MONOGRAPH OF THE GENUS
CONUS.
Iy the following arrangement of species, | have endeavoured to
bring together those most nearly resembling each other, to facili-
tate comparison. In doing this I have found the gradations so
subtle as almost to defy any systematic division into defined
groups. ‘There are no single characters which can be depended
upon with any certainty in determining the affinities and distine-
tions either of groups or species. It is more by the eye, taking
in an assemblage of characters, and regarding the general appear-
ance, that they can be appreciated. Thus, although for conveni-
ence I have followed a prevailing custom in placing by themselves
in groups nearly all the coronated species, yet there still remain
some coronated species whose general characters forced me to
place them in widely different groups, while some generally coro-
nated species present varieties in which the whorls are smooth.
This is only one instance of what occurs with regard to almost
any character that can be named, such as length of spine, granu-
lation, ete. Under these circumstances it is impossible to main-
tain perfect consistency as to retaining and proposing some spe-
cies and rejecting others. As the collector’s great object however
is to know the shells, I have preferred in most cases giving the
species as they stand, stating the alleged differences, and leaving
the final decision to individual taste. Thus, some eight or ten so-
called species of the ¢ewti/e group, are, to the best of my belief,
mere variations of one type; yet I have admitted them in the cata-
logue, simply stating the points in which they are said to differ.
a. Coronated, turbinated, straight-sided.
1. mperraris, Linn.—C. oblongus, tuberculis magnis corona-
tus, medio subcontractus, versus basin attenuatus; albus, czeruleo
VOL. It. B
2
tinctus, castaneo bifasciatus, punctis et lineis interruptis cinctus
(Plate I. f. 2).—The interrupted lines are coincident in downward
flashes, and united by two chestnut bands; coronal tubercles
large.
2. guscatus, Born.—C. C. imperiali similis, sed flammis cas-
taneis longitudinalibus magnis ornatus (f. 3).—In this species
the downward flashes are large, dark, and defined, while the inter-
rupted cross-lines are less prominent.
3. viripuLus, Lamk.—C. C. imperiali similis sed brevior,
flammis longitudinalibus subviridibus angustatis (f. 1).—Rather
shorter than the two preceding, with the downward flashes narrow
and greenish.
4. marmornus, Linn.—C. oblongus, tuberculis magnis coro-
natus, medio subcontractus, albus, roseo tinctus ; lineis nigrescen-
tibus semicircularibus pictus, interstitiis cordiformibus (f. 5).—
The ground is tinged with rose-colour, and the whole surface is
reticulated with semicircular lines, leaving heart-shaped interstices.
5. Banpanus, Brug.—C. C. marmoreo similis, sed maculis tri-
gonis castaneis reticulatus, medio leviter bifasciatus (f. $).—The
shell is generally straighter, and the chestnut markings broader,
particularly in two central zones. Probably only a variety of C.
MAT MOVEUS.
6. nocrurnus, Brug.—C. C. marmoreo similis, sed colore ni-
grescenti pictus, interstitiis cordiformibus, albis, paucis (f. 4)—
Probably another var. of C. marmoreus, in which the dark colour-
ing nearly covers the shell.
7. Desurcutm, Sowb.—C. subyentricosus, versus basin angus-
tatus, nodulis contractis coronatus, albus, roseo tinctus, fasciis latis
duabus castaneis et lineis cordiformibus pictus; variat granulatus
(f. 6, 7).—Coloured like C. nocturnus, and usually considered as
a variety, but it is bottle-shaped, and the crowning nodules are
contracted into rounded nipples. The smooth variety (f. 7) is in
the collection of Mrs. Deburgh, who first remarked it as a distinct
species.
8. vipua, Reeve-—C. quam C. marmoreus brevior, ad angu-
lum rotundatus, ad basin contractus; fusco angulatim minuté
reticulatus (f. 9, 10).—Shorter and more contracted at the base
than C. marmoreus, with the angular reticulations more numerous
and fine.
9. Nicosarscus, Bray.—C. oblongus, lateribus rectis; spira
DSs|
3
concavi, nodulis acutis coronati; albus, luteo tinctus, lineis et
maculis nigrescentibus reticulatus (f. 11, 12).—The depressed
spire and sharp coronal tubercles, with the dark and sharp reti-
culated markings, distinguish this shell from C. vzdua on one side
and C. Nicobaricus on the other.
10. aracHNorpeus, Gme/.—C. oblongus, lateribus paululum
inflatis, roseo tinctus, rubro-nigrescente minuté reticulatim linea-
tus, medio plus minusve bifasciatus (f. 14).—Minutely reticulated
with dark reddish lines.
11. Pertum, Chemn.—C. quam C. arachnoideus brevior, ma-
culis trigonis angulatis castaneis minuté seriatim pictus; variat
bifasciatus (f. 13; f. 390).—A shorter shell than C. arachnoideus,
with close-set camp-like markings. The banded variety (f. 390)
assists the identification with Chemnitz’s shell.
12. zonatus, Brug.—C. oblongus, corond obtus4; spira brevi,
ceruleo maculata et bifasciaté, nigro lineat& (Plate Il. f. 15).—
This species is distinguished by the regular cross-lines and the
tessellated bluish markings and bands between.
13. aLpicans, Sows.—C. oblongus, lateribus rectis, ad basin
angustus, albus, ad basin fusco tinctus, corona indistineta (f. 98).
—A small, straight-sided, white shell, tipped with brown.
14. tenuis, Sowb.—C. oblongus, tenuis, albus, ceruleo tinc-
tus, ad basin castaneo tinctus, ad angulum spire et in medio cas-
taneo punctatus; spird elevaté, nodulis momiliformibus coronata
(f. 314).—A light, thin, bluish-white shell, with bead-lke crown,
and two rows of chestnut spots.
15. Rectuzranus, Bernhardi.—C. elongatus, tenuis, medio
subcontractus, ad basin subattenuatus, pallide luteus seu roseus,
maculis evanidis bifasciatim cinctus; spiri acuta, leviter coronata
(f. 88, 39).—A light shell, with sharp angle and elegantly taper-
ing form.
16. Carntanp1, Kien.—C. solidus, oblongus, ad basin attenua-
tus; spird depress’, tuberculis paucis coronata, inter nodulos cas-
taned; fulvus, lineis castaneis cinctus (f. 34).—The flat top,
cross-lines, and attenuated form of this rare shell distinguish it
sufficiently from all others.
17. Motiuccensts, Chemn.—C. solidus, subpyriformis, luteus,
castaneo maculatus, seriatim granulatus ; spiri convex4, tuberculis
magnis coronata (f. 46).—A rather pyriform shell, with convex,
coronated spire, and granulated surface.
4
18, unicotor, Sowd.—C. elongatus, purpureo tinctus, inferne
substriatus; spiri convex4, anfractu ultimo distanter coronata
(f. 83).—A peculiar shell, of a fawn-colour tinged with purple,
spire convex, crowned with distant nodules.
19. murtouzatus, Sowd.—C. oblongus, solidus, seriatim gra-
nulatus; spiri convexd, maculaté, obtuse coronata; albus, ad ba-
sin ceruleo tinctus, medio castaneo laté bifasciatus (f. 89)—With
a spotted, obtuse spire, granulated surface, light chestnut broad
bands in the middle, and blue at the base.
20. caLatus, 4. dd.—C. parvus, transversim sulcatus, sulcis
longitudinaliter striatus; albus, aurantiaco laté reticulatus; spira
depressii, apice acuté elevato, anfractibus minuté coronatis (f. 107).
—Marked lke the Marmoreus group, but encircled with deep
grooves, striated across.
21. tivipus, Brug.—C. solidus, fulvus, interné et ad basin
ceruleus, medio et ad angulum pallidus; spird convex’ mediocri-
ter coronaté, apicé acuto (f. 27).—The well-known blue-tipped
obtuse species.
22. suerniatus, Reeve.—C. C. livido similis, sed spira castaned,
subeanaliculata, test fasciati (f. 50).—Although the banding
is more distinct and the whorls of the spire more canaliculated,
I think this is but a variety of C. Zividus in a young state. Ina
series of specimens the distinctions are lost by gradation.
23. crrrinus, Gme/.—C. subpyriformis, breviusculus, medio et
ad basin distanter granulatus, mterne et ad basin purpureus;
spird obtusé coronata (f. 70).—I think the young of C. dividus
is straighter than this shell, and Quoy, who names it C. sanguino-
lentus, describes the animal as of a bright red colour.
24. optus, Reeve.—C. angustatus, levis, luteo-olivaceus, su-
perne ceruleo-albi, medio fascia pallidi cimctus; spird convexa,
minute coronati; fauce et basi violaceis (f. 37, discoloured, and
f. 100).—The narrowed form and minute coronation distinguish
this from C. fividus.
25. pisrans, Brug.—C. elongatus, medio subcontractus, basi
attenuatus, fulvus, pallidé zonatus, versus basin leviter elevatim
striatus, violaceo-nigrescente tinctus; spird convexd, nodulis ob-
tusis albidis coronati, interstitiis fuscis, apice truncato; fauce
grisei (f. 28, 29).—Remarkable for the peculiar depression of
the apex and the white nodules of the spire interlined with dark-
brown.
5
26. BaLTEATUS, Sows.—C. breviusculus, subtrigonus, fulvus,
minuté striatus; ad basin et interne violaceus (f. 71).—Resem-
bling C. citrinus or C. lividus, but finely striated.
27. TaBrpus, Reeve.—C. subpyriformis, tenuis, minute sulca-
tus, ad basin sulcis fortioribus, distantibus; colore pallido (f. 108).
—A\ pale, rather pyriform shell, finely striated above and distantly
suleated below.
28. crepuscuLuM, Reeve.—C. fulvus, ad basin ceruleo tinc-
tus, superné levis, infra minuté granulatus; spird acuminata, an-
gulo minutissimé nodulifero (f. 96).—Like C, Zivédus in the blue
tip, but a lighter and more angular shell.
29. cranirer, Feeve.—C. subfusiformis, granosus, pallidus ;
spird subcanaliculataé, apice fusco (f. 109, 110).—Our second
figure is too darkly coloured. The shell is granulated in every
part, and towards the base in ridges.
30. arcuirHaLassus, D2d/w.—C. solidus, vix ventricosus,
albus, flavido minutissimé reticulatus, castaneo fasciatus, fasctis
et interstitiis maculis cordiformibus albis inspersis; variat granu-
latus (f. 24, 25).—This is the “crowned admiral” of collectors,
and although slightly more ventricose and shouldered, I have
great hesitation in admitting its separation from C. ammiralis.
31. princeres, Zinn.—C. solidus, turbinatus, irregulariter coro-
natus, aurantius, lineis undulatis longitudinalibus tenuibus vel
magnis ornatus (f. 31, 32, 33).—The shorter variety (f. 33)
with minute lines is C. Zineolatus of Valenciennes.
32. ruvitus, Menke.—C. tenuis, turbinatus, levis, roseus, mi-
nute coronatus (f. 323).—I should have expected the young of
C. princeps to present the appearance of this smooth, pink, turbi-
nated, lightly coronated and thin shell, but am assured by Mr.
Cuming that those collected by him are quite different.
33. Ruvrtiu, Leeve.—C. solidus, versus basin granulatim
striatus; spird obtusd, nodulis coronalibus obtusis ; ad spiram et in
medio albus, fusco maculatus, omnino lineis fuscis cinctus (f. 143).
—White at the top, and in a middle band speckled with brown ;
the other parts chestnut, encircled with dark lines, which from the
middle to the base are raised and granulated.
34. Tanerrensis, Brvg.—C. subpyriformis, fusco-purpurascens,
maculis albis vel czeruleis fluctuatis ad spiram et in medio ornatus,
omnino leviter striatus; spird obtuse coronati (f. 26).—This
purplish-brown shell is slightly striated, and is more pyriform
6 .
than C. Rattus, of which some collectors consider it a variety.
The latter is a more turbinated shell.
35. etapraror, Brod.—C. breviusculus, striatus, fuscus, flam-
mis longitudinalibus fuscis seu nigris flexuosis pictus, medio pal-
lid’ fasciatus; spird brevi, nodulis obtusis (f. 59, 60).—Distin-
guished by flexuous downward flashes of brown. It is finely
striated, and differs from C. drwnneus by being straighter at the
sides.
36. BrunNeus, M/awe.—C. subpyriformis, castaneus seu ful-
vus, fusco maculatus, versus basin striatus; spird plus minusve
elevatA, nodulis albis coronatd (f. 47, 48, 49).—Rather pyri-
form, brown, with a pale band, or white or fawn, with chestnut
bands or markings.
37. punctatus, Chemn.—C. solidus, striatus, fulvus seu gri-
seus medio et ad angulum albo fasciatus; punctis lineatim dispo-
sitis ornatus; variat flammis-longitudinalibus nigrescentibus ;
spira obtusi fusco maculata (f. 91, 92, 203).—The latter figure
probably represents C. pedlis-hyene of Chemnitz, a variety of
this.
38. primuta, Reeve.—C. subpyriformis, levigater versus basin
liratus, pallidé fulvus; spird obtusi, nodulis obtusis (f. 76).—
A nankeen-coloured shell, rather short, solid, obtuse and smooth,
with raised ridges near the narrow base.
39. pramenratus, Reeve.—C. subovali-conicus, obsoleté stri-
atus, albus, violaceo tinctus, maculis subviridibus bifasciatim dis-
positis; spira obtusi, apice roseo (f. 101).—A purplish-white
shell, prettily painted with touches of olive-green arrayed in two
bands.
40. Macrrtanicus, Brug.—C. turbinatus, parvus, solidus, pal-
lidus, fasciis duabus latis, maculis trigonis inspersis pictus (f. 77,
390).—In the variety represented by the latter figure the white
bands in the centre and on the angle are prettily marked with
reddish lines and spots. It is C. cidaris of Kiener.
41. macuirerus, Sowh.—C. brevis, solidus, turbinatus, ma-
culis junctis castaneis fasciatim dispositis (f. 74, 75).—More
turbinated at the top and narrowed at the base than C. Magedla-
nicus. The markings are more separated into patches and are
dark chestnut.
42. sPHACELATUS, Sowl.—C. C. maculifero similis, sed granu-
latim sulcatus, spird exserta (f. 105, 106).—This small shell re-
7
sembles C. maculiferus, but it is not so smooth, and the spire is
elevated.
43. cppo-NuLLI, Bruy.—C. solidus, turbinatus, levigatus seu
lineatim granulatus, fasciis latis castaneis seu aurantiis seu nigris
irregulariter fasciatim interruptis cinctus, maculis angulatis albis
et lineis interruptis ornatus ; spird elevaté, obtusé coronata (f. 64
to 68).—This celebrated species is remarkable for several varia-
tions in pattern and colouring, but the interrupted dotted dark
and white limes are constant.
_ 44. NeBuLosus, Solander.—C. laté turbinatus, C. cedo-nulli
similis sed superné latior (f. 61, 62).—Broader at the top and
less neatly coloured than C. cedo-nulli, and the dotted or granu-
lated lines are almost entirely wanting.
45. Leucostictus, Gmel.—C. C. cedo-nulli similis, sed valdé
angustatus, apice obtuso (f. 35, 36).—Like C. cedo-nulli, but
much narrower, with the angular patches of white broader.
46. varius, Zinn.—C. elongatus, lateribus paululim ventri-
cosis, granosus, albus seu luteus, maculis castaneis ornatus ; spira
elevata, nodulis moniliformibus coronaté (f. 40 to 42).—White,
granulated with patches of chestnut-colour,
47. invERRUPTUS, Mawe.—C. C. vario similis, sed leevior, late-
ribus rectiusculis (f. 43, 44).—Smoother and with straighter
sides than C. varius.
48. pLumBEUS, Reeve-—C. subpyriformis, lineis elevatis gra-
nulatis cinctus, ceeruleus, castaneo maculatus, versus basin purpu-
reus; spiri convexd, obtusé nodulifera (f. 131, 132).—Like C.
varius in form, leaden and purplish in colour, granulated, and in
the var. f. 131, named C. /iratus by Mr. Reeve, with elevated
ridges between the grains.
49. aLBomacuLatus, Sowd.—C. oblongus, minuté coronatus,
granulatus, aurantius, maculis albis magnis versus spiram et infra
medium ornatus (f. 113).—Straight-sided, granulated, orange-
coloured, with large white spots.
50. spectosissimus, Reeve-—C. oblongus, minuté coronatus,
lateribus rectis; roseus, rubro late interruptim fasciatus; fasciis
irregularibus (f. 123, 124).—Of a delicate rose-colour, with red,
irregular, jagged bands.
51. sprcrosus, Sowd.—C. breviusculus, turbinatus, minuté co-
ronatus, albo rufoque irregulariter fluctuatus, flammis rufis linea-
tim marginatis (f. 138)—More turbinated than C. speciosus,
8
with irregular jagged broad markings of reddish colour, bordered
by darker lines.
52. carprnais, Brug.—C. subpyriformis, obsoleté granulatus,
coccineus, in medio albo fasciatus; fascid fusco maculaté; spira
convexd, nodulis moniliferis coronaté (f. 117, 118).—Pyriform,
coronated with minute nodules, granulated, bright-red, with a
central white band, interrupted by brown markings.
b. Swelled near the upper angle and base.
53. puticarius, Brug.—C. ventricosus, obtusus, medio sub-
contractus, ad angulum et basin rotundatus ; albus, roseo pallidé
tinctus, punctis rotundis irregulariter pictus (f. 19, 20, 21).—
Solid, pinky-white, rounded at the base and at the angle of the
spire, with variously arranged black spots.
54, arenatus, Brug.—C. C. pulicario similis, sed punctis mi-
nutissimis fluctuatim dispositis (f. 17, 18).—The spots are like
grains of sand arranged zigzag fashion, otherwise this species is
like the last.
55. Vautiert, Kien.—C. C. pulicario similis, sed castaneo,
punctis quadratis (f. 23).—Like C. pulicarius, but of a chest-
nut colour, with the spots rather square.
56. Crytonicus, Chemn.—C. C. pulicario similis, sed nodulis
coronalibus obscuris, castaneo et albo variegatus, limeis punctatis
cinctus (f. 16, 22).—The nodules of the spire are almost want-
ing in the last whorl; the shell is variegated with fluctuating
patches of chestnut and dotted cross-lines. Fig. 16 is probably
a narrow variety.
ce. Obtusely coronated, generally ventricose, short.
57. Mus, Brag.—C. subovalis, striatus, griseus, flammis lon-
gitudinalibus fuscis; spird convexd nodulis albis coronati; in-
terstitiis migro-maculatis (f. 78).—Rather oval, striated, grey,
with brown longitudinal markings, and black spots between the
white nodules of the spire.
58. puncruratus, Brug.—C. brevis, subventricosus, griseus,
sulcatus, sulcis depresso-punctatis ; spiré acuta, ad angulum moni-
liferd, iter nodulos nigro-punctata (f. 104).—This little shell,
which resembles a short C. Mus, is encircled by punctured grooves.

tanter sulcatus; albus, coloribus variegatis flammis et fasciis in-
terruptis pictus; spira depressé ; anfractibus carinatis, valdé cana-
liferis (f. 519-522).—In the older and larger specimens the swell-
ing near the angle of the spire is more conspicuous; the whorls
of the spire are deeply hollowed, with a ridge at the angle.
342. Trmorensts, Brug.—C. elongatus, levis, pallidé roseus,
lineis albo rubroque tzeniatus, ad basin leviter liratus; spird
levi, anfractibus paululum excavatis (f. 517, 518).—A beautiful
shell, coloured something in the manner of C. auwrisiacus, but
much more delicately.
343. TERMINUS, Reeve.—C. quam C. gubernator magis eequali-
ter ventricosus, spire anfractibus haud tantum excavatis ; pallidé
purpureus, maculis magnis irregularibus sparsim pictus (f. 523 )
—Of a more oval form than C. gubernator; of a delicate violet-
colour, with large brown markings.
344. rULMEN, /teeve.—C. levis, oblongus, subventricosus, pal-
lidé purpureus, castaneo flammis irregularibus magnis sparsim
pictus ; spira convexa, obtusa, haud carinata (f. 351). = More short
and veutricose than the preceding. The spire not keeled.
345. srrtatus, Zinn.—C. oblongus, cylindricus, transversé
striatus, infra subquadratus ; pallidé violaceus, nebulosus, fasciis
interruptis et flammis longitudinalibus nigris aut fuscis pictus ;
spira subdepressa, maculata; anfractibus excavatis, carinatis ; va-
40
riat roseus, aurantio pictus, albo floccatus (f. 557; and delicate
rose-coloured var., see Hrontispiece, f. 558).—More cylindrical
and wider than C. gubernator, with the surface striated.
k. Cylindrical, inflated, sometimes coronated.
346. arocrapnus, Linn.—C. ventricosus, inflatus, levis, pal-
lidé roseus, ceruleo-nebulosus, lateribus rectiusculis; flammis
reticulatis castaneis pictus; spira lata, depress, ad angulum tu-
berculis magnis coronati; anfractibus paucis, latis (f. 560).—
The well-known map-coloured, large, coronated shell.
347. vutiea, Linn.—C. C. geographo similis, sed medio ven-
tricosus, spird angustiore vix coronata; lineis articulatis cinctus ;
flammis undatis (f. 551, 552).—The centre is ventricose, and
the spire narrower than in C. geographus, scarcely coronated ; it
is encircled with articulated lines.
348. inrermepius, Reeve—C. quam C. geographus magis
obliquus, angustior, medio inflatus; spird elevata, angusta, tuber-
culis mediocribus coronata (f. 549).—Marked in the manner of C.
geographus; itis more oblique, the spire narrower, more elevated,
and less largely coronated.
349. opscurus, Humph.—C. parvus, C. geographo similis, sed
angustior, spiré levigatai; czeruleus, castaneo fasciatim obscuré
nebulosus (f. 526).—It is small, narrow, obscurely coloured with
brown, and has a smooth spire.
350. cervus, Lamk.—C. oblongus, solidus, supra medium in-
flatus, levis, pallidé fulvus, maculis fuscis nebulosis seriatim va-
niegatus et tessellatus; aperturd alba; spird subdepressi, angu-
lata; anfractibus latis, planulatis (f.548).—Resembling C. dudlatus,
but with a more angular top, and more tapering below; the deli-
cate fawn-tint and tessellated markings further distinguish this
elegant and extremely rare species.
351. Buttatus, Linn.—C. solidus, ventricosus, levis, roseo et
aurantio nebulosus, fusco irregulariter variegatus; spird parva,
depressd ; anfractibus paucis, canaliferis (f. 550).—Beautifully
mottled with pink and orange, with a contracted spire.
352. Drsuaynsit, Reeve. —C. tenuis, inflatus, articulato-linea-
tus, infra sulcatus, supra angulatus, ubique fulvo-grisescente pal-
hide nebulosus (f. 546).—From its light fawn-colour, mistaken
by us formerly for the C. cervus.
4)
353. MELANCHOLICUs, Zamk.—C. oblongus, inflatus, infra sul-
catus, attenuatus, ubique tenuissimé striatus, aurantius, infra
medium maculis albis unifasciatus; spird alba, angulata (f. 547),—
This shell, evidently belonging to the same group with the pre-
ceding, is nevertheless of a very distinguished form.
l. Cylindrical, reticulated.
354, textitE, Jinmn.—C. cylindricus, subventricosus, lineis ru-
bris reticulatus, laté aurantio interruptim fasciatus; fasciis lineis
articulatis transversis et strigis longitudinalibus pictis; spira py-
ramidali, levigataé, maculis aurantiis et lineis rubris flexuosis or-
nata (f. 567).—The typical C. textile is a rather ventricose shell,
reticulated with reddish lines. Interrupted by white spots and
reticulated lines are orange bands of different widths; these bands
are marked with downward stripes and cross-lines. The follow-
ing shells, described by authors under different names, many of
which I think really belong to this species, are separated, princi-
pally on the ground of variations in the relative proportions in
the different parts of colouring above described, and partly on
variations of form; but the characters of the shells are very un-
certain, and the intentions of the authors still more so. Without
attempting to take in all the variations, I have endeavoured to
chose the best representative of each so-called species.
355. TIeRINUS, Sowb.—C. quam C. textile angustior, luteus,
strigis nigrescentibus magnis ; spird prominula (f. 568; var. 579).
—More slender than C. ¢extide, with a richness in the general
tint; markings rich and dark.
356. vicartus, Lamk.—C. quam C. textile magis conicus, la-
teribus medio contractis, maculis albis magnis (f. 565).—More
straight-sided than C. tertile, or even a little contracted in the
middle, more white and less orange in the colouring.
357. scriptus, Sows.—C. cylindricus, inflatus, albus, lineis te-
nuissimis angulatis scriptus (f. 563).—A very light cylindrical
shell, finely reticulated with very thin lines.
358. verRicuLum, Reeve.—C. quam C. textile brevior, magis
ventricosus, maculis albis majoribus, fasciis aurantiis disruptis
(f. 570).—Short and stout, with a larger proportion of white
than in C. textile.
359. Lecatus, Lamk.—C. solidus, roseus, angustus, subangu-
latus, tenuiter rubro reticulatus; aureo interruptim fasciatus et
VOL. III. G
42
longitudinaliter fusco strigatus (f. 566).—LKasily distinguished by
its solidity, its narrower form, and roseate hue.
360. canonicus, Brug.—C. solidus, ceruleus, angustus, mi-
nuté reticulatus, laté fusco-nigrescente fasciatus (f. 56$).—This
and the following species are more solid than C. teati/e, with
closer and darker markings. The varieties of each have been
much confounded; some distinguish them by the roseate hue in
the aperture of C. canonicus, but I believe M. Bruguiére meant
C. canonicus to be a narrow, straight-sided shell, aud C. archiepis-
copus a broader one; and he even remarks that there is a pink-
mouthed variety of the latter.
361. arcuriepiscopus, Brug.—C. solidus, ceruleus, ventricosus,
minute reticulatus, fusco-nigrescente fasciatus (f. 571, 572).—
See note on C. canonicus.
362. pannicutus, Lamk.—C. subturbinatus, spird obtusa,
minuté reticulatus, aurantio equaliter trifasciatus, fasciis nigro-
lineatis ; fauce purpured (f. 574.).—Distinguished from C. textile
and others by its more turbinated form and closer colouring. It
is purple within.
363. aBBas, Brug.—C. C. panniculo similis, sed fasciarum in-
terstitiis minuté et concinné reticulatis (f. 575).—The reticulated
lines are remarkably neat and lace-like between the bands, the
marks being rounded and equal.
364. See p. 47.
865. corpuLa, Sowb.—C. cylindricus, ventricosus, tenuiter
striatus, lineis fulvis minute reticulatus, lineis et maculis fusco-
aurantiis trifasciatus; spiri striatd, anfractibus subexcavatis
(f. 573).—Of the typical form of C. tertile, but finely striated
and more solid. The colouring is also different.
366. victort®, Reeve.—C. tenuis, subinflatus, tenuiter trans-
verse striatus, ceruleo nebulosus, fusco-rubescente reticulatus,
maculis magnis aurantiis fusco-virgatis marginatis seriatim pictus ;
spird producti, angulataé (f. 575, 576).—A light, rather angular
shell, distinguishable at a glance from all the preceding species of
the same group.
367. reLATUS, Reeve.—C. oblongus, subfusiformis, angulatus,
lateribus rectiusculis ; fulvo tenuiter angulatim reticulatus, macu-
lis magnis aurantiis, fusco-rubescente strigatus, laté bifasciatus ;
spird pyramidali, acuta; anfractibus depressiusculis (f. 584).—A
48
very rare shell, approaching C. gloria-maris rather than C. textile
in form, and in the light sandy character of its reticulation. It is
much shorter, however, and has two broad bands of orange patches.
368. GrortA-maRis, Chemn.—C. tenuis, elongato-fusiformis,
minutissimé fulvo reticulatus, maculis angustis rubro-strigatis
fasciatim ornatus; spiri elevatd, leviter gradaté (f. 586).—Hle-
gantly fusiform and delicately reticulated, this shell is not only
one of the rarest but also one of the most beautiful of Cones.
369. rETIFER, MJenke.—C. solidus, brevis, obtusus, roseus,
fasciis aurantiis longitudinalibus et transversis rubro-nigrescente
strigatis ornatus, interstitiis rubro reticulatis; spird pyramidal,
anfractu ultimo rotundato (f. 580).—A short, thick, solid shell,
richly coloured.
370. Luctpus, Jawe.—C. subcylindricus, solidus, obtusus, in-
fra sulcatus, transversé rubro lineatus, interstitiis longitudinaliter
divisis; maculis nigrescentibus et albis triseriatim ornatus; spira
obtus4, maculosd, et reticulatéi; anfractibus depressis, angulatis
(f. 581).—Distinguished by the regular red lines across the shell.
371. Mapacascariensis, Sows.—C. subventricosus, oblongus,
levis, lineis rubris minuté reticulatus; maculis magnis albo fusco-
que articulato-lineatis bifasciatim ornatus; spird brevi, angulata ;
anfractibus depressiusculis, apice acuto (f. 583).—The markings
resemble those of C. omaria, but it is a short shell, with sharp
apex.
372. pratatus, Brug.—C. oblongus, obtusus, levis, roseus,
ceruleo partim suffusus, ineequaliter reticulato-maculatus, macu-
lis albis uno latere subczeruleis ornatus; spird brevi, obtusa (f. 585).
The white and pink spots are shaded with blue.
373. Evizm, Kien.—C. solidus, subturbinatus, castaneus, ni-
gro alboque articulatim lineatus, maculis albis cordiformibus et
Ineis reticulatis fasciatim variegatus ; spird obtus4; anfractu ulti-
mo rotundato, convexo (f. 578).—In the specimen originally de-
scribed, the brown colour occupies a larger proportionate space
than in the specimen represented. Like C. episcopus and others,
the species has a very thick brown spire.
374. Cotusrinus, Lamk.—C. solidus, subcylindricus, castaneus,
maculis albis longitudinalibus irregulariter ornatus ; spiri obtusa,
angulo rotundato (f. 587).—Another obtusely spired solid shell,
marked with irregular oblong white spots, longitudinally arranged
on a dark-brown ground.
44
375. ruprainosus, Lamk.—C. C. Coluébrino similis, sed maculis
albis minoribus, numerosis, interstitiis articulato-lineatis (f. 590).
—Although the spots are smaller, and the interstices marked with
articulated lines, | doubt the propriety of separating this from the
preceding.
376. crocatus, Lamk.—C. oblongus, transverse leviter striatus,
supra convexus, medio subcontractus, infra subattenuatus ; auran-
tius, albo sparsim maculatus (f. 588, 589).—In one variety the
white is more plentiful, but the species is not difficult to identify.
377. pEeNNAcEUS, Lamk.—C. solidus, subcylindricus, albus vel
roseus, rubro reticulatus, maculis aurantiis rubro alboque articula-
tis pictus, prope angulum convexus, infra liratus ; spird brevi,
obtusa (f. 599-601).—The first is the typical form of this vari-
able species.
378. wptscorus, Lamk.—C. elongatus, cylindricus, maculis
magnis fluctuatis pictus; interstitiis laté reticulatis; spira brevi,
obtusissima (f. 596-598).—More lengthened and cylindrical than
C. pennaceus, with large, fluctuating, dark, reddish-brown patches,
which are not marked with articulated lines, and the interstices
reticulated with large meshes.
379. omarta, Brug.—C. elongatus, cylindricus, tenuiter stria-
tus, lineis rubescentibus minute reticulatus, maculis magmis arti-
culato-lineatis latis fuscis bifasciatus ; spiri brevi ; apice subacuto,
roseo (f. 594, 595).—The markings are finer than in C. penna-
ceus, the shape more lengthened and cylindrical.
380. convoLutus, Sowb.—C. quam C. omaria magis angusta-
tus; spiri elevaté, acuminat&i; roseus, minute et tenuiter roseus,
fauce pallidé aurantius (f. 564).—This very distinct species has
an affinity with C. omaria, but it has an elevated sharp spire, and
is narrower, the whorls being as it were more closely rolled up.
I venture to draw from Mr. Cuming’s specimen, and colour from
that of Mrs. Deburgh.
381. avuxicus, Linn.—C. cylindricus, subventricosus, leviter
striatus, albus, areis magnis castaneis irregulariter angulatis pictus ;
interstitiis angulatim lineatis; spiré pyramidali (f. 593).
382. auratus, Lamk:.—C. C. cylindrico similis, sed angustior,
aureo aut roseo tinctus ; maculis plus minusve punctisa lbis linea-
tis (f. 591).—Of a more narrowed cylindrical form than C. audi-
cus, with rows of small white specks on the brown marks. The
golden-tinted var. (not figured) is the most common.
45
383. maoniricus, Reeve.—C. C. aurato similis, sed brevior,
magis solidus, supra magis convexus; spird obtusd (f. 592).—
Shorter, thicker, and more convex at the upper part of the body-
whorl than C. auratus, of which it is perhaps a variety.
384. aungus, Brug.—C. oblongus, angustus, cylindricus, trans-
versé striatus, fasciis longitudinalibus magnis aurantiis lineis ru-
bris nigrescentibus strigatis pictus, interstitiis tenuiter reticulatus ;
spird pyramidal, acuta (f. 555).—Striated, narrower than C. au-
ratus, with downward bands of colour reticulated between.
385. cLavus, Zinn.—C. C. aureo similis, sed crebré reticulatus,
fasciis latis fuscis pictus (f. 561).—Like C. aureus, but with close
reticulations and cross-bands of brown.
386. crrcumctsus, Born.—C. oblongus, angustatus, cylindri-
cus, transversé striatus, pallidé purpureus, fusco plus minusve ma-
culatus et fasciatus, lineis albis sparsim punctatis cinctus (f. 562,
and Frontispiece).—Characterized by narrow white bands, which
are spotted at intervals.
m. Narrow, cylindrical ; spire rounded with close, perpendicular
whorls.
387. nussaTeLLa, Zinn.—C. angustatus, cylindricus, striatus,
lineatim punctatus, fusco seu aurantio maculatus et fasciatus
(f. 553, 554).—I feel almost tempted to distinguish the latter as
a species.
388. TENELLUS, Chemn.—C. quam C. nussatel/a magis angu-
latus, lateribus rectiusculis ; spird brevi, obtusi; anfractibus pau-
lulum undulatis ; striis minuté punctatis (f. 566).—Straighter than
C. nussatella, with the upper part of the whorl more angular, and
the spire short and obtuse ; the sculpture and colouring are finer.
Tt has been thrice named,
389. pacryLosus, Kier.—C. elongato-cylindricus, levis, auran-
tius, maculis parvis trigonis albis sparsim ornatus ; spira prominula,
lateribus convexis, apice acuto, anfractu ultimo angulato (f. 536).
—A very characteristic species.
390. viotacrus, Reeve.—C. elongato-cylindricus, levis, viola-
ceus, fusco maculatus et fasciatus; spird producti, lateribus con-
vexis, apice acuto (f. 537).—A beautiful violet-coloured smooth
shell.
391. coccrnnus, Gmel.—C. cylindricus, subventricosus, antice
subattenuatus; striatus, coccineus seu fuscus, medio fascid alba
46
nigro-maculati cinctus ; spird obtusa, subtuberculata (f, 538, 539).
—Rather ventricose in the middle, and tapering near the base ; dis-
tinguished by the beautiful colour, and the white band in the centre
bordered by black markings.
892. eranuLatus, Linn.—C. subcylindricus, angustus, trans-
verse liratus ; liris subgranulosis, infra duplicatis ; coccineus, medio
fascia albé fusco-maculatai cinctus; spird alba, fusco maculata ;
anfractibus rotundatis, gradatis (f. 540, var. 541).—Hncircled
by granulated ridges, and quite unlike any other species. The
white variety (C. verulosus, Kien.) is figured from Miss Saul’s
specimen.
393. cyLinpRraceus, Brod.—C. cylindricus, angustus, levis,
aurantius vel fuscus, strigis interruptis fluctuatis longitudinalibus
ornatus ; spira elongati, obtus4; anfractibus rectis (f. 527, 528).
—In this species the spire is drawn out, so as to reach a third of
the entire length.
394. TEREBELLUM, Mart.—C. elongatus, cylindricus, solidus,
ineequaliter liratus, supra convexus, infra subattenuatus, pallidus,
fulvo pallidé fasciatus, exruleo tinctus; spird valdé convex4 (f.
559).—Transversely ridged, swelled near the angle of the spire,
which is very convex.
395. cians, Brug.—C. cylindricus, granoso-liratus, purpureo
tinctus, fusco vel purpureo-fuscescente late fasciatus ; spird convexd,
crenulata (f. 530, 531).—Both varieties have the strie granulated
and the spire crenulated.
396. TENUISTRIATUS, Sowb.—C. C. glandi similis, sed tenuissimé
striatus ; striis vix granulatis; spira levi (f. 532, 533).—The strice
are much finer than in C. glans, and scarcely granulated; spire
smooth.
397. renpINEeNS, Brug.—C. solidus, cylindricus, liratus, albus,
fusco-violascente trifasciatus, longitudinaliter strigatus; infra
truncatus; spiri elevati, obtusi (f. 534).—A very solid shell,
banded in both directions with dark-brown, and obtusely trun-
cated at the base.
398. scaBRiuscuLus, Chemn.—C. brevis, obtusus, subturbina-
tus, granoso-liratus, fuscus, maculis et fascid albis seu albus fusco-
maculatus; spird obtusd (f. 542, 543).—Although of a short and
obtusely conical form, this species has an affinity with C. glans.
399. NucLEUS, Reeve.—C. cylindricus, levis, fuscus, infra me-
dium maculis irregularibus albis fasciatus; spird convex’, apice
? >
47
minuto (f. 529).—A small, smooth, brown shell, with a band of
irregular white spots below the centre.

luteus seu coccineus, maculis fuscis longitudinalibus albo-mar-
ginatis fasciatim pictus (f. 544, 545).—Both varieties are graceful
shells, with rows of white, bordered, linear, brown markings.
401. arramentosus, Reeve.—C. minutus, striatus, obtusus,
nigrescens, maculis albis sparsim ornatus ; spird obtusa (f. 317).
—A curious little dark-coloured shell, with a few white spots on
the upper part of the whorls.
402. urerocLypHicus, Duclos.—C. brevis, liratus, sub-turbi-
natus, obtusus, fuscus, maculis albis irregularibus fasciatim or-
natus ; spird alba, maculata ; anfractibus rotundatis (f. 318, 319).
—This small shell has an affinity with C. scabriusculus, from
which however it differs in the white, hieroglyphic markings.
403. mirratus, Brug.—C. oblongus, granulato-liratus, luteus,
castaneo fasciatim maculatus; spird convexa, elevata (f. 535).—
There is no danger of confounding this species with any other.
(The following species were accidentally omitted from their places. ]
'345*. rLoripus, Sows.—C. C. striato similis, sed vix striatus,
lateribus magis ventricosis, spird magis angustata, anfractibus haud
tantum excavatis ; rosaceus, floccis albis et maculis fuscis sparsim
variegatus (f. 558, Frontispiece).—Besides the smooth surface and
delicate colouring of this shell, it is distinguished from C. striatus
by its less cylindrical form and the comparative narrowness of the
spire, which is also less deeply grooved.
364. pyramipaLis, Jamk.—C. angustus, solidus ; spird promi-
nula, strigis longitudinalibus undatis (f. 579).—Narrow, solid,
with a rather produced spire. The brown markings fall in wavy,

