Smita Woopwarp, LL.D., F.R.S., of the British Museum. [Plate I.] Tue Jurassic Vertebrate fauna of the Australian region is still almost unknown, some Ganoid fishes * and, perhaps, a few small Dinosaurian bones f being the only fossils repre- senting it hitherto described. A tooth of Ceratodus and a Dinosaurian claw discovered by Mr. W. H. Ferguson in the Lower Jurassic cliffs of Cape Patterson on the south coast of Victoria are thus of special interest. I am indebted to Prof. J. W. Gregory, F.R.S., for the opportunity of studying these specimens. * A.S. Woodward, “ The Fossil Fishes of the Talbragar Beds,” Mem. Geol. Surv. N.S. Wales, Palzont. no. 9 (1895); T. S. Hall, “A new Genus and a new Species of Fish from the Mesozoic Rocks of Victoria,” Proc. Roy. Soe. Vict. n. s. vol. xii. (1900) art. xvi. + H. G. Seeley, “On Agrosaurus Macgillivrayi (Seeley), a Saurischian Reptile from the N.E. Coast of Australia,” Quart. Journ. Geol. Soe. yol, xlvii. (1891) pp. 164-165, with figs. Ann. & Mag. N. Hist. Ser. 7. Vol. xviii. 1 2 Dr. A. 8. Woodward on a Tooth of Ceratodus The tooth of Ceratodus (P1. I. fig. 1) is firmly fixed to a recognizable piece of the splenial bone, and is therefore proved to belong to the left side of the lower jaw. It unfor- tunately lacks the foremost denticle, but clearly agrees with the majority of the Mesozoic teeth of Ceratodus in possessing only four denticles altogether. It is thick and robust, with the grinding-surface slightly convex, but wavy, and marked by a very prominent coarse network of ridges (fig. 1). It is specially remarkable for the long and narrow shape of its crown, which is bounded on the inner side by a nearly straight margin, not angulated opposite the second or third denticle. So far as can be determined from a fragment, the foremost denticle of the tooth appears to have been relatively large, while the others rapidly decrease in size backwards. The second and third denticles are sharply compressed to an acute outer edge, and are separated by deep notches at the outer margin (fig. 1 a), though not continued as conspicuous ridges on the crown. ‘Lheir long axes are not oblique, but directed nearly at right angles to the inner margin. ‘The fourth or hindmost denticle is comparatively blunt. Fine horizontal lines of growth are seen on the flattened inner (fig. 1b) and outer faces of the tooth. The specimen thus described differs from all the known Mesozoic teeth of Ceratodus in its narrowness, combined with the straightness of its inner margin and the direction of its second and third denticles. In these respects, it is interesting to observe, the tooth more nearly approaches that of the existing Ceratodus or Neoceratodus ot Queensland (fig. 2), and its only striking difference from the latter consists in its having four denticles instead of six. The multiplication of the denticles has already been observed in the teeth of certain sharks as they are traced onwards in time*; the same phenomenon obviously occurs in Ceratodus. There is, therefore, no doubt that the tooth from Cape Patterson represents a new species, which may be named ~ Ceratodus avus. The fossil proves for the first time that the remarkable Dipnoan genus to which it belongs had already reached the Australian region so long ago as the early part of the Jurassic period. At that epoch Ceratodus was still living both in Europe f and in North America f, while it survived * A,S. Woodward, “On the Paleontology of the Selachian Genus Notidanus, Cuvier,” Geol. Mag. [8] vol. iii, (1886) p. 257. + Ceratodus Phillipsi, Agassiz, ‘ Rech. Poiss. Foss.’ vol. iii. (183° ». 135, pl. xix. fig. 17; A.S. Woodward, Proc. Geol. Assoc. vol.

In the same rock as that from which the tooth of Ceratodus was obtained at Cape Patterson Mr. Ferguson found the terminal phalangeal bone shown in fig. 3. Among Jurassic fossils this specimen can only be compared with the claw of a carnivorous Dinosaur, and there is little doubt that it represents a genus more or less related to Megalosaurus +. The bone has decayed somewhat in the upper part of its proximal end, but is otherwise well preserved and displays its principal characters, The phalangeal is laterally com- pressed, so that its greatest transverse diameter is somewhat Jess than its original depth at the proximal end. The distal tapering half of the bone is only gently curved downwards, but at the same time bends slightly to the left side. The distal half of the lateral face is marked with the usual deep longitudinal groove connected with the fixing and nourishment of the horny claw which originally ensheathed the bone. The proximal end (fig. 3a) is divided, as usual, by a median vertical ridge into two facettes, which are nearly flat. For comparison with this specimen one of the finest known Megalosaurian claws from the English Wealden is shown in fig. 4. The latter is shorter and stouter than the former, and its deep lateral groove extends further backwards; but the general resemblance between the two fossils is very striking. It is to be hoped that further diligent search may be made at Cape Patterson to recover the Vertebrate fauna indicated by these fragmentary fossils. ‘The discovery of the terrestrial and freshwater life of the Australian region during the Jurassic period would supply a most important deficiency in paleontological knowledge.

I].—Notes on Irish Hydrachnida ; with Descriptions of a new Genus and Two new Species. By J. N. HAvBERT. [Plate II.] THE following paper contains records of some species of new or rare Hydrachnida selected from a large amount of material found in various localities in Ireland during the last five years. Of these species two appear not to have been previously described ; one of them proves to be the type of a new genus, while of the remaining species eight are here recorded for the first time from the Britannic * area. It was originally intended to reserve the new mites for description in a general list of the Irish Hydrachnid fauna which is being prepared. Before such a list can be com- pleted, however, it is necessary to carry out some further collecting in certain parts of the country, and it seems more satisfactory to record the new species without further delay. The most interesting of the new mites is one of which [ was fortunate enough to find fully developed specimens when collecting last May in the south-west of Ireland. The species in question seems to bean extremely isolated form, possessing a combination of characters which at once distinguish it from any of the known genera. It would be easy to briefly define a new genus for the reception of this mite by referring to the structure of a very few organs, such as the palps, legs, Ke. ; in a group like the Hydrachnida, however, where there is such a great variety of structural detail, it seems especially necessary to rely on a combination of various characters in the formation of new genera. JI have to acknowledge the assistance of the Irish Fauna and Flora Committee supported by the Royal Society, and also of the same Committee when acting under the auspices of the Royal Irish Academy: several grants enabled me to collect in distant parts of the country. The nomenclature used in the following list is that of the ‘Tierreich’? (“ Hydrachnide und Halacaride,” Piersig and Lohmann, Lieferung 13, 1901). * The use of the word Britannic instead of British for faunistic purposes has been proposed by Professor G. H. Carpenter, as the latter term is now so frequently used to distinguish records referring to Great Britain alone (‘ Irish Naturalist,’ vol. xv. p. 15). Mr. J. N. Halbert on Lrish Hydrachnida, 5 MOoMOoNIA%, gen. nov. Diagnosis of Genus.—An Hydrachnid of the family Hygro- batide (Kramer, Wolcott, &c.), with a highly chitinized integument modified into chitinous plates. In shape re- sembling the genus J/dea, with a convex dorsal area separated from a larger ventral field by a groove in which are a number of paired gland-openings. Epimeral groups close together, occupying most of the underside of the body. Genital area situated between the fourth epimera, flanked on each side by a triangular plate, in which are imbedded three genital suckers of the Sygrobates type. Palps with the penultimate segment angularly swollen on the ventral surface and armed with two stout chitinous teeth; fifth segment ending in an exceedingly fine point. [First pair of legs modified, the terminal segment deeply excavated on its upper margin, with a broad-shanked bifid claw articulating deeply in the segment, and, in the type species, with a terminal membrane. The three posterior pairs of legs are provided with swimming-hairs. It will be seen from this short diagnosis that the genus Momonia possesses a very anomalous combination of characters which renders the placing of it in a satisfactory position in the Hydrachnid series a matter of some difficulty. On the whole, however, it shows affinities with the genera J/idea, Mideopsis, &c., and it seems to me that it should be placed in an intermediate position between these genera and the HHygrobates group. Momonia falcipalpis fF, sp. n. (Pl. II. figs. 1-4.) Male.—Body slightly longer than broad, evenly rounded posteriorly, and narrowed towards the front margin, where there are two hair-papille. Seen from the side the dorsal outline is moderately convex and the ventral surface flat over the epimeral area; thickness of the body dorso-ventrally about three fifths of the total length. IJntegument highly chitinized, with a dorsal groove running round close to the body-margin; in this groove are placed at least six pairs of * Momonia, or Mumonia, the ancient Latin name of the province of Munster. This name has also been used by Mr. R. Lloyd Praeger, M.R.1.A., to indicate the group of plants with a southern range in Ireland (see ‘ Proceed. Royal Irish Academy,’ vol. xxiv. 1902-1904). + The specific name is suggested by the shape of the terminal palp- segment, 6 Mr. J. N. Halbert on Irish Hydrachnida. chitinous hair-bearing glands. The greater part of the dorsal area is covered by a large shield with sinuous side-margins bounded by the dorsal groove, the rounded posterior margin reaching to the end of the body. This plate is wrinkled longitudinally, and under a high magnification it is seen to have a finely shagreened appearance as well as polygonal reticulations. In front of this large shield lies a short broad plate, emarginate anteriorly, and rather less than half the breadth of the dorsal shield. The dark-pigmented eyes, separated by an interval of about 176 yp, are situated close to the front margin of the body. On the inner side of each eye- group stands a conspicuous hair-papilla. The greater part of the ventral side is occupied by the epimeral plates ; the first and second epimera are of the usual shape—except that the first epimeron is very narrow and tapers inwardly into a rather fine point—separated by an extremely narrow interval from the third epimera. The last are quadrilateral in outline, with the front and hinder margins sloping downwards. The fourth epimeron is extremely large and characteristic ; the inner margin is continued for a short distance in a line with that of the third epimeron, it then bends suddenly outwards and downwards in a sinuous line to near the hinder margin of the body, fusing with the chitinous. integument of the sides of the body. Near the middle of the fourth epimeral area on each side is a group of long hairs. The epimera are all finely shagreened and reticulated in the same way as the dorsal shield. The genital area lies in the anterior space between the fourth epimera ; it is flanked on each side by a long triangular plate, which carries three genital suckers, placed one behind the other, similar in structure to those found in Hygrobates and allied genera. A transverse chitinous plate, in which is imbedded the anal opening, occupies the remaining inter- epimeral space. The capitulum is rather small, projecting downwards for part of its length beyond the ventral outline of the body; maxillary shield measuring about 110 mw in length (not in- cluding subcutaneous process) and 77 w in breadth. The palps are small, the five segments measured along their dorsal margins are 30 pw, 75 w, 50 w, 85 w, 55 w respec- tively ; segments 1, 2, and 3 may be compared with those of Mideopsis ; 2 and 3 are furnished with a number of rather stout hairs on the dorsal surface; 4 is the longest palp- segment, it is slightly convex dorsally, with two long fine hairs, ventral surface produced beyond the middle into a well- marked angular prominence, on which are two short stout Mr. J. N. Halbert on Lrish Hydrachnida. r teeth placed close to the inner side of the segment; 5 is nearly as broad at base as the distal margin of 4, tapering gradually into a long sharp point; the upper and lower surfaces are each armed with a long hair and a sharp spine; on the outer side close to the base is another spine. First pair of legs (length about 814 «) modified, without swimming-cilia, slightly longer than the body, the segments gradually increasing in length from 1 to 5. Segment 1 very short, 2 and 3 straight, with a number of long bristles; 4 curved, with the ventral distal margin notched ; 5 straight (length 260 «), broader than preceding segments, and nar- rowing towards the distal extremity, on which are seven or eight long hairs. Segment 6 (fig. 3) articulates with a conical projection on the penultimate segment, short, with convex sides, very deeply hollowed out on its upper distal margin ; a powerful claw-like structure with a broad shank and sharply bent bifid extremity articulates with the inner part of the excavation ; a few long hairs and a peculiar cone- shaped membrane project from the extremity of the segment. The last three pairs of legs do not present any remarkable characters ; they increase in length from before backwards and are provided with long swimming-cilia; the terminal segments are armed with two recurved tridentate claws resembling those of Brachypoda. During life the colour was a pale yellowish green, marked on the dorsal surface with reddish brown; Malpighian area yellow, indicated anteriorly by four lobes arranged across the body. Measurements.

N. Halbert on Irish Hydrachnida. Arrhenurus octagonus, sp.n. (PI. I. fig. 5.) Male.—Colour during life red, with ill-defined darker markings on the back. In dorsal view the body is roughly octagonal in shape, the posterior half being somewhat similar in outline to the anterior. Front margin almost straight, about equal to half the width of the body ; all other margins very slightly emarginate, There are no conspicuous dorsal humps, but in the middle of the posterior margin there is a deep excavation, with a prominence on each side on which is a long hair. Dorsal furrow roughly circular in form, enclosing a comparatively small area (length 537 y) of the middle of the back. The appendage is short, measuring about a sixth of the entire length of the animal and about four fifths as broad; in dorsal view mostly covered by the hinder part of the main body ; sides of the appendage hardly constricted at base, gradually narrowing inwards and blending with the hinder margin. Posterior dorsal margin with a wide excavation reaching from side to side; posterior ventral margin slightly sinuate, pierced in the middle by a narrow deep indentation, which widens noticeably at its deepest part and reaches the base of the appendage. The pettolus is composed of two finely pointed pieces, which are closely approximated in the — living mite, and project in the middle line very slightly beyond the margin of the appendage. There are five or six pairs of very short hairs on the end of the body. Genital plates large, sinuate anteriorly, and gradually narrowing towards the sides of the body, which they do not overreach, pimeral plates remarkably long and narrow, rather closely resembling those of A. s¢nuator, Miiller. Palps stoutly built, with prominent distal angles to the segments. ‘The inner surface of the second segment seems to be without a hair-pad, but carries a few stout unfeathered bristles. Fourth segment with a long straight spine near the inner distal corner and a widely forked tactile hair on the apical margin. The legs do not present any unusual characters ; they are rather stout, of moderate length, and the fourth segment of the last pair is without a spur. Measurements.

Type specimen deposited in the Dublin Natural History Museum (register no. 180, 1906). Arrhenurus Leuckartt, Piersig. Both sexes of this mite were collected in the same locality as the preceding species by Mr. Beresford. It is apparently one of our rarest Arrhenur?, these being the only Irish specimens that I have seen. Dr. George includes it in his Lincolnshire list, and Mr. Soar reports it from the Norfolk Broads. Arrhenurus Neumant, Piersig. This is another addition to the list of Irish Arrhenuri published a few years ago*. I found several specimens (g and ¢) last year in Looscaunagh Lough in May, and also in Glendalough Lake, Connemara, in the following autumn. Mr. W. Williamson has taken it in Scotland (Trans, Edinb, Field-Nat. and Micros. Soc. Session 1905- 1906). Arrhenurus Stecki, Koenike. 1894, “ Zur Hydrachniden-Synonymie,” Zool. Anz. xvii. p. 274, fig. 5. A male of this rare species occurred in a bog-pool almost filled with Sphagnum near Ross, Co. Galway, in September 1905. ‘This is the smallest species of the genus as yet found in Ireland, my specimen measuring but 572 mw in length. The colour was pale yellow, with two black blotches showing through behind the epimera. Localities—Up to the present time this species has been recorded from Switzerland, where it was found in a similar kind of locality (Moosseedorf-See bei Bern), Germany, and Norway (1899). Dr. George has recorded it from Lincoln- shire (‘ The Naturalist,’ 1905, p. 25). Medeopsis crassipes, Soar. 1904. “Two new British Water-Mites,” Journ, Quekett Micros, Club, p. 107, fig. 2.

Halbert on Irish Hydrachnida. as September 1899, in Upper Lough Erne, Co. Fermanagh. The specimens were mixed with the commoner J/ideopsis orbicularis and were so overlooked, I have since taken the species in Lough Gill, Co. Sligo. * Sperchon brevirostris, Koenike. 1895, “ Neue Sperchon-Arten aus der Schweiz,’ Rey. Suisse Zool. iii. p. 416, pl. xii. figs, 1-2.

Fortunately the single specimen taken is a male and shows the characteristic modification of the fourth pair of legs, as described and figured by Dr. Thor. This appears to be the first record of the species since the original record from Norway, and it seems to have been omitted from the volume of the ‘ Tierreich’ (1901) treating of the Hydrachnida, * Species marked with an asterisk are recorded for the first time from the Britannic area, Mr. J.

Naturvid. xxxviii. pp. 875-878, pl. xvii. figs. 21-24. This species is allied to P. nodata, Miller, and P. contro- versiosa, Piersig, but differs sufficiently from both in the structure of the genital area, palps, and especially in the armature of the terminal segment of the third pair of legs in the male. The species was first described in 1896 by Dr. Thor, and was supposed by Dr. Piersig to be synonymous with P. controversiosa, but the more detailed description published in the above reference clearly shows the distinctions between the species. The only Irish specimens examined were taken by Mr. W. F. de Vismes Kane in Drumreaske Lake, Co. Monaghan. *Panisus Michaeli, Koen. (PI. II. fig. 6.) 1896. Zool. Anzeiger, xix. p. 356, When in the west of Ireland in the spring of 1901 I found an Hydrachnid of the genus Panisus amongst water- plants in a small stream which flows into the sea at the head of Ballysadare Bay. On examination it agreed closely with the description of P. Michaeli, Koenike, except that the chitinous marginal piates of the dorsal surface numbered four on each side in my specimen, instead of five, as recorded for P. Michaeli. Onsending drawings of the mite to Dr. Koenike, he was good enough to assure me that my species is identical with P. Michaeli. ‘There are in reality only four marginal plates on each side in that species; the statement that there 12 Mr. J. N. Halbert on Trish Hydrachnida. were five was due to the outlines of the plates not being clearly visible at the time the preliminary description was made. There are sixteen chitinous plates on the dorsal surface, arranged as follows :—A middle series, consisting of a large plate between the eyes; behind this are three small circular plates, arranged on each side of the middle line; and, finally, a large terminal plate, sinuate in front, with the postero-lateral corners produced into pointed processes. The eight marginal plates are arranged in a line on each side of the body ; the most anterior of these sends forward a long narrow prolongation on the outside of the eye. All of the dorsal plates are coarsely areolated towards their margins and more finely in the centres; they are also very irregular in outline, differing considerably on each side of the body. The species seems to be very local, and as I have seen no reference to figures, a drawing (fig. 6) of the dorsal surface is given; the areolation of only the terminal plate is indicated. Localities—Panisus Michaeli was first recorded from Switzerland, where it was discovered by Dr. A. D. Michael at Davos; and Dr. Sig. Thor has recently recorded it from Norway. I have also seen a specimen collected by Mr. William Evans near Bolerno, Scotland, in the autumn of last year, Thyas longtrostris, Piersig. This very distinct species is of local occurrence in Ireland. I once found amongst Callitriche ina small pool near Ken- mare many specimens, some of which were very large, measuring nearly 3 mm. in length. In his paper on the British species of Thyas (‘Science Gossip,’ viii. p. 46) Dr. George refers to the occurrence of this species in Ireland, and Mr. C. D. Soar has since found it in the Norfolk Broads. EXPLANATION OF PLATE II. Fig. 1. Momonia faleipalpis, sp. n. Dorsal view; legs and palp not drawn. xX 60. Fig. 2. Momonia faleipalpis, sp.n.

(2) i. p. 184, 1832), gave as the type his A. fuscata from New Guinea. © This genus is therefore structurally distinct from other species included subsequently in Aphena=Aphana, Burm., and Penthicodes thus becomes available. Blanchard regarded the name Aphana as preoccupied by Aphanus, Lap., an argument I did not and do not follow ; but the type of Guérin’s Aphena settles the question. Genus SCAMANDRA.

IX.—Alternation of Generations, Metamorphosis, and Direct Development. By W. WEDEKIND*. In my previous writings on the subject of parthenogenesis I have already pointed out that, in my opinion, so-called asexual reproduction was everywhere the primitive method, and that it is only in the course of phyletic development, through the series—segment, bud, spore, and female and male partheno- ovum,—that at last the ovum needing fertilization and the sperm belonging to it have arisen therefrom. It follows, therefore, that all organisms with sexual reproduction must be derived from asexual ancestors. According to the bio- genetic law of recapitulation this phylogeny must also very generally have been repeated in the ontogeny, and I would, moreover, venture to assume that in earlier epochs the course of the entire ontogeny was not yet by any means so rapid as it usually is to-day. It therefore follows from our theory that the ancestral stage of asexual reproduction must formerly have still been displayed in the development of each indi- vidual, and that it was only gradually that it became more and more suppressed, According to this interpretation, then, in the first instance from every fertilized ovum at least an asexual generation must again have developed, and only from this has there arisen once more the ultimate form with sexual reproduction. * Translated by E. E. Austen from the ‘Zoologischer Anzeiger,’ Ld, xxix. Nos. 25/26 (March 6, 1906), pp. 790-795, Generations, Metamorphosis, Le. 39 In other words, alternation of generations was universally the most primitive form of ontogeny, and consequently it 1s not of merely secondary origin through selection, but, on the contrary, it has persisted only here and there. ‘I'hus, on thie basis of the theory of descent and the biogenetic law of re- capitulation we arrive at this simple explanation: — alternation of generations is (nothing more than) the ontogenetic repetition of the phylogenetic progressive developnent from lower organisms with asexual reproduction into higher species with dissociated sexual products. In this way, too, the different varieties (heterogony &c.) are easily intelligible. When, in consequence of continued acceleration of the ontogeny, the first asexual generation produces, instead of the previous numerous progeny, only a single offspring, and when, moreover, this single descendant no longer severs itselt from the mother, but proceeds from it more or less con- tinuously, the ontogeny assumes the form of metamorphosis. The latter has therefore arisen from alternation of generations by a process of constant abridgement; and thus we can shortly define metamorphosis as a curtailed alternation of generations. In all cases, then, it is only through continuous acceleration of the ontogeny that direct development, as we find it to-day, has arisen from alternation of generations and metamorpliosis. Direct development is everywhere the secondary process, which in consequence of its great rapidity is also well-nigh incomprehensible, whereas it is much easier for us to picture to ourselves phylogeny, which is a million times slower, and also an earlier and less rapid ontogeny. In this way, therefore, alternation of generations and metamorphosis lose all that was previously inexplicable and become easily intelligible to us by means of the theory of descent, when we regard them simply as ontogenetic recapitu- lations of the development of the species. They are no new processes, which have only arisen at a later date, but, on the contrary, the oldest forms of ontogeny, which, on a further development of the organic world, should it chance to occur later on, will tend towards direct development, but have not originated from the latter. ‘heir occurrence to-day represents only tie last remnants of earlier and probably much more widely diffused conditions, just as is the case as regards modern parthenogenesis. A material advantage of this mode of interpretation, there- fore, is that it is nowhere necessary for us to assume the existence of a cwnogenesis, with retarded and altered develop- ment. Ontogeny consequently makes no detours, but merely 40 Mr. W. Wedekind on Alternation of goes on developing continually in a tachygenesis which becomes constantly more and more accelerated. Moreover, up to the present it has nowhere been shown that the retardation of ontogeny is only secondary. Fritz Miiller, too, who is much quoted to this end, certainly brings forward in his well-known memoir many an instance of tachygenesis, and also maintains that development is frequently falsified by the struggle for existence which tlie free-living larvee had to undergo; he remarks that this point needs no further elucidation, since it is self-evident, &c., Kc. The author in question states that it is easy to understand how even a direct course of development may again be trans- formed through the struggle for existence into a development with metamorphosis. But in no passage of his work does Miiller adduce any fact whatever in favour of this assertion, any more than the point has previously been proved by other authors. ‘To me, too, that nature in so many instances should have made such a retrograde step is anything but “ self- evident” and ‘easy to understand”; and still less can I picture to myself the znner causes of such a process, especially since I have long ago abandoned the pious belief of my scientific childhood in the omnipotence of selection. The “utility”? also of such a retarded development is absolutely incomprehensible tome. Forwhat have butterflies, - for instance, to gain from the fact that, with a more protracted caterpillar life, they are so much the longer exposed to the danger of being devoured before they reach the final goal of their development? Or wherein are they benefited by previously as caterpillars eating up the very plants upon which they subsequently want to live as butterflies ? And so probably in all cases the harmfulness of a slow development can be demonstrated at least equally as well as the advantage ; and even when the latter is really present, it still need not on that account be an originating cause, but is, as I interpret it, merely the external stimulus, which, in the case of the species in question, has led to the longer ontogeny persisting until the present day. In almost every instance, however, a species must derive the greatest advantage from completing its developmental stage as quickly as possible, in order afterwards to continue to live quite a Jong time as an adult animal. Among insects I need only remind the reader of the highly organized Hymenoptera, of which the metamorphosis 1s no longer so “complete” as is that of the beetles, butterflies and motlis, &e. ‘Lhe metamorphosis, e. g. in the case of the bees, which, in contrast to that exhibited by the other orders referred to, Generations, Metamorphosis, Le. 41 lias already undergone considerable reduction, surely bears witness to the general striving after a constantly shorter tachygeny, although, from internal causes of which we are still ignorant, in the case of many lower animals this has not yet advanced so far as direct development. As the weightiest objection to my interpretation I shall naturally again have to encounter the views on phylogeny which are held to-day. In the case of the lowest orders among the Tunicata we find direct development : consequently the alternation of generations in the higher Tunicata, which are evidently derived from the former, can only be a secondary acquisition, And likewise in the case also of the higher insects, since they are said to be derived from their lower relations which have direct development, “complete” meta- morphosis can only be of secondary origin. In opposition to this line of argument, however, I would call attention to the self-evident truth that in no class of the animal kingdom does there obtain a relation of direct descent between its existing higher and lower orders, and to this rule the Tunicates and Insects form no exceptions. The ancestral form of the Tunicata was consequently not in all points identical with the Appendicularid of the present day, but must at least have had a divergent attribute in common with the higher Tunicates. And thus we may naturally just as well imagine these Archi-Tunicates as in other respects entirely similar to the Appendicularide, but with asexual reproduction. A portion of these, the present Appendicularid, then branched off to one side quite early, and displayed a very rapid and precocious transition to sexuality, so that they, perhaps evey in consequence of this over-speedy advance to sexual life, subsequently remained stationary at a lower stage of the development of the phylum. On the other hand the majority, while retaining asexual reproduction for a longer period, continued perhaps on that account slowly but nevertheless surely to make progress in their phylogenetic development, until in their case also a conclusion was reached with the attainment of sexuality in the higher orders. Moreover, this phylogeny of varying length was subsequently retained in the ontogeny also. Since no otlier material difference any longer existed between the ancestral form with asexual and the present Appendicularide with sexual reproduction, ontogeny, too, was easily able to proceed to direct development, while the less rapid phylogeny of the higher orders has left its traces in their ontogeny even at the present day. Similarly, too, the “typical archi-normal Insect” was, in 42 Mr. W. Wedekind on Alternation of my opinion, (not provided with wings and) not dicecious. This ancestral form must rather have been represented by somewhat worm-like creatures, which (just as, indeed, many worms still do) reproduced themselves asexually and gave rise polyphyletically to the different orders. From these, too, there then very early branched off a portion, which likewise again, precisely because it precociously developed the con- dition of separate sexes, also remained stationary at the lowest stage; while the remainder, again in consequence of longer retention of the asexual mode of reproduction, had time to undergo further phyletic improvement, and only at the con- clusion of their various orthogenies also became parthenogenetic or dicecious as the case may be. Here also the phylozeny of varying length is then reflected again in a reduced or “complete” metamorphosis, while the latter itself represents no more than the “ welding together ” of the two primitive generations, It appears exactly as though the transition to sexual repro- duction is also universally connected with a pause in the orthogeny, so that, if the latter takes place rapidly or prematurely, the whole of the rest of the organization also generally remains stationary at a lower stage, while the slower attainment of sexuality in the phylogeny likewise allows time for a higher orthogeny. ‘Lhe one condition directly entails the other, and I would term this phenomenon shortly the law of precuocity (prematurity). A more rapid ontogeny, a direct development, conscquently only shows that the earliest stages of the asexual ancestors were already abandoned at a very early period, but not that they had been altogether wanting ; and it may also very well be that traces of them are still to be discovered even at the present time. Naturally my theory is not capable of direct proof, any more than is the opposite view. I think, however, that my theory is simpler and more natural, since by means of it, indeed, we at once get rid of the entire cenogeny, and need only imagine the ontogeny as baving been accelerated, but not as having subsequently been altered, by side influences. In this way also we should surely find less difficulty in understanding the manifold transitions, which still frequently occur especially between alternation of generations and meta- morphosis, and with regard to which we may be in much doubt as to whether we are still confronted with a reduced alternation of generations or have before us an already commencing metamorphosis. They are all just gradations of one and the same phenomenon, which pass without a break one into the other, and with which hitherto the majority Generations, Metamorphosis, de. 43 of authors have not known how to deal correctly. Brandes alone, in his new edition of Leuckart's work on ‘ Parasites,’ speaks on one occasion of a “ masked” alternation of genera- tions ; but otherwise such intermediate stages are ‘always interpreted as “commencing” alternation of generations, But still it is by no means quite clear how such a view can be taken. There certainly can be no question of orthogeny, and, on the other hand, neither can any value whatever be attributed to such “ beginnings ” from the point of view of selection. ‘Thus it is consequently in all probability more correct to regard them simply as purposeless remnants, and so to consider them as we do the rudimentary organs, which, indeed, were equally conundrums before Darwin’s time. In the embryological works of the last few years will be found the description of many a phenomenon which from this point of view would be much more readily intelligible. The regenerative faculty, too, is thus perhaps capable of being interpreted simply as the rudiment of an earlier asexual mode of reproduction. The ability to produce from their asexual cell-material anew and distinet individual has gradually been lost by the higher animals (and this is how I account for metamorphosis also) ; but at least they have still retained the power of continually bringing the old individual up to its normal condition. ‘This, then, probably also explains why it is precisely organisms with undiminished asexual reproduc- tion (thus, the plants in an especial degree) that do not regenerate ; and hyper-regeneration, too, is surely easy to understand when we regard it as a more powerful remnant of an earlier asexual reproduction. It may be that thoughts like these, have already occurred to one naiuralist or another, and that it was only Tunicates, Insects, &c., that hitherto have always led to their being abandoned again. On that account I have already dealt with this main objection in the present paper, while I must defer the further development of my theory in fuller detail until somewhat later, in connexion with my thesis on partheno- genesis and arbitrary determination of sex in the higher animals. For it all hangs together, one thing follows from the other, and everything rests upon a mutual basis. The entire development of the organic world is to my mind purely orthogenetic process, consisting in continually ad- vaneing ‘‘sexual dissociation” of the primitively latent- hermaphrodite (so-called asexual) original condition. Without such a “sexuality” of the organic world, a natural force, therefore, which has hitherto been disregarded, we shall, in my opinion, be unable to furnish a complete explanation of 44 Dr. N. Annandale on new Barnacles. organic life; but with a working hypothesis of this kind we at least advance a step or two further. Just as little as we can explain the magneto-electric phenomena by means of mechanics alone, so do we find that these two no longer suffice for the organic phenomena; on the contrary, in their place also we must now assume the existence of a special form of energy, upon which, from its most conspicuous quality, [ bestow the designation “sexuality.” In this force there is, of course, just as little of the super- natural as in the other forces of nature. And that it is likewise already capable of being expressed in figures and is subject to mathematical treatment I shall shortly show elsewhere in a paper on the mathematical equations of the partheno-ova and their fertilization.

