I. On the Genus stamina, noi to the Family of the Capparidaceæ.
By JOHN Mires, Esq., F.R.S., F.L.S. Se.

Read January 18, 1848.

A TREE belonging to the Natural Order Capparidacee, growing in the arid desert
plain at the foot of the Cordillera de los Andes, which I examined with some attention in
1825, and which I then named Atamisquea emarginata (Travels, vol. ii. p. 529), was also
found about the same time by the late Dr. Gillies, from whose specimens Sir W. Hooker
subsequently first published its generic character (Botanical Miscellany, vol. iii. p. 143) ;
but as my Notes upon the living plant, illustrated by drawings made at that time, vary in
some respects from the excellent description given by that very distinguished botanist
from dried specimens, I have thought that my observations upon this little-known genus
may perhaps be acceptable to the Linnean Society.

The generie title is derived from the vernacular name, Atamisque. It is a tree of
withered and barren appearance, not exceeding 8 or 10 feet in height; the trunk is very
solid, and much bent; the wood, hard and of close grain, is of a yellow colour; the bark
is very thin and smooth, formed of several yellowish green, membranaceous lamin, peel-
ing off in flakes, and exposing the bare yellow wood. The branches are much bent and
tortuous; the younger shoots, which are furfuraceous and of a whitish hue, alone bear
leaves. The leaves are alternate, broadly linear, emarginate at both ends, 3 lines long and
1 line broad, of a somewhat coriaceous texture, veinless, very entire, polished, and of a
dark green above, with a central longitudinal groove over the midrib: in the young state
their upper face folds inwardly, with the margins adhering closely together; and when

they at length open, the leaf always remains somewhat canaliculate : below it is whitishly
furfuraceous, being covered with a tomentous down, that is almost wholly concealed by a
number of closely imbricate peltate scales with radiate ribs, which under a lens appear
like fish-scales: the petiole is short, white, and also lepidote. The flowers often axillary,
sometimes terminal, are altogether covered with imbricate scales ; the peduncles, one-fourth
to three-eighths of an inch in length, are usually solitary, but sometimes in pairs. The
. sepals are rounded, very deeply concave, the margins being very slightly imbricate before
expansion; they are at first reflexed, and soon break off transversely along the margin of
the torus; they are covered within by tomentous whitish hairs, and are lepidote outside.
The torus is a fleshy deep oval cup, which after the fall of the flower becomes hardened,
and. exhibits a somewhat bifid, erect tooth on its posterior or upper margin, and two other
smaller opposite teeth on its sides. The six petals arise in a single whorl from the inner
margin of the calycine cup, and are linear, and somewhat spathulate, being hairy within,
and covered on the outside with lepidote scales: four of these are of equal length, and
situated in pairs, opposite the sepals, while the two intermediate shorter petals are lateral,
and alternate with the two sepals; in æstivation, the margins of the summits are some-
what imbricately disposed, those of the shorter pair being exterior to the others; after ex-
pansion they are all thrown back, the upper pair remaining more erect. There are six
fertile and three sterile stamens, all seated.upon a small gibbous ring, just above the gla-
brous thickened base of the thecaphore; the sterile filaments are shorter than the others,
one of them being opposite to the upper petals, and the other two opposite to the lateral
petals, two fertile stamens interposing between them; the fertile filaments are as long as
the petals, and though somewhat plicated before expansion, are afterwards erect, and de-
flected outwards near the summit; they are quite glabrous, with a roundish fleshy gland
at the base, which is covered with whitish pubescence, and a few lepidote scales; these
glands being seated upon the gibbous ring before mentioned, make it almost appear as if
the stamens were monadelphous, but they are in reality free to the base. The anthers,
which are oblong and basifixed on the apex of the filaments, are coriaceous, 2-celled, burst
inwardly by longitudinal furrows somewhat in front, and afterwards curl downwards in an
annular form. The thecaphore arises somewhat laterally from the bottom of the hollow
cup-shaped gibbous torus, and is inclined upon its shorter side; the lower part, which is
glabrous, rises to the height of the cup, forming the staminiferous support above men-
. tioned, one side of this support adhering to the lower and shorter portion of the cup, the
opposite side being free and channeled almost to its axis; above this level the thecaphore
becomes more slender, is again inclined further downwards, and rising to the height of
the stamens bears upon its summit the ovarium, which, with the slender portion of the
thecaphore, is densely lepidote. The ovarium is of an oval form, somewhat nodding; the
style is very short, and the stigma is almost obsoletely 2-lipped. The fruit is a somewhat
fleshy berry, covered with lepidote scales, about 3 lines long and 2 lines in diameter; it is
unilocular, bearing generally two seeds, which almost fill the cavity; the epicarp is thin’
and somewhat coriaceous, and separable by pressure into four equal segments, leaving the
seeds, and the small quantity of enveloping pulp, contained within four slender cartilagi-
nous ribs, which arise from the base of the cell and unite in the apex; these ribs corre-

spond with the edges of the segments, which show by their laceration that their adhesion
with each other and with the ribs has been complete. Within and opposite to the lower-
most of these ribs arises a funiculus or placenta, which on reaching about two-thirds the
height of the fruit, branches off right and left, by two short threads, towards the hilum
of the two seeds, where they are respectively attached. The seeds are smooth, of a dark
red colour, reniform, or of a cochleate shape, somewhat flattened on their adjacent sides, 1
and roundish without. The testa is coriaceous, having on one side an incomplete cell,
formed by the convolution of the inner margin about the umbilical sinus; the outer in-
tegument is brownish, opake, and striated, and adhering to the testa forms between the
flexure of the embryo an extension of the false dissepiment of the spurious cell, which
serves to inclose the radicle: the inner integument is membranaceous, and marked about
the middle of the cotyledons with a broadish thickened chalaza. The embryo is oblong,
and bent sharply inwards at both extremities, the ends of the cotyledons and of the radicle
being mutually turned towards each other, so that it may be said to be truly campylo-
tropous: the cotyledons are convolutely plicated, and somewhat white and foliaceous. i

From the facts above stated it may be inferred, that the arrangement of the floral enve- -
lopes in this genus is contrary to the usual structure of the Capparidacee, which offer
generally four sepals, four alternate petals, usually eight or more stamens, and a fruit,
usually of two cells, with two or more placentæ. Sir W. Hooker, in his generic character _
of Atamisquea (loc. cit. p.148), regards its floral teguments as consisting of four sepals
and four petals, in conformity with the ordinary arrangement in this family: it will be

against the opinion of so high an authority. It appears to me however warranted by the
they are continuous at
their origin with the margin of the cup of the torus, while the insertion of the six narrower
segments (petals) is upon one line, within the margin of the same cup, which is proved —
by the fact, that when the sepals and petals fall away, the rupture of the former is marked _

an entire envelope that bursts into two valves, viz. in Busbeckia, Endl., Steriphoma, Spr.,
and Morisonia, Plum. The apparent inconsistency of this distribution will BR: if

of four segments into two, while the inner series of six segments may be viewed as nor-
mally consisting of four leaflets, that is to say, with two of the opposite petals somewhat
depauperated, while the intervening ones are cleft nearly to their base. This latter view
is rendered somewhat the more probable, by the apparent insertion of all the six petals
upon one line, and by the cohesion of the upper and lower pairs by their claws, when torn
away from their place by force: the appearance of the teeth, or indurated remains of the
claws of the petals, that are distinctly seen on the inner margin of the persistent calycine
cup, corroborates this view of the case, which is further confirmed by the fact, that when
dried each of the sepals by pressure easily splits down ‘the middle, by a clean line, into
two distinct segments.

II. On the Development of the Qbule in Orchis Morio, Linn.
By ARTHUR HENFREY, Esq., FLS. gir:

Read April 3, 1849.

IN the spring and summer of last year I made many observations on the young ovules
of various plants, with the view of testing the various doctrines on this subject, which
had acquired new interest from the recent researches of Amici, Mohl and others. Only
one series of my investigations attained anything like completeness; but in Orchis Morio
I believe that I have seen and can confirm all that the above-mentioned observers have
described; and I now present my results to the Linnean Society, partly because I believe
that in the present state of the question all evidence derived from careful observation is of
some value, and partly because I*have succeeded in obtaining a more complete series of
figures illustrating the successive conditions of the ovule than has yet been published; .
Mohl, who gives the most complete àecount of the development in Orchis Morio, having
given no drawings. The following account is drawn up from my notes made during the
observations, principally in the month of May 1848.
. May 3rd. In the ovaries of flowers which had just opened, and were without signs of

pollen upon the stigmatic surface, the ovules, about 545th of an inch long, were just
curving over toward the anatropous position; in some the axis of the nucleus formed
nearly a right angle with the funiculus (Tas. II. figs. 4 & 5). The nucleus projected
beyond the cells, forming the single coat of the ovule, and consisted of a large central cell
(the embryo-sac), enclosed by a layer of very delicate cells of small size, constituting a
proper coat of the nucleus. |

May 9th. The ovules of fully expanded flowers were not much altered, except in the
much clearer definition of the walls of the cells. The embryo-sac was filled with a clear,
colourless fluid, in which floated minute black atoms, scarcely large enough to deserve
the name of granules. In some flowers the stigmas were smeared with pollen, but often
from the anthers of other flowers, their own being still closed. These pollen masses sent
down numerous tubes, which differed much from any of the cells of the tissue in which
they were engaged. The pollen-tubes were always about th of an inch in diameter,
at most one-fourth of the size of the smallest of the surrounding cells, which were also
short and often irregular in form, while the pollen-tubes always appeared as long, slender
filaments. / |

May 13th. The flowers withered and the stigmas covered with pollen. A dense bundle
of tubes lay in the midst of the lax tissue of the canal leading to the cavity of the ovary.
The ovules were considerably advanced, some being quite anatropous (fig. 6), others three-
fourths reversed; those quite anatropous were about 735th of an inch in length. The two
coats of the ovule (tegmen and testa) were now distinctly evident; the length of the testa -

8 MR. HENFREY ON THE DEVELOPMENT

varied; sometimes it half enveloped the tegmen, in some ovules it had grown up further -
over it. The inner coat, the tegmen, had not grown over the nucleus in all the ovules,
but in most it projected beyond. The nucleus was still covered by its own cellular coat
and still contained only the clear, colourless fluid with black points.

May 16th. The ovaries more advanced ; the pistillary cords extended nearly to the base
of the ovary, lying in the grooves formed between the projecting placentas and the walls 1
of the ovary, apparently free, and composed of delicate tubes presenting all the chara
of pollen-tubes, and apparently continuous with these, as derived from the pollen on the
stigma. The ovules (fig. 8) exhibited considerable alteration. Most of them were e
larged, and the outer coat had developed much in the chalazal region ; its cells were large
and more clearly defined. The inner coat, which appeared to be tolerably independent of
the outer at the sides, as air passed freely between them, had grown up far beyond the}
nucleus, and its cell-walls had acquired more consistence. The nucleus was much |
changed; the embryo-sac had lost its proper cellular coat, which had disappeared either
by solution or by pressure, probably the former, as a free space existed sometimes beg
tween the inner coat and the nucleus; and in some cases the solution appeared imperfect, |
extending only to the cross walls of the cells, so that the embryo-sac was contained in an
outer sac consisting merely of the outer walls of the cells of its coat.. The embry0-sa¢ |
now had the aspect of a large ovoid sac attached by a cellular pedicle to the chalazal
region, and contained opalescent mucilaginous matter (protoplasm), in most cases accu-
mulated at the ends, chiefly at that next to the micropyle. There was no sign of a nu-
cleus or nascent cell yet. 1

May 20th. The embryo-sacs exhibited the collections of. protoplasm at the two ends. At
the micropyle end new phenomena presented themselves: either one; two, or (and i
usually *) three minute vesicles (figs. 11-14) had been formed from the protoplasm, and
always seemed to me to originate as cavities excavated in the mucilage, not as if formed by |

the formation of membrane on the outer surface of a nucleus (cytoblast) or globule of ]

mucilage. These vesicles soon appeared as distinct cells, with exceedingly delicate walls,

lying at the micropyle end of the embryo-sac, and undoubtedly existed there before the
pollen-tubes entered the foramina of the ovules, | !

In some of the ovules examined this day the pollen-tubes had entered the ovules, and I
traced them d

; own through the wide mouth of the outer coat and the narrow canal of the
inner, as far as the apex of the emb

; ryo-sac. They never entered this, but generally
appeared to be diverted a little to one side

: ‚and to lie in contact with its outer surface t,
Just over the place where the minute vesicles lie within. |

May 31st. I examined a number of ovules in various stages, repeating the observations |
on the earlier conditions with similar results. I traced the pollen-tube down to the em-
bryo-sac in several specimens (fig. 15): in one case it appeared flattened against the mem-
| brane of the embryo-sac (fig. 17) ; in other cases (figs. 15, 16, 19, 20) I traced it a little way

down the side of the summit of the embryo-sacs, which always contained the vesicles
within. In some embryo-sacs (figs. 20-26) one of the vesicles had begun to develope
further, dividing into two cells by a horizontal septum, the upper dividing again and grow-
ing out in a conical form through the endostome, to produce the confervoid filament which
was described by Mr. Brown, and which Schleiden has certainly mistaken for a develop-
ment of the pollen-tube.

June 3rd. Traced the pollen-tubes to the embryo-sac, and saw them lying on the out-
side, and again satisfied myself that the vesicle within the embryo-sac (the germinal ve-
sicle) is the first cell of the embryonic body. It generally exhibits a slight collection of
protoplasm at its base, and soon after the pollen-tube reaches the surface of the embryo-
sac divides into two cells, the upper dividing again and growing out into an articulated
filament, the cells of which are formed by the production of septa in the same way as in
Confervas, hairs of Phanerogamia, &c., the mucilaginous layer (or primordial utricle of
Mohl) being rendered very evident by the application of iodine (fig. 29). The lower part
of the embryonic body enlarges while the filament is growing out, and soon perfectly fills
the embryo-sac. It appears to me that the process of cell-formation in this lower part,
by which the embryo is produced, varies in different cases; generally the lowest cell
enlarges very much and becomes filled with dark mucilaginous matter, and then this is
soon divided into a number of cells by the formation of septa. Nuclei were visible in all
the cells very soon after their origin, but I could not form an opinion as to their relation
to the cell-formation, or determine how or at what period they were really produced. In
the earliest condition they resembled clear vesicles, not granular bodies such as Schleiden
describes.

In some cases two confervoid filaments are produced, two of the germinal vesicles
undergoing development. I met with this several times, but omitted to draw them, in
the hope of subsequently finding a more favourable specimen, which I was not fortunate
enough to do.

The obvious conclusions from the foregoing observations appear to be, that the embryo
is really produced by the ovule itself; that a germinal vesicle exists within the embryo-
sac before the pollen exerts its influence; that the pollen-tube penetrates the coats of the
ovule to reach the embryo-sac; and that the passage of the pollinic fluid through the
intervening membranes impregnates the germinal vesicle and determines its development
into an embryo. :

Since the investigations were made with every precaution, and their results are in per-
fect accordance with those of Amici, Mohl, Müller and others, I think that I am justified
in believing them to be a sufficient refutation of Schleiden's views, so far as the plant in
question is concerned; but as to their positive value, as to the evidence they afford of the
actual nature of the process of impregnation, I still regard them as insufficient. I am
not convinced that the whole of the pistillary cords are composed of filaments directly
produced by the pollen-granules. It is not yet shown whether there is any relation
between the application of the pollen on the stigma and the development of the germinal
vesicles; it is only clear that these last exist before the pollen-tubes enter the ovules.

Lastly, although the production of the confervoid filaments appears to be a normal pro-
cess, it is still a question open to doubt when only observed in ovaries containing such an
abundance of ovules as Orchis Morio. T

The facts I have detailed above are, however, agreeable with what I have observed in
certain other plants, in some as yet imperfect investigations ; I hope to be able to complete
them, and to repeat the earlier examinations with especial reference to the doubtful points,
in the course of the ensuing summer.

Ill. On the Australian Species of the Coleopterous Genus Bolboceras, Kirby.
By J. O. Wesrwoon, Esq., F.L.N.

Read March 21st, 1848.

Bor OCERAS, a genus of Lamellicorn beetles, was proposed by the Rev. W. Kirby,
in his excellent memoir published thirty years ago, in the 12th volume of the ‘ Transac-
tions of the Linnean Society,’ containing descriptions of New Australian Coleoptera col-
lected by Mr. Robert Brown. In his observations appended to the Latin characters given
of the genus, as contrasted with those of Geotrupes, Mr. Kirby more especially endeavoured
to point out the differences between these two genera, alluding, among other things, to the
structure of the outer lobe of the maxillæ, but not mentioning (except in the Latin cha-
racter) the horny inner lobe, with its bipartite structure, a character (as Mr. MacLeay has
shown) of the highest importance, as distinetly indicating a variety in the operation of
manducation, and consequently in the nature of the food of the inseets. It is evident that
Mr. Kirby’s description of the maxilla of Bolboceras was drawn from the inaccurate figure
of that part given in pl. 23. fig. 5d, which omits the upper portion of the lower lobe of the
maxilla, which is thereby reduced to a single horny point. The maxilla of Bolboceras is,
however, almost exactly similar to that of Athyreus; indicating, in conjunction with the
general appearance of the insects, an analogous mode of life, although the difference in the
place of insertion of the middle feet must evidently be regarded as a proof of some distine-
. tion in the habits of the two genera.

Mr. Kirby's observations, it will be further seen, are directed to the structure of the
antennæ and trophi alone. There are consequently two important characters derived from
the external structure of the other parts of the insects which separate the two genera,
rendering Bolboceras also as far removed from the type of the family Geotrupide as Athy-
reus. These are, the entire structure of the eyes in Bolboceras, whilst each eye is divided
into two parts by a distinct septum in Geotrupes, and the want of a patch of orange
plush-like hairs on the thighs of the fore-legs, which exists in Geotrupes.

Mr. Kirby mentions as belonging to Bolboceras, “ Sc. mobilicornis, Linn. (of which Sc.
testaceus; Fabr., is only a variety), quadridens, Linn., farctus, Fabr., Lazarus, Fabr., Cy-
clops, Oliv., &e.,” together with the new species which he described under the name of
Bolboceras australasie, a name now proved to be inapplicable, not only because we pos-
sess many Australian species of the genus, but also because the insect so described is but
the female of another species. Of the above-mentioned species, the first, Sc. mobilicornis,
does not belong to the genus Bolboceras, from which it is distinguished by its bipartite
eyes, although the structure of the maxille and the want of a patch of plush on the fore
femora show its near approach to it. It will therefore be proper to apply the generic

name of Odonteus, given to this genus by Koppe, instead of Bolboceras, as it stands at
; c 2

present in English collections and books. The species, moreover, which it will be ad-
visable to regard as the type of Bolboceras, will be Se. quadridens, Linn., as that was the
species dissected by Mr. Kirby.

In 1819 Mr. MacLeay published the description of his genus Elephastomus in the first
part of his ‘ Hore Entomologice,’ founded upon the singular Australian Scarabeus pro-
boscideus, first described by Schreibers in the 6th volume of the * Linnean Transactions.’
In this strange insect the crown of the head is extended forwards, so as to push the ordi-
nary front part of the head, including the clypeus, mandibles and labrum, quite under-
neath it; just as if the human forehead were dilated over the entire face, and the nose and
mouth pushed between the chin and the throat; with this difference, that in the insect
the horizontal upper lip and mandibles become perpendicular, whilst the opposite would |
be the case in a human head so deformed. Referring again to the structure of the maxillee,
we find Mr. MacLeay’s description of those of Elephastomus, ** Maxillæ cornes, arcuate,
intüs dente acuto et ad apicem lacinià obtusà ciliis spinosulis armate," incorrect, omitting
_ to notice the upper portion of the inner lobe of the maxille ; whilst the figure given of it,
pl. 2. fig. 10 5, is still more incorrect, omitting both the horny teeth of the lower lobe. In
this, however, and all its essential characters, this insect approaches so closely to Bolbo-
ceras Australasie, that, long ago, I had attached to a figure of ZI. proboscideus the follow-
ing note: “ Is not Bolboceras australasie of Kirby the female? The box-like clava of their
antennæ agrees ;” and in Dr. Klug’s excellent Monograph on the genera Athyreus and
Bolboceras, published in the * Transactions of the Berlin Academy’ for 1843, we find Sca-
rabeus proboscideus given as the first species of Bolboceras, with Bob. Australasie as its

lary palpi and the identical structure of the two mandibles, which are bifid at the tips.
The number of the species of the genus Bolboceras was considerably increased by the
late Mr. Bainbridge, who published a short paper on some of the’ Australian Species, from

the Collection of the Rev. F. W. Hope, in the ‘Transactions of the Entomological Society’;
in their several works; and especially by Dr. —

which is now also incorporated that of M. Gory.
The circumstance of

the Athyrei, must be regarded as very aberrant species in the family of which our Geo-
trupes is the well-known type.

It has been thought advisable that a continuation of this paper, containing descriptions
of many additional new species of Bolboceras from India and other foreign regions, should
be published as a distinct memoir, which accordingly appears as the following article.

as a species from the former t.

IV. Descriptions of some new or imperfectly known Species of Bolboceras, Kirby.
By J. O. Wesrwoon, Esq., F.L.S.

Read June 6, 1848.

HAVING in two previous communications described a number of new species of Athy-
reus, chiefly from South America, and given a synopsis of the Australian species of Bolbo-
ceras, I shall on the present occasion continue the descriptions of the species of the latter
genus, especially such as are natives of the East Indies.

With the view of showing the generic as well as sexual distinctions existing between
the Bolbocerata and Odontei, I have given figures of the head and front of the prothorax
of both sexes of Odonteus mobilicornis and Bolboceras Æneas, Pz. (quadridens, Dftschm.)
from Austria, together with the side of the head (showing the eyes), maxillæ and fore
femora of both these insects. (Tas. IV. fig. 1 & 2, with the details.)

Obs. M. Gory’s specimen, from which Count De Laporte drew his description, is now in
Mr. Hope’s Collection before me, bearing a label, “ Bolboceras ferrugineus, Fabr., Ind. or.”
Fabricius, however, described no Scarabeus under such a name, whilst the Scarabeus Jer-
rugineus of Olivier (Ins. 1. Gen. 3. p. 148. pl. 28. fig. 202) does not belong even to the
present genus, and is from Senegal. It is possible that it may prove to be the other sex
of B. furcicollis, De Lap.

V. Experiments and Observations on the Poison of Animals of the Order Araneidea,
By Joux BLACKWALL, Esq., PLS. $c.

Read December 19, 1848.

MUCH has been written about the deleterious property of the transparent colourless
fluid emitted from the minute orifice situated near the extremity of the fangs of spiders
on the side next to the mouth, when those instruments are employed to inflict a wound.
The numerous accounts which have been published by various authors of the singular
effects induced in the human species by the bite of the Tarantula (Lycosa tarantula apu-
Ue, Walck.), and of the still more extraordinary mode of cure, together with the serious
and sometimes fatal consequences which have been attributed to the bite of the Malmig-
natte (Latrodectus malmignatus, Walck.), must ‘be regarded as amusing fictions in the
natural history of the Araneidea; and if the opinion, prevalent among arachnologists of
the present day, that insects pierced by the fangs of spiders die almost instantaneously,
should be found on examination to be at variance with well-ascertained facts, it must in
like manner be deemed fanciful.

For the purpose of testing the validity of this opinion, which I had reason to doubt,
and in order to determine with a nearer approximation to accuracy than had previously
been done, some of the effects produced under divers circumstances by the poison of spiders,
more especially the degree of influence it exercises in destroying the vital functions of ani-
mals, in the summer of 1846 I commenced an experimental investigation of the subject,
the particulars of which are comprised in the following pages.

To avoid confusion, the experiments have been arranged under four distinct heads,
corresponding to the objects upon which they were made; namely, the human species,
spiders, insects, and inanimate substances. It may be proper to premise that all the
animals were adult individuals in vigorous health, and that the temperature of the atmo-
sphere, in every instance recorded, was ascertained by means of a thermometer graduated
according to Fahrenheit’s scale, and exposed to the open air in a shady situation having a

northern aspect.
1. Experiments on the Human Species.

On the 19th of July 1846, a female Epeira diadema was induced to bite me on the inner
side of the left hand, near the base of the forefinger ; it continued to force its fangs deeper
. into the flesh during a period of many seconds, and at last quitted its hold voluntarily,
when a little blood issued from the wounds it had inflicted. Though the spider was in a
state of great excitement from previous irritation, yet I did not experience more inconve-
nience from its bite than from a puncture made near it at the same time with a fine
needle; indeed, allowing for a considerable degree of compression in the former case, the
effects of both injuries appeared to be very similar. The thermometer, while the experi-

32 MR. J. BLACKWALL ON THE POISON OF

ment was in progress, stood at 76°; the air throughout the day was sultry, and an exten-

sive thunder-storm occurred in the evening.

A highly exasperated female Epeira diadema was allowed to seize me on the inner side
of the left fore-arm, near the carpus, on the 30th of J uly 1846. It continued for more
than a minute to bury its fangs deeper in the flesh, and on quitting its hold voluntarily a
little blood flowed from the wounded part, near which a puncture was made simultaneously
with a fine needle. The air was sultry, the temperature at the time being 75°, and distant
thunder was heard. No difference was perceptible between the results of this and the
preceding experiment.

rially from those of a wound made near it at the same time with a needle of an average
size, the intensity and duration of the pain being very similar in both instances.

On several occasions, in the month of August 1846, spiders of various species were in-
duced, under the influence of excited feelings, to seize a piece of clean window-glass with
their fangs, when the transparent fluid which escaped from the small aperture near their

powerfully acrid pungent taste being the immediate consequence. A contrast equally

secreted by the insects caused inflammation accompanied by acute pain; effects, which if
produced at all by that secreted by the spiders, were scarcely appreciable.

feed freely on the flies introduced toit. The thermometer, at the time the experiment was
made, indicated a temperature of 74°.

In a hostile encounter between two female spiders of the species Segestria senoculata,
on the 29th of July 1846, one of them was pierced by the fangs of her opponent on the
under side of the abdomen, near the spinners. A transparent colourless fluid oozed from
the wounds for many minutes, and ultimately coagulated; but the spider seemed to expe-
rience little inconvenience from the injury, being lively in its motions and preying eagerly
upon the insects with which it was supplied. The temperature at the time was 76°, and
the atmosphere was highly electrical.

A female Ciniflo atrox was bitten by an exasperated female Lycosa agretyca near the
middle of the cephalo-thorax, on the 29th of July 1846, the temperature by the thermo-
meter being 76°. The Lycosa retained its hold for many seconds, and on quitting it volun-

"tarily a transparent colourless fluid flowed from the punctures and coagulated. The
wounded spider, apparently regardless of the injury it had received, spun a web with
which it long continued to ensnare its victims.

On the same day, the mercury in the thermometer denoting a temperature of 75°, a
female Epeira diadema, in a violent struggle with a female Celotes saxatilis, pierced her
abdomen in the medial line of the dorsal region, about a third of its length from the
spinners. The wounded spider did not exhibit any marked symptoms of distress and
speedily resumed its accustomed habits.

In an attack made by a female Ciniflo ferox upon a female Lycosa agretyca, on the
30th of July 1846, the temperature being 74°, the latter was wounded by the fangs of its
assailant at the base of the coxa of the left posterior leg, and a transparent fluid, which
soon coagulated, issued from the injured part. Nothing occurred afterwards to indicate
that the Zycosa had suffered from the encounter. |

Two female spiders of the species Æpéira diadema engaged in a severe contest on the
30th of July 1846, the thermometer standing at 73°, when one of them was seized by the
fangs of her antagonist near the middle of the right side of the abdomen. A brown fluid
flowed from the punctures and soon coagulated, but the spider appeared to be only slightly
and very briefly affected by the injury. sx

A female Epéira diadema, in a highly excited state, bit itself near the middle of the
femur of the left anterior leg, on the 5th of September 1846. The temperature at the
time was 69°, and a transparent fluid flowed copiously from the wounded part; coagula-
tion, however, quickly ensued, after which the spider manifested no unfavourable symptom
whatever. . : :

Extensive mechanical injuries commonly prove fatal to spiders, whether received in
conflicts with their congeners or otherwise, the extinction of life being Por less rapid
in proportion to the vitality of the part lacerated; but no Aus ign Bid the ge
going experiments indicates that the fluid emitted from the o ifice Br "i Bis o 4 e
Araneidea possesses a property destructive to the existence of animals of that order when
transmitted into a recent wound ; in short, it does not appear to exercise any greater de-

gree of influence upon them than it does upon the human species.

I now proceed to show how insects are affected when pierced by the fangs of spiders.

3. Experiments on Insects.

1846. August 7th. A female Zpéira diadema inflicted a severe wound on the mesono-
tum of a common Wasp, near the base of the right anterior wing, at 11" a.m., the tem-
perature at the time being 74°. The wasp, though disabled from flying, survived the
injury for the space of thirteen hours.

August 7th. At 1° 30" p.m., the temperature being 72°, a female Epéira diadema
pierced a Humble-bee, Bombus terrestris, with its fangs near the posterior part of the
mesosternum. ‘The wound deprived the humble-bee of the power of flight, but did not
terminate fatally till 11° p.m. on the 10th. _

August 8th. Temperature 68°. A female Segestria senoculata seized a Flesh-fly, Musca
vomitoria, near the middle of the tibia of the right posterior leg, and did not quit its hold
for several seconds. A transparent colourless fluid issued from the wounds made by the
fangs of the spider, but the fly retained the use of its wings, and did not expire till even-
ing on the 10th. |

August 13th. Temperature 64°. At 5^ 15" p.m. a female Segestria senoculata inserted
its fangs about the middle of the abdomen of a large Green Grasshopper, Acrida viridis-
sima, and retained its hold, which it quitted voluntarily, for many seconds. A greenish-
yellow fluid flowed copiously from the punctures, yet the insect continued to be lively in
its movements, leaping with agility up and down the glass vessel in which it was confined,
and ceased not to exist till midnight on the 15th.

August 14th. Temperature 66°. A female Epeira diadema pierced a large Green Grass-
hopper at 4^ 43" P.M., burying one fang at the base of the antenna on the right side, and
the other in the right eye. The spider retained its hold for several seconds, and on quit-
ting it a greenish-yellow fluid issued from the former wound and a dark brown fluid from
thelatter. Notwithstanding the serious injuries the grasshopper had received, no dimi-
nution of its activity was apparent, and it did not expire till afternoon on the 16th.

August 29th. Temperature 69°. At]1^ 22" P.M. a Hive-bee had its abdomen extensively
lacerated near the middle of the left side by a female Epéira quadrata. A large quantity
of transparent fluid flowed from the wound, but death did not ensue till 3^ 18" p.m.

September 3rd. Temperature 68°. A common Crane-fly, Tipula oleracea, punctured
by the fangs of a female Segestria senoculata, at 4^ 35” P.m., about a quarter of an inch
from the posterior extremity of its abdomen, survived till 8^ T" P.M. |

September Tth. Temperature 69°. At Ir 45» P.M. a Flesh-fly was bitten by a female

September 10th. Temperature 65°. At 1" 13” p.m. a common Crane-fly was pierced
through the left side of the abdomen, near the middle, with a fine needle; the insect ex-
pired on the same day, at 5^ 29" p.m.

September 10th. Temperature 65°. The point of a strong needle was deeply inserted
into the right side of the abdomen of a large Green Grasshopper, near its anterior extre-
mity, at 1'20" p.m. "Though the injury was severe, the life of the insect did not become
extinct till 7° 41" p.m. on the 12th.

September 10th. Temperature 66°. The right side of the abdomen of a common Wasp
was penetrated near the middle with the point of a fine needle, at 2^ 5" p.M.; a transpa-
rent fluid oozed from the puncture, and the life of the wasp terminated at 10^ 20" p.m.

September 18th. Temperature 60°. A male Tegenaria civilis deeply inserted its fangs
near the middle of the mesonotum of a House-fly, Musca domestica, at 10" 10" a.m., and
retained its hold for more than an hour and a half. The victim continued to manifest
unequivocal signs of life till 10" 44” A.w., and appeared to sink gradually from mere ex-
haustion. All the time it was in the grasp of its enemy, with the exception of short
intervals, it was perceived to have a slight nodding motion, which was discovered to be
caused by the act of deglutition on the part of the spider, a synchronous motion being
always observed in the fluid suddenly and copiously propelled into the spider's mouth,
and then by degrees reduced in volume in exact proportion to the continuance of the
nutation. Whenever the fluid was withdrawn from the mouth a fresh supply was speedily
introduced, and after mingling with that extracted from the body of the fly, was conveyed
into the stomach of the spider by a repetition of the act of swallowing, thus occasioning
the nodding motion with intervals of repose apparent in its prey.

September 18th. Temperature 61°. At 10° 20" a.m. a female Tegenaria civilis seized a
House-fly with its fangs near the middle of the mesonotum, and did not relax its hold for
more than an hour. The struggles of the fly became gradually more feeble, till they
ceased altogether at 10^ 47" a.m. The nodding motion of the victim, and all the attendant
cireumstances, were as conspicuous in this instance as in the preceding one.

September 18th. Temperature 64°. A female Segestria senoculata penetrated with its
fangs the right side of the mesonotum of a House-fly at 1° P.M., but did not deprive it of
life till 1° 29" p.m. The spider kept its hold about an hour; and a nodding motion of the
fly, regularly accompanied by the act of deglutition in its destroyer, with brief and simul-
taneous pauses in both, was observed during the entire period.

1847. July 15th. Temperature 71°. At 5" 3" p.m. a brilliant Green Fly, Musca cæsar,
was pierced by the fangs of a female Agelena labyrinthica near the posterior extremity of
the abdomen, on the under side. After retaining its hold about ten minutes the spider
transferred it to the middle of the mesosternum, perforating the part and rapidly extract-
ing the fluids of its prey, whose existence terminated at 5" 26" PM. A nutation of the fly
was constantly observed to accompany the action of swallowing in its adversary.

July 19th. Temperature 70°. A female Agelena labyrinthica struck its fangs into the
left side of the mesonotum of a Flesh-fly, at 12^ 23” r.m., and eagerly extracted its fluids,
the act of deglutition being attended with the usual nodding motion of the victim. After

ineffectual efforts to escape the insect became exhausted, and finally expired at 12^ 43^ p.m.

These experiments do not present any facts which appear to sanction the opinion that
insects are deprived of life with much greater celerity when pierced by the fangs of spiders
than when lacerated mechanically to an equal extent by other means, regard being had in
both cases to the vitality of the part injured, as the speed with which existence terminates
mainly depends upon that circumstance. It is true that the catastrophe is greatly acce-
lerated if spiders maintain a protracted hold of their victims, but this result is obviously
attributable to the extraction of their fluids, which are transferred by oft-repeated acts of
deglutition into the stomachs of their adversaries.

From the entire mass of evidence supplied by the experiments taken in the aggregate,
it may be fairly inferred that whatever properties characterize the fluid emitted from the
orifice in the fangs of the Araneidea, it does not possess that degree of virulence which is
commonly ascribed to it, neither is it so destructive to animal life when transmitted into
a recent wound as it is generally supposed to be. Were I disposed to speculate upon the
manner in which it affects insects on being introduced by the fangs into their vascular
system, I might conjecture that it has a tendency to paralyse their organs of voluntary
motion, and to induce a determination of their fluids to the part injured; but I refrain
from dwelling upon a suggestion, however plausible it may appear to be, which in the
present state of our knowledge of the subject can only be regarded as hypothetical.

4. Experiments on Inanimate Substances.

In the month of September 1846, litmus paper presented to spiders belonging to several
genera when in a state of extreme irritation, having their fangs extended, and the trans-
parent fluid which issues from the fissure near their extremity conspicuously accumulated
there, on being seized invariably became red as far as the fluid spread round the punctures
made in it, a result clearly proving that this animal secretion, though tasteless, is an acid.
Care, however, must be taken, in conducting the experiment, not to suffer any fluid from
the mouth to blend with that which proceeds from the fangs, either before or after it has
been transferred to the litmus paper, the former, rendering the blue colour of the test
more intense, and restoring it after it has been converted to red by the action of acetous
acid, being decidedly an alkali; consequently, if both combined in due proportions, they
would neutralize each other; but as there is usually a much more copious supply of the
alkaline than of the acid fluid, its agency would predominate, and scarcely a trace of red
would be discerned on the litmus paper.

Submitted to the same chemical tests, the fluid contained in the stomachs of spiders
and that Which flows from wounds inflicted on their bodies and limbs were found to be
alkaline. Now if the frequency and suddenness with which large quantities of fluid are
propelled into the mouths of spiders when occupied in extracting nutriment from their
prey be borne in mind, the conclusion that they must be ejected from the stomach through
the narrow @sophagus and pharynx seems to be inevitable *, as there is not any other

source known whence they could be derived; and it has been ascertained that if they are
applied to litmus paper, which has or has not been reddened by acetous acid, they always
produce upon it effects precisely similar to those caused by the gastric fluid, or rather by
the fluid contents of the stomach, when subjected to such tests. I may remark that the
yellow colour of turmeric paper is rendered brown by the application of the fluids from
the mouth and stomach, and that it is restored again by the agency of the fluid secreted
by the poison-glands, changes which afford another proof, in addition to those already
advanced, of the respective alkaline and acid properties of these animal products.

The instruments employed by the Araneidea to seize and destroy their prey are im-
properly denominated mandibles; I say improperly, because they actually do not consti-
tute any part of the oral apparatus, as Mr. W. 8. MacLeay has plainly asserted * ; indeed,
many eminent zootomists, judging from their position and from the origin of the nerves
distributed to them, entertain the highly probable opinion that they are the analogues of
the antennæ of hexapod insects, and in accordance with this view of the subject M. La-
treille termed them chelicera; but so widely do they differ from antennz in structure and
function, that the propriety of bestowing upon them a distinct appellation which does not
imply anything hypothetical will scarcely be questioned: I propose, therefore, to name
them falces. |

Much of the misapprehension that exists among arachnologists relative to the falces
has been occasioned, in all probability, either by the prevailing belief that spiders are
destitute of a labrum, or by mistaken notions as to its precise situation. That they pos-
sess the organ in a low state of development is undeniable, as I have distinctly observed
it in species belonging to the genera Lycosa, Dolomedes, Salticus, Thomisus, Olios, Dras-
sus, Clubiona, Ciniflo, Agelena, Tegenaria, Celotes, Theridion, Linyphia, Epéira, Dysdera
and Segestria t. It is attached by its base to the superior surface of the palate, but the
extremity, which is free and usually round or somewhat pointed, can be slightly elevated,
depressed, extended, retracted and moved laterally at will. To apply the term mandibles
to organs originating above the labrum, and therefore not situated within the mouth,
must evidently be erroneous; and I venture to anticipate, upon anatomical considera-
tions, that future investigations will lead to the conclusion that the mandibles of the

Araneidea are confluent with the palate.

VI. On the (Economy of a new Species of Saw-fly. By Joux Curtis, Esq., F.L.S. $c.

Read January 15, 1850.

THE general attention which is now paid to Natural History almost daily brings to light
some hidden treasure to interest the public and satisfy the inquiring mind. The subject
of this communication appears to be one of these novelties, for a knowledge of which I am
indebted to a friend who has lately been admitted a Fellow of the Linnean Society.

The insect alluded to belongs to the family Tenthredinide, a group of Hymenoptera so
different in ceconomy from the rest of that Order, that some entomologists have been
inclined to separate it from the aculeate families. In general habits the Saw-flies resemble
the Lepidoptera in their second or larva-state, usually feeding on the leaves of plants; but
there are many instances of their living on the pith in the stems of shrubs *, in fruit t,
and evidence is not wanting to lead to an opinion that some are parasitical +, whilst others
form galls §. | ;

. It is not my intention now to enter farther upon these curious anomalies, but to give
the ceconomy and descriptions of the species before us, which I propose naming, in honour
of its captor, Viscount Goderich,

SELANDRIA ROBINSONI.

On the 19th of June, 1848, Lord Ripon’s gardener at Putney, Mr. Joseph Jerwood, sent
me, by the request of Lord Goderich, forty or fifty caterpillars the size of those figured,
which for two years had devoured the leaves of the Solomon’s Seal; eating enormous holes
in them, and leaving only portions of the fibres, as exhibited in the drawing (fig. 1). During
the present year Lord Goderich forwarded to me the following memoranda :—

* Three years ago (1846), about the month of July, I observed that the only plant in
our garden of Solomon’s Seal (Convallaria multiflora, L.) was completely covered and
almost entirely devoured by larvee, which I easily perceived must belong to the family of
Tenthredinide. They had at that time almost consumed the entire membrane of the
leaves, and many of them were even feeding on the stalks. In a short time after, they
had eaten the plant nearly to the ground, leaving only the stronger branches. They did
not appear to touch any of the surrounding flowers or foliage, but upon the Solomon’s
Seal they were extremely numerous, amounting I should think on one small plant to full

one hundred. i
“ The next year they re-appeared.in the same numbers, and then, being much struck by

the circumstance, I sent you some specimens, which I believe were dead before you got
them, owing to your absence from home. Last year they again appeared, and I then sent
you those from which you have so fortunately been able to obtain the perfect fly.

“I have not, as you know, been much at this place of late years, and therefore it is
possible they may have existed here before 1846; but I am sure when I was more at
Putney, from 1840 to the end of 1843, there were none of them to be found, although the
plant was then in the same place as at present. They have never killed the plant, although
they have often eaten up all its leaves and tender fibres. It is now the 8th of June, and
none have as yet shown themselves this spring.” kt à |

By a subsequent letter, however, I find that on the 14th Lord Goderich noticed them,
but in smaller numbers than in previous years. —

The caterpillar has 22 legs, viz. 6 pectoral, 14 abdominal, and 2 small anal feet: it is
of a pale greyish green, shagreened, with very narrow transverse folds, and there is a slight
tint of ochre about the fourth segment and towards the tail, with an indistinct greyish line
down the back: the head and six horny pectoral legs are deep black and shining : there is
à double row of minute black dots down the back, formed of short spiny tubercles, with
à row of similar dots down each side, as well as along the spiracles, which are black, and
the folds of the thighs are freckled with minuter spines (2, 2): the trunk or fore-part looks
dilated when viewed from above; these larvæ were nearly $ of an inch long on the 28th
of June, when many of them had cast their last skins, which were left sticking to the
leaves (fig. 3), and they disappeared in succession, burying themselves from 2 to 4 inches
deep in the earth, where they formed small oval cocoons like a coating of glue, but often
perforated in places (fig. 4).

In the present year I had the satisfaction of breeding a male fly on the 30th of April;
on the 3rd of May another hatched, and also two females, and these were succeeded by
several more of the latter sex which emerged from their tombs. They were as black as
` ink, and appear to be allied to Selandria Juliginosa of Schrank; but the male antenne»

wings are entirely black, with the costa and stigma thickened and darker, as well as the
nervures, the surface being iridescent; the superior (fig. 8) have two marginal and four
submarginal cells; the first minute, the second twice as large, the other two very large,
the third receiving the transverse nervures which divide the marginal and discoidal cells;
the inferior have only one discoidal cell (fig. 8*): the legs are moderately stout and
pubescent; the tibiæ are spurred at the apex, the spur of the anterior pair notched af the
apex ; tarsi 5-jointed, the first four lobed beneath; the last joint terminated by two bifid
. testaceous claws and simple pulvilli (fig. 9).

Although the elongated antennæ of this Selandria resemble those of Nematus, and still
more those of Cladius, this species is not only distinguished from those genera by the
divided marginal cell, but the heavy habit of the females especially shows at once the
groups to which it is naturally allied, and these affinities are supported by its trophi, which
are intermediate between Athaliat+ and Tenthredot. I may observe that the number of
discoidal cells in the inferior wings varies in the species of Selandria, a character hitherto
unnoticed, but which may supply admirable distinctions for reducing the genus into sec-
tions. 1st, Those with two discoidal cells, the marginal cell receiving one transverse
nervure, of which S. serva, Fab., is an example (fig. 13). 2ndly, S. stramineipes, Klug,
in which both transverse nervures are united with the marginal one (fig. 14). 3rdly, Those
with one discoidal cell, as shown in S. Robinsoni (fig. 8*) ; and 4thly, Those having no
discoidal cell, as in S. fuliginosa, Schr. (fig. 15). The variations in the position of the
nervures and the magnitude of the cells will also be found very useful in identifying the
species ; and although occasionally the nervures are not symmetrical, and occasionally the
recurrent ones are wanting, such exceptions will not invalidate the divisions I have traced,
but will, I trust, lead to a more careful investigation of this fine and interesting family.

VII. On the Family of Triuriacex. By Joun MiERs, Esq., F.R.S., F. L.S. fe.
Read April 2 and 16, 1850.

Ir is now about nine years since I offered to the notice of the Linnean Society the descrip-
tion of Triuris hyalina, which was honoured by a place in its Transactions *. Upon that
occasion, after giving the details of its structure, I remarked, that as it could not be
referred to any known natural order, it might be received as the type of a distinct family,
Which I suggested as holding a place near Fluviales, or Burmanniacee, but whose positive
rank in the system could not be known until we obtained some information relative to the
structure of the seed and its embryo f.

The subsequent discovery, by my much lamented friend Mr. Gardner, of a very analo-
gous plant with female flowers only, differing in no respect from Triuris, except in having
six divisions instead of three in the perianthium, and in a more lateral and less pointed
style, supplied an interesting fact; but as its carpels were not in a more advanced state of
development, it afforded no insight whatever into the structure of the seed. That inde-
fatigable botanist, whose recent loss we must all greatly deplore, in the paper he presented
to the Society on this subject 1, offered several speculations upon the affinities of his plant
and of Triuris, tending to show, as I will prove, erroneously, that they were allied to Smi-
lace? ; and upon such unestablished data he drew out § a diagnosis of the family I had
previously suggested. In that memoir he stated, that in juxtaposition with his plant he
found another of similar size, presenting a single petiolar blade, much resembling the leaf
of a Cissampelos ||. Although he failed in tracing any underground connexion between the
roots of these two plants, he concluded too hastily that the one appertained to the other,
and hence he inferred that his plant was related to Menispermacee or Smilacee. He
offered at the same time an opinion, that I had overlooked a similar distinct leafy append-
. age in Triuris; but this certainly was not the case, for on quitting the Organ Mountains
in 1838, I carefully gathered all the specimens I could find, with the soil and moss attached,
keeping them well moistened for two months, until I embarked for England, hoping to
witness a further development of the ovaria: at the same time, I examined the moss for
any remains of seed or seed-vessel of previous growth: and hence I feel assured that had
any such leafy appendage existed in connexion with Triuris, it could not have escaped my
frequent and searching observation. The stem of T'riuris, in the living state, is quite hya-
line and transparent, appearing composed of simple cellular tissue, without any visible
longitudinal vessels, except toward the centre, where it is somewhat more compact. On
comparing Mr. Gardner’s plant with Zriuris in the dried state, both exhibit a similar struc-
ture, appearing quite translucent externally, with central darker axile lines. The stem of

the leaf, however, offers a very different appearance; it is far more opake, not darkened in `
the centre, but altogether traversed by numerous longitudinal vessels, which can be traced
distinctly in continuity with the radiating nervures of the leaf-blade: this blade has the
same texture, similar nervures with finely reticulated venations, even to the same peculiar
excurrent free veins terminating abruptly in the centre of all the areoles, and the midrib
is excurrent in a long mucronate point, as in the leaf of a Cissampelos. Again, the mem-
branaceous tubes that surround the base of the petiolar support do not exist in the plant
allied to riuris; these sheaths consist of a simple cuticle with lacerated margins, without
nerves or veins, but marked by several parallel lines, which under a lens are seen to be
those peculiar ducts formed of dotted spiral walls so frequently seen in the Menispermacee,
and of which no signs are visible in the accompanying plant, or in Triwris. The inference
hence is irresistible, that the leaf-bearing stem has no connexion with the singular plant
that accompanied it, and that it is only a young seedling of some other plant, probably of .
a Cissampelos. It has been necessary to be thus precise upon a point involving the validity
of all Mr. Gardner’s views regarding the affinities of Triuris.

Under these circumstances, the name of Peltophyllwm can apply only to the Menisper-
maceous plant, and not to the other, for which a new appellation must now be given. As
it differs from Zriwris only in having six instead of three segments to its perianth, the
name of Hevuris appears the most appropriate; and in order to retain the name of its
discoverer in connexion with it, I propose to call it H. Gardneri. Its generic character
may hence be reformed as follows :—

‘Three years subsequently to the presentation of Mr. Gardner’s paper, a memoir by Cap-
tain Champion appeared *, describing two plants which he had discovered in Ceylon, one
of which was evidently allied to the Sciaphila of Blume, and both of very analogous struc-
ture to the foregoing genera. These, soon after his arrival in Ceylon, he had shown to

MR. J. MIERS ON THE FAMILY OF TRIURIACEA. 45

Mr. Gardner, who at first was much struck with their resemblance to Triuris and his Pel-
tophyllum ; but on account of their manifest affinity to Sciaphila he renounced that idea,
and in some observations which he annexed to Captain Champion’s memoir, he suggested
their position as being in Artocarpee, that being the station assigned to Sciaphila by
Endlicher. Captain Champion, on the contrary, was more inclined to place them in Urti-
cace@, among the Moree, because of their aggregated carpels on a common receptacle.

The first. plant described by Captain Champion is the Hyalisma ianthina; it greatly
resembles Triuris hyalina in habit, and agrees with it, and with Hevuris, in being dicecious.
The perianthium is cup-shaped at its base, with the border divided into eight pointed seg-
ments of equal size, being valvate in estivation, with the apical points inflected in a ver-
tical umbilicus. The male flowers have four stamens placed opposite each alternate seg-
ment, and almost sessile upon a fleshy prominent disc, as in Triwris; but the lobes of the
anthers, instead of being distinct, are here confluent, at first four-celled, but afterwards
bursting into two valves, by a transverse line across the apex on one of the cross pollini-
ferous dissepiments. The ovaria are numerous and aggregated in the female flowers, but
the style, instead of being subterminal and sublateral, as in Triuris and Hexuris, is here
nearly basal upon the ventral face. The whole plant, as in those genera, is covered with
prominent vesicles, forming a bullulato-cellular epidermis. The more important con-
sideration of the structure of its seed will be noticed in a subsequent page.

The second plant described by Captain Champion, under the name of Aphylleia eru-
bescens, is very similar in general habit and structure to Hyalisma ianthina, differing only
in the number of the segments of the perianthium, which are six, as in Sciaphila, with six
stamens opposite to them in the male flowers. The carpels in the female flower do not
differ much from those of Hyalisma, excepting that the style is shorter and ciliately fringed,
not long, simple and pointed. In all the pistilliferous flowers I have seen they are con-
stantly somewhat polygamous, with three or fewer stamens, placed opposite the alternate
segment, among the outer row of carpels; but whether they are polliniferous or other-
wise, I have not been able to determine. The structure of the seed is exactly that of Hya-
lisma.

In Sir William Hooker's herbarium I found a plant of Mr. Cuming's collection from

the Philippine Islands, that bears a great resemblance to Aphylleia erubescens: like it,
the perianthium is 6-cleft, but the segments are not altogether glabrous, being furnished
within at the apex with a tuft of long articulated hairs, and the stigma is radiate with
similar cilia. I have noticed that all the flowers here are hermaphrodite, the three sta-
mens being intermixed with the carpels, as in Captain Champion's plant above mentioned.
The fruit is utricular, and of similar structure.
In the same herbarium is another plant, found by Purdie in Venezuela; it agrees with
the two plants last mentioned in the form of its perianthium, and in having its flowers
hermaphrodite, that is to say, with only one or-two stamens, placed on the margin of a
clustered heap of carpels: here, however, the segments are alternately somewhat narrower,
the broader segments only having ciliate margins, but all are furnished at the apex inter-
nally with long articulated hairs, and the segments, as well as the braets and bracteiform
leaves, are marked with long red spots, as in the two preceding species.

46 MR. J. MIERS ON THE FAMILY OF TRIURIACEE.

From these facts we may safely conclude, that neither the Aphylleia of Champion, nor
Cuming’s speeimen from the Indian Archipelago, nor Purdie’s from Venezuela, differ gene-
rically from the Sciaphila tenella of Blume, a very similar plant from Java, long before
described in the ‘ Bijdragen’ of that celebrated botanist.

Being compelled to impugn the accuracy of the observations of others, it is essential
that I should detail minutely those facts which alone can guide us to a knowledge of the
true affinities of these singular plants, and I therefore proceed to describe the structure of
the seed, as I have found it in Sciaphila. Captain Champion, in the memoir above quoted,
figures and describes the embryo as a comparatively large body lying across, and near the
vertex of the albumen, with a pointed radicle as long as the cotyledonary portion; but the
whole seed, he says, “ is so minute, and difficult of dissection, that it is hard to say whether
the cotyledons are one or two;” the radicle, he adds, “is slightly curved, and pointed
towards the hilum; the albumen, which is originally liquid, becomes hard as the seed
ripens, and usually causes the testa to burst on the side opposite the raphe.” Gardner
adds, “ The radicle is short, conical, and of a brownish colour; the cotyledons elliptical,
compressed, and white ;” the embryo lies “ on the outside of a thin fleshy albumen, or but
slightly covered with it, on the side of the seed opposite the raphe, nearly straight, and
with the radicle directed towards the hilum,” which he states to be on the dorsal face of
the seed. The albumen, which according to Gardner is “fleshy,” is said by Champion to
be somewhat “ corneous ” in Hyalisma, and “ rather hard” in Sciaphila. It is remarkable
that such circumstantial details are not only inconsistent with each other, but decidedly at
variance with the structure of the seed, as I have observed it.

My observations upon the seed of Sciaphila are to the following effect. The outer coat
is a distinct utricle, composed of cellular tissue with intervening merenchyma, the inner

the outer surface formed of large, prominent, sub-

obovoid body, connected only by
body, in the dried state, is marked by several (ab
longitudinal ribs, with intervening hollow spaces, whi icular and transp

guished, nor any mark of hilum, as described by Capt. Champion. The inner space is
wholly filled by a translucent, hyaline nucleus, of so firm a texture, that the hard testa
may be broken, without rupturing it; it is quite free, or perhaps connected by a mere
point, at the apex of the testa. This nucleus is covered by a thin transparent integu-
ment, which is marked with large and somewhat longitudinally hexagonal reticulations,
through the areoles of which are seen a number of included spherules of small size, and
on making sections in different directions across this nucleus, it will be found to consist of
an aggregation of homogeneous, spheroidal, or rather angular cells, which, by pressure,
exude a transparent oil, and a quantity of most minute dark grains of solid matter: the
cells appear all of equal size, and this arrangement was found to be constant in upwards
of thirty very careful sections in various directions, sometimes in clean longitudinal slices
cut parallel with the axis, or transversely, by which the whole internal structure was made
distinctly apparent : these again were subjected to the compressorium, and examined under
the simple and compound mieroscope of considerable power, but every effort to detect the
slightest indication of a distinct embryo, or even to find one cell darker or larger than the
others, has completely failed. "The uniformity of these results, obtained from the seeds of
the two species of Sciaphila, those of Hyalisma, and also of another genus yet to be
described, warrants the conclusion that the nucleus, in all these cases, is deficient of an
embryo. The fact that the seeds thus examined were nearly, if not entirely, ripe, is indi-
cated by the bursting of the utricular covering, and their detachment in many cases from
their basal support, both in Seiaphila and Hyalisma, as well as by the hardness and deep
colouring of the testa, and the firmness of the nucleus.
The genus Seiaphila may be characterized as follows :—

This plant is from 4 to 8 inches in height; the stem is slender, erect, and often flexuose.
Capt. Champion states that the flowers are generally monecious, but his specimens are
all, without exception, distinctly dicecious. The leaves and bracts are a line in length; the
capillary pedicels 4 lines long, the male flowers 14 line, the female 2 lines in diameter; the
stamens are fixed upon the margin of a somewhat quadrately conical roundish receptacle,
very analogous to that of Triuris, from which genus Hyalisma differs in the form of its
anthers, the cells of which are here confluent. It is very easily distinguished from Scia-
phila, by the extreme length of the persistent style, and its much longer pedicels.

Among the specimens recently sent from Pari by Mr. Spruce, is one much resembling
the foregoing plants. The stem is in like manner simple and erect, the flowers spicate
and moncecious; the perianth is however here 4-cleft, with only two stamens in the male
flowers: in the female the carpels are very numerous and densely aggregated, with a lateral
and basal style, as in Sciaphila. The fruit is of the same shape, but is not utricular, as
the pericarpial and endocarpial envelopes are glued together with woody matter, and are
separated, with some difficulty, from the crimson-coloured testa, which, together with the
included nucleus, coincides with that above described of Sciaphila. I have proposed for
it the name of Soridiwm, from coeds, because of its aggregated carpels.

At first sight this plant bears much the habit of Dietyostega orobanchoides. Its rhi-
zoma appears somewhat stoloniferous, and to creep along the ground, throwing out at
short, intervals bunches of long hairy rooting fibres, each fibre springing out of a small
eupuliform node, thus showing its endorhizal structure; the prostráte intervals are of the
same thickness as the culmiform portion, and bear similar bracteiform leaflets. The spike
occupies one-third of the length of the single erect stem, which is slender, sulcated, some-
what flexuose, and from 8 to 10 inches in height; the leaflets are few, and mostly towards
the base; they are linear, pointed, 11 line long. The bracts are also linear, about the
length of the pedicels, 1 line long; the flowers expanded measure 2 lines in diameter; the
ovaria are from twenty to thirty in each of the female flowers, of which there are from five
to seven at the lower portion of the spike. Although the pericarpial and epicarpial cover-
ings of the seed are here glued together into one coriaceous mass by the deposition of
woody matter, yet upon making a longitudinal section, the same nervures, basal support,
and apical strophiolar process, that form so conspicuous a feature in the arilliform cover-
ing of Sciaphila, may here be distinctly traced, and the darker-coloured basal support, and

rescence, unisexual flowers, simple perianthium, similar in both sexes, nearly cleft to its
base into regular segments, with a valvate sestivation and a cellular epidermis ; the male
flowers furnished with few stamens, which are seated opposite the segments upon a fleshy
disc, or more or less prominent androphorum ; very numerous distinct carpels in the female
flowers, having a more or less lateral style, and a single erect ovule, and offering a seed of
most peculiar structure. These characters do not conform with any other natural family ;
for which reason, when Triuris only was known, I suggested it should form the type of a
new order. In regard to the affinities of this group of plants, it is manifest that they
bear:no analogy with Menispermee or Smilacee, as Mr. Gardner at first inferred; nor can
they be held related to Artocarpee, where that zealous botanist, following the example
of Endlicher, referred Sciaphila and Hyalisma. Their structure, totally different habit,
simple style, erect ovule, arilliform envelope, and acotyledonous seed, distinguish them in
the most decided manner both from Artocarpee and Urticeæ. In order to arrive at their
real position in the natural system, we must first determine in what class to seek their
" nearest alliance.

The facts before shown lead to the inference, that the seed of the Z'riuriacec is not only
acotyledonous, but inembryonal, a fact not singular in the history of Phænogamous plants.
But does the absence of the usual elements constituting an embryo, viz. cotyledon, radicle,
and plumula, imply the want of the ordinary function of the reproductive power of the
plant from its seed so constituted ? It appears that the presence of such elementary parts
is not always a necessary condition to the capacity of vegetable reproduction. According
to the views of modern physiologists, the embryo is but a normal condition of a leaf-bud
and stem, whose gradual increment is due to certain secretory deposits, regulated by fixed
laws of cellular expansion, thus producing a highly complicated or low degree of vascular
development in every phænogamous plant, from the smallest herb to the most gigantic
tree of the forest. But in those plants destitute of real leaves, and composed of little more
than simple cellular tissue, void of green colour, and of the fibres and ducts that enter into
the structure of most other vegetable substances, we can hardly expect to meet with a
reproductive embryo organized in the form of such a normal bud; and it is only consist-
ent with so simple a structure, to expect a nucleus equally simple in its nature, formed
merely of an aggregation of eytoblasts, which, under favourably-exeiting influences, are
endowed with the faculty of self-development. Indeed, we have no satisfactory evidence
of the existence of an embryo, in the ordinary sense of this term, in the seeds of Burman-
niacee, &c., notwithstanding that we know they must be constantly reproduced from their
seeds.

Mr. Robert Brown, in his learned memoir upon Rafflesia, in the nineteenth volume of
the Society's Transactions, has shown that the seeds of that genus, although albuminous,
possess an embryo of the most simple and reduced form ; but the Balanophoree, which
that most distinguished botanist holds to be quite a distinct and even distant family from
the Rafflesiacee, have been shown by Mr. Griffith to be truly inembryonal; and in his
paper on Balanophora * he describes the structure of its nucleus, and the contents of its
cells, as being precisely similar, even in words that answer ın every respect for all that is

* Trans. Linn. Soc. vol. xx. pp. 98, 101 and 102.

seen in Seiaphila, Hyalisma, and Soridium, and the figures he gives of it* quite corre-
spond with the details now offered of the seminal nucleus in these genera. Prof. Lindley
has long contended that these two families belong to a distinct class, which he calls Rhi-
zanths or Rhizogens; but Mr. Griffith, in his able memoir above-quoted, wholly accords
with Mr. Brown’s views on this subject, and states that these plants, though with inem-
bryonal seeds, or with what he calls a homogeneous-embryo-form structure, may, without
violating the rules of classification, be considered as aberrant forms of an imperfectly
developed state of exogenous or endogenous organization. Thus, Mr. Brown has always
considered the Rafflesiacee to be allied to the Aristolochiee, and Mr. Griffith contends
that the Balanophoree should be placed near the Urticee.

The considerations before stated naturally lead to the inquiry, if in such plants no em-
bryo exist, using that term in its ordinary signification, how is their propagation effected
by a seed with a simple nucleus of aggregated cells? According to the views of most
modern physiologists, the earliest development of an embryo within the ovule is the forma-
tion of a germinal vesicle (primordial utricle of Mirbel), generated by the action of the
pollen-tube upon the embryonal sac, and the degree of perfection in the organization of
the cotyledon, radicle, and plumula, is evidently proportioned to the function requisite to
the future elaboration of the leaves, or a more or less complex stem; but in the case of
leafless plants, the same amount of development would be useless for so simple an economy
of structure. This is even seen in plants of a very high degree of floral development, as
in Cuscuta, for instance, where the embryo of its seeds is altogether deficient (apparently)
of the usual requisites of cotyledons, radicle, and plumule f, as it consists of a simple
spiral thread, not germinating in the usual manner from two fixed points, but from which
pullulating vesicles are produced, indifferently from any point of its surface, thus proving
that the organization of the embryo bears an evident relation to the economy of the future
plant. The Orobanchee also present a very small undivided embryo, and the Monotro-
pee have a minute nucleus, in which neither cotyledon nor radicle is perceptible; and this
is included in a reticulated arillus, as in Burmanniacee. Another instance, still more
striking, oceurs in Cactee, where in the leaf-bearing genera the cotyledons are fully deve-
loped in the embryo, while in the leafless species the embryo is solid and undivided. In
the same manner it is probable that in the Burmanniacee, Balanophoree, Triuriacee, &c.,
tha inembryonal nuclei, consisting of a series of germinating cells or cytoblasts, pullulate
ak certain points, and thus perform all the requisite purposes of reproducing their very
simple forms of structure, in a somewhat analogous way to that in which the ordinary.
embryo effects the more complex organization of vascular fibres and elaborate tissues in
the higher orders of Phænogamous plants,

If we admit the existence of’ an organ, thus endowed with the function, but wanting

the usual structure of the embryo, it should hold some adequate designation, and for this

the term Protoblastus does not seem inappropriate, as it effects the same purpose as the

— or plumula f. The word used by Mr. Griffith for this organ, * homogeneous
embryo, would require that the ordinary embryo, in contradistinction, be called hetero-

. geneous, which would not accord with its nature; but if these denote only different con-
ditions of the embryonary form, the one may be considered as a protoblastous, the other
as a cotyledonous embryo. On surveying other peculiar embryonal forms, some will be
better understood by this view of the subject ; for instance, we may conceive that the pro-
toblastus, instead of forming one compact mass of spherules, as in Balanophoree, Triu-
riaceæ, &e., may be somewhat less aggregated, so as to assume the shape of elongated
bundles of cells, such as have been termed paraphysiform : such a form is actually met
with in Ceratophyllum, where the exterior series of unequal size have been assumed to be
an unusual number of cotyledons, and the very numerous inner series have been held to
be a highly developed plumule, while the common. point of their union is considered
as the radicle. The development of this embryo has been well analysed by Schleiden,
in his memoir on Ceratophyllum *. Professor Lindley remarks t, that “in this instance,
as in Nelumbiacee, the highly developed plumule may be a compensation for the want
of albumen, enabling the embryo to germinate without assistance, as soon as it is ex-
posed to the fitting conditions.” The leaves of Ceratophyllum appear destitute of all
nervures, consist of confervoid parallel cells, and dichotomously divide themselves into
simply articulated hair-like segments, thus denoting a lower order of development than
has been assigned to it. Independently of this cellular texture, we must bear in mind
that this genus possesses moncecious flowers, with a simple perianth, having a valvate
æstivation, almost sessile stamens, an unilocular carpel with a solitary ovule ; and if,
in addition to these characters, we regard the construction of its embryo, in the view
above contemplated, its position in the system would rank near Flwiales, as was long
ago suggested by Bernard and Antoine de Jussieu, followed by Jaume St. Hilaire and
Agardh, and therefore, as will be seen, not far from Triwriacee. Conterminous with the
Fluviales we find another family, the Aroidee, which offers many circumstances bearing
upon this subject. Blume describes Amorphophallust as possessing an exalbuminous
simple nucleus, homogeneous in texture, with one of its extremities pullulating at one,
two, or three points, and throwing out fleshy lobes, which overlap each other. The same
botanist records, that in Aglaonema the seed has a solid nucleus, which, in germination,
throws out several squamulæ at one end $; and Schott states that the nucleus of Crypto-
coryne emits several gemmulæ in a similar manner|. This fact has been confirmed
and illustrated in an admirable manner by Mr. Griffith, in a very interesting
memoir upon Ambrosinia (Cryptocoryne) ciliata], where he has shown, that at an early
period the ovule presents an embryo, which then appears to be quite homogeneous, and
“ entirely cellular,” and that its development is first marked by the production, upon a

small area of its surface, of several minute oblong cellular bodies, which soon enlarge, :
others in great numbers being successively formed in their centre. These rudimentary
processes soon become more and more elongated, their growth being very rapid, until they
acquire five or six times the length of the original globular nucleus, from which, when
fully developed, they finally detach themselves, the nucleus remaining enveloped in the
swollen integuments. This new production thus assumes the form of a large plumula,
still more highly developed than that of Ceratophyllum, and separates in the manner above
described, as the germ of a future plant, consisting of an immense number of subulate
thread-like processes, at least an inch long, which are furnished with vessels, but their
chief bulk is cellular, the cells containing a number of green globules. Mr. Griffith re-
marks, that the cells of the nucleus, as well as of the processes, in an early stage of their
development, abound in active molecules, possessed of an exceedingly rapid oscillatory
motion; and it is obvious, from the universal presence of these corpuscles during the
formation of tissue, that they play an important part in this most obscure process. Mr.
Griffith considered the nucleus to be the cotyledon, the processes as forming a plumula,
and the neck, which united them at base and which is seated upon the globular cotyledon,
to be the radicle; but these parts do not seem to bear any analogy to such elementary
portions of the ordinary embryo of phzenogamous plants, as is evinced by the quite unusual
position of what is here considered a radicle, between the cotyledon and plumula, and by
the fact of the detachment of such cotyledon, which has always been held to be necessary
to the completion of the germinating functions of the radicle and plumula. Mr. Griffith
endeavoured to explain these contradictions by ingenious reasonings, which, however, are -
far from being satisfactory, as he was forced to acknowledge that this case forms a re-
markable exception to the general law of the absolute necessity of a cotyledon in a distinct
embryo, and that it is only to be accounted for on the plea that the presence of such a
highly developed plumula obviates that necessity. These anomalies, however, appear to
"M Pues satisfactorily explained by considering the original nucleus in the light of a
mee — from which a certain number of its cells, animated by the oseillatory
3 of the active molecules, as described by Mr. Griffith, pullulate and attain a rapid

increment, by the production of a number of thread-like cellular processes (or protophylla)
united at their base by the common centre of the original germinating cells (or epiblast).

The plumula of Griffith may thus be considered,simply as an aggregated bundle of proto-

phyls, destined to form the germs of future leaves; and his radicle may be viewed merely
as an epiblast, which, however, performs all the functions of a radicle, by subsequently
generating from its former point of attachment other cells to constitute future rooting

fibres; and his cotyledon remains only the original protoblast, which having thus performed

its function of elaborating a gemmiferous prototype, becomes detached from its offspring.

Under this point of view the embryo of Cryptocoryne may be considered as protoblastous,

and not as cotyledonous, and the anomalies above Shown vanish without calling in aid

be compared with the arilliform covering above described in the genus just mentioned.
The embryo of Pistia is cylindrical, nearly half the length of the albumen, in the summit
and in a longitudinal cavity of which it is placed, with its apex quite bare, the whole being
enveloped by a thin pellicular integument, and this again by a thin and somewhat coria-
ceous reddish testa, marked much after the manner of that of Soridium. This testa is
fixed upon a long, thickened, stipitate support, and is crowned at its apex by a dark
pulvinate process, suspended by a cylindrical plug or strophiole, the point of which is seen
in the umbilical apex of the seed. The external covering is a thick, wrinkled, fungous or
pithy substance, lined inside and outside by a thin adhering membrane, and enclosing the
stipes, the testa and the strophiole, and it can be considered in no other light than an arillus,
and as analogous to the peculiar covering of the testa seen in Sciaphila. In the Zingibera-
cec the seed is also covered by an arillus somewhat similar to that of Pistia, while in Rave-
nala, by its numerous ribs, it approaches yet nearer to the seminal envelope of Sciaphila;
here, however, as well as in Pistiee, the albumen is of peculiar structure, being farinaceous
when dry but becoming distinctly cellular when moistened, and the cells are separable
from each other without bursting; they are then translucent, and bear altogether a very
different aspect from those seen in the nucleus of Sciaphila, in which they are more
opake, as if filled with dark grumous matter. The facts here brought together are inter-
esting, as presenting some analogies bearing upon the question, and they serve to show
that we have yet much to learn concerning the nature of the more simple forms of em-
bryonal structure, and of the functions of reproduction.

