous horns, is that of the Artiodactyla Ruminantia. At the meeting of the As- sociation of last year, held at Dubuque, I announced that the horned mammals of our Eocene period were most nearly allied to the Pro- boscidians. I now wish to record the fact (as I believe, for the first time) that the Perissodactyles of the intermediate formation of the

Miocene embraced several genera and species of horned giants not very unlike the Hobasileus and Uintatherium in their armature.
While exploring, in connexion with the United States Geolo- gical Survey of the Territories, I discovered a deposit of the remains of numerous individuals of the above character, which included, among other portions, crania in a good state of preservation. Most of these skulls are nearly or quite 3 feet in length, and mostly deprived of their mandibular portions ; these are quite abundant in a separated condition. The crania represent at least six species, while the mandible represents a condition distinct from that of 7%- tanotherium or any allied genus, viz. 1. 0, C.1, P.M. 3, M. 3. The teeth diminish rapidly in size anteriorly ; and there is no dia- stema behind the canines, whose conic crowns do not exceed those of the premolars in length. To the genus and species thus charac- terized I have elsewhere given the name of Symborodon torvus.
One of the crania, referred to under the name of Miobasileus ophryas, is characterized by its strong and convex nasal bones and concave superior outline posteriorly, and by the presence of a massive horn-core on each side of the front, whose outer face is con- tinuous with the inner wall of the orbit, as in the Loawolophodon cornutus. Itstood above the eye in life, and diverged from its fellow so as to overhang it. In the specimen which was fully adult they were worn obtuse by use—length about 8 inches, thickness 3 inches. The molar teeth differ from those of T%tanotherium Proutii in having cross crests extending inward from the apices of the outer chevrons, each of which dilates into a T-shape near the cones.
The third species is referred to the new genus Symborodon, under the name of S. acer. It has overhanging eyebrows and the vertex little concave ; but the nasal bones are greatly strengthened, and support on each side near the apex a large curved horn-core 10 inches in length with sharply compressed apex. These horns diverge with an outward and backward curve, and when covered with their sheaths must have considerably exceeded a foot in length. This was a truly formidable monster, considerably exceeding the Indian rhinoceros in size.
The fourth species is allied to the last, and has well developed superciliary crests without horns. The latter are situated well anteriorly, and are short tubercles not more than 3 inches in height. They are directed outward, and have a truncate extremity. The type individual is of rather larger size than those of the other species. There are several crania referable to the three now named. The present one has been named Symborodon helocerus.
Other species, based upon crania without mandibles, were referred to the genus Symborodon.
These animals show true characters of the Perissodactyla in their deeply excavated palate, solid odontoid process, third trochanter of femur (which has also a pit for the round ligament), the divided superior ginglymus of the astragalus, &e.—Read before the American Association for the Advancement of Science, Portland Meeting, August 20, 1873.

On new Parasitic Crustacea from the N.W. Coast of America. By W. H. Dart, U.S. Coast Survey.
More than a year ago I submitted to the Academy descriptions of three new species of Cyami from as many species of Pacific Cetacea. On examination of a small collection of parasites in the collec- tion of the Academy (presented by Captain C. M. Scammon, and reported to have been procured from a Pacific right whale near the island of Kadiak, Alaska, in 1873), I find that it contains two species, both apparently undescribed. It is to be presumed that each species of whale has parasites peculiar to itself; and those who have the opportunity of collecting these interesting animals should lose no opportunity of examining the rarer Cetacea, and should pre- serve the parasites of each species carefully by themselves. As there are many species from which no parasites have yet been collected, there are doubtless as many kinds of Cyami which are still un- known.
The species described on pp. 281-283, vol. iv. of the Academy’s ‘ Proceedings’ (‘ Annals,’ 1873, vol. xi. pp. 157, 158), have been well figured on plate x. of Captain Scammon’s ‘ Marine Mammals of the N.W. Coast of America;’ and, in default of a figure of the present species, I have preferred to give a comparative diagnosis by which they may be more readily distinguished from the figured and other described species.
Cyamus tentator, n. sp.
Species in size and general form resembling C. Scammoni, Dall (Scammon, Joc. cit. pl. x. fig. 2), of a pale waxy yellow, with the tips of the branchiw purplish. It differs from C. Scammoni in the fol- lowing particulars:—Head proportionally smaller, not constricted behind the eyes, terminating in a point in the median line behind, which point overlaps a median channel in the body-segment. Second pair of antenne proportionally much longer, equalling twice the length of the head. Second pair of hands with two sharp spike-like tubercles in place of the two rather short and blunt tubercles of C. Scammoni; hands otherwise very similar. Second segment witha broad channel in the median line, widening backward from the head and rather shallow; third segment not rounded at its outer ends, but furnished with very prominent knobs at the anterior and posterior corners on each side ; the outer edges of the fourth seg- ment are also knobbed before and behind, but the anterior knobs are less prominent. The branchie are not spirally twisted, but are straight, laterally extended cylinders, nearly as long as the width of the segment to which they are attached. There are two pairs on each side of the third and fourth segments in the male. The upper pair on each side are not of equal length, as in C. Scammonz, but the inferior branchia of this pair is much shorter than the other ; both are straight or slightly curved upward and forward. The lower pair exist only in the males ; they are very slender and filiform, and quite short ; in the female they seem to be changed into pouches for the

development of the ova. Posterior part of the body as in C. Scam- moni, but there are no serrations on the anterior edge of the seventh segment. Length of largest specimen 0-8 inch.
Domicile on Balena Sieboldii, Gray ; North Pacifie Ocean.
This is readily distinguished from C. mysticeti, Dall, by its spiked “hands” and knobby branchial segments, and from OC. Scammoni by its straight unequal branchie, long antenne, knobs, and the shape of the head.
Cyamus gracilis, n. sp.
This species is of a pale waxen yellow, of elongated and slender form, and small and slender limbs. It more nearly resembles C. suffusus, Dall (Scammon, loc. cit. pl. x. fig. 3), than any of the other described species. It differs from that species in the following par- ticulars :—It is smaller, the largest specimen measuring only 0°5 of an inch in length. It wants the purple colour, and is more compact and solid. The second pair of antenne are much shorter, being only equal to the first segment and half of the next segment of the cor- responding members in C. suffusus. The branchiz, though similar, are proportionally one third shorter. The posterior limbs are shorter and much more weak and slender than in C. suffusus. The first pair of “hands” are slenderly pyriform instead of quadrate ; the second pair are simple, without the tubercles between the articulation of the limb and the “ finger ;” or, at most, in the largest specimens the termination of the hand under the articulation of the hook or finger is slightly produced into a point. The head is shorter, subtriangular, instead of elongated. Lastly the segments of the body are more or less closely appressed against each other before and be- hind, instead of being laterally attenuated and separated as in C. suffusus ; they are also proportionally less wide from side to side than in C. suffusus.
Habitat, with the last.
The prominent features of this species are its slender and compact form, short antennee, and weak and inconspicuous posterior limbs.
Captain T. W. Williams brought down from the Arctic Ocean in 1873 some parasites from the walrus, which he presented to the Academy. ‘These parasites are of a very dark brown colour, almost perfectly round in shape, with an indistinctly segmented abdomen somewhat roughened with short hairs, three pairs of short bristly
legs, a distinct but small throat, and very small and short head. -
There is one pair of short stout antennee with four joints; the mouth is suctorial, There are no other appendages to the abdomen or head. The want of books of reference prevents my being able to refer these creatures to their proper generic position ; andit would be, in any case, unadvisable to describe them as new, as parasites from the walrus of the North Sea have recently been described by a Swedish naturalist, and they may be identical with the present form.—Pro- ceedings of the California Academy of Sciences, March 3, 1874.

LVII.—On a Land-Nemertean found in the Bermudas. By R. v. WILLEMOES-SuuM, Ph.D., Naturalist to the ‘Chal- lenger’ Expedition.
[Plate XVII.}
DuRInG our stay in the Bermudas I frequently visited the mangrove-swamps in Hungry Bay, Bermuda Island, in order to observe and collect the land-crabs. I then also turned over the stones which are scattered on drier land, where the cedar trees begin to dry, and looked out for worms. Lumbricus was very common there; but in the moist earth in which I found them I soon also observed long slimy animals, which were evidently not annelids : having brought them on board, I found them to be Nemerteans. I then returned to the spot and col- lected a good many more of them, which I kept in a bottle with moist earth, and was then able to observe at leisure during our cruise to the Azores.
The largest of these worms have a length of 35 millims. by 2 millims. in width. They are of a milky white colour. Their movements are slow, and sometimes caterpillar-like; they shoot out their long proboscis, fix it at some distant point, to which it adheres by means of its papillae, and draw their body after them. Their skin is filled with rod-like bodies, as de- scribed by Max Schultze and others, and is covered on the outside all over with cilia. In the front we find two pairs of eyes, one of them near the entrance of the proboscis, the other smaller one further out; they consist of a fine granulated pigment imbedded in a colourless substance, which holds these

granules together, in which, however, a regular lens could not be observed. Underneath these eyes is seen the prominent centre of the nervous system (Pl. XVII. fig. 1, 7): it consists of two lobes, and a ring which connects them and encircles the proboscis. From these lobes depart the two lateral nerves (fig. 1,2), and some other cephalic nerves, which were not quite clearly visible. In most genera of the Tremacephalide the cephalic fissures or ciliated sacs are easily to be seen; here they are either very small or wanting entirely. Sometimes a folding of the skin seemed to indicate their presence; but in the contractile bodies of these worms it is very difficult to say whether you have a small cephalic fissure or a folding of the skin before you.
Underneath the ganglion, on the under surface is the semi- circular opening of the mouth (fig. 1,0), leading into an in- testinal tube (fig. 1,7), which runs through the whole length of the animal without showing any thing particular, and is terminated by an anus (fig. 1,a). It is covered above by a long proboscis (fig. 1, pr’—pr*), which opens at the front and ends in the posterior part of the body, where its thin termina- tion is attached to its walls. This proboscis is divided into two portions—the papilligerous part, and the glandular part. At the bottom of the former we find a peculiar spine, the top of which is supposed to be renewed from the smaller spines which are in store in two vesicles on each side of it. This spine is remarkable, because it differs in form according to the sex of its owner. In the male it has a rounded base and is pear-shaped (fig. 2, pr*), while in the female the base has sharpened angles (fig. 3, pr*). Ido not think that such sexual differences have hitherto been observed in Nemerteans.
The ovaries and testes are, as usual, situated between the intestine and the walls of the body. They did not present any thing peculiar, and are not represented in the diagram- matic figure [ have often referred to. Probably the animal is viviparous, as is Tetrastemma obscurum from the Baltic ; but on this subject nothing has been observed.
Though I have not been able to demonstrate the cephalic sacs, which are peculiar to most of the Tremacephalide hitherto described, I think there can be hardly any doubt that this worm belongs to that family ; for some marine species of the genus Tetrastemma bear a most close resemblance to it. I therefore think I can safely call it by this latter generic name, and establish for it the specific name of agricola, as there is probably no described marine species of Tetrastemma with which it could be identified.
I, however, do not attach much importance to this point, as
Land-Nemertean from the Bermudas. 411
the object of these lines is only to show that in America also land-Nemerteans exist. Hitherto they were only known from the Pelew Islands, where Semper has found another Trema- cephalid, to which he has given the name of Geonemertes peleensis. I think it is highly probable that land-Nemerteans exist to a greater extent in tropical countries than has hitherto been supposed, and that, from their hidden life and the im- possibility of preserving them, they have hitherto escaped the attention of travelling naturalists. Especially in such islands as the Bermudas, where the earth of the lower grounds contains a great deal of salt, it may easily be imagined how marine animals have taken to terrestrial habits; and it was interesting for me to see that our Tetrastemma when put into salt water would live there for twenty-four hours, but when put into fresh water died after a few hours time. Fresh water, however, poured over the earth which contained them did not damage them in the least.
I may here also add that on our cruise from the Bermudas to the Azores I found parasitical Nemerteans on Nautilograpsus minutus, one of the gulf-weed crabs. They were small brownish animals, and occupied especially the underside of the crab, under the abdomen of which I found most of them. They did not exceed the length of 2 millims. ; and in none of them could I see genital organs. In fig. 4 I have figured one of these small parasites, which probably also belong to the genus Tetrastemma, though the second pair of eyes is only puncti- form, situated on both sides of the proboscis. Nervous system and digestive apparatus do not present any thing particular ; the proboscis (fig. 4, pr’—pr*) is remarkable for its shortness.
I do not think that these worms attain their full size on the crab ; but believe them to be young parasitical stages of some Nemertean which possibly lives on the gulf-weed. In this group of worms no case of parasitism has, as far as I know, been mentioned before.