Long., ¢ 10°5, 9 12°5 mm. flab, N.E. Sumatra, Indragiri River. A pair of this pretty little insect was found by Mr. Row- land Taylorin 1895. It has the general aspect of Lachnosterna and Brahmina, from which it is impossible to dissociate it in spite of important divergences. Its very short and prominent anterior coxe infringe the primary characteristic of the true Melolonthini, with which the fused abdominal segments and general structure connect it. Its most striking feature is the enormously elongate club of the male, consisting of three equal joints almost as long as the elytra. The scape is about as long as the six joints forming the stipes taken together, these being very short, but slightly increasing in diameter as they approach the club. In the female the club is extremely short, and between it and the elongate first joint there are only five joints, which are not compressed as in the male, but are conjointly a little longer than the scape. The prothorax is finely rugulose, the scutellum smooth and velvety, and the elytra very irregular, with shallow depressions, variolose punctures, and strong carine near the apices. The organs of the mouth are rather peculiar, and the claws have a strong curved tooth about the middle. ‘The legs and underside are everywhere strongly punctured, and there is a greyish bloom partially covering the sterna, abdomen, and elytra.

Andersen on the Bats of the Two species of this genus, both inhabiting Borneo, have previously been described. ‘The present one agrees with them in all its essential characters, but is much larger, and, indeed, is by far the largest of the great Lachnosterna group known to me. In its general form and colour it is like O. princeps, Sharp, but the long erect hairs with which the upper surface bristles distinguish it from all its congeners, now three in number. These hairs arise from very large punctures which are scattered irregularly over the prothorax and front of the head, but upon the elytra are confined to the smooth slightly elevated coste. Another peculiar feature is found in the shape of the prosternal process, which has the unusual form of a transversely placed crescent, the two extremities of which are acutely pointed but not much elevated. A single specimen was found by Mr. Charles Hose. Octoplasia prolix 1, sp. 0. Valde elongata, castanea, capite nigro, femoribus flavis, supra glabra, pectore dense flavo-hirto; capite lato, clypeo leviter bilobato, impunctato, margine reflexo, fronte crebre punctata, lateribus parcissime sed longe hirsutis ; prothorace grosse sat crebre punc- tato, medio paulo impresso, lateribus crenatis, piliferis, regulariter arcuatis, haud angulatis, angulis anticis acutis, posticis rotun- datis; scutello grosse punctato; elytris longissimis, levibus, parum punctatis, costis sat distinctis, fere impunctatis, marginibus | exterioribus haud reflexis; pygidio fortiter crebre punctato; processu prosternale breve, conico. Long. 36 mm.; lat. max. 15 mm. Hab. Borneo, Kina Balu (Whitehead). I have seen only a single specimen of this also. It is another large species, but is chiefly noticeable for its great elongation, the elytra being four times the length of the pro- thorax. They have no silky bloom like O. gigantea, and their puncturation is rather feeble. Their lateral margins are bordered with a rather wide membrane, but are not reflexe |, as in the other species.

The subjoined characterization is confined to the features in which Micronycteris differs from Glyphonycleris :— Skull *.—Facial portion, immediately in front of orbits, not conspicuously inflated. Basioccipital pits, antero- internally to cochlez, shallow. Dentition +.—? not especially modified (compare Glypho- nycteris). Upper canines not shortened, their vertical being about twice their antero-posterior basal diameter. The “heel” of p® represented only by a very narrow cingulum. Inner border of the cingulum of p' with a distinct shallow emargination, dividing the cingulum into an antero-internal (“cusp 6” [) and a postero-internal tubercle (‘cusp 7”). Hars.—Conjoined by a transverse band across the head. Outer margin of ear-conch uot distinctly concave in its upper half. Chin.—A triangular naked space (in skins and alcohol specimens often contracted to a deep furrow), flanked by two oblique warts, converging downwards. Wings.—Tbird and fourth metacarpal subequal in length, fifth the longest. First and second phalanx of third digit subequal. Species.—Four species were catalogued by Dobson in 1878: M. hirsuta, megalotis, minuta, Behni. Since that time the following three species have been described : M. brachyotis (Dobson, 1879), M. microtis (Miller, 1898), M. hypoleuca (J. A. Allen, 1900). I have satisfied myself that M. Behni is a Glyphonycteris ; the same is probably the case with M. brachyotis ; ard M. hypoleuca is appareutly indis- tinguish«ble from M. minuta. ‘The genus Micronycteris, as here restricted, therefore comprises the following four species: M. megalotis, microtis, minuta, and hirsuta.

Teeth.— pz higher than p3 and p43 p; and p, subequal in height (ps, often a trifle lower) ; p; in cross-section at base a little smaller than p,.—p’ about half the height of the canine ; p® and p* subequal in height. Tip of the principal cusp of p* situated only very slightly in front of a vertical line through the middle of the base of the premolar; vertical diameter of p® about equal to antero-posterior basal diameter ; external surface of p® convex. Ears.—Long and broad, reaching beyond the tip of the muzzle when laid forwards. Cross-strize on ear-conch faint and rather ill-defined; number about 13-14; distance between uppermost and lowermost stria about 11 mm. In the fully adult male the transverse band between the ears is triangular in shape, 7. e. low laterally, triangularly raised in the middle ; a small notch at the middle of the upper margin of the band (the top of the triangle). Immediately behind the band, in the fronto-parietal region, a triangular groove bordered by a horseshoe-shaped elevation of the skin ; the median, triangularly projecting portion of the band, when laid backwards, fits exactly to the triangular groove, as the lid to a box; tufts of long hairs on the posterior surface of the “lid.” The bat is no doubt able to cover and uncover: the groove by moving the band forwards and backwards. In females and young males the transverse band is much lower, not conspicuously higher in the middle than laterally ; the frontal groove is absent or, at most, very ill defined. The frontal groove (which, to my knowledge, has not been described by previous writers) is evidently analogous to the frontal sac in many species of Hipposiderus. The posi- tion is the same; the long hairs recall the hair-tuft in the Hipposiderus sac ; and, as in the majority of Hipposideri, the apparatus is characteristic of the male sex. A frontal con- cavity almost identical in structure and position is found in the males of an Oriental species of Nyctinomus (N.johorensis). Nose-leaves.— Lancet long, 7. e. its extreme length about equal to 1} its width at base. Wings.—Forearm practically naked ; some short, scattered hairs are observable on very close inspection. Wing- membranes inserted on the ankles or the base of the meta- tarsus. Length of forearm 31°8-38 mm. Foot and calcar.—The foot is comparatively small, equal to 4 or 3 the length of the lower leg. Calcar long, always longer than the foot, and always much more than half the length of the lower leg. Genera Micronycteris and Glyphonycteris. 53 Tail and interfemoral.—The postcaudal portion of the interfemoral is longer than the tail, from the anus to the tip of the last vertebra. Colour.—There are two extremes in the colour of the fur :— (1) Upperside Prout’s brown with a tinge of russet ; base of hairs pure white or washed with ecru-drab. Underside wood-brown, base of hairs scarcely lighter. (2) Upperside dull dark brown without any trace of russet tinge; base of hairs pure white or washed with ecru-drab. Underside hair-brown. The extremes are connected by several transitional stages. The variation in colour is independent of the locality and, as it seems, of the age of the individuals. Range.—The same as that of the genus. Remarks.—The large p; and p’*, the median position of the principal cusp of p®, the very small notch at the middle of the upper margin of the ear-band, the practically naked forearm, the long hand, the small foot, long calcar, long postcaudal interfemoral, and darker-coloured underside of the body readily distinguish this species from M. minuta. From M. hirsuta it differs by its smaller size and higher ear-band, from M. microtis by its much darker colour. la. Micronycteris megalotis, f. typica. 1842. Piyllophora megalotis, J. E.

My reason for raising the question is this:—In the proportionate size of the ears and in the cross-markings of the conch ™. hirsuta is similar to M. megalotts. Butin two british Museum examples of JL. hirsuta the ears are very short, reaching only a little beyond the eyes when laid forwards, and the cross-markings on the inner surface of the conch are very strongly defined and crowded into a space of 6-7 mm.; they are, on the whole, puzzlingly like the type of ear described by Mr. Miller in M. microtis. ut the ears of these two VW. Airsuta have indubitably been singed (the b .ts may have been caught while trying to esc.:pe {rom a burning tree, or, perhaps more likely, been found dead in a hole of a partially burnt- down tree); though very much shrunk they have, however, preserved their oriyinal shape ; they have simply contracted into scarcely 3 their natural size, and, as a consequence of that, the cross-markings have become very sharply defined, prominent beyond the plane of the conch, and crowded into a small space, and the ear-conch thick and stiff. Is the satce, perhaps, the case with the ears of the only specimen known of M. microtis? If so, M. microtis is very closely related to VW. megalotis, differing, as it seems, only in the much lighter colour of the fur (which, however, may be indicative of a light phase only) and, perhaps, a slightly smaller size. 56 Mr. K. Andersen on the Bats of the some of them white, others greyish white below, and have the basa of the hairs of the upperside white. If, therefore, there is no other difference between M. hypoleuca and M. minuta, the former cannot be distinguished from the latter. I understand from Dr. Allen’s description that he had no example of M. minuta for comparison. Teeth.—p; much lower than p,, only a little higher than the cingulum of p .—p* much lower than p*, only a little higher than the cingulum of the canine. Principal cusp of p® situated near the anterior end of the tooth; vertical diameter of p® markedly shorter than antero-posterior basal diameter; external surface of p’ concave. Ears.—Essentially as in M. megalotis: long and broad, extending beyond the tip of the muzzle when laid forwards. Cross-strize on ear-conch faint and rather ill-defined ; number about 11-12; distance between uppermost and lowermost stria about 10 mm. In the fully adult male the transverse band between the ears is as high as, or, rather, still higher than, in the male of M. megalotis; but the median notch is extremely deep, reaching practically to the base of the band, thus dividing it into two distinct triangular lobes. A coat of long hairs on the posterior surface of the band. Frontal groove as in the male of M. megalotis. Spirit-specimens of females are not available for examina- tion. Nose-leaves.—Kssentially as in M. megalotis, but lancet comparatively a trifle shorter, its extreme length being on average equal to about 1} its width at base. Wings (compare the wing-indices below, p. 65).— The metacarpals are proportionately shorter than in M. megalotis ; an inspection of the measurements (below, pp. 64-65) will show that whereas M. minuta has the forearm of precisely the same length as M. m. mexicana, its metacarpals are as short as in the small southern race, M. m. typica; this, together with a shortening of the proximal phalanges, makes as a tutal result a proportionately shorter hand in M.minuta. The second phalanx of the fourth digit is practically equal to the first phalanx (in M. mega/otis decidedly shorter than the first phalanx). The muscular part of the forearm is densely haired. Membranes inserted on the ankles or the extremity of the tibia. Forearm 36-37°5 mm. Foot and calcar.—The foot is comparatively large, much more than 4 the length of the lower leg. Calcear short, always shorter than the foot, aud less than } the length of the lower leg. Genera Micronycteris and Gly phonycteris. 57 Tail and interfemoral.—The postcaudal portion of the interfemoral is shorter than the tail. Colour.—Above as in M, megalotis, below cousiderably lighter. Upperside Prout’s brown, base of hairs white ; underside whitish or greyish white in the middle, drab on the flanks. Range.—Brazil, from Santa Catherina in the south to Para in the north. Extending to Colombia, if M. hypoleuca is identical with M. minuta. Specimens examined.—11, from:—Santa Catherina (3) ; Para (4) ; ‘‘ Brazil”’ (4). Remarks.-—On hasty inspection M. minuta bears no small resemblance to M. megalotis. The two species are practically alike in the shape of the skull, in the ears and nose-leaves, and in the general size; M. minuta is not, as its technical name might suggest, smaller than M. megalotis. But M. minuta differs in the following important respects :— In the very conspicuous reduction ‘of p; and p®; in having the transverse band between the ears divided into two separate triangular lobes ; in having the proximal half of the forearm densely haired; in the proportionately shorter hand; in the larger foot, short calcar, short postcaudal imterfemoral, and ligiter-coloured underside of the body. 4. Micronycteris hirsuta, Ptrs. 1869, Schizostoma hirsutum, Peters, MB. Akad. Berlin, p. 397.—Type: 3 ad., in alcohol ; locality unknown; Paris Museum. Skull—Similar in shape to the skull of M. megalotis and M. minuta, but much larger, and brain-case less vaulted and raised above the facial region, the profile-line, from the uppermost point of the brain-case to the nasals, therefore less concave. Teeth. — Cutting-blade of # markedly less compressed antero-posteriorly than in MM. mega/otis and minuta. Upper premolars as in M. megalotis. Almost the same is the case with the lower premolars : p» slightly higher than p,, which is slightly higher than p,. Ears.—Proportionate size as in M. megalotis and minuta ; number of cross-ridges 13-14, covering a space of about 1] mm. Transverse band between ears, in both sexes, very low, straight (not higher in the middle), and without median notch. There seems to be no frontal groove (the two specimens examined of this very rare bat are in a bad state of preservation). Ce Mr. K. Andersen on the Bats of the Nose-leaves.—Lancet proportionately shorter, its extreme length only a little longer than its width at base. Wings.—Wing-structure almost precisely as in M. mega- lotis, the only noteworthy difference being the somewhat shorter metacarpals. Forearm haired almost to the extremity. Membranes inserted very nearly on the ankles. Forearm 435-45 mm. Calcar.—Slightly longer than the foot. Specimens examined.—Pozo Azul, Costa Rica, 200 m. (g ad., 9 ad.). One skull.

Skull.— Facial portion, immediately in front of orbits, very conspicuously inflated. Anterior nasal openings more hori- zoutal in position than in Micronycteris, directed chiefly upwards. Basioccipital pits, antero-internally to cochlee, very deep. Dentition—? very pronouncedly chisel-shaped, its cutting- blade broad from side to side, extremely thin antero-poste- riorly. Canines short, their antero-posterior basal Boh: equal to their vertical diameter. Inner cingulum of developed into a conspicuous rather broad “heel” ; tip of the principal cusp of p*® anterior in position, situated in a vertical line through the front end of the base of the pre- molar ; antero-posterior basal much longer than vertical diameter.

Chin —As in Micronycteris. Wings.—Third and fifth metacarpal subequal in length, fourth the shortest. Second phalanx of third digit from 14 to 1} the length of the first phalanx. A comparison with M. megalotis and hirsuta = M. minuta the hand is peculiarly shorteued) will readily show how this modification of the wing-structure has been effected (see wing-indices, below, p. 65) :-—In Glyphonycteris the fourth metacarpal has, very nearly, the same proportionate length as in M. hirsuta, whereas the fifth and, still more, the third Genera Micronycteris and Glyphonycteris. 59 have increased in length, making as a total result the fifth and third metacarpal subequal, the fourth the shortest. In Glyphonycteris the first phalanx of the third digit is shortened, the second correspondingly lengthened ; in other words, the joint between the two phalanges has been removed in proximal direction (compare wing-indices of G/ypho- nycteris and M. megalotis). ‘The joint between the first and second phalanx of the fourth digit has been similarly removed in proximal direction, making the latter phalanx decidedly longer than the former. Species.—The genus was’ based on G. sylvestris. Au examination of the British Museum material has convinced me that Peters’s M. Behni is a Glyphonycteris; the same is probably the case with Dobson's M. brachyotis. Range.—From Brazil (Matto Grosso) and Peru through Guiana to Central America. 1.

Notwithstanding these deficiencies in the description of the species, I think there can be little doubt that it is a member of the genus Glyphonycteris :—(1) The cusp of the first upper premolar (p®) is, aecording to Dobson, “very oblique, touching the canine” ; this probably means that the tooth is remarkably long in antero-posterior direction, and the cusp situated at the front eud of the tooth, as in Glyphonycteris : (2) the ears (“much shorter than head,’ tip ‘ obtusely pointed”) are as in G Behni, not as in a Micronycteris : (3) Dobson’s omission of any reference to the ear-band is probably an indication that it is absent: (4) the second phalanx of the third digit is much longer than the first phalanx, also one of the features of Glyphonycteris iu contra- distinction to Micronycteris: (5) unfortunately Dobson only gives measurements of the third and fifth digits, but the wing-indices, as derived from these measurements, are more in accordance with those of Glyphonycteris than with those of Micronycteris. G brachyotis seems to be precisely of the same size as G. sylvestris, but the calcar is stated to be longer than the foot.

Cockrrett, University of Colorado. Nomada (Xanthidium) subrutila, Lovell & CkIl., 1905. Boulder, Colorado, at flowers of Pulsatilla hirsutissima, one ¢, May 1, 1906 (Marie Gill). This species was previously known by a single male taken in Maine. The Colorado example has the flagellum duller and distinctly deuticulate, and the b. n. passes a short distance basad of the t.-m., but they otherwise agree. In my table of Rocky Mountain species the insect runs to N. civilis, from which it is easily known by the denticulate flagellum and other characters. It is ncarest to N. lutevloides, “Robertson, and it is not unlikely that it will prove to be only sub- specifically distinct. Nomada pulsatille, sp. 0. ? —Length about 7} mm. Red and _ black, mith no yellow anywhere ; mandibles simple ; head broad, facial quadrangle conspicuous'y broader than long; head red, with the cheeks posteriorly, a large patch enclosing the ocelli, the middle of front (enclosing no red spot), the region about antennae, and a broad mark extending halfway down sides of clypeus all black; the supraclypeal area is black, with a red spot; hair of head and thorax above fuscous, black on scutellum and scape; that on metathorax, pleura, and cheeks pallid; antennz long, en- tirely ferruginous, third joint about as long as fourth; mesothorax coarsely rugoso-punctate, red, with a broad median black stripe ; “scutellum red, flattish, aud not bilobed ; metathorax nearly all red except a broad median black band; pleura red; tegule shining coppery red, rather closely punctured. Wings very dark at apex, stigma ferru- ginous, nervures dark fuscous ; second s.m. not especially broad above ; b. n. a moderate distance basad of t.-m. Legs bright red, the coxze and trochanters marked with red, and the hind femora with two more or less suffused black stripes behind; hind tibiz and tarsi behind with fine golden tomentum. Abdomen broad, oval in form, very shiny chestnut-red, the hind margins of the first two segments strongly blackened, but not really banded; first segment with a broad black mark (enclosing a red dot) on each side 70 Mr, T. D. A. Cockerell—Deseriptions and of base and a linear one in the middle; apical band of tomentum on fifth segment narrow; pygidial plate broadly rounded ; venter red, without markings. Hab. Boulder, Colorado, at flowers of Pulsatilla hirsu- tissima, April 20, 1906 (Cockerell). In the table of Rocky Mountain species (Bull. 94, Colo. Exp. Sta.) this runs to 68, and runs out because the abdomen has no yellow spots. From N. Packardiella it differs by the much broader abdomen, without yellow spots or distinct black bands, the golden pile on the entirely red hind tibiz, &e. From N. Clarkii it differs by its smaller size and the details of the coloration of the abdomen, but the two are closely allied. From WN. /atifrons it differs by the broad abdomen &c. It is also related to N. valida. There is quite a strong superficial resemblance (as seen without a lens) to N. polyacantha, Perez, from Barbary, but that species has the b. n. meeting t.-m., the mesothorax black, &e. Nomada undulaticornis, sp. u. 3g .—Length about 8 mm. Black, lemon-yellow, and ferrugimous ; mandibles simple ; anterior coxee pointed at apex, but not spined ; head coarsely sculptured, black, with the labrum, base of mandibles , cly peus except upper lateral margins, and lateral face-marks (ending very narrowly on orbital margins below level of antennz), all yellow; facial quadrangle longer than broad ; pubescence of head and thorax rather abundant, pallid, with an ochreous tint, face with appressed silky hair; scape not greatly swollen, yellow in front ; flagellum yellowish ferraginous beneath, above black about as far as the eighth (antennal) joint; third antennal joint about as long as the “fourth, apical joint pointed ; joints 6 to 9 strongly undulate beneath, or, one might say, buberculate : mesethorax entirely black, very coarsely and contiuently rugoso-punctate; tubercles red ; a small red mark on anterior part of pleura ; scutellum strongly bigibbose (mammitorm), the gibbosities red ; meta- thorax eutirely black, rugoso- plicate basally ; tesulie red, dullish, closely punctured. Wings strongly ‘dusky at apex, stigma ferruginous, nervures fuscous; second s.m, rather narrow; b. n. going only just basad of the oblique t.-m. Legs red, coxve largely black, middle femora with the basal two fitths behind black ; hind femora mostly suffused with black on both sides. Abdomen broad, convex, dark red, Records of Bees. 71 with the basal half of the first segment black, the apical margins of the first two segments infuscated ; the extreme bases of the second to fourth (at least) segments black; the second segment with a large yellow patch on each side, the third to fifth with yellow bands, very narrowly interrupted in the middle, the sixth with a large transverse yellow patch ; apical plate deeply notched, only moderately broad; venter with a few small yellow marks. Hab. Boulder, Colorado, at flowers of Pulsatilla hirsu- lissima, April 20, 1905 (IVY. P. Cockerell). I thought at first that this was the male of N. pulsatille, but there are so many differences that it seems best to regard it as distinct. In the table of Rocky Mountain species it runs to 62, but runs out because of the rather small size and red on scutellum. It is known from WN. vicinalis by its smaller size, total absence of yellow on thorax, &c. ‘There seems to be some affinity with N, denticulata, Rob. Nomada flammigera, sp. n. ? .—Length just over 8 mm. Mandibles simple; head and thorax red, with black markings and no yellow ; abdomen narrow, light red, with a sericeous surface, and a round cream-coloured spot on each side of second segment, but no other light markings. Head broad, face conspicuously broader above than below ; Jabrum with a small tubercle; front above antenne broadly black, but no black at sides of clypeus; ocelli on a small transverse black area; cheeks posteriorly black ; antenne long, all red, except that the end of scape is black behind; third joint conspicuously shorter than fourth, but still much over half its length; hair of head and thorax very scanty above, but snow-white patches showing on cheeks beneath, lower part of pleura, metathorax, &c. ; mesothorax with a median black band, the red on each side of which is deeply incised by black auteriorly, producing the appearance of flames; scutellum and metathorax red, the latter with a rather weak black band; pleura and tubercles red; tegule light red. Wings dusky, especially at apex, with the usual light area; stigma and nervures fuscous; seconds.m. broad above, thiid narrowed almost to a point; b. n. passing far basad of t.-m. Legs red ; middle femora blackened at base; hind femora much blackened in front and behind; spurs creamy white ; basal joint of hind tarsi black, contrasting with the bright red tibia and the red small joints of tarsi. Abdomen without 12 Mr. T. D. A. Cockerell— Descriptions and black above, except a couple of black spcts on each extreme side of first segment ; beneath, the first segment has a large black fish-tail mark, the prongs long, and the hind margins of the first two segments are suffused with dusky. Hab. N. Yakima, Washington State, May 15, 1903 (Eldred Jenne). From Mr. Melander, with his no. 18. In the table of Rocky Mountain species this runs to 70, but is quite distinct from N. Sayi. In Robertson’s table it runs to 4 (N. Cres- sonu and Sayi), but is not identical with the species there indicated. The insect reminds one strongly of some of the species of Gnathias. Also at N. Yakima, but on June 5, Mr. Jenne took Nomada erythrochroa, Ckll., of which only one specimen (from Pasco) was previously known. Centris Morsei marginata (Fox). The Centris marginata of Fox is evidently only a variety of Morsei, as Mr. Fox suspected. The original type, which is before me, shows that the abdomen is not bare, as Fox states, but is pruinose-pubescent exactly as in Morsei. The lack of pubescence on the middle of the thorax is due to abrasion. The fourth antennal joint is red beneath. A second specimen of this form has been taken by Dr. F. H. Snow at the San Bernardino Ranch, Douglas, Arizona, 3750 feet, August. Centris atripes, Mocsary. Renewed study convinces me that C. Fori, Friese, must fall as a synonym of C. atripes. The species is to be added to the fauna of Arizona, as Dr. F. H. Snow took two males at the San Bernardino Ranch in August. At the same locality Dr. Snow took Protowea gloriosa (Fox), also new to Arizona. Ovea tristis, Gribodo. San Bernardino Ranch, Arizona, Aug. (F. H. Snow), New to the United States.

The eyes of the female are of a beautiful deep sea-green (bluish-green) colour. aah Snowi, sp. na. 3 .— Length about 75 mm. Black, with coarse si fulvous pubescence ; clypeus black ; labrum dull yellowish white; mandibles mainly rufous ; antenne ferruginous, the flagellum subfuscous above, with the sutures darker ; tegulze large, shining, translucent apricot-colour. Wings hy valine, slightly } yellowish, the apex broadly dusky ; the large stigma and the nervures ferru- ginous. Abdomen rather pointed for an Ezxomalopsis, having the sides and apex of the first segment and base of the second broadly ferruginous ; no distinct hair-bands on abdomen, but much long coarse hair. Legs bright ferru- ginous, the long plumose hair on hind tarsi behind largely blackened ; hair of legs otherwise very pale fulvous. Labial palpi with first joimt more than twice length of second ; maxillary palpi long and slender. [ace densely covered with ‘silky pale fulvous hair; eyes dark sea-green; meso- thorax very shiny, with strong punctures except in the middle, where it is impunctate ; second submarginal cell variable, narrow and much narrowed above, or comparatively broad, receiving the first r.n. very near the apex, or not much beyond the middle; b. n. meeting t.-m., or passing a short distance basad of it. Runs in Friese’s table (1899) to 6, and runs out because of the red legs &e. Hab. Brownsville, Texas, June, 3 g (F. H. Snow). Xenoglossa pruinosa limitaris, subsp. un. g.—Clypeus without any yellow spot; hair of head einereous, with black hairs sparsely intermixed on face and vertex ; hair of thorax above pale, with only a slight fulvous tint. Legs red, more or less clouded with blackish ; abdomen very black and shiny, with the usual bands much reduced. Looks like a distinct species, but I find no structural differences from pruinosa. Hab.

Tetralonia Edwardsii vagabunda, CkIl. Tn my original account of this bee (Trans. Amer. Ent. Soc. xxx. p. 95) I stated that it was from flowers of Onosmodium. During my absence in June 1905 my wife collected a series of bees from the flowers of a plant which she took to be Phacelia, and so labelled them. I did not see the plant in flower, but later in the year we found what appeared to be the same, with abundant fruit, and it was Onosmodium caro- linianum. This year we have found the original plant in flower, and it is Phacelia heterophylla, Pursh; but growing in the same places, and almost exactly similar in foliage and manner of growth, is the Onosmodium. Such resemblance between two plants growing under the same conditions, but of different families and having quite different flowers, is interesting. The following bees were taken by my wife from flowers of Phacelia heterophylla at Boulder :—Halictus meliloti, Ckll., Dialictus anomalus (Rob.), Alcidamea simplex (Cresson),° Megachile brevis, Say, Tetralonia Edwardsti vagabunda, Ck\l., Ceratina nanula, Ckll., and C. neomezicana, Ckll. At Ward, Colorado (9000 feet), a Phacelia closely allied to heterophylla was found in quantity. It was recorded at the time as P. circinata, following Coulter’s manual; but it is not the true species of that name, and I suppose that it must belong to P. alpina, Rydberg, 1900. It proved very attractive to bees, and the following were collected on it at Ward in July by my wife and myself :—Colletes phacelie, Ckll., Anthidium emarginatum, Say, A. conspicuum, Cress., Osmia propinqua, Cress., Monumetha argentifrons, Cress., Megachile latimanus, Say, M. vidua, Smith, Bombus Ed- wardsii, Cress., var., B. iridis phacelie, Ckll. TuyGater, Holmberg. In Trans. Amer. Ent. Soc, xxxii. p. 115, I called attention to the identity of Thygater with Macroglossapis, and gave reasons for supposing that the latter had priority. I learn On new Species of Acreeidee from Uganda, 75 from Mr. J. C. Crawford, however, that Holmberg, in Actes Acad. Cordoba, v. p. 1383 (1884), remarked that Tetralonia - terminata, Smith, had only three joints to the maxillary palpi, and might form a new genus Zhygater. ‘This slight reference has been overlooked by all subsequent authors, but I think it will hold the name, giving Thygater priority. The genus consists of the following known species :— Thyygater terminata (Sm.), 7. chrysophora, NWolmbg., T. analis (Lep.), T. albilabris (Cress.), 1’. montezuma (Cress.), 7’. modesta (Sm.), 7. rubricata (Sm.). Bombus Kohli, n. 0, Bombus carbonarius, Handlirsch, Ann. naturh, Hofmus. Wien, 1888, p. 242. (S. America.) The name is changed because of B. carbonarius, Menge, 1856, from Prussian amber. As Friese has already named a Bombus after Dr. Handlirsch, the present insect may bear the name of another distinguished naturalist of Vienna, I possess the species from Villa Encarnacion, Paraguay, collected by Mr. Schrottky. Dr. Handlirsch, to whom I wrote concerning the preoccupation of carbonarius, replied that he did not himself intend to propose a substitute. Sphecodes hesperellus pulsatille, subsp. n. ? .—Like S. hesperellus, Ckll., but somewhat larger; the wings longer (about 7 mm.), blackish, quite dark, not reddish as they are in hesperelius ; abdomen darker, deep chestnut- colour; rugee of metathoracic enclosure more numerous, very distinct. Superficially like S. pecosensis, Ckll., but very distinct by the shining mesothorax, with scattered punctures. The first abdominal segment is sparsely punctured, Hab.

By Gertrupe Ricarpo. [Plates III.-VI.} Hanmarorora, Meigen. Hematopota, Meig., Iliger’s Mag. ii. 267. 40 (1803). This genus is readily distinguished by the peculiar markings of the wings, but the species are not easy to describe. Loew gives what he considers good characteristics for the distinction of the species in his Dipt. Siidafrik., relying on the shape of the head, the position, shape, and size of the paired spots, and the absence or presence of the unpaired spot, and, in alesser degree, on the markings on the face ; the shape of the antennz he considers a doubtful character, of the Family Tabanide. 95 especially as to the incrassate or cylindrical first joint, but the legs afford good characteristics. He considers the wings very difficult to describe, but gives some of the chief points. To the above I am inclined to add the shape and size of the frontal callus as useful, the general shape of the antenne (which vary consider ably), and to rely upon the presence or absence of rings on the legs and the possession of a white base to the tibiz. Though the markings of the wings may be relied upon as a rule, there is no doubt that they vary slightly in different specimens of one species, as in the shape or length of the apical band and in the presence or absence of the pale markings at the openings of the cells. The rings on the legs also are not to be implicitly relied upon, a second faint pale ring sometimes appearing in a species which, as a rule, has only one ring ; this occurs chiefly on the fore tibize. My tables are drawn up only for the females. Those species marked with an asterisk denote there are specimens of them in the British Museum collection. Through the kindness of Mr. J. A. Gerald Strickland, who has devoted a great deal of time and trouble to the work, I am enabled to give photographs of the wings of all the new species but one, of four of Bigot’s types, and of two of Walker’s types, which it is hoped will be of assistance in the identification of the species and will save the wearisome labour of reading through long descriptions of the intricate markings of the wings. The actual colouring of the wings is given in the letterpress as nearly as possible as it strikes the naked eye. ‘The magnification is approximately ten diameters. The species described by Wiedemann as Hematopota coarctata (Auss. zweifl. Ins. p. 578) from South Amercia does not belong to this genus, but to Acanthocera, Macq., as surmised by Bigot (Bull. Soc. Zool. Fr. xvi. p. 74, 1890), and is included in my table of the latter genus in Ann. & Mag. Nat. Hist. xiv. (7) p. 363 (1904). This genus does not occur in South America. Palearctic Region, For a catalogue of the Hematopota of the Palearctic _ Region, that of Bezzi, published 1903 in his ‘ Katalog der palaarktischen Dipteren,’ should be referred to. The following amendments to it should be noted, viz. H. lusitanica, Guér., is a distinct species, not a synonym of H. pluvialis, L., and H. tristis, Bigot, is a synonym of H. pluvialis, L., not a distinct species. ge 96 Miss G.