In respect to the position of the Triuriacee in the system, if we follow the rules of
elassification founded upon the three great divisions of Acotyledonous, Monocotyledonous,
and Dicotyledonous plants, a plan now quite untenable, they must of course range in the
same group as the Balanophoree, although they hold but little relationship with them. But
if we regard the condition of the embryo, not as a basis, but merely as a frequent indication
of the three great divisions, founded on the structure and development of vegetable fibre,
viz. Acrogens, Endogens and Exogens, and if we accord with the views of Mr. Brown and
Mr. Griffith, in considering what the latter calls the homogeneous-embryo-form state of
the seed merely as an imperfect condition of development, common alike to all these
groups, then the Triuriacee must take their place among the Endogens.

Here, the family that at first sight appears most approximate is the Alismacee, with
which the Triuriaceæ agree, in their simple stem, sometimes spicate unisexual flowers,
and their numerous carpels; but Alismacee differ in having leaves with parallel HERVOR,
in their floral envelope being distinctly biserial, tlie outer calyeine, the inner petaloid, and
both with imbricated æstivation ; they are also dissimilar in their bilocular anthers, with
parallel cells, dorsally affixed to long filaments ; ovules often two in each carpel, Sue being
superimposed ; carpidia opening by their ventral suture, and seeds with large hippocrepi-
form embryo. : ^

With Fluviales, Triuriacee accord in their soft cellular structure, their moncecious
flowers, simple perianthium with valvate æstivation, often 4-locular anthers, several

the plants of this family differ wholly from the Triuriacee, in having distinct, entire,
large leaves, with long amplexicaul petioles, and intrapetiolar vaginant stipules, in their
female flowers arising from the superior axils, in the frequent absence of any perianthium,
ovules often suspended from the ventral suture, and very delicate membranaceous testa.
Their exalbuminous macropodous embryo may be considered as an approximation to the
structure of the nucleus of Sciaphila.

With the Juncaginee they agree in their inconspicuous spicate flowers, numerous
carpels, with a solitary erect ovule and exalbuminous seeds; but these again differ in their
large leaves, with parallel nervures, 2-serial floral envelope, extrorse stamens upon long
filaments, and sometimes two ovules in each carpel. The Juncaginee, however, have been
considered by some as a suborder of the Alismacee, by others to be more nearly allied to
Fluviales and Aroidee, on account of their spicate flowers: indeed, though placed at so
great a distance in the system by Endlicher, they are really so closely allied, that the
genera Ruppia and Potamogeton are placed by some botanists in Fluviales and by others
in Juncaginee.

If we agree in placing these four families in closer juxtaposition in the system*, the
Triuriacee will find a place near them; but, upon the whole, the greatest amount of
approximative characters will be seen to lean towards the Flwviales, especially through
Potamogeton (which genus is arranged by Mr. Brown among the Alismacee), and which
possesses a simple perianth of four segments in a single series, with valvate æstivation,
and four stamens opposite to them, globose simple pollen and uniovular carpels; and
although it bears hermaphrodite flowers, it must be remembered that Sciaphila is some-
times bisexual. Najas and Caulinia, as before observed, present also carpels with a soli-
tary erect ovule. .

It now only remains to define the characters of this small order.

VIII. The Anatomy and Development of certain Chalcididæ and Ichneumonide, compared
with their special (Economy and Instincts; with Descriptions of a new Genus and
. Species of Bee-Parasites. By GEORGE Newport, Esq., F.R.S., F.L.S. Sc.

Read March 20, 1849.

Preliminary observations.

THE parasitic Hymenoptera include, in their larva state, some of the most imperfectly
organized conditions of life to be found in the whole of the Articulata. They leave the
ovum delicate, apodal, almost motionless, and entirely incapable of locomotion, and are
injured and perish by slight accident, as an abrasion of surface allows the fluids of their
bodies to escape quickly and fatally by the wound; and yet these very beings, having
passed unhurt through this scarcely other than foetal condition, acquire a perfection of
organization, a degree of activity and power, and an acuteness of instinct, fully equal, and
perhaps superior to the organic and the functional endowments of other tribes of insects.
One section of them,—some of which I shall make the subjects of this paper,—are nourished
entirely by suction, and’subsist on the fluids of other insects; and either attached singly
to the external surface of the bodies of their victims, or, located internally, between the
tissues, they drink up the life-blood prepared for another, without entirely destroying the
means of its production. Other species are gregarious and reside in the same cell with
their victim; and while that subsists on vegetable food,—pollen mixed with honey and
stored up for it by its parent,—it is attacked on all sides by its insidious enemies, succumbs,
and dies as they become nourished. Yet the general form of body, and of the digestive
organs, at the earlier periods of growth, is almost precisely the same in most of these de-
scriptions of parasite, and the special development of each is regulated by the same laws.
They cast their skin at succeeding stages of growth as certainly as do the larvæ of Lepi-
doptera; but the thrown-off covering is of such extreme tenuity, and is so gradually and
almost imperceptibly removed, without interfering with the form or the enlargement of
the body, that, hitherto, the deciduation of the tegument of the apodal larvæ of Hymeno-
ptera has always escaped the observation of naturalists. I have, however, witnessed its
repeated occurrence in the genus Paniscus, as I shall show in this paper; so that these
species do not constitute, as was supposed, an exception in this respect to one general law.
Much as they resemble each other in external appearance, they do so still more in the
structure of their organs of nutrition, The digestive apparatus in the whole of them is at
first but a simple, capacious sac or bag, rounded and closed at its larger extremity, with
an imperforated intestine proceeding from it, without an anal outlet. It has this form
in most of these insects during the earlier periods of the larva state, when the organizing

62 MR. NEWPORT ON THE ANATOMY AND DEVELOPMENT

powers of the system are most energetic, and when nearly the whole of the food is appro-
priated to the enlargement of the body. Very little undigested substance then remains,
after the assimilation of the nourishment imbibed, and consequently no excretory outlet
to the organ is required. But when the assimilation of food begins to be arrested, and
the rapidity of growth is diminished, as is the case when the larva is approaching its
maturity,—changes which seem to lead to the inference, that the forces of combination in
the primary organisms of the body become less and less energetic in proportion to the
degree of stimulus to which they are submitted,—the digestive apparatus then assumes a
new form: it is narrowed and elongated, and being connected with a column of granu-
lated cell-masses, which, derived originally from the yolk, are continuous with those that
constitute the walls of the digestive cavity at one end, and at the other with the tegu-
ment, the czecal extremity of the sac becomes perforated, and the cells separating in the
axis of the column form a tube, that is quickly lined with epithelial membrane, to allow
the passage of the refuse of digestion, the tegument having previously separated also at a
given point, by which an excretory or anal outlet to the canal is completed. The mate-
rial first removed is composed chiefly of disintegrated epithelial cells, which line the digest-
ive cavity, and are thrown off as they become aged and worn-out, during the elaboration of
nutrient fluid, like the cells which form the cast layers of tegument. This change of struc- :
ture does not take place in any of the parasitic larvee, so far as I am aware, until the indi-
vidual is replete with nourishment, and ceases to feed, preparatory to more extensive alter-
ations of form. When this marked period of its existence has arrived, it is first necessary
that the unassimilated portions of food, together with the worn-out materials of the body,
should be removed, and this necessitates the change from a closed receptacle to a canal.
But further reason for this late completion of the organ, as well in those larv which are
confined to a given space with their food, and in those still more confined between the
tissues of other insects, at once suggests itself. In the one case the food stored up must
remain pure and uncontaminated, for the support of the larva preyed upon; in the other,
the fluids of the victim must not be changed from nutrient to rioxious aliment by the
engenderment of disease within it, through contact with effete matter from the body of
the parasite, and thus destroy what otherwise it would nourish. But the primary object,

the ur maturity of the larva, being attained, the development of the canal is then
completed.

In the month of August 1831, while examining the dry clay bank beneath the ruins of
the Roman castle at Richborough, near Sandwich in Kent, in search of the larvæ of Meloe
in the cells of Anthophora retusa, with which the bank was thickly perforated, I found
many cells filled with an abundance of minute parasitic larvee, about one line in length,
and apparently full-grown; but scarcely a cell contained any vestige of its original inha-
bitant, the larva of Anthophora. During that autumn and the following spring I met
with these parasites so frequently in the cells, in diffepent stages of development, that
although I regarded them at that time as a new species of Chaicidide, I took little heed
of them, as my chief object then was to obtain the Meloés, and as I expected to find them
on future occasions in equal abundance. Indeed they were so common as to occasion me
considerable annoyance in finding the cells filled with these intruders instead of the larvee
of Anthophora or Meloé. I took care, however, to make very precise drawings of both
sexes, in the perfect state, and of the larva, and also entered some notes of description.
In the following years, 1832 and 1834, I again met with them, more especially on the
21st of August in the latter year, but not in such profusion as at first; but I have not
been able to procure them since that period.

The larva (fig. 3) is completely apodal, of a sub ;
extremity, and composed of fourteen segments. The head is small, like that of the wasp,
or hornet, and the mandibles are short and acute. It occurred in the bee-cells to the num-
ber of thirty or fifty in each. I found it not only in the autumn, but also in the winter
and early spring, in this state, but in some cells the larvæ had changed to nymphs before
the month of September. :

I have been unable to find any description in the works of entomologists of this curious
genus of parasites. Mr. Walker, our most assiduous monographer of the Chalcidide, 18
unacquainted with it; and the only naturalist, so far as I can ascertain, who has made
reference to an insect which Possibly may have some affinity with this, is Mr. Westwood,

Who, in his work * published in 1839, mentions a species found by M. Audouin in France,

in the nests of « Odynerus, Anthophora and Osmia,” but he adds that “the species has
not yet been described." Since then he has again alluded to M. Audouin’s insect t, 38

having “singularly distorted antenne, and the wings almost rudimental,” thus offering,
he says, “ a strikingly opposite analogy to other bee-parasites.” But without describing
M. Audouin’s insect, either generically or specifically, or explaining in what its “ stri-
kingly opposite analogy” consists, this naturalist has proposed to designate that insect
Melittobia Audowinii. A name thus given without a description, either generic or spe-
cific, cannot, however, be adopted; even if that insect should ultimately prove to be iden-
tical with mine. The necessity for precise description when a name is imposed will at
once be perceived, in the fact that both Reaumur and DeGeer long ago found Chalcidi-
dous parasites in the nests of mason-bees, and yet, up to the present time, their species
have not been clearly made out. Reaumur * found more than thirty larve of one species,
and in other nests ten or twelve of a larger species. DeGeer + also found twenty speci-
mens of another kind. in a single cell, and which he reared to the perfect state. He re-
marks, too, that the larvæ of mason-bees are very subject to be destroyed in their cells by
the larvæ of different species of Zchneumon. The species found by DeGeer seems to have
been a Pteromalus, or nearly allied to that genus. These facts are interesting, as showing
that mason-bees are infested by many parasites. The occurrence of Audouin’s insect in
the nest of Odynerus, as well as of Osmia and Anthophora, as stated, renders its identifica-
tion with the insect I have discovered very doubtful. I have never found my species in
any other than the nests of Anthophora.

The habits of this insect may be inferred from the peculiar organization of the male.
From both sexes being found in the closed cells of the bee, and from the absence of a long
ovipositor in the female, we may conclude that the eggs are deposited while the nest is
being provisioned, or immediately before it is closed; and that, like the true Ichneumons,
the parent either plunges her eggs into the body of the newly-hatched bee-larva, og
attaches them to its skin. The bee-larva, like many other species similarly arcum-
stanced, continues to feed, and grow, and supply nourishment to the parasites; and by
the timé it has consumed the whole of its provision, these also are far advanced in growth.
When the young bee is entirely destroyed these are matured, and pae for their change
to the state of nymph, which they assume lying loosely in the cell, without spinning sepa-
as rn tance that although both sexes are found moving about freely in the
cell, the male is by far the least active, and especially from the fact that his organs of
; instead of large compound eyes, as in the other sex, I am
| led to the conclusion that impregnation is effected before the insects quit their habitation ;
because ocelli, being different in their structure from the individual parts of the —
pound eyes, are fitted only for near vision. The difference of structure consists in this:
the ER, external surface of each part of the compound eye, which a mad "
perfect, as an organ of vision, as the ocellus, or ee en

of the latter; while the chamber of the eye, or space between the cornea and the termina-

tion of the nerve at the bottom of the structure, is of much greater length in the com-

vision are merely single ocelli,

pound eye than in the single. The result of these two conditions is, that the compound
eye is fitted for viewing objects at à considerable distance, but with little magnifying
power ; while the ocellus has great magnifying power, but is fitted only for viewing near
objects. The male with his single eyes may thus be regarded as acute, but short-sighted,
the very opposite of his partner. But this condition is essential to him, and fully suffi-
cient, if, as presumed, the greater portion of his existence is passed in a closed cell, not
half an inch in diameter, and from which perhaps he never wanders more than to the
distance of a few inches. But stemmata or ocelli only would be insufficient for the other
sex, who has not only to seek out the proper locality for her eggs, but also to elude the
vigilance of the bee in whose nest she is seeking to introduce her own progeny. Instead,
therefore, of mere stemmata, the eyes of the female are multiplied, and occupy, as in most
other perfect insects, a large portion of the surface on each side of the head. Each of
these aggregated eyes has a much greater length of sight, or distance of vision, than is
afforded by the different structure of stemmata; while the multiplicity of these organs at
one spot supplies to the insect at once long focal distance, or long-sightedness ; and their
multiplicity more than compensates for the narrowness of the field of each cornea.

The conclusions, then, which are deducible from the structure of the organs of vision
seem to be, that whenever an insect is provided only with stemmata, the habits of the
species, in that state of existence, are restricted to a few objects or requirements; or that
the species is limited in perception and locality; while, on the contrary, when the organs
of vision are multiplied and aggregated to form what we designate a compound eye, as in
the imago state of most perfect insects, the field of vision, as well as the focal distance, or
length of sight, and with these the range of the insect, are greatly extended.

Other facts in the comparative anatomy of this parasite confirm these conclusions. The
short closed wings of the male, as noticed by Mr. Westwood in regard to the undescribed
insect Mellitobia*, contrasted with the wings of the female, lead us to infer that the
former sex rarely or never employs them in flight, and confirm the opinion that impreg-
nation is the sole requirement for the male, and is effected within the cell.

This condition of the sexes affords a remarkable contrast to that of Stylops, which I for-
merly had the honour of bringing before the notice of this Society, Jan. 19, 1847 t. Inthat
genus, as will be remembered, the worm-like female is sought out by the active male, in
which the organs of vision, as in the equally active males of the Hive-bee and Glow-worm,
are enormously multiplied, yet merely for one single act of existence—the continuation of
the species.

Thus it may be seen that under every form of body, and of each individual organ, the

special anatomy of à Species is an index to its natural history and economy.

The second Chaleididous parasite, which I have found in the nest of Anthophora, is an
insect of different character from the one just described, but equally illustrates the gene-
ral views now proposed.

MONODONTOMERUS NITIDUS.

On the 12th of September, 1847, I detected, in several cells of Anthophora retusa, in a
dry clay-bank at Gravesend, a number of white Hymenopterous larvee, which at first I
mistook for those just described. "There were from twelve to twenty-five in each cell, appa-
rently full-grown, and measuring each about one quarter of an inch in length. "The body,
in these larvee (fig. 7 & 8), was formed of fourteen distinct segments, each divided trans-
versely on the dorsal surface into two, and covered with exceedingly fine, scattered, brown-
ish hairs. The head was small, and provided, as in all parasitic Hymenoptera, with short,
transverse, corneous mandibles, and the larvæ had considerable power of locomotion, by
the extension and shortening of the segments. The whole of the food that had been pro-
vided for the bee-larva was already consumed, and the bee-cell contained only the para-
sites and the dried tegument and head of the young bee, which seemed to have been
starved. It was a question with me whether the bee-larva had not been killed by the
other larve piercing it, and abstracting its fluids from without? This query, then,
seemed to be answered by the circumstance that the number of the parasites was dis-
proportioned to the size of the victim, which, had it served as food for them, would in all
probability have been entirely consumed. Besides which, one anatomical fact showed that
they were external feeders,—their bodies were covered with a few scattered hairs, appre-
ciators of contact; a condition which I have never yet observed in the soft-bodied, inter-
nal-feeding larve of other Hymenoptera, and one which is as little required by them, as it
doubtless would be inconvenient. Added to this, the great power of locomotion pos-
sessed by these larvze,—which is neither possessed nor required by internal feeders, which
remain almost constantly in the same spot,—suggested the opinion that it is on the food of
the bee that these larvæ subsist, and not on the young bee itself, which may perish merely
by deprivation of its proper nourishment. The larvæ also exhibited some indications of the
formation of an anal outlet to the alimentary canal, which are not apparent in internal
feeders at this stage of growth.

I preserved these larvæ, in the cells in which they were found, through the following
winter, and although the remains of the bee were left with them in the cell, it continued
untouched, and they exhibited no further change until the middle of May 1848. At that
time some of the specimens gave signs of approaching transformation, in the shortened
and more shrivelled appearance of their bodies. Each of the larvæ then spun some very
delicate silk, in small quantity. Shortly before they were ready to enter the nymph state,
the alimentary organs became perforated, and fzeces were then passed for the first time
during the whole period of the insect’s previous existence. The fzeces passed were little
solid brown masses, that closely resembled the fzecal masses passed by the pollinivorous
larva of Anthophora, which, like its parasites, as I have constantly found, passes nothing
from its alimentary canal until it is about to change to a nymph. These fæcal masses
seemed to indicate the supposed nature of the food,—pollen and honey ; and to support
the opinion formed of the habits of these larvæ from. some points in their external anatomy.
From twelve to twenty masses were passed by each larva : these were composed of the

refuse of digestion and of epithelial cells accumulated during the period of feeding, and

retained in the digestive sac until the period of its perforation. In this way the food and
abode of the insects are maintained pure and uncontaminated, and the digestive apparatus
is completed, and the refuse of nutrition ejected only when the whole of the food has been
consumed. Thus we find the most perfect concordance between the internal as well as
external anatomy, and the functions and economy of the animal, exemplifying in every
particular the harmony of creation.

I have stated that the digestive cavity is at first a closed sac. This species has enabled
me to demonstrate the fact, and further to illustrate the manner in which it is changed
from this form to that of a tube or canal.

On dissecting this larva, I found that nearly the whole interior is occupied by the di-
gestive apparatus, which has the form of a bag, or rather of a Florence flask (fig. 9). Pro-
ceeding from the mouth and pharynx is a narrow short œsophagus (a), which suddenly en-
larges into the common cavity (5) : this occupies nearly the whole of the interior, and has
extremely thick walls, formed of large packets of granulated cell-masses, inclosed between
an exceedingly delicate muscular envelope on the external surface, and an equally fine, gra-
nulated membrane on the internal. It is divided from the cesophagus internally by a thick
fold of its mucous and celliform tissues, which here constitute a complete cardiac valve (c),
and prevent the regurgitation of the food. At the posterior, or larger end (d), it is con-
nected with a column of cell-masses (d d), which have partially coalesced on the exterior,
in the formation of a fibro-cellular envelope, and which, proceeding backwards, are united
with the common tegument of the body in the fourteenth, or anal segment (f). In the
centre of this segment, on the external surface, the skin and muscles separate at a definite
point in the formation of the anal outlet. "When the change is about to commence, the
cell-masses that form the cæcal end (g) of the cavity also separate and recede, and this
separation extends backwards to the fourteenth ‘segment in the axis of the column of cells.
By the centrifugal expansion of these, and the consequent widening of the tube, the canal
is completed, and quickly becomes lined with a delicate membrane, like the interior of the
larger cavity. The digestive organ is enveloped in a thick layer of granulous matter, in
which the Malpighian vessels (^) and the organs of reproduction are developed. At its
anterior and inferior surface it covers two large sacs, the silk-glands (7). These are the
first developed organs of this class of structure, and are needed thus early for the produc-

tion of the silk which the larva spins before its change.

The nymph state (fig. 11) was assumed by two of my specimens at the end of May. On
the 30th of that month I found that three others also had undergone their change, and that
the remaining ones were preparing to do so. The nymph had the usual form of the tribe,
and the sexes were now for the first time distinguished. The male nymph was smaller, more
slender, and with the apex of the body acute; while the female was much larger than the
male, with a short projecting keel at the posterior of the abdomen—the ovipositor.

The imago (fig. 12).—On the 27th of June, about four weeks after entering the nymph
state, one of the female specimens threw off its envelope and became perfect, and proved
to be a species of the genus Monodontomerus. A few days afterwards one of the males

appeared; and in the « ; ; |
eds e course of a week, before the 3rd of July, most of my specimens had

OF CERTAIN CHALCIDIDZ AND ICHNEUMONIDZÆ. 69

Of fifteen specimens allowed to complete their changes, there were only two males, with
thirteen females. The remaining specimens I had preserved in their larva and nymph
states for dissection. This small number of males coincides with the small number of
this sex in other bee-parasites; but the deficiency in numbers is fully compensated for by
the activity of the individuals. |

The fewness of the males, and their great activity, lead me to believe that the females are
impregnated, not before, but shortly after they have left the cell, and in the hot sunshine.
Like the Chrysidide, these insects are active only in strong light. Both sexes of my speci-
mens always became dull and motionless when removed from the light; but when exposed
to the sun they immediately resumed their activity. They seem to live but a short period in
the imago state. The males died within a few days, and the females in about a fortnight.

I have proposed for this species the name of nitidus *, from its elegant and glistening
appearance. It may be described as follows: |

MONODONTOMERUS NITIDUS.

Male.—Head and thorax brilliant shagreen, with fine short hairs: head broader than the thorax, face
bluish; labrum emarginated; eyes and ocelli large, dark brown; antennæ 11-jointed, basal joint

` coppery. Prothorax compressed and slightly excavated at the sides. Metathorax and scutellum
large. Abdomen green bronze, hairy, petiolated, very much compressed at its base, and keeled on
the ventral surface; first and second pairs of thighs green; third pair large, copper-coloured; tibiæ
and tarsi fuscous, very hairy. Wings hyaline, hairy, with black costal spot. Length two lines and
a half.

Female (fig. 12).—Head and thorax brilliant shagreen, hairy: head large; face blue, punctured; eyes and
ocelli large, brown; antennæ pubescent, 11-jointed, with the basal joint coppery, as in the male.
Thorax compressed laterally. Scutellum very large. Thighs green, shining. Tibiæ and tarsi hairy,
fuscous, with an acute spine at the articulation of the tibiæ. Abdomen coppery, polished, with a few
white hairs, subsessile, compressed at its sides, and strongly keeled; ovipositor exserted, longer than
the abdomen, and very acute. Wings dusky iridescent, hairy, and with dark marginal spot. Length

of body two lines f.

From the length of the ovipositor in this insect, we may conclude that the female does
not enter the bees' nest to deposit her eggs; but that she perforates the cell and conveys
them into it, after the cell is closed, and probably after the young bee is hatched. Every
part of the anatomy of this insect, as of the preceding, and of every other species when
attentively considered, will thus be found to exemplify its general economy, and to indi-
cate how closely the one is connected with the other, —how intimately associated is ‚the
instinct of a living being with special conformations of its organism. Some other families
of Hymenopterous parasites are marked instances of the unfolding of peculiar instincts
subsequent to the development of particular structures. Amongst these we may notice
two of the true Ichneumonidae, Paniscus virgatus and Ichneumon Atropos.

Postseript to the foregoing Section of this Paper.
| Read May 1, 1849.

I am desirous of appending a few remarks to the section of this paper that has already
been communicated to the Society, before proceeding with the remainder.

These refer to the second bee-parasite described, and provisionally named Monodonto-
merus nitidus. The parasitism of insects of this genus on Anthophora had not previously
been ascertained. JM. obsoletus had been suspected of infesting the genus Osmia*, like
one of its affinities t, but its larva, so far as I am aware, was unknown. I found the
larva of M. nitidus in the nests of Anthophora, on the 27th of September, 1847, and men-
tioned the fact to an entomologist, Mr. F. Smith, who, some time afterwards, as he him-
self informed me, obtained. specimens of it from the same locality. From a note on its
habits, which he has recently communicated to this Society 1, it appears that the larva is
carnivorous, and feeds on the bee-larva, and not on its food, as I had believed. lam
thankful for this correction of observation. The mistake arose in my haste to furnish

part of this paper for reading to the Society by a given time, which obliged me to forego an
examination of the parts of the mouth, which are difficult to observe, and compelled me to
rely on the appearance of the fæces, and on the fact of having found my full-grown speci-
mens in the cell of the bee with the dried-up remains of the bee-larva. I have now made
the required observations on the oral organs, and also have microscopically examined the
contents of the digestive apparatus, and these lead me to agree with Mr. Smith in regarding
the larva as carnivorous, and not as pollinivorous. The mandibles are slender, arched
and acute, and are fitted only for piercing, and not for comminuting food ; the labium and
maxillæ are thick, large and membranous, somewhat like those of the larva of Paniscus.
The contents of the digestive apparatus I found to consist of large and small nucleated
celis, consolidated together, and darkened in appearance, conditions induced probably by
admixture with secretions from the parietes of the apparatus during digestion.

Thus further examination of this larva tends but to confirm, instead of to confute the
general view which I have constantly maintained,—that structure, when carefully and
accurately investigated, is an infallible index to function and habit. My incorrectness in

PANISCUS VIRGATUS, Foure.

The parasites of the genus Paniscus, and their affinities Ophion, which are some of the
most active and percipient of insects in their perfect state, are examples of one of the
very lowest forms of life as larvee, as well as of one of the most curious modes of nutrition.
In the earlier stages of growth they more resemble cotyledonous vegetables, in general
appearance, than animal organisms which are destined to become some of the most perfect,
' and most active of their Class. I have traced Paniscus virgatus from the bursting of its
egg to its assumption of the imago state, and have watched its growth and the formation
of its tissues.

The earliest notice I am acquainted with on the habits of an insect of this family is
of Ophion luteum, by Goedart*, who found five specimens of the imago produced on
the 29th of June from the hard cocoon formed in September of the previous year, by
the larva of Cerura vinula, L. Bonnet afterwards, as quoted by DeGeer }, made some
observations on the singular economy of this insect. He remarked that the eggs of Ophion
are attached to the outside of the body of the caterpillar of the Puss-moth, by a short
pedicle or footstalk inserted into the skin, and that the parasite when hatched is nourished
on the outside of the body, still attached to its shell and pedicle like a vegetable growth.
DeGeer $ found the same insect on the Puss-moth larva, and ascertained that several indi-
viduals subsist on the same caterpillar, which dies of exhaustion after it has formed its
hard wooden cocoon. More recently the eggs of this genus have been the subjects of a
memoir by Dr. Hartig, as mentioned by Mr. Westwood ||, but this memoir I have not yet
seen. I do not pretend, therefore, to claim entire originality for the few observations which
I have made on Paniscus, but merely to state what I have myself observed, in accordance
with the views I have proposed.

On the 26th of September, 1847, I found many nearly full-grown larv of the Broom-
moth, Mamestra pisi (fig. 13), feeding on that plant in the hot sunshine. On the following
day I detected a number of little shining black-looking bodies (v) on one of these larvze,
attached to different parts of its three thoracic segments. On examining these bodies more
closely, I found to my surprise that they were black shining eggs (a), inserted at one end
into the skin of the caterpillar. These eggs were somewhat oval, or rather pear-shaped,
the attenuated footstalk being lodged under the skin. There were eight thus attached.
But what fixed my attention closely was, that most of the eggs had already burst, or were
in the act of bursting longitudinally (14 c), precisely as I have formerly seen and described
in the eggs of the Zuide. Each egg had divided in the middle line, at its anterior ex-
tremity, and the two halves of the shell were separating like the cotyledons of the seeds of

leguminous plants, whilst the head of the little white larva was slowly passing out between
them (14 a & b), like the germ-roots, to become affixed by its mouth to the skin of the cater-
pillar, the body being retained within the shell. As the parasites became attached, the fated
caterpillar moved about with increased rapidity, twisting and turning its body in every direc-
tion, and evidently endeavouring to get rid of its new-born enemies, but to no effect. The
little beings, securely affixed by their shells, giving no evidence of sensation, and scarcely
even of vitality, were unaffected by these endeavours to displace them, and retained firm
‘hold. The cleavage of the shell was chiefly on the under surface, so that the two halves
formed a kind of bivalve covering or cloak to the larva, and clasped its body as the head
emerged. The head at first was the only portion of the larva that was exposed. But
the little creature grew rapidly, deriving its nourishment by slight puncture and suction
through the skin of the caterpillar, with scarce an abrasion of the surface. The rapidity `
of its growth in this way was truly astonishing, the whole of the nutriment thus imbibed
being appropriated to its increase, excepting only the very little expended by cutaneous |
transpiration; for respiration at this early period can scarcely be proved to have com-
menced, as I was unable at this stage to detect the respiratory organs, while the digestive
cavity, as we have already seen in other parasites, was imperforate. Within £wo hours
from the bursting of the shell there was a marked increase of size in the larva. In the
course of the first day the prothorax and the head were extended from the shell, and early
in the second day the three thoracic segments, as well as a large portion of its ventral sur-
face, were exposed, the larva (fig. 15) then being nearly twice its original size in the ovum.
When examined by a lens it seemed to be almost entirely formed of an immense stomach,
connected with the mouth by a short and very narrow cesophagus, as in the larva of Mono-
dontomerus. The motions of the stomach, vermicular and incessant, were distinctly seen
through the tegument. As the insect increased in size, it was more and more extended
from the shell. Its anterior part grew the most rapidly, the largest segment being the
first, or prothoracic.

It was not until after the completion of the second day that I was able to detect the
respiratory organs through the tegument, although I had previously sought for them with
much care. The little vegetating being then seemed like an embryo, which,— instead of
deriving its means of growth, like other embryos of its class, in the unburst egg by imbi-
bition of fluid from without, through its shell and membranes,—had been prematurely
exposed by the sudden rupture of its envelope, and left to perish, or to absorb adventitious
nourishment from other bodies. I could not help regarding it among insects as the
representative of the embryo Kangaroo among quadrupeds, prematurely liberated from its
foetal coverings, and extruded from the body of its parent, to continue existence attached
externally to the teat in the marsupium. But still more closely did it resemble the em-

| bryo of the inferior Myriapoda,—the Iulide, in which the young, after bursting its shell
longitudinally, as in Paniscus, is detained within it, and continues to grow by imbibition
of nourishment through its membranes from the surrounding medium. There is, how-
ever, this difference. In the Zwlide the retained embryo is inclosed in its membranes
piis NE and does not throw them off until it has acquired organs of loco-
is. o move about and seek food. But the young Paniscus bursts its

OF CERTAIN CHALCIDIDZ AND ICHNEUMONIDE. 73

membranes with its shell, although it is completely apodal and incapable of locomotion,
and has to derive nourishment, not by simple endosmosis through its foetal envelopes into
the tissues of its body by similar means, but by the direct abstraction of fluid from another
living body into its own. To ensure this, the larva requires to be attached by its terminal
segments to its shell during the whole period of its growth, and like the larvæ already
described, it passes no fæces until it has attained its full growth, and becomes detached
from its shell, to prepare for its change to a nymph.

After the second day I was accidentally prevented for some time from making any very
precise observations on these insects, further than noticing that they grew rapidly from
day to day, and that they retained their connexion with the shell.

On the 4th of October, the ninth day of their existence, I was enabled to resume my
examinations of them, and then found that several of them had perished, and that three
only remained healthy and thriving. The caterpillar on which they had fed had become
shrunken and wasted, but still retained sufficient irritability and muscular power to
contract its body with a quick lateral motion when touched. . The larvæ that remained
healthy were now at least twelve times their original size (fig. 16). The head (16 a) of
the larva, which at first was the most ample region of its body, was now the smallest,
relatively to other parts which had increased. more rapidly, and. but little exceeded the
size of the ovum. The parasites were attached, one on the dorsal surface and one on each
‘side of the caterpillar, the latter one coiling round the inferior surface of the thoracic seg-
ments (fig.17). Their bodies, enlarged and fattened, were of a dark pea-green colour, and
were formed each of fourteen segments, all of which, more especially the anterior ones,
were distinctly marked. The stomach in each was in a state of incessant to and fro ver-
micular motion, and had become enveloped in a thick tissue of little white follicles, which
have been regarded as the rudiments of fat-vesieles. No anal outlet had yet been formed,

nor was there, so far as I could discover, any perforated intestine. In the interval of

i hich I had been prevented from following up my observations, each
nz i T believe, is the first time that the soft-

larva had three times cast its tegument. This, |

bodied Hymenopterous larvæ have been noticed to undergo this change. These larvæ,
therefore, as I have already pointed out, are not exceptions, as they have been suspected
to be, to the general rule of development in hexapods, in so far as refers to the casting of
the skin; although, as the body is still connected with the egg-shell, the ^l ee
are not entirely got rid of until the larva is detached to become a nymph. Ihe skin 1s
fissured in Paniscus, as in other larvæ, along the dorsal surface of the anterior thoracic
segments, and is gradually removed from the dorsal, lateral, and inferior — of 4
head and succeeding segments, by the growth and expansion of the er =~

rounded the twelfth and thirteenth segments: and the third (c), the deciduation of which
I had the good fortune to witness, while examining the larva for other purposes, was in-
ternal to, and partly covered by, the second, and was not forced back further on the
ventral surface than to the ninth segment, although, like the preceding, it was entirely
removed from the dorsal surface. The whole thus formed a,kind of treble sheathing to
the posterior segments of the body, until the period when the larva, full-grown to reple-
tion, was to prepare for its transformation, become detached from its shell, and leave its
deciduated coverings in connexion with it. On the tenth day, October 5th, the larvæ
had further increased in size, were more raised from the body of the caterpillar, and lay
coiled up in a more circular form. Each one was still attached to its egg-shell, although
now more than twenty times its size, and each adhered to the caterpillar by its oral
organs, exhausting and impoverishing it of its juices. The skin of the parasite again
appeared tense and dull, as when about to be cast. The head and thorax had a whiter
and more fibrous appearance, the stomach was less easily distinguished through the tegu-
ment from other viscera, excepting at intervals, and the heart was seen in motion along
the dorsal surface, but with little regularity in its contractions. Its movements appeared
to be greatly influenced by the motions of the digestive apparatus, which seemed to induce
the tissues around it to contract, and thus excite a reflected action in the circulatory organ,
the movements of which appeared to be greatest in the middle of its chambers. The tissue
which has hitherto usually been regarded as the adipose—and which I may hereafter have
occasion to notice more particularly—was now much extended and augmented in size, and
the respiratory organs, although extremely simple, were become well marked. On the
eleventh day the larva was still larger, and became detached from the egg-shell; but
whether this resulted from accident, or from the completion of its growth, I was not then
able to determine. Its tegument had become more opake, and there were tubercular pro-
jections at the sides of its abdominal segments, immediately below the line of longitudinal
tracheal vessels. On the twelfth day I found that the separation of the specimen from its
shell was accidental and premature, and that the larva was unable to re-affix its oral
organs to the skin of the caterpillar and perished. This is usually the case when a larva
is prematurely detached; and this result explains the necessity for the continuance of its —
connexion with the egg-shell, which, as DeGeer has observed of the eggs of Ophion, is so
firmly inserted into the caterpillar that it cannot be removed without lacerating the skin.

already indicated this as the general form of body of the larva of this tribe of parasites,

and has mentioned that they have lateral fleshy tubercles. He has described the parts of

de mouth as consisting of “two obliquely deflexed horny mandibles, very small, slender,

and acute, beneath which is a curved fleshy lobe, formed by the union of the dilated
maxillæ and labium." In this account he is perfectly correct. But while challenging
the description given by Reaumur of the head of the larva, he appears himself to have
fallen into the singular error of mistaking the rudiments of the future antennæ for ocelli.
He says *, “The head is furnished with two distinct round points—resembling ocelli,"
but he makes no allusion to the existence of antenne. No organs of vision exist in any
of the parasitic Hymenoptera at the “points” he has indicated in his text and figure of
the head of these larvæ, the parts referred to being the apices of the antennæ of the future
imago. I have traced the antennal nerves into these parts in the larva ef Ichneumon
atropos, which closely resembles in this respect that of Paniscus. The small size and
deflection of the mandibles partly account for the difficulty which this larva has in re-
attaching itself to the caterpillar when detached from its shell, and the consequent neces-
sity for this attachment for its preservation, —premature removal resulting in starvation,
as with my first specimen. My second specimen, which left the shell only when matured,
T placed on some light mould, in a covered glass vessel, to observe its changes. I ex-
pected to have seen it bury itself in the earth, knowing this to be the habit of the larva on
which it feeds; but in this I was disappointed. Its instincts were more limited and im-
perfect than I had imagined. On the day after placing it on the mould, it was lying ina
slight hollow on the surface, made by contracting and turning its body, and was in the
act of spinning a delicate web of silk, under which it was lying, and where I hoped to
have seen it change to a nymph. It attached a few grains of earth to the inside of the
web, and between the threads scattered here and there, like the particles of earth inter-
woven with its threads by the caterpillar of Mamestra, but after remaining at rest for a
couple of days, I found it discoloured and dead.

Thus checked in my observations, I had no hope of being able to complete this inquiry
by tracing the insect to its imago state, until, on the 6th of April, 1848, I found, on exa-
mining the earth in a breeding cage, in which I had kept many larvæ of Mamestra pisi,
to obtain the pupæ of that insect, —in several earthen cocoons formed by the caterpillar,
from two to three cylindrical leather-like cases of a black colour, applied so closely
together that their walls formed angular surfaces, precisely like the cells of a honeycomb,
There were from two to three of these cylindrical cases in each earthen
cocoon of Mamestra. Each cylinder measured about six-tenths of an inch in length. In

some cocoons there were three cylinders, and in one only I found four. In the latter

instance they were smaller than when the cocoon contained but two, as if the inmates

"had not been sufficiently fed. This was markedly the case with two of the four speci-
mens found together, which were scarcely more than one-half the size and length of the
others. Each of the cocoons of Mamestra was completed in the usual mode of this larva,
its earthen walls being smoothed on their interior, agglutinated together, and lined with
silk; and each contained, besides the cylinders of the parasitic insects, the dried-up remains
of the caterpillar. Saa

From these facts it seems to follow, that the economy of the parasite is this: the parent
Ichneumon-fly deposits her eggs on the caterpillar when this is nearly full-grown, and

will soon enter the earth, which it does, as I presume must have been the case with these
insects, while the parasites are very young and small, otherwise they may be injured or
detached while the caterpillar is burrowing and making its cell. The fated insect, ex-
hausted by the parasites, has but sufficient strength to complete and tapestry its earthen
chamber before it dies, leaving its newly-formed abode to the occupation of its enemies,
which grow rapidly, as we have seen, pass through the changes I have traced, and then
form their own cocoon in which they are metamorphosed to nymphs.

On examining one or two of the cylinders at the time of obtaining them in the begin-
ning of April, I found that the inmates had very recently changed to nymphs (fig. 18).

On the 8th of May one of these assumed the imago state (fig. 19), but escaped on my
incautiously opening the box that inclosed them. On the 14th two more appeared, and I |
now had the means of identifying the species. It proved to be as I have stated, Paniseus
virgatus.

It is probable that these insects may have come forth at a period earlier than in their
natural haunts, having been kept in a warm room, and the temperature of the season, at
the time of their evolution, being considerably higher than usual. It is worthy of remark,
however, that the moth, or the larva of which this Paniseus is a parasite, kept during its
pupa state under precisely similar cireumstances, had already made its appearance a week
at least previously; so that, under similar conditions of locality and temperature, the
parasites came forth at the latest period.

IX. Further Observations on the Genus Anthophorabia.
By GEORGE NEWPORT, Esq., F.R.S., F.L.S. $c.

Read February 3, 1852.

HAVING had the good fortune, in September last, to re-discover in the nests of Antho-
phora, at Gravesend, the Chalcididous parasite Anthophorabia, which, twenty years ago,
I found at Richborough in Kent—and an account of which is given in my paper on the
Chaleidide and Ichnewmonide—I feel it necessary to offer a few additional observations on
this insect ; since one of the most remarkable peculiarities of its male sex—and on account
of which the genus was characterized and named in that paper—has been denied to be a
fact—the denial being printed in the “ Proceedings” of the Linnean Society*, and else-
wheret. 'The peculiarity to which I allude is the possession of a single stemmatous eye,
in the.place of a compound eye, at the sides of the head in the male.

At the time of communicating my paper on the Chalcidide, &e., to this Society, I was
nof in possession, as was then pretty well known, of specimens of the insect itself, but
only of delineations which I had made in the year 1831 from living specimens, and at
which time, and for two or three years afterwards, I found the insect in such abundance
that, expecting to be able to obtain it at pleasure, I neglected to preserve it. "Through
the long interval of time which has since elapsed, up to September last, I have not
again been able to find it. It was upon the very fact of the existence of stemmatous
eyes, in the place of compound ones, in this insect, that some important physiological
deductions in my paper are founded; and thence it was reasonable to expect that every
inquirer would have believed that of this fact, at least, I must have been quite certain,
before venturing to deduce conclusions. Yet this has been repeatedly questioned by Mr.
Westwood, and even in the ** Proceedings” of the Society itself}.

As I am now in possession of specimens of the insect, which I beg to lay before the
Society$, I am enabled to prove that not only do stemmatous eyes, instead of compound
ones, exist in the male, as I have stated, but also that the principal characters given in
my paper as marking the genus,—the enlargement and exeavation of the basilar joint of
the antenna, as well as the enlargement of the middle joint, —are correct. The male has a
single stemmatous eye on each side of the head, and three stemmata on the vertex, so

t “ The asserted possession of stemmatous eyes by the male was regarded as erroneous, there being no instance of
such a structure, throughout the whole range of winged insects, whilst it is essentially a character of some of the wing-
less tribes."— Westwood in Proceedings of the Linnean Society, vol. ii. p. 37.

that, with the insect before us, we are now enabled to demonstrate that this little creature
really does possess the eyes stated*. It is but just, however, to mention, that with regard
to some other details of less importance, my former description admits of revision ; but
any occasion for this, although asserted, could only have been. guessed at as vaguely as
with regard to the eyes, by those who have never seen my insect. Thus I now find that
the club of the antenna, in both sexes, is formed of a plurality of closely-united immovable
segments, instead of being but a single joint; a circumstance which affects the declared
number of parts of which the antenna is composed ; and the possibility of which I have
elsewhere admitted. Further, the number of joints in the tarsi may either be regarded
as five, as I have described them, if, as anatomists, we consider as a distinct joint the pad-
like terminal portion of the foot ; or as four only, if this part be discarded, and the number
be computed in the way usual with entomologists. .

With regard to the supposed identity } of Anthophorabia with the insect mentioned in my

paper of the 20th March, 1849, p. 64, on the Chalcidide, and which had been named Me-
littobia, but which, up to that period, had not been described §, there cannot be much diffi-
culty in arriving at a conclusion in the negative; if the description in the accounts given by
the entomologist who has since repeatedly characterized the latter insect be correct. Thus
the male of Anthophorabia has stemmatous eyes, while that of Melittobia is described as
having-* eyes and stemmata wanting ||,” or as ** omnino cecus§,” or “ ceecus**.” And
again, the male of Anthophorabia has the middle joint of the antennæ “ large and globose”
or subangulated,: while that of Melittobia was first stated to have ** 2nd and 3rd joints
small,.nearly equal, 4th, 5th and 6th very small and subannulosett," and afterwards these
characters were revised by the omission of all reference to the second and third joints, the
statement being simply “ articulis 4to, 5to et 6to minimis}}.” So that, presuming these
several descriptions to express the fact, the question must be looked upon as decided.
- Thus much then with regard to the identity of the genus Anthophorabia. In respect
of the species there appears to be even less difficulty, Anthophorabia retusa being described
both generically and specifically in my former paper, while no specific characters whatever
have even as yet been published of Melittobia Audouinii. |

I now propose to revise the generic description of Anthophorabia in the following
manner :— :

As the specimens which I now possess afford some specific characters which I do not

do not possess any of those to compare with them, I propose to name the species I have
obtained at Gravesend, provisionally, in the event of its proving to be distinct, Anthopho-
rabia fasciata, and to describe it as follows :—

These insects were found while myself and a friend were searching for the larve of
Monodontomerus nitidus, on the 14th of September, 1851, at Gravesend; and although
met with in only one bee's nest, L was fortunate in securing nearly one hundred and fifty
specimens. Most of these were still in the nymph or pupa state, but some of them had
already become imagos. On examining them on the following day, I found that several
more had recently changed ; and while I was engaged in watching them, I had the satis-
faction to observe two males throw off their coverings. Having placed the whole in a
shallow vessel covered with glass, I was enabled to watch their proceedings. These males
began immediately to traverse round the interior of the vessel leisurely, but very assi-
duously, touching and turning many of the yet undeveloped female nymphs with their
antennæ. Occasionally they raised their rudimentary wings, but made no attempt to fly,
or even to leap, as the females frequently do, although they were in no way confined for
room. In this manner they continued to roam about, without making the slightest effort
to escape, their sole attention being evidently directed to the unhatched females.

The males appear to be very few in number in proportion to the females, as out of the
hundred and fifty specimens obtained I could only find eleven. They are also very short-
lived, as the whole of those which came forth in the afternoon of the day subsequent to
that on which they were found, were dead on the following morning. The females were
much longer-lived, and not only crept about freely, but occasionally leaped to a consider-
paren to observe any direct communication between the sexes, notwithstanding
the apparent attentions of the males in the way I have mentioned. Yet there afterwards

appeared reason to believe that some of the females had been fecundated, probably, as for-

' merly suggested, while they were still included in the closed bee's nest. I had placed
nearly a hundred females, including some which had been hatched in the closed cells, and
others which I afterwards saw change from the nymph, in a glass tube, secured, as I be-
. lieved, completely with a cork. For a few days the insects remained quiet, occasionally
voiding faeces; thus showing that the females, at least, are destined to take food, and sur-
vive for some time. But at the end of ten days or a fortnight I found, to my surprise,
that the glass tube had become nearly empty, almost the whole of the insects I had
inclosed in it having escaped, although the cork had not once been removed during the
interval. They had contrived to insinuate themselves into slight depressions in the sides
of the cork, between it and the glass, as I found one or two thus in the act of escaping ;
while others, which had obtained their liberty, were noticed in different parts of the room,
one or two being found in the window and elsewhere. This fact, trifling as it is, is inter-
esting, as probably illustrative of the penetrating, fossorial habits of the species, and,
with other circumstances, leads me to believe that the insect penetrates into the closed
cell of the bee to deposit her eggs on the nearly full-grown larva within.

Happening about the 20th of November, seven or eight weeks after this observation, to
examine a box in which I had placed some larvæ of Anthophore in partially opened cells,
I noticed a small parasite attached to the surface of one of them, and which, from its size,
I at first mistook for a larva of Monodontomerus. But on opening the box again, about a
week afterwards, I remarked that the parasite had but slightly increased in dimensions ;
while, on closer examination, I found within the cell, beside the bee-larva, three perfect
female Anthophorabie ; and on watching these for a few minutes, two of them seemed to
be engaged in oviposition. I then saw that instead of there being only one or two para-
sitic larvee attached to the skin of the young Anthophora, there were many, in very different
stages of growth; from that which I had first observed, and which had nearly attained its
full size, to others which did not exceed the fifth of a line in length. I now concluded
that these were not the larvæ of Monodontomerus, as I first supposed, but of Anthopho-
rabia, an opinion which was confirmed by subsequent examination with the microscope ;
and this further induced me to think that the females noticed were, as they appeared to
be, depositing ova. I did not observe any of these larvee parasites on the young Antho-
phore at the time of procuring them from their natural haunts in September, when the
cells were first broken and their inmates exposed, at which time they appeared to be quite
healthy. Nevertheless, one or two of the parasites now upon them were nearly full-grown,
and measured nearly a line in length, while others were so small as to be hardly recog-
thus giving further reason to suppose that the eggs had been deposited and

ed at different periods. The way in which this appeared to be capable of explana-
tion was, that some of the female Anthophorabie which had escaped from the glass tube,
s em — ee lagen " — which lay exposed in their cells
themselves into the box, had at differ i ü gt je M ABEL: inna

MR. NEWPORT’S OBSERVATIONS ON THE GENUS ANTHOPHORABIA. 83

From the circumstance that each parasite was attached to the surface of the bee, and
fed upon it from without, like the larva of Monodontomerus, it was evident that the female
does not insinuate her eggs into the body of the bee, but merely attaches them to its skin ;
while from the circumstance of nearly the whole of the females I had confined in the tube
having escaped by insinuating themselves between the sides of the cork and the glass, and
forcing their way through chinks which appeared much too small to admit of their passage,
there seems reason to think that the usual habit of this species may be to penetrate into
the cell of Anthophora after it has been closed, and deposit her eggs on the nearly full-
grown inmate. This supposition is further countenanced by the acute and denticulated
form of the mandibles of the female, and by the absence of an exserted ovipositor, which
structure would perhaps be necessary under other circumstances. Further, also, that the
bee is infested not by a few, but by an abundance,—a whole brood of these creatures,—
which entirely destroy it.

I have allowed my bee-larva, with its parasites, to remain in a cold room up to the
present time, but the latter have scarcely at all increased in size, and yet they remain

firmly attached to their victim, appearing scarcely even to vegetate.
_ This is precisely the condition in which the bee itself remains during winter; both that
and its parasites requiring a high temperature of the sand-bank, heated by the sun’s rays,

for their evolution.

ICHNEUMON ATROPOs, Curtis.

SEVERAL years ago, chiefly in the year 1829, I obtained many specimens of Ichneumon
Atropos (fig. 1. Tas. IX.), both in the larva and perfect states, in the neighbourhood of
Canterbury, but I have not yet met with it in any other locality, nor since the year 1834*.
Mr. Curtis, to whom we are indebted for the description, and an admirable figure of the
species t, states it to have been bred by Miss Giraud at Faversham, from the larva of Ache-
rontia Atropos; that the perfect insect, from which his drawing was made, was taken at
Rochester by Professor Henslow; and that another specimen had been taken at Darent
Wood by Mr. Davis, so that the insect appears to be a truly Kentish species. It was by
no means uncommon in the neighbourhood of young ash plantations, at Canterbury, in
the month of July, at the period I have referred to, when I took it on the wing; and I
have several times reared it from the pupa of Sphinx ligustri, and very frequently have
found the larva within the body of the larva of this Sphinx. It seems in fact to be
a parasite common to this Sphinx; much more so perhaps than to Acherontia Atropos.
Mr. Curtis, when describing the species, suggests that the true Ichneumons “ prefer
naked caterpillars, and probably puncture them after they have descended into the earth,
but before they have changed into chrysalids." But this is not the habit of Ichneumon
Atropos, as I have often found the Ichneumon-larva (fig. 2 a, b, c) within the body of the
Sphinx caterpillar several days before this had acquired its full growth, or had ceased to
feed, and consequently long before it would have entered the earth to change to a pupa.
I suspect that the egg of the Ichneumon is deposited quickly after the caterpillar has
changed its skin, and has entered its last period of growth; since, at about the middle of
that period, I have found the parasite within it more than a quarter of an inch in length ;
and consequently, it must then be at least two or three days old. This length of time,
added to a similar period, which we may suppose to be necessary for the hatching of the
ege after deposition, will bring us to the commencement of the last stage of the caterpillar,
when its tegument is soft and pierced with least difficulty. I am not aware whether the
Ichneumon-egg is deposited on the surface of the skin through which the larva eats its
way into the body, when hatched, like the larva of Séylops, or whether, as seems to be most
probable, the egg is plunged at once into the caterpillar. The latter opinion seems to be

* Since this paper was read, I have obtained two specimens of the imago from pupæ of Sphinx ligustri during the
past summer, 1852.

supported by the fact that I have never yet met with even the youngest larvæ between the
skin and muscles of the caterpillar, but always internal to the muscles, imbedded in the
so-called fatty tissue, between them and the alimentary canal, and always on the dorsal
surface, and usually with its head in the direction of that of the caterpillar. I have found
it in different stages of growth, from one-fourth to three-eighths of an inch in length (a),
as early as the middle of August, when it is of a light pea-green colour; but I have obtained
full-grown specimens (c, d) only from the pupa of the Sphinx, sometimes as early as the
end of October, but more frequently not until the commencement of March, and sometimes
as late as the end of April. Usually, one egg only is deposited in each caterpillar, but
sometimes there are two, and both become hatched, although of the parasites one only
arrives at maturity, as one is invariably destroyed by the other. I have the following
entry of a fact of this kind in my note-book with the date “ March 13, 1832," which shows
that two larvee may exist in the pupa of the Sphinx up to a late period, but that one is
then destroyed. ‘The pupa now examined was one in which Ichneumon Atropos had
deposited two eggs. Two larvæ had been hatched, and these were located in the lower
part of the abdomen of the pupa. One of them was very small, being scarcely more than
one-fourth of an inch in length, and appeared to have been dead for some time. The
other was a fat well-fed specimen, about three-quarters of an inch in length and one-sixth
in diameter. It seemed to have destroyed part of the fatty sacculi of the Sphinx, and
was lying in the cavity of the body, but it had not injured the upper part of the digestive
apparatus, the stomach, behind which it lay so imbedded that I had almost mistaken it at
first for the intestine and colon, which had not undergone their proper change. The
nervous system of the pupa had not been injured by the larvæ, although its changes had
been retarded. It thus appears that the Ichneumon sometimes deposits more than one
egg in the body of the caterpillar, as several times before this I have found two of these
larvee in the same insect, although, I believe, never more than one of them comes to
perfection." All my subsequent observations have confirmed this conclusion.

The usual situation of the parasite in the Sphinx-pupa is in the tissue of the middle
part of the body beneath the dorsal vessel and above the stomach, on which it often rests.
This is the position of the full-fed larva in the drawing and preparation (fig. 3), and this
ia the specimen alluded to and partly described in my second memoir on Meloë, printed
in the Society’s Transactions, vol. xx. p. 385. It was obtained at almost the latest period
of the larva state, on the 18th of April, 1832. The other specimens exhibited were pro-
cured between that period and the month of October, so that the insect continues to sub-
„Sist on the Sphinx, and probably passes into a state of hybernation with it, during the
long interval of six months. One specimen found on the 20th of March, and removed

posterior in the abdomen of the pupa. I put it by for future examination in a vessel of
water, having first made a drawing of it (fig. 2d). The spiracles, on each side of its body,
are oval, corneous, and slightly project from the tegument, and are situated one at the
anterior part of each segment, a little above the longitudinal trachea, and immediately
anterior to the trachea that supplies the dorsal surface of each segment. The whole of
the tracheal vessels are distinet and distended with air. On looking at it this morning I
found it dead.” So that although the parasite may reside for many months bathed by
the fluids of the Sphinx, it perishes when a change occurs in the degree of activity of its
respiratory functions. The length of time which it remains in the nymph-state is about
a month or six weeks at the utmost, as most of the specimens I have bred from the pupa
have appeared in June. The perfect insect makes its way out of the dead pupa of the
Sphinx by perforating the case with its mandibles, on the dorsal surface, and sometimes,
as in the preparation now exhibited, it becomes fixed in the orifice and unable to escape
(fig. 4).

The body of the larva (fig. 2 a to d) is composed of fourteen segments, or, if the pedal
process of the last segment be reckoned, of fifteen. It is elongated, somewhat tapering,
and curved in its earlier stages of growth; but is thick, fat, and pointed at its anal
extremity, when mature. The pedal or terminal portion of the last segment is pointed and
projecting, and is opposable to a process from the inferior margin of the thirteenth seg-
ment, with which it forms a kind of forceps, or prehensile organ by which the larva may
affix itself, and change its position in the body of the Sphinx The lateral margins of all
the segments are thinned and project as tubercles. These are well-marked in the pro-,
meso-, and metathoracic and pre-abdominal segments, but are most distinctly tubercular
from the fifth to the eleventh inclusive. These latter segments have also distinct tubercles
or segmental appendages on each side of the ventral surface in the shape of mammæ, and
in the position of the false feet of the Terebrantiate Hymenoptera to which they may be
regarded as analogous, and as subservient to the movements of the larva within the Sphinx.
The lateral tubercles of the Ichneumon-larva have already been noticed by naturalists, but
I believe this is the first time that ventral tubercles also have been discovered. In the
very young larva they are situated nearer to the side of the body than in the full-grown,
and become more and more approximated to the median line, as the growth of the larva
proceeds, by the greater extent of growth and development of the dorsal than of the ventral
portion of the segments; thus beautifully illustrating the corresponding process of growth
of the segments, and the approximation of the limbs to the median line of the body, in the
Myriapoda. But although pedal tubercles exist along the ventral surface of the abdominal
segments, the future true legs of the perfect insect are indicated only by six white points
on the ventral surface of the thoracic segments, in the precise situation, however, of the
tubercles on the abdominal.

The head (fig. 5) and mandibles (d) of the larva are strong, corneous and of a yellow
colour, with the margins and apices of the mandibles black, curved and sharp-pointed,
fitted only for piercing and suction, and not for manducation. The maxillæ (e) are three-
jointed, with the terminal joint broad, triangular, soft and membranous, the second joint
very short, and the basal joint strong and elongated. The labium (f) is triangular, with a

slight median ridge, and a narrow membranous border, admirably fitted with the margins
of the maxillæ for suction. The strength of the mandibles, and the consolidation of the
parietes of the entire head, prove to us that the force necessary to overcome the contractile
power of the tissues in the Sphinx, in obtaining nourishment, is by no means inconsider-
able; yet this force appears to be little, if at all, under the power of volition, since the |
Ichneumon-larva, like that of Paniscus, exhibits only the very slightest indications of
sensation, when touched or pressed. It makes no distinct effort to escape, but merely
contracts its body, perhaps simply by reflected action, without any intervention of con-
sciousness. This is precisely the condition, as regards the consensual functions of its
nervous system, (fig. 9.) under which we might have expected it to exist. Shut up in
the body of another animal, and subjected to the compression of its tissues, the endow-
ment of sensation would only entail on it an amount of suffering proportioned to the
degree of its perception. Vegetative, or simple organic life, therefore, is, as yet, sufficient
for all the requirements of its existence; although afterwards it is to become endowed, as
certain of its consensual organs are developed, with perceptions and instincts the most
acute. Thus we find in this larva that organs of vision, totally useless to it in its intra-
abdominal abode, do not yet exist; and the place of their future development is scarcely
even indicated; while the antennæ, almost equally useless to it in its present condition,
exist only in the most rudimentary state, merely as slight horny elevations, on the front
of the head, (fig. 5 a) on each side of the clypeus (6), formed of a series of concentric rings
(fig. 6) the centre of which is the apex of the future tactile organ. Into this centre I
have succeeded in tracing the termination of the antennal nerve; the optic nerves, for the
future eyes, being in their usual situation at the sides of the cerebral ganglia. I have
also succeeded in tracing this nerve into the corresponding part in the larva of Anthophora,
in which the antenna is more developed than in Ichneumon, and forms a little cone of
concentric rings. In Monodontomerus the same part is terminated by a single hair (fig. 7),
precisely as hairs and spines originate in the central nuclei of tegumentary cells in the —

larva of Meloé. — 3
I have elsewhere shown* that the form of the digestive apparatus is very similar, at the
earliest periods of growth, in all parasitic Hymenoptera, whether they are enclosed in the
same cell with their victim, as in Monodontomerus, whether carried about with it attached
to its surface like Paniscus, or whether shut up within its body like Ichnewmon. In each
of these instances there is not merely a general similarity in the form of its parts, but
there is also a concordance in their function. The intestinal portions continue small and
imperfect, and no fæces are passed until the larva has arrived at its maturity. I may now
further state that this principle, or law, is not confined to the strictly parasitic, or carni-
vorous larvee, but operates, as I believe, among the omnivorous, and certainly among the
true pollinivorous. The digestive apparatus in the larva of Zchneumon (fig. 8), is a pear-

Anthophora, as I ascertained many years ago, the chief portion of the digestive organ is
an elongated stomach, and although in this instance a short intestine and colon exist, not
an atom of fæces is passed, as I have many times, to my complete satisfaction, proved,
until the whole of the food is consumed, and the larva has attained its full size.

IV. DEVELOPMENT OF THE ALIMENTARY CANAL AND ITS APPENDAGES.

These remarks on the anatomy and development of parasitic Hymenoptera, compared
with their economy and instincts, lead us to inquire into the mode in which the alimentary
canal in Insects is formed. The first developed portions of the parietes of the body in the
embryo are the ventral and lateral divisions of the segments. These are produced before
the alimentary canal is commenced, the space between them being occupied by the yolk,
which supplies the means of growth to the whole. The lateral portions of the segments
grow from below upwards, and their free margins gradually more and more approach
each other, until at last they meet along the median line of the dorsal surface of the
body. The parts which first meet are those of the cephalic, and afterwards those of the
anal segments, and the junction of the remaining segments then proceeds in gradual suc-

cession from behind forwards, as I have witnessed in very numerous observations in the
embryo of Forficula. The whole of the remains of the yolk, composed entirely of masses
of nucleated cells, is thus gradually enclosed within the body, by the successive union
along the dorsal surface of the two sides of the segments, from behind forwards, the last
portion included being in the prothorax. The fact of the yolk entering the body at this
point of the thorax in the Crustacea was first pointed out by Rathke. From the remains
of the yolk thus included the alimentary canal is entirely formed, the external portion
giving origin to muscular tissue and basement membrane, and the internal, besides sup-
plying nutriment for the further development of the embryo, becoming organized into an
elaborating tissue, which for a time retains the general character of the original cell-
masses of the yolk, as shown in Monodontomerus. The termination of the future ali-
mentary canal is thus the result of a folding on itself of the first portion of the yolk included
by the completion of the anal and penultimate segments, and is the commencement, poste-
riorly, of the column of cells which, becoming perforated, constitute the future colon and
small intestine, and which retain the cellæform structure to so late a period in some larvæ,
as in the instance we have seen in Monodontomerus. In this way, formed from the
included yolk, the digestive apparatus becomes a hollow cavity, closed, at first, at its
abdominal end by the approximation of the whole of its component structure, but com-
municating anteriorly with a canal which is formed between the parts of the future mouth,
and which becomes its inlet or esophagus, the connexion of the yolk with the dorsal
surface of the body in the prothorax being entirely obliterated. As the growth of the
body proceeds, the walls of the alimentary canal become thinner, lose much of their cellæ-
form condition, and acquire a more organized structure. The column of cells which
connect the great digestive cavity with the anal segment, as in Monodontomerus, are
gradually transformed into muscular tissue, from without inwards, and constitute the
future intestine, or colon and ilium. These parts being chiefly for the transit of the fæces,
and further elaboration of the contents of the stomach, are later developed, but acquire a

90 MR. NEWPORT ON THE ANATOMY AND DEVELOPMENT

more muscular structure than the great digestive cavity, which longer retains its celle-
form condition, its lining cells becoming changed into secreting or glandular structures, of
two kinds; one of which elaborates the juices required for digestion of food, while others
take up the results and diffuse them through the body for the general purposes of
nutrition.

Hence we find that the general form of the great digestive cavity is very similar in all
embryos of a given class, at the earliest periods; and similar in all which pursue a like
habit of life, as in Hymenopterous parasites ; the chief structural differences being in those
parts which become small intestine and colon. Different species, even among the para-
sites, differ slightly in regard to these parts, both as to form and as to period of completion.
In Monodontomerus we have found that the whole of the digestive canal long retains its
cellæform condition, its muscular tissue being completed very late. In Zchneumon (fig. 8),
and Microgaster (fig. 11), which feed within the body of their victims, the intestinal por-
tion (g, h, i) of the digestive apparatus is completed more early, and a canal, paved with
epithelium, is formed in it, but continues almost completely closed, and does not admit
into it a particle of the matter to be rejected until the growth of the parasite is complete.
In Mierogaster the small intestine (g) and colon (h) are ready to convey the feeces more
early than in Ichneumon; and this seems to have some reference to the special require-
ments of this species for a more early rejection of the waste of nutrition. In like manner
the more or less early completion of the appendages of the digestive apparatus in the
advanced growth of the embryo, or of the larva, immediately precedes the unfolding of
some speciality of function or of instinct. I have already shown, in the first part of this
paper, that the earliest completed glandular organs connected with the digestive apparatus
in the larva of Monodontomerus, are the salivary. So we find also in Microgaster (fig. 11),
in which they are not only early, but most extensively developed (d), for the production
of that abundance of silk which is formed by this larva in the construction of its cocoon
quickly after it has issued from the body of the insect it has devoured. In Ichneumon
Atropos also, I have found the salivary organs (d) extensively developed in the larva at
an early period, doubtless for a similar purpose. Dufour was unable to detect these
organis in the perfect Ichneumon, although he correctly believes in their existence. The
Malpighian structures (4), attached to the commencement of the intestinal portion of the
digestive apparatus, and the function of which is still a question with some physiologists,
although usually believed to be that of the liver, are completed, as we might fairly have
anticipated, at a much later period in these parasites than in the vegetable-feeding larvze,
in which the food requires greater elaboration to assimilate it with the animal tissues, than

lopment of cæca over their whole surface, from their opening into the alimentary canal to
their distal terminations, which, in all insects, are cæcal, and do not, in any way, anastomose
with any other structure; as some have erroneously supposed them to do with the so-called
adipose, or splanchnic tissue.

Thus we find that in proportion to the more or less early development of any structure
or organ, the function or instinct associated with that organ is more or less early evolved ;
and that in proportion to the completeness of a tissue, such is the degree or perfection of
each special function or instinct in the animal.

Additional Note.

Read February 15, 1853.

The change of form and condition which the alimentary canal undergoes, after the para-
site has ceased to feed (fig. 8) and is assuming its imago state (fig. 10), is as remarkable as that
which takes place in the vegetable-feeding caterpillar, in changing to the chrysalis of the
future butterfly or moth. The short narrow esophagus (e) becomes considerably elongated,
and instead of terminating, as in the larva, in the third or meso-thoracic segment, it is
extended, in the imago, through the meta-thoracie, into the abdominal region. In the
anterior portion of the abdomen, the fifth, sixth and seventh segments, it is then dilated
into a conical-shaped crop (f), which, by a constriction at its termination, and a reflexion
inwards of its tissues to form the cardiac valve, is separated from the true digestive cavity,
the stomach. This portion of the canal, the chylifie ventricle (f, f), which occupied nearly
the whole interior of the body of the larva, is now restricted to the eighth, ninth and tenth
segments. It is a powerful muscular structure, of a somewhat elongated oval shape, and
the length of which is scarcely more than thrice its diameter. Around its termination are
inserted, externally, the hepatic or Malpighian organs, from twenty to thirty in number
(k), where, internally, by a reflexion of the tissues, is formed a second valve, the pylorus.
The canal then becomes narrowed into what may be regarded as duodenum and ilium, or
small intestine (g). Beyond this it is again dilated into a more muscular structure (A, i),
the colon or rectum, which is usually filled with ejecta, and terminates at the anal valve.

The canal in the imago, as in the larva, is formed of distinct layers or tissues, a muscular,
a glandular, and a mucous; and is invested, externally, by a distinct, transparent, perito-
neal membrane, which appears to be homologous with the peritoneal covering of the
viscera in the Vertebrata, and processes, or reflexions of which, in these Invertebrata, clothe
every internal organ, the salivary and hepatic glands, the organs of circulation and repro-
duction, and the adipose tissue, and tracheæ; as expressly mentioned, in regard to the
latter, in my article * INsEcTA*.' bab

The tissues of the alimentary canal are, however, much changed in condition in the
imago, from that in which they exist in the larva,—a change which is accompanied by
some alteration of function in the entire organ. In the larva, in which the canal is little
more than a capacious bag, the external or muscular tissue is imperfect, and consists of

* Cyclopedia of Anatomy and Physiology, vol. ii. part 18, p. 965 (Oct. 1839).

92 = MR. NEWPORT ON THE ANATOMY AND DEVELOPMENT

only a very few longitudinal and transverse fibres, which are separated by wide inter-
spaces (fig. 12 a); the one extending throughout the whole length of the organ, and the
other encircling every part of it; and these are crossed obliquely by a few fibres which
attach the canals loosely to the tegument, and aid its peristaltic movements. But the
glandular or middle tissue is more complete. It is composed of the cells before alluded
to*, which are large, hexagonal in shape, and, in most instances, correspond to the inter-
spaces formed by the decussation of the muscular fibres (b). Each cell in its interior has
a very large granular nucleus. The mucous, or lining tissue of the canal, is formed by a
layer of somewhat flattened cells, which have small granulated nuclei, are loosely aggre-
gated together, and have all the characters of epithelial cells (c). In the imago, however,
the muscular tissue is composed of very strong longitudinal and transverse bands, crossed
as in the larva by a few delicate oblique ones; while the glandular tissue is less marked,
the mucous tissue being most developed; thus, preceding in its changed condition, the
change of food of the perfect insect. |

Every part of the canal is supplied with tracheæ, the trunks of which, one in each

segment, passing transversely inwards, divide into branches, which, again subdivided,
penetrate into and ramify through the structure. These, like all other tracheæ, are formed,
as described by Sprengel, of three tissues, an external membranous, and an internal
mucous, which enclose between them a strong spiral fibre. The external, as I formerly
showed, so loosely invests the middle, or spiral, that, usually, there is some interspace
between them; and, as also mentioned}, this external tissue is simply a reflexion and
extension of the common peritoneal membrane. The ramifications of tracheæ which
penetrate the structure of the canal, or of any other organ, become, as I have since found,
denuded of this covering as they enter, and then seem to be formed only of two tissues,
_ the spiral and mucous,—if, indeed, there be not also, as I have reason to think there is,
an extremely delicate serous, or basement membrane, closely adherent to, and uniting the
coils of fibrous tissue, on its external surface. The tracheze which penetrate the muscular
layer of the canal terminate in the glandular or adipose layer, where a few of the branches
anastomose; but, as elsewhere stated$, « they do not ramify in the internal or mucous
membrane.” The ultimate divisions of these tracheæ are always distributed separately,
and do not anastomose. They end in extremely minute, filiform, blind extremities, as
noticed by my friend Mr. Bowerbank, F.R.S. This I find is their condition in all struc-
tures, in the nervous and tegumentary equally as in the glandular and muscular.