Allied to Melanterius ; but differs in its short stout rostrum, absence of ocular lobes, and short second segment of the abdo- men. There is also an evident affinity between this genus and Diethusa, Enide, and Lybeba—genera referred by me to the Krirhinine, from their apparent connexion with Grerynassa, Erytenna, &c. ; but I think now that they will be better placed in the neighbourhood of Melantertus.

In outline like P. tnnominatus (ante, vol. xi. p. 197), but proportionally broader, the prothorax strongly and angularly expanded at the sides, the rostrum stout, comparatively short, and roughly punctured, and the two basal joints of the funicle of nearly equal size, the second perhaps a trifle longer. The fascicles on the elytra are disposed nearly as in P. snnominatus, but are less distinctly limited.
ScOLYPHRUS.
Rostrum subrobustum, arcuatum; scrobes submediane, oblique, ampliate. Scapus in medio rostri insertus; funiculus 7-articu- latus, articulis duobus basalibus longioribus, ultimo in clavam continuato. Prothorax ad latera compressus, supra parum con- vexus, apice productus. Zlytraampla. Femora parum incrassata, mutica; tbie recte ; tarsi lineares, infra haud spongiosi. Abdo- men segmentis duobus basalibus peramplis.
Differentiated from Poropterus by its narrow tarsi, the third joint not being bilobed, canaliculate beneath, with the edges fringed with silky hairs. Agenopus, also having linear tarsi, has the three intermediate segments of the abdomen equal or nearly so. The species described below is a rough-looking insect, with a deep prothorax, the sides below the line of the back compressed and nearly vertical.

The elytra are longer and somewhat differently formed than in P. cordipennis, having coarsely impressed punctures, and with a marked callosity on each side at the base. The femora have two and the tibize one well-defined whitish ring on each of them respectively.
Drassicus infaustus.
D. sat late ovatus, niger, opacus, squamis concoloribus rude vestitus ; rostro rugoso-punctato ; antennis ferrugineis, apicem versus in- fuscatis; scapo brevi, pone medium rostri inserto; funiculo articulis duobus basalibus longitudine equalibus ; prothorace subtransyerso, apice paulo producto, pone apicem vix constricto, in medio utrinque rotundato, modice confertim punctato ; elytris subgloboso-cordatis, basi prothorace haud latioribus, sulcato- punctatis, interstitiis convexis, indistincte griseo-maculatis ; femoribus infra mediocriter dentatis; tibiis brevibus. Long. 23 lin.
Hab. Queensland (Wide Bay).
In the two normal species of Drassicus the apex of the pro- thorax forms a sort of hood over the head; in the above it is of the ordinary character; but although this and some minor points leave a sort of gap between them, there seems nothing of structural importance to show that they are not congeneric.
Imaliodes scrofa.

Differs from the normal forms in its longer rostrum, the pectoral canal terminating a little more between the inter- mediate cox, the club not closely connected to the funicle, and the legs less robust. In habit they are much alike.

Long. 23 lin.
Hab. Rockhampton.
The species here referred to Acalles appear to me to differ in no respect generically from such of the European species as I have examined. They are all dark brown or black, with few scales; and these, arising singly from punctures, are fre- quently more or less erect and claviform or spatulate—common characters among the Cryptorhynchine. The rostrum is com- paratively stout, as a rule perhaps a little shorter than the prothorax, and always very perceptibly broader towards the apex ; the first two abdominal segments are large and pitted with very coarse punctures, each bearing a broad flat, or some- times a narrow curved, scale. Curculio stupidus, Fab. (Ent. Syst. i. p. 432), from the type in the British Museum, appears to be referable to Acalles ; but its tibiee are much longer than usual, and its posterior femora are toothed beneath; in other respects it is like A. bisignatus, but considerably larger. Curculio luridus, Fab. (Ent. Syst. 11. p. 431), placed in Acalles in the Munich Catalogue, is a Poropterus. <Acalles obesus, Boisd. (Astrol. i. p. 438, Tylodes), is probably not Australian : Boisduval gives no habitat; but I have it from Gagie and Ceram, where it was found by Mr. Wallace.
The following table will give an idea of the diagnostic characters of the species here described :—

This species has a prothorax without any trace of the con- striction behind the apex which is a character of most of the species of this extensive genus.
Evororis. Ab Acalle differt tibcvis extus prope basin dente angulato instructis.
This character of the tibiz is seen also in Hmpleurus and one or two other allied genera. It is perhaps of no great im- portance ; but in a large genus like Acalles it is very desirable not to admit any species having a structural peculiarity at variance with its normal forms. The type of the genus is in habit like some of the preceding ; but the sculpture is some- what different :—small deep punctures on the prothorax, each filled with a white scale not rising above the surrounding level; and on the elytra fine punctured strie, with flat, broad interstices, having only very fine traces of punctures.

Abdomen segmentis duobus basalibus ampliatis.
A singular genus belonging to the Tylodes group, but, like its neighbours Plagiocorynus and Glochinorhinus, with no obvious allies. The upper surface of the narrow wedge-shaped elytra is slightly concave and bounded at the side, except towards the apex, by a very strong carina, from which the epipleura descends almost vertically; that it is not quite ver- tical is owing to a marked concavity below the carina; the epipleura itself constitutes the largest part of each elytron.
Ithough this style is common among the Tenebrionide, I do not recollect any other instance of it among the Curculionide, except, to a certain extent, in Hybomorphus and a few others.

Mr. H. J. Carter on Halisarca lobularis. 433
LX.—On Halisarea lobularis, Schmidt, off the South Coast of Devon, with Observations on the Relationship of the SPONGES to the ASCIDIANS, and Hints for Microscopy. By H. J. CarTER, F.R.S. &e.
REFERRING to my account of Halisarca Dujardinii given in the number of the ‘ Annals’ for April, 1874, p. 315, I (taking advantage of the low tide on the 17th April) again visited the “rocks” here, for the purpose, if possible, of finding out the habitat of this sponge, and, when the tide was at its lowest ebb, observed it plentifully on short bits of Chondrus crispus and other small flat-fronded seaweeds of the same kind. But it may grow here and there on almost any and every thing, even to the bare rock itself, although, to the best of my know- ledge, never anywhere where it is likely to be uncovered long by the sea-water.
Tn his ‘ Adriatic Sponges’ of 1862, p. 80, Schmidt states, with reference to what Johnston said in England of this sponge, and Lieberkiihn in Heligoland, that it was “‘ white” (weiss). But if we are to take as “ white” sponges Grantia nivea and the like, which look like so much snow, then the term “white” is not applicable to Halisarca Dujardinit.
Dujardin, who found it on the coast of Normandy and first described it, uses the term “ blanchatre;” Johnston, who found it on the coast of Northumberland, called it “ straw- or ochre-yellow-coloured, mottled ;” and Lieberkiihn, who studied it in Heligoland, uses the words “ weisslich grau;”’ while my own observations in this respect accord with those of Johnston, to which it might be added that when transferred to spirit and water, it becomes opaque and more yellow from the coagulating power of the alcohol over the translucent albumen of which the sponge is chiefly composed.
While engaged in looking after the habitat of Halisarca Dujardinii, I observed a pinkish lobulated substance growing on the rock amongst as well as over other sponges, and, having knocked off the bit of rock on which it was growing, without much injuring the sponge itself, put the whole into sea-water immediately, and thus took it home; where on closer examination I found it to be a specimen of Schmidt’s Hali- sarca lobularis, of the Adriatic Sea, hitherto, I think, not enumerated among the sponges of the British coasts.
The diagnosis of this sponge given in Latin by Schmidt (7. c.) is short and conclusive, viz.:—‘ Halisarca obscure violacea irregulariter plicata et lobata.”’
On the following day I fed this specimen of Halisarca lobularis with indigo; and although it only took in this par-

