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.

59. rosEus, Lamk.—C. brevis, solidus, turbinatus, sulcatus,
9
roseus seu griseus, medio fascié pallidé cinctus; spird obtusd, no- dulis albis coronaté, interstitiis nigris (f. 94, 95).—Turbinated, grooved, pink or grey, with a light or white band in the centre ; nodules of the spire white, with dark spots between.

This and the four following are probably varieties of the same.
61. Barpapensis, Brug.—C. C. minimo similis, sed magis elon- gatus, lineis transversis sparsim punctatus (f. 57, 58).—Of a more oval and elongate form than C. minimus, generally more lightly coloured, with the encircling spots fewer.
62. mncaustus, Kien.—C. C. minimo similis, sed ad spiram magis angulatus, lateribus rectiusculis, striis transversis albo gri- seoque tessellatis (f. 79).—There is greater angularity of form in this species than in C. minimus, and a peculiar tessellated style of marking.
63. AristopHanes, Duclos.—C. C. minimo similis, sed lineis interruptis transversis majoribus (f. 81, 82).—The cross-lines of black and white spots are fewer and wider than in C. minimus.

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.

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.

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.

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).

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.

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.

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, downward stripes.

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.

22. TankeRvILu, Swains.—A. ovali-elongata, aurantio-flavida ;

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- qualibus; columella callosi, superné incrassaté, super anfractum 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.

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.

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.

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.

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-

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

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.

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

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,

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.— Elongated lanceolate, snow-white, shining, gaping at both ends (especially below anteriorly), convex or subventricose, retusely compressed below in the middle, with an indented ray in front ;

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 concentrice et elevate, mox acclinate et (certissimé in valvula sinistra ubi inferné prope plicam umbonalem planulatam demumque sublevigatam prorsus desunt) magis minusve oblique. Margo dorsalis uterque vix declivis. Area planulata, crenulato-margi- nata.—Hlongated, rather shorter and rounded-lanceolate in front,

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 attenuata, undique striata: striae concentrice, dense, argute. Margo dorsalis anticus convexiusculus, vix declivis; posticus 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 fiunt, longitudinaliter corrugata.

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, parva, valida, subanguste oblongo-rostrata, posticé attenuata, albida, liris concentricis tenuibus undique corrugata.

Area ampla, depressa, crenulato-marginata.—Of an elongated beaked-oblong shape, ra- 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. Front dorsal slope rather shght ; hinder dorsal slope slight, in- curved. Ventral margin arched behind, straighter im front, sub- retuse at its termination and very slightly so in the middle.

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, plano-convex ; hinder dorsal slope rather slight, incurved, rising 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 triangular cartilage-pit very numerous.—The epidermis is occa- sionally iridescent.

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.

Dor- sal slopes moderate ; front one convex; hinder one straightish or subretuse. Ventral margin arcuated in the front and middle, rising at both ends, straighter behind. Lunule small, narrow, subgranosely cross-barred: escutcheon large, concave, crowded with longitudinal costellar strize, whose intervals appear punctulate from the minute transverse sculpture. About a dozen teeth on either side of the minute cartilage-pit—Mr. Hinds had confused this rare little shell (of which Mr. Cuming, Mr. Metcalfe, and myself, each possess asingle individual) with his WV. crispa, which name has been retained for the delineated species. An incipient ridge almost renders the larger dorsal area a double one. I have seen no epidermis.

which is crossed by the numerous regularly disposed sublamellar concentric ribs that evenly traverse the entire surface except the dorsal areas, and a smooth nuclear region: their intervals, which are rather broader than the ribs, unsculptured, except where a few raised lines indistinctly and partially margin the broad shallow rudimentary anterior indented ray. Sides nearly equal: front extremity broadly and bluntly rounded; hinder side abruptly beaked, the tip very narrow, remarkably cocked-up, bluntly acu- minated, above the middle. Front dorsal slope rather slight, short, plano-convex; hinder dorsal slope decided, incurved. Ventral margin much arcuated in front, straighter and much rising behind, retuse before its posterior termination. Lunule well defined, cross-barred by riblets: escutcheon very large, ex- cavated, smooth at the circumference, costellated lengthways near the beaks. Hinge-margin very broad, teeth numerous, especially in front. Cartilage-pit extremely minute, triangular. Hpidermis unknown.

Margines dorsales vix declives. Are dorsales anguste, definitee, dentes utrinque permultii—Oblong convex or subventricose, devoid of umbonal ridge, pale-tawny, closely graven with obliquely concentric striz, which do not extend to the hinder triangle. Extvemity of the anterior side, which occupies nearly three-sevenths of the total length, unsymmetrically rounded. Posterior side rather tapering, bluntly obversely subcuneiform ; the extremity broad, convex, and above the middle, with a long shallow dorsal notch. Dorsal slopes very slight, nearly straight. Ventral margin archmg up in front, then convex or subarcuated, straighter behind: posterior edge oblique, somewhat convex, yet a little retuse in the middle. Dorsal areas narrow, but well de- fined. Cartilage-pit broadly triangular: teeth numerous on both sides.—Although long known and often described, I have never 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- barica, because the other two are deceptive ; for the shell is neither smooth nor transparent. I doubt whether Spengler ever really published his Illustrated Catalogue.

Margo dorsalis uterque vix declivis, anticé convexiusculus, posticé recti- usculus ; ventralis ad extremitatem posticam subito acclivis. Area lanceolata, acuté definita, subleevigata.—Hlongated-oblong, more or less ventricose, only compressed on the convex-surfaced posterior triangle, which (as well as, occasionally, the hinder umbonal region) is devoid of the distant concentric subimbricating sulci which else- where traverse the highly polished pale mud-yellow exterior. An- terior side rather short, filling about three-sevenths of the total length, unsymmetrically rounded. Posterior side gradually at- tenuated, not beaked, angulated and more prominent above, with a slight dorsal notch or sinus: posterior edge convex, oblique. Dorsal slopes trifling; front one convex, or plano-convex ; hinder 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.