These facts may, perhaps, assist us to understand the nature of the injection of the
tracheæ by M. Blanchard|, and also the mode of nutrition in insects;—the ultimate
branches of trache in the tissues of the alimentary canal operating, possibly, as absorbent
structures, and inducing the chylific fluid elaborated around them to flow, in its transit
outwards, along the channels formed by their loose peritoneal covering, into the regular
circulatory currents {],—a view which, in part,—so far as refers to the presumed absorbent
operation of the trachew,—was long ago held by Dr. Kidd, in his paper on the Anatomy

XI. Further Observations on the Habits of Monodontomerus ; with some Account of a
mew Acarus (Heteropus ventricosus), a Parasite in the Nests of Anthophora retusa.
By GEORGE Newrort, Esq., F.R.S., FLS. $c.

Read March 5, 1850.

AS some of the details of a paper on “certain Chalcidide and Ichneumonide,” which I
had the honour of communicating to the Linnean Society, in March 1849, drew forth, at
that time, the criticism and dissent of some entomologists who had paid considerable
attention to those groups, I was desirous, during the past summer, of repeating my ob-
servations, and, having the ascertainment of strict truth for my object, sought to correct,
if erroneous, whatever might have been questioned, and to confirm by further observations
what I had already correctly stated. Accordingly, on the 16th of September last, I
revisited the spot at Gravesend, where, two years before, I discovered the larvæ which
proved to be those of Monodontomerus, and of which an account was given in the paper
above referred to. i 4

On this second occasion I had the good fortune to obtain an abundance of these larvæ.
Some idea may be formed of the number discovered by the fact that I brought away with
me two hundred and forty-seven specimens, independent of many that were accidentally
lost in the search. These larv were found, as on the previous occasion, in the closed cells
of Anthophora retusa, either in those which still contained the larva (Tas. X. fig. 1) or
nymph (fig. 2) of that bee, or in others in which the original inmate had been destroyed.
The number of larvæ of Monodontomerus found in the first five cells opened was nineteen
in the first; twenty-three in the second; thirteen in the third ; nineteen in the fourth,
and thirty-four in the fifth. In each of these cells I had full proof that the parasites had
fed on the Anthophora itself, as stated by another observer in correction of my first sup-
position, and as I had already been convinced by examination of the organs of nutrition.
The emptied and dried-up tegument alone was all that remained of the body of the
original inhabitant in each cell. In order however that there should be no mistake on
this fact, I removed three of the cells, which contained larvæ of Monodontomeri, without
opening them further than to ascertain the presence of the parasites, and placed each in
a separate small box to examine the contents at leisure, and more accurately than I could
do on the spot. This examination was made on the following day, and each cell was then
found to contain the dried-up remains of a single larva of Anthophora, with a variable
number of the larvæ of Monodontomerus,—nineteen in the first cell, twenty-three in the
second, and thirteen in the third as just stated. In neither of these instances had the
parasites been contained or fed within the body of the bee-larva, but had exhausted it
from without, and had drained the body of its contents in the same way as the larva of
Paniscus drains that of the body of the caterpillar. In those cells in which the parasites
were of largest size, the remains of the bee-larvze had been most completely exhausted ;

while in two of the cells the tegument was still soft, and not quite emptied, but in each
02

96 MR. NEWPORT’S FURTHER OBSERVATIONS ON

instance it was shrivelled up and lay at the larger end of the cell. In a fourth cell, which
I took home with me almost entire, there were eighteen larve of Monodontomerus, and
the remains of a nymph of Anthophora. In this cell the parasites were scarcely more
than one-half grown, and the remains of the nymph were very complete. The head, limbs,
and parts of the mouth were still uninjured, but the thorax and abdomen were nearly
emptied. The parasites had pierced the body in both these regions, and were ranged on
each side of it. This specimen therefore confirmed Mr. Smith’s statement*, that the
Monodontomeri feed on the nymph of the bee, as I had previously shown that they feed
on the larva. It also afforded the fullest confirmation of my original opinion,—that these
parasites are external feeders,—a view to which I was led,—not, as erroneously stated by
Mr. Westwood, in the printed Proceedings of the Society, from the simple fact of my
having found that the bodies of these parasites have an armature of hairs; but, as ex-
plicitly stated in my papert, as read to this Society, because I have never yet found hairs
on the bodies of internal feeding parasites. External feeders, nevertheless, may be deficient
of this armature, as in the instance of Eulophus Nemati cited by this observer.

As the whole of the tegumentary portion of the body of the nymph of Anthophora,
obtained by myself, like that of the larva, remained in the cell, although partially
'shrivelled up, there seems to have been some error also, in part of Mr. Smith's observa- -
tions, as given in the following words$: “ When first observed the pupa of the bee was
about one-third consumed, and at last not a vestige of it remained ; all that the cell
contained, besides the larvæ, being a small portion of yellow dust, or small granules."
I cannot help regarding this statement as having originated in oversight or mistake, as in
every cell which I have examined the tegumentary remains of the destroyed bee-larva
have invariably been present; while in neither of the many cells which I opened very
carefully at the moment of finding them in their natural haunts, nor in the four which I
preserved for still closer examination at home, could I detect any “yellow dust or,gra-
nules.” There were only the parasites and the more or less dried-up tegumentary remains
of the destroyed insect. Neither was there any “yellow dust or granules" in the cell -
with the nymph of Anthophora. All which this contained were the parasites and the
remains of the nymph; together with the larva skin it had thrown off on assuming this
condition ; while the larger end of the cell was coated with a perfectly smooth layer of

ejecta; a coating which, as I formerly stated, it always gains after the larva has ceased
to feed, and before it changes to a nymph. I mention these circumstances the more par-
ticularly, because, as Mr. Smith’s remarks on Monodontomerus were communicated to the
Linnean Society in correction of mine on this insect, previously read, and as the abstract
of that paper has since been published in the « Proceedings,” it is incumbent on me to
— his statements with care, and to show in what we agree or differ. In his com-
munication to the Society, he states that he obtained the larve of this insect “in the
summer of 1848|,” and also remarks:—“I then made a drawing of the larva of the
rg I enclose.” On this drawing is written the following confirmatory note :—
ound feeding on the pupa of Anthophora retusa, July 1848.” The following

_ THE HABITS OF MONODONTOMERUS. 97

passage from the Proceedings of the Entomological Society*, printed in 1848, records the
exhibition, by myself, at that time, of specimens of the Imago insect, reared from the
larvee mentioned at p. 67, found on the 12th of September, 1847 :—* July 3rd, 1848.
Mr. Newport exhibited a new species of the genus Monodontomerus, belonging to the
family of the Chalcidide, reared from larvee which he had found in the nests of Antho-
phora retusa. He proposed for it the name of M. nitidus."
Thus my recent observations on Monodontomerus in its natural haunts, supported by
further examination of the anatomy of its digestive organs (figs. 3 & 4), have fully
confirmed my former opinions as regards the nature of the larva, that it is an external
and not an internal feeding parasite, and that some remains of the destroyed bee-larva
are always found in the cell. They confirm too the observation that the bee-nymph
is preyed upon; as well as that the larva of Monodontomerus is carnivorous; but they do
not support the statement, and the inference to be deduced from it, that “not a vestige”
of the bee is left in the cell. Further, they give strength to the opinion I have advanced
respécting the mode and time of introduction of the eggs of the parasite; viz. by perfora-
on of the cell. The circumstance of the bee-nymph being preyed upon, as well as the
_ larva, goes far to establish this, as in each instance the parasites with the nymph were
scarcely more than one-half grown. This seems to show that they had been introduced,
at the time of change, or at a very late period of the larva state. . There seems reason
to believe also that the eggs are seldom conveyed into the cell until long after this has
been closed, and consequently when the bee-larva within has far advanced in growth, as
in no one instance could I discover a particle of the food of the larva.
- Being desirous, however, of ascertaining facts by direct observation, rather than of
arriving at views by inference, I placed, on the 17th of September, twenty of the most
healthy middle-sized specimens of the larval Monodontomeri with a single larva of 4 Who:
phora, in one division of a glass tube; and twenty smaller specimens, with a nymph of
this bee, in another division of the same tube, separating the two sets with a piece of
sponge, and closing the tube with acork. On the following day the parasites had arranged
themselves with their heads towards the body of the larva, but they did not appear to have
commenced their attack, probably from a cause which I shall presently mention. On the
next day, however, the third of inclusion in the tube, I saw one individual ua m

still further discoloured, and many of them were dead, and all were covered with the
bladder-like bodies in greater abundance.
On examining other specimens of these larvæ, which I had placed in separate bee-cells,
I found that these also were in a similar condition; and on inspecting my collection of
larv and pupæ of Anthophora, these too, to my utter astonishment, were covered in the
same manner. 1 noticed also that the vesicles first observed on the larv in the glass tube
had become much larger, during the past two days; and on inspecting them very carefully
with a lens, I found that the bladder-like bodies were either the nidi of parasites, or living
parasites themselves attacking and exhausting the enemies of the young bee, as the bee
had been attacked by them (fig.5). Thus in less than eight days from the time when my
specimens were collected, the whole were irretrievably destroyed by objects which now
covered them in multitudes, but which at first were so microscopic as entirely to escape
observation. As it was now evident that my whole collection of larvee of Monodontomeri
would soon entirely disappear, I placed a number of them, together with the parasites that
covered them, in spirit for future examination. Out of nearly two hundred and fifty
specimens of these, and of a still greater number of larvee and nymphs of Anthophora, the
result of the persevering labour of several hours’ search, I was not able to save even
a single specimen. Wherever I placed them in the room appropriated to my investiga-
tions, they became covered with these microscopic enemies, whether secured in wooden or
tin boxes, or covered earthen pots. I now began to suspect the cause of this mischief.
During the time I was collecting the larvze, on the 16th of the month, I found some bee-
cells nearly filled with a large mass of vesicle-like bodies. These were completely new to
me. ‘The body of the bee-larva seemed to have been changed into this mass of spherical
nondeseripts (fig. 1), which, although quite distinct from each other, were aggregated
together, and somewhat resembled a microscopic bunch of grapes. Each of the bodies was
opake and clouded on its upper surface, and seemed to include other bodies. On its under
surface it was clear and transparent. They varied greatly in size, from that of a minute
pin’s head to nearly one-sixteenth of an inch in diameter. Having found several of the
cells filled with them, I collected these cells, for the purpose of ascertaining, if possible,
the nature of their contents. I found also one cell in which these bodies, as well as the
remains of the bee-larva, were almost dried up. The instant this cell was opened and
exposed to light, I noticed, on examining the interior with a lens, that it was partly filled
with what looked at first like dust ; but more closely observed this was seen to consist of
crowds of little brown objects (fig. 6), in a state of the most vivid and incessant motion.
These were so exceedingly minute that I could only recognise them to be living creatures
by means of the lens, and even then with difficulty, without being able to distinguish their
ee of the same colour as the clay-soil of the nest. They reminded me

the cell. The majority, as was afterwards proved by what I have just stated, had crept
out and distributed themselves over the room. Many probably had escaped into my other
collecting boxes while being conveyed home.

It was in the afternoon of the following day that I placed my larvæ of Monodontomerus
with that of the bee, in the closed glass tube, as already mentioned; so that, in all pro-
bability, it was during the few hours that my boxes which contained the young bees and
their parasites remained near that which enclosed the cell, that these little creatures
escaped and affixed themselves to the larvæ. "This was at a stage of existence when the
whole brood of nondescripts had been recently matured, and probably soon after there had
been communion of their sexes (?) within the cells,—if, indeed, males, which I have not
been able to identify, are produced,—and before the bodies of the fertilized females, which
the vesicles in the other cells, as well as those afterwards found on my larvæ, all proved
to be, had begun to be enlarged. These diminutive objects I soon found to be Acari
of a new type (fig. 7).

I have said that the bladder-like bodies were fertilized females. There seems to be
full proof of this in the following circumstances. At the time when I enclosed the larval
Monodontomeri in the glass tube, the temperature of the atmosphere of the room was above
55° Fahr., and very frequently during the ensuing fortnight was more than 60° Fahr. The
growth of the Acari was then very rapid. Within ten days from the time when they affixed
themselves, indeed within eight from my first observing them, the bodies of some were
enlarged to the size of the head of a small pin, and the ova within them were readily and
distinctly identified with the microscope. They increased in bulk most rapidly during the
first fortnight, after which their enlargement was less perceptible. On the contrary, I fancied,
but was not certain, that they became somewhat smaller. Several of them at first were
more opake, and afterwards became of a brownish colour. In about three weeks, during
which time the tube had been frequently exposed to the sun, there was full proof that some
of these specimens had produced young. The interior of one end of the tube was then
‘covered with a great number of Acari, such as I had originally seen in the bees’ nest (fig. 6) ;
not with the abdominal portion of their bodies enlarged, but short, narrow, and somewhat
tapering at its extremity. These little beings appeared to have only recently come forth,
as they were of a much lighter colour, and somewhat smaller than those which were found
in the cell. Some of them placed on a micrometer plate measured only sixteen thousandths
of an inch in length. The glass tube being tightly stoppered with a cork, so that nothing
could enter or escape, it was fair to conclude that these were the young of some of the
females attached to the bodies of the larvæ, although I neither saw them come from their
parents, nor was able to find that any ova had been deposited from which they might have
been hatched. Nevertheless they had already undergone the change common to the tribe,
—that of obtaining an additional pair of legs, as they had the full complement—four
pairs. It is well known that this is not the condition in which Acari are usually pro-
duced, each having at first but three pairs. It remains for future inquiry, therefore, to
show in what condition this species first makes its appearance,—whether ova are at
any time deposited and afterwards become hatched, whether ova are produced at one
season and living young at another, or whether, as I have most reason to conclude, the

100 MR. NEWPORT’S FURTHER OBSERVATIONS ON

species is viviparous. The females, already fertile when they quit the cell, move at first
with great celerity, the abdomen being then the smallest portion of the body. But as
soon as they have penetrated into other bee-nests, and affixed themselves to the bodies of
the inmates, and begun to drain them of their fluids, the posterior three or four segments
of the bodies of the little nondescripts become rapidly more and more enlarged, and
assume the spherical bladder-like appearance seen on the bee-larva or its parasite. This
enlargement is carried to such an extent, that this portion of the body of the gravid
Acarus soon becomes at least ten, or twenty, or even more times its original size, and
at first sight seems alone to constitute the entire being (fig.8). The Acarus in the
meantime loses its power of locomotion, and becomes affixed to one spot, or changes
its place so little, and so imperceptibly, as to appear to be immoveable. Gorged with
the nutriment imbibed, it sinks into a state of almost vegetative existence, and seems
to lose all the energy and power of motion it originally possessed; strongly reminding
us of a similar degradation of animal function which the active little Meloé undergoes
before it attains its full growth as a larva; and which the Stylops also passes through,
before it is re-developed in the one sex as one of the most lively of beings, or diverges
still further in the other, from the usual condition of an animal, as a mere nidus for
the production of new existences. This approach to the vegetative type is the form
in which these pregnant Acari are found in the bees’ nest, crowding over, and hiding the
remains of the larva they have destroyed. From all which I have as yet been able tó
observe, these Acari appear to become nidi for the development of the eggs formed within
them; and I have much reason to believe that, as in Stylops, the young pass through their
earlier stages within the bodies of their parents, and escape from them in an active con-
dition, possibly at first as hexapods. The common cheese mite, according to Lyonnet, pro-
. duces living young at some temperatures, and ova at other more reduced ones; and this,
as we know, is the case with the whole tribe of Aphides among insects. Whether the
female Acari perish before their young are hatched, or whether, as I believe, the birth of
these is the immediate prelude to their parents’ death, I have not yet ascertained. It is -
certain, however, that the largest-sized females become discoloured earlier than the smaller,
and this too I believe in proportion to the temperature of the season. The temperature of the
season, or of the locality in which the Acari are placed, greatly influences, not only the
more or less rapid enlargement of the bodies of the females themselves, but, as I believe,
the hatching of the ova within them. This has been proved to me by the fact that a very
large proportion of the females, with the abdomen of full size, early in the autumn, but
when the temperature of the season was gradually subsiding, —and which I was careful
not to expose to the sun,—have remained alive during the winter to the present time, a
period of five months, without producing young, or, so far as I can discover, depositing
any eggs. In some of these specimens which I examined a few days ago, I found the
ova still immature, and even the germinal vesicles within them still present, and easily
detected. "We may conclude, therefore, that a rather high temperature is required to — .
complete the development of the ova and produce the embryo. This high temperature is —-

always found during summer in the natural haunts of the Anthophora. The clay banks e

in which these insects construct their cells become heated by exposure to the morning and |

-

mid-day sun, sometimes to as much as 84° Fahr. at a depth of one inch and a half, as I
have elsewhere shown*, and much of this heat is retained throughout the whole twenty-
four hours; so that, in all probability, the growth of the pregnant Acari, and the hatching
of their ova, then proceed very rapidly; while, on the contrary, these, as well as the
changes of the bee-larvæ, are entirely arrested during winter. This will explain, what
might otherwise seem to be discrepant, that some young Acari were produced after expo-
sure to the sun, and in a warm room in October, while others not exposed to the sun, and
the season becoming colder, have remained until the present time undeveloped.

Having stated thus much respecting the economy of this microscopic parasite, I will
now endeavour to describe it, and to show that it constitutes a new genus of its class. It
belongs to the section Tyroglyphus of Latreille and Gervais, the tribe Sarcoptides of Koch,
whieh has the Sarcoptes scabiei of the human subject as its type, and which includes also
the Demodez folliculorum of Simon and Owen, a parasite in the follicles of the hairs in
Man. It is most nearly allied to Koch's genus Dermaleichus, most of the species of which
are parasites on birds; but it is perfectly distinct from that, as well as from the genus
Trichodactylus of Dufour, a parasite on the Mason-bees of the genus Osmia. It is equally
distinet from the Ansetus of Dujardin, which also is a parasite on bees, although it
approaches these two genera in certain particulars. It resembles the latter in the general
elongated form of body and in the size of the haunches of the legs; but it differs in the
body being articulated throughout, in having a somewhat cordiform moveable head, the
prothorax distinct from the trunk and abdomen, and the anterior pair of legs palpiform,
while the three posterior pairs are equal, and terminated by four-jointed slender tarsi, the
last joint in each being cordiform and pad-like, as in the larva of Stylops. In this latter
respect it has affinity with the genus Hypopus of Dugès, as it has also with Trichodac-
tylus in the legs being covered with a few very long hairs.

With regard to the change and enlargement of the body in the female sex of the Acarus,
every one will remember that its parallels are to be found amongst true hexapods, in the
Termites and the Pulex penetrans.

The characters I would assign for the new Acarus are :—

102 MR. NEWPORT ON THE HABITS OF MONODONTOMERUS.

‘The importance of a thorough examination of these microscopic pests is at once evident,
in the fact that the type of the family to which the whole of them belong is the noisome
parasite of the human subject; that another, as yet undetermined form of the same tribe,
is thought by some to be connected with one of the most fatal ailments of our frame,
dysentery ; that two distinct Sarcoptes yet undescribed affect the horse and sheep ; and that
even the common sparrow, and our little pet the canary, are infested by others of this class.

When, therefore, we reflect on the ailments which these produce, and on the diminutive
size of the creature I have just characterized, and which in its effects are so destructive
to other tribes, and bear in mind that this mere speck, this particle of dust, is organized
for all its purposes as completely as the most perfect of any of the whole sub-kingdom to
which it belongs,—even to the flexor, the extensor, and the rotator muscles of its truly
atomic limbs (fig. 9) and tarsi,—while the entire body of the creature, when first produced, |
measures scarcely more than sixteen thousandths of an inch in length ;—and then call to
mind that the mere foot alone of the Dinornis, or of the Palapteryx, the ancient colossal
birds of the Antipodes, measures, as shown by the most renowned anatomist of our age,
Professor Owen, more than twelve inches—nearly seven hundred and fifty times the whole
size of this little body :—who can but feel astonished at this range of Creation ?—who can
but feel that the study of natural history,—not as the amusement of an hour, but as a
sober contemplation,—must tend to exalt as well as to expand the human intellect; and
that the most microseopic atom of organized life, considered as part of the world, is as
deserving of our fullest attention as the most gigantic ?

XII. On the Development of the e. and Elaters of Marchantia polymorpha.
By ARTHUR Henrrey, Esq., F.R.S., F.L.S. Se.

Read November 20, 1849.

M. MIRBEL^*, in the first of his celebrated essays on the structure and development of
Marchantia polymorpha, expresses himself in a note in the following terms:—* The `
origin of the elaters would, I think, be a curious discovery. I should not be astonished
if most direct and positive observations led one day to the conclusion that these organs
are but one of the numerous modifications which the utricles undergo. Such a result would
decide many questions which we have long been endeavouring to solve.”

In his second memoir on the same subjecti, he announced the fact that he had
observed the development of these bodies from the utricles; and’ the progress of vegetable
anatomy since that time has made it a matter of certainty, that all the forms of the
elementary tissues are to be referred to a cellular type. But so far as I can discover, all
observers, who have hitherto investigated the development of the spores and-elaters of the
Hepatice, have overlooked certain important points. In the course of a series of observa-
tions on the development of spores, made in reference to the theories of cell-development
in general, my attention was strongly attracted to a very peculiar condition which I met
with in the young sporangia of M. polymorpha, and as I can find no notice of the phe-
nomena in the works of previous authors, I am induced to publish an account of them. _

The spores of Marchantia are produced, as is well known, in sporangia enclosed in
peculiar receptacles or involucres situated at the base of the rays of the stellate body
borne on the pedicel, on the under side. It is unnecessary to notice the characters pre-
sented by the envelopes of the sporangia, as these have long since been well described
and figured; the whole course of development of these parts is beautifully illustrated in
the memoirs of M. Mirbel already referred to.

The first indication of the production of the sporangia is the appearance of the organs
called pistillidia, exactly resembling those of the other Hepatice and of the Mosses.
Within the enlarged base of the pistillidium a small globule of a green colour is soon met
with; this is the nascent sporangium, and in its subsequent development it enlarges
within the expanding cavity of the pistillidium, acquiring a pyriform shape, and exhibit-
ing at one period a little filamentous process at its apex. The nature or import of this
process I cannot make out, but I found it also in Spherocarpus terrestris, and it is

represented in the figures of most of the Ricciacee in Lindenberg’s Monograph*.
While the enlargement of the nascent sporangium tends to fill up the cavity of the pistil-
lidium, the single layer of cells composing the wall of the latter is developed still more
rapidly than the sporangium ; its elongated neck disappears, and it is found in the nearly
ripe fruit as a loose cellular envelope immediately enclosing the sporangium ; when quite
ripe it bursts above, exhibiting irregular teeth. The envelope of the globular sporangium
of Spherocarpus terrestris appears to me identical in its nature, but it remains green
and does not burst: a little orifice in the apex, corresponding to the base of the neck-like
portion of the pistillidium, may permit the escape of the spores ; otherwise they can only
become free by the decay of this involucre.

The walls of the sporangia of Marchantia are composed of a single layer of cells, at
first almost cubical, and filled with chlorophyll-vesicles ; but as they enlarge they become
elongated in the vertical direction, the chlorophyll disappears, and spiral fibres, or more
frequently annular bands, make their appearance upon the walls. These bands are of a
flattened riband-like form, and of a yellow colour, the membrane of the walls of the
perfect cells is hyaline, and the cavity contains only a few yellow granules. This structure -
of the wall of the sporangium of annular fibrous cells is analogous to that of the Junger-
manme and to the spiral tissue of anthers, and is for a similar purpose, namely by its
elasticity to cause the rupture of the mature parts as they become dried by evaporation.

No similar elastic tissue presents itself in the Riceiacee, in which moreover the elaters
are absent ft. |

In all the foregoing points, my observations agree perfectly with those of M. Mirbel.
Before proceeding to detail what I have seen in the development of the spores, it will be :
as well to give an account of what had been observed by preceding authors.

Mr. Griffith, in a note appended to M. Mirbel’s first memoir t, stated, with regard to
Targionia hypophylla, that “in the young ovaries the elaters are not visible, and the
seminules, united by a gelatinous substance, form as it were a continuous mass. They
then seem to be vesicles filled with corpuscules, although when mature each is evidently
a cellular body.”

M. Mirbel$ remarks on the same plant :—“ The nascent seminules are contained in the
cells of a tissue which fills the young ovary; each cell contains three or four seminules.
As the ovary advances in age, its internal tissue becomes dislocated, and is broken up
into as many distinct utricles as there were cells, so that the little groups of seminules
each have a utricle for an envelope.

“ The seminules, young or old, are themselves simple utricles, which contain colourless
spherules attached to their walls. This observation does not agree with the opinions of

- Griffith ; according to him, the mature seminules are formed of cellular tissue.

“ The elaters do not display themselves until some time after the dislocation of the tissue.
They are slender, colourless, perfectly closed tubes, always with blind terminations (en

* Lindenberg, Monographie der Riceien, Nov. Act. Acad. Nat. Cur. xviii.

T According to M. Mirbel, the cellular tissue of the sporangium of Targionia (which has elaters) is not annulated,

but the cells have half-rings on the internal and lateral walls, like the Jungermannice.

T Loc. eit. p. 371. $ Loc. cit. p. 371-2.

AND ELATERS OF MARCHANTIA POLYMORPHA. 105

cecum), and often curved like a hook. At this epoch they contain colourless spherules
which subsequently disappear.

“When the elaters are older they have acquired a yellow colour, and one would say that
each served as a sheath to two long, very narrow bands, rolled concurrently and parallel,
like a corkscrew, with very loose convolutions. There is an optical illusion here; the
bands do really exist; but instead of being free in the interior of the tube, they are an
integrant part of it.”

Tn his second memoir*, M. Mirbel gives an account of the development of the elaters
of Marchantia polymorpha :—* It (the sporangium) is at first merely a mass of tissue,
composed of utricles filled with green spherules. But when the pistil had attained the
degree of development last indicated, the internal utricles had become detached from one
another, while those of the superficies remained closely united, and constituted a balloon-
like sac, completely closed, in which the internal utricles were imprisoned. These were
not all of one kind; some had been developed into long. slender tubes, pointed at both
ends, which most certainly still adhered by one of these ends to the internal surface of
the sac; the others, in much larger numbers, polyhedral at first, had passed into a
spherical form by the gradual rounding off of their angles. To each utricle elongated into
a tube, a double series of utricles were feebly adherent. Both kinds were still filled with
green spherules.

“ As they advanced in age, the utricles composing the sac and those elongated into tubes
underwent modifications, to which I must draw the attention of physiologists.” [Three
or four flattened rings, arranged parallel, appear on the walls of the cells of the sac; these
become better defined, and at last acquire a yellow colour. My own observations on this
point agree perfectly with those of M. Mirbel.] “ The utricles elongated into tubes only
differed from the others in form at first; they then possessed a delicate, simple, diapha-
nous, entire, uncoloured, membranous wall, but they soon became thickened, lost their
transparency, and became marked all round, throughout their whole length, with two
parallel streaks, closely approximated and describing helices. Then, increasing in size,
their streaks became slits which cut the wall of each, from one end to the other, into two
filaments, and the convolutions of these filaments separated, resembling the turns of a
corkscrew. Finally, the two filaments acquired a rusty yellow colour, and the metamor-
phosis was so complete, that if I had not followed the modifications, step by step, I
should now be afraid to say that these two filaments were at first one simple utricle; but
the fact is constant, and I am convinced that whoever repeats the series of my observa-
tions, with the firm determination to let nothing escape which it is possible to see, will
arrive at the same result as myself.”

Bischoff gives no account of the development of the elaters, and evidently mistakes
their origin, for he sayst:—* Where we find among the spores, elaters which, arising
originally as elongated cells from the internal wall of the sporangium, lie among the
parent-cells of the spores, I should rather compare them to the cellular filaments which
occur in the capsules of Mosses, e. g. in Buxbaumia, Funaria, &e., running across
between the outer and inner membranes of the sporangium; and in Polytrichum, in part

* Loe. cit. p. 382. + Bemerkungen über die Lebermoose ; Nova Acta Ac. Nat. Cur. xvii. p. 909 et seq.

106 MR. HENFREY ON THE DEVELOPMENT OF THE SPORES

between the latter and the columella; while in the Hepatice where the inner membrane
is wanting, they run in free among the parent-cells of the spores.” __

Von Mohl* gives no account of the development of elaters; with regard to certain of
his views on the development of the spores, I shall allude to the papers just cited,
further on.

Gottschet does not describe the development of the elaters, nor indeed the earlier
conditions of the spores.

I now proceed to the results of my own researches on this subject.

The little green cellular body which is found within the pistillidium increases in size,
and in the course of its growth its cells are differently modified; the external layers, over
the whole surface, adhere together into a membrane, which becomes the spiral-celled
membrane of the capsule; the cells contained within this layer produce the spores and
elaters. I have not been able to determine satisfactorily the earliest conditions of the
enclosed cells. In the youngest specimens I found it impossible to ascertain the true
nature of the structure, on account of its delicacy, but I believe that Bischoff is certainly
wrong in supposing the young capsule to be filled with a mucilaginous fluid (brei).
Mr. Griffith and M. Mirbel state, that there exists a continuous tissue in Targionia ; and
Mr. Fitt} states that the apparently gelatinous contents of the capsule of Spherocarpus
terrestris exhibited a cellular appearance, when dried up, on the object-glass. From these
facts and from analogy, I am inclined to believe that the young capsule is at first
formed of a continuous cellular structure, and that the cells of this tissue become parent-
cells, producing new cells within them, which they set free by becoming dissolved;
exactly as occurs in the production of the parent-cells of the pollen-grains, in the con-
tinuous cellular tissue of anthers.

However this may be, it is certain that cells do become free in the cavity, producing the
elaters and spores, and the condition and form in which they present themselves is very
remarkable. M. Mirbel states that he found minute elongated cells, the young elaters,
mingled with small squarish cells, the spores, which afterwards acquired a globular form.
It is evident from this that he missed the earlier stages of the metamorphoses. I found
the young capsules to contain elongated cells alone, and these of two sizes. The whole
cavity of the capsule was filled up by elongated cells arranged side by side, and apparently
radiating from the centre; a portien of these elongated cells were narrow, and were
interposed between much longer and broader ones of the same form, in such a manner
that scarcely any interspaces existed. The narrow cells are the young elaters, while the
broader ones are the parent-cells of the spores. The subsequent development I have
followed out clearly. The young elaters are elongated, slender tubes, attenuated toward
each extremity; they are at first filled merely with an almost colourless, coagulable pro-
toplasm. After a short time starch-granules make their appearance in them, the true

nature of these bodies being readily determined byiodine. The starch-granules frequently
lie within the young tube, in such a manner that they may easily be mistaken for the
rudiments of the spiral fibres, but they are quite distinct from these, and disappear before
the fibres begin to be deposited. I believe that the accounts given by some authors of
the formation of spiral fibres in spiral vessels from rows of minute granules are incorrect,
and have arisen from observation of starch-granules lying in rows, often running obliquely
across the tubes. As the tubes grow they enlarge more in length than in diameter, and
appear as very long, slender filaments; the starch-granules, and finally the protoplasm
disappear, and faint streaks, denoting the nascent fibres, are at length to be perceived
upon the walls. These gradually become more and more distinct, until in the mature
elaters they present themselves as strong, flattened bands. In Marchantia there are two
fibres, and the ends of these are confluent at the extremities of the tubes in which they
_ are contained. More properly speaking, therefore, the fibre is one endless fibre twisted
upon itself; the best possible condition of structure for the purpose. We may represent
the condition of the fibres by a piece of string doubled, and with its ends tied together ;
this, when twisted up, unrolls immediately one end is set at liberty ; or, if both ends are
let loose at once, the whole piece springs away as it unrolls, just as the elaters of Marchantia
spring out when the capsules burst. In unrolling the fibre it tears up the membrane of
the wall of the tube, and when the elaters are examined after they have been discharged,
the fibres are found somewhat unrolled, and the torn membrane is often no longer to be
detected.

While the elaters are passing through these stages, the larger elongated cells exhibit a
very remarkable series of changes, which appear to differ from everything that has yet
been observed in analogous structures. They are at first filled, like the elaters, with a
delicate, colourless protoplasm, in which float exceedingly minute granules ; this substance
is coagulated even by water, and still more strongly by alcohol, acids, and iodine. It is
apparently the same substance that occurs in all young cells which increase by self-division.
I have found it unmixed, as here, in young hairs, in the parent-cells of pollen before the
formation of the septa, in the confervoid body which grows out from the embryonal vesicle
of the Orchidacee, in the Yeast Fungus, &c. In most cells it very soon becomes mixed
with starch and chlorophyll vesicles. |

“The elongated cells soon exhibit transverse streaks of a lighter colour, from the proto-
plasm separating into a number of portions, and cross membranes are produced at these
places, dividing the tubular cells into a row of cells, all of square form, except the two end
ones, which are attenuated toward the free point, and thus appear triangular in the side
view. I could not make out whether the septa were formed by gradual growing in of the
membrane; if so, the process must go on very quickly. Neither could I detect a double
membrane; but this must exist, as the cells afterwards separate from each other at these

= points. Vertical septa often occur, producing a double row of cells from the original tube.

M. Mirbel appears to have made his earliest observations subsequently to the breaking up
of these rows of cells, and thus to have missed them. They are a constant phenomenon,
and I know of no analogous structure, unless we compare them with the single rows of
cells which first appear in the tissue of the anthers, and by subdivision become the parent-

108 MR. HENFREY ON THE DEVELOPMENT OF THE SPORES

cells of the pollen; but the cases are very dissimilar, since in Marchantia these rows of
cells are produced from free tubular cells, in great numbers, after the dislocation of the
tissue of the cavity of the sporangium.

About the time the cells separate from each other, the contents undergo a great change,
which exactly resembles the change that occurs in the contents of the parent-cells and
special-parent-cells of pollen when the formation of free cells is about to take place in
their interior. The mucilaginous matter, or protoplasm, which was at first almost colour-
less, acquires a deep yellow colour, becomes much thicker, and exhibits a quantity of
globular bodies which look like drops of oil. These globules are often described as gra-
nules, and some authors have mistaken them for drops of oil; others regard them as
vesicles or vesicular cavities in the protoplasm ; I believe them to be globular drops of the
yellow protoplasm; they sometimes become confluent, but are not oil, since they acquire
a brown colour, like the rest of the contents, with iodine, and are not dissolved by ether.
They may acquire the appearance of vesicles by becoming coagulated on the surface, as
this yellow protoplasm is readily coagulated even by water, but very strongly by alcohol
or acids. The cells become filled with globules of this kind of all sizes, sometimes occu-
pying half the cavity of the cell, but neither before nor after their formation did I meet
with nuclei.

Soon after the cells become free, the yellow contents exhibit lighter streaks running
across, which denote that they are separating into four portions; these are at length com-
pletely isolated and become coated by a proper membrane. They are the spores, and by
the solution of the membrane of the parent-cells they beeome free. When free the con-
tents become again clear and almost colourless, then the membrane becomes thickened
and of a bright yellow colour, and the contents are changed into globules of pretty regular
size which fill up the cavity. Inever saw any trace of septa dividing the parent-cells into
chambers, such as we meet with in the special-parent-cells of pollen. When the parent-
cells in which the contents had parted into four portions were ruptured at one place, all
the contents passed out and the membrane remained as a simple sac. When iodine was
applied at the same stage, the portions were strongly coagulated, while the parent-cells
expanded, but no trace of septa appeared.

Mohl states that the parent-cells of the spores of Anthoceros levis are first divided into
four chambers by septa, and that the same occurs in Jungermannia epiphylla, in the last of
which the parent-cell divides into four separate cells, each containing a spore ; which con-
dition Mirbel asserts to be universal in the formation of spores. I could find no evidence
of it; and Gottsche says, with regard to Haplomitrium Hookeri, that the empty parent-
cells present marks which make them look as if they were chambered, but that all the
spores pass out at one opening. It is quite possible that the enlarging spores cause the
marks by their pressure against the enclosing membrane. -

I could only distinguish a single coat to the ripe spore, and this grows out into a tube
at one point in germination. The entire spore with its contents becomes colourless
during this process, the yellow colour and the globules disappear, and after a short time
chlorophyll-vesicles appear, which, when iodine is applied, are seen to be imbedded in a
coagulable, colourless protoplasm. Mohl states that the spores of Anthoceros have two

AND ELATERS OF MARCHANTIA POLYMORPHA. 109

coats, while Gottsche says that Pellia and Blasia have a single-coated spore, and Fim-
briaria and Preissia apparently have two coats. I believe that this point can only be
determined with certainty when the spores are germinating, and observation of this pro-
cess leads me to the result that the membrane is simple in Marchantia polymorpha.

In conclusion, I cannot refrain from directing attention to the striking circumstance,
that I met with no nuclei throughout the whole course of development. Mohl, in his
essay on Anthoceros levis, describes a series of phenomena connected with the appearance
of nuclei, of which I saw nothing in Marchantia; neither did I see any nuclei during the
development of the spores of Spherocarpus terrestris, which I partially traced last spring.
Sometimes the globular bodies in the yellow protoplasm present appearances which might
be mistaken for nuclei, but careful investigation always led me to believe that these
appearanees were deceptive; and as I obtained clear and well-defined views of all the
various stages, with fully sufficient magnifying powers to see nuclei if present, I am com-
pelled to deny their existence here.

The main point, however, to which I wish to direct attention in this paper, is the
singular manner in which the subdivisions of the cells take place, in order to produce the
very dissimilar forms of long filiform elaters and spherical spores, from a tissue originally
homogeneous.

XIII. The Ternstræmiaceous Plants of Hong Kong. By CAPTAIN adi 95th Reg.
Communicated by the PRESIDENT.

Read November 5, 1850.

CONSIDERING the great success of the Camellia Japonica as an ornamental green-
house plant, it appears remarkable that but little attention should have been paid to the
introduction into England of other plants of that order from India and China. Both the
Camellias and Gordonias are trees or shrubs of very great beauty, and of rather hardy
growth; in tropical climates restricted to elevations, where the climate bears affinities to
more northern temperatures; and in China they flower alongside of the Azaleas so
successfully introduced into England. Polypetalous, they hold out to the horticulturist
the probabilities of increased beauty through judicious and successful cultivation.

The species of Camellia at present best known in England has been principally intro-
duced from Chinese gardens. Without detracting from the good taste of that nation, in
having selected elegant species, and brought their flowers to a degree of improvement
which alone might have been expected from English industry, it is to be presumed that
many species (some of which have been described by Loureiro) remain, in the wilds of
Southern China, uncultivated. 3

The Chinese are in some respects bizarres in their admiration of plants; they have
their favourites, and they are permanent favourites; not the fashion of the day, but of
centuries; and these alone they cultivate, although we are acquainted, through Mr.
Reeves and through Mr. Fortune, with other plants of great beauty, which are less
admired by that nation. Should at any period English taste extend itself to others of
the Camellia tribe, we must principally look for them from the Celestial Empire. The

plants about to be described are indigenous to one small island.

Genus CAMELLIA, L.

1. CAMELLIA SPECTABILIS; arborea, folis lanceolatis acuminatis glabris crenatis sub-
tùs reticulatis, floribus solitariis magnis albis axillaribus et subterminalibus, sepalis
coriaceis fructibusque pomi magnitudinis sericeis.

Hab. in insulà Hong Kong, Sinarum, in sylvis. |

A small tree; flowering also as a shrub. Branchlets light ferruginous. Leaves
alternate, short-petioled, elongate-lanceolate, with a long acumination, crenated and
pellucid on the margin, coriaceous, smooth and shining; pale beneath and reticulately
veined. In dried specimens the leaves turn yellow like those of a Symplocos; they are

under 5 inches long by 14 lines broad. Flowers about 24 inches across; sepals 9-11,

imbricated, obtuse, yellowish green and very sericeous, coriaceous. Petals about 7,

white, roundish-obovate, emarginate. Stamens very numerous, gamboge-yellow. Style
Q2

112 CAPTAIN CHAMPION ON THE TERNSTR(EMIACEOUS

sericeous, splitting a quarter of its length into 3—4 styles. Ovary 3-celled, each cell
2-ovuled. Fruit the size of a small apple, retaining at base the persistent sepals, and like
them very sericeous. Seeds several, pretty large; the outer coating chestnut-coloured.
Flowers in May, and fruits in November. It is a very handsome species, quite distinet
from C. oleifera (Abel), of which I have seen specimens, through the kindness of Mr.
Bennett. The petals of dried specimens turn dark yellow. I have endeavoured to intro-
duce this species.

2. Camellia Japonica, Linn.

Of this but two trees are at present known in Hong Kong, growing wild, and discovered
by Lieut.-Colonel Eyre, of the Royal Artillery. It is a moderate-sized smooth tree,
loaded in October with single pink flowers. The fruit is smooth and much smaller than
in the last species, rather above an inch in diameter. The petals, about 7, adhere at
base into a ring, and are soon detached and fall off. The sepals are slightly sericeous,
and the leaves more elongate than in most of the cultivated plants.

3. CAMELLIA SALICIFOLIA; arbuscula, ramulis pubescentibus flexuosis, foliis subsessilibus
elongato-ovatis acuminatis serratis pubescentibus, floribus parvulis albis, sepalis
acuminatis pubescentibus, capsulis glabris parvis rostratis 1—3- sæpiùs mono-
spermis.

Hab. in insula Hong Kong, Sinarum, in sylvis.

Sepals 5-7, subulate, hairy exteriorly, imbricated and subtended by imbricated, hairy
bracteoles. Petals 5; white, oblong-ovate to obovate, gamopetalous at base, sericeous
exteriorly. Stamina very numerous, in four rows; outer rows united into a tube;- two
inner with nearly free filaments. Style hairy, simple, elongate. Stigmas 1-3, filiform.
Ovary hairy, 2-3-celled, each with a double row of 3 anatropous ovules. Capsule roundish-
rostrate, usually by abortion 1-seeded; rarely 3-celled, 3-seeded. Leaves nearly sessile,
softly hairy. Flowers nearly sessile, about an inch in diameter. Fruit from 5-7 lines in
diameter. Flowers pendulous, scentless, white. It is a rather pretty undertree with
long, weeping, rather brittle branches; the young leaves are reddish. Seed usually sub-
globose, with large, almost conferruminate, plano-convex cotyledons and a minute radicle.
As species, it and the next are near to C. caudata, Wall. Mr. Braine has lately intro-
duced a plant of it into the Kew Gardens. It flowers throughout autumn (October to

January), and the fruit succeeds the flowers very rapidly. 7 ricondyle pulchripes, White,
frequents this tree. -

4. CAMELLIA ASSIMILIS; frutex, ramulis glabris, foliis subsessilibus lanceolatis acuminatis
serratis glabris, floribus parvulis pendulis albis, sepalis sericeis obtusis, capsulis
glabris parvis rostratis.

Hab. in insulà Hong Kong, Sinarum, in Monte Victoria et Monte Gough.

x have — this species growing almost alongside of the last, and the general resem-
blance 1s very striking. Its smooth habit, shorter and wider leaves, and more especially
the difference of shape in the sepals, form the distinction. Its form is more stunted, and

PLANTS OF HONG KONG. 113

it grows amongst rocks and ravines. Its pretty pendulous flowers come out about
January.

Thea Bohea, Linn., is cultivated in Hong Kong, but is not indigenous to it. It fre-
quently forms borders to garden beds, just as we employ the Box. As a genus there
seems to be no good distinction from Camellia.

Genus Evrya, Thunb.

1, Eurya MACARTNEYI; dioica frutescens glabra, foliis majusculis coriaceis subellipticis
margine revolutis serrulatis, floribus majusculis; d staminibus 19-22; 2 stylis
distinctis revolutis, fructibus purpureis, circiter 14-spermis.

Hab. in insula Hong Kong, Sinarum, in sylvis rupibusque, Floret et fructus fert ab Augusto usque ad
Novembrem.

It is easily distinguished from Æ. Japonica, Thunb., by its larger (4 in. 2 lin. by 1 in.
7 lin.), more slightly serrated and revolutely margined leaves, their venation (grossly
reticulated), and the size of its flowers; also by the styles of the female flowers being free
to near their base. There are frequently black glands on the under part of the leaf. The
male flowers are 33—4 lines in diameter, 2-5 on each peduncle, and slightly fragrant. Sepals
orbicular, purplish, fimbriated, emarginate. Petals oblong-obovate, obtuse, white; patent
in the male and revolute in the female flowers; the latter only 14 to 13 line in diameter.
Male flowers without remains of an ovary. Anthers oblong, shortly apiculate. The petals
are united at base into a tube, like those of Symplocos. The ovary of the female is 3-celled,
each cell 5-10-ovuled; the ovules in place of being suspended are attached horizontally to
. the central axis.

It is a shrub 6 to 8 feet high, and as a species comes near to Æ. elliptica of Gardner.

This species has also been brought from China by Lord Macartney, and exists without
name in the Herbarium of the British Museum.

2. Eurya Japonica, Thunb.
Eurya Chinensis, R. Br.

These two species I find mixed up indiscriminately in my collection, and believe them
to be identical. Tt is a species subject to considerable variety, flowering profusely about
October. ;

The fruit is dark purple, and the size of a pea, 9-10, or, in poor specimens, fewer-
seeded, and crowned by the styles, which remain, even then, combined two-thirds of their
length; their revolute free portions eventually falling off.

-~ The male flowers are first greenish, then white, and have a nauseous smell; 2-3 together
on each peduncle, and 23—32 lines in diameter. Stamina 13-15 in one series. Ovary
of the male flowers abortive with remains of one style. Specimens grown on barren hills
are fewer-flowered than those growing in damp woods, and often smaller-leafed, and then
constitute Mr. Brown's E. Chinensis, collected by Abel. The fruit is pea-shaped, 3-celled
with about 3 seeds in each cell, attached at first to a placenta suspended from the apex
-of the axis. The berry is then succulent and nearly dry; finally, it becomes filled with

114 CAPTAIN CHAMPION ON THE TERNSTRŒMIACEOUS

purple mueilage, which nearly obliterates the cells. Seeds small, triquetrous, wrinkled.
Flowers and fruit, Oetober, November and December. The female flowers are one-third
less than the male flowers in size, and scentless. The pubescence or smoothness of the
ultimate branches I believe to be entirely local.

I obtained excellent specimens of male and female flowers and ripe fruit, all within
a few yards of each other, on December 6th, 1848.

Genus PENTAPHYLAX, Gardn. & Champ.

1. P. EURYOIDEs, Gardn. & Champ. (Tas. XII.)

This new genus is described by Dr. Gardner in Hooker’s ‘Journal of Botany,’ No. 8.
p. 244-246. The species grows to an undertree of great beauty when in flower, and is
exceedingly common in the Hong Kong woods. The flowers are small and white, and -
owing to those lowest on the branch expanding first, the pseudo-racemes when coming
into flower present a pyramidal form with the leaves at their extremity, and have a very
peculiar effect. The tree blossoms most profusely. The seed is dry, and its coating
membranaceous; the embryo conduplieate; its radicle terete and cotyledons plano-
elongate-cylindric. Flowers in summer and fruits in autumn. The definite 5 stamina,
anthers opening by terminal pores, and the fruit resembling that of a Gordonia on a small
scale (but with the embryo conduplicate), render it a very interesting genus.

Genus IXIONANTHES, Jack.

1. IXIONANTHES CHINENSIS ; subarborea, foliis petiolatis alternis glabris integris elongato-
ellipticis apice emarginatis reticulatis, corymbis longè pedicellatis axillaribus pluri-
floris dichotomis, staminibus 10 longissimis, capsulis supra-uncialibus. (Tag. XIII.)

Hab. in insulà Hong Kong, Sinarum, in sylvis.

A small tree with reddish brown bark; the leaves nearly 5 inches long by 1} inch
broad, much reticulated and chartaceous. The 5 cells of the ovary are 2-ovuled (pendu-
lously arranged by pairs), and in the fruit the seeds are naked, winged, and like those of
a Gordonia, to which genus its capsule approaches. The tree was originally referred to
Cedrelacee, but is now very properly classed with Ternstremiacee. Its sticky flowers —
and long filiform stamina are very peculiar. Several of the seeds which I sent to Kew |
have vegetated. : | |

Upon referring to Dr. Jack's description of the Sumatran species, Zrionanthes reticulata,
Jack, I feel some doubts as to the Hong Kong plant proving a new species. It differs in
the increased size of the leaves (5 in place of 3 inches long), and probably on comparison
will do so in some other particulars.

Genus GORDONIA, Ellis.
1. G. ANOMALA.

Polyspora azillaris, Sweet,

„ies highly ornamental tree is very common wild on the hills and in the woods of
ong Kong, and is much cultivated in that colony. Tts large, white, sleepy, Cistus-like

flowers are sweet-scented, and nearly 3 inches in diameter. Its capsule large and woody.
Flowers in autumn, in cold weather.

Genus ScHIMA, Reinw.
1. S. SUPERBA, Gardn. & Champ.

Already described in Hooker’s ‘Journal of Botany,’ No. 8. p.246. Flowers in May,
and fruits in October to December. Its bunches of large white flowers resemble Mesua at
a distance. The fruit is nearly 10 lines in diameter, subglobose and splits into 5 valves,
each containing 3 compressed reniform seeds. The embryo is curved, radicle terete, coty-
ledons large, and conforming to the shape of the seed.

A very rare tree in Hong Kong, except in the woods near the top of the slopes over
Little Hong Kong, where it grows abundantly.

Genus CLEYERA, Thunb.

1. CLEYERA FRAGRANS; arborea, tota glabra, ramulis di-tri-chotomis, foliis lanceolatis
margine integriusculis leviter revolutis coriaceis, ramulis floribundioribus, floribus
axillaribus pallidis fragrantibus fugacibus solitariis bibracteolatis, sepalis fimbriatis
petalisque glabris parvis, staminibus brevibus glabris; connectivo acuto, stylis 2 pro-
fundé divisis; stigmatibus reniformibus, fructibus globosis diametro subsemi-unci-

alibus.
Hab. in insula Hong Kong, Sinarum, in sylvis. FL Maio et Octobri. Fruct. Octobri et Novembri.

A small tree, with numerous sweet-smelling pale yellow flowers, which blow in the
morning and fall off before evening; the petals are combined into a ring, and are 21-21
lines in length. The leaves (about 3 inches long by 13 lines broad) are bright green
above, pale or rust-coloured beneath. Peduncles longish, reflexed, 1-flowered. Sepals 5,
oblong, fimbriately crenated. Bracteoles 2, ovate, fimbriated on the margin. Petals
gamopetalous, oblong-emarginate, smooth, margin uneven. Stamina very numerous,
filaments about a line long. Anthers bursting longitudinally ; connective small, acumi-
nated. Ovary conical, 2-celled; each cell with 2-8 collateral pendulous ovules. Style
profoundly cleft; stigmas reniform.

Fruit usually 5 lines in diameter, dry and finally hard, orange-brown with reddish
spots, globose, 2-celled, each cell 1-2-seeded. Seeds thickish, small (24 lines long), and
covered with a thin coating of oily scarlet mucilage, dying as in Biva. Testa hard and
bony, with a conduplicate embryo; radicle terete; cotyledons plano-cylindric. .

This may prove to be an Anneslea, Dr. Wallich’s genus; his species is described with
a 3-celled ovary. This tree constitutes much of the woods of Hong Kong.

2. CLEYERA DUBIA ; frutescens, tota glabra, foliis lanceolatis margine integriusculis leviter
revolutis coriaceis, floribus majoribus (84 lin. diametro) axillaribus pallidis bibrac-
teolatis, sepalis fimbriatis petalisque glabris, staminibus brevibus ; connectivo acuto,

I have doubts as to this being really different from the last. Their general resem-
blance is very striking, and the only specific differences I can perceive are, that here the
branchlets are more swollen, ash-coloured, and less compact, the flowers larger, nearly
scentless, and the petals less fugacious. The fruit and seeds are much larger; differences
which might also be effected by situation. The fruit is usually 3-celled, and the seeds |
43 lines long. The species of Oleyera are of very difficult discrimination. This ger
occasionally flowers when the young leaves are coming out.

XIV. On the Development of Ferns from their Spores. .
. By ARTHUR HENFR, Esq., FRS, F.L.S. Se.

Read June 15, and November 2 & 16, 1852.

THE remarkable discoveries published by Count Leszezyc-Suminski in 1848, together
with those to which they may be supposed to have led, in the allied families of the Crypto-
gamia, in the researches of Messrs. Hofmeister and Mettenius, are of a character to excite
the strongest interest among vegetable physiologists, from the important changes which
they appear to necessitate in our general views of the reproduction of plants. It is cer-
tain, moreover, that they equally deserve the attention of animal physiologists, since the
phenomena which have been described seem to point directly to a much closer relationship
between the characters of the sexual reproduction of plants and animals, than has of late
years been considered probable; for, while the facts which have been demonstrated in
reference to the mode of fertilization in flowering plants seemed to remove the possibility
of tracing any satisfactory analogy,—the pollen-tube differing so widely from the sperma-
tozoon,—a new set of conditions have been revealed in plants, which present the strongest
resemblance to those met with in the fertilization of animals. Still more, the remarkable
biological conditions known in the Animal Kingdom under the title of ‘ Alternations- of
Generations’ are found to occur in the Vegetable Kingdom in a much more definite
manner than was supposed, presenting all the distinctness which characterizes them in
animals, and by no means confined within the debateable territory in which they were at
first sought, namely, in the metamorphoses of the organs of single plants.

The observations of Suminski naturally attracted the attention of the more active vege-
table anatomists, and have already been repeated by several German botanists, whose
results, however, not only differ in many points from those of Suminski, but also among
themselves; and opinions are divided both as to the actuality of the existence of the most
important point of all, viz. the process of impregnation, and as to the period and circum-
. Stances of its occurrence. Thus, while Von Mercklin confirms Suminski’s statements in
regard to the act of impregnation taking place at an early period, Schacht and Wigand
deny it altogether; and, again, Hofmeister and Mettenius assert the fact of the impregna-
tion of a germ-cell by spermatozoids, but declare that Suminski mistook the structure of
the organs and the modus operandi of the phenomenon. |

Under these circumstances I believed myself performing a useful task in subjecting
the question to minute investigation. These researches were indeed commenced imme-
diately after the publication of Suminski’s treatise, but were left imperfect until the past
winter and the present spring, during which I have carefully repeated all my former
observations, and traced the development entirely through from the spore to the young
leafy plant, applying every available means to clear up the anatomical conditions in each

stage of the progress. The extreme delicacy of the young prothallium renders dissection
a matter of some difficulty, and, as in the embryotomy of flowering plants, the anatomist,
with all the skill acquired by practice, must be content to obtain decisive observations in
but a very small proportion of his preparations. |

The drawings which accompany this Memoir were nearly all made by means of the
camera lucida eye-piece, so that they represent preparations actually seen; the unimport-
ant details alone, such as the green colouring matters, &c., being given in a conventional
manner, except in a few separate figures devoted to the special illustration of these
points. |
The first part of the Memoir is devoted to an account of my own observations; to this
is added a critical examination of those of preceding authors; and, in conclusion, a few
remarks on the general bearing of the results upon vegetable physiology.

As some foreign vegetable anatomists have been inclined to lay great weight on the
quality of their microscopes, in discussing the points in dispute between different observers, -
it may be as well to state, that my investigations were made with one of Ross’s large
microscopes, with his l-inch, }-inch, i-inch and 4-inch objectives (about seven or eight
years old), and the drawings sketched in with the camera lucida eye-piece, after the pre-
parations had been fully observed with various other eye-pieces. The l-inch objective
sufficed for most purposes; the 4-inch was useful for the spermatozoids, but in regard to
anatomical points was chiefly used on account of the short focus, which is often advan-
tageous where the lines of cell-walls cross above one another. "The most important point,
however, is the clearness of the preparations observed, and on these I place my depend-

ence as to the accuracy of my statements, since there can be no doubt of my microscope
being quite equal to those of foreign investigators.

I. THE PROTHALLIUM.

The specimens which I investigated were obtained from the Chelsea and Regent’s Park
Botanic Gardens, consisting in a great measure of self-sown plants collected from the pots
of ferns growing in the stoves. Hence I am unable to give a very definite statement as
to the species of ferns on which I made my observations, and can only say that they were
chiefly species of Gymnogramma, Adiantum, Pteris and Asplenium; this is of the less
consequence, since the phenomena appeared to differ very little in the different specimens
in which specific distinctions were certainly known to exist.

Plants of Gymnogramma chrysophylla and of an unknown fern were obtained in the
earliest condition, for among the tufts of young prothallia placed beneath the simple mi-
eroscope for separation, I often found the burst capsule of the parent plant, with the

spores germinating within and growing out from it. Examination of these showed that

elongated in like manner and again divided, and sometimes this goes on until a row of
five or six cells is formed (figs. 3 & 4): when the first cell grows out into a long filament,
fewer cells are formed in the simple row. Chlorophyll granules show themselves, in-
creasing in quantity in the newly-formed parts. The first formation of radical fibres often
occurs in the earliest stages, consisting in the growth outward of the wall of one or more
of the cells of the filamentous prothallium into a slender tube, which attains a great
length, remaining narrow and uniform in diameter, and never having its cavity cut up by
partitions. All the roots met with on full-grown prothallia exhibit the same characters ;
they are tubular prolongations from the inferior walls of cells of the green, vegetating,
frondose expansion, and their tubular cavities are freely open into those of the cells from
which they arise. |

After a time the youngest cell of the growing prothallium becomes more expanded in
the transverse diameter, and after the next transverse subdivision of the cavity we find a
new mode of increase, namely, a division of the newest cell in a direction parallel to the
original direction of growth; by the frequent repetition of these two modes of extension
the prothallium gradually acquires a somewhat three-sided figure, with the angles rounded
off (figs. 5, 6 & 7). When it has attained a certain size a difference begins to present itself
in the degree of expansion of the new cells continually formed by subdivision; those in
the middle of the front border (that directly opposite to the original point of growth)
remain small and are greatly surpassed in size by those at the sides and at the two ante-
rior angles, so that the latter advance forward as rounded lobes, leaving a notch or exca-
vation in the middle, giving the entire prothallium the form which in leaves, &c. is termed
obcordate (fig. 9). In the meantime great quantities of radical hairs are developed from
the lower faces of the cells in the neighbourhood of the obtuse apex of the heart-shaped
frond, that is, about the posterior part of the prothallium, which generally exhibits a very
ill-defined margin, as the cells formed at first often decay away and disappear, leaving a
ragged edge (figs. 9 & 10).

While the ga pas which varies a good deal in different species in the lateral p
pansion of the two lobes, is becoming perfected, the middle and posterior region of the
prothallium, near where the roots arise, begins to display a new mode of growth. Up to
this time the entire prothallium consists of a single flat layer of cells, in which state the
lateral lobes and the anterior border persist, but in the central and posterior p the
cells now become divided by horizontal walls, so as to give the prothallium a thickness
of two, three, or more cells in the vertical section (figs. 62 & 67). The thickened portion
forms a rounded cushion-like projection from the inferior face of the prothaliewn (fig. 51),
while the upper surface remains flat or is even slightly depressed in the region over the

is contained in a membranous vesicle, and that these vesicles are increased m number by
a process of subdivision like that of cells. I have met with appearances which I cannot
explain in any other way, but shall be content wath a mere indication here, to avoid
digressing from the immediate subject of this Memoir. I believe that I have seen the
enveloping membrane enclosing a green fluid (fig. 15) ; moreover, the development of two
or more starch-granules inside those vesicles, so as gradually to displace the chlorophyll ;
but as the vesicles are only about 3555th or 15-555th of an inch in diameter, much careful
examination is requisite before a safe decision can be arrived at.

In some cells I have seen a small colourless and formless accumulation of mucilage
upon the side wall, among the chlorophyll globules. It is possible that this may have
been a nucleus. I also found a large clear and circular vesicle in one of the cells of an
old barren prothallium ; this had all the appearance of a nucleus, excepting that it was so
exceedingly transparent. In the vegetative cells generally I saw no trace of nuclei.

The cells of the older posterior part of the prothallium contain but little chlorophyll,
and like the root-filaments, are filled with colourless, slightly granular mucilaginous fluid ;
and they often appear stained with brown patches, arising from the partial decay of the
walls. In all cases the death of the cell-membrane is followed by a brown colouring of
the dead part. |

Such is the normal history of a prothallium, so far as its vegetation is concerned (for
the reproductive structures, left out of view in the preceding description, are in part deve-
loped at a very early period). -If the regular development of a leafy stem takes place, a
term is naturally set to the existence of the prothallium, which quickly decays away as
the young stem grows up. But if the prothallium remains barren, if none of the arche-
gonia become fertilized, its vegetative existence may be continued for a long time. The
lateral lobes grow much larger, their borders become curved and sinuous, or variously
convoluted; new lobes sometimes grow out from the cushion-like thickening in the
middle; and, finally, individual
development exhibited by the spore-cell in the original germination, so as to produce new

prothallia (by a process of budding), which become detached from the parent (fig. 12).

The progeny of * proliferous ' prothallia exhibit antheridia, but I have never seen arche-
Jona upon them. In other

respects they are exact repetitions of the parent structure.

course of development in a comparatively short space of time, we have them coexistent in
every condition of their development in prothallia which are fully formed. When anthe-
ridia appear on very young prothallia, composed of a single row of cells, or at most of a
double row in the upper part, they present themselves as productions from the margins,
the outer side of one of the cells giving origin to each antheridium. But as soon as the
prothallium has acquired anything like a flattened form, by the transverse expansion of
the anterior end, the antheridia are formed almost exclusively upon the inferior surface,
that surface in contact with the soil upon which the plant grows. They appear first upon
the older cells of the central region, and gradually spread forward as the prothallium
grows, but appear seldom to extend beyond a certain distance from the centre, occurring
in greatest number about the central cushion-like protuberance above described.

It has already been stated that they occur upon the progeny of the proliferous barren
prothallia; in some cases I have found these branching at their edges and bearing anthe-
ridia in a very abnormal position, at the ends of projecting cellular processes (figs. 27-32);
this, however, afforded great facility for observing the internal structure of these organs,
and checking the results obtained by observations upon sections.

The first sign of the production of an antheridiwm consists in the elevation of a globular
protuberance from the lower, free surface (or in the young prothallia from a lateral
surface), forming at first a kind of globular pouch (fig. 17), in which are seen at first a
few chlorophyll globules, which afterwards vanish and give place to a collection of light
yellowish, mucilaginous contents, slightly granular. A septum is soon formed, shutting
off this budding cell from that which gives origin to it, and as it becomes elongated
another cross septum often appears, a little higher up (figs. 21 & 29, &e.), so that the
structure then consists of a basal cell forming a peduncle,'as it were, for the proper anthe-
ridial structure. This occurs most distinctly in marginal antheridia (figs. 27-32).

The antheridial structure, at first consisting of a simple cell, exhibits a considerable
eollection of protoplasm occupying the greater part of its cavity ; but this portion soon
becomes defined by a cireular wall, which makes its appearance simultaneously all round
the central eontents, converting the simple cell into a compound organ, Ang of a
central cell surrounded by an annular cell; while a horizontal septum is formed above
and at right angles to this, eutting off a new cell, convex above and flat at the surface, in

its cavity. The same takes place upwards and downwards, and thus the antheridium,
when examined in this state, seems to consist merely of one large cell (figs. 21, 22 & 26),
with rather thick walls consisting of a double membrane (figs. 24, 25). j

While in this expanded condition the entire structure increases in size, and the contents
of the central cell become more granular. After a time faint lines can be detected run-
ning through the protoplasm (fig. 21), and these soon display themselves more clearly as
the boundaries of square isolated masses of the protoplasm (figs. 22 & 25), the nascent
sperm-cells. ‘Around each of the little masses thus isolated a membrane is formed. -It
was impossible to ascertain whether the parent-cell was first divided into a number of
square partitions, by cross walls, thus producing * special parent-cells," for the sperm-cells,
like those formed in the development of pollen-grains, the original partitions subsequently
becoming dissolved to set free the cells thus originally connected together; or, whether
the protoplasm was simply entirely broken up into a number of isolated portions, each of
which secreted a membrane and thus formed a free cell; but I incline to believe that the
latter was the fact, and that the same oceurs in the completely similar case of the produc-
tion of a number of closely packed endosperm-cells, in the embryo-sac of many Phanero-
gamia, as in the Cruciferæ and Scrophulariaceæ*, However this may be, the result is the.
production of a large number of free cellules, filled with mucilaginous protoplasm (figs. 26,
34), of a light yellowish colour, becoming gradually more and more granular. As these
cellules, at first squarish, enlarge, they become spherical, and by their expansion distend
the parent-cell and disguise the existence of the annular coll surrounding it. Their num-
ber, in well-developed antheridia, seems to be between thirty and forty, probably never
exceeding the latter number. !

The free cellules, the sperm-cells, become more and more opake and granular, and after
o vn spisal lines may be detected in them, while still within the parent-cell in the
antheridium (figs. 35 & 36). At this time the antheridia may be burst very easily by pres-
sure (fig. 36), ani the sperm-cells which escape can be observed in all stages of develop-
ment, until a spiral fibre can be clearly seen, coiled up in the interior. Specimens lying
in water, under the microscope, now frequently exhibit a movement of the contents of the
sperm-cells, they swell up, and the spiral lines are seen to change their position. Very
often the bursting of the sperm-cells takes place within the antheridium, and the sperma-

en entire from the antheridium. This occurs by the splitting of the line of junction

their former position so as to render the existence of the enveloping cell or cells very
evident. After the whole of the contents have been discharged, the walls of the parent-
cell acquire a deep brown colour, presenting a peculiar appearance and making the anato-
mical structure of the antheridium very clear (figs. 48,49). The lower faces of full-grown
prothallia exhibit, when moderately magnified, a great number of circular bodies with
brown roundish or squarish central patches; these are effete antheridia, with the brown
walls of their cavities showing through the orifice at the summit (see figs. 19 & 50).

We have next to consider the appearance of the spermatozoids, produced by the sperm-
cells. These cells, as stated already, generally emerge entire from the antheridium, the
spiral fibre being visible, in movement, in their interior. After a variable time, according
to the stage of development of the spermatozoid, it breaks through the wall of the sperm-
cell, and if perfect, escapes entirely from it. "When perfect it appears to consist of a flat-
tened band, curled spirally into about three and a half coils, bearing all along the outer
edge, cilia of considerable length, vibrating with great rapidity ; so much so, indeed, that
they appear only like a fringe of light while the spermatozoid is in active motion (fig. 40).
The filament when in the condition of the lowest specimen in the group (fig. 40) mea-
sures about j555th of an inch in length, as coiled up; the diameter of the widest coil,
about equal to that of the sperm-cell, is usually about 4955th of an inch. I never saw one
uncoiled and flaccid but once; this measured about 3,3;5ths of an inch in length (fig. 42 a).
The motion consists of a rapid rotation around its axis, which, from the spiral form, causes
a motion of great velocity, forwards, in the water. The motion does not seem to follow
any fixed rules; the spermatozoids dart here and there, turn aside or backwards, or alter-
nately to the right and left in their course onward, so as to preclude the possibility of laying
down any formula or law for it. If they come in contact by the smaller extremity with
any fixed body, they often adhere by this point and then revolve around their axes without
advancing. By degrees the motion becomes slackened and the rotation is lost, merely a
kind of vibratory motion remains, and this at length ceases; but the spermatozoids seem
to undergo dissolution during this time, and when they come to rest often appear as
shapeless masses. By applying iodine the movement of the most active can ‚be stopped
instantaneously, and in this way a tolerably clear view of the structure is obtained.
Under these circumstances the cilia may be seen pretty clearly (fig. 41); the flattened
band exhibits minute granules adhering to it, and is seen to have a little rounded head,
from which the coils run back, increasing successively in diameter, so as to give a conical
form to the outline of the whole, as seen at the side.

Such, so far as I can make it out, is the character of a perfect spermatozoid. But these
bodies acquire the capability of motion, of whatever nature this may be, before they are

: : i t ts which different observers
perfectly developed, and hence, I imagine, the different accoun
have given of them. It seemed to me that when they had not acquired their full develop-
ment, the fibres could not unroll into the true form when they emerged from the eperm-
cell; they thus appeared to present fewer coils, often ‘only one and a half, the latter of
very large diameter; in other cases they looked like minute shells of Gasteropodous Mol-
lusks. In fig. 46 I have given representations of several of these forms, and it should be
observed that these imperfect forms exhibited a greater quantity of adherent granules, and

124 MR. HENFREY ON THE DEVELOPMENT

a less definite outline than the others. Finally, some appeared unable to extricate them-
selves from the sperm-cell, and carried this along attached to the posterior extremity
(fig. 44). This vesicle attached to the spermatozoid has been described by some observers
as formed by the swelling of the extremity of the filament after its exit from the sperm-
cells, therefore as constituting an integral part of the structure of the spermatozoid ; but
I believe this to be an error.

In one case I saw an appearance which seemed to indicate the existence of a hair-like
produetion of the posterior extremity of the spermatozoid, like that figured by Hofmeister.
A spermatozoid moving rapidly forwards in the water dragged after it, at a little distance,
a small mass of mucilage (fig. 425); the bond of connection was invisible, and therefore,
most probably, must have consisted of a capillary process. I never saw any hair-like tail
in specimens suddenly paralysed by iodine, but it may have escaped notice from its
tenuity; on the other hand, it may possibly be only found in the most perfect state of the
X spermatozoid, and since these are examined under artificial conditions, often causing the
rupture of the antheridia before their contents are mature, the most perfect condition may
only be met with occasionally.

III. THE ARCHEGONIUM.

In the description of the development of the prothallium, it has been stated that a
thickened, cushion-like mass is formed in the central region, by the time the general form
has become complete (fig. 51). "This central mass is composed of several layers of cells,
and, projecting from the general surface, does not reach quite to the inner extremity of the
anterior notch of the prothallium, so that an inclined surface is produced looking somewhat —
forwards toward the notch (fig. 52). Upon this arise the archegonia, which are variable
in number, seldom however exceeding six or eight.

The earliest rudiment of the archegonium is the embryo-sac, as it may be termed, con-
sisting of one of the cells of the thickened cushion, separated by a single cell from the
(inferior) surface of the prothallium (figs. 54—57 a). A cell, destined to become an embryo-
sac; is found surrounded by a circle of cells of smaller size than those of the surrounding
tissue, and formed by the production of walls in the cells immediately bordering the
embryo-sac, tangental to the circumference of the latter, which thus becomes defined by a
wall of small cells surrounding it (figs. 55, 57 b). Cell-division also takes place in the
cells beneath the embryo-sac, and these multiply so as to form a collection of condensed
tissue enclosing the embryo-sac at the sides and below (figs. 66, 67 6), visible through the
cells of the surface of the prothallium (figs. 54, 56) before the external structure is formed.
The commencement of the development of this consists in the enlargement of the cell sepa-
ve the embryo-sac from the surface, and its division into two cells by an inclined wall,

e larger of these being again divided by another partition at right angles to the former,

overlaps «1 and «2; another division of c leaves c 1 and ¢2 over a1 and «a2, and carries
up d to form d1 and d2, above b1 and b 2, until the papilla reaches its full height, and
appears composed of tiers of four quadrant-shaped cells, the first tier consisting of al and
a2, bl and 52 of the series; the next tier of c1 and c 2, dl and d2, &c. (figs. 58-61).