tially, so as to become deeply coloured here and there, it was quite sufficient for me to be able to distinguish the spongozoa from the other parts of the structure &c., as will be seen here- after. Meanwhile, as Schmidt’s description is rather meagre, and the sponge would appear not to have been noticed on our coasts before, it may not be unacceptable to some to have the following description of the specimen that I have just found on the south coast of Devon.
Halisarca lobularis, Schmidt.
General form.—Sponge lobate, consisting of irregularly lobed ridges about a line high, extending themselves in branched digitations over the rock and adjoining sponges. Lobes ficoid, agglomerated, divided into minute lobuli with angular pits or intervals, between them where they cannot, from their rounded form, come into contact. Surface smooth, sleek, and of a pink colour on the prominent portions, passing into ight brown-yellow below. Vents sparse, situated here and there on the lobes, not raised above the surface, and sufficiently large to be visible to the naked eye. Pores minute and numerous, each consisting of a round aperture situated in the centre of a papilliform rimg—which rings being in juxtaposition, thus form the dermal surface of the lobule.
Internal structure composed of spongozoa, aggregated into sac-like forms of various shapes and sizes, some of which are distinctly conical elongate, and have their narrow ends respectively in connexion with a canal leading inwards from the pore, imbedded in a kind of trama consisting of sarcode (filamentous ?) and granuliferous cells, but with their confines neatly defined by a translucent linear interval; also of pore- canals forming a network extending inwards from the surface, and of a branched system of excretory canals terminating in the vents. No spicules of any kind, but here and there small globular masses of minute uniform granules possessing a nucleus (nuclear utricle), and small spherical opaque nucleus (nuc- leolus), with germinal spot or vesicle, no doubt ova. Pink colour confined to the spongozoa in the prominent parts of the lobes, whereby their sac-like aggregations here become more distinctly differentiated.
Size of specimen about 14 inch long by 1 inch wide and 1 line high. Pores of the specimen in spirit 1-1660th inch in diameter; papilliform circles surrounding them from 13- 2-830ths inch in diameter. Vents variable in size, but large enough to be seen by the unassisted eye.
Hab. New Red Sandstone rocks, lower surface; between tides.
Loc. South coast of Devon, Budleigh-Salterton.
Mr. H. J. Carter on Halisarca lobularis. 435
Obs. This specimen of Halisarca lobularis, of which the type was originally found by Schmidt in the Adriatic Sea at Subanico, does not differ from his description in any essential
oint. The pink colour on the prominent parts (stated by Schmidt to be “ dark violet’ in the Adriatic) goes very soon after immersion in spirit and water, where its original translucence is replaced by whitish yellow opacity.
The deep triangular puncta or interspaces between the lobules appear to be caused in the way above mentioned, and therefore lead to nothing ; while the surface of the lobules is formed of the papilliform openings of the pores, which are far too small to be seen with the naked eye, or even any thing below an inch compound power.
The most remarkable points about the pink colour are:—first, that it is exclusively confined to the spongozoa, whereby it would appear that the colour of sponges generally is seated in the spongozoa, as in Halisarca lobularis ; and, second, that by this pink colour in the living state the form of the sac-like aggregations of the spongozoa can be as distinctly seen as if the latter had been fed with indigo. Lower down, however, the absence of the pink colour renders this differentiation less evident ; while the presence of the indigo here, after the sponge has been fed with it, causes the differentiation to be more striking even than in the pink portions, where the latter colour somewhat obscures it.
Halisarca lobularis differs from H. Dujardinii in the follow- ing particulars, viz. :—H. lobularis, in the fresh state, is lobed and lobulated, tinted pink on the prominent parts, sleek on the surface, and provided with sparse vents on a level with the surface. H. Dujardinii, on the other hand, in the living state, is uniformly flat and even, of a yellowish grey colour, sleek on the surface, and sparsely provided with vents, which are projected above the level of the sponge by a short tubular prolongation of the dermal sarcode. Both may be charged with ova after the manner of sponges generally, as some spe- cimens of the latter from the Isle of Man (lately sent to me by my friend Mr. Higgin, of Liverpool) testify.
Having already found two specimens of ZH. lobularis, and knowing now what to look for, viz. a pink colour, lobulated form, and sleek shining surface, I dare to say that I shall often meet with it.
Of course Schmidt’s diagnosis of Halisarca, viz. that it possesses neither siliceous nor calcareous spicules, obtains with Halisarca lobularis.
436 Mr. H. J. Carter on the
Ampullaceous Sacs and Spongozoa. (Hackel’s ‘‘Gastrula” when developed zn situ ?)
In the ‘ Annals’ of 1857, vol. xx. p. 21, I published a description of the ‘‘ Ultimate Structure of Spongilla,” which appears to me, so far, to be typical of every other sponge, both marine and freshwater, that I have examined.
It was there that I first described and figured the “ ampul- laceous sac,” after having fed the Spongilla with carmine, and showed that this sac was composed of a pavement-layer of -monociliated cells (spongozoa) with a distinct and common aperture ; also that each spongozoon took in fragments of car- mine, while its cilium might be seen to vibrate in the cavity of the ampullaceous sac (/.c. pl. 1. fig. 5, &e.). The terms “sac” and “cell” involve the idea of a sac- and cell-wall respectively, which here must be maintained on inference rather than demonstration. There must be a “ vanishing-point”’ in early development; and to assume that a tissue cannot exist in such a subtile state as not to be appreciable by our senses, seems to me to be an untenable position. In this sense, therefore, I use the terms ‘‘ sac” and “ cell” for these sarcodal bodies respectively.
At p. 28 (/.¢.) it is stated (with reference to the undigested portions) that, ‘‘ after a certain time, the particles of carmine which have accumulated round the inner surface of the sac are gradually thrown off from its circumference, and falling into the efferent system of canals, are thus carried away and finally ejected.” It will be for us to consider, by-and-by, whether this takes place through the pavement-layer of the spongozoa generally, or at one particular point of the sac.
Lastly, in the ‘Annals’ of 1873, vol. xii., in my paper on the Gumminee, it is stated at p. 27:—“ I cannot help thinking that there are more species than Halisarca Du- jardinit to be found on our coasts ; so I hope to meet with not only this, but other species of the family here in a living state, through which I may, by experiment, be able to add some- thing more satisfactory to our knowledge of their intimate structure than we at present possess.”’
My anticipation in this respect will have been seen to have _ been realized in the discovery of Halisarca Dujardinti and H. lobularis on this coast ; while it so happens that by having fed the latter with indigo, still more precise information of the nature of the ampullaceous sac has been obtained.
By the above description of H. lobularis it will also have been seen that the ampullaceous sac is not only rendered more distinct by the presence of the indigo in the spongozoa,
Ampullaceous Sacs and Spongozoa. 437
but that it is rendered almost equally so in the most prominent parts by the pink colour of the spongozoa in the living con- dition of the sponge. Hence we have thus a distinct organ presented to us for consideration, viz. the ampullaceous sac.
And first, as regards its form in H. lobularis, this is irregu- larly round, but, in many instances, distinctly conical elongate ; for all these sacs are neatly defined, as before stated, by a translucent linear interval, which may thus be compared to the crystalline calespar that surrounds the brecciated fragments of a marble rock. To this translucent linear interval we shall return presently.
Meanwhile, taking the “ conical elongate ” sac, we thus have a fundus andaneck. The former, from its rounded contour, is clearly detined by the translucent linear interval; while the latter, from the presence of the indigo, shows (where the sac is close to the surface) that it is in direct continuation with the pore by a short tubular prolongation.
Further, it might be observed that the pore-canals branch off internally so as to form a reticulation, which, following the translucent linear intervals just mentioned, thus reaches the oral apertures, as they may be termed, of the more deep-seated ampullaceous sacs respectively.
From the pore on the surface to the ampullaceous sac we can thus trace the indigo and thence into the bodies of the spongozoa. And that the spongozoa are the only bodies which take in the indigo, may be inferred from its absence in all other bodies or cells of a like kind in the structure of the sponge.
Here the indigo remains, and hence the easiness with which we can make the demonstration. Not so, however, when the undigested portions are transferred to the excretory canal ; for here they are instantly discharged. Hence the difficulty of following their course from the interior of the ampullaceous sac to the excretory canal. In Spongilla, as before stated, I have seen this take place, but have never yet been able to pronounce whether the undigested particles of colouring- matter are transferred through the pavement-layer of spongo- zoa generally or at one specialized point of the ampullaceous sac.
If the former, it necessitates our assuming that the whole of the ampullaceous sac up to its neck is enclosed in a dilated extremity of a branch of the excretory canal-system; if the latter, that there is a specialized point in the ampullaceous sac, tantamount to an anal orifice, continuous with the branch of the excretory canal,
I incline to the latter, as being the most probable conjecture ;
438 On Ampullaceous Sacs and Spongozoa.
and if right, then we see the resemblance of the ampullaceous sac to the Ascidian, more especially of the compound Tunicata, in so far that each has an oral and an anal aperture.
““ Very good,” it may be stated ; ‘‘ but what have you in the Ascidian to compare to your individualized spongozoa, each of which appears to be a distinct animal?”
In reply to this I would observe that if among the com- pound Tunicata (which, being of the same habitat as Halisarca, grow plentifully together) we select a species that, by its translucence, permits of the young or embryonal Ascidians of the group being viewed under a microscope throughout their development, we may see that, at one stage, the young Ascidian is almost identical in appearance with the ampullaceous sac— that is, that it is composed of a pavement of cells aggregated into a sac-like form. Finally the internal organs of the Ascidian are developed, and the sac acquires an oral and an anal aperture. But in the sponge—that is, in Halisarca (as we are now more particularly engaged with this sponge) —the cells of the pavement-layer pass into individualized animals, each of which takes in its proper nutriment, and probably possesses indi- vidually or conjointly its proper generative function ; for to assume that they do not possess the latter would be to assume that the isolated forms described and figured by the late Prof. James-Clark (‘ Annals,’ 1868, vol. i. p. 133, pl. v.) do not possess this power.
Thus the development of the ampullaceous sac is arrested, and the cells adapt themselves to that condition which ends in the evolution of a sponge ; while the sac and its cells in the development of the Ascidian go on to the evolution of a compound tunicated group.
To make this more intelligible it might be stated that if, by the theory of evolution, the monad passes up to man, the monadine cell could not, at the time of reproduction, have been identical with the human ovum, because it must have possessed specialized powers of self-nutrition and immediate generation.
At the same time the differentiation that takes place in the evolution of the variously formed cells composing respectively the organs of the human body, from the simple cell-form of the human ovum, points out differences almost as great if not as numerous as those in the animals between man and the monad.
Hence we see that an organic cell may be at one time one thing and at another another, arising simply from adaptation to the functions required. Thus the cell or spongozoon of the ampullaceous sac becomes an individualized animal,
Hints for Microscopy. 439
and the whole sac, with its oral and anal apertures, so far like an Ascidian ; while the sac with its pavement-lining of cells in the compound tunicated animal goes on unarrested to pro- duce an Ascidian. It is on this account that I have stated that there is a greater relation between the Sponges and the Ascidians than between the Sponges and the Corals, whose polypes have but one aperture for both purposes.
To produce the “adaptation”’ there must be, of course, a creative or directing power, which, being infinite, we can never comprehend,
I would here add, for the information of those who care to experimentalize on the living sponges by feeding them with indigo or carmine (magenta will not do, for it dyes all alike), that the portion of sponge must be taken from its habitat without injury, put in sea-water directly, kept there until the following day (forenoon); the water then changed, and the indigo or carmine added by having been rubbed off a cake of one or other of these substances in sea-water, and dropped upon the sponges, where it should be allowed to re- main about an hour, always remembering that the experiment will be unsuccessful if it be not previously ascertained, by the ejection of particles from the vents (which can be seen under a 1-inch compound power), that the sponge is living and active. Portions may then be examined microscopically, after which the sponge should be placed in spirit and water for doing this at convenience.
A priori it might be considered desirable to have the sponge as fresh as possible; but experiment has taught me otherwise, viz. that to get the cilia retained with the indigo still in the body of the spongozoon, the sponge should be kept for a day first, in the way above stated, whereby, being weakened and hungry perhaps, the experiment is more likely to succeed.
Then, of course, the best plan is to examine a portion while the sponge is yet alive; after which it may be placed, as above noticed, in spirit and water for more deliberate obser- vation. In this state, too, a portion may be torn to pieces on the slide, dried and mounted in balsam, when, in many instances, the general form of the body and cilium will still be retained; or the fragments may be dyed with magenta, when the cilium will become still more evident; but, of course, what will render the transparent sarcode visible, will be likely to obscure the particles of indigo. Lastly a fragment having been torn to pieces on the slide in water, it may be simply dried, when the cilium will become more evident than in the wet state.
440 Mr. F. Smith on the Genus Eulema.
In examining minute objects, it is very desirable to acquire the power of holding a lens with the eye after the manner of a watchmaker; this, besides giving as it were a third hand, enables the operator, by means of a very high power, to pick out objects from material spread over the slide, through the aid of a subjacent mirror or black ground, and thus turn them over and over so as to obtain a view, under a compound power, of all parts of the object, such as it might be difficult, if not impossible, to get under any other circumstances.
Again, the microscopist should also endeavour, when he has got the focus of the “ fine adjustment,” to render it still. finer by gently pressing down the tube, whose resiliency, up and down, will thus give the observer a better idea of a minute object than any other means. Indeed it is absolutely neces- sary with very minute objects.