MONOGRAPH OF THE GENUS
ANCILLARIA, Lamb.
Char. Gen. Testa polita, ovata vel oblonga, ad basin balteo in-
crassato marginata; supra balteum suturd nonnunquam celata,
plerumque ad terminum dentiferd cincta; spird pyramidali, su-
turd tegmine calloso, polito celaté; columella varice calloso,
plerumque striato, ad basin terminante; apertura magna, anticé
effusi, plerumque unidentata, ad basin emarginatd; operculo
corneo, concentrico, subovali.
Although Lamarck first published this genus under the name
of “ Ancitua,” I cannot admit the justice or convenience of re-
fusing to adopt the alteration which he subsequently made. That
alteration appeared in all his more matured works, and has been
almost universally adopted. The species have increased in num-
ber from four described in the ‘ Animaux sans Vertébres,’ to
forty-four contained in the present monograph. This includes
“ Buccinum glabratum” of Linneus, which is unfortunately
placed at the head of Lamarck’s genus “ Hburna,’ but which
has no connection with the other species enumerated under that
title. It is admitted here, with two allied species, by general
consent, the most advanced of modern conchologists making
only a subgenus of the group. The Ancillarie are polished,
olive-shaped shells, with the spiral suture covered by a coating of
enamel, having an oblique, thickened belt at the base, which is
sometimes double ; above this belt is a suture, generally ending
in a tooth near the base of the outer lip, but which is some-
times covered and hidden by enamel, and a tortuous triangular
varix at the lower part of the columella. The operculum is
horny, oval, and concentric. The species may be thus arranged :
—Section I., Sp. 1 to 21, in which the spire-covering enamel
is continued downwards as far as, and sometimes over, the basal
suture. Section IL., Sp. 22 to 41, in which the said enamel

ceases at various distances above that suture, in most cases form-
ing a marginal band on the upper part of the last whorl. Sec-
tion THES Sp. 42 to 44, A. glabrata and its two allied species,
which, agreeing with the last group as to the enamel, present. the
pauitianal characters of a divided varix, and an oblique umbilicus
between the body-whorl and the columellar callus.
Subg. Dipsaceus, Klein.
Sect. I. Spire-covering enamel extended over the body-whort.
1. torosa, Meusch.—Mauritiana, Sowb. Sp. Con.—A. subcy-
lindrica, longitudinaliter striata, castanea, seu pallide fulva, seu
alba; spird brevi; anfractibus subquadratis, balteo inferiori sim-
plice ; aperturdé magnd, ad basin lati, vix emarginati; varice
albo, leviter striato, elongato (f. 30, 31, 32)—This now well-
known species is remarkable for the width and length of the
aperture in proportion to its very short spire. The three varie-
ties are common in collections.
2. aperta, Sowd. Sp. Con.—A. subcylindrica, levis, aurantio-
rubra; spird brevissim&; anfractibus rotundis, balteo inferiori
simplice ; apertura magna, ad basin vix emarginata; varice albo,
leviter striato, elongato (f. 27, 28).—This species, which differs
from A. Mauritiana in being smooth and having rounded whorls,
is very rare. [ am indebted to the kindness of Mrs. De Burgh
for the use of the beautiful specimen figured.
3. scapHELLA, Sows. Th.—A. cylindrica, alba; spira brevi ;
aperturi magna, ad basin vix emarginatd; varice levi, elongato,
balteo inferiori vix distincto; suturd inferiori elevatd (f. 37, 38).
—Resembling the two preceding in form, but more cylindrical,
white, and smooth. The basal suture, which is obsolete in
Sp. 1 and 2, is here distinct, giving an angularity to the lines of
growth, and ending in a scarcely perceptible projection. Unique
as far as known.
4, cytinprica, Sow). Th.—A. cylindrica, parva, alba, 4. sca-
phelle similis, sed magis augustata et recta (f. 18, 19).—A small
white shell, more cylindrical, straight, and narrow than A. sca-
phella. Unique as far as known.
5. Tronsoni, Sows. Th.— A. subovalis, politissima, alba ;
spird brevi; apertura elongata; suturd inferior subcallosa, balteo
inferiori simplice ; varice brevi, striato, canali post varicem posi-
to (f. 20, 21).—Having something of the form of A. scaphella,
ANCILLARIA. 3. 59
yet approaching 4. ampla, with a much shorter varix than either.
Unique as far as known.
6. ampta, Gmel.—candida, Lamk.—A. elongata, alba seu
pallidé cinnamomea; spird acuminati; apertura ad basin lata,
effusi; suturd inferiori dentifer’, balteo inferiori simplice ; varice
elongato, obliqué striato (f. 26, 29).—With a more produced
spire than either of the preceding, but with the aperture wide at
the base. Both varieties common.
7. atBisuLcata, Sowd. Sp.—Caffra, Horsch. ?—A. oblonga,
cinnamomea, ad spiram lineis albis cincta; spiri brevi, etate
yaldé calloso-rotundataé ; suturdi inferiori dentiferd, albo margina-
ti, balteo imferiori simplice; varice tortuoso, sulcato (f. 39, 40,
41).—The spire is sometimes rendered obtuse and rounded by a
thick deposit of enamel. The spiral and basal sutures are white.
Common.
8. crinnamomeEa, Lamk.—A. oblonga, castanea seu pallidé cin-
namomea, supra albo-fasciati; spiri subproductd, ad suturam
rufo-cincté ; aperturé oblonga, infra unidentata, effusi, ad basin
emarginaté ; suturd inferior’ alb&; varice columellari tortuoso,
crasso, striato, fulvo (f. 33, 34, 35).—This shell, to which Mr.
Swainson applied the name A. effusa, and which is figured under
that name in the ‘Species Conchyliorum,’ seems to me to agree
perfectly well with Lamarck’s description of cinnamomea, the
brown varix mentioned by Lamarck not beimg found in the shells
figured for 4. cinnamomea in the “ Species.”
9, atBorascrata, Swains.—A. oblonga, ventricosa, A. cinna-
mome@ similis sed fulvo-aurantia, magis ventricosa; varice albo (f.
36).—The A. cinnamomea is more straight-sided than this species,
which is of a light orange-colour, and has a white varix. It is
not without hesitation, however, that I admit the specific value of
these distinctions.
10. acuminata, Sows. Th.—A. elongata, cimmamomea seu alba,
intis pallide fulva ; spira exserté, acuminata ; suturd callos4; ulti-
mo anfractu subangulato; suturd inferior’ alba, balteo inferiori
simplice, castaneo; varice crasso, tortuoso, striato ; aperturd ob-
longa, infra unidentat!i (f. 66, 67).—An angle in the last. whorl
gives a pyramidal form to the spire, which is also characterized
by a slight rising round the whorls at the suture. The sides of
the shell are rather straight. In other respects it is like the
more acuminated specimens of A. albisulcata.
60 ANCILLARIA. 4.
11. Desnayrsu, 4. Adams ?— A. elongata, sub-ventricosa,
pallidé cinnamomea ; spira exserta, acuminata ; anfractibus rotun-
datis ; varice albo, levi, brevi; apertura oblonga, anticé leviter
unidentata (f. 68, 69).—Of a uniform pale cinnamon-colour, re-
sembling Sp. 10, but with more produced spire, rounded whorls,
and depressed suture. It is also less straight-sided. I find the
species named as above in Mr. Cuming’s collection, probably by
Mr. A. Adams.
12. tivgoxata, A. Adams.—A. parva, oblonga, pallidé fulva,
longitudinaliter lineata, ad suturas albo-cincta; apertura elonga-
ta, anticé unidentatd ; varice columellari parvo, striato (f. 22, 23).
—It is like a miniature representation of A. albisulcata, but be-
sides being a thin shell with more produced spire, it has a very
small narrow columellar varix.
13. srriotata, Sows. Th.—A. parva, A. lineolate similis, sed
magis ventricosa ; spird breviusculd ; test& minute lineata ; varice
parvo (f. 24, 25).—This species might be a dwarf, pale, and line-
ated variety of A. albisulcata, but for the smallness of its varix.
It is more obtuse, solid, and ventricose than A. dineolata. The
fine longitudinal lines are not always visible.
14. casranna, Sowd, Sp.—aA. solida, ventricosa, castanea, alba
seu pallidé rosea, intis fulva; spird pyramidali, mediocri; aper-
turi ampla, anticé unidentatd; varice columellari albo, polito,
leviter sulcato ; balteo inferiori simplice (f. 76 to 79).—Mr. Swain-
son considered this shell as representing Lamarck’s A. ventricosa,
but the author of ‘Species Conchyliorum’ points out that no
tooth in the outer lip is mentioned in the description of that spe-
cies, while it is a distinguishing character in this. Our varieties
(f. 77, 78) are so much more angular in general form than the
others, that I felt almost inclined to separate them.
15. crassa, Sowb. Th.—A. aurantia, seu albido, A. castanee
similis, sed crassa; apertura breviori, area inter balteum inferi-
orem et suturam dentiferam angustiori (f. 86, 90, 91).—Best
described by comparison with 4. castanea; it is thicker and
smaller, with shorter aperture. The area between the basal groove
and the basal belt is very narrow.
16. ovatis, Sows. Th.—A. ovalis, alba, ventricosa; spird pro-
duct ; apertura breviusculf, anticé unidentata ; varice columellari
parvo, sulcato, balteo inferiori indistincto (f. 82, 83).—A small,
white, ventricose shell, resembling A. castanea, but with much
shorter mouth and very small varix, the basal belt indistinct.
ANCILLARIA. 5. 61
17. EpurNEA? Desh.—A. parva, pallida; spiri acuminata, py-
ramidali; apertura anticé unidentatd; varice columellari minuto,
canali valido post varicem posito (f. 84, 85).—It is like the more
angular form of A. castanea, but the colour and small size of the
full-grown shell, with the extreme smallness of the varix, will
sufficiently distinguish it. I am not certain of the identity of this
species with the one so named by Deshayes, but it is partly cor-
roborated by a little callus which is observable at the angle of the
aperture.
18. ventricosa, Lamk.—A. ovalis, ventricosa, politissima,
castanea, seu aurantia, seu rubro fasciata ; spiri acuminata, sub-
producté; sutura inferiori celati, balteo inferiori simplice ; aper-
turd subovali, edentula ; varice albo, polito, sulcato (f. 87, 88, 59).
—This species resembles the more oval form of A. castanea, the
difference being that the basal groove is covered by the enamel,
and becomes obsolete at the margin of the aperture, so that there
is no tooth. One of the commonest species,
19. Futva, Swains.—A crassa, ovali, infra lata, fulva seu alba,
seu fasciis pallidis roseis albis et fulvis variegata ; sutura inferiori
celaté; apertura infra effusd, edentuld; varice crasso, sulcato (f.
72 to 75).—Much more thickened and oblique than 4. ventri-
cosa, with the lower part peculiarly widened and the aperture sub-
trigonal. Rather common.
20. varteGaTa, Swains.—A. latior quam A. ventricosa, magis
cylindrica et solida, pallidé fulva, fasciis albis et roseis variegata
(f. 70, 71).—This species and the preceding are admitted as va-
rieties of A. ventricosa in the ‘Species Conchyliorum;’ but I think
the broad base of 4. fu/va, and the wider and more cylindrical
form of A. variegata, being constant characters, are sufficient to
distinguish them.
21. exiaua, Sowd. Sp.—A. parva, alba seu pallidé fulva, ovalis ;
spira producta, acuté; apertura parva, edentula, infra effusd ; co-
lumella varice parvo, trigono, striato et prope angulum aperture
callo acuté producto; suturad inferiori celata (f. 80, 81).—This
pretty little species is remarkable for a notch in the columella,
produced by the projection of an angular callosity, which is not
observed in any other species.
Sect. Il. Spire-covering enamel not reaching the basal suture.
22. TankeRvILu, Swains.—A. ovali-elongata, aurantio-flavida ;
62 ANCILLARIA. 6.
spird producti; anfractibus supri rotundis, sutura varice spirali
tecta, tegmine calloso versus suturam fnieecen extenso, suturam
gradatim appropinquante, balteo inferiori medio diviso ; varice co-
Jumellari trigono, oblique uni-suleato ; apertura subovali, infra
validé emarginati, labio externo unidentifero (f. 4, 5). "—'The
texture and colour of this species resembles that of the beautiful
A. glabrata. 'The spire-covering enamel reaches over two-thirds
of the body-whorl in front, whence it gradually widens and de-
scends very near the inferior suture, towards the outer margin,
so that the uncovered bell becomes narrower as the shell grows
older.
23. pimrprata, Sows. Th.—A. tenuis, elongata, alba, fulvo
supra suturam tincta; spird elevati; anfractibus subrotundis ;
tegmine calloso, ad medium anfractu ultimo producto, balteo in-
feriori duplicato, labio externo unidentato ; varice elongato, an-
gustato, sulcato (f. 55, 56).—This thin, pale species presents a
medium in respect of the extension of the spire-covering enamel,
which reaches nearly halfway down on the body-whorl. The two
specimens in Mr. Cuming’s collection are the only ones I have
seen.
24. BLoNGATA, Gray.—A. tenuis, elongata, alba, tenuissimé
cancellata ; anfractibus tegmine spirali late marginatis ; ; spira elon-
gata, gradata, spiraliter rata; suturd inferiori pené oblita, balteo
inferior] medio divisi; varice columellari lneari; aperturd ampla,
basi emarginata, labio externo vix unidentato (f. 52, 53).—This
thin, white, elongated shell has the spiral enamel forming a broad
band over the upper part of the whorls. The uncovered surface is
finely striated in both directions.
25. cinauLaTa.—A. tenuis, ovalis, supra purpurea, infra fulva;
fascié fuscd ; spird elongati, obtusd; anfractibus ventricosis, balteo
albo angusto marginatis, lined elevaté supra suturam cinctis; bal-
teo inferior! supra fusco, infra albo, medio lined elevati diviso ;
varice columellari tortuoso; apertura ampla, infra validé emarginata.
—In this elegant species there is no trace of the basal tooth-
bearing groove. A specimen has lately come into the possession
of M. Vernéde which is twice the size of our figure, so that, with
the splendid “ Vernede?,” that gentleman has the two largest An-
cillari@ in existence.
26. oprusa, Swaims.—A. ovata; spird brevi, obtusa, crassa
obtect’; ultimo anfractu tegmine spirali marginato; infra lined
impress, alba, balteo inferiori duplicato, varice columellari trigono,
albo, unisuleato ; aperturi ovali, mfr’ emarginatd; labio externo
ANCILLARIA. 7. 63
infra uniplicato (f. 15, 16).—The spire is thickened and rendered
obtuse by a thick coating of enamel, ending in a narrow belt over
the last whorl.
27. austraLts, Sowb.—A. oblonga, solida, fusca seu plumbea ;
spira pyramidali, obtecta, albo et fulvo spiraliter fasciata ; tegmine
incrassato super ¢ ‘anfractum ultimum albo- marginato ; sutura infe-
riori distineta ; balteo inferiori crasso triplicato, supra fusco, infra
albescente; aperturd subovali, emarginati, labio externo uniden-
tato; varice columellari sulcato, ad tegmen crassum laté super an-
fractum ultimum depositum juncto (f. 1, 2).—Over the dark-
brown colour of the body-whorl there is a leaden whiteness almost
peculiar to the species. The columellar side of the mouth has a
thickened callus, which spreads over part of the whorl and spine.
28. pupressa, Sowd. Th.—A. A. australi simili, sed spird magis
depress’, tegmine calloso valdé incrassato (f. 3).—The spire 1s
shorter than in A. australis, and the thickened callus of the co-
lumella and spire gives greater width to the top. I am neverthe-
less doubtful whether it is right to separate the species.
29. TRIcoLoR, Gray.—A. minuta, ovalis, acuta, A. australi
similis, sed magis angusta, tenuior ; spird vix obtecta (f. 9, 10).—
These pretty little shells may possibly be the young of A. australis.
In specimens of that species which are not much thickened by
callus, we observe the reddish-brown and white bands on the
spire, which are so conspicuous in A. tricolor.
30. mucronata, Sow). Sp.—A. ovali-oblonga, pallidé brun-
nea; spiri tegmine fulvo incrassaté, apice mucronata, ultimo an-
fractu supra tegmine marginato, infra balteis duobus cincto ; balteo
superiori medio cortato, inferiore albo; varice columellari trigono,
albo, sulcato; aperturaé unidentatd (f. 11, 12, 14).—A species
whose characters place it halfway between 4. australis and A. ru-
biginosa. The spire is thickened with callus, but has a small point
at the apex.
31. ANGUSTATA, Sowb. Th.—A. A. mucronate similis, sed parva,
angustata; spird obtus4 (f. 13).—Had this been an Australian in-
stead of a Chinese shell, I should have considered the absence of
a pointed apex, and the greater narrowness of the figure, as mere
accidental variations in the preceding species.
32. VeERNEDEL, Sows. Th.—A. fusiformis, ventricosa, aurantio-
fulva; spird elongata, acuminata, gradati; anfractibus balteo
calloso aurantio marginatis, infra sulcum inferiorem fascid alba ;
balteis inferioribus duobus, uno aurantio in medio plicato, altero

albo ; aperturi ampla, supra rosed, infra alba, unidentata, emar-
ginat’; varice columellari obliqué trigono, ad basin truncato, su-
perné unisulcato (f. 7).—This Queen of Ancillaria is nearly twice
as long as any other species. Two specimens of it have been
many years in the possession of H. Vernéde, Esq., who originally
received them as Chinese shells. The nearest resemblance in
form and structure is 4. rubiginosa, which, although a large An-
cillaria, is small, compared to these giants. 4. Vernedei is much
lighter. It is of an orange-yellow colour, instead of brown ; it
has no columellar callus, and is not thickened at the spire; its
varix is thin, and comparatively smooth and flat.
33. ruBIGINosA, Swain.—A. fusiformis, solida, subventricosa,
fusco-rubiginosa; spird oblonga, obtusi, tegmine calloso obtecta,
incrassatd, anfractibus balteo aurantio-fulvo marginatis, infra su-
turam inferiorem balteo medio plicato, et infra balteo simplice ;
columella callosi, supri incrassati et expansi; varice crasso,
albo, unisuleato; apertura unidentata (f. 6).—A solid, fusiform,
reddish-brown shell, with marginated whorls and thickened spire.
From China; very rare.
34. mami“tata, Hinds—A. A. rubiginose similis, sed an-
fractu ultimo magis ventricoso, callo spire et columell albo-
roseo; varice quadriplicato; spird spiraliter lirata (f. 8).—The
columellar callus and that which covers the spire is of a pale pink
colour and waxy appearance. ‘The last whorl is more prominent
at the shoulder than in A. rudiginosa, and the varix has several
distinct ridges.
35. srurtis, Sows. Th.—A. ovato-oblonga, alba; spira et co-
lumella callosis, fusco tinctis; spird producté; anfractu ultimo
marginato, infra suturam inferiorem balteis tribus, quorum medio
acuté elevato; apertura elongata, supra angulata, infra uniden-
tata, basi emaginata; varice angusto, obliqué triplicato (f. 17).—
In A. rubiginosa the aperture is very little longer than the spire ;
in this it occupies two-thirds of the length. The lower part of
the body-whorl has three belts, the middle one being elevated
into a sharp ridge at the back. The shape of the aperture is
different, being angulated above ; I cannot, therefore, admit this
as a variety of the preceding species.
36. marcinata, Lamk.—A. ovalis, pallida; spira pyramidali,
spiraliter liraté; anfractibus ventricosis, balteo seu albo, seu
fusco variegato, marginatis; ultimo anfractu infra suturam 1n-
feriorem balteis duobus crassis; varice rotundato, brevi, oblique
ANCILLARIA. 9, 65
quadriplicata; labio externo uniplicato, infrd profundé emarginato
(f. 46, 47).—Of an oval form, with a distinct band on the whorls,
typically variegated, but sometimes white. On each whorl of the
spire are several ridges. The spire and mouth nearly equal in
length.
37. Stnensis, Sowb. Th.—A. alba, parva, A. marginate si-
milis, sed magis angustata, varice angustiori et magis obliqua (f.
50, 51).—A small white shell, resembling 4. marginata, but
much narrower, and with the varix narrower and more obliquely
plicated.
38. oBLONGA, Sowb. Sp.—A. ovalis, elongata, A. marginate
similis, sed anfractibus rectiusculis; ultimo anfractu et balteis
inferioribus variegatis ; varice parvo, triangulari; spird levigata,
pyramidali (f. 42, 43).—The shape is narrower, the aperture
wider at the base, the spire more pyramidal, and the varix much
smaller than in 4. marginata, and besides, it has no ribs on the
spire. If, as I suppose, this is the true A. oblonga of the Sp.
Conch., it is more distinct from A. marginata than the fol-
lowing.
39. tineatTA, Kien.—A. A. marginate similis, sed magis elon-
gata; spird pyramidali, levigati; anfractu ultimo lineatim va-
riegato ; varice parvo (f. 57, 58).—More like 4. marginata than
the preceding, but much narrower, with a smaller varix, and
without the spiral ridges. It ditlers from 4. oblonga in not
having the aperture so wide at the base.
40. Nova-Zeranpi1a, Sow). Th.—A. parva, alba, A. marginate
similis, sed magis angusta ; spird levigatd, pyramidali; apertura
brevi (f. 48, 49).—Like 4. ineata and A. oblonga, it differs
from A. marginata in having no ridges on the spire; from A.
lineata, which it otherwise most nearly resembles, in the short-
ness of the aperture.
41. opnsa, Sowd. Th.—A. ovalis, ventricosa, pallida, fusco va-
riegata, medio fusco unifasciata; spird brevi, pyramidali; anfrac-
tibus marginatis; apertura magna, unidentati; varice parvo,
albo (f. 44, 45).—More obese than A. oblonga, with a shorter
spire. The middle of the body-whorl has a broad brown band,
above and below which are rows of brown spots; the margination
is also variegated.

42. auasrava, Linn. (Buccinum).—A. fusiformis, polita, au-
rantio-flavida; spira acuminata; anfractibus gradatis; tegmine
calloso tenuiter prope suturam inferiorem extenso, infra suturam
fascid impressi alba; balteis inferioribus duobus, planis, subs-

ultimum expansi, medio profundé et oblique umbilicata, infra ob-
liqué costa elongata, post varicem posita; varice trigono, sub-
planato ; apertura infra laté emarginata, unidentata (f. 62, 63).—
In this beautiful, although now common shell, the spiral enamel
is spread downwards to within a line’s breath of the lower suture.
A white dwarf variety is not uncommon.
43. BauTEaTA, Swains.—A. ovalis, alba seu aurantia; spird
obtusi, callo incrassati; anfractibus paucis, supra angulatim va-
ricosis; tegmine spirali infra medium extenso; balteis inferioribus
crassis, vix distinctis ; costA post varicem brevi; umbilico parvo,
haud profundo (f. 59-61).—A sort of rib or shoulder gives an-
gularity to the whorls of this species ; and the enamel does not
descend so near to the suture as in A. glabrata. The species is
distinguished by Mr. Swainson, and in the ‘Species Conchyliorum,’
principally by the narrowness and want of depth in the umbi-
licus. In the younger specimen it is wanting altogether ; and
my own impression is that the umbilicus increases in depth with
the age of the individual,
44. nivpa, Swains.—A. ovalis, alba seu aurantia; spird ob-
tusi, callo incrassatd ; anfractibus paucis, supra angulatim varico-
sis; tegmine spirali infra medium extenso, gradatim expanso ;
balteis inferioribus crassis, vix distinctis; cost& post varicem
brevi; umbilico magno, profundo (f. 64, 65).-—The band left un-
covered by the descending enamel becomes narrower towards the
outer margin. The umbilicus is deep.

Authors having generally agreed to remove from this genus
the Buccinum glabratum of Linneeus, which is an Ancil/aria, and
the Monoceros plumbewm of Chemnitz, and Hburna australis of
Sowerby, which belong to Psewdoliva, the remaining species form
a very compact and well-defined genus.

sulco ad terminum vix dentifero incisa; apertura ovali, posticé

operculum corneum, nucleo laterali.
The following species present a pretty natural group of Buc-
cinoid shells, which have a groove encircling the lower part of the
whorls, and generally terminating at the edge of the outer lip in
a sort of obtuse tooth. A canal is formed at the upper angle of
the aperture by the swelling of the outer lip, and a kind of callus
on the columella, and the anterior part of the aperture is, in
nearly all the species, deeply notched. The columellar lip is
thickened over the body-whorl. Operculum horny, with lateral
nucleus.

known smooth oval shell was placed by my late father in the genus
Hburna, with which it has some affinity, but the groove at the
lower part of the last whorl will distinguish it, and the genus
Eburna is better without it.

the general similarity in form, and the deep fosse of the suture,
M. Deshayes conjectures that this species is identical with Can-
cellaria spirata of Lamarck, and accuses me of having figured
the same shell in two characters, putting columellar folds when t
wanted it for a Cancellaria, and leaving them out for the Lburna.
It is impossible that M. Deshayes can have seen the two shells,
which are generically and specifically quite distinct.

and a stronger one on the inner lip. Of a dull grey colour
generally ; the shell is ornamented by a deep chestnut-brown
margin to the columella, and a tint of the same colour in the

They have not regular plicee on the columella as in Warginella,
although the columellar lip is slightly thickened and crenated ; the
outer lip is inflected, thickened, and crenated.

MONOGRAPH OF THE GENUS

‘Hindsia, Adams.
Char. Gen. Testa fusiformis, acuminata, longitudinaliter costa-
ta et spiraliter suleata; apertura subrotunda, in canalem elonga-
tum dorso elevatum terminante; labio interno tenui, integro,

Operculum corneum, ovaté unguiforme, margine integro.
Mr. Adams, in describmg this genus under the name of
Hindsia, has the following observations :—“ This genus partakes
of the characters of several recognized forms. Its animal, how-
ever, differs from that of Triton in the approximated tentacles,
with the eyes near their end, and the anteriorly produced foot ;
from that of Nassa in the tail not being bifurcated; and from
Phos in the absence of the long, single caudal filament. In its
shell it may be known from Phos by its recurved canal; from
Nassa by its circumscribed inner lip and elongated canal; and
from Zriton from its want of regular varices.”

MONOGRAPH OF THE GENUS
DENTALIUM.
Char. Gen. Molluscum corpore oblongo, testi elongati, tubu-
losi, conicd, arcuati, ad apicem perforati; apertura circular,
simplici; operculo nullo.
The shells of this genus are regularly conical curved tubes, open
at the apex, circular at the basal aperture. The worm-cases which
have the generic name Ditrupa, and which, of course, are not in-
cluded in this monograph, are distinguished from Dentalium by
being swelled and contracted near the aperture, instead of being
gradually conical.
Many species of Dentalium have a fissure at the dorsal edge
of the apical perforation. This being a somewhat irregular cha-
racter, even in individuals of the same species, and the fissure not
being formed in the growth of the shells, as in Emarginula, but
merely by subsequent “absorption or wearing, I cannot see in it a
sufficient indication of organic difference to justify the proposed
separation of the fissured species under the generic name “ AN-
TALIS.”
1. D. entare, Dinn., f. 50, 51. 52.—Testa levi, solidd, alba,
versus apicem rapidé crescenti et arcuati, deinde rectiusculd et
magis cylindricd; fissurd parva. —White, smooth, solid, at first
acuminated and curved ; afterwards cylindrical and nearly straight.
Fissure only seen in young specimens.
2. D. preriosum, Nuttall, f. 57.—Testa D. entali simillima,
sed angustiore, versus apicem haud tantiim arcuaté.—Less curved
and tapering near the apex than D. enfale, and altogether more
cylindrical. The distinctness of the species is doubtful.
3. D. tupricatum, Sows. Th. , f. 56.—Testa politi, elongata,
alba, subpellucida, leviter arcuata, vix fissurata, gradatim crescente.
—Certainly a narrower shell, less solid, andof more gradual increase
than either of the preceding.

98 DENTALIUM.
4. D. ruspuscens, Desh., f. 89.—Testa levi, rubescente, fasciis
rubris transversis variegati, gradatim crescente, leviter arcuatd, vix
fissurati.—A smooth: shell, of rather interrupted growth, of a red
colour, with darkish bands.
5. D. nesutosum, Desh., f. 58.—Testa politd, angusta, tenui,
alba, fasciis acuté angulatis pellucidis versus. apicem variegata ;
fissurd apicali lateralii—Besides the zigzag pellucid markings
near the small end of the shell, M. Deshayes has pointed out
that the fissure is not dorsal, but lateral, in position. This, how-
ever, is possibly accidental.
6. D. nacrrum, Desh., f. 48.—Testa levi, polita, tenui, lacted,
angusta, apice integro—Smooth, thin, narrow, and milky-white.
No fissure.
7. D. rranstucipum, Desh., f. 47.—Testd hyalina, subaureo-
flavescente, polita, tenui, subcylindrici, leviter arcuat4, apice ob-
tuso; fissura plus minusve elongat’.—Of a transparent amber-co-
lour. The slit, which is a mere linear crack, is in some istances
lengthened indefinitely.
8. D. sptenpipum, Sowd., f. 41.—Testi polita, versus apicem
attenuata, carned, deinde lactea, ad apicem fissuris duabus, altera
dorsali, alter’ ventraliimGenerally reddish near the apex and white
towards the base. In some specimens there are two fissures, one
dorsal and the other ventral.
9. D. rissura, Lamh., f. 43.—Testa polita, rubescente vel fla-
vida, gracili, subpellucida ; fissurd dorsali nonnunquam elongata,
nomnunquam fissurd brevi ventralii—This shell agrees better with
Lamarck’s description than the fossil figured in the genera. It is
more gracefully tapering and less transparent than D. ¢ransluci-
dum.
10. D. ronerrrorsum, Fve., f. 59, 60.—Testa polita, subaureo-
flavescente, elongata, validé arcuata, fissurd dorsali_ brevissim’i.—
A large, elongated, strongly bent, amber-coloured shell, with very
slight dorsal fissure.
11. D. epurneum, Zinn., £. 53.—Testd politd, pallidé fulva,
elongata, rectiuscula, annulis concentricis elevatis numerosis cinc-
ti; apice attenuata, vix fissurati.—The name has been wrongly
applied to the species with incised lines, which Linnzeus described
under the name of D. politum. T. eburneum is distinguished by
raised rings of circumference.
12. D. Puiierinarum, Sows. Th., f. 54.—Testé quam D.
ehurneo angustiore, magis diaphand, colore rubescente.—This is a
DENTALIUM. 99
brightly coloured, transparent shell, much narrower in proportion
than D. eburneum.
13. D. erecrum, Sowd. Th., f. 55.—Testé polité, angusta, vix
arcuati, medio et versus apicem rubescente, prope marginem alba,
utraque fissuraté.—This tapering shell is very little curved, the
narrow end is strongly coloured, the larger end white. ‘There is
a slit on each side of the apex.
14. D. rversum, Desh., f. 42.—Testd tenui, levi, angusta,
leviter arcuati, ad apicem rubescente ; fissurd apicali ventrali.—
The shell is narrower than J. splendiduwm, but similarly coloured.
Tt has a fissure on the inner or ventral side of the apex.
15. D. arrenvatum, Sow. Thes., f. 40.—Testd tenui, fulva,
polita, paululum arcuata, quam preecedentes angustiore ; apicé vix
emarginatd.—A shining, pointed, very narrow species, with a very
slight notch at the apex. It is nearly straight.
16. D. vistuta, Sowd. Thes., f. 62.—Testé subhyalina, an-
gusta, rectiusculd, apice integro.—The little fossil which M. Des-
hayes names D. duplex, is very much like the specimen here
figured from Mr. Hanley’s collection. Specimens in the British
Museum exhibit the character upon which the name is founded,
namely, the formation of a second tube where the original apex
has been broken off, and Mr. Hanley’s specimen shows a second
tube formed at the other end. The first being a habit common
to many other species, and the second being accidental, T should
decline using the name for its inapplicability, even if sure of the
identity of the species.
17. D. rrtum, Sowd. Thes., f. 45.—Testa tenui, angustissima,
levi, acuminata, pallidé fulva, apice integro.—We have specimens
of this, dredged by Mr. M‘Andrew, at Gibraltar, and others col-
lected at the Philippines, by Mr. Cuming. Notwithstanding the
difference of locality we can find no characters of specific import-
ance by which to distinguish them. They are of thread-like nar-
rowness, smooth, and without fissures.
18. D. sucrum, Desh., f. 35.—Testa angusta, lacted, polita,
subrecta, ad apicem obliqué sect, prope apicem tenuissimé striata.
—White, cylindrical, polished, nearly straight, with an oblique
cut across the apex, on the dorsal side.
19. D. porirum, Linn., f. 46.—Testa politd, leviter arcuata,
pallidé fulva, angusté, gradatim crescente, striis incisis obliquis
numerosis concentricis cinct’i; fissurd apicali elongatéi.—Mr.
Hanley, in his ‘Jpsa Linnei Conchylia,’ has rectified the long-
100 DENTALIUM.
standing error of applying Linnzeus’s name of eburneum to this
species, and that of podz¢wm to the shell to which Linneeus evi-
dently meant to apply the name eburneum. T. politum is distin-
guished from all other species by the incised lines which divide its
whole length into oblique rings. It is excessively rare in a recent
state, but well known among the fossils of the Paris basin. The
figure is from Mr. Hanley’s recent specimen.
20. D. topatum, Sowd. Thes., f. 44.—Testd subhyalina, validé
arcuati, curti, levi, alba, seu partim pallidé fulva; apice obtuso,
truneato, in lobis quatuor diviso.—This curious shell is smooth,
short, and strongly curved in proportion to its length. The apex
is divided into four lobes, the dorsal and ventral ones being each
slightly subdivided. This peculiarity may possibly indicate an
important difference in the animal structure, and until that is
known, we cannot be certain even of its generic position.
21. D. Tarentinum, Lamk., f. 19, 20, 49.—Testa solida, va-
lidé arcuaté, laté, albi, nonnunquam roseo-tineti, versus apicem
longitudinaliter striaté ; apice acuminato, plerumque integro.—
Unless much worn, specimens of this shell always show striz near
the apex, which, with the less cylindrical forms, distinguish them
from D. entale. The two species have, by some authors, been even
generically separated, on account of the absence of apical notch
in D. Tarentinum. In a numerous series of both species now
before us, however, we meet with cases where the notch is want-
ing in the former and quite traceable in the latter.
22. D. acutuatum, Sowd., f.63.—TestA alba, validé arcuata,
ineequaliter striat’ ; apice attenuaté, acuminata, integr.—Not un-
like the very young of PD. Zurentinum, but more acuminated, and
with unequal instead of equal strie.
23. D. currum, ”, f. 64.—Testé subviridi, subcylindracea,
tenué striata, brevi; apice obtuso, vix fissurato.—A small, cylin-
drical, pale-greenish shell, with obtuse apex and fine striz.
24. D. semivonitum, Sowd. Ser., f. 23.—Testd subhyalina, te-
nu, alba, angusta, versus apicem roseo-tincti, tenuissimé striata,
deinde polita ; apice nonnunquam antice aut lateraliter fissurato.—
Minutely striated at the narrow end, and quite polished from the
centre to the margin. More glassy and thin than D. Tarentinum.
25. D. Lessont, Desh., f. 15, 16, 17, 18.—Testa elongata,
leviter arcuata, pallide fulvé seu flavid’, nonnunquam roseo-tincta,
prope apicem 12-costata, deinde costis minoribus interstriaté, prope
warginem politi; apice integro—Rather variable, more or less
DENTALIUM. 101
cylindrical, numerously ribbed at the apex, with additional strice
afterwards, with a tendency to become smooth near the margin.
In the next species, D. dentale, this tendency is not observable.
26. D. penrate, Linn., f. 14.—Testa elongata, acuminata, 12-
costata, interstriati, pallidé rose’, transverse rubro-fasciati, apice
integro,—More distinctly ribbed than D. Lessoni, without the
same tendency to become smooth towards the margin. It is
banded with red.
27. D. Betcuert, Sows. Jun., f. 28, 29.—Testi subcylindracea,
eequaliter crebri-costaté, versus apicem leviter arcuati, alba vel
rosea, ad costas pallidé maculati; apice integro, obtuso.—It is
like D. novem-costatum, but with the ribs much more numerous.
There is a slight articulated appearance on the coste.
28. D. cancettatum, Sow. Jun., f. 36.—Testa tenui, alba,
acuminata, versus apicem validé arcuaté, costis circiter 8 longi-
tudinalibus et striis elevatis concentricis cancellata, deinde costis
numerosis, testd rectiuscula.—Cancellated near the apical end by
distinctly raised strive crossing the longitudinal ribs.
29. D. tirarum, Carpenter, f. 32.—Testi alba, parva, recta,
cylindrace’ ; costis longitudinalibus, zequalibus, circiter duodecim.
—A very small, white, straight, narrow, 12-striated shell.
30. D. vaRtaBILeE, Desh., {. 30.—Testi alba, cylindraced, an-
gust, prope apicem leviter arcuata ; costis inequalibus, pleramque
versus apicem paucis, deindé magis numerosis, plerumque quasi
articulatis ; apice integro.—The Tibs are usually few near the
apex, but at various lengths their number is increased by inter-
mediate ones, so as, in some specimens, to become numerous and
equal. They are spotted or articulated. It is much more narrow
and cylindrical than D. Belcheri.
31. D. zetanpicum, Sowd. Jun., f. 13.—Testd alba, pallidé
griseo et fulvo fasciatd, vix arcuati, pyramidal, lata ; costis nume-
rosis, paululum elevatis, ineequalibus ; apice vix fissurato.—Very
Has to D. rectum, but the sculpture far less bold and coarse.
D. recrum, Gmel., {. 1.—Test& crassi, magni, retrorsum
Pee pallida, p yramidali, subacuminata, ad aperturam lata ;
costis numerosis, ae Ineequalibus ; fissura apicali elongat4.—
This is figured and described by Deshayes, as D. elephantinum of
Linneus, with which it by no means agrees. It is coarsely and
unevenly ribbed, and has a backward curve in the centre, from
ee bending forward at the apex.

from a magnificent specimen in the collection of R. M‘Andrew,
Esq.; it is minutely cancellated by raised strize crossing the ribs.
34. D. rormosum, Ad. § Reeve, f. 2.—Testi arcuata,, acumi-
nata, ventricosa, coloribus viridi, rubro et fulvo alternatim fasciata,
15-costata ; costis validis, rotundis, zequalibus ; fissuraé medioeri.—

banded shell is the true D. ecephantinum, as shown by Mr. Hanley
in his shells of Linnzeus.

having eight instead of ten ribs, with broad flat surfaces between.
40. D. novem-costatum, Desh., f. 24, 25, 26, 27, 38.—Testa
solidi, plerumque rubra, fasciaté ; costis novem, solidis, rotundis,

species resembles D. dentalis, being generally of a reddish tint,
with darker bands. The light-tinted or nearly white variety is
small.