In the meantime, the embryo-sac at the base, which very early appeared filled with
opakish protoplasm, comes to exhibit a central globular body (figs. 56, 57 c), which in all
. probability is an isolated mass of protoplasm, destined to secrete a membrane around it,
and to form the germinal vesicle, just as occurs in the embryo-sae of Phanerogamia (for
example in Orchis). The next peculiarity is the appearance of a clavate cavity running
up the centre, between the convergent inner angles of the four series of cells of the papilla,
forming a canal evidently communicating, through a constricted neck, with the embryo-sac
(figs. 62-70). In this canal is observed a slender clavate filament of slightly granular
mucilage (fig. 70) running down into a point in the embryo-sac below, where I believe it
is in contact with the germinal vesicle: I imagine this to be a portion of the protoplasm
of the embryo-sac which has been protruded up into the intercellular canal of the papilla,
after the absorption of the wall of the embryo-sac, where it at first closed the bottom of
the canal at the constricted neck. After a time the canal becomes opened to the external
medium, and then the clavate filament is often seen hanging out from the open mouth
(figs. 63-66); it is generally double (figs. 63, 64) at the upper end, which I cannot explain.
It appeared firmly attached in the canal, and bore the movements of the preparation, by
pressing and sliding over the covering glass, without becoming detached from the papilla.
. It is at this stage of development that I believe the impregnation to take place; but
before proceeding to speak of this part of the subject, I may conclude the description of
the archegonia, by stating that the greater part of them are abortive; very rarely more
than one being fertilized on a prothallium, and very often none. When thus abortive the
cellular papillæ continue growing to some extent, the central canal becomes widely opened,
often into a large funnel-shaped orifice, and the walls of the intercellular canal and the
embryo-sac acquire the same deep brown colour as the interior of the effete antheridia
(figs. 72-74). |

IV. DEVELOPMENT OF THE EMBRYO.

My opinion with regard to the fertilization is, that the operation is effected by the con-
‘tact of one or more spermatozoids with the mucilaginous filament contained in or hanging
from the mouth of the canal of the archegonium. I have seen the spermatozoids swim-
ming in numbers around the mouth of the archegonia, but never detected one inside, and
I do not see any good reason for supposing such a process necessary. The pollen-tube of
flowering plants only comes in contact with the outside of the embryo-sac, and the in-
fluence is sometimes communicated through a long suspensor ; and there does ge "ES. to
be any sufficient objection to the supposition, that the contact of the spermatozoid with the
filament of mucilage which lies in the canal of the archegoniwm, suffices to convey the

VOL. XXI. | x

126 . MR. HENFREY ON THE DEVELOPMENT

necessary stimulus. I imagine this stimulus resides in the mucilaginous fluid in which -
the spermatozoid is bathed in the sperm-cell, and which, adhering to this, is conveyed to
the mucilage (protoplasm) of the germinal vesicle, just as the contents of the pollen-grain
become combined with the protoplasm of the germinal vesicle in flowering plants. The
nature of the process is clearly a problem beyond the reach of science, but it seems to be
a necessary induction, from the facts in the Phanerogamia, that the phenomena result
there from the material union of two fluids, and I hence conclude that this is the case
here. The comparatively few cases of successful impregnation among these prothallia, so
many of which prove sterile, may perhaps be accounted for by the peculiar conjunction of
circumstances required to bring a sufficient amount of the fertilizing fluid, by means of
the spermatozoids, to the germinal vesicle, at the precise epoch required.

Some doubt has been thrown upon the possibility of the impregnation of the archegonia —
by means of the spermatozoids, on the ground that the free movement of the latter in the
water, beneath the microscope, is an abnormal condition. I attach no weight to these
objections, for the occurrence of numerous empty antheridia, on moderately developed
prothallia, proves that their dehiscence is a natural process, and if the moisture which
always exists upon the under surface of the prothallia is insufficient to allow such a wide
and free course to the spermatozoids as they find in the water on the glass slider beneath
the microscope, we see a compensation for the obstacles in the way of the conjunction in
the large number of antheridia produced, and this not at one time only, but throughout
the whole growth of the prothallium. Again, there is evidence that the process is not
easily and constantly completed, in the fact of so many prothallia remaining sterile, and
in the provision of several archegonia upon each, while in normal cases only one produces
an embryo.

Arguments have been urged against the entrance of the spermatozoids into the archego-
nium, from the consideration that the mouth of the canal is directed downwards, and the
spermatozoid would consequently have to work its way upwards, contrary to the attraction
of gravity ; and further, from the fact that the apex of the archegoniwm is usually directed

forwards towards the notch of the prothalliwm, while the antheridia occur principally about

the posterior part. If we imagine the contact of the spermatozoids with the mucilaginous

matter protruding from the mouth of the canal to suffice for the imp ET
tb
understood, however, or the impregnation (it being

sie that this happens under such circumstances that the spermatozoid
is from the antheridium, and the mucilage of the canal of the archegoniwm has not
yet become coagulated by exposure), this difficulty is done away.

The first result of the impregnation,—that is to say, the first step of development of the

embryo, which I believe to be the consequence of such an operation,—as seen by means

of vertical sections of the prothallium, consists of subdivision of the germinal or embryonal

in the embryo-sac. "The succeeding stages of growth of this new cellular body, the embryo,
consist of a gradual multiplication of the cells by division, and expansion of the new struc-
ture, until at length the rudiments of a radicle and the first leaf become visible as projec-
tions from the surface, resulting from the more rapid increase of the cells in the situation
where they are found (figs. 76—79).
-Tn the ulterior development of the embryo the radicle appears to be arrested in its deve-

lopment, and to remain as a cellular mass (fig. 80a) within the cavity of the prothallium,
until it disappears with the latter by decay. The first leaf unfolds upwards and forwards
(fig. 80 2) towards the notch of the prothallium, and the first adventitious root (fig. 80 c)
breaks through at the base of this towards the posterior border of the prothallium, exhi-
biting a coleorhize like that of the Monocotyledons. The second leaf arises near the axil
of the first, one-third of the circumference of the nascent stem to the side; the third leaf
arises one-third to the side of the second, so that the three leaves form a circle, in which
they stand at equal distances, and the fourth leaf arises over the first (Gymnogramma
chrysophylla?). They are of very simple structure, consisting of cellular plates with twice-
forked rudimentary nervures, and they are accompanied by very elegant ramenta at the
bases of the little petioles (figs. 81-83).

I have not followed the development beyond the formation of the fourth leaf (fig. 83),
by which epoch the prothallium has generally decayed away from the base of the young

stem.
V. CRITICISM OF PREVIOUS OBSERVATIONS.

The first account of any of the peculiar structures above described was published in
1844 by Nägeli*, in a memoir entitled “Moving Spiral Filaments (spermatic filaments) in
Ferns,” wherein he announced the existence of the bodies now called antheridia, but mis-
taking the archegonia for modified forms of the antheridia, he was led away from a minute
investigation of them. If he had followed the development of the prothallia further, he
would have detected the relations of the nascent embryo, which would probably have put
him on the right track. As it was, the remarkable discovery of the moving spiral fila-
ments, or spermatozoids, occupied all his attention, and caused him to fall into error in
certain important respects; for example, in fig. 11 of his plate, he has represented what
is undoubtedly an archegonium, filled with cellules (sperm-cells), which, he states, emerged
from it as from the antheridia: this is undoubtedly incorrect.

With regard to the spermatozoids his description is imperfect, the only indication of the
existence of cilia being a statement that he occasionally saw a long filiform appendage,
like that represented by Meyen in the spermatozoids of Chara. On the other hand, the
mathematical definition of the movements of the spermatozoids is surely misplaced, since
nothin be more arbi or irregular than their course.

inquiring spirit of this author that we owe the first step of the investigations which have
thrown so much light upon the reproduction of the higher Cryptogamia. eai

of the important investigations of Count Suminski, which were first made known in
the * Bulletin’ of the Berlin Academy, and by a note from Dr. J. Münter in the * Bota-
nische Zeitung,’ but were given in a complete form in a separate treatise by the author
in 1848*. |

These investigations, which form the basis of the subject before us, from the capital fact
of the discovery of the archegonia and of the development of the embryo from one of these,
present a curious mixture of industrious observation and preconceived theories. It is an
invidious task to criticise an essay which has so greatly advanced our knowledge of the
subject, but it is an unavoidable one. The great fault of the essay is the free exercise of
the imagination in cases where the delicacy of the structures renders the objects exceed-
ingly difficult to make out clearly. I feel warranted in making this assertion by the fact
that my own microscope must be equal if not superior to that used by Count Suminski,
since I have seen, with the greatest clearness, points which he missed, where good defi-
nition of the microscope was all that was requisite, and on the other hand, I can trace
actual invention in cases where bad definition of the object would leave points obscure
which I saw distinctly. Moreover, his figures display appearances which I neither saw
nor can conceive the possibility of seeing with the distinctness represented in his drawings,
while some of these bear patent evidence of a faulty interpretation of tolerably clear con-
ditions. |

Such assertions of course require evidence, and it is desirable that this should not rest

upon counter-statements alone, but should furnish some explanation of the probable causes
of the errors stated to exist.

cellules, shown in Suminski’s figures (pl. 2. figs. 12-16), are, like those of the antheridia,
derived rather from the imagination than from fact.

But the most important errors occur in the account of the development of the arche-
gonia. The earliest stage, as seen by looking directly upon the (under) surface of the pro-
thallium, was completely misconceived by Suminski. He overlooked the cell, forming
part of the general surface of the prothallium and becoming the parent-cell of the papilla,
which, from the first, lies between the embryo-sac and the external medium; so that he
imagined the embryo-sac to be open and capable of admitting spermatozoids into its cavity.
I examined this point most carefully, and am convinced that he was in error. Any one
who looks at his figs. 1 and 2 of plate 3. will see that there exists no trace in them of a
cell or cells from which the papilla (seen from above in fig. 3 of his 3rd plate) could arise,
for the supposed orifice is bounded by seven cells, and if the papilla sprang from these it
would consist of seven vertical series instead of four. The fact is, that his fig. 1 of pl. 3,
stated to be from a dissection, merely shows what is seen in looking upon the under sur-
face of the prothalliwm, without dissection ; but it represents the object focused down to
the globule in the embryo-sac, as in my fig. 57, so that the membranes of the cells occu-
pying the space supposed to be an orifice and forming part of the continuous surface of
the prothallium (my fig. 56) are not seen. Fig. 3 of Suminski's 3rd plate shows a sub-
sequent stage, where the papilla, composed of four rows of cells, is already developed; he
has missed the gradual production of this from the cell occupying the situation of the
imaginary orifice. i

This clearly takes away all ground from his hypothesis of the impregnation resulting from
the entrance of spermatozoids into the embryo-sac before the development of the papilla of
the archegonium, and moreover proves that the bodies contained in the closed canal of this
organ (shown in his figures, pl. 3. figs. 4-7) could not be altered spermatozoids. It will
be remembered that I have explained these appearances in a totally different +

With regard to the phenomena of the development of the germinal vesicle in the em-
bryo-sac, I think it is scarcely possible to obtain such clear views of the young structures
as Suminski has given, and I could only approximate to them by sections through the
prothallia, while from his figures we are led to suppose that he saw them through the
enveloping tissues, which are far too thick to allow such clear definition, especially since
their contents soon become coagulated by the injury the preparation suffers in water and
under pressure. All that Suminski states, therefore, respecting the development of a

It is unnecessary to enter into any other points. It is seen that the only matter in
which I am agreed with Suminski is the import of the organs and the existence of a sexual
conjunction; in all the details of the processes I am at variance with him. Nothing,
however, can take from him the credit of having discovered the archegonia and their im-
port, one of the most important discoveries in physiological botany of modern times;
since it has led to results revolutionizing the whole theory of the reproduction of plants,
and opened out a totally new sphere of inquiry into the laws and relations of vege-
table life.

The next contribution to the subject to which such a lively interest had been attracted,
was a paper by Dr. Wigand *, giving a detailed account of a series of critical observations
on the question, and dedueing conclusions directly opposed to those of Suminski. Dr. Wi-
gand's observations do not seem to have been complete and thorough-going, for he also
describes the perfect antheridium as a single cell, and appears to have confounded the
complex structure seen in the effete antheridia with that of the archegonia (p. 23 loc. cit.).
His description of the development of the sperm-cells within the antheridia is nearer the
truth; but while right in rejecting the ideas of Nägeli and Suminski, that these originate
by free cell-formation around a nucleus, he fell into a different error in supposing that the
cellules were not in contact at first, but were formed in groups around isolated portions of
the cell-contents. His description of the spermatozoids is pretty accurate, but the differ-
e he describes appear to me to indicate different stages of development, and not to

epend upon the specific differences of the specimens examined. He overlooked the
earliest stages of the growth of the archegonium, and especially the existence of the

Lastly, it is unnecessary to criticise Dr. Wigand’s views as to the origin of the embryo,
or, as he calls it, the “bud” of the new plant, since he admits that he did not trace
the earlier stages of its development, and seems never to have investigated it by sec-
tions, so as to see the relations with the embryo-sac. His opinion was that no relations
did exist. :

Shortly after the appearance of Dr. Wigand's memoir, M. G. Thuret* published an
account of the antheridia and their contents, the particulars of which agree pretty closely
with those I have given. He states the structure of the antheridium to be less simple than
Suminski and Wigand had described it, consisting of a parent-cell of the sperm-cells sur-
rounded by an annular cell, but not by a collection of flattened cells such as Schacht and
Hofmeister describe. He does not enter minutely into the development of the spermato-
zoids, but describes them accurately, excepting, as I believe, in reference to the hyaline
vesicle, which he says they ordinarily drag about with them ; this vesicle, which in a later
paper t he states to be in all probability a product of the spermatozoid, I consider to be
the parent sperm-cell, from which the spermatozoid has not completely extricated itself,
and I did not find it in the majority of cases.

In the same year M. Hofmeister published a brief preliminary summary of his obser-
vations on the reproduction of the Cryptogamiat, wherein he arrived at conclusions which
approximate pretty closely to those I have given, but to which I shall refer more par-
tieularly presently, in analysing the portion referring to the Ferns of his great work on
this subject.

The next important contribution was an elaborate paper by M. Schacht$. In exami-
ning this it is unnecessary to repeat the particulars in which he agrees with ‚all other
authors, and I shall therefore confine myself to the debated points.

In reference to the antheridia, where he differs from Thuret and myself, he states that
the envelope of the parent-cell of the sperm-cells is composed of a number of cells, the
annular cell which I have described being supposed to be divided by four perpendicular
walls, so as to form four cells constituting a quadrangular boundary to the central cell.
Where a horizontal septum exists, the envelope would consist of eight cells forming two
circles of four. This view I hold to be incorrect, for I never could see the numerous boun-
dary lines which such a structure would exhibit, in the hundreds of antheridia which I
have examined. He also supposes that the sperm-cells originate by free cell-formation in
the central cell, which I must distinctly deny. E

Schacht describes the spermatozoids as having four and a half or five turns in the
spiral coil; I believe three to four is the utmost: moreover, he regards the widest con-
volution as the anterior, a view which I cannot explain, and he states that this passes —
a vesicular structure which swells up in water (as described by Thuret); this I consider

the sperm-cell, still adherent to the spermatozoid.

E 132 MR. HENFREY ON THE DEVELOPMENT

. The archegonia are stated by him to be found exclusively upon the thickened part of
the prothallium (in opposition to Wigand), as I have described them. He further says
that the earlier stages of development are difficult to make out, but he believes the
papilla originates by the subdivision of one of the cells of the prothallium into four by
vertical septa crossing each other, these growing out into a conical body; the canal, and
the cavity at the base (the embryo-sac) are supposed to originate as intercellular cavities,
by the separation of the cells bordering them. The canal is closed at first and open after-
wards. It is evident from these statements that the earlier conditions of the embryo-sac
were overlooked. The mucilaginous filaments in the canal of the archegonium were seen
and figured by Schacht, who correctly asserts that they are not decaying spermatozoids,
as supposed by Suminski. He states that the embryo originates in the cavity at the base
of the archegonium (the embryo-sac); but he seems to suppose it to be merely a vegetative
growth, as is evident from the concluding paragraph of his memoir :—

“Since the ‘germ-organ’ (archegonium) is not open originally, but closed, the fact of
its opening subsequently, when it has become surrounded by a high cellular wall, together
with the circumstance that the direction of the orifice is downwards, render it scarcely
conceivable how * spiral-filaments’ could make their way into it; moreover, in spite of
the utmost patience and care, I could never observe a ‘ spiral-filament ’ inside the ‘ germ-
organ,’ still less the conversion of one of them into the * germ ' (embryo). Consequently .
the impregnation of the Ferns, as described by Count Leszezyc-Suminski, is more than
improbable, and thus the inclusion of the Ferns among the Phanerogamia is by no means
Justified.”

In these conclusions we see that the bias given by the adherence to Schleiden’s doctrine
of the origin of the embryo in the Phanerogamia, of which Schacht is one of the leading
defenders, has prevented his entertaining the idea of the spermatozoids exerting simply a
fertilizing influence. All his argument is against the conversion of one of them into an
embryo, so that the hypothesis I have adopted is not touched by the above statement, and
it is unnecessary to add further remarks.

OF FERNS FROM THEIR SPORES. 133

In the same year appeared an essay on this subject by Dr. Von Mercklin*, which I
have not seen, but I am able to state the principal points in it, from the circumstance of
his having published an abstract of them in the ‘ Linnæa t, in answer to Schacht's criti-
cism of Suminski’s views.

Von Mercklin states that the antheridia appeared to him to consist of never more than
five cells; sometimes they appeared still more simple, but he gives no details in his
abstract. Of the spermatozoids he says that the figures given by Thuret and Wigand
agree best with his observations, those of Suminski worst, but he regards the large vesicle
figured by Schacht at the extremity of the widest coil, as the adherent sperm-cell. He
also considers the broad convolution to be the posterior, since the spermatozoid always
advances with the narrow end foremost; in this his statements accord with my own
observations.

In reference to the archegonia, he truly says that Schacht overlooked the earliest stages,
and he asserts that although he is not positive concerning all cases, he has distinctly
seen an orifice into the cavity of the archegonium (the intercellular cavity, as he and
Schacht consider it, but the embryo-sac of my description) in the situation of the cell from
which the papilla grows up, pretty much therefore what Suminski described. Moreover,
he states that he has seen spermatozoids enter this. But he does not appear to attribute
importance to any particular: epoch for the contact of the spermatozoid with the embryonal
vesicle, which lies in the cavity (embryo-sac), for he states that of the three times he
witnessed this phenomenon, in the course of an entire year’s observation of the subject,
the spermatozoids twice entered the nascent organ, as described by Suminski, and in the
. other case entered the open canal of a fully developed archegonium, to reach the “ germ-
cell” (embryonal vesicle). He states his belief that the mucilaginous filaments seen by
Schacht, Mettenius, &c., in the canal, are really altered spermatozoids, and he concludes
with the following assumptions :—

* 1. The spermatozoids do regularly enter into the archegonia; and, 2. Probably con-
tribute to the origin or the development of the first.*germ-frond. How this takes place
I know not, and the details concerning it, given by Count Suminski, remain for the pre-
sent unconfirmed.” and

The last observations to which I have to refer are those contained in M. W. Hofmeister's
recent work tf, forming part of an elaborate series of investigations on the reproduction of
the higher Cryptogamous plants. :

This adie a describes the antheridium as a more complex structure than I
and Thuret imagine it to be, since he believes the walls enveloping the central parent-cell
of the sperm-cells to consist of four or eight cells, constituting a quadrangular boundary,
instead of being simply one or two annular cells. He further states that he found, on sung
prothallia produced by budding from old barren and proliferous prothallia, antheridia of the

simple structure described by Suminski and Wigand, consisting of a simple cell; this
statement is quite contrary to my observations; I frequently examined antheridia in all
stages in such prothallia, and they differed from the normal form only, in certain cases,
by being supported on elongated pedicels produced by an unusual growth of their basal
cells (fig. 50). With regard to the mode of development of the sperm-cells, Hofmeister de-
scribes, as I have done, the gradual subdivision of the mucilaginous contents of the parent-
cell into numerous cubical portions, each of which becomes clothed with a membrane and
produces a spermatozoid within it. His description of the spermatozoids differs but little
_ from mine; he asserts, however, the regular existence of a long and very slender hair-like
process at the hinder extremity, which I have only seen an indication of in one case.

In his account of the development of the archegonium he differs considerably both from
Mettenius and myself, although the final results are the same. According to him, the
papillar process is formed before the basal cavity (the embryo-sac), by the growth out-
wards and subdivision of one of the superficial cells of the cushion-like thickening of the
prothallium. He describes the formation of the archegonium in the following manner:
the superficial cell which gives origin to it becomes divided by an oblique wall into an
upper and a lower cell, the upper and larger is again divided by an oblique wall inclined
in the opposite direction, and this is repeated five or six times; this would result in the
formation of a papilla composed of two parallel rows of cells slightly overlapping alter-
nately as they rise; but as they are developed each is divided into two by a perpendicular
radial wall, so that the papilla consists of four conjoined vertical piles of cells. In the
next place, either all or only the lowest of the cells of one of the vertical rows become
divided into two by a tangental wall; so that, in the first case, a central row of cells is _
formed, running up the centre, or, in the second case, the extra cell is only formed at the
bottom. This lowest cell, which is the embryo-sac, becomes enlarged rapidly ; the cells of
the prothallium immediately surrounding it become divided by septa so as to form a kind
of epithelial layer around it. During this growth the canal is formed up the centre of
the papilla, when the fifth row of cells exists by the solution of all butthe bottom one, and
when this extra cell is formed only at the bottom, by the separation of the contiguous
Pen a of = four rows, so as to form an intercellular passage. The greater part of

subdivided, so as to form a globular mass of cells, in which the prominences indicating the
radicle and leaf soon make their appearance.

He never saw the actual entrance of the spermatozoid into the archegonium.

VI. CONCLUSIONS.

In summing up all these statements it becomes evident that the balance of evidence is
in favour of the existence of sexual organs, and of a process of impregnation, giving rise
to a new individual, as asserted by Suminski, although under conditions somewhat different
from those described by that author. Only two of the observers who have repeated his
investigations throw doubt upon these points, namely Wigand and Schacht: the state-
ments of the former as to matters of fact are far from sufficient to bear out the mass of
argument he has built upon them against the existence of sexes; in fact, his observations
were so imperfect, that he described the two parts of the archegonium, the papilla and the
enlarged embryo-sac, as distinct structures, while he never traced the origin of the new
plant at all. His observations may therefore be safely passed over. Schacht’s are more
complete, but he again only argues against the probability of a sexual conjunction, with
the preconceived notion that this must be analogous to what he erroneously believes to be
the conditions in the Phanerogamia; while his observations furnish facts which greatly
support the probability of an impregnation by the spermatozoids; the difficulties he
suggests being of little weight in comparison with those of accounting for the existence of
all the peculiar structures by any other hypothesis.

The opinions of all the rest are in favour of the impregnation (Thuret does not treat of
the archegonia); and the differences between them, except in the case of Suminski, are
unimportant in a physiological point of view, merely presenting questions of anatomical
and morphological interest. And since Suminski’s description of the mode of origin of
the embryo would be altogether at variance with what exists, not only in other plants, but
also in animals, and is opposed to the observations of all the rest of us (except the doubt-
ful support given by Von Mercklin), I cannot but repeat my belief that he was led away
from the facts by his imagination being preoccupied by Schleiden's doctrine of the impreg-
nation of the Phanerogamia.

These observations Dua Ferns have acquired vastly increased interest from the sub-
sequent investigations of Hofmeister, Mettenius and Nägeli on the allied Cryptogams, and
above all, from Hofmeister’s observations on the processes occurring in the impregnation
of the Coniferæ *. :

Not only have these investigations given us a satisfactory interpretation of the arche-
gonia and antheridia of the Mosses and Liverworts, but they have made known and
coordinated the existence of analogous phenomena in the diquisetecces, Ly copodiacere
and Rhizocarpeæ, and shown, moreover, that the bodies described by Mr. Brown in the
Conifers, under the name of ‘corpuscles,’ are analogous to the archegonia of the Crypto-
gams, so that a link is hereby formed between these groups and the higher flowering
plants.

136 MR. HENFREY ON THE DEVELOPMENT

It would be out of place to enter into a detailed examination of these discoveries at the
close of this long memoir. They are to be found in the work of Hofmeister * already
quoted in regard to the Ferns. I may also refer to a resumé of the present state of know-
ledge on these subjects, published by myself in the ‘ Annals of Natural History +,’ for the
facts and general conclusions to be derived from them, and to a Report furnished to the
British Association in 1851, for an account of the historical development of these questions
during late years.

I cannot conclude without once more directing attention to the many striking analogies
recently revealed between the phenomena of reproduction in plants and in animals. They
must excite the strongest interest in the minds of all those pursuing the study of biolo-
gical laws. Many of the facts rest, at present, it is true, upon the authority of but one or
two observers, and it can scarcely be doubted that much remains to be discovered before
all the details are sufficiently established. The investigation of the reproduction of Ferns
is the point which has been most pursued hitherto, and even here there is considerable
discrepancy in reference to anatomical conditions. My own observations have satisfied
me only after prolonged and careful study of the subject; for where we have to compare
successive stages in distinct preparations, and this by means of dissection of microscopic
structure, there are very numerous inlets for misconceptions. If I have fallen into errors,

I trust they may be soon detected by other observers, whom this memoir may attract to
similar researches.

XV. On Two Genera of Plants from Chile. By Joux Mins, Esq., F.R.S, F.L.S. fc.
Read November 18 and December 2, 1851.

AMONG the few very interesting plants which I was enabled to collect during my rapid
Journey over the Cordillera in 1825, were the two following, which being yet undescribed,
may perhaps claim the attention of the Linnean Society. The first evidently belongs to
the tribe of the Zriogoneæ, of which a monograph by Mr. Bentham was read before the
Society in 1835, and subsequently published in the 17th volume of its Transactions. It
differs from all others of the tribe in its habit, for its very slender ramifications are
always dichotomously divided in every axil, and its solitary involucre, on a lengthened
capillary pedicel, springs from the middle of each bifurcation; it is however easily distin-
guishable from the rest by the proportion of its floral parts in a manner to be presently
noticed. All the Hriogonee hitherto discovered in South America have been found on
the western side of the Andes, and this is probably the first instance known of their
occurrence on the eastern declivity.

The learned author of the monograph above quoted, states that he does not agree with
Dr. Meissner and M. DeCandolle, who infer the normal number of the stamens in the
Polygonaceæ to be double that of the lobes of the perigonium, and that in all instances
occurring with a less number of stamens, this diminution is alone attributable to the
abortion of those parts. Mr. Bentham, on the contrary, shows that this relation is not
at all manifest, and he endeavours to prove that the normal number of floral parts
is always ternary, the six lobes of the perigonium being biserial, the nine stamens in
three series, and the ovarium surmounted by three styles and three stigmata. This
arrangement, however, is far from general, for the greater number of genera present only
five divisions of the floral envelope, with six, eight or nine stamens. Atraphazxis, not-
withstanding, offers a binary arrangement of its parts, viz. four lobes in the perianthium
in two rows, six stamens with two styles, and two stigmata.

The discrepances here alluded to may, however, be reconciled, if we pay attention to the
following circumstances. There does not seem any apparent reason why botanists should
have constantly regarded the floral envelopes in the Polygonaceæ as a perigonium or
perianthium, words intended to express a confluence of calyx and corolla into one common
floral covering; but here the parts constituting such envelope manifestly bear the usual
characters of a distinct calyx and corolla, for the floral segments are divided to the base,
and exhibit their origin externally upon an annular hypogynous ring, that serves to sup-
port the stamens as well as the stipitate ovarium : they are always in two or more whorls,
are deeply imbricated, the external series being of a somewhat denser texture, and although
petaloid, these segments have every claim to be regarded as so many sepals, while the

VOL. XXI. U

more internal leaflets bear the usual characters of petals. Were this distinction once
admitted, and we were to conclude the normal arrangement to be ternary, and to allow
the existence of an occasional binary combination, by the suppression of some of its parts,
all the difficulties of its variable structure could be easily explained. In the solitary
instance where the floral envelopes are only three (as in Königia), we might look upon
it as an apetalous genus ; where they consist of six lobes, the three outer may be regarded
as sepals, and the others as petals; or when nine, the six interior lobes as a double row
of petals. In like manner, when five in number, we may conceive the two outer lobes
(which in such cases are always more exterior) to be sepals, and the other three to be
petals; when four or eight, the same distinction may be made by dividing them into
binary series. This hypothesis, though only a modification of Mr. Bentham’s, will obvi-
ously reduce the number of deviations from the normal rule. There does not indeed
appear any reason why the floral envelopes of the Polygonacee should not be entitled to
the same distinction into calyx and corolla, as is admitted, for instance, in the Polygalacee,
where the calyx is often comparatively large and petaloid in texture, or as in the Portu-
lacacee, where the same occurs, and where the number of sepals (different from that of
the petals) is only two, in the same manner as, according to my view, exist in Polygonum,
Fagopyrum, Coccoloba, Ceratogonum, Emex and Calligonum, in which last-mentioned
genus the two exterior leaflets are larger and marcescent, showing the difference of their
nature from the three petals, which remain persistent about the fruit. The same decadence
of the sepals and persistence of the corolla occur also in the Portulacacee. In many other
genera of the Polygonacee with six floral segments, the outer series, which are different.
in texture, fall away, while the petals remain, investing the achenium. This view of the
subject is much confirmed by the argument of Prof. Lindley*, where he offers very cogent
reasons for associating the Polygonacee with the Caryophyllacee and the Portulacacee,
with which orders they agree in the unsymmetrical inconstancy of their floral parts, in
their sepals being often of petaloid texture, in the insertion of their stamens upon a hypo-
gynous ring, quite free from the petals, in their somewhat stipitate ovarium, and in their
farinaceous albumen enclosing a curved embryo. The Caryophyllacee have also their
petioles somewhat vaginant.
All the Eriogonee hitherto known accord with the normal rule, as they present six floral
"mide in two series, nine stamens and three styles, but in the plant under considera-
on, we have an unusual deviation from the general disposition, for here we find a quater-
= arrangement, the involucre being generally 4-cleft, each flower having eight distinct,
ery imbricated segments, eight stamens fixed upon the hypogynous support or gyno-

phorus, and four styles and stigmata. In accordance with the views above suggested,

I shall therefore consider the four outer segm ca :
ents as a cal f fo
lobes as a corolla of four yx of four sepals, and the inner

digi petals. I will here remark, that in the same specimen I have
ough rarely, that some of the involucres contain flowers in which their parts

ins : FRANS. e. three sepals, three petals, six stamens, three styles and stigmata, but
e involucre in such case is still 4-pointed.

* Vegetable Kingdom, p. 50.

MR. J. MIERS ON TWO GENERA OF PLANTS FROM CHILE. 143

In Chorizema and Mucronea, the involucres are l-flowered, being 6-toothed in the
former and bidentate in the latter; in Eriogonum and Chorizanthe, the inflorescence is
generally terminal, and capitate in Mucronea, with three involucres, verticillately arranged
in each flowering axil; but this plant, differing from all others, offers only a single stipi-
tate involucre in each axil or dichotomy. From all these peculiarities, I naturally at first
concluded it would constitute a new genus, which I proposed to call Zetraraphis, closely
allied to the Oxytheca of Mr. Nuttall, described in the Journal of the Academy of Natural
Sciences of Philadelphia (2nd Ser. i. 169). Although agreeing with that description in
its similarity of habit, its linear radical leaves, a single few-flowered involucre in each
axil, supported on a filiform pedicel, with its teeth armed with long rigid bristles, Oxytheca
appeared to differ in its ramifications being trichotomous, in having only three sepals and
three petals, and these all united in a tube nearly to the summit, in having six stamens,
three styles and stigmata, in its achenium being compressed and 2-sided, and in its
embryo being placed excentrically in fleshy albumen. These differences appeared suffi-
ciently great to warrant the conclusion that the plant under consideration, though closely
allied, was generically distinct from Oxytheca, and hence it was desirable to compare it
with the Californian plant: this I had the good fortune to meet with in Sir W. Hooker's
Herbarium, communicated by Mr. Nuttall himself, as an authenticated specimen of his
Oxytheca dendroidea. I was greatly surprised, however, to find it so closely resembling
my own plant in external appearance, and so like it in dimension, in the dichotomous mode
of its growth, in the shape of its leaves, and in the size and aspect of its involucres and
flowers, as scarcely to be distinguished from it. In my own specimen, the chief specific
difference seemed to consist in the constant dichotomy of its ramifications, which are only
divided into three branches at its first basal joint, in the bracts at the division of the stems
not being quite divided to the base, its leaves not strongly revolute, the achenium not
compressed, 2-sided and lenticular, and its flowers, with rare exceptions, being 4-merous,
having their floral envelopes nearly divided to the base. Mr. Nuttall, in his generic cha-
racter, states that the flowers are either dicecious or moncecious, that in the female flowers
the perianth is closed to the summit and 6-toothed, that in the male and hermaphrodite
flowers it is shortly 6-cleft, and he hesitatingly gives the number of stamens to be six; it
must be remembered, however, that his examination was from dried specimens of plants
collected by Dr. Gamble in the Rocky Mountains. As Mr. Nuttall includes in his genus
Oxytheca, another section under the name of Gomphotheca, founded upon a very distinct
plant, with dioecious pentamerous flowers, possessing a very different habit; as he nowhere
states that the two other more legitimate species have moneecious flowers; as I have
not noticed the flowers of the plant from the Chilean Andes to be otherwise than perfectly
hermaphrodite; and as the floral characters of the Californian plants appear doubtfully
stated, or made to include two distinct groups, and at variance in many particulars with
the features I have observed,—I feel induced to remodel the generic features of Oxytheca
in the following manner, in accordance with the facts I have carefully noticed in my own
plant, modified in some degree by the circumstances stated by Mr. Nuttall.

This plant, about 4 or 5 inches high, is very dichotomously branched. A rosulate
cluster of about twenty radical leaves spring from the collar of a lengthened tap-root.
The leaves, linear, spathulate and attenuated into a slender petiole, are about 8 lines
long, 1 line broad, somewhat fleshy, opake, and are covered on each side with numerous
patent rigid hairs, each hair springing out of a prominent tubercle. A simple short terete
stem, 8 lines in length, rises out of the cluster of leaves, and is crowned at its summit by
a verticil of six acute bracts, vaginantly united at their base: out of this verticil spring
three equal branches, 11 lines long, each being in succession and with regularity dichoto-
caged ns into other more slender br anchlets, and their nodes, about 10 lines distant,
are each furnished at their base with three bracts, two being opposite the stems and one
en all equal, acute, aristate, and united into a vaginant cup about each axil: from

e middle of each of the first and of each successive dichotomy rises a capillary erect
og decus long, bearing at its summit an urceolate involucre, the tube of which is

MR. J. MIERS ON TWO GENERA OF PLANTS FROM CHILE. 145

marcescent but persistent floral envelopes is about 4 of a line long. The branchlets and
peduncles are sparsely beset with very short patent hairs, bearing a resinous gland at their
summit ; these are different from the hairs of the leaves, bracts and calyx, which are simple,
pointed, and spring out of elevated tubercles.

I found this plant, of which I was only able to collect a single specimen, in January
1825, in the main valley, on the eastern side of the great Cordillera, upon the road lead-
ing from Mendoza to Aconcagua, at a spot near the Estero de Santa Maria, which falls
into the river Tunuyan, about three leagues above the Punta de las Vacas.

The second plant I have to record is a nearly aphyllous shrub, with straight, erect,
virgate branches, terminating in spines, and evidently belongs to the Bignoniacee,
although in many points it varies from the usual structure of that Order. In that family
the ovarium, formed constantly of two carpels, is generally bilocular, with ovules com-
monly ascending or horizontal, attached to the margins of the dissepiment : its fruit is
usually a long capsule, more or less woody, 2- or spuriously 4-celled; the seeds are
numerous, generally winged, always much compressed, and their exalbuminous embryo
presents broad foliaceous cotyledons, cordate at both extremities. In the present instance
the ovarium is simply bilocular, with a few ovules suspended on the two faces of the thin
dissepiment ; the fruit is a small oval drupe, containing a single osseous indehiscent nut,
which is 1-celled by abortion, and contains only a single pendulous seed that entirely fills
the cavity: this is therefore quite apterous, oval, with a small thick superior radicle, and
- two plano-convex fleshy cotyledons, a structure quite anomalous in the Order.

I found this plant in the year 1825, upon the skirts of the eastern declivity of the
Cordillera, near Mendoza, on the margin of the desert tract called “La Travesia," where
it was also found by Dr. Gillies. I have proposed for it the generic name of Oxycladus,
from 080, acutus, and xAddoc, ramus, in reference to its spiny habit.

It is evident, from the facts just stated, that this genus does not conform with any of
the characters that mark the tribes into which the Order has been divided by botanists.
The genera that most nearly approach it in habit are the Catophractes of Don, figured in
the 18th volume of the Society's Transactions, plate 22, and the Rhigozum of Dr. Burchell,
both of which are spinose shrubs from South Africa; but these have both large yellow
flowers, and the seeds of the latter agree with the characters of the true Bignoniee. It
will therefore be necessary to place Oxycladus in a distinct tribe, and the Order may hence
be divided into the following sections.

Tribe 1. Brenonreæ. Capsule dehiscent, 2-celled, 2-valved, with numerous winged com-
pressed seeds attached to both sides of the dissepiment; embryo with flattened
foliaceous cotyledons.

Tribe 2. CRESCENTIER. Fruit drupaceous, woody, 2- or many-celled, with numerous
winged or compressed seeds; embryo with compressed fleshy cotyledons.

Tribe 3. OxyctapEsx. Fruit drupaceous, containing a single 1-celled, osseous, inde-
hiscent nut, with a solitary suspended, rounded seed; the embryo having a superior
radicle, with large and nearly hemispherical fleshy cotyledons.

This is a shrub about 8 feet high, with the habit of a woody leafless broom. The
branches have a very smooth bark, of a chestnut-brown colour, almost polished, and. the
young branchlets that bear the flowers look like spines, being subulate and mucronate, as
are also the ends of all the branches: the axils are opposite, but frequently one branch,
or both, are barren, which adds more to its spinescent appearance. About two or three
flowers spring out, of each axil on the spine-like branchlets, bearing at the foot of the
peduncles several minute, curved, smooth, linear leaflets, about half a line in length. The
peduncles are about a line long ; the smooth tubular calyx, crowned with five somewhat
unequal, short, triangular teeth, is 3 lines in length; the corolla is tubular, of a bluish
colour, and about 6 lines long; the tube is little more than a line in diameter, is pubescent

XVI. On Two New Genera of Fungi. By the Rev. M. J. L6 M.A., F.L.S. $c.
Read June 1, 1852.

THE illustrious mycologist, Elias Fries, on more than one occasion, expresses the far
greater pleasure that he has experienced in ascertaining with complete certainty a single
synonym of the earlier writers on Fungi, than in discovering many new species; a senti-
ment which will meet a responsive echo in the approbation of most true lovers of science.
There is indeed a great satisfaction in clearing up a point hitherto obscure; in finding
that the pioneers of science, with all their disadvantages, were so far correct in their
observations, and therefore worthy of trust in other particulars; the very subjects too are
often interesting in an historical point of view; and not only so, but there is often much
valuable information to be derived from their mode of regarding matters respecting which,
for the most part, no scientific theories or prejudices existed, whatever other analogous
drawbacks there might be, insomuch that on many points really juster views were enter-
tained than by many of their successors. Such works as those of Micheli and Schmidel
will repay the most attentive study, and many a circumstance has from time to time been
brought forward as a new and important discovery, which they and others of their con-
temporaries had already accurately observed; while, on the other hand, from a careless
inspection of their figures without due attention to the context, they have been made to
vouch for facts respecting which they had no knowledge. To take a single instance in
that branch of botany to which attention is more particularly called in the present memoir,
and to which it is proposed to add two new genera, either founded on forms observed and
described by the older botanists, or illustrated by matter furnished by them, but not
recognized by more modern writers on the subject, the true structure of the hymenium
of Agarics is accurately represented by Müller in Agaricus comatus, in an early figure of
the ‘ Flora Danica,’ whereas the figure in which Micheli is supposed to have represented
that structure is meant to express something quite different, the simple circumstance of
the quaternate disposition of the spores in Agarics being the only correlative fact known
to that author, as appears from his text, which is usually too positive and luminous to
admit of much question. m
The objects to which the attention of the Society is now drawn are closely related to
two which are figured, the one by Battarra and the other by Bulliard, though it should
seem not absolutely identical. The first noticed shall be that which calls to mind a figure
in the well-known work of the Italian botanist on the Fungi growing in the neighbourhood
of Arimini, a work remarkable for its excellent illustrations and general faithfulness, and
which may frequently be consulted with profit at the present day. The first edition of
this work appeared in 1755, and a second edition was published in 1759, without however

any alteration in the matter.

150 REV. M. J. BERKELEY ON TWO NEW GENERA OF FUNGI.

In the fortieth table a figure is given of a Phallus which has puzzled all succeeding
botanists. Paulet copies it indeed in his large treatise on Fungi, colouring it after the
description, and proposing it as a true figure of Phallus caninus, Hudson, to which how-
ever it bears at first sight but a remote resemblance. Fries says of it, under Phallus
caninus, “ Phallus exilis Marattæ, Batt. Arim. p. 76. t. XL. F. nisi preecedentis icon
erronea affinis species*." It seems, however, judging from the other figures contained in
the volume, impossible that he should have gone out of his way to make anything so
unlike the ordinary form of fungus in question. The account besides is too circumstantial
to admit of much doubt. The fungus, Battarra informs us, was found by Father Maratta
in the neighbourhood of Rome (ultra Genzanum), on the 5th of October, 1736, in à wood
known by the name of Li Disertini, and communicated to the author in May 1754.
Several specimens were found in a heap of rotten leaves. The volva is described as dirty
white, coriaceous, and filled with a mucilaginous substance as in other species of Phallus.
From this arose a club-shaped cellular receptacle, hollow within, the upper part being even
and solid within (meaning probably that it was imperforate), and covered with a crust
which was red when the fungus was young, but when it had arrived at maturity, the top
was green, with a zone of red beneath it, the lower portion of the stem being dirty white,
sprinkled with reddish brown superficial specks. When the fungus was passed maturity,
the upper portion passed into a foetid fluid. |

It should seem then that Battarra did not indeed see the fungus when fresh, and that
his figure was taken from a dried specimen, for he says nothing of any drawing; but it is
very difficult to conceive how a fungus tapering to a point, as exhibited in Sowerby’s figure
of Phallus caninus, could by any mode of drying assume the broadly clavate form exhibited
by the figure. l

A fungus, however, has been lately found by H. W. Ravenel, Esq., near the Santee
River, South Carolina, which exhibits the peculiar form of that of Battarra, and when for-
warded to me by the Rev. M. A. Curtis, was noticed as differing greatly in structure from
other species of Phallus, in its not showing the slightest distinction between the stem and
hymenium. It is true that at a later period specimens of the same species were found b
Mr. Ravenel exhibiting the same form as that of Phallus caninus but wi d

species of Phallus. We may, therefore, taking both the European and American species
together, conclude, with tolerable certainty, that after all the figure of Battarra does indeed
represent a peculiar state of the well-known species. No doubt whatever rests on the
mind of Mr. Ravenel as to the identity of the clavate and more fusiform individuals of '
his plant, though, before ample materials had been collected, he had formed a different
opinion.

Having, as far as the materials whick have been collected permit, cleared up the very
obscure plant of Battarra, I shall now advert more especially to that from South Carolina,
which differs from Phallus caninus, not only in colour and a more compact texture, but
in the important point of having the receptacle perforated.

In Phallus caninus the cells of the head are horizontal, compact, much smaller and
quite different from those of the stem; in the new fungus, the cells of the head differ
little in size, and are more numerous and not arranged horizontally. Though much stress
cannot be laid on the clavate form of certain individuals, the structure, taken in conjunc-
tion with the perforated pileus, completely justifies the proposition of a new genus for its
reception, unless such genera as Dictyophora, Mutinus, Dictyophallus, &c. are to be
rejected as mere members of the genus Phallus. Indeed, though Fries does not consider
Dictyophora, so remarkable for its beautiful reticulated veil-like appendage, as separable
from Phallus, he has proposed a distinct genus, Mutinus (formerly Oynophallus), for the
reception of Phallus caninus; in his“ Summa Vegetabilium Scandinaviw.' On the same
principles our M must be generically distinct. The genus then may be characterized
as follows :—

Gen. CoRYNITES, Berkeley et Curtis.

Uterus rotundatus è membranâ duplici gelatinâ distentá compositus, lobato-rumpens. Receptaculum cum
stipite elongato celluloso-cribroso omninó continuum, obtusum, perforatum, massá sporiferá primüm

discreto, apice perforato.

C. RAVENELI, n. sp.

On sandy ground, in grassy places. Autumn. Santee River. Curtis, Nos. 29573,3037. Ravenel, No. 844.

Egg globose, 3 of an inch in diameter. Volva bursting in two or three lobes closely applied to the stem.
Stem 11-2 inches high, 4-5 lines thick, bright red, coarsely cribrose, attenuated below, above con-
fluent with the receptacle, which is sometimes broadly clavate, sometimes conical, but always more
or less obtuse, pervious at the apex, sometimes half as long as the stem. Mass of spores dark olive,
soon washed off. Odour heavy and nauseous, but only perceptible when the hymenium is —
near to the nose.

Extreme forms are very different; some specimens approaching to the more ordinary
form of Mutinus caninus, while others exactly resemble what is figured by Battarra.

The second subject to which I beg leave to call the attention of the Society, is to a
group of fungi, of which Spherocarpus capsulifer, Bulliard, is evidently the type. Though
the description and figures are far from superficial, they appear for the most part to have

been neglected by authors. As far as I have been able to discover, there are no notices of
x2

the species, except by French botanists, and these appear to be for the most part mere com-
pilations from Bulliard. DeCandolle’s account, for instance, in the second volume of the
‘Flore Francaise,’ is only a transcript, as is also that of Chevallier; who adds to what
DeCandolle says the circumstance mentioned by Bulliard, that when the fructifying mass
is placed in water, the spores separate from one another as if they proceeded from a cap-
sule, a circumstance which I have observed in one of the species, though not in the two
which most nearly resemble the plant of Bulliard.

Duby next gives the characters of a supposed Physarwm, under the name of P.? capsu-
liferum, but as he describes the flocci as black, his plant cannot be the species of Bulliard ;
and his remark that Desmazières, who published Didymium cinereum at No. 272 of his
* Plantes Cryptogames du Nord de France,' thinks it may possibly be the same with that
species, is conclusive as to the point, even though Bulliard has referred to Batsch's figure
as a synonym of his Spherocarpus capsulifer.

These are all the notices I can find of this species. It is not in the General Index to
Fries’ ‘Systema Mycologicum,’ nor do I observe any notice of it in the text of his work,
` where so singular a production might have been expected to claim observation. Fries,
indeed, in his general remarks, says that conglobated spores are described in several
Myxogastres, but that such states are, according to his observations, always abnormal ;
which may be the reason why he has not noticed the species of Bulliard.

That the spores are, however, essentially conglobated in the species under consideration,
and do not form mere accidental clusters, arising from inequable distribution of moisture
amongst the mass, or from any other mechanical cause, is most evident under the micro-
scope, the external spores being indeed always attached to a larger body in the centre, so
that, when they are quite disunited, the size is seen to vary considerably ; and in one spe-
cies, where they are evidently echinulate, the little points are confined to those portions
which were exposed after the fashion of the achzenia in Rhagadiolus edulis ; besides which,
in an early stage of growth they are contained in a common sac. There is no doubt that
‘several other Physara will be found to possess the same structure, and possibly all those
species which have lamine rather than flocci; and now that attention has been called to
ve D other instances may be found in other genera affording solid grounds for

in our Transactions, I have ascertained, as also in the present case, that they are pro-

duced within a vesicle, as in Hymenogaster vulgaris, Tulasne; thus confirming at once

Mr. Bowman’s curious genus, and M. Tulasne’s observation of a similar anomaly in a

different group of fungi; and in the two other genera they form little radiating fascicles.

The figures prepared by Corda for his sixth fasciculus, of which, before his ill-fated voyage,

he kindly sent me a copy, illustrate this admirably in the case of Reticularia maxima and

argentea. Tripotrichia, Corda, has at first sight some resemblance, but the spores have
short pedicels, which seems decisive as to their not being conglobated. The genus may
be characterized as follows :—

XVII. On the Habits and Structure of the Great Bustard (Otis tarda of Linneus).
By WILLIAM YARRELL, Esq., V.P. and Treas. Linn. Soc. $c.

Read January 18, 1853.

SOME kind friends having supplied me with various particulars relating to the habits
of the Great Bustard (Otis tarda of Linnzeus), most of which, as far as I am aware, have
. not been made public, I have endeavoured to put these materials together, in the belief

that they might be found sufficiently interesting to be communicated at a meeting of the
Linnean Society; the great scarcity, or rather, the now rare occurrence of the bird in this
country, affording but few opportunities for observation.

The first communication came from C. A. Nicholson, Esq.; of Balrath Kells, in the
county of Meath, and was as follows :—

* You will perhaps be interested by the following few remarks on the habits of the

Great Bustard, as observed by me in the neighbourhood of Seville, where they exist in
large numbers.
- “The males begin to arrive in the cultivated part of the country at the beginning of
February; they come in flocks, varying from seven to fifty-three, the smallest and largest
: numbers I have seen together at that season of the year. The old birds always go together ;
those of a year old, which are much smaller, never mix with them. The young birds have
neither beard nor pouch.

* The females do not arrive till the beginning of April, and come singly, or at most in
pairs : as soon as they arrive the flocks of males begin to break up, and after about three
weeks you seldom meet more than three or four old males together, they being very fre-
quently to be met with singly. At this time, on a fine day, they spread their tails like
. Turkey cocks, drooping their wings and expanding their pouches. Being perfectly white
under the tail, they can be seen at a great distance while in this attitude; I have how-
ever never seen a female near a cock, as apparently they live quite separate. During the
month of May the cocks entirely disappear from the cultivated lands, leaving the hens
behind them; they, I have every reason to believe, go down to the extensive grass marshes
which stretch along the banks of the Guadalquivir. The young bustards are hatched in
the large corn plains about Seville, and are able to take care of themselves when the corn
is cut in July. At the end of that month, when all the corn is cut and no cover remains,
the young birds and hens follow the cocks to the marisma, as they call these great marshes
in Spain. | |

“The birds are very difficult to shoot, and many a long day I have spent without any
success in hunting them about. The only chance is, to hide in a ravine or ditch, and send
men who know the country round the birds to try and drive them over you. They
sometimes succeed in this, but not very often. The heaviest bird I shot weighed 28 lbs. ;

156 MR. YARRELL ON THE HABITS AND

this was before the hens came, which may perhaps account for this bird being two pounds
heavier than any I shot afterwards. The largest bird, from tip to tip of wing, measured
7 feet 3 inches; this bird weighed 261bs. The 28 Ibs. bird measured but 7 feet 1 inch.

“The birds of a year old weigh from 8 to 10 Ibs., and are much the best to eat. I did
not shoot a hen. ; |

« AIL the birds I shot had their stomachs perfectly crammed with barley, both stalks
and ears, the leaves of a large-leaved green weed, and a kind of black beetle. The pouch
is surrounded by a layer of fat fully an inch thick. I may add that the bustards when
flushed generally fly two miles or more, sometimes at least a hundred yards high. "They
never try to run ; one that I had winged making the most awkward attempt possible to
get away from mie, and though a young bird, showing much more disposition to fight than
to get away by running. They fly with a regular flap of the wings, and much faster than
they appear to go. I cannot imagine greyhounds being able to catch bustards, though
there seems to be good authority for believing they did. "There were a great many Little
. Bustards about also, but I never followed them, as I liked the large ones better.”

To my friend John Wolley, Jun., a good ornithologist, who had been in Spain and North
Africa, I wrote in reference to the Great Bustard, and was immediately favoured with the
following answer :—

“ My very little acquaintance with North Africa does not extend beyond the neighbour-
hood of Tangier, and there I did not see the Great Bustard, nor have I received its eggs
from that quarter in the several packets which have been forwarded to me; but this
proves nothing; it only renders it probable that this bird is not common in the immediate
vicinity of that town.

* Of Spain I have almost equally little to say. One day, about the month of Septem-
ber, going up the Guadalquivir in a steam-boat to Seville, I saw several flocks of the Great
Bustard at no great distance from the river banks, on the level, and at that time of the
year burnt up, plains which extend, almost without trees or enclosure, on each side of the
Guadalquivir. These flocks consisted, as I remember, of four or five birds each ; and from
the deck of the vessel, which was almost on a level with the land, they appeared to be
walking in file, some with their heads down, and reminding one of Gilbert White's note,
* Bustards upon the downs look like deer in the distance. This appearance of walking in |
a row was probably deceptive. There was nothing in their manner to give the impression
that they were timid, or very cautious, but one at least of a party frequently had its head
raised as the steamer passed at a few hundred yards’ distance, and with the help of my .
glass I thought this was generally a cock bird. On one occasion, as the boat came sud- -
denly round a corner, several of them rose together from the edge of the water, springing
hastily to the height of forty or fifty feet, nearl di d
| ; y perpendicularly, partly perhaps to clear
the bank, and then turning suddenly and somewhat clumsily, and after a few more not —
rapid strokes, sailing along with the arched form of wing so general in game birds.

“I have now told you all I know about the Great Bustard in Spain. I wish I had
more to say about it. I was told that the Spanish name was Abutarda, which is, I should
imagine, connected in some way with the specific name ‘ tarda,’ for the bird can hardly be
called ‘slow,’ but I do not know who gave it its scientific appellation. On the occasion I

STRUCTURE OF THE GREAT BUSTARD. 157

have referred to, a Spaniard on board the steamer told me that two or three months earlier
in the year was the time for shooting the bird, and that then they were not difficult to
approach with the assistance of cattle or carts, if I remember right. This would of course
. be in the breeding season.”

. My next communication was received from John Britton, Esq., so favourably known for
the great extent of his interesting labours. Tt is copied from a letter in his possession,
. with permission to use it, and refers to Salisbury Plain:— ——

“A man, about 4 o'clock of a fine morning in June 1801, was coming on horseback
from Tinhead to Tilshead. While at, or near, an enclosure called Asking's Penning, one
mile from the village of Tilshead, he saw over his head, about sixty yards high as near as
he could estimate, a large bird, which afterwards proved to be a Bustard. The bird
alighted on the ground immediately before the horse, which it indicated a disposition to
attack, and in fact very soon began the onset. The man alighted, and getting hold of
the bird endeavoured to secure it; and after struggling with it nearly an hour he suc-
ceeded, and brought it to Mr. J. Bartley of Tilshead, to whose house he was going. Not
knowing the value of such a bird, he offered it to Mr. Bartley as a present; but Mr. Bart-
ley declined to accept it as such, though he much wished to have it, and after repeated
solicitations prevailed on the man to receive for it a small sum, with which he was per-
fectly satisfied. During the first week that Mr. Bartley had this bird in his possession it
was not known to eat anything; however, at length it became very tame, and would at
last ‚receive its food from its patron's hands, but still continued shy in the presence of
strangers. Its principal food was birds, chiefly sparrows, which it swallowed whole in
the feathers with a great deal of avidity. "The flowers of charlock and the leaves of rape
formed also other parts of its food. Mice it would likewise eat, and in short almost any
other animal substance. The food on passing into the stomach was observed to go round
the back part of the neck. |

* Mr. Bartley is of opinion that the idea of the Bustard's drinking is erroneous ; in sup-
port of which he says, that during the time this Bustard was in his possession, whieh was
from June till the August following, it had not a drop of water given it, after two or three
weeks at first. This fact he considers as a proof that the generally received opinion of a
Bustard's drinking is untrue.

“This bird was judged to weigh upwards of 20 Ibs., and to measure between the extre-
mities of its wings when extended about 5 feet, and its height was about 91 feet. Its
plumage was beautiful; and from its gait, which was extremely majestic, a spectator
would be led to infer that it was sensible of its own superiority over others of the feathered
tribe. :

* In August Mr. Bartley sold this noble bird to Lord Temple for the sum of thirty
en Bustard inhabits the extensive downs of Salisbury Plain; but its race en
almost extirpated. It is thought that not more than three or four tele,
Some time in the last summer (viz. 1801), while Mr. Bartley had this bird in his
session, a nest, supposed to belong to this bird, or at least to his mate, for Mr. Bartley’s

bird was judged to be a male, was found in a wheat-field on Market Lavington Down.
Y
VOL. XXI.

158 MR. YARRELL ON THE HABITS AND

It contained two eggs; they sometimes lay three, though very seldom; they are about
the size of those of a goose, of a pale olive-brown, with small spots of a darker hue.’
The nest was made upon the ground, by scratching a hole in the earth, and lined with
a little grass. The eggs were rotten, and had probably undergone a period of incu-
bation.

“€ An instance of a Bustard attacking a human being, or even a brute animal, of any
considerable size, was, I believe, never before heard of; and that two instances of this kind
should occur so nearly together may be considered very remarkable. About a fortnight
subsequent to the taking of this bird, Mr. Grant, a respectable farmer of Tilshead, was
returning from Warminster Market, and near Tilshead Lodge, which is something more
than half a mile from the village, was attacked in a similar manner, by, as it is thought,
the mate of the same bird. Mr. Grant’s horse being rather high-mettled, took fright,
became unmanageable and ran off, and consequently Mr. Grant was compelled to abandon
his design of endeavouring to capture the bird.”

From J. H. Gurney, Esq., of Norwich, I received a communication to the following
effect :—

* As far as I can learn, the last Bustard killed in Norfolk was a female, which
was shot at Lexham near Swaffham, towards the end of the year 1838. The small flock,
of which this bird was one, had for some years previously consisted of females only, the
eggs of which were frequently pieked up, having been dropped about at random in con-
sequence of the absence of male birds, the latter having become extinct at an earlier date.

“ Before horse-hoeing was practised, the large wheat-fields of West Norfolk were often
left unhoed, and the Bustards were able to nest in them undisturbed ; but horse-hoeing
rapidly improved the farming and destroyed the nesting of the Bustard."

My worthy friend Frederick J. Nash, Esq., of Bishops-Stortford, has several times told
me, that when he was a young man, and then taking the field as a sportsman, he once
saw nine flights of Bustards in one day, not far from Thetford in Norfolk. Some of these
birds were probably seen more than once, but at that time, about the beginning of the
present century, the country between Thetford and Brandon, and from thence southward

STRUCTURE OF THE GREAT BUSTARD. 159

This specimen is in the possession of Dr. Plomley, who recorded the circumstance in the
* Zoologist ’ for the year 1850, at page 2700.

The third was shot on the 31st December, 1851, in Devonshire. This specimen was
preserved by Mr. Drax, and is now in the possession of J. G. Newton, Esq., of Millaton
Bridestow, as recorded in the * Naturalist’ for 1852, page 33.

I had long wished to have an opportunity of examining the body of a male Bustard to
inspect the gular pouch described by Daines Barrington, in his * Miscellanies, 1781, and by
Edwards in his ‘ Gleanings in Natural History,’ 1811, and from thence copied by Bewick
and myself, but it was not till lately that an opportunity offered. About four years ago
the Zoological Society obtained by purchase six or seven young Bustards from Germany. -
One of these birds, a male, died within a year: the body was examined by Mr. Mitchell
and myself, but no gular pouch was found. This we then attributed to the youth of the
bird. During the past summer of 1852 one of the males of these birds was frequently
observed courting a female. His appearance at such a time was singular: the wings are
lowered to the ground, and while covering the sides, the most anterior parts of both wings
are brought round in front, so that the bird appears to be surrounded by a circle of his
largest wing-feathers: the head and neck are passed backward, and so depressed that the
occipital portion of the head touches his back, and in this attitude he struts round his
favourite. No inflation of the neck was observed. The females are timid and rather shy.
Constant exposure to numerous visitors at the Gardens, with the want of sufficient space
for seclusion, probably interfered, as no eggs were produced.

In the month of December last this male bustard, believed to be four years old, unfor-
tunately died, and Mr. Mitchell very kindly allowed me to examine this adult bird.

To give an indication of what I expected to find, I may first quote the words in Edwards’s
‘Gleanings ’ :—

“A remarkable anatomical peculiarity in the male of the Great Bustard, first dis-
covered by Dr. James Douglas of the College of Physicians in London.

* It is a pouch or bag to hold fresh water, which supplies the bird in dry places when
distant from waters: the entrance into it is between the under side of the tongue and the
lower mandible of the bill. I poured into this bag, before the head was taken off, full
seven wine pints, before it ran over. "This bag is wanting in the hen."

My examination of the mature male Bustard sent to me from the Zoological Society's
Gardens was confined to the neck only. I very carefully divided the skin, in a straight
line from the union of the two branches of the lower mandible to the angle of the furcular
bone or merrythought. On separating the edge of this skin on each side to the right and
. left, a thin delicate transparent membrane was seen covering, and firmly attached to, the
anterior surface of the trachea or windpipe, which lies close to the inner surface of the
common skin. Separating the skin still wider, there was on each side of the trachea an
. elongated narrow column of membrane investing and attached to the blood-vessels and
ordinary glands of the neck, and extended downwards was attached to the lateral branch
of the furcula on its own side. The esophagus inclines to the right side of the neck in
its passage downward. There was no opening under the tongue, and I failed in various

attempts to distend any part of the membranes below, either by fluid or by air.

160 MR. YARRELL ON THE HABITS OF THE GREAT BUSTARD.

I was disappointed, and began to doubt the accuracy of my own investigation, but on
turning to the volume containing a translation of the anatomical descriptions of the many
animals dissected by the Royal Academy of Sciences at Paris, published here by an order
of the Council of the Royal Society of London, 1702, I found that although ‘the dissec-
tions of six Great Bustards, and all of them males, were therein detailed, beginning at
page 197, there was no mention of a gular pouch, and the following extracts are in
accordance with the observations on the soft parts already described :—** The rings of the
Aspera arteria (windpipe) were entire. In some of the subjects there was on each side
a caruncle or red gland, immediately fastened to the Aspera arteria and to the carotids.
In the palate and lower part of the beak there was under the membrane which covers
these parts, several glandular bodies which did open into the cavity of the mouth by
several very visible tubes.” |

Cuvier, in his * Lecons d' Anatomie Comparée,' 1799, dwells at some length on the blood-
vessels, glands and cellular tissue of the neck in birds, but he does not refer to any pecu-
liarity in the neck of the Great Bustard. |

Unwilling, however, to offer my statement to the notice of the Linnean Society without
consulting the best living authority in this country, namely Professor Owen, I mentioned
the subject to him, and had the satisfaction to find that Mr. Owen agreed with me
entirely—that there is in the Great Bustard neither an orifice under the tongue, nor a
gular pouch; and he had the kindness to send me a written note in confirmation. ‘The
following was the result of my dissection of a full-grown Bustard, with the view of obtain-
ing a preparation of the alleged gular pouch for the Physiological Series :—No. 772 Q.
The head of a Bustard, Otis tarda, with the mouth and fauces exposed, showing the
glandular orifices between the rami of the lower jaw, the tongue, glottis, internal nostril
and Eustachian orifice. There is no trace of a gular pouch.” The preparation has this
description in the Museum Gallery Catalogue.

I am therefore disposed to consider that Dr. Douglas was mistaken as to the species of
bird examined ; and that the summer seasonal enlargement of the glands and cellular
structure in the neck of the Great Bustard, accompanied as it is by the assumption of cer-
| > PORUM tee called the beard, and a stripe of naked blue skin on each side of

and neck in our Turkey cock in spring, and to the increase in the size of the glands of the
neck seen in the males of Deer during their rutting time.

XVIII. On the Ocelli in the Genus Anthophorabia.
By GEORGE Newport, Esq., F.R.S., F.L.S. Se.

Read April 19, 1853.

SINCE the publication of my observations on the genus Anthophorabia, in the Transac-
tions of the Society*, my attention has again been directed to the peculiarities exhibited
by the principal organs of sense, and to the differences which exist in the comparative
anatomy of these structures, the eyes, in the two sexes of insects of this genus. I now
propose to offer a few remarks on the nature of these differences, in accordance with
certain well-established laws in the anatomy and development of animals, and in extension
of views which I have already begun to elucidate in the memoirs I have had the pleasure
of communicating to this Society on the anatomy and development of Meloé.

On a former occasion t I pointed out the curious circumstance that the male individuals -
of this genus have ocelli at the sides of the head, instead of the large compound eyes which
exist in the females, and other Hymenoptera, and that they have also three ocelli on
the vertex. The existence of lateral ocelli in Anthophorabia, at precisely similar parts of
the head as the compound eyes and ocelli in other insects, is incontrovertible, and yet it
has been denied. It is equally certain that these structures, as I shall endeavour to show,
are true representatives of organs of vision ; and that, imperfect as they are, they are good
generic distinctions.

The appearance which they exhibit under the microscope is, indeed, such as might
readily induce those who are imperfectly acquainted with the laws of structural anatomy
to regard them as merely coloured portions of the surface of the head, and not as ocelli,
or organs of vision in any stage of development ; and such observers might feel themselves
supported in this opinion by the circumstance that there are also appearances on the
cephalo-thorax of certain species of Arachnida, in the precise situation of ocelli in other
species, which, by. some, are regarded as mere spots or markings of the tegument, and not
as the representatives of eyes.

This opinion would be fully entitled to respect, so long as its authors maintained it as
am opinion, and made no attempt to enforce it in opposition to principles which are sus-
ceptible of demonstration, or to support it by supposed analogies.

To judge aright of the nature of the lateral ocelli, in the male uopo, we must
not only remember that they correspond precisely, in situation, to the eyes in the female,
but must also call to mind what are the essential conditions of a structure which is spe-
cially destined for the appreciation of light.

Professor Owen has stated } that the lowest form of this structure in Fishes is—

* a minute tegumentary follicle coated by dark pigment, which receives the end of a
special cerebral nerve,” and he exemplifies this by reference to the eye of the Myxine and |
Lancelet, and also to that of the Amblyopsis speleus*, a fish which constantly resides in the
dark caverns of Kentucky, and which at first was supposed to be completely eyeless, but
which now is shown by Tellkampf + to possess eyes ;—the fish, Amblyopsis, like the insect,
Anthophorabia, having been misobserved in this respect, through imperfect investigation.
The condition of the eye in these low forms of the organ in Fishes is very similar to that
of the simple eyes in their lowest form in Insects. The eye of the insect, as long ago
shown in my paper on Meloe, read to this Society, is, like all the external organs of its
body, a tegumentary structure. It originates in a little cavity, pit, or simple depression,
in the substance of the tegumentary portion of the head, which, lined with pigmentary
substance, is more or less deep in proportion to the perfection of the organ, and it is
covered in on its exterior by a transparent portion of the external layer of tegument, which
forms the cornea, and affords a free passage to light, which is received by the retina, or
termination of a cerebral nerve at the base of the organ. This is the principle of construc-
tion, and the condition of the ocellus, or simple eye in Anthophorabia (Ta. X. fig. 10 b, c),
as in other insects. In the most perfect form of ocellus in Insects, an iris and a lens also
are present. The ocelli of the vertex, in Anthophorabia, are the most perfect in their
structure (c). The cornea is quite transparent, nearly circular in shape, and well-defined
at its margins, as may be seen, with some care of manipulation, with the microscope;
but it is much flattened, and forms only a very slight portion of a segment of a sphere.
The choroid is deeply coloured, being formed of distinct pigmentary granules, which clothe
the shallow cup-shaped cavity of the organ. The presence of this pigmentary choroid
indicates the light-receiving function of the organ, but whether this organ be simply
capable of appreciating light, or whether also of distinguishing form, its focal length of
vision must necessarily be very short, so that in this respect the facts of structure accord
well with the observed and with the presumed habits of the insect.

The ocelli at the sides of the head (b) have the same general structure as those on the
vertex, but are much more imperfect, in so far as respects the choroid ; so that these ocelli
may fairly be regarded as simple appreciators of light. The form of the cornea in these
is an elongated oval, or lozenge-shape.

In all well-ascertained conditions of the simple eye in insects, the organ is found to con-
tain, in addition to the parts mentioned, a concentrating refracting medium, a lens-like
body, which is situated immediately behind the cornea, as was shown by Müller in the
Arachnida}. This lens-like body does, I believe, exist in the female Anthophorabia ; but
whether this structure, on which chiefly distinct vision and the power of the single eye of

we or. arene by the integument ” (Ray Society, Reports on Zoology, 1847, p. 563). This is exactly what might

expected, seeing that, in all animals, the cornea is, originally, continuous with and forms part of the tegument.

distinguishing forms depend, exists in the most perfect of the eyes of the male, those of
the vertex, I am not yet entirely satisfied. I have certainly detected appearances, in the
nymph or pupa state of the male (fig. 10 2), which have led me to think that the Jens is then
present; but I have not satisfied myself of this in the perfect insect, and hence the ap-
pearances seen may have been due simply to the vitreous body, as it exists in some of the
lower forms of the eye among the Annelida.

‘Whether, however, the lens does or does not exist, is of little importance with reference
to the simple question as to whether these structures in the male Anthophorabia are the
true homologues of the eyes in the female. That they are so I have not the slightest
hesitation, after what I have shown, in affirming. The presence of a cornea, which covers
a chamber lined with pigment, is sufficient proof to the physiologist and anatomist of the
nature of the function of the structure.

The form of the cornea, however, shows that the field of vision is very limited. The
cornea, as already stated, is but very slightly convex, being almost level with the surface
of the head. This fact may have conducted some to the opinion that these are not visual
organs. But neither the actual size of a simple eye, its form, nor the degree of its con-
vewity, has any necessary connexion with the simple faculty of perceiving light. The
convexity of the cornea has relation only to the extent of angle, or field of sight. The
more convex, and the more elevated the eye is above the surface of the head, the greater
proportion of a sphere does it necessarily include; and, as long ago shown by Prof. Müller,
the greater the segment of a sphere formed by the eye, the greater is its expanse, or field
of vision; while, on the contrary, the flatter or more depressed it is the more limited is
this field, and the shallower the chamber the shorter is its focal distance.