The type is much denuded and deteriorated, but may be easily known by the dark colour of its wings, s, which are a reddish brown with clearer spots and markings ; ; the abdomen is apparently black and the legs reddish with some black colour. Hematopota pallens, 2 , Loew. Six females from Algeria, 21°. vii. 93 (Eaton), 94. 114. These answer to Loew’s description, but the first joint of the antennee is grey, not black.

This species, originally described from a specimen from Tangiers, must be very nearly related to, if not identical with, of the Family Tabanide, Qi HT, italica, both species being distinguished by the cylin- drical long first joint of the antenne. The characters given in the table to distinguish the two species are taken trom Schiner and other authorities, but will probably not prove satisfactory, judging from the material in the National Collection, which, however, is too poor to throw further light on the question. Hematopota italica, 8 2, Meigen. One female from Nicosia, Cyprus (Miss M. D. Bates), 1903. 64. One female from France. Mik, in ‘ Fauna Hernstein,’ Becker, iii. p. 515 (1886), distinguishes this species from H. pluvialis by the cylin- drical first joint of the antennze, which is as long as the third joint and hardly thicker, and adds that the grey tomentum covering it is so thick that only here and there is the shining black colour to be seen through. Hematopota pluvialis, 8 9, Linn. Specimens are in the Brit. Mus. Coll. from Norway, Leenane, Co. Galway, Gloucestershire, Avon Valley, Boppard on the Rhine, Alps, Spain, The Hague, Italy, and France. It is distinguished from H. italica by its thickened first antennal joint, which is distinctly wider in the middle and much shorter than the third joint, and the bright black colour is not obscured by grey pubescence. The H. tristis, 2, Bigot, type, with the exception of the more yellow colour of the middle and posterior femora, is identical with this common European species; the type comes from Japan. Hematopota lusitanica, 2 , Guérin. Five females from Portugal (O. Thomas), 98. 99. A large blackish species, evidently distinct from H. crassi- cornis ; but at present the only distinction I can give to separate them is the larger size of the above.

O.- Grant), 93. 95. The male of this species may easily be distinguished by the wholly black colour of the antennz and by the very thick first joint. The female is less easily distinguished from that of H. pluvialis, but Strobl, in Mittheil. Ver. Steierm. 1892, xviii. (1893), recognizes it by the extraordinarily thick first jomt, which is short, stout, and not constricted near the tip ; only at its base is it obscured by grey tomentum ; the shining black band above the antenne is narrower and not produced above in the centre ; the third joint of the antenne is only red at the base. In H. pluvialis tle first joint is much slenderer, covered with grey tomentum to the middle and strongly constricted before the tip; the red colour on the third joimt is more extended, the black band broader, produced in the centre as a triangle. The four males collected by me form part of a series of two dozen or so caught in one week, resting on the highest and sunniest parts of a stone wall round an unoccupied farmyard ; no females were to be seen. I was not successful in discovering their breeding-place. Nearctic Region. There are only two species known in N. America, both said to be fairly common. There was a specimen in the British Museum Collection labelled “N. America” and placed under H. punctulata; it is apparently a specimen of Hi. variegata, and certainly does not agree with the description of either of the N.-American species ; the locality-label is probably incorrect.

The described species of Hematopota from this region number nineteen, counting H. ruficornis, &, Macq., and H. ruficornis, §, Walker, as two distinct species, and H, dorsalis, Loew, as a synonym of H. decora, Wk. ; of the Family Tabanide. 99 thirteen of these are from South Africa, two from West Africa, and five from East Africa. Ten new species are described in this paper, of which five come from Uganda, four from East Africa, and one from the Transvaal, bringing up the total of described species to thirty. Loew’s Dipt. Siidafrik. should be consulted for species from South Africa. The character given in the table of the first joint of the antennz as incrassate or not incrassate should not be regarded as absolute, as it is difficult in some cases to decide under which head a species should be placed. I have inter- preted incrassate after Mik’s definition (‘ Fauna Hernstein,’ Becker, iii. p. 515, 1886), viz. when the first joint is elliptical in shape, that is distinctly widened in the middle looked at from above, it is incrassate as distinguished from simply cylindrical or not incrassate.

Ricardo on the Genus Heematopota sate, with long black pubescence; the second joint round with black hairs; the third wide, rather short, black at its extreme apex. Frontal callus broad, black, shining, barely reaching the eyes on its anterior border, receding from them entirely on the posterior border, which is straight ; the spot between the antenne black, being a continuation of the callus ; brown rings round the antenn; the paired spots small, black, not reaching the eyes; the forehead yellowish brown near the callus, darker on the vertex. Thorax brown, with three yellowish-brown linear stripes; a large oblong spot at the suture on each side-stripe and another one at the base of each stripe ; sides of thorax grey, the pubescence on the dorsum spare and short, of a pale yellow colour, on the sides with long black and then white hairs. Scutellum brown, with pale yellow pubescence. Abdomen dark brown, with large, irregular-shaped, grey spots on each side, almost reaching the anterior border of each segment, but not the posterior border; the posterior borders of the segments of the same colour, widest in the middle, the sides partly grey ; underside greyish. Legs yellow and brown, the femora yellow with white pubescence, which is thickest on the fore femora ; all the tibiae have two yellow rings; the tarsi are darker on the apical half of the joints; the tibie and tarsi with black pubescence. Wings greyish, with yellowish- brown stigma and veins, the pale markings fairly distinct, the apical band short, single. Length 8 mm. In some of the specimens the paired spots are larger and reach the eyes. Pl. III. fig. 1, type (female). Hematopota ruficornis, 9 , Walker. Type, 68. 4 (Saunders), Natal. One female from Cape Town (H. A. Spencer), 91. 29. The type is a well-preserved specimen. The species is distinguished from H. hieroglyphica, Gerst., by the characteristics mentioned in the table, and also by the presence of spots on the face, whereas they are appa- reutly absent in Gersticker’s species, and the transverse callus is shining red-brown, not pitchy black. From H. meteorica, Corti, it is distinguished by the absence of any large brown longitudinal band on the underside of the abdomen, and only the extreme tip of the antenne is black. The following redescription may be found useful :— A red-brown species, with distinct grey spots on the abdomen and testaceous antenne. of the Family Tabanide. 103 Face grey; the spots under the antenne are red rather than black, as is also the transverse stripe, which is in- distinct and broken up into red dot-like spots. Palpi reddish, with dense black pubescence above and some grey hairs below. Antenne rather long, the first joint light yellow, cylindrical, but not very slender, with black pubescence ; the second the same colour, with similar pubescence; the third reddish, only the last divisions black, a little longer than the first two joints together. Frontal callus the same colour as the first antennal joint, slightly lunate in front, very slightly sinuous on the posterior border, narrow, reaching the eyes ; there is a faint brown double spot between the antennz ; the paired spots are brown, large, touching the eyes, the unpaired spot nearly as large, brown; the forehead yellowish brown, with grey pubescence. Thorax red-brown, with narrow grey stripes, the outer ones only reaching the suture and ending in the usual spots; sides of thorax and breast greyish; scutellum yellow-brown, with grey pubescence. Abdomen yellow-brown, darker at the apex, the spots on the sides of the segments very distinct and large, the median ones indistinct; the sides of the first three segments are grey, also the posterior borders of the segments ; the pubes- cence is chiefly grey ; the underside of abdomen faint red, with grey tomentum and pubescence. Legs yellowish, the rings on the middle and posterior legs dark brown ; the tarsi black, as are also the fore tibiz on the apical haif. Wings greyish brown, the white markings conspicuous, especially so at the opening of the fifth posterior cell; the apical band sinuous, single; veins yellowish brown ; there is a distinct ocellus above the brown stigma; all the posterior cells except the fourth with clear margins, that of the fifth being the largest. Length 9 mm. Pl. ILI. fig. 2, type (female). A smaller specimen from Cape Town seems identical. It hardly seems probable that the male described by Macquart as H. ruficornis is identical with the above, as suggested by Walker; Macquart describes his species as blackish, and _says the third joint of the antennz is a little shorter than the first joint ; the locality is Port Natal.

A small black-grey species with yellow antenne and yellow legs ; the first joint of the antenne short. 104 Miss G. Ricardo on the Genus Hematopota Face grey, with no black spots; a narrow brown stripe between the antennze and the eyes, bordering the frontal callus. Palpi the same colour, with black pubescence. Frontal callus shining black, narrow, bordering the antennz closely, leaving only a small triangular black spot between the antenne, reaching the eyes, not produced in the middle. Antenne light yellow; the first joint short, cylindrical, the second round, short, with no cup-like prolongation above, the third with the basal annulation not very wide; there are ong black hairs on the first two joints. Forehead wide, greyish, with the dark ground-colour apparent, becoming shining on the vertex ; the paired black spots are small, not touching the eyes; there is no sign of the unpaired black spot. Thorax black, with three faint grey stripes and grey tomentum, which latter covers the scutellum. Abdomen black, with a well-marked series of hoary-grey undefined spots on each side; the hind margins of the segments are also grey. Legs the same colour as the antenne; the tarsi darker ; the rings of the middle and posterior tibiz are faintly outlined by a dark ring of colour, but even this is not apparent on the fore tibiz. Wings greyish, the rosettes of light colour, fairly distinct ; the apical sinuous band is double ; stigma and veins yellowish brown. Length 8 mm. Pl. III. fig. 3, type (female). It was not possible to get a very satisfactory photograph of the wing, owing to its imperfect condition. Hematopota longa, 2 , sp. n. Type (female), Nyasaland, Nov. 1892 (H. H.

A small black species, distinguished by the long cylin- drical first joint of the yellow antenne. Face grey, with two black spots in the centre, not con- tiguous ; the usual stripe is almost resolved into a large spot bordering on the eyes and small punctuated spots. Palpi yellowish, with white hairs at the base and black hairs beyond. Antenne light yellow, the third joint darker on its apical half ; the first joint long and slender, together with the second nearly as long as the third joint; the second short, with tuft-hke black hairs below and above on its upper edge. Frontal callus black, shining, in front Iunate, with two black spots proceeding from it between the antennex; the of the Family Tabanidie. 105 hind border somewhat sinuous; the paired spots large, touching the eyes, the unpaired spot small and indistinct. Forehead brownish, with grey tomentum forming a broad arrow on the vertex (the arrow-like shape is only distinct on the type). Thorax brown-black, rather shining, with grey stripes. Abdomen brownish black, the hind borders of the segments greyish; there are indistinct grey spots on the hind segments. Legs brownish, the usual lighter rings and the base of the metatarsi yellow, the tarsi black, the fore tibiz slightly dilated. Wings brown, with the rosettes of light colour clearly marked ; the apical sinuous line broad and single, the posterior cells usually with light colour on the outer border; stigma and veins yellowish brown. Length 9 mm. PL. IIL. fig. 4, female (not type). Hematopota obscura, g ? , Loew. Two females from Karkloof and one female from Port Natal seem to agree with the description of the female given by Loew; the spots on the abdomen are hardly visible on one of the specimens. Hematopota ugande, 2, sp. n. Type (female) and nine other females from Uganda (Lt.-Col. Bruce), 1903. 206. This species is nearly allied to H. vittata, Loew, but is distinguished from it, firstly, by the absence of the black band on upper part of face; secondly, by the broader frontal callus produced to a point on the posterior border; thirdly, by the shape of the antenne, which are longer and more slender and the first joint is less incrassate; and fourthly, by the absence of the unpaired black spot on the forehead. From dH. distincta, sp. n., it is easily distin- guished by the difference in the wings, its smaller and less robust appearance, and its lighter colouring. Face brownish, covered with grey tomentum, the brown colour appearing as the usual spots and as the transverse stripe: the spare pubescence is yellowish. Palpi faint red, with grey tomentum and short black pubescence. Antenne yellowish brown, with some grey tomentum, the last divisions of the third joint deep black; the first joint slightly incras- sate, the second short, both with black pubescence, the third rather long and slender. Forehead brown, yellowish at the sides and round the spots. Frontal callus reddish brown, shining (in some of the other specimens it is darker, almost 106 Miss G. Ricardo on the Genus Ueematopota black), broad, produced on its anterior border; the paired spots large, not reaching the eyes, deep brown ; the unpaired spot is not apparent. Thorax brown, with three narrow yellowish stripes, the central one expanding beyond the suture into a broad median stripe with spots at its base, the side ones end in the usual spots, sides yellowish; or the thorax might be described as yellowish brown with three brown stripes, the middle one divided by a yellow line and terminating at the suture. Scutellum brown, with a central yellowish stripe. Abdomen brownish, yellower at the base and on the sides, where the yellow appears as large irregular spots, and the posterior borders of the segments are yellow with short yellow pubescence ; the underside greyish brown. Legs reddish brown with yellow rings; the fore tibiz only yellow at the base. Wings brown, with the rosettes more distinctly marked than in H. distincta, often lighter in the centre; veins brown; stigma dark brown; apical band single; the blotch on the apical line in the type is not always present, and may perhaps be accidental, due to a loss of colouring-matter.

A well-marked distinct species, the thoracic markings allied to those of H. vittata. In colour dark brown, the scutellum yellowish brown, the legs with the usual white or yellow rings. Face reddish, with grey tomentum; no black spots and only a trace of the transverse stripe. Palpi rather long, yellowish red, with black hairs and some white hairs below. Antennz brown-black, dull red at the base of the first and third joints, the first only shghtly incrassate, and with the second joint covered with black pubescence, the last annula- tions of the third joint black. Forehead reddish brown, the froutal callus and paired spots darker brown; the callus shining, broad, reaching the eyes, lunate on the posterior, almost straight on the anterior border; the spots between the antenne black; the unpaired spot small, joimed to a dark median spot on the vertex. ‘Thorax brown-black, the sides reddish grey; the stripes narrow, grey, the median one not very distinct, prolonged into an oblong spot with a wide of the Family Tabanide. 107 base, the outer ones ending in small spots. Scutellum yellowish brown, with very distinct grey tomentum on the anterior border. Abdomen brown, with yellowish borders to the segments and fairly distinct grey spots on each side of every segment; the underside brown, with faint yellow borders and with grey tomentum. Legs dark brown, the rings light yellow; the fore legs only yellow at the base of the tibie. Wings large, dark brownish ; the dark markings give many of the veins the appearance of being shaded ; the rosettes are fairly distinct, the apical sinuous line single, concave, short, only reaching just beyond the anterior fork of the third vein.

A small brown species with grey wings; the upper part of the face yellow-brown and the first joint of the antennze rather short. Face grey, with grey pubescence and no black spots, the upper part yellowish brown, where it reaches the callus becoming yellower. Palpi fairly long, grey, with black pubescence. Antenne yellowish, darker at the extreme apex and on the upper angle of the base of the third joint ; first jomt rather short, slightly incrassate, the second small, both with black pubescence. Frontal callus yellowish brown, shining, almost straight on both borders, reaching the eyes ; the paired spots black, reaching the eyes. Forehead reddish brown, with grey tomentum, most noticeable in contact with the callus and on the vertex ; some very short black pubes- cence apparent. Thorax brown, with three yellowish-grey linear stripes, the middle one very faint, the outer ones ending at the kase in enlarged spots ; the sides of the thorax and shoulders grey; scutellum reddish brown, the red rather apparent, probably owing to the denudation of the grey tomentum, which is most noticeable on the borders. Abdomen dark brown, with the posterior borders of the segments yellowish ; the spots on the sides grey, round; the underside grey and brown. Legs yellowish brown, some grey tomentum on the femora and tibiz and some yellow pubescence on the posterior femora, the usual rings yellowish. Wings uniformly grey, with faint pale markings; stigma yellowish brown, veins brown, appendix long. 108 Miss G. Ricardo on the Genus Hzematopota Length 9 mm. Pl Virhig ve In other specimens the abdomen is redder, the grey spots very distinct, and often a grey median line is present ; the abdomen of type is evidently denuded. A series from Buruli, Uganda, “in patch of forest on Lukogo River, halfway between Junda and Kiseliza,” have the following note :—“ Especially virulent species, complained of by natives as injuring if not actually killing their cattle ” (Lt.-Col. Bruce). Hamatopota bipunctata, 2, sp. n. Type (female), from Volksrust, Transvaal, 5400 feet, 17. xi. 1903 (Crawshay), and another female from same locality. A well-marked species with distinct ocelli and markings on the brown mottled wings; the black abdomen with two rows of grey spots. It is nearly related to H. duplicata, Loew, but the apical band of wing is not double, though at its end it throws off an indistinct branch; the first joint of the antennee is incrassate, a point not mentioned by Loew in regard to his species, and there is no median line on the abdomen, which, with the very distinct spots on each segment, distinguishes it from H. duplicata, besides other small differences. Face grey, with black pubescence and no spots, the upper part yellowish brown; above yellowish; below brown, but broken up in the centre, which is greyish. Palpi long and slender, stouter at base, tapering to an obtuse point, yellowish, with grey tomentum and black hairs. Antenne reddish brown, the basal joint densely covered with grey tomentum, with long black hairs and a few yellow shorter hairs, stout and large, in length approaching that of the third joint; the second joint small, red, with black hairs; the third red, at the apex blackish, the red basal portion broader. Frontal callus very inconspicuous, being covered with grey tomentum ; it is yellowish, small, and narrow, not attaining the eyes, hardly extending beyond the base of the antennz, straight on both borders ; the paired spots black, large, reaching the eyes. Forehead wide, brownish, covered with grey tomentum ; on the vertex a large heart-shaped brown spot, with a fine grey median line dividing it into two halves ; the pubescence of the forehead black, short. Beard white. Thorax blackish brown, with two interrupted grey stripes and a trace of a narrow median one; shoulders and sides grey ; the scutellum of the Family Tabanide. 109 the same colour, with a grey median stripe and grey on the outer borders. Abdomen black-brown, with distinct large grey spots on each side, beginning from the first segment and reaching to the last segment ; the posterior borders grey ; on the second segment the border is enlarged to a triangular median spot; traces of similar spots are seen on the other segments, but they form no distinct median stripe; the very short pubescence is chiefly black on the dark colouring and grey on the grey colouring, with the sides thesame. Under- side brown, with inconspicuous yellow pubescence. Legs brown, the knees of the femora yellow ; the tibiz with two yellow rings ; the tarsi brown, the basal joint yellow, brown at the extreme apex ; the pubescence of the legs black, with some few white hairs. Wings brown, the extreme base and fore border lighter, all the rosettes fully formed and distinct ; the stigma brown; veins brown; the appendix large. Length 10 mm. Pl. 1V. fig. 8, type (female). The second female is apparently the same species, though much discoloured. Hematopota imbrium, ° , Wiedem. Two specimens in poor preservation labelled “ South Africa (Dr. Smith),”’ 44. 6, are probably identical with this species, Loew remarks that it is difficult to distinguish between this species and his H. recurrens and H. scutellatus ; the whitish triangular spots on the median line of the abdomen mentioned by Wiedemann are not present in his species.

These specimens have not the stripes of the thorax con- tinuous as in table i. fig. 33 of Loew’s ‘ Diptera Siidafrika,’ but interrupted at the suture for a space; otherwise they agree with Loew’s description ; his type came from Caffraria, S. Africa. The figure of the antenne in his fig. 34 is evidently incorrect, the first joint being very much incrassate and the third joint much broader than usual, as noted in the text. Pl.

This species was first named H. cordigera, but was changed to the above name by the author, cordigera bemg already used for a species from Asia. The type was described with the antennz incomplete, only the first two joints remaining ; these are cylindrical, yellow in colour. The frontal callus is pitchy brown, broad, produced on its hind border, almost straight on the anterior border ; the paired spots large, brown, reaching the eyes; the unpaired spot is very small and indistinct ; the spots on the face are brown and the trans- verse brown stripe is placed on a line with them, nearly joining them. ‘The thorax is reddish brown, with three narrow grey stripes, the outer ones ending at the suture in the usual spots; there are also half-moon spots at the base of the thorax; scutellum the same colour, with grey tomentum ; the abdomen is brownish, yellower at the base, aud the posterior margins of the segments are lighter coloured. Legs yellowish brown, the fore tarsi somewhat dilated.

Length 10 mm. Pl. V. fig. 13, not type (female). Oriental Region. The described species of Hematopota from the Oriental Region are fourteen in number, given in Wulp’s Cat. Dipt. S. Asia. As the material in the British Museum (Natural History) Collection chiefly consists of new species from India and Ceylon, I have given a separate table for these and the Bigot types belonging to Mr. Verrall, including one Fabrician species of which there are specimens in the Collec- tion and one of Walker’s types from India. Another table, mostly of the older species, chiefly from the Kast Indies, including one of Walker’s types, is given as a possible help to identification. The six new species described are all from India and Ceylon. Through the kindness of Mr. Verrall I have had access to the Bigot types with the exception of H. cilipes and H. pachycera. Of the former there is an example in the British Museum Collection. Of the latter I have no know- ledge ; it is distinguished, according to the author, by the antennz being twice as long as the head, with a black abdomen, two rows of spots and the borders of the segments indistinctly grey. The author is doubtful whether these two species should belong to the genus. H. concentralis, 2, Walker, is not included in the tables, the type being without a head or wings, and no locality given. H. serpentina, Wied., described without a locality, is 114 Miss G.

XIX.—On Lamellicorn Coleoptera from Portuguese West Africa, with Descriptions of new Species. By GILBERT J. ARROW. THE British Museum collection contains a_ considerable number of interesting Coleoptera from the little-known region of Angola and the interigr of Portuguese West Africa. A few of the Lamellicornia are here described, together with a new genus and some observations on species previously known. Copride. Copris draco, sp. 0. : C. Elphenorit et C. Anceo affinis, sed multo major, clypeo fere integro, elytris politis, leviter punctato-striatis; maris capite cornu valido curvato, dimidio superiore intus utrinque perspicue serrato, thorace rugoso, medio multo elevato, utrinque excavato et lateraliter lamina maxima aleziformi predito; foemine capite cornu magno bifido, ramis retro curvatis, spatium includentibus fere ad caput equali, prothorace medio paulo elevato, lateribus minute carinatis. Long. 29-32 mm. Hab. Bihe. tor 128 Mr. G. J. Arrow on Coleoptera This is the largest and most remarkably accoutred species of its large genus yet known. It is allied to C. Elphenor, Klug, and C. Anceus, Oliv., and represents in its armature a great development of that type. The clypeus is relatively a little less wide than in those species and almost uninterruptedly curved. It is narrower in the male than in the female and the thorax is correspondingly contracted in front. In both sexes the head bears a horn, but without any similarity between the two. That of the male is over 20 mm. long in our specimen, compressed laterally so as to be rectangular i in section for most of its length, but beyond the middle it is hollowed out on its inner face and the edges of the channel are strongly dentate. ‘he horn of the female has the form of a crescent attached by a short footstalk to the front of the Copris draco, 3 and Q, nat. size. head. The two extremities are about 8 mm. apart in our examples and the footstalk about 3mm. long. The thorax in both sexés is coarsely rugose except for a small median posterior area, which is moderately punctured. In the male this median part is strongly humped and divided in front, where it terminates in three obliquely placed teeth on each side. The lateral margin in the same sex is furnished at the middle with a large leaf-like or wing-like process, curving SJrom Portuguese West Africa. 129 upwards and forwards and tapering to a point. Immediately behind this the thoracic margin is deeply excised, and between the wing-like processes and the dorsal hump are deep and very rugose excavations. In the female the lateral processes are very slightly and the dorsal hump rather more strongly indicated. In other respects the sexes are alike. The elytra are highly polished, with feebly punctured strize, and tlie pygidium is thinly and shallowly but uniformly punctured. Catharsius peregrinus, Harold. We have received this very peculiar species from Bihe and San Salvador. It is remarkable for its depressed form, elongate clypens, and the proportionately small development of its hind body. Gymnopleurus azureus, Fabr. Specimens from Bihe, agreeing with the description of G. olivaceus, Qued., seem to belong to this widely distributed Fabrician species. G. insidiosus, Péring., is, I believe, also inseparable from it. Coptorrhina angolensis, sp. n. Nigra, opaca, sat conyexa, capite crebre rugoso, clypeo bidentato, dentibus paulo productis; prothorace crebre punctato-rugoso, postice elevato, parte elevata leviter 4-acuminata, lateribus sub- tiliter marginatis, regulariter arcuatis, antice paulo divergentibus ; elytris dense punctatis, subtilissime striatis, lateribus pone humeros sinuatis. Long. 12-16 mm. Hab. Huilla (Welwitsch). This species is very closely related to C. auspicata, Péring., with which it almost exactly agrees in size, sculpture, and general form. ‘The prothorax, however, is slightly different in shape. In the male of C. auspicata it is broadest behind, the sides slightly approximating anteriorly in a sinuous line. In the new species, on the contrary, there is a slight widening towards the front and the sides are uniformly curved. The raised margin is extremely narrow, and not, as in the other species, widened at its posterior part. ‘The dorsal elevation does not extend quite so far forward, and exhibits four angu- lations, the slight outer ones being entirely absent in C. auspicata. This difference is traceable also in the females. 130 Mr. G. J. Arrow on Coleoptera Aphodiidz. Notocaulus laticollis, sp. n. Piceo-niger, opacus, capite antice levi, obtuse bidentato, fronte longitudinaliter tricarinata, carina media abbreviata, posticeque bituberculata, vertice crebre punctulato; prothorace transverso, carinis tribus integris duobusque lateralibus pone medium evanescentibus, angulis anticis obtusis, posticis rectis, lateribus valde irregularibus, interstitiis duobus interioribus grosse irregu- lariter punctatis, exterioribus leviter punctulatis ; utroque elytro fortiter tricarinato, interstitiis levibus, bistriatis, striis subtiliter punctatis ; abdomine grosse varioloso, Long. 4'5 mm. Hab. Huilla (Welwitsch). The unique specimen of this species is rather larger than the type of IV. nigropiceus, Qued., in M. Oberthiir’s collection, with which I have kindly been enabled to compare it. Its thorax is relatively rather shorter and much less constricted in front. The front angles in that form are very prominent, but in N. laticollis they are truncated and so each replaced by two obtuse angles. ‘The front margin is thickened at each end for a short distance, and at each end of the posterior margin a right angle is formed by a curved longitudinal carina about half the length of the thorax. The broad lateral flange vanishes at about the middle of this carina. In NV. nigropiceus the posterior carina is continued until it meets the anterior carina, and the outer flange is narrower and more sinuated. ‘The two median thoracic interspaces are coarsely punctured, but scarcely so coarsely as in the allied species, and the outer spaces, which in that are almost smooth, are rather sparsely pitted. ‘There are three strong carine on each elytron, each bordered by finely punctured strize. The six-jointed abdomen is very coarsely pitted, but less coarsely than in LV. nigropiceus. Hybosoride. Pheochrous dispar, Qued. Both sexes of this remarkable species, of which the elytra of the female are shining and those of the male sooty, were brought from Garenganze. ‘The imperfect female specimen of unknown origin called Silphodes dubia by Westwood nearly resembles the female of P. dispar, but is rather smaller, the sides of the prothorax are rather more curved and the punctures upon its disk rather less fine.

Both sexes of this very peculiar insect were collected by Dr. Welwitsch at Huilla. Herr Nonfried appears to have described the species from the male alone, the female having the hind tibiz only slightly swollen and the single hind claw of normal size. ‘The form of the hind tibie evidently led him to place it in Pachycnema, with which it has really no near relationship. Whereas that genus is the type of the suctorial division of the Hoplinze with membranous ligula, Areohoplia belongs to the true Hopliine, distinguished by entirely horny mouth-organs of the usual biting type. Its most remarkable feature is the form of the clypeus, the outer margins of which are drawn out into long straight compressed rods, as in the Cetoniid genus Gnathocera. Rutelidz. Anomala cerea, sp. n.

Long. 15-18 mm. Hab. Bihe, Garenganze, Bembe. This is another member of the African group of Anomalw, pale in colour, with darker tarsi and tibiz, in which the male has the larger claw of the front foot only cleft and the female those of the front and middle feet. The other species of the group are A. ammatura, Boh., clypeata, Arr., transvalensis, Arr., Distant?, Arr., ustulatipes, Fairm. (=rufa, Kolbe, tntrusa, 132 Mr. G. J. Arrow on Coleoptera Pér.), pinguis, Pér., zambesicola, Pér., repensa, Pér., and denuda, Arr. A. cerea is the largest and most stoutly built of them all, the female being rather larger and more robust than the male and the puncturation rather stronger. From specimens in our collection I believe Mr. Péringuey has been misled in recording the claw-structure of A. repensa and intrusa, an occurrence which is very liable to happen, as specimens abnormal in this respect are not uncommon. In this way I was myself misled into describing the claws of Nongoma calcarata, Arr., as differing sexually, whereas they are normally alike. Anomala funebris, sp. n. Nigra, capite, prothorace (margine postico angulisque posticis exceptis) et pedibus (femoribus posticis tarsisque omnibus ex- ceptis) lete flavis; pygidio vel rufo-flavo vel fusco, medio pallidiore ; capite dense, fere rugose, punctato, clypeo brevi, margine antico recto; prothorace nitido, subtiliter late punctato, lateribus sat regulariter arcuatis, margine postico leviter tri- sinuato ; scutello lato, fere semicirculari, laxe irregulariter punc- tato; elytris nitidis, irregulariter punctatis, costis parum per- spicuis; pygidio crebre transversim rugoso-punctato; pectore fusco, fulvo-hirto. 3. Tibiis anticis latis, bidentatis, pedum 4 anteriorum ungue majore fisso. Long. 15-16 mm. Hab. Garenganze, Bihe. Seven specimens of this species are all males. In the absence of the other sex I should have refrained from describing it, but for its very well-marked and unusual colouring. The head and thorax are bright yellow, except for the hind margin and a roughly triangular patch in each hind angle of the latter, whica are black. The elytra are entirely jet-black and shining, their surface rather thickly punctured. ‘There are no striz, but some of the punctures form quite indistinct series. The pygidium is closely and aciculately punctured, reddish testaceous, and generally more or less infuscate at the sides. Nannopopillia Damare, Ohaus. A good series of a very variable insect, which I identify with Dr. Ohaus’s Damaraland form, was brought from Huilla by Dr. Welwitsch. Only a few of them show the type of colouring described by Dr. Ohaus, in which there is a large yellow stripe upon each elytron. The greater number have from Portuguese West Africa. 138 the elytra testaceous, but slightly paler in the middle, with the suture black and a tendency to a darkening round the scutellum. ‘There is also a variety (male) in which the elytra are entirely black, and no doubt all intermediates occur. The notable disparity in breadth between the sexes given by Dr. Ohaus is not confirmed by our larger series, nor is there a sexual difference in the thickness of the batry clothing. ‘The latter is scarcely closer at the sides of the segments, as stated by Dr. Ohaus. Dynastide. Pycnoschema nigra, sp. n. Modice convexa, nigra, supra sat grosse punctata, subtus rufo-hirta, capite ante oculos utrinque acute angulato. Long. 13-15°5 mm. 6.

Hab. Huilla (Dr. Welwitsch). A small species, rather larger than the South-African P. Corydon, Oliv., and quite black above. ‘The cephalic horn of the male is rather slender and a little compressed laterally, and is represented only by avery slight prominence in the female. The thoracic excavation in the male is very small in our only example of that sex and its posterior margin is not sharply defined. Pycnoschema polita, sp. n. Paulo depressa, rufo-picea vel rufa, supra polita, fere impunctata, subtus fulvo-setosa, capite ante oculos utrinque acute angulato. Long. 18—21 mm. g. Capite rugoso-punctato, cornu compresso, valde curvato, armato ; prothorace polito, impunctato, leviter convexo, antice perparum excayato ibique paulo punctato, lateribus arcuatis, haud 134 Mr. G. J.