MONOGRAPH OF THE FAMILY
NUCULIDA,
FORMING THE LAMARCKIAN GENUS NUCULA.
By Sytvanus Hantey, F.L.S., ere.
YY ,
Tue essential ideal of a Lamarckian Nucu/a—1 do not mean
the genus according to the precise definition of Lamarck, for that
would scarcely include even the few shel!s he has indicated, but
Nucula so extended as to comprehend all the species which that
author, when he finally elaborated his system, would have lnked
together, had he known them—is a bivalve hinged by a series of
comb-like teeth. ‘hus simply characterized, its members form an
easily recognizable assemblage, which, however, the exigence of
modern classification compels us to subdivide as naturally as may
be.
The empirical school of conchologists, which prefers the arbi-
trary selection of a strongly characterized type, and the grouping
around it of such shells as resemble it in general aspect, to a strict
generic definition (in default of which a species may be adjudged,
even by an adept, to more groups than one), has distributed the
pristine Nueu/z into six genera or subgenera (Nucla proper, Leda,
Voldia, Portlandia, Solenella, Netto), placed far apart by D’Or-
bigny, and certain other naturalists, in different families. Without
arrogating to myself the skill to decide upon the rank, position,
and value of these sections, I have preferred to follow the more
moderate views of Woodward, because, while nothing is easier
than to discriminate between a nacreous Nueula proper, a porcel-
lanous Leda without a prominent ligament, and a porcellanous
Solenella with one, no adequate and universal characters by which
all the Yoldie and Portlandi@ may be indisputably distinguished
from all the Lede have ever been indicated. The published de-
finitions are either inapplicable to all, or would comprehend several
undoubted Lede.
VOL. IIT. M
106 NUCULIDA.
LEDA, Schumacher.
Gen. Char. More or less elongated, usually peaked behind, almost
always clothed with an epidermis, not nacreous within; margin
never crenated. Teeth pectinated, on both sides of an internal
cartilage. Pallhial line sinuated.
Sect. I. Lupa, proper.—Often strong, usually with an umbo-
nal ridge and concentric sculpture, only gaping at the posterior
tip, sometimes without an epidermis, which, if present, is more
often unpolished. Both dorsal areas usually impressed or defined,
almost always sculptured. Pallial situs small or moderate.-—The
four final species (especially the last two), Micobarica, serotina,
lenidula, and tenella, are intermediate in character between this
and the next section.
Sect. II. Youpra, MWé//er.—Gaping at both ends, rarely with
an umbonal ridge, usually fragile, usually with an epidermis, if so
always a polished one (except, perhaps, in 7Zraci@formis), never
ribbed, nor radiatingly sculptured, Dorsal areas rarely, if ever,
sculptured, their lips usually pouting ; front dorsal area rarely im-
pressed or defined. Cartilage-pit usually large, cochleariform, or
broadly triangular, shelvingly projecting: inwards. Pallial sinus
usually large.
Sect. Ul. Porrtanpia, Mérch.—Resembling the last, but
closed at both ends.
Sect. I. Lepa, proper.
1. L. nnoneara, Sowd., f. 39.—T. cymbeeformis, utrinque hians
et obverse subcuneiformis, equilateralis, compressa, semipellucida,
striis pertenuibus et anticé remotioribus longitudinaliter scalpta,
postice leevigata, cute mitidi tenuissima fulva vel olivaceo-cinered
induta. Extremitas antica aliquantulum latior, magisque rotun-
data ; postica subbiangulata. Margo dorsalis horizontalis ; ventra-
lis in medio rectiusculus vel subretusus, utrinque convexiter accli-
vis.— Boat-shaped, thin, semitransparent, more or less compressed,
gaping at both ends (more so in front), white under an excessively
thin epidermis, which in aged examples is olivaceous ash-coloured,
but in less matured ones is shining, bright fulvous, and only
conspicuous near the margins; posteriorly smooth, elsewhere
scratched lengthways with shelving strie, which are so fine above
as to appear obsolete, are close, fine, and regular in the middle,
more remote and concentric in front. No umbonal ridge, but an
indistinct shallow indented ray in front. Sides equal, or very
NUCULID&. 107
nearly so, obversely subcuneiform, almost similar, but the front one
is slightly the broader and more rounded, the hinder slightly the
more tapering, and subbiangulated at its extrennty. Dorsal edge
horizontal, very slightly flexuous (plano-convex in front, plano-
retuse behind). Ventral margin subarcuated, the arch usually <
little straightened or even subretuse in the middle, convexly rising
at both ends, yet with a slight retusion in front, and in a straight-
ened line behind. Beaks not at all elevated. Dorsal areas in-
conspicuous, the hinder one flattened. Teeth most numerous on
both sides ; pit shallow, broadly triangular, sunken.
2. L. Sowrrsiana, D’Ord., f. 33.—T. L. elongate simillima,
sed nivea, angustior, utrinque acutior, et fere usque ad extremi-
tatem posticam scalpta strus arctioribus, quarum anticé et con-~
centrice sunt etiamque obliqué longitudinales. Arez dorsales trans-
versim costulatee.—Iridescent, snow-white, most closely resem-
bling elongata, yet rather narrower, and with more taper extremi-
ties. The stri, also, which are still finer and closer, and just in
front are both concentric and obliquely longitudinal, extend as far
as the ordinary site of an umbonal ridge. Dorsal areas more or
less distinctly cross-barred. In adult examples the fine central
striz (at least in one of the valves) seem raised, and the lines of
growth cut the somewhat slanting longitudinal ones before the
smooth site of an umbonal ridge. In the young the escutcheon
is excavated, and its edges crenulated: the hinder extremity of
the valves, moreover (as may be seen in the nuclear portion of the
full-grown shell), is, also, subobliquely striolate. D’Orbigny,
aware that the South American /anceolata of Sowerby was not
identical with the Lamarckian one (a species without adequate
definition, either verbal or pictorial), termed it (Voy. Amér.
Mérid. Moll., p. 544) Sowerdyana, but with his usual carelessness
referred to the figure in the ‘Genera’ (edecfa), instead of that in
the ‘ Illustrations.’
3. L. Pataconica, D’ Orbigny, f. 49, 50.—T. angusté oblongo-
rostrata, compressa, albida, equilateralis, undique longitudinaliter
striata ; strize anticé remotiores. Hxtremitas rostri attenuati re-
curvata, suboblique truncata. Margo dorsalis anticus rectiuscu-
lus, vix declivis; posticus valde incurvatus, paululum declivis.
Area magna excavata, carina plicee umbonalis simplici circum-
scripta.—Of a much-produced beaked-oblong shape, rather thin,
compressed, whitish, with a very shallow radiating indentation
anteriorly, before which the close-set shelving subcoucentric striz
that elsewhere traverse the entire surface become more distant,
108 NUCULID&.
and are cross-hatched, as it were, by true concentric ones. Sides
equal, or very nearly so. The front extremity bluntly rounded ;
the beaked hinder side gradually attenuated to a very narrow,
rather oblique, truncated, recurved tip. Front dorsal edge straight-
ish, nearly horizontal; hinder dorsal slope slight, much incurved.
Ventral margin arched in front, much and convexly rising behind,
neither retuse in front nor centrally. Escutcheon excavated,
large, carinately defined by the projecting, nearly simple (7. e. not
distinctly crenulated) edge of the umbonal ridge, which latter is
planalate, and inconspicuous. Lunule narrow, not well defined.
Cartilage-pit broadly triangular. ‘Teeth very numerous on both
sides.
4, L. Trxtinormes, Sowerby, f. 36.—T. lanceolato-elliptica,
antice rotundato-acuminata, flexuosa, subeequilateralis, nivea, com-
pressa, nisi posticé undique striata: striz anticee longitudinales ;
medi oblique curvatee. Margo dorsalis uterque vix declivis, an-
ticus plano-convexus, posticus vix retusus. Areze dorsales incon-
spicue.—Hlongated, lanceolated-elliptic, slightly flexuous, bend-
ing down a little in front, and inclining upwards a little behind ;
thin, glossy, snow-white, compressed ; smooth behind, elsewhere
striated : striz curved and slanting in the middle, almost concen-
tric in front. Sides very nearly equal, gradually and nearly equally
tapering to either extremity; anterior end rotundately peaked ;
posterior end angular above, rounded below. Dorsal slopes very
slight ; the front one plano-convex, the hinder one barely subre-
tuse. Ventral margin subarcuated throughout, with an extremely
slight anterior, and no posterior, retusion. Dorsal areas incon-
spicuous ; the hinder one impressed, its edges minutely crenulated.
Teeth very numerous on both sides.—Besides the longitudinal
strie, a few symmetrical lines of growth may be discerned beneath
the front dorsal edge, and a few still more indistinct ones (but no
striz) on the opposite side. In mature examples similar lines are
likewise manifest in the middle, near the lower margin.
5. L. etortosa, 4. Adams, f. 42, 43.—T. angusté lanceolata,
nivea, in medio tanttim inferne compressa, ante radium impressum
anticum plicis planulatis latis, et pone eum stris inclinatis arctio-
ribus, concentrice sculpta; posticé multiim longior, obtuse acu-
minata, Mcurvatione utriusque margimis coarctata. Margo dorsalis
anticus plano-convexus vix declivis; ventralis anticé arcuatus.—

the ordinary site of an umbonal ridge not elevated, but convex
and smooth, elsewhere regularly and concentrically sculptured, by
broad imbricated flattened folds before the indentation, by twice
as numerous close shelving striz behind it. Front side much the
shorter, unsymmetrically rounded at the extremity. Hinder side
rapidly contracted by the incurvation, behind the beaks, of both
upper and lower edges, then gradually acuminated to a bluntly
oblique extremity, the tip being more prominent dorsally. Front
dorsal edge scarcely sloping, plano-convex ; hinder dorsal slope
rather slight, much produced, plano-retuse. Ventral margin
arcuated in front, rising, after the central retusion, with little
convexity. Hscutcheon carinately defined, rather broad. Lunule
just perceptible. Cartilage-pit small, triangular. Teeth numerous,
particularly behind.—The epidermis is of a yellowish ash-colour.
6. L. nxecra, 4. Adams, f. 40, 41.—T. anguste lanceolato-
rostrata, utrinque attenuata, eequilateralis, nivea, compressa, un-
dique longitudinaliter striolata: striole anticee minus conspicue ;
postice arctiores, magisque oblique. Hxtremitas postica obliqué
subtruncata. Margo dorsalis posticus incurvatus, vix declivis ;
ventralis in medio arcuatus. Area impressa, crenato-marginata.
—Hlongated, beaked-lanceolate, thin, compressed, shining white,
everywhere minutely yet distinctly sculptured; shelvingly scratched
lengthways by fine strize, which in front (where they are crossed
by the wrinkles of growth) are more distant and less manifest,
and become closer and more slanting posteriorly ; the scarcely
raised extreme posterior ridge is smooth to the eye, yet is barred
with raised concentric wrinkles. Sides equal or very nearly so ;
the anterior one gradually tapering to a narrow rounded tip; the
posterior one beaked and still more attenuated, the extreme tip
obliquely subtruncated and angulated above. Front dorsal slope
moderate, convex ; hinder dorsal slope, slight, incurved. Ventral
margin arched in the middle, rising at both ends, barely subretuse
in front. Beaks minute, sharp, perceptibly projecting. Escutcheon
sunken, crenately margined. Lunule perceptible.
7. L. Taytor1, Hanley, f.35.—T. elongata, anticé aliquantum
brevior et rotundato-lanceolata, posticé attenuata et subrostrata ;
nivea, subcompressa, densius longitudinaliter striata: stris anticé

sinistra ubi inferné prope plicam umbonalem planulatam demumque
sublevigatam prorsus desunt) magis minusve oblique. Margo
dorsalis uterque vix declivis. Area planulata, crenulato-margi-

110 NUCULID®.
attenuated and subrostrated behind, rather compressed, shining
white, striated lengthways throughout (except a small triangular
space in the lower corner of the left valve just adjacent to the
planulate umbonal ridge, which latter is also somewhat smoothish
near its termination) ; striz: very close (rather less so in the front
of the right valve), raised and concentric in front, then shelving
and (at least im the left valve) more or less slanting. Dorsal edge
but little sloping on either side, plano-convex in front, plano-
retuse behind. Ventral margin much arched, rising almost
equally at both ends. Beaks little promiment. Escutcheon nar-
row, flattened, well defined by the very prominent crenulated edge
of the umbonal ridge. Front dorsal area less conspicuous, con-
centrically striated. Cartilage-pit broadly triangular, subemargi-
nated below, sunken. Teeth numerous, especially behind.
8. L. crentrera, Sowerby, f. 37, 38.—T. anguste oblongo-
lanceolata, subzequilateralis, convexa, posticé rostrata et valde

retusus, declivis. Area magna, levis, margine crenulato plice
umbonalis circumscripta. Lunula magna, planulata, plicA angustaé
marginata.—Of an elongated oblong-lanceolate form, dull white,
convex, concentrically striated (the lunule excepted) throughout :
strie for the most part extremely fine and close, less so on the
narrow and scarcely elevated umbonal ridge (where they become
shelving), and just after a narrow fold that bounds the large and
flattened front dorsal area. Sides nearly equal: the front ex-
tremity attenuated, not well rounded above, very obliquely so
below: the beaked hinder side much and gradually attenuated,
its tip nearly central, very small and subtruncated. Front dorsal
slope very slight, plano-convex ; hinder dorsal slope moderate,
retuse. Ventral margin arched in front, retuse before the hinder tip.
Escutcheon large, smooth, well defined by the crenated edge of
the umbonal ridge. ‘Teeth numerous, especially behind.—Judging
from the nuclear portion, which is somewhat remotely lamellated,
and by no means elongated, the fry may readily be mistaken for a
distinct species.
9. L. Merroatret, Hanley, f. 34.—T. elongata, compressa,
striis densis et argutis, quee ante radium impressum anticum re-
motiores sunt et Jamellose, posticé autem elevate et valde oblique

tus. Are sicut in L. creniferd.—Of a produced beaked-oblong
shape, very inequilateral, not very thin, compressed, whitish,
without an elevated umbonal ridge, with a well marked anterior
broadish indented ray, before which the very fine close-set longi-
tudinal wrinkles, which become raised and very oblique posteriorly,
are lamellar and more distant. Hxtremity of the much shorter
anterior side subangulated and more projecting above, obliquely
rounded below. Hinder side much and gradually attenuated,
beaked ; its recurved tip narrow, obliquely subtruncated. Dorsal
slopes very slight ; the front one plano-convex ; the hinder one
incurved. Ventral margin much rising at both ends, arching up
obliquely in front, convex behind. Beaks acute, scarcely pro-
minent. Dorsal areas as in erenifera. Cartilage-pit small,
sunken, triangular. Teeth very numerous, especially behind.—In
the largest only of the three individuals known to me (one of
which perchance may be adult) do the oblique strize extend to the
crenated ridge. The ventral margin is slightly indented a little
beyond the middle, and just before its hinder termination.
10. L. prcora, A. Adams, f. 47, 48,—T. subequilateralis,

ther small, convex or subventricose, gaping slightly at both ends,
dull white, concentrically lyrated (the dorsal areas excepted)
throughout : the lyrated wrinkles very small and crowded, except
upon the umboes, upon a ray-like anterior portion (where they
are irregular and coarser), and along the umbonal ridge, which
latter is retuse in the middle, and undefined anteriorly. Sides
nearly equal; extremity of the slightly shorter anterior one nar-
rowed, and symmetrically rounded: posterior side attenuated,
gradually beaked ; its tip narrow, recurved, obliquely subtruncated.

declivis ; posticus incurvatus. Labia areee magne, levis, concave,
protrusa.—Peaked elongated-oblong, rather thin, compressed,
under an ashy or pale olivaceous ash-coloured epidermis glossy
white, concentrically traversed by distant erect lamellae, which ter-
minate just before an umbonal ridge that is formed by two crest-
like squamose ridges enclosing between them a flattish and nearly
smooth area; intervals of the lamelle unsculptured. Extremity
of the moderately yet decidedly shorter anterior side attenuated,
and unsymmetrically rounded: hinder side gradually beaked ; the
tip fine, biangulated, subcentral. Front dorsal slope very slight,

at the extremity. Ventral margin arcuatedly rising in front, less
so behind, slightly indented before the posterior tip. Escutcheon
large, smooth, concave, yet with pouting lips. Lunule linear,
smooth, conspicuous. ‘Teeth on either side of the very small

sionally iridescent. A more or less obsolete anterior indented ray
is generally perceptible.

subangulated dorsally in front, attenuatedly beaked behind, rather
thin, much compressed, only gaping at the very narrow biangu-
lated and scarcely upturned posterior tip, covered with a thin
greenish-cinereous epidermis, devoid of marked anterior indented
ray, with a narrow umbonal ridge, which is subspinosely keeled
on either side. General surface concentrically lamellated ; inter-
vals of the lamellae, which are much more remote on the umboes,
and somewhat more distant in front, smooth. Front dorsal slope
slight, nearly straight ; hinder dorsal slope rather slight, retuse.

pressed behind, from convex to subventricose in the middle, with
a more or less manifest indentation radiating with little obliquity
from the beaks to nearly the front extremity of the opposite
margin, clothed with a glossy epidermis that ranges in tint from
yellowish-olive in the adult to olivaceous-yellow in the young,-
very closely and finely sculptured by raised concentric wrinkles,
which, coarser and more distant before the indentation, become,
for the most part, wholly or partially obsolete towards and upon
the umbonal ridge (except, perhaps, above) and lunule, and are
usually less conspicuous on the left valve. Posterior side about
twice as long as the anterior (which is unsymmetrically rounded),

ventricose, and only compressed near the hinder termination. The
hinder side only occupies three-fif hs of the total length, and tapers
more abruptly than im the preceding species: the concentric

as to abruptly pinch up the subcentral (and somewhat cocked-up)
tip of the rostrum. Lips of the escutcheon, which is large, and
clearly defined by an almost carinated rim, pouting. Lunule in-

Area lanceolata, subduplex ; interior sublevigata, planulata; ex-
terior concava, sulcis inclinatis obliqué sculpta. Lunula planulata
et obliqué striata.—Oblong-lanceolate, compressed, except at the
umboes, which are convex, or even subventricose, scarcely gaping,
of a polished ivory-white, smooth on the central umbonal region
and posterior third, elsewhere concentrically graven with rather
distant imbricating sulci. Anterior side slightly longer, its ex-
tremity a little attenuated, and unsymmetrically rounded. Pos-
terior side peaked ; the tip rather above the middle, with a short
dorsal retusion. Front dorsal edge nearly straight, scarcely sloping :
hinder dorsal edge straight or subretuse, a little sloping. Ventral
margin regularly arched, much rising at both ends (obliquely so
in front), devoid of retusion. Escutcheon lanceolate, well defined,
subbipartite ; the flattened top nearly smooth ; the concave lower
portion obliquely marked with distant imbricating sulci. Lunule
manifest, flattened, obliquely striated. Interior subiridescent.

carina definita ; labiis protrusis. Lunula nulla. Dentes utrinque
permulti.—Hlongated oblong, twice as long as broad, without
anterior indented ray, but in its ordinary place marked towards
the lower margin with a few very obsolete radiating grooves.
General surface (polished, fide Hinds) traversed by shelving some-
what slantingly longitudinal sulci, which are fainter in front and
on the somewhat depressed umboes, and cease suddenly near the
posterior end, leaving a planulate narrow strip, which is crowded
with concentric wrinkles or striz. Hinder triangle smoothish or
finely wrinkled concentrically, and divided into three areas by a
carinated line, which bounds the escutcheon (which is concavely
impressed, but with pouting lips) by a very abrupt sinking of the
surface which angularly limits the lowest ared in front, and by a
slightly raised radiating line, which stands halfway between these
two. Extremity of the slightly shorter anterior side attenuatedly
rounded ; posterior side not beaked, sinuously subtruncated, being
angulated by the triple projection of the radiations. Front dorsal
slope decided, plano-convex ; hinder dorsal slope rather slight,
incurved. Ventral margin merely convex in front, straightish
and without indentation behind. No defined front dorsal area.
Teeth very, and nearly equally, numerous on either side of the
rather large, shelving, triangular cartilage-pit. Mr. Metcalfe
possesses two dead left valves. As the central keel does not
extend to the umboes, it is probably wholly absent in the fry.

extremely shallow broad indented ray, and behind by a very sud-
denly excavated acutangular curved triangle that is notched at
the base, is dorsally raised and squamosely imbricated, ventrally
simple and subcarinately angulated. Surface everywhere sculp-
tured by rather fine flexuously curved shelving strie, which, for
the most part, run obliquely downwards with a double curve from
the front umbo, but before it arch in an opposite direction. Sides

lanceolata, sublevigata. Lunula inconspicua.—Produced ovate-
oblong, a little subcylindraceous, more or less ventricose, ivory-
white, with about 3 narrow, close, prominent folds at the extreme
front, and a posterior triangle, composed of a broad, smooth con-
cavity, flanked by serrated keels (two approximate ones above, and
one below), the ends of the two larger of which form two pro-
jecting points: surface elsewhere finely graven by numerous wavy,
downwards-slanting, incised lines, whose intervals rise at the
umbonal region into raised strize. Extremity of the anterior side,
which occupies about two-fifths of the total length, rounded:
extremity of the attenuated posterior side biangular, deeply
notched. Front dorsal slope moderate, convex: hinder dorsal
slight, straight, or subretuse. Ventral margin arched in front,

Beaked-oblong, subventricose, the ordinary site of an umbonal
ridge occupied by a kind of lattice-work formed by several ra-
diating linear keels and rather distant, transverse, raised strive ;
ivory-white (sometimes very pale tawny), rather glossy, everywhere
(dorsal areas excepted) waved with flexuous, closely disposed,
subimbricating sulci, which, concentric at the nucleus, and some-
what so in front, become arched and slanting posteriorwards. Sides
very nearly equal; front extremity very uns) mmetrically rounded :

hinder side quickly forming an upturned beak, of which the rather
narrow tip is convex, and above the middle. Front dorsal slope
slight, straightish ; hinder dorsal slope moderate, deeply incurved.
Ventral margin much arcuated, rising obliquely in front, not re-
tuse behind. Escutcheon large, defined, finely grooved length-
ways. Lunule inconspicuous. Teeth numerous on both sides.
Judging from the nucleus, the fry may readily be mistaken for a
distinct species. Montagu described the species as new, and not
as of Gmelin, whose rostrata was identical with pernula.
25. L. Cuuva, Gray, f. 67.—T. ZL. erasse simillima, brevior

Lyre plicee umbonalis nonnunquam inferné subobsoletee.— Most
closely resembling crassa, but is peaked-ovate ; the slopes are con-
sequently more decided, and the ventral margin more arched ; the
peak is rather more acuminated, and higher seated ; the lyre, too,
are scarcely so prominent, and the arched ones on the umbonal
ridge become, occasionally, almost obsolete at the lower extremity.
The difference between this and crassa, var. brevior, is very
trifling.

umboes and towards the umbonal ridge, which latter is neither
elevated nor defined in front. Sides equal, or very nearly so:
anterior extremity rounded ; posterior side rather abruptly beaked,
the tip, which is either in the middle or just above it, upturned
and sharply angular. Front dorsal slope very slight, convex, with
a sudden terminal retusion. Hinder dorsal slope moderate, at
first straightish or plano-convex, eventually rather suddenly in-
curved. Ventral margin much rising at both ends, arcuated (at
the least, in front), devoid of retusion. Dorsal areas large, pouting,

closely grooved concentrically ; the much broader intervening lyre
subimbricated in front, rounded behind. Sides very nearly equal ;

radiating indentation (which waves the sulci), rounded at its ex-
tremity. Posterior side quickly tapering, subrostrated ; the tip
of the upturned beak very narrow, higher than the middle of the

may be discerned on the umbonal ridge (the projection of the ribs
upon which is a salient characteristic), and sometimes, too, on the
outer portion of the front ventral margin. Were it not for the
intermediate form, the produced variety ? (for which, if a species,
I would suggest the name pyriformis, but have only as yet seen a
single specimen) could not possibly have been identified with the
more typical (or rather the first delineated) form, the peculiarities
of which seem only developed in mature examples.

the hinder tip, of a polished ivory-white, with a very faint anterior
indented ray, closely grooved lengthways throughout; the sulci
shelving, except upon the beaks and near and upon the feebly
developed umbonal ridge, where they become broader and square-
cut, and their intervals form costelle. Anterior extremity rotun-

side attenuatedly beaked, its tip, which is contracted at its origin
both above and below, very narrow (yet blunt), peculiarly upturned
(in the adult), and above the middle. Front dorsal slope very
slight, straightish or plano-convex: hinder dorsal slope with a
double incurvation. Ventral margin much arcuated in the middle
and front, straighter behind, much rising at both ends, slightly
retuse near its posterior termination. Dorsal areas smooth or

concave, environed by a deep, broad sulcus, which angulates its
sides, and makes it appear raised.—Under a powerful glass, a few
radiating lyre may be descried near the commencement of the

met with this species in good condition. The teeth seem to
average about eighteen on one side and twenty on the other. Of
the three names bestowed by Chemnitz I have preferred WVico-

one straight or subretuse. Ventral margin arching obliquely up-
wards in front, convex behind, bending abruptly up at its termi-
nation. Escutcheon lanceolate, carinately defined, more or less
smooth. Cartilage-pit sunken, triangular. ‘Teeth numerous.—
In the variety Zepzda, the hinder side is more gradually attenuated
to a slightly more slanting tip, and the sulci are partially absent :
in the form serotina the latter traverse the whole middle area, and
the lunular region is slightly more prominent.

inequilateral, more spread and less ventricose in proportion. The
valves are thin, and gape at both extremities, the epidermis is of
a very pale olivaceous ash-colour ; the ventral margin, in the adult,

hinder extremity, which is blunter and less oblique than in fene//a.
There is not the least trace of an umbonal ridge. The front dorsal
edge is decidedly convex at the extremity. The beaks are pecu-

small, subventricose at the umbonal region, gradually compressed
behind, ivory-white (sometimes of a yellow cast), glossy, smooth
to the eye, but under a powerful glass most minutely and closely
striolate; the extreme front strivle nearly concentric, the next
sloping downwards and backwards, the hinder, which do not,
however, extend to the extreme verge, radiating, and, if possible,
still finer. Extremity of the anterior side, which occupies about
two-fifths of the total length, and gapes considerably below, un-
symmetrically rounded. Posterior side neither beaked, nor much
attenuated, but with a rounded-off angle above; the hinder tri-
angle not defined by a distinct umbonal ridge, but well marked
near the umboes by the sudden decrease of the general convexity.
Front dorsal slope slight, short, plano-convex : hinder dorsal edge
scarcely sloping, at first subretuse, eventually plano-convex. Ven-
tral margin obliquely arching upwards in front, subretuse in the
middle, then convex and meeting the dorsal edge in an oblique
and straightish line. Escutcheon peculiarly narrow (obscurely
grooved 2). Lunule larger, well defined, finely striolate length-
ways.—The epidermis is extremely thin, and somewhat iridescent.

dentation radiating from the acute beaks (which are reflected and
by no means prominent) to both ends of the ventral margin, and

beaked behind (posterior lip convex), covered with a polished
cuticle which is brownish-olive, greenish-olive, or pure olive, in
rather broad lighter and darker zones, smooth, except ventrally,
where the surface is coarsely and remotely wrimkled concentrically.
Dorsal edges little sloping; the front one convex, the hinder one
barely retuse. Ventral edge retusely straightened in the middle,

bonal ridge, clothed by a highly polished olive epidermis, whose
zones of increase are more intense or blackish, smooth, except for
the wrinkles of growth. Anterior side slightly the longer, almost

subtruncate at the extremity, which is subcentral, but projecting
more above the middle. Front dorsal edge arcuated, and mode-

(near the slopes excepted) conspicuously decussated by irregularly
concentric costellar or lamellar wrinkles, pairs of which often be-
come confluent anteriorly, and close-set radiating raised lines.
Anterior extremity somewhat tapering, chiefly projecting below
the middle, rounded; posterior end rotundately subangulated
below, its dorsal slope very decided. Ventral margin closely cre-
nated within, more rising in front, at times much arcuated in the
middle, at times (in the very inequilateral specimens) only slightly
so. Lunular area rather large, pouting, more or less angularly
defined, for the most part subgranosely wrinkled near the cir-
cumference, smoothish in the middle: opposite dorsal area rather
flattened, usually obscurely barred with wavy pliciform wrinkles,
which generally become obsolete with age. ‘Teeth about twelve
on the shorter side, and twice as many on the longer.—There
are three known variations. The North British form, where
the wrinkles are almost lamellar, and the shape is somewhat more
ovate; the N. African form, where the wrinkles are costellar
and shelving, and the shape triangular; and the Mediterranean
form, where the sculpture is comparatively undeveloped and the
form intermediate between the two previously indicated. Mr.
Cuming possesses an aged example (seven-eighths of an inch in
length) in which the radiating lines appear incised near the lower
margin, and the smooth lunular area is devoid of the ordinary
sculpture, projection, or definement.
2. N. nucteus, Lin., f. 121,122,159.—T. obovato-trigona, raro
obliqua, satis ventricosa, valida, cute luted vel olivaced et nun-
quam nitida induta, nunquam colore radiata, in medio sublevigata,
utrinque tenuissimé concentricé subplicato-corrugata et (posticé
presertim) minutissime radiatim lirata. Hxtremitas brevior ro-
tundato-obtusangularis, inferné eminentior. Margo ventralis satis
arguteé crenulatus, arcuatus, posticé acclivis. Nates prominentes,
inclinate. Lunula nitida, concentricé corrugata, neque granis
nec lineis radiantibus sculpta. Area aut levigata aut concentricé
sculpta.—Obovate-trigonal, almost always longer than broad, sel-
dom oblique, strong, moderately ventricose, clothed with an
epidermis that is never polished or colour-rayed: general surface
smoothish in the middle but very finely concentrically and sub-
pliciformly corrugated at both ends, and, under a lens, (particu-
larly behind) perceptibly, though faintly, closely radiatingly lyrated.
Inequality of the sides decided, yet not remarkable ; extremity of
the anterior side, which is produced and tapering, rounded off ; its
chief projection basal. Posterior end rotundately obtusangular,

and rather prominent below. Ventral margin rather finely crenated
within, arched, rising posteriorly. Beaks prominent. Lunular
area shining, rather obscurely, yet impressly defined, somewhat
pouting, concentrically wrinkled, without radiating lines or granules.
Opposite dorsal area smoothish or concentrically wrinkled. About
twenty teeth on one side, and ten on the other.—The northern and
southern forms differ to some considerable extent; the surface in
the former is comparatively smooth, and its epidermis is yellowish ;
in the latter (or at least in the Mediterranean examples*) the
epidermis is of a dusky-olive, the sculpture is much more decided,
and the radiating lines often pervade the central portion likewise.
Bruguiére’s description of his 4. margaritucea (Hist. Nat. Vers,
109), for which Arca nucleus of Linnzeus is indicated as a probable
synonym, is rather generic than specific; he admitted but a single
species of wacreous Arca, which he ascribed to St. Domingo, but
referred likewise to England as a habitat, on the authority of Da
Costa. As Petiver’s rude figure (Gaz. pl. 17, f. 9) of the present
species is cited by him as the most characteristic, we may fairly
regard his margaritacea as, in the main, identical with the com-
monest of our known Nucule.
3. N. srrtotata, Adams, f. 129.—T. sp. preecedenti simillima,
sed semper pallidé olivaced, magis obliqua, compressa, subleevigata
(oculo autem armato undiqne striolis vix elevatis dense radiata) ;
ruge concentrice obsolete et equaliter diffuse. Lunula haud
definita.x—Closely resembling nucleus, but more oblique, com-
pressed, always of a pale-olive, smooth to the eye, but under a
powerful lens the general surface everywhere densely radiated
with scarcely raised striol : the concentric wrinkles obsolete and
evenly diffused. Lunular area undefined.—The likeness to a young
Mediterranean xucleus is most striking. Owing to the thinness
of the epidermis there is an external iridescence around the lunu-
lar area.
4. N. rapiata, Hanley, f. 123, 124.—T. N. nucleo simillima,
sed major, longior, magis obliqua magisque inequilateralis, radiis
aliquando rubro-aurantiis nonnunquam fumosis picta, magis
minusve compressa. Cutis nitidiuscula, olivacea, in junioribus
olivaceo-lutea.—With the shape, sculpture, and general characters
of nucleus, but larger, longer, more oblique, still more inequilateral
* T suspect that the WV. rugudosa of Sowerby (Conch. Ilust. Nucula, n. 28, f. 19,
copied in Hanl. Rec. Bivalves, p. 171, pl. 20, f. 10) was constituted from this variety ;
at least, I know no species which so greatly resembles it. It is thus deseribed :—
“ Ovate-triangular, with a greenish epidermis, covered with rugulose strise; angles
obtuse ; anterior (7.e. posterior) slope with a central elevation ; posterior (.¢, anterior)
slope somewhat rounded ; ventral margin very finely crenulated, 0°5.”

(the beaks being almost terminal in the adult), and less prominent
behind. More or less compressed, and under a not quite dull
epidermis, that ranges in tint from olivaceous-yellow in the young
to deep-olive in the mature, colour-rayed ; rays for the most part
narrow and smoke-coloured, sometimes (especially in the young)
orange-red, and broader; sometimes painted with both colours.
The lunule is elongated, but less prominent than in xweleus.—
There is more posterior projection in the fry, but at that stage the
elongated shape is peculiarly conspicuous and the rays more vivid.
5. N. castanua, A. Adams, f. 130.—T. conspicué obliqua,
latitudine longitudinem equante, compressa, cute luteo-castanead
induta, haud radiata, sublevigata. Margo dorsalis anticus arcuatus,
elongatus. Latus posticum fere nullum, inferné acclivitate repen-
tind marginis ventralis multum arcuati et arguté crenulati obliqué
excisum. Lunula valde prominens, bene definita.—Peculiarly
oblique, about as broad as long, compressed, invested with a rather
glossy, yellowish-chestnut epidermis, not colour-rayed, everywhere
almost smooth, merely obscurely wrinkled concentrically, devoid
of radiating or divergent sculpture. Anterior extremity narrowed,
yet well rounded ; front dorsal edge peculiarly elongated and arched.
Posterior side scarcely any, obliquely cut off below by the abrupt
ascent of the much arcuated ventral margin, which is finely crenu-
lated within : lunular region peculiarly prominent and well defined.
—Mr. Cuming and Mr. Metcalfe each possess a single specimen.
6. N. nrrmua, 4. Adams, f. 142.—T. obliqua, ovato-conoi-
dalis, eequé lata ac longa, haud ventricosa, valde inzequilateralis ;
cute polita pallidé olivacei, zonisque nigro-cinereis cincti, induta,
undique levis. Margo ventralis crenulatus, valde arcuatus, posticé
conspicué acclivis. Latus anticum rotundato-subcuneiforme. Nates
prominentes. Lunula subangulatim definita, multum eminens.—
Oblique, ovate-conoidal, as broad as long, by no means ventricose,
extremely inequilateral, with a polished pale olive-coloured epi-
dermis, and dark grey zones, everywhere smooth. Ventral mar-
gin crenulated within, much arcuated, rismg behind so as to
obliquely round off the posterior corner. Extremity of the sub-
cuneiform anterior side rounded, front dorsal slope very decided,
much produced. Beaks acute, prominent, touching. Lunular
area much projecting, subangularly defined.
7. N. nrrmpa, Sowd., f. 120.—T. ovato-trigona, satis ventri-
cosa (in exemplis junioribus compressa), cute nitidissima oliv-
aceo-cinerea induta, nonnunquam lineis fumosis radiata, rugis
subpliciformibus concentricis striisque radiantibus subobsoletis

crenulatus multum arcuatus, posticé satis repenté acclivis. Areze
dorsales tantum lineis incrementi rudé corrugate ; lunula haud
definita, haud prominens. Margo cardinalis subangustus.—Ovate-
trigonal, subventricose (compressed when young), clothed with a
highly polished ashy-olive epidermis, occasionally marked with
smoke-coloured linear rays: with concentric subpliciform corru-
gations and very faint radiating stric at the broader end, rather
less manifest ones on the narrower end; intermediate surface
nearly smooth to the eye, but under the lens (the epidermis being
removed) marked with radiating incised lines. Lower extremity
of the peculiarly short hinder side angularly prominent, dorsal
slope abrupt. Anterior end subangulately rounded. Ventral
margin crenulated within, much arcuated, rather suddenly rising
behind. Beaks sharply prominent. Lunular area undefined, not
prominent, and as well as the simple, somewhat flattened front
dorsal region merely coarsely wrinkled by the lines of growth.
Hinge-margin rather narrow: teeth as in xucleus.—The N. ar-
gentea of Brown (Lllust. Conch. G. B., p. 85, pl. 33, f. 14, 15) is
probably the fry of this species.
8. N. proxima, Say, f. 118, 119.—T. subtrigona, valde in-
eequilateralis et obliqua, latitudine longitudinem fere equante,
valida, ventricosa, cute nitida olivaceo-cinered induta, subleevigata.
Latus posticum inferné haud angulatum, acclivitate conspicud
marginis ventralis crenati multumque arcuati obtusé excisum.
Margo dorsalis anticus valde declivis, rectiusculus. Nates erose.
Lunula haud prominens, sulco tenui (in adultis) circumscripta,
haud divaricatim insculpta. Margo cardinalis latus—Var. T.
perobliqua, cute olivacea, lunula haud circumscripta.—Subtrian-
gular, very oblique, nearly if not quite as broad as long, ventricose,
clothed with a thin glossy olivaceous ash-coloured epidermis, when
adult smooth except for the pliciform wrinkles of increase, which
are often conspicuous on the dorsal regions, and some very faint
radiating strie, which are most perceptible below posteriorly.
Ventral margin crenated, much arcuated, much rising behind, so
as to cut off without angularity the posterior corner. Front
dorsal slope straightish, produced, very decided. Beaks almost
terminal, peculiarly inflected, always eroded. Lunular region not
prominent, defined by a thin groove (in the adult only), not diver-
gently sculptured. Front dorsal area rather sunken. Hinge-margin
broad ; teeth remarkably high, curved, and sharp.—Var. More
olive-coloured, peculiarly oblique; lunular region undefined.—
152 NUCULIDA.
The surface, on the removal of the epidermis, appears faintly ra-
diatingly striated, and the teeth, in the adult, are about twenty-
two on one side and eleven on the other; these strie are much
more manifest in the fry, which are provided, as usual, with a
much smaller number of teeth. AJl the specimens I have seen
named “ radiata, Dekay,” appear to be the young of this species,
but the furrow represented in his figure I have never descried (ex-
cept as an accident of growth) m any Nucula.
9. N. pautiuna, 4. Adams, f. 131, 132.—T. minuta, perob-
liqua, subovata, longitudine latitudinem paululum superante, valde
ineeqnilateralis, ventricosa, cute pallidé olivaced induta, undique
sublevigata. Hxtremitas lateris antici producti subattenuati ro-
tundata; latus posticum, acclivitate obliqué marginis ventralis
crenati et arcuati, inferné rotundato-excisum.—Minute, very ob-
lique, subovate, not quite so broad as long, ventricose, mode-
rately strong, very inequilateral, with a polished pale olive-coloured
epidermis, everywhere smoothish, yet with irregular concentric
incremental sulci: extremity of the produced and tapering an-
terior side rounded. Ventral margin crenated within, arched,
rising behind so as to obliquely round off the posterior corner.—
The same poor specimen has served Mr. Adams and myself for
description, and no definite characters can be derived from it. Its
beaks are eroded, but apparently much reflected: the lunular area
is not either decidedly prominent or clearly defined.
10. N. mirrauis, Hinds, f.144.—T. conoidalis, valida, ventri-
cosa (in exemplis adultis), levis, cute nitidissimé flava induta,
valde ineequilateralis. Hxtremitas antica rotundato-subcunei-

volute, eminentes. Area tuberculis transversim costellata. Lu-
nula haud prominens, concavé definita. Cartilago perobliqua.—
Longitudinally conoidal, ventricose when adult, with a polished
olivaceous-yellow epidermis, smooth. Anterior side greatly pro-
duced, its extremity rotundately subcuneiform ; ventral margin
arched, crenated, and rising behind so as to obliquely round off the
corner of the very short and nearly straight posterior side. Beaks
very acute, prominent, involute, not touching. Front dorsal region
barred across by short costellar tubercles that do not extend far
from the but little curved margin. Lunular region excavately
defined, not prominent : cartilage very oblique.—The typical form
of métralis is rather sharper at the beaks and more slender at the
anterior tip than in the more swollen gzda.