The presence of the Jens in the simple eye is essential to rendering the sight of images,
and the appreciation of form, more or less perfect; and it does this in proportion to the
more or less correct relation which it bears to other conditions coexistent with it.

With regard to the nerves supplied to these eyes, I may state that although I have not
been able to trace those of the vertex so satisfactorily in the male Anthophorabia as I
could have wished, owing to the numerous muscular fibres which run parallel to them,
yet I have succeeded in tracing the optic nerve (d d) from the side of the cephalic ganglion,
or rudimentary brain (d), transversely, in the direction of one of the lateral ocelli (2) ;
and I believe, also, that I have distinguished the nerve which goes to the middle eye of the
vertex (c). The nervous trunk which is given to the middle ocellus in Insects I have
already shown, in my paper on P/eronarcys*, is formed of two closely approximated
nerves, one from each cephalic ganglion, as found by a careful dissection of that insect, and
also of several Hymenoptera; and this probably is its condition in all other insects with
three ocelli on the upper surface of the head.

I may here also refer to what is stated in my paper on Meloet, that there seems reason
to think that in the Arachnida, and probably also in insects, the ocelli originate in the
same way as the dermal tubercles, from which they appear to differ chiefly in the mod
of development of their nuclei and nucleoli.

* Linn. Trans. vol. xx. p. 440. + Ibid. vol. xx. p. 342.

164 MR. NEWPORT ON THE OCELLI

Further I may mention, with regard to the question concerning the eye-spots in the
Arachnida, that I have found by dissection in the Scorpionide, not only that these are
always situated in the exact place of eyes in other species, but also that they always
receive a nervous filament from the same optie nerve which supplies the distinctly recog-
nised organs of vision.

These facts, I trust, will be sufficient to show the general correctness of the description
which I originally gave of the male Anthophorabia, that it is distinguished by the pos-
session of ocelli, both at the sides of the head and on the vertex.

May 9, 1853.—To the foregoing remarks I may add a word on the condition of the eyes
in the so-called blind Crustaceans from the caves of Kentucky. Distinet eyes exist both
in Triura cavernicola and in Astacus pellucidus, Tellk. In Triura the eyes have very
short pedicles, and are almost close together. In Astacus (fig. 11) they are partially
concealed beneath the front of the head (4); their pedicles are conical, much shorter than
in other species of the genus, and possess but little power of motion. The eye itself
(fig. 12 and 134), although existing as a distinct structure, is destitute of a pigmentary
choroid, in which respect it may be compared to the eye of the Albino. But the hardened
tegument which clothes the entire organ is thinnest-and most transparent in that part
which forms the cornea (3) in other crustaceans; so that, although the eye may be un-
fitted for distinguishing form, the creature may yet possess the faculty of perceiving the
small amount of actinic rays of light which penetrate into its subterranean abode. The .
cornea also exhibits an appearance of being divided into a few imperfect corneales at the
apex of the organ (fig. 14), and the structure behind these into chambers, to which a small
but distinct optic nerve is given (fig. 13 d d).

Probably other Articulata, which have been supposed to be entirely destitute of eyes,

which covers the place of the supposed lost organ thinner and more permeable to light

to infer that this may prove to be the fact in all,
from the already acknowledged susceptibility of some of the supposed eyeless insects to
the presence of light; and also from the cireumstance that in one of the Coleoptera, and .

in an Orthopterous insect, of the dark caves, Adelops hirtus and Phalangopsis ?, the
eye, as in others of the tribe, is distinctly indicated, as already shown by Tellkampf and

by Thomson*. Hence we may fairly assume that the supposed eyeless Articulata differ

from others of their class rather in the degree, than in the entire absence, of power of
appreciating light.

XIX. The Natural History, Anatomy, and Development of Meloé (continued).
By GEORGE Newport, Esq., F.R.S., F.L.S. Fe. ge.

THIRD MEMOIR.

The External Anatomy of the Larva of Meloë in its Relation to the Laws of Development.

Read November 2nd, 1847.

HAVING traced the natural history of Meloé, in the preceding Memoirs, I shall now
examine its anatomy, with reference to those principles which regulate the formation of
animal bodies, and which seem to be the links of connexion which associate peculiarities
of instinct with the evolution, and with the functions of special structures, —commencing
this with the ANATOMY OF THE TEGUMENT.

1. The Tegument of the young Larva.

The tegument, the parietal tissue of the body, little important as it may seem to be
when cursorily examined in the adult Vertebrata, is nevertheless, in a physiological point
of view, both in the vertebrated and in the invertebrated animal, the primary and essential
foundation-structure of the organized being. Like the earlier tissues of plants, it is at first
composed entirely of nucleated cells. It is derived immediately from a delicate, transparent
layer of semifluid cells which constitute the blastodermic envelope that is formed around
one portion of the yelk shortly after the disappearance of the embryo vesicle in the ovum,
subsequent to impregnation. This has already been shown in the brief outline of the course
of development, and in the delineations which I have given of the ovum of that “ atomie"
of creation, Stylops* ; and I shall hereafter have to show that the same general laws which
govern the development of that atomic existence regulate equally that of Heloë and of
Man. This blastodermic layer of cells, folded on itself, and partially inclosing the yelk, is
the structure from which the whole of the organized parts of the body concerned in the
voluntary functions of the animal, are immediately derived; and, as embryologists are
aware, it is to the foldings, the intus-susceptions, the extension or the shortening of
portions of this structure that the primary form of the animal body is entirely due;
whether it be that of the uniform and simply articulated worm, or of the rudimentary
embryo of the most perfect of organized beings, Man.

_ The principles which thus regulate the ultimate form of the embryo that is to be, and

the origination of its future limbs, ere it has any definite structural existence, regulate

also the whole of its growth and metamorphoses, whether these are gradual, uniform, and

uninterruptedly continuous to their end, as in most of the Vertebrata, or whether they
are marked by more rapid and extensive evolutions at some periods than at others, as in

* Linnean Transactions, vol. xx. p. 337. t. 14. f. 23-32.

many of the Invertebrata, and of which the subject of our present inquiry, Meloe, is a
striking exemplification.

It is in the tegument itself that every change of form in the external parts of the
body is commenced ; first in slight reduplications of this tissue to form segments ; next in
the aggregation or partial coalescence of these into particular sets, or regions; and lastly
in the hypertrophy or excessive growth of the tegument, at definite points, which produces
elevations or protrusions from the uniform surface, and which protrusions constitute the
origin of the future appendages. It is by the continuation of these processes of growth
in the formation of the animal,—and which processes take place by means of the enlarge-
ment and repeated fissiparous division of the nuclei of the cells of which the whole tissue is
originally composed, and by the further development of these into cells, as I shall elsewhere
show,—that the entire growth of the tegument, from the earliest period of its formation in
the ovum to its completion in the adult animal, is effected. Portions of this tissue, consoli-
dated by changes which ensue in the function of the nuclei of some of the layers of cells,
constitute the hardened dermo-skeleton, which protects and gives support to the internal
structures of the insect. The nuclei of these cells, instead of continuing to be multiplied
by repeated subdivision into separate organisms, which in their turn are evolved into cells,
seem more and more to lose their juvenescence, or reproductive power, in proportion as
they are made to approach the exterior of the body by the growth of other layers of cells
beneath them. They then gradually become altered in function, and the forces of growth
being diminished in a ratio inverse to their maturity, earthy constituents are secreted
by them in greater proportion than during their previous existence as reproductive bodies.
These earthy constituents assume an inorganic, granular, or semi-crystalline form, and
constitute the solid material of the hardened skeleton. This process takes place to a greater
or less extent throughout the whole period of development of the insect. It commences
in some parts even at an early period of the embryo in the ovum, in the solidification of
the hard portions of the mandibles. It is this result of change in the function of the
nuclei in their full age, and the partial aggregation of their granular contents, which lead
to the deciduation of layers of the tegument in the larva. The cells with accumulated
earthy matter in their interior cease to be nourished, perish, and become separated from the
as of Juvenescent: cells beneath them in the vigour of growth; and are ruptured and

own off as an entire covering when they retard the further expansion of these and of
the whole body. The deciduated cells do not differ, other than in these circumstances,
from those which are still in the course of enlargement.

bony matter,” and as analogous in development as in function to that of the external
skeleton of Chelonian reptiles. This view of its nature has recently been greatly strength-
ened by the discovery by Platner* of star-shaped corpuscles in the tegument of the Silk-
worm, very similar to those which have been described by Purkinje, Miescher, Balyt,
and others in true bone.

The consolidation of the exterior tegument in insects by the deposition of earthy
materials in its tissue, thus appears to be a vital process precisely homologous with that
of the formation of bone in the Vertebrata; first by the secretion and deposition of
granular, earthy, crystalline matter by the nuclei and nucleoli of cells; and next by the
more complete calcification of these cells in layers which form one solid envelope. This
process, deposition in layers, is recognized by the best observers, Hunter, Flourens, Goodsir,
Sharpey, Tomes and others, as the mode in which the bones of Vertebrata are increased
in diameter, through the agency of their periosteum, and not by the preparatory process
of the formation and absorption of gelatinous cartilage cells, as in their first develop-
ment in the foetus. According to the experience of these physiologists, the bones of
Vertebrata grow by the repeated deposition of layers of bony matter on their external
surface, formed by the progressive calcification of layers of cells from the inner surface of
the periosteum with which the bone is covered, as the woody fibre of exogenous trees is
formed, by their bark. The formation and growth of new bony matter in the skeleton of
Vertebrata, and the solidification of the tegument and of its internal processes in insects,
seem thus to be results which differ in these two divisions of animals only in degree, and
in the relative position of the structures in which they occur, and not in their actual
nature. In the Invertebrata, as in the Vertebrata, solidification is effected by deposition
in layers. The dermo-skeleton of the Articulata is endogenous, whilst true bone is exo-
genous in its mode of growth. Yet the process in both is as identical in principle as that
of the formation of woody fibre in the two divisions of the vegetable kingdom. The
solidification of the dermo-skeleton is carried to a greater or less extent in different parts
of the body, and at different periods of the life of the insect. In the larva, when the
formative energies are the most active, and the whole body is in a state of rapid growth,
only the exterior layers of cells become partially calcified, by the deposition of a few
earthy granules by the nuclei, exactly as the primary osseous deposits are known to take
place in the Vertebrata. But when the growth of the body begins to be arrested, prepara-
tory to an extensive change to the form of nymph or chrysalis, a greater number of cells
become calcified, and the cast-off portion of the tegument is in consequence of greater
thickness. Before the change to the perfect insect takes place, not only do more layers of
cells become altered, but fibrous tissue also appears to be developed in the most internal
layers, intermingled with the osteogenic ; and the two, becoming firmly solidified together,
thus form the insect skeleton, derived from, and inseparably connected with its dermal
tissues. This perhaps may explain the cause of the inseparableness of the fibrous attach-

ments of some of the muscles to solidified internal processes in the perfect insect, some

of which, as we shall find, are formed by actual reduplications of the hardened tegument.

The whole covering of the body in the Articulata may thus be regarded as analogous in -

its mode of development, and in its function, to true bone; and even as homologous with
the external bony skeleton of Chelonian reptiles; the internal portions of which are similar
in structure, as in office, to the internal processes of the tegument in the Articulata.

But if, for the moment, in deference to the opinions of some physiologists, we were to
discard this view of the nature of the tegument, and regard it simply as a dermal covering,
we must still look upon it as but one structure, formed of layers of cells in different stages
of growth; and not as composed of distinct tissues, epidermis, mucous layer, and corium,
the definite limits of which it is perhaps impossible satisfactorily to indicate.

When a very young Meloe (Tas. XX. fig. 1) is examined a few days after it has left the
egg, its tegument affords a complete demonstration of celleeform structure. The whole tis-
sue, if examined under a high power, is then seen to be composed of a uniform layer of
irregularly hexagonal cells (fig. 4), which are almost equally distinct in the covering of the
head itself as in that of the thoracic or the abdominal segments. In some parts of the tis-
sue, as in the more transparent ones néar the spiracles (fig. 5), each cell is seen to contain
a very delicate, granular, irregularly stellate nucleus, which I regard as corresponding to
the cells seen by Platner in the tegument of the Silk-worm. Those cells which are on the
surface of the body are of a somewhat quadrangular form, and they are arranged in a
more linear direction than those which are deeper seated. Their nuclei are distinctly
granulous, and occupy a very large proportion of the interior of the cells. This granular
condition of the nuclei exists more especially in the cells of the thoracic segments, and
closely resembles that in which, according to Mr. Tomes, true osseous matter is depo-
sited in the Vertebrata. The largest of these cells measures about one two-thousandth of
an inch in diameter. The cells in the tegument of the limbs are less uniform in structure
than those of the body. On the femora they are slightly tuberculous, so that the limbs -
are a little roughened on their surface; while on the tibial and tarsal ‘portions they are
more elongated and are less distinct. This also is their condition in the antennee (fig. 6).

The tegument has its own proper appendages in the form of hairs or imperfect spines
(fig. 7). Hach of these spines projects from the surface of what, at first sight, appears to
be a distinct opening in the external layer, but which is an enlarged and altered cell,
the size of which, sometimes, is much greater than that of the other cells, and measures
nearly one thousandth of an inch. It is circular, with a convex disc, bounded by a distinct
margin, and surrounded by the proper cells of the external surface. In its centre is a
slight elevation, from which passes out the minute hair or spine, perfectly smooth on its
sides, and gradually diminishing in size from its base to its apex. When closely examined
each spine is found to be hollow from one extremity to the other. From its central ori-
gination, in a distinct structure homologous with that of the other cells of the tegument,
I am induced to regard the spine, as, primarily, an excessive growth of the nucleus of a
cell, everted and developed outwards as a single structure instead of being subdivided into
nucleoli, or of secreting earthy matter, as in other instances, its cavity being continuous
with a passage in the layers of cells beneath.

envelope around the nucleus within an adult cell, and this is followed by the fissiparous
division of the nucleus itself into two bodies, which, subsequently enlarging, have each
their own proper cell-wall formed around them; after which the cell-wall of the parent
structure disappears, and leaves the young nuclei free to be developed into separate cells,
like that from which they have originated. Thus the end of the development of a forma-
tive cell is the fissiparous division of its nucleus. This mode of development of the tegu-
ment in the young animal, after it has left the egg, is confirmatory of the theory of
Schwann with reference to that of the general tissues; and it also accords with the views
of Kölliker respecting the division of the yelk cells in the ovum; and with original obser-
vations made by myself, to be elsewhere demonstrated, on the mode of formation of the
blastoderma. |

If a transparent portion of the surface of one of the thoracic segments of a young Meloé
which has been for some months in strong spirit, be covered with thin tale, with a little
fluid around it, and be then examined by transmitted light with a magnifying power of
four hundred and fifty diameters, we can immediately recognize the granular, nucleated
external cells of the tegument. If then we approach the lens to the object, so as to be too
near to have the external cells in focus of vision, the layer of cells beneath them is brought
into view. The cells of this deeper-seated layer are smaller than those of the outer one.
If the specimen examined has been several days from the egg, before immersion in spirit,
then these cells, instead of having each a single granulated nucleus like those of the outer
layer, are found to contain each two nuclei of equal sizes, closely approximated together,
but perfectly distinct, and inclosed in one common envelope (fig. 8). In some of the cells
the two nuclei are more separated than in others, while in those which have most
recently changed they are closely approximated. Occasionally the original nucleus of a
cell, not yet divided into two, is observed, in the commencement of its change, with a
on on one surface; but this fact ean only be seen when the exami-

fissiparous emarginati
nation happens to be made on an insect in which the tegument has not far advanced in

its changes. The fissiparous division of the nucleus thus appears to be the usual mode of
growth of all cellzeform tissues.

Although the solidified tegument supplies the place of a true skeleton in the Articulata,
it is also the agent of other functions; which are of as much importance to the welfare of
the animal physiologically, as this is anatomically. It is the medium of the transudation
of effete matters from the surface of the body, the retention of which would be detrimental
to the entire organism. The celleeform structure of the tegument enables us readily to
understand its adaptation to this office. But, besides this, it is subservient to another
function, which is equally important with that of transudation,—the aération or oxygena- -
tion of the fluids. This is effected solely by the tegument in the very young embryo in the
egg ; but as the embryo is advanced to maturity, the function is shared by, and, after birth,
is almost entirely performed by respiratory organs, which originate in, and are constantly
connected with the tegument as spiracles, or breathing orifices in the sides of the body

the very last period of the embryo in the ovum; since it is only in the latter periods of —
embryonic life, when the last portion of the yelk is inclosed in the thorax of the young
insect, and when the blood has begun to be circulated, and requires to be more exten-
sively aérated than it has already been, that organs of respiration are formed. |
It is exceedingly difficult to detect the existence of spiracles in the young Meloé even
at the moment of its leaving the egg, although formed before its escape; but at the end
of a few hours, or a day, the spiracles of the trunk become distinct, although those of
the abdomen are still exceedingly small. With a magnifying power of three hundred
diameters they may then be seen in specimens that have been preserved in spirit. There
are then ten pairs of spiracles (fig. 1 bb), one pair (fig. 9) in the meso-thoracic and
nine pairs in the abdominal segments. They are placed on the lateral margin of the
dorsal portion of the segments on each side. The first two pairs are very much the largest,
and are situated, the first in the anterior of the mesothorax, and the second in the first
of the abdominal segments, the fifth segment of the body. The remaining spiracles are
each not more than one-third the size of the three anterior ones, and are situated in the
abdominal segments, one pair in each, from the sixth to the thirteenth inclusive. j
The structure of the spiracle in relation with that of the tegument, at this period, is
exceedingly interesting. The two pairs of large spiracles (fig. 9) have a circular opening,
with a free, smooth margin, which projects from the surface, and is bounded by the edges
of the external layer of dermal cells. The orifice of the smaller abdominal spiracles (fig. 5)
is at first simply an irregular oval opening, or space between three dermal cells, bounded
also by a slightly projecting margin, and very similar in appearance to the stomata on the
surface of the leaves of plants; thus distinctly indicating, in accordance with the views of
Schleiden and Schwann, the close analogy which exists in the mode of formation of animal
and vegetable tissues. The two pairs of thoracic spiracles seem to be in a more advanced
stage of development than the abdominal, but in their internal condition the whole are very
similar. The two anterior pairs open each into a hollow, somewhat spherical cavity, or
follicle, communicating with a sinus in the granular tissue of the segment. The diameter
of the cavity is about three times that of the spiracle. It is narrowed at its bottom, and
there are faint indications-of its further extension into the body. The follicles with which
the spiracles of the abdominal segments communicate, are also much smaller than those
of the thorax, and they are less clearly defined. A follicular cavity in the granular tissue
of the body thus appears to constitute the earliest condition of the respiratory organ in the
vue Meloe, and probably also in other air-breathing Articulata; since these cavities in
Meloé are precisely similar in their general appearance to those described in my former
memoir in the very young Stylops. They also resemble in some respects the respiratory

always continuous with the external layer of the tegument, and is thrown off with it at
each change. Whether the spiral fibre of the trachea, which is in the course of formation,
originates, as believed by Platner, in the nuclei of cells, I am not prepared to affirm; but
from the existence of nuclei in those which compose the walls of these cavities, it is pro-
bable that such may be the case.

The tegument of the head affords some peculiarities of particular interest. The cells
are smaller and more uniform in size and shape than on the body and limbs, and measure
each less than one two-thousandth of an inch in diameter. But those which cover the
antennze are much larger, and are as irregular as those on the legs. The eye (fig. 10),
which, as formerly shown, is a single structure in this stage of Meloé, fitted only for
near vision, has its large projecting cornea formed entirely of layers of perfectly trans-
parent dermal cells, which are continuous with those that cover the parietes of the
head, but are somewhat smaller, and measure about one three-thousandth of an inch.
Those which form the circumference, and general surface of the cornea, are each slightly
convex, and are all of the same size, like the corneales in the compound eye of the
perfect insect *; while the centre of the cornea, the focus of the line of vision, is occupied
by a single cell, much more projecting, and more than twice as large as the others. This
condition of the cornea in the young Meloé, although perfectly distinct, is very difficult
to observe, owing to the circumstance that as yet the cells constitute only portions of one
nearly uniform transparent tegument of a single organ, and are not freely isolated, as is
the case with the corneales in the imago. It is from this cause that these presumed
embryo corneales in the larva can only be detected when the object is placed on its side,
and when a high power of the microscope is employed.

This is the condition of the external portions of the tegument.” When the young animal
has been a few days from the egg, the deeper-seated layers of cells have in part united
longitudinally, and constitute a fibro-cellzeform structure, which gives attachment internally
to the muscles ; while the external layers continue to grow and be reproduced as distinct
cells. The internal layers thus constitute the true dermo-skeleton. This may assist to
explain what I have yet to demonstrate; that the organs of support which exist in the
interior of the body in the perfect insect, strong bone-like processes, which give attach-
ment to muscles, and which in some parts support and protect the nervous centres like
the vertebræ in Chelonian reptiles, are solidified portions of the common tegument ex-
tended inwards, and consolidated during the metamorphoses of the insect.

Each segment of the dermo-skeleton in the imago, as shown by the late Professor
Audouin+, is made up of distinct pieces, the separate development of which is Put slightly
indieated in the very young larva. Some of them, however, are marked in the head and
thoracic segments. In the head a triangular suture is extended forwards in the middle
line of the dorsal surface, between the eyes, and, diverging on either side to the antenne,
marks its line of union in the ovum. The prothorax, meso-thorav, and metathorax, are
also marked by a median dorsal sulcus, indicating the original individuality of the two
sides in the embryo, and their junction after the last parts of the yelk have been received

into the prothorax. The dorsal region of the body in the young Meloé, as in the very
young larvæ of most of the Articulata, is not so far advanced in its development as the
sternal and ventral, at the period when the insect leaves the ovum; owing to its being the last
portion that is formed. Consequently we find the insertions of the legs in the young, at a
relatively greater distance from the median line of the sternal surface than in the imago.
The legs are as it were appendages of the sides of the body; while the respiratory orifices,
which properly belong to the membrane that connects the dorsal with the ventral surface
in the perfect insect, actually exist in the young Meloé at the sides of the dorsal region.
But in proportion as the growth of the body is advanced the relative dimensions and posi-
tion of these parts are changed. The growth of the sternal surface; after the insect has
left the ovum, does not proceed so rapidly, and is not carried to so great an extent as that
of the dorsal; the result of which is that the coxæ of the legs become relatively more and
more nearly approximated to the median line, and are transferred to the under surface of
the body in the perfect insect. The spiracles also, from a like cause, are changed in their
form and position, and are gradually removed from the dorsal to the lateral surface by
the more rapid growth and extension of the former. The dorsal region itself is widened,
is rendered more convex, and ultimately becomes the most voluminous portion of the
whole body. These facts of development are common to all insects, and are well-indicated
in the structure of the adult larva of Meloe, in which the entire form of the insect
is completely altered by this difference in the relative development of its parts.

2. Tegument of the Full-grown or Pseudo-larva.

Every natural change in the animal body, whether of structure, of function, or of
instinct, takes place by regular and inevitable gradations, all of which seem to depend on
immutable laws of organization. No strongly-marked transition from one condition to
another, whether in character, in form, or in degree, ever occurs by sudden or violent
alterations, without deranging the body, the organ, the function, or the instinct that is
subject to such change, and inducing its permanent impairment, or premature annihilation.

Newton, the pride of physical science, was as fully impressed with these truths, with
regard to the animal body, as with their correlatives which regulate the universe itself,
when—pondering on the laws which he was then proving govern light and space—he
wrote the following words :—* Idemque dici possit de uniformitate illà, quze est in cor-
poribus animalium * - These views with regard to the uniformity of structure and develop-
ment in organized beings,—originally glanced at by Malpighi in his anatomy of the Silk-
worm in 1669, and dwelt on to some extent by our own almost forgotten countryman
Dr. Willis, in 16821,—have since been amply demonstrated by the illustrious Geoffroy Saint
Hilaire$ and his numerous followers; and it is now my humble endeavour still further to

exemplify them, together with the views of Schwann on the formation of tissues, in the
Anatomy of Meloe, and to apply the principles on which they are based to the functions
also of animated existence, in illustration of their dependence on special structure.

It is the great principle of gradational development which operates so markedly in the
organization and habits of many of the Articulata, and which causes them, as we have
already seen in Stylops and Meloé, to differ so greatly in every respect in their young and in
their adult states. In each of these, the general conformation of body, and of each particular
organ, seems to have reference to some speciality of structure or of habit; but,—owing to
our imperfect knowledge,—as who will presume to say, in denial of this view, that he is cog-
nizant of all the facts in the natural history of even one species of animal ?—the object or
applicability of every variation of structure is not always readily traceable in its details of
colour, of armature, of size, or even in the minutis of form, although invariably evident in
general design. We have seen this in the structure of the mandible, in the condition of the
eye, in the size and power of the limbs, in the peculiarities of their tarsi (fig. 12), in the acute-
ness of the physical senses, and in the vivacity of the movements of the young Meloe in its
incipient parasitism ; and also like, but less needed, and consequently less marked conditions
in Stylops. In both we have seen that gradational changes begin to be effected in the organi-
zation ofthe animal immediately the physical conditions in which it is placed are altered; and
that these changes commence in its tegument. The Stylops larva, covered with its arma-
ture of spines, penetrates insidiously into the body of the Bee, and, engorged with nutritious
and stimulating juices, increases rapidly in bulk, casts its embryo covering, and from an
active becomes an almost quiescent being. Its elongated limbs are atrophied and reduced
to mere tubercles. The spines that arm the margins of its segments,—doubtless, designed
by creative Omnipotence to aid it in forcing its way into the body of the bee-larva,—as the
spines on the pupa-case of the Cossus assist that insect in its transit to the outlet of its
burrow in the trunk of the Willow, and enable it to force its way through its strong
silken cocoon, preparatory to its liberation as a Moth,—then become utterly useless to
the young Stylops, are entirely thrown off at its change of tegument. In like manner,
Meloé, most active immediately after it has left the egg, and when designed to attach
itself to the irritable Bee for conveyance to its nest, gradually becomes, after it is lo-
cated and nourished there, the heavy apodal pseudo-larva. The structure of its tegument
then undergoes considerable change. The forces of growth in this tissue, centred in the
nuclei of its cells, and the repeated division and development of these into constituent
producing portions of the whole, seem gradually to become less and less energetic at each
change of tegument, the intervals of which are progressively extended. When reproduc-
tion in these constituents is long retarded, throughout the whole or chief portion of them,
their arrest seems to limit the entire bulk and form of the being in that stage of its exis
ence, and new series of changes are induced. But when growth proceeds less rapidly in
some of them than in others, the form of the entire body, or of some particular region of it,
is changed. The tegument of the pseudo-larva, and that which the adult larva throws off
on assuming this condition, afford ample demonstration of this view. The body of the larva,
altered from that of the slender, agile little being, with elongated limbs, and long caudal

styles, as when it left the egg, to the heavy, fat, convex grub (fig. 13), has been changed in
242

176 MR. NEWPORT ON THE NATURAL HISTORY, ANATOMY,

its form by almost imperceptible individual differences in the development of the nuclei of
the multitudes of cells of which its tegument is originally composed. The greater rapidity
of growth in those of the dorsal region has occasioned the enlargement of that portion of
the body to an extent far beyond that of the region which is first formed in the production
of the embryo in the egg—the ventral surface—and the entire body, as a consequence, has
gradually assumed a totally different outline. This primary change in one region leads to
secondary changes in another, more especially in its appendages. We have an instance of
this in the gradual reduction of the legs to tubereles, their enlargement, even during the
feeding state of the larva, not having kept pace with that of the dorsal region; whilst at
the period of change to the pseudo-larva (fig. 18), the rapid growth of this region of the body
not only most powerfully arrests their further development for a time, but actually con-
duces to a state of atrophy, as shown in their diminished size, and in the complete decidua-
tion of their terminal armature, the trifid prehensile claws, which we know are so important
to the larva in its earliest condition. This effect of rapid growth in the dorsal region is evident
not only in Meloë but in all larvæ that undergo similar metamorphoses, Curculio, Antho-
phora, Ophion, and other genera. It is not the result of exhaustion of the forces of growth
in the undeveloped parts, but only of their retardation, the consequence of excessive deve-
lopment in others. In these views I refer only to the primary and essential means of de-
velopment in the tissues themselves, and not to those secondary ones, which are presently

to be examined, and by which the body of the insect is made to assume the imago form.
The principle which operates in the deciduation of the claws, operates equally with
reference to the caudal styles (fig. 1 d), which have the same mode of origin as the per-
manent appendages of the segments, the limbs, of which they are the true homologues.
The dermal appendages, spines, hairs, and scales, are similar in their mode of origin to the
appendages of segments, but are not homologous with them. The latter always originate
by an extension outwards of an entire portion of the tegument of a segment; while
hairs, spines, and scales originate in the nuclei of the cells of separate layers of tegument.
I have detected this origin of hairs in the embryo before it leaves the ovum. Hairs and
scales are developed from the more superficial layers of cells, while spines may extend
from the more deeply seated. Essentially their origin is the same. In like manner, when
either cease to be nourished, their function in the economy is at an end, they become atro-
phied, and are thrown off with the cast portion of tegument. This is the case alike with -
the caudal styles and lateral hairs of Meloe, with the styles and marginal spines in Sty-
ops, and with the enlarged branched spines on the larvæ of many Lepidoptera, changes
which are the result of other more important ones in the organization of the animal.
Function thus is the result of special structure. During the persistence of these organs
bay. are nourished as fully as other structures, and it is only when this nourishment is
diminished or withheld that they become atrophied. In many instances, as in the caudal
styles of Meloé and Stylops, and the spines in Lepidoptera, the parts involve a large por-

més p ida d s cavıty of = body, as in Lepidoptera and Crustacea. In these
ir tons A et ip in a single cell in the embryo, gradually involves
ow it in its growth, until from a single part it has become

AND DEVELOPMENT OF MELOE. 177

a multiple of parts, which are thrown off and reproduced like the cast tegument itself,
until causes are induced which occasion its atrophy and decay. These causes rarely occur
in the Crustacea, which do not materially change their form after the earlier periods of
life. Hence the tegumentary appendages are usually retained in this Class as permanent
structures: but when secondary causes of development and change of form are in operation,
as in the metamorphoses of insects, then these appendages also, like the simpler dermal
hairs, are deciduated. The communication of the spines, in the Crustacea, by their tubular
cavity, with the interior surface of the tegument, as shown by a recent French observer,
M. Lavalle*, proves that the spine may be an eversion and extension outwards of the
whole tissue; but it does not prove, as M. Lavalle seems to think, that this is its original
condition, but only that it may become this in the course of its growth as a spine. That
this is the correct explanation, and that hairs, and also scales, originate primarily in
the nuclei of single layers of tegument, seems proved by the fact that the skin of the
full-grown larva of Meloë is covered in every part with extremely minute spiniform hairs,
which are scarcely as much as one-thousandth of an inch in length (fig. 14). "These hairs
proceed each from the centre of the cells which form the layer of tegument cast by the
insect on assuming the pseudo-larva state. These minute hairs are hollow at their base,
like the larger ones, and are simple eversions of the nuclei of the cells of that layer of
tegument; and this also is the anatomical condition of scales. "That this is the fact is
proved by the circumstance that not the slightest trace of these microscopic nucleus-born
hairs remains in the tegument of the pseudo-larva of Meloé. Still further proof is derived
from the facts connected with the atrophy of the spines at the last change of tegument
of the larvæ of Lepidoptera. In these larve the spines, which previously communicate
in their interior with the deep-seated layers of tegument, have their nourishment cut
off, and their function in the economy destroyed, by the growth and enlargement of cells
in their interior, extended at their base from the deeper-seated layers of tegument; so
that, on the change of the larva to a chrysalis, small tubercles only remain on the tegu-
ment in places previously occupied by elongated and powerful spines.

It is in this way that not only hairs and spines, but also the armature of the distal ex-
tremities of the limbs, the claws, are thrown off, and the limbs themselves become atro-
phied, by deciduation of their external covering, from without inwards, as well as by
actual retardation of growth: both of these results are induced to a greater or less extent
in proportion as other parts or regions are enlarged.

These are some of the primary laws of the organization and growth of structure, the
formation of which, thus commenced, is further advanced by secondary ones ; and develop-
ment is hastened or retarded by the operation of physical conditions,—light, heat, food,

and all material influences.

To pass now from the primary stages of growth and change to the secondary, by which
further development is effected, we must first examine the structure of the layer of tegu-
ment which the full-grown larva throws off on assuming that state in which alone I have
hitherto found this insect —the pseudo-larva. This cast portion always partially envelopes

178 MR. NEWPORT ON THE NATURAL HISTORY, ANATOMY,

the inferior and posterior parts of the body of the pseudo-larva, thrust backwards in a
packet, as it is slipped off at the period of change. In the absence of discovery of the larva
itself, before it is full grown, this cast skin enables us to indicate its general form and
economy, at that period of its existence, as surely as the fossil bone enables the compa-
rative anatomist of the Vertebrata to indicate those of the habitant of a former world.
The skin of the larva is fissured at the period of change along the median line of the pro-
thoracic segment, and is extended forwards to the head and backwards to the meso- and
meta-thoracic segments, exactly as in other insects. By carefully removing this skin from
the pseudo-larva, and relaxing it in water for some hours, and then inflating it gently with
a blowpipe, the general form of the larva is made apparent. It is a fat, yellow-coloured,
elongated grub, with six short legs, formed of short coxal, femoral and tibial joints, covered
with delicate scattered hairs, and with tarsi, each of which is a single joint, armed with a
single short strong horny claw. The tarsal spines which exist in the very young Meloe on
each side of this claw,—and which are of so much importance to the insect at that period
of its existence in enabling it to cling firmly to its victim, and, relatively with other parts,
are so large and conspicuous, that Léon Dufour derived from them the character of his -
genus Triungulinus,—have entirely disappeared at previous changes of the tegument. In
like manner also the caudal styles have been removed, being reduced to mere pointed
tubercles, as in the larva of Cryptophagus*, preparatory to their complete obliteration in
the pseudo-larva. The body is arched, slightly convex, and formed of fourteen segments,
with a few scattered elongated hairs, as in the very young state; and also, as I have
already mentioned, is covered on every part with multitudes of microscopic ones, scarcely
one-thousandth of an inch in length, each proceeding directly from the centre of nearly
every cell in this cast envelope. The segments of the body are nearly all of the same
dimensions, and thus give to the larva a more uniform and less articulated appearance
than that which it presents in its earliest state, when the segments of the thorax greatly
preponderate. |

The external organs of respiration have undergone but little change, éither in form or
in situation ; excepting only that the second pair of spiracles are now of the same size as
those of other segments. The small size of the whole, relatively to that of the body, seems
to indicate a minimum degree of activity in the function of respiration, and consequently
a sluggish mode of life, similar to that of the Bee-larva, in the abode of which the Meloé

protected by a raised horny margin. Internally they are lined by a membrane made up
of extremely minute but distinct cells, which form a layer that is continuous with the

This cast envelope of the full-grown larva shows that, up to this time, the head has

undergone but little alteration in form from that of the very young, like which it is
marked with a longitudinal and a triangular sulcus. The eye, which in the embryo
larva is a single organ, is now a compound one, formed of three facets on each side of the
head. In this multiplication of parts it resembles the eye in the lower Myriapoda, the
Julide, in which the eye, commencing as a single structure, becomes at its first change a
triple one*, preparatory to future subdivision to form the compound eye of the imago. Up
to this period the antenna has undergone less change than any other structure of the
head, thus proving that, whatever is its function, it is exereised in preeisely the same
manner in the adult as in the very young larva. But it is in the parts of the mouth that
the greatest changes of form have occurred ; changes which lead us to infer a change in its
economy. The mandible of the adult larva, as I have formerly stated, is a short strong
corneous organ, totally different from that of the embryo larva. It is in this that the
mode of development by anchylosis, or complete union of originally separate parts, in the
formation of one structure or body, is most distinctly shown. The mandible in the ori-
ginal formation of the embryo in the egg is the true and legitimate appendage of, at least,
one of the basilar segments of which the entire head is composed, and which segment is
identical in its mode of origin with the other segments of the body. This fact I had the
honour of announcing in the * Transactions’ of this Society, as discovered in the embryo of
Geophilust; and although it has been somewhat questioned by Prof. Erichson}, I have
since been enabled to verify it repeatedly, not only in the Myriapoda, but also in the
embryos of true insects—for example, in. orficula. To trace the formation of the man-
dible, therefore, we must regard it as the articulated appendage of a single segment,—in
fact, a true limb in its origin and structure, but which, gradually altered in its condition
and form, becomes adapted to a particular function, and to variations in the mode of its
employment in that function. The changes in this structure usually take place in ani-
mals at so early a period, often, as in the whole of the Vertebrata, even during the earliest
stages of the embryo, that we are unable to follow them, and satisfy ourselves of the fact
of their occurrence. But this is not the case in the lower forms of Articulata, the Myri-
apoda, nor even in Meloé and many other hexapods. In the embryo of the vermiform
Myriapoda, as in Geophilus, every segment of the body is furnished with a pair of append-
ages, and this also is the case with each of the segments of the head. These appendages
originate at the sides of each segment as minute tubercles, one pair to each. Those which
belong to the head appear first, but are followed in quick succession by those of the
anterior segments of the body, and sooner in proportion to their proximity to the head.
No difference is at first recognizable in any of them, either in form or size; but after a
period more or less brief, according to the type and species of animal, the mandible
becomes enlarged and changed in its appearance. In the Chilopodous Myriapoda it retains
the articulated pediform structure throughout the entire life of the animal, and is em-
ployed as an organ of prehension rather than of manducation. This is precisely what we
have already seen in the very young Meloe, which has a mandible jointed and pediform in
structure, and penetrant and prehensile in function. The structure of an organ thus indi-

cates the purpose for which it is employed; and the habits of the Meloe larva, and its
mode of seizing and attempting to pierce the skin of the bee that conveys it to its nest,
confirm the conclusion deduced from the structure of its mandible.

The gradual change of form which the mandible undergoes in the larva state, indicates
some modification of function even during the larva period. I have already shown that the
mandible in the adult larva is a short thickened corneous organ, more nearly resembling
that of the perfect insect: not as in that fitted for cutting and comminuting vegetable
tissue, nor, as in the very young, for piercing soft textures, but rather adapted for crush-
. ing and bruising. The mode in which this organ is changed in its condition is, first, by
deciduation, at the change of tegument, of its terminal claw-like apex, exactly as the cor-
responding part of a true limb is thrown off at the change on the reduction of the legs to
mere tubercles, preparatory to their future re-development in the nymph or pupa in a new
form; next, by the growth and enlargement of every part of the structure in.a lateral,
and its retardation in an axial direction. The result of this change is a complete obliteration
and anchylosis, or permanent union of the whole in one powerful angulated structure,
which retains an articulation only with its parent segment. This is the mandible of the
adult larva. |

Changes, similar in principle and mode of operation, but carried to a far less extent,
take place in the other appendages of the cephalic segments of Meloé, the maxille and
palpi, the function of which, like the structure, undergoes but little modification.

The whole of the feeding-period of the larva state, in so far as refers to change in the
segments of the body, is scarcely other than one of simple growth and enlargement.
Change of form by aggregative development, as we have seen, commences in the append-
ages and parts of the head; but the tegument of the segments in the larva still retains
its original flexible uniform condition, and is scarcely thrown into folds, even at the junc-
tion of separate segments. The nuclei of its component cells continue to reproduce, and
when the external layer becomes aged and resistant, obstructing the function of the in-
ternal, it ceases to be nourished and is removed. But as the entire body advances to its
maximum of size, certain forces become active in its internal structures, which lead to those
rapid and important changes of form in the whole which we recognise as the Metamor-
phoses of the Insect. |

Those structures which are the immediate agents of all voluntary and instinctive move-
ments, the muscles, are also those of the Metamorphoses. Nourished to the utmost while

organized matter: we only know, of a certainty, that it is by the agency of the con-
tractile muscles that the form of the body is rapidly altered at the period of metamorphosis,
and that whatever is the origin or the nature of the contractile power, its evolution is
accelerated or retarded by physical influences. Alternations of heat and cold, drought and
“* moisture, are favourable to the changes which this power effects, and promote their occur-
rence, as an unaltered continuance of either of the conditions mentioned retards them.
Reaumur found that by keeping chrysalids of the common white butterfly in an ice-house,
the changes to the perfect insect were prevented for two years; whilst by removing others
in the depth of winter to a hot-house, he induced the appearance of the perfect insects in
a few days. I have myself noticed similar facts in the Hymenoptera. Some larvæ of
Anthophora, which I collected in the month of October, and preserved in a warm room
through the winter, instead of undergoing transformation, as in their natural haunts, on
the accession of warmth, in February and March, did not change into nymphs until some
hot days in August, when the temperature of the apartment was greatly increased ; and
having entered the imago state in a few days afterwards, then lapsed into perfect quiescence,
-or sleep, as in their natural state of hybernation, and did not become active until the fol-
lowing spring *. Thus alternations of condition are essential to the changes in growth
and development, as to the health of the body, and to the evolution of all vital power.
This is equally true with reference to the highest, as to the lowest of created beings; to
the most perfect, as to the least organized ; to ourselves, as to the insect we are examining.
Influenced by alternations of condition in the functions of respiration and nutrition, the
muscles of the insect acquire an accumulation of contractile power before the change;
and when the larva has attained its full size, and its further growth is arrested, the moment
of transformation has arrived, and this power in the muscles constitutes the secondary
and most evident means of development. Certain muscles in the insect are ranged in the
axis of its body, in a longitudinal direction, attached to the internal surface of the tegu-
ment in parallel series at the anterior margin of one segment, and extended to the poste-
rior of another; and others are ranged in diagonal, or in transverse series. By the action
of the longitudinal ones, aided by the diagonal, and operating on the whole structure, the
main portion of the tegument is gradually separated from the worn-out external layer that
is to be removed; and by a concentration as it were of the muscular forces in the seg-
ments immediately behind the head, this layer is ruptured along the dorsal surface; and,
gradually detached from the new covering beneath it, it is slipped off backwards by suc-
cessive contractions and elongations of the segments.
When this change takes place after the insect has acquired its full growth as a larva,

* Since this paper was read I have repeated this observation. Some specimens of Anthophora obtained in the larva
state on the 12th of September 1847, were preserved in a room of moderate temperature during the winter; but they
did not change to nymphs until from the 7th to the 14th of July 1848, and then only assumed the perfect state in
September of the same year; after which they did not throw off the last tegument until January 1849, and became
active imagos in February. I pointed out this fact of arrested development, at a uniform high temperature, at a
Meeting of the Entomological Society in April 1847. (See Trans. Ent. Soc. vol. v. pt. 2, 1847, p. xi.) I may men-
tion also that five of the larvæ which were the subjects of this experiment, were of a deep yellow instead of a white
colour, and that two of them produced male, and three female imagos, so that difference of colour has no reference to
‘the sex of the individuals.

and has ceased to feed, as at the period at which I have found the full-grown JMeloé, the
muscles effect a complete alteration in the segments both relatively and individually. The
abdominal segments, which are the largest while the larva is feeding, are quickly reduced
in size when fresh nourishment has ceased to be supplied; while those of the thorax are
enlarged, and duplicatures of tegument are formed between each by the shortening of the*
longitudinal and diagonal muscles.

In the pseudo-larva of Meloe (fig. 13) these changes have only commenced ; but when the
insect passes to the nymph or pupa state (fig. 15), the alteration is carried to a very great
extent. The longitudinal muscles of the abdominal segments occasion, by their powerful
contraction, broad reduplications of the tegument, the posterior margin of one segment is
made to cover the anterior of the one next behind it, and the whole are much shortened.
The force of development in this region is from behind forwards, the effect of which is to
occasion a rapid enlargement of the head and of the thoracic segments, and the coalescence
of some of the latter by aggregation and anchylosis. This is carried to the greatest extent
in the segments of the middle of the body, which form the union of the thorax and abdomen
in the imago. In some insects the fifth segment of the larva is reduced to its minimum,
and disappears as a sectional portion of the animal, its rudiments only being left. In the
nymph or pupa of Meloe the metathoracic or fourth segment is the shortest, the fifth being
further shortened at the next change.

The immediate result of the altered proportions of the abdominal segments, and their
removal forwards by the action of the muscles on the tegument, is a re-induction of the
forces of growth in the appendages of the thoracic and cephalic segments, and a conse-
quent enlargement of the segments themselves, more especially those of the head. This
region in Meloe is enormously enlarged, as compared with the head of the larva. But
this does not result, as M. Ratzeburg seems to think, from certain observations he has
made on Hymenoptera, from a coalescence of the head of the larva with the segment next
behind it, but it is entirely due to the rapid growth and expansion of all parts of the head
at the period of transformation.

The change effected while the larva is passing to the pseudo-larva state, is a com-
mencement of a re-induction of the growth of the appendages of the head and thorax.
The legs, then reduced to tubercles, are soon redeveloped beneath the tegument of the
pseudo-larva in an entirely new form, with jointed tarsi, ready to be elongated at the
instant of change to the nymph.

In addition’ to the redevelopment of these parts, the rudiments of new organs are pro-
duced. The internal respiratory structures are extensively affected by the changes, as is
the case in all insects on becoming pup:e, and the result is to occasion the expansion of a

tions, changes which constitute it the true skeleton of the insect. The alterations which
the body undergoes in form are not accidental results of the actions of the muscles,
but depend in each species on definite unvarying geometrical principles of force and rela-
tion. Portions of the tegument which give attachment to muscles are folded inwards in
the head and thorax, and becoming solidified constitute a rudimentary internal skeleton,
some parts of which merely give attachment to muscles, whilst others, as in the Verte-
brata, inclose and protect the nervous system. These I shall hereafter examine with the
dermo-skeleton of the imago.

XX. Notes on the Vegetation of Buenos Ayres and the neighbouring districts.
By CHARLES JAMES Fox BUNBURY, Esq., F.R.S., F.L.S. $c.

Read March 1, 15, and May 3, 1853.

THE principal materials of the following notes are derived from the very extensive
botanical collections of the late Mr. Fox, formerly British Minister at Buenos Ayres, and
afterwards at Rio de Janeiro. The herbarium formed by Mr. Fox in the neighbourhood
of the former city, as well as at Monte Video, Maldonado, and other localities on the
northern shore of the Rio de la Plata, and along the lower part of the river Uruguay,
during the years 1831, 1832 and 1833, is so considerable, that I am inclined to think it
may be viewed as representing a great part of the vegetation of those countries, and may
afford sufficient ground for the remarks which I propose to make on its leading charac-
teristics. In a residence of about a month at Buenos Ayres, in the beginning of 1834, I
had myself the opportunity of becoming acquainted with the most prominent features
and general aspect of the vegetation. The principal published works from which I have
derived assistance, are M. Auguste de Saint Hilaire’s Report of his Travels in Southern
Brazil (published in the Mémoires du Muséum, vol. ix.), and the papers by Sir William
Hooker and Dr. Walker-Arnott on the plants of Extra-tropical South America, in the
* Botanical Miscellany ’ and ‘Journal of Botany. I am indebted to Sir W. Hooker also
for very important assistance in naming the species contained in Mr. Fox’s collection.

The region of which I propose chiefly to treat, is that lying on both banks of the Rio
. de la Plata, and on the lower part of the courses of the two great rivers by whose junc-
tion it is formed; comprising consequently those parts of the republics of Buenos Ayres
and Banda Oriental which lie nearest to the Plata, between the parallels of 33° and 35°
S. lat. The collections before me were formed in the neighbourhood of the coast and of
the rivers, so that I am obliged to rely upon other authorities for the botanical cnarac-
teristics of the interior of those countries, in which, indeed, according to such information
as I can procure, a considerable degree of uniformity seems to prevail. I shall introduce
also some remarks on the vegetation of the southernmost part of Brazil, a district in
which Mr. Fox made large collections, and which forms a connecting link, botanically as
well as geographically, between the country I chiefly treat of, and the tropical parts of
the same continent.

The Rio de la Plata, which, even as far up as Buenos Ayres, is between twenty and
thirty miles wide, forms a strongly marked geological boundary, separating two widely
extended and very dissimilar formations. All its northern shore is composed of crystal-
line rocks,—granite and gneiss, and their various modifications,—which range from thence
to the northward, uninterruptedly, through many degrees of latitude, constituting the
whole coast of Brazil to far within the tropic; it is said, even to Bahia. On the south of

the great river, nothing is seen but tertiary formations of a very late date: first, the mud
and marl of the Pampas, and further south, the gravel and shingle of Patagonia. So
absolute is the line of demarcation, that, while on the northern bank of the river the
granitic rock is perpetually showing itself on the surface in low rocks and hillocks, on
the south bank not a stone nor a pebble is to be found, and all the stone used at Buenos
Ayres, for paving and other purposes, is brought from across the river. But, notwith-
standing this remarkable difference in the geological structure of its two banks, the Plata
does not form a botanical boundary-line. There are indeed several species of plants
which are confined to one or the other side, and some families, principally tropical, which
do not cross it; yet the leading characteristics of the vegetation, both as to its general
physiognomy and its prevailing forms, are the same on both sides. The whole country,
therefore, from the frontier of Brazil southward, as far as the Pampas vegetation extends
(or to the border of Patagonia), may be considered as one botanical province, which, for
the sake of convenience, I shall provisionally call the Argentine Region, from the name
of the great river.

The botanical characteristics of this region are well marked. The most striking pecu-
liarity of its physiognomy is the almost entire absence of trees, and the scarcity even of
shrubs, except along the banks of the principal rivers. Every one who has come from
Rio de Janeiro to Monte Video and Buenos Ayres has been struck with the contrast
between the gigantie vegetation of Brazil, and the bare, treeless, almost barren character
of the shores of the Plata, where the cultivated poplars, and the flower-stems of the
Agave, and here and there a solitary Ombi tree (Phytolacca dioica), are the only objects
that relieve the. nakedness of the country. Yet the vegetation along the river-side, at
least near Buenos Ayres; may almost be. called luxuriant in comparison with that at a
short distance inland. It is not that the vegetable covering of the soil is really scanty or
meagre, but the vast majority of the plants which compose it are herbaceous, of low
growth, and for the most part not very conspieuous. This treeless character of the
country has been forcibly described, and its possible causes most ably discussed, by
Mr. Darwin, in his ‘Journal. The immediate banks of the Uruguay and the Parana,
however, and the islands in those rivers appear to be wooded, though not with trees of
great height or size. | |

As compared with the vegetation of Brazil, that of the Argentine region is distinguished
not only by the predominance of herbaceous plants, but.(as might be expected) by the
diminished numbers of tropical families, and also by something of a more European phy-
siognomy. I cannot, however, think that this resemblance of the Argentine to the Euro-
pean flora is as great as it has been represented by some celebrated botanists. The re-
semblance appears to me partly fallacious, occasioned by the abundance of naturalized
European plants ; and, excluding these, to consist rather in a certain general similarity
of outward appearance than in a real botanical analogy. |
à "XD (as quoted by Meyen in his : Geography of Flants,’) says that, “out of

ch belong to Buenos Ayres, 70 appear in Europe;” and St. Hilaire, a

very high authority, states that, of 500 species collected by him in the Banda Oriental,

between the mouth of the Plata and that of the Rio Negro, a tributary of the Uruguay,

AND THE NEIGHBOURING DISTRICTS. 187

only 15 belonged to families completely strangers to Europe. These statements are
doubtless accurate, as far as they go; but the vegetation of those eountries is in reality
more different from the European than such comparisons would seem to imply. For, in
the first place, many of the families and genera of plants which especially predominate in
the Argentine region, and are strikingly characteristic of it, are such as are but scantily
represented in Europe, or make no conspicuous figure here. Such are, in particular, the
families of Solanee, Verbenace@, Amaranthacee, and, perhaps I may add, Malvacee.
Such is the genus Solanum, of which many more species grow wild within a short walk
of the eity of Buenos Ayres, than in the whole of Europe; such is the genus Verbena,
so insignificant in our continent, but playing so conspicuous a part in the Argentine
vegetation, by the number of species, the profusion in which they grow, and the beauty
and brilliancy of many of them. I may add also the genus Eryngium, or at least that
curious section of it which is characterized by narrow and parallel-veined leaves,

Secondly, although the genera altogether wanting in Europe may not form, numeri-
cally, a very large proportion of the Argentine flora, yet several of them are very con-
spicuous, and play an important part in that flora by the number of species or of indivi-
duals. Such are Pontederia, Gomphrena, Teleianthera, Jussiea, Nicotiana, Petunia, Nie-
rembergia, and others. |

Thirdly, on the other hand, several of the families of plants which most abound in
Europe, are nearly wanting, or but very feebly represented, (if we exclude naturalized
plants,) on the shores of the Plata; such are Crucifere, Caryophyllee, Umbellifere
(excepting Eryngium), Boraginee, Dipsacee, and two of the primary divisions of Compo-
site, namely the Cichoracee and Cynaree. "od A |

In the collections in my possession from Buenos Ayres and the Banda Oriental, I find

fourteen families and 102 genera which are not European. The families are:

Commelynacee, Marantacee, Passifloree, |^ Buttneriacee, Tropeolee,

Such estimates are of course liable to some variation, according to the different opinions
entertained by different botanists as to the limits of genera. In the above list I have

taken Endlicher's ‘Genera Plantarum’ for my guide. |
The above observations will show how materially the Argentine Flora differs, in reality,
from that of Europe. What principally contributes to give it, at first sight, a European
aspect, is the great number and extraordinary prevalence of naturalized European plants,
—plants evidently introduced in the first instance by accident, and which, being of a hardy
constitution, and possessing efficient means of propagation, have spread so rapidly as to
cover the soil to a great extent, and actually to predominate over the native growth. No
small proportion of the plants which a stranger will observe in his first rambles in the
neighbourhood of Buenos Ayres are colonists from our quarter of the globe. The fallow
fields about that city are blue with Echium violaceum; the banks of earth are covered
with the common Fennel; the ditch-sides and waste ground are overrun with Chenopo-
dium album, Sonchus oleraceus, and Xanthium spinosum; Trifolium repens and Medicago
denticulata form much of the herbage near the river-side; and among the most common
grasses are Lolium perenne and multiflorum, Hordeum murinum and H. pratense. What
is more remarkable, these intrusive strangers are not confined to the cultivated lands or
to ihe neighbourhood of the city, but have spread far and wide over the open plains. The
“thistles” and “clover” which clothe the Pampas of Buenos Ayres for leagues and leagues
together, have been described by many travellers; they are Carduus Marianus, Cynara
Cardunculus, and Medicago denticulata, all of them European species. The two former
ak spread themselves also over the country north of the Plata, where M. de St. Hilaire
Mies os ee wide tracts of country. It would seem that these temperate regions
rica are peculiarly favourable to the growth of European plants, and that

none of the native ones possess so hardy a constitution, or such powers of propagation, as
these strangers. It is, as Mr. Darwin remarks, a parallel case to that of the horse and
ox, which have, within the last three centuries, spread themselves in such countless num-
bers over the same countries.

It appears to me that this wide diffusion of naturalized plants, originally foreign to the
country in which they now grow, bears in some degree upon the question of specific cen-
tres; or at least is adverse to the views of those who consider the natural distribution of
species as determined solely by favourable local circumstances. These introduced plants
have established themselves so readily and so completely, that it is quite evident, the soil,
climate, and other circumstances affecting their distribution, must be highly favourable ;
yet they did not exist in those countries until introduced by the indirect agency of man.
Therefore it would seem that they were not created indiscriminately in all the situations
naturally adapted to their constitutions. But the general question of the distribution of
plants is too wide for me to enter further upon it in this place.

The social character which is so eminently conspicuous in many of the naturalized plants
above noticed is not confined to them, but is observable also, though in a less degree, in
several of the indigenous plants of the Pampas of Buenos Ayres. The most remarkable
in this respect, as far as I observed, are Verbena erinoides and chamedrifolia, Mitracar-
pum Sellovianum, and a dwarf Solanum ; besides a few grasses, which, as they were not in
flower at the time of my visit to Buenos Ayres, I could not determine. This social growth
of some particular plants, and consequent uniformity of vegetation, has, I think, been
noticed by various naturalists as characteristic of extensive plains. !

Tropical forms of vegetation are not wanting in the Argentine region, but occur chiefly
on the banks and islands of the principal rivers, much more rarely in the open country.
They are principally woody climbers, such as Passiflora cerulea, Stigmaphylion littorale,
two or three species of Paullinia, a Cardiospermum, and a Bignonia; or Leguminose of a
tropical character,—species of Mimosa, Inga, Calliandra, and Cassia. Of the Melastoma-
cee, a family so eminently characteristic of tropical South America, and especially of
Brazil, one solitary species (an Arthrostemma) reaches to the north bank of the Plata,
. but does not cross it. Colonia, opposite to Buenos Ayres, seems to be the most southern
locality of that beautiful order. One Macherium, a very tropical form, grows in the
islands of the Uruguay, near its mouth, and is probably the most southern representative
of the Dalbergia tribe of Leguminose. A few Monocotyledonous genera which have their
head-quarters within the tropics appear for the last time, as we go southwards, on the
banks of the Plata; such are Canna (of which there is one species at Buenos Ayres), On-
cidium, and Tillandsia.

Of the range of Palms in the region in question I have no knowledge. It would appear
from Mr. Darwin’s statements, that they occur here and there as far as 35° 8. lat., which
seems to be likewise their southern limit in Chile.

The southern limit of the Argentine vegetation seems to be determined mainly by soil;
the northern, by climate alone. To the south its extension seems to depend upon that of
the Pampean formation; that is to say, where the calcareous mud and marl of the Pam-

pas are succeeded by the arid gravel or shingle of Patagonia, the character of the vegeta-

190 MR. BUNBURY ON THE VEGETATION OF BUENOS AYRES

tion also changes. The Rio Colorado, in S. lat. 40°, was observed by Mr. Darwin to form
a pretty aceurate boundary-line between these two formations; and he notices* the change
in the vegetable covering of the soil accompanying this change in its mineral nature.
The herbaceous vegetation which clothes the surface of the Pampas pretty uniformly is
succeeded by low scraggy thorny shrubs and dry meagre grasses, which, according to the
accounts we possess, are so thinly scattered over the shingly plains of Patagonia, that the
aspect of the whole country is strikingly barren and miserable. That this change of soil
should be attended with so great a change in the vegetation, while that (more striking in
a geological view) which takes place when we cross the Plata seems to have very little
influence on it, is easily accounted for by the different relations of these soils to moisture.
The surface of Patagonia, composed of loose shingle, is singularly dry; so much so, it is
said, that one may travel for many days together without meeting with a drop of water :
consequently, it is fitted for the growth of such plants only as can bear this remark-
able degree of drought; and the character of the Patagonian Flora, as shown by all the
accounts, is just such as we should expect under these circumstances. On the other
hand, the elay and marl of the Pampas, and the soil, formed of decomposing granite, on
the north side of the Plata, are both sufficiently favourable to the retention of moisture,
and consequently to the growth of an abundant herbage.

To the northward, the Argentine region appears to have no very definite boundary, but
to melt, as it were, into that of southern Brazil. About Porto Alegre, in Rio Grande do
Sul, in S. lat. 30°, and consequently little more than four degrees north of Buenos Ayres,
the botany has a thoroughly Brazilian character, notwithstanding the absence of great
forests. There are abundance of large and showy climbers of a tropical aspect,— species of
Bignonia, Echites, Malpighiacee, Sapindacee ; of arborescent Mimosee ; of shrubby Com-
posite, belonging to the same genera, Vernonia, Eupatorium and Baccharis, which abound
so much in tropical Brazil; and a vast profusion of Myrtles. The numerous Ferns of Rio
Grande are almost all common to that district and Rio de Janeiro, and among them are
two arborescent species, which contribute to give a tropical character to the Flora. Nota
few phænogamous species, also, extend from the tropical parts of the South American
continent as far as Porto Alegre; for example,—Inga semialata, Mutisia speciosa, Bac-
charis dracunculifolia, Gaylussacia imbricata, Echites longiflora, Pleroma virgatum, Mi-
crolicia alsinefolia, Eryngium Pristis, Eriocaulon caulescens; besides others which range
still further south, to Monte Video, such as Baccharis trimera, Pterocaulon spicatum,

Achyrocline flaccida, Hydrocleis Humboldtii, and various grasses. ship
On the other hand, the comparatively small number of Melastomacee, and the abun-

Porto Alegre; but the fact mentioned by M. de St. Hilaire *, that the cultivation of man-
dioca and sugar extends so far south, and no further, seems to point it out as the southern-
most limit of the seasons of tropical Brazil. Mr. Darwin has remarked the rapid change
of climate in proceeding northward from Buenos Ayres, and in accordance with this, appa-
rently, is the change of vegetation.

It would be interesting to compare the Flora of Chile with that of the Argentine region,
but for this I have not sufficient materials. Meyen; in his * Geography of Plants,’ says
that Chile and the countries on the eastern side of the Andes, in corresponding latitudes,
cannot be considered as separate botanical regions; yet the information which he himself
gives, in the same work, as to the Chilian Flora, seems to show that its general physio-
gnomy is very different from that of the Argentine region. The accounts of many tra-
vellers show us that the climate and soil of Chile, in the latitudes of which I treat, are
much more dry than those of the countries near the Plata, and this cannot fail to be
attended with a considerable difference in the vegetation. The Chilian Flora, by Meyen’s
account, appears to be as strikingly characterized by dry shrubs with coriaceous and
glossy leaves, as that of the Plata is by the prevalence of herbaceous forms. In the
abundance of Myrtles, indeed, and of shrubby and arborescent Composite, the vegetation
of Chile may be compared rather with that of southern Brazil At the same time, the
valuable catalogues drawn up by Sir W. Hooker and Dr. Walker-Arnott + show that many
remarkable genera, and not a few species, are common to both sides of South America.

The Argentine Flora has little or no general analogy to that of the southern parts of
North America lying in corresponding latitudes on the other side of the equator; yet
there are some striking, though insulated, points of resemblance. There is a species of
. Cephalanthus on the shores of the Plata; there is an ZEschynomene (Æ. ciliata, Vog.),
excessively like the North American Æ. hispida; a Pontederia, extremely near to cordata,
if not a mere variety of it; a Sisyrinchium, much resembling S. Bermudianum.

If we compare the Flora of the shores of the Plata with that of the Cape of Good Hope
lying within the same parallels of latitude and having nearly the same mean temperature,
we find an extraordinary difference between them. The many points of analogy, and the
general physiognomical resemblance, between the vegetation of the Cape and of New
South Wales have repeatedly been noticed; but between the botany of the Cape and that
of La Plata we find scarcely anything but contrasts. It is not er to discover any points
of resemblance. The general physiognomy of the vegetation is different: the plants of
the Argentine region are chiefly herbaceous, while at the Cape there is a great predomi-
nance of dry, hard, small-leaved shrubs... Almost all the characteristic families and genera
of the two Floras are different: the Solanee, Verbenee, Amaranthacee, Calyceraceæ, He-
lianthoid Composite, Pontederias, Jussieas, Eryngiums, and other forms which make up
the most important part of the vegetation on the shores of shock Tatas are wanting or
insignificant at the Cape, which, as is well known, is characterized by Proteas, Heaths,
Diosning;Pelat goniume, Mesembryanthemums, Aloes, Crassulaceæ, and fiss&acer ; all of
them absent, or nearly so, from the region of which I here treat. Leguminose are abun-
dant in both countries, but for the most part of different genera. Almost the only points

* Journal, 2nd edit. p. 128. + See the Botanical Miscellany, vol. iii.

192 MR. BUNBURY ON THE VEGETATION OF BUENOS AYRES

in the Argentine Flora which strongly remind us of South Africa, are several species of
Oxalis, and some gay-flowered Zridec and Amaryllideæ (Cypella Herberti, Sisyrinchium
Bonariense, species of Habranthus and Zephyranthes), which decorate the banks of the
Plata. The Cactee of the latter country are represented at the Cape by succulent
Euphorbias ; and the herbaceous and half-shrubby Malvaceæ, which are numerous at
Buenos Ayres, have South African representatives in the Hermannie. .

Another thing which strikes us when we compare the Flora of Buenos Ayres with that
of the Cape of Good Hope is, that the former is much less peculiar in its character than
the latter. The Argentine region, considered botanically, is recognized at once as a pro-
vince of South America; all its characteristics are such as belong especially to that part
of the world, while the botany of the Cape has little resemblance to that of the rest of
Africa. The distinction will be very apparent, if we compare, on the one hand, the Flora
of the Plata with that of tropical Brazil, and on the other, the Cape Flora with that of
tropical Africa. ‘The number of peculiar or endemic genera of plants in the Argentine
region is comparatively very inconsiderable; at the Cape, remarkably large. The pecu-
liar genera of the former region almost always consist of a single species, or of very few;
several of the peculiar Cape genera are very rich in species. The number of species com-
mon to the shores of the Plata and the tropical parts of the same continent is considerable,
while extremely few are common to the Cape and tropical Africa.

A part of these differences may be accounted for by the local circumstances of the two
countries. The Cape of Good Hope, as a botanical region, is almost cut off from the rest
of Africa by the great deserts which, to the north of the Orange River, stretch across so
great a part of the continent. Even in the colony itself, the desert called the Great Kar-
roo is known to set an absolute limit to the northward extension of several characteristic
families *, Now there is no barrier of this sort on the eastern side of South America,
where (excepting perhaps the case of Patagonia) the limits of the range of plants seem to
be fixed by climate alone. Moreover, it is probable that the characteristic Cape plants,
generally speaking, are of a more delicate constitution, and have less power of bearing .
change of circumstances, than those of Buenos Ayres; as may be inferred from the much
greater difficulty of cultivating them in gardens.

Another difference that I may notice, between the Cape of Good Hope and Buenos
Ayres, is that naturalized European plants do not play by any means so conspicuous a part
in the botany of the former country as in that of the latter. A good number of introduced

species have indeed established themselves in the neighbourhood of Cape Town, but they
have not spread far,

nor do they appear in any remarkable quantity, nor at all vie with
(much less supersede) the original natives of the soil. It is not owing to the greater
extension of European culture that these plants have been more widely diffused in the
region of the Plata; for although a great part of that country might probably be found
very fit for cultivation, the proportion of it which has actually been brought into that
EA ha wen indeed. The climate, from its greater moisture, may be more favour-
emi "E ~ > that of the Cape, but the chief cause of the difference is probably

* See Burchell’s Travels.

AND THE NEIGHBOURING DISTRICTS. 193

Mr. Brown has indicated a few points of resemblance between the botany of Australia
and that of the temperate parts of South America; but these all, I think, belong to
Chile. On the eastern side of the continent, within the latitudes in question, I am not
aware of any plant that can at all remind us of the Australian Flora. It is rather
remarkable, that the Protea family, which occurs, though sparingly scattered, in Fuegia,
Chile, Peru, Guiana, and tropical Brazil, seems to be entirely absent from the region of
which I treat.

I shall conclude with a few remarks upon some of the families contained in the collec-
tions before me, and on the range of particular species.

Filices.—At Porto Alegre and one or two other points in the extreme south of Brazil,
about 30° 8. lat., Mr. Fox collected fifty-four species of Ferns. This collection strongly
exemplifies the wide range of species in this family, pointed out by Sir W. Hooker and
by Dr. Joseph Hooker ; for nearly the whole are natives of tropical Brazil, and at least
one-half of the number occur likewise to the north of the Equator,—in the West Indies,
Caraccas, Guiana, or Mexico. Two extend even to Europe,—Aspleniwm marinum and
Osmunda regalis. The Rio Grande specimens of this Osmunda agree perfectly with the
ordinary British form.

Of the fifty-four Ferns, forty-nine belong to Polypodiacee* ; two to Gleicheniaceæ, two
to Schizeacee, and one to Osmundacee. Two are arborescent, Didymochlena sinuosa and
Alsophila armata. This, I suppose, is the southernmost limit of Tree Ferns on the eastern
side of South America. |

Buenos Ayres is remarkably poor in this family of plants. During the month that I
spent there, although I paid much attention to botany, I did not observe a single Fern ;
and in the collections made by Mr. Fox, who, I know, took particular interest in this
family, I find only onet Fern from the south side of the Plata. This circumstance is not
at all surprising, for the bare, level, shadeless, treeless plains of Buenos Ayres are pecu-
liarly unsuited to the Ferns. And we may observe, that even where there is a warm
climate and a tolerably large supply of atmospheric moisture, (for both these conditions
exist at Buenos Ayres,) these plants do not seem to flourish unless there be shade and
variety of surface. In accordance with this, is the absence of Ferns from the bare table-
land of Mexicot, and their great scarcity on the open campos of the interior of Brazil.
The neighbourhood of Graham’s Town, in South Africa, has a much drier climate
Buenos Ayres, yet the ravines and rocks there, affording shade and shelter from the wind,

rodu Ferns.
: Eh the Grasses colleeted on the banks of the Uruguay and La Plata, I
find the Poacee (according to the division established by Mr. Brown) to be rather mem
numerous than the Panicee; the former, however, including a few naturalized species.
The comparatively small number of Grasses in the collection does not ape ne je sup-
pose that it is, in this respect, at all a fair representative of the vegetation —

tine region, the local conditions of which appear favourable to this family. I will there-
fore not attempt to estimate the proportional number of Grasses to other orders. I will
merely observe, that, besides some European grasses evidently naturalized in that region*,
there are some apparently indigenous species which have a very wide range. Such are
Cynodon dactylon, which seems to be a native of all the warmer parts of the world, in
both hemispheres; Setaria glauca, equally cosmopolite; Setaria italica, of which I have
specimens from Louisiana as well as from the Uruguay, and which is stated to be a native
of Europe, India and New Holland; Eleusine indica, which appears, from the localities
given by Kunth, to have a vast range in the tropical and subtropical zones; Polypogon
monspeliensis, which I have myself seen at the Cape of Good Hope and at Buenos Ayres,
as well as in the south of Europe; Stenotaphrum glabrum, common to the Cape, Lou-
isiana, tropical Brazil, and the northern shore of the Plata. The beautiful grass Hustachys
petrea may be added, if the Cape plant be really the same with the South American,
which does not seem quite certain.