Dentes utrinque permulti.—Most closely resembling ¢ened/a, but larger, rather less 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, sweeps almost uninterruptedly, without central retusion, to the 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- liarly small, and not all prominent. Dorsal areas inconspicuous. Inside bluish-white, subiridescent : cartilage-pit small, triangular : teeth very numerous on both sides, peculiarly narrow-based, and elevated.

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.

Area haud impressa, vix definita.— Elongated-oblong, fragile, merely convex, subequilateral, yet longer in front, gaping a both extremities, with a shallow in- dentation radiating from the acute beaks (which are reflected and by no means prominent) to both ends of the ventral margin, and obsoletely sinuating them, narrowly rounded in front, subtruncately 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, much arcuated in front, convexly rising behind. Escutcheon lanceolate, not sunken, nor sharply defined, merely indicated by a cessation of the convexity, its edges pouting: lunule wholly obsolete. Interior bluish-white: teeth very numerous.

Anterior side slightly the longer, almost symmetrically rounded : posterior side bluntly peaked, rounded- subtruncate at the extremity, which is subcentral, but projecting more above the middle. Front dorsal edge arcuated, and mode- rately sloping: hinder dorsal edge straightish, and not much sloping. Ventral margin subarcuated, but with a slight anterior retusion, and a still more trifling posterior one. Dorsal areas undefined; the hinder dorsal lips pouting.

The lunule, too, though indistinct, is wrinkled by sulci. ‘There is no vestige of an umbonal ridge, and the posterior compression is less marked. The anterior side is decidedly the longer, and blunter (less rounded) at its extremity: the hinder termination is less peaked and more truncated, the extreme projection is, for the most part, above the middle. ‘The epidermis, which ranges from yellowish-olive in the young to dusky-olive in the adult, is less polished. The front dorsal edge is straighter: the ventral margin rather less arched, and the retusions are still less apparent. The
cartilage-pit is broadly triangular ; the teeth numerous on either side.*

Anterior side occupying about four-sevenths of the total length ; its upper and lower slopes, the former of which is decided and subarcuated, the latter much rising, almost symmetrical; its tip (in the adult) narrower and less rounded than the broad extremity of the slightly beaked hinder side. Posterior dorsal slope decided, eventually retuse. Ventral margin everywhere arcuated, not distinctly retuse posteriorly. Front dorsal area flattened, manifest. Lips of the escutcheon, which is not sharply defined, but gradually concave at the circumference, pouting. Interior bluish-white.

Anterior side a little the shorter, unsymmetrically rounded, its dorsal edge short, slightly convex, and a little sloping. Hinder dorsal edge incurved, horizontal, forming a blunt angle with the posterior edge, which is arched above but more rectilinear and obliquely sloping inwards below, so that the upper corner is far more prominent than the rounded lower extre- mity.

Margo ventralis arcuatus, haud sinuatus. Arez dorsales haud definitee.—Narrow-oblong, ventri- cose, scarcely gaping, with a shining olivaceous-yellow epidermis, smooth except for the wrinkles of growth, devoid of umbonal ridge or defined dorsal areas. Anterior side much the shorter (about two-fifths of the entire length), its extremity well rounded. Posterior side gradually attenuated to a rather narrow but well rounded tip: its dorsal edge straightish and subhorizontal near

L. sutcrrera, Reeve, f. 165, 166.—T. subzequilateralis, sub- angusté ovata, nisi ad umbones gibbosos compressa, antice rotun- data, posticé obtusé rostrata et paululum flexuoso-concava; cute corneo-virente induta, sulcis remotis longitudinalibus vix insculpta. —Somewhat narrowly ovate, compressed, yet rather gibbous at the umboes, subequilateral, rounded in front, slightly flexuous-con- cave and bluntly beaked behind. Surface with distant superficial longitudinal grooves. Epidermis greenish horn-colour.—Never having seen this shell, the description is not original.
NUCULA, Lamarck (restricted).
Gen. Char. More or less subtriangular, very inequilateral, closed at one and usually at both ends, clothed with an epidermis : um- boes turned to the shorter side.* Inside pearly; margin some- times crenulated: hinge-margin with a row of produced and pointed interlocking teeth on either side of the projecting support for the narrow triangular cartilage-pit, which slants to the longer side. No pallial sinus.
Sect. A. Ventral margin crenulated.
1. N. pecussata, Sowerby, f. 109, 110, 111.—T. valida, vix obliqua, longitudine latitudinem multo superante, ad umbones prominentes subrectangularis, subventricosa, cute luteo-virente induta, rugis lamellaribus concentricis lineisque elevatis densis radiantibus arcté et undique decussata. Margo ventralis crassé crenatus. Lunula satis magna, protrusa, externé subgranoso- corrugata, superné levigata. Area subplanulata, sepius trans- versim plicato-corrugata (rugis «tate obsoletis).— Very variable in shape and degree of lateral inequality, nearly rectangular at the beaks, not particularly oblique, much longer than broad, subven- tricose, nearly evenly diminishing in convexity on either side,
* When there is neither a pallial sinus, nor an external ligament, it is usual to consider that side the posterior which contains the larger portion of the eartilage, and that the anterior towards which the beaks incline. The position of the animal in Nucula, however, compels me to term the shorter end the posterior. The words /unule and escutcheon are here used with their ordinary signification, and not as equivalent to front and hinder dorsal impression.

covered by a thin greenish oil-coloured epidermis, everywhere (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

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- formis; postica inferné rotundato-excisa. Nates peracute, in- 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.

Nates seepius erosve. —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.
13. N. putcura, Hinds, f. 146.—“ T. elliptica, solida, sulcata ; interstitiis transversim striatis; marginibus ventralibus crenulatis ; cardine anticé (7.e. posticé) dentibus 9, posticé 27-29. 7 lin.” —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.

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.

Sculptura nonnunquam ad umbones obsoleta ; lire 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- tinct ; lunular area rather more angularly depressed, and slightly more projecting below (f. 160, 161).