Capite punctato-rugoso, carina transversa, medio fere angulata munito ; prothorace leviter punctato, punctis dorsi postice fere obsoletis, lateribus medio fere angulatis, margine postico mirus sinuato ; elytris politis, obsolete punctato-striatis; pygidio dense fulvo-hirto. Hab. Bihe. This is a very distinct species owing to the extremely smooth and glossy surface of the prothorax and elytra, espe- cially in the male. Of the four specimens in our collection the two females are a lighter red colour than the male, but this difference may not be constant. ‘The male, as is usually the case in the genus, is shorter and more parallel- sided than the female. It is also almost devoid of punctures upon the thorax and elytra. The thorax is only slightly excavated in front and the hind margin of the cavity is not at all produced or carinated. In the female the sides of the thorax are less uniformly curved, there are punctures which become denser at the front and sides, and the elytra are obsoletely striate-punctate. All the males in this and the allied genera have the front tarsi thickened and their inner claws strongly hooked and very broad. The genus Astaborus, which has not hitherto been asso- ciated with Pycnoschema and in the Munich Catalogue is widely separated from it, is really a section in which the thoracic armature has reached its greatest development. As the number of known species increases it may very possibly become inseparable from Pycnoschema. 1 have identified both sexes of Astaborus Antinorti, Gestro, the female of which has a curved cephalic horn and bitid thoracic process very much as in the male, but the former is less flattened and the latter less produced and very strongly punctured all over. As there can be no doubt that the very nearly related typical species, A. armatus, Thoms., has a similar female, the armature of this sex forms the best distinctive character of Astaborus. There is also a slight elongation of the front tibiz in the male, a feature which is not found in the known species of Pycnoschema. M. Raffray seems to have overlooked the existence of the latter genus when he described four species nearly related to its typical forms, which he placed in Astaborus as a new section of that genus. The two species of Astaborus I have from Portuguese West Africa, 135 mentioned are the only ones really belonging to it. Of Pycnoschema seventeen species in all are now known, and those remaining to be discovered in all parts of Africa are no doubt very numerous. Cetoniide. Sisyraphora cicatricosa, Burm. Specimens from Huilla and Bihe closely allied to the South-African S. tomentosa, G. & P., appear to belong to Burmeistei’s Avnoplochilus cicatricosus, which was attributed by him to India, but is referred in the Munich Catalogue to Senegal. It differs from S. tomentosa in the absence of the pale markings of the upper surface and the existence of smooth longitudinal ridges upon the elytra. The scutellum, however, is not very obtuse, as it is described by Burmeister, and it is rugose except for smooth lateral and median lines. Myoderma pusilla, sp. n. Nigro-picea, vertice prothoraceque nigris, supra glabra, nitida, subtus cum pygidio longe fulvo-hirta; clypeo subquadrato, margine late reflexo, arcuato, medio vix producto, disco parce punctato; prothorace quam longitudinem paulo latiore, sat regulariter haud crebre punctato, antice emarginato, lateraliter et postice sat regulariter curvato, angulis omnibus obtusis ; scutello magno, punctato; elytris fortiter sed paulo irregulariter striatis, interstitiis convexis, subtilissime sat parce punctulatis, interstitiis 2° et 4° angustis, minus elevatis; pygidio valde convexo, antice subtilissime rugoso, postice parce transversim strigoso et fulvo-hirto. Long. 10-11 mm. Hab. Bihe, Pungo Andongo (Dr. Ansorge). This seems to be an abundant species, as I have seen a considerable number of it. It is smaller than any other described species of the genus, and its glabrous upper surface gives it a very distinctive appearance. It is clothed beneath with very coarse tawny hairs, but above is smooth and shining. The thorax is fairly coarsely but not thickly punc- tured and the elytra are almost devoid of punctures, only a few very fine ones being traceable upon the broad smooth coste. The clypeus is not pointed, although the broadly turned up margin is slightly wider in the middle than at the sides. 136 Mr. O. Thomas on new Diploa tridens, sp. n. Oblongo-ovata, obesa, fusco-nigra, corpore subtus pygidioque rufis, longe fulvo-hirtis, supra undique creberrime punctato, minute setoso, clypeo subquadrato, crebre punctato, margine valde reflexo, medio paulo angulato; prothorace densissime punctato, lateribus sat regulariter arcuatis, angulis omnibus obtusis, margine postico leviter trisinuato; scutello dense punctato; elytris con- vexis, vage costatis, subtiliter punctato-striatis atque rugoso-pune- tatis, lateribus ubique arcuatis; pygidio subtiliter ragoso, longe fulvo-hirto; pedibus piceis, fulvo-setosis, tibiis anticis acute tridentatis. Long. 14°5-17°5 mm. Hab. Bihe, Garenganze. This form is identical in its general appearance with D. (Ligyromorphus) rufiventris, Arrow, inhabiting Mashona- land, but close examination reveals differences which are very slight but sufficient for their separation. The most easily recognizable is in the armature of the front tibiz, which 1s alike in the two sexes, but constantly differs in the Eastern and Western forms. In D. rufiventris there are two broad and very blunt teeth, and a third is scarcely indicated. In D. tridens there are three well-developed teeth, and all are acutely pointed. ‘The sculpture of the upper surface is rather less rugose in the Angola species. The punctures upon the pronotum are coarse and very dense, but are mostly distinct, not completely coalescing as in the Eastern species, and the sculpturing of the elytra i is correspondingly rather less indefi- nite and rugose, producing a rather more shining appearance. I described this genus as new in 1901, having overlooked the previous existence of Diploa, which was placed by its author, Herr Kolbe, in a different subfamily to the genus Myoderma, with which it is undoubtedly nearly related. I have not seen Diploa proles, Kolbe, but that insect has a bidentate front tibia, and is no doubt very closely allied to D. rufiventris, and possibly identical. The genus Xiphoscelis no doubt has some affinity to these forms and should be placed in the Trichiine. XX.—Descriptions of new Mammals from Mount Ruwenzori. By OLDFIELD ‘THOMAS. THE first collection sent home by the members of the Ruwenzori Expedition contains examples of the following new species and subspecies. All were collected on Ruwenzort East, at altitudes from 6000’ to 13,000’, Mammals from Mount Ruwenzori. 137 1. Rousettus lanosus, sp. n. A member of the /. collaris group; the limbs thickly hairy. Size and general characters about as in Pf. collaris. Fur loose and shaggy, very abundant, its limits not sharply defined as in &. collarts ; that on the head about 8 mm. in length, mixed with a large number of much longer hairs, attaining over 20 mm. On the back the fur is thick and woolly, passes out on to the proximal half of the upperside of the forearms, and is continued thickly down the hind limbs and the wing-membrane external to them to the ankles, the feet being also thinly clothed above. Interfemoral thickly furry above, except just along its posterior margin. Below, the wings are thinly hairy to a point level with the middle of the forearm, the hind limbs and interfemoral membrane being also less thickly haired than on the upper surface. Ears narrow, rather longer than the muzzle. Palatal ridges as in LR. collaris. General colour above bistre-brown, becoming warmer posteriorly ; head darker. Under surface near broccoli-brown, but with a yellowish suffusion; some of the longer hairs quite yellow. Skull rather more delicately built than in R. collaris, the bones thinner and lighter, muzzle rather longer and narrower ; postorbital processes very thin; anterior palatine opening unusually broad. Teeth conspicuously smaller throughout, each molar and premolar slightly shorter and very much narrower than in the allied species. Dimensions of the type (measured on the spirit-specimen) :— Forearm 88 mm. Head and body 134; tail 16, tail free from membrane 9 ; head 46 ; ear 23; third finger, metacarpus 60, first phalanx 41, second phalanx 57; lower leg and foot (c. u.) 62. Skull: length to tip of nasals 42; basal length 37:5 ; zygomatic breadth 25; breadth of brain-case 17°4; palate Jength from anterior palatine foramina 19 ; breadth of pala- tine foramina 3°4; length of upper tooth-row from front of canine 14°5; the same below, 16°2; first upper molar 23 Xu. Hab. Ruwenzori East, at 13,000’. Type. Adult male (in spirit). B.M. no. 6.7.1.2. Collected by R. B. Woosnam. Three specimens obtained. This species is allied to R. collaris, but is at once distin- guishable from that and every other species by the thick 138 Mr. O. Thomas on new woolly covering of its hind limbs and its remarkably narrow molars. The occurrence of a fruit-bat at such an altitude as 13,000! is very noteworthy. 2. Crocidura niobe, sp. n. General proportions of C. maurisca, Thos., with which it shares the unusual character of the almost entire absence of long bristles on the tail. Fur about 5mm. long on the back. General colour dark blackish grey (‘blackish slate”), with indistinct silvery mottling. Under surface scarcely lighter, the tips of the hairs brown. Hands and feet pale brown ; fore claws rather smaller than hind. Tail long, slender, not incrassated, practically without longer bristles—a few present on the base only; uniformly blackish above and below. Skull normal in build, without the peculiar delicacy of that of C. maurisca; the brain-case low, the muzzle stout and conical. ‘Teeth as usual, the unicuspids broader than long, very unlike the narrow slender teeth of C. maurisca. Dimensions of the type (measured in flesh) :— Head and body 68 mm.; tail 63; hind foot 13 ; ear 10. Skull: greatest length (including incisors) 20; greatest breadth 9:1; length of upper tooth-row 8:2. Hab. Ruwenzori East, 6000. Another from 7000’. Type. Female. B.M. no. 6.7. 1.32. Original number 618. Collected 10th January, 1906, by R. B. Woosnam. Three specimens. This shrew may be readily distinguished from C. maurisca, the only species with its proportions and tail-characters, by its more plumbeous colour and its broader skull and teeth. 3. Crocidura fumosa montis, subsp. n. Size and other essential characters as in the C. fumosa of Mount Kenya, but the fur longer (hairs of back 7:0-7°5 mm.) and the general colour a dark plumbeous grey, without the distinct brownish tone so marked in true fumosa. The ends of the hairs blackish, with a silvery subterminal ring. Dimensions of the type (measured in flesh) :— Head and body 77 mm.; tail 61; hind foot 15; ear.11. Skull: greatest length (including incisors) 22; greatest breadth 10. Altitude 12,500’. Type. Female. B.M. no. 6.7. 1.28. Original number 78. Collected 16th Feb., 1906, by R. E. Dent. Three specimens, all from about the same altitude. Mammals from Mount Ruwenzort. 139 4, Myosorex blarina, sp. n. A dark short-tailed species with the mole-like appearance of M. Sclatert talpinus. Size rather less than in MW. Sclater?. Fur thick and mole- like; hairs of back about 8 mm, in length ; a number of inter- spersed longer hairs on the rump attaining 12-13 mm. General colour blackish brown, slightly iridescent, very much as in M. Sclatert talpinus; under surface scarcely lighter, more smoky brown than in ta/pinus. Hands, feet, and tail blackish, the anterior claws very large. ars very short, quite hidden in the fur. Skull stout and heavily built—compared with that of M. Sclateri it is smaller, shorter in the muzzle, but propor- tionally broader, the imterorbital region and brain-case as broad as in the larger species. Teeth rather small throughout, the anterior incisors particu- larly delicate ; relative proportions of the unicuspids as in M. Sclater?, the minute posterior one about one tenth the size of the second, which is half the size of the third, the latter being about three fourths the size of the first. Dimensions of the type (measured in the flesh) :— Head and body 74 inm.; tail 42; hind foot 14; ear 7. Skull: condylo-basal length 22-1; basal length 19°6 ; anterior breadth 7; interorbital breadth 5°5; greatest breadth across brain-case 12; length of upper tooth-series 10°8 ; height of ¢ 2. Altitude 10,000’. Type. Male. B.M. no. 6.7.1.35. Original number 252. Collected 27th January, 1906, by Douglas Carruthers. One specimen only. - “ Caught in bog and rock region.”—D, C. The interest of this animal lies in the immense extension its discovery gives to the range of the genus Myosorex, which (since the species without the extra tooth in the lower jaw were separated as Sylvisorex) has been only known from South Africa, the Zoutpansberg district of the Transvaal being there the most northern recorded locality. That the genus should turn up again at 10,000’ on Ruwenzori is a most interesting fact. The velvety mole-like fur of JL. blarina will, distinguish it from all other forms except the decidedly larger M. Sclateri talpinus of Zululand. 5. Sylvisorex lunaris, sp. n. A large slaty-grey species, with a long slender muzzle. Size much larger than in S. morto, about equal to middle- 140 Mr. O. Thomas on new sized species of Crocidura. Fur rich and velvety; hairs of back about 6 mm. in length. General colour dark slaty grey, without variegation, but with a slight iridescence on the tips of the hairs. Under surface little lighter, the tips of the hairs pale brown. Upper surface of hands and feet brown, but the flesh along their inner halves is paler than the outer ; fore and hind claws about equal in size. Tail much shorter than head and body, very finely haired, without longer bristles ; brown above, rather paler below. Skull markedly different from that of S. moro by its much larger size, slender build, and long muzzle. Teeth delicate. Unicuspids narrow, the anterior about twice the area in cross-section of the other three, which are subequal. Lower incisors uniform in thickness, not tapering, their upper edges strongly serrated, with three well-marked notches. Dimensions of the type (measured in the flesh) :— Head and body 86 mm.; tail 54; hind foot 14:5; ear 10. Skull: condylo-basal length 22; basal length 19°8; ante- rior breadth 6°4; greatest breadth across brain-case 10; length of upper tooth-series 10. Hab. Ruwenzori East, 12,500’. Other specimens from altitudes of 7000' upwards. Type. Male. B.M. no. 6. 7.1.38. Original number 643. Collected 30th January, 1906, by R. B. Woosnam. This distinct species may be readily distinguished from its W.-African allies S. morio and S. Preussi by its larger size. 6. Funisciurus Carruthersi, sp. n. A handsome yellowish-green species, with a bluish-grey belly ; something like a gigantic #. poensis. Size about as in /. pyrrhopus. Fur soft and rich; hairs of back about 13-15 mm. in length. General colour above bright yellowish olivaceous green, the hairs blackish with rich yellow subterminal bands. Along the sides of the back a suggestion of yellow lateral lines, in the position of those of the pyrrhopus group, can be made out, but these are very faint and scarcely to be distinguished from the yellow of the flanks. Under surface and inner sides of limbs bluish grey, the hairs dank slaty with whitish tips. Head like back ; eyes rimmed above and below with dull whitish or orange- whitish ; ears short, rounded, their inner surface greenish yellow like the flanks, their outer surface and a small post- auricular patch dull yellowish white. Upper surface of hands and feet grizzled yellowish. ‘Tail coloured like the body, the Mammals from Mount Ruwenzor?. 141 hairs black at base and on a broad subterminal ring, the middle ring and the ends greenish yellow; a pencil of long hairs at the tip of the tail wholly black. Skull of about the size and general shape of that of F. erythrogenys and other members of the pyrrhopus group. Nasals square, parallel-sided. Postorbital processes further forward on the skull than in erythrogenys. Teeth apparently of the same general type as in F£. erythrogenys, but m’ considerably larger. Dimensions of the type (measured in flesh) :— Head and body 198 mm.; tail 192 ; hind foot 47:5 ; ear 20. Skull: greatest length 49; basilar length 88; greatest breadth 28; nasals 13x75; interorbital breadth 12:2; palatilar length 20°2; length of upper tooth-series exclusive of p® 8°8. Another specimen (a male) has head and body 204 mm. ; tail 205. Hab. Ruwenzori East, 6500’. Type. Female. B.M. no. 6. 7.1.53. Original number 262. Collected 7th February, 1906, by Douglas Carruthers. The affinities of this handsome and distinct species are by no means clear. Its size and the indistinct lateral dorsal lines suggest a relationship to the non-rufous members of the pyrrhopus group, although it has not their characteristically marked tail, and the bluish-grey belly is unlike anything found among them. 7. Otomys Darimouthi, sp. n. Lower incisors double-grooved. J/° with only six lamine. Size rather larger than in O. Jacksont. Fur very fine, long and woolly ; ordinary hairs of back about 17 mm. in length. General colour above finely grizzled “ mummy- brown,” not so coarsely marbled as in O. Jacksont. Under surface drab-brown, the ends of the hairs pale clay-colour. Head and ears of the prevailing body-colour. Upper surface of hands and feet pale buffy. ‘ail black along its upper surface, dull buffy on the sides and below. Skull larger than in O. Jackson, its profile convex above the orbits. Upper incisors with a deep median and a fine internal groove. Lower incisors with two well-marked subequal grooves, as in O. Jacksont and typus. Laminar formula of molars 5==—*, Dimensions of the type (measured in the flesh) :— Head and body 150 mm.; tail 933; hind foot 26°5; ear 25. Ann. &: Mag. N. Hist. Ser. 7. Vol. xviii. Ly 142 Mr. O. Thomas on new Skull: greatest length 37°5; basilar length 30°3 ; zygo- matic breadth 19°5; nasals 16:5 x 6°7; interorbital breadth 4°2; palatilar length 17; palatal foramina 7; length of upper molar series (grinding-surface) 7°3. Hab. Ruwenzori East, 12,500’ (“ seen up to 13,000’ ”’). Type. Male. B.M. no. 6.7.1.54. Original number 653. ‘ollected 18th February, 1906, by R. B. Woosnam. Six specimens obtained. This animal is related to the corresponding mountain-form of Mt. Elgon, Otomys Jackson@, from 13,200’, but differs by its larger size, more uniform coloration, and the possession of only six lamine on the last upper molar. I have had great pleasure in naming this distinet species in honour of the Earl of Dartmouth, to whose generosity this splendid exploration of Mount Ruwenzori is primarily due. 8. Otomys Denti, sp. n. Incisive grooves as in OQ. irroratus, but m* with five laminze only. Colour very dark. Size rather smaller than in O. irroratus. Fur long and fine ; ordinary hairs of back about 20 mm. in length. General colour dark blackish brown (darker than “‘ bistre””) with a coppery tinge, the rump almost black, the light rings on the hairs dark tawny. Under surface and inner aspect of limbs slaty black, a few only of the belly-hairs tipped with dull buffy. Upper surface of hands and feet uniformly brownish black. ‘Tail black throughout, above and below. Skull smaller than that of O. 7zrroratus, more flattened above, its profile not so convex above the orbits, the height from tooth-row to supraorbital ridges markedly less. Incisive grooves asin O.irroratus. Molar lamine Dimensions of the type (measured in flesh) :— Head and body 157 mm.; tail 89; hind foot 27; ear 21.

Hab. Ruwenzori East, 6000’. Type. Female. B.M. no. 6.7. 1.69. Original number 56. Collected 27th January, 1906, by R. E. Dent. Three specimens. . This striking swamp-rat is readily distinguishable by its dark coppery colour, flat skull, and the presence of only five laminge on the last upper molar. 3—2—5 4—2—2° Mammals from Mount Ruwenzor’, 143 9, Dasymys montanus, sp. n. A very long-haired species, with short tail. Size medium. Fur very long and fine; the ordinary hairs of the back about 15 mm. in length. General colour above uniformly finely speckled mummy-brown, the light rings on the hairs near clay-colour. A number of the longer hairs with a greenish irilescence. Sides but little paler than back. Under surface bluish grey, the slaty bases of the hairs little hidden by the dull pale drab tips. Lars large, black, con- trasting with the general brown colour. Upper surface of hands and feet pale brown, the digits lighter. ‘Tail practically naked, the scales quite unhidden, blackish throughout. Skull shorter and broader and the zygomata more squarely expanded anteriorly than in other species. Dimensions of the type (measured in the flesh) :— Head and body 137 mm. ; tail 105; hind foot 27; ear 19. Skull: length of upper molar series 7°3. Another skull measures :—Greatest length 35; basilar length 30°6; greatest breadth 21:2; nasals 12°3x43; palatilar length 17°8 ; length of upper molar series 7-1. flab. Ruwenzori East, 12,500’. Type. Female. B.M.no.6.7.1.79. Original number 255. Collected 30th January, 1906, by Douglas Carruthers. I refer four specimens to this species, two of them of a normal colour and two apparently melanoid, rather darker than de Winton’s D. incomtus fuscus. Untortunately the skulls of the normal-coloured specimens are much damaged, but I do not think there is any reason to suppose the blackish specimens are different from the brown ones. D. montanus is readily distinguishable from all other species by its long fur and short tail. 10. Dasymys medius, sp. n. A grey species allied to D. Bentley. Size medium, rather larger than in D. Bentleye. Fur comparatively coarse and shaggy; hairs of back about 12-13 mm. in length. General colour above greyish “ hair-brown,” greyer on the head and fore-back, warmer and browner on the rump; darkened throughout by the black ends to the longer hairs. Sides greyer, passing gradually into the grey of the under surface, where the tips of the hairs are dull greyish white, their slaty bases showing through. Lars well-haired, greyish brown, not markedly darker than the general tone. Upper surface of hands and feet pale brown, Li 144 Mr. O. Thomas on new Tail rather long, thinly clothed with fine hairs, not hiding the scales, brown above and below. Skull larger than that of D. Bentleye and markedly higher in the brain-case.

No species of Dasymys have been hitherto described from this part of Africa, the nearest being the Lower Congo D. Bentleye, from which the present animal differs by the characters above mentioned. From the D. montanus of the higher altitudes of Ruwenzori it is, of course, at once distin- guishable by its shorter coarser fur and much longer tail. 11. Mus Dennia, sp. n. A small long-tailed species allied to Jf Allenit. Mammezx 2—2=8. Size about as in M. Allent and M. carillus. Fur soft and rather woolly; hairs of back about 9-10 mm. in length. General colour not unlike that of JZ. carzllus, soft buffy fawn, varying a good dealin the richness of the tone. Sides clearer and more buffy. Under surface well defined whitish, sometimes tinged with buffy. Head greyer than back ; lower part of sides of muzzle white ; area round eyes black. Ears large, naked, dark brown throughout. Upper surface of hands and feet thinly haired, dull whitish. ‘Tail much longer than head and body, fairly well haired terminally, greyish brown throughout. Skull of the same delicate shape as in Af, Allen? and carillus, and the zygomatic plate similarly little projected forward, Supraorbital edges sharply square, but not beaded. Palatal foramina much longer than in the two western species. Dimensions of the type (measured in skin) :— Head and body 96 mm. ; tail 154; hind foot 21; ear 21.

In Aus carillus, otherwise allied, there are only 1—2=6 mamme. I have been in some doubt as to whether this or a larger species obtained by the Ruwenzori Expedition should be referred to de Winton’s M. Jacksoni, founded on a young specimen from Entebbe, but the teeth of the type are more as in the larger form, and there is a distinct, projection forward of the zygomatic plate, practically absent in the present form. A mouse from Mount Kenya, obtained by Prof. Mackinder in 1899, and referred by me to J/. Jacksont, would also seem to be assignable to Mus Dennice. 12. Mus univittatus lunaris, subsp. n. General characters of the typical western J/. untvittatus, but size smaller and colour more olivaceous, not turning rufous on the rump, which is blackish olivaceous. Belly- hairs greyish tipped with buffy ; a line down outer edge of thighs also butty. Dorsal streak not sharply defined and not extending on to neck and head.

This species is related to Z. muscu/o¢des, Temm., but may be readily recognized by its rich buffy under surface. 14. Lophuromys Woosnami, sp. n. An olive-grey species with large ears and long tail. Size about as in LZ. aquilus. Fur straight; hairs of back about 10-11 mm. in length. General colour above between “olive” and ‘bistre,’” without the warmer rufous tone generally present in the East-African forms; the bases of the hairs are, however, of a rufous-brown colour. Mixed with the ordinary hairs of the back there are a variable number of buffy-white hairs, which produce a_ speckling somewhat similar to that of the grysbuck (Nototragus mela- notis), but are almost absent in some specimens. Sides rather paler than back. Colour of under surface not sharply defined laterally, very variable, ranging from near wood- brown to tawny clay-colour; the throat rather whiter. Head like back ; area round eyes nearly black. Ears very large, finely haired, black, with whitish edges. Upper surface of hands and feet pale brownish white. ‘Tail long, slender, almost naked, markedly less hairy than in the other species ; blackish above, whitish flesh-colour below.

Incisors more as in Mus than in other Lophuromys, their anterior surface not curved round in the way generally characteristic of the present genus. Molars very broad, with well-defined cusps; their pattern as usual. Dimensions of the type (measured in flesh) :— Head and body 118 mm.; tail 111; hind foot 22°5; ear 23. Skull: greatest length 30°5; basilar length 24; greatest breadth 14°3; nasals 14.x3°2; imterorbital breadth 6°7 ; diastema 8; palatilar length 12°4; palatine foramina 6°5; length of upper molar series 4°8. Alt. 6000’, Type. Adult male. BM. no. 6. 7. 1. 170. Original number 608. Collected 3lst December, 1905, by R. B. Woosnam. Nine specimens. This striking species is widely different from any of the Central- and Kast-African forms of Lophuromys, and might almost be considered generically distinct were it not that the West-African L. stkapusi also possesses some of its characters. Its large ears, long tail, and peculiar olive-coloured white- speckled fur readily distinguish the species from all its allies, and I have much pleasure in naming it after Mr. R. B. Woosnam, to whose abilities so much of the success of the Ruwenzori expedition is due. XXI.—On a second Species of the Silurid Genus Mochocus. By G. A. BouLencer, F.R.S. WHEN dealing in these ‘ Annals,’ a few years ago *, with the little-known genus Mochocus, Joannis (Rhinoglanis, Giinther), I was acquainted with one species only, as I consider Rhino- glanis typus, Gthr., from Gondokoro, and &. Vannutellid, Vincig., from Lake Rudolf, as specifically identical with the incorrectly described Mochocus niloticus of de Joannis, of which I had then received a few specimens from Assuan, where the fish bad been rediscovered by Mr. Loat. The * Vol. vi. 1900, p. 525. 148 Mr. O. Thomas on a little fish has since been found by the same collector at various localities on the Nile, between Beni Souef and Gondokoro, and a second species has been discovered by him at Fashoda and at Lake No, White Nile. For this new species I propose the name of Mochocus brevis. Easily distinguished from the preceding by the shorter caudal part of the body, the first dorsal fin being equally distant from the end of the snout and from the root of the caudal, or only a little nearer the former. Depth of body 34 to 4+ times in the total length, length of head 3 to 34 times. Occiput and nuchal shield slightly tectiform, but without a keel. Maxillary barbel reaching the extremity of the ventral fin or a little beyond. First dorsal I 6, the spine without any serration and always shorter than the head; second dorsal 9-17; anal 9-10. Caudal peduncle only a little longer than broad. Coloration as in JZ. niloticus, but pectoral, ventral, and anal fins often with some brown spots. Total length 31 mm. Forty-two specimens from Fashoda and one from Lake No. In MM. neloticus there is a series of three or four small bony scutes, ankylosed to the interneural bones, on each side of the base of the soft rays of the first dorsal fin; these little scutes, which have hitherto been overlooked, are absent in M. brevis. XXII.—On a new Figmy Antelope obtained by Col. J. J. Harrison in the Semliki Korest. By OLDFIELD THOMAS. THE British Museum owes to Col. J. J. Harrison the skull of a pigmy antelope from the Semliki Forest allied to the Cameroon species described by de Winton as Neotragus Batesi*, I have also had the opportunity of examining the skin of the specimen, which is now in Co]. Harrison’s collection. Neotragus Batesi, as shown by de Winton, is in many respects allied to both Neotragus and Nesotragus, and in the light of the present examination of the new material, including an additional example from the Cameroons, I am disposed to consider it as representing a distinct genus, whose range * P, Z. S. 1908, i. p. 192. new Pigmy Antelope. 149 would be coextensive with the great Congo Torest. This genus may be called HYLARNUS*, gen. nov. Intermediate between Neotragus and Nesotragus. Pre- maxillo-maxillary vacuities present, as in the latter. Nasals very broadly expanded posteriorly. Muzzle in front of orbit comparatively short, the anterior wall of the orbit vertically above p*, as in Neotragus, above m‘ or m? in Nesotragus. Palation (back of bony palate) about level with the hinder corner of m*, as in WVesotragus, opposite its front edge in Neotragus. Horns short, laid back nearly in the line of the frontal profile, almost as in Weotragus ; stout, conical, smooth except just at their base. Type. Neotragus Batesi, de Wint. The Eastern species obtained by Col. Harrison seems to be specifically separable from 4H. Bates?, and I would propose for it the name of Hylarnus Harrisoni, sp. n. External characters very much as in //, Bates, but the colour-contrasts are more marked, the dark colours darker and the light brighter. General colour nearer to ‘‘ cinnamon” of Ridgway, that of Batesi approaching “ russet”’; central dorsal area darkened by the black tips to the hairs. Jorehead and crown dark brown, a fine lightish line over each eye. Hairs of outer surface of ears black, of inner white. Chin and interramia nearly pure white. ‘Throat-band brownish cinnamon. Belly sharply defined white. Front of limbs dark brown, inter- rupted over the metapodials and basal phalanges by an ill- detined elongated whitish patch, which is succeeded again by brown on the penultimate phalanges. Tail imperfect in the type, its basal portion coloured like the body. Skull with the nasals even broader posteriorly than in H, Batesi, running out on each side to a well-marked angle. Premaxillo-maxillary vacuity larger in the single specimen. Horns longer and set at a slightly greater angle upwards. Dimensions of the typical skull :— Greatest length 110 mm.; basal length 96°5; greatest breadth 52; muzzle to orbit 51; nasals 87 x 23; breadth of brain-case 36 ; muzzle to front of p? 36; palate length 66; length of upper tooth-series 32. * adpvés, a lamb. 150 Mr. A.

Saundersi, Stebbing, with which this species may be identical *. ‘lhe two large males mentioned above, however, show such a marked difference in the great development of the meral joints of the last three pairs of pereeopods, that at first sight I took them for a distinct species. As, however, they were associated with the smaller form, with which they agree in the rest of their structure, I have no doubt that they are only full-grown males. It may be remembered that in the adult male of our own Orchestia littorea (Mont.) we have asimilar enlargement of the meral joint in the last pair of perseopods. XXIV.—Description of a new Cyprinodont Fish of the Genus Jenynsia from Argentina. By C. Tare Regan, B.A. Jenynsia maculata. Depth of body 3} to 4 in the length, length of head 32 to 4. -Snout as long as or shorter than eye, the diameter of which is 3} to 4 in the length of head, interorbital width 2 to 21. Body regularly and completely scaled; 28 to 30 scales in a longitudinal series. Dorsal 8-9; origin equi- distant from extremity of operculum and base of caudal or from eye and end of caudal. Anal 8-9, opposite to the dorsal ( ¢ ) or a little in advance of it (¢). Caudal rounded or subtruncate. Pectoral about 3? the length of head; ventrals extending to the vent.