Eriocauloneæ.—Of this family, so very numerous in tropical South America, and espe-
eially in the interior mountainous distriets of Brazil, I find only one species in Mr. Fox’s
collections from the extreme southern part of that country. This is Eriocaulon (Pepa-
^ lanthus) caulescens, of which there are specimens from Porto Alegre, S. lat. 30°; I met
with it in Minas Geraes, not far from S. Joao d’El Rey; and I have seen a specimen from
Guiana in Sir J. E. Smith’s herbarium.

Alismacee.—A fine species of Sagittaria is plentiful in the marshy pools near the river-
side at Buenos Ayres; it is, I suppose, S. Montevidensis of Chamissot, though it differs
from his specific character in having the back of the leaf quite smooth. It certainly comes
very near to S. sagittifolia, though much larger both in the leaves and flowers. The
downy filaments of the stamens, and yellow anthers, seem, as far as I can judge, to furnish
the most certain characters ; for the leaves of our English Arrow-head are so very variable,
that it is hardly safe to rely upon the distinctions afforded by their more suddenly and
sharply acuminated lobes in the Buenos-Ayrean plant.

Composite.—The celebrated botanist, Schouw, has characterized the countries near the
Plata as the “ Kingdom of Arborescent Composite ;” a title scarcely applicable, for these
plants, like most others of the region in question, have for the most part a herbaceous
character.

Here, as in South America generally, the Composite appear to be the most numerous
family of plants; but I am not able to state their proportional numbers with precision.
Almost all those of the Argentine region belong to the Oorymbifere of Jussieu ; the Cicho-
race? and Cynareæ hardly occur at all, except in a naturalized state. The Labiatiflore,
so characteristic of the western side of South America and of the Andes, are few and
inconspicuous in this region. It is curious, that the genus Mutisia, which ranges all up
the west side of the continent from southern Chile into New Granada, and is scattered
also through Brazil, as far south as Porto Alegre, does not seem to extend to the Plata.
I must own, however, that negative conclusions in such cases are a little uncertain, unless
they rest upon the concurrent testimony of many observers.

* See before, p. 188. T Kunth, Enumeratio Plantarum, vol. iii. P. 157.

AND THE NEIGHBOURING DISTRICTS. 195

The shores of the Rio de la Plata are characterized by many herbaceous Heliantheg :—
species of Leighia, Verbesina, Bidens, &c. The genera Vernonia, Baccharis and Bupato-
rium, so characteristic of tropical Brazil, extend into this region, but no longer in such
amazing numbers. At the Cape of Good Hope, where the abundance of Composite is
. remarkable, the prevailing groups are for the most part different from those of Buenos
Ayres ; in particular, the Everlastings (Helichryseæ), so prodigiously numerous at the Cape,
are comparatively scarce in the corresponding latitudes of South America. The universal
genus Senecio, however, abounds in both countries.

It has been observed, that the species of this family have not in general so wide a geo-
graphical range as might have been expected, considering the facilities for dissemination
afforded by their feathered seeds. Nevertheless, several of the Composite of the Plata are
tropical species, and some even common to both hemispheres. Bidens helianthoides, a
common marsh plant at Buenos Ayres, appears to be a native of Mexico, Guiana, and
Chile. Flaveria Contrayerba is common to Buenos Ayres (Mr. Fox), Peru, and Mexico.
Achyrocline flaccida, common at Rio de Janeiro, was observed by Mr. Fox to range all
the way from that place to the north bank of the Plata, and was also found by Schom-
burgk in Guiana. Gnaphalium Gaudichaudianum, another native of Rio, is in Mr. Fox's
collection from Monte Video. Pterocaulon spicatum appears to have much the same range
as Achyrocline flaccida: I have specimens from British Guiana, Rio de J aneiro, Rio Grande,
and Maldonado*. The first and last of these stations are separated by about thirty-seven
degrees of latitude. Baccharis trimera, DeC., also appears to be widely diffused in South
America: it is one of the most common plants all the way from the gold district of Brazil
to the Serra da Estrella near Rio +; it has been found at Bahia and at St. Catherine's;
Mr. Fox met with it at Monte Video as well as in Rio Grande; and it is probably the
same species that is mentioned by Sir W. Hooker f as found by Dr. Gillies in the Pampas
of Buenos Ayres, and by Tweedie in Northern Patagonia. All these, however, are in-
stances of diffusion in latitude: I have not found among the Composite of the Argentine
region (excluding evidently naturalized plants) any that are common to more than one
continent.

Asclepiadeæ.—This order is numerous in Rio Grande and the Argentine region, as it
seems to be in South America generally, although these countries by no means rival the
Cape of Good Hope in the abundance of Asclepiads. One species, the Gomphocarpus fru-
ticosus, widely diffused over the warmer parts of the old world, occurs also, I believe, at
Monte Video; at least the specimens gathered there appear to me undistinguishable from
the Cape plant; but it may have been accidentally introduced to this locality. With the
exception of this genus and Cynanchum, the Asclepiads of Rio Grande and the Plata all
belong to strictly American forms, among which Oxypetalum predominates in number. I
find in Mr. Fox’s collection only one species of Asclepias (A. citrifolia?); the A. Curas-

savica, so common on the coasts of tropical Brazil, does not, apparently, extend much
beyond the tropic. | :
Umbellifere.—These plants, observed by Humboldt to be very rare within the tropics,
unless at great heights, seem to be pretty numerous in the subtropical zone of the south-
ern hemisphere, but mostly of rather peculiar forms. The Umbellifere of La Plata and
Rio Grande belong chiefly to the genus Eryngium, and especially to that curious section .
of it with long, narrow, linear or sword-shaped, parallel-veined leaves (or phyllodia), which
are often fringed with bristles, or with bristle-like teeth. In Mr. Fox's collections from
those countries, I find nine species of Eryngium, of which five belong to the parallel-
veined section. One of them (E. aquaticum ?) is a stately plant, 5 or 6 feet high, a con-
spicuous ornament of the marsh ditches near Buenos Ayres, with leaves that remind one
of a Bromelia or Pandanus. Another (seemingly E. Pristis) extends from the tropical
regions of Brazil as far as 30° 8.; it is very frequent on the campos of Minas Geraes
(about 207-21? 8.), at the elevation of 2000 to 3000 feet, while in Rio Grande Mr. Fox
seems to have found it at a comparatively low level. Many Eryngiums of the same
group, and, as it appears, nearly allied to these South Brazilian kinds, were found by
Humboldt and Bonpland on the high lands of Mexico, and there are several in Chile.

I find very few other Umbellifere from the Argentine region in the collections before
me. This part of South America seems to be destitute of those curious Mulinee (Bolax,
&e.) which are so characteristic of Fuegia, the Chilian Andes, and the Falkland Islands.

At the Cape of Good Hope, in corresponding latitudes, we find very different forms of
this, as of most other families. That country has no Eryngiums, and I believe only a
solitary representative of that division of the order, the Alepidea ciliaris. It has, how-
ever, a considerable number of Umbellifere,—not less than 120 species, according to
Harvey,—and among them several peculiar genera, of which Hermas and Arctopus are
the most singular; likewise many remarkable forms of Hydrocotyle, which seem in a
manner to represent the South American Mulinee.

Several European Umbellifere have become naturalized at Buenos Ayres, and among
these the common Fennel is extremely conspicuous, covering the banks of earth between
the cultivated fields in immense profusion, and forming a distinctive feature in the scenery.
I have heard it remarked, by residents in that city, that when the wind called the Pam-
pero, which blows over the inland plains, is coming on, its approach is always announced
by the smell of Fennel, which it brings from the beds of this plant that it passes over.
Mr. Darwin observed the range of the Fennel to be limited on the south by the Rio Sa-
lado, rather less than 100 miles south of Buenos Ayres. -

Malpighiaceæ.—This is one of the characteristic tropical American orders which die out
rapidly in proceeding towards temperate latitudes. Two species only, as far as I know,
are found on the south side of the Plata, namely Stigmaphyllon littorale and Heteropterys
glabra. In Rio Grande, Mr. Fox collected nine Malpighiacee, of which one is a Galphi-
mia, the rest belong to Banisteria, Stigmaphyllon, and Heteropterys.

Tropeolee.— Tropeolum (Chymocarpus) pentaphyllum, abundant in the hedges about
Buenos Ayres, seems to be the only plant of this order on the eastern side of temperate
-South America. Its head-quarters are evidently on the western side of the continent.

AND THE NEIGHBOURING DISTRICTS. 197

Œnothereæ (Endl.).—Of the four principal genera of this family, Jussiea, Œnothera,
Epilobium and Fuchsia, the Argentine region possesses only the first two. Some species
of Jussiæa are plentiful on the marshy shores of the Plata, but as the genus has its head-
quarters within the tropics, so it is richer in species at Porto Alegre than at Buenos
Ayres. From this latter place I possess three species of Œnothera. Fuchsia, so charac-
teristic of the west side of South America, seems, on the eastern side, to be confined to
tropical Brazil.

Melastomace@.—One species only (as I have already mentioned) extends as far south
as the Rio de la Plata, but does not appear on the southern bank of that river. Even in
Rio Grande, the plants of this order are few when compared with their abundance in
tropical Brazil, and when compared also with the allied family of Myrtles. I am aware of
only nine species from the southern extremity of Brazil.

Leguminose.—The Argentine region is not particularly rich in these plants; at least,
they by no means form so important a part of the vegetation as in tropical Brazil, in the
south of Europe, or in Australia. The Legwminose of the region in question belong, with
few exceptions, to genera widely diffused, such as Crotalaria, Lupinus, Tephrosia, Indigo-
fera, Desmodium, ZEschynomene, Lathyrus, Clitoria, Cassia, Mimosa, Inga, Acacia. This
is quite a contrast to what is observable at the Cape of Good Hope, where the number of
peculiar or endemic genera of this order is remarkably great. The observation which I
have already made, as to the small number of peculiar forms in the Argentine Flora, when

. Æompared with that of the Cape, is particularly exemplified in this important family. The
same holds good, perhaps in a still greater degree, if we compare it with the Flora of corre-
sponding latitudes in Australia. It may be observed, also, that the greatest part of the
Leguminose of the Plata belong to genera which are principally tropical, and which only
straggle, as it were, into cooler latitudes; such are all but two, or perhaps three, of the
genera mentioned above, One is almost tempted to say that the vegetation of this region
is a mere modification, a reduced or dwindled form, of the Brazilian, instead of being a
separate and strongly marked Flora like that of the Cape.

Again, at the Cape, the Lotee predominate remarkably over the other papilionaceous
tribes; in the region of the Plata, the Hedysaree and Phaseoleæ are at least equally
numerous. Cesalpinee and Mimosee are more numerous on the banks of the Plata than
in the same latitudes in South Africa. In that country, south of the Orange River, I
know of only two species of Acacia, although these are so abundant (one of them espe-
cially) as to give a distinctive character to the scenery; nor, as far as I am EOS
there any other Mimosee south of the same river, although, to the north of it and at
Natal, (about the latitude of the southern extremity of Brazil,) they become numerous.
Mr. Fox’s collections from Buenos Ayres and Uruguay (between 33° and 35° 8. lat.)
include five species of Mimosa, one of Desmanthus, two of Calliandra, and five of Acacia ;
yet none of these are so abundant as to form characteristic features of the country, like
the Acacia horrida and Caffra in the eastern part of the Cape colony. The Casalpinee
of these latitudes are principally Cassie, of which there are several species at Buenos
Ayres. The magnificent Poinciana Gilliesii is said not to be indigenous there, though
now well established on the banks of the Plata.

198 MR. BUNBURY ON THE VEGETATION OF BUENOS AYRES.

Daubentonia punicea, stated by Cavanilles to be a native of “New Spain,” was observed
by Mr. Fox to grow wild, sparingly, on the bank of the Rio de la Plata, below Buenos
Ayres, and in great abundance and beauty on the banks of the Uruguay, near its mouth.
It is certainly quite possible that the plant may be common to both countries, but it is
also, I think, possible that Cavanilles, who saw it only ina botanic garden, may have been
misinformed as to its native country, and that the Argentine region may have an exclusive

claim to it.

Several European Leguminose are naturalized at Buenos Ayres; they are chiefly Tri-
Jolieæ, in particular Medicago sativa and denticulata, Trifolium repens, Melilotus parvi-
flora.

Indigofera Anil, apparently a general plant thoughout the hotter parts of America, was
observed by Mr. Fox to be common all through South Brazil and the Banda Oriental, but
not to occur south of the Rio de la Plata. _Æschynomene ciliata ranges at least from
Guiana to Buenos Ayres, and, as Mr. Bentham observes, it is scarcely distinguishable from
the North American ZZ. hispida, which is found as far north as Philadelphia. Another
Æschynomene, from Buenos Ayres, seems to agree with the Æ. conferta from British
Guiana.

The tree which I am about to describe (from young ones growing in the Botanic Gar-

precious aromatic, called Aloe-wood, is a native of the mountainous districts to the east

and south-east of Silhet *, the most easterly province of Bengal, in about lat. 24°-25° N.,

.* Extract of a letter from Robert Keith Dick, Esq., the Judge and Magistfafe at Silhet, to Dr. Roxburgh, dated
Silhet, 9th December, 1808 :— ; , .

“] am much obliged by your affording me the perusal of the mpeg ons d account of the dggur Hw and in
returning it, I take the opportunity of giving y ou such information on that subject as I hehe able to pun lately m
short interview with a landholder in this district, who employs his own ryuts in procuring Aggur wood in the hills
adjoining his property, and is himself concerned in the trade of it; and as it was hastily committed to paper, previous
to my reading the enclosure, it may prove so far satisfactory, in as far as some of the particulars nearly correspond.

* The wood is brought here for sale from the country of Kuchar, and from the southern parts of this Zillah, par-
ticularly the divisions of Puthureea and Lunglah. The tree is known in the hills here by the Bengal name, Tuggur.
Its extreme height is from sixty to seventy haths (cubits), and the trunk from two to so and a half haths in dia-
meter. The general height of a full-grown tree is from twenty to thirty PED Ug UN part. the wood
which is reserved for the extraction of the Uttur, the rest is useless,—at least never applied to any purpose in this
district. I have not been able to procure any information about the flower, or seed of the tree; they say neither have

‘been seen here. This.is perhaps owing to the people going to cut the wood chiefly at one period of the year, viz.
the dry season. It is a precarious and tedious business procuring the wood which yields the Uttur, as few trees con-

where, by various accounts, they attain to a very great size,—as much as about 120 feet
in height, with a trunk of above 12 feet in circumference. Accounts from Assam make
it still larger. Flowering-time, in its native soil, uncertain; but in this Garden a very
healthy young tree, out of several that were sent to it some years ago by Mr. Robert Keith
Dick, the Judge and Magistrate at Silhet, was in flower in March and April last, and
again in April 1810.
Dzsc. Trunk (in our young trees) straight, and clothed with thin, smooth, ash-coloured
‘tough bark. Branches nearly erect, with their terminal, bifarious, alternate, extreme twigs
recurvate, bark of the branches light grey, with many small ferruginous fissures; young
shoots clothed with white, soft, appressed hairs.. Wood white, very light, soft and porous.
Specimens from large trees in their native soil are also uncommonly soft and light, with
a slight tinge of yellow, and not unlike the softest porous deal; every part inodorous, and
nearly tasteless. The moisture (for nothing like exudation is found here) scraped from a
fresh-cut twig was rubbed on the eye and eyelids of a chicken, without producing any
inflammation or apparent irritation. This does not accord with what Father Camellus
says of the true Agallochum tree, viz. “The bark is filled with virulent, milky juice, so
very caustic as to cause blindness if it gets into the eye,” &c. I can well believe the pale
milky juice of Excecaria Agallochum very capable of doing injury to tender parts, and
probably our reverend traveller may have lighted upon that tree, which was said to yield
an inferior sort of Agallochum. Leaves alternate, bifarious, short-petioled, lanceolar, firm
and smooth, lucid deep green, except while very young, then somewhat sericeous, which
is more conspicuous underneath, taper acute pointed; entire waved margins; length from
3 to 6 inches, and from 1 to 2 inches broad. Veins nearly as fine as in Calophyllum Tno-
phyllum. Petioles very short ($ or 4 of an inch), rugose, and a little hairy. Stipules none,
except an opposite, oblong, hairy scale or two at the base of the most tender axillary
shoots, like those of a gem, or bud. Inflorescence simple, solitary, subsessile, beautiful,
small, spherical umbels, at nearly equal distances between or from the leaves (internodes).
Flowers numerous (20-40 to the umbel), pedicelled, small, pale greenish yellow, inodo-
rous. Bracts none. Calyx 1-leaved, campanulate, permanent, half 5-cleft ; segments

tain any ; and such as do, have it very partially distributed in the trunk and branches. The people employed in this
business proceed two or three days’ journey among the hills, jungles and mountains, and without discrimination cut
down the trees as they are found, young, old and withered, but the latter are generally preferred; they then, on the
spot, search for the Aggur, which is done by chopping off the bark, and into the wood, until they observe dark-
coloured veins, yielding the perfume which guides them to the place containing the Aggur, and which generally
extends but a short way through the centre of the trunk or branch. In this manner they search through the whole

tree, and bring away only such pieces as contain the oil, or have the smell of it. In this state there are four denomi-
nations, viz.

Ist. Ghurkee (sinks)...... So ee which sells from 12 to 16 rupees per seer (of 2 Ibs.),
2nd. Has no other name than Doim.... ditto 6 to 8 ditto
3rd. Simula (floats) ................ ditto 3to 4 ditto
4th. Choorum (small pieces, which float) ditto lto 14 | ditto

* The tree grows in sandy as well as clayey soils, on plains, and on the sides and tops of the hills; neither root,
epis nor bark yield any Uttur. Some trees will produce a maund (80 lbs.) of the four sorts. The oil is obtained
y bruising the wood in a mortar, and then infusing it in boiling water, when the Uttur collects itself on the surface."

ovate, obtuse, spreading. Corol none. Nectary of 10, oblong, obtuse, hairy scales, which
are inserted into the mouth of the tube of the calyx, alternate with the filaments, slightly
incurved, so as to form a dome over the germ, its mouth being shut up with the stigma.
Filaments 10, shorter than the nectarial scales, coloured reddish at top. Anthers erect,
oval, 2-lobed. Germ superior, ovate, smooth, 2-celled, each cell containing a single oblong
ovule, attached to the partition above its middle. Style short and thick. Stigma large,
glandular, obscurely 2-lobed. Capsule drupaceous, clavate-turbinate ; length rather above
an inch, and the diameter about half the length; of a soft fleshy texture, and villous over
the surface, like a peach; colour olive-green, its contracted base embraced by the perma-
nent calyx; 2-valved, opening round the apex (like the envelope of the nutmeg) ; 2-celled,
partition opposed to the valves: one of the cells is generally abortive. Seed solitary, oval,
with a large, straight, spongy, pointed horn from the base, which is about as long as the
body of the seed. Integuments 4. Exterior, while recent, soft and white, when dry, dark
brown and villous on the outside. It is a continuation of this envelope which forms the
horn of: the seed; on the inside a vertical, brown groove, in which the filiform umbilical
cord is lodged, which connects the apex of the horn to the top of the partition; second,
. while recent, thick, and hardened at the base only, which is pointed and projects a little
into the spongy horn; when dry, dark brown, smooth, hard and brittle; on its inside a
slight groove is also observed, corresponding with that of the exterior integument; third,
soft, brown, and rather spongy; fourth, or innermost, a thin pearl-coloured membrane
adhering to the embryo. [Note. The last two not easily detected in the fresh seed,
but when dry very conspicuous.] Perisperm none. Embryo inverse, when dry very
pale yellow. Cotyledons conform to the seed. Plumula 2-lobed. Radicle subrotund,
superior. ! À ;

The foregoing is a faithful description of the tree which blossomed in this Garden in
March and April 1809 and 1810. And that of the pericarpium and seed is not only taken
from that which the same tree produced, gathered with my own hand, but also from some
seeds which Dr. Buchanan sent from Goolparah, on the banks of the Megna or Brachma-
putra, to Sir John Royds, who obligingly parted with them to enable me to render my
account of this interesting tree more satisfactory; and again in 1810, from Mr. Richard
Matthew Smith, of Silhet, gathered from a tree growing in his own garden at that

lace. |
i At present it is not possible for me to affirm that this is the tree which produces the
real Calambac or Agallochum of the ancients, but there seems more reason to think it
went to the westward from our eastern frontier, than to suppose it was carried from
Cochin China, or any other country in the vicinity of China, where it has always been
held in the highest estimation. Small quantities are sometimes imported into Calcutta
from the eastward ;' but such is always deemed inferior to that of Silhet.

There is a wonderful agreement between the various but imperfect accounts of the
trees said to produce this valuable drug, and that which I have now described and
figure ,
gre: description of the specimen * presented to him by Sonnerat agrees almost

exactly with our plant. The inflorescence is only required to confirm their being the
same species, or different. Of their belonging to the same genus there can be no
doubt *.

Cavanilles describes and gives a figure of the Garo de Malacca of Lamarck, in his
Seventh Dissertation on the Plants of the Class Monadelphia, page 377. t. 224, under
the name Aquilaria ovata, which is continued by Willdenow in his edition of the * Spe- :
cies Plantarum’ of Linnæus, vol. ii. p. 629. His description differs little from that of
Lamarck, and his figures, so far as they go, agree uncommonly well with our subject.

I have not ventured to quote Agallochum secundarium (Rumph. Amb. ii. 34. t. 10),
though much inclined to think they are the same. His description and figure of the
specimens he received under the name Agallochum malaccense, so far as they go, agree as
well with our tree as can be expected, and as well as the generality of the figures in that
work do with the plants they are intended to represent. We must, however, suppose the
fruit inverted in his plate; which is the more excusable, as it was not growing on, or
naturally attached to the branch the figure is taken from, but tied to it.

Keempfer, that most accurate writer, in his * Amoenitates Exotice,’ page 903, gives a
figure and description of the small plant of the Agallochum tree, which with great diffi-
culty he obtained from distant mountains, under the name S?nkoo, both of which agree
exactly with some young plants of nearly the same size (lately sent from Goolparah by
Dr. Buchanan, and from Silhet by Mr. Smith) now growing in this Garden, even to every
one of the plants being uniformly divided into two little branches, which with their leaves
have the precise appearance of Keempfer’s figure. |

About the time that Keempfer made his voyage to Japan, our countryman, Mr. James
Cunningham, was employed by the English East India Company on the coast of China,
where he must have seen the fruit of this tree, which he describes so well, viz. ** turbinate,
villous, size of a yellow Myrobalan, with a thick cortex, opening into two, and containing
' two seeds separated by a partition, with membranaceous appendages (probably what I
call the horn), and resting on a five-parted calyx.” Until Gærtner’s work appeared, this
would have been reckoned a full and accurate description of the seed-vessel of my Aqui-
laria Agallocha. —

Loureiro's Ophispermum sinense, ‘Flora Cochinch.’ p. 944, is no doubt another spe-
cies of the same genus, and if he, or his editor, had omitted the words “flos terminalis,
solitarius," I should have concluded they were the same; and unreasonable as it may —
appear, I must also remark, that I think, whoever reads with attention, and compares with
this, his aecount of the nature and production of Aloe-wood in the * Memorias de Aca-
-demia Real das Sciencias de Lisboa, vol. i. p. 402-415, will find a striking similarity in
, many respects, viz. size and habit of the tree; smoothness and fibrous texture of the bark,
of which paper is made in both countries; shape, texture and appearance of the leaves ; in

* Since writing the above, Dr. Roxburgh has received living plants, and perfect capsules with their seeds, of the
Garo de Malacca, from Captain Farquhar, the Governor of Malacca. They are not to'be distinguished from some
plants - the same size, and seed-vessels of his Aquilaria Agallocha, very lately sent to this Garden by Mr. Smith
from Silhet, a proof next to positive of their being the same: for positive proof we must wait till the Malacca plants
flower, or till specimens in flower, which Captain Farquhar has promised, are procured.

the want of odour and taste in every part thereof, except the drug itself; in no part of the
tree being lactescent or poisonous; in the wood being white, light and porous, &c. &c. I
place little confidence in his description of the parts of fructifieation, as he acknowledges,
in Willdenow's edition of his ‘Flora Cochinchinensis,’ to have only once seen a mutilated
branch of the tree in flower, which by long carriage had the petals, anthers and stigma
much bruised and torn. And if the natives of Cochin China are not more honest than in
most other parts of South Asia, they would not scruple to give him the fruit of any other
tree for that of his Aloexylum. I am therefore not much inclined to give any great degree
of credit to the natural character of a plant wrote under such circumstances, and rather
think the tree which produces the Aloe-wood of Cochin China, and the Aggur from the
vicinity of Silhet, are the same.

The tree which furnishes this precious incense is chiefly found in that part of Asia
called the Peninsula beyond the Ganges. The mountainous countries to the east and
south-east of Silhet, where our tree grows, are fairly within this division, and correspond
pretty well with the range given by Loureiro to his Aloexylum verum or Agallochum,
which is some small additional proof of their being the same; and, indeed, through the
whole of the above notices, taken from such authors as are within my reach, there runs
such an uncommon share of coincidence, as to induce me to believe they all relate to the
same identical object. By this belief I must acknowledge my account of my Amyris
Agallocha, so far as it relates to its yielding Calambac, to be erroneous. It is needless
to detail the source of the error; suffice it to say that I acknowledge it, and also acknow-
ledge myself to have been much to blame for believing those who gave me the informa-
tion, which has unfortunately been published, or publishing, in the third volume of my
‘Indian Plants.’

Remarks by Henry THOMAS COLEBROOKE, Esq., F.R.S., F.L.S. &c.

The information received from Mr. Dick, concerning the manner of collecting the Aloe-
wood, corresponds so nearly with other notices on the same subject, as to afford a strong
confirmation of their general accuracy.

The following account is by the author of the ' Mekhzen úl adveyeh,’ whose near rela-
tion to the Nawab Mahammed Reza Khan afforded him opportunities of inquiry, of which
he diligently availed himself.

“ Und signifies wood or branch, and emphatieally, the wood called Ud Hindi, or, in
the Hindi language, Agar. It is obtained from a species of tree found in the mountainous
country of Jentiya, near Silhet, in the north-east of Bengal*. ’

«The tree is very lofty, its trunk and branches are generally crooked and rather soft,
so that neither clubs and walking staves, nor bowls and platters, can well be made from

them, by reason of their softness and crookedness. Besides, the tree is in many parts
- hollow.

* Until the wood be old and have remained long after being cut down, so that it may
decay and rot, it does not acquire its proper fragrance. To accelerate this change, the
wood is buried in moist ground, and being afterwards dug up, so much of it as is dark-
coloured'and of a glossy unctuous appearance, and found upon trial to sink in water, is
selected and set apart under the denomination of gharkí. Any remaining portions of
unmellowed wood are carefully separated from it by means of an iron instrument to
obtain the gharké in a pure state. Specimens which sink but partially are termed nim-
gharkt, or semi-mergent. Those which float are called semleh, or dregs, and are the most
common but least esteemed. '

“ This fragrant wood is of various sorts, distinguished by the names of Hindi, Sama-
dárit, Kumärt, and Mandali. The Hindi is of the darkest colour; the Samadüri has a
more unctuous appearance than the Indian sort. The Kumart is of a lighter colour. "The
Hindi (should be Mandalt) is the most fragrant of all. |

* [t is likewise distinguished as Bari and Jabalf (rustic and mountaihous), the latter
with black streaks, the former with white; some, however, reverse these characters.

“The Samadurt is named from the country whence it is brought ; so is the Kumärt!.

“In medicine, the Hindi from Silhet in Bengal, of the quality called gharkt, being
bitter, fragrant, unctuous, and a little hard, is preferred$, because the Aloe-wood of other
places does not equal it in fragrancy and excellence. |

* In some recipes and prescriptions, it is directed that crude did should be taken ||.

* The ‘ Tohfet úl muminin ’ says, it is a tree which grows in the islands of China and India.

+ The ‘ Tohfet úl muminin’ writes this Samandért.

.l The varieties of this wood are denominated from the countries which produce them, as Samandirt, Hindi, &c.—
` Tohfet úl muminin. |

$ The best kind is black, hard, shining, fragrant and bitter, sinking in water. This is the Hindi, and the Kumárí

is of a lighter colour. The Samandürt is more unctuous. The rustic and mountainous varieties of it have white stripes.
That which swims in water is bad.—Tohfet úl mumintn.

| This direction is to be found also in the recipes of the Greek and Arabian physicians, compiled by Nicolaus My-
repsicus. See Rumphius, ii. 39.

DR. ROXBURGH ON THE GENUS AQUILARIA. 205

This is intended for a caution against employing that from which the essential oil has
been already extracted, for fraudulent dealers sell the refuse of the wood after the oil has
been drawn from it. The process of extraction consists in macerating in water and then
. distilling. The produce of distillation, on cooling, yields the essential oil. Some put a
few almonds with the residuum and extract the oil by inversion. This is termed Chwwah-
agar. It is not so fragrant as the genuine Chúwah, obtained without the addition of
almonds, from the raspings of Aloe-wood which have not been distilled. Some again mix
raspings of Sandal-wood, and proceed to distil, and then collect the essential oil from the
produce of the distillation when cold. This likewise is less fragrant than the purer kind.
... *'The author of the * Akhtiyárát-bádóí' has said, that it comes from Bandar Chineh,
situated at a distance of ten days from Java; and this is exceedingly scarce, so that it is sold
for its weight in gold. It appears to have no smell, but when it is held in the hand and
becomes warm, it sweats and diffuses a most exquisite fragrance, which is very permanent.
This is true, and agrees with what the author has also learnt from oral information. The
name may be merely an error of the transcriber.

* Another sort of wood, very similar in its appearance to the Ud, is found in Bengal,
and is sold for it to the unwary. It is named Tagar*.” ;

The close of this passage may excite a doubt whether the tree mentioned by Mr. Dick's
informant, under the name of Tagar, be really the same with that from which the Agar,
or Aloe-wood, is obtained. However, it is not unlikely, notwithstanding the general accu-
racy of the author of the * Mekhzen úl adveyeh,’ that his distinction between the Tagar
and the Udd is unfounded.

The four varieties of Ud noticed by this author correspond nearly to the four sorts
which the Arabian writers have described under similar denominations, taken, as observed
by them also, from names of places. In the Latin translation of Serapior, the denomi-
nations are—1. Indum, the best sort, black and ponderous, found in a certain island of
India called Finma. 2. Mondanum, so called from the Indian city Mondel. 3. Seificum,
from Seifi, situated at the distance of three days from the place which gives name to the
next sort. 4. Alewmericum, the kind least yalued. In three out of four instances, the
correspondence of names is conspicuous and exact.

Sanscrit writers have three varieties of the Aloe-wood: Ist, 4gur", the common sort ;
or black aloes, being of a darker colour than the common kind; 3rd, Man-
having the fragrancy of the Mallica, or Jasminum Zambac.

suitable appellation for a ligneous substance, in which a diseriminative sign of its excel-
lence is its specific gravity exceeding that of water. Grammarians have therefore given a
different turn to the etymology of the word, as indicating a substance than which nothing
is weightier, that is, more valuable*. I observe, nevertheless, among the Sanscrit syno-
nyma for Aloe-wood, Laghí, properly signifying light. It is difficult to assign a satisfac-
tory reason for this name.

Other Sanscrit denominations which merit notice are, Crimija, signifying produced by
insects, and Gandha-cashtha, fragrant wood. ' The first implies a notion, which is not an
improbable one, that the conversion of the wood into an aromatic substance is occasioned
by wounds of insects. The other corresponds in its import with the Arabic name Und, a
term answering in sense, as in sound, to the English word wood, and applied emphatically
by the Arabian physicians to the aromatic wood in question.

Avicenna? has treated, under separate heads, of Udd (which his translator writes Haud)
and Aghälujt, written in the Latin version Agalugen. But later authorities among the
Arabian and Persian physicians concur in affirming that Aghaluji is the same with Ud,
being its Greek denominationt. They clearly intend the Agallochon of Dioscorides $.

It is not, therefore, right to derive Agallochum from the Arabie, since this, on the con-
trary, is confessedly borrowed from the Greek. Neither is its origin to be sought in the
Hebrew Ahalim and Ahaloth, as proposed by Salmasius|| since it is more obvious to de-
duce it from the language of the country whence the drug was brought, and the Indian
name guru, or with the Sanscrit pleonastie termination ca, Aguruca, is much nearer to
the sound of the Grecian term. |

It may be remarked by the way, that the Portuguese Pao de Aquila, as noticed by
Rumphius, is an undoubted corruption either of the Arabie 4gAálují or of the Latin
Agallochum, and it is, by a ludicrous mistake, that from this corruption has grown the
name of Lignum Aquile, whence the genus of this plant now receives a botanic appellation,
and which many authors have vai y attempted to distinguish from the Lignum Aloes
and Calambac **.

The generic and specific names of the plant then are both drawn from the same original
term, a circumstance, however, not unprecedented in the Linnean nomenclature.

XXII. On Acradenia, a new Genus of Diosmeæ. By RICHARD KIPPIST, Esq., Libr. L.S.

Read June 1, 1852.

THE plant to which I propose to call the attention of the Society this evening, is one of
a highly interesting collection, formed in the neighbourhood of Macquarie Harbour, by
the indefatigable Secretary of the Royal Society of Van Diemen’s Land, Mr. Joseph Mil-
ligan, by whom, through the instrumentality of our lamented member, Mr. Bicheno, they
were kindly presented to the Society. |

It belongs to the Diosmeous section of Rutacee (Tribe Boronieæ), and in habit most
nearly approaches Zieria, to the larger-leaved species of which it bears, at first sight, con- .
siderable resemblance. From this genus, however, as well as from Melicope, Boronia,
and Cyanothamnus, it is readily distinguished by the quinary division of the parts of the
flower, and by its more numerous stamens. From Eriostemon, Crowea, and Philotheca,
with which it agrees in the number of its floral organs, it differs in having perfectly
glabrous filaments, and smooth inappendiculate anthers; and from the latter genus,
in addition, by the filaments being distinct, not, as in Philotheca, united below into
a tube. !

Another genus of Australian Diosmeæ with which it accords very nearly in many of its
artificial characters, is Geleznovia, a remarkable plant with the general aspect of Erio-
stemon, recently described by Turezaninow, from Drummond's Swan River Collections, in
the Bulletin of the Imperial Society of Naturalists at Moscow. The points of agreement
are, the quinary division of the calyx and corolla, the smooth subulate stamens (ten in
number), and glabrous inappendiculate anthers; but the calyx in Geleznovia is coloured,
and as long, or rather longer, than the corolla, the anthers are strietly terminal, and the
entire surface of the carpels is covered with elevated tubercles, each surmounted by a tuft
of radiating hairs. imos

From all the above-mentioned genera the Tasmanian plant is distinguished by the
structure of its ovaries, which adhere closely together, and are everywhere clothed with a
dense tomentose covering; except that each bears, at its upper external angle, a naked
sessile tubercle or gland, large enough to be readily observed with the naked ey e; a cha-
racter which I have been unable to discover in any closely allied genus, and a has con-
sequently suggested the name Acradenia, by which I would propose to designate my

lant. :
R I am unable to speak positively as to the precise nature of these glandular ges or
to say whether any exudation proceeds from them : when — under t " ee
scope, they appear to be perforated by a tube, widening below, and nn ing “ss
the internal cavity of the carpel. From the exact correspondence in their position, how-

ever, they are probably analogous to the cornute appendages which crown the ovaries of

208 MR. KIPPIST ON ACRADENIA,

some species of Phebalium, but in that genus they are occasionally developed into subu-
late or nearly cylindrical horns, almost as long as the carpels themselves.

In the structure of its mature capsule, Acradenia appears to differ from most, if not
the whole, of its more immediate allies, the endocarp remaining, when ripe, firmly united
to the epicarp, instead of separating from it in two elastic valves, as is usually the case in
other Diosmee.

We have, unfortunately, no information from its discoverer with respect to the dimen-
sions which the plant attains, but the dried specimens have all the appearance of having
been broken off from a shrub of considerable size. They are much branched, and copiously
furnished with opposite ternate leaves; these are remarkable for their coriaceous texture,
and the extreme roughness and harshness of their upper surface, which is dark green, and
covered with prominent glandular tubercles, while the under side is perfectly even, and
(in the dried specimens) of a ferruginous brown.

From its close resemblance in habit to Zieria, I had originally intended to employ the
_ specific name “ zierioides”; but Mr. Brown having kindly communicated to me a speci-

men, gathered by Mr. Milligan on the banks of the Franklin River in April 1842, on a
ticket attached to which Mr. Milligan proposes to name the plant “ Zieria Franklinie,”
after Lady Franklin (who, with her husband, Sir John, were, I believe, his companions on
that journey), I have much pleasure in altering the specific name to Franklinie, in accord-
ance with the wishes of its discoverer. On the same ticket Mr. Milligan speaks of the
plant as handsome and fragrant; but as he at that time saw no flowers, the latter term
can only be intended to apply to the leaves, which, as in the majority of the Diosmee, are
copiously furnished with pellucid dots, reservoirs of essential oil, and exhaling probably
the peculiar odour which characterizes that family.

however, that the plant is not likely at present to ripen its fruit at Kew. Mr. Smith
informs me it was first introduced to the Botanie Garden in 1845, in a case sent by
Dr. M*William from Norfolk Island, where, however, it is scarcely possible that it

XXIII. On the Genus Myrmica, and other indigenous Ants,
By Joun Curtis, Esq., F.L.S. &e.

` Read March 21, 1854.

NOTWITHSTAN DING the valuable volume published by Latreille in 1802 * upon the
Ants, the species inhabiting our island were but imperfectly known until very recently.
That talented naturalist divided the Formicide into several families or sections, which
he subsequently named; and he found simple and admirable characters for dividing the
European forms into two groups.

It is one of the characteristics of the Hymenoptera, that the abdomen is attached to
the trunk by a neck or petiole, more or less attenuated +. Every one is familiar with the
structure of the Wasp, which is a good example of the petiolated Hymenoptera. In the
Ants, however, this connecting portion or petiole is very peculiar in its form, being fur-
nished on the upper surface with scales or nodules f. This forms the basis of Latreille's
subdivision of the Ants, one section having a single scale, the other two nodules on the
ird ERLERNTE RR md edis

It is true that the valuable monographs of Nylander $ and Foerster || have lately cleared
the way and placed us in a better position, but owing to the fact that each species of Ant
exhibits three phases, the study of the family becomes complicated, and unless one can
detect and examine a nest, when the Ants begin to swarm, it is not easy to decide with
certainty upon the relationship of individuals; consequently there are many species
. whose history is not complete, and many points remain unsettled. The workers, or
neuters as they are called, of most species are abundant enough, and the females of some
families resemble them, but the males are generally very different, whilst the females are
often deprived of their wings; and even amongst the workers there are two kinds varying
in size if not in other respects; so that to an unpractised eye a nest might appear to be
inhabited by five different kinds of Ant. $ ;

With such a complication of materials it is not surprising that errors in our nomen-
elature should exist, and I present this Essay to the Linnean Society more with the hope
of inducing young and zealous entomologists to study this interesting family, than with
any great expectation of producing much myself that is new, or of rendering the nomen-
lature perfect.

PR
+ oe Re in € short that the connecting portion is invisible, and the Saw-flics (Tenthredinidæ)
are altogether an exception, the abdomen being sessile ; but it is remarkable that the larvee in that j family resemble
caterpillars, and have not only feet, but a greater number than any other larvæ of insects, amounting in some species
to twenty-two, whilst in Lepidoptera the maximum is sixteen feet.

212 MR. CURTIS ON THE GENUS MYRMICA,

On comparing the species of Myrmica in my cabinet with the Collection in the British
Museum, which has been arranged by Mr. Smith, who has paid particular attention to
the Ants, I was enabled to make some notes, and I hope clear up some doubts by the
investigation, having had thereby the advantage of examining the typical specimens pre-
sented by M. Nylander to our national museum.

I therefore propose to describe and figure some English Myrmice, which are either
new, or so little known, that it appears to me impossible to identify the species. I trust
that the figures will at all events render a few species no longer doubtful; and as no dis-
sections, that I am aware of, have been given of Myrmica, nor any very elaborate charac-
ters exhibited, I shall endeavour to supply the deficiencies.

Male. Head smaller than the thorax, rhomboidal (fig. 11): eyes globose and prominent: ocelli very
distinct, in triangle behind the eyes. Antennz inserted in cavities in front of the face, approxima-
ting, not long, geniculated, slightly clavate, hairy and 13-jointed; basal joint generally one-third of
the entire length +, second obconic, the six following more or less ovate, the remainder forming
a slightly enlarged club of obovate joints, the last being the longest, stoutest and conical (fig. 1).
The trophi are small: Mandibles meeting in front, hairy, narrowed towards the base, dilated ante-
riorly and truncated obliquely, the margin forming but few teeth (2). Maxillæ producing longish
drooping Palpi, pilose and 6-jointed, three basal joints the stoutest, fifth the shortest, sixth the long-
est, elliptic-conic (3). Mentum obtrigonate, with a small semicircular labium: Palpi remote, not
long, but slender and 4-jointed, second joint the longest (4). Thorax attached to the head by a
distinct neck, elongate-ovate, scutel semicircular, postscutel produced into a short spine at each angle.
Petiole stoutish, composed of two knots, the basal one somewhat pear-shaped, second broader and
globose: abdomen larger than the thorax, ovate-conic, the basal segment covering more than half
the surface. Wings ample, especially the superior, which exhibit a longish stigma with two dis-
coidal cells, the upper one large and partially divided by a short nervure ; the posterior cells incom-
plete (fig. 13). Legs not long but slender; anterior tibiz furnished with a longish spine at the apex,
slenderer in the others: tarsi 5-jointed, basal joint of first pair very rigid and arched at the base,

Female stouter. Head much larger: eyes small: ocelli very minute. Antenne less elongated than in
the male, and 12-jointed; basal joint always elongated, second longer than the six following, and
the club more robust (5). Mandibles large and prominent, concavo-convex, forming serrated
spoons, the teeth more numerous than in the males (6). Palpi similar to those of the neuter.
Thorax rather short, broad in front and obtuse, postscutel producing two longish slender spines.
Petiole and abdomen similar to the male, but furnished with a concealed sting. Wings as in
the male. Legs stouter, the thighs and tibiæ being incrassated; tarsi similar, but shorter and
stouter.

Neuter resembles the female, but is much smaller; the Antenne are longer in proportion, and 12-
jointed (7). Ocelli none. The trophi are very minute, excepting the Mandibles, which are com-
paratively large, crossing, very dilated at the extremity, truncated obliquely and producing 5 or 6
teeth (8). Labrum undiscovered. Maxille terminated by an oblique subovate very hairy lobe,
and furnished with a slender drooping Palpus of 6 joints (9). Mentum chalice-shaped or obconic,
with two remote Palpi of 4 joints (10). Thorax much narrower than the head, contracted at the
middle; postscutel with 2 slender spines. Wings none. Sting concealed.

brinodis, Nyl. var.

This is a most abundant insect, forming colonies, in meadows, on heaths and banks.
The different species of Myrmice live principally under stones and clods, but they secrete
themselves beneath the bark of trees and in moss. It should be observed that the pup
are not enclosed in cocoons, in which they differ from the true Formice. The males fly in
the evening, and the females are frequently found deprived of their wings, after pairing.

As this is undoubtedly the Fabrician species, I have restored the original name. It has
been taken in the middle of July, at Sandown, in the Isle of Wight, by Mr. F. Smith.

4. M. LONGISCAPUS, Curt.

This species resembles M. levinodis, but the males are much smaller, the antenne are
much longer, and instead of the scape being only as long as the two basal joints of the
flagellum, as in M. levinodis and M. rubra (fig. 1), it is equal in length to the eight om
lowing joints (fig.12). The head is less convex, there is no channel down the forehead,

and the clypeus is testaceous (fig. 11). There is a fovea on the hinder margin of the

214 MR. CURTIS ON THE GENUS MYRMICA,

as the species under consideration was taken in abundance, from the same nest in
Scotland in 1825, all having long scapes, it seems to me to be distinct from M. ru-
bra or the allied species: moreover, if this extraordinary disparity of the scape were
merely a variation, how is it that the same difference is not observable in the other
species ?
I possess four males, two females and four neuters, found in July in Perthshire, and I
have received males and females taken out of one nest in the neighbourhood of Man-

chester by Mr. R. Wood.

5. M. PERELEGANS, Curt.

The male (fig. 15) is pitchy, shining: head finely striated, with a faint channel down
the face: mandibles ochreous: antennæ longish, slender and ochreous; scape scarcely
one-third the entire length, pitchy, except at the extremities: fore part of thorax
smooth, with a few comma-shaped impressions and two longitudinal channels in front,
hinder portion striated; scutel roughish punctate-striate ; postscutel regularly and
distinctly striated, abrupt and concave behind, the angles not produced. Petiole stout-
ish, first nodule punctured, second very smooth and shining, as well as the abdomen,
which is tawny, and a little pubescent towards the extremity. Stigma and nervures
nearly colourless. Legs ochreous; thighs and tibiæ pitchy, excepting at the extremities :
length 22 lines, |

Female (fig.16) clear ochreous-red: upper side of head, excepting the margin, black,
more rugose-striate than in the male; the clypeus striated, with a band of very fine striæ
between the antennze, which are fulvous; mandibles bright ochreous, the teeth pitchy.
Thorax similarly sculptured to the male, but the scutel is striated, and the angles of the
postscutel form two long, slender, incurved spines: first nodule with a circular cavity on
the back, leaving an elevation in the centre; second pilose: abdomen entirely glossy
black, with scattered pale hairs. Legs fulvous, the middle of hinder thighs and tibiæ
brown. Stigma and nervures visible, pale fulvous: length 3 lines.

The neuter (fig. 17) resembles the female in form, and is exactly similar in the dispo-
sition of the colours, only that the thorax and petiole are of a deeper brick-red, with the
legs reddish, and all the thighs and legs are darker. The thorax is contracted in the
middle and striate-punctate, forming ridges in front: the pit on the first nodule forms a
circular margin with an island in the centre: length 23 lines. |

This species seems to approach the Formica. subterranea of Latreille, but the neuter
has the upper surface of the head black, and the first nodule has not a long petiole, as
described and represented in all Latreille’s figures. The male has not very pale yellow
legs; nor the female a brown, very shining thorax, with a brown petiole. It may be
related to Fabricius's F. acervorum, but he describes that species as having the back of the
thorax black. |

This new and elegant species I found in J uly 1850, under a stone, on a heath near
Bournemouth in Hampshire, The males were scarce, the females more abundant; the
workers were in considerable numbers, and on being disturbed they ran away with the
pupæ, hiding themselves in holes and amongst the grass. |

I have never met with this species, but Mr. Smith has taken the male, flying in abun-

dance in a fir-grove in Hants, in September, and also under bark of trees in the same
county.

7. M. DENTICORNIS, Curt.

Male (fig. 18) pale dull castaneous, sparingly hairy: head with indistinct irregular
strie; eyes black; mandibles pale straw colour. Antenne fulvous. Thorax smooth,
shining, indistinctly sculptured; the scutel with an ochreous margin, finely striated, as
well as the postscutel, which is concave behind, the angles forming short acute spreading
spines. Petiole with ochreous articulations; basal nodule a little elongated and irregu-
larly striated, second nodule smooth and shining: abdomen very glossy, often darker, the
margins of the segments paler. Wings slightly tinted, the stigma and nervures pale ful-
vous. Legs fulvous; coxæ, tips of thighs and tarsi pale ochreous: 24 lines long.

Female undiscovered.

Neuter (fig.19) castaneous-black: head finely striated, clypeus with fewer but stronger
striæ ; mandibles ochreous, the teeth and base pitchy. Antenne fulvous, stoutish, con-
siderably clavate (fig. 20), the scape angulated at the base and producing a minute dark
tooth (fig. 20,f). Thorax very rugose, being irregularly sculptured all over, the angles of
the postscutel forming two long divaricating spines, pale at the tips. Petiole stoutish,
basal nodule ovate, truncated behind, second globose, both very rugose : abdomen very
smooth and shining, with short pale scattered hairs, and subferruginous at the apex.
Legs entirely fulvous; thighs and tibiz clavate: length 2 lines.

By the peculiar contour of the scape at the base, which forms a knee producing a mi-
nute tooth in the neuter, and probably is similar in the female, this very distinct species
is no doubt allied to the M. lobicornis of Nylander; but as this tooth is much less deve-
loped than in his Myrmica*, and he says, “ capite, thorace nodisque segmenti primi lon-
gitudinaliter striatim profunde rugosis +,” our insects must be different, for the head of
mine is merely finely striated, and the thorax and both nodules are exceedingly rugose,
but not longitudinally striated.

I red AG ndr and four neuters from a nest in Scotland in July 1825; but I

did not observe any females.

I only know the male of M. cespitum by De Geer’s memoir and figures, and until we

possess that sex, together with undoubted females, I shall not be satisfied regarding our

members of this species, for our neuters do not altogether accord with Nylander’s and

Foerster’s descriptions.. In the British examples, the tibiæ, as well as the thighs, are
pitchy, the head is finely striated, not rugulose, neither will the sculpture of the thorax

216 MR. CURTIS ON THE GENUS MYRMICA,

bear that construction, excepting the postscutel: the profile of the petiole and the spines

given in Nylander's plate * agree, however, very well with our insect.
It is strange that the males of this species should not have been detected in England,

as the neuters are not uncommon, and the females, if such they be ?, have also been found.
These females are so distinct from any other species, that I had given them the name of
maculipes. The form of the head, thorax and nodules is very peculiar,

In the middle of April 1829 I collected some of the neuters at Southend: I found them
at the roots of plants at the base of the cliff, and subsequently in June I met with a small
variety at Darent in Kent. Mr. Smith has found them not uncommon at Sandown Bay
in the Isle of Wight, and also at Folkestone. The two females alluded to, agreeing with
M. Nylander’s M. fuscula, were discovered by Mr. Dale, under a stone at Charmouth in
July, and they had lost their wings.

This species requires investigation. I have a pale neuter, which agrees with one of
Nylander's specimens ; I believe it came from Dorsetshire: Mr. Smith has taken others
on Shirley Common, Surrey ; and Mr. Wing met with several under the bark of an oak-
tree at Brixton the beginning of April. They were all neuters.

10. M. sımıurıma, Nyl. MSS.; Smith's List Brit. Mus. part 6. p. 118.
The neuters of this insect were taken I believe by Mr. Dale in Dorsetshire.

11. M. GRAMINICOLA, Latr. Hist. Fourm. p. 255.

On the 20th of May I took a neuter on a bank at Dinton near Wilton, and I believe it
is abundant under stones on the Downs there. Mr. Smith finds it under stones at Wey-
bridge, Surrey. :
Latreille's descriptions are too vague to enable me, without seeing his examples, to
decide regarding this species. When I published the Genus Myrmecina in 1829, I
thought it possible my species might be the one indicated in the * Histoire naturelle des
Fourmis,' as the wings of the male F. graminicola are described as entirely blackish, and
at that time I only possessed that sex ; but Latreille compares his insect to the F. rubra,
and makes no mention of the difference in the neuration of the wings, which would
scarcely have escaped so acute an observer, especially as he remarks that the nervures
are black; and as our females agree in no respect with Latreille's description, I cannot
think that our insects are identical. M. Foerster seems to be unacquainted with the
neuters and females of M. graminicola, and the male which he describes is undoubtedly

my Myrmecina Latreillü.

This pretty Species is recorded by Mr. Smith as inhabiting moss in Coomb-wood, Surrey.

bark of felled trees and in moss at the base of poplars near Pau, Basses Pyrénées, in
_ January 1853. I am unacquainted with the male, unless it be a Stenamma.

18. M. DOMESTICA, Shuck. ; Smith's List of Brit. Mus. p. 119 *.

This, the smallest of the Ants, is the greatest of all pests, when it establishes itself in
a house, as from its minuteness and activity it insinuates itself into every crevice. My
attention was called to this mischievous creature many years since. Tt was first disco-
vered in London in a bakehouse, and my impression at the time was, that it had been
introduced with foreign maize into this country, which is supported by the fact that it
cannot endure cold +.

There is no difficulty in obtaining the workers, but the males and females are less
abundant, and not always to be found. My specimens of these are not sufficiently per-
fect to ascertain if the neuration of the wings differs materially from the typical species,
but from Mr. Westwood's figures I am disposed to think that JM. domestica is a species
connecting the Myrmicæ and Stenamma.

Male very black and shining; head dull, indistinctly punctured; mouth ferruginous:
antennæ tawny, dusky at their tips, the scape and second joint ferruginous, the latter
stouter than the third; and elongate obconic. Thorax indistinctly and irregularly
striated ; scutel large and glossy ; postscutel convex, delicately punctured, with the angles
scarcely visible. Petiole elongated, basal joint clavate, second subglobose : abdomen small,
ovate-conic, the tip ochreous. Wings with a pale fuscous-yellow stigma, the nervures
almost invisible. Legs long and slender, ochreous-white; the coxæ, thighs and tibiæ
pitchy, except at their extremities: length 13, expanse 3 lines.

Female undiscovered.

Neuter smooth pale reddish ochre: head large, oblong, convex, finely striated, the
margin and clypeus more or less fuscous; mandibles ochreous. Antenne stout, and
ochreous, scape long, second joint stoutish, elongated, third and six following very short,
transverse and increasing in diameter, the three last joints forming a stout fuscous
club. Thorax much narrower than the head, indistinctly striate-punctate, oblong, nar-
rowed at the middle; postscutel producing two distinct acute divaricating dark spines.
Petiole stoutish, with a few hairs, basal joint elongate-clavate, subrugose, second globose :
abdomen small, very polished, with a few short scattered hairs, ochreous, brown beyond
the middle, the apex ochreous. Legs short, stout, and ochreous : length 1 to 14 line.

The male of this species greatly resembles that of S. Westwoodii, but independently of
its smaller size and somewhat different sculpture, the postscutel has only two minute
points, which are scarcely visible; the tarsi, especially the hinder, are white in some
lights, and the nervures of the wings are difficult to discern.

The only evidence I have of the above insects being the males and neuters of one spe-
cies is my having discovered them together. I beat two males and two neuters out of a
Privet hedge, the 31st J uly 1852, on the Folkestone road near Dover. At first I considered
the neuters to be small varieties of Myrmica unifasciata, but on obtaining typical speci-
mens at Pau, the difference was manifest; the dark band on the body of that species
covering more than half the basal segment, whilst the antennæ are entirely fulvous. This
strong resemblance however leads me to think that its male may be similar to the same
sex of our species, and consequently that it may be a Stenamma, as previously intimated.

_ This species, which I dedicated to my esteemed friend Mons. P. A. Latreille, is quite
distinct from any other type of the Formicide that has fallen under my observation. It is
now twenty-five years at least since I discovered the males near that romantic spot, Black
Gang Chine in the Isle of Wight, but I have since found others near Greenwich, towards
the end of August; and at Sandgate in Kent, in October. It was not till August 1836
that I had the satisfaction of taking, what I consider to be, the female of this insect, at
Lulworth Cove. It is remarkable that Mr. F. Smith should have caught a female also in
Camden Town, on the wing, and as he has also found the male at Colney Hatch, it seems
to be generally distributed in the southern counties. It appears to affect swampy locali-
ties, for all the males I have taken were flying about and settling upon rushes, and my
female was captured close to a spot where rushes and reeds were growing.

As it is inconvenient to retain useless names, it is advisable to state that Myrmica
binodis must be expunged from our British lists, and of the eleven Formice recorded in
my Guide*, there are only eight which are ascertained to inhabit Great Britain. No. 2;
F. pubescens, Latr. and No. 8. F. emarginata, Oliv. were admitted on doubtful authority,
and No. 11. F. cognata, Steph., is not to be found in the British Museum, where Mr. Ste-

phens’s collections are deposited.

XXIV. Note on thé Elaters of Trichia.
By ARTHUR Henrety, Esq., F.R.S., ELS. ác.

Read February 7, 1854.

THE existence of spiral fibres in the filamentous elaters mixed with the spores of Trichia
and some allied genera of Fungi, is a fact so remarkable, that, since attention was drawn
to it by Corda, it has been mentioned in almost every notice on the general structure of
the lower Cryptogamia. Had it not been recently called in question by two distinguished
vegetable anatomists, I should not have ventured to occupy the attention of the Society
with the matter, when I have only time and opportunity at present to describe the condi-
tion in a single species. ;

Hedwig the younger (1802) was the first to point out the existence of the spiral fibres, in
three species of * Lycoperdon,’ which Schlechtendahl identifies as Trichia rubiformis, Fries,
T. chrysosperma, Fries, and a Diderma. In looking over the Ratisbon ‘ Flora,’ I find a
passage in a paper written by Kaulfuss, on Turgionia, in 1822, in which that author says,
“according to my investigations, the structure of the so-called capillary tissue of the Tri-
chiaceæ is exactly the same as that which we find in the elaters of the Hepatice.” So
that apparently Corda was the third, and not the second, observer of the fact, as is gene-
rally imagined. Corda first made it known in an essay published at Prague in 1837,
having in the same year brought it before the Association of German Naturalists, '
their meeting in Prague. Schnitzlein has figured the structure in his * Iconographia,
and a notice on the subject, without figures, but asserting the existence of the spiral fibres,
was published by Schlechtendahl in the * Botanische Zeitung’ of May 4th, 1844. |

On the other hand, Schleiden, in the most recent edition of the ‘ Grundzüge der wissen-
schaftliche Botanik,’ says (ii. 41) that observations, recently repeated, have perfectly con-
vinced him that the appearance of spiral fibres arises from the twisting of a flat band ;
while Schacht, in his ‘ Pflanzenzelle,’ declares (p. 151) for the same view. Schleiden
gives no figures, but Schacht draws fragments of elaters from two species of Trichia
(pl. 16. figs. 18 and 14); but his figures completely contradict the statements in the text,
for they give appearances which could not possibly arise from the twisting of a flat band.

Having carefully examined the elaters of Trichia (serotina, Schrad. ?) in some specimens
sent home to the Society by Mr. Ralph, from New Zealand, I am prepared to assert ars
tively the existence of spiral fibres, exactly analogous to thoapan Marchantia polymorpha; .
the number of fibres in an elater of this species of Trichia is three. Corda ABE a
much greater number in some species, but I think that point is open to doubt. e
fibres thin off towards the very gradually attenuated ends of the tubular _
apparently become confluent there, in the same manner as I described in Marchantia

polymorpha (Linnean Transactions, vol. xxi. p. 107), but the ends are so fine that even

222 MR. HENFREY ON THE ELATERS OF TRICHIA.

with a power of 1000 diameters and a good light I could not clearly define the termina-
tions of the fibres.

My observations as to the tubular character of the elaters, were decisive even before
clearly defining the fibres, since I could obtain a transverse sectional view in certain
curved filaments, which gave a circular form; the spiral structure was clearly distinguish-
able with a power of 250 diameters; but, in order to count the fibres, it was necessary to -
take out a few elaters and mount them in the thinnest possible film of liquid, under very
thin glass, and apply a magnifying power of 1000; then the individual fibres could be
made out quite clearly enough to allow of their being drawn with the camera lucida.

These elaters may be regarded as very good test objects for the defining power of the
higher object-glasses ; or, perhaps,—considering the confusing effect of the crossing curves
of the different parallel spiral fibres,—as test objects by which to measure the value of
observations on the more difficult tissues. If we take them in this light, it must follow
that either the microscopes or the observing powers of Schleiden and Schacht are im-
perfect, and since the latter certainly is not the case, the conclusion is that observations
on very highly magnified bodies made by these observers, must be received with great
caution until they provide themselves with better instruments.

Postscript.

Since the above was written I have received some information on the subject from the
Rev. Mr. Berkeley, who fully agrees with me as to the existence of spiral fibres.
Mr. Berkeley directed my attention to the fact that Schmidel (Icones Plantarum) had
pointed out the existence of this structure in 17 62; thus many years before the younger
Hedwig. I may transcribe Mr. Berkeley's remarks on Schmidel’s figure :—« Spiral fila-
ments do not exist in Arcyria Pumicea, the species which Schmidel has in view in tab. 33;
but he has mixed up with it some Trichia, figured in figs. 4, 12, 18, 14, 15, 16; and a
careful examination, with a lens, of fig. 16, and a reference to the text will show that
Schmidel was perfectly aware of the structure." In the copy in the British Museum I
find the spiral fibre of fig. 16 quite clear, without magnifying the drawing.

“ Cribraria purpurea is represented at the lower part of the same plate: no spiral
filament, so far as I have observed, exists in this Species, nor can I, on a re-examination
of the fungus this morning, find any such appearance as that represented by Schmidelat -
fig. 8. Itis possible however that he may have had one of the red Trichie intermixed
with his Clathrus stipitatus, for his description is too circumstantial to allow of a suppo-
sition that so correct an observer could make so palpable a mistake.” Mr. Berkeley
inclosed a specimen of this fungus with the filaments, and I also find no spiral filament.

“ Schmidel did not detect the structure in the species figured at his tab. 24, if that is a
real Trichia.” He here represents the filaments as moniliform (fig. 7). Mr. Berkeley
also reminded me of his own discovery of threads with a single spiral fibre in Batarrea
(Hooker’s Journal of Botany, ii. tab. 22. fig. 1, 1843). |
Mr. Berkeley very truly says in his note, that Schacht’s own figures contradict his text.
He gives a — screwed appearance with three threads, which could not possibly

result from the twisting of a flat band; this could only present two threads formed by its

MR. HENFREY ON THE ELATERS OF TRICHIA. 223

two edges. The appearance of the spiral fibres is very clear with low powers, yet I do not
consider that they are sufficient to prove the actual structure; but a very high power in
my opinion renders it unmistakeable, while the fact of obtaining the free ends of the fibres
in an elater broken across, puts the question beyond doubt.

XXV. Note on the Genus Ancistrocladus of Wallich. By G. H. K. Tawarres, Esq.,
F.L.S. &c., Superintendent of the Botanic Garden of Peradenia, Ceylon.

Read February 21, 1854.

HAVING recently had opportunities of examining the structure of the flowers of Ancis-
trocladus Vahlii, as well as its fruit in various stages of development, I have been enabled
_ to arrive at a more correct knowledge of their structure than appears to have been pre-
viously within the reach of botanists who have described species of this genus, and there
would seem to be now little room for uncertainty as to where the genus should be located.
The circumstance of the fruit of Ancistrocladus being surmounted by the enlarged
segments of the calyx has led to the genus being introduced by different botanists into
the several families of Combretacee, Malpighiacee and Dipteracee; from all these,
however, it essentially differs in its seeds being albuminous.
With the Symplocee it seems to me that Ancistrocladus would associate better than
_with any other group of plants, agreeing with them in its undivided exstipulate leaves,
its character of inflorescence, imbricated calyx and corolla, persistent calyx, stamens
adhering to the base of the corolla, inferior ovary, albuminous seeds and cylindrical
embryo. From Symplocee, however, it differs in its scandent habit, its calycine segments
becoming enlarged, its solitary erect ovule, and the peculiar structure of its albumen.
With the Myristicee and Anonaceæ, Ancistrocladus would seem to have some slight
affinity, its only ovule recalling to mind that of Myristica, and the embryo not being very
dissimilar in the two genera; whilst the scandent habit and uncinate ramuli give Ancis-
trocladus some considerable resemblance to Artabotrys.
The following generic character has been drawn up from an inspection of fresh speci-
mens of Ancistrocladus Vahlii, Arn., and from the figure of Ancistr. Heyneanus, Wall. in |
the last volume of Dr. Wight’s admirable * Icones Pl. Ind. Orientalis.’

XXVI. Remarks relative to the affinities and analogies of natural objects, more parti-
cularly of Hypocephalus, a Genus of Coleoptera. By Joux Curtis, Esq., F.L.S.

| &e. óc.

Read April 4, 1854.

THE number of extraordinary new forms, which have been discovered of late years, has
led to a great deal of ‘speculation regarding their position in the scale of nature. This
has been exceedingly useful and instructive, although often very perplexing, and I fear
that we not unfrequently take the shadow for the substance, mistaking analogies for
affinities. The curious, indeed wonderful insect, which Mr. White exhibited and com-
mented upon at a recent meeting of the Linnean Society, will be my apology for offering
. any remarks upon the subject.

The affinities of natural objects have been supposed to form a chain, a net, or a series
of circles, the last composed of certain definite numbers of types, &c. These ingenious
systems have been ably discussed by talented men*, but they have not made a lasting
impression, owing probably to the multitude of exceptions that occurred and the gratuitous
assumptions necessary to fill up the vacuum occasioned by absent members. We all
know that “the Natural System” has been long an object of pursuit, which I expect we
shall never overtake. The truth appears to be, that there is no perfect natural system,
according to our limited notions; and it will be a stumbling-block to those who think
otherwise, to find that where a few links are forthcoming, which unite certain groups,
there are a vast number more discovered, which disturb what promised to be with
fewer materials a complete arrangement. Thus we have lines broken, circles not meeting,
most curious types presenting themselves to augment infallible numbers, and to be dis-
missed by the theorist as inconvenient intruders. No doubt there is a plan in Creation
which is not revealed to us; but to study, write upon, and understand a subject, we must
form a system (imperfect though it be), in order to methodise and arrange our materials
as they are collected; and to accomp ish this, we must be contented with chains which
are continuous, of unequal lengths, either running entirely parallel, or converging, or
diverging, but forming Stirpes or Families which harmonise, are easily comprehended,
and exhibit various lines of relationship or resemblance. — ~ ! dnm

In searching for a natural system, we seek for perfect unity or harmony, which being

frequently interrupted, we fail in our object, and are disappointed. No doubt harmony,

228 — MR. CURTIS ON HYPOCEPHALUS, A GENUS OF COLEOPTERA.

of their agency, but at all events of disturbing forces, which have apparently succeeded
one another from the beginning of the world, and are active still. We ought not there-
fore to be more surprised at finding systems not to be perfect, than we are to find that
sound is not free from discord, nor form from distortion.

Perfection seems to be equivalent to harmony ; and this as regards form, which most
concerns us at present, was best understood by the Greeks. It consists of a combination
of parts, whose relative proportions are so perfectly in harmony in every respect, that the
object becomes pleasing to the eye, even when uncultivated ; it leads the mind to the
contemplation of a type of grace and beauty exceeding our daily experience, and thus the
Grecian sculpture has become the standard of taste. The human heart is greatly affected
by harmony: Poetry, Music and Painting bear ample testimony to its influence. Order
and arrangement are component parts of harmony, for without them no system could
exist. |

A knowledge therefore of the component members of bodies and the harmonious com-
bination of them is, or ought to be, the basis of all arrangements, and the closer we keep
this in view the more true to nature, and the more satisfactory will the system be, because
it will make everything subservient to true affinities. But in our progress to establish a
system we are sure to find disturbing forces, producing aberrant types of form, which like
discordant notes in music, will not chime in anywhere ; they are too flat for some chords,
too sharp for others, and are thought to be anything but consistent with our notions
of what is natural. Now to this description of animals belongs the anomalous beetle
which Mr. White introduced to us, and which he has been so obliging as to allow me to
examine at my leisure. It has received the name of Hypocephalus, and resembles so many
individual members of different families, yet agreeing with none, that it has from its first
discovery been a subject of speculation, in which M. Desmarest, Dr. Gistl, Dr. Burmeister,
M. Guérin-Méneville and Mr. Westwood have taken part.

I should say, it has the head of a Tortoise, the tusks of a Walrus, the legs of a Kangaroo,
and certainly the strength of a giant; probably a hundred times greater in proportion to
its size than that of an Elephant. Amongst Insects it has been likened to the Mole-
cricket, and so deceptive are analogies, that when I first beheld the Hypocephalus at
Florence, I thought it was a gigantic Brenthus*. M. Desmarest considered it allied to
the Silphide or Grave-digging beetles, and Dr. Burmeister and Mr. Westwood are agreed
that it is allied to the Cerambycide. Were it not for the deficiency in the number of the
palpi, there would be no difficulty in associating it with the Scaritide: the head and legs.
being very like those of Pasimachus, and the antenn® being nearly those of Psammo-
philus; whilst the robust legs, large head, ample postpectus and remote hind legs of
Caladrowm (a New Holland Carabus) at once exhibit a great resemblancet.

_ It is evident, in making any attempt to associate an aberrant form with a natural family,
that great caution is necessary, not to be influenced by-analogy, beyond what it is worth,

* It is remarkable that some of the Brenthide have the hinder angles of the head produced in the male, as in
Arrhenodes, where they form lobes, smaller in proportion, but of the same character as those exhibited in Hypoce-
phalus, which would altogether indicate a similarity of economy.

+ Vide also Clivina, and Broscus; and Promecoderus has quite the form of a pigmy Hypocephalus.

for a single proof of affinity must be preferred before an assemblage of analogies. This
leads me to question the views of my friend Professor Burmeister, regarding the relation-
ship of Hypocephalus with the Prionide, for after a careful investigation I am constrained
to believe, that the former genus is more related to the Lamellicornes, and for the
following reasons, which I will give in a tabular form, the better to contrast the claims of
Hypocephalus to be associated with either of those Families.

The LAMELLICORNES

are Pentamerous.

Mouth with 4 Palpi, quadri- and tri-articulate.
Mandibles often corneous.

Antenne short, capitate, or clavate, often with
many moniliform joints.

Eyes small, round or oval.

. Elytra horny or coriaceous.

Legs, hinder not unfrequently incrassated.

Tibiz thick, dilated, 4 anterior emarginate ex-
ternally, forming teeth or lobes; apex with mi-
nute spurs.

Tarsi simple; anterior short and a little dilated.

The LONGICORNES
are Tetramerous.
Mouth with 4 Palpi, quadri- and tri-articulate.
Mandibles always corneous.
Antenne elongated, not moniliform.

. Eyes emarginate.

Elytra horny or coriaceous.

Legs, hinder not incrassated.

Tibie dilated, generally compressed, not emargi-
nate externally. |

Tarsi, penultimate joint generally bilobed, some-
times with a head, or false joint at the base of
the terminal one. All four-jointed.

All five-jointed.