—Oblique, somewhat ovate, for the most part longer than broad,
very strong, evenly ventricose, clothed with an unpolished oliva-
ceous ash-coloured epidermis, grooved throughout ; grooves con-
centric, shelving, rather close. Ventral margin more or less
arcuated, crenated within, rising behind so as to rotundately cut
off the posterior corner. Grooves of the dorsal regions somewhat
obsolete ; their intervals densely marked with most minute diver-
gent striz ; lunular area much projecting. Beaks usually eroded.
—The cartilage-support protrudes greatly, and slants but little.
The teeth seem to average about sixteen and ten. Hven the dorsal
edges are crenulated, yet very delicately.

—It is said by Mr. Hinds, from whose works both figure and
description have been copied, to resemble the fossil Duchaste/ii, but
to differ by its striated lanule and uninterrupted lamellae.
14. N. eisum, Sowerby, f. 183.—T. minima, valde inzequila-
teralis, satis ventricosa, suboblique obovalis, cute pallidé olivacea

moderately ventricose, clothed with a rather glossy yet not polished
pale or cinereous-olive epidermis, rather obliquely oval. General
surface (the umbonal region excepted) densely wrinkled concen-
trically ; the corrugations raised, narrower than their intervals,
which (under a powerful lens) are, on the shorter side at least,
obscurely and finely lyrated across; when highly magnified, too,

both the front dorsal region and the lunular area are manifestly
though faintly and minutely marked with divergent strie. Hx-~
tremity of the produced anterior side rounded, its slope moderate.
Posterior side excessively short, not angulated below, but cut off,
as it were, in an oblique curve, by the much arcuated ventral
margin, which rises behind and is finely crenulated within. Lu-
nular area undefined, rather prominent.

radiantes, conspicue ; lunula inferné paululum eminentior, aliquan-
tumque angulariter planulata——Resembling eagua, but larger,
rather more tapering at the front extremity, and more rounded off
at the posterior ventral corner; the epidermis olivaceous ; the
grooves much closer, the radiating sculpture almost obsolete ; the
ventral margin less arcuated.—The type (a single individual) looks
like a large exigua, but is more compressed in proportion, and the
sulci are much closer on its nuclear portion than upon that shell.
The lunular area is neither impressed nor groove-defined.— Var. ?
NV. Paytensis, Adams, Proc. Zool. Soc. 1856, p. 51. Sculpture
sometimes obsolete on the umboes, the radiating lyre very dis-

oval, subventricose, with a dull dirty-yellow epidermis, everywhere
finely and somewhat arcuatedly ribbed : the front and hinder ribs,
which are rounded and narrower than their intervals, diverging
from each other at acute angles just behind the middle of the
shell ; a similar double divergence along the angular circumference
of the large and strongly impressed lunule, which latter is barred
across by much denser and smaller ribs. Anterior side produced,
somewhat tapering, and well rounded at its extremity ; its dorsal
slope rather slight, convex. Posterior side short, obliquely rec-
tangular below (in the adult). Ventral margin much arched in
its anterior ascent, more or less retuse (with age) just before the
end of its posterior ascent. No defined front dorsal area, but the
ribs are there denser and more numerous. Umboes rather pro-
minent ; beaks obliquely coiled, recurved.

everywhere concentrically costellated ; the interstitial sulci, except
perhaps on the undefined and inconspicuous dorsal areas, adorned

margin arcuated, entire, much and somewhat more straightly
rising behind, without posterior retusion. Beaks elevated, acute.
Lunule rather large, impressed, angularly defined, scarcely pouting.
Front dorsal region undefined. Cartilage not horizontal. Teeth
numerous.—D’Orbigny’s types of this species, which remind us
of nitida and convewa, are in sorry condition, without epidermis,

coarse incremental wrinkles in front, very inequilateral, not colour-
rayed, silvery-white within, simply rounded in front, rotundately
angulated below behind. Front dorsal edge convex, not remark-
ably sloping; hinder slope decided, straightish or subretuse,
sinuated by the profound concavity which defines the lunule.
Ventral margin arcuated, devoid of a sinus, not distinctly crenu-
ated within, yet most minutely so at the outer edge. Beaks
acute, not much elevated. Hinge-margin very broad : front teeth
very numerous; hinder ones very few: cartilage-pit narrow,
moderately slanting —I am indebted for the recognition of this

increase, with a polished pale greenish-olive epidermis. Anterior
extremity somewhat tapering, rounded, subemarginate above, front
dorsal slope convex and nearly horizontal. Posterior side long for
the genus, rotundately peaked, the peak subcentral, the somewhat
retuse dorsal slope not being abrupt as usual. Ventral margin

dermis, and faint but regular concentric wrinkles. Anterior ex-
tremity well rounded, front dorsal slope at first slight and convex.
Posterior side not short for the genus, hinder dorsal slope short,
not abrupt, but moderate, forming a rounded-off angle with the

rather pouting. Front dorsal area rather prominent, indistinctly
defined by a retusion.

the extremity (sometimes a little taper) ; its dorsal slope at first
straightish and nearly horizontal, then curved and moderately
sloping. Posterior side not short for the genus, subcentrally an-

which is at that stage smooth, with its lunule projecting in the
middle.*

margin entire, much arcuated, much rising behind. Beaks not
much projecting, yet conspicuous from their acuteness. Dorsal

between the typical ¢evwis and the boreal inflata. It is more produced lengthways,
less swollen, and usually greener than the latter; more trapezoidal, less arcuated
ventrally, and less rising and projecting at the lower posterior corner than the former.
Gould states that the manuscript name /wcida was attached to the specimens in the
Philadelphia Museum, and it is doubtful whether it should be regarded as a distinct
species, or as a mere varietal link with tnflata.

olivaceous-yellow to ashy-olive, smooth, yet with strongly marked
wrinkles of increase. Ventral margin entire, arcuated (the arch
very prominent just before the middle), rising somewhat more
straightly behind, so as to form a rounded-off obtuse angle with
the straightish or somewhat convex, rather abrupt posterior edge.
Front dorsal edge just at first straightish, and subhorizontal, then
much curved and descending. Posterior side very short, projec-
ting below. Dorsal areas wholly undefined ; lunular lips pouting.
Beaks very small, bent much forward, scarcely prominent, yet
conspicuous from their acuteness. Front hinge-margin sunken
internally. Teeth (in the adult) about fifteen and seven or sixteen
and eight ; the front ones scarcely vaulted, and near the extremity
compressed and seated on the inner edge. When not quite mature
a rounded off, very obtuse, angle is exhibited at the front dorsal
corner.

—Closely resembling éenwis, but more trapeziform, ventricose or
tumid, swollen and projecting at the umboes, usually only one-
fourth longer than broad; the epidermis ranging from dirty yel-
lowish-green to olive-brown. Ventral margin neither particularly
swollen before the middle, nor peculiarly rising behind. Posterior
side abruptly truncated, not projecting below. Lunular region
not strictly defined, but flattened at the circumference. Teeth
and hinge-margin not peculiar.

wrinkles of increase, which are very conspicuous below. Front
dorsal edge horizontal or rising, at first almost straight. Posterior
side almost excised, the hinder edge being almost perpendicular,
and the beaks, which, when not eroded, are acute and prominent,
being almost terminal. Ventral margin entire, subarcuated in
the middle, rising convexly at both ends. Lunular region much
and closely puckered, not strictly defined, yet concavely impressed
at its circuinference, and often marked with a few irregular radi-
ating incised lines. Front dorsal region expanded, disposed to
be indented.—The hinge appears to resemble that of fenuis, but
T have not examined any example which was uninjured in that
respect.

Area inconspicua.—Muinute, of a rather oblique abbreviated ovate-
triangular shape, ventricose, especially behind, clothed with a po-
lished olivaceous-green or olivaceous-yellow epidermis, concentri-
cally divided near the lower margin by broad shallow sulci into
flattened and somewhat shelving folds: the sulci here and there
perceptible (but not regular) on the umbonal region likewise.
Anterior extremity subangulately rounded below: posterior edge
almost perpendicular. Ventral margin entire, moderately arcuated,
rising behind so as to obliquely round off the posterior corner.
Beaks much elevated, usually eroded. Lunular region very pro-
minent, undefined (at most a little impressed at its margin),
coarsely wrinkled concentrically. Front dorsal area undefined.
Hinge-margin broad: cartilage not at all horizontal: teeth three
or four, and seven to ten.

come from the Philippines, and described from Mr. Cuming’s collection, must, I
suspect, have been lost ; for the three specimens named in that cabinet (f. 156) belong
to this species, and do not agree with their description. As Mr. Hinds omitted to
figure it, and the definition is wholly inadequate, the species may be regarded as too
uncertain to be retained.

very much at both ends, with a polished olivaceous epidermis that
ranges in tint from yellowish to cinereous, merely marked by
concentric wrinkles of increase, which in aged examples become
almost fold-like near the lower margin; devoid of umbonal ridge
or defined dorsal areas; marked, in the adult, with an almost
obsolete shallow broad indented ray behind, and a still fainter one
in front, at whose terminations the ventral margin is indented.
Extremity of the anterior side, which is rather, yet decidedly, the
shorter and narrower, retuse in the middle, subangularly rounded
above, obliquely rounded-off below : posterior end unsymmetrically
rounded. Dorsal slopes slight; front one plano-convyex, rather
the more decided: hinder one excavated for the ligament.
Ventral margin convex, more rising in front. Teeth extremely
fine, very numerous in front, scarcely any behind.—V/ar. drevior.

both ends, white under a polished yellowish olive-coloured epi-
dermis, devoid of umbonal ridge or defined dorsal areas, merely
marked with concentric wrinkles of increase, with the indented
rays and their terminal retusions almost imperceptible. Anterior
side very decidedly the longer, tapering to a symmetrically rounded
extremity: posterior extremity broadish, either rotundately sub-
biangulated or faintly rhomboidally rounded, the hinder end being
the more projecting. Front dorsal slope convex, moderately de-
cided; hinder one very slight and short, excavated for the liga-
ment. Ventral margin convex, curving up moderately in front.
Teeth rather fine, numerous behind, scarcely any in front.—The
most striking peculiarity is, that the anterior side, which is the
shorter in Worrisiz, is in this species the longer.

rhombic, more or less ventricose at the umbonal region, plano-
convex below it, obliquely divided into two areas by an umbonal
ridge, which parts off a posterior triangle that occupies a full
third of the entire surface, and is retuse in the middle, gaping
considerably at the hinder extremity: dull-white under a rather
dull yellowish ash-coloured fugacious epidermis, everywhere (the
dorsal areas excepted) roughened by rather distant concentric
raised striz, otherwise unsculptured. Anterior side scarcely three-
sevenths of the entire length, angulated above by the almost ho-
rizontal straightish dorsal edge, obliquely rounded below. Pos-
terior dorsal edge concavely elevated, and so produced that the
angulated upper termination projects far beyond the rounded hinder
ventral extremity : posterior edge incurved in the middle. Ventral
margin subparallel to the dorsal, convex or subarcuated, except
in the centre, where it is somewhat retuse. Lips of the escutcheon,
which is sublinear and plano-concave, pouting. Lunule very
narrow, if any.

+ As the engraving of this shell would hardly warrant this synonym, I subjoin a
description of D’Orbigny’s types, which now rest in our national Museum.—
N. semrornata, D’ Orb. Amér. Mérid. 624. pl. 84. f. 27, 28, 29.—Somewhat ob-
liquely ovate, much longer than broad, subventricose, with a shining ashy-olive epi-
dermis, concentrically traversed, towards the ventral margin, especially in front, by
somewhat wavy and rather irregular riblets, and adorned on the dorsal regions with
divergent curved close costellar strie ; otherwise unsculptured, yet with traces of the
radiating crenulz near the shorter end. Anterior side much produced, its tip well
rounded and slightly tapering; its dorsal edge convex. Posterior side extremely
short, its lower corner cut off by the oblique rise of the arched and finely crenulated
ventral margin. Posterior edge almost perpendicular, convex. Dorsal areas unde-
fined. +. San Blas, N. Patagonia.
MONOGRAPH OF THE GENUS
HARPA.
Char. Gen. Molluscum gasteropodum, testa subcanalifera, ventri-
cosa, ovali, costis longitudinalibus reflexis plus minusve regularibus
superné angulatis et acuminatis ornata; columella et spire parte
encaustis ; spiri brevi, coronata, apice mammillati; apertura
magna, anticé emarginata, labio externo reflexo, labio interno
tenuiter expanso; columella planulaté, anticé acuta, plica cana-
lifera costata ad dorsum reflexa.
The peculiar form and reflected ribs of the Harps distinguish
them from the shells of every other genus. In early stages of
growth the shells are striated, but the strie become obliterated
with age.
Species.
1. H. cosrata, Linn., f. 4, 5, 23.—H. inflata, rosea, super
costas albo-fasciaté, inter costas longitudinaliter striata, fusco
sparsim picta; costis crebris, superné vix trilobatis, ad angulum
acuté productis, tunc depressis, ad spiram in culmine plicato ele-
vatis ; apertura lata, flavida, labio interno incrassato, prope me-
dium castaneo maculato.—Linneus having described a species
resembling the “ Buccinum Harpa,’ but with crowded ribs, I
agree with the author of ‘Ipsa Linnei Conchylia’ that we may
conclude this shell, usually known as ZH. imperialis, to be the one
intended.
2. H. venrricosa, Lamés., f. 18-22, 25.—H. testa inflata,
subquadrata, inter costas longitudinaliter striata, strigis undulatis
acutis castaneis laqueata ; costis extantibus, fusco et albo fasciatis,
superne angulatis, plerumque laté reflexis, prope angulum subtri-
lobatis, acuté carinatis; spird anfractibus nigro encaustis ; apertur’
magna, superné subquadrata ; labio interno supra, medio et infra
fusco-nigrescente maculato.—This common but beautiful species
is distinguished from others by a certain squareness of outline in
VOL. III. U
170 HARPA.
the upper part of the whorls, and by the square and pointed flu-
tings of colour between the ribs. Fig. 21 is a close-ribbed variety
of this species, and in fig. 18 the markings have become irregular
and zebra-like. Tig. 25 represents the young shell.
3. H. nosis, Rumph.,f. 1, 2, 3.—H. testa subcylindrica, inter
costas levigati, maculis fuscis et rubris seriatim picta; costis pla-
nulatis, latis, pallidé roseis, transversé nigro-lineatis, ad angulum
acutis, infra crenulatis ; apertura mediocri, labio externo infra
crenulato.—Narrower and more cylindrical than H. ventricosa,
with no dividing points at the upper part of the ribs. Aperture
rather narrowing towards the base. The ribs and outer lip of the
aperture are crenulated at the lower part.
4. H. nasiium, Mart., f. 14-17, and 24.—H. testa solida,
obliqué ovali, superné declivi, carnea, rubro et fusco fasciata, inter
costas strigis undulatis laqueaté; costis crassis, decumbentibus,
plerumque ineequalibus, fasciatis, nonnunquam lineis nigris quasi-
articulatis ; spira elevata, encausta, declivi, levi; columella maculis
spadiceis magnis pict’.—Our distinct and almost specific variety,
f. 16, of which we have only seen two specimens, namely, Mr.
Juming’s and our own, is the same as figured in the third volume
of Martini, under the name H. nabliwm. Chemnitz afterwards
figured a bad specimen of the ordinary variety as “ Buccinum
Harpa antiquata.” There are many beautiful varieties of H. na-
blium (known as H. conoidalis) which pass into each other by in-
finite gradations. The slope of the spire, the more obliquely oval
form, and other points distinguish them all from /. ventricosa.
5. H. arricunaris, Lamh., f.9, 10, 11.—H. testa inflata,
ovali-ventricosi, inter costas grisescente pallidé maculis undulatis
ornati ; costis regularibus, pallidé fulvis, lineis latis transversis
duplicatis quasi articulatis ; aperturd magné, labio interno colore
castaneo nigricante laté infuso; spira breviuscula, acute coronata.
—This shell is hghter, more ventricose, and less oblique than any
of the varieties of H. nablium ; it is of a greyish colour, the spire
is shorter, less enamelled, and more sharply crowned with rib-
points. ‘The markings between the ribs are pale, while those upon
them are very strong, and the colour in front of the shell is uni-
formly spread, instead of being in patches, as in the last species.
6. H. cancetnata, Chemn., f. 26.—H. testa parva, pallida,
transversé lineis elevatis duplicatim striati; costis distantibus
tenuibus superné acutis ; spira brevi, apice elevato acuto.—<As the
young of all the species of Harpa are spirally striated, I am not
certain of this being a distinct species, but more than half suspect
HARPA. wal
it may be the young of H. articularis, in very early whorls of
which may be observed a similar duplicate striation. I am glad
of an opportunity of figuring this unique specimen in Mr. Hanley’s
collection, which might have been the very original of Chemnitz’s
figure.
7. H. Rivortana, Lesson, f. 12, 18.—H. testi subangulata,
paululum turbinata, grised, inter costas minuté fasciatim et undu-
Jatim fusco strigaté ; costis decumbentibus, angustis, interruptim
longitudinaliter nigro-lineatis, superné triangulatis, ad angulum
supremum acuminatis, anticé undulatim crenatis; spira brevi, an-
fractu ultimo solum encausto.—This species, /Z. crenata of Swain-
son, Is unquestionably distinct from H. rosea, which, besides the
difference in colour, is not at all angular or turbinated above, and
has the spire much more produced.
8. H. roswa, AZein, f. 6, 7, 8.—H. testa ovali, subangustata,
rose, inter costas minute fasciatim et undulatim fusco strigata et
maculis magnis rubro pict; costis decumbentibus, angustis, in-
terruptim longitudinaliter fusco-lineatis, superné subspinosis, anticé
undulatim crenulatis ; spira elevata, anfractibus rotundis ; labio in-
terno tenuissimé encausto.—More oval than H. Rivoliana (Cre-
nata, Sw.) and more rounded at the upper part of the whorls and
ribs. The pinky tint and rosy patches between the ribs are
constant, although the dark bands in var. f. 6 give a rich purplish
aspect to the shell.
9. H. minor, Rumph., Mart., f. 27, 28, 29.—H. testA angusta,
fulva seu pallidé grisea, inter costas fusco seu purpureo undulatim
minute strigata; costis plerumque inequalibus, superné acute
nodosis, transverse creberrimé fusco-lineatis ; spird elevata, anfracti-
bus coronatis ;—variat costis crebris.—The more volutiform variety
with numerous ribs is regarded as distinct by some collectors, but
the varieties are so numerous and the gradations so subtle that I
cannot by any means adopt the separation. I am even doubtful
as to the propriety of separating the next.
10. H. crassa, Mérch, f. 30, 31.—H. testa H. minori simili,
sed crassiore ; costis superné angulatis.—The only tangible dif-
ference between this and the last is the angle or shoulder formed
on the upper part of the ribs. It is rather conventionally than
scientifically that I should adopt a distinct name for this variety
or possibly “ incipient species.”
ll. H. cracitis, Brod., f. 32, 33.—H. testé H. minori simili,
sed tenuiore, pallida, elongata, transversé minutissimé striat4, pos-
ticé angulata ; spird vix coronaté.—This probable species departs
172 HARPA.
from the typical form of /7. minor in the opposite direction to that
of H. crassa, being elongated, thin, and narrow, with the aperture
slightly contracted towards the spire and widened in front.
12. H. virernatts, J. Gray, f. 34, 35.—H. testa alba, 77. crass
simili, sed spird breviore et magis declivi ; costis obtusis, superné
angulatis, interstitiis unicostatis—I am indebted for a drawing of
this unique shell, which I have seen, to the kindness of J. Gray,
Ksq., of Glasgow, who has had it in his collection for some years.
It may quite possibly prove a variety of ZZ. crassa, but the penulti-
mate whorl is less elevated, and an intercostal riblet, which occurs
accidentally and irregularly in some species, assumes a rather re-
gular and formal aspect in the more advanced part of this interest-
ing shell.

MONOGRAPH OF THE GENUS
GALEOMMA, Turton.
Genus.—Molluscum acephalum, bimusculosum ; testi bivalvi,
transversim ovata, terminibus subacutis omnino divaricatim striata,
striis dorsalibus divaricatim adscendentibus; valvis ad marginem
ventralem laté hiantibus ; cardine edentulo seu dentibus utraque
valva duobus parvis, quorum und nonnunquam duplicaté; lga-
mento parvo, lineari, interno; pall impressione integra.
In distinguishing between the species of this genus and those of
Scrntitta, | have thought the best guide would be the presence
of sculpture in the former and its absence in the latter, and have
therefore displaced the four species included by M. Deshayes in
his division of Galeomma, described as “lisses et brillantes a
ouverture médiocre,” namely, ambigua, splendida, polita, and Lay-
ardi. The Galeomme lie in mud and sand under stones, with
their valves spread open.
In the following descriptions, I have chosen rather to attend to
comparative characters than to repeat these which are more pos?-
five. I adopt this method in concurrence with the following sen-
iments expressed by Buffon :—
“Tt is only by comparing that we can judge, and our know-
ledge turns entirely on the relation that things bear to those which
resemble them.”

Obs. The pointed ends and wide hiatus of this white British shell
are wellknown. The sculpture consists of beaded strie diverging
in pairs and rising upwards towards the dorsal edge.

2. G. macrocuisma (f.7, 8), Desh.—Testa pallidé fulvaé, quam
G. Turtoni breviore ; terminis magis obtusis; valvis medio coare-
tatis; dentibus nullis. Ods. This is the Philippine analogue of
our British species, but shorter and more truncated in form.
3. G. arcentea (f. 13, 14), Deskh.—TestA mimuté striata, quam
G. Turtoni magis compressi et ad terminos truncata, dentibus
minutis; intus quasi-argented. Ods. Much flattened and more
truncated at the ends than G. Turton, with the inside shining
like silver, and the outside very minutely striated.
4, G. rormosa (f. 11), Dess.—Testa ovali, oblonga, aurantio-
fulva, subcompressd ; terminis acutis; striis medio evamidis, ad
marginem dorsalem adscendentibus ; dentibus parvis. Ods. This
species also approaches the typical form, but the strise are very
faint on the body of the shell, which is of an orange-brown tint.
5. G. iviata (f. 5, 6), Desh.—Testd fulva, inflata ; terminis
rotundatis, medio coarctato ; latere postico majore, striis minutis
medio subevanidis ; dentibus parvis.
6. G. paucistriata (f. 9), Desh.—Testd albidd, subinflata,
subovali, medio coarctata; terminis obtusis, stris numerosis di-
vergentibus, ad marginem dorsalem adscendentibus. Ods, The
sculpture is regular but much more close than in G. Turtoni. It
is a thin shell, obtuse at the edges.
7. G.inpecora (f. 15), Desh.—Testa albida, tenui, subinflata ;
striis distantibus, subevanidis. Ods. This is like the preceding,
but is rather more equilateral, the sculpture far less distinct, and
the valves not so much inflated.
8. G. aneusra (f. 10), Desh.—Testi quam G. paucicostata
angustiore. Oés. In sculpture similar to G. paucicostata, but
more straight and narrow.
9. G. cunoroteuca (f. 12), Desh.—Testa pallidé aurantia,
ovali, medio coarctata; hiatu angusto; striis subevanidis. Oés.
The melon tint and general proportions of this species bring it
very near to Secntilla ambigua, but on careful examination, it 1s
found to be striated.
MONOGRAPH OF THE GENUS
SCINTILLA.
Genus.—Molluscum acephalum, bimusculosum ; test bivalvi,
polita, transversim subovataé ; terminis rotundis seu subtruncatis ;
margine ventrali clauso vel paululum hiante, margine dorsali non-
nunquam hiante ; cardine dentibus utrique valvd duobus, quorum
postico nonnunquam duplicato, ligamento parvo, lineari, interno ;
pallii impressione integra. Ods. Very few of the species gape in
front, and none so widely as in the true Galeomme. Some of
them are open at the ends and dorsal margin. When living, the
valves lie spread open, with the mantle turned back over the edges
and often a great part of the surface, which probably gives them
the brilliant polish by which they are distinguished from Galeomme.
Species of Scintilla.
Plates 234, 235.
Sect. I. Species with an hiatus in the ventral margin.
1. Sc. Layarot (f. 20), Desh.—Testa tenuissima, alba, com-
pressi, subequilatera ; terminis snbtruncatis ; margine ventrali
hiante. Ods. It is like a true Galeomma, excepting that it has no
sculpture.
2. Sc. sprenpipa (f. 14, 15).—Testd politissima, quam Se.
Layardi altiore ; latere antico subtruncato. O43. Much wider from
apex to base than Se. Layard’, which otherwise it resembles.
3. Sc. pourra (f. 19), Desh.—Testi alba, compressi, tenui,

opening is not large.
5. Sc. auranwraca (f. 5), Desh.—Testa aurantid, quam Se. am-
digua magis elongata ; hiatu parvo. Ods. The narrowness of this
shell is hardly sufficient to distinguish it from the preceding.
The hiatus is, however, smaller.
6. Sc. patiiputa (f. 6), Desh.—Testd pallidi, Se. ambigue
simili, sed margine ventrali vix hiante. Os. The very small ven-

substriata, subinflata, latere postico majore, latere antico obliqué
subtruncato; margine ventrali subcontracto. Ods. Like Sc.
Adamsii, but more inflated, slightly contracted at the ventral edge,
and faintly striated or undulated concentrically on the surface.
9. Sc. rospa (f. 11), Dest.—Testa rosea, polita, inflata, clausa,
oblonga; latere postico longiore et latiore, latere antico parvo,
declivi. Obs. Of a beautiful rose tint; this shell is also remark-
able for the smallness of its anterior as compared with its poste-
rior side.
10. Sc. puptca (f. 12), Desh.—Testi Se. rosee@ simili, sed
latere antico subquadrato; margine ventrali paululum aperto.
Obs. More square and truncated than Se. rosea, with a very shght
opening in the ventral margin.
11. Se. Ruecruzrana (f. 13). Desh.—Testd tenui, rosei-purpu-
rescente, oblonga, latere antico truncato ; margine ventrali recto,
clauso. Obs. A thinner and more purple shell, more straight at
the ventral margin and truncated on the anterior side than Se.
pudica.

Ods. A more opaque-white shell than Se. Oweniz, with the dorsal
margin more sloping on the posterior, and more elevated on the
anterior side.
15. Sc. rapa (f. 17), Desh.—Testa lacted, ovali, inflata, postice
rotundata, anticé vix truncata. Ods. More inflated and rounded
than the preceding, not so truncated at the anterior side.
16. Sc. vorutosa (f. 21), Desh.—Testa pallidissimé roseé,
compressa, oblonga, concentricé vix undulata; latere antico breviore,
subtruncato. Os. Flatter and more straight than the preceding
species.
17. Sc. canpipa (f. 33), Desh.—Testd lacted, ovali, clausa,
subinflata ; margine ventrali subrotundo; latere postico subde-
clivi, latere antico brevi, declivi. Ods. A milk-white oval shell,
closed all round.
18. Sc. renuts (f. 34), Desh.—Testé quam Se. candida lon-
giore, rectiuscula, tenuiore, anticeé magis truncata. Ods. Slightly
straighter, longer, thinner, and more truncated anteriorly than
Se. candida.
19. Sc. Juxesn (f. 42, 43), Desh.—Testa ovali-oblonga, alba,
subdiaphana, fasctis opacioribus, subzquilateré, utrinque sub-

Obs. This fine shell is shghtly open at the extremities and dorsal
margin.

alba, partim minutissimé granulati, clausi; margine undulatim
crenulato; cardine laminato; latere antico paululum minore.
178 SCINTILLA.
Obs. A very curious, white, oval shell, which, although to the eye
smooth, is minutely granulated and striated near the margin, and
has its inner edges crenulated or undulated in a singular manner.
21. Sc. scrntinuans (f. 44), Desh.—Testi ovali-subquadrata,
nitente, clausi, apice et medio semipellucida, cceruled, prope mar-
ginem opaci, crassiore, lutei; latere antico breviore; margine
dorsali utrinque declivi. Ods. Bluish and half-transparent at the

MONOGRAPH OF THE FAMILY
FISSURELLID A.
Genus FISSURELLA.
Char. Gen. Molluscum gasteropodum ; test externa, patelle-
formi, dorsum tegente, «tate ad apicem perforata, cicatrice mus-
culari, submarginali, crescentiformi, antice interrupta.
In the very earliest stage of growth, the shell in all Fissuredlide
is subspiral with the margin entire. Then a passage is made for
the anal tube by a notch or sinus in the margin. In Seutus, or
Parmophorus, the sinus continues slightly marked to the margin
of the adult shell. In Hmarginula it is continued in the form of
a distinct marginal notch. In Cemoria, the margin closes round
the notch, leaving a hole near the apex, which is left entire; in
Rimula, the hole is left half-way towards the margin; and in
Fissurella and the four following genera the spiral nucleus alto-
gether disappears, leaving a hole at the apex in its place more
or less enlarged by absorption. I adopt the proposed separation
from Fissurella,—lst. Of Fissurellidea, because the shell is
covered by the animal ; 2nd. Of C/ypidelia, because it is peculiar
in form and only covers part of the animal; 3rd. Of Macrochisma
for the last two reasons, besides the peculiar form and position of
the foramen ; and 4th. Of Pupil/ea, on account of the insertional
ridge of the margin. I cannot agree to separate the larger num-
ber of remaining species under the generic name of Lucapina as
proposed, because the crenulated margin, the forward inclination
of the apex, the truncated internal callus and slight differences in
the fringes of the animal’s mantle, are so much questions of degree
that it 1s practically impossible to divide the species so as to pre-
serve consistency in all the characters.
184 FISSURELLID®.
Species of Fissurella.
Sect. I. Shells with distinct internal marginal border.
1. nrera (f. 14), Lesson.—Testé magna, elevata, ovali, ni-
grescente, sublievigata, striis evanidis radiata, foramine albo, mar-
ginata, subcentrali, antice depressa, intis alb&’; margine ceruleo,
subcrenulato, ad apicem callo interno laté crenulato. Ods. A
broad, smooth, nearly oval species, of a dark inky colour.
9
2. tmBarTa (f. 25, 24), Sowb.—Ovali, conicd, anticé vix at-
tenuata, levi, radiis rubris vel spadiceis latis radiata; aperture
margine intis violaceo; foramine oblongo, subcentrali, intis vix
calloso. Oés. Not so elevated as the preceding, and very brightly
rayed with purple bands.
3. Bripeusy (f. 21, 22, 34), Reeve.—Crassi, depressd, ob-
onga, sublevigati fulvo-grisescente, anticé attenuata, intus alba ;
margine lato, purpureo, levi; foramine ovali paululum infra
medium posito, marginibus elevatis, intts calloso. Ods. Rather
flat, attenuated in front, and of a greyish-brown colour. A very
curious specimen in Mr. Cuming’s collection is represented (f. 22),
in which the foramen has been completely filled up with callus,
which usually surrounds it. The same phenomenon has very nearly
occurred with the specimen of 7. maxima represented at f. 9. In
both cases, the anal tube must have been bent round so as to pass
under the side of the basal aperture. TF. 34 is a narrower variety.
4. FULVESCENS (f. 386), Sowb.—-F. Bridgesii simili, sed flavida,
rubro radiaté; termimibus paululum elevatis. Ods. Very like the
preceding, but yellow, with purplish-red rays, and the ends a
little elevated.
5. erispa (f. 85), Reeve.—F. Bridgesii simi, sed magis
ovali et elevaté ; foramine magis centrali. Ods. This may be an
abnormal form of Bridgesii, more oval and elevated, with the
foramen more central.
6. crassa (f. 16, 17), Zamb.—Oblonga, crassi, depressa, oli-
vaceo-fulva, obscuré radiata, leevigata concentricé et ad marginem
undulata ; intis callosd, radiatim rugat&; area mediana rosea ;
foramine elongato, in medium contracto, intts validé calloso.
Obs. A peculiarly flattened oblong species, thickened within.
7. putcura (f. 31), Sows.—Ovali, levi, depressa, anticé
paululum attenuata, fulvo-grisescente, prope medium fasciis ra-
diataé et maculis rubris mgris et albis variegata; foramine sub-
centrali, oblongo medio contracto. Oés. Shorter than /. Bridgesii,
with delicately variegated rays.
FISSURELLID. 185
8. Beta (f. 25), Ave.—Ovali, radiatim leviter striata, anticé
contracta, subacuminata, concentricé griseo fasciata, fasciis pur-
pureis radiata, inthis albA; margine purpareo maculato, angusto ;
foramine oblongo, vix infra medium posito. Oés. This pretty
species is rather pointed in front, it has purple rays and almost
obsolete striz.
9. LaTIMARGINATA (f.6, 7,12), Soed.—Subovali, anticé attenuata,
fulvo-purpureo radiatim striati, intis alba; margine purpureo
lato, vix crenato ; foramine subcentrali. Ods. In form resembling
Bridgesii and hella, but radiately striated, and having a remark-
ably broad purple border. I. 12 represents a narrower form.
10. Brraprata (f. 1, 2, 3), Frembley.—Subovali, depressa,
anticé attenuata, subacuminata, radiatim striata, cinerea, radiis
binis albis lateralibus apice decurrente ; intis albi; margine sub-
purpureo lato; foramime subcentrali, medio contracto. Ods. In
form resembling /”. 4ed/a, but of a uniform colour, excepting the
white rays, which are lost in adult specimens, and having a broad
margin instead of a narrow one. Fig. 3 represents /. galericulum,
which is only a contracted form of this species.
11. Prruviana (f. 38—41), Zamb.—Plus minusve ovata, pos-
tice subcontracti, plerumque elevata, purpureo plus minusve
radiaté, striis elevatis graniferis radiati; foramine subcentrali,
rotundo ; marginibus elevatis. Ods. Amidst the variations to
which this species is subject, there is a strong tendency to purple
radiation, granular striation, and a form elevated near the apex.
F. 39 is abnormally conical. After some doubt and consideration,
T have concluded that the more oblong and flattened form may be
distinguished as follows.
12. arrinis (f. 42, 179), Gray, Sowb., Con. Ill.—F’. Peruviane
similis, sed magis oblonga et depressd. Ods. This less conical
and more oblong form is separated to avoid the extreme inconve-
nience of including opposite characters under the same name, al-
though the gradations are perplexing.
13. ciypgus (f. 63).—Ovali, depressa, costellis subnoduliferis
radiata, lutea rufescente, fasciis albis duabus lateralibus et fasctis
16 mgrescentibus interruptim sagittatis radiatim picta, intis alba;
margine luteo maculis purpureis interrupto ; foramine ovali, supra
medium posito. Ods. In colouring and marginal character so much
like var. f. 40 of F. Peruviana, that it might be almost taken for
a specimen of that species unnaturally depressed.
186 FISSURELLID.
14. muricara (f. 68), Rve.—F. Peruviane simili, sed cos-
tellis nonnullis majoribus imbricatis, colore purpureo-nigrescente
prope foramen annulatd. Ods. I am strongly inclined to believe
this another variety of Perwviana, with some of the ribs enlarged
and imbricated.
15. Mexicana (f. 26, 27, 28, 78), Sowb.—Oblongi, depressi,
tenui, radiatim striaté, rubra, purpureo radiat&i seu nigra, intis
albi; margine purpureo vel nigro, angusto; foramine magno,
albo marginato. Os. Oblong, striated thin shell, either black or
beautifully rayed with purple or red. Foramen large, edged with
white.
16. Puiniperana (f. 30), Rve-—Mevicane similis, sed costellis
nonuullis extantibus subimbricatis; foramine magis angusto et con-
tracto. Ods. It is more imbricated than /. Mexicana, with more con-
tracted fissure.
17. arrara (f. 71), Rve.—F. Philippiane simili, sed parva,
sublevigata, late marginaté; costellis nonnullis prope marginem
undulatim imbricatis. Obs. It is hike #. Philippiana, but with a
comparatively smooth surface, stellated with white near the apex,
with some of the ribs imbricated with peculiar undulations near
the margin.
18. exquisita (f. 32, 128), Ave.—Oblonga, subdepressi, an-
ticé paululum attenuata, tenui, alba’, griseo concinné 18-radiata-
radiatim eequaliter costellaté ; costellis subnoduliferis ; foramine
oblongo; margine utrinque bilobato. Ods. Neatly rayed with
eighteen grey bands, and sculptured with numerous equal, granu-
lated, fine ribs.
19. orrens (f. 19, 20), Sowd.—Oblonga, depress, solida,
leviter radiatim striaté, luted seu grisea concentricé fasciata, fasciis
griseis vel rubris radiaté; intts albo margine griseo, angusto.
Obs. A much more solid and broader shell than /. Mexicana.
20. prora (10, 11, 35), Gmel., Lamb.—Ovali, subconica, so-
lida, subleevigata, costellis leviter granulatis, luted vel nigrescente,
purpureo vel nigro radiatim fasciata, tus albo, griseo laté mar-
ginato ; foramine oblongo, intis calloso, circumscripto. OZs. One
of the larger species with broad margin of an inky colour, or
whitish with inky rays. J. Darwini (f. 35), Rve., seems to me
only a variety of this.
21. poryGona (f. 187,177), Sowd., G. B. 2.—Ovali, angulata,
FISSURELLIDE. 187
anticé attenuata, alba, purpureo interruptim radiata, striis scabris
numerosis et costellis catenzeformibus rarioribus extantibus radiata,
intus alba; margine maculato. Ods. This beautiful shell is dis-
tinguished by scabrous striz with noduliferous or chain-like ribs
at intervals.
22. maxima (f. 8, 9), Sowd.—Magna, ovali, anticé paululum
attenuata, crass4, costis levibus undulatim nodosis radiata, fulva,
purpureo radiatim fasciaté ; margine undulatim crenulato, intus
albo, calloso; foramine ovali, centrali, intts calloso. Os. A large
well-known shell, broadly rayed with purple bands and thick undu-
lated nibs. F. 9 is a singular specimen, in which the fissure is
nearly closed by shelly deposit. See #. Bridgesii for a case of
entire closure.
23. concrnna (f. 4, 178, 206), Philippi.—P. mazime simili,
sed multo magis angusté; costis nonnunquam magis nodosis.
Obs. Very probably a variety of F. maxima, but so constantly
narrower in all stages of growth as perhaps to merit distinction.
The smaller specimens are much more rugose, and the surface un-
dulated. M. Hanley’s larger specimen is as smooth as 7. maxima.
T cannot doubt the identity of Mr. Reeve’s Hondurasensis.
24. sretiava (f. 82), Rve.—F. mazime@ simili sed parva;
radiis prope apicem interruptis et sagittatis. Obs. Although this
little shell appears full grown, it presents a very close miniature re-
semblance to its gigantic ally. Near the apex, the purple rays
are interrupted and arrow-headed.
25. Cumrnett (f. 5, 182), Rve—Lata, ovali, depressd, anticé
paulo attenuata, purpureo, vel rubro radiata, lineis elevatis scabris
costellata, intts alba, purpureo laté marginaté; foramine ovali.
Obs. Broad, depressed, brownish, purple or purple-rayed, with
scabrous strie; a very broad purple margin. The young speci-
men, f. 132, is Mr. Hanley’s.
26. tava (f. 13), Sow.—Lateé ovali, elevata, luted, fasciis pur-
pureis et costellis moniliferis radiaté; foramine ovali. Ods. A
much more elevated shell than the last, with beaded riblets.
27. costata (f. 15, 205), Lesson.—Latissima, pallidé fulva