Lunula magna, profunda, costellis parvis densisque transversim ornata, angulo circumscripta: angulus divaricatim sculptus.—Truncated- 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.

Hinder side not so short as usual, subangular and prominent at its extremity. Ventral margin regularly arcuated, not sinuated, coarsely crenated within. Beaks peculiarly high, and laterally compressed. Hinge-margin broad: teeth few (ten and six) ; pit minute, perpendicular.—Pos- sibly immature, but strongly characterized.

Ventral 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, and worn smooth. ‘There seem some close lamellar wrinkles upon the lunule, but of this I am not sure.

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 species to M.

Anterior side rotundately obtusangular above, the dorsal edge being horizontal and straightish, well rounded below ; posterior side long for the genus, rotundately acutangular, the peak subcentral, the dorsal slope straightish, not abrupt: chief breadth subcentral. Ventral margin entire, much arcuated, much rising behind. Beaks not much projecting, yet conspicuous from their acuteness. Dorsal areas undefined, yet somewhat concavely impressed. Lunular lips carinately pouting.—The hinge resembles that of ¢enwis, but the teeth seem scarcely so numerous. I doubt, however, the ma- turity of the examples.

* The WN. tenuis of Gould (Invert. Massach. p. 105, f. 64.—Dekay, N. York Moll. 181), described from scarcely matured examples, is exactly intermediate in characters 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.

Lunula inferne planulata. —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.

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.

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.

As Mr. Hinds omitted to figure it, and the definition is wholly inadequate, the species may be regarded as too uncertain to be retained.

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.

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.

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.

+ 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.”
Species of Galeomma. Plate 234.
1. G. Turront (f. 1, 2, 3, 4), Sows.—Testa oblonga, alba, ad latera oblique subtruncata, terminis acutis, striis elevatis duplicatis et divaricatis moniliferis sculpta, striis ad marginem dorsalem ad- scendentibus, margine ventrali validé hiante; cardine edentulo. 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, oblonga, subquadrata, concentricé undulata; latere antico breviore, truneato. Ods. A rather flat, thin white shell, truncated at both extremities, slightly open in front.
175 SCINTILLA.
4. Sc. ampieua (f. 1, 2, 8, 4).—Testa pallidé aurantia, tenui, oblong’, depresso punctulato, prismatici, subdiaphana, subin- flata ; latere antico subtruncato, postico rotundato, majore ; margine ventrali hiatu mediocri; dente antico in valva simistra bifida.

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- tral opening is the principal difference between this and Se. ambigua.

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.

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- truncata, paululum lhiante; margine ventrali clauso, recto. Obs. This fine shell is shghtly open at the extremities and dorsal margin.

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 apex and in the centre, thicker, more opaque and yellowish to- wards the margin.
22. Sc. soripuLa (f. 48, 49), Desh.—Testa ovali-subquad- rata, solida, pallidé fulva ; latere antico breviore ; terminis obli- qué subtruncatis. Ods. Similar in form to S. scintidlans, but not so glassy or shining, more truncated, and of the same thick- ness and colour throughout.
23. Sc. ovurina (f. 47), Desh.—Testa quam Se. solidula magis tumida, angusté et truncata. Ods. A rather narrower, more tumid and more truncated shell than Se. solidula.
24. Sc. rurcescens (f. 45, 46), Desh.—Testa alba, solida, ovali- subquadrata, valde inflata; margine ventrali recto; margine dorsali declivi; terminis truncatis; apice tumido. Ods. A very tumid white shell, with straight ventral margin and truncated extremities.
25. Sc. rurema (f. 51, 52), Desh.—Testa alba, tenui, inflata ; latere antico brevi, truncato, latere postico tumido, rotundo; mar- gine dorsali elevato; margine ventrali posticé inflato, anticé con- tracto. Ods. This differs from Se. ¢wrgescens in being thinner and having the posterior side much more inflated than the anterior.
26. Sc. Dusnaynsir (f. 50), Sows.—Testa alba, pellucida, in- flata, ovali-subquadrata, concentricé undulata; apice rotundo; mar- gine dorsali utrinque declivi; terminis subtruncatis; margine ventrali subrotundo, latere antico breviore. Obs. I am “obliged to change this name on account of the removal of the species named by Deshayes Galeomma Layardi into this genus.
27. Sc. pisum (f. 54, 55), Sowd.—Testa parva, lutea, semi- pellucida, clausé, subovali, tumida, concentricé leviter striata ; latere antico brevi, latere postico inflato. Ods. A small inflated yellow shell, with the posterior side more inflated than the anterior.
28. Sc. succrnea (f. 58), Desh.—Testa fusca semi-pellucida, quadrata, compressa, clausd; apice tumido; margine postico late- rali obliquo. O#s. Rather flat and nearly square.

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 obscuré radiatim fasciata, depressd, anticé paululum attenuata, costellis irregularibus moniliferis radiata, intus alba; margine lato, pallidi subviridi; foramine parvo, ovali. Ods. The irregularity of the nodules, and the less conical form, independently of colour distinguish this from the preceding. /. rudis of Deshayes, may
188 FISSURELLID®.
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 ;

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 laté fasciatd ; apice elevato; foramine subcentrali, rotundo. Oés. 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-

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 marked by green lines.