Mr. F. Smith on the Genus Eulema. 441
The above characters are those of the type of the genus, Eulema dimidiata. This genus can only be separated from that of Zuglossa by an examination of the oral organs. I have failed to observe more than two joints in the labial palpi; and upon this circumstance alone have I kept it separated from Euglossa. The characters given by St.-Fargeau are not reliable ; and the difference which he alludes to in the neuration of the wings has no existence; in both genera the neuration is the same. The labrum varies slightly in the species, being sometimes square, sometimes slightly narrowed anteriorly ; the males in both genera have the posterior tibie thickened, being convex outwardly. The scutellum is sometimes flat, sometimes a little convex; it has frequently a fossulet at its posterior margin, or a depression, the sides of which are elevated so as to become bituberculate.
The insects belonging to this genus, Mr. Bates informs us, are solitary in their habits. In the second volume of the ‘Naturalist on the River Amazons’ he observes of Ewlema surinamensis :— This species builds its solitary nest in crevices of walls or trees; but it closes up the chink with fragments of dried leaves and sticks cemented together, instead of clay. It visits the cajti-trees, and gathers with its hind legs a small quantity of the gum which exudes from their trunks ; to this it adds the other materials required from the neighbouring bushes, and when laden flies off to its nest.” The dilated posterior tibie, fringed at the sides, and thus forming a basket (similar to that on the legs of the hive-bee), has led to the supposition of the insects of this genus being social; but direct observation proves the contrary. These bees are furnished with two spines at the apex of the pos- terior tibiz, which none of the permanently social genera pos- sess. The genus Bombus, which is temporarily social, has spines similar to the genera Hulema and Euglossa, and has also the posterior tibia expanded and fringed at the sides in the same manner as those genera. Thus we have a gradation in structure, as well as in habit, from Hulema to Euglossa, and thence on to Bombus and the genera Melipona, Trigona, up to the genus Apis.

Above olive-brown, many of the feathers rather inclining to clearer and more rufous brown on their margins ; wings uniform with back externally, the inner webs of coverts and quills deep brown, the primaries very pale fulvous brown on their outer webs; tail uniform with back; crown of head light bay; lores, cheeks, and region of the eye bare; ear- coverts, throat, sides of neck, and hinder part of latter forming a collar pale creamy fulvous; under surface of body rather lighter olive-brown than the back, greyish on the abdomen, thighs, and under tail-coverts; under wing-coverts olive- brown like the breast, except the greater series, which are greyish like the inner lining of the wing. Total length 15°5 inches, culmen 1:1, wing 9°7, tail 3°5, tarsus 2°45.
Hab. Trinkut Island, Nicobars.
This new species is closely allied to I. nicobariensis, as might have been expected; but on examining the excellent account of the latter bird lately published by Mr. Hume (‘Stray Feathers,’ ii. p. 276), it is evident that the Trinkut bird is distinct. It has none of the “ French-grey” tinge on the throat and sides of neck, but, on the contrary, has these a a pale fulvous colour, forming a collar round the hind neck.
LXIV.—On the Skeleton of the New-Zealand Pike Whale, Balenoptera Huttoni (Physalus antarcticus, Hutton). By Dr. J. Hi. Gray, F.R.S. &e.
{Plate XVIII. ]
THE skeleton of the whale of which Professor Hutton’s account and figure are given in the ‘ Annals’ (ante, p. 316, Pl. XVI. a), from Otago Head, has arrived at the British Museum. It is in a very perfect state and beautiful condition, wanting only one ear-bone, which Professor Hutton says he will send at the next opportunity.
the New-Zealand Pike Whale. 449
It proves to be a species of the Pike Whale (Balenoptera), the Australian representative of the Pike Whale of Northern Europe, but perfectly distinct from it, and probably smaller than the European species ; for though the skeleton is that of a young whale, the bones of the specimen sent are generally well knit, the epiphyses of only a few of the cervical vertebrae are free; the lateral wings of the atlas and the edge of the scapula are imperfectly developed. It differs from the Euro- pean species in the larger size of the head, the fewer vertebra, and the longer fingers compared with the length of the fore- arm.
Professor Hutton gave the name of Physalus antarcticus, Gray, to this species, thereby intending the Balenoptera ant- arctica mentioned by me in the ‘ Zoology of the Erebus and Terror,’ p. 51, and founded on some yellowish-white Finner- baleen imported from New Zealand. But this baleen must come from a very much larger species of true Finner; for it is much broader compared with its length. The New-Zealand Finner is not to be confounded with the Balenoptera antarctica, Van Beneden (Ostéog. Cét. p. 234), which name he gave to the gigantic Sibbaldius antarcticus described by Bur- meister from Buenos Ayres (Proc. Zool. Soc. 1865, p. 713, figs. 1 & 2; Gray, Cat. Seals and Whales, p. 381, fig. 87), which Malm has named Physalus antarcticus. The bladebone of this species is 6 feet broad and 3 feet high. The bladebone of the Otago Pike Whale is only 15 inches broad and 9 inches high; and it differs from that figured by Burmeister not only in size, but in the glenoid being much more oblong, and in the shape and direction of the coracoid and glenoid processes.
It is necessary to refer this species to the genus Balenoptera and give it a new specific name, as Balenoptera antarctica is already used by Van Beneden. I therefore propose to call it Balenoptera Huttont.
The genus Balenoptera may be divided into two sections, thus :-—
* BALANOPTERA, Vertebre fifty; cervical vertebree some- times ankylosed, with the neural canal broad, trigonal ; fingers scarcely the length of the forearm-bone. J. rostrata: northern seas.
*® DactyLmna. Vertebre forty-eight; cervical vertebree quite free, with the neural canal broad, oblong, low ; fingers the length of the forearm-bone. B. (D.) Huttond: Antarctic seas.

Dorsal fin erect, compressed, about two thirds the entire length from the nose. Skull about one fourth the entire length. Baleen elongate, triangular, much longer than broad. Vertebre forty-eight; neural canal of cervical vertebree broad and low, transverse; ribs 11 . 11, first simple-headed. Pectoral fin moderate, the middle finger as long as the forearm-bone.

t, xvi. A (not Gray, ‘ Voy. Erebus and Terror’).
Hab. Southern New Zealand, Otago Head.
The skull is elongate, 46 inches long, 50 inches over the curve, and 22 inches wide in front of the orbits. The back of the brain-cavity slopes forwards from the foramen magnum nearly to the nasal bones. The beak is 82 inches long from the back edge of the nasal bones, slightly arched, and gradually tapers from the front of the orbit to the tip; the sides of the maxillary bones are nearly straight or very slightly concave. The intermaxillaries are narrow, rather broader in the middle of their length, flat on the front part, and concave on the sides of the blower.
The skull greatly resembles that of Balenoptera rostrata, especially in the form of the intermaxillaries and the concavity at the hinder part of them.
The nasal bones solid; the pair above elongate, triangular, nearly twice as long as broad, flat at top behind, and shelving off on each side in front, leaving an angular keeled central ridge, which is square at the top, broader below, 43 inches long and 34 inches wide.
The lower jaw is strong, curved, 44 inches long, and has a distinct conical tapering coronoid process.
The palatine bones at the end of the underside of the upper jaw are oblong, four-sided, longer than broad; they are truncated, but rounded on the outer side of the front edge, and united by a straight median suture ; they are attached by a large broad laminar suture to the pterygoid bones behind. These bones are much larger and broader than those of the Rorqual du Cap, Cuvier, ‘Oss. Foss.’ v. p. 370, t. xxvi. fig. 3d; and they are much broader and larger than those of Balenoptera Schlegelii figured by Van Beneden, ‘Ostéogr. Cétacés,’ t. xiv. fig. 2.
“The palatine bones are generally large in the Mysticetes, and the pterygoid bones are very small and widely separate ; but in the New-Zealand Pike Whale they are larger than usual. The development of the palatine bones is one of the characters which separate the whalebone-whales from the

toothed Cetacea (Denticetes). In the porpoise the palatines merely form a band between the maxille and the pterygoid bones; but they vary in size in the different genera, being larger in some, as Platanista; they are very small, and the pterygoids large in Hyperoodon (Cuvier, Oss. Foss. v. t. xxiv. fig. 19,g &h); and they are large in Catodon (Cuvier, Oss. Foss. v. t. xxiv. fig. 1,m & n), where they approach nearer to the shape of those of the whalebone-whales.
One (the left) ear-bone is attached to the skull, and appears to differ from the ear-bones of Balenoptera rostrata figured in the ‘Catalogue of Seals and Whales in the British Museum,’ p- 191, fig. 56, in being shorter ; but it cannot well be seen, as I do not wish to detach it from the skull.
The baleen is elongate, triangular, longer than broad at the base—when dry, horn-coloured, blackish on the straight edge, whitish on the inner hairy margin and at the tips. A blade is 15 inches long, and 2 inches wide at the base; but there are some rather larger.
The vertebree are 48—cervical 7, dorsal 12 (with eleven pairs of ribs), lumbar 13 (with lateral processes, without any perforation at the base), caudal 16 (with only rudimentary lateral processes or none, and a perforation at base). There are seven chevron bones ; but it is not quite certain that they are perfect.
Ribs eleven pairs. The first rib with a single head, and a broad sternal end; the other ribs slender, curved, all similar.
The cervical vertebre are seven, all free. The atlas with a blunt broad process on each side; the axis thicker, with a keeled, wide, hood-like process above, the lateral processes abbreviated, leaving a broad rounded notch, most probably elongate when complete. The second, third, fourth, and fifth cervical vertebree have a process from each lower side of the body. The processes of the second, third, and fourth are com- pressed, rather dilated at the ends, and rather produced at the upper margins of the end; those of the fifth are cylindrical, rather swollen at the ends ; and there are only rudimentary ones on the sixth and seventh. ‘The bodies of the vertebra are oblong, four-sided, broader than high. The neural canals oblong, transverse ; of the axis smaller, more rounded ; of the other cervical vertebrae wider and lower, nearly as broad as the bodies of the vertebree, and in this respect very different from the canal of the fifth cervical vertebra of B. rostrata, figured in the ‘Catalogue of Seals and Whales in the British Museum,’ fig. 51.
“iPhe sternum broad and expanded in front, and with a short stem behind; the front edge rounded, with a slight

notch in the middle, and with rounded ends. The sternum is 61 inches broad, 5 inches long; the hinder part thick, cylin- drical, about 23 inches long, very different from that ot Balenoptera rostrata figured in the ‘Catalogue of Seals and Whales in the British Museum,’ p. 110, fig. 12, c, more like the sternum of Balenoptera musculus, Van Beneden (Ostéogr. Cét. t. xii. fig. 14) ; but the upper part is more expanded, the central notch rudimentary, and the stem longer and more slender.
The os hyoides is 8} inches wide and 3 inches long, dilated in the middle, with a notch in the front edge somewhat as in Balenoptera rostrata (Ostéogr. Cét. t. xu. fig. 4), but more dilated in the middle, and with a process on each side of the notch, to which is attached a flattened bone. M. van Beneden does not figure any processes to the os hyoides of any of his species in the ‘ Ostéographie’ similar to those found in the skeleton from Otago.
The scapula broad and low, the upper edge being about one third of a circle, with well developed acromion and coracoid processes. The glenoid cavity large, oblong; the coracoid blunt; the acromion process coming from a ridge which extends up the upper margin, elongate and broad. ‘The width 15 inches, the height 9 inches; the glenoid cavity 4} by 28 inches. The scapula is rather broader and lower, and has a smaller acromion process than that of B. rostrata figured by Van Beneden (Ostéogr. Cét. t. xii. fig. 6).
The bones of the fore fin are 28 inches long; the humerus 6 inches, the ulna and radius 10 inches, the longest finger 10 inches. The first finger with three bony joints and one cartilaginous one, the second with seven, the third (longest) with eight, the fourth with four joints.
There were sent with the skeleton a pair of ear-bones of another Finner; but they cannot belong to this skeleton, as the skull has the left one attached, and Professor Hutton in- forms me that one was unfortunately left behind, but it is on its way to the Museum. ‘The pair of ear-bones sent are very like those of Megaptera nove-zelandie, ‘Catalogue of Seals and Whales,’ p. 128, fig. 20.