probably belong to either. I. 205 is a remarkably wide and nodu-
lose specimen procured during progress.
Sect. II. Without defined internal border.
28. niGro-puncrata (f. 33).—Crassi, conicd, subrotunda, ir-
regulari sordidé fulva, costellis nigris moniliferis irregularibus
alternatim minoribus radiata, intis viridi, prope apicem incrassata,
ad marginem aperture crenulaté, nigro punctati; foramine magno,
medio contracto. Ods. A rough, rather round, irregular shell,
green within and radiated without by black beaded ribs.
29. coarcrata (f.60), King.—P.nigro-punctate simili, sed magis
levigati ; foramime medio yalidé contracto. Ods. It is doubtful
whether the contraction of the aperture be not merely accidental ;
and varieties of the last species occur which are almost as smooth as
this; but, although I should have been unwilling to found a species
from so worn a specimen, I am willing to adopt it as founded
by others.
30. virescens (f. 87), Sows.—Ovali-rotunda, conicd, viride-
scens, costis rotundis alternatim majoribus radiata, intus viridi ;
margine crenulato ; foramine subovali, medio angusto. Obs.
Green, with alternately large and small rounded ribs.
31. monitirera (f.175), Sowd., G. B. 2.—Ovali, conica, rugosa,
costellis alternatim nigris et fulvis moniliferis radiata ; foramine
magno, ovali, medio subangusto, intus calloso, rubro lineato.
Obs. This must have been a beautiful shell when in living con-
dition, the alternate ribs consisting of minute regular black beads.
A pink line defines the inner callus. The worn but still pretty
specimen is in M. Hanley’s collection.
32. ata (f. 88, 89), Carpenter.—Ovali, tenui, conicd, cos-
tellis irregulariter noduliferis alternatim minoribus nonnunquam
nigrescentibus radiat&é; foramine oblongo, medio subangusto,
paulo supra medium posito. Os. Were it not a rather thin
white shell, it might be taken for a variety of /. nzgropunctata; but
the ribs are more regularly alternate, and the nodules upon them
are larger and longer. The fissure is placed a little towards the
anterior.
33. ALABASTRITES (f. 43, 44), Ave.—Crassd, ovali, alba, rugosa,
costis crassis, ineequalibus, irregulariter nodosis ; foramine oblongo,
magno, medio contracto. Ods. A coarsely-ribbed, thick, white shell.
34. Guaucorts (f. 45), Rve—Subviridi, /. alabastriti simili
sed foramine parvo, ceruleo marginato. Ods. The smallness of
FISSURELLID®. 189
the foramen, which is bordered with blue, presents a striking pecu-
liarity in this shell, which otherwise resembles /. aladastrites.
35. novosa (f. 59), Born.—Ovali-subrotunda, elevata, pallida,
lateribus convexis, costis elevatis nodulosmagnos ferentibus radiata ;
foramine subcentrali, ovali, medio contracto. Ods. The well-
known species with large nodules on the ribs.
36. Humpureyti (f. 61), Rve.—F. nodose simili, sed costis no-
duliferis, minoribus, alternatim minimis, interstitiis ccruleis.
Obts. The nodulous nbs much less prominent and alternating in
size.
37. conorpes (f.51), Rve.—Ovali, crassa, rugos4, irregulariter
costata, alb4, intus viridi; foramine oval, nigro marginato, Ods. A
conical white species, green within, and having a black ring round
the fissure.
38. oprusa (f. 75, 76), Sowb.—Ovali, convexa, leviter costatia,
costis albis distantibus et interstitiis striatis roseis vel rubris radi-
até; intus viridi; foramine parvo, paulo supra medium posito.
Obs. Has the sides convex like Humphreyi, with distant white ribs
and red striated interstices; the inside is green, and the foramen
small.
39. Barpapensis (f. 49, 144-146), Gmel.— Ovali, posticé
paululum attenuata, alba vel pallidé fulva, fasciis nigris vel rubris
plus minusve interruptis variegata, costis crassis imbricatis rugosis
inequalibus radiata; inttis viridi; margine laqueato ; foramine paulo
supra medium posito, parvo, subquadrato. Os. The ribs on this
species are irregular and unequal, imbricated with little exfolia-
tions, colouring and markings variable, but always green inside.
F. editia, Rwe. (f. 49), is slightly more depressed, attenuated in
front, and characterized by smaller ribs.
40. naprata (f. 48, 50), Lamk., Sowb.—Quam PF. Barbadensis
mavis depress&, postice attenuata; costis minimé imbricatis. Ods.
Variety f. 49 of Baréadensis approaches this species in the form,
which is more depressed and attenuated in front; but in this
species the ribs are not imbricated. It is better to adopt the
late G. B. Sowerby’s identification of this Lamarckian species, with
the description of which it agrees pretty accurately, than to give
it a new name, as Mr. Reeve has done.
41. rugosa (f. 46, 47), Sows.—Ovali, validé compressa, posticé
attenuata, costis rugosis ineequalibus quarum tribus anticis maximis
VOL. Ill. Z
190 FISSURELLID&.
radiata, pallideé fulva albé et rubra radiatim fasciata ; intis viridi;
foramine paulo supra medium posito, subquadrato. Ods. Very
much depressed, with three front ribs largely developed.
42. aspERELLa (f. 56), Sows. —F. rugose simili, sed costis multo
magis depressis et minutis. O4s. In this species the three promi-
nent ribs are depressed, although shown prominently by being left
white. The shell is more finely striated.
43. microTREMA (f. 54, 55), Sows.—Ovali, anticé paulo at-
tenuatd, subangulataé, compressi, castaneo rubescente vel olivacea,
costis minutis irregularibus scabris; intus viridi; margine crenu-
lato ; foramine parvo, nigro-marginato, supra medium posito, ntis
callos so; callo albo, nigro- marginato. Obs. Like F. asperella, but
with the minute ribs imbricated ; ; Inside green, foramen very small.
44. Navatensts (f.69), Avauss.—Ovali-oblonga, subelevata,
anticé angustata, alba fusco-nigrescente variegata, costis rugosis in-
zqualibus rotundis radiat&é; intis alba; foramine oblongo, magno,
tripartito. Ods. Rather narrow in front, with irregular rounded
ribs; a long, divided foramen.
45. NUBECULA (f. 73). Linné.—Ovali, anticé angustatd et
magis quam postice elevatd, alba, fusco- ona dl alti, radiis
snbyiridibus griseo maculatis radiatim fasciaté, costis subplanulatis
interstriatis radiaté; intis albo- viridescente ; foramine oblongo,
medio paulum contracto. Ods. The specimen, figured from Mr.
Cuming’s collection agrees very well with the description in the
‘Systema’ with which it has been identified. It is more elevated than
the following, with a much more elongated foramen.
46. noska (f. 91, 92, 150), Lamk.—F. nubecule simili, sed
magis depress, costis nonnullis exstantibus, rubro radiata et varie-
gata ; intis viridi; foramine ovali, brevi.
47. osrrina (f. 84), Zve.—Ovali depress, purpurea, albo
prope apicem radiata, costellis parvis striatis depressis radiata ;
jntis viridi; foramine oblongo. Ods. This obscure little shell is
oval depressed, finely ribbed, green within.
48. muraBiuis (f. 70, 74, 79, 98), Sowb.—Ovali, anticé an-
gustata, lateribus subeompresssis, grisea vel rose, irregulariter
planulatim costata et striata, intts albi; callo interno circum-
scripto ; foramine oval, mediG coarctato. Ods. The front of this
shell is narrowed by the compression of the sides; its surface is
radiated by impressed strie dividing the flattened unequal ribs,
FISSURELLID®. 191
and lighter ones upon them. Var. f. 74 is the F. éncarnata of
Krauss, and is the original of the ‘ Conchological Illustrations.’
49. catittus (f. 81), Rve.—Parva, FP. mutabili simili, sed
minute «qualiter striata, fasciis latis rubris prope apicem radiata.
Obs. More evenly striated than F. mufadilis, and radiated with
brown bands, which near the margin are suddenly interrupted.
50. rentata (f. 77), Sows. G. B. 2.—F. mutabili simili,
sed levigata, fasciis fuscis duplicatis 11 radiata. Oés. In form
resembling the preceding, but without stri#, and marked by
eleven pairs of brown rays.
51. nora (f. 72), Rve.—Ovalis, anticé angustaté et depressa,
fulva, fasciis fuscis et costis depressis radiata ; foramine ovali, sub-
centrali, anticé subinclinato. Ods. A pretty little brown-rayed
species, with ribs divided by impressed striae. The fore part is
narrow and depressed.
52. macrotremMa (f. 86, 90), Sowé.—Ovali, crassa, lateribus
convexiusculis, subviridi, purpureo-nigrescente radiata vel omnino
picta, costis depressis striatis ineequalibus subrotundis radiata ;
intis viridi, propé apicem plurimum tinctéi; foramine magno,
profundo, medio validé contracto.
53. Lonatrissa (f. 66), Sowd. G. B. 2.—F. macrotreme simi-
li sed vividé rubro radiata ; foramine eclongato, angusto, tripartito;
intiis callo roseo-marginato. Ods. The fissure of this brightly-
rayed shell is so peculiarly long and narrow as to distinguish it
from the preceding, which it otherwise resembles.
54. opscura (f. 80), Sowd.—Ovali depress, irregulariter
convexA, subviridi, et purpurea lineis roseis striata, costis distan-
tibus inzequalibus subnodosis radiat&é; ints viridi; foramine
oblongo, viridi, medio contracto. O%s. Distinguished from the
two preceding by the distant compressed ribs, which are some-
what nodulous.
55. nicrocinera (f. 64, 65), Carpenter.—Ovali, convexa, vix
anticé attenuata, impresso-striaté, fasciculis lmearum nigrarum
radiatim fasciatd, interstitiis nigro-punctatis; intis alba; callo
nigro-marginato; aperture margine acuté denticulato interstitiis
nigris. O%s. A pretty little shell, striated with depressed lines,
and radiated by black lines in bunches of three. The margin is
sharply denticulated with black interstices. The internal callus is
defined by a sharp black line.
192 FISSURELLID&.
56. Tenezrosa (f. 67), Sows. G. B. 2.—F. nigrocinete simili,
sed magis rotunda; radiis nigris, nebulosis; costellis vix elevatis, sub-
nodosis; margine aperturee vix crenulato. Os. A more rounded
shell, more loosely ribbed and cloudily black-rayed than the pre-
ceding, only slightly crenulated at the margin of the aperture.
57. Batanorpss (f. 94), ARve.—Ovali, conica, subviridi, fusco
vel olivaceo radiatim fasciatd, costellis depressis subevanidis radi-
até; intus viridi; margine leviter crenulato. Ods. This shell re-
sembles in general appearance a smooth variety of Patella vulgata,
plus the fissure.
58. nimBosa (f. 136), Linn.— Ovali, anticé subattenuata,
conic, elevatd, subviridi, inter costas lineis mgris et viridibus radi-
atim fasciata; costellis albis, subnodulosis; foramine ovali, pro-
fundo, medio contracto; intis viridi; margine crenulato-nigro,
punctato.
59. vorcano (f. 87), Ave.—Ovali, conic’, prope foramen
elevatd, costellis seabris rotundis inequalibus radiata, fasciculis
rubris nigro-punctatis radiatim fasciat&é; foramine alto; intis
alba’; margine crenato, maculato.
Margin denticulated. Apex leaning forward. (Gen. “ Lucapina.”)
60. nuctecra (f. 1389), Desh.—Lati, prope margines depressa,
prope apicem elevata, anticé subattenuaté, postice dilatata, lateri-
bus medio areuatis concentricé undulatim striaté, fulvo-grisescente ;
costis rotundis, striatis, alteris distantibus exstantibus, alteris inter-
mediis numerosis depressiusculis; intis alba; margine duplicatim
denticulato, prope apicem calloso; callo postice truncato ; foramine
anticé declivi. Ods. ‘he ribs are peculiarly festooned with striz
arching upwards; about every fourth rib is more prominent than
the intermediate.
61. Mercauret (f. 140, 141, 142), Rve-—Quam FP. neglecta
angustiore, costellis magis equalibus. O%s, Although narrower and
more finely sculptured, this species, which includes F. viminea of
the same anthor, exhibits the same festooned striation over the
ribs, and otherwise resembles 7’. neglecta.
62. suBrosrrava (f. 215), Guild., Sowb.—Irregulariter ovali,
posticé attenuata, depress4, marginibus ad terminos elevatis, fusca,
scabrosa, costis acuté imbricatis subangulatis radiata ; ints alba ;
FISSURELLIDA. 193
margine laqeuato; foramine parvo, rotundo, supra medium posito.
Obs. This rough shell was distinctly figured in ‘Conchological Illus-
trations,’ f. 75, under the above name, which has the priority over
FL. salebrosa.
63. punta (f. 208), Ave.—lrregulariter oblong, depressi, ter-
minis elevatis, fusca, griseo obscuré radiatim fasciata, irregu-
lariter costis rotundis scabris imbricatis radiata; foramine oblongo,
infra medium posito. Ods. I have some difficulty in placing this
and the preceding species. It has been suggested to place them
with /. pustula and fascicularis under the genus Clypidella, but,
although they resemble those shells slightly in form, perhaps acci-
dentally so, the other characters do not correspond.
64. JuKest (f. 147, 148, 149), Rve.—Ovali, subelevata, albida,
striis elevatis concentricis et costis angulatis acuté imbricatis
radiantibus cancellata ; costis nonnullis exstantibus ; intts alba ;
margine duplicatim dentato; callo griseo posticé subtruncato ;
foramine quadrato; margine griseo, anticé declinato, supra medium
posito. Ods. This species is subject to considerable variations
in elevation, sculpture, etc. ; but the characters pass from one va-
riety to another interchangeably. The foramen is square, edged
with black, and placed considerably above the middle. F. 147 is
F, Jukesii of Reeve; f. 148 is F. fimbriata of the same author ;
f. 149 is named in the same work as /. australis of Krauss,
but it is quite distinct from that species.
65. Stusotpir (f. 138), Rve.—F. Jukesit simili, sed costis
quinque posticis, distantibus, validé exstantibus. Ods. A variety of
F. Jukesix oceurs, which has some of the front ribs very prominent,
and that variety presents an approach to this species, in which the
five principal ones are very prominent indeed and strongly imbri-
cated. This being a Chinese shell, is an additional reason for dis-
tinguishing it from its Australian analogue.
66. catycuLata (f. 126, 127), Sows.—Oblonga, posticé ex-
pansa, anticé lateribus compressis, apice elevato, costellis tribus mag-
nis imbricatis posticis alteris minoribus et interstitialibus minimis
radiata, liris concentricis cancellata ; intts albi; foramine subro-
tundo, multo ante medium posito, inttis callo septum formante
marginato. Ods. Remarkable for the internal callus near the
apex, which forms a kind of septum with a pit behind it, and the
three prominent notched ribs.
67. varicosa (f. 52, 53), Sows. G. B. 2.—Oblonga, conica,
194 FISSURELLID.®
apice elevato, costis tribus maximis validé nodulosis posticis, sex
anticis magnis, cum minoribus interstitialibus radiata, lineis ele-
vatis distantibus concentricis cancellaté ; intis callo vix septiformi ;
foramine parvo, rotundo, anticé posito et declinato, Obs. It is
not internally chambered as in 7. calyeulata. The three poste-
rior prominent ribs are very coarsely knobbed.
68. uxcetsa (f. 154, 155, 156), Rve.—Ovali, elevata, liris
concentricis et costis elevatis ineequalibus acuté imbricatis cancel-
lata; apice elevato; foramine parvo, subrotundo, antice posito.
Obs. F. alta, of C. B. Adams, has the cancellation a little coarser ;
but there are scarcely two specimens alike.
69. nrcRo-oceLiata (f. 160, 161), Rve—F. excelse simil,
sed maculis nigris, inter costis prope marginem positis. Ods. In
form scarcely differing from 7. excedsa, but with a minute black
spot between each of the principal ribs near the margin.
70. ocracona (f. 159). Rve. L. excelse simili, sed costis tribus
magnis posticis validé nodosis. Os. The specimens so named in
Mr. Cuming’s coliection, which most nearly resemble the figure of
this species, do not appear much more “ octagonal” than LZ. ex-
celsa; but the three prominent ribs in front are singularly
knobbed.
71. cyatnutum (f. 152, 153), Rve.—Ovali, elevata, liris dis-
tantibus concentricis et costis distantibus acutis angulatim nodu-
losis radiantibus cancellatd, fusco variegaté ; foramine parvo, ro-
tundo ; apice elevato. Oss. This species, by the coarseness and
sharpness of its cancellations, holds a middle position between the
F, excelsa group and the next species.
72. mmpricata (f. 162), Sow. G. B. 2.—Ovali, depressa,
sordide alba, fusco radiatim fasciatd, liris concentricis et costis
alternatim ineequalibus acute imbricatis cancellaté ; foramine parvo,
subcentrali. Ods. An ordinary patelleform species, but cancel-
lated by concentric ridges and imbricated ribs.
73. Lisvert (f. 130,131), D’Ord.—Ovali, depress, liris con-
centricis et costis 20 principalibus cum alteris interstitialibus ro-
tundis obtusé noduliferis cancellatd, fusea, alba, vel viridi radiatim
fasciata; intus albi; callo prope apicem subtruncato ; foramine
ceruleo marginato, supra medium posito, antice declinato, angus-
tato. Ods. This is the most coarsely cancellated among those
shells which have been included in the designation /. Greca. It is
West Indian.
74. stutmts (f. 148), Sows. G. B. 2.—F. Insteri simili, sed
FISSURELLID®. 195
multo magis elevaté; costis tenuioribus. Oés. The ribs are thinner
and the shell more elevated and conical than /. Listeri ; these
with the Australian habitat may justify the distinction.
75. revicutata (f. 112), Donov.—Oblonga, anticé attenuata,
depressi, costis parvis moniliferis ineequalibus et liris concentricis
ceancellata, pallidé fulva, viridi vel fusco radiat&; intus albi; mar-
gine denticulato; lateribus arcuatis; foramine parvo, multo supra
medium posito, declinato. O4s. This cancellated species has some
of the front ribs more prominent than the others. The basal
margin is arched at the sides.
76. cosraria (f. 117), Desh.—F. reticulate simili, sed costis
et liris minoribus, magis eequalibus ; margine basali ad latera recto.
Obs. The sculpture is finer than in F. reticulata, the ribs more
regular, and the basal margin not arched.
77. Stvcavorensis (f. 118, 119).—Oblongo-ovali, depressa,
albA vel pallidé fulva, interruptim fusco seu griseo radiatim fas-
ciaté, subarcuata, regulariter cancellata; foramine ovali, multo
supra medium posito, anticé declinato. Ods. Like F. reticulata,
but of a more oval form and more regular cancellation.
78. Latiora (f. — omitted), Sows. G. B. 2.—Quam F. Sin-
gaporensis multo latiore. Oss. I omitted a figure of this, not
intending to distinguish it from the preceding, than which, how-
ever, it is much broader.
79. ausrrauis (f. 158), Avavss.—Oblongo-ovali, depressi, pos-
tice convexd, costellis eequalibus moniliferis cum alteris mino-
ribus intermediis et liris minutis concentricis cancellaté. Ods.
The cancellation is much more close and regular than in /. Singa-
porensis, and besides the long radiate ribs, there are others inter-
mediate which, beginning later, are shorter.
80. trvgata (f. 134, 135), Sows.—Ovali, anticé subattenuata,
declivi posticé convexa, regulariter cancellaté ; costellis nonnullis,
moniliferis, rubris; intus albA; margine duplicatim denticulato ;
foramine ovali, anticé posito declivi. Ods. Although first figured
from a smaller specimen, there can be no doubt of the identity of
this shell, to which the name subsequently given by Mr. Reeve
was therefore unnecessary. A few of the beaded ribs are a little
prominent and coloured red, and although this is not the case with
the larger variety which is obscurely rayed with clouded green,
yet the more prominent ribs are present undistinguished by the
red line.
81. penstctaTHRata (f. 157), Rve.—Ovali, subdepressi, co-
196 FISSURELLID &.
nici, omnino equaliter cancellatd, sordidé alba viridi-grisescente

A patelleeform species, evenly cancellated, with the foramen near
the centre, painted by obscure greenish or greyish bands,
82. venusta (f. 109), Ave.—Ovali, depressi, alba, costellis
levibus cum alteris intermediis radiantibus et liris concentricis
regulariter cancellata ; foramine paulo supra medium posito. Ods.
A beautifully cancellated, white, patellaform species.
83. Bompayana (f. 166), Sowd. G. B. 2.—Ovali, depressi,
liris concentricis et costis acutis scabris equaliter cancellata,
fulva, fusco radiatim fasciata ; intts alba; marginé crenulato ; fora-
mine rotundo, supra medium posito. Oés. A pretty species, re-
sembling /, venusta, but delicately ranged with brown bands and
with the costell scabrous.
84. runicuLata (f. 100, 129), Rve.—Ovali, posticé vix atte-
nuata, subconica, concentricé tenuiter striata, costis rotundis scabris
numerosis quarum nonnullis majoribus exstantibus imbricatis ra-
diata, albi, fulvo-radiatim fasciaté, nonnunquam costis majoribus
fusco-lineatis; foramine ovali, declinato, multo ante medium posito.
Obs. The original variety, f. 129, has its delicate radiate bands
bordered by rather prominent brown ribs, forming beaded lines
in pairs; and although the var. subsequently named /. dacty-
dosa has not these ribs coloured, it presents the same sculpture and
is no doubt identical.
85. niariraprata (f. 167), Rve.—Parva, oval, conica, alba,
liris concentricis et costis moniliferis validis radiantibus quarum
9 interruptim nigris cancellaté; foramine subrotundo, simplice.
Obs. A small, coarsely cancellated species, 9 of whose beaded ribs
are interruptedly black.
86. Panamensts (f. 128). Sowd.—Parva, elevata, alba, conica,
fusco prope marginem fasciatim variegata, lineis fuscis angulatis
ornata, omnino minute cancellati, costellis albis paulo exstantibus
radiata ; apice elevato; foramine circulari, simplice, longé ante
medium posito. Ods. In the ‘Conchological Illustrations,’ this
very distinct shell is united with the one which Mr. Reeve has
since named F, excelsa: see f. 154, 155, 156.
87. tarva (f. 102, 103, 104), Rve.—Oblonga, depressa, fusco-
subviridi, albo radiata yel alba, nigro vel griseo radiatim fasciata,
concentricé liraté, costis 18 exstantibus rotundis valde imbricatis
et interstitiis tricostatis radiata, intis albA; margine duplicatim
denticulato ; callo prope apicem posticé truncato; foramine decli-
PISSURELLID. 197
nato, anticé angustato, supra medium posito. Oés. Of an oblong
depressed form, with eighteen imbricated rounded ribs, and three
smaller ones in the interstices. he fissure is singularly nar-
rowed anteriorly.
88. Dysonr (f. 105, 106), Rve.—F. darve simili, sed magis
conica ; costis magis angulatis, acuté imbricatis. Ods. More coni-
cal than /. darva, with the ribs and imbrications more angular.
89. rumata (f. 95, 96, 97), Rve—Ovali, conicd, anticé an-
gustatd, alba vel griseo-nebulosa, post foramen angulatim elevata,
concentricé lirati; costellis rotundis crebris, quarum 18 majori-
bus radiatis ; foramine declinato, anticé angustato, ceruleo mar-
ginato, ante medium posito. Oés. The variety figured in Reeve’s
work appears to be an unusual one ; the smoky tints of our figures
are more natural to it. The apex is elevated into a point behind
the anteriorly-narrowed fissure.
90. atrernata (f. 98, 99), Say.—Oblonga, quam 7. fumata
magis angusta, fusco-subviridi fasciatim variegata; costis majoribus
acuté imbricatis. Oés. Narrower than £. /umata, with the more
prominent ribs sharply imbricated, and the colouring variegated.
91. Rupwxutt (f. 107, 108), Sows.—Ovali, anticé subincurva,
posticé convexd, alba, fasctis quatuor vel octo nigrescentibus, vel
fulva vel prope marginem rufescente-nigro radiata, costis validis
rotundis moniliferis et liris concentricis parvis cancellata ; intis
albo, margine minute denticulato; foramine declivi, ovali, sim-
plice, supra medium posito. Ods. The rounded and beaded large
ribs distinguish this species from others.
92. Ticaonica (f. 110), Ave.—Oblonga, posticé gibbosa, an-
ticé valde declinata, concentricé leviter lrata, costis scabris radiata,
alb& viridi tincté, nonnunquam viridi interruptim radiata ; fora-
mine angustato, tripartito, prope marginem anticum posito. Ods.
The tripartite fissure, the fine and rather sharp cancellation, and
the nearness of the apex to the ventral margin, serve to distinguish
this species.
93. proxima (f. 115), Sows. G. B. 2.—F. Ticaonice simili,
sed posticé haud tantum gibbosa, anticé haud tantum declinata.
Obs. Less gibbous posteriorly and less suddenly inclined than
F’. Ticaoniea, which it nearly resembles. The variety figured is

lato ; foramine rotundo, antico profundo, margine postico elevato.
Obs. A whitish shell with purple rays, rendered scabrous by the
fluted edges of former stages of growth, and radiating ribs rough-
ened by the crossing of these lines.
98. aspera (f. 125), Sow.— Ovali-subrotunda, conica, ele-
vata, fusco-nigricante, vel obscuré fasciata ; liris elevatis, fimbriatis ;

99. ura (f. 124), Sows. G. B. 2.—F. aspere simili, sed liris
concentricis et costis radiantibus wulto minoribus; foramine
parvo, oblongo. Ods. The sculpture is so much finer than F.
aspera as to compel the separation; the foramen is also small and
narrow.

vata, striis minutis scabris radiata; apice validé versus marginem
anticum inclinato; olivaced, prope apicem subceerulea, intus alba,

101. renursrriata (f. 111), Rve.—Oblonga, gibba, alba,
apice versus marginem anticum inclinat&, prope apicem minuté
cancellata, versus marginem minuté radiatim scabroso-striata ;
foramine magno, rotundo. Oés. An oblong gibbous white shell,
very short, anteriorly cancellated near the apex, the radiate ribs
thinning out into even striz near the basal margin. The foramen
is very large and round.
102. pinzopsipgs (f. 120, 121), Rve.—Obliqué gibbosa ; apice
ultra marginem basalem incurvato; pallidé fulva, prope apicem
rubro tincta; costis crenulatis, rotundis, quarum alternis depressis
radiata; foramine elongato, declinato. Ods. The name is happily
chosen to express the curving of the apex and its leaning beyond
the front basal margin.
103. crppa (f. 114, 168), Phzdippi.—Oblonga, alba, convex,
liris concentricis et costis noduliferis radiantibus cancellata ; fora-
mine oblongo; variat subolivaced, fasciis viridis radiata. Obs.
Distinguished by Philippi from the following by the greater con-
vexity of its back and sides. F. candida, of the ‘Con. Ill” pro-
bably belongs to this.

tenuati, alba vel variegata, cancellata ; lateribus depressis; margine
basali arcuato; foramine oblongo. Oés. This species has the
sides and back more depressed, the basal margin more arched, and
the anterior more narrowed than the preceding.
105. Grantrera (f. 165), Pease—F. gitbe simili, sed multo
breviore. Ods. Much shorter than 7. gisda.
106. arcuata (f. 168, 164), Sows. G. B. 2.—Parva, alba,

arcuata, fulvo-virescente, radiatim lmearum fasciculis fasciata, con-
centricé lirata, costellis crebris minuté noduliferis radiata; intus
griseo; margine crenulato; foramine parvo, uigro-marginato, prope
marginem anticum posito. Oés. This little shell was figured in
the ‘ Conchological Illustrations,’ and agrees well with Lamarck’s
description of the species. Mr. Reeve’s subsequently-imposed
name, /. gemmulata, must therefore be dropped.
200 FISSURELLID.
108. vartreatTa (f. 172, 173), Sows. G. B. 2.—Quam F.
minuta magis depressa, cancellata, alba, fasciis interruptis radianti-
bus variegata; foramine oblongo, margine albo. Ods. This species
is variegated with interrupted radiating bands; it is flatter than

elongated arched species, variegated by angular broad patches of
olive-green. The foramen is round.
111. imevatis (f. 183, 184), Sows—F. pice simili, sed
coloribus suffusis ; foramine elongato, tripartito. O4s. The colours
in this species are radiated and suffused, the back is less arched
than in the preceding, and above all, the fissure, instead of being
rounded, is long, narrow and lobed.
112. corsicuta (f. 180), Sows. G. B. 2—Quam F. pica et
F. inequalis magis depressa, patelleformi, valide cancellata. Ods.
Less arched than the preceding, with coarser cancellation.
113. tancrorata (f. 182), Sowd., G. B., 2—Quam F. pica
et F. inequalis anticé multo magis angustata. Oss. The sud-
den narrowing of the front part distinguishes this from the two
preceding species, besides the cancellation being a little more
depressed.
114. arricunata (f. 176), Sows. G. B. 2.—Hlongata, com-
pressa, fulva, fusco fasciatim variegata, liris concentricis et costis

FISSURELLID&. 201
distincto; margine aperture minuté denticulato ; foramine magno,
circulari, longé ante medium posito. Ods. Lf. suffusa, Rve., is
only a variety of this without the variegated bands.
116. mets (f. 188), Rve-—F. cancellate simili, sed magis de-
pressd; fasciis distantibus; costis magis distantibus et acute angus-
tatis ; foramine oblongo. Ods. Flatter than F. cancellata, with
narrower, more distant, and sharper ribs.
117. enoneata (f. 185), Philippi Quam F. egis multo an-
gustiore. Ods. Although much narrower than F. e@gis, this
shell is not very distinct from that species.
118. cructata (f. 191), Avawss—Quam F. @gis ad apicem
magis elevata, costis radiantibus haud tantum extantibus, alba,
fasciis fuscis quatuor cruciatim radiata. Os. The apex is more

ceding species, with the ribs sharp and close as in F. erwciata.
Oés. It is white, speckled with grey in radiating bands.
120. crentrera (fig. omitted)—Oblongd, validé depressa,
alba, fasciis rubris sex latis picta, costis distantibus nodosis ra-
diaté; intis albo margine crasso, crenulato; foramine oblongo,
prope medium posito. Ods. A figure of this has been inadver-
tently omitted; it is flat and oblong with nodulous ribs, and a
nearly central oblong foramen.
121. acurmara (f. 186), Rve-—F. crenifere simili, sed alba,
costis alternis acuté imbricatis. Ods. Differmg from F. erenifera
in the sharp imbrications of the more prominent ribs.
122. sacrrrata (f. 83).—Oblongé, depressa, radiatim stri-
at, alba, fasciis roseis 11 et maculis angulatis fasciata, intis alba ;
marginibus terminalibus paulo elevatis; foramine oblongo, paulo
supra medium posito. Ods. Prettily radiated with pink bands,
between which are angular brown spots.
123. crenutava (f. 18), Sows.—Magni, expansi, ovali-ob-

A large shield-like species.
124. Hantnyana (f. 174), Sowb. G. B. 2.—Parva, alba, sub-
depress, anticé angustaté, minuté cancellata, intis alba, mar-
gine leviter crenulaté; foramine subtrigono, lateribus aculeatis,
prope medium posito. Ods. The triangular fissure in this species
has a little elevated point at each side.
Genus FISSURELLIDEA.
Char. Gen. Molluscum gasteropodum, testa patellaeformi, dorsali
pallio tecta ad apicem, fissuraé magna perforata, margine aperture
ad extremitates elevato.
The characters of the shells alone are not sufficient to distin-
guish this genus from the preceding, although the fissure is larger
than in Fisswred/a,and the basal margin is elevated at both ends ;
but in F. Aiantula the shell is covered almost entirely by a lobe
of the mantle, and although the animals of the other species are
not all known, I have placed together those whose shell would ap-
pear probably to belong to the same type.
Species of Fissurellidea.
1. utantuxa (f. 193, 194, 195), Zamk.—Testa oblonga, antice
subangustata ; lateribus compressis, terminis elevatis; i1mpresso-
striaté griseo, olivaceo vel rubro varié radiata et picta, intts alba ;
callo valido, margine leviter crenulato ; foramine magno, ovali,
paululum infra’ medium posito. Oés. Rather narrower anteriorly,
and, by being as it were pinched in at the sides, the basal margin
is open at both ends.
2. Cuemnirzi (f. 29, 192), Sowb.—Ovali, crassi, anticé an-
gustata, lateribus compressis, roseo radiata, concentricé undulatim

not so much pinched at the sides or elevated at the ends.
4. incarnata (f. 199), Krawss.—Oblonga, rosea, albo radiata,
tenuissimé radiatim striata, anticé angustaté; terminis paululum
elevatis; foramine centrali, magno. Ods. Rose-coloured with
whitish rays very finely striated, the ends a little turned up, but
not so much so as F. hiantula:
5. sEtta (f. 197), Sows. G. B. 2.—Brevi, anticé angustata ;
lateribus paulo compressis, terminis validé elevatis ; fulva-rubes-
cente, minuté striata, intis grised; margine levi, callo purpureo
circumscripto. O%s. An interesting saddle-shaped shell, which
has the peculiar pinched-up character of /. hiantula, etc., but
is much shorter. It has the ends raised more than any other
species.
6. scuTELLA (f. 207), Sowd. G. B. 2.—Subquadrata, depressa,
levi, concentricé minutissimé striaté; terminis elevatis ; fulva,
fuscis fasciis inequalibus radiata; foramine magno, medio sub-

pressis, terminis elevatis; radiatim striata, migrA; foramine
maximo, ovali, centrali. Ods. Black, finely striated, with the ends
raised, and very large central fissure.
8. compranata (f. 201), Sowd. G. B. 2.—Oblonga, depressa,

radiata, lineis concentricis crenulatis cincta, pallidé fulva, fasciis
griseis 6 ineequalibus radiaté, intts alba; callo apicali cireum-
scripto; margine incrassato, minuté crenulato ; foramine magno,
ovali. Radiated with impressed lines, which are striated by fes-
tooned or crenulated lines of growth.