aperturee minuté denticulato; foramine brevi, declinato. Ods. Regularly radiated with close, equal, scabrous ribs.
95. virtpuna (f. 62), Lamk.— Ovali, subarcuatim elevata, viridi vel fuscd; costis radiantibus, rotundis vix nodulosis, quarum 20 albis extantibus, et alteris intermediis fuscis vel viridis minori- bus; intis albo margine crenulato, prope apicem subceruleo ; callo nigro-marginato; foramine angusto, medio coarctato. Obs. A beautiful species, with radiating white ribs and three ribbed green or greyish-brown interstices.
96. recuLa (f. 57), Rve.—Parva, oblonga, crassi, posticé ar- cuatéi, anticé brevi, declivi, grisedé, nigro radiat&; inter radios nigros costis depressis, quarum posticis majoribus radiatis ; intis pallidé griseo, aperturee margine minuté denticulato nigro, eallo nigro-marginato ; foramine oblongo. Ods. Small, narrow, arched, grey with black rays between smooth depressed ribs.
97. Lincotnt (f. 133), Grey, Sowb.—Ovali, alba, arcuatim elevatd, anticé paulo angustiore, marginibus laqueatis extantibus concentricé lirata, costis scabris et fasciis purpureis radiaté ; intus albo, callo circulari, tumido ; aperture margine denticulato, macu- 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 ; concentricis, et costis numerosis angulatim nodulosis scabris ; ints pallide ceeruleo ; callo rotundo, tumido ; margine apertura: duplica- tim denticulato; foramine rotundo, supra medium posito, antice declinato. Ods. A darkly-coloured shell roughened by concentric fringes and angularly-knobbed ribs.
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.
100. prerraLe (f. 122), Rve.—Ovali-subrotunda, obliqué ele- vata, striis minutis scabris radiata; apice validé versus marginem anticum inclinato; olivaced, prope apicem subceerulea, intus alba, versus callum griseA; margine olivaceo; foramine parvo. (ds. Finely reticulated, greyish-olive, much inclined anteriorly, with a small rounded fissure.
FISSURELLID®. 199
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.
104. crpperuLa (f. 113, 117), Zamf.—Oblongi, posticé at- 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, fulvo radiata, radiatim minuté striata, antice angusti; apice versus marginem anticum declinato; dorso gibboso, arcuato ; margine ventrali arecuato; foramine parvo. Ods. Small, white, with fawn- coloured rays, much inclining forward, and having a curiously- arched and gibbous back.
107. minvuta (f. 169), Sows. G. B. 2.—Parva, elongata, dorso 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 F. minuta, and has not the arched back nor the black-edged foramen of that species.
109. aneustata (f. 170, 171), Sows. G. B. 2.—Hlongata, angustata, dorso arcuato, alb’, nonnunquam fulvo radiatim fas- ciaté, minuté cancellaté; foramine parvo, circulari. Ods. Differ- ing from the preceding in the smallness of the foramen and in the narrow and arched form.
110. roa (f. 181), Sowb.—Oblonga, dorso arcuato, alba, an- gulatim olivaceo variegata, costis scabris numerosis et alteris mino- ribus alternis radiaté; intts pallidé ceeruleo; margine denticulato, ad latera elevato, arcuato ; foramine rotundo, validé antico. Ods. An 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 radiantibus moniliferis alternatim majoribus, quarum nonnullis nigro articulatis, cancellaté; foramine elongato, longé supra medium posito. Ods. A beautifully sculptured and figured species in the collection of Mr. Hanley, in which some of the most prominent ribs at regular intervals are articulated with black.

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 elevated and the ribs sharper and closer than (although not so prominent as) in F. @gis. Obs. It is white, radiated by four brown bands.
119. tentrerosa (f. 190), Rve.—Ovali-oblongé, subdepressa, costis scabris alternatis crebris radiata, alba, griseo fasciatim macu- lata et variegati; intis grised; margine denticulato; foramine magno, rotundo. Ods. Rather more gibbous than the three pre- 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- longa, posticé depressd, anticé gibba, fulva-grisescente, striis impres- sis radiata ; striis concentricis crenulatis ; ints alba; callo apicali valido; margine crenato, aperture margine denticulato, ad latera

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 striata, costis complanatis et interstitiis minoribus radiata, intis alba; callo valido ; foramine magno, ovali, subcentrali.

FISSURELLID®. 203
posito. Oés. A very pretty shell in Mr. Hanley’s collection, in some respects resembling F. Chemnitzii, but much thinner, and 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- angustato. Os. The upturned edges of this almost square species seem to place it in this genus or group.
7. nicriva (f. 196), Sowb.—Oblonga, depressa ; lateribus com- pressis, terminis elevatis; radiatim striata, migrA; foramine maximo, ovali, centrali. Ods. Black, finely striated, with the ends raised, and very large central fissure.

B. 2.—Oblonga, depressa, alba, terminis paululum elevatis, lineis impressis radiat&, con- centricé crenulatim minutissimé striaté ; ints margine incrassato, crenulato, callo lato circumscripto; foramine maximo, ovali, cen- trali. Obs. A thick shell with ends slightly elevated, and very large fissure.
9. tiraruta (f. 204), Rve—Oblonga, depress, striis impressis 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.

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.
2. FascrcuLanis {f. 212, 213, 214), ZLamk.— Sub-pyriformi, gibbosa, anticé silboounineteeve radiis rugosis, elevatis radiata ; foramine subcruciformi, prope medium posito. Ods. Peaked in 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, obsolete bicostati; margine antico validé elevato, sinuato, intis margine incrassato ; foramine anticé angustato.

8. niatuLA (f. 198), Swaznas.—Oblongo- subquadrata, radiatim 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- lim angustato obscuré quadricostato; foramine magno, supra medium posito. Ods. Not quite so broad as the preceding, and having the feramen rather nearer t! e front margin, with the space between slightly depressed.