The only two specimens of this species which I have seen belong to the Turin Museum, and were brought by the Marquis Giacomo Doria from Hamaddn. The keeled imbri- cate scales beneath the tail and legs serve to distinguish it from all allied forms.
Bunorpvs, gen. nov. (vel subg. Gymnodactyli). Genus inter Gymnodactylum et Stenodactylum fere medium, cum

Hab. haud procul a Bandar Abbas juxta litus sinus Persici (Doria).
A single specimen was obtained near Bandar Abbas by the Marquis Giacomo Doria, who informs me that it was found on the sand of a torrent-bed. This specimen belongs to the Turin Museum ; and I am indebted to the kindness of Count Salvadori for the loan of it and of Gymnodactylus heterocercus for description.
A somewhat similar arrangement of imbricate scales beneath the toes is found in the West-African Stenodactylus caudi- cinctus, C. Dum. This is a very different form, having affinities to Hublepharus. It is the type of Pstlodactylus, Gray.
AGAMURA, gen. nov.

8. Agamura cruralis.
A, grisea fusco transversim fasciata; dorso granulato, granulis yix conyexis tuberculisque majoribus frequentibus instructo ; membris elongatis, pede posteriore oculum attingente, haud tuberculatis, nisi interdum supra femur; capite brevi, alto, supralabialibus utrinque 12-14, meatu auditorio mediocri; cauda verticillata in- ermi, subtus serie unica scutorum polygonalium majorum in- structa ; poris inguinalibus in maribus duobus.
Hab. inter lapides in Gedrosia haud frequens.
This is a remarkable form allied to Spatalura Carter?, Gray, and forming with it a distinct subfamily of Geckoes, distin- guished by their very different tail, which is very flexible and apparently never reproduced. In Spatalura the tail is com- pressed and fringed above and below.
A second species of Agamura is Gymnodactylus persicus, C. Dum., very closely allied to A. cruralis, but distinguished by having rather shorter limbs, smaller ear-orifice, the upper part of the thigh and front of the tarsus tuberculate, and the rostral shield vertically divided.

LX VI.—New Observations on Eozoon canadense.
By Wiuu1aM B. Carpenter, M.D., LL.D., F.R.S. [Plate XIX. ]
Ir may be thought that Mr. Carter would have best consulted, not only the interests of science, but his own reputation, by abstaining from any further attempts to disprove the Forami- niferal nature of Hozoon, until he had either acquainted him- self with the careful descriptions and “ fac-simile ” representa- tions of its structure given by Dr. Dawson, Prof. T. Rupert Jones, and myself*, or had satisfied himself, by an examina- tion of the specimens which I expressed my readiness to show him, of the fallaciousness of my interpretation. But I make no complaint of his having chosen the opposite course, since his adoption of it has led me to a careful re-examination of the whole subject, with the result of not only removing a dif- ficulty [had myself felt, and of thus strengthening my own con- viction, but of enabling me (as I anticipate) to carry that conviction to the mind of every competent judge, who has not so completely made up his mind to a foregone conclusion as to be unable to appreciate the force of the new evidence I have now to produce.
I shall first dispose of the objection which Mr. Carter ad- duces as fatal to the Foraminiferal doctrine, viz. that the supposed nummuline tubuli frequently lie parallel to the chamber-walls, instead of perpendicular to them—a character which, says Mr. Carter, “is utterly incompatible with Fora- miniferal structure.” This dictum, when translated from Carterese (p. 278) into English, merely means that it is incompatible with Mr. Carter's notions of Foraminiferal structure; to which, as I have already had occasion to show, Nature refuses to bind herself. I fully admit the fact as he states it, and now find a perfectly simple explanation of it in the structure of those very Nummulites which Mr. Carter knows so well. In the lower or “lamellar ”’ portion of the Canadian Eozoon, the nummuline tubulation (where preserved) always presents—so far as my experience extends—its normal perpen- dicularity to the surface of the chambers; as shown in Pl. XIX. figs. 1,2. The arrangement referred to by Mr. Carter presents itself only in that upper or “ acervuline ’’ por- tion, in which, as in many recent I’oraminifera, the chamber-
* The “constructed ” figure which I introduced for mere convenience of reference, was built-up (as every one of my ‘‘ constructed” figures has been) from parts which were separately described and figured ten years ago from the actual specimens, for the sake of showing the relations be- tween them,—a method used by every Palzeontologist.

lets are irregularly piled one on the other (see p. 281, fig. 1) ; and the parallelism of the tubuli to the walls of the chamber- lets they adjoin, simply arises from the fact that they are passing-by these, in that perpendicular course from the cham- berlets in which they originate, towards the external surface, which Mr. Carter himself recognizes as perfectly normal. This is shown in the subjoined figure (a) traced from a trans- parent section in my possession—the precise counterpart to at (6) being shown in those Nummulites which have the “ alar

prolongations” of successive whorls prolonged over those which preceded them, so as to be piled one upon another, often dividing themselves into irregular chamberlets. _ For when these are laid open by vertical section, it continually happens that the tubuli coming off vertically from the chambers of an inferior plane, lie parallel to the sides of the chambers of the plane above them ; so that, if the chambers and tubuli were infiltrated with serpentine, and the calcareous skeleton were removed by acid, the appearance presented would be exactly that figured by Messrs. King and Rowney, which Mr. Carter, with all the weight of his authority, pronounces to be “ wtterly incompatible with Foraminiferal structure.”—That I have not evolved this parallelism out of my own consciousness, will be manifest to any one who may take the trouble to refer to the admirable plates of Nummuline structure given by MM. D’Archiac and Haime in their ‘ Animaux Fossiles du Groupe Nummulitique de l’Inde.’ For it is distinctly seen in every one of their thin vertical sections of those species in which the “alar prolongations” are conspicuous—as N. intermedia,

Thus, so far from Mr. Carter’s case of utter incompatibility proving fatal to the Foraminiferal doctrine of Hozoon, a “‘ com- parison of the actual specimens” (his own test) gives to that doctrine the additional support of @ very striking conformity. Speaking for once in Carterese, I might say that Mr. Carter has “ found a mare’s nest.”
Professors King and Rowney, also, in their anxiety to put me in the wrong as regards the Foraminiferal relations of Hozoon, have only betrayed their own ignorance of Foraminiferal structure, to a degree that must (I should think) shock even their ally Mr. Carter. ‘ We have shown,”’ they say (p. 393), “that the relative position of two superposed acicular layers (an upper and an under ‘nummuline wall’), and the admitted fact of their component aciculee often passing continuously and without interruption from one“ chamber-cast’ to another, to the exclusion of the ‘intermediate skeleton,’ are totally tn- compatible with the idea of the said ‘nummuline layers’ having resulted from pseudopodial tubulation.” Now, putting aside the first part of this statement, which betrays the con- fusion existing in the minds of its writers between the true “ nummuline layer,” as described by me from transparent sections, and the “ acicular layers’ of decalcified specimens, which may or may not represent it (see p. 461),—what must be said by Mr. Carter of the second? For he, of course, knows perfectly well that in the superposed whorls of Nummu- lites, as described by me in 1849, and in the superposed layers of Orbitoides, as described by him- self in 1861, the pseudopodial tu- bulation normally passes on ‘ con- tinuously and without interruption from one chamber to another, to the exclusion of the ‘intermediate skeleton.” This is represented alike in my original figures of the
Oi “Nummuline tubulation” (Quart. Vertical Section of co- J saan ame caa: 185 lumns of Orbitoides yourn. 0 cor. oelety. Sy 850), dispansa; 1, column in every one of D’Archiac and of chambers; 2, ver- Haime’s vertical sections of Num- tical tubuli of the test; mulites, and in Mr. Carter’s own neers

It was doubtless the apparent force of the argument whose fallacy I have thus demonstrated, which led Prof. Max Schultze, after reading the paper of Professors King and Rowney, to write to Mr. Barker that it had “made a very great impression” on him, and that “ with respect to the ‘ proper wall’ of Carpenter” he was “ entirely of their >a I have no reason to believe that Prof. Max
chultze ever did see the “ proper nummuline wall,” such as I shall presently describe and figure it; Professors King and Rowney certainly have not, it they can identify it with a film of chrysotile or asbestiform serpentine, forming “an integral portion of the grains and plates of serpentine,” and can assert that in its typical condition it occurs in cracks or fissures of the serpentine (p. 393); and they misled Prof. Schultze into the belief that they and I were speaking of the same things. When I sent him the preparations he asked for, I expressed my regret at not being able to supply him with a characteristic specimen of this structure, having given away all the duplicates of it I could spare; and, as it is rarely well-preserved, it is very probable that he did not find it by his own examination of the larger specimens he afterwards received from me and from other sources. At any rate, there is no mention of the “nummuline wall” in his communica- tion to the Wiesbaden Association—his acceptance of Hozoon as a Foraminifer entirely resting on the “ canal-system,” which he had minutely studied*, and as to which there zs no evidence whatever that he had changed his opinion, as asserted by Professors King and Rowney. Had he lived to see what I shall presently describe, I cannot doubt that he, in common with the numerous Microscopists to whom I have recently shown it, would have accepted the “ nummuline wall” with- out the slightest hesitation.
Before, however, I proceed to describe it, I find myself obliged to notice the following statement made by Professors King and Rowney in the second note to p. 393 of their last paper :—
* Mr. Carter questions the existence of a canal-system in Polytrema, referred to by Prof. Schultze, because his own ‘‘ mounted specimens” do not show it. When he has extended his knowledge of Foraminifera by the careful study of my “ Introduction” and of the types minutely de- scribed in it, he will find that the development of the “ canal-system ” is correlated to that of the “intermediate skeleton,” and that varietal or even individual differences may occur in this particular. I had never myself seen it in Planorbulina (for example), until M. Munier-Chalmas showed it to me, a few weeks since, in a specimen in the Sorbonne Mu- seum. This specimen had grown so closely attached to a Coral, as to have shaped itself on the inequalities of the Coral-surface ; and yet its lower or attached side was as perfectly tubulated as its upper or free side—a fact which I commend to the consideration of Professors King and Rowney.