Although the ends are scarcely raised, the general form of this
shell seems to place it near /. nigrita, ete.
204 FISSURELLIDA.
Genus PUPILLAVA.
Char. Gen. Molluscum gasteropodum, testa patelleeformi, dorsali
interna; testee foramine maximo, ovali; margine basal, ared de-
pressi. cincto. Obs. The species upon which this genus is
founded, has the peculiarity of a depressed insertional rim, re-
sembling that by which the valves of a Ciiton are inserted into
the surrounding integument. ‘The shell is covered by the mantle.
PurinnHa aperra (f. 228, 229), Sows.—Oblonga, s subconica,
crassi, anticé magis gibbi, posticé magis depressi, grisea, ina-
qualiter nigro fasciata et punctatéi ; margine impresso, albo, tenui ;
foramine maximo, ovali. Oés. The nearest shell to this in fend
is Fissurellidea migrata, but neither that nor any other has a
similar insertional rim at the base.
Genus CLYPIDELLA.
Char. Gen. Molluscum gasteropodum, testé patelleeformi, dorsi
partem tegente ; teste foramine parvo, subcruciformi; margine
antico elevato. Obs. The flat saddle-shaped character of the shell,
and its small size compared with the animal, and the different
appearance of the animal itself, are perhaps sufficient to justify
the separation of the two known species composing this genus
from the other Fissureliida.
Species of Clypidella.
1. pustuta (f. 209, 210, 211), Lamk.—Testa subcireulari, de-
pressi, antice paululum angustata, margine elevato; emarginate
alba seu rosed, seu roseo radiatim fasciati, costis depressis, crebris,
concentricé striatis et interstitiis lmearibus radiata ; intts alba,
margine crenulato ; foramme subcruciformi roseo marginato
prope marginem anticum posito. Ods. The ribs are depressed
and close together, and the anterior margin is a little sinuous and
elevated.

front, not emarginated, with the ribs more rugose and rounded
than in C. pustuda, and the fissure placed nearer to the centre.
FISSURELLIDE. 205
Genus MACROCHISMA.
Char. Gen. Molluscum gasteropodum; testa patelleeformi, oblonga,
dorsali, versus extremitatem posita; teste foramine maximo, elon-
gato, prope marginem anticum posito, terminis elevatis. Ods. Mr.
Cuming remarks that the animal of this genus is very large and
elongated, with the shell placed near the hinder extremity. The
shell has the compressed sides and elevated extremities of the
genus /sswrellidea, but it is much prolonged backwards; and the
foramen is very long, narrowed behind, widened in front, where it
is placed close to the anterior margin of the siiell, which is de-
pressed immediately in front of it.
Species of Macrochisma.
1. maxima (f. 216, 217), 4. Adams.—Testa oblonga, radiatim
striata, fusco et rubro radiatim fasciataé, posticé subdepressa,

variegati, tenui, posticé attenuata, subacuminata; foramine maximo,
posticé acuminato. Oés. Differing from the last in its greyish
colour, in the narrowness and pointedness of the foramen and pos-
terior margin. ‘These last two species may prove to be the young
of some other species.

striata, fuscé; anticé margine validé slernia, posticé margine pau-
lulum elevato; foramine oblongo, magno, prope medium posito.
Ovs. A wide species, in which the fissure is not placed so near
the front edge, and in which the space between the fissure and
margin Js scarcely depressed. It forms almost a link between
this genus and Misswredlidea.
9. pinatata (f. 220), 4. dd.—Oblonga, striata, subquadrata,
depressa, rubra ; anticé margine elevato vix sinuato, posticé paulu-

208 FISSURELLIDE.
This species, figured from a specimen in Mr. Cuming’s collection,
is of quite a different form to C./astigiata, and seems to approach
more nearly to C. xoachina in specific characters.
4. cucuttata (f. 3, 4, 5), Gould.—Solida, cinerea, perin-
equilateralis, costis ad 40 acutis compressis majoribus et mino-

vato, radiatiin costata; costis longitudinalibus, validis, subdistan-
tibus, equalibus, striis concentricis confertis corrugatis; fissura
angusta, lanceolata ; apertura ovata, margine crenato, fornice costa
transversali. Ods. In this species the ribs are very distinct, and
the concentric raised lines are acuminate where they cross the

young individuals, however, the foramen is entire. 4. Adams.
(I do not find it possible to distinguish satisfactorily the sub-
genera “ Subemarginula”’ and “ Clypidina’’ The notch, upon
which the division principally depends, graduates from a great
depth in some species to being scarcely perceptible in others, but
no line of demarkation can be drawn. In most species the depth
of notch depends on the age of the specimen, being deeper in the
young. G. B. 8.)

tween each of the larger ribs.
53, atveorata (f. 82, 83), 4. Adams.—Tenuis, alba, subpel-
lucida, depresso-conica, vertice subcentrali, posticé inclinato,
costis radiantibus lirisque transversis irregulariter alveolata ; costis
ad liras nodulosis ; alveolis pellucidis ; aperture margine dentato,
antice sinuato, sinu intts in canalem producto.
54. cravitra (f. 91), 4. Adams.—Ovata, conica, albida, vertice
obtuso, central, posticé haud inchnato, costis radiantibus distanti-
bus, nodulosis; interstitiis costellis duabus longitudinalibus, et
lineis elevatis, transversis eleganter cancellatis ; aperture margine
crenulato antice simuato, sinu quadrato, itis in canalem producto.
Obs. Only the formation of the fissure and cicatrix distinguish
this from F. viminea.
FISSURELLID. 219
55. Guapatoupensis (f. 69), Sows.—Ovata, depressa, irregu-
laris, rugosa, apice subcentrali, costis radiantibus magmis quarum
tribus posticis majoribus, duabus anticis maximis, cum alteris in-
termediis et parvis; costis concentricis irregularibus ; interstitis
foveolatis ; fissura parva, cicatrice in costam elevatam producta.
Obs. Tf such a shell as #. Panhiensis were flattened, it would
present an appearance resembling this species.
56. ocronaptata (f. 66), Gme/.—Ovata, conica, patelliformis,
costata, alba vel albo-virescente, anticé intis canaliculata, margine
subemarginato, costis octo eminentioribus. Ods. The eighth ray
is formed by the cicatrix- of the fissure, which ends in a shght
notch at the margin.
57. peprussa (f. 64, 65, 68), B/aznv.—Patelliformis, alba,
ovato-oblonga, lateraliter depressa, costata, costis novem eminen-
tioribus; striis transversis clathratis.
58. RuGosa (f. 92, 93, 95, 96, 97, 98, 99, 100, 101, 102),
Quoy.—Hlongato-ovalis, oblique conica, costis radiantibus, ele-
yatis, distantibus, asperulatis, interstitiis costellis longitudinalibus
et lineis scabriusculis valde cancellata; vertice subcentrali, posticé
inclinato ; aperturee margine dentato-crenulato, incisurd profunda,
ints in canalem producté. Ods. In the whole of the varieties
figured, which have received so many names, we see only the
same general characters with different degrees in the asperity of
the ribs, resulting from the age of individuals saa other modifying
circumstances.
59. putcura (f. 50, 51), 4. ddams.—Depresso-conica, viridis,
albo pulcherrimé radiatim picta, vertice subcentrali, postice in-
clinato, costis radiantibus, ineequalibus aculeato-asperis, intersti-
tis lineis elevatis transversis clathratis; apertures margine denti-
DEAS Ce 3G A : A Mh
culato, anticé inciso, fissuri brevi subquadrata. Ods. This re-
sembles the sharper aud younger specimens of /. rugosa, but all
the radiating ribs in the anterior half of the shell are equal.
60. sretuata (f. 103), 4. ddams.—Solidula, albida, elliptica,
depresso-conica, apice subcentrali ; costis elevatis, subspinulosis,
radiantibus ; interstitiis costellis et striis crebris decussantibus,
exasperatis ; aperturee margine dentato, sinu sublaterali, intts in
canalem apicem versus producto. Oés. This differs from any
of the varieties of #. rugosa in the production of the ribs at their
marginal termination, and the greater coarseness of the sculpture
generally.
61. suncrrpra (f. 84, $5), 4. ddams.—Ovalis, depresso-conica,
220 FISSURELLID&.
viridescens, vertice obtuso, ad partem posteriorem posito ; costellis
radiantibus, interstitiis haud eequantibus, et striis incrementi or-
natis, basi arcuati; aperture margine crenulato, incisura haud
profunda sublaterali, intis in canalem producti. Ods. In the
one-sided position of the notch in this ove species G. B. 8. does
not see a sufficient reason for the erection of a separate genus.
62. norata (f. 86, 87, 88), Zinz.—Ovalis, depressa, cinerea,
nigro lineata et maculata; apice postico, obtuso; costis radianti-
bus nigris, rugosis, inequalibus ; margine antico vix emarginato,
intis cicatrice inconspicud. Ods. In this species the fissure has
been filled up almost or quite to the margin, and is only percep-
tible by a shght notch and an inconspicuous cicatrix.
Genus SCUTUS, Montfort.
Parmophorus, Scutellites, Dascinum, etc.
Puates XIII, XIV.
Char. Gen. Molluscum gasteropodum ; capite proboscidiformi ;
tentaculis crassis et subulatis; oculis in tuberculis ad bases ex-
ternas positis; pallio super testam reflexo; pedum latera cirro-
rum serie instructis ; testa oblonga, suleiformi, depress 4, apice
dorsali oblique posticé inclinato ; aperture margine anticé sinuato ;
impressione musculari oblonga, posticé semicirculari.
1. nLroneatus (f. 1, 2, 10, 21), Lamk.—Tenuis, elongata, an-
terlus integra, striis exiguis radiata; marginibus acutis. Obs.
The concentric lines are scarcely waved. The surface is slightly
striated.
2. uneuis (f. 19), Zimz.—Solida, glabra, utrinque subtrun-
cata, striis concentricis ineequalibus impressa, dorsi animalis lon-
gitudinem equante, marginibus incrassatis. Ods. Very straight,
oblong, square at the anterior end, with straight lines of growth.
3. BREvICULUS (f. 6), Blaine.—Solida, glabra, dorso convexo
animalis longitudinem non eequante. Ods, This shell is very
much shorter in front than the other species.
4. corrueatus (f. 4, 7), Reeve.—Hlongata, utrinque subro-
tundata, dorso plano, striis concentricis validis corrugatis instructo.
Obs. Shaped like S. edongatus, but with the concentric lines waved
strongly so as to form a corrugated surface.
FISSURELLID&. 221
5. eranutatus (f. 3, 20).— Testa superne tuberculis parvis
granulata.” Ods. The concentric lines are waved and thickened
into little knots or tubercles. These are not so conspicuous in
the variety termed S. imbricatus, Quoy et Gaim. The shell is
narrowed in front, with an arched back.
Subgenus Tueatia, Gray.
Prats XIV.
Char. Gen. Testa patelliformis, oblonga, anticé angustata,
dorso elevato, arcuato; apice postico et recurvo ; aperture mar-
gine crenulato et anticé profunde sinuato.
The narrowness of the shell in front, the arched character of
the back, the decussated structure of the outer surface, and the
crenulated margin of the aperture, will be thought to distinguish
this sufficiently from Parmophorus.
1. parmMopHoripEa (f. 5, 11, 16), Quoy.— Ovato-oblonga,
convexa et arcuata, margine denticulato, luteo-virescente, striis
tenuissimis asperis atque confertis cancellata; vertice obtuso,
rimd fere nullA. Ods. This is convex and rather narrow at the
anterior end, the radiating ribs strongest.
2. ossga (f. 18), Gou/d.—Crassa, rudis, albida, quadrangu-
lari-elliptica, costis radiantibus numerosis inequalibus acutis et
strils incrementi decussata, basi arcuaté; margine crenulato, cica-
trice musculari bene impressd, incisurd haud profunda, intis vix
in canalem producté. Os. Much like 7. cinerea, but not so
long nor so tapering in front.
3. crneREA (f. 15, 17), Gow/d.—Cinerea, F. osseo similis sed
tenuior, altior, magis disposité et delicaté clathrata, cicatrice muscu-
lari inconspicua ; incisurad minimé profunda, in canalem interiorem
valde insignem producté. Ods. The rays are imbricated, and the
form is more elongated and depressed than in 2. parmophoridea.
7’. ossea 1s a shorter and thicker shell.
4, carinata (f. 13), 4. ddams.—Hlongato-ovalis, dorso cari-
nata, costis longitudinalibus, radiantibus, confertis et striis trans-
versis, concentricis, decussata ; apice posticé declinato, basi ar-
cuata ; aperture: margine crenulato, extremitate anteriore sinuata,
sinu intts in canalem producto. Os. The anterior sinus is conti-
nued to the apex as a keel without and a groove within the shell.
222 FISSURELLID®.
5. pecussata (f. 12), A. Adams.—Elongato-ovalis, albida,
planulata, dorso carinata, costellis longitudinalibus, radiantibus,
et lineis elevatis concentricis eleganter clathrata, vertice acuto,
postico; aperture margine crenulato, anticé sinuato, sinu intus
in canalem producto. Ods. With a regularly cancellated sculp-
ture and a keel from the anterior margin to the apex.
6. crcatrosa (f. 14), 4. Adams.— Elongato-ovalis, alba, dorso
valde depressa, costellis radiantibus et lineis concentricis elevatis
decussata, vertice subpostico depresso excavato quasi cicatricoso,
subpellucido, basi arcuat&é; apertures margine crenulato, extre-
mitate anteriore sinuatd, simu intus in canalem producto. Obs.
The sinus and cicatrix as in Z. carinata, but the shell flat and
strongly cancellated.
7. scuretiaris (f. 8, 9), 4. Adams.—Elongato-ovalis, virido-
fusca, tenuis, dorso planulata, vertice postico, acuto, vix elevato,
costellis radiantibus subdistantibus, et striis concentricis incre-
menti decussata ; extremitate anteriore vix sinuato ; aperturd intus
fuscd, margine crenulato.

MONOGRAPH
OF THE RECENT SPECIES OF THE GENUS
SOLARIUM of Lamarck.
By SYLVANUS HANLEY, B.A., F.L.S., etc.
Char. Gen. More or less conoidal or disciform, with a large
umbilical cavity, which, for the most part, is denticulately crenated
within ; periphery more or less angular in general; mouth never
pearly ; operculum horny ; spiral, oval, or circular.
Section A. (Architectoniea, Bolten.) —Periphery angular;
mouth rhombic; whorls belted above, usually with radiating
sculpture ; inner lip straight, or nearly so, with a single canalicu-
lated notch at the termination of the umbilical cord, which latter
is always creno-dentated ; umbilicus never ribbed spirally ; oper-
culum suboval, flattened, quickly spiral at one end; internal
nucleus circular-based, composed of very numerous erect scales.
Section B. (Philippia, Gray.)—Shell as in the last, but the
whorls not belted posteriorly, and devoid of radiating sculpture ;
operculum circular-based, multispiral, concave externally, inter-
nally with a small abrupt central mammillary apex.
Suction ©. (Zorinia, Gray.) —Surface corded throughout ; peri-
phery bluntly biangulated or even rounded, more rarely angular ;
mouth more frequently suborbicular; umbilicus in the typical
species relatively narrow, and encircled by one or more spiral
ridges; operculum circular-based, multispiral, composed of nu-
merous membranaceous layers, either forming a peak or truncated.
My aim in adopting these sections is to enable the conchologists
of both the Lamarckian, and the more modern English school, to
arrange their cabinets according to their several predilections.
228 SOLARIUM.
Otherwise I should have preferred for divisional purposes, the selec-
tion of characters wholly based upon the shell, and independent
of the rarely obtained opercula. 1 am inclined to think that such
species as S. infundibuliforme are quite as far removed from
Torinia as Philippia is from Architectonica, and that the loosely
coiled Bifrontia is scarcely within the limits of the genus.
* Sect. A. ARCHIVECTONICA.
1. persrectivum (f. 36, 37, 38), Linn.—T. depresso-conica,
sulcis remotis validis (corpore levi excepto) radiatim sculpta.
Anfractus spiraliter unisulcati, infra suturam angustam brunnei
et deinde candidi (varius subarticulati), infra sulcum spiralem
zona fusca ornati, deinde laté fulvi seu cinerei; cingulum supra-
suturale rufum seu fuscum, nonnunquam albo anguste articulatum.
Carina angusta, fulvo remote articulata. Sulcus peripherie superior
perangustus et seepius (etiamque inferior) unifilesus ; are basalis
medium sulcis radiatum, maculis lineisve interruptis intus margi-
natum. Crenz umbilici latioris brunnez, permulte.— Var. (incisa,
Phil.). T. pallida ; anfractuum zona superior, nisi in corpore, fere
albida ; zona infra suleum angusta, in corpore articulata; cingu-
lum suprasuturale brunneo et albo articulatum. Carina angusta,
acuta. Macule articulationesque basales seepius pauciores et. re-
motiores : cingulum album basale haud erasse crenatum.—Vanr.
(Australis, Plul.). T. pallidé cinerea; zona anfractuum superior
fere ut in var. precedente ; zona angusta, infra suleum spiralem
continua. Sulci radiantes crassi et valde remoti. Cimgulum su-
prasuturale brunneo-rufescente articulatum. Carina obtusa. Area
basalis media sulcis, plicisve, crassis radiata. Umbilici parvi
crene rufe, satisque magne. Ods. Not only the Linnean type
of Trochus perspectivus, but the great majority of the synonyms
in the tenth edition of the ‘Systema’ indicate this common species.
Var. S. incisa, Phil., is very pale in colour, with the crenated edge
of the umbilicus white with light brown spots: the peculiarities
of his Australe are most perceptible in young specimens.
2. TROCHLEARE (f. 19, 20), Hinds.—'T. S. perspectivo persimilis,
sed major, carneo-fulva; differt etiam apice nunquam cinereo-
nigrescente, sulcis radiantibus magis contiguis, vittd infra suleum
spiralem angustiore (quartam partem latitudinis illius areee tantum
implente), et semper in anfractu ultimo articulata, sulco spirali,
sulco peripheriz et sulco cingulum suprasuturale precedente latis ;
articulationibus carine acutissime brunneis, latisque; maculis in
media area disci inferioris magis irregularibus, flammasque simu-

lantibus. Ods. This common shell has been generally accepted as
the Zrochus perspectivus of Linneus. Of the many figures cited
by that author in the tenth or standard edition of his ‘Systema,’
not one represents it; and in the twelfth, or final edition only one
(Seba, ii. pl. 40, f. 1, 2). Hinds, whose ideal of the Linnzan
species was the S. maximum, described this species from a rather
elevated abnormal specimen.
3. Maximum, (f. 5, 6), PZ2/.—T. depresso-conica, sulcis confertis
obliquis (corpore levi excepto) radiata. Anfractus, infra suturam
latam, suleis profundis 2 (quorum superior est latior), et super
cingulum suprasuturale, quod (etiamque carina, basis cingula,
zonaque superior) fusco-rufescente et albido est articulatum, altis
tenuioribus obscuris instructi. Aree medi fulvee ; apicem versus
cinere, pallido violaceo tincte. Sulcus peripheria superior
latus, filis 1-2 divisus; inferior filosus, satisque latus. Basis
area media plerumque marginem exteriorem versus subretusa ;
interiorem versus maculis subremotis brunneis notatum subpla-
nulata, et seepius radiatim crassé suleo-plicata. Crenze umbilici
amplissimi permulte, vix pergrandes, albe seu pallida, aliquando
sparsim maculate. O4s. The deeper the spiral sulci, the more
elevated are the belts. The second zone is never articulated.
4. mopustum, (f. 11, 12, 27, 28), P&cd.—T. depresso-conica,
radiatim sulcata (corpore levi excepto). Anfractus superne bis
longitudinaliter sulcati; vitta superior angusta, alba, vel brunneo
remote maculata, vel brunneo pallidiore confertius nebulosa ; vitta
inferior brunnea, et aliquantulum latior. Area media lata, fulva ;
cingulum super suturam angustam vel brunneum (aliquando su-
perne tantum), vel brunneo pallidiore et saturatiore subarticu-
latum. Carina albida, vel strigis fulvis perangustis ornata, vel
brunneo remotissimé subarticulata. Sulcus peripheralis angustus
unifilosus. Basis vel tota immaculata, vel cingula ejus brunneo
remotissimé articulata, et margo interior areee medie levigatee
(aut sulcis obsoletis radiates) maculis linearibus brunneis pictus.
Sulcus inter carinam et cingulum proximum basale satis latus,
anifilosus. Umbilicus (et crene ejus albe satisque multee) hand
permagnus. Ods. Mr. Taylor possesses an example which is devoid
of the second spiral groove.
5. quapricups (f. 3, 4, 25, 26), Hinds.—T. depresso-conica ;
sutura conspicué canaliculata. Anfractus omnes sulcis 3 spiralibus
crassis (infimo presertim) divisi, et sulcis subcontiguis radiantibus
(nisi in anfractu ultimo) crassé decussati. Vitta prima et quarta
brunneo et albido (vel pallidé fulvo) subremote articulate ; vitta

secunda et tertia (omnium latissima) cmruleo-cinerex, livido-
carne, aut rubro-fulvee. Sulcus, inter cingula gemina peripherie
lata eequalia similiterque maculata, multo angustior quam cingula
ipsa et in adultis filosus. Basis area media sulcis rudibus ra-
diata, et umbilicum versus (tantum in senioribus amplum et
multidentatum) maculis remotis marginata. Crenee umbilici (in
junioribus ampli) rufee vel livido-fuscee. Ods. This species,
although named only a few years, was probably known to the
older conchologists. Both Gualtier (pl. 65, f. O, outer) and
Chemnitz (Conch. Cab. v. f. 1691-2, copied as 8. granulatum ? in
Kuster’s Chemnitz) have figured So/aria, which closely resemble
the more mature examples.
6. Taytort (f. 31, 32), Hanley.—T. depresso-conica, solida,
fulva; sutura laté canaliculata, Anfractus im cingula 4, fusco-
rufescente articulatim picta (tertio, quod duo preecedentia fere
eequat, excepto) et sulcis radiantibus (nisi in anfractu ultimo)
rudibus subremotis in rhombos latiores (¢. 3 excepto) quam altos
diffracta, sulcis latiusculis (tertio praesertim) eximie divisi. Sulcus
preecedens peripheriz cingula gemina, subzequalia, similiterque
picta, valde latus, profundus; intervallum in adultis filosum, aque
latum. Area basis media maculis brunneis perparvis tantum
juxta marginem interiorem ornata; alibi magis minusve levis.
Sulcus carine declivi proximus latiusculus, vix filosus. Cin-
gulum inter suleos latos umbilico vicinos, conspicué angustum.
Umbilici subangusti crene satis magne, carneo-rufescentes. Obs.
In the only examples known to me, the articulation is not deve-
loped upon the earlier turns; the first belt, however, is paler
than the rest. The coarser sculpture, and the articulation of the
second zone, alike distinguish it from maximum and quadriceps.
7. Nosite (f. 35), Bolten.—T. valida, depresso-conica, albo-
violascens ; sutura caniculata. Anfractus cingulis 4, granoso-
crenatis (nisi in anfractu ultimo adultarum, ubi levia fiunt), et
quinto (vel potius filo suturali) ,minore, minusque elevato,instructi :
c. primum, sepius in adultis pallidius, et deinde quartum, ma-
culis subremotis fulvis vel castaneis, quarum series minores sen-
sim in ¢. secundo, et postremo in omnibus apparent, ornatum ; c.
tertium ac. precedente (utrumque in adultis postremo vix emi-
nens) strid mera, a ¢. sequente, et prominente, sulco lato, divisum.
Carina satis magna utrinque filo, quorum superius (a sulco satis
lato preecessum) crassius est, circumsepta. Basis area media (non-
nunquam pallide fulva) cing. 3-4 granosis punctisque pietis, quie

bihei coarctati pauce, permagne, in adultis albidee. Oss. Our
figure of the adult (f. 35) does not adequately represent the most
striking characteristics, the twin central belt and the broad groove
which succeeds it. Figure 2 is a fair representation of the young
of both this and the succeeding species, which greatly resemble
each other in that immature state which best displays the granular
sculpture.
8. aranutatum (f. 1, 2), Deshayes (as of Lamarck).—T.
valida, depresso-conica, violaceo-albida, vel pallidé ceruleo-viola-
cea: sutura modicé canaliculata. Anfractus cingulis 4 granoso-
crenatis (vel potius subgranosis), ultimo in adultis, ubi levia,
semper, autem eminentia, fiunt, excepto, et preeterea, filo suturali,
in primis subgranoso, instructi: c. superius, latiusque, maculis
brunneis magnis, satisque proximis, conspicué ornatum; c. cetera
subzequalia, et in anf. inferioribus (etiamque in basi) adultorum
maculis minoribus confertim picta; intervalla omnia sulcis latis
equalibus profundeé exarata. Carina, basis, etc., sicut in S. zodile,
nisi, fortasse, dentes plures et vix albidi. Ods. The only adult
specimen known to me did not arrive in time for delineation.
The broad separation of its second and third belts, which do not
become depressed as in zodi/is, easily distinguish it from the ma-
ture of that earlier-known shell. The tints are likewise deeper,
and the spots more numerous. Lamarck’s too briefly described
granulatum, as defined by the synonyms, should rather be the
previous species.
9. Barrpir (f. 48, 49), Handey.—T. depresso-conica, pallidé
fulva; cingula (primo, ultimoque albo, exceptis) maculis obscuris
remotis picta : : sutura perangusta. Anfractus in cingula 5,
sulcis radiata, divisi; 2 prima subzequalia (secundum fortasse pau-
lulum minus) ; tertium ambobus precedentibus simul equum ;
quartum, sulco precessum, primo aliquantum latius; quintum,
sulco lato preecessum, manifesté angustum. Peripherize carina
secunda (suleum satis angustum ? sequens) adeo eminens ut peri-
pheria acutangularis videtur. Crene umbilici magne. Obs.
The umique example of our national museum is not mature, but
has too salient characters to be passed over.
10. prorum (f. 33, 34), Plil.—T. §. purpurato persimilis, sed
pallidé fulva; suture nives et maximé canaliculate ; macule lon-
ginque ; sulci radiantes rudiores ; peripherize sulcus inferior haud
filosus; disci basalis medium Alin serie macularum fulvo-

basalis in junioribus fere pliciformis. Os. The acquisition, by
Mr. Taylor, of all the original specimens of Sodaria, described by
Hinds, from Sir K. Belcher’s collection, has enabled me to identify,
by a long chain of connecting links, the immature fragilis of that
naturalist with the adult pictum of Philippi. The type of the
former was sharply carinated, nearly white, with the fourth belt
continuously and the first interruptedly brown; the prominent
radiating riblets of the white lower disk are obscurely cut towards
the umbilicus by a faint spiral groove; the umbilical teeth are
smaller and more numerous. ‘The mere fry are not unlike the
top of 8. quadriceps, but the great length of the third row of
grains distinguishes them. The adult appears to have been known
to both Seba (iii. pl. 40, f. 41, 42) and Chemnitz (f. 1694,
copied in Kuster’s edition, Sol. pl. 2, f. 4), although I dare not
positively pronounce upon their somewhat rough drawings.
11. Cuminetr (f. 44, 45), Hanley.—T. subdepresso-conica,
albida seu pallidé fulva, infra suleum spiralem zon lata subma-
culosd picta: dimidium inferius anfractuum majorum seriebus 3
macularum linearium brunnearum ornatum. Anfractus sulcis
(nisi labrum versus) subconfertis radiati, et suleo unico spirali
infra cingulum album (margine superiore brunneo submaculoso (?)
passim ornatum) superneé instructi; pars inferior ares medi
costellis tenuibus obsoleté cincta: cingulum marginale (seu infe-
rius) nullum. Carina parva, angusta, brunneoque maculata.
Basis albee area media, tantum umbilicum versus modicum et crenis
rufis permultis munitum punctis picta: cingulum infraperipherale
procul a carina, angustum, tantum obscuré maculatum.
12. purpuratum (f. 7, 8), Hinds.—T. seepius depresso-conica,
striis confertis radiata. Anfractus suturé angusta divisi, sulcis 2
(quorum superior fortasse est major) cincti, pallidé ceerulescente-
purpurei, maculis rufis (seepe flammas simulantibus) ad carinam,
cingula, zonas 2 superiores anf. ultimi penultimique plerumque
etiam ad cingulum anf. caeterorum primum (aliquando omnino
album), ubi, sicut in cingulo suprasuturali macule magne fiunt

nonnunquam filosam preecedens, satis latum (seepe latius quam
ipsa carina). Basis media maculis brunneis undatis satisque
magnis (aliquando vel concurrentes strigas radiantes formant, vel
oritur series interveniens) utrinque marginata. Sulcus inter cin-
gula basis externa satis latus, unifilosus. Crenze umbilici, nun-

area of the lower disk.
13. perpix (f. 17, 18), Hinds.—T. depresso-conica, sulcis
subcontiguis (corpore levi excepto) subobsoleté radiata, spiraliter
unisulcata. Anfractuum zona superior candida, maculis ferrugi-
neis (seepiusque remotis) ornata: area infra suleum profundum
sublatum pallida, aliquando maculis linearibus ferrugineis (sepe
autem obscuris) superné marginata. Cingula peripherie peran-
gusta, arcté tenuiterque crenata, et, cum cingulo suprasuturali
cingulisque externis disci inferioris, albo et ferrugineo articulata.
Sulcus peripherie profundus, in latitudine cingula vicina emulans,
haud filosus. Aree basalis medium sulcis radiatum, pallidé albo-
purpurascens, tantum ad marginem interiorem obscure macula-
tum. Crenz umbilici vix unice ampli, candid, permulte.
14. Dunxert (f. 29, 30), Hanley.—T. conica, baud multum
depressa, seepe trochiformis. Discus superior sicut in 8. perdice,
sed magis fulvus, et nonnunquam maculis linearibus parvis dis-
tantibus subbrunneis, in seriebus spiralibus paucis, subobsoleté or-
natus; cingula, etiam, latiora multoque confertius crenata, macu-
lis brunneis confertioribus magisque conspicuis, picta: carina lata.
Discus inferior (in exemplis pulchrioribus) sicut in S. purpurato :
area media lineis nonnullis brunneis interruptis aliquando cincta :
sulci radiantes conspicui. Crenze umbilici magne, plerumque
brunnee. Ods. The keel is peculiarly broad below. The exte-
rior spiral sulci of the lower disk are almost cancellated in imma-
ture examples.
15. taviearum (f. 21, 22), Lamarck.—T. subdepresso-conica,
inferné albida, superné violaceo pallido magis minusve tincta,
luteo-tuscescente vel fulvo notata. Anfractus sulcis profundis
2 (preeter eum qui cingulum elevatum super suturam modicé
canaliculatam preecedit) cincti; vittee superiores 2 eequales, tertia
aliquantulum latior, cingulum angustissimum. Vitte apicem
versus obliqué decussate, labrum versus levigate ; utraque ma-
culis informibus, prima magnis et distantibus, secunda et tertia
parvis et seepius spiraliter linearibus, notata. Peripherie cingula
subeequalia; sulcus ejus superior subangustus, inferior latus,
haudque filosus. Area media basis magis minusve levis, mar-
ginem exteriorem versus maculis magnis irregulariter circum-
scripta, alibi lentiginibus linearibus parvis frequentibus cincta.
Crene umbilici coarctati magne, plerumque albide, aliquando
ferruginee. Obs. The edge of the pillar is apt to be crenated,
and the umbilical wall is usually spirally striated in fine examples.

Reever (f. 9, 10), Handey.—T. fulvo-carnea, vel livido-
carnea, in utroque anfractu maculis parvis saturate fulvis in serie-
bus 5-6, ordinatis, cincta; striis, denique obsoletis, contiguis
tennibus transversim obliquis radiata; sutura haud canaliculata.
Anfractus haud celeriter expansi, cingulo suprasuturali (nonnun-
quam duobus) quod seepius est albidum et fulvo-brunneo remote
articulatum, infra sulcum spiralem latum minimé profundum ornati,
alibi inconspicue (sulco infra zonam primam excepto) spiraliter
sculpti. Basis et peripheria fere ut in S. /evigato, sed cingulum
proxumbilicale (cum crenis parvis permultisque umbilici coarctati)
confertim maculosum. Os. The upper disk of this shell, whose
apex is of a dark liver colour, reminds one a littie of Zrochus
zizyphinus; upon the lower there is an obsolete spiral sulcus
beyond that which bounds the proxumbilical belt. The only
specimen known to me is an elevated abnormal form, and I think
both the conoidal shape and the lower suprasutural belt result
from the coiling of the (7) whorls upon the carial belt instead
of, as usual, upon the groove above it. The central rows of
spots are somewhat linear. 8. Zevigatum and S. purpuratum are
its nearest congeners.
17. ruticrnosum (f. 13, 14), Hinds.—T. depresso-conica,
sulcis subremotis (in ultimo anfractu obsoletis) radiata; sutura
angusta, profunda. Anfractus im medio pallidi et strigis brun-
neis latis obliquis undulati. Vitta super suleum spiralem unicum
angustum profundum satis lata, brunnea, leviter autem albo
infra marginata. Cingula brunneo et albo articulata; c. supra-
suturale angustum ; sulcus inter c. peripherale latum et carinam
angustam fulvo-maculatam perangustus et crassé unililosus.
Basis planulata: sulcus perangustus, infra carinam filosus : area
media pallida versus umbilicum satis amplum (cujus crene per-
multee sunt et rufo-fuscee) maculis subrhombeis subcontiguis
brunneis satis arcté ornata. O/s. In the only mature individual
I have yet seen, the umbilical wall is adorned with spiral brown
lines, and the characteristic streaks, which do not reach to the
encircling sulcus, are converted into two interrupted zones on the
earlier volutions.
18. Hantryt (f. 15, 16), Sowerty.—‘*'T. depressa, supra conica,
infra lenticularis; imter anfractus sutura profunda; anfractus

features of this beautiful shell are the brown-reddish flashes of
colour, in which it resembles S. fuliginosum, and the rounded
lenticular base, in which it differs from all species of the Architec-

me. Philippi adds that the colourless specimen sent lim by
Seacchi,in tolerable condition, exhibited two scarcely raised threads
between the belts; that its keel, although acute and very de-
pressed, was rounded off at the angle; that its convex base (a
little concave, however, before the extreme margin), rayed with
dichotomous folds, a continuation of the umbilical teeth, was
otherwise smooth (the specified sculpture excepted) ; that its um-
bilical ridge projected considerably inwards; and that its mouth
was very depressed, and very sharply angulated at the outer lip.

translucent in texture) of this beautiful fossil at present known,
the keel protrudes downwards, the ribbed portion of the base is
convex, and the belted area is somewhat concave. ‘The absence
of an umbilical belt is a striking peculiarity.

—Acapuleo, 6-4 lin.
The author remarks that the description of Hebert: would mostly apply to it, but
that shell appears to have a coarser granulation, and three umbilical channels. The
belts, of which there are 4 upon each turn, and 6 upon the almost flat base, are but
slightly granulated. The mouth is rounded by the obsoleteness of the keel. There
are 2 ridges in the open umbilicus, the outer of which is the spiral keel whose white
grains gleam so conspicuously within it.
Menke, erudite, but ever obscure, has quoted two figures of perspectiviunculus
(Geve, f. 275, and Chemn. f. 2708, 9) for his Euomphalus radiatus (Zeit. Malak. 1850,
p- 170), ashell referred to that species by Carpenter, yet whose umbilicus suits not the

Obs. A very long series of specimens has induced me to unite
forms that at first I should scarcely have hesitated to rank as dis-
tinct. ‘The species varies greatly as to shape, breadth of sulci,
prominence of the belt, and diversity of colour and pattern: the
umbilicus is always more contracted in the Trochoid than in the
Rotelliform examples. In one specimen only have I descried
two umbilical ridges. As a general rule the depressed specimens,
if dark, come from the Sandwich Isles, if with much white from
Annaa; the latter when conoid from Borneo, the former if conoid
from the Society Isles: the flammular are chiefly from the Philip-
pines and the Red Sea. Pdanulata (f. 63) is perhaps distinct.

(nonnunquam, autem, ultimum solum) sunt articulata, sulcis

Obs. In the more characteristic examples, the bands upon the
base are pale, and the sulci chestnut; the intervals between the belts,
too, are not threaded: other specimens, however, show a very
narrow thread beneath the fourth, fifth (which with the ninth, are
the broadest), and the sixth belt.
Menke has so imperfectly described both this and Athiops,
that it would have been impossible to have determined his species,
had it not been for their republication by his friend Philippi.
The 8. xubilum of Menke (MSS.), founded on a single worn
specimen, was not improbably a variety of this polymorphous
species. It is said to differ in being much smaller, having an ad-
ditional umbilical ridge, and in the sulci being narrower, pricked,
and more shallow. Philippi thus describes it (Zeitschrift Malak.
1848, p. 170 ):—

Of the following species, ascribed rightly or wrongly to this
genus, I am unable to procure examples.
rricinctum, Phil. in Kuster, ed. Chemn. Solar. p. 36.—“ T. mi-
nima, albida, fusco radiata ; anfractibus teretibus, sutura profunda
divisis, transversim corrugatis ; cingulis 2 in anfractibus superiori-
bus, 3 in anfractu ultimo, supremo striis elevatis a sutura radian-
tibus secto; umbilico aperto, pervio, marginato, striis elevatis ra-
diantibus, sulcisque concentricis granulato-decussato. Gabon, in
Guined. 13 lin.” The unfigured specimen was in the collection
which M. Llargilliert bequeathed to the city of Rouen. From
its minuteness and the peculiarity of its umbilicus its generic lo-
cation may be doubted.
impLexuM, Mighels, Proc. Bost. N. H. ii. p. 22 (copied by
Phil. in Kust. ed. Chemn. Solar. p. 37).— Depressed, subdiscoid,
greyish-white, with a few brown spots; whorls 3, flattened, with
5 rounded revolving ridges on each, intersected by numerous,
impressed, transverse strie; aperture circular; umbilicus large
and deep. 4; inch. Oahu.” The description (in English only)
is too brief for the determination of a species : it would tolerably
suit a young dorsuosum.
pELPHINULOIDES, LD’ Orb. Moll. Cuba, p. 67 (copied in Phil.
Kuster, Solar. p. 35), pl. 19, f. 21-24.—“ T. trochoidea, trans-
versim costata, alba; spira elevata, conica; anfractibus convexis,
supra 4 costatis, subtis 8 (costatis) ; umbilico lato, non canali-
culato, costato, interné subcrenulato; apertura rotundata. 4
* In the Zoology to Humboldt and Bonpland’s Voyage (ii. p. 269), I find a spe-
cies described (said to be almost the living analogue of the fossil mil/egranum) which
probably belongs to this section.
S. eranosum, Valence. ‘‘'T. conoidea, subdepressa, infra rotundata, gibbosa, peni-
tus ubique granosa, rufo variegata: umbilico coarctato, dentato. Acapuleo. 9-4
lin.” The shape is said to be less conic than in granulatum, and the whorls, each
having 5 or 6 granulated belts, the keel alone being smooth, to be more convex ;
the colouring to be reddish with conspicuous chestnut spots along the course of the
spire, and red spots, paler than the others, near the white keel ; the base, which is
granulated throughout, to be encircled by 5 rows of slightly rounded tubercles: the
umbilical teeth to be strong and white.
SOLARIUM. 245
mill.” The figure neither displays the trochoid shape nor the
elevated spire attributed to the species. If a Solarium, it is an
abnormal one. ‘The type is not recorded as present in the British
Museum catalogue of D’Orbigny’s collection.
pLaNnorsis, Blainy. Dict. Sc. Nat. xlix. p. 411.— “Small, white,
nearly flat, discoid, with scarcely tuberculated spirai sulci and trans-
verse striz. The very open umbilicus with a row of tubercles, the
last of which is notched. Mouth rounded.” I cannot pretend
to identify a species from so inadequate a definition, the original
of which is in the French language.
EGENUM, Gould, Proc. Bost. N. H. i. p. 84; i Wilkes
Eaploring Expedition —“T. parva, ovato-conica, exalbida, sub-
margaritacea; spira anfractibus 6 convexis, liris acutis 4 cinc-
tis, posterioribus granulatis ; basis convexiuscula, perforata ; um-
bilico scalariformi, ad ambitum acuto, crenulato ; apertura cir-
cularis, labiis fere continuis. ;2;-+ inch.” Gould remarks that it is
not strictly a Solarium; yet nearer one in aspect than a Zrochus,
closely resembles S. deadbatwm, and in size, form, and colour, re-
minds one of Margarita obscura.
BICARINATUM, Phil. in Kust. ed. Chemn. Sol. p. 23, pl. 3, f. 14.
—“ TT. depressa, strigis albis et nigris alternantibus picta: an-

much doubt its bemg a member of this genus.