Pub- lished under the authority of the Secretary of State for India in Council. Edited by Lt.-Col. C. T. Bryenam. — Rhynchota. Vol. ILL. (Heteroptera — Homoptera). By W. L. Disranr. London; Taylor & Francis. Pp. xiv, 503; text-figs. 266. Cot. Bryenam has prefixed a preface to this volume (the first published under his editorship) expressing the general regret felt at the death of Dr. Blanford, the originator of the series of works on the Fauna of British India, and noticing the arrangements made for future volumes, comprising works on Coleoptera, Lepidoptera, and Mollusca. The present volume contains the conclusion (families 17 to 24) of the Heteroptera, chiefly including the not very extensive but ex- tremely interesting Water-Bugs, and the first two families of Homoptera—the Cicadidee (three subfamilies) and Fulgoride (twelve subfamilies), It will thus be seen that the largest, and in the case of the Homoptera the handsomest and most conspicuous, species fall into the present volume. ‘These sections are, however, very poorly represented in Britain. Of the great and vociferous family Cicadidie we have only a single rare and local representative, and even this one of the smaller species, measuring under 2 inches in expanse, though from 5 to 6 or even 7 inches is no uncommon size in India and other warm countries. Even so, however, our own species is the largest British species of its order, except the curious aquatic Ranatra belonging to the Heteroptera. The Water-Bugs and Fulgoride are somewhat better represented in Britain, but the latter only by comparatively small and insignificant species, whereas the Indian Fulgoride are as large and brightly coloured as butterflies and tiger-moths, which, indeed, some of the species resemble, while others are remarkable for the large and often curiously shaped protuberance on the head, which, however, finds its greatest deve- lopment not in an Indian species, but in the large South-American lantern-fly, which sometimes measures nearly 6 inches across the wings. It is curious that both the South-American lantern-flies and the East-Indian candle-flies should be reputed luminous, and yet that modern entomologists should not have been able to confirm the statement in either one case or the other. We hope that the high standard of excellence which the ‘ Fauna of British India’ has exhibited since its commencement will be maintained permanently by the combined efforts of editors, authors, and artists. A Synonymic Catalogue of Homoptera—Part I. Cicadide. By W. L. Distant. London: Printed by Order of the Trustees of the British Musenm, 1906. 8yo. Pp. 207. Tuts is one of the familiar brown-covered Catalogues that have been so useful to entomologists since the Trustees of the British Museum decided to adopt that form, instead of the long series of publications 156 Miscellaneous. in a smaller size with blue paper covers which preceded them. The present Catalogue is devoted to the very interesting family of the Cicadide, which includes the largest species of the suborder Homoptera, but which is entirely unrepresented in the British Islands, except by a single rare and local species, found chiefly in the New Forest. - The loud stridulation of many of the foreign species is a great feature of forest life abroad; and even in Greece the Cicada’s “song” has been famous from classical times onwards. Mr. Distant has long been one of the leading authorities on this family, having published a ‘ Monograph of Oriental Cicadide’ as long ago as 1889, and having also included it in the third volume on Rhynchota in the ‘ Fauna of British India,’ published during the present year. The Catalogue before us extends to 188 pages, exclusive of Index, which fills 19 pages in triple columns. The number of genera admitted is 179, and, besides the full synonymy, useful tables are given of the genera in each division. The enormous increase in entomological literature renders the frequent publication of monographs and catalogues (which are as grammars and dictionaries) indispensable to working entomologists ; and we cannot have too many of them, provided they are written by men-well up in their subject and are fairly complete and up to date. Opinions on details differ; but there are three particulars in which we think Mr. Distant’s book might have been improved. First, we think that the species under each genus should have been numbered as well as the genera. Secondly, the species contained in the Natural History Museum should have been marked, and all names the types of which are included in the series should have been specially indicated. Thirdly, we find a list of undetermined species at the end of the book; but we should have preferred to see all these, except those absolutely unrecognizably described without figures, assigned to their probable places, if necessary with a query. In the case of Walker’s species not in the Museum, the types perhaps still exist in other British collections. We do not make these remarks as criticisms, but as suggestions, and have no hesitation in recommending Mr. Distant’s work as absolutely indispensable to all students of the Cicadide. W. F. K.

Ten communications to these ‘ Annals’? upon the Mollusca obtained by the ‘Investigator’ have already appeared—two by the late Professor Wood-Mason and Professor Alcock (1891, vol. vu. pp. 15-19, and vol. vill. pp. 443-448), and eight by the present writer (1894, vol. xiv. pp. 157-174; l. c. pp. 366-368 ; 1895, vol. xvi. pp. 1-19; /. c. pp. 262-265 ; 1896, vol. xviii. pp. 367-375 ; 1899, vol. iv. pp. 237-251; 1904, vol. xiii. pp. 453-473 ; vol. xiv. pp. 1-14). The new and more interesting species have been figured in the above papers or in the “ Illustrations of the Zoology of the Investi- gator,’”’ edited by Prof. Alcock. The species still unfigured and those described in the following pages will eventually be illustrated in the latter work. Of the numerous species now described the most inter- esting, perhaps, is the Morio Alcocki, which may be regarded as an Indian-Ocean representative of the Mediterranean and North-Atlantic M. rugosa. The occurrence of Oocorys sulcata, another Atlantic form, off Ceylon, is also extremely interesting. Other fine shells are Bathybembix Nevilli, Gaza Frederici, ”Dentalium cor nu-bovis, and Nucula (Acila) granu- lata. What is especially noticeable in all these collections is the absence of many new generic types—indeed, up to the Ann. & Mag. N. Hist. Ser. 7. Vol. xviii. 12 158 present only two have been discovered, Mr. E. A. Smith on Mollusca from the namely, Pontio- thauma*, described in 1895, and Manaria, in the present paper. | Station Nos.

The specimens from Station 260 are much ‘larger than any examples which I have seen from Japan, the original locality of this species. The largest is 80 mm. long and 37 broad. Like the specimens mentioned at the above reference all those in the present series have the top of the spire eroded. The operculum is narrow, 17 mm. in length, and has the right margin serrated.

Station 268, S.E. of Cape Comorin, 556-595 fath., green mud and sand. According to Mr. Pace this species should be removed from Pontiothauma, although in many respects it closely agrees with that genus. Pontiothauma minus, sp. n. Testa ovato-fusiformis, alba; anfractus 8 ?, superiores detriti, ceteri supra concavi, infra convexiusculi et costati, costis subangulatis, spiraliter tenuiter lirati lineisque incrementi tenuibus striati, ultimus costis infra medium evanidis, antice contractus ; apertura alba, longit. totius 3 equans ; labrum tenue, supra vix sinuatum ; columella levis, callo albo circumscripto induta ; canalis anterior latus, brevis, subrecurvus. Longit. 30 mm., diam. 14; apertura cum canali 15 longa, 5 lata. Hab. Station 318, off W. of Ceylon, 1085 fath. Another specimen, in worn condition, is rather larger than the type, being 39 mm. in length. The cost in this species are about eighteen in number, somewhat acute, and do not reach to the suture above, but terminate at the depression at the upper part of the whorls. The transverse lire are fine, contiguous, and continuous over and between the costz. Animal without eyes or operculum, and the foot is much flattened behind. Pontiothauma Pace, sp. n. Testa late fusiformis, alba; anfractus 10 ?, superiores detriti, ceteri supra concave declives, in medio leyiter angulati, oblique costati, spiraliter tenuiter lirati lineisque incrementi flexuosis sculpti, ultimus paulo inflatus, antice angustatus; apertura cum canali 1 160 Mr. E.

Longit. 60 mm., diam. 27 ; apertura cum canali 29 longa, 13 lata. Hab. Station 249, S.W. of Cape Comorin, 1022 fath., green mud and Globigerina ooze; also Station 318, off W. of Ceylon, 1085 fath. This species differs from P. mirabile, Smith, in having the whorls angulated in the middle, in the finer spiral lire, more slender coste, &c. The ribs are nineteen in number upon the body-whor] and only slightly developed in the concavity or upper part of the whorls. A specimen from Station 318 has only sixteen coste and the aperture is white within. Animal apparently without eyes or operculum. Named after Mr. 8. Pace, who kindly reported upon the soft parts of the genus Pontiothauma (Journ. Linn. Soc., Zool. 1903, vol. xxviii. pp. 455-462, pl. xli.). Clavatula navarchus (Melvill and Standen).

Station 258, West of Travancore, 102 fath., sand (‘ Investigator’) ; Persian Gulf, 140 fath. (M. & S.). Several specimens rather smaller than the type, now in the British Museum, but otherwise the same. The operculum is rather thick, semioval, having one side straight and the outer margin curved. ‘The nucleus is at the middle of the straight edge, the outer surface being finely concentrically striated and the underside with a raised edge, with some concentric wrinkles in the middle. In general form the shell bears a resemblance to C. bimarginata, Lamarck, and C. diadema, Kiener. Pleurotoma carinata, Gray. Pleurotoma carinata, Gray; Smith, Ann. & Mag. Nat.

Longit. 35 mm., diam. 134; apertura cum canali 18 longa, 6 lata. Hab. Station 331, off Andaman Islands, 569 fath. A single specimen only. The longitudinal costz are very fine, obliquely arcuate above the angle, subnodose at the angulation, and attenuated below, so that they hardly reach to the suture. The labral sinus is very shallow indeed and the shell has a general Beleeform aspect. 162 Mr. E. A. Smith on Mollusca from the Pleurotoma (Surcula) subcorpulenta, Smith. Pleurotoma (Surcula) subcorpulenta, Smith, Ann. & Mag. Nat. Hist. 1894, vol. xiv. p. 161, pl. ili. fig. 6. Hab. Station 321, off S. of Ceylon, 660 fath. Two half-grown specimens, differing from the type in having the cost more numerous and in their rather more slender form. Pleurotoma (Surcula) vepallida, Martens. Leucosyrine vepallida, Martens, Deutsch. Tiefsee-Exped. ‘ Valdivia,’ vol. vii. p. 80, pl. ii. fig. 6. Hab. Station 281, off Coromandel coast, 300 fath.; Gulf of Aden, in very deep water (Martens). One specimen, agreeing in all respects with the type. Said to have no operculum. Pleurotoma (Surcula) Thisbe, sp. n. Testa fusiformis, turrita, sordide albida; anfractus 10?, superiores erosi, ceeteri supra concavyi, in medio convexiusculi, oblique tenuiter plicati, plicis vel costis inferne attenuatis ad suturam vix pro- ductis, lineis incrementi tenuissimis sinuosis sculpti, infra con- cavitatem, supra et infra costas, transversim tenuiter striati, ultimus antice valde contractus, transversim striatus; apertura elongata, antice canaliculata; labrum tenue, ad suturam late et subprofunde sinuatum, in medio arcuatim prominens ; columella curvata, callo tenui levi circumscripto induta. Longit. 44 mm., diam. 14; apertura cum canali 18 longa, in medio 6 lata. Hab. Station 283, off E. of Ceylon, 1086 fath. The chief characteristics of this species, represented by a unique specimen, are the smooth concavity at the upper part of the whorls, exhibiting only very delicate lines of growth and faint traces of spiral striz, the numerous slender oblique coste upon the lower two thirds of each whorl, and the distinct close wavy striz on and between the mbs. These are nineteen in number upon the penultimate volution, thickest at their upper ends, obliquely curved, attenuated below, and only just reach to the suture. The body-whorl, excepting in the concayity above, is delicately wavy striated throughout. Pleurotoma (Surcula) agalma, sp. n. Testa parva, fusiformis, turrita, alba, epidermide tenui grisea induta ; anfractus 11 ?, superiores erosi, ceteri lente accrescentes, supra ad Bay of Bengal and the Arabian Sea. 163 suturam carina tuberculata cincti, in medio angulati, serie nodu- lorum ornati, liris tenuibus spiralibus paucis lineisque incrementi flexuosis sculpti, liris infra angulum minute nodulosis, anfr, ultimus infra peripheriam liris transversis 14-15, partim nodu- losis, cinctus; apertura parva; labrum tenue, supra angulum haud profunde sinuatum, infra arcuatim prominens; columella subrecta, callo tenui induta; canalis brevis. Longit. 18 mm., diam. 6 ; apertura cum canali 6 longa, 2} lata. Hab. Station 269, W. of Cape Comorin, 464 fath., green mud and sand. Only a single example obtained. ‘The lines of growth are rather strong and very flexuous, and on passing the delicate spiral lire, except in the concavity above the angle of the whorls and at the base of the body-whorl, are delicately nodulous. The last volution below the nodose periphery has about fifteen liree, of which about six of the upper ones are nodulous, the rest, around the anterior contracted portion, being simple and thread-like. The tubercles on the angle are about eighteen in number, and the lire above it three or four. Pleurotoma (Surcula) exstructa, Martens. Surcula exstructa,Martens, Deutsch.

Testa angusta, elongata, albida, zonis interruptis fuscis (in anfr. penultimo duabus, in ultimo quatuor) picta, costulis numerosis longitudinalibus exilibus et liris transversis tenuibus decussata, varicibus paucis hic illic instructa; anfractus 9, primus levis, convexus, secundus in medio transversim carinatus, tertius levis, bicarinatus, ceteri convexiusculi, infra suturam marginati, ultimus pone descendens, sed ad labrum breviter ascendens ; apertura elongata, utrinque angustata; labrum extra incrassatum, intus ad marginem tenuiter crenulatum; columella leviter arcuata, callo tenui circumscripto induta. Longit. 26 mm., diam. 9; apertura 13 longa, 3 lata. Hab. Off Port Blair, Andaman Islands, 100 fath. In some respects resembling Metula daphnelloides, Melvill and Standen, from the Gulf of Oman, but larger and more finely sculptured. That species also exhibits variciform swellings at intervals, although they are not referred to in the description. Phos roseutus, Hinds. Phos roseatus, Hinds ; Smith, Ann. & Mag. Nat.

Longit. 173 mm., diam. 74 ; apertura cum labro 73 longa, 4 lata. Hab. Station 244, off west coast of India, 119-124 fath. Somewhat recalling N. eucomista, Melvill and Sykes, from the Andaman Islands (Proc. Malac. Soc. vol. ii. p. 169, pl. xi. fig. 11), but with a longer spire, shorter body-whorl, with the granules closer and squarer, and the margin of the labrum more denticulate. N. ravida, A. Adams, is another allied form, but much more globose. As in many other species of Nassa, the upper row of nodules below the suture are slightly larger than the rest. Nassaria levior, Smith.

Bay of Bengal and the Arabian Sea. 167 The figure of this species in the ‘ Thesaurus’ is very bad, the cost being represented too broad and too few in number. I have a very strong impression that F. rufinodis, Martens %*, is only a variety of this species. Fusus incertus, sp. 0. Testa fusiformis, alba; anfractus 8?, superiores detriti, cteri convexi, costati, costis in anfractu penultimo circiter 13, liris filiformibus confertis undique spiraliter cincti lineisque incre- menti striati, ultimus infra medium contractus, costis antice evanidis; apertura inverse piriformis, cum canali longit. totius + equans ; columella tortuosa, callo levi induta; canalis angus- tus, obliquus, recurvus. Longit. 51 mm., diam, 22; apertura cum canali 25 longa, 9 lata. Hab. Station 317, off W. of Ceylon, 590 fath. A single specimen in dead condition. It somewhat recalls the British Tritonofusus (Siphonorbis) fusiformis (Broderip), except that the body-whorl is produced into a longer rostrum anteriorly. The spiral thread-like lines are very fine and close-set, and occasionally two or three form slightly raised ridges. Three or four such ridges are noticeable on the upper whorls and almost form nodules upon the coste.. The lines of growth are close together, and on crossing the transverse lire give them a minutely crispate appearance. ManaRIa, gen. nov. Testa fusiformis, longitudinaliter costata, periostraco induta ; colu- mella in medio plica unica intrante instructa; Jabrum ad marginem tenue, intus incrassatum et liratum. Operculum unguiforme, corneum. This genus has the general aspect of a costate Tritonofusus, but is distinguished by the fold on the columella and the hrate aperture. Manaria Thurstoni, sp. n. Testa breviter fusiformis, alba, periostraco luteo induta, longitu- dinaliter costata et spiraliter striata; anfractus 9 ?, superiores abrupti, reliqui leviter convexi, sensim accrescentes, ultimus costis 16-17 infra medium evanidis instructus, antice breviter rostratus ; apertura elongata, alba; labrum ad marginem acutum, * Deutsch.

Smith on Mollusca from the intus incrassatum et denticulatum ; columella supra arcuata, infra obliqua, in medio plica unica intrante munita, callo albo induta. Longit. 33 mm., diam. 12°5; apertura cum canali 14 longa, 5 lata. Operculum unguiforme, fusco-corneum. Hab. Station 333, Gulf of Manar, 401 fath. The longitudinal cost are not very thick and do not vary much in stoutness, and they are crossed by the spiral sulci or striz, which are about eight i in number on the penultimate whorl. The periostracum is rather thick and longitudinally striated with the lines of growth. The denticles within the labrum are six or seven in number, and from them faint lire run inwards. The fold on the columella is peculiar and forms a prominence at the middle. It is somewhat oblique, but how far it is continued up the columella I cannot say, as only a single specimen is at hand, and that is too precious to break up. Named in honour of Mr. Edgar Thurston, of the Madras Museum. Trophon (Boreotrophon) planispina, sp. n. Testa fusiformis, alba; spira elongata, turrita; anfractus 10 ?, superiores abrupti, ceeteri supra declives, in medio angulati, infra contracti, longitudinaliter lamellati, lamellis appressis, ad angulum spinas planas sursum inclinatas formantibus ; anfr. ultimus antice rostratus ; apertura alba irregulariter triangularis, cum canali longit. totius 3 subequans; labrum tenue, ad angulum canalicu- latum; columella contorta, supra arcuata, callo tenui induta; canalis haud rectus, leviter recurvus. Longit. 37 mm., diam. 25; apertura cum canali 18 longa, 6 lata. Hab. Station 827, W. of Burmah, 419 fath. Very like 7. car -duelis, Wateone pe off Sydney in 410 fath., but with a longer spire and compressed or flattened spines at the angle of the whorls. The lamelle which form the spines are quite closely appressed to the shell, whereas in carduelis they stand away quite free from the general surface of the whorls. A very similar form, 7. actinophorus, Dall, occurs in the West Indies in 140-248 fath. Murex axicornis, Lamarck, var. Murex avicornis, Lam, ; Smith, Ann. & Mag. Nat. Hist. 1904, vol. xiii. p. 462.

The latter, however, might possibly be concealed if the columellar callus were not broken at that part or had the specimen lived a little longer and so completed the reflection of the callosity. The spiral liree appear to be rather more remote from one another, but this results from the larger size of the specimen.

[Te be continued. } XXVI.— Notes on the Genus Tamarrha, Wkr. [Lee.— Trnerna]. By the Rt. Hon. Lorn Watsinenam, M.A., LL.D., F.R.S. Mr. Buscx (Pr. U.S. Nat. Mus. xxx. 728-30) discusses the genus Tamarrha, Wkr., and quotes a paragraph for which I am responsible (Proc. Zool. Soc Lond. 1897, p. 114). 13* 176 Lord Walsingham—WNotes on I wrote of T. nivosella, Wkr. :—‘‘ At the time [when I had wrongly sunk Tamarrha as a synonym of Psecadia] I had seen only the type of Walker’s other species nivosella, which isa 9.”? Had I used the word ‘ examined” for “ seen’ the meauing of the paragraph would have been more apparent. Mr. Busck is now able to say that T. gelidella, Wkr., is not a Psecadia (as I had supposed), but is congeneric with - the type of Tamarrha, a conclusion which he founds on his study of West-Indian specimens ; and, after admitting the synonymy of his own genus Babaiara, which consequently sinks, he writes it ‘ is evidently the species which Zeller sub- sequently described as Psecadia exornatella.” Zeller described (Hor. Soe. Ent. Ross. xii. pp. 238-40) Psecadia exornata (uot exornatel/a) from two males taken at Chanchamayo, Peru, with which he associated under a separate description two smaller males from Cuba, all in Museum Staudinger. I have a single male from the same Peruvian collection, purchased from Staudinger in 1891, which agrees absolutely with Zeller’s figure and with his first description, and has a smooth head. It seems more than probable that the Cuban specimens are not identical with those from Peru. I have also a female from Jamaica in which the costal shade reaches the base instead of being broken up into spots ; the central band is distinctly continuous with the costal shade, not separated from it, the white patches much more clearly defined and separated from each other; this specimen agrees absolutely with the type of 7. gelidella, Wkr., and is certainly not the Peruvian exornata, Zell. It may be interesting to observe that the locality “ Chanchamayo” is not to be found in maps; the collector Than.m is known to have referred to a valley on the eastern slopes of the Andes; ‘ Dr. Staudinger schreibt mir dariiber: Thamm sammelte in den Cordilleren in einer Hoéhe von 2000-8000’, selten noch héher, am Chanchamayo, einem Nebentluss des sich in den Amazonen- strom ergiessenden Ucayale, unter dem 12 Grad siidlicher Breite” [Z., Hor Soc. Ent. Ross. xiii. 4 (1877)]. “ Chancha- mayo” is said tomean “ Humming- bird? in the local language. Such confusion is not unfrequent among travellers, as when Captain Cook tried to ascertain the native name for a well-known animal and received the answer “* Kangaroo,” signifying “I don’t know what you mean.’ “We now come to Tamarrha niv osella, Wkr., the type of the genus, or, rather, the selected exponent when Tamarrha was revived. paie in describing his Psecadia adustelia, which I have identified as a synonym of nivosella, Wkr., the Genus Tamarrha, Wr. a regarded his species as sexually dimorphic, and pointed out the differences between the ¢ and the ?, especially the greater extent of the grey colouring in the g, which in the ? was cut off by the white costal area above the dorsal patch. Ihave both these from Jamaica, with both sexes of each, and they are distinct species. ‘The less clouded form, of which Zeller had only the ?, is not the same as the ? deseribed by Walker, aud seems nniformly smaller and paler than the other; but there is one point which now enables me to identify without doubt Zellers ¢ adusitella—he specially mentions “ Fiihler beim ¢ mit auffallend verlang- erten.... Wurzelgliede.” This applies to the darker form only, precisely as seen by Zeller, and is most remarkable. Walker’s two 2 9 are undoubtedly this species, of which I have now a @ with the long basal joint, but his ¢ differs in the short basal joint of the antennze as well as in the details of the markings. There are at least three other species, differing very slightly, from Cuba, Jamaica, and Domingo. Zeller’s Portorico females may probably come to be identified with one of these aud possibly with the genus Hwarne, Mschl.+ Saalm. I send these notes at once, since | have no leisure at present to study in further detail the interesting papers on Micro- lepidoptera lately published and kindly sent by Mr. Busck. No one can more highly appreciate the excellent work he is doing ; but it seems a pity that facilities are not afforded to authors of scientific papers published by the American Government for correcting proofs. Had the proofs passed through the author’s hands, such errors as “ Zellar” for “ Zeiler,” “Flore” for ‘ Hore,” ‘‘nievosella” for “ nivo- sella,” “ Hyponementide ” for ‘‘ Hyponomeutide,” &c., &c., would certainly have been avoided: all these and ‘ Ypono- meutide,” to which Z am said to have referred Tamarrha, are on p. 729. If I were wrong in placing the genus Tamarrha in the Hyponomeutidee, additional matenal obliges me to take exception also to associating it with the Gicophoride. Does Mr, Busck know the African genus Gymnogramma aud others with veins 7+8 of the fore wings stalked, or Trichostibas, Zeller, (=§ Penthetria, H. Edw.) ? and would these affect his opinion as to the extent of the Hyponomeutide? I would now rather incline to placing Tamarrha with the Azinide, founded on an Asiatic genus and characterized by the con- tinuation of the discoidal vein direct to vein 8. I cannot conclude without drawing attention to a quotation on p. 733, where the author cites Dr. Dietz’s reference to 178 Lord Walsingham on a new Tineid Moth. “the apparently heretofore overlooked” character, the more or less furcation of “vein 1 6 in the hind wings,” which he finds in several genera of the Tineine. In Tr. Ent. Soc. Lond. 1891, 102, when criticising de Peyerimhofi’s reliance on this character as distinguishing the Tortricide from the Tineide, I remarked that the furcation of vein 16 occurred in a number of Tineid genera, and even in “ Tinea tapetzella, L., itself.” May I suggest that the application of the word “‘ overlooked” is capable of extension, but not in the direction indicated (vide l. c. pl. vii.) ?

When the forewings are denuded transverse striz are observable, between the veins, giving a reticulated appearance. These are due to lines of thickening from which the majority of the highly-developed scales arise; they are almost per- pendicular and extend from costatodorsum. ‘This structure oceurs also in Opogona aurisquamosa, Btl., and in Stagmato- phora (Pyroderces) argyrogrammos, Z.; if not overlooked it is apparently unrecorded. The specimens are broken and in poor condition. The habits of the species are particularly interesting, as being apparently similar to those of Batrachedra Rileyi, Wlsm., discovered in Georgia among rotten cotton-bolls. The similarity in colour and markings between the two insects is so close as to suggest the idea of mimicry (which, in this case, can of course be only synchromatism) ; but the form of the palpi and the breadth of the hind wings, apart from the question of neuration, are at once sufficient to distinguish them and to place them in different genera, Note.——In February last Mr. Walter Draper, of the Government Gardens, Delta Barrage, Egypt, sent to the British Museum some cotton-pods infested with a Hemipterous insect (Oxycarenus hyalinipennis, Costa) and numerous small caterpillars. Lately on looking at the bottle I found a number of small moths, all dead, and mostly with all their scales rubbed off. As Mr. Draper, who discovered this new pest in the cotton, wished to have its name, I sent specimens to Lord Walsingham for determination, and these are the subjects of the foregoing description.—Cuas. O. WATERHOUSE. 180 Mr. G. Lewis on XXVIII.—On new Species of Histeridee and Notices of others. By G. Lewis, F.L.S. TuHIs paper, the twenty-eighth, follows one published last April, and the series as a whole will in a measure serve as a supplement to Marseul’s Monograph of 1853-1864. Marseul established very few genera, less than forty in all, and appa- rently he was reluctant to increase their number, although, had he had more material at his hand, there is little doubt he would have founded others. He would not, for instance, lave associated Phylloma bahiense and corticale, F., or Sternaulua zlindica and Edwardst, Mars., in the same genera if he had known more than a single species of each kind. ‘To-day our knowledge of the family is but a little more advanced, as the Histeridz belong to a class of insects which, being small and of secretive habits, do not come within the observation of general collectors, and they also require special methods of search, as some attach themselves to other insects, such as ants, termites, wood-boring Coleo- ptera, &c. It is a matter for regret that collectors, while over- looking the Histeridze, miss many curious species of Colydiidze and others which are commensal with them; this applies especially to collections made in the tropics. One of the most curious discoveries of recent years is the finding of one of the Saprinini, Chelyoxenus xerobatis, Hubb., which has asymmetrical claws, in the galleries made by a tortoise, Gopherus polyphemus, in Florida, and another of nine or ten species of MJonoplius in the tenements raised by the termite Hodotermes Havilandi, Sh., in 8. Africa. In my recent Catalogue varietal names (Ann. & Mag. Nat. Hist. vol. xvi. p. 340, 1905) appear as part of the synonymy, and I observe with satistaction that the Recorder of the ‘Zoological Record,’ 1904, remarks that “the naming of varieties is at present carried to a great extent, and we have not space to record them all, but we endeavour to point out all that appear to be of real importance.’ Any name reasonably and purposely omitted in the annual register of the ‘ Record’ is practically deleted, and a recognized method of deletion of superfluous names is annually becoming more and more desirable. The Recorder also says: “ It may not be superfluous to add that the study of variation is by no means dependent for advancement on the naming of varieties.” Lioderma patulum.

This species may be added to the faunistic list of Japan; it was found there by the late Mr. J. H. Leech. Norouister, Lewis. Owing to the discovery of more species of this genus, the following additional characters may be given :—The antennal fossettes are a little behind the anterior angles, the forehead has no transverse stria, the deep lateral thoracic sulcus is a very important character and always terminates abruptly at both ends, the apices of the elytra are constantly punctate, and the anterior tibiz are 7-dentate.

When I identified this species as C. guttipes, Walker’s type specimen was in an unset condition ; since then it has been set out, with the result that the Guatemalan specimens are found to constitute a distinct species. C. guttipes, by the colour of the tegmina, is somewhat closely allied to C. stigma, Fabr., but the colour of the dorsal surface of the abdomen (in a somewhat mutilated condition) appears to be ochraceous and unicolorous.

Some confusion appertaining to these genera, as Stal had not given the type of his genus Pecilostola, I sought the assistance of Dr, Aurivillius, who kindly examined the specimens in the Stockholm Museum, and informed me :— “The genus Pecilostola, Stal, is not in onr collection. Under the heading of Hypepa there are, however, three species— costata, Fabr., semivitrea, Stal*, and venosa, Germ. Only the first two of these species agrees with Stal’s description of Hypepa; the third, venosa, agrees, as it seems to me, well with the description of L@cilostola, and was probably the species on which Stal founded that genus.” ‘There seems scarcely a doubt that Dr. Aurivillius has solved the problem, ZEUNASA, gen. nov.

XX X.— Description of anew Species of Mangabey (Cercocebus Hamlyni). By R. I. Pocock, F.L.S., F.Z.8.,- Super- intendent of the Zoological Society’s Gardens. [Plate VII.] Cercocebus Hamlyni, sp. n. (PI. VIL.) Face pale flesh-coloured, with darker and lighter, larger and smaller spots of brown pigment, most plentiful round and below the eyes and on the bare part of the cheek, but absent on the upper and lower lips and on the nose. Upper lids whiter than surrounding skin, with white eyelashes. Iris of eyes olive-brown ; ball of the eye, where visible, white, with brown pigment-spots. Brow-ridge white, with a few pigment-spots. ars flesh-coloured, with a few pigment- spots. Summit of head thickly hairy, the hairs longest along the middle and forming posteriorly a parieto-occipital crest, for the most part blackish to the roots, with greyish tips. In front and at the sides this black crown is sharply detined by the greyish-white hair forming a narrow brow-band and by the hair of the same colour clothing the cheeks and the area behind the ear. The hairs on the cheek forming a long backwardly directed tuft concealing and projecting beyond the lower half of the ear. make it look more like a mole than a shrew. ‘The comparatively normal position of the extra lower unicuspid shows an even more primitive condition than in Myosorex, which is the only other genus of Soricide that has retained this tooth. Surdisorex Nore, sp. 0. Size rather larger than in any known species of Myosorex. Fur close and mole-like, rather coarser than in average Myosorex; hairs of back about 6 mm. in length. General colour above dark bistre with a greenish iridescence ; indi- vidual hairs slaty grey for five-sixths their length, their ends pale brown with darker tips. Under surface similar but rather paler, without line of demarcation. Har-conches absent. Upper sides of hands and feet dark brown ; fore claws very long and powerful, those of the second, third, and fourth digits subequal, about 5°5 mm. in length (measured from the base above) ; pollex with a pointed claw over 2 mm. long ; median hind claws about 2°5-2°8 mm. in length. Tail very short, not twice the length of the hind foot, closely hairy, without longer bristles, dark brown above and below, Skull longer than in any known species of Myosorez, but more slender, the palatal area actually narrower than in the smaller M. Sclater? ta/pinus, though decidedly longer. ‘Teeth much as in Myosorea, but the second upper unicuspid is pro- portionally larger, about one third the size of the first in cross section, and the third is more elongated and nearly touches the large pm*, leaving no space for a fourth unicuspid. Below 16 994 Mr. O. Thomas on new there is a marked difference in the shape and position of the minute extra tooth characteristic of Myosorex. In the latter it is nearly in the centre line of the tooth-row, jammed closely between the two usual unicuspid teeth, its transverse several times greater than its longitudinal diameter, and looking more like a piece of the cingulum of the first unicuspid than a separate tooth. Onthe other hand in Surdisorex the tooth is nearly circular in section, and is placed in a more normal position in the inner angle between the two larger teetl—in fact, almost exactly as in the bat 7rachops.

In some respects the molars of the Abyssinian rats which in 1902 * I assigned with doubt to Pe/omys— “ P.” dembeensis and Llarringtoni—are intermediate between those of Mylomys and Pelomys; but I am now convinced that these animals should not be included in Pelomys, and think they may be provisionally looked upon as aberrant members of Gnomys, the so-called grooving of their upper incisors being hardly worthy of the name, and their molars being very similarly formed to those of that group. In any case the striking rat discovered by Mrs. Holms- Tarn cannot be assigned to any known genus, and needs a special one to be formed for its reception. Mylomys Cuninghamet, sp. n.