“The so-called ‘nummuline wall’ in Dr. Carpenter’s con- structed representation, fig. 2, ought not to be represented in the way it is—bounded by two continuous lines—as it is an integral portion of the grains and plates of serpentine (the so-called ‘ chamber-casts’), and not a chemically differentiated part like the true calcareous wall of certain Foraminifers.” I have represented nothing that my specimens do not dis- tinctly show ; and the only excuse for such an imputation can be, that those who made it have never seen the true ‘‘“nummuline wall,” such as I figured it ten years ago, be- fore a question had been raised as to the organic nature of Eozoon (Quart. Journ. Geol. Soc. vol. xxi. plate viii. figs. 3, 4), and such as I now again figure it from a still better specimen in Plate XIX. figs. 1, 2. Professors King and Rowney, merely because they have not met with what I have repre- sented, take upon themselves to deny its existence.
My érue “nummuline wall” is the representative of that which, in recent Foraminifera, immediately surrounds the chambers (Pl. XIX. fig. 1, aa). It is not a layer of chry- sotile acicule ; but is a calcareous lamella, perforated by minute tubuli, which usually lie straight and parallel, but are often more or less curved. These tubuli, like the chambers and canal-system, are usually filled with serpentine, which has passed into them from the chambers in which they originate ; and thus it happens that the original tubulation is generally ob- scured, being only represented microscopically by the differ- ence in refractive index between the calcareous shelly layer and the serpentine which has filled its tubes,—just as in a specimen of fresh bone or dentine mounted in Canada balsam the tubuli are only represented by the different refractive in- dices of the matrix and the balsam. But in the specimen of Eozoon figured in Pl. XIX. figs. 1, 2, many of the tubuli re- main empty; and they can be distinguished as tubuli under any magnifying-power that the thickness of the covering-glass allows to be used. Further, they have the somewhat sinuous course of the tubuli of organic structures; and they present, at what was probably a plane of interrupted growth, the sharper flexures which Prof. Owen first pointed out in the tubuli of dentine, and which I described and figured twenty- seven years ago in the hard dentine-like substance of the end of the Crab’s claw*.
That the matrix m which these tubules are channelled out is calcareous, is shown in this section by the extension into it of the planes of crystalline cleavage (fig. 1, ¢ c) of the ‘ cal-

careous layer, representing the intermediate skeleton,’ with which it is continuous. And it is shown also by the effect of dilute acid on any true ‘“‘nummuline layer’ of which the tubules have been filled with serpentine ; for it is only after the removal of the calcareous matrix that the internal casts of its tubules, remaining as separate acicule, present the least resemblance to the chrysotile fibres to which Professors King and Rowney persist in likening them, notwithstanding my repeated assertions that the two things are altogether different. I can show a precisely similar arrangement of vertical aciculz on the surface of a chamber-cast of a recent Amphistegina, and know them to be the internal casts of the tubuli of its Nummuline wall. But Professors King and Rowney’s argument would make out these also to be mere products of mineralization, because they resemble chrysotile-fibres. I am perfectly acquainted with the mineral pseudomorphs to which they refer, and freely admit their resemblance to certain forms of the “ acicular layer”’ left after the decalcification of the “ nummuline layer ;” but I cannot believe that any microscopist who is familiar either with dentinal or any other form of tubulation, can entertain the slightest doubt that if figs. 2, 3 be correct, the unaltered structure they represent is organic. If it be one that any kind of mineralization can produce, I do not see why we are to call Bones and Teeth any thing else than in- organic concretions. The only alternative hypothesis is, that not only Mr. George West and I, but all the Microscopists who have verified our representation, are suffering under “tubulation on the brain;” and this the Galway Professors and Mr. Carter are quite welcome to assert, if they think pro- per, when they shall have examined the specimen itself, which is open to their inspection at any time. At present they are in the position of the opponents of Galileo, who would not look through the telescope which showed the Satellites of Jupiter.
I now pass on to a second probative fact of at least equal cogency,—the relation exhibited in the same specimen be- tween the “ canal-system”’ and the tubuli of the ‘ nummuline layer.”
we my original description of Calcarina (Phil. Trans. 1860)—the type to which, as regards the general distribution of its canal-system and its relation to the intermediate skeleton, Eozoon has the closest resemblance—I gave the following account of that relation (p. 554) :—“ The proper walls of the chambers are uniformly perforated, like those of the chambers of Rotalie, by foramina of considerable size (averaging above 1 3000th of an inch in diameter) ; with these the canals of the
462 Dr. W. B. Carpenter on Kozoon canadense.
supplemental [or intermediate] skeleton do not seem to be directly continuous, for they are of about double the diameter and lie further apart from one another ; but immediately round the proper wails of the chambers there seem to be irregular lacunar spaces, into which the foramina open externally, and from which the passages of the canal-system originate.” Now, in my “ Supplemental Notes on the Structure and Affinities of Hozoon canadense” (Proceed. Geol. Soc., Jan. 10, 1866, p- 222), I stated that precisely the same relation is shown to exist in decalcified specimens of Hozoon, by the implantation of the dendritic models of the chamber-casts in plates formed by the coalescence of the acicule that occupied the tubules of the “ proper wall.” Having now been fortunate enough to meet with a transparent section which exhibits this relation most unmistakably (Plate XIX. fig. 1, 6b), I fearlessly ask the verdict of any Biologist familiar with microscopic structure, whether any more exact realization could be presented of the structure I had described in Calcarina,—allowance being of course made for the different scale of the tubulation of the “proper wall,” which is here jine “ nummuline”’ not coarse * rotaline.”’
There is another feature in the canal-system of this speci- men, which, by leading me to a more careful examination of its ordinary distribution, has brought into view what seems to me a new point of difference between the typical canal-system and mineral dendritic ramifications. It will be observed that the principal trunks are here in the middle of the calcareous layer, the ramifications extending from them towards each of its surfaces. This, of course, cannot be so clearly brought out in any plane section, as it can be in such decalcified spe- cimens as are represented in figs. 3,4; in which a set of canals are seen to originate from the ceiling of the chamber beneath them, and to converge like the roots of a tree into a stem, from which diverging branches are given off towards the floor of the chamber above. Now, in all dendritic ramifications I have seen (I do not presume to speak with confidence of things I have not seen), the branches go off from a main trunk which originates at once from the source of the infiltration, instead of being formed by the coalescence of roots*. I do not lay any stress on the Tene but this peculiar distribution of the canal-system is not without its significance, in regard to the
* As I was accustomed to see dendrites made at a Pottery in Bristol forty years ago, I am not quite so ignorant in regard to them as Professors King and Rowney seem to suppose that I must be, from the fact that I am a Biologist and not a Mineralogist. The process was simply this :— The cylindrical “ biscuit” beer-cup (sold for a penny) having been dipped

mode in which it ministered to the deposition of the inter- mediate skeleton.
The third of the additional probative facts I have now to adduce is the existence of a canal-system in the calcareous lamelle, anteriorly to the intrusion of any foreign mineral ; as is distinctly proved by the fact stated in my previous “ Re- marks”’ (p. 283), that the minuter part of the canalicular system is often not infiltrated with any foreign mineral at all. As I hold this fact to be of cardinal importance, and as I cannot see that it has been met, either by Professors King and Rowney, or by Mr. Carter, in their replies to my previous Remarks, I now present an exact representation (Pl. XIX. fig. 5) of the aspect of such a portion of the canalicular system—showing by its semi- opacity in one part the extent to which the serpentinous in- filtration has proceeded, and by its transparence in the rest that the canalization is not the result of any foreign infiltration whatever. These canals (as formerly stated, p. 283) are filled with calcite having the same crystalline axis as that of the matrix—just as is the reticular structure of fossilized skeletons of Crinoids, spines of Cidaris, &e. It would be just as logical to refuse to that reticulation the character of an organic structure, because it possesses (even in the recent state) a crys- talline arrangement, as to say that this canalicular system is not an evidence of the organic origin of the calcareous lamelle in which it presents itself. ‘ Is it possible,” said one of our most distinguished Naturalists to me a few days since, “ that it is seriously maintained that these canaliculi do not pre- exist ?”” As I know them to be contained in the section which I long since forwarded to Prof. Rowney, the only conceivable reason for the non-recognition of them, alike by the two Galway Professors and by Mr. Carter, is that they have not used the reduced light, which, through the extreme transparence of the minuter canaliculi, is necessary to bring them into clear view.
I have thus shown :—(1) that the “ utter incompatibility ” asserted by my opponents to exist between the arrangement of the supposed “nummuline tubulation”’ of Hozoon and true Nummuline structure, so far from having any real existence, really furnishes an additional point of conformity ; and (2) that three most striking and complete points of conformity exist be-
in its viscid “glaze,” and held in an inclined position, a brush dipped in a viscid pigment was brought into contact with it at the proper point ; and the pigment ran down into the glaze, first forming a stem, and then spreading out in an arborescent ramification. The success of the opera- tion depends on a very nice adjustment between the viscidities of the two liquids.

tween the structure of the best-preserved specimens of Lozoon, and that of the Nummulites whose tubulation I described in 1849, and of the Calcarina whose tubulation and canal-system I described in 1860. And I leave it to the judgment of those who know the differences between Organic structure and any conceivable results of Physical or Chemical action, whether the appearances represented in Plate XIX., to the minute accuracy of which representation I pledge myself, are compatible with the doctrine that the Canadian Ophite is nothing more than a product of mineralization.
That I have not troubled myself to reply to the reiterated arguments in favour of that doctrine, which have been advanced by Professors King and Rowney on the strength of the occurrence of undoubted results of mineralization in the Canadian Ophite, and of still more marked evidences of the same action in other Ophites, has been simply because these arguments appeared to me, as I thought they must also appear to others, entirely destitute of logical force. Every scientific Palzontologist I have ever been acquainted with has taken the dest preserved specimens, not the worst, as the basis of his reconstructions ; and if he should meet with distinct evidence of characteristic organic structure in even a very small frag- ment of a doubtful form, he would consider the organic origin of that form to be thereby substantiated, whatever might be the evidence of purely mineral arrangement which the greater part of his specimen may present,—since he would regard that arrangement as a probable result of subsequent minerali- zation, by which the original organic structure has been more or less obscured. If this is not to be our rule of interpretation, a large part of the Paleontological work of our time must be be thrown aside as worthless. If, for example, Professors King and Rowney were to begin their study of Nummulites by the examination of their most mineralized forms, they would deem themselves justified (according to their canons of interpretation) in denying the existence of the tubulation and canalization which I described (in 1849) in the N. levigata preserved almost unaltered in the London Clay of Bracklesham Bay.
My own notions of Hozoze structure have been formed on the examination of the Canadian specimens selected by the ex- perienced discrimination of Sir William Logan, as those in which there was least appearance of nietamorphism; and having found in these what I regarded as unmistakable evi- dence of an organic structure conformable to the Foraminiferal type, I cannot regard it as any disproof of that conformity,
Dr. W. B. Carpenter on Eozoon canadense. 465
either to show that the true Eozoic structure has been fre- quently altered by mineral metamorphism, or to adduce the occurrence of Ophites more or less resembling the Hozoon of the Canadian Laurentians at various subsequent Geological epochs. ‘The existence of any number or variety of purely
mineral Ophites would not disprove the organic origin of the -
Canadian Hozoon—unless it could be shown that some wonder- ful process of mineralization is competent to construct not only its multiplied alternating lamelle of Calcite and Serpen- tine, the dendritic extensions of the latter into the former, and the “ acicular layer ”’ of decalcified specimens, but (1) the pre-existing canalization of the calcareous lamelle, (2) the unfilled nummuline tubulation of the proper wall of the chambers, and (3) the peculiar calcarine relation of the canali- zation and tubulation, here described and figured from speci- mens in the highest state of preservation, showing the least evidence of any mineral change.
On the other hand, Professors King and Rowney began their studies of Eozoic structure upon the Galway Ophite—a rock which Sir Roderick Murchison described to me at the time as having been so much “tumbled about,” that he was not at all sure of its geological position, and which exhibits such obvious evidences of mineralization, with such an entire absence of any vestige of organic structure, that I should never for a moment have thought of crediting it with an organic origin, but for the general resemblance of its Serpentine-grains to those of the “ acervuline”’ portion of the Canadian Eozoon. They pronounced with the most positive certainty upon the Mineral origin of the Canadian Eozoon, before they had sub- jected transparent sections of it to any of that careful compari- son with similar sections of recent Foraminifera, which had been the basis of Dr. Dawson’s original determination, and of my own subsequent confirmation, of its organic structure. And while Prof. Rowney never laid claim to any knowledge of Micro-Paleontology, the accuracy of Prof. King’s information in this department of inquiry may be estimated by the fact, that when (about the same time) he made his first acquaint- ance with the Orbulina universa brought up in the ‘ Porcu- pine’ soundings off the West of Ireland, he forthwith described them as not improbably affording the explanation of the gra- nular concretionary structure of Oolites.—That I did not shrink (as is imputed to me in Profs. King and Rowney’s last com- munication) from meeting them in their own selected field, will appear from the following statement.
When, about five years since, the Galway Professors pre- sented their Memoir on LHozoon to the Royal Irish Academy,
466 Dr. W. B. Carpenter on Eozoon canadense.
the Secretary of that body wrote to me, stating that its Members were desirous of forming their own judgment on the subject, and requesting that I would transmit specimens for their examination. I immediately replied, forwarding the two best duplicates I had to spare, with a request that after they had served their immediate purpose they might be presented to the Museum of Trinity College, Dublin; and I further offered to go over to Dublin and personally exhibit my own selected series of specimens (which I declined to part with out of my hands) if I could obtain a short leave of absence from my official duties. Not receiving any acknowledgment, either of my specimens or of my proposal, I wrote a second time to the Secretary, and again waited in vain fora reply. I then wrote to the President of the Academy, stating the purport of my previous communications to its Secretary ; but as he, too, deemed me unworthy of the honour of an answer, I thought it unadvisable to take any further action in so thankless a matter.
As the readers of these ‘Annals’ have never had placed before them the general evidence in favour of the organic origin of Hozoon, adduced by Sir Wilham Logan and Dr. Daw- son when they first brought their discovery before the Geolo- gical Society nearly ten years ago, I venture to ask their con- sideration of the following brief summary of the facts of this remarkable case, and of the ¢nferences which they seem to me to justify.
1. There occurs in the Lower Laurentians of Canada a stratum of “ Serpentine Limestone” or “ Ophite,” extending over several hundred square miles, and impressing the able Geological Surveyors of Canada with its resemblance to a Coral Reef.
2. Most Geologists now accept it as a probability, that the formation of Limestones generally is due, either directly or secondarily, to Animal growth; and the evidence of this doc- trine is continually accumulating. The antecedent probability that such was the case with the Laurentian limestone, is in- creased by the circumstance that beds of Graphite (which every Mineralogist now recognizes as of Vegetable origin) occur in the same formation—that many specimens of the Limestone give forth when struck the overpowering smell of carburetted hydrogen, which is well known to be given off from many beds of Carboniferous Limestone whose organic origin is most distinct—and that so strong a musky odour was emitted from the specimen of which I sent slices to Prof. Rowney and Prof. Schultze, when it was being cut in Mr.