Arcutra, Costa, Mem. Acad. Napoli, \844.—“'T. orbiculato-
plana, albo-flavidula, longitudinaliter sulcata, transversim crenu-
lata; anfractibus supra carinatis; umbilico amplissimo, denticu-
lato.” 74 mill. Tarentum. It is further said to be flat and
angular above, with a rounded mouth, and only fine denticulations
at its umbilicus. Possibly a form of séramineun.
The Zrochus perspeculatus of Meuschen was a Solarium: it is
thus inadequately described in the ‘ Zoophylaceum Gronovianum ”
246 SOLARIUM.
(p. 823, n. 1485) :—* Testa crenato-umbilicata, convexa, obtusa,
marginata, longitudinaliter crenato-striata.” It is said to come from
the Indian seas, and only to differ from his perspectivus (the syno-
nymy of which includes ¢roch/eare, and almost all the then known
allied species) by its contiguous, longitudinal, crenated striz.
Genus BIFRONTIA, Desh.
Gen. Char. Discoidal, planorbular, paucispiral, keeled above
and below ; body-whorl slightly detached; apex sunken; mouth
squarish; no umbilicus; operculum externally conical, truncated at
the top.
1. Zancima (Bif. f. 1, 2), PAid.—T. parva, tenuis, discoidea,
fulva (seepius colore saturatiore et pallidiore alterné nebulosa),
supra plano-concava, infra concava. Anfractus pauci, laxati
(plerumque ad aperturam, apicemque, disjuncti), cingulo confertim
squamoso-granoso, superne et inferné utrinque marginati; alibi
leves, nitidi, et (are& latissimé subpland inter peripheric carinas
2 except) convexi. Cingulum interius multo minus; c. exte-
rius, in anfractu ultimo carinam valde eminentem simulans.
Apertura subquadrata; labium continuum, haud reflexum, sculp-
ture expers. Obs, None of my specimens exhibit the peripheral
threads delineated (pl. 28, f. 11a), but not described, by Philippi.
The operculum is of a truncated conic shape and subconcentri-
cally lamellar; it is very like that of Zorinza. ‘The entire shell is
enveloped by a dull epidermis, which at times is so wrinkled, that
the periphery seems spirally striated. One or both of the keels
is here and there obscurely cloven.

MONOGRAPHS OF THE GENERA
CYCLOSTREMA, ADEORBIS, ann TEINOSTOMA.
By Artnur Anpams, R.N., F.L.S., erc.
Genus CYCLOSTREMA, Warryatt.
Shell orbicular depressed, widely umbilicated; spire small;
whorls rounded, spirally ridged, radiately ribbed or cancellated.
Aperture not pearly within, orbicular; peritreme continuous,
acute.
This genus with its allies, which we have here, for the sake of
convenience, considered in the light of subgenera, together with
the genus Adeordis, appear to constitute a peculiar group of Zro-
chids, the shells of which may at once be distinguished by the
absence of pearly nacre in the interior of their apertures. The
genus V2trined/a, of C. B. Adams, seems more nearly related to
the Seisswrel/a race than to Adeorbis.
1. cancetnata (pl. 255, f. 5, 6), Marryatt.—Testa alba, lineis
longitudinalibus et transversis elevatis decussantibus inde cancel-
lata; apertura labiis cancellatis; cancellis transversim striatis.
Obs. This beautiful shell, procured by Captain Marryatt from
West Indies, and made the type of a peculiar genus at the sug-
gestion of Dr. Leach, differs from the other species of the genus
im being plicate above and below a peripheral keel ; the specific
name is hardly characteristic. We have reproduced the original
description.
2. tavis (pl. 255, f. 3, 4), Kien.—Testa orbicularis, nivea ;
spird depressi; anfractibus transversim costellatis; costellis re-
gularibus, superis, distantioribus ; interstitiis leviter concavis ; su-
turis profundis subcanaliculatis ; labro simplici; umbilico per-
amplo. Obs. The Cyclostrema diatretum, Gould, is the same as
this species, which has been considered by Reeve as the Zwrbo
VOL. LI. 21
250 CYCLOSTREMA.
niveus of Chemnitz. That shell however appears to be accu-
rately represented by our Zudiola nivea, f. 35 and 36.
8. Reevrana (pl. 255, f. 9, 10), Hinds.—Testa orbicularis,
subdiscoidea, mutica; spira depressiusculd ; anfractibus convexis,
longitudinaliter carinulatis ; carinulis numerosis, superis, distanti-
oribus ; interstitiis liris obliquis corrugato-clathratis ; labro sim-
plici; umbilico peramplo. Ods. In sculpture this perhaps is the
most beautiful species of the genus, although some others may
equal it in elegance of form. It is dedicated to a voyage-natu-
ralist who was well qualified to appreciate the beautiful in shells.
4. ctncuLirura (pl. 255, f. 13, 14), 4. dd.—Testa orbicu-
laris, nitida; spiré depress’; anfractibus rotundatis; carinulis
transversis, acutis, eequidistantibus ; interstitiis (sub lente) tenuis-
simé longitudinaliter striatis; apertura subcirculari, supra sub-
angulata; umbilico mediocri. Ods. This is a solid species with
wide-apart conspicuous concentric ridges, the intervals being, in
very fresh specimens, finely concentrically striated. In good con-
dition it is almost semiopaque and has a glossy appearance.
5. micans (pl. 255, f. 7, 8, 27). —Testa turbinata, alba, nitida;
anfractibus convexis, longitudinaliter oblique costellatis, transver-
sim carinulatis ; carinulis nodulosis ; umbilico mediocri ; apertura
circulari ; peristomate continuo, subincrassato. Os. This is the
Cyclostrema pulchellum of Dr. Dunker, who obtained it from
Japan. The author has likewise found the species abundantly in
the inland sea of that country, but had previously described the
species from the Philippine Islands.
6. ancutava (pl. 255, f. 1, 2), A. Ad—tTesta orbicularis,
discoidea ; spirA depressi ; anfractibus transversim costellatis ; cos-
tellis regularibus, eequidistantibus ; interstitiis tenuissimé striatis ;
anfractu ultimo biangulato, supra costellato, in medio plano, infra
costellato ; apertura subangulati; peritremate interrupto; um-
bilico permagno. Ods. This is a very fine and elegant species,
brought by Mr. Cuming from the prolific islands of the Pinhp-
pine Archipelago.
7. sutcata (pl. 255, f. 11, 12), A. Ad—Testa orbicularis,
discoidea; spird planiusculi; anfractibus convexis; costellis
transversis, confertis, regularibus, interstitiis ; profundé sulcosis ;
suturis profundis, canaliculatis; umbilico patulo; peromphalo
levi. Obs. This species is common in the China Sea; Mr.
Cuming has found it in the Phihppines, and the author has met
with it rather abundantly in the seas of Japan.
CYCLOSTREMA. 2511
8. Brant (pl. 255, f. 25), Fisch.—Testa crassiuscula, compla-
nata, orbicularis, alba, laté umbilicata, supra concentricé et validé
costata (costis 5), subtus nitida, obsolete suleata, compressa, con-
cava; anfractibus 44, subplanulatis, ultimo acuté bicarinato,
inter carinas levi; apertura rotundi; margine dextro arcuato,
supra minuté sulcato, infra angulato. Ods. A singular species,
described by M. Fischer from Guadeloupe, with the peripheral
keel, causing an angular projection at the lower part of the
peritreme.
9. VerrEauxtt (pl. 255, f. 17, 18), Fiseh.—Testa crassiuscula,
complanata, discoidea, alba, nitida, laté umbilicata, concentricé
minuté sulcata; anfractibus 4, subplanulatis, ultimo permagno
dilatato, carinis tribus munito, 1 superiore, 1 media, area plana
separatis, et 1 inferiore minore ; aperturd rotundatd, transvers4 ;
margine dextro elongato, carinis productis tricuspidato, subin-
crassato. Obs. This species is remarkable for the points of the
peristome, which are formed by the prolongation of the keels, and
which cause it to somewhat resemble in form the genus Zeino-
stoma.
10. rornata (pl. 255, f. 19, 20), 4. dd. Testa orbicularis,
turbinato-discoidea ; spira elatiuscula; anfractibus convexis, cos-
tellis concentricis elevatis eequidistantibus ornatis ; interstitiis sim-
plicibus; suturis profundis; umbilico profundo. Obs. This
species very closely resembles in sculpture and general appear-
ance C. sulcata (f. 11, 12), but its form is different, the spire
being more elevated, the whorls more rounded, and the umbilicus
smaller.
1]. Scurammei (pl. 255, f. 26), Hisch.—Testa planorboidea,
compressa, orbicularis, corneo-alba, aperté umbilicata; costis ra-
diantibus validis; carmé mediana insertione costarum cristata, et
carinis 2 (1 superiore, 1 inferiore, obsoleté nodosis) ornata; an-
fractibus 3; apertura rotundaté; margine dextro acuto. Obs.
This species has the aspect of a small Ammonite, or a Planordis
eristatus, with three rows of spines.
12. crnevuata (pl. 255, f. 23, 24), Dér.—Testa subdiscoidea,
lactea, umbilicata; spird depressd, anfractibus quaternis, subito
crescentibus, tricarinatis instruct’; sutura incisi; apertura sub-
rotundaté. Ods. A very neatly formed carinate species, figured
from a specimen obtained by the author in Japan, and which
seems to represent very nearly the figure of C. angulata figured
by Dr. Dunker in his ‘ Mollusca Japonica.’
13. excavata (pl. 255, f. 15, 16), Cor.—Testa orbiculato-
252 DARONIA.
depressa, solidiuscula, alba, late et profundé umbilicata; spird
prominulé; anfractibus subconvexis, supra leevibus, infra concen-
tricé sulcatis, umbilico carina promineute circumcincto. Obs. A
species of simple sculpture, of very elegant form, described by
P. P. Carpenter from the seas of China.
14, anaetypta (pl. 255, f. 28, 29), 4. dd.—Testa depresso-
turbinata, alba, nitida, profundeé et late umbilicata; spira elatius-
cula; anfractibus rotundatis; carinulis concentricis acutis crenu-
latis ; interstitiis lineis radiantibus laté clathratis ornatis, basi cari-
nulis confertis denticulatis instructis; umbilico magno, intus
radiatim lirato; apertura orbiculari, margine crenato. Ods. A
very beautiful, richly-embossed shell, with a style of sculpture very
much resembling that of C. Reeviana, but the form is more tur-
binate than in that pretty species.
15. ammonoceras (pl. 255, f. 21, 22), 4. dd.—Testa de-
presso-turbinata, discoidea, late umbilicata, alba, solida, concen-
tricé striata, radiatim costata ; costis tenuibus, subdistantibus, ad
suturas evanidis ; anfractibus rotundatis; apertura circulari; pe-
ritremate continuo; labio callo parvo resupinato instructo. Cds.
The only species resembling this is C. Schrammi, Fisch., from
Guadeloupe, which has the same remarkable Cornu-Ammonis
appearance, but the whorls of which, instead of being rounded,
have two concentric keels which gives the species, says M. Fischer,
the appearance of Planorbis cristatus, with three rows of spines.
16. Brrorcata (pl. 255, f. 30, 31), 4A. dd.—Testa parva,
subdiscoidea ; spird depressi, albida, laté umbilicata; anfractibus
3, subplanulatis, ultimo anticé dilatato, supra levi, infra con-
centricé striato, ad peripheriam liris duabus validis transversis in-
structo; apertura circulari; peritremate continuo, simplici. Ods.
This little species differs from any of those described, and may
easily be recognized by the double keel which surrounds the
periphery.
Subgenus Daronta, A. Ad.
Shell orbicular, discoidal, evolute, spire depressly concave ;
whorls rounded, more or less disunited ; aperture circular ; peri-
treme continuous. Oés. I have considered it advisable to keep
this as a distinct subgenus, on account of the very peculiar form
and sculpture of the shell. The type species greatly resembles
Ammonia spirula, L., or Spirula australis, Lam.
1. spiruta (pl. 255, f. 32, 83), 4. dd.—Testa orbicularis, dis-
coidea, evoluta; spira depresso-concavé; anfractibus rotundatis,
TUBIOLA. 253
primis contiguis, ultimo distincto, transversim costulatis ; costellis
subconfertis, eequidistantibus ; interstitiis tenuissimé- longitudi-
naliter striatis; apertura circulari; peritremate continuo. Ods.
The figure is from a beautiful perfect specimen, picked up by Mr.
Cuming on the sands in one of the Philippine Islands. It is at
present unique in his unrivalled collection.
2. cycLorrna (pl. 255, f. 34), 4. dd.—Testa discoidea, orbicu-
laris, vix evoluta; spira pland; anfractibus rotundatis, contiguis,
minuté striatis, simplicibus; apertura circulari, expansiuscula ;
peritremate continuo. Oés. This species was picked up on the
sands at Kino-O-Sima, in Japan, by the author. It is not quite
perfect, but is very distinct from D. spiruda.
Subgenus Tustoxa, A. Ad.
Shell subevolute or loosely enrolled ; whorls rounded, simple,
concentrically striated; aperture subcircular; peritreme continuous;
margin acute, entire. Ods. This little group resembles somewhat
Daronia, but the texture and aspect more approximates the genus
Adeorbis.
1. nivea (pl. 255, f. 35,36), Chemn.—Testa ovato-orbicularis,
nivea, tenuis, semipellucida; spird depress; anfractibus rapidé
crescentibus, convexiusculis, concentricé creberrimé liratis lineis-
que incrementi decussatis; suturis profundis, subcanaliculatis ;
anfractu ultimo magno, anticé dilatato, ad peripheriam rotundato,
ad peritrema contiguo ; aperturé perobliqua, subcirculari, posticé
angulaté; peritremate continuo, simplici, acuto; umbilico per-
amplo, patulo, perspectivo. Oés. This shell agrees exactly with
the original figure and description of Chemnitz’s Turbo niveus.
The Delphinula nivea, Reeve, is the same as D. levis, Kien., and
C. diatretum, Gould.
2. CORNUELLA (pl. 255, f. 37, 38), A. dd.—Testa subdiscoidea,
ovato-oblonga, tenuis, sordidé alba, laté umbilicata ; apice elato ;
anfractibus 34, rapidé accrescentibus, rotundatis, ultimo ad peri-
trema soluto, striis incrementi ornato; apertura perobliqua, trans-
versim ovata; peritremate continuo, acuto, integro, dilatato. Ods.
In this species the whorls are disunited as in Daronia spirula, but
they are not rolled on the same plane as in that group.
3. pivisa (pl. 255, f. 39, 40), J. Adams.—Testa turbinata,
subevoluta, alba, tenuis, laté umbilicata, infra spiraliter costellata ;
apertura magna, circulari. Ods. Shell “pure white, lower disk
spirally striated or costellated, aperture large and circular, um-
bilicus capacious.”’
254 MORCHIA.
Subgenus Microragca, 4. Ad.
Shell globosely turbinate, widely umbilicate, somewhat porcel-
lanous, radiately rugosely plicate; sutures channelled; whorls
crenulate at the sutures. Aperture semicircular ; peritreme con-
tinuous ; inner lip thickened, arcuate; outer lip with the margin
thickened; umbilicus crenulate. Ods. These very peculiar little
shells are closely allied to Morchia, but the last whorl does not
embrace the others, as in that form, and the umbilicus is narrower
and crenulated at the margin. The outer lip also is varied.
1. cRENELLIFERA (pl. 255, f. 41, 42), 4. dd.—Testa globoso-
turbinata, laté umbilicata, alba, solida, semiopaca, longitudinali-
ter plicato-rugosa ; suturis canaliculatis ; anfractibus ad suturas
crenulatis ; apertura subcirculari ; labio incrassato, arcuato ; um-
bilico margine crenato, Ods. In the general form and crenate
suture this curious little species resembles Isanda coronata, A.
Ad., which, however, on account of the polished porcellanous
character of the shell, 1 have referred to the family Uméonide.
Subgenus Morcuta, 4. Ad.
Shell obliquely ovate, depressed, widely umbilicated, convex
above, flat beneath ; whorls rapidly increasing, the last dilated,
ascending, and embracing the other whorls as far as the apex.
Aperture oblong, oblique, somewhat horizontal, dilated below,
narrowed above; peritreme continuous, thickened. Ods. This
curious little genus resembles Zeinostoma in the fact of the last
whorls embracing the others, but the base is not covered with
a callus, and the mouth is not anteriorly produced.
1. osvorura (pl. 255, f. 43, 44), A. Ad.—Testa obliqué
ovata, alba, depressa, laté umbilicata ; anfractu ultimo ad_peri-
pheriam angulato, striis incrementi confertis ornato, ad suturas
corrugato-crenulato ; umbilico patulo, Ods. This shell appears
to be rare in Japan. I only obtained two specimens; one at
Tsu-Sima, in 26 fathoms, and the other at Takano-Sima, in shell-
sand. It is a curious form, with an open umbilicus, and with the
last whorl encroaching upon and nearly covering the others, as it
does in Neritula and Teinostoma.
Genus ADEORBIS, Searles Wood.
Shell depressly conical-orbicular, deeply umbilicated ; whorls
flattened, spirally striated or smooth, the last more or less angu-
ADEORBIS. 2b
late at the periphery. Aperture not pearly within, transversely
ovate; inner lip sinuated; peritreme interrupted; outer lip
arcuate, simple, acute. OJs. The principal difference between
this genus and Cyclostrema consists in the more or less trochi-
form appearance of the shell, in the whorls being either smooth
or spirally striated, and especially in the peritreme not being cir-
cular and continuous.
1. suBcartnata (pl. 256, f. 7), Montag.—Testa suborbicu-
laris, depressa, laté umbilicata ; anfractu ultimo ad peripheriam
subcarinato, liris quatuor spiralibus ornato; aperturé rotundato-
ovata; labio subreflexo, labro acuto. Ods. This somewhat rare
British species is the type of the genus; the animal, however,
does not appear to have been hitherto studied.
2. pLana (pl. 256, f. 3, 4), 4. Ad.—Testa orbicularis, dorso
plano-convexa ; spira depressé ; anfractibus planis, supra transver-
sim striatis, infra leevibus ; aperturé subcirculari, supra angulata ;
umbilico peramplo, anfractibus intus conspicuis. Ods. A large
(for the genus) species, with a very flat spire and with the whorls
concentrically finely striated.
3. ELEGANS (pl. 256, f. 1, 2), 4. Ad.—Testa orbicularis, dis-
coidea, tenuis, semipellucida; spira depress ; anfractibus rotun-
datis, transversim omnino striatis ; suturis distinctis ; apertura
subcirculari, supra angulaté; umbilico peramplo. Ods. A beau-
tiful semipellucid species, remarkable for the extreme elegance of
its form; the aperture is peculiarly angulated at the fore part.
4, PLANORBULA (pl. 256, f. 5, 6), 4. Ad.—Testa orbicularis,
planorbula ; spira depress ; anfractibus levibus, rotundatis ; su-
turis distinctis; aperturé subcirculari, supra angulata ; umbilico
permagno, patulo. Oés. The aperture in this cyclotiform species
is circular and somewhat dilated, yet the sum of all the characters
shows it to belong more properly to Adeorbis than to any other
genus.
5. nitipa (pl. 256, f. 9,10), A. Ad.—Testa orbicularis, levis,
tenuis, nitida; spird elatiusculA ; anfractibus prope suturam sub-
angulatis; suturis profundis, subcanaliculatis ; apertura subcir-
culari, supra angulataé ; umbilico magno, peromphalo angulato,
acuto. Obs. The principal peculiarity of this species is the an-
gular keel round the umbilicus; the whorls and aperture are
more rounded than usual and the surface of the shell is polished.
It may possibly belong to the genus Cithna, A. Ad.
6. Apamsit (pl. 256, f. 8), Hiseh.—Testa translucida, corneo-
256 ADEORBIS.
alba, nitida, complanata, suborbicularis, umbilicata; supra minu-
tissimé et concentricé striata, subtus leviuscula; anfractibus 34,
rapidé accrescentibus, ultimo compressiusculo, non carinato ;
apertura subovata, parum transvers4 ; margine dextro tenui, fragili.
Obs. A pellucid, shining, rather solid species, very finely concen-
trically striated.
7. Aneast (pl. 256, f. 37, 38), A. dd.—Testa valde depresso-
conica, laté umbilicata, alba, tenuis, semipellucida; anfractibus
rapide crescentibus, ultimo magno convexo concentricé striato, ra-
diatim obsoleté plicato, ad suturas crenulato, ad peripheriam
acuté angulato et concinne crenato, ad basin radiatim corrugato-
plicato; apertura semiovata; labio rectiusculo, acuto; labro
posticé ascendente. Ods. This is the largest and most beautiful
species of Adeorbis yet discovered. It was found by Mr. G. F.
Angas in Coodgee Bay, outside Port Jackson Heads, on the
sand.
8. Stnensts (pl. 256, f. 21, 22), A. Ad.—Testa discoidalis ;
spira prominula, alba, subporcelland, opaca, striis incrementi ra-
diantibus et lineis spiralibus transversis decussata; anfractibus
regulariter crescentibus, ultimo ad peripheriam obtuse angulato ;
umbilico patulo, perspectivo, margine carinato ; apertura qua-
drato-orbiculari ; labro mediocri. O%s. This is a rather large
opaque-white species, having very much the aspect of Hthaha,
but there is no trace of an umbilical callus.
9. Jaronica (pl. 256, f. 20), 4. dd.—Testa discoidalis ;
spira depressa ; alba, nitida, tenuis, semidiaphana, radiatim striata ;
anfractibus regulariter crescentibus, convexiusculis ; umbilico
patulo, margine valde carinato ; labro mediocri. Ods. The most
common species met with in the seas of Japan, not however cha-
racterized by any remarkable peculiarities either of form or sculp-
ture.
10. cravsa (pl. 256, f. 25, 26), 4. Ad.—Testa discoidalis ;
spird depress; albida, subdiaphana, striis incrementi radiatim
ornata; anfractibus rapidé crescentibus, ultimo ad suturas vix
angulato, ad peripheriam rotundato; umbilico callo, tenui, vix
clauso ; labro producto. Ods. In this species the umbilicus is
partly occupied by a callosity, asin some species of Hthalia.
1]. orpetta (pl. 256, f. 16, 17), 4. Ad.—Testa discoidalis ;
spira planatai; alba, subporcellana, nitida, semiopaca, radiatim
striata, basi transversé confertim sulcata ; anfractibus regulariter
crescentibus, ultimo ad peripheriam rotundato; umbilico patulo,
perspectivo, margine rotundato; labro subproducto. Oés. In
ADEORBIS, 257
this species the umbilicus is open and the peromphalus obtusely
keeled; the whorls are radiately striated.
12. prominuta (pl. 256, f. 23, 24). 4. dd.—Testa discoidalis ;
spira elatiusculA; alba, subdiaphana, nitida, striis incrementi
ornata ; anfractibus rapid’ crescentibus, ultimo ad peripheriam
rotundato ; umbilico mediocri, margine carinato ; labro producto.
Obs. In this species the spire is conical and more raised than is
usual in this genus, and the margin of the umbilicus is keeled.
13. pEpREssA (pl. 256, f. 14, 15), 4. 4d.—Testa discoidalis ;
spira planata; alba, vix opaca, ‘radiatim striata; anfractibus ra-
pide crescentibus, ultimo ad peripheriam rotundato ; basi rugulis
radiantibus ornata; umbilico patulo, margine valde rugoso-cre-
nato; labro mediocri. Ods. This is a very depressed species,
very similar in form to A. plana, but the aperture is more circu-
lar and not so oblique as in that species, and the size also is
much less,
14. parrueuis (pl. 256, f. 35, 86), 4. dd.—Testa ut in 4.
Japonica discoidalis, sed spira elatiuscula ; alba, nitida, semipel-
lucida, radiatim striata; anfractibus regulariter crescentibus,
convexiusculis, ultimo ad suturam vix angulato, ad peripheriam
rotundato ; umbilico angusto, margine carinato ; labro mediocri,
Obs. This ' species has resemblances to several others, but cannot
properly be affiliated to any ; the last whorl is slightly angulated
at the suture, and the margin of the umbilicus is carinate.
15. cornicutum (pl. 256, f. 29, 30), 4. dd.—Testa ovato-dis-
coidalis, tenuis, nitida, subdiaphana, radiatim minutissimé striata ;
anfractibus rapidé crescentibus ; umbilico angusto, margine valde
carinato; labro producto. Oés. An orbicular turbinate thin
species, with shining whorls and a narrow umbilicus.
16. suturatis (pl. 256, f. 27, 28), 4. 4d.—Testa ovato-dis-
coidali; spird prominulé; albida, tenuis, semipellucida, striis
incrementi radiatim ornata; anfractibus rapidé crescentibus, prope
suturas subcarinatis, ultimo ad peripheriam subangulato; suturis
canaliculatis ; umbilico angusto, margine rotundato; labro me-
diocri. Os. A somewhat globose species, with the sutures deeply
impressed.
17. nanuua (pl. 256, f. 31, 32), 4. Ad.—Testa ovata, sub-
convexa, tenuis, semidiaphana, nitida; anfractibus rapide cres-
centibus, convexiusculis, ultimo subventricoso ad peripheriam an-
gulato; umbilico angusto, margine rotundato; labro mediocri.
VOL. III. 2) K
258 THINOSTOMA.
Obs. A smali thin depressed species, very shining and with con-
vex whorls; the margin of the umbilicus is not carinate.
18. carmara (pl. 256, f. 18, 19), 4. dd.—Testa ovato-orbi-
cularis, obliqua, depresso-conoidalis, subdiaphana, alba, laté um-
bilicata; anfractibus convexiusculis, transverse tenuiter striatis,
rapidé accrescentibus, ultimo anticé dilatato, ad peripheriam acuté
carinato ; apertura subtrigonali, anticé angulatd et producta; um-
bilico margine acuto. Ods. The keel at the periphery is marked
and prominent, formimg an acute ledge round the last whorl.
The only other species at all resembling it is 4. subcarinata,
found in the British seas.
19. rrocHuxa (pl. 256, f. 12, 13), 4. Ad.—Testa orbicularis,
depresso-conoidea, profundé umbilicata, supra convexa, infra
plana, alba, semipellucida; anfractibus 54, planiusculis, lenté ac-
crescentibus, suturis marginatis; anfractu ultimo anticé vix dila-
tato, ad peripheriam obtuse angulato; apertura subangulaté,
anticé vix producta; umbilico margine acuto. Oss. This species
resembles a small depressed Zrochus, with a flat base, a some-
what angular periphery, and a deep, rather narrow umbilicus.
20. supaneuxata (pl. 256, f. 33, 34), 4. dd.—Testa ovato-
orbicularis, subdepressa; vertice elatiusculo ; alba, radiatim tenuiter
striata, profunde umbilicata; anfractibus 34, convexiusculis, ul-
timo anticé dilatato, superné obtusé angulato, infra subplano ;
apertura subquadrata, anticé producti; labro supra subangulato ;
umbilico margine acuto. Os. The angular projection of the
whorls is not at the periphery but above it, which causes the
subquadrate form of the aperture; whereas in the British 4. swd-
carinata and the Japanese A. carinata the periphery is carinate,
more or less, and the aperture triangular.
21. prapHana (pl. 256, f. 39, 40), A. dd.—Testa depresso-
orbicularis, alba, tenuis, pellucida, laté et profundé umbilicata ;
spira prominuld; anfractibus 34, subplanulatis, lineis incrementi
ornatis ; anfractu ultimo antice vix dilatato, ad peripheriam rotun-
dato; apertura circulari; umbilico patulo, perspectivo, margine
carinato. Ods. This little pellucid shell is more globose than
the species of Adeordis generally, and the aperture is nearly cir-
cular, with a continuous peritreme.
Genus TEINOSTOMA, A. Ad.
Shell with the spire depressed, polished or spirally sculptured ;
whorls rapidly increasing, umbilical region callous. Aperture
TEINOSTOMA. 259
produced, elongate, remote from the axis; peritreme rounded to-
wards the axis, sometimes angulate at the periphery. Obs.
Perhaps the natural position of this genus is in the family Um-
bonide, the species more nearly resembling those of Lt/alia than
any other group. In form and texture, however, they have very
great resemblances to the shells we have just passed in review.
An examination of the animal must determine the question.
1. votrrum (pl. 256, f. 43, 44), 4. Ad.—Testa orbiculato-
ovata, superné convexa, lactea, opaca, levis, nitida; anfractibus
rapidé crescentibus ; apertura elongata, anticé valde producti et
acuminatéi ; umbilici regione callo magno levi obtecti; labro
supra anfractum penultimum reflexo. Oés. This is the species
which served for the type of the genus as originally constituted.
It is a rare shell from the Philippines, and is in the Cumingian
collection.
2. Carpenrert (pl. 256, f. 41, 42), 4. dd.—Testa orbiculato-
ovata, superné convexa, lactea, opaca, levis, nitida; umbilico callo
obtecto; anfractibus rapidé crescentibus; aperturd producta,
anticé acuminata; labro supra anfractum penultimum reflexo.
Ods. The only shell at all resembling this is 7. amplectans, Cpr.,
which however has a rounded aperture, whereas in this species it
is anteriorly produced. The spire is entirely concealed by the
last whorl, leaving only a minute pit at the apex, and the um-
bilical callus has a slight rimal fissure.
3. CONCENTRICUM (pl. 256, f. 45, 46), 4. dd.—Testa orbicu-
lato-ovata, superné convexa, alba, solida, semiopaca, sulcis con-
centricis confertis concinné insculpta, lineisque incrementi radi-
antibus subtilissimé decussata; anfractibus rapidé crescentibus,
ultimo dilatato, ascendente, alios involvente, vix usque ad apicem ;
peripherid rotundatd, basi convex4; umbilico callo convexo, levi,
omnino obtecto; apertura subcirculari, anticé vix producta. Obs.
A solid convex species, with the surface finely concentrically
grooved, a peculiarity which distinguishes it from any of the
species already known.
4, raptatum (pl. 256, f. 47, 48), A. dd.—tTesta orbiculata,
depressa, superné convexiuscula, basi subplana, semiopaca, alba,
lineis incrementi radiantibus conspicué ornata; umbilico callo
excavato angulato obtecto ; anfractibus subito crescentibus, ulti:o
alios involvente usque ad apicem; apertura depress’, anticé pro-
ducti. Obs. This species is distinguished by its depressed form,
and the conspicuous radiating lines which proceed from the axis
towards the periphery. The callus covering the umbilicus pre-
sents a sharp angular excavated edge near the inner lip.
260 CALCEOLA.
5. Lucipum (pl. 256, f. 49, 50), 4. dd.—Testa obliqué ovata,
depressa, superné convexa, inferné planiuscula, alba, levis, pel-
lucida, striolis incrementi obsoleté radiata; umbilico callo plano
subcirculari opaco obtecto ; anfractibus rapide crescentibus, ulti-
mo ascendente, alios involvente usque ad apicem; aperturd sub-
horizontali, depress, antice producté. Ods. This species differs
from the others already described in beg smooth and pellucid;
the last whort is also considerably more dilated anteriorly.
6. ampLecrans (pl. 256, f. 51, 52), Cor.—Testa parva, alba,
planata, laevis, peritremate rotundata ; callositate spirali, umbilicam
tegente, labium versus subplanati, supra parietem intus suturam
decurreute ; apertura rotundati; labro supra anfractum penulti-
mum reflecto; sutura haud impressi. Ods. In this species the
aperture is produced and angular, the callus covering the umbi-
lical region is very large and thick, and the shell is very flat
above.
7. susstriatum (pl. 256, f. 53, 54), Cor—Testa minima,
planata, opaca, alba, subnitente ; striolis spiralibus, prope suturam
impressam monstrantibus ; callositate angustissima, longiore, circa
rimam umbilicalem gyrante, prope labium vix planato; apertura
rotundatd; labio solido, anfractus penultimos haud amplectante.
Obs. There are a few spiral strie near the suture in this species,
the callosity is very long and narrow, and the aperture is nearly
circular.
Subgenus Catcrortna, A. Ad.
Shell neritiniform, oblong, depressed; spire small; whorls
rapidly increasing, umbilical region callous; aperture semicir-
cular; inner lip with a large wide callus, covering posteriorly the
umbilicus ; margin of the callus straight, simple.
1. positta (pl. 256, f. 55, 56), C. B. d4d.—Testa albida, sub-
opaca, superficie rugulis incrementi confertissimis striata; sutura
valde impress; anfractu ultimo depresso, magno, ad peripheriam
compresso. Ods. The specimens of this peculiar form, brought
by me from Japan, do not seem to differ in any respect from the
Neritina pusilla of C. B. Adams. The neritiniform aspect and
straight inner lip cause it at once to be separated from the other
species of Ze¢nostoma.

The “ paper sailor” is a testaceous receptacle formed by the
female Cephalopod for the deposition and care of her eggs. It is
secreted by the hinder pair of arms, which in the female are ex-
panded into broad membranes, and have been regarded as the
sails of a ship-like vessel; but they principally serve to envelope
the shell after its formation.

1. Arco (f. 1, 2), Lamsk.—Testa subcompressa, transversé
oblonga, lateribus planiusculis; rugis tenuibus, numerosis ; carin’
angusti, concava, tuberculis numerosis acutis; apertura subtri-
gona, angustd ; marginibus prope axem profundeé arcuatis, incras-
satis, in angulis plus minusve auriculatis. Os. This is the most
compressed species, the sides gradually converging to a narrow
keel, with very sharp tubercles. From the large square-mouthed
shell with the angles of the mouth produced into auricles, to the
transversely elongated and more finely ribbed varieties, with
scarcely any angle, the gradations are too minute to admit of
specific distinction.
2. Grunert (f. 9), Dunker.—Testa preecedenti similis, sed
parva, trausversé valde elongata; carind convexé, latiusculd, mi-
nuté verrucosi. Obs. Much more elongated than 4. argo ; wider
at that part of the aperture which is farthest from the spire.
The keel tubercles become more and more obtuse, till at the
outer edge they almost disappear.

: rede Lee iy : 2 : aie
in tuberculis divisis ; carind lata, tuberculis magnis subdistantibus;
apertura lata, auriculis productis, lateribus convexis. Os. Much
more convex and rounded, with the radiating ribs broken up into
small tubercles.
4. gonpota (f. 4), Dildéwyn.—Testa semiorbicularis, valde
convexa, pallidé fusca; rugis validis, distantibus, alternatim bre-
vioribus; carind latissima, distanter tuberculati; apertura laté
hiante, auriculis exterius productis. 04s. This is the widest shell
of the genus, the aperture widely gaping, and the keel very
broad, and the auricles produced and twisted outwardly.
5. urans (f. 5, 6), Déildwyn.—Testa convexa, subelongata,
fulva; rugis leviter elevatis, alternatim brevioribus; carina lata
obtusé et distanter tuberculata ; apertura lata, lateribus convexis,
auriculis rotundatis minimé productis. Ods. As compared with
the preceding, the ribs are not so pronounced, the tubercles not
so large and more obtuse, the mouth is narrower, and the
auricles not produced nor twisted outwards in this species.
6. Owent (f. 7, 8), Ad. and Reeve.—Testa semiorbicularis,
subcompressa, fulva; rugis validis, alternatim brevioribus ; ca-
rina lata, validé tuberculata ; aperturd oblong’, prope spiram an-
gustatd, lateribus compressis, auriculis vix productis. Os. The
ribs are more distinctly pronounced, and the sides of the shell,
particularly near the axis, much more compressed than in A. /zans.
MONOGRAPH OF THE GENUS
POMATIAS, Studer.
Pratt CCLIX.
Gen. Char. Molluscum terrestre, gasteropodum.
Testa turrita, pyramidalis, concentricé liris elevatis striata ; an-
fractibus numerosis, duobus apicalibus papillaribus levibus ; aper-
turd rotundato-subtrigona ; margine intus continuo, extus reflexo,
ad columellam angulato.
Operculo corneo, paucispirali, bilaminato.
Obs. These shells are turreted, pyramidal, striated, with the two
apicial whorls papillary and smooth. The aperture is slightly
trigonal, the inner edge continuous, the outer edge flattened out-
wards and angulated at the base of the columella. Operculum
horny, with few whorls, composed of two layers concamerated
within. The differences between the species consist chiefly in the
character of the striation.
SPECIES,
1. aurirus (f. 1, 2), Zeigd.—T. tenuis, subventricosa, pallidé
fulva; striis crebris, numerosis, alteris rarioribus crescentibus; labro
expanso, posticé acuminato, ad columellam in auriculam dilatato.
Obs. The largest of the genus; having the body covered with nearly
equal strie, with a few sharp and prominent at intervals. The
peritreme is expanded into a decided auricle at the base of the
columella, and pointed at its junction with the upper whorl.
2. ressELiatus (f. 15, 16).—T. P. aurito similis sed brevior ;
striis crassiusculis, eequalibus, ad suturam paululum exstantibus ;

distant spots near the suture, and another of longitudinal spots on
the middle of the body-whorl.
3. strioLatus (f. 5, 6), Porro.—T. ventricosa, pallida, fasctis
fuscis interruptis tribus ; stris crebris, numerosis, alteris rarioribus
magis elevatis ; labro angusto, tenui. Ods. More like P. tessed-
Jatus than any other, but the lip is thin and very little expanded ;
in striation it resembles P. awritus.
4. Puinrppranus (f. 21, 22), Gredler.—tT. P. tessellato similis
sed gracilior ; labro duplicato. Ods. In the striation and general
appearance this resembles the last, but is a much narrower shell,
with the inner edge of the aperture forming a ring raised above
the flattened outer portion. The middle row of spots not so
linear.
5. ScALArinus (f. 17, 18), /dda.—T. P. Phitippiano similis, sed
labro simplici angusto; macularum seriebus duabus, et fascia
basali. Ods. The lip is duplicated and very little expanded.
There is a band of brown colour near the base of the last whorl,
besides the two rows of spots above.
6. patutus (f. 11, 12), Drap.—tT. elongata, polita, fusco-
plumbea ; striis tenuissimis, crebris, versus anfractum ultimum sub-
evanidis; apertura subrotunda, patuld, labro duplicato. Oés.
Towards the lower whorls the very fine striz become faint and
almost disappear; the body of the whorl appearing polished and
shining.
7. Tersatines (f. 13, 14), Zeigd.—T. quam P. patulus bre-
vior, fasciatim maculata. Ods. Shorter than P. patulus, and
having three bands of spots.
8. osscurus (f. 3, 4), Drap.—T. subcylindrica, fusco-plum-
bea, fusco-rubescente triseriatim maculata ; striis tenuibus, crebris ;
labro paululum expanso, vix angulato. Ods. A rather pupeform
species, with two rows of spots and a band near the base of the
last whorl.
9. macutatus (f.7, 8), Drap.—T. quam P. obscwrus magis
angusta, labro haud tantum expanso, Ods, This species—or it
may be only variety—is narrower, with less expanded lip than
P. obscurus. P. apprimus is a variety of this.
10. cryerascens (f. 9, 10).—T. P. odseuro similis, sed imma-
culata; striis crassioribus. Ods. The strive in the upper whorls
are thicker, and the shell is more pyramidal. It is uniform in
colour.
11. Himarays (f. 19, 20), Benson.—T. pallida; anfractibus

rotundis ; sutura profunda; striis crebris crassis, super anfractum
ultimum alternatim brevioribus ; apertura subrotunda ; labro re-
trorsum reflexo, duplicato, angusto. Ods. This little whitish
shell has the whorls separated by a deep suture, a roundish mouth
with the peritreme reflected backwards, and the strie, which are
thick and regular on the earlier whorls, are on the last alternately
shortened.