MONOGRAPHS OF THE GENERA
CEMORIA, CRANOPSIS, ZEIDORA, RIMULA, EMARGINULA, SCUTUS, & TUGALIA.
By ARTHUR ADAMS anv G. B. SOWERBY.
Note.—Owing to engagements interfering to prevent the completion of Mr. Adams’s manuscript, the arrangement of these monographs and final decision respecting many species has fallen into the hands of G. B. S.
The specimens are nearly all from Mr. Cuming’s collection.
Genus CEMORIA, Leach. Pirate X.
Char. Gen. Conica, radiatim costata, apice centrali; fissura ad apicem posita, fornice interno arcuato.
In this genus, which is Sipho of Brown, Puncturella of Lowe, and Rimula of American conchologists, the foramen is situated at the apex of the shell, and is not simple, as in F%sswred/a, but is furnished with an internal arched process.
1. noacuina (f. 10, 11), Zinn.—Conica, apice obliqué per- forata, foramine intis coarctato, marginato ; costis minimis, ine- qualibus, radiantibus ; apice minimo retorto.
2. gaLwata (f. 12), Goudd.—Solida, cinerea, elevata, globoso- conica, apice central, acuto prorsum, porrecto, stris filiformibus contfertis radiata, et striis minoribus concentricis decussata ; fis- sura brevis, fusiformis; apertura rotundato-ovalis; margine ex- panso acuto, minutissimé crenulato ; fornice costa transversalt anticé suffulto, fossam trigonalem utroque latere formante.

VOL. Il. 206
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- ribus alternantibus radiata, et striis concentricis confertis muri- cata; apice elevato, acuto, adunco, prorsum spectante ; fissura lanceolata; apertura ovata, margine sulcis ineequalibus alternan- tibus crenulato ; facie interna porcellana ; formice tenui, simplici, arcuato.

Ods. Resembling C. cucullata of Gould, but with the ribs stronger, wider apart, and equal; the apex, moreover, is considerably more elevated and acute.
6. coenira (f. 13), Goudd.—Comca, alba, radiatim costulata ; apice incurvato ; apertura rotundato-ovali. Ods. Similar to Ce-
moria conica, D’Orb., but less elevated and the ribs more regular (Gould).
7. Fatxtanpica (f. 14), 4. d4dams.—Albida, conica, apice incur- 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 ribs.
8. rastrerara (f. 15, 16), 4. ddams.—Albida, elevato-conica, nitida, vertice acuminato involuto, costellis longitudinalibus eequa- libus equidistantibus, interstitiis plamis lineis incrementi concen- tricis; fissura lanceolata; apertura ovalis, margine crenulato, for- nice costa valde arcuata, transversal, simplici.

FISSURELLID%. 209
In this genus the position of the foramen is the same as in Rimula, but is furnished with the internal calcareous arch pecu- liar to Cemoria.

Hist. 1860. —Pileiformis, liris radiantibus crenulatis, interstitiis cancellatis ornata; fissura inthis concamerata, marginibus callosis extts la- biis elevatis longitudinalibus marginatis ; foramine lineis incrementi transversis apicem versus currentibus, margine crenulato.
Genus ZEIDORA, 4. Adams. Puatr X.
Char. Gen. Testa oblonga, depressa, extiis cancellata, apice pos- tico, margine antico fissurato, imterné lamina septiformi trans- versa instructa.

Odés. This species differs from Z. calceolina in being much more convex, less obtuse anteriorly, and in the fissure being narrow and deeply incised; the sculpture moreover is very different, being finely reticulated instead of widely cancellate.
2. catceoLina (f. 3), A. Adams.—Oblonga, lineis elevatis concentricis et radiantibus eleganter cancellata; sulco mediano lateribus elevatis ; apice posticé deflexo; septo margine acuto in- tegro.

FISSURELLID®. 211
to form in the adult a fissure in the front edge of the shell; in 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.)
1. pranurata (pl. x. f.-1), 4. ddams.—Hlongato-ovalis, com- planata, vertice subcentraii posticé inclinato, albida, costellis radiantibus eequalibus, imbricato-asperis lineisque concentricis incrementi decussata, basi arcuati; aperture margine anticé valde inciso, incisurd lata et profundi.

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.

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,

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.

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.

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.

Cab. v. f. 1691-2, copied as 8. granulatum ? in Kuster’s Chemnitz) have figured So/aria, which closely resemble the more mature examples.

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.

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.

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.

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.

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.

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.

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.

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.

The most distinguishing 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- tonica section.” Possibly an abnormal form of 17.

Unknown to 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.

In the only recent example (brilliant in colour, semi- 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.

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 following description :—‘'l’. orbiculata, convexo-depressa, spira planiuscula ; fusco- nigra, albo radiata ; anfractibus 5, liris conspicuis densé granulato-crenatis, confertis cinctis: ultimo rotundato, suleis 2, latioribus juxta umbilicum patulum obsoletis ; apertura circulari, peristomatis acuti marginibus callo tenui junctis.” 5% lin. “ Al- lied to tnfundibuliformis.”

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.

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 ):—
“'T’. eloboso-conica, albida, in mediis anfractibus fusco macu- lata seu tessellata; anfractibus convexiusculis, sulcis 3 seu 4 1m- presso-punctatis exaratis, ultimo anfractu terete sulcis 10 exarato ; umbilico angusto, margine obsoleté crenulato, intus cingulis spi- ralibus 4 munito.” 3-35 lm.

The shell is figured in Philippi’s monograph (Kuster, Sol. pl. 4, f. 2).

In- termediate examples will probably demonstrate the unity of this and eyclostoma. Menke, who founded his species upon a young shell, has so ill defined it, that the name has usually been as- ceribed to the dark form of perspectiviunculus.

This species closely resembles the pre- ceding, but is more solid, with the periphery more bicarinated. The mouth, from the slow volutional increase, is very small. In the variety (?) sérzgata (f. 94) there are 3 approximate narrower, and 3 broader belts under the lower peripherial one ; the threads, if any, are most minute: there are 4 or 5 ridges on the umbilical wall.

* Jn the ‘ Zeitschrift fiir Malakozoologie,’ 1850 (p. 171), Menke has described as nearly related to this species a Mazatlan shell which, if not this doubtful variety, is entirely unknown to me. The somewhat rude figures he refers to (Chemnitz, v. f. 1708, 9; Geve, f. 275) as illustrative, which are almost universally accepted as repre- sentations of perspectiviunculus, do not exhibit the patulous umbilicus he especially indicates. His generic allocation is, likewise, peculiar. ‘‘ EuOMPHALUS RADIATUS. B. testa orbiculata, convexo-depressa, spira planiuscula; fusco-nigra, albo radiata; anfractibus 5, liris conspieuis densé granulato-crenatis, confertis cinctis: ultimo ro- tundato, sulcis 2 latioribus juxta umbilicum patulum obsoletis; apertura circulari, persistomatis acuti marginibus callo tenui junctis.