XXXIV.—The Morphology of the Madreporaria.—VIIL. The Primary Septa of the Rugosa*, By J. E. DUERDEN, Ph.D., A.R.C.S8.(Lond.), Professor of Zoology, Rhodes University College, Grahamstown, Cape Colony. In the first paper of this series, published in 1902, entitled “The Relationships of the Rugosa (Tetracoralla) to the Living Zoanthex,”’ I confirmed Count de Pourtalés’s observation that the rugose coral Lophophyllum proliferum, E. & H., has six primary septa (protosepta), all equal in size and situated at * The first two parts of this series of papers appeared in the ‘ Johns Hopkins University Circulars,’ vol. xxi. nos. 155 & 157, and were re- printed in the Ann. & Mag. Nat. Hist. ser. 7, vols. ix. & x., May and August 1902; the third and fourth parts appeared in the Ann. & Mag. Nat. Hist. vol. x., November 1902, and vol. x1., February 1903; the fifth and sixth parts in the ‘Biological Bulletin,’ vol. vii., July 1904, and vol. ix., June 1905; the seventh part in the Ann. & Mag. Nat. Hist. vol. xvii., May 1906. The work is being carried out with the assistance of an appropriation from the Carnegie Institution, Washington. I am under great obligations to Prof. Sydney J. Hickson, F.R.S., for seeing the paper through the press in England. Morphology of the Madreporaria. 997 equal distances apart. Also, by means of a series of micro- scopic sections, I established that the subsequent principal septa (metasepta) are added ina bilateral manner within four of the six primary interseptal chambers, the two middle and the two ventro-lateral chambers ; further, that the additions are made at only one region within each chamber, immediately dorsal to the alar or ventro-lateral septum in the case of the middle chambers, and immediately next to the cardinal or ventral directive septum in the ventro-lateral chambers. I then proceeded to show that of all modern Anthozoa the Rugosa find their nearest representatives in the zoanthid actinians. In the Zoanthee the secondary mesenteries (metacnemes) are added bilaterally at one region within each of the primary ventro-lateral intermesenterial chambers or exoceeles, exactly as are the septa in the Rugosa, but no mesenteries are added within the primary middle and dorso- lateral exoceeles. From our knowledge of the relationship of the septa and mesenteries in modern corals, it was assumed that the two cycles of septa of the rugose corals were formed within mesenterial chambers similar to those characteristic of the zoanthids, the principal or larger septa within entocceles and the secondary or smaller septa within exocceles ; hence the former are termed entosepta and the latter exosepta. In the sixth paper of this series, published in 1905, with the subtitle ‘The Fossula in Rugose Corals,” I endeavoured to show, from a series of developmental stages in Streptelasma rectum, Hall, the true nature of the alar fossule, and also that of the eardinal or ventral directive fossula. I demon- strated that the latter fossula is composite in character, at any rate during the early stages; that it is made up of a series of incomplete septa on each side of the ventral directive septum, while the ventral directive septum is itself smaller than the other principal septa. It was suggested that the small ventral directive septum is to be correlated with the presence in the rugose polyp of a ventral siphonoglyph or gonidial groove, similar to that characteristic of modern zoanthid polyps. This interpretation I considered as greatly strengthening the earlier suggestion that the Rugosa are nearly related to the Zoanthee, and expressed it in the following terms (p. 40) : ‘‘ In the absence of the rugose polyp itself, no surer proof of the relationship of the group to the zoanthids could, to my mind, by adduced than that which admits of the correlation of the simple cardinal fossula with a ventral stomodeal groove.” Figures were given (l. ¢. fies. 2-11) showing that in Streptelasma rectum, as in Lopho- phyllum, there are six primary septa, and that the subsequent 228 Prof. J. E. Duerden on the septa are added in the same bilateral manner at four distinct regions, Within the present year, Mr. C. E. Gordon, working in the Paleontological Laboratory of Columbia University, New York, has published a paper, “‘ Studies on Early Stages in Paleozoic Corals” (Amer. Journ. Science, vol. xxi. Feb. 1906), devoted almost exclusively to a discussion of my first contribution. By inverting my figures Gordon shows that the sections of Lophophyllum can be brought into harmony with Kunth’s oft-repeated figure representing the schematic septal plan of a zaphrentoid coral, a fact of which there could be no possibility of dispute. Further, while admitting the hexameral nature of Lophophyllum, he attempts to show that it docs not represent the true primary character of the Rugosa, but is to be explained as a departure from a primary tetramerism, due to acceleration in time of appearance of the thiid pair of septa. Moreover, from his own observations on a decalcified silicified specimen of Streptelasma profundum (Owen), he presents what he considers as evidence in support of a primary tetramerism. He concludes “ that the primitive condition of these [primary] septa in the Rugosa is not yet settled,’ and that exception must be taken to my statement that “studies on the septal development of extinct Paleozoic corals reveal that in these early Sorms the primary septal plan was hexameral like that of mo@rn forms.” These assertions of Gordon are so opposed to what I hold to be the truth with regard to the Rugosa that it becomes necessary to re-open the question. The problem is one of greatest importance if we are to arrive at a proper appreciation of the phylogenic relationships of the Rugosa. Since the appearance of my first paper I have obtained much additional evidence in support of my contentions, and I shall attempt to show that Gordon’s assertions are not warranted by the evidence he submits. In the first place, it must be admitted that the figures of Lopho- phyllum given in 1902 are unsatisfactory, from the fact that the microscopic sections upon which they were founded where not all taken from the same individual coral. Exception might be taken to their representing the actual development of the septa, while the stages depicted are not always those best adapted for illustrating the sequence. In my later investigations I have pursued a different method of study, the results from which are far more reliable than those obtained from the old method of sections. In preparing separate sections much loss of material is entailed, only a few sections can be obtained from any one corallum, and the Morphology of the Madreporaria, 229 individuality of the septa is somewhat uncertain owing to possible loss of orientation. To remedy these defects a method was devised by which, with suitable material, one can follow step by step all the developmental stages from beginning to end without any uncertainty of orientation, and secure drawings of all desirable stages. The process involves the grinding down of an individual fixed corallum from one end to the other, and the study and drawing of all the stages as revealed. The broad end of acorallum is first ground smooth, and fixed by Canada balsam to a glass slide, in the manner usually followed by geologists in preparing micro- scopic sections of rocks; grinding down with fine emery or on a ground-glass plate is then commenced at the opposite end, the narrow tip, and continued all the way. With favourable specimens the septa can be most clearly recognized under a low power of the microscope, and their arrangement outlined by the aid of a camera lucida. The distinctness of the septa can be often emphasized by etching the exposed surface with a little weak acid, and to secure the best reflection of the light from the ground surface while drawing the latter may be smeared with weak glycerine or balsam. By these devices the whole septal development of a simple corallum can be followed almost as satisfactorily as if one had watched its actual growth day by day. It was from such a series that the ten stages representing the septal development of Streptelasma rectum given in the paper on the Fossula were secured, and also the series here reproduced (figs. 1-8), depicting the septal development of Lophephyllum proliferum, and intended to replace those given in 1902. For purposes of the present paper it is not necessary to describe the sections of Lophophyllum at greater length than is given in the explanation to each. They reveal nothing fundamental beyond what was brought forward in the first aper, but a confusion in the latter of main and counter septa, alluded to by Gordon, is corrected. In place of the older terminology I think the time has come to adopt that founded upon more modern knowledge of the relationships of the group and accepted for the Anthozoa geneially. With the exception of unimportant details, the septal sequence of Lophophyllum here given bears the closest relationship to that of Streptelasma rectum in the sixth part of these con- tributions ; moreover, it is that found to be characteristic of a large number of other species of rugose corals which I have studied by the same method (cf. figs. 9-12; 13-16). Septal and mesenterial development is unquestionably one of the most reliable means zoologists possess for determining the 230 Prof. J. E. Duerden on the Fig. 1. Ss id x x SE aE x Fig. Fig. 3.

The lines of calcification of six primary septa (protosepta) are clearly seen, those of the two median septa being continuous. At this level all the septa are thickened to such a degree that there are no interseptal spaces remaining, and in such a surface view as that from which the fizure was taken there is no indication of the boundary surfaces between two adjacent septa. According to the accepted terminology, the upper border is dorsal and the lower ventral. . 2.—Section above that of Fig. 1. An interseptal chamber, repre- sented by the black wedge-shaped areas, now occurs between all the septa. ‘he lines of calcification of an additional pair of septa (metasepta, a, a) are seen, situated within the two middle of the six primary interseptal chambers (the counter quadrants of paleonto- logists).

Fig. 6.—Another septum (ce) oceurs within each middle chamber, and the line of calcification of the dorsal and ventral directive septa (the Gegenseptum or counter septum and the Hauptseptum or cardinal septum) are now discontinuous. The fundamental contention raised by Gordon centres in the number of primary septa characteristic of the Rugosa, that is, whether four or six; and upon this mainly depends 232 Prof. J. E. Duerden on the the possibility of firmly establishing the relationships of the group. ‘The ingrained idea of a primary tetrameral plan for the rugose corals rests upon the fact that in the mature corallite there are frequently four primary septa, which by their greater or less size stand out more or less conspicuously among the rest and divide the calice into quadrants; and, in addition, it is easily seen that new septa are added at four regions, one within each quadrant. As demonstrated in my two earlier papers, these suggestions of tetramerism in both Fig. 7. A further septum (d) occurs within each middle chamber, without a corresponding pair being added within the ventro-lateral chambers, The central part of the dorsal directive septum is beginning to be freed from the inner ends of the other septa, and appears something like a columella, with distinct centres of calcification. In the space between any two adjacent principal septa the first traces of the centres of calcification of the exosepta (2) are now displayed, their appearance all round the calice being nearly simultaneous. The exosepta have thus no ordinal value, such as the principal septa or entosepta possess ; they correspond with alternate external grooves alternating with the principal septa. the developing and mature corallite are not at all proofs of a primary tetramerism ; moreover, Gordon produces no proofs beyond a suggestive condition in Streptelasma profundum to be discussed later. According to my interpretation, in the Rugosa a secondary tetramerism has been impressed upon a primary hevamerism. At first sight it would seem to be a simple matter to determine the number of primary septa in a corallum. It is Morphology of the Madreporaria. 233 rarely, however, that one secures examples of these ancient corals having perfect tips, and otherwise of such a character that the arrangement of the earliest septa can be made out, either from microscopic sections or grinding down. Speci- mens of Lophophyllum proliferum, the species first studied in this connection, are usually remarkably favourable for such an investigation. Where, in other species, the tips are perfect, it is often found that the septa are not determinable until one or more metaseptal pairs have appeared, in addition L ! xz rT x y] The interseptal spaces are now greatly enlarged, and all the septa are free from each other and from the dorsal directive septum with its columella-like free end. Exosepta regularly alternate with the entosepta all round the calice, and the ventral directive septum is a little smaller than the other principal septa, thus giving rise to a fossula. The stage represented is practically that characteristic of the fully developed corallum. to the protosepta ; sometimes partial or entire silicification of the corallum has taken place, and rendered the preparation of sections practically impossible ; while in such as Duncanella borealis the original tip is wanting, and when first collected four, five, or six pairs of septa are frequently exposed to view (fig. 17). Since the publication of my first paper I have made con- siderable efforts to secure from various sources specimens of 234 Prof. J. E. Duerden on the rugose corals particularly adapted for investigating this special problem. The number now available has enabled me to demonstrate the presence of six primary septa in Fig. 9.

Streptelasma rectum, Hall, is a species of which examples are frequently obtained having perfect tips, and the whole corallum preserved in such a way that the septal develop- ment can be followed throughout. All the principal stages have been described and figured in my paper on the Fossula, and in the present connection the fact of supreme interest is that six primary septa occur, all of equal size and situated at equal distances apart (/. ¢. fig. 2).

Manifestly one must be prepared for irregularities in the septal formation of fossil corals just as much as in living corals. Coralla of Cyathaxonia cynodon, HK. & H., are also well adapted for the determination of the number of primary 236 Prof. J. E. Duerden on the septa, as their tips are usually perfect. On grinding down a corallum for a short distance six equal septa are disclosed, radially arranged, and separated by comparatively large equal interspaces. On pages 234-235 four figures are given (figs. 9-12) displaying the early stages in the septal develop- ment of this species, starting as before with a primary hexamerism. In the above and other species, in which the septal con- stitution has been established by the process of grinding, it may be objected that if earlier stages than tliose first repre- sented could be obtained four primary septa might then be disclosed, and the other two would be seen to be but later additions to a tetrameral group; in other words, that the earliest septal stage is not that indicated as such. Were this the case the dorso-lateral pair here regarded as protosepta would be really the first pair of metasepta. Against this reasonable objection it can be affirmed that in all cases as soon as any of the primary septa are determinable they are already six in number, all fully developed, practically equal in size, and radially disposed at equal distances apart. ‘l'wo pairs never appear in advance of a third pair, Moreover, there is never any hint of the third pair being inclined at its origin towards the others, after the manner of develop- ment invariably characteristic of the first and later pairs of metasepta. All the sections representing the appearance of the metasepta indicate that the new septa first arise within the wall of the calice. Their free end is then turned towards the older septum dorsal to them, and as they become larger and extend higher they seem gradually to travel, as it were, along the older septum, until they nearly reach the middle of the calice. The centripetal end then becomes independent of the adjacent septum, and is either free or united in a columellar mass. Thus the metasepta are not truly radial until they are fully formed. ‘These stages are presented by all the metasepta and also exosepta in their devolopment, but, as already stated, they are never represented by any of the first six septa. All the studies on the development of the corallum of recent hexameral corals, conducted by Lacaze- Duthiers, G. von Koch, and myself, indicate that six equal septa are formed simultaneously in a radiate manner, and such would appear to have been the case with the corals of Palzozoic times. Among a large collection of rugose corals lent me for study by the United States National Museum, through the assistance of Prof. C. Schuchert, are several specimens labelled Zaphrentis pusilla, n. sp. ‘Vhese have proved to be Morphology of the Madreporaria, 237 very satisfactory for the present study, having perfect tips and septa clearly displayed. Jour of the early stages are reproduced in figs. 183-16. Here, again, on the earliest appearance of the septa six members are present, equal in size, situated at equal distances apart, and disposed approxi- mately in a radial manner; the metasepta are added at four regions in the manner just described, the newer as they appear being inturned towards the older, Fig. 15.

The general relationships very closely resemble those of the two series already described. In addition to these four very decided cases of hexamerism, secured from several specimens of each species, six primary septa have beendemonstrated in Hadrophyllum glans (White), Hadrophyllum pauciradiatum, E. & H., and Mierocyclus discus, Meek & Worthen, though, largely on account of their squat form, these species are not so well adapted for displaying the entire septal development as those figured.

Morphology of the Madreporaria. 239 arrangement is such as to leave no uncertainty that the primary condition was hexameral, and that the later septa have been added in the same manner as in other forms where the sequence is determinable from the beginning. Such are Streptelasma profundum, Streptelasma wayensis, and Dun- canella borealis (figs. 17-21). It seems unnecessary to multiply examples. Wherever the tip is sufficiently well preserved to display the primary septa they are found to be six in number; in no case has even a suggestion of a primary tetrameral condition been encountered. With all these definite facts available there would seem to be no longer a possibility of any reasonable doubt as to the primary hexamerism of the Rugosa. In his paper Gordon does not attempt to dispute the hexamerism of Lophophyllum proliferum, but endeavours to explain it as the result of the precocious appearance of what, according to him, should be the first pair of metasepta. This pair, here regarded as the primary dorso-lateral pair, Gordon supposes to belong not to the protoseptal, but to the metaseptal series, and owing to its accelerated appearance it gives a false hexameral character to the primary stage. This idea of acceleration is altogether hypothetical, and its author does not produce a single acceptable fact in its support. He considers that a departure from the original _ tetrameral type is likely to occur in a form such as Lopho- phylum which appears in Carboniferous times, that is, towards the close of the geological distribution of the rugosids. This argument, unsatisfactory in itself, now fails altogether in view of the fact that comprised in the list of corals given above, in which six primary septa have been definitely established, there are representatives of almost all ages in the chrono- logical extension of the rugose corals. Gordon draws attention to the fact that in the older stages of growth of a corallum there is no difference in character between the dorso-lateral pair of primary septa and the principal septa which arise later, that the interseptal spaces between these septa and the adjacent septa differ in no ways from the other interspaces, and that exosepta appear in the dorso-lateral primary interseptal spaces just as in others. Werte these really primary septa he expects that they would present some feature distinguishing them from the later principal septa. Such an expectancy, however, is altogether contrary to what we actually know of development and growth in the Anthozoa. All studies in this group, particularly among the actinians and corals, reveal that the growth tendency is everywhere towards a perfectly cyclic plan, with all the parts 240 Prof. J. E. Duerden on the in any cycle alike in size and other characters; however strongly bilateral or otherwise varied may be tlhe course of development, the final result is an approximation towards radial symmetry, such as is characteristic of most sessile organisms where the environmental forces act equally all round. Most rugose corals have an almost perfect cyclic plan in the uppermost part of the calice, though we know that this is founded upon decidedly bilateral developmental stages ; likewise the cyclic disposition of the organs in the adult stages of nearly all actinians and corals gives scarcely any hint of their strongly bilateral developmental sequence. Hence any argument as to the primary or development relationships of the septa founded upon adult appearances has little or no value. Gordon errs with Kunth and others in assuming that each of the external grooves on the surface of a rugose corallum represents a septum formed in orderly sequence within each quadrant (see Gordon’s fig. 15). As a matter of fact only alternate grooves correspond with principal septa (entosepta), and it is these alone which have any sequence value. This is manifest from the series of sections represented in figs. 1-8. In figs. 1-6 only entosepta are yet present, and correspond with alternate external grooves, while figs. 7 and 8 show that the smaller septa (exosepta) arise almost simultaneously at a rather late developmental stage, and are thus of no significance as regards septal sequence. Attention may now be directed to the proof which Gordon has to offer in support of his contention that the primary septal plan of the rugosids is tetrameral. He fully recognizes the difficulties attendant upon securing sections through the tips of the coralla, and apparently has not succeeded in obtaining such; for the only evidence he adduces rests upon a couple of decalcified silicified specimens of Streptelasma profundum, one of which was broken during examination ; with such material study must necessarily be limited to surface views. He states that “of the four primary septa represented in the drawing [J. c. fig. 16], the counter septa extended farthest down, the cardinal next, and the alar next,” and claims that these four septa extended farthest down into the base of the calice and are the only true primary members. I likewise have in my possession about a dozen decalcified specimens of S. profundum, of all sizes, which present all the appearances described by Gordon, and in some the earlier stages are more completely preserved than Gordon’s figures and remarks indicate his two examples to be. 1 have already Morphology of in. Madreporaria. 241 figured the septal plan of one of these young forms (Biol. Bull., June 1905, p. 39). The figure shows that in this particular specimen the details of the early septal growth are so well preserved as to display the septa turned towards one another in the regular manner revealed by serial sections, but suc! are not indicated in Gordon’s drawings; the exo- septa can also be seen in their initial relationships with the entosepta, which is likewise not the case in Gordon’s example. Gordon himself suggests that absorption has taken place in the lower parts of the septa of his specimen, and in the case of the tertiary septa (eosepta of the present paper) acknow- ledges (p. 124) that ‘‘it was impossible in all cases to tell to what length they extended down into the coral.” His own figure and statements would prove that even the primary septa were not all formed at the same time, though such is certainly the evidence from all well-preserved material of other species. ‘Taking into account all the details which Gordon offers, and studying along with them my own much better series of the same species of coral, I am convinced that little or no value can be placed upon his specimen as an aid in solving the present problem. Moreover, I consider that the evidence from none of my specimens could be regarded as conclusive as far as concerns the number of primary septa; to a certain extent the actual details would for ever remain a matter of individual interpretation. Assistance from decalcified silicified specimens must, in my opinion, always be unsatisfactory, largely on account of possible imperfect silicification of the earliest stages. ‘The details obtainable from sections or grinding of the actual tip afford by far more convincing evidence, and manifestly, from the additional evidence produced in this paper, there is no occasion for any uncertainty in the matter; there can now be no reasonable doubt that the hexameral plan is that characteristic of the group. To sum up, Gordon, in my opinion, (1) has failed to pro- duce any evidence in favour of a primary tetrameral plan in the rugosids, and (2) his attempt to explain the hexameral character of Lophophyllum proliferum as resulting from precocity of the first metaseptal pairs is altogether unsup- ported by facts. The demonstration of six primary septa in many other species is proof beyond doubt that L. proliferum is not exceptional in its hexamerism, but conforms to the rugosid type. Gordon is not in a position to discuss the view that the Rugosa find their nearest modern representatives’ in the Zoantheze. One of the necessary arguments for the main- 243 Dr. F. C. Wellman on tenance of this is the establishment of their primary hexa- merism, and unless very weighty evidence to the contrary should be forthcoming this must now be regarded as accomplished. ‘lhe facts in support of the relationship may be summarized as follows :— 1. The Rugose corals and the Zoanthid actinians have both a primary hexamerism. 2. The septa in the Rugosa and the mesenteries in the Zoanthez are added in bilateral pairs at only one region, a vertical zone within the primary exoceeles, there being four such regions—middle and ventro-lateral chambers—in the Rugosa, and two—ventro-lateral chambers—in the Zoanthee. 3. The septa in the Rugosa and the mesenteries in the Zoanthee are never polycyclic, as in modern corals and ordinary actinians ; at most there are only two cycles of septa, large entosepta and small exosepta, disposed in such a manner as could only have been produced in polyps with a mesenterial arrangement similar to that of the Zoantheex. 4. The presence of a ventral directive fossula in the Rugosa, usually persisting in the fully developed and other- wise perfectly radial calice, can be explained by the occurrence within the living rugose polyp of a single ventral siphonoglyph or gonidial groove, such as is characteristic of zoauthid polyps. XXXV.—Notes on the Habits of Tsetse-flies. By F. Cret@Hton WELLMAN, Benguella, West Africa. HAvinG recently had opportunity to make some observations on tsetse-flies in the Esupua “ fly- belt,” about thirty-five miles inland from the seaport town of Benguella, West Africa, L present here some of my findings. Our knowledge of these flies is as yet very far from complete, and first-band observa- tions, including mention of the date, habitat, and species studied, should be recorded. The following notes were a few of them made in November 1904, but most of them date from October 28th and 29th and November 9th and 10th, 1905. The Esupua “ fly-belt” is, as I have said, about thirty-five miles inland from the port of Benguella (13° 8S. on the west coast of Africa) and twenty miles from the city of Catumbella. The fly studied by me is a subspecies of Glosstna palpalis, Robineau-Desvoidy, which the Ilabits of Tsetse-flies. 243 was last year described in the Ann. & Mag. Nat. Hist. as Glossina palpalis Wellmani, Austen (1905) *, Although the district in which the flies were taken was found to contain some game, including eland (Oreas canna Livingstonei), roan antelope (//ippotragus equinus), kudu (Strepsiceros kudu), the duyker (Cephalolophus Grimm?) , and Speke’s tragelaph (Limnotragus Speket), yet I believe that human blood forms the greater part of their food. This is undoubtedly true over at least a part of the “belt.” Along the north bank of the lower Katumbela River from Esupua to a point half a day’s march up the river lies the great Benguella caravan-route, near which there is little or no game, but over which constantly pass great caravans of half- naked Bantus. At Esupua one may see half a dozen of these large caravans camping in one place. It is here that the flies are the most plentiful. ‘They hide in the tall grass and sedges near the river, and also on stones, trunks of trees and vines, and among the leaves of shrubs and bushes on the bank. When a native is sent to the river for water the flies rise from their resting-places as he passes and follow him, seeking for an opportunity to bite. On several different occasions I followed natives going to the river to fetch water, One of these I saw bitten twice, three were bitten once each, and seven I did not see bitten at all. The Bantus say that the bite is painful, and I noticed that if a fly settled on a porter’s back the man generally slapped himself as it began to insert its proboscis. Some of the specimens I took had abdomens greatly distended with biood. The flies do not always remain so close to the river. ‘The first one I saw in November 104 was between three and four hundred yards from the river in thin ‘ desert” bush, consisting of Acacia refeciens and other thorny shrubs, which afford practically no shade. Gl. palpalis Wellmani certainly does not share the dislike for human ordure which has been ascribed to its congeners. I have frequently seen it in and around the filthiest native camps at some distance from the river and from shade, where it had evidently gone for the purpose of sucking human blood. ‘The fly bites most viciously during the heat of the day, and, as I have said, goes considerable distances in search of food. It bites less readily in the evening and early morning. The native blacks claim that it occasionally bites at might. ‘The one observation that [ made in view of this statement leads me to suspect that it is * Ser. 7, vol. xv., April 1905, p. 390, 244 Geological Society. not true, at least for the time of year mentioned at the beginning of these notes. All three of my visits to Esupua were made during the heaviest rains of the year, which, according to native reports, do not seem to have the effect which has been claimed for them in reducing the numbers of cc fl rae ia have elsewhere shown that GJ. palpalis Wellmani is a disseminator of human trypanosomiasis, and that this disease is unfortunately on the increase in Benguella District. PROCEEDINGS OF LEARNED SOCIETIES, GEOLOGICAL SOCIETY. April 25th, 1906.—J. E. Marr, Sc.D., F.R.S., Vice-President, in the Chair. The following communications were read :— 1. ‘ Trilobites from Bolivia, collected by Dr. J. W. Evans in 1901-1902.’ By Philip Lake, M.A., F.G.S. Several horizons are represented by these fossils. Two speci- mens of Peltura, probably from the Upper Lingula-Flags, were collected at Cochaiya, about 3 miles north-east of Pata. New species of Symphysurus and T'rinucleus, probably of Arenig age, were found about a mile from Apolo, Province of Caupolican. An indeterminable species of Oyy sia was obtained from the right bank of the River Caca, in the same province. Phacops cf. arbuteus, Dal- manites Puituna, and D, Muecurua were collected in the track from Apolo to San José de Chupiamonas, also in the province of Caupolican. The nodules from which they were derived are probably of Lower Devonian age. Descriptions are given of the new species and other forms mentioned. It is worthy of remark that, while the earlier forms show affinities with the contemporaneous European fauna, the Devonian species are much more closely allied to those of South Africa and North America. 2. *Graptolites from Bolivia, collected by Dr. J. W. Evans in 1901-1902.’ By Ethel M. R. Wood, D.Sc. In black pyritic shales from three localities several specimens of Didymoyraptus were collected : one referable to bifidus, one of the type of affinis, and one of the Nicholsoni-type. Phyllograptus, Glossograptus, Cryptograptus, and Diplograptus were also obtaine }, A pale, silky grey shale shows also rare graptolites, belonging to a species comparable with Climacoyraptus confertus. These forms indicate that both the black and the pale shales belong to horizons in the Upper Arenig rocks (Lower Llanvirn of Hicks).

The single very slender specimen from Station 331, although 80 mm. in length, is only 6 mm. at the broadest diameter. This results from its perfect growth from the very young state, the young shell not being broken as is generally the case in these large Dentalia. “It tapers to a point less than a millimetre broad, and exhibits in the usual position a very fine slit 4 mm. in length. The examples from Station 283 are quite like the original type from off Colombo. Dentalium serrulatum, sp. n.

The distinguishing feature of this species is the peculiar fine serration of the fine riblets, especially those upon the concave curve of the shell. Probably this character would be lost in worn specimens. Judging from the gradual tapering of the shell, 1 do not think it would attain much larger dimensions than those here given. The fine decus- sation of the surface is only observable in well-preserved examples. The riblets number sixty to sixty-six at the larger end and about thirty at the narrow extremity. Only one “of the two specimens exhibits a slight terminal notch, but probably the young shell would have a narrow slit. The curve of shell is different in the two examples at hand, one being straighter than the other. Dentalium cornu-bovis, sp. n.

The sculpture of the two valves in this beautiful species is altogether different, that of the right valve, which is a little flatter than the left, consisting of very delicate and close-set regular lamelle or strize, whilst the left valve has numerous fine radiating riblets, which are minutely squamose through being crossed by the very fine concentric lamelle. The internal riblets, ten in number in each valve, do not reach to the margin, and those of the left valve are a little finer than those of the right. The colour of the valves is also different. The deeper valve is more or less orange-tinted within and without, whereas the right valve is almost white, with only a trace of colour on each side towards the dorsal slopes. Amussium manaricum, sp. 0. Testa fragilis, pellucido-albida, opaco-albo radiata, inaquivalyvis, leviter obliqua, et paulum inzequilateralis, valva sinistra con- vexiuscula, coneentrice tenuiter lamellata, lirisque radiantibus tenuibus plus minus cancellata, valva dextra concentrice lamellata, versus marginem concava; umbones acuti, ad angulum circa 115° convergentes ; liree interne circiter 15, haud ad marginem continu, illis in valva sinistra tenuioribus ; auricule inzequales, anticis paullum majoribus.

The valves are fairly strong up to the ends of the radiating lire, but beyond that point they become very fragile and easily break away. The concentric fine lamellz are very similar in both valves, but the left valve, which is gently convex from the umbo to the opposite margin, also exhibits fine radiating lire. These, however, gradually disappear about the middle of the valve, so that only the upper half of the surface is cancellated. The auricles, of which the ante- rior are a trifle larger than the posterior, exhibit fine lines of growth and a few radiating threads also, excepting the hinder auricle of the right valve, which hardly shows any trace of this radiating sculpture. The frout auricle of the same valve is bounded below by a narrow groove at the byssal sinus. Loripes victorialis (Melvill). Cryptodon victorialis, Melvill, Ann. & Mag. Nat.

Station 328, S. of Lower Burmah, 61 fath. The two specimens from the above lozality and those already recorded in the ‘ Annals’ are not quite identical with Deshayes’s type. They have a few more ribs, the sulci between them are not quite so deep, and the nodules on the cost are closer together. However, I am of opinion that a more extended series of specimens would show that these differences were not of specific value. Crassatellistes omanensis, sp. 0.

Tue material available to me for examination in the collec- tion of the Natural History Museum amounts to about 150 specimens (skins and skulls) from some 30 localities. Though Africa north of the Equator is very poorly repre- sented, yet, at first sight, the total material seems sufficient for a fairly exhaustive classification ; but, on careful com- parison, I am convinced that this is not so, and that the area south of the Zambesi, which is especially well represented by series from many different localities, is just that in which the results I have obtained are the furthest from finality. All but two species of the genus have the anterior molar in the lower jaw composed of four laminz or their equiva- Jents. Setting aside for the moment these two aberrant forms as Section III., the genus may be easily further divided into two sections, according as the lower incisors are smooth (or but faintly grooved), or are markedly grooved ; and each of these Sections falls again naturally into two groups. In Section I., comprising the forms with smooth lower incisors, those in which the posterior molar in the upper jaw is composed of four lamin (or their equivalents) and large bulle form the Brantst group, and those in which m* is composed of five Jaminze and the bull are quite small form the unisulcatus group. In Section I]., comprising the forms with grooved lower incisors, those with a single groove as in irroratus, Brants, are readily separated from those with a double groove as in Jacksoni, Thos. The geographical distribution fairly closely agrees with these main divisions of the genus. Thus Section I. is found in a strip of country running across 8. Africa between 28° and 32° 8. lat. Of Section II. the Jacksoni group is found the Genus Otomys. 265 north of the Equator, while the irroratus group inhabits the whole eastern half of the continent from Cape Town to the Equator, the forms south of the Zambesi showing normally six laminz in m*, with about 5 per cent. of exceptional individuals having seven laminze, while those north of that river show exactly the reverse. ‘The western half of Africa is unfortunately unrepresented in the collection, so far as Section IL. is concerned, except by a single specimen from Angola and askull from the Cameroons, both showing seven laminee in m’. This would seem to show that the rule of seven laminze in m’ in the northern forms holds good also of the west coast. But the Angola specimen probably reached that country vid the Congo Valley (the common Otomys of Angola seems to be the aberrant Anchiete of Bocage), and therefore is no indication of the truly indigenous fauna of western South Africa. I arrange the forms I have been able to distinguish in a key as follows :— Key. A. m, composed of four lamine or their equivalents, a‘.