After this simple comparison, let us take a more general view of the character. In no
family of beetles is the thorax so fully developed as in the Scarabeide, and the legs are
almost universally robust. In Melolonthide, as indeed in all the Lamellicornes, the tibiæ
are more or less lobed or toothed outside*. In Chrysophora and Pelidnota, in Ripsinus,
Dichelus and Pachycnema we find the hinder legs very much larger than the other four ;
the thighs are very much incrassated, the tibiæ often curved and toothed, whilst the
genus Hexodon proves what extraordinary departures there are from the typical forms.
When we arrive at the Zucanide we find a description of mandibles that singularly
accords with Hypocephalus, especially in Pholidotus and Orthognathus, whilst the eyes
are small, remote, and placed behind the antennæ. The labrum and labium are generally

invisible after death, and the maxillary lobes are very small, whilst the palpi are well

developed, as in Platycerus, the typical Lucanide, &c. |
Let us now turn to the apparent likeness between Hypocephalus and the Longicorns. |
In approaching that Family we find Passandra, which, bears some resemblance to Hypo-
cephalus in the form of the head and antennæ, and in ‚the position of the eyes, but the
legs are remarkably small ; Passandra however is considered to form one of the links to

Parandra (which may be termed a tetramerous Lucanus), and making an approach to
Hypocephalus, but the characters of the mouth, eyes, and tarsi; will not support y
claims to affinity t. Next comes Spondylis, which in the form of the antenne and the
proportions of the palpi, agrees with Hypocephalus, but the mentum is not trilobed, the

eyes are dissimilar, the tarsi tetramerous* and of a different character, being all equally
long and dilated. Another genus, Cyrtognathust, is apt to confound our notions of
analogy and affinity, but in truth it bears only a resemblance to Hypocephalus, principally
owing to the elongated head, and the mandibles being bent down like a beak, with lateral
protuberances, and well-developed palpif. For the eyes are very large, and reniform, |
being deeply emarginate, approximating, indeed almost meeting on the crown: the head
is not dilated at the base, having no angles, far less any lobes: the antennæ are very long
and curling, more than half the length of the insect, and 12-jointed, the joints compressed,
completely serrated, the third joint very long: the thorax is broader than long, the sides
angulated, with a large conical porrected spine at the base of the antepectus, between
the anterior coxæ ; the postpectus not unusually large; the cox: approximating in pairs :
the scutellum typical and triangular. Elytra more than twice, in some specimens nearly
thrice, as long as the head and thorax united. Wings ample. Abdomen as large as the
postpectus. Legs very long, stoutish, compressed: thighs stout, but not incrassated :
tibize long, especially the hinder, straight, not dilated nor lobed, but the first pair are
spiny; all with a pair of acute spurs at the apex, longest in the hinder pair: tarsi tetra-
merous, nearly of equal length, the two anterior pair depressed, dilated, and very pilose
beneath, 3rd joint bilobed, terminal joint long and clavate, with a minute spurious joint
forming the base; the joints in the hinder pair with their angles spiny, and two series of
hair beneath: claws long, curved and sharp. It is an inhabitant of Mongolia, consider-
ably to the north of the Equator. !

It would be unreasonable to deny that there is a very considerable analogy existing
between Hypocephalus and Cyrtognathus, but if we look to the antennze having 12, instead
of 11, joints, to their great length and relative proportions, as well as to the situation,
magnitude, and form of the eyes, the size and figure of the thorax, the scutel, sternum
and elytra; having wings for flight; to the long sprawling legs, neither robust nor truly
5-jointed, to the long simple tibiæ, the dilated and bilobed and spongiose tarsi, it is im-
possible to allow that there is any affinity. Cyrtognathus is a Longicorn, Hypocephalus
is not$.

he has adduced another insect, named Baladeva Walkeri, in support of his views.

at the base of each segment. It is 2} inches long* ; the thorax about 10 lines broad.

There are so many differences between M. Desmarest’s figure and Mr. Turner’s speci-
ment, that in all probability they are, if not distinct, the sexes, this being a male I pre-
sume. My descriptions and figures may assist in settling this question, and I trust they
will prove serviceable in illustrating the history of this anomalous beetle, as well as lead
to a careful examination, in living specimens, of the extraordinary apparatus under the
head, which may also be a sexual character. 3

Before further discussing the position of Hypocephalus I will attempt to complete its
history as far as I am able, but at present I can only conjecture its habits by analogy.

Many specimens of this beetle have been found in the mining districts of Brazil, con-
siderably south of the Equator. Three are reported to have been met with in the carcase
of a dead horse, and others creeping upon the ground. It is also stated to live in rotten
wood in forests. There is every reason to believe that Hypocephalus is a burrowing insect,
and probably lives underground. Its attenuated form is admirably adapted to forcing its
wedge-shaped head into any crevice, with an incredible power of resistance in the hind
legs, and its tapering behind is no less calculated to enable it to retreat, folding its enor-
mous limbs by the sides of its small body. Under such circumstances one would expect
to find unusually small antennæ, which readily fall back and beneath the head, for pro-
tection. Wings of course are useless, whilst its connate or soldered elytra give additional
solidity to the body, and their partial separation allows of an expansion of the abdomen,
under great exertion or pressure.

The fore feet, like those of other burrowing insects, are fitted for scraping, clearing
away the refuse, and passing it backward. The lobed jaws probably fit into the wonderful
apparatus at the base of the head, and together with the protuberances on either side seem
to form an instrument for grinding its food, which may then be deposited until required
in the pouch, which looks indeed like a ruminating stomach. The mandibles are formed
for clawing and pulling, or tearing, and the two rows of teeth, like the molars of an ele-

* Mr. Westwood’s specimen is 3} inches long.

+ This example had broken feet, as my figure shows, and probably it was aged, or dead when found; young and

phant, are evidently for grinding or mastication, the jaws by themselves being useless in
that respect, yet I expect they are capable of lateral motion.

Having shown that this pentamerous beetle agrees with the Lamellicornes in various
ways, whilst it disagrees with the Zongicornes in many, I will assign my reasons for asso-
ciating Hypocephalus with the former Family, even were the claims balanced, excepting
the tarsi.

I confess that I have still so good an opinion of the tarsal system of Geoffroy, and
adopted by Latreille, as a basis for the primary divisions of the Coleoptera, that I do not
hesitate to challenge any systematist to exhibit another, better, more useful, or less
objectionable*. Itis usual to term this an artificial System, but that which is based upon
anatomy is no more artificial in Entomology than in any other Class of animals, and the
skeletons of Insects being external, the joints of the legs and feet are as purely anatomical
as the bones (the femur, tibiæ, &c.) of any quadruped or bird. In pursuing the tarsal
system, no one will attempt to deny meeting with many exceptions to the general type of
form, but these occur in the minuter groups, which often seem to become feeble in their
development, and depart from the perfection, if I may so term it, exhibited by the large
and typical species. In the Family Staphylinide, for example, the number of joints
varies in the feet, but this is confined to the minute speciest, and to an amount so small,
that it cannot justify our abandoning so valuable and tangible a character for dividing
the enormous Order Coleoptera. And when we examine the large and perfectly-deve-
loped examples, which must decide the position of a Family, we find the Staphylinide an
undoubted pentamerous groupi; the larve also in this instance assimilating so well
with those of the Carabide, that it is at present difficult to decide to which family they
belong. .

My experience teaches me, that as regards aflinities, animals do not descend in their
claims of relationship, viz. If the types of a group exhibit certain perfections in their
structure, that group has no absolute affinity to a family typically less perfect, and cannot
therefore be transferred to that inferior group, without doing a violence to nature's laws.
For instance, it would be unnatural to remove a member of the Family Carabide, with
its 6 palpi, to any other less perfect, however modified the tarsi might be, or however
strange its contour$. On the same principle, its pentamerous character excludes it from
entering the lines of the Heteromera, or any other of the great sections.

This is my reason for maintaining that Hypocephalus cannot be admitted amongst the
Longicornes: it must find a place amongst the Pentamera. It may be affirmed that the
Tetramera are pentamerous,—this I cannot admit; the portion considered as a 4th or extra
joint, even when articulated, is not the analogue of the 4th joint in the Pentamera; it is

in the anterior feet: vide Phytosus, pl. 718.

merely a head or fulerum at the base of the terminal joint, which is rendered necessary
from the 8rd joint being bilobed and cushioned beneath; but as a general rule I consider
the bilobed joint to bethe penultimate, not the antepenultimate joint, throughout the Co-
leoptera, especially where there is only one bilobed joint* ; and when a joint is either added
or withdrawn, the change takes place at the base of the tarsust. The Heteromera, I think,
substantiate this position, for in the four anterior feet, it is the 4th joint which is bilobed ;
but in the hinder pair it is the 3rd joint which is thus formed, in those species which
are furnished with bilobed joints. Even in the few exceptions, if they be admitted as.
such, we find more than one bilobed joint in the foot, or where it is the antepenultimate,
which it very rarely is, which is altered in structure, it is not bilobed, but cup-shaped or.
sloped off obliquely ; moreover the false joint in the Longicornes is not cushioned beneath
like the 3 preceding joints, which shows it is merely the base of the 4th or terminal joint.

Neither do I insist that Hypocephalus is a Lamellicorn, although I feel a conviction
that it is not a Longicorn. All my claims for it are based on its being truly a Penta-
merous beetle, which draws it nearer to the Lwcanide than it can possibly be attracted
to the Cerambycide, by any less important character. If indeed subsequent discoveries.
should furnish types to unite the Lucanide and the Prionide, Hypocephalus may possibly
assist in such a union, and I am not sure that it would not be more in accordance with
nature, to change the position of the Heteromera in a linear arrangement, and attach
them to the Trimera, with which they have a considerable resemblance. For the Hete-
romera whilst partaking the characters of numberless families, cannot be associated with
any of them.

In changing the position of the primary divisions, we should not abandon. the philo-
sophic and admirable systems of Latreille; and if we suffer ourselves to be seduced. by
analogies to wander from well-established systems, without sufficient reasons, we shall
have eventually to retrace our steps to free science from the difficulties and confusion
in which it has been involved. It is only necessary to review the Heteromera, to see
how dangerous it would be to lose sight of the tarsal system, for in that extraordinary
Section, which seems so distinct from the rest of the Coleoptera, one finds the types of
form of almost every family of beetles, from Carabus to Coccinella} ; and I am ashamed
to confess that when I collected materials for my “Guide to an Arrangement of British
Insects,” I was so captivated by analogies, which was the prevailing taste of the times,

It is twenty years since I first. stated that the Coleoptera were composed of 4 distinct Types (it ought to have Bien
5 lines of form. Vide Brit. Ent. fol. 498), one of which was the Heteromera, which seems to be a croup complete in
itself, and although reflecting all the other Families, being anatomically distinct from them all. 7. : |

that I was led to make some changes which I shall correct on the first opportunity. Indeed
if we were to reject the form of the feet in the Coleoptera, disregarding the number of
the joints, the Heteromera might be distributed throughout the entire mass.

I must not, however, be misunderstood regarding the value of the structure of the
mouth in the formation of systems, for although it may be subject to great modifications,
and depart from the typical forms, like the changes in the tarsi, such anomalies are perhaps
confined to the minuter members of a family, and a comparison of the trophi is unques-
tionably of the greatest importance in arriving at the true affinities of insects. As our
materials multiply our knowledge advances, and changes become necessary and unavoid-
able, but let them be made on substantial grounds, not losing sight of the first principles
of true affinity.

I trust that those from whom I differ in opinion will be assured, that it is from no love
of opposition that I have ventured upon this difficult subject, but with the sole desire of
arriving at the truth, and to assist in fixing our Systems on some firm basis, generally
understood, and universally to be adopted, so that we may no longer be tossed to and fro,
as we are at present; every new work, unscrupulously changing, sometimes entirely
reversing or disregarding, the labours of the most profound and learned men of science,

that have adorned the pages of Natural History.

XXVII. On the Osteological relations observable among a few Species of the Bovine Family.
By WALTER Adam, M.D. Communicated by RoBERT Brown, Esq., V.P.L.S.

Read June 6, 1854.

IN a communication formerly submitted to the Linnean Society *, an attempt was made
to trace throughout one large animal the identities and variations of osteological dimen-
sion characteristic of a species. The animal selected for that inquiry was the Camel of
Bactria.

It is now intended, by an osteological comparison of some species in a cognate group of
animals, to exemplify the more striking resemblances and deviations in form which are
exhibited among the components of a zoological family. The indulgence of access to the
British Museum has enabled the writer to examine at leisure nine osteological specimens
contained there, of the Mammalian family of Bovines; three pairs, male and female :—
the Bos Bantiger of Java, the Bibos Gaurus of Nepal, and the Bison of North America;
along with three separate males,—the Aurochs (Bison) of Lithuania, the Caffre Buffalo
of the Cape of Good Hope, and the Short-horned Buffalo of the Gambia, the last a young
animal. The Bovines, equally with the Camel, seemed deserving of study, on account of
their value to Man. :

As a standard of measurement within the animal itself, the basilar length of the
cranium was found to be most eligible in the Camel; the same dimension, similarly
divided into 72 parts, has been continued in the Bovines. Though no single dimen-
sion can be assumed to be invariable, the basilar length of the cranium, notwithstand-
ing its rostral termination in the intermaxillaries, will admit of preference in many other
animals. : |

The breadths of the head in the Camel occupy three sets of distances from the mesial
plane, ending with the greatest breadth—the orbital. Subsequent to those three dimen-
sions of breadth there are four cranial lengths, beginning with the shortest—the palatal.
"Thus placed in order, the seven dimensions of the head in the Camel are by six equal
decrements successively reduced from the greatest length. Bovine species being nume-
rous, with a corresponding scale of diversity, indications of a fixed normal type could not
in Bovines, as a family, be so decided as in the almost solitary Camel. Bovine osteolo-
gical dimensions will be seen to vary not a little. From size of parts—not always greater
in the male—the male and the female bones might even be thought to belong to animals
quite distinct. Still the cranial lengths of the Boyines, without such regular progression
as in the Camel, show a degree of similarity. In all, the length of the head approaches,
in the Gour it attains, the cranial extreme of the Camel. The very different character of

* Linnean Transactions, vol. xvi. p. 525.

238 DR. ADAM ON THE OSTEOLOGICAL RELATIONS

profile in the Camel is owing to the backward position of the nostrils. In the Gour the
fulness of the inion brings the corono-nasal length almost to an equality with the basilar ;
so that the lengths of the cranium, beginning with the coronal, which in the Camel are
5.7.6, may in the Gour be stated to be 6.7.6. In general, among the other Bovines,
especially the males, the basilar length of the cranium, as in the Camel, is intermediate
to the elongation of the muzzle and the recedence of the nasal bones; the palatal length
also reaches nearly two-thirds of the basilar length.

Continuing the profile: Bovines have no prevailing height of cranium. In the vaulted
crania of the Aurochs and the North American Bison the inion is even lower than the
nasal bones are over the palate. The inial elevation of the other species may be stated to
be one-third more than the palatal. Compared with the lengths of the cranium, the ten-
dency of the palatal height in Bovines is to be one-third of the basilar length. While
the vaulted crania, as has been already noticed, sink iniad, the crania of Bovines, which
are flattened over the palate, rise to an inial elevation of one half the basilar length. In
the male Bantiger the inial height is half the corono-nasal length.

The greatest similarity of wideness in Bovine crania seems to be at the zygomatic arches,
where the span of the cranium is exactly, or very nearly, half the basilar length. The
muzzles also have a strong resemblance in breadth, that dimension being in all of them |
more than one-sixth of the basilar length. "The broadest muzzle, that of the Cape Buffalo,
is exactly a fourth of the basilar length ; thus in identity with the cerebral transverse of
the cranium. The Aurochs is most conspicuous for wideness of cranium. Next to the
Aurochs are the North American Bisons, male and female. In these two species the
greater breadth seems to compensate for the smaller height. While in the other Bovines
the tendency is to an orbital breadth half the basilar length, the orbits of the Aurochs
reach laterally beyond two-thirds of the basilar length, and their expansion is not much
less in the North American Bisons.

The horns even show a determinate correspondence with the rest of the osteological
structure. The capacious circuit that surmounts the head of the Gour, spreads out, in the
fully-developed male, to twice the basilar length of the cranium.

The mesial extent of the Bovine vertebree, from the occipital condyles to the root of the
tail, closely approaches four times the cranial basilar length. It is accurately so in the
Aurochs, the North American Bisons, and the female Bantiger. Of all the nine Bovines,
the Aurochs and the North American Bisons bave the greatest extension of the dorsal ver-
tebree, as there is of the cervicals in the female Bantiger. The vertebral growth of the
under-aged Gambian Buffalo had been with the sacrals, lumbars and dorsals, in the pro-
gression 2.4.8. |

Of Bovine ribs, the longest fully attains, or somewhat exceeds, the extreme cranial
length. In like manner, the first rib corresponds with the palatal length, slightly exceed-
ing it in those robust species, the Aurochs and the Cape Buffalo. Ju

In no Bovine was there found a perfect identity of dimension between the scapula and
the pelvis, except in the female of the North American Bison. 'The Aurochs and the
North American Bisons, both male and female, have the longest scapule. The scapulæ,

in their length, seem to be referable more to the basilar than to the extreme of the cra-
nium. On the other hand, the length of the pelvie bones does correspond with the
cranial extreme.

In its transverse dimensions the enclosure of the pelvic cavity has no marked identity
with the transverses of the cranium. The ischial transverse has some relation to the
coronal, or to the extreme, lengths of the head. At the same time, the ischial transverse
dimension is very nearly the same as the acetabular, the slight excess of the ischial over
the acetabular in the males being reversed in the females. In the young Gambian Buf-
falo the acetabular development had been more rapid than the ischial.

There is a considerable diversity in length of limb among Bovines, as much in regard
to the atlantal limbs compared with the sacral,,as to the separate bones of the limbs com-
pared with each other. Except in the male Bantiger and the Gambian Buffalo, the hu-
merus is in a small degree shorter than the radius; while there is more excess of length

_ in the femur over the tibia. The male and the female Bantiger show a difference almost
beyond what is specific. In Bovines generally the atlantal extremities are curtailed of
the proportion of the longer sacral bones by from a third to a half of the basilar length of
the cranium.

XXVIII. Observations on the Structure of fa and Peculiar Form of the Embryo
in the Clusiaceæ. By Jous Mink, Esq., F.R.S., F.L.S. &e.

Read June 20 and November 21, 1854.

‘THE object of this paper is to present to the notice of the Linnean Society some remarks
upon the seed of the Clusiacee, and to call the attention of botanists more especially to
the structure of its embryo, the nature of which has been hitherto quite misunderstood.
During my residence in Brazil, I made several observations upon the plants of this family :
the many novel facts thus collected have since induced me to extend this inquiry, with a
view of determining the true affinities and limits of the Order, and of establishing the
characters of its several genera, concerning which our present data are greatly confused
and imperfect. The evidence upon these more general points will, however, be reserved
for a future occasion; my attention, as a matter of primary importance, being first
confined to a consideration of the seminal structure of the family.

The earliest description of these features I find in Jussieu's * Genera Plantarum,
p. 255, published in 1789, where, in his ordinal character of the Guttiferæ, he simply
states that its embryo is erect, without albumen, and with hard corky cotyledons (lobis
suberoso-callosis). "

The next mention is in 1791, by Geertner, who in his justly celebrated work ‘ De Fruc-
tibus, &e., plate 105, figures, with his usual fidelity, his analysis of three species of
Garcinia; these he describes (vol. ii. p. 105) as having a coriaceous testa, a thin integu-
ment, and a fleshy solid nucleus, which exhibits in its axis an apparently different
development of a terete, sometimes compressed, lanceolate form, the whole nucleus con-
stituting a compact inseparable mass : from these facts, contrary to the opinion of J ussieu,
` he infers that the great body of the nucleus is a large albumen, and that the axile portion
. is a pseudo-mono-cotyledonous embryo, closely united together in one solid body.
Richard in 1811, in his excellent memoir on Endorhizal embryos *, in order to mark
the difference between the embryonal strueture of the Monocotyledones, and certain
peculiar macropodal forms observed in the seeds of some dicotyledonous plants, described
and figured the structure of the embryos of Pekea (Caryocar) tuberculosa and Clusia
palmicida. The former has been copied in every botanical work published since that
time, in order to serve as an example of that peculiar development, but the latter has
never been alluded to, or mentioned, in any such work, that I can find; indeed the fact
appears to have escaped the recollection of every botanist who has written upon Guttife-
rous plants, except Jussieu, although it would have been important to have borne that
cireumstance in remembrance. Richard there correctly describes the seed of Clusia as
being enveloped in pulp; one extremity of its brittle testa is pierced with an aperture,
beneath which the nucleus exhibits a small protuberance cleft in two, which he states to
be two minute cotyledons, the principal mass of the embryo being an IR radicle ;
he points out the existence of an inner integument, one end of which is attached to

* Ann. du Mus. xvii. 456. tab. 9 & 10.

244 MR. MIERS ON THE STRUCTURE OF THE SEED

the aperture in the extremity of the testa, the whole nucleus forming, in his own peculiar
technology, “an epispermic antitropal embryo." There is, however, one essential error
in this otherwise correct description ; like other botanists, he has mistaken the base for
the apex of the seed.

Jussieu, in 1813, in a memoir upon the characters of the Hypericine and Guttifere,
drawn from the structure of their seeds*, observes, that if the remarkable fact above
recorded by so accurate an observer as Richard, be exact, Clusia cannot belong to Gut-
tifere, but must constitute the type of a distinct family nearer to the Maregraaviacee.

Choisy, in 1822, in a memoir upon the family of the Guttiferæt, ascribes in its ordinal
character features altogether different from those of Jussieu, and equally opposed to the
description of Gærtner. He states that the seeds are without albumen, that the embryo
is erect, and that the cotyledons are large, fleshy, either separable or combined in one
mass. In Garcinia, he says, the seeds are arillate, and the cotyledons thick and con-
joined; but in Clusia he declares that these presumed cotyledons are separable, a feature
that no succeeding botanist has verified. He alludes in no way to the very different
structure recorded by Richard, of the seed in Clusia, although, when he stated the
separability of the cotyledons in that genus, this idea may probably have been derived
from some indistinct recollection of the analysis of that eminent carpologist.

The description of the Guttifere in DeCandolle’s celebrated * Prodromus? (1824) is
_ confessed to be a mere recapitulation of the above-mentioned memoir, and consequently
the same characters are there repeated upon the authority of Choisy.

Cambessédes, in a very able essay upon this Natural Order, and on its relation to the
Ternstremiacee, published in 1828 1, affirms that throughout the family of the Guttifere
“l'embryon est droit, les cotyledons sont grands, épais, très entiers, soudés ensembles ;
la radicule est très petite, en forme de mamelon; sa direction, relativement au point
d'attache de’ la graine, mérite la plus grande attention, et démontre jusqu’à l’évidence,
que dans les familles les plus naturelles, les caractères, considérées dans la plupart des
cas comme de la première valeur, peuvent varier dans les genres d’ailleurs extrêmement
voisins. Dans le Clusia Criuva, dont je possède des graines dans un état parfait de
maturité, la radicule est tournée vers l'extrémité de la graine la plus éloignée du point
d'attache.” I shall presently demonstrate that this statement is founded on error, and
that the inferences above drawn are illusory. In that memoir the embryos of Clusia and
Calophyllum are described as being erect, inverted, the small mammæform point, which
he calls the radicle, as being at the apex or opposite extremity to the basal hilum of
attachment; while in those of Mammea and Mesua, the radicle is said to be small, and
pointing in a contrary direetion, that is to say, to the basal point of attachment.’ He
therefore erroneously concludes, that in this family the embryo is either homotropal or
antitropal, or in other words, that the radicle is sometimes directed to that point of the
seed next the hilum, at others, towards the, opposite extremity. It is, however, fair to
mention that he had not confidence in the correctness of these observations, and stated
his doubts on this point, for the guidance of future botanists. nes! |

AND PECULIAR FORM OF THE EMBRYO IN THE CLUSIACEÆ. 245

In the following year M. Cambessèdes minutely described the several Guttiferous
plants collected by M. Aug. St. Hilaire, in his journeys through Brazil (Flor. Bras. Merid.
i. 314 ef seq.), and there, in his character of Clusia Criuva, he thus defines its seminal
features: “raphe ab hilo ad basin seminis ducta parüm elevata; radiculà brevissimá,
mammreformi, basin seminis hilo contrariam spectante, cotyledonibus coalitis apicem semi-
nis hilo proximum spectantibus." Little dependence, however, can be placed upon this
ample and precise definition, especially in regard to the terms base and apex, because, as I
shall have occasion to show, in the figures 8, 9 and 10 of plate 65 of the work referred to,
the seed is placed in a position diametrically opposite to that in which it is attached to
the placenta, as the point he there assumes to be the radicle is said to be inferior, and
the stipitate or basal support is there represented as an arillus that covers the apex of
the seed. It is necessary to bear these circumstances in remembrance, as there is here
an evident misconception of the whole structure.

Prof. Kunth, in his details of the several Guttiferous plants collected in the Voyage of
Humboldt and Bonpland, throws no light whatever on this portion of the subject.

Doctor Von-Martius, in his admirable work (Nov. Gen. et Spec. Pl. Bras.), offers no
account, either in his generie or specific descriptions, of the several Guttiferous plants
there enumerated, as far as regards the nature of the seed ; but he gives ample details of
a plant resembling his Olusia insignis, and named by him Platonia insignis, figuring at
the same time the analysis of its fruit and seed. The nucleus enclosed within the testa is
there described to consist of a large mass of fleshy albumen, containing numerous oil-
cells, and enclosing in its centre a long terete or club-shaped embryo, with a superior
radicle, the whole consolidated into one integral inseparable mass. As this form of
embryo, and the presence of copious albumen, were facts opposed to the generally received
conclusion of botanists, in regard to the structure of the seed in Clusiacee, he suggested
the propriety of placing his new genus Platonia in a distinct family, which he proposed
to call Canellacee, thus associating it with the little-known Canella alba, a plant greatly
differing from it in habit and floral structure, and of which we possess an imperfect
knowledge, especially of its carpological features.

Endlicher, in his ‘Genera Plantarum,’ gives the characters of the Order and of each
genus of the Clusiacee, in accordance with the views of Cambessédes, and arranges Pla-
tonia, after Von Martius, in the Canellacee, as a suborder of the Guttifere.

Pöppig, in his ‘ Nova Genera et Species,’ although he details the characters of several

genera and species of Guttiferous plants from Peru and Northern Brazil, and figures some
of the structure of the seed.

of them, does not enter into any description L ;
Prof. Lindley, in his * Vegetable Kingdom,’ where he gives an outline of the ordinal

characters of the Cusiaceæ, adopts the views of Cambessèdes in regard to the nature of
the seed, notwithstanding that he admits Platonia as a member of the family. s

232), follows the example of Cambessèdes in misconceiving the structure of the seed, for
he describes the embryo as having fleshy plano-convex cotyledons, and a very short radicle.

246 MR. MIERS ON THE STRUCTURE OF THE SEED

some little-known American plants of this Order, gives many interesting observations on
the organography, affinities and subdivisions of the family, as a prelude to a review of the
various genera and differential characters existing between them. It is, however, singular,
that in a memoir of such length, where he discusses fully the general structure of the
Order, he does not make the smallest allusion to the important question of the nature of
the seed, concerning which so many uncertainties and incongruities are known to exist:
this is the more remarkable, because in the interval of nearly thirty years since the appear-
ance of his previous memoir, the facts subsequently published are at variance with his
former views on this subject. :

As the results of my inquiries are widely different from the conclusions of Cambessédes,
which have been almost universally adopted by botanists, it will be better to select from
my several observations the analysis of the fruit of a species closely allied to the Olusia
Criuva, Camb., upon the examination of which that able botanist. principally relied, in
the construction both of his ordinal and generic characters. Here the fruit is an oval
drupaceous-looking capsule, 10 lines long and 8 lines in diameter; it is 5-celled, with 5
very thick fleshy valves, whieh break away by their margins from the edges of the par-
titions, and become rotately expanded, leaving a large erect 5-winged column, in the
angles of which the seeds are fixed. Each cell contains about 12 seeds, enveloped in a
thick mucilage, and these are attached horizontally by one extremity to the placentary
column, in two longitudinal rows. The seed is of an oval form, about ith of an inch in
length, and is slightly gibbous on the upper or dorsal side, the lower or ventral face pre-
senting a prominent keel, extending from the base to a swollen point near theapex. The
external tunic, at first thick and fleshy, and of an orange colour, forms when dried a thinner
tough skin, and when it is scraped off, the keel seen on its ventral face is found to cover
a bundle of fibres in the form of a raphe, one end of which proceeds from the stipitate base
of the covering and the point of its attachment to the placenta, as well as to the body
which it encloses, the other end terminating near the summit by a sudden reflexion,
where it enters an aperture through the crustaceous integument of the seed : this is a
hard, brittle shell, striately punctate, of an oval form, and a little flattened at the base,
where, somewhat excentrically, is seen a very small point or cicatrix at the origin of the
raphe-like cord: on the contrary or apical extremity, always somewhat on the ventral
side, and around the opening through which the raphe-like cord penetrates the shell, is
observed a prominent ring, radiately striated, forming a hollow cup: this outer shell is
smooth within, and lined with a very thin free integument, that is contracted near the
summit by a narrow neck of a darkish colour, by which it is suspended and connected
with the extremity of the raphe-like cord: the solid nucleus filling the cavity of this
integument is of a pale greenish colour, marked by numerous very distinct, prominent,
parallel and longitudinal lines of an orange colour, which do not reach the base, but ter-
minate round a flattened colourless space, like that seen in the outer shell, and in the
middle of which a minute shining tubercular point is observed : the apex of the nucleus
is distinguished by a short hemispherical nipple-shaped protuberance of a smaller
diameter, which is divided to its base by a distinct transverse cleft into two equal portions,
the bottom of this commissure on the ventral side corresponding with the dark-coloured

AND PECULIAR FORM OF THE EMBRYO IN THE CLUSIACER. 247

neck of the inner integument, as well as with the somewhat lateral aperture in the outer
shell, and the termination of the cord already described; on making a longitudinal section
of the nucleus, this cleft is more distinctly seen, and at the bottom of this commissure is
observed a small prominent point, and also in the axis extending from this spot to the
small tubercular point at the base is seen a continuous line, more or less narrow, some-
what curved, and of a more opake and whiter colour than the body of the nucleus: the
principal mass is of a semi-crystalline hue. |

This internal thickened line is what Geertner considered to be the embryo of the seed,
and the fleshy surrounding mass to be copious albumen. Choisy, Cambessèdes, and most
other botanists, have considered the main body of the nucleus to be two large cotyledons
agglutinated into one solid mass, the line of their junction being indicated by the curved
line just mentioned, while they held the nipple-shaped protuberance to be the radicle.
In the description above given, I have been careful to avoid the use of technical names in
. designating the several parts, until the whole evidence has been stated; but the inferences
I have drawn from these facts, which I will here endeavour to substantiate, are, that the
seed is enveloped by an entire arillus, with a raphe extending from the hilum, or basal
point of its attachment to the arillus and placenta, to the process or cup-shaped ring
surrounding the aperture situated near the geometrical apex of the ‘testa, and through
which the nourishing vessels of the raphe pass, to unite with the inner integument: the
small cicatrix at the opposite extremity of the testa, near the hilum, must be considered
as the micropyle. Most botanists will perhaps call this extremity the base of the seed, and
correctly so, although others have considered the geometrical apex as the true base, because
it was once the base of the ovule before it became reversed in its position by its anatropal
development: the use of this term, unless accompanied by an explanation of the sense in
which it is applied, leads constantly to error and confusion*. The existence of the internal
chalaza in the contracted and thickened summit of the inner integument, and its connexion

* Great mystification is often created by the misapplication of the several terms umbilicus, hilum, apex or base of
the seed, which are used in a contrary sense by different botanists ; and even Richard, who may be regarded as a koding
authority on this point, is not free from similar confusion. St. Hilaire, in his Monograph on the Brazilian Piolacen
(Mém. du Mus. xi. 446), accurately describes the structure of the seed in Viola to be carunculate at the point y its pla-
centary attachment, which he calls the “ umbilicus,” and the corresponding point of the testa, ithe “ hilum, - which
the inferior radicle is directed, while the areolar “ ehalaza ” is seen at the opposite Lure de or “apez.” Prof.
Kunth, on the contrary (Nov. Gen. et Spec. v. 368), describes the seed in Viola as being carunculate at the apex by
which it is attached to the placenta, with a basal chalaza at the opposite extremity : the embryo is seid to be inverted,
with its superior radicle directed to the hilum. Here we observe that two of the highest authorities apply the same

terms in a directly opposite sense ; the one truly, as regards the point of the placentary n the - con-
sidering that point as its base, whatever be its position in respect to the axis of the fruit : the other -uses the same
terms relatively to the direction which the seed may bear in regard to its position the axis of the pericarp, which
in the instance of Viola, being suspended from the placenta, gives a reversed attitude to all its several parts : if this

loose glossology were admitted, how could we define the base and apex of the seeds, where they sometimes happen to

be erect, horizontal, and pendent in the same cell ? i uie i
Cambessèdes has fallen into an error of a similar nature in reversmg the position of the seed in his representation

of Clusia Criuva (Flor. Bras. pl. 65. figs. 8, 9 & 10), where the stipitate support is miscalled and delineated as an

apical arillus, and his radicle (the true cotyledons) are seen at the base, instead of the apex of the seed.

248 MR. MIERS ON THE STRUCTURE OF THE SEED

with the raphe through the diapyle* or aperture in the testa, constitutes an important
feature in this inquiry. The nipple-shaped protuberance in the summit of the nucleus,
hitherto taken to be the radicle, appears to me, without the smallest doubt, as was first
shown by Richard, to be the two cotyledons of the embryo, which, although small and
short, are nevertheless quite distinct, and their relative position is indicated by the direc-
tion of the cleft, being placed right and left of the axis, or with their commissure pointed
to the raphe: the main body of the nucleus, instead of being the confluent cotyledons, as
hitherto supposed, must be a gigantic radicle, in the axis of which is imbedded the caulicle
of the embryo, shown in the opake central line previously mentioned, terminated at its
base by the shining speck before described, and at its apex by the plumule, which is seen
protruding into the space at the bottom of the cotyledonary cleft. The minute external
speck, which I consider to be the germinating point of the caulicle, is always more or less
prominent, and of a green colour in the living state: this point does not exactly corre-
spond in position with the micropyle of the testa, but is somewhat lateral in respect to it, .
and nearer the basal origin of the raphe. 4
Although this axile portion of the radicle is plainly distinguishable in numerous other
less prominent cases, it has never been distinctly noticed. In Pekea the superiorly
exserted portion of this process has been called the caulicle +, a name also given to the
large germinating protrusion in the embryo of Rhizophora, but inappropriately, because
that term is applicable only to the ascending system, or the elongating portion of the
plumule above its junction with the cotyledons: all below this point belongs to the de-
scending system, and in order to distinguish it from the main radicular mass, it may be
called the neorhiza: it is in fact the growing portion of the elementary root, the more
external mass of the radicle being inert, or at least serving only the purpose of albumen
or of large fleshy cotyledons, in affording nutriment to the germinating parts of the -
embryo }.

* This word is proposed to denominate the distinct aperture often seen pierced through the substance of the osseous
testa, and by which the raphe penetrates, to unite with the chalaza of the tegmen or inner integument of the seed, and
is used in contradistinction to the foramen, a term applied to the orifice of the primine of the ovule, which afterwards
becomes the mieropyle of the seed : this last, in seeds produced from anatropal ovules, is situated at the extremity
always opposite to that in which the diapyle is placed. In the case of Clusia above detailed, the diapyle is a very
manifest aperture, filled with soft fungous matter ; in some other cases it is closed by the osseous deposits of the testa,
and is only recognizable as the point where the extremity of the raphe, when it is free, penetrates the testa. This
must not be confounded with the omphalode, a term applied by Turpin to express the aperture in the centre of the
hilum in antitropal seeds through which the nourishing vessels pass to promote the growth of the embryo ; nor with the
- caruncula, a name used to express indiscriminately any excrescence or swelling upon the testa, whether about the
strophiole, about the hilum, or about the micropyle, where, according to St. Hilaire, it is sometimes observed, as in
Euphorbia, Ricinus and Polygala.

+ This term (synonymous with the tigel/e of the French botanists) is vaguely applied by some authors: thus Gau-
dichaud (Recherches sur l'Organographie, &c. p. 39) defines “la tigelle, ou ce qu'on nomme ordinairement la radicule
dans les embryons; cette partie sert à la composition des tiges." By this is evidently meant only that ascending
portion of the collar of the embryo, which I have above defined as the true caulicle, and which does not belong to the
radicle, although continuous with it.

t It may be maintained by some, that Gærtner’s view is correct in considering the great body of the radicle as an
albumen, and the neorhiza as the radicle, both agglutinated into one mass; but this argument will not hold good,

AND PECULIAR FORM OF THE EMBRYO IN THE CLUSIACEE. 249

I have already alluded to the existence of two somewhat different developments of the
seed in the Clusiacee; the foregoing description affords an example of the one which
includes all cases (as in the tribe Clusiew) where a number of seeds are formed in each
. cell of the ovary, and where they are attached in a horizontal position by their base to
the axile placenta. The other development occurs in those instances (as in the tribes
Tovomitee and Garcinieæ) where only one seed is formed in each cell, and where this is
fixed to the axile column in a vertical position by its ventralface. For reasons that will
be offered in another place, I propose to exclude the Moronobeæ and Calophyilee from
the Order. In the first case (the Clusiec), the raphe, enclosed within the fleshy arillus,
is seen to extend from the base to the apex of the seed, and is free from the testa; in the
second instance the testa is thinner and more membranaceous in texture, and enveloped
in an overlapping arillus, which is thicker and more membranaceous in substance; it has
a large hilum upon its ventral face; the raphe, less discernible, is imbedded in the sub-
_ Stance of the testa, where it spreads into numerous branching nervures, conspicuously
extending over its surface: in the Garciniee we find a similar testa, enveloped in an
entire, copious, more or less mucilaginous pulp; tolerably good figures of this develop-
ment are given by Gærtner in plate 105, illustrating the seeds of Garcinia, and in several
plates of Dr. Wight’s ‘Icones.’ Were it not for the explanation afforded by the analysis
of the Clusiec, the structure of the embryo in the other tribes, Tovomitee and Gareiniee,
would not be so easily understood. : During my residence in Brazil, I examined in a living
state the fruit and seeds of different species of Zovomita, Commirhea, and more especially
of a plant which I have called Lamprophyllum letum, the type of a genus very distinct from
. Garcinia, and comprising numerous species of South American and West Indian origin,

among them the Calophyllum Calaba of Linnsus, and others associated with Gareinia
and Calophyllum, which last genus I consider to be foreign to the Order. The analysis of
the seed of Lamprophyllum will afford a good example of the second mode of development
above referred to. "The drupe is here about the size of that of Calophyllum Calaba, as
figured by J. acquin (Stirp. Amer. tab. 165), and contains generally two, or often by abortion
a single seed, about the size of the kernel of a hazel-nut, which is enveloped in a thiek
mucilaginous pulpy arillus: the testa is thin and brittle, marked by numerous veins
branching from the ventral hilum, and it contains a solid nucleus of a firm and somewhat
fleshy consistence, exhibiting in the apex a minute prominent nipple of the size of a very
small pin's head, seated in a deep hollow depression, a little below the summit towards
the ventral face; near the base, somewhat on the dorsal side, is seen another smaller
speck, which is green and shining, exactly like that described in the nucleus of the
Clusiee. On making a longitudinal section, the main body of the nucleus is seen to be of
a pale sulphur colour, studded with numerous small oblong ducts, whieh, when thus cut,
copiously exude a deep yellow viscous juice: a slender terete neorhiza, exactly resembling

because we see in the Clusiee that the neorhiza is traceable only to the nascent point of the plumule, that the eotyledons
are wholly exserted from and an extension of the main body, and that many of the striæ or Jong tubular ducts, which
extend from the base to the apex of the mass of the nucleus, are carried VE interruption along “ie outer face of
the cotyledons, proving the continuity of the one with the other; for were it of the nature of albumen, it would be in

the form of an investiture of the embryo, not a prolongation of it.

250 MR. MIERS ON THE STRUCTURE OF THE SEED

that observed in the seeds of the Clusiec, is seen in the centre, somewhat oblique with
the axis, one extremity of which terminates in the minute nipple near the apex, and the
other in the basal speck before mentioned : this latter spot is without doubt the germi-
nating point of the root, the apical nipple is the plumule, the main body of the nucleus
must be the radicle, and the cotyledons at first sight appear to be altogether wanting;
but on examining more attentively the minute nipple-shaped process, this is seen formed
of four diminutive fleshy imbricated scales, surrounding a central prominent point, which
is concealed by the two inner and larger scales; the two outer decussating scales thus
separated from each other, are smaller, shorter, and placed right and left of the ventral
face, as in the cotyledons of the Clusie@. This structure is so minute, that it requires the
aid of a strong lens to distinguish it. It may be said by some, that the two outer scales
form part of the plumule, and in such case the embryo would be truly acotyledonous ;
but it appears to me that they ought to be considered as the real cotyledons, not only
from analogy, but because they agree in position with the cotyledons found in the Clusieæ,
with their commissure directed to the ventral face. I have elsewhere pointed out the
analogy of this structure to that of Caryocar, and it constitutes a curious physiological
fact. The absence of cotyledons has long been recorded in plants of a low order of deve-
lopment, and is known to occur also occasionally in exogenous plants among those which
are almost leafless, such as Ouscuta, Vohiria, &c., whence it has been argued, that the
abortion of the cotyledons in the embryo is indicative of the future absence of leaves in
the plants produced by the growth of such seeds. In the case of the Clusiacee, however,
where the floral structure is of the highest order of development; belonging frequently to
the largest trees of the tropical forests of both hemispheres, with copious foliage, large
fleshy leaves, and rich in mucilaginous juices, the absence of cotyledons in the seed, or
their reduction to microscopical proportions, offers an anomaly suggestive of many con-
siderations upon the nature of the organs of vegetable reproduction.

This same internal structure of the seed occurs in every instance I have examined, and
is confirmed by all the evidence obtainable from recorded authority, so that little doubt
can exist that it is constant throughout the Order, with the exception of genera, which,
for reasons to be mentioned in another place, I propose to exclude from the family. The
evidence here alluded to exists in the drawings of Gærtner, to which I have already
referred; in the rough sketch given by Plumier in his ‘ Pl. Amer.’ tab. 257. fig. g, h, i,
which shows a similar structure in the seeds of Rheedia, lateriflora; Dr. Graham also thus
describes the seeds of Hebradendron gambogioides, “cotyledons thick, cohering in an
uniform cellular mass, radicle central, filiform, slightly eurved," a structure which, though
described in other terms, is substantially the same organization that I have related; Dr.
Wight, in his admirable * Icones,” gives other examples of a similar structure, in plates 118,
192 and 960; and Dr. Roxburgh exhibits the same facts in his ‘Coromandel Plants.
These are the only positive details I find upon record, except the analysis of Calophyllum,
. to which I will revert at another time. All accounts therefore confirm the constant pre-
sence of that peculiar development in the axis of the solid nucleus of the seeds of the
Clusiacee, which I have characterized as the neorhiza of the embryo; for our decision
upon this point will determine the nature of the other parts of the nucleus, to which such

AND PECULIAR FORM OF THE EMBRYO IN THE CLUSIACEÆ. 251

various attributes have been assigned. This determination is fortunately assisted by the
drawings of Dr.Roxburgh,whose details, always accurately observed, are copied byDr. Wight
in his ‘ Icones,” where in pl. 192. fig. 12 & 13, is shown a seed of Xanthochymus dulcis,
in a state of germination, together with a longitudinal section of the same: here is
depicted precisely the same linear process (the neorhiza), which is throwing out a root
from the basal speck I have described, while the apical nipple of this same process has
simultaneously become extended considerably, carrying upward with it the leaflets of the
growing plumule: from the lower part of the neck thus protruded, and beneath the two
lower scales which I have designated as the cotyledons, a second rootlet is seen to sprout,
tending first horizontally and then downwards. We have here unquestionable proof that
the process in question is what I have called neorhiza ; for were it the embryo imbedded in
albumen, as Gærtner affirms, it would not throw out descending shoots at the upper por-
tion as well as the base; nor would the same result follow if it were the radicle, according
to the view of Dr. Graham. The fact is certainly fatal to the conclusions of Choisy,
Cambessèdes, and other modern botanists, that the great mass of the nucleus consists of
' two confluent cotyledons, and that the mammæform apex seen in the seed of the Clusiee
is its radicle, even if this opinion had not been disproved by the structural appearances
which I have already described, and which are still further confirmed by a more minute
examination of its internal organization. __ |

On placing a thin transverse slice of a seed of Lipophyllum (Clusia, Camb.) under the
microscope, it will be seen to be of a reticulated texture, and composed of a number of
small hexagonal cells filled with yellowish grumous viscid matter, except in the centre,
across the line of the neorhiza, where the cells cease to be distinguishable: close to the
periphery, and corresponding with the external striæ which I have described (p. 246), a
circle of about fifty very conspicuous ducts is observed, each duct having a diameter
three times” that of the reticulated cells: they are separated from each other by one or
two rows of the same kind of cells that fill the main area, the circumference of the nucleus
being formed of a very thin epidermis lined with parenchyma. On examining another
slice of the same seed, cut in a vertical direction parallel with the axis, a somewhat
different appearance is manifested; the cells no longer seem reticulated, but form regular
longitudinal channels, interrupted by transverse septa placed at distances nearly equal to
their diameter, bearing the semblance of articulated tubes or muriform tissue ; they cease

the seed, and to determine whether we are right in considering it to be an arillus, as
doubts have been suggested on this subject by some eminent botanists. In the Clusiee,
this consists of an entire coating, without the smallest fissure; it is fleshy, equal in sub-
stance, not very thick, and generally of a reddish or orange colour. In the Tovomitee
(at least I speak from observation in Tovomita and Commirhaa, and Póppig relates the
same of Chrysochlamys), it is slit upon the dorsal face from top to bottom, with its fim-
briated edges overlapping each other, so that when opened out, it appears like a flat sheet
with the seed attached in its centre. In the Garciniee, the external coating is much
thicker, of a more fluid and mucilaginous substance, generally edible, and quite entire, as
in the Clusiee. Notwithstanding the different aspect and texture of this covering in the
two last-mentioned tribes, its nature cannot there be questioned, and it is quite fair to
conclude that the precisely analogous development in the C/usiec is, in like manner, a
true arillus. It is, however, essential to determine this point beyond cavil, because in the
Hypericine, Marcgraaviacee, and other orders, it has been held to be merely a thickened
epidermis of the testa, while in the Magnoliacee it has been assumed to be the testa
itself. In the latter family, where the seeds are generally suspended by long funicular
threads, it forms a very conspicuous development, under the appearance of an entire,
fleshy, scarlet-coloured covering, precisely similar to that of the Olusie@, and where in
like manner within it, on one side, somewhat pressed into its soft substance, is seen pro-
ceeding from the basal hilum to the apex a flattened raphe, the upper extremity of which
is lost in a fungous spot filling the cavity of a distinct aperture pierced through the
osseous shell,—a tunic which by most botanists has been regarded as the testa, but which,
by some authorities, has been held to be the inner integument of the seed, called tegmen
by Mirbel, and endopleura by DeCandolle. Endlicher was the first to suggest this idea,
which he expresses in a very ambiguous manner; in his ‘Genera Plantarum,’ p. 837, he
states that the seeds of the Magnoliacee have, in most cases, an external, fleshy, coloured
integument covering a crustaceous festa, with its raphe situated between it and the testa, `
and terminated by a chalaza in its summit, but that sometimes there is no outer integu-
ment, the raphe in such case being found between the ¢esta and endopleura. In this
definition, Endlicher evidently designates by the term chalaza, the aperture in the sum-
mit of thé Zesta, which I have called diapyle, and such misapplication of the term chalaza
(a word, strictly speaking, confined to the peculiar thickening of the tegmen or inner
integument, where it is connected with the raphe around the point in which all further
trace of the continuity of the nourishing vessels ceases) has probably led to the error of
considering the true festa to be the tegmen of the seed. In the diagnoses of the several
genera of the Order (at least in the tribe Magnoliee), the first-mentioned character is
assigned in detail to each genus in succession; but as the latter very inexact feature
(where the raphe is found between the testa and inner integument) is applied to no single
genus, it was probably meant to refer to the Z//iciec*, although this is nowhere explained
or described. Dr. Asa Gray, however (in his ‘Genera Pl. Un. St.’ i. p. 60. pl. 23), adopts
_ and amplifies this suggestion in unequivocal terms; stating that in Magnolia the seed is

exarillate, and he denominates the scarlet-coloured external tunic the testa, which pre-
ceding botanists have considered to be the arillus, while the hard erustaceous shell, called
testa even by Endlicher, is designated by him as the tegmen. This he infers from the
fact of having observed spiral vessels in the placentary attachment of the ovule (loe. eit.
fig. 7), which he thinks “ clearly demonstrates that the baccate exterior integument of
the seed is formed of the primine ‘of the ovule, and therefore is not an arillus*.” Had
this distinguished botanist actually traced the growth of this last-mentioned tunic in its
different stages, from the primine of the ovule, he would have established an inexplicable
fact, but this he does not appear to have done; simply therefore because the primine is the
more exterior tunic of the ovule, and the arillus is the outermost coating of the seed, it
does not necessarily follow that the one is the product of the other; and notwithstanding
the argument of Dr. Gray, there is little reason to doubt that in Magnolia the scarlet
envelope is due to a subsequent growth over the primine, as occurs in other numerous
well-known cases. I would not, however, now presume to question the validity of an
inference standing upon such high authority as that of my valued friend, without being
able to offer reasons grounded upon observations made by me many years ago in Brazil,
upon living seeds of Talawma, a genus closely allied to Magnolia. 1st. I found the thick
outer tunic to consist of a fleshy or oily matter in distinct granules enclosed within a thin
external epidermis, and an inner one of a similar nature; this is the usual texture of
arillus, not of testa. 2nd. The coating called tegmen by Dr. Gray, and considered by him -
as the innermost integument, is in reality the intermediate envelope in Talauma ; it is
black in the living state, with a small basal hilum; a longitudinal furrow runs along its
ventral face for the reception of the raphe, and a brown fungous scar, through which the
raphe finds a passage to the interior, fills a hollow cup in the apex, where there exists a
distinct aperture (the diapyle) for this purpose: this process Dr. Gray, following the
example of Endlicher, considers to be the chalaza: the crustaceous envelope is thick and
osseous in texture, bearing all the characters of a testa, and certainly none of those of an
innermost integument of the seed. 3rd. The existence of a membranaceous inner integu-
ment around the albumen, first indicated by Gærtner, within the true testa, thickened
and discoloured around its summit by a well-marked chalaza, where it is attached by a
short neck to the fungous process that covers the diapyle, and where it unites with the

* St. Hilaire has expressed similar views in regard to Euphorbiacee (Leçons de Bot. P. 728), — his notion
upon the authority of Schleiden, who, although a very acute observer and a physiological botanist of the highest
repute, is not always free from error in his conclusions, and who asserts that the external fleshy coating of the seed of
Euphorbia is derived from the primine. I have examined a great many seeds of afboreadent Fnphorbserse in Brazil,
and have found them generally covered with a coloured fleshy arillus, having a distinct raphe extending from the
apical hilum to the basal diapyle of the bony testa, and which cord constantly oceurs porno the testa and ailes :
there always exists a more internal membranaceous integument with its basal chalaza. It is therefore clear in these
cases, as in the instances alluded to in the text, that the nourishing vessels proceeding from the placenta through the
funiculus to the foot of the primine, will, by the reversion of the ovule, necessarily have become extended vith m cag

| raphe, is a development wholly unnoticed by Dr. Gray, by Endlicher, or by DeCandolle ;
but it is an important feature, because it proves that the bony coating is the testa, and
not the tegmen as has been inferred. 4th. The raphe proceeding from the hilum is wholly
exterior to and free from the osseous coating, and interior to the outer tunic ; and this is
the constant position of raphe, when it is free, in regard to arillus and ¢esta,—assuredly
not in respect to testa and tegmen. 5th. As the raphe consists of the nourishing vessels
originally existing in the funiculus or placentary attachment of the anatropal ovule, it
could never have existed between the primine and secundine, but must have been, as Dr.
Gray figures it, wholly exterior to the primine, and consequently, as we afterwards find
it, outside the testa, which is the product of the primine; hence as the raphe is found in
a free state, though partially impressed in its soft substance, within the external tunic,
the inference is irresistible, that the latter must be of posterior growth, therefore arillus,
and in this manner enclosing the raphe. 6th. We have thus the evidence complete, of
the existence of the usual and distinct envelopes around the nucleus of the seed, viz. :—
an inner integument with its apical chalaza, an intermediate hard testa with its corre-
sponding diapyle, through which the nourishing vessels of the more exterior raphe pene-
trate, and the whole included within a scarlet-coloured soft arillus.

From all these facts we may safely infer, that the envelope, which is unquestionably an
arillus in the Garciniee and the Tovomitee, must be of the same nature in the Clusiee,
and that which is arillus in the Olusiee must be the same development in the Magno- .
liaceæ : that which is granted in the one cannot be denied in the other. Although it be
true that the several envelopes of the seed in different families are not to be recognized
alone by their consistency, which may be, contrary to general rule, more or less membra-
naceous, ligneous, cellular, or composed of oily or resinous granules according to circum-
stances, yet they may be determined by their. relative position in regard to raphe, chalaza,
diapyle, micropyle, hilum, &c., from which their true nature may always be inferred with
greater certainty*.

* The want of precaution in attending to the nature of the nourishing vessels proceeding from the placenta and
penetrating the different integuments, in order to promote the growth and perfection of the seed, has frequently led
to a misconception of its real structure. These vessels present themselves in the shape of a raphe-like cord under
three very different aspects :—1st. When the cord, originating in the base of the cell, terminates often at the opposite
extremity in the hilum of the contained seed; it is then properly the funicular cord, of which the common Cherry
affords a very good example: sometimes it is inappreciably short ; in other cases, as in Magnolia, it forms a very long
thread, by which the seed is suspended when it escapes from its cell. 2nd. When these vessels, existing in the form
of a thread, either free and exterior to the testa, or partially imbedded in its substance, spring from the point of attach-
ment of the hilum of the testa, and extending along its surface, penetrate its substance at a spot called the diapyle, to
unite with the chalaza of the inner integument, which is invariably opposite to the cotyledonary end of the embryo ;
this is the well-known raphe. 3rd. When the vessels passing from the hilum penetrate the inner integument and
extend in the shape of a thread beneath its surface, in order to attain the radicular (not the cotyledonary ) extremity
of the embryo; in this case they constitute the suspensor, which has sometimes been mistaken for a raphe; it
occurs in Tropeolum, where its origin has been well illustrated and described by Dr. Giraud, in a memoir on the deve-
lopment of the embryo in that genus, published in the nineteenth volume of the Society’s Transactions. The want of
attention to the existence and position of the true raphe has often led to erroneous inferences in regard to the affinities
of different genera, and among the Clusiacee may be cited the instance of Calophyllum. Gærtner (De Fruet. i. 200.
tab. 43. fig. 1) gives an analysis of its fruit, where overlooking the existence of the raphe, he has mistaken the extra-

. AND PECULIAR FORM OF THE EMBRYO IN THE CLUSIACEA. 255

. Connected with the issue of this question is that of the origin and mode of growth of
the arilliform covering of seeds, which by St. Hilaire is considered to be of two kinds;
one designated by him the {rue arillus, the other the false arillus; the former he defines
as an envelope open at its extremity, while the latter entirely covers the seed*. This has
been well discussed by Dr. Planchon; in an able memoir on the subjectt, where he greatly
modifies the views of St. Hilaire, and proposes to give to the false arillus the name of
arillode. Under this point of view, both kinds of envelope are alike in colour, texture
and form, being either gland-like, lobed, laciniated, more or less cupuliform, or entire and
wholly concealing the testa; their difference consisting in this, that the arillus, whether
abbreviated or entire, always covers the micropyle of the testa, while the arillode con-
stantly exhibits a minute or larger opening in its surface, around the micropyle, which is
never covered by it (loc. cit. p. 10), and he further points out the mode of distinguishing
the one from the other. “Si cette ouverture (le micropyle) est cachée par l'enveloppe, ou
si elle doit l'étre, dans le cas où celle-ci serait prolongée, on a un véritable arille. Si le
micropyle, au contraire, n'est pas recouvert par l'enveloppe, ou ne peut l'étre méme par
cette dernière prolongée, nous aurons un faux arille du méme genre que celui de |’ Euo-
nymus." It will be seen that St. Hilaire points to Euonymus as an instance of his true
arillus: Dr. Planchon, on the contrary, selects that genus as offering the type of his
arillode. He traces the distinction that exists between them from their different sources
of origin, attributing the growth of the true arillus over the ovule to a gradual enlarge-
ment of the funiculus, and noticing its earliest appearance from a mere swelling of the
umbilical cord to its gradual increment and ultimate development; but the arillode he
states to be derived from an enlargement of the mouth of the exostome or foramen of the
ovule, its margin being reflected and produced over the primine, thus growing upon it in
the form of an additional tunie. In either case, whether this accessory coating be of the
nature of arillus or arillode, it is clear, if it be entire, that the raphe must necessarily be
enclosed within it. The arillus, according to this view, is found in the Passifloracee,
Dilleniacee, Anonacee, Samydacee, Turneracee, Bixacee, Sapindacee, &e., while the
arillode is conspicuous in Celastraceæ, Cactacee, Malvacee, Büttneriacee, Euphorbiacee,
&e.: in this latter family, however, the peculiar carunculoid swelling around the micro-
pyle (I do not allude to the fungous strophiole) is called arillode, while that integument
which I take to be the true arillus in that Order (note, p. 253) is considered by Dr. Planchon
to be a mere epidermis of the testa. It would indeed be difficult to discriminate between
a thin arillus and a thick epidermis, as both appear to be of the same nature, differing
only in their relative thickness. ‘The origin of the arillus is now well established, but

256 MR. MIERS ON THE STRUCTURE OF THE SEED

that of the arillode, as indicated by the interesting researches of Dr. Planchon, requires
to be confirmed by a series of more extensive and careful observations, before it be admitted
as a settled fact. The most instructive and conclusive evidence of the origin and subse-
quent extraneous growth of the arillus over the ovule, has been adduced by Cambessèdes* ;
he found among the ripe seeds of Casearia grandiflora many that were incomplete; and -
here, although the anatropal ovule showed itself in a state of complete abortion, the
arillus had grown over it to its full state of development, proving that where the ovule
had ceased to grow, the increment of the funiculus was not stopped in its progress of
extraneous production. - |

Among the instances cited and figured by Dr. Planchon of the development of the
arillode, is that of Olusia flava, where he describes its ovules as presenting two short
cupulary membranaceous appendages, one covering the fourth part of the ovule, the other -
much shorter and superimposed ; and while he inquires, whether one of these cups be due
to an expansion of the funiculus, and the other of the exostome, he seems inclined to
infer that both proceed from an enlargement of the foramen of the ovule. Such an
inference is opposed to the facts described in the foregoing pages, but his observation is
worthy of attention, although it is more probable that the appearances he describes are
those of a true arillus in progress of its development, the exterior swelling being perhaps
that enlargement which I have described as the stipitate foot of the arillus. According
to the views of Dr. Planchon, the exterior coating existing in the seeds of the Clusiee
must be a true arillus, because the micropyle, which I have mentioned as existing near
the hilum of the testa, is wholly covered by that envelope. It is proper to notice that
Cambessédes distinctly asserts that the seed of Clusia Criuva is enveloped in its apex by a
scarlet cupuliform arillus, in the work last referred to (p. 317. pl. 65. fig. 8), where it is
figured upon the extremity of the seed contrary to that of the hilum, and connected with
it by a raphe: this assuredly must be an error, made perhaps in transcribing the notes of
St. Hilaire, who by such swelling probably intended to figure the cupuliform caruncular
process surrounding the diapyle, which I have shown to exist in the same position in the |
summit of the testa: that such a mistake evidently exists, is proved by the circumstance
of Cambessédes having described and figured the arillus in the apex of the seed, instead
of being at the dase, as it would have been had it been in existence. Von Martius (Nov.
Gen. et Sp.. iii. 166) describes the ovarium of Quapoya (Schweiggera) as containing
“ovula basi arillo vaginata,” and Endlicher, upon no other authority than the above,
states that the seeds of Havetia are “basi arillo subcarnoso lax? cupulæformi cincta,”
and he assumes upon no better evidence the same in regard to those of Quapoya, which
in that genus Aublet affirms to be “ pulpa rubra involuta.” y

The facts which I have here brought together, relative to the structure of the seeds in
this family, must in a considerable degree change our views of the affinities of the Clu-
siapec. They serve to bring the Order into close proximity with the Rhizobolacee, a
relationship founded upon analogies in the floral structure, long ago pointed out by Cam-
bessèdes +, but now rendered still more evident by the great similarity observed in their

extraordinary embryonal development. In this last-mentioned family, the embryo of its
exalbuminous seed exhibits, in like manner, a gigantic radicle furnished with exceedingly
minute cotyledons; with this difference, however, that the cotyledons here are separated
from the great body of the radicle by a slender free neorhiza or neck ; but if we imagine
the suppression of this neorhizal extension in the Rhizobolacee, and the close approxima-
tion of its minute cotyledons to its monstrous radicular mass, there would be little or no
difference in the form of the embryo in the two families. At the same time that these
circumstances tend to draw closer the affinities of the Clusiacee to the Hypericaceæ and
Marcgraaviaceæ, they remove them to a considerable distance from the Ternstræmiaceæ,
with which Order they have been hitherto considered to be most intimately related. At
present, I will do no more than indicate these considerations, as it is my intention to discuss
this question more extensively upon a future occasion, when I treat on the general
organography, floral structure, and generic features of the whole Order, restricted as I
propose it to be. I will merely observe, that in the course of this investigation, I have
met with many singular deviations from usual forms, and numerous interesting facts
well deserving of record.

XXIX. Evtract from a Memoir on the Origin and Development of Vessels in Mongéc-
— tyledonous and Dicotyledonous Plants. By Dr. FRANCISCO Frere ALLEWÉO, of
Rio de Janeiro. Translated and communicated by Joux Miers, Esq., F.R.S.,
F.L.S. $c. | |
Read January 16th, 1855.

In 1849 ı began a series of microscopical investigations upon several points of vegetable
anatomy, among which was one that attracted my chief attention, because of its greater
novelty,—the origin and development of vessels in the roots of plants.

In 1851, I read before the Vellozian Society of Rio de Janeiro a short memoir, in
which the most important facts that I had observed were collected, and which appeared
to me wholly new to science; at least I have found no record of them in the books
within my reach. That memoir, being accompanied by drawings, could not then be
printed, but I afterwards revised it, made it somewhat shorter, added other remarks, and
suppressed the drawings: in this form it was published in the following year (1852), as
the “Third Memoir of my Botanical Exercises :” (Trabalhos da Sociedade Velloziana,
BAUER. v 7

In the year 1853 I continued the same pursuit, when my attention was not limited
to the examination of the growth of vessels in germinating seeds, but was directed also
to that of dicotyledonous plants considerably advanced towards a ligneous state: similar
observations, extended at the same time to the growth of monocotyledonous plants,
convinced me that their mode of development was exactly the same as in Dicotyledons.

This last investigation is not yet completed; it will be of considerable length and
accompanied by explanatory drawings, so that I know not when it will be finished : but I
send you now an extract from it, with such details as may be requisite to make the
drawings that accompany this understood: I am the more anrious to do this, in order to
learn whether my observations are new, and worthy of the attention of European botanists,

or whether they are already known or sufficiently exact.

Fig. 3 is the same plant, still more grown, of its natural size. !

Fig. 4 is the same, much magnified, as seen by the microscope. The cotyledons now
exhibit their nervures, consisting of tracheæ considerably increased ; the gemmule, c, is
now observed under the form of a cellular tumour without vessels; the four trachex in
the stem descend in a parallel direction as far as the radicular bulb or bourgeon, b, con-
stituting thus the medullary sheath : rootlets are not yet observable.

Fig. 5 represents of its natural size the same plant now having roots, one of the leaves
of the gemmule being at the same time fully developed. :

Fig. 6 is the same, magnified and divided longitudinally, as seen by the microscope.
The cotyledons remain as in the preceding case, with the exception of their having now
acquired more nervures : the primordial leaf, f, is also seen with nervures consisting of
tracheæ only, of which two, constituting the midrib, descend by the stem to meet the four
cotyledonary tracheæ : in the stem or primary merithal* (radicle of authors), those
tracheæ, a, are as yet solitary for two-thirds of the upper portion of their length, but in
the lower third they are accompanied and invested externally by dotted vessels, b: at.
the point d, the limit between the stem and the root, the tracheæ of the stem terminate,
and we see the commencement of the dotted or ligneous vessels, which begin to ascend in -
bundles through the stem outside the tracheæ, and descend through the roots without
being accompanied by tracheæ: e is a more magnified figure of half the former vertical
section of the mesophyte at the vital point, where at e' is shown the termination of the
tracheæ of the stem, and where the dotted vessels are seen ascending through the stem
and descending through the main or perpendicular root e", and also through a ramifica-
tion of the root at e".

From this investigation we may infer the following results :— `

1. The tracheæ, which are the first vessels formed, derive their origin in the stem at
the vital point or horizontal plane in which the leaves originate, whence they extend,
forming bundles, upwards in the leaves to constitute the nervures, which extending down-
wards through the stem form the medullary sheath. |

2. Roots do not exist in the embryos, but are formed in the young plant, when, freed
from its seminal envelopes, it penetrates the earth: (there are exceptions to this rule in
some embryos, where, from a delay in the rupture of the integuments, the roots begin to
sprout while in the seed.) But there exists in such case the root-bud (** gommo ”) or
`. radicular bulb, which is destined to produce it, and which bears some analogy to the

gemmule, and may be considered as a primary spongiole, because by its means the plant
absorbs nourishment before it has roots.

T According to the doctrine of Gaudich aud (Recherches Générales sur l'Organographie, &c. p. 5), every germinating
point or elementary leaf in a plant has its superior and inferior vascular system, the superior or ascending being
resolvable into three parts or ** merithalles,” viz. the caulicular (tigellaire), the petiolar, and thé laminar (limbaire),
or better designated as the superior, middle, and lower merithals, the line of separation between the two former being
called by him the * mesophyte,” that between the two latter the « mesophylle :” the inferior or radicular descending
system is separated from the lower merithal by a point which he calls the * mesocauléorhize," which is the primary

vital knot (“nœud vital ”) of the stem, constituting its real base, and the true summit of the root.—(Note of the
TRANSLATOR.) , l

VESSELS IN MONOCOTYLEDONOUS AND DICOTYLEDONOUS PLANTS. 261

3. The fibrous, ligneous or retieulated vessels are of a formation posterior to the
appearance of the tracheæ, their origin being at the vital point or horizontal plane from
which the roots proceed, and whence they extend in bundles upwards through the stem,
till they reach the extremity of the nervures of the leaves, being always exterior to the
tracheæ, and downwards through the root till they attain its extremities, leaving almost
always in the centre a kind of canal filled with cellular tissue, which is true pith, and
which extends itself laterally, communicating with the herbaceous envelope by means of
medullary rays: but this pith is not enclosed by tracheæ in dicotyledonous plants; they
exist, on the contrary, in the roots of nearly all monocotyledonous plants, where, when true
tracheæ do not exist, their place is supplied by mixed or scalariform vessels. I have here
carried my deductions beyond the points shown in the drawings, which are now pur-
posely curtailed ; but I have made this digression in order to explain my views: with the
same object several well-known facts have been repeated: all that appears here. really
novel is the extension of two vascular systems, in opposite directions to each other, and
their increment at their respective extremities, by which is meant the propagation upward
and downward of fibres or vascular bundles.

4. Finally, the radicular branches, as appendicular or radiated organs (fig. 6, e, e"),
are in their origin perpendicular to the cauline fibres, and without continuity with them.
This is contrary to the theory maintained by M. Gaudichaud.

Drawing B.—This exhibits the microscopical observations made upon a young rooting
bulb of Fourcroya gigantea, which tend to prove the facts before affirmed.
Fig. 1: young bulb, of its natural size.

Fig. 2 shows the plane of a longitudinal section passing through the centre of the bulb.
Here, in the midst of an apparent confusion of vascular bundles, I obtained the result
shown in this figure only after numerous and patient dissections, but the result was
repeated frequently. The bulbous mass is formed of rather dense cellular tissue full of a
viscous lymph, the cells of which contain much fecula, i, and a large quantity of raphides,
ï, or solitary prisms, i". It gives origin upwards to many sheathing and concentric leaves.
Of these the central one, a, which is commencing its earliest development, is ‘composed
only of very slender cellular tissue: the one next in succession, exteriorly, is still cellular,
but beginning to receive tracheal ramifications, which are the upper extremities of
. numerous simple tracheæ, formed like a crown about the vital point, ot horizontal plane,
which I have supposed to be the limit between the stem and the leaves, although it is
difficult to determine its exact placé, as each leaf has its distinct plane, the intervals
being true merithalli. These small tracheæ, b, are exceedingly slender and of a vermi-
cular or fusiform aspect; they form a seat or curvature in the middle, the convexities of
which look toward the centre; thence they extend upwards, penetrating the leaves in
great number, parallel to one another, and are prolonged downwards, igni and
placing themselves outside the interior bundles, having a flexuose direction, as ives in
c,d,e. In the succeeding leaves there are no simple tracheæ, but numerous rachew
form bundles or cords, which penetrate in great numbers parallel to one another in each

leaf, till they reach the extremity, taking ulteriorly lateral and "ma

anastomosing in a very beautiful manner: these vascular bundles or cords also, in their
descent, reach the base of the bulb. Now, if we take one of these bundles and examine
it in its whole length, viz. the bundle c, d, e, it will be seen that in c and d it is formed
only of tracheæ, and that in e, besides tracheæ, it has dotted vessels on the outer side
which extend upwards till they penetrate the leaves, /, and downwards they are in com-
munication with the root: at f is seen a crossing of tracheal bundles, which indicates
that the primitive bundles, instead of divaricating from each other, cross in the centre,
although I confess that such crossing may not be real, but apparent, and owing to error in
observation, notwithstanding that I have seen it more than once: g shows a portion of
two roots whose vascular system is formed of a certain number of bundles, disposed in a
parallel direction with admirable symmetry, among which are seen dotted and scalariform
vessels, À : no true tracheæ are observable here.

We have in this case proved the same results which are noticed among Dicotyledons: a
great number of microscopical observations, made upon various plants under different
circumstances, have confirmed these views, which I consider to be unquestionable.

FRANCISCO FREIRE ALLEMAO.
Rio de Janeiro, December 11, 1853.

Notes by the TRANSLATOR.