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.

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- fractibus levissimis, superius carinato-angulatis, supra carinam planis, infra eam plano-declivibus; ultimo in peripherii acuté carinato : umbilico laté infundibuliformi, striis elevatis radiantibus concentricisque cancellato, in ambitu crenulato: apertura exacteé rhombea. 1-14 lin. Chinese seas.” Judging from the figure, I much doubt its bemg a member of this genus.
nanum, Koch, Zeit. Mal. 1851, teste Philippi, in Kust. Chemn. Sol. pl. 4, f. 5.—“T. depresso-globosa, alba, strigis radiantibus rufis picta; anfractibus rotundatis, superius angulatis, cingulis elevatis subgranulatis cirea 4 in anfractibus superioribus; basi levi; umbilico mediocri, infundibuliformi, margine crenato, intus striis elevatis radiantibus et concentricis granulato-decussato ; apertura subrhombea. 23-3} lin. Chili?”
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.

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.

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.

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

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-

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.

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

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.

Testa involuté discoidea, unilocularis, papyracea, minuté granu- lata, alba seu pallida, disci margine nigrescente ; anfractibus bica- rinatis, tuberculatis ; lateribus radiatim liratis ; spird immersa.
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.
Description of the Species (the Shells). Plates 257, 258.
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.

3. TuBERCULOSA (f. 3), Zamk.—Testa convexa, rotunda ; rugis : 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.

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 ; pallida, maculis distantibus ad suturam quadratis, ad medium an- fractum longitudinalibus bifasciata; apertura auritd, posticé vix acuminata. Oés. The outer lip is more rounded at the top and the striz more regular and equal than in P. awritus. A row of

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.

11. patirpa, Gray.—Should be Vorva, Chem., by priority. (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.

9. mucronatus (f. 34) should be Gzorcinm, Gray. I give a more mature specimen to complete the representation with f. 23, 28.
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.

Sect. III. Labro supra et infra tumido, sinuato.
In this section a swelling and bending forward of the outer lip above and below, which in H. /ineata (f. 35) amounts almost to a tooth in the lower part, leads by gradation into the group called Lucripetta.

282 HELICINA.
Sect. IV. Zrrata, labro sinuoso, supra et infra dentato.—Genus Lucipeta, Swainson.
The swelling of the labrum above and below, forms tooth-like 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.
57. unpuuava, Pfr., (f. 92, 93.)—Undulatim striata. —Undu- lately striated.
58. inmquauis, Pfr., (f. 95.) —Angustata, elevata.—Narrow, subconical.
59. rripens, Shutél., (f. 90, 91.)—Carinata, labro tridentato.— Keeled, outer lip three-toothed.
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.
61. crasst-costava, Sowd., (f. 97.)—Crebré lirata, labro lami- nate, columella rect’.—Closely ridged, outer lip laminar, colu- mella straight.

65. nxcavata, Pfr., (f. 106, 107.)—Columella laté concava. —Columella wide, concave.
66. remora, Po., (f. 108.)—EHlevata, col. angusta.—Hlevated, col. narrow.

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 antico declivi, ad terminum acuminato.—Nearest in form to D. scortum, but a polished shell.
3. acuticarinatus (f. 6, 7), Sows.—Testa D. carinate simili, haud tantum elevata, carina validiore, arew postice stris radian- tibus granulatis.—Besides the greater distinctness of the keel, the sculpture of the posterior area distinguishes this species from D. carinata, the radiating strie being close, and crossed by con-

A short elevated shell, smooth in front and ornamented at the back with ridges decussated by radiating strie. D. sordida, Rve., appears to be a variety of this, partly denuded of the sulci and serrations.

13. acuminatus (f. 14), Desh.—Testa D. semisuleate forma simili, sed postice minimé granoso-striataé, angulo vix serrato.— The want of posterior sculpture alone distinguishes this from D. semigranosa.
14. mera (f. 17), Reeve.—Testi D. semigranose simili, sed magis obtusi, ad angulum semi-rotunda, vix serratié.—More obtuse at the apex and posterior angle than D. semisudcata, the angle not serrated nor keeled.
15. ryrro-rapiatus (f. 25), Reeve.—Testa brevi, elevata, cuneiformi, acuté angulatd, carinaté, pallida, extus obscuré, intus valide, prope umbones purpureo trifasciaté, radiatim striata, post- angulum densé rugoso-decussat’i.—This shell would resemble a small D. Cayennensis, but it is sharply keeled posteriorly and pointed in front. The purple rays are bright within, but dull without.
16. asper (f. 24), Han/.—Testa solida, albi vel purpurascenti, subeequaliter trigond, anticé radiatim striata, posticé prope an- gulum granoso-sulecaté, post angulum striaté, margine postico ventrali denticulato, are postangulari infra convexa, supra con- cava, umbonibus elevatis, latere antico valde declivo.—An elevated, solid species, nearly equally trigonal, grained near the angle.

The ven- tral margin of the right valve appears a little beyond that of the left, showing the strong dentition at the posterior side.
20. curtrus (f. 20), Sowh.—Testi D. Cayennensi simili, sed longé magis abbreviaté.—The abbreviated form of this shell is so constant through all the varieties of colouring that after examining a number of our own specimens with Mr. Taylor’s we have no hesitation in distinguishing it.
21. RnuGosus (f. 27, 28, 29), Linn.—Testd elongata, tumida, crassa, luteo-purpurascente, seu aurantio-rosea, seu late fasciata, latere antico subacuminato, prope marginem levi, medio et postice radiatim striata, latere postico brevissimo, undulatim rugato, stris radiantibus decussato,angulo subcarinato, ared postangulariconvexa. —Of an elongated form and rugosely decussated behind the angle.