Cuttell’s workshop, as to be almost unbearable.—These facts are not advanced as probative, but simply as affording confir- matory probabilities.
3. The arrangement of the two components of the Canadian Ophite is most remarkable, and extremely significant of some process of progressive construction. In the ordinary type there is a regular alternation of lamelle of Serpentine and Calcite, sometimes to the number of fifty of each—the thickness of the Calcareous lamelle being greater below, and progressively diminishing above, whilst that of the Serpentinous presents a singular uniformity throughout. When minutely examined, the Calcareous lamelle present appearances strongly sugges- tive to the Micro-Paleontologist of an organic origin, their crystalline cleavage being common to them with almost every calcareous fossil. On the other hand, the Serpentinous lamellee are seen to be formed by the coalescence of spheroidal seg- ments having a general uniformity of size (see fig. 1, p. 281); while in the upper part of every complete typical specimen, the arrangement of these segments in continuous lamelle gives place to an irregular piling of them together, the intervening calcareous walls being very thin.
4. Fixing our attention in the first instance on the Calcareous portion of this Ophite (fig. 2, p. 282), we recognize in it a general conformity to the Foraminiferal type,—the lamellated portion showing large “‘ chambers” formed by the coalescence of ‘“ chamberlets ;” whilst in the “acervuline” portion the chamberlets are isolated, still communicating with each other, however, by apertures through the calcareous septa resembling those of ordinary Foraminifera*.—This transition from a regular plan of growth to the “acervuline” mode is very common in Foraminifera, as must be known to every one who has studied my “ Introduction.” On the other hand, I have lately come into possession, through the kindness of M. Munier-Chalmas of the Sorbonne Museum, of a new fossil type of Foraminiferal structure belonging to the Orbiculine group, in which a partial coalescence (or subdivision) of chamberlets, like that of the lamellar portion of Hozoon, is very distinctly marked, so as to establish precisely the link of connexion which was wanting between the chambers of Peneroplis and the completely-divided chamberlets of Orbiculina. Thus, then, in the general arrangement of the Calcareous component of the Canadian Ophite, there is a marked conformity to the
* Mr. Carter denies the existence of these passages, simply because he did not find them in the one transparent specimen he examined. He can verify the representation of it given in fig. 2, bb (p. 282), whenever it may please him to come and examine my specimens.
468 Dr. W. B. Carpenter on Eozoon canadense.
Foraminiferal type. And this conformity is equally shown when (as happens in certain localities) the Calcite is replaced by Dolomite. I have frequently met with veins or dykes of the latter mineral running through the ordinary calcareous lamella; and there is obviously nothing wonderful in such conversion of the Calcite into Dolomite, either locally or gene- rally, when Magnesia in solution was largely present. But the co-existence of the same structural arrangement with a dif- jJerent mineral composition, strongly indicates (as Sir William Logan pointed out) the origin of that structure to le in some- thing else than a mineralizing process.
5. Turning now to the arrangement of the Serpentinous lamelle, and seeking for a ratéonale of their presence, we find it in the fact first pointed out by Prof. Khrenberg, then con- firmed by Prof. Bailey (who first showed it to be true of existing types), and verified by Prof. Rupert Jones, Mr. W. K. Parker, and myself, that the cavities of Horaminifera become occupied, without any process that can be likened to “ infiltra- tion”’ (since it takes place on the ordinary sea-bottom), by Glaucite or other silicates ; so that when their calcareous shells are dissolved away by dilute acid, perfect internal casts of their chambers are left. That this is the origin of the green- sands which occur in various Geological formations, from the Silurian upwards, is the well-known doctrine of Prof. Ehren- berg, which is based on the striking conformity between the forms of the particles of these sands and the chambers of known Foraminifera. And by that fundamental rule of Geo- logical interpretation, which requires us to explain every thing that we can so explain by reference to changes now going on, I hold myself fully justified in contending that the same pro- cess—whatever may be its nature—which is filling the cavities of existing Foraminifera with siliceous compounds, and which can be traced backwards as far as the Silurian epoch, may fairly be accepted as the rationale of the presence of the regular lamelle and acervuline segments of Serpentine in the Canadian Ophite, its caleareous interstructure having a close conformity to the Foraminiferal type. And here, again, the probability is strengthened by the fact that the same structure shows itself, alike in recent and fossil Foraminifera, with different minerals. My own recent specimens show it with at least two silicates, a green and an ochreous; and so, as Sir William Logan tells us, the chambers of Hozoon may be occu- pied with pyroxene or loganite, instead of with serpentine— the alternation of calcareous with siliceous lamellae, however, being always preserved.
6. The presence of Serpentine, however, is not limited to
Dr. W. B. Carpenter on Eozoon canadense. 469
the lamelle ; for it penetrates the Calcareous layers, exactly in the same manner that the Silicates which occupy the chamber-cavities of existing Foraminifera penetrate the walls of those cavities, extending into the canal-system of their “intermediate skeleton,” and even filling the minute tubuli of their “ proper walls,”—so as, when the calcareous skeleton has been dissolved away, to afford the most perfect models, not only of the sarcodic segments which occupied the chambers, but also of their extensions into the canal-system, and even of their minute pseudopodial threads. Now to all this I can show the most precise parallel in the Canadian Hozoon—even to those departures from the ordinary parallelism of the tubules, which I described in certain varieties of Operculina (Phil. Trans. 1859, p. 24). And I am fully justified, therefore, by the accepted rules of Paleontological interpretation, in assert- ing that whatever exercise of “ Nature’s cunning”’ dees this work on our present sea-bottom, was adequate to do it in the Laurentian period. The explanation which I suggested, that it is due to a process of chemical “ substitution” (the progres- sive decomposition of the sarcode-body producing a precipita- tion of silicates from sea-water, which replace the sarcode, particle by particle), however “ unscientific’ in the eyes of Professors King and Rowney, has approved itself to Chemical and Paleontological authorities of considerably higher stand- ing than the Galway Professors, as the only one by which the silicification of fossil wood, and the silicification of the animal substance of recent Corals (described by Dr. Duncan as even now going on), can be accounted for. On the other hand, Professors King and Rowney, to whom I sent, about three years ago, an exquisite little internal cast (in glauco- nite ?) of Polystomella, from Captain Spratt’s dredgings in the /Egean, with a request that they would give me their opinion of the process by which it was produced, replied that they considered it to be composed of mud; and though I have re- cently invited them to reconsider this opinion, they have not in any way qualified it. Now let these casts, for the sake of argument, be pie ay to have been formed by the infiltration of mud, then a like infiltration would equally account for the production of the deposit in the chambers, canal-system, and nummuline tubules of Hozoon, which is precisely paralleled by that of many fossil and existing Foraminifera in regard to its mineral condition—as my specimens show.
My contention is, therefore, that the hypothesis of the Fora- miniferal origin of Eozoon canadense entirely accords with the features alike of the general and of the minute structure of
470 Dr. W. B. Carpenter on Eozoon canadense.
the best-preserved specimens of this body, and that it is the only hypothesis which fits all the facts of the case; whilst the hypothesis of subsequent metamorphic change, which has every probability to recommend it, fully accounts for all the appear- ances on which the Anti-Hozoonists rely as evidence of its Mineral origin, which, in the face of the new evidence I have now adduced, is to my own mind utterly “ unthinkable.” I do not attempt, however, by dint of hammering-in, to impose my own (doubtless) prejudiced conclusion upon the minds of others, but have endeavoured to place before them the facts of the case in such a form as may help them to form their own judgment in regard to them.
Until these facts shall have been disproved by the examina- tion of the specimens which I am ready to submit to any or all of my opponents, I must claim to withdraw from a con- troversy which cannot be carried further to any advantage without a “ comparison of actual specimens.” For whilst I admit to the full every evidence of Mineralization adduced by Professors King and Rowney, neither they nor Mr. Carter admit the evidence of Organic structure which they have not seen, but which I have expressed my willingness to place before them, with the parallelisms presented by recent Fora- minifera.
I am endeayouring to engage my Canadian associates in the preparation of a joint Monograph on Hozoon canadense, to be offered to the Paleontographical Society—with a request that before determining either to accept or to decline it, the Coun- cil will appoint a Committee of “ experts,” qualified by their knowledge of Micro-Paleontology and Micro-Mineralogy to judge whether what we hold to be Organic structure can be possibly regarded as the product of any kind of Physical or Chemical action.