The exact structure of the molars of Ofomys has never, I believe, been worked out. It is not, therefore, certain whether the modified portion of m, in this Section represents one or two laminze ; but in view of the almost universal presence of four lamin in m, throughout the rest of the genus, and the fact that Sloggetli, which undoubtedly belongs to this Section, has four complete lamine in that tooth, I have accepted the proba- bility that the modified area represents two laminz. This modification takes two forms, which, in well-marked cases, are quite distinct and cannot have been produced the one from the other by wear. In both forms the inner ends of the two anterior lamine are produced in a curve, the ante- rior backward and the posterior forwards, and fused into one continuous strip of enamel in the shape of a horseshoe with the open end outwards. In what I have called the “ kidney ”’- shaped form the two free ends of the horseshoe are doubled inwards, showing a heart-shaped or kidney- shaped pattern ; in the ‘spiral ”’ form the free end of the posterior lamina is not or scarcely produced, while that of the anterior is produced boldly inwards and again doubled on itself, thus showing a distinct spiral pattern. These forms of modification, though one form is found in a large majority of individuals of a given species or subspecies, are not quite constant, and I have therefore uot relied upon them in my key.

The type is very young and immature, and although it seems In some respects to ‘resemble suspiciously the eastern form, still, all things considered, I am constrained to agree with and follow Thomas (P. Z. S. 1904, vol. 1. p. 178) in 268 Mr. R. C. Wroughton on accepting the Namaqualand series as quoted above as topo- types of true Brantsi. From this series I deduce the following as normal dimen- sions of this species :— Head and body 150 mm.; tail 100; hind foot 28; ear 17. Skull: greatest length 38; basilar length 31; zygomatic breadth 20; length of upper molar series 8; bull 11. Smith describes the colour as “. . . . sienna-yellow varie- gated with black or umber-brown”’—a fairly exact description, only that the sienna-yellow fades to white except in the central dorsal area, 7. €. in a band, from the nose to the base of the tail, about as wide as the ears are apart. The indi- vidual hairs are all slate-coloured basally, the majority being broadly tipped paler; this pale tip is white except in the central dorsal line, where it is tinged with brown; the minority are black-tipped. The belly, as stated by Smith, is pale grey. All the individuals from Klipfontein, without exception, show the modification in the “spiral” pattern of the two anterior laminze of m,, as also does 7646, the second of Smith’s specimens. On the other hand, Smith’s specimen 158 a (skull 764.c), selected by Mr. Thomas (J. ¢. supra) as the type, shows a modified form in which the inner end of the anterior lamina is produced into the “ spiral” form, but the inner end of the penultimate lamina is also slightly produced and doubled inwards as in the “ kidney” pattern. One specimen only (98. 9.6.1, received from the Cape Town Museum, and labelled “ Namaqualand’) shows a distinct “‘ kidney ” pattern. Both Brantsi and its subspecies luteolus, forming group 1 of this Section, are easily distinguishable from group 2 by the huge bullz and m’* composed of the equivalents of only four laminee.

Deelfontein, C.C. (Col. Sloggett). This form differs from true Brantsi in its darker, more brownish fulvous colouring (the whole upperside being tinged with brown, and not only a dorsal band as in Brantsi, and the brown is much darker than in that species), shorter hind foot, and shorter upper molar series, the Genus Otomys. 269 The following may be taken as normal dimensions for this species :— Head and body 145 mm.; tail 80; hind foot 25; ear 17. Skull: greatest length 38; basilar length 30; zygomatic breadth 20; length of upper molar series 7; bull 11. In all the individuals of this subspecies, quoted above, the modification of the first two laminz of the anterior lower molar shows distinctly the “ spiral” pattern. (3) Otomys unisulcatus. Otomys unisulcatus, Cuvier, Mamm. 1829, pl. cclxiv. 41.805, 41.806 (skull 59.5.7.2). S. Africa (Dr. A. Smith). There is unfortunately no really satisfactory specimen of unisulcatus in the Natural History Museum collection. It is probable that the above are the specimens on which Dr. Smith based his description of unisuleatus (Zool. 8S. A. pl. xxiii.). Basing on these and on this description, the following may be taken as normal dimensions of this species :— Head and body 175 mm. ; tail 90; hind foot 25; ear (no data). Skull: greatest length 38; basilar length 30; zygomatic breadth 21 ; length of upper molar series 8. The shorter tail and hind foot and a-much warmer colouring seem to be the chief characters distinguishing this species from wnisulcatus Broomi, while its larger size and much shorter tail differentiate it from unisulcatus Granti. m*® (in this and the following members of this group) is composed of three complete laminz and a posterior portion in the shape of a trefoil ; in wnisulcatus the modified anterior portion of m, shows a “ kidney ”-shaped pattern.

(Rudd Exploration.) The normal dimensions for this species are :— Head and body 160 mm.; tail 105 ; hind foot 28; ear 24. Skull: greatest length 38; basilar length 31; zygomatic breadth 18 ; length of upper molar series 8; bull 8. This form differs from typical wnisulcatus by its paler, less rufous colouring and its rather larger hind foot, ears, and 270 Mr. R. C. Wroughton on bulle, and from unisulcatus Granti in addition it differs by its larger size. The modification of m, shows a close approximation to the spiral pattern even in the younger specimens. m* is quite as in wnisulcatus. Mr. Thomas described this form as a distinct species, but I do not think it should rank as more than a subspecies ot unisulcatus, to which it is quite as closely related as Granti.

The type is a very old male; more normal dimensions than those given by Mr. Thomas are as follows :— Head and body 105 mm.; tail 100; hind foot 25; ear 22. Skull: greatest length 37; basilar length 30; zygomatic breadth 19; length of upper molar series 8; bull 7°5. The only well-marked character distinguishing this local race from true wnisulcatus is the obsolescence of the grooves on the upper incisors, and therefore the Fish-River specimen must be placed here. The modification of the anterior portion of the first lower molar in the younger specimens shows the “ kidney ” pattern, but in older specimens it seems to approximate to the spiral pattern owing to wear. The third upper molar is quite as in unisulcatus—i. e. is composed of three distinct lamine and a posterior portion in the form of a trefoil. (6) Otomys Sloggetii. Otomys Slogetti, Thos. Ann. & Mag.

The following are normal dimensions for this well-marked species :-— Head and body 135 mm.; tail 65; hind foot 22; ear 19. Skull: greatest length 35; basilar length 28; zygomatic breadth 18; length of upper molar series 7°5 ; bulle 8. This species, though evidently very closely related to unisulcatus, is easily differentiated by its small size, short the Genus Otomys. page | weak tail, the presence of faint grooves on the lower incisors, &e. m, is composed of four complete laminz, while m* is quite the same as that tooth in unisulcatus. Secrion II. The forms of this Section are easily distinguished from those of the last by the grooving of the lower incisors, and the two groups of the section from one another by the character of this grooving. Group 1, with forms which have only one deep groove in the lower incisors, comprises the larger number of the individualsin the genus. As usual in the classification of the mammal fauna of 8S. Africa, the species (trroratus) representing Group 1 can be broadly divided into two forms inhabiting opposite sides of the Zambesi River. Individuals from localities south of the river are found to have an m* made up of six lamine, but in about 5 per cent. of the specimens in the Natural History Museum are found seven lamine; in specimens from north of the Zambesi exactly the converse is found to be the case, except only in the case of the very high-level form from Mount Kenya, which at the northern limit of the species has uniformly six laminz, and the Ruwenzori form Denti, which has only five. Some such geographical division of the species is also indicated by the colouring, the southern forms being black speckled with white, while the northern sub- stitute a brown for the white of the southern forms. It is in dealing with the 8.-Zambesi form of irroratus that I have found that, notwithstanding the very considerable quantity of material available for examination, it is all too small for any really satisfactory result to be arrived at. So far as skull-characters go, the whole species seems to be in an unstable condition. I have failed to find in the southern specimens a single series in which any one distinctive character is really constant. I have already said that the lamine composition of m* presents exceptions to an other- wise general rule. In size there is similar variation: specimens (quite mature) from Cape Town, De Kaap, Trans- vaal, &c., show a greatest skull-length of 36 mm.; others, from King William’s Town, Kuruman, &c., show 44 and even 46 mm.; while the normal size is 40-41 mm. Similar in-and-out variation could be shown for almost any character. Under the circumstances I have decided to leave all these forms under irroratus, only distinguishing, south of the Zambesi, a couple of colour-forms as subspecies. 242 Mr. R. C.

Brants’ description is a long one, but does not furnish any strikingly characteristic characters, and gives no type locality.

Allowing for the exaggerated measure- ments (according to the method of taking these measurements at the present day) of the head and body, the following may be taken as normal dimensions of irroratus :— Head and body 180 mm. ; tail 100; hind foot 29; ear 23. Skull: greatest length 41; basilar length 32; zygomatic breadth 20; length of upper molar series 9; bullz 7.

Unfortunately the dimensions were not recorded by the collector and the skulls are much broken, but the following may be accepted as the dimensions of the species :— Head and body 175 mm. ; tail 90; hind foot 30; ear 21. Skull: greatest length 42; basilar length 34; zygomatic breadth 20; length of upper molar series 9; bull 7°5. The size is much as in typical irroratus, but the warm northern colouring distinguishes it markedly from this species ; the southern form cupreus which resembles it in colouring is much smaller. From its more immediate neighbours it may be distinguished, from nyzke by the shorter hind foot, much broader, flatter, nasals, and the much smaller bullz of that species, and from ¢ropicalis, which it resembles in size and length of hind foot, by its narrower, stouter skull, rather wider, compressed nasals, and rather larger bulle.

Thomas in his description quotes from the collector’s label 195 and 93, for the head and body and tail measure- ments respectively, but I am confident there is some error in these. It is, in fact, a rather short-tailed Otomys of about the size of typical aroratus, and I therefore give as normal dimensions of this species :— the Genus Otomys. 275 Head and body 180 mm. ; tail 80; hind foot 30; ear 23. Skull: greatest length 44 ; basilar length 35 ; zygomatic breadth 22; length of upper molar series 9; bullee 7°5. In addition to the characters recorded by Mr. Thomas, a subterminal compression of the nasals is most marked, and with the generally narrower nasals serves to distinguish tropicalis from angoniensis at a glance. The Mianzini series shows this compression of the nasals very strongly, and the brain-case is even broader and deeper than in the specimens from Mt. Kenya; but the skins seem to belong to a much smaller animal and, moreover, vary a good deal in colour. No measurements, however, were recorded by the collector ; I therefore reluctantly place them under this species. (12) Otomys irroratus Denti. Otomys Denti, Thos. Ann. & Mag. Nat.

The presence of only five laminze in m’ is sufficient to distinguish this from any other member of the northern group or, indeed, of Section II. Mr. Thomas has described this form as a species, but as I have ranked all the other forms as subspecies of irroratus I feel it more convenient to treat Denti in the same way, notwithstanding the lamin formula of m’.

Skull: greatest length 41; basilar length 34; zygomatic breadth 20; length of upper molar series 9; bulle 7. The extraordinarily broad, flat, spatulate nasals serve to separate at once this from all other forms. (15) Otomys typus. Oreomys typus, Heuglin, Reis. N.Ost.-Afr. ii. 1877, p. 76.

When describing his Degenit, Thomas seems to have had some doubt that it was identical with Otomys typus of Heuglin: more recently the receipt of the type skull from the Stuttgart Museum for examination has confirmed this doubt. The dimensions recorded by Mr. Thomas for Degeni are :— Head and body 160mm. ; tail90; hind foot 28-5; ear 22. Skull: greatest length 38; zygomatic breadth 19:7 ; length of upper molar series 9°5 ;_bullee (absent).

The two aberrant species in this Section seem to be found isolated in the midst of normal forms: /aminatus has been taken only from Sibudeni, Zululand (and, it is stated, from a locality in Pondoland), and we have quite normal irroratus from the same place; Anchiete is recorded by Bocage from Caconda, &c., Angola, and has not been found elsewhere outside Angola ; while we have a specimen from Braganza which is apparently a normal irroratus, and Bocage records several other localities in Angola in which irroratus has been found.

Pocock, F.LS., F.Z.S., Superintendent of the Zoological Society’s Gardens. In Trouessart’s Cat. Mamm., Suppl. p. 15 (1904), the described species and subspecies of Cercocebus are referred to two subgeneric groups, Cercocebus (s. s.) and Leptocebus. The latter name appears here for the first time in literature to replace Semnocebus, Gray (nec Lesson), restored by Mr. Lydekker for C albigena, Gray, on the strength of the blackness of the eyelids and the presence of an upstanding crest on the crown of the head. Although considerable latitude in opinion as to what constitutes a generic or sub- generic character must be allowed, there seems to me to be no particular reason for regarding elongation of the hairs on the crown as of higher systematic value than elongation of those on the brow, the cheeks, or the end of the tail, features which, happily, no one has as yet claimed to be more than of specific importance within the group. As for the whiteness of the eyelids, this is most pronounced in the western species (C. lunulatus, ethiopicus, fuliginosus), much less marked, or, according to Mr. Lydekker himself, sometimes absent, in specimens referred to C. Hagenbecki, and also, according to the same author, absent in C. albigena Rothschildi. Moreover, in C. congicus and C. Hamlyni the eyelids are white, and, at least in C. Hamlyn, whiter than the skin of the face. Yet these two species are certainly more nearly related to C. albigena Rothschildi than to any one of the three typically white-eyelidded species. the Genus Cercocebus. 279 It was formerly held, even by authors familiar with C. ful?- gtnosus, that uniformity in the colour of the hair, or, to be accurate, the absence of the subapical pale annuli so common in the hairs of Cercopithecus, was characteristic of the genus Cercocebus, yet in C. fuliginosus there is a patch on the crown of the head due to a broad yellowish area on the hairs of this region; and since the discovery of C. galeritus, C. agilis, and C. chrysogaster, speckled species all three, it has been tacitly admitted that the absence of the speckling has only a specific importance. So far, then, as the colour of the hair and of the eyelids is concerned, a gradation may be traced between the species debarring generic or subgeneric subdivision even on the part of those wishing to attach such weight to the particulars in question; and it appears to me there is just as much or as little reason for regarding the elongated whiskers of C. con- gicus, or the brow-fringe of typical C. albigena, or the long and parted scalp-hairs of C. galeritus as supplying a basis for subgenera as for considering the crown-tuft of C. albigena to have that value. The truth j is, if the genus Cercocebus be divided into subgenera at all, it may with as much justifica- tion be split into three or four as into two. But since no beneficial end is, in my opinion, served by giving subgeneric names to isolated species or groups of species in so small and, comparatively speaking, homogeneous a genus as Cercocebus, and useful names are thereby put out of court for other nomenclatural purposes, I propose to regard Leptocebus as a genuine synonym of Cercocebus *. 1.

Cercocebus, and another, agilis, in Leptocebus ; yet the two names were in all probability applied to specimens only subspecifically distinct from each other. 20* 280 Mr. R. I. Pocock on Loc. Gold Coast. In Trouessart’s Catalogue (1904) and, I believe, in all previous literature this species figured as ethiops, Linn. ; but since, as Mr, de Winton pointed out, this name was originally given to a species of the genus Cercopithecus, it cannot stand for the mangabey in question, for which Junulatus seems to be the correct title. 3.

I have seen a few living specimens of this species, but Mr. Rothschild has kindly afforded me the opportunity of examining the type, which lived for about one year in the Zoological Gardens. ‘This may account for certain discrep- ancies between the description and the specimen. Between the drawing up of the description which was published on Aug. 20th, 1900, and the death of the specimen in February 1901 certain colour-changes must presumably have taken place in the hair, for it is asserted that the speckling disappears on the flanks and outer sides of the limbs, which tend to slate-grey, and that the inner surface of the limbs is rather paler than the outer surface. In the specimen at the present time the flanks and outer sides of the limbs down to the hands and feet are distinctly speckled, though not so strongly as the head and back, and the inner surface of the limbs 1s orange like the lower surface of the head and body, though paler. The describer’s statement’ that this species differs from all other species of Cercocebus as well as from all species of Cercopithecus in the bright orange coloration of the under surface was made in forgettulness of the fact that Pousargues had already ascribed a similar coloration to the belly of the Genus Cercocebus. 281 Cercocebus agilis, and that Cercopithecus Wolf, Grayi, pogo- nius, and nigripes have been known for many years to be so coloured below *. My only reason for commenting now on the fact is the great interest attaching to the similarity in the colouring in the lower parts in all these monkeys, which inhabit, broadly speaking, the same area of tropical West Africa, namely the Congo. There must be an explanation of this, but I am unable to suggest what it may be. 5. Hagenbeck’s Mangabey. Cercocebus Hagenbecki, Lydd. Cercocebus Hagenbecki, Lydekker, Novit. Zool. vii. p. 594 (1900) ; id. op. eit. viii. pl. i. fig. 1 (1901). Loc. Upper Congo: exact area unknown. I am indebted to Mr. Rothschild for the chance of seeing the type of this species. On the forehead, rather less than an inch behind the brow, there is a very conspicuous parting, whence the hairs radiate, those directed forwards forming a conspicuous postsuperciliary fringe. ‘This important feature, attesting close relationship between C. Hagenbecki and C. agilis, is not mentioned in the description and only im- perfectly suggested in the figure. The prevailing colour is a smoky grey above, relieved on the head, whiskers, neck, shoulders, and fore part of the back by the yellowish annula- tion of the hairs. These annuli practically die out on the sides of the body, the outer sides of the legs, and on the tail, which is merely indistinctly speckled in its basal portion above. The throat, chest, belly, and the inner sides of the limbs are dirty greyish white. ‘There is a complete absence in the hair of the brown or fawn or rusty yellow hue men- tioned by the two principal describers of C. agzlis. It is solely on this account that I separate the two forms specifi- cally, although strongly suspecting they will ultimately prove to beat most merely local races (that is to say, subspecies) of one and the same species. But of this there is as yet no proof. According to Mr. Lydekker, the eyelids were black in the living type specimen, whereas another example living in the Gardens at the same time had them flesh-coloured. In the living specimens I have seen they are neither flesh-coloured nor black, but somewhat greyish—that is to say, decidedly darker than in C. ethiopicus, for example. I suspect they are pale in the young and gradually darken with age. * The rufous belly of C. erythrogaster must also be remembered in this connexion. 282 Mr. R. I. Pocock on In the speckling of the coat and the appearance and gradual extension of the yellow of the underside a gradation may be traced in the order named between C. fuliginosus, FHagenbecki, agilis, and chrysogaster, whereas in the direction of growth of the hairs on the head C. chrysogaster resembles C. fuliginosus. 6.

The specimen, now in the Paris Museum, to which Riviére gave the name Cercocebus agilis, without adequate diagnosis, was subsequently deseribed by both Pousargues and Trouessart. I have not seen any specimen which exactly fits the descriptions, though the latter apply pretty closely to mangabeys we commonly receive from the Congo and call CO. Hagenbeckt, 'Vhe arrangement of the hairs on the fore- head is the same and the speckling of the fur also, but the general tint is apparently different in the two; for example, Trouessart says that the hairs of the head and back are more distinctly annulated than those of the sides, so that the tint passes insensibly into fawn-brown (“ fauve-brun”’), then into clear fawn, then into white under the belly. And according to Pousargues the hairs of the upper parts are dark brown (‘‘brun sombre”) and marked on the distal third with two yellowish-green annuli especially distinct upon the head, neck, and arms, much less defined upon the cheek, shoulders, back, sides, and outer face of the legs; the hairs of the chest and belly are scanty and yellowish red at the extremity, but the throat and the inner sides of the arms and legs are silvery grey. The discrepancies between the two descriptions taken by two authors of repute from the same specimen are difficult toreconcile. ‘They are also highly instructive as emphasizing the magnitude of the personal equation to be reckoned with in judging of species from published diagnoses. ‘The reddish- yellow (“jaune roussatre *?) hue of the chest and belly must be very faint, one would imagine, to admit of ‘Trouessart’s failing to detect it and describing the belly as white, unless his examination was made by gas- or candle-light. That Pousargues was probably correct may be inferred from the circumstance that he saw four specimens in addition to the the Genus Cercocebus. 283 type, making a total of two adult males and one adult and two young females, 7.

Sci. Nat. (8) iii. pp. 229-235 (1897). Loc. Brit. E. Africa: Tana River. This species is known to me only from the figure and description published by Peters and from the remarks upon it Matschie and Pousargues have published. The general colour both above and below seems to resemble that of C. agilis ; but the arrangement of the hair on the crown of the head is quite different from that of C. agilis and C. Hagenbecki. Judging from the figure, which, according to Matschie, quoted by Pousargues, is correct, the parting is not, as in those species, a small circular area from which the hair radiates, but almost Y-shaped; the hairs on the forehead turn forwards over the brows and are separated by a transverse parting running from temple to temple from the hairs of the top of the head, which are long and directed outwards from a median longitudinal parting, so that their ends overhang, like a roof, the tops of the ears. The description Pousargues gives of this arrangement does not express at all clearly, in my opinion, what the illustration in Peters’s paper shows. Trouessart’s interpretation is much more in keeping with the figure. But the two species, C. agilis and galeritus, are, I should say, much less nearly related than these French authors believed. 8.

The remaining examples examined and named _ by Mr. Lydekker are in the Natural History Museum, as well as three others received since his paper was written. Two of these three are from Budzi (8000 feet) in Uganda; the third is labelled “ Cameroons,” but this locality is, I think, open to grave suspicion. ‘This specimen is long-coated. The mantle on the nape and shoulders is brown strongly tinged with iron-grey. There is also a considerable quantity of grey in the hair on the fore part of the chest and outer side of the thigh. Except that there is more grey in the coat, this example is very like the type of albzgena, which is young. I believe it represents the adult phase of that species, and Mr. Lydekker has given it the name albigena. In its grey- ness it differs from the two examples from Uganda, in which there is no grey in the brown mantle or on the outer sides of the legs, which are black. One of these specimens is browner than the other and both are rather browner than the type of Johnstoni. Nevertheless I believe the three specimens, which appear to be adult, are representatives of one and the same subspecies. From an examination of all these skins, no two of which are absolutely alike, I am compelled to believe that two, and only two, subspecies are involved, namely a western and an eastern, the former being albigena and the latter Johnstont. Neumann identified the eastern form from Uganda as aterrimus ; but for geographical reasons it appears to me more probable that the type of aterrimus was a young example of albigena. If so, aterrimus falls as a synonym of albigena. If, on the other hand, Neumann is right in his determination, Johnstoni falls as a synonym of aterrimus. It must be borne in mind that Neumann discovered the young of the Uganda form to be uniformly black (Zool. Jahrb. xiii. p. 533, 1900). From this it may be interred that the young of the Congo form (albzgena) is also black. The skins I have seen bear ont this interence. Hence, so far as colour is concerned, the type of aterriémus might be the young or the brown- or grey-mantled race, It cannot, on the Genus Cercocebus. 285 the evidence, be admitted as the ropresentative of a distinct form. 9.

In ‘ Rhynchota Authiopica,’ t. 1. p. 185 (1905), my friend M. Schouteden has placed this species as a synonym of the Pentatoma miniata, Westw., which he figures and enumerates as a var. of Dorycoris pavoninus, Westw. M. Schouteden writes :-—“ D. Rutherfordi est forma nitidissima, marginibus pronoti vix constrictis, a D. miniato tamen, ut videtur, haud distinguenda.” So far from this being the case, the species I described as D. Rutherfordi differs from Schouteden’s figure of D. miniatus (lettered as JD). fuscosus, Germ.) in having the head wholly metallic green, basal half of scutellum metallic blue, and a large transverse spot of the same colour on corium on each side of apex of scutellum, the spot ex- tending for little more than half across the corium. It may be correct to regard D. Rutherfordi as a colour-variety of D. pavoninus, for M. Schouteden has had a large amount of material through his hands, but it is incorrect to refer it to the form he has figured. Subfam. V'esss4raTOMINZE:. KAHLAMBA, gen. nov.

Die Klassif. der Capsiden, p. 8 (1905). The genus Vallerolia was founded and placed in the Saldinz, to which it belongs by possessing only two ocelli, the Leptopinz possessing three. Bergroth, in some miscel- laneous assertions (supra), has strongly declared it to be congeneric with Leptopus, Latr., and Reuter (supra) supports this contention in a footnote to a paper defending and advo- eating his classificatory views on the Capside. As _ the question has a remote Ethiopian interest it may be referred to here. In 1878 Costa described a species as Leptopus assuanensis, which Reuter redescribed as LZ. néloticus in 1881, and Bergroth once more described as L. strigipes in 1891. ‘Both the two latter writers in correcting themselves have sought toadd my Vallerolia Green from Ceylon to the list of synonyms, In describing Vallerolia I gave the ocelli as only two in number, and fearing (after perusing the indictments of Bergroth and Reuter) that 1 might have overlooked a third, I placed the type of the genus under a microscope, and, with these con- ditions, sought the opinion of Mr. E. E. Austen, the well- known dipterist, and of Mr. E. Waterhouse, an experienced British coleopterist, who were also both satisfied that the number of the ocelli was two. It therefore follows that if V. Greent is really the same species as the synonyms of Leptopus asswanensis created by Reuter and Bergroth, it is they who have failed to recognize the proper genus and have placed their synonyms in the wrong subfamily, for Leptopus is known as possessing three ocelli, though neither of my critics has alluded to the number of ocelli inshis svnonymical descriptions.

Ears short, laid forward in the spirit- specimen they barely reach to the tip of the muzzle; their breadth equal to their length ; inner margin strongly convex, outer with a well-marked emargination above, convex below. Tragus as in Dobson’s second group, a small basal lobule present, very much as in A. Smith; inner margin evenly convex, outer slightly concave. Limbs short, less strikingly delicate than usual; upper surface of forearms and proximal part of the digits and of hind limbs and feet clothed with fine golden-brown hairs. Wings to the base of the toes. Poste- rior edge of interfemoral with a fringe of short curved hairs growing from its under surface. Prepuce tufted with long hairs. Fur long, brownish grey above and below, so far as can be made out on a spirit-specimen. Inner upper incisors slender, practically unicuspid, a rudiment of a secondary cusp present about halfway up the hinder aspect ; outer incisors long, nearly as long as the inner ones, each with a minute external basal secondary cusp.

This little Kertvoula is readily distinguishable from any African species hitherto described by its small size, the presence of an interfemoral fringe, and its long outer incisors. Dobson’s K, africana agrees with it in some respects, but is said to have a tragus as in K. //ardwicket and ears “ longer than the head” *. * By this expression Dobson appears always to have meant that the ears when laid forward extended beyond the tip of the muzzle.

CUieands.) yc... Rete a Pe S. 8. centricola, subsp. n. I can find no reason to distinguish Du Chaillu’s S. Nord- hoffi (type B.M. no. 67. 9. 5. 1) from the insular S. Stangeri, though the form occurring further south in Angola seems separable. But with regard to Peters’s S. calliurus, it is to be noted that two specimens from the Como River differ from the series trom the Benito by the larger size of their ante- orbital foramina, which may indicate that the more northern of the two should be separated from the southern; Peters’s name would then apparently apply to the former. With regard to the placing of all these six true Sccuré as geographical forms or subspecies of one species, the links 21s 296 Mr. O. Thomas on between one and another seem to be so complete that I have failed to recognize any division of more than subspecific rank. At first it appeared that at least the dark forms with red feet (eborivorus) might be separated specifically from the straw- coloured ones with yellow feet (Stangeri), but the animal I have named nigeri@ is really practically as yellow as Stangert, while it has the red feet of eborivorus and the white neck-patches of Temminckii. Again, an Eastern Congo specimen has a yellow Stanger? back with red eborivorus feet, but is without white neck-patches. As to distribution, there is as yet no evidence that both Stangert and eborivorus forms occur in any one district, though the ranges of the two types largely overlap. The recognition of Wilsond as a Funisciurus and of Stangert as a true Sciurus is due to Mr. de Winton, who wrote some notes on the group in 1898 *. The following are descriptions of the new subspecies :— Scturus Stangert loande. Size and general characters quite as in true Stangeri, though the yellow of the hinder back is rather more vivid. Head, instead of turning hoary grey on the crown, simply becoming paler and more whitish yellow than the back; a dull yollowish patch behind each ear, and the ears themselves yellow rather than brown. Cheeks whitish or greyish white. Line edging body-hairs along sides of belly well-marked, white. Feet, especially the anterior, more strongly suffused with yellow above. Other characters as in true Stangert. Dimensions of the type (measured in the flesh) :— Head and body 285 mm.; tail 380; hind foot 66; ear 21.

In its yellowish general colour this animal corresponds with true Stanger’, while resembling members of the eborivorus group in its neck-patches and reddish feet. Seiurus Stangeri centricola. Size, as judged by skull, rather less than in true western eborivorus. Colours rich and bright throughout, the fulvous suffusion of the back, often confined in true eborivorus to the rump and never extending beyond the nape, more rufous in tone and carried forward on the head to between the eyes. Line along edge of belly not conspicuous, hoary grey. Yellowish or rutous of limbs at a maximum everywhere, the hind feet especially rich rufous.

Distinguished from other forms of F. pallatus by having black lands and feet. 298 Mr. O. Thomas on Size and general colour as in the darker forms of F. palli- atus, the dorsal colour closely matching that of /. p. ornatus, while the belly is a little darker and richer than in any of them, nearly matching the maroon-red of the tail of F. p. or- natus. Muzzle, forearms, inner sides of hind limbs, and end of tail-hairs all of the same rich maroon-red; but the upper surface of the hands and feet, instead of being also red, are deep glossy black without trace of red, the change at the wrists and ankles being apparently abrupt, though there are microscopic red tips to some of the hairs on the metapodials. Skull and dentition as usual, except that the top of the muzzle is flatter, less bowed downwards, and the molars appear to be rather narrower than in the mainland subspecies.

Collected and presented by J. T. Last, Esq. This squirrel is so abruptly different from any of the forms of F, palliatus by its black instead of red hands and feet that many naturalists would think a binomial should be used for it; but it is so essentially a member of the palliatus group that I preter to regard it as a subspecies, especially as faint indications of red may be found on its feet and also slight traces of black on those of F. p. suahelicus, its nearest relative. In Mr. Oscar Neumann’s account * of the subspecies of F. palliatus he records F. p. suahelicus from Zanzibar ; but if his specimens were really obtained in the island he must have overlooked the very material difference in the coloration of the feet, Mus Brockmani, sp. n. A medium-sized pale grey species, with a very long pencilled tail. Size and general proportions very much as in JM. Ver- reauxt of the Cape. Fur of medium length; the ordinary hais of the back about 9 mm. in length, the isolated longer hairs 12mm. General colour above pale buffy grey, paler than Ridgway’s “ drab-grey,” the light rings to the hairs * SB. Ges. nat. Fr. Berl. 1902, p. 178. African Bats and Rodents. 299 cream-buff. Sides lighter. Belly white, with a sliglit creamy tinge, the hairs along its sides slaty at base, those on the throat, chest, and middle area of belly white to the roots. Kars almost naked, their substance greyish brown. Upper surface of hands and feet pure white; fifth hind toe without claw reaching to the end of the basal phalanx of the fourth. ‘Tail very long, finely scaled (15-16 rings to the em.), thinly haired basally, the hairs lengthening on the terminal half of the tail to form a distinct pencil, of which the individual hairs are about 24 mm. long; in colour the tail is sharply bicolor, brown above and white beneath for its whole length. Skull, as compared with other African medium-sized species, characterized by a rather flatter brain-case than usual, the parietals being less markedly convex; supra- orbital edges rounded anteriorly, square, not ridged, poste- riorly. Palatal foramina widely open, their posterior end not narrowed. Mastoid portion of bulla, as usual in this group, well defined from the sides of the supraoccipital, with a fair- sized vacuity at its upper end.