The foregoing microscopical observations of Dr. Allemäo, which seem to have been
carefully made, are deserving of attention, inasmuch as they offer confirmatory testimony
of the truth of certain physiological facts which stand upon record. I am enabled by
the knowledge of his antecedent researches, published in the Proceedings of the Vellozian
Society, to explain his object in making the above communication: he was desirous of
testing the validity of the theory first suggested by Du Petit Thouars, and more recently
modified and supported by Gaudichaud, which contends, contrary to the views of Mirbel
and other eminent physiological botanists, that all woody fibres of the stem proceed from
the nascent leaf-buds and thence descend to the radicular extremity of plants. Dr. Alle- -
mão states (loc. ci. Exerc. Bot. p. 104) that his observations in no way tend to support
this theory. The facts, he observes, are best demonstrated in the stem of Cucurbita
Pepo, where the dotted vessels are extremely large and conspicuous: here no reticulated :
vessels are found in the ultimate leaves, or even in the last and its nearer internodes -
(merithalli), although they are found in the lower and older leaves: he observed spiral
vessels only in the stems or leaves, as low as the ninth or tenth axil from the extremity
of each branchlet ; from that point, as low as the fourteenth and fifteenth axil, other
vessels are observed in the stem only ; but below this point he found them in the stem,
and more especially in the leaves, proving that all reticulated and dotted vessels ascend
through the stem, before they find their way into the leaves, in their progress of growth
upwards. On the other hand, we have evidence long ago established, which may be said
to be the touchstone of the various theories that have been advanced on this subject ;—the
fact of the formation of a circular tumour in the trunk of dicotyledonary plants, above
the line of a ligature tightly tied around it. This intumescence is undoubtedly produced

VESSELS IN MONOCOTYLEDONOUS AND DICOTYLEDONOUS PLANTS. 263

by the depositions left by the descending sap from the woody fibres, where its progress is
thus stopped. Hence the question arises, how is it that fibres ascending from the collar
of the root create this deposit above, and not below the impediment ? Dr. Allemäo thinks
this may be accounted for by reasoning on the facts established in the preceding memoir,
viz. that in the development of the vascular fibres observed in the stem, there always
exists a vital centre, whence they extend themselves in two opposite directions. Now
this vital centre*, or central point in the formation of fibre, may be fixed, moveable, or
‚accidental: fixed in woody fibres, moveable in tracheæ, and accidental in all adventitious
formations. If, for instance, we take a cutting of any young branchlet in which no
natural bud is distinguishable, and plant half of it in the ground, several vital points
that may be considered adventitious make their appearance, the lowermost of which will
` give out rootlets, and the uppermost leaf-buds. Is it not therefore clear, asks Dr. Allemäo,
that in the “vital zone” of this cutting, vital points or centres appear, which would never
have existed in the natural condition of the branch ? Applying this fact to the case of
the ligature before mentioned, it is evident that the cambium or elaborated sap, or what- -
ever be the source of the tumour deposited between the wood and the bark, must assuredly
proceed from the leaves toward the root, and meeting with this obstacle, becomes accu-
mulated there: its tendency to organize itself not being distributed, a zone of adventi-
tious or occasional vital centres appears in that point, whose two forces are soon mani-
fested ; the ascending fibres continue to extend themselves without impediment, while
those which should have descended, unable to overcome the impediment presented to
their further progress, continue to grow, twisting and interlacing themselves sa as to
form a tumour. Under this point of view, Dr. Allemäo concludes that his principle of a
. vital centre is established.
- I cannot perceive any essential difference in these conclusions from the views of Gaudi-
chaud, who contends that all the various organs of plants spring from the development
of buds generated around the central medullary sheath of the stem, producing by their
extension beyond the surface of the stem, leaf-buds, out of which proceed leaves, scales,
calyces, corollas, stamens, carpels, ovules, cotyledons, &e., which are each only creme À
modifications of one original vegetation—the phyton. These buds exist either in an
active or a passive state, and being in the latter case only rudimentary, they often: remain
in the embryo-state of an organized cell, which may at any time under cem circumstances
become active. He shows that each active bud has a development of its own, expanding
in two opposite directions ; upwards to form fresh leaves, inflorescence, &e., and ed
principally spiral vessels; and downwards by means of dotted or scalariform ura s
towards the roots, producing in their progress depositions of woody fibre, which annually
increase the diameter of the stems. Dr. Allemão’s general remarks tend to confirm these

* This same term, “ nœud vital,” was, I believe, first used in 1830 by Turpin (Mém. Mus. -— 16) to irata
the latent bud, whether existing in the stem, in suckers, or in underground tubers, each “nœud vn rs a =

He showed that the tubers of the Potato and Topinambour are true subterranean stems, furnished wit sr

of which is simply an expanded root.—J. M.

facts, although in the preceding communication his observations relate only to the deve-
. lopment of the primary bud of an individual plant, that is to say, of the growing embryo
of a seed. He observes (Joc. cit. p. 105) that Mirbel in one of his latest essays on this
subject (Acad. Se: Paris, June 1843), in opposing the views of Gaudichaud, demonstrates
the fact that the circulating vessels ascend from the point of their origin in the stem, and
thence extend to the leaves, but that he does not here distinguish the difference between
tracheal and dotted vessels ; while, on the other hand, Gaudichaud comprehends in his
descending system the same vessels, both vascular and fibrous: his own observations,.
however, conform only with the theory of Gaudichaud inasfar as regards the propagation
downwards of tracheal vessels, and with the latest views of Mirbel relative to the propa-
gation upwards of dotted or fibrous vessels; and they are opposed to both, in respect
to the evolution of each fibre upwards and downwards in opposite directions*. There :
appears to me here a misprint, or complete misapprehension of the views of Gaudichaud,
who clearly traces the source of each bud, not from the point of external growth, as Dr.
Allemäo seems to infer, but; as I have above remarked, from the seat of its origin around
the medullary sheath, at the “næud vital,” or point of departure of each independent
ascending and descending system of vascular fibre. The origin of numerous distinct bud- `
formations around the medullary sheath, and the extension of ascending spiral vessels
and of corresponding descending dotted vessels from each of these separately, are main-
tained throughout by Gaudichaud in his * Rechérches Générales’ as an essential part of his
theory; and these are minutely demonstrated in pl. 7. fig. 41, 42, 44, pl. 8. fig. 4, 5,6; &c.,
in dicotyledonous plants, and in pl. 9. fig. 1, 2, 3, 4, and pl. 10, in monocotyledonous plants. -
In support of his theory he also gives numerous other illustrations, even foreibly quoting
the same circumstances of the intumescence of a stem produced by a ligature, and the
germination of an apparently budless stem, both which facts Dr. Allemäo considers to
strengthen his own views in opposition to those of Gaudichaud.

. A precisely analogous development to that delineated in the preceding memoir was
pointed out by Mirbel in 1809, showing the origin and formation of similar vessels in the
germinating seeds of Nelumbo (Ann. Mus. xiii. 471. pl. 34. fig. 19), where they are depicted
as originating from the neck of the plumule, and branching thence into the nervures of the
cotyledonary leaves, while others tend downwards into the growiug radicle: these several
vessels were first observed by Bonnet, and described by him as ** mammary vessels," as
far back as 1754. Mirbel described all these ascending vessels to be of spiral structure,
and the others tending to and through the roots, to be strangulated or dotted vessels,
which, though incapable of being unrolled, he considered to be only modifications of the
spiral form, an opinion which he afterwards somewhat modified. Long prior to this (in
1502), Mirbel read a memoir to the Institute, expounding these facts; and we find a very
concise account by Desfontaines, of these able researches, in the 5th volume of the * Annales
du Muséum’, p. 80, with two elaborate plates, showing the ascending system of spiral

vessels in the plumule and cotyledons, with the descending system of dotted vessels in the
radicle, as distinguished in the germinating embryo of the common French Bean.

Another fact related by Dr. Allemäo is, that although the “bolbo radicular” is always
the main growing point of the radicle, he observed in Luphorbiacee, four other cruciform
branches on one horizontal plane, proceeding from this radicle. This fact is not novel,
for it was noticed more than forty years ago by St. Hilaire (Ann. Mus. xix. 468), where
he describes the same feature in the germination of a Ranunculaceous plant (Cerato-
cephalus): here the main shoot is shown, growing in the ordinary way of an exorhizal
root, but four other branching rootlets are produced on one plane, from the collar of its
young root, which make their appearance through lacerations of the external tunic: their
earliest indieation is in the form of tubercles, through the investing covering of which
these rootlets burst a passage, in all respects like the coleorhiza observed in the germi-
nating embryos of monocotyledonous plants, so that, although the main root here is
: exorhizal, the secondary rootlets are distinctly coleorhizal. This coleorhiza is sometimes
extended to some distance, along with the rootlet; but in other cases it forms merely an
areola around its base. St. Hilaire observed the same appearance in the growing embryos
of numerous other exorhizal plants, as those of Plantago, Valerianella, Urtica, Senecio,
Sonchus, Calendula, Matricaria, Veronica, Phaseolus, Medicago, &e., although it is not
of general occurrénce. In the singular mode of germination of the seeds of Tropeolum,
the radicle, though exorhizal, exhibits a kind of valve-like opening for the exit of the
plumule, which has been called a coleorhiza: a somewhat similar appearance is said also
to occur in the germination of the seed of Viscum album, but that I apprehend can refer
only to the coleorhizal mode of bursting of the attenuated expansion of the thin covering
of the albumen which is spread over the growing radicle.

Dr. Allemäo here considers the radicle of the embryo as part of the caulicle or stem,
and the root as originating in the subsequent growth of the embryo, after it " released
from its integuments, and produced by the expansion of the obtuse extremity of the
radicle, which he calls the “ gommo,” and Gaudichaud the “ radicular bulb.” This view
was also taken by Turpin nearly twenty years ago, and is figured as such in the —5
tion of Solanum tuberosum, where all the radicular portion of the embryo is considered
as the tigelle, or part of the ascending system, while the true "e is shown Ww begin from
its sprouting point, called by Dr. Allemäo the “ bolbo radicular,” or“ gommo. This yy
though supported by some, has not been much countenanced, and I do not perceive the

advantage of this theory over that more generally received, which assigns to the radicle

the function of the elementary root, its commencement being at the point of union of the

cotyledons and their junction with the plumule. The contrary hypothesis is €
by numberless facts, and more especially by one to which I lately called the atten seas

the Linnean Society, the germination of the embryo of Xanthochymus, as SRM t
Roxburgh, where, in addition to the principal root thrown out at the base of the : a

the point which Dr. Allemáo would call the radicular bulb, another secondary root is
seen sprouting from the summit of the nucleus, out of the ascending collar or ee =
mediately below the scales which appear to be the minute cotyledons, showing that the

266 DR. ALLEMAO ON THE ORIGIN, ETC. OF VESSELS IN PLANTS.

main body of the nucleus or radicle belongs to the descending system of the root. It is
more natural to conclude, in the case cited by Dr. Allemäo, that the main descending
shoot growing out of the radicular bulb, and also the subsequent coleorhizal rootlets, are
productions of that axile portion of the radicle which I have called the “ neorhiza ;"
and under this point of view it is easy to account for the coleorhizal character of, the
secondary rootlets in the germination of Ceratocephalus described by St. Hilaire, which,
as a natural consequence of this structure, would assume that appearance. A very

singular example of this sort of production is shown by Klotzsch in the germination of

the seeds of Pistia*, where the many secondary rootlets or branches of the neorhiza force
their way through the epirhizal covering of the main root, extending it as a coleorhiza,
in the form of a long cylindrical tube, which at length breaks away, leaving a long sheath
in the form of a thimble covering the extremity of each growing rootlet, and which
probably thus performs the function of a spongiole.

XXX. Description of Peachia hastata, a new genus and species of the Class ZOOPHYTA ;
with observations on the Family Actiniade. By Puıuıp Henry Gosse, Esq., A.L.S.

Read March 20, 1855.

IN the month of J anuary 1854, and afterwards in March of the same year, the Rev.
Charles Kingsley found, in the vicinity of Torquay, many specimens of an Actinia, which
he kindly forwarded to me. As it appeared not only to be an undescribed species, but
to have characters which separate it generically from others, I venture to lay before the
Linnean Society my observations concerning it. i
- The body (Tab. XXVIII. fig. 1) is spindle-shaped or clavate, 4 inches in length, and

1 inch in greatest diameter, pellucid, very pale red, with numerous slender whitish lines,
running at equal distances down the whole length. These do not vary in width, and
are evidently the edges of the internal septa, seen through the translucent integument.
. The red colour is dependent on a thin epiderniis, which, as the animal is apt, when in a
sickly state, to distend itself greatly in parts, bursts, and separates into torn shreds, `
displaying the pellucid body beneath. |

The oval disk is very protrusile ; it is surrounded bya single circle of twelve (eleven in
one specimen) tentacles. "These are short, thick at the base, tapering to a point ; and
are frequently carried recurved over the margin, like rams’ horns (fig. 2). Their mark-
ings are peculiarly elegant. Each tentaculum is pellucid-white, as to its ground colour ;
but its upper side, or that which faces the disk, is variegated with arrow-heads of white
and brown, in two parallel lines (fig. 3). The arrows point towards the base of the
tentacle, and the colours are arranged alternately, one of white with one of brown fitting
into its angle, and so on: there are about six of white and six of brown in each of the
two rows; but towards the extremities they have a tendency to become confluent. i

The disk is somewhat similarly marked with arrows or vandykes ; but they point in the
opposite direction towards the circumference. The arrows of the outermost circle ve
strongly marked, and form a star or flower of twelve points, of deep brown ; of ones
points diverge again, to embrace partially the bases of the several tentacles. Wit s
circle there is a similar one of white, and within this, another of small brown arrows,
which are not united.

This curious apparatus appeared to form one side of the mouth,—to be, in fact, an
enlargement of the paries or lip, at one part of the eircumference, with nothing corre-
sponding to it on the opposite side. It was perforate, and, as I conjecture, led down to
the visceral cavity of the body, external to the stomach, constituting the orifice through
which the ova or young are ordinarily deposited. In the smallest specimen I could not
detect more than four or five of the cored papille on this prominence. Under a lens,
when the animal was sickening, and the lips were much protruded and everted, the organ
was evidently seen to be a tube, with thickened walls, enclosed within one paries of the
cesophagus, and with its margin studded with papilla. Into the orifice, which was
corrugated, I could thrust a bristle with ease. Fig. 5 represents the mouth in this
_ condition. | |

The natural habits of this Zoophyte, as seen in freedom, are thus graphically described
by Mr. Kingsley in his letters to me. ‘They lie (or rather stand) in wet, ribbed, clean
sand, at low-water mark, the disk just out of ground. On digging carefully (for the
animal retracts on the least shaking of the sand), you find that he is buried bolt-upright
to the depth of 9 inches, where his extremity stops; the whole animal tapering gradually
from stem to stern. On being taken out (no easy matter, since its power of retraction,
if irritated, is far more rapid and springy than in any of the class, as far as I have tried
them), and put into a vase of salt water, he swells himself out with water like a Holo-
thurian, disclosing longitudinal septa. He also has a tendency to transverse constric-
tion, like Scolanthus and Chirodota; but this has gone off in my specimens. All his
motions (at least before he has made a cold bath of his own skin by taking in water) are
rapid and spasmodic; betokening, as does his whole make, a higher muscular organiza-
tion than that of the Actinie.” |

None of the specimens made the slightest attempt to adhere; nor did the posterior
extremities show any appearance of a sucking disk. There was, however, a strong corru-
gation in that part, radiating from a central orifice, into which I thrust the point of a
pin without resistance to the depth of 4th of an inch.

All the three specimens which first came into my hands were more or less languid and
sickly when I received them. One of them was swollen into a balloon-like form, and
never expanded the tentacles at all. The others soon became invested with a thick
tenacious mucus, and though they retained the power of expanding and retracting the
tentacles, they burst the integument in one or more wounds, so that the convoluted bands
protruded. The latter organs were present in copious profusion, broad bands very much
frilled, with a slender “ beading” or thickened border, which the microscope showed to
be moderately filled with minute slender thread-capsules, about z4,th of an inch in
length, slightly curved; they discharged the thread freely, but with unusual slowness,
the lengthening of the tip resembling the progress of the minute-hand of a watch. One
that I measured, of an average length, extended to about th of an inch, or eighteen
times the length of the capsule. |

| as to conceal and envelope the body. As this protrusion proceeded, I found that these
bands were not the ovaries, as I at first supposed, but were attached to them. The ovaries
were protruded also in the form of thick tubes, much convoluted, and of a salmon-colour,
studded with minute white specks. These tubes were filled to distension with their
contents, and were consequently plump, at least at one edge; for, as well as I could
judge, they ran off at the opposite edge into a broad, exceedingly attenuated, gelatinous
ribbon. Along the thickened and tubular edge was attached the capsuliferous band, as a
mesentery; this also having a thickened margin, but differing in structure, as well as in
appearance from the former. It was narrower and much more eonvolved ; the edge lying
in pretty regular figure-of-8 turns, or scrolls, like the frill of a cap; the colour of this
band was dull yellowish, with the thiekened border white. This border was, as I have
said above, principally composed of thread-capsules; but in the salmon-red tubes I found
none of these organs. "They were filled with ova, enveloped in a red mucus, which gave
the colour not only to the tubes themselves, but also to the body of the animal. These `
ova were globose or pear-shaped bodies, very soft and elastic, the largest measuring „th
of an inch in length, by -45th in diameter; while others (of the globose form) probably
less advanced, were not more than z}sth of an inch in diameter. Indeed they rather re-
sembled the planules of a Plumularia or Antennularia than proper ova, except that they
had no motion, and were not ciliated. They consisted of a granular brown substance,
becoming clear and colourless at the circumference. T could see no trace of a nucleus in
any, either with or without pressure. |
The animals, so burst and apparently dead, I allowed to remain in a dish of pure sea-
water, with a growing leaf of Ulva, to preserve its vitality. To my surprise, they at
length were evidently everted, turned (by the continuance of the process of protrusion
through the ruptured integument) completely inside out, so that the membranous septa
of the interior now projected from the cireumference; while from each interseptal space
protruded the convoluted ovaries, with. their mesenteries and frilled bands. Nor did it
appear that death had really ensued. As an animal, an individual, I could not consider
it otherwise than deceased ; for it was become a shapeless mass of viscera, from which the
original integuments were sloughing, in films of glairy membrane. But no putrescence
had set in; and on examination with a lens, through the sides of a glass vase, to which I
had early removed the specimens, I found in each one, twelve days after they had been in
this dissolved state, that the ovaries maintained a perfectly clear, plump, -a
appearance (fig. 6), with a more vivid rose-tint than at first ; and that PGPT pu :
were slowly, but constantly, moving all over them ; puckering and olding vu

— a beautiful provision for the respiration, so to speak, of the yet undeve oped embryos,
by the perpetual passage of currents of the surrounding water along the ovaries.

little lovely Medusa, Turris neglecta,—by the protrusion of the scr er the RRR
and gradual dissolution of the umbrella, as I have elsewhere er rip nr i

the Pulmograde Medusæ, since I have observed it in several of the Covered-eyed genera.
The affinity between the Arachnoderm and Actinoderm classes of Raptata was already
known to be close; and these curious facts may add another link to the connexion.

If the rupture and inversion of the body in this instance was a normal process, it still
would not be inconsistent with the function which I assign (from analogy with other
Actiniade) to the curious papillated duct at the side of the mouth. Ova or living young
may be discharged through this orifice, at intervals, during life, and yet the most prolific
birth may be reserved for the period of the parent’s decease, when the whole contents of
the ovaries are committed to the waves. é

Whether it was so or not, however, I did not ascertain; for, about a week later, or
eighteen days after the evolution, I perceived that the mucous integuments were decom-
posing and becoming offensive. The ovaries and their bands wore nearly the same
appearance as before; but some of the former were dispersing in flocculent shreds, in
' which I could not detect any embryos more advanced than those which I had before
examined. The frilled bands maintained spontaneous motion, but very slow. I there-
fore took the specimen from the vase and examined it. I found it completely inverted ;
the tentacles were set around the interior of one extremity, and the papillated orifice at
the edge of the mouth was very distinctly seen. The papillæ are arranged around the
orifice in flat hand-like eminences, each containing three or four papillæ, resembling
fingers. The dark-brown cores, so well-defined that they look like solid bodies, under
pressure appear to consist of pigment-cells or granules, of similar consistence to that of
the surrounding flesh.

The anal extremity was much more distinct than before; the orifice being 3th of an
inch in diameter, and perfectly defined, with striæ radiating from its margin, and the
thickened septa commencing in a circle around it. Eten

No sac-like fundus was visible to the stomach, but it seemed to merge into the visceral
cavity, as described by M. Hollard (Ann. des Sci. Nat. 1851), and by Dr. Cobbold (Ann.

Nat. Hist. 1853); differing only in the fact just mentioned, that this cavity had a
posterior orifice. Ber | |

The possession of an excretory orifice to the body is a character of sufficient importance
to separate this species from the genus Actinia. I therefore propose to constitute a
genus for it, by the name of Peachia, as a tribute to the zeal, industry, and success with
which marine zoology has been studied by Mr. Charles W. Peach. I am influenced in
this selection of a name, also, by the circumstance that a species discovered by that
gentleman in Cornwall, and named by him Actinia chrysanthellum, appears to resemble
the present species closely, and may prove to belong to the same genus. It is very
minute, whereas this is a zoophyte of large dimensions; and the describer has not
mentioned the existence of a posterior orifice, nor of any papillated structure in front.
The former may, however, have been overlooked.

The genus and species may be thus characterized :—

The principal interest of this form is the decided approach which it makes to a higher
type of existence than that of the AcTINODERMATA. The sensitiveness to alarm, and the
spring-like rapidity of its motions, indicate a greater condensation in the nervous and
muscular systems; but the existence of a posterior opening to the digestive canal is a
still more decisive advance in structural rank. The approach to the ECHINODERMATA,
through the Sipwnculide, is marked, not only by this important character, but also by
form, by the degeneration of the tentacles in number and dimensions, and by the
' tendency to break up the body by spontaneous constriction.

"The genus Edwardsia of M. Quatrefages, still further diminishes the interval between
the Actinie and the Holothurie ; for the mouth and tentacula are, in that genus, seated
at the end of a delicate column, which is retractile within the coriaceous trunk, as it is
in Syring nudus; and the balloon-like inflation at the posterior extremity reminds us of
the same animal. It is curious to trace also, in Syrinz itself, an approach to the
Actinoderm-type, in the digestive canal terminating near the head, the greater portion of
the body being imperforate. x

I may observe, in passing, that the genus Ædwardsia is represented by two A
species. One was described and figured by myself in the ** Annals of Natural History for
Sept. 1853, under the name of Scolanthus callimorphus ; but, as I am now convinced that
notwithstanding the apparently simple posterior extremity in that species, it must be
referred to Edwardsia, the genus Scolanthus must be cancelled. The name will hence
become Edwardsia callimorpha. Another species is described by Mr. Kingsley (in litt.),
which appears to be E. Beautempsii of M. Quatrefages. ; :

I will embrace this opportunity of making a few observations on the more typical
Actinie. Restricted as is the genus Actinia, by the separation from it of Adamsia and
Anthea among British, of Metridium and Actinecta, and — others among exotic
species, and by the creation of such genera as Capnea, Corynactis, Ziyanthus, Ui dus

Applying these principles to the group before us, I find a number of Actinie, whic

have the well-marked character of projecting, from pores in the exterior of the body,
whenever they are irritated, thread-like filaments, in great abundance and to great length,
which are again withdrawn into the body. These filaments, when examined with a high
power, are seen to be chiefly composed of thread-capsules, or “ nettling-organs;” and I
have given elsewhere* evidence to show that their function is that of efficient weapons of
offence, paralysing even vertebrate animals, with which they are brought into contact.
Every one who has handled A. parasitica, venusta, or any of the species with missile
threads, is aware of the great tenacity with which these filaments adhere to the fingers,
This is owing to the penetration of the epidermis by the myriads of ejected threads, and
to the hold which their barbed structure enables them to retain. For when these nettling
organs are examined, say with a power of 500 diameters, the thread is perceived to be
armed in a manner which gives them a superiority over those of all the non-shooting
species; and thus the structure of these organs affords us another excellent and constant
generic character. There are, indeed, in these species, always to be found many threadi
capsules of the ordinary form and structure, viz. linear-oblong, emitting a thread which
is apparently simple, and of great length, extending to about twenty times the length of
the capsule. But the principal portion of the capsules are of another form, being long-
oval with a distinct longitudinal chamber, and emitting a thread, never exceeding thrice |
the length of the capsule, and more commonly one or one and a-half times, as in A. Bellis
(fig. 10), and in A. Troglodytes (fig. 11). The terminal portion of this thread (including
from half to more than three-fourths of its length, according to the species) is barbed
with close-set bristles radiating on all sides like the hairs of a bottle-brush, and more or `
less reverted. In A. venusta (fig. 7), a zigzag lineation is discernible on the thread,
which seems to indicate that the hairs are set on in a spiral arrangement. Before emis-
sion, the thread-chamber is very distinct in this species (fig. 8), running through the
whole length of the capsule, slightly bent in a sigmoid curve, and gradually merging into
the capsule-walls at the discharging end. In some instances the thread is discharged, in
every respect agreeing with that just described, but perfectly simple and without barbs
(fig. 9) : I think that this occurs when the emission has been very slow ; that the barbed
hairs fly out only when the missile force is sudden ; that, otherwise, they continue
appressed to the sides, and invisible. I can discover no trace of the spiral in the un-
emitted thread. . |
This brush-like form of the nettling-thread I find in ten of our native species of Actinia
(which I shall presently enumerate), invariably co-existent with the power of emitting
filaments spontaneously. They are marked also by other characters, of less importance
‚because less definite :—the tentacles are generally of small size, slender, numerous, and
much crowded ; the body is soft, rarely coriaceous, and smooth, though commonly per-
forated with sucking glands, which are distinct from the emitting pores; and the colours
of the body often have a tendency to run in longitudinal bands, and those of the tentacles
to form arrow-heads. The genus thus characterized I propose to call Sagartiat. |

such as I have had opportunities of personally examining) may be distributed into two
groups. The first contains such species as have the body studded with warts; the skin
coriaceous ; the tentacles moderately few, generally thick, conical, and obtuse, and for the
most part marked on their facial surface with transverse dashes of opaque colour. They
do not discharge filaments under any annoyance (when wounded, however, the convo-
luted ovarian bands protrude); and the nettling threads of their tissues are long and
simple, or at least never brush-like. That of A. crassicornis, indeed, is armed at its base,
as I have represented it elsewhere* ; but it is in a manner peculiar to itself, and totally
unlike that of the Sagartie. This fine species deviates, in some other subordinate parti-
culars, from the rest of the verrucose Actinie, and may possibly require ultimately to be
separated. For the present, however, I include it in this genus, which I propose to call
Bunodest. |

There now remains a group, for which, as it includes the most abundant of our species,
the everywhere-familiar Smooth Anemone (4. Mesembryanthemum), Y would retain the
appellation of Actinia. In addition to this well-known species we have two others on the
_ British shores, which I shall presently mention. Besides the negative characters which
mark these species—the absence of emitted filaments, and of surface-warts,—they have a
distinct positive one, in the existence of a series of spherical or oval bodies, of unknown
function, seated between the outermost row of tentacles and the margin of the disk. In
our native species these are conspicuous, from their opaque blue or white colour; but in
exotic species, they occut of other hues. In Mesembryanthemum, the ovarium-bands, and
the walls of the tentacles, are furnished with comparatively few thread-capsules, which
are linear, and very small; those of the bands being about 79th of an inch in length,
and those of the tentacle-walls not more than zy9th; whereas the ovate capsules of the
Sagartiæ run from glsth (Dianthus) to s}sth (parasitica); the length in most of the
species being about zjsth. d

The marginal spherules, however, are almost wholly composed of capsules, very nir,
and about z45th of an inch long. They very reluctantly emit the thread, which I have
therefore seen only in few instances. It is very subtile, and of considerable length ; but
I was not able in any case to trace it to its termination. From these facts I incline sis

unicolorous ; as is also the body generally, though this is sometimes varied by lines or
spots of another colour, which are by no means constant; a line of different hue more
commonly encircles the base. The tentacles are moderately numerous, of medium thick-
ness, tapering to a point.
These three genera may be therefore defined thus :— |
1. SAGARTIA, Gosse.— Actinie basi adhærentes ; tentaculis conicis, facile retractilibus ;
spherulis marginalibus nullis; corpus everrucosum, filamenta capsulifera e poris
emittens; filis urticantibus brevibus, pilorum fasciculo densè armatis. |

British species, viduata (=anguicoma, Price), Troglodytes, Aurora, candida, rosea,
nivea, venusta, parasitica, Bellis, Dianthus. Probably also aurantiaca and pulcherrima
of Professor Jordan. The following exotic species, figured by Dana in the Zoophytes of
the American Exploring Expedition, seem to be referable to this genus :— Primula, the
beautiful decorata, and Fuegensis, both allied to our Bellis; and Achates, reticulata, and
Paumotensis (perhaps the most magnificent of the whole tribe), which are evidently allied
to Dianthus. i

2. BUNODES, Gosse.—Actinie sphærulis marginalibus nullis. Corpus verrucosum; cute
coriaceá, filamentis missilibus nullis ; filis urticantibus longis simplicibus; tentaculis —
plerumque crassis, conicis, obtusis. :

British species, gemmacea, thallia, clavata, crassicornis, Monile (probably the young of
crassicornis) ?, Chrysoplenium?, alba?, miniata? Of exotic species, Diadema, pluvia,

Gemma, Artemisia, of Dana’s Zoophytes, probably come here.

3. ACTINIA, Linn.—Spherule capsulifere ad disci marginem seriatee. Corpus everruco-
sum, poris filamentisque missilibus destitutum ; cute levi. i

British species, Mesembryanthemum, margaritifera, Ohiococca. Exotic species, Tabella
and graminea of Dana.

The following British Species are of doubtful place ;—coccinea, intestinalis, biserialis,
vermicularis. The very curious biserialis of the late lamented Professor Forbes has a close
parallel in the Rhodora of Dana; and these may perhaps form another genus, when more
is known about them. Zntestinalis and vermicularis, both from the Shetland seas, show,
in their slender lengthened form, an approach to the free condition of Peachia, &c. The
latter of these is a deep-water species (eighty fathoms); and, as Professor Forbes
observes, looked when unattached “ more like a planarian worm than an Actinia.”

The following table exhibits one manner in which the British noncoralligenous
Actiniade may be artificially distributed:— — - iy

If we take Sagartia as the typical genus, which its superior populousness, and the
perfection of its armature entitle it to be considered, we may trace, as from a central
point, some of the relations of the Actiniade, inter se, as well as with other forms.

Adamsia comes very close to Sagartia, possessing the power of emitting filaments in
high perfection : probably the point of union between these genera will be S. parasitica ;
which, like Adamsia palliata, attaches itself to shells in which Paguri dwell; and which
is pre-eminent in its genus for the abundance and the tenacity of its filaments. The
passage from Sagartia to Bunodes is perhaps through S. Dianthus and B. clavata ;
the disk of the latter being very expansive, with the tentacles situated at its margin. ©
S. Bellis, in its power of assuming a saucer-like form for its thin expanded disk, to which
the narrow body serves as a foot-stalk, shows also a remote approach to Lucernaria, in
which this figure is permanent.

Lucernaria exhibits a beautiful link of connexion between the Actinoderm and the
Arachnoderm forms of RapıaTA. The Oceania turrita has its umbrella produced into a
long moveable spire, which looks exactly like a foot-stalk, by which it had been attached
when in a polype condition; while in Bougainvillea we get the numerous tentacula
gathered into groups. The mobile, four-lobed mouth of Zucernaria closely resembles
the peduncle of a Medusa. ; !

There is a curious analogy (I fear it is nothing more) between Zucernaria and the
genus Floscularia among the RoTIFERA : both are attached by a slender pedicel; both i
have a flower-like disk, jutting out into angles, which are beset with a multitude of fila-
ments (tentacles in the one case, setiform cilia in the other) that radiate in all directions.

The tender and soft-bodied little Sagartia candida and S. rosea seem to lead off ; to
Corynactis Allmanni, though the points of resemblance are rather general than special.
But this latter genus passes into Capnea, by a remarkable species described by Mr. W.
Thompson of Weymouth, in the Zoological Transactions for 1853, under the name of
Corynactis heterocera, and which I had an opportunity of examining while alive. Pro-
fessor Forbes has observed the close affinity of his Capnea sanguinea to the Zoanthade,
and the transition which the latter exhibit to the ereeping and budding Hydroid polypes
is sufficiently apparent. Corynactis, in its capitate tentacles, shows also a in Z
Cyathus Smithii, among the coralligenous ANTHOZOA d while the simply-oonical form o
these organs in Balanophyllia regia agrees with Aetinia, &e.

The transition from Sagartia to Actinia proper, I do not know how to trace, except:

The nearest alliance of Anthea is with Actinia ; to which, in the texture of its skin,
and the absence of warts, pores and, glands, it presents a close resemblance. The
received notion, that Anthea is incapable of entire retraction, I have elsewhere stated to be
incorrect ; and I have since had several opportunities of seeing it with the tentacles quite
concealed, and the animal assuming the ordinary butter-like shape of an Actinia. A
better character is the tendency which the tentacles have to form groups, like several
trunks of a tree united close to the ground. In this respect there is perhaps an approxi-
mation to Lucernaria; remote, however, for the clusters thus formed are still in con-
tiguity with each other; and the peculiarity cannot be discerned, except when the animal

is in the state of widest expansion. |

Finally, the species viduata appears to be the point at which the genus Sagartia leads
off towards the ECHINODERMATA. Though, in an Aquarium, it remains attached for
months together, yet, in freedom, its adhesion is evidently very slight. It comes on shore -
by hundreds, after a gale, on the. Devonshire coast ; and is frequently dredged on sandy
mud, sometimes adhering to a small bivalve-shell, but more commonly free, with the
posterior extremity contracted, so as to resemble a thick pedicel. It burrows in sand;
and, in conformity with such a habit, it has the power of great elongation. A Specimen
which I have kept for the last six months, sometimes forms a slender column 5 inches in
height. From this vermiform creature the transition is so brief to the free J. lyanthus,
that we hardly need to seek a place for intestinalis and vermicularis; and from Zlyanthus |
to the genera Peachia and Edwardsia, of which I have spoken in the former part of this
Memoir, and thence to the Sipunculide, the road is patent.

These relations I have attempted to display by a diagram ; though I need scarcely say,

“that such a representation cannot adequately express the varied consanguinities and .
eross-alliances of the grand plan of Nature. | |

XXXI. Hors Carcinologicæ, or Notices of Crustacea. I, A Monograph of the Leuco-
siade, with observations on the relations, structure, habits and distribution of the
family; a revision of the generic characters; and descriptions of new genera and
species. . By Tuomas Bunt, Esq., V.P.R.S., Pres. L.S. &c. ;

Read June 5th, 1855.

THERE is not perhaps another family amongst the whole of the Decapodous Crustacea
so distinctly isolated by its general characters as the Leucostanæ. Belonging, as they
obviously do, to the large tribe of Ozystomata, to which they are allied by the important
character of the form of the buccal cavity and the structure of the foot-jaws, they have in
many respects but little tangible affinity with any other family of that group, by means of `
intermediate aberrant forms, with the exception of a certain primé facie approach to the
Calappade in the genus Oreophorus, to which further allusion will be made.

And not only is there such a remarkable absence of any osculant form within the limits
of this very natural group, but there is a no less striking want of any obvious approxima-
tion to this type in the other families of the Oxystomata; for the relation suggested by
De Haan of the genus Matuta, or rather his family of Matutoidea comprising Matuta
and Hepatus, as leading to the Leucosiade, appears to me quite devoid of any sound
foundation. Still less appearance is there of any important approximation to the Rani-
nade, as suggested by the same learned writer. — Jti

I cannot, however, but believe that there is a structural approach to this family in a
genus which has hitherto been placed at a remote distance from it by all the authorities
on this subject, and particularly by Professor Milne-Edwards in his recent admirable
treatise, as it may be called, on the Catametopa. I allude to the genus Pinnotheres, which
in the work above mentioned is associated with the families Grapside, Gecarcinide, Ocy-
phat! &c., to which groups its affinity is probably much more slight than to the family
now under consideration. It will be reserved for a future occasion to examine into the real
relations of the somewhat anomalous family of the Pinmotheride ; but I would observe,
that the general aspect of the male Pinnotheres is so similar to that of a true Leucosia

as to be obvious at the first glance; and although I would not trust too much to external |
form and general character or aspect, I think these po on Bi sin idic ipi
rated. "There is frequently a physiognomical character, so to speak, which is Y o
some close relation of affinity, which ought not to be cast aside hastily and wi hou >
consideration as a mere analogical resemblance. I shall not on the present reprit x

The approach of the genus Oreophorus to the Calappade is, however, que ,

and in all probability constitutes a true relation of affinity. This remarkable genus was
first formed by Dr. Rüppell, who figures and describes a species, O. horridus*, found by
him in the Red Sea. Itis evidently constructed on a type approximate to the Calappade.
Like them it has the power of concealing the feet under the body, so that when at rest
they are protected by the margin of the carapace, which is somewhat dilated laterally.
In this particular it resembles Zthra, as well as Oryptopodia, Lambrus and others, with
which it has however no other near structural relation. The genus Nursia of Leach,
and the new genus Lithadia, which is closely allied to Æbalia, approach it in a slight
degree in this respect, and the latter still more in its general aspect and the extreme
rugosity of the body. | :

The tendency to a lateral dilatation of the carapace is indeed a very striking character
in several forms of this family. It has been already alluded to in reference to Oreophorus
and Zithadia: it appears also to a certain extent in PA/yria and Ebalia. But in Iphis
it assumes a very different form, terminating in a long acute spine on each side, recalling
in some measure the aspect of the genus Matuta; whilst in Iva a still more remarkable |
development is observed in an extraordinary lateral extension of the carapace itself, which
is twice as broad as it is long, besides its still further production into a somewhat cylin-
drical process on each side, the two processes together constituting about half the total
breadth. |

The characters of a group so distinctly marked could not fail to strike the accurate and
observant mind of Fabricius, who, in the course of his re-formation of the whole class,
brought together all the species which were then known of the Leucosiade into a single
genus, to which he gave the name of Leucosia. This name was retained by Leach for the
form which is evidently the typical one; and he arranged into several well-defined generic
groups the species thus associated by his predecessor, together with others with which he
had become acquainted. All Leach’s. generic divisions have received the sanction of
subsequent naturalists; and the only changes which have been introduced since his time
have consisted in the discovery of some new species}, if we except the mistaken application,
by Milne-Edwards, of the name of Guaia to certain species which Leach had already
designated under the generic appellation of Persephona. This mistake however was a
very natural one, arising from the vague and brief terms in which Leach had indi-
cated rather than described or defined them. The specific and even the generic characters
given by this distinguished naturalist are often, from an inordinate desire for brevity,
extremely vague and incomplete ; and now that the number of known species and of
generic forms has become so immensely increased, it is often in vain that we endeavour
to reduce to any certainty the contracted and indefinite phraseology in which his characters
are expressed.
. Tt is clearly of the greatest importance not only that the distinctive phrase applied to

e Harrovia and Tlos, genera described by Adams and White in the “ Crustacea” of the Voyage of the Samarang,
ela among the Leucosiade in that work, certainly do not belong to this family. Iphieulus is stated by those
authors to belong to the Parthenopide, although located in their work with the Leucosiade ; but as regards this genus,

= led, by ne of the specimens in the British Museum, to the conviction that it is in truth a Leucosian genus,
and that they are right in the text and not in the note,

MONOGRAPH OF THE LEUCOSIAD.E. 279

a species should be as tangible and certain as possible, but that every new species should
be fully, as well as accurately described in detail. In this respect Leach was generally
very deficient. The only indications left of many of his species and even genera, consist of
half-a-dozen words, in many instances so vague that they have become useless, and, as
they are often not illustrated by figures, it would be impossible to identify the species to
which they refer, were it not for the existence of the specimens themselves in the British
Museum. This is particularly the case in respect to the present family, of which Leach
gives many new genera and species in his valuable repertory the ‘ Zoological Miscellany ;’
.. butin so slight a manner that only the tickets applied to the specimens in the Museum
by Leach himself afford any sure index to the species intended.

.. This however is not the only fault to which naturalists are prone with regard to the
definition or description of new species. Nothing is more common than that the only
characters given are deduced from a comparison of the development of certain organs with
the same parts in nearly allied species. Such specific characters are always objectionable.
To describe an organ in one species as longer or broader or thicker than the correspond-
ing organ in another species for instance, infers the necessity of an actual comparison of
one with the other, which, of course, is often impossible. Specific distinctive characters
should always be either absolute, or derived from points of comparison within the indi-
vidual itself. Another defect from which much confusion has arisen, is the want of a full
detailed description of each species, which is necessary, however nearly it may be allied
to another; and this should include every organ of importance that can be easily and
certainly brought under review. The want of this desideratum has been the fruitful
source of errors in synonymy, and the cause of interminable and unsatisfactory research
and labour. I may be allowed to add, that the specific definitive phrase should be such
as to point out, as briefly as may consist with clearness and certainty, the points of
_ distinction from all those already known in the same genus; whilst the gosonriphon should
be so full as to enable the naturalist to ascertain whether any individual afterwards
observed is a.new species, or identical with that described.

The admirable work of Professor Milne-Edwards, which has been the text-book of every
student of this class of animals ever since its publication, contains such a general view
their organization as renders it unnecessary for me to enter into any ep
of their structure, particularly as that work is in the hands of every one gem -
subject. But in the fine work of De Haan on the Crustacea of J apan, : isis ed =

depends, that I will venture to quote the passage at length d viol cilia

I will now offer a few general remarks which may illustrate the bearing of their struc-
ture upon their habits. This structure is evidently not fitted for any rapid or energetic
movements such as belong to the Grapside and Ocypodide, in which these powers are
amply provided for by the robust form and development of the ambulatory pairs of legs;
nor does it afford any means of swimming, as in the Portunide, or still more in Matuta;
nor is it fossorial, as in Carcinus and many others; nor suited for climbing, as in the long -
slender-legged Leptopodiade ; nor for self-concealment, as in the Calappade. It appears |
that they must depend for their safety from external injury upon the protection of stones
and the hollows of rocks; for their claws have no power of defence, and the ambulatory
legs are comparatively slender and ineffective. The carapace in most of them however is
remarkably hard, and its arched form gives it additional power of resistance.

The extreme minuteness of the eyes would agree with the idea of their lurking and
somewhat stationary habits; and this, with the almost rudimentary form of the antennæ,
appears quite inconsistent with any high development of the functions of relation. In
entire agreement with the view I have taken of the slow and feeble movements of these
animals, as deduced from a consideration of the structure of the organs of locomotion, is
the diminished extent of their respiration, evinced by the reduction of the number of their
branchiæ to six pairs, whilst the foot-jaws and other manducatory organs are also small
and weak.

Of the habits of most of the animals of this family we have no recorded history;
but the account which that excellent observer Roux has given of the species of Tlia as
noticed by himself on the shores of the Mediterranean, is in exact accordance with the
structure I have described, and the functions which have been predicated from that
structure, Speaking of this genus, he says*, * Les Tlia ont le têt très dur ; ce sont des
Crustacés qui vivent solitaires, cramponnés parmi les Flustres et les Madrépores, ou sur
les écueils, à de moyennes profondeurs; leur marche est lente; ils manquent d'agilité ;
la forme de leur corps et la débilité de leurs pattes s'opposent à ce qu'ils puissent nager; |
on ne les voit courir qu'à l'aspect du danger.” And of I. nucleus he says, “ Ce décapode
. est extrémement timide; il habite les moyennes profondeurs coralligènes, d’où il ne sort

que lorsque le hasard lui présente quelque proie facile à saisir. Tl ne s’approche jamais
des rochers du rivage, On le rencontre rarement parmi les algues, si ce n'est en Mars,

y el distribution of the Leucosiade is as remarkable for the restriction of
- s > which it is composed to special localities, as is the whole family with respect —
gical relations, which have already been considered. Every genus, without

exception, is restricted to its own geographical limit. There is not, I believe, a single
instance of one species of any genus inhabiting the Old World, and another of the same
genus being found in the New. The numerous species of what may be considered the
typical form of the family, Leucosia, are without exception inhabitants of the Eastern seas,
ranging from the south of Australia by the Indian Ocean, the Philippines, New Guinea,
Borneo, the coasts of China and J apan; but strictly circumscribed to these limits, The
genera Myra, Philyra, Myrodes, Platebalia, Txa, Iphis, Iphiculus, and Arcania are also
confined to the same seas. Of Oreophorus one species is found in the Red Sea, and the
other has been taken in the Straits of Sunda. balia is, as far as we are at present
informed, confined to the tract including the coasts of Great Britain, “ La Manche,” and
the Mediterranean; and so much is it especially a British genus, that Professor Milne-

. Edwards, when he published his great work, had never seen a specimen of either of the

x

three generally known species, excepting those in the British Museum, all of which were
natives of this country; nor does he mention a specimen of either of them as then exist-
ing in the Paris Museum. Jia is exclusively Mediterranean. The numerous species of
Persephona, and the new genera Leucosilia and Lithadia, are strictly American, and are
principally found on the Eastern coasts and the Galapagos Islands.

The majority of the species in this family are found at no great depth.

I know of scarcely any family of Orustacea, our knowledge of the species of which has
so much increased of late years as this. When the great text-book of the class, the
admirable work of Milne-Edwards, appeared, there were only known to him twenty certain
Species arranged in eleven genera. The great work of De Haan on the Crustacea of Japan
added several others, and the list has been increased by Messrs. Adams and White in
their description of the Crustacea from the voyage of the Samarang. The collections
made by Mr. Cuming in the Philippine Islands and by other voyagers, have placed within
my reach numerous others, some of which are in my own collection, but the greater number
are in the British Museum; and I have to express my thanks to Mr. Adam White for the
exercise of his well-known courtesy and attention in assisting my access to the treasures
of that fine collection. In the present Monograph I have been enabled to add no less
than thirty-six new species, thus more than doubling the number prey sanaly known ; the
whole number now known and included in the present Monograph being sixty-five, con-

stituting eighteen genera.

The genus Leucosia must be considered as the type of the family; nieder

perhaps generally, the case with a typical genus, it includes a much larger number of

282 MR. BELL, HORÆ CARCINOLOGICÆ ;

species than any other. Its characters are so defined, that none of the species exhibit any
approximation to another generic form. The genera Myra and Persephona, and Ilia and
Leucosilia, have so much that is common to them all in their structure and general aspect,
that it requires close examination to determine their limits; but in Leucosia, numerous
as the species are, not only the essential characters of the parts on which the generic
distinction usually depends, but also the general features of the whole form, are remarkably
similar in all the species, and obviously distinct from all others,

There are indeed in this genus many interesting points in the general form and colour
and other less essential characters, which although not of much physiological or functional
import, are curious as exhibiting coincidences which in many cases serve to indicate a
close relationship as strongly as those modifications of organs and functions which have
a more important bearing upon the habits of the species, and are commonly considered as
essential. The polished carapace ;—the absence of all hairiness or other clothing, which
is universal, with the exception of two species, L. Whitei and unidentata, in which a small
quantity of close hair exists amongst the tubercles of the arms ;—the existence of large and
distinct granulations, or rather tubercles, generally distinctly coloured, upon at least the
proximal part of the arm, extending forward in lines more or less numerous ;—the tendency
to a brown or purplish-brown colour in most of the species ;—and the occurrence, in very
many, of spots occupying the same situation on the carapace, four of which are paler
than the ground colour, and placed at the anterior part on the gastric region, and two
dark ones upon the posterior portion of the branchial ;—these are amongst the characters
of minor consequence to which I have alluded, and which, without having any bearing
upon function or habit, are interesting from the constancy or frequency of their occurrence,
and as indicative of certain structural or formal tendencies throughout the whole genus.

There is also one remarkable peculiarity which exists in almost all the species of Leu-
cosia, but I believe in no other genus, the variations of which constitute good specific
characters. This is a sinuous groove running along the side of the thorax, bounded above
by the lateral margin of the carapace, and beneath by the upper edge of the epimeral
plate; the former loses itself in the posterior part of the branchial region, the latter is
continued into the posterior margin of the carapace. It commences in front of the first
pair of legs, where it forms a single or double notch, or a deep, almost circular cavity.
Its margins are usually tuberculated, and the tubercles are ordinarily largest at the ante-
rior part. A very few species, as for instance L. orbicularis, have no such groove, the epi-
meral piece or space between the lateral margin and the junction of the carapace with the
sternum being plain and smooth. De Haan is the only author who has noticed this
curious structure, and he has only mentioned its anterior limit, which he terms “ incisio
ante chelarum insertionem.” This expression, however, gives no idea of its true extent or
course; and I have called it “sinus thoracicus,” as more expressive of its character, and
more easily available in specific description. Of its use I can offer no suggestion. It does `
not appear to have any connexion vith the interior of the body, nor can it be supposed to
have any important office, as in some species it does not exist.

In the year 1837, when Professor Milne-Edwards published his * Histoire Naturelle des
Crustacés,’ two species only of this genus were distinguished, L, Urania and craniolaris.

MONOGRAPH OF THE LEUCOSIADA. 283

These were both known to the earlier naturalists. One of them is figured by Rumphius
and Seba, and both by Herbst in his great repertory of crustacean animals, Fabricius
Lichtenstein, Leach, Desmarest, and others down to Edwards, have restricted their potios
to these two species. De Haan, in his admirable work on the Crustacea of Japan, fori:
ing a portion of the great work of Siebold, adds four species, and Messrs. Adams and
. White have described a seventh in the Voyage of the Samarang. The additions, however,
which have recently been made to the carcinology of the Eastern Seas by Hinds, Macgil-
livray and others, and especially by Mr. Cuming in his Philippine voyage, have enabled
me to swell the list of distinct species to no fewer than twenty.

The colouring of this species is remarkable. Of a general pale brownish-grey ; the
front, and a large mark proceeding backwards from it are white; two large spots on the
posterior part of the carapace, and two smaller ones on each lateral margin, the articula-
tions of the fore legs, the basal portion of the fingers, and a ring on each joint of the
ambulatory feet, are all of a more or less deep orange colour*. j
Specimens of the species are not unfrequently brought with other objects from China,
and these are almost always deprived of the abdomen, for the purpose of cleaning the
interior. | 22
The tubercles on the arms are disposed in a remarkable manner. On the upper side
near the base there is a congeries of about five or six small ones, and immediately in front
of them four large ones disposed in a quadrate form. On each margin there is a series of
tubercles, which are large near the base, diminishing forwards. The anterior portion of

the three sides is free from tubercles, excepting on the margins.

middle tooth being longer than the lateral; the thoracic sinus terminates anteriorly in a
notch, which reaches upwards to the margin of the carapace between the hepatic and |
branchial regions. The abdomen is long, lanceolate, and slightly hastate at the base.
This is one of the two species so often figured and described, and the only ones known
until within the last few years. It is very probably the Cancer craniolaris of Linnæus,
and certainly that figured under this name by Herbst; it is the Leucosia craniolaris of
Fabricius and all subsequent authors. There are several specimens in the British Mu-
seum, in the Banksian Collection of the Linnean Society, and in my own collection. It
inhabits the Eastern Seas, being found on the coast of China, &e.

There are several other species which resemble it in some degree in general form and.
proportions, but the paucity of tubercles on the arm sufficiently distinguishes it from them
all, excepting L. rhomboidalis of De Haan, which is certainly very nearly allied to it, but
differs in the hairy surface of the arms.

This species, of which a single specimen exists in the British Museum, differs from all
others that I am acquainted with in the very distinct punctuation of the whole surface of
the carapace. The arm also is covered with minute granulations at the anterior portion,
which in most species is quite smooth. In other respects it very much resembles the
following species, L. affinis. Its habitat is not absolutely known, but it is in all proba-
bility from the Indian Ocean.

Of this pretty little species there are three specimens in the British Museum, from the
Chinese Seas. It is easily recognizable at first sight by the thin, somewhat reflexed,
smooth margin of the carapace, and the wholly granulated surface of the arms, characters
which I believe do not exist in any other species of the genus. The buccal opening, and
consequently the external foot-jaws, are remarkably broad anteriorly.

This is certainly the most extraordinary known species of Leucosia. The form of the
legs, and particularly of the hands, which suggested the name, at once distinguishes it
from all others; but the most remarkable anomaly in its structure is the extent of the
buceal opening, and the corresponding development of the external foot-jaws, the length of
which nearly equals that of the portion of the body posterior to them. This peculiarity will

be appreciated when it is recollected that in the normal forms the relative proportion is

not more than one in three. Whether this structure has any relation to the habits of

the species, we have no means of ascertaining; but it would appear probable that such a
marked anomaly could scarcely exist in mere obedience to those abstract laws of structural
variation, which are often as difficult of solution as they are certain in fact.

I refer to the admirable figures by Roux, in his * Histoire des Crustacés de lg Méditer-
ranée,’ for a clear exposition of the characters of these two species, the only ones of the
genus yet known. I cannot believe that Tlia punctata of Edwards belongs to this genus:
at all. The figure in Herbst of Cancer punctatus, on which he has partly founded it, is |
undoubtedly that of a species of Myra, as is shown even by the form of the pedipalps, and
it may possibly be that of M. carinata of this memoir. The species provisionally named
Ilia Marianne by Herklotz, and figured by him from a specimen in the Louvain Museum,
is obviously not an Ilia. The foot-jaws and abdomen it appears were wanting in the spe-
cimen, so that it would be difficult to state what may be its generic relation; but it has
the appearance of Myra, or still more of Myrodes ; or it may possibly offer a new generic
type, as suggested by the author above-named.

Genus PERSEPHONA, Leach.

The characters of this genus and those of the species named by Leach were so im-
perfectly given by him, in the * Zoological Miscellany, that Milne-Edwards, not having
access to the specimens themselves from which they were derived, was fain to content
himself with simply translating them, being wholly unaware that they referred to a
previously well-known species, and in fact he gave to that species the generic name of
Guaia. I have, I believe, been able successfully to unravel this complication by an

examination of the numerous specimens in the British Museum, to which Leach’s names
were attached.

After a careful collation of the specimens in the British Museum, I have found myself
compelled to come to the conclusion, that all those which had been designated by Dr.
Leach as of two distinct species, and named respectively P. Latreillii and P. Lamarckii,
are in fact specifically identical. "They vary only in a slight degree in the prominence of
the angular ridge on the pterygostomian region; and even his own specific distinction
goes no further than the meagre expression, in the one case, “angulis subangulafim dila-
tatis," and in the other, “ angulis anticis gradatim et obtuse dilatatis." It appears that
all the specimens which were in the collection at that period were entirely faded, so as to
have lost that striking and beautiful marking which would have enabled him to identify
them with Herbst's figure. Browne gives no indication of these markings, either in his
figure or in the letter-press. It is also remarkable that Leach should have been un-
aware that those specimens were originally in the Sloanian Collection, and therefore
brought from the West Indies. As the nomenclature has thus become confused, I have
ventured to change the specific name; and retaining the generie one given by Dr. Leach,
have adopted for the species the name Guaia, which Milne-Edwards had applied gene-
rically. : |

I find that in this genus, as well as in many others, the relative position of the three
posterior spines affords a very fixed as well as tangible specific character. In the present
species, the middle spine is but little higher than the lateral ones, which are very distant ;
whilst in Lichtensteinii the three are much nearer to each other, and form almost an equi-

lateral triangle.

very convex, with a broad central carina. The whole body above and below, with the
exception before stated, covered with large granulations. Anterior legs much resembling

The grounds upon which I have considered it necessary to constitute this species a
separate genus from. those with which it is most nearly allied, particularly from Perse-

phona, are perhaps rather to be found in its general habit and aspect, than in any very

prominent distinctions in the structure of those organs upon which the generic characters

are usually understood to depend; although even in these essential respects there are

sufficient peculiarities to justify the separation. It is impossible not to be struck at first
sight with the remarkable globular form of the body in each sex, so different from the

oval form of Myra and of the male of Persephona, as well as from the depressed character

of both sexes of the latter genus; whilst the existence of only a single small pang on
the posterior part of the carapace removes it obviously from all the species of ; ^ ese
genera, which have invariably three teeth at that part ; and from Ilia, in which there are

four. The general form of the body approaches the last-named genus ag a roid
other, but i its more important characters it is essentially different from it. From Per-
en the antennary fossæ, and consequently in that of the front,

sephona it differs in the form of ud

Of this genus a single species only has hitherto been described; namely, Myra fugax
of Leach (Leucosia fugax, Fabr.). To this I have now to add four new species, of all of
which there are specimens in the collection of the British Museum and my own. In this
genus there is a close resemblance on the one hand to Tlia, and on the other to Perse-
phona. To the former it is connected by M. fugax, and to the latter by M. mammillaris;
but from both it is distinguished by characters sufficiently marked. From Jia it is at
once known by the absence of the peculiar twist of the hand, and from Persephona by the
dilatation of the external stalk of the pedipalps. The five species are all natives of the
Eastern Seas.

There is considerable doubt as to the identity of this species with the figures above
referred to of Brown and Herbst, as well as with the Cancer punctatus of Linnæus. The
figure of Herbst very possibly belongs to M. carinata of this paper.

Carapace ovate, minutely granulated, particularly at the posterior part, distinctly but
slightly carinated along the centre; the hepatic ridge and lateral margin granulated, the
former having a small tubercle; the pterygostomian tooth broadly triangular; the cen-
tral spine on the intestinal region at least three times as long as the lateral ones, which
are conical and acute. The anterior pair of legs in the female twice the length of the
carapace, exclusive of the spine; the arm covered with tubercles; the hand slightly tumid
near the base, but less so than in M. fugax, narrowed forwards; fingers closed through-
out their length, finely toothed. Abdomen in the female with the fourth, fifth and sixth
segments united, as in M. fugax. |

Length of carapace 1 in.

The most obvious distinction between the present species and the one previously known,
consists in the carinated form of the carapace, which, although not very strongly marked,
is quite distinct, and differs obviously from the rounded surface of JL fugax. | Another
important distinction is in the comparative length of the three spines on the hinder part
of the carapace, the central one being in the present species so much longer in proportion
to the lateral ones than it is in the former. Whether this is the species figured by Herbst

as Cancer punctatus I am not sure, but it resembles very closely his figures assigned to
that species. As Professor Milne-Edwards refers to that authority for his Ilia punctata,
and as those figures certainly do not represent an Tlia at all, I am inclined to doubt the
existence of such a species of that genus, and to refer it to Myra.

Carapace oval, somewhat produced before and behind, the surface polished, and studded
with numerous small distinct globular tubercles, which also form a line along the
middle of the back, around the margin, on the hepatic region, and on the pterygostomian
crest. Front somewhat waved, slightly emarginate, a small tooth over the inner canthus
of the orbit. The teeth on the posterior part rounded, not longer than broad, the lateral
ones compressed. External foot-jaws tuberculated on the anterior portion, the palp some-
what dilated outwards. Sternum with lines of minute tubercles anteriorly. First pair
of legs in the male twice the length of the carapace, stouter than in the other species of
the genus; the arm covered with depressed tubercles; a scabrous line on the inner mar-
gin of the wrist, and on the outer and inner edge of the hand ; the fingers half the length
of the hand, suleated and scabrous. The remaining legs filiform, slender, the surface
punctated, the terminal joint awl-shaped, sulcated.

Length of carapace 2 in.

Of this fine species there are several specimens in the British Museum and in my own
collection. It was brought from South Australia. Its primá facie relation to Perse- '

phona is striking, but it differs from that genus in the essential generic characters, par-
ticularly in the form of the hand, and of the palp of the external foot-jaws. |

Myra variegata of Rüppell (Krabben des Roth. Meeres, p. 17. t. 4. f. 4) is not a Myra, `
but is probably a young individual of a species of Philyra.

This genus, which is nearly allied to Myra, differs from it in the following particulars.
The antennary fossæ are less oblique in their direction, being so placed that the anten-
nules lie nearly longitudinally.. The palp of the external foot-jaws is merely curved on its
outer edge, instead of being first dilated and then distinctly narrowed towards the apex,
as in Myra. But the most remarkable peculiarity is in the form and length of the ante--
rior legs, which in Myra are almost filiform, and, even in the female, more than twice as
long as the carapace; whilst in the present genus they are not longer than that part, if in
both Cases we except the fingers. The hand especially, which in Myra is always many
times longer than it is broad (in M. fugax & not less than seven times), is in Myrodes as

MONOGRAPH OF THE LEUCOSIADE: 299

broad as it is long. The fingers differ from those in any other genus of the family,
with the exception of Nursilia, in their beautiful tenuity, their curvature, and their
hooked points, which cross each other considerably when closed. :

This genus may be considered as bearing the same relation to Myra, as Leucosilia does
to Persephona; and as Myra and Persephona represent each other in the different hemi-
spheres, so may Myrodes and Leucosilia.

I have received a large number of this interesting species from Port Adelaide in South
Australia. The males and females were nearly equal in number. It may be at once
distinguished from every other hitherto known, by the absence of all appearance of granu-
lations on every part of the body, and even on the arms. There are also some specimens

A genus very nearly allied to Æbalia, but distinguished from it by several obvious
charaeters; as the three tubercles on the posterior margin of the carapace, the rounded
notch in the superior margin of the orbits, the communication of these cavities with the
antennary fosse, and the form of the external foot-jaws. There are three species in the
British Museum, two of which are from Port Jackson, and the third from New Zealand.
The latter, P. levis, differs considerably from the other two, but must be referred to the
same genus.

The generic characters are much less strongly marked in this species than in either of
the others, but the form of the foot-jaws, the three teeth on the posterior margin of the
carapace, its rhomboidal form and other points of structure, sufficiently show its close
relation to them. It may be considered perhaps as osculant between this genus and
Ebalia.

The grounds upon which I have thought it necessary to assign a distinct generic rank
to the species to which the above characters belong, closely allied as it is to Ebalia, are
the extremely different general aspect of the whole animal, arising from the rough and
strong prominence of the different regions, the projeeting spines, the large and prominent
granulations, so unlike any other form in this family, excepting Oreophorus, and some
distinct though not very striking differences in the form of the external foot-jaws, the legs,

and particularly the abdomen in the male.

This genus, established by Rüppell, constitutes the sole form of the present family
which can be considered as offering a distinct approach to any other in its general
characters. Its relation to the Calappade, and particularly to the typical genus of that
family, has been already adverted to; and the principal character by which it is allied to
that group, and by which also the genus Calappa is distinguished from its congeners,
namely the latero-posterior expansion of the carapace, by which the ambulatory legs are
capable of being concealed, obtains in all the species at present known. The species first
discovered, and on which the genus was founded by Dr. Rüppell, was described and
figured by him in his work on the Crustacea of the Red Sea. A second species was
obtained by Mr. Adams in the Straits of Sunda, and appears in the Natural History
(Crustacea) of the Voyage of the Samarang; and a single specimen of a third, now first
described, the habitat of which is unknown, exists in the British Museum.

There is a certain approach to this genus in the general aspect of Lithadia, particularly
in the hollows and elevations of the shell.

The discovery of two other species since Rüppell’s publication has rendered a new spe-
eifie distinctive character necessary. The strong deep carina extending obliquely across

each branchial region distinguishes it from both the others, and the comparatively normal
form of the claws from O. reticulatus. |

hepatic region, a large prominence on the anterior, and a double one on the posterior part
of the branchial region ; front emarginate. External pedipalps with the outer stalk slightly
arched; the inner with a longitudinal groove close to the inner edge, and a slight carina

slender, curved, and shorter than the hand. The abdomen is wanting in the only specimen
known, which is a male.

I have no doubt whatever that Herbst’s figure belongs to this species. It is consider-
ably broader in proportion to the length than the specimens in the British Museum, but
these also differ in this respect from each other. I have restored Herbst’s name, which I
do with the less hesitation, as his is the only original figure which has hitherto appeared,
and we have no other original notice of the species than the short but correct and ex-
pressive description given by Leach. I have also given a figure of the species on account
of the imperfection of that of Herbst. The specimens in the British Museum, which are
the only ones with which I am acquainted, were brought from India by the late General
Hardwicke. ‚These differ among themselves in some particulars, but, as it appears to me,
not sufficiently to justify a specific distinction.

an obtuse elevated line runs down the middle of the carapace from the front to the cardiac
region, crossed by a transverse one which is granulated, commencing between the anterior
and posterior lobes of the branchial region, and crossing over the genital. The anterior
legs (in the female) are of moderate length, the hand not one-third longer than broad,
with two granulated lines on the upper side; the fingers short, meeting at the greater part
of their length, but with a hiatus near the base. The external foot-jaws have the outer
stalk or palp considerably curved, rounded at each extremity; the inner stalk with the
internal margin straight, meeting its fellow the whole length. The abdomen in the
female (the only sex I have seen) broad ovate, the fourth, fifth and sixth segments
united, and indications of them in slight transverse depressions.

This genus has a close affinity with Nursia, but differs from it in the form of the pedi-

fingers is very different, resembling almost exactly that of Myrodes.

A close examination of the specimen in the British Museum, described by Messrs.
Adams and White as “ Iphis,” has fully confirmed the impression I had received from
their figure that this is a true Arcania. Its general form is that of this genus, differing
greatly from that of Iphis; and its resemblance to A. undecim-spinosa of De Haan is very
close. In fact it scarcely differs excepting in the number of spines.

Approaching Iphis in form, particularly in the transverse diameter of the carapace a
little exceeding the longitudinal, and being furnished with two lateral spines longer than
the others. The spines in this species, as in Arc. tuberculata and Erinaceus, are them-
selves tuberculated. The posterior pair of marginal spines, which are flattened, show this
character in a very beautiful manner, as is seen in the figure (d). The anterior legs are
slender, the arm slightly curved, covered with tubercles; the hand smooth, swollen at the
proximal portion; the fingers very thin, curved, nearly as long as the hand, toothed, and
meeting only at the points. The remaining feet are wanting in the specimen, excepting
one, and the rest have been added in outline in the figure, from the nearly allied species.

A careful examination of all the specimens of this genus to which I have access,
amounting to about twelve, has led me to conclude that they all belong to I E

312 | MR. BELL, HORÆ CARCINOLOGICA ;

The form and size of the lateral process vary considerably. In some it is cylindrical, in
- others it is somewhat conical; in some it is either direct or even bent slightly backwards,
in others the apex is turned forward ; in some there is a filiform appendage at its apex, in
others there is not a vestige of this armature. The degree of granulation of the different
parts also varies.

With respect to I. inermis of Leach, I see no difference but what might be supposed to
depend upon great age; and the distinction is really less on examining the actual speci-
mens, than appears to be the case from merely a comparison of the figures. Under these
circumstances, I have ventured to give the references to the three supposed species, as
synonyms of the old Cancer Cylindrus of Fabricius. |

I have already observed that the genus Harrovia of Adams and White has no rela-
tion whatever to the present family. Iphiculus of the same authors, arranged by them
amongst the Levcostapa, but stated in the same place to belong to the PARTHENOPIDA,
appears to me to be nearly allied to the former family, and most probably associated with
them. Certainly it has no near affinity with the PAmrHENOPIDX. Tlos may be safely -
considered as allied to the LEUCOSIAD.E. Unfortunately, neither the eyes, the orbits,
the antennulæ, the antennary fosse, nor the foot-jaws, are mentioned in the generic
characters, or figured in the plates. See the Crustacea of the Voyage of the Samarang,
pp. 55, 57. pl. 12. f. 5, pl. 13. f. 2. 5.

It is only since the foregoing paper has been in the press, that I have had an oppor-
tunity of seeing the magnificent work of Mr. James D. Dana, on the Crustacea obtained
in the United States exploring expedition under the command of Mr. Charles Wilkes f — —
the United States Navy. This work reflects equal credit on the author, and on the — |
American Government for the liberal and handsome manner in which it has been
published. |

In this publication two species only are described as belonging to the present family,
and of these one appears to me at least very doubtful as to its relation to it. I shall
quote the characters of both as they are given by Mr. Dana :— 3

* [PHIS LONGIPES. Carapax parcè granulosus, suborbicularis, non latior quam longus
[longior}, armatus spinis duabus longissimis lateralibus latitudine carapacis n
brevioribus (unà in latere utroque) et duabus minutis antero-lateralibus, duabus
parvulis postero-lateralibus, et unà posticà corporis dimidium longitudine fere
æquante. Frons bilobatus parc prominens. Pedes 8 postici prælongi.”? |

Iphis longipes, Danä in op. cit. p. 396. t. 95. f, 4.

i Taken from the stomach of a Tetraodon, among the reefs of Vití Lebu, Feejee Islands."

Of this species I have only to observe, that its form and characters rather tend to in-
d a doubt which I have before entertained of the propriety of generically separating.
e species of Iphis and Arcania. They appear to pass into each other by the present

species on the one hand, and by Iphis novem-spinosa of Adams and White, which I have
already transferred to Arcania, on the other. »

MONOGRAPH OF THE LEUCOSIADA. 313

Genus Nucıa, Dana.

“ Carapax parcè transversus, anticè non productus, latere non dilatatus, inermis superficie pauld tuber-
culatus, fronte bilobatus et non saliens. Oculi pauld remoti, grandiores, cdi giai hers buccalis
bené triangulata. Maxillipedis externi articulus 3tius triangulatus; palpus angustus, extüs rectus.
Pedes toti breves, et crassi, digiti in plano subverticali claudente, eodem cum manus articulatione."

NUCIA SPECIOSA, Dana, /. c. p. 397. t. 25. f. 5.

It is unnecessary to quote the description of the only species upon which this genus is
. founded. It appears to me that it is scarcely admissible into the family of LEUCOSIADÆ,
on account of the extraordinary size of the eyes, the thickness of the legs, and other
characters, no less than the general form and aspect of the body. I give this opinion
with deference in the absence of an actual specimen.

Sciences at Stockholm, for Archbishop Troil, by him presented to Sir Joseph
Banks, and now presented to the Society by Robert Brown, Esq., President, for
which the Special Thanks of the Society were directed to be given.

It was moved by Dr. Wallich, seconded by Dr. Boott, and unanimously

resolved :—
That the most grateful and cordial Thanks of the Society be offered to Mr. Brown,
for the admirable manner in which, for more than three years, he has conducted the
business of the Society as its President ; together with the great and sincere regret of the
Members that advancing years and the infirmities attending on them should have in-
duced him to relinquish an office, in which it would have been their earnest desire long

to have availed themselves of his invaluable services.