There is no reason to doubt the identity of Deshayes’ Lamarchic with this.
26. saxutum (f. 110), Reeve-—TestA D. contuse simili, sed striis elevatis radiantibus sculpta, posticé valdé declivi, angulata. —Differing from D. striata in the ridge-like striz with which it israyed. It is also more angular and truncated posteriorly.
27. vaniaBiuis (f. 387, 38, 39), Say.—Testd parva, tumida, tenuistriata, varié picta, anticé oblong’, prope marginem attenua- tim acuminata, posticé leviter angulata, area postangulari convexa, margine ventrali medio convexo.—A little, tumid, finely striated shell, variously coloured, distinguished by a peculiar pinched and pointed appearance towards the anterior extremity.
28. Bens (f. 40, 41), Desh.—Testa oblonga, tenuiter striata, albi fulva seu purpureo radiata, postice brevi, declivi, obtuse angulatd, margine ventrali rectiusculo.—Resembling D. variabilis, but gradually sloping in front, with the ventral margin rather straight.

32. opesus (f. 42, 43), D’ Orb.—Testa parva, abbreviata, crassa, tumida, trigond, alba, fulvo fasciati, seu purpurea, lineis dorsali- bus purpureis ornata, minutissime punctato-striat4; umbonibus elevatis, latere antico acuminato, latere postico angulato, area postangulari angulatim convexé.—This remarkable little species is sculptured by punctured striz, not concentric, crossing the radiating stric.
33. puNcTATO-sTRIATUS (f. 49, 50), Han/.—Solida, ventricosi, trigond, striis punctatis radiata, albidé carned lilaced seu pur- pureo-radiaté, umbonibus elevatis tumidis, angnlo postico obtuso plus minusve declivi, arei postangulari rectiuscula, prope margi- nem ventralem rotundatim producto, prope umbones complanato ; latere antico attenuatim acuminato, margine ventrali medio in- flato, posticé ante angulum subcontracto.—An easily distinguished, stout shell, with characteristic strongly-punctured grooves or striz.
34. Conrant (f. 51), Desh.—Testé D. punctato-striate simili sed magis depressd, posticé magis angulatim productd, anticé magis elongatéa.—It is not quite easy to distinguish this species from the last, on account of intermediate specimens. It is how- ever flatter, not so pinched up in front, and more produced be- hind.
35. contusus (f. 53, 55), Meeve-—TestA quam D. Conradi magis compressi, haud tantum ineequilaterali—The three last species, punctato-striated in the same way, exhibit a perplexing gradation m degree of flatness and production of the posterior side.
36. Catirornicus (f. 54, and var. D. culter, Reeve, p. 56, 57), Conrad. —Testa oblonga, subeequilaterali, minutissime punctato- striata, superné sublaevigata, alba, pallidé purpureo radiata vel sub- viridi, ad umbones carned, purpureo nebulata, obscure biradiata, postice producta, obscuré biangulata, area postangulari convexa, elevata, anticé attenuatim subacuminaté, margine ventrali prope angulum subcontracto, ante medium plus minusve convexo.— 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.
37. petroipes (f. 100, 101), Lams.—Testi magna, solida,
DONAX. 311
brevi, alta, obtusé angulata, purpurea seu pallidé violaced, anticé leevigata, rotundatim acuminata, posticé lat’, tenuiter striata, margine ventrali medio subconvexo, angulo postico obtuso, area 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- uscula, pallidé purpurascenti, posticé obtuse angulatd, rugata, anticé attenuata, subacuminata, latere antico-dorsali incurvo, um- bonibus acuminatim producto-subrotundatis.— Remarkable for the acuminately produced umbones, and the incurved character of the anterior dorsal slope.
39. cunEatus (f. 88, 89, 90), Zanv.—Testd obtuse trigona, compressa, levigata, alti, alba vel fusco-nigricanti vel carneo- fulva, postice obtusé angulata, post angulum undulatim granoso- rugata, margine ventrali intus levigaté.—A broad compressed 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.
42. Bicotor (f. 102, 103), Lams.—Testa ovali-subcuneata, compressi, anticé et medio levi, posticé granulatim striati, alba, laté fusco-grisescente fasciaté, vel grised, obscuré fusco radiata, posticé obtusé biangulata, margine ventrali convexa, intus levi- gata, are postangulari concava.—The posterior side of this shell has a very obtuse angle in the usual part, and a second angle in the middle of the area; the area is granosely striated.
43. rncarnatus (f. 98, 99), Chemn.—Testa brevi, compressa, elevati, carnea seu alba, purpureo ad umbones radiata, anticé leevissimi, subacuminata, postice rectiusculd, ante et post angulum striis radiantibus et rugis subconcentricis undulatis decussata ;
312 DONAX.
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- trigona, brevi, coloribus variis fasciaté et maculata, anticé et medio sublevigata vel leviter lirati, posticé validé rugata, angulo postico obtusissimo, area postangulari convex4, margine ventrali prope 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, compressi, alta, laevigata, grisea vel alba, roseo trifasciatd, posticé brevi, rugosi, obtusissimé angulata, margine antico-dorsali declivi, margine ventrali convexo, intus levigato.—Flat, almost rounded, with granulated, undulating ridges on the back area.
47. ovatinus (f. 104), Desh.—Test’ compressd, ovato-subro- tunda, laevigata, cinered vel radiatim maculata; latere antico brevi subrotundatim convexo, margine ventrali rotundato, intus levi. A rounded, flat, Tellina-lookmg shell.
48. nucuLoies (f. 105), /eeve.—Subovata, plano-convexa, albida, epidermide subviride nitente induta, latere antico subro- tundo, margine antico-dorsali declivi, margine ventrali convexo, posticé prope angulum parum contracto, intus levigato, latere postico obtusé angulato, margine convexo.—Another ‘ellina-like species, without markings and more oval than D. ovadina.
49. incpratus, (f. 112), Reeve-—Test& subovata, tenuissima, levigata, pallidé carneo-rosea, latere postico brevi, subrotundato, subflexuoso, margine ventrali medio inflato, prope terminos sub- incurvo, intus levi; latere antico declivi, acuminato.—l have not had the opportunity of examining this neat little shell, which was originally drawn from a single valve in Mr. Hanley’s collection.