Ilelogale Macmillani, sp. n. A very finely speckled form allied to H. undulata and A tkinsoni. Size as in the two related species. Fur rather short, the longest hairs of the back barely attaining 13 mm. in length and the shorter ones about 8 mm. General colour above between broccoli-brown and Mars brown, warmer than the former, greyer than the latter; finely ticked with minute buffy specks, terminal or subterminal on the dorsal hairs, the specks far finer than in the allied species and each measuring less than 1 millimetre in length. Under surface near Prout’s brown, with scarcely any speckling, a faintly warmer tinge (Mars brown) on the tips of the hairs. Crown finely ticked Prout’s brown, becoming Mars brown or verging towards russet on the sides of the face, lips, chin, ears, and on areas round and behind the last-named parts. Limbs to wrists and ankles like the body ; upper surface of hands and feet russet, without speckling. ‘Tail speckled bistre, a russet line on the under surface proximally, and a few russet haus mixed with the pencil at the tip.

In dentition it corresponds closely with H, Atkinsoni, and differs equally from the broad-toothed Ll, hirtula, Ictonyx capensis show, subsp. n. Size large, slightly exceeding that of true capensis, there- fore markedly different from the small erythrea, de Wint., of Suakin. General marking normal, the black lines clearly defined, little softened by isolated white hairs or by the tips of the hairs of the white areas overhanging them. Frontal spot of medium size, larger than in true capensis, about an inch long by half an inch broad, running back in a point towards the crown, separated on each side from the post- orbital white mark by about half an inch of pure sharply- defined black. In erythree the median white spot more nearly approaches the lateral ones. Outer white stripes of nape markedly broader than the inner. ‘Tail rather less white than in other subspecies. Skull apparently rather more elongate in general outline than in some of the allied forms. Dimensions of the type (measured in flesh) :— Head and body 395 mm.; tail 298; hind foot 64; ear 30.

Xerus rutilus stephanicus, subsp. n. General characters as in true rutilus, but the grizzled 302 Mr. O. Thomas on new yellowish grey—restricted in that form to the centre of the back—is spread over the whole of the upper surface, so that the pink area along the sides is reduced to a narrow strip, or even occasionally absent, the rufous of the forearms and hips being in such cases isolated from each other. Base of tail coloured like back. Hands slightly suffused with rufous ; feet yellowish white. Dimensions of the type (measured in skin) :— Head and body 215 mm. ; tail 180; hind foot 53.

Collected 18th August, 1905. These ground-squirrels are by no means easy to sort into geographical races, owing partly to their variability and partly to their liability to bleaching, the black parts of the fur bleaching through rufous and fawn to pale sandy, so as to give a wholly different appearance to specimens killed before or after the moult. _ But by a careful comparison of specimens all in fresh fur I find that the series from the Stephanie area differ sufficiently on the average from those representing true rutilus to make a local name advisable, though some examples show evidence of intergradation. The other named forms in this group—brachyotus, dabagalla, intensus, and saturatus— are all further off, both geographically and zoologically, than the true rutilus of Eastern Abyssinia. Otomys typus fortior, subsp. n. By the kindness of Dr. Lampert, of the Stuttgart Museum, I have been entrusted with the loan of the typical skull of Heuglin’s Oreomys typus, and I regret to find that it is after all of the same group as my Otomys Degeni, Heuglin’s descrip- tion of its incisive grooves proving to be grossly inaccurate, Their trae number and positions are as described in O. Degeni, and this latter must, I fear, be regarded as a synonym of O. typus, But the Kaffa form obtained by Mr. Zaphiro, though similar to typus and Degeni in all essential respects, is sutii- ciently larger to make me think it should have a special subspecific 1 name. The skull, as a whole, is markedly larger than that of Degend, which agrees\with what remains of the specimen of typus. ‘lhe worn surface of the upper molars is 8'5 mm. in length, as compared with 7°7 in the other two. ‘he breadth of the two upper incigors, taken together, is 4-7 mm. in fortior, 4:1 in Degent, and 3-7 7 in typus, Mammals from North-east Africa. 303 There is no evidence of any marked difference of age between the three skulls, but, if anything, the type of typus is the oldest of all. In colour the type of fortior is rather browner than that of Degeni, the feet are darker, and the yellowish markings over the eyes and on and behind the ears are practically absent. The following are the general measurements of the type: Head and body 182 mm.; tail 97; hind foot 30; ear 26. Skull: greatest length 39; basilar length 32:2; greatest breadth 19°8 ; palatilar length 18°5; palatal foramina 7:7 ; length of upper molars (crowns) 9°5. Hab. Charada, Kaffa. Alt. 6000!. Type.

General colour along the dorsal area clay-colour, darkened by the minute blackish tips to the hairs. Sides clearer, more nearly “ pinkish buff,” the hairs with whitish subterminal bands. Lower part of muzzle pure white, the same region in mini being more or less buffy. A patch above and behind each eye dull whitish. A white patch behind each ear. Hands and feet white as usual, Soles naked posteriorly, but with a band of short hairs crossing them near the base of the hallux, as in Emdni alone of other gerbilles. T'ail unusually well tufted, with long brownish-black hairs, which attain a length at the tip of about 14 mm.; shorter hairs of tail dull buffy whitish. Skull closely similar to that of 7. Lmdnz, but conspicuously smaller throughout. The posterior palatal vacuities, between the molars, are, however, much narrower than the anterior palatal foramina, while in 7. Hmini they are nearly or quite as broad as the latter. Dimensions of the type (measured in the flesh) :— Head and body 96 mm. ; tail 132 ; hind foot 28; ear 19. Skull: greatest length 30°7; basilar length 22°3; inter. orbital breadth 6; breadth of brain-case 14:2; diastema 8-2 ; palatal foramina 5:2 x 2; length of bulla 9 ; length of upper molar series 4°3.

Hmint, with which 304 Mr. O. Thomas on new it shares the peculiar and hitherto unique character of the hairy band passing across the sole and dividing from each other the smooth posterior part and the distal part at the base of the toes, where the tubercles are situated. From that species, which was discovered at Wadelai by Emin Pasha, it is at once distinguishable by its much smaller size. Named in honour of Col. Sir John Harrington, British Resident in Abyssinia, without whose active assistance Mr. Zaphiro would hardly have been able to carry out his successful collecting-trip. Arvicanthis rea, sp. n. A very large species without dorsal stripe. Size larger than in any other species. General colour of fore-back between hair-brown and smoke-grey, resulting from a coarse mixture of blackish brown and creamy white ; posteriorly the light colour becomes more and more buffy, so that round the base of the tail and on the lower leg it approaches tawny ochraceous. Sides lined cream-buff. Under surface and inner side of limbs white. Forearms dull buffy; hands pale brown; upper side of feet whitish laterally, pale tawny along the middle line. ‘Tail blackish above, dull white on sides and below. Dimensions of the type (measured in the flesh) :— Head and body 212 mm.; tail 175; hind foot 36; ear 22. Hab. Charada Forest, Kaffa. Alt. 6090". Type. Adult male. Original number 101. Collected 30th May, 1905. This is a remarkably fine species, very different from anything hitherto described. Its colour has almost a sugges- tion of silvery blue-grey in it not easy to describe, but very characteristic, while at the same time its unusual size and the entire absence of any trace of a darker dorsal band will distin- guish it from the other members of the group. Unfortunately the skull is missing, but the species is so distinct as to be readily recognizable by its external characters. Lophuromys Zaphiri, sp. n. General colour above greyish, without the warmer tones of the other forms, most nearly matching “ hair-brown” of Ridgway; very finely speckled with buffy. The bases of the hairs deep rufous. Under surface fawn, more or less suffused with buffy. Upper surface of hands and feet dull whitish, ‘ail short, strongly tapering, well haired, markedly bicolor, black above, whitish below, sharply defined laterally. Mammals from North-east Africa. 305 Skull with very widely open palatal foramina. Molars apparently rather broader than usual.

The genus Lophuromys falls readily into two groups of species—the one from Eastern Africa (Abyssinia to Nyasa), with speckled fur, and the other Western (Uganda to the Gold Coast), with unspeckled fur. Whether the forms within each of the groups will be found to intergrade remains to be seen, but for the present I have thought it best to use a binomial term for the Eastern Omo animal. I have named this species in honour of Mr. Ph. C. Zaphiro, the collector, who deserves the greatest credit for his remark- able exploring-trip, of which the series of mammals only forms a small part of the outcome. Lophuromys aquilus brunneus, subsp. n. General colour pale brownish, without the yeilowish tone of L. flavopunctatus, the light rings of the hairs “ clay-colour.” Under surface variable as usual, ranging from pale brown to clay-colour. Hands and feet pale brownish, with or without a central dark metatarsal streak. Tail long as compared with that of Z. flavopunctatus, apparently more as in the East-African aguilus, its colour not so conspicuously bicolor as in flavopunctatus, the under surface only slightly lighter than the upper.

Possibly it may in turn prove to grade northwards into L. flavopunctatus, but all the specimens as yet available have longer tails than that animal. XLII.—Natural History Notes from the RILM.S. Ship ‘Investigator, Capt. T. H. Heming, RN. (retired), com- manding.—Series III., No. 14. Notes on the Skull of the Genus Aulastomatomorpha, with Descriptions of some new Deep-sea Fish. By R. E. Luoyp, M.B., B.Se., Capt. 1.M.S., Surgeon- Naturalist, Marine Survey of India. THE genus Aulastomatomorpha, first described by Alcock from a single specimen (Ann. & Mag. Nat. Hist., Oct. 1890), is unique among the Alepocephalide in possessing a tubular snout with a small terminal mouth. A second specimen of the same species was obtained by the ‘Tnvestigator’ in 1904 from 1100 fathoms off the Arakan coast, and in the following year a new species of this genus was obtained from 1005 fathoms in the Gulf of Oman. Material has been thus obtained for a partial description of the skull of this genus and for a more particular description of the jaw suspensory apparatus, which can be fully elucidated without complete disarticulation and destruction of the specimen. A notable feature in the structure of this skull is the forward position of the quadrate and the consequent prolon- gation of the symplectic and preopercle which articulate with it. The quadrate is a thin fan-shaped bone situated almost entirely in front of the orbit, articulating with the pterygoid and articular in front, and with the symplectic and the pre- opercle behind. The large pterygoid is partially overlapped in front by the small toothless palatine. The mesopterygoid, also a large bone, forms most of the lower floor of the orbit; in front it lies to the inner side of and above the quadrate and pterygoid. The metapterygoid, a small bone, lies on and partially hides the symplectic. The symplectic is of unusual length. The maxilla, which is very loosely connected with the snout, consists of two separate crescentic particles, movable on one another. Skull of the Genus Aulastomatomorpha., 307 The hyomandibular has the usual articulations, ‘The opercular apparatus consists of the usual four bones. The preopercle is much prolonged forward to articulate with the quadrate. The sub- and interopercles are small and linear. The opercle, a very thin triangular bone, bears at its upper end a projecting knob, which is seen externally as a well-marked prominence halfway between the eye and the upper end of the branchial opening. The lower jaw contains articular angular and dentary bones. The upper part of the snout is formed by one long fibrous piece of bone intimately united with the vomer in front and dividing at the base of the snout into two limbs, between which the fore parts of the frontals fit. This long bone repre- sents an ethmoid and two lateral ethmoids; a suture separating these elements could not be found. In the cranium proper the supraoccipital articulates with the frontals and lies between the small parietals, separating them from each other. The frontals are not fused in the middle line.

The premaxillary teeth are fewer in number and are relatively larger ; they are arranged in two sets, an anterior closely set group of eight or nine, and a posterior group of three with wide intervals between. 2. The interorbital space is wider than half the diameter of the eye. 3. The head is covered with a firm smooth skin just as in A. phosphorops, but in the new species the colour of this skin is a dark slaty blue. The colour of the rest of the body is brownish black. ‘The bases of the fins have a blue tinge. The blue colour is partially preserved in spirit. 4, The total height is only § of the total length excluding the caudal fin, but as this specimen is smaller and younger than the type of A. phosphorops, this character does not, perhaps, constitute a specific difference. One damaged specimen, 18 cm. long, from 1005 fathoms in the Gulf of Oman. The wide distribution of the three specimens and the close similarity in the depths from which they were obtained are points worth noting. Species. Depth. Locality.

In all its proportions this species resembles V. pluriserialis very closely. It differs from NV. pluriserialis in the following respects :— 1. The teeth in the maxille are in two series, an outer series of small teeth and an inner series of larger ones. new Deep-sea lish. 309 2. There are only seventy-three scales in the lateral line. 3. The anterior of the two nostrils is relatively larger. The scales of the lateral line are large, measuring as much as } inch in length. The total length of the single specimen is 14 inches. In the middle and hinder parts of the fish, one inch of the lateral line contains six scales, but in the front these scales overlap one another to a much further extent, so that one inch contains eight or nine scales. In the anterior half of each scale of the lateral line is the wide opening of its tube; the margin of this opening is completed in front by a semicircular notch in the hinder edge of the scale which lies next in front. Colour almost black ; head and lining of gill jet-black. One specimen, 14 inches long, from 1005 fathoms in the xulf of Oman. It is notable that N. plurisertalis (Gorm.), which this species resembles in many ways, came from 1010 fathoms in the Gulf of Panama. Raia Philipi, sp. n. The greatest breadth of the disk is equal to the greatest length, including the ventral fins. ‘The ends of the snout and tail are equidistant from the cloacal orifice. The snout is slender and prominent. The interorbital space is 32 in the length of the snout, measured from an eye or the middle of the mouth. The anterior borders of the pectoral fins, which are some- what sinuous, together form an angle of about 85°, The lateral angles are rounded. ‘he spiracle is large, its greatest diameter equals that of the eye. Numerous small spinules occur on the upper surface of the tip of the snout and close to the antero-lateral margin in its posterior half only. The superciliary ridge bears four spines in front and three behind. There are five mid-dorsal spines in the branchial region. Between the ocellus and the margin of the pectoral fin is a group of lanceolate denticles pointing inwards (probably characteristic of the male). The whole lower surface of the snout is covered with fine denticles. On the dorsum of the tail are three somewhat irregular rows of spines. The tail is naked below, the sides of the tail are spiny. Ann. & Mag. N. Hist. Ser.7. Vol. xviii. 22 dO Capt. R. E. Lloyd on some The mouth is widely but distinctly V-shaped ; in width it is 14 in the length of the snout. ‘here are eighty rows of teeth in the upper jaw and sixty in the lower. Teeth low and triangular, on a rhomboidal base. The edges of the nasal valves are deeply fimbriated and are united across the middle line by a distinct fold of skin, which is separated from the upper jaw by a deep curved groove. The dorsal fins are equal in length; the distance between them is greater than the length of either. Caudal fin small. Colour uniform brown above, with a dark ocellus at the base of each pectoral fin, surrounded by a paler ring. Uniform white below; the tail shows dark mottling on its lower surface. One small male specimen, measuring 36 cm. in its greatest length and 23 cm. in its greatest breadth, was taken from 130 fathoms in the Gulf of Aden. Raia reversa, sp. n. The greatest breadth of the disk is equal to the length from the snout to the root of the tail. The cloaca is slightly nearer the end of the snout than the end of the tail. The interorbital space is } the length of the snout measured from an eye or the middle of the mouth. The anterior borders of the pectoral fins are sinuous and together form an angle of about 80°. The snout is prominent. The lateral angle of the pectoral.fins is rounded. The spiracle is large ; its greatest diameter equals that of the eye. The skin over the skull, but not over the snout, is covered with fine denticles. The anterior half or more of the pectoral fins is covered with small denticles. ‘There are two series of larger spines on the pectoral fins, one series of about twenty opposite the shoulder-girdle (male characteristic probably) and another of about fifteen opposite the eye. There is one large white stellate spine in front of the eye and two or three smaller ones behind. There are four or five similar spines in the mid-dorsal line. On the dorsum of the tail are three regular rows of large spines, those of the middle row being about half as numerous as those of the lateral rows, new Deep-sea lish. 311 The sides of the tail are spiny. The lower surface of both disk and tail is smooth and devoid of spines. The two dorsal fins are equal in length and are in contact at their bases; the caudal fin is a minute fold. The mouth is transverse in its outer part and curved in the middle; its breadth is exactly half the length of the snout. There are forty-two rows of teeth across both upper and lower jaw. The teeth in the middle of the series are long and curved ; their bases are heart-shaped. Colours in the fresh state :—The upper surface of the disk is pure white, passing into dark grey at the margin of the pectoral fins. ‘The upper surface of the pelvic fins and claspers is grey. The iris is black, but the pupil has a white milky appearance: the anatomical cause of this was unfor- tunately not made out in the fresh state. The entire lower surface is purplish black. In consistency the whole body is soft and flabby ; when taken from the trawl it was rolled up in a cylindrical posture. The single specimen (a male), measuring 60 cm. in its greatest length and 33 cm. in its greatest breadth, was taken from §20 fathoms in the Arabian Sea off the Baluchistan coast. In the same trawl was obtained a black pillow-shaped egg with four hollow horns at the corners; this measures 24 by 14 inches. ‘lhe horns are not equal in length: those of one pair are 24 inches long and are separated by a straight border ; those of the other pair are 14 inch long and are separated by a tongue-shaped projection of the border, which constitutes a smaller fifth horn. The most characteristic features of this species are the soft flabby consistency in the fresh state and the remarkable coloration, which suggested the name R. reversa. In concluding these notes I must acknowledge my indebtedness to Lt.-Col. A. Alcock, I.M.S., F.R.S., who has kindly given me much help and advice in their production. Figures of these four species will be subsequently published in the “ ‘ Investigator’ Illustrations.” 312 Dr. A. 8. Woodward—The [elutions of XLITT.— The Relations of Paleontology to Biology * By A. Smira Woopwarp, LL.D., F.R.S. Tr is clear that the scientific value of a fossil depends upon the exactness with which the circumstances of its discovery are determined by a geologist. The briefest experience is also enough to demonstrate that the well-mineralized remains of an organism can only be satisfactorily interpreted by an observer who is familiar with the structure of rocks and their common constituents. The student of fossils needs as much elementary training in the geological succession of the rocks and the varied nature of mineralization as the student of histology and embryology requires to locate his sections with exactitude and to understand the action of the different stains and media he employs. In the one case nature makes the preparation, in the other case the processes of laboratory technique are responsible for the difficulties. In both cases there 1s scope for numerous fantastic conclusions if the properties of the preservative medium are misunderstood. Paleontology, however, is essentially a department of Biology, and it can only be prosecuted with success by a skilled biologist who has had the elementary geological and mine- ralogical experience just mentioned. It bears, indeed, the same relation to the whole world of life that embryology bears to the structure of an individual organism. ‘The one deals with the rise and growth of races and their varying relationships, the other describes and interprets the evolution of an indi- vidual and the processes by which the different parts of its mechanism are finally adjusted. Both, unfortunately, depend on extremely imperfect material ; for fossils are nearly always mere badly preserved skeletons, and they represent only an infinitesimal fraction of the life that has passed away, while enibryos are so much adapted to the peculiar circumstances of their environment that many of the essential stages in their growth and development are obscured and modified by temporary expedients. The past history of the world of life, as revealed by fossils, has long been familiar in its general outlines. At least a century has elapsed since it was made clear that the various organisms come into existence at different times and in a definite order, according to their grade in the scale of being, the lowest first, the highest latest. Several decades have * Extract from an Address delivered before the International Congress of Arts and Science, St. Louis, U.S.A., Sept. 22nd, 1904; published in the Congress Report, vol. iv., June 1906, Palawontology to Biology. 313 also passed away since it was recognized that within each group the lowest or most generalized members appeared earliest, the highest, most specialized, or most degenerate towards the end of the race. Modern research is concerned only with the details of this succession and with the laws which can now be deduced from the rapidly multiplying available facts. Our present knowledge of the geological succession of the fishes may be briefly summarized to show how Palzontology contributes to the solution of the fundamental problems of Biology. The earliest recognizable fish-like organisms, which occur in Upper Silurian formations, seem to have been mere grovellers in the mud of shallow seas, nearly all with incom- pletely formed jaws and no paired fins, devoting most of their growth-energy to the production of an effective armour by the fusion of dermal tubercles into plates (Ostracodermi). With them were a few true fishes which had completed jaws, but which possessed a pair of lateral fin-folds, variously sub- divided, instead of the ordinary two pairs of fins (Diplacanth Acanthodit). The main features of Silurian fish-life were, therefore, the acquisition of dermal armour, definite jaws, and the beginning of paired fins. Some of the lowly types thus equipped survived and further evolved in the Devonian period ; but the multitude of new-comers which then formed the majority were much higher in the scale of being (Crosso- plerygit). They were still adapted for the most part to live on the bottom of shallow water or in marshes, but they were typical well-formed fishes in respect to their jaws, branchial apparatus, and two pairs of fins. Nearly all their bones were external, very little of their internal skeleton being ossified, and the only changes they seem to have been undergoing related to the fusion of some of the head-bones and the more exact adaptation of their fins and tail to their environment. Tishes more fitted for sustained swimming were also be- ginning to appear, and these (Paleoniscide) formed the large majority in the succeeding Carboniferous and Permian periods. They were about equivalent in grade to the modern sturgeons, and the tendency towards change in their structure was in the direction of effective swimming, by the more intimate correlation between the fin-rays and their supports and by the shortening of the upper lobe of the tail. They still exhibited scarcely any ossification of the internal skeleton. As soon as the best type of balancing fin and the most effective type of propelling tail-fin had become universal among the highest fish-life of the Triassic period the internal skeleton began to ossify and vertebral centra arose. In fact, 314 Dr. A. 8. Woodward—The Relations of the whole of the succeeding Jurassic period was spent by the highest fishes in improving and finishing their internal skeleton, while their external bony armour began almost universally to degenerate. Thus, by the early part of the Cretaceous period the most advanced members of the class had already become true bony fishes or Téedeosteans. Having attained that stage of complexity, they admitted of mucli more variation than formerly, and then arose the immense host of fishes which characterize the Tertiary period and the present day. For the first time in fish-history there were fundamental changes in the head. First, in some genera the maxilla began to slip behind and above the premaxilla, so that it was excluded from the gape. Next, in these and most other fishes, the ear-capsules began to enlarge to such an extent that the original roof of the brain-case eventually formed only an insignificant part of the top of the skull. At the same time the lateral muscles of the trunk extended forward over the cranial roof, and various crests arose between them. Finally, it was quite common for the pelvic fins to be displaced forward beneath the pectoral fins, while the vertebree, as well as some of the fin-rays, were usually reduced to a definite and fixed number for each family or genus. Simul- taneously many of the fin-rays were modified into spines, and there was a constant tendency for the external bones and scales to become spinose. At all stages of this progress there were, of course, stragglers left by the way; and the modern fish-fauna is therefore a mixture of slightly modified survivors of many periods in the earth’s history. To state this brief sammary in more general terms, fossils prove that the earliest known fish-like organisms strengthened their external armour so long as they remained compara- tively sedentary ; that next the most progressive members of the class began to acquire better powers of locomotion, and concentrated all their growth-energy on the elaboration of fins; that, after the perfection of these organs, the internal bony skeleton was completed at the sacrifice of outer plates, because rapid movement necessitated a flexible body and rendered external armour less useful; that, finally, in the highest types the vertebre and some of the fin-rays were reduced to a fixed and practically invariable number for each family or genus, while there was a remarkable development oi spines. As survivors of most of these stages still exist, the changes in the soft parts which accompanied the succes- sive advances in the skeleton can be inferred. Hence Palwon- tology furnishes a sure basis for a natural classification in complete accord with the development of the group. Paleontology to Biology. 315 Now fishes are aquatic animals, and nearly all the fossili- ferous rocks were deposited in water. ‘The past history of this chain of life ought therefore to be almost completely revealed by the geological records. Making due allowance for the imperfection of collections and the accidental nature of the discovery of fossils, the general outlines of this history may indeed be considered as tolerably well ascertained. ‘Thus the facts of Paleontology not only aid the biologist in discovering the true relationships of the fishes ; at the same time they afford a definite means of determining with certainty some of the fundamental principles of organic evolution illustrated by them. As identical principles may be deduced from other departments of Paleontology, most of them are not likely to be altered in any essential respects by future discoveries. It must suffice here to allude only to a few of these general results which seem to be of far-reaching importance, omitting details which may be obtained from special treatises. Fore- most among them is the demonstration that the evolution of the animal world has not proceeded uniformly, but in a rhythmic manner. As soon as fishes had acquired the paddle-shaped paired fins, they suddenly became the special feature of the Devonian period in all parts of the globe that have hitherto been geologically examined, and they attained their maximum development, being more numerous and more diverse in form than at any subsequent time. None of these paddle-finned fishes (Crossopterygiz) in the course of their varied development made much approach towards passing into the next grade of fish-life with short-based paired fins and a heterocereal tail (Chondrostec); but among their earliest representatives there was at least one member of the higher group, which suggests that the latter arose when the previous group was just becoming vigorous. At the be- ginning of the Carboniferous period the higher grade of fish- life just mentioned suddenly became the dominant feature, and during the Carboniferous and Permian it attained its maximum development. ‘l'owards the close of the Permian period the next higher group was heralded by only one representative, but as soon as it arose in the ‘l'rias it resembled its predecessors in becoming immediately dominant, sur- passing all contemporary races of fishes both in the number of individuals and in the variety of genera and species. In the Cretaceous period the highest bony fishes appeared, and at the end of that period, with the dawn of the Tertiary, they suddenly diverged into nearly all the subdivisions which characterize the existing fish-fauna, accomplishing much more 316 Dr. A. 8S. Woodward—The Lelations of ev: lution in a brief interval than has taken place during the whole of the succeeding Tertiary time. In short, the funda- mental advances in the grade of fish-life have always been sudden and begun with excessive vigour at the end of a long period of apparent stagnation, while each advance has been marked by the fixed and definite acquisition of some new character—an “‘ expression point,” as Cope termed it—which seems to have rendered possible, or, at least, been an essential accompaniment of, a fresh outburst of developmental energy. As we have seen, the successive “ expression points ”’ among fishes were the acquisition of (1) paddle-like paired fins, (2) shortened fin-bases but persistent heterocercal tail, (3) completed balancing fins and homocercal tail, and (4) completed internal skeleton. When fossils are examined more closely, it is interesting to observe that the geological record is most incomplete exactly at these critical points in the history of each race. ‘There are abundant remains of the families and genera which are definitely referable to one or other order or suborder ; but with them there are scarcely any of the links between these major divisions which might have been expected to occur. It inust also be confessed that repeated discoveries have now left faint hope that exact and gradual links will ever be forthcoming between most of the families and genera. The “imperfection of the record,’ of course, may still render some of the negative evidence untrustworthy; but even approximate links would be much commoner in collections than they actually are if the doctrine of gradual evolution were correct. Paleeontology, indeed, is clearly in favour of the theory of discontinuous mutation, or advance by sudden changes, which has lately received so much support from the botanical experiments of H. de Vries. Further results obtained from the study of fossils have a bearing even on the deepest problems of Biology, namely, those connected with the nature of life itself. For instance, it is allowable to infer, from the statements already made, that the main factor in the evolution of organisms is some inherent impulse—the “ bathmic force” of Cope—which acts with unerring certainty whatever be the conditions of the moment. So far as human judgment can decide, the varied assemblage of fishes at each stage of the earth’s history was always in perfect accord with its environment and displayed very few signs of waning, even at the time when a new race suddenly took its place and provided every kind of fish once more on a higher plane or, so to speak, in a later fashion. The change was inevitable and according to some fundamental law of Paleontology to Biology. Ey life whose influence is independent of temporary equilibrium. Equally inevitable and irreversible are the essential changes which may be observed during the evolution of each family of organisms. As the late Professor Beecher pointed out *, all animals with skeletons tend to produce a superfluity of dead matter, which accumulates in the form of spines as soon as the race to which they belong has passed its prime and begins to be on the downgrade ; all vertebrates tend to lose their teeth when they reach the culmination of their life- history ; nearly all groups of fishes end their career with eel-shaped representatives; and when a structural character has been definitely lost in the course of evolution it never reappears, but, if actually wanted again, is reproduced in a secondary makeshift. Finally, and perhaps most important of all, there is in the course of evolution of all groups of animals to their prime a tendency towards fixity in the number and regularity (or symmetry) in arrangement of their multiple parts. The assumption of a fixed number of vertebrae and fin-rays in the latest and highest families and genera of bony fishes has already been mentioned. An irregular cluster of grinding-teeth characterized the Pycnodont fishes of the Lower Lias, while these teeth began to be disposed in definite regular rows in some of the Bathonian forms, and such a symmetrical arrangement henceforth pervaded the highest members of the family. Many of the lower vertebrates, both living and extinct, have teeth with multiplied cusps, and in some genera the number of teeth seems to be constant ; but in the history of the vertebrates the tooth-cusps never became fixed individual entities, strictly homologous in whole races, until the highest or mammalian grade had been attained. Moreover, it is only in the same latest phase that the teeth themselves can be treated as definite units, always the same in number (44), except where modified by degeneration or special adaptation. The number of vertebrae in the neck of the lower vertebrates depends on the extent of this part, whereas in the mammal it is almost invariably seven whatever the total length may be. Equally constant in the artiodactyl ungulate mammalia is the number of nineteen vertebrae between the neck and the sacrum. In short, the biologist equipped with an adequate know- ledge of Paleontology cannot fail to perceive that throughout the evolution of the organic world there has been a periodical succession of impulses, each introducing not only a higher grade of life, but also fixing some essential characters that * C. E. Beecher, “The Origin and Significance of Spines,” Amer. Journ. Science, [4] vol. vi. (1898), July to October. Ann. & Mag. N. Hist. Ser. 7. Vol. xviii. 23 318 Bibliographical Notices. had been variable in the grade immediately below. He must also realize that in the interval between these impulses some minor characters in the families similarly acquired fixity in their prime, until old age and extinction approached. The general conclusion is, that if the unknown influence which Cope has termed “ bathmie force ” were able to act without a succession of checks from the environment and Natural Selection, animals would form much more symmetrical groups than we actually find, and their ultimate grades would display still more instances of numerical fixity in multiple parts than can be observed under existing circumstances. This result almost tempts a paleontologist to risk the pitfalls of reasoning from analogy and to compare organic evolution with some purely physical processes. It has already been pointed out more than once that the initial stages of animal races resemble the nascent states of chemical elements in their particular intensity of vigour and unwonted suscepti- bility to influence ; while Cope himself has hinted that the ‘expression points ” in the evolution of races may, perhaps, be compared with the phenomena of Jatent heat in the inorganie world. It now seems reasonable to add that each “ phylum,” or separate chain of life, bears a striking resemblance to a crystal of some inorganic substance which has been disturbed by impurities during its growth, and has thus been fashioned with unequal faces, or even turned partly into a mere con- cretion. In the case of a crystal the inherent forces act solely upon molecules of the crystalline substance itself, collecting them and striving, even ina disturbing environment, to arrange them in a fixed geometrical shape. In the case of an organic phylum, the inherent forces of the colloid germ- plasm act upon a consecutive series of temporary outgrowths or excrescences of colloid substance (the successive individual bodies or “somata”), struggling not for geometrically arranged boundaries, but towards various other symmetries and a fixity in number of multiple parts. Palxontology thus contributes to Biology by placing the oft-repeated comparison of life with crystallization in an entirely new light. BIBLIOGRAPHICAL NOTICES.

Though Dr. Andrews had not, in many cases, the good fortune to unearth the first specimens of these remains to be discovered, it is to him that we owe their determination: to him that the credit belongs of interpreting the true nature of the puzzles they presented. But he has himself done much work in the burning deserts of Egypt, and many of the most important remains described here are due to the masterly intuition he displayed in the arduous work of fossil-hunting; many of the biggest prizes were obtained from ground that others on the same quest had already surveyed and pronounced barren! The greater part of this volume is concerned with that most important group, the Ungulates; and, undoubtedly, the most striking of these is the bizarre creature which has been named Arsinoitherium.