Observations on the Spermatophores of the Decapod Crustacea. By M. Broccut.
In 1842 M. Milne-Edwards published, in the ‘Annales des Sciences Naturelles’ (2° série, tome xviii. p. 331), a memoir on the singular bodies met with in the Cephalopoda, and noticed by Cuvier under the name of machines or animalcules de Needham. He demonstrated the true nature of these bodies, showing that they were peculiar re- ceptacles destined to contain the seminal fluid, and he gave them the name of spermatophores.
These spermatophores have since been indicated in several Inver- tebrata. They have been met with, Ist, in insects, M. Lespés having described this mode of fecundation in the cricket; 2nd, in certain worms, such as Clepsine and Nephelis ; and, 3rd, in some of thelower Crustacea, spermatophores having been seen and figured by Jurine and Miiller in Cyclops Castor (Diaptomus Castor). However, the true nature of these bodies was only determined by M. von Siebold. Si- milar receptacles have been observed in others of the lower Crustacea ; but, as far as I know, they have never been indicated among the Decapods.
Now, in investigating the anatomy of some Macrura, I have found very distinct tubes in the interior of the penis of the males. The existence of these seemed to be in relation with the state of func- tional activity of the male genital organs, and to coincide solely with the period of fecundation.
I now believe that I am justified in regarding these tubes as true spermatophores. In fact, in dissecting some male lobsters, I have lately found, in the interior of the penis in these animals, a perfectly distinct tube capable of isolation from the walls of the organ. This tube was situated in the subterminal part of the penis and was of a yellowish-white colour. On placing it under the microscope I di- stinguished in it clearly a structureless envelope and contents formed by spermatic corpuscles. The latter were very distinct, perfectly recognizable, and in all respects conformable to the figures given by M. Kolhker. Here, therefore, we have in a Decapod a tube containing spermatic corpuscles—that is to say, a true spermatophore.
In his ‘Lecons sur l’ Anatomie et la Physiologie comparée,’ M. Milne- Edwards noticed the existence of a rolled-up tube in the penis of the spiny lobster (Palinurus). “ In the spiny lobster,” he says (tome ix, p. 255), “‘ the subterminal portion of the ejaculatory canal is much dilated, and contains in its interior a tube very much twisted upon itself.” Nevertheless the learned Professor does not pronounce an opinion as to the nature of this tube. I may add that M. Alphonse Milne-Edwards was unable to detect the presence of spermatic cor- puscles in it. It seems to me that this tube is very probably of the same nature as that observed in the lobster. I must remark also that M. Milne-Edwards had, as it were, foreseen the existence of spermatophores in the higher Crustacea. Thus, in the work which I have already quoted (tome ix. p. 258), he says :—‘ While investi- gating the Crustacea of the coast of Brittany in 1827, I found a
472 Miscellaneous.
female Cancer pagurus which had copulated a little while before, and bore, buried in each of its copulatory pouches, a white, cylindrical, soft body, which appeared to me to be the terminal portion of the mem- branous penis of the male separated from the rest of the sexual organs of the latter. I regret that I have not had the opportunity of repeating this observation, since my attention has been directed to the spermatophores ; for it is possible that the sort of stopper in question left in the vulva may have been a body of that nature rather than a fragment of a penis.”
In dissecting a female Maia sqyuinado, I found in its copulatory pouches bodies analogous to those indicated by M. Milne-Edwards. The histological examination of these bodies proved that they could not be regarded as fragments of a penis. In fact they showed no trace of organized tissues. It is therefore possible that they must be regarded as remains of the spermatophores of the male. However, as I have not hitherto had the opportunity of observing spermato- phores in the Brachyurous Crustacea, I shall not venture to speak decidedly upon this point.—Comptes Rendus, March 23, 1874, p. 850.
On the Felis euptilura from Shanghai, in the British Museum. By Dr. J. E. Gray, F.R.S. &e.
The British Museum has received from Mr. Webb, through John Russell Reeves, Esq., a wild cat from Shanghai. It has the colour and much of the spotting of the Felis rubiginosa from Western India ; but it is quite different from that long-headed, long-tailed cat in being a short-headed, short-tailed animal, and in the short skull having the incomplete orbits of the true cats, instead of being long and with the complete orbits of Viverriceps rubiginosa.
This cat has all the characters of the smaller spotted Asiatic cats with short spotted tails, on which I published a paper in the ‘ Annals’ for January 1874 (xiil. p. 55).
I am inclined to regard it as a perfect specimen of the Felis eupti- lura, described by Mr. Elliot and figured by Mr. Wolf, P. Z. 8. 1871, p- 761, t. Ixxvi., from a very bad skin, now in the British Museum, supposed to have come from Siberia.
The possession of a perfect skin and skull of this confirms it as a distinct species. The specimen in the Museum chiefly differs from Mr. Wollt’s figure in the streaks on the crown and nape not being quite so wide, and in the tail being rather longer and more cylindrical, which is easily explained when we consider the very bad state in which the skin figured by Mr. Wolf was.
The skull has very large, prominent, swollen, compressed bullee to the ears, and a large deep subcireular cavity at the inner side of the hinder part of the flesh-tooth and the small tubercular grinder.
On the Amount of Pressure in the Sap of Plants. By Prof. W. 8. Crarxe, of Amherst.
It only remains to state in a few words the results obtained by the application of mercurial gauges to the sugar-maple, the black birch, and the grape-vine. Observations were made on one or more

gauges several times daily, and occasionally every hour of the day and night, from the Ist of April to the 20th of July.
A gauge was attached to a sugar-maple, March 31st, which was three days after the maximum flow of sap for this species, so that further observations are required earlier in the season to complete the record and determine with certainty the maximum pressure which it exhibits in the spring. Of the record made, the follow- ing facts are specially interesting: first the mercury was subject to constant and singular oscillations, standing usually in the morning below zero, so that there was indicated a powerful suction into the tree, and rising rapidly with the sun until the outward pressure was sufficient to sustain a column of water many feet in height. Thus at 7 a.m., April 21st, there was a suction into the tree suf- ficient to raise a column of water 25:90 feet. As soon as the morning sun began to shine en the tree the mercury suddenly began to rise, so that at 9.15 a.m. the pressure outward was enough to sustain a column of water 18°47 feet high, a change represented by more than 44 feet of water. On the morning of April 22nd the change was still greater, requiring for its representation 47-42 feet of water. These extraordinary fluctuations were not attended by any peculiar state of the weather, and happened twelve days before there were any indications of growth to be detected in the buds. These observations are believed to be quite new, and as yet in- explicable, but will receive further attention another spring.
The maximum pressure of the sap for the season was observed at 10 a.t., April 11th, and was equal to sustaining a column of water 31-73 feet high. This was an excellent sap day, considering the lateness of the season. ‘There was noticed a general corre- spondence between the flow of sap in other maples and the pressure on the gauge.
After April 29th the mercury remained constantly below zero, day and night. During the month of May there was a uniform suction equal to about 8 feet of water; and the unaccountable feature of this fact is, that, though apparently produced by exhala- tion from the expanding leaves, it remained the same, day and night, for several weeks. In June the suction gradually lessened, and finally disappeared, the mercury standing steadily at zero.
On the 20th of April two gauges were attached to a large black birch—one at the ground, and the other 30 feet higher. The next morning at six o’clock the lower gauge indicated the astonishing pressure of 56°65 feet of water, and the upper one of 26-74 fect. The difference between the indications of the two gauges was thus 29-91 feet, while the actual distance between them was 30°20 feet, so that it corresponded almost exactly as if they were connected by a tube. In order to learn whether the same principle would prevail if the upper gauge was moved, it was raised 12 feet higher. The same correspondence continued through nearly all the observations of the season, notwithstanding the gauges were sepa- rated by 42°20 feet of close-grained birch-wood.
At 12.30 p.m., April 21st, a hole was bored into the tree on the side opposite to the lower gauge, and at the same level. Both

gauges at once began to show diminished pressure, while sap issued freely from the orifice. In fifteen minutes, one pound of sap haying escaped, it was found that both gauges had fallen equal to 19-27 teet of water. Upon elosing the hole the gauges rose in ten minutes to their previous level, showing that the rootlets had reabsorbed in that brief period the sap which had escaped from the tree, not- withstanding the enormous pressure already existing.
A stopcoek haying been inserted into the hole opposite the lower gauge, it was found that the communication between it and the two gauges was almost instantaneous, which appears to prove that the tree was entirely filled with sap, exerting its pressure in all directions as freely as if standing in a eylindrical vessel more than 60 feet in height, as indicated by the lower gauge. The sap-pressure continued to increase until, on the 11th day of May, it represented a column of water 84-77 feet in height, which is believed to be the highest pressure of vegetable sap ever recorded.
The buds of the birch now began to expand, the pressure of the sap to diminish, and the oscillations of the mereury to become more decided and regular than before. The upper gauge ceased to vary May 14th, remaining stationary at zero. The lower one declined slowly and varied greatly, but did not fall below zero until May 18th. On May 27th it also became stationary at zero. The suction mani- fested by the birch was very little, never exceeding 9 feet of water, and continued only for a few days.
To determine, if possible, whether any other force than the vital action of the roots was necessary to produee the extraordinary phenomena described, a gauge was attached to the root of a black birch tree, as follows. The tree stood in moist ground at the foot of the south slope of a ravine, in such a situation that the earth around it was shaded by the overhanging bank from the sun; a root was then followed from the trunk to the distance of 10 feet, where it was carefully cut off 1 foot below the surface, and a piece removed from between the cut and the tree; the end of the root thus entirely detached from the tree, and lying in a horizontal position at the depth of 1 foot, in the cold damp earth, unreached by the sunshine, and for the most part unaffected by the temperature of the atmosphere, measured about 1 inch in diameter: to this was carefully adjusted a mercurial gauge, April 26th. The pressure at once became evident, and rose constantly with very slight fluctua- tions, until at noon on the 30th of April it had attained the unequalled height of 85°80 feet of water. This wonderful result showed that the absorbing-power of living birch-rootlets, without the aid of any of the numerous helps imposed upon them by ingenious philosophers, such as exhalation, eapillarity, oscillation, dilatation, contraction, &c., was quite sufficient to account for the most essential of the curious phenomena connected with the cireu- lation of sap. Unfortunately, in an attempt to increase the capacity of the gauge, the bark of the root was injured, and this most in- teresting experiment terminated. There can be little doubt that future trials, carefully conducted with suitable apparatus, will achieve even more marvellous results.
Miscellaneous. 475
The original experiment of applying a mercurial gauge to the grape-vine, first tried by the Rev. Stephen Hales, of England, one hundred and fifty years ago, was repeated May 9th, and a pressure of 49°52 feet of water obtained May 24th. This is 64 feet higher than was observed by Hales. The peculiar features of the pressure of the vine-sap are :—its lateness in the season; its apparent inde- pendence of the weather; its uniform and moderate rise, day and night, to its maximum; its very gradual decline to zero without any marked oscillations ; and its constant and almost unvarying suction of from 4-5 to 6-5 feet of water, manifested from June 20th to July 20th, when the observations ceased.—/rom the Eleventh Annual Rzport of the Massachusetts Agricultural College, January 1874.
The Bogota Cat (Felis pardinoides, Gray). By Dr. J. E. Gray, F.R.S. &c.
In the ‘ Annals’ for 1874, xiii. p. 51, I gave the reasons for differing from Mr. Elliot’s opinion that the cat I named Felis pardinoides in the British Museum, received from the Zoological Society as coming from India, was the same as Felis Geoffroyi. At the same time I observed, ‘“‘ the Indian habitat has not been confirmed ; and the species has a very South-American aspect.”
The British Museum has received, from Mr. Edward Gerrard, a cat from Bogota that I have no doubt is the same species as the typical specimen of Felis pardinoides ; but it differs from it in being a nearly adult specimen, as is proved by the examination of the skull; and it has a more fulvous tint, and the fur is softer; but this may only depend upon the age and season in which it was killed.
This species of South-American spotted cat has the small head and much the character of Felis macroura; but the tail is rather taper- ing and not so long; instead of having the few broad black rings of that species, it has a larger number of narrow black rings, which are interrupted on the lower side, and these rings on the hinder half of the tail are broader and more distinct than those of the basal half. The spots on the body are much more numerous ; and those on the hinder parts of the sides are pale, surrounded behind with an imperfect ring of small black spots.
The Habitat of Pelargopsis gigantea.
To the Editors of the Annals and Magazine of Natural History.
21 Opernring, 4. Stock, Vienna, 23/5/74.
Dear Strs,—In the note on the “ Habitat of Pelargopsis gigantea” in your Journal (May 1874), line 6 of the text, is a misprint in the fifth word. It must be “ Joldé,” and not “ Told.”
You will oblige me by rectifying this in your next number, as this misprint is disagreeable in a note wherein I correct the statement of another. Yours very truly,