50. opscurus (f. 111), Reeve.—Testd D. nueuloidi simili sed concentricé striata.x— Without re-examination of the two shells, 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, lata, carne purpurascenti, levigatd, anticé rotundatim oblonga, margine ventrali concavo, intus crenato, posticé subcontracto, angulo postico obtusissimo, rugis denticulatis serrato, ared post- angulari concavi, umbonibus obtusis.—A thick, oval shell, very obtuse at the extremities and angles, and serrated at and behind the angle by denticulated ridges.
52. TruNcutus (f. 58, 59, 60), ZLznn.—Testi elongato-sub- trigona, compressi, solida, levigaté, obscure radiatim striata, alba vel purpurascente, fulvo seu purpureo fasciata, anticé elongata, lata, rotundata, concentricé leviter rugati, posticé brevi, convexa ; margine ventrali medio convexo, posticé subcontracto, intus den- ticulato, valvi dextrd alteram superante, margine dorsali declivi, 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, obscurissimé striata, truncata, liliaceo radiata, valvis supra et infrd parum inequalibus, latere antico producto, rotundo, latere postico truncato, margine ventrali posticé subcontracto, ared postangulari brevi, concava.—The contraction of the ventral margin near the posterior angle, whence this shell derives its name, is a variation common to many species. ‘I'he curious inequality of the valves at the two margins observed in the last 1s shown in a less degree in this.
54. virratus (f. 66, 67, var. semistriata, £70), Da Costa.— Testa ovali, gibbosa, solida, luted, fulvo laté radiata, purpureo fas- ciata, anticé politd, medio et postice minute radiatim striata,ad angu- lum et ante usque ad medium lineis impressis punctatis subconcen-

tricis plus minusve decussata, ared postangulari declivi convexa, 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- nati, glaberrim’, albo roseo lividove radiati, postice brevi sub- truncata, antico rotundo, oblongo, margine ventrali arcuato, intus crenulato. —I'his much resembles a flattened form of D. ¢runculus.
57. nivipus (f. 75), Reeve.—Testa elongata, compress, tenui, fulvo triradiata, anticé producti, prope marginem levigata, posticé et medio rugis concentricis prope marginem rectiusculis liraté, margine ventrali rectiusculo, intus denticulato.—This little 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- vexo, postice subacuminatim producto, margine ventrali levi.— The young shell figured by Reeve under the name D. variegata evidently belongs to this well-known species,
59. Gracius (f. 76, 77, 78, 79), Hand.—Testa angusta, crassa, elongata, tumida, alba, hlace&, violaced, obscure fasciata, radiatim tenuissime leviter striaté, margine dorsali purpureo lineata, antice elongata, acuminata, margine ventrali medio convexo, intus cre- nato, post medium subcontracto, postice producto, obscuré an- gulato subacuminato.—A beautifully-formed elongated shell.
60. navicuta (f. 80), Hand.—Test& quam D. gracilis magis inflata, latiore, epidermide viridi indutd, margine ventrali magis convexi.—A much broader shell than D. gracilis.
DONAX. 315

62. mnnus (f. 83), MZdrch—Testd parva, angusté oblonga, semipellucidd, iridescenti, tenuissimé striati, pallidd, purpureo bifasciata, antice producté, subacuminata, margine ventrali parum convexo, posticé vix contracto, latere postico acuminatim producto. —Looking at this shell under the lens, a peculiar iridescence may be seen and very minute striz.
63. prratinus (f. 86), Dess.—Testd tenui, trigono-oblong4, levigaté, purpureo et fulvo radiatim fasciata, anticé angusta, acuminataé, medio subcontracta, posticé tumida, lata, elevat&, sub- quadraté, umbonibus fere medianis, margiue ventrali intus cre- nato.—A pretty little petal-like species.
64. sproutum (f. 116, Plate IIL), Han/.—Testai quam D. pulchella solidiore, magis opaca, intus purpured.—Resembling D. pulchella form, but more solid and opaque. It is strongly purple within.
65. rnconspicuus (f. 117, Plate IIT.), Sows.—Testa oblongo- cuneati, complanata, leevigataé, fusci, obscuré purpureo radiata, anticé producté, subacuminata, posticé angulata, minuté radiatim striati, ared postangulari convex’i.—Several specimens of this, in 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.

Ad., (f. 18, 19).—Subfuseus, fusiformis, canali obliquo, longiusculo ; spira elevata, varicibus expansis, supra termine incurvis acuminatis, medio angulatim laqueatis, ad canalem semipinnatis ; tubis elongatis.— Varices hooked at the end, angularly fluted in the middle, half-pimnated on the canal.
8. coronatus, Brod., (f. 6, 7)—Oblongus, pallidus; canali Jatissimo cylindraceo, oblongo, truncato ; varicibus crassis decum- bentibus, spiraliter rugatis, termine uncinatis; tubis brevissimis. —Of a more oval form than most of the other species, with a very wide, cylindrical canal, thick varices, and short tubes. The unique specimen in the Cumingian collection being young, the canal is unclosed.
9. prnnatus, Brod., (f. 15, 16).—Ovalis, albidus, cancellatus ; canali brevi; varicibus expansis, fimbriatis.—Oval, whitish, can- cellated ; canal short, varices expanded, fringed.
10. Cumreu, Brod., (f. 17).—Claviformis, griseus, castaneo maculatus, canali longissimo angusto, recto ; varicibus noduliferis, termine unidigitatis, erectis; tubis brevibus; anfractibus inter varices unicostatis.—Shaped like Murex haustellum, with very long straight canal.

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.

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.

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.

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.