(Reeve.)
12. reticuLata, Reeve, is our f. 94 (pallida, var.). It is
the true /. reticulata, as stated by Mr. Reeve in his monograph.
Our figure 47, 48, to which the name was inadvertently attached,
is certainly a different shell. See 12*.
12*, Regvu, Sowd., as reticulata, f. 48, 49, is a broad shell
with very short spine and conical shape. It is somewhat dif-
ferently marked from Sp. 12, and quite distinct.
34, MamILLa, Gray.—The first figures in Mr. Reeve’s mono-
graph and my father’s were taken from the shell in a very young
state. Very large specimens have since been procured.
35. PaPILtosa, Swains.—M. Kiener mixes this with /. /usi-
formis, aud names the two species together 7. Sowerbyi. Mr.
Reeve changes the name to “papillaris,”’ as conveying a more
correct meaning. I think it best to retain the original name, as
being in general use.
42. Inpica, Sows.—My father objected to Linneus’s name
Lapponica, as implying a false locality. Mr. Reeve remarks that
the name is only a corruption of “ Lapphorn,” or Dog’s-ear shell,
used for this species by the Dutch. Mr. R. agrees with my
father as to the propriety of abandoning the old name, but in-
stead of accepting his proposed substitute, gives a third name,
VOL, III. 2 M

“interpunctata.’ If the original name is dropped, the first sub-
stitute must be adopted ; but I think retaining even an ill-con-
structed name preferable to multiplying synonyms, and should
therefore say of the name Lapponica, in general use, s¢et.
46. potyzonatts, Lamk.—Should be virescens, Gmed., by
priority.
59. apyssicota (f. 124), Ad. and Rve.— Testa pyriformis,
tenuis ; spird brevi, subturrita, apice acuta; anfractibus superné
depresso-canaliculatis, liris numerosis acutis longitudinalibus et
transversis undique creberrimé subprofundeé cancellatis ; liris su-
perné mucronatis ; columellé quadriplicata ; apertura subangusta,
labro tenui, fulvescente-cinerea, fasciis rufo-fuscis angustis tribus
vel quatuor cingulata.” Ols. The cancellated surface of this
Voluta connects it with those Hocene fossils, such as V. dima,
elevata, crenulata, etc., which Swainson has generalized under the
name Volutilithes. One specimen dredged from a bank of dead
shells and rounded ironstones in 132 fathoms, Cape of Good
Hope.
60. currata (f. 122), Rue. Conch. Icon. pl. xxii. f. 56.—Ob-
longa, subpyriformis, solida, pallida, maculata, basi paululum re-
curva ; spira acuminata, elongaté; anfractibus plicatis, plicis sub-
evanidis ; apertura breviuscula; labro incrassato, intus obsoleté
denticulato ; columell& obscuré plicaté. Obs. This little shell
approaches the J/éra in form.
61. conumpEtta (f. 123), Sows.—Parva, oblonga, levigata,
pallida, maculis rufis picta; spiré acuminata; apertura elongata;
labro medio incurvo; columella obscurissime plicaté. Ods.
Having the form of Columbella nitida, and showing rather faint
plicee on the columella.
62. pEttctosa (f. 131), Montrouzier.—Resembles an inflated
specimen of /”, nucleus, with similar markings, but no ribs except
on the whorls near the apex.
63. casstputa (f. 130), Reeve.—Resembling /. nucleus, but
with the ribs more distant and slightly angulated on the upper
part of the whorls.
64. Dusuayustt (f. 134), Reeve.—A now well-known species,
resembling /. aulica, but straight-sided, with the teeth less ob-
lique and more thickened and flattened.
65. Sopuia (f. 132), Gray.—The “ four rows of distant chest-
nut-red spots” constitute the chief difference between this and
V. Norrisit.
VOLUTA. 271
66. Manrta-Emva (f. 133), Gray.—Described from a single
shell sent to Dr. Gray by Mr. Cuming for description, and now
deposited in the British Museum. It resembles V. swinodosa in
general form and colouring, but has a thick papillary spire, like
that of VY. seapha.
67. Rossryrana (f. 135), Bernardi.i—This magnificent species
resembles /’. imperiatis, but it has not the coronal spines pro-
duced, its sides are not so straight, the outer lip is expanded.
68. Exopranpa (f. 136), Sowd.—A fine shell of a rather coni-
cal form, with an angle near the top of the outer whorl. It is
finely reticulated, with two bands. ‘The spire is mamillated.
The aperture is rather narrow, and of a rich orange colour. Port
Lincoln, S. Australia.
69. rmynexa (f. 137), Reeve—Differs from V. rutila in being
more angular, having tubercles on the angle; the colouring is
similar in pattern, but paler.
73. Loroist (f. 1388), Valenciennes, Journ. de Conch.—De-
scribed from a worn specimen in the French Museum. It is
of a rounded oval form, of a pinkish colour with brown zebra-like
stripes. The plice on the columella are almost obsolete.
71. praurexta (f. 125), Reeve (Amoria Turneri Cumingii,
Gray).—Resembling /. reticulata, Reeve; of more solid texture,
much finer reticulations, with two rows of distant dark-brown
markings on the body-whorl. The teeth are fewer and less ob-
lique.
72. Turnert (f. 129), Gray.—Resembling /. pallida, Gray,
but the longitudinal lines, which appear in some specimens of the
latter near the apex, ornament the whole body-whorl in the former ;
besides which are two rows of distant cloudy large spots on the
last whorl. I believe it to be distinct, at least sufficiently so for
conventional purposes.
73. Aneastt (f. 29), Sow.—I propose to distinguish by this
name the shell which has been usually regarded as the Tasmanian
variety of /. undulata. The figure 29 hardly represents the dif-
ference sufficiently, being from a less developed specimen. But
the angular form and close angular markings of one, as compared
with the graceful elongation and less suddenly curved lines of the
other, are constant in all stages of development, nor haye I seen
any intermediate degrees which would cause embarrassment. The
diiferences have been pointed out in a note from Mr. G. F. Angas,
who has collected both species. The note concludes with the
272 MELO.
following observations :—“ Mr. Reeve has figured the Port Lin-
coln one (as if from Tasmania) as 7. undulata, Lam., which
shell agrees best with the description. If you consider them suf-
ficiently distinct, pray nae and describe the Tasmanian and Bass’s
Straits one as new. I have very rarely met with the Tasmanian
shell as far up the east coast of Australia as Port Stephens. The
Port Lincoln variety appears strictly confined to the S. Australian
shores westward of Cape Northumberland, and ranges to the
islands of the great Australian Bight, its metropolis being Port
Lincoln.”
74. Exxiorr (f. 126, 127), Sowd.—Fusiformis, subangulata,
solida; spira pallidé fulva, lineis fascis seu rubris fluctuatis longi-
tudinaliter pict4, breviusculd, apice subirregulari papillari; an-
fractibus paululum inflatis, suturis albis tumidis ; apertura pos-
ticé subangulata, anticé contracté; labro paululum incrassato, vix
dilatato ; columellé anticé incrassati; plicis quatuor, obliquis.
Ods. Intermediate in character between Dr. Gray’s V. Turneri
and the elongate form of V. undulata. It is decidedly more
angular than the former, from which it is more particularly dis-
tinguished by the form of the spire. In Zurneri and pallida, as
well as in Reeve’s reticulata and pretexta, the spire is regular and
conical, whereas in V. Hllioti the second or third whorl is always
a little swelled and generally obliquely placed. This places it
with 7. undulata in Dr. Gray’s division of the group, as having
the “apex large, subpapillary.” In fact, its apex is much more
like that of V7. undulata than that of any other of the series.
The lip is less thickened than in /. wndulata, more so than in 7,
Turneri, pallida, ete. See my pamphlet and plate accompanying
this.—Votura Evuiori, xame, figures, and description distributed

10. umprnicatus (f. 33). Mr. Reeve considers this to be /.
ducalis of Lamarck, but the description in the Ann. S. Vert.
does not identify it. The chief characteristic of VY. ducalis is the
shortness of the spines and the invariable protuberance of the spire
beyond them; while in I. wméilicatus the spines are, except in a
young state, long, and the shoulder on which they rest is high
above the apex, leaving it in a hole or wmbilicws. The reticulated
markings are a matter of minor importance. The mature specimen,
f. 32, completes the representation with f. 18, 29, 30.
11. reetus (f. 31), Schreb. et Wagn.—Mr. Reeve has com-
pared this with Cymbiwn Aithiopicum, showing the differences.
There are specimens of MZ. diadema figured in the ‘ Iconica’
which more nearly resemble it. It is, however, a more rounded
shell, with a less oblique columella.

SECOND* MONOGRAPH OF THE GENUS
HELICINA,
INCLUDING THE GENERA TROCHATELLA, LUCIDELLA, HELICINA,
SCHIASCHEILA AND ALCADIA, OF AUTHORS.
Char. Gen. Molluscum terrestre. Testa spiralis, helicoidea,
labio interno ab anfractu ultimo haud distincto, plerumque circa
columellam calloso. Operculum testaceo-corneum, subquadratum,
non spirale.—Land-mollusk. Shell spiral, helicoid, inner lip not
distinct from last whorl, generally callous round the columella.
Operculum horny-testaceous, rather square, non-spiral.
My objection to the smaller genera adopted by some authors
chiefly arises from the impossibility of defining them. Taking
the genus Helicina as above described, its limits are perfectly
discernible; no one having a complete specimen in hand, can
doubt whether it be a Helicina or not. The definition includes
all that belongs to it, and excludes all that is foreign to it. This
cannot be said of any description that has been or that can be
given to Trochatella, Alcadia, ete. The notch between the colu-
mella and base of the outer lip, upon which the latter genus is
founded, is a thing of infinitesimal degrees, from a little depres-
sion in front of a thick tooth to a spirally incised slit, and thence
to a scarcely perceptible sinus in the thin peritreme of some
smaller species. (See Plates I. and II.) The chief character of
Trochatella is the absence of callus at the base of the lower
whorl, but if that were made the basis of division it would in-
* The number of species contained in the former monograph is so small com-
pared with those which are now known, that it has been thought better to
make the present monograph complete, even at the inconvenience of repeating
the figures of the former seventy species. The advantage of this will be to
preserve to the eye the entire series in the order of their affinities. Subseri-
bers will not lose by this, as we have compensated by giving them a consider-
able number of extra figures in the present double part.

clude many incongruous shells, and exclude others which notwith-
standing are enumerated in the lists hitherto published.
I have endeavoured to group together, without defining, those
species most nearly resembling each other, and if the groups so
formed do not correspond with the generic divisions referred to
above, it is because particular characters are not always found in,
or confined to, shells of the same general aspect. Generic
names require generic definitions, and the genera into which the
Helicine have been divided cannot be defined. Yet a system of
general grouping without such definitions may be usefully em-
ployed.
This being a second monograph, I have not here given full
descriptions of the species, but have been content with mention-
ing in a word or two about each some peculiarity of the shell as
compared with others of the same group,—trusting in this way,
by the help of the figures, to give a better idea of the species
than would be done by more elaborate descriptions in which
many characters would have to be repeated.

The three known species composing this little section differ
from other Helicine in the form of the operculum, which is
beaked at each extremity, in the existence of a sinus in the peri-
treme at each end to receive the beaks, and in the columella being
partly separated from the body whorl. These characters are in-
teresting, although scarcely definable and exclusive enough to be
considered of generic importance.

projections. ‘These, together with the sinuous depression of the
upper part of the lip, contract the aperture im a peculiar manner,
56. Aureota, Fer., (f. 94, 479.)—Striata, subrotunda.—Stri-
ated, roundish.

Sect. V. Trochiformis, solida, spiraliter lirata—Genus 'TRocHA-
TELLA, Szains., inclusa.
I have searched in vain for any definition of this section suffi-
ciently exclusive and inclusive to constitute it a logical or con-
venient genus. Pfeiffer and A. and H. Adams appear to rely
upon the absence of the basal callus or circular extension and
thickness of the inner lip, although those authors enumerate
among T'rochatel/z some species showing that character slightly,
and exclude great numbers of Helicine which have no more
callus than their most typical Zrochatellz. We wust be content,
therefore, with uniting in a scarcely defined section the following
pyramidal, spirally grooved species :—
60. stnuosa, Pfr., (f. 96.)—Labro sinuoso, labio interno cal-
lum posticum emittente.—Outer lip sinuous, inner lip with a
posterior callus.

MONOGRAPH OF THE GENUS
CARINARIA, Lamarck.
Testa vitrea, pileiformis, concentricé rugata, dorso carinato,
apice subplanulatim spirali.
Shell glassy, cap-shaped, concentrically wrinkled, with a dorsal
keel and a nearly flat spiral apex.
The Carinaria is an oblong mollusk, provided with a broad fin,
by means of which it moves very rapidly through the ocean. ‘The
beautiful glassy shell which it secretes forms a protection to the
breathing apparatus.
SPECIES.
1. C. virrma, (f. 4).—T. elevati, subtrigond, lateribus recti-
usculis, apice parvo, uncinato.—Distinguished by its elevated,
conical form, nearly straight sides, and small apex.
2. C. cristata (f. 2, 3), ZLinu.—T. depressd, oblonga, dorso
arcuato, latere postico declivi, apice lato, deflexo.—Of an oblong,
depressed form, with the back arched, the posterior side sloping,
and the apex broad and curved downwards.
3. C. Aruantiea (f. 1), Ad. § Rve.—T. subelevata, curta,
dorso validé arcuato, carina lati, apicé arcnatim depresso, corneo.
—This pretty little species is shorter, with the back more curved
and elevated than C. cristata. It has a horny nucleus.

MONOGRAPH OF THE GENUS
DONAX, Linneus.
Chur. Gen. Testa eequivalvis, inequilateralis, subtrigona, bi-
musculosa, posticé plus minusve truncata ; pallii impressione laté
amentata ; ligamento externo; dentibus cardinalibus in valva dex-
tra duobus, in valva sinistra uno; dentibus lateralibus duobus,
approximatis vel uno remoto.
A large sinus in the impression of the mantle, and the absence
of a cartilaginous pit, will be sufficient to distinguish the shells of
this genus from the few others with which they might otherwise
possibly be confounded.
SPECIES.
1. scortum (f. 1, 2,3), ZLinnw.—Testd tumida, subsequilaterali,
striis radiatis et liris concentricis decussatd, extus alba seu pallide
fulva, violaceo concentricé fasciata, intus violaced, anticé subacu-
minata, laminis laqueatis subdistantibus fimbriata, posticé acute
arcuatim angulata, ad angulum spiniferd, area postangulari con-
cava, acuminata, decussata.—Specimens differ in the degree of
development of the spines and fringes ; and we have in our hands
.a specimen from Mr. Taylor’s collection which is white, and has
the posterior angle produced remarkably.
2. cartnatus (f. 4, 5), Han/.—Testd tumida, lata, polita, cas-
taneo-violaced, radiatim impresso-striata, striis antice evanidis,
umbonibus elevatis, angulo postico subcarinato, area postangulari
arcuatim declivi, concava, striata, infra producta, acuminata, latere

There is some difficulty in identifying this shell from the original
description, but I have not much doubt about it ; some specimens
of the last species come very near to it, particularly about the
umbones, which are very peculiarly coloured, but the shells of
this species are narrower. ‘Tne swelled and elevated character of
the back area is easily observable. ‘The gradation of specimens,
however, prevents our separating the varieties named D. cu/ter.

postangulari convexo, medio obscuré angulato, prope umbones
complanato.—Although the variety of this well-known species,
named PD. epidermia, is generally rather longer and less elevated
in form than the dark purple one, there can be no doubt that it
is identical.
38. Trcaonrcus (f. 96), Zan/.—Testi trigono-elevaté, tenui-

anticé attenuata, subacuminata, latere antico-dorsali incurvo, um-

acuminately produced umbones, and the incurved character of the
anterior dorsal slope.

shell, distinguished by undulating, granulated rugosities on the
area behind the angle. D. granosa is most probably a variety of
this.
40. comprzssus (f. 97), Lamk.—Testa D. cuneate simillima,
sed magis elevaté, umbonibus productis, margine antico-dorsali
subincurvo.—The greater depth from apex to ventral margin and
the concave outline of the antero-dorsal slope distinguish this
from D. cuneuta.
41. conummtuts (f. 113, 114, 115).—Testa quam D. cuneata
magis ovali, angulo postico magis rotundato, rugis postangularibus
tenuissimis.—More oval than D. ewneata, with the posterior side
more rounded and much more finely ridge-striated.

has a very obtuse angle in the usual part, and a second angle in
the middle of the area; the area is granosely striated.

umbonibus perelevatis, margine ventrali antice subcontracto,
posticé convexo.—This curious species is distinguished by the
sculpture of the posterior area and the short straightness of the
posterior side, and other peculiarities of form. I see no distinction
in this from D. Dysont.
44, naprans (f. 91, 92, 93, 94, 95), Lams:.—Testa ovato-sub-

angulum subcontracto, medio convexo, intus levigato.—This
small, obtuse species is very variable in colouring and even in
form. ‘The ridges are irregular, strong at the back, and more or
less obliterated in the middle. Fig. 95 probably represents D.
villatus, Lamk.
45. Faspa (f. 108, 109), Chemu.—Quam D. radians magis
elongata.—Lamarck quotes the figures in Chemnitz and the Hn-
cyclopeedia for his D. radians. Had this been correct, Chemnitz’s
name must have been adopted by the law of priority. But the
ficures thus referred to show a much more elongated shell, which
agrees with the shells which we now figure. It is doubtful, how-
ever, whether the distinction can be well maintained.
46. appreviatus (f. 106, 107), Lam&s.—Testa suborbiculari,

for the present locked up in the late Mr. Cuming’s cabinet, I
cannot decide whether this is not a variety of D. nuculoides.
The question would depend upon the character of the described
striation.
51. serra (f. 87), Chemn.—Test& crassi, ovato-subtrigona,

recto, concavo, valvé sinistra peculiariter elevati et compressi.—
The variation in form is considerable among the specimens of this
species, some being flatter, broader, and more truncated than
others. ‘There is a peculiarity in this and the following species
which has not been noticed. The mght valve overlaps the other
at the posterior part of the ventral margin, while the left valve
is peculiarly flattened and elevated above the other at the dorsal
line near the hinge. Several true British specimens exist: one
well authenticated, in Mr. Jeffreys’ collection.
53. vetiicatus (f. 61, 62, 63), Reeve.—Testa polita, tumida,

posterior angle, whence this shell derives its name, is a variation
common to many species. ‘I'he curious inequality of the valves

in this.

prope umbones nonnunquam liris concentricis rugata, margine ven-
trali subeequaliter convexo, margine dorsali antico declivi, subexca-
vato.—This shell is stouter and more regularly oval than its nearest
allies. In most of the specimens can be traced a decussated
sculpture in parts from the posterior angle to the middle. In
D, semistriata, Poli, this character is strongly marked and covers
two-thirds of the shell. In the young state the postangular area
sno strong ridges, which disappears partially or wholly when
adult.
55. In consequence of an alteration in the nomenclature and
synonymy of wttatus (Anatinum), truneulus, etc., this number is
omitted. Mr. Jeffreys having thoroughly investigated these
species, | have adopted his views.
56. Cumrnen (f. 64, 65), Dunker.—Testa oblonga, compla-

fulvo triradiata, anticé producti, prope marginem levigata,
posticé et medio rugis concentricis prope marginem rectiusculis

shell exhibits a sculpture at the back of the angle and along a
portion of the posterior and middle of the surface similar to that
in the young of the Mediterranean variety of D. anatina, but it
seems too long and straight for that species.
58. porrrus (f. 84, 85), Da Costa.—Testa elongata, levigata,
compressa, luted, spadiceo variegata, post medium fascia alba
radiata, anticé elongat&, marginibus dorsali et ventrali paulo con-

The young shell figured by Reeve under the name D. variegata

There is no danger of confounding this semifransparent little
narrow species with any other.

Mr. Taylor’s collection and our own, were at first taken for the
young of some large flat species, such as cuncata, but on exami-
nation they were found to be not at all rugose posteriorly but
only radiately striated.

rotundis apertis, intts penetrantibus, inter varices instructis ;
apertura ovali, subcontracta, subintegra, canali clauso ; operculo
corneo, nonspirali, nucleo subterminal.
Between each varix on the upper part of each whorl is a round
tube, the hollow of which penetrates into the interior of the shell.

curvis, cum varicibus junctis, varices arcuatos duplicatos tubiferos
formantibus.—Hach tube is bent back into the preceding varix,
so as to form with it a double arched varix ending in a tube.
Note.—The shell named Typhis Angassii, of Crosse, is not a
. . S . J . Z . 4
Typhis, having no tube penetrating to the mterior.

infra subacuminata, integra ; columella obliqué truncata, anfrac-
tibus paucis, ultimo magno; epidermide corned, super carinas
frequenter ciliata ; operculo corneo, non spirali, nucleo terminali.
A genus of carinated spiral shells, belonging to the Buccinwm
family, but differing from Buceinwm in the want of a distinct
canal. The thin epidermis with which the shell is covered is in
many species ciliated at the keels. “Operculum non-spiral, with a
terminal nucleus.
SPECIES.

rumque pallidé rosea, subtrigond, ad terminum inferiorem acumi-
nata, labro ad costarum terminos angulato; epidermide super
costas duplicatim ciliat’i.—Specimens from different localities
differ much in relative proportions, some being much more acu-
minate than others. Fig. 1 may be taken to represent the typical
British form; fig. 3 is drawn from a eseines in the British
Museum, from Behring’ s Straits, and fig. 2 is the acuminate form
which has been named 7. Atlantica.
2. costeLLata, Couth., (f. 6)—Quam 7. dorealis tenuior,
costis tenuioribus, inferioribus magis numerosis.—Thinner than
T. borealis, with thinner ribs ; instead of two rather stout ones
beneath the three upper ones, there are four or five very small.

validis ad angulos, und intermedia et und inferiori cincto; aper-
turd angulata, columella obliqué truncaté acuminata, labro externo
margine inferiori rectiusculo, vix acclivii—This conical shell is
figured from drawings, kindly sent to me by M. Morch, of speci-
mens taken in Greenland. Since figuring it I have examined a
shell in the collection of A. Adams, Esq., which, although thicker
in substance, I believe to belong to the same rare species.

Museum, from which the figure in Sowerby’s ‘ Genera of Shells’
was taken.
APPENDIX TO MONOGRAPH OF THE GENUS
CONUS.
(Sequel to p. 47, Pt. 18.)
404. compressus, Sowd., (f. 602, 603).—C. angustus, subcy-
lindraceus, spiraliter tenuissimé striatus, infra sulcatus, pallidé
rubescens, maculis castaneis irregulariter pictus, spira gradata,
castaneo maculati, anfractibus compressis.—This shell has some
resemblance to C. anemone, but it is more solid in texture and
the whorls are much more compressed, 7.e. a greater number
contained within a given circumference.
405. RosEo-T1NctTUus, Sowd., (f. 604).—C. subpyriformis, pallidé
roseus, ad spiram castaneo maculatus, supra usque ad medium
tubro maculatus et nebulosus infra medium albido unifasciatus,
infra fasciam rubro flammulatus, superné prope angulum spiraliter
striatus, versus basim subduplicatim sulcatus.—Slightly pyriform,
narrow towards the base, beautifully tinged with rose and clouded
with darker tints which culminate into reddish-brown spots near
the centre.
406. anactyptus, Crosse, (f. 605, 606).—A pretty little rose-
tinted shell, described in the ‘ Journal de Conchyliologie,’ nearly
resembling C. verrucosus in form and sculpture.
407. Moussont, Crosse, (f. 607, 608).—C. solidus, flavidus,
maculis aurantiis magnis pictus, medio subinflatus, infra con-
tractus, granulatus, anfractibus coronatis rotundato-angulatis.—
A solid, yellowish shell, with large patches of orange. It has a
coronated and roundly angulated spine.
408. straturatus, Sowb., (f. 609, 610).—C. oblongus, sub-
pyriformis, supra subinflatus, infra angustatus subtortuus, albus

turd lata ; columella distinctéi.—Resembling C. col/isus, Rve., but
distinguished by the style of marking, the vertical flame-marks
being cut across by the white-edged grooves.
409. Linnarpi, Bern. et Crosse, (f. 611-614).—A species
belonging to the same group as C. Bernardi, etc., but differing
in the form of the spire, the whorls of which are carinated. The
four beautiful specimens figured are in the collection of Mr. G. F.
Angas.
410. suscarinatus, Sowd., (f. 615).—C. turbinatus, sublevi-
gatus, infra rudé sulcatus, albus, pallidissimé purpureo tinctus, flam-
mulis fuscis irregulariter angulatis longitudinalibus, medio inter-
ruptis pictus ; lateribus rectis ; angulo subcarinato ; spird prope
angulum convexd, apice acuminato. Variat fasciis duabus latis,
lineis interruptis cinctis ornata.—A more solid and much broader
shell than C. voluminalis, which it somewhat resembles.
411. excavatus, Sowd., (f. 616).—C. C. coffee simili sed macu-
lis magis regularibus, anfractibus supra angulum excavatis, cancel-
latis, infra angulum rotundatis.—This shell has a more compact,
neat, and regular appearance in texture, colour, and markings
than C. coffea, besides which it has a round excavation on the top
of the whorls, and a rounded shoulder beneath the angle.
412. Macarm, Bernardi, (f. 617).—A shell of remarkable
form and colouring, described and figured in the Journ. de Conch.
413. nicrescens, Sowd., (f. 618).—This shell is more pyri-
form than others of the same group, its coronation consists of
few large and sharp-edged nodules, the colouring is deep and
has a peculiar half-transparent, tortoiseshell richness, the heart-
shaped white spaces are small and comparatively distant.
414, proximus, Sowd., (f. 619).—This exquisite shell, de-
scribed in the Proceedings of the Zodlogical Society, has a general
resemblance to C. Molluccanus, but its characters, which can be
seen in the figure, distinguish it perfectly.
415. Macut, Crosse, (f.621).—A thin shell, resembling C. Ja-
maicensis, but of a more inflated, although still cylindrical form.
416. caine, Bernard, (f. 623).—A much stouter shell, and
of finer texture than C. emaciatus. The columellar fold is very
strong.
417. conpENsus, Sowd., (f. 622).—C. cylindraceus, crassus,
roseus, fusco rubescente tenuiter reticulatus, spiraliter striatus,
infra contractus, spirA conicd, obtusi.—A connecting link be-
CONUS. 327
tween the groups to which C. auratus and C. textile respectively
belong.
418. Cuznut, Bern., (f. 624).—Resembling C. dineatus, but
smoother and more straight-sided.
419. puanaxis, Desh., (f. 625).—This appears to have been
described in the Book on the Isl. Bourbon, from a very young
specimen. It is remarkable for the flatness of its spire.
420. sprroeiossus, Desh., (f. 626).—This, like the preceding,
seems to have been figured and described from a specimen too
immature to be very characteristic.
421. Conpexti, Bern., (f. 627)—A rather short, thick shell,
of angular form, with patches and zigzag markings of chestnut
colour. From the figure it would appear that there are several
distant, strong spiral ridges near the base.
422. Crossnanus, Bern., (f. 628, 629).—In the typical variety
of this species the white heart-shaped spots have a tendency to be
iregularly elongated vertically—There is a slight shoulder near the
angle of the whorls, and the crowning tubercles are small, obtuse,
and have a peculiarly pinched-up appearance when not obsolete.
423. miseR, Boivin, (f. 630).—This species, from Cape Verd,
has been frequently named in collections, by error, C. sizdon, Rve.
The latter is, however, a much more cylindrical shell.
424. Vitunprnt, Bern., (f. 629*).—Belonging to the same
group as C. undatus, C. emarginatus, etc., but differently marked,
it is contracted at the sides and strongly grooved near the base.
425. Dapune, Boivin, (f. 630*).—Judging from the figure,
this species must in some degree reseinble C C. conspersus or C.
Broderipii.
426. Cucritm, Bern., (f. 631%*).—Sculptured with lines of
granulation, otherwise resembling C. capitaneus.
427. Capririt, Bern., (f. 632).—Distinguished by spiral
punctured striz, the whorls rounded at the margin and crowned
with rather indistinct rounded nodules.
428. muLticateNnatus, Sowd., (f. 638, 634).—Conus brevis,
solidus, acutangulatus, levis, albus, prope angulum distanter
nigro maculatus, fasciis latis duabus interruptis et lined textili
interrupt&é medianai cinctus, super fascias lineis fuscis maculis
rotundis albis catenatis ornatus; lateribus rectiusculis; spird
brevi, distanter et late mnculaiaes anfractibus supra concavis.—
328 CONUS.
The spire is rather flat, and the tops of the whorls hollow. The
peculiarity of the colouring consists in the chain-like bands of
black spots and white intervals appearing across the large chest-
nut patches.
429. noputosus, Sowd., (f. 635).—C. turbinatus, acutangu-
latus, flavidus, lineis angulatis, rubris reticulatus, intts pallidé
roseus, infra acuminatus, striatus, labro superné emarginato, spira
elevata lateraliter convexa, anfractibus gradatis superioribus nodu-
liferis. —Differing from C. acuminatus, ar only in general aspect,
but as a lighter and less solid shell, the lateral outline of the spire
being convex and the upper whorls coronated.
430. Tasmanta, Sowd., (f. 636).—C. elongato-cylindricus,
luteus, strigis irregularibus longitudinalibus rubescentibus pictus,
spiraliter leviter liratus, supra acutangulatus, apicé depresso, infra
angulum subinflatus, versus basim attenuatus.—Differing from C.
Magus chiefly in the narrow, attenuated form.
431. QuapRatomacuLatus, Sowd., (f. 637, 638).—C. acutan-
gulatus, solidus, levis, maculis quadratis seriatim pictus, in fasciis
duabus nebulosus, lateribus rectis, apice depresso acuto, apertura
angustata, margine maculato.—Somewhat resembling C. Keatii
in markings and form, but is a more solid and smaller shell,
narrower, and with straight sides and more depressed apex.
432. acutmarernatus, Sowd., (f. 640, 641).—C. acuminatus,
breviusculus, pallidus, distanter biseriatim maculatus, distanter
spiraliter sulcatus, apice acuminato, gradato, anfractibus acute
carinatis, labro eleganter sinuato.—In some respects resembling
C. voluminalis, but smaller and shorter, with the spire more ele-
vated and the whorls sharply carinate.
433. ctrcumstenatus, Crosse, (f. 620).—C. subcylindraceus,
oblongus, obtusé angulatus, lineis punctatis et granulatis cinctus,
nebulis aurantiis ad angulum et infra medium interruptis picta,
apice subrotundatim convexo.—Judging from the figure in the
French journal, this must be a very interesting species.
434, aNABATHRUM, Crosse, (f. 639).—C. acutangulatus, levis,
flavidus, infra acuminatus, ad angulum et infra medium albo in-
terruptim fasciatus, anfractuum angulo acuto; apice gradato, ele-
vato, acuminato.—Of the sharply angular, acuminate form which
characterizes the group to which C. wudatus, ete., belong.
435. TuRRICULATUS, Sowd., (f. 648, 644).—C. subfusiformis,
curtus, medio subinflatus, supra et jth attenuatus, acuminatus,
sp siraliter sulcatus, sulcis numerosis, puncturatis, interstitiis ro-
CONUS. 3829
tundis, spird elevatd, acutangulata, ad angulum anfractuum moni-
liferé, anfractibus supra angulum levigatis.—More fusiform ‘and
more finely sculptured than C. acutangulatus, the margin of all
the whorls coronated, in the latter respect differing from C. pre-
cellens, in which they are quite smooth.
436. ARCHETYPUS, Crosse, (f. 645, and as C. daucus, var. f. 330).
—There can be no doubt that the shell figured in plate 14, as
a variety of C. daucus, is identical in character with the one
figured in the French journal. The oblong-square markings and
the more rounded angle of the upper edge of the whorls sufficiently
distinguish both specimens from C. daucus.
437. corvicEra, Sowb., (as C. nobilis, pl. 21, f. 498).—C.
quam C. nobilis supra et infra medium magis inflatus, infra angu-
lum subrotundus, maculis cordiformibus albis approximatis, sub-
longitudinalibus, non linea rubra marginatis ; spire: anfractibus
magis planulatis, apice albo.—The two shells which, in all the
great collections and all the books, have been placed side by side
as varieties of C. xobilis, appear to me to be exceedingly distinct.
The four or five points of difference are quite constant, and I have
never seen a shell intermediate in respect to any one of them.—
The apex is always pink in C. nobilis, and white in C. cordigera.
The former has its heart-shaped white spots bordered with a
line of strong colour on the front side, the intervening spaces
are wide, and crossed by articulated lines, the outlines of the
shell are straight, and in each of these particulars C. cordigera
differs from it.
438. concinnus, Sowh.—C. subpyriformis, levis, infra sul-
catus, solidus, purpurascens, spiraliter lineis interruptis cincta,
anfractuum margine acuto distanter nigro-punctato.—A smoother
and neater shell than C. punctatus.
439. BornegEnsis, Sows., (f. 648).—C. subcylindrica, oblongo
infra attenuatus, sulcatus, supra subinflatu, levis, obscure fulvus,
rubro obscuré flammatus, apertura intis purpurea, margine ma-
culato.—The only specimen of this shell we have seen is in the
collection of T. L. Taylor, Esq.
440. Paztr, Bern., (f. 649).—C. crassus, turbinatus, obtusé
angulatus, albidus, fasciis quater latis castaneis cinctus, medio et
ad marginem superiorem maculis quadratis tessellatus.—At first
sight this would appear to be one of the numerous varieties of
C. venulatus, but the tessellated character caused by the white
lines cutting off and defining the square spots, is perhaps suffi-
cient to distinguish it.
330 CONUS.
441. comeLanatus, Sowd., (f. 650, 651, and as C. Victoria,
var. pl. 23, f. 576).—C. quam C. Vietorie magis inflatus, latior,
lineis reticulatis tenuioribus, apice magis complanatus.—The true
C. Victorie, which is a thick, rather narrow shell, with large
open, principally vertical pattern and much elevated spire, may
properly be kept distinct from the broader, flat-topped, more
inflated, more finely reticulated, and banded shells here named.
The variety fig. 650 is very peculiar in its chain-like reticulation,
but in other characters it bears the stamp of the new species.
442. Rottanpi, Bern., (f. 652).—C. subcylindricus, longi-
tudinaliter striatus, spiraliter distanter sulcatus, anfractibus su-
perné rotundis, suturd crenulaté.—Our figure is copied from
Bernardi’s work, in which the “ festooned” suture and the longi-
tudinal fine ribs are not visible. It must, however, be an inter-
esting shell.
443. consuL, Boivin, (pl. 21, f. 509).—When the varieties
now grouped under the name C. magus come to be properly
compared it may be found necessary to separate the elongated
variety with articulated lines. In that case, the name given by
Boivin will be applied to it.
444, Fravenrewpt, Crosse.—Of the two figures representing
this species in the ‘ Journal de Conchyliologie,’ one is that of a
zebra-striped variety of the solid, thick-shouldered shell which is
identified in my work as C. circe of Chemnitz. See pl. 21, f. 514,
and pl. 22, f.525. The other is that of a shorter shell than
C. magus, and wider at the base. It agrees well with some speci-
mens received from Borneo, which are now in Mr, Taylor’s col-
lection. This may be received as a species not difficult to dis-
tinguish.
445. ALABASTER, Jeeve, (f. 631).—Since the publication of
our monograph specimens have come to hand from the collection
of Mr. Taylor. It is a beautifully sculptured white shell.
446, Lizarpensts, Crosse—A straight-sided small cone, with
reddish flame-like markings in two rows.
447. srrtotatus, Reeve, (f. 827, 328).—United, by error, to
C. ustulatus, Reeve.
Species not identified or not adopted.
BarrueLemyt, Pedit, Journ. Conch. From the specimen sold
recently in the Robilliard sale, I had no hesitation in saying that
CONUS. 331
it was a remarkable variety of C. awrisiacus, having a broad belt
of orange on the upper part, and a white band below the centre
with dark spots. Mr. Crosse, however, kindly pointed out some
distinctions which make it necessary to see the shell originally
described before finally deciding.
