PHILADELPHIA: Published by the Author, /%’ ACADEMY OF NATURAL SCIENCES, Cor. ISTH & RACE STs, 1882. BG THe Fourth Volume of the Manual of Conchology contains monographs of four important families, embracing genera of which many representatives are included in the cabinet of every collector of marine shells. It is hoped that it will be found useful in facilitating the identification of specimens, as well as in correcting the hitherto very confused synonymy. The kind offices of many correspondents in furnishing speci- mens (particularly unfigured types), drawings and information concerning the species, are again gratefully acknowledged ; and I am equally indebted to others for their endeavors to promote the sale of the Manual. I shall endeavor to deserve and recom- pense this active interest in behalf of the work by making it as thorough as circumstances will permit. GoW Es. PR: January, 1882.

Margin of operculum serrated or entire. Dentition, Pl. 5, figs. 22 to 25.* The following “subgenera” may be retained as convenient group designations, although the species, varying much in their sculpture cannot always be positively assigned. Subgenus ArcuLariA, Link. Body whorl gibbous on the back ; spire produced ; callus of inner lip greatly extended and covering the spire. Subgenus Nayvia, H. and A. Adams. Shell smooth; aperture with a channel at the hind part continued up the spire. Subgenus ALEcTRION, Montf.

Subgenus Puorontis, H. and A, Adams. Spire elevated, acuminate, whorls ribbed or nodulose, distinctly shouldered ; inner lip smooth, with an extended, thickened callus, outer lip with an external varix. * Messrs. H. and A. Adams in their ‘‘Genera of Recent Mollusca,”’ have made a Genus Amycla in Columbellide, and included in it some species which are decidedly Nassids ; the dentition of one of these errone- onsly placed species, N. (Buce.) cornicula, Olivi (Pl. 3, fig. 24), has been figured by Troschel as a type of that of the genus Amycla, —which he has accordingly removed to Nassidz. + Nassoponta, H. Adams. Shell oval; spire short, last whorl sulcate anteriorly ; aperture sinuated in front, canaliculate behind ; columella callous, plicate anteriorly ; lip acute, thickened and dentate within, with an anterior marginal denticulation.

Dentition, Pl. 3, fig. 26. DESMOULEA, Gray. Shell ovate-globose, covered with a downy epidermis; spire short, conical, apex papillary; whorls depressed ; aperture ovate; inner lip thickened, with a ridge posteriorly ; outer lip contracted, thickened externally, plicated internally. Dentition unknown. Fossil Genera and Subgenera. Subgenus Mo.LoropnHorus, Gabb. (8. G. of Bullia). Short, robust, spire moderately elevated, suture bordered by a more or less distinct carina. Surface longitudinally ribbed or striate. Aperture obtuse behind, and very slightly notched; outer lip simple, inner lip very slightly in- crusted, sinuous, anterior notch small, but distinctly defined. B. striata, Gabb. Pl. 3, fig. 27. Cretaceous, California. Genus PTYCHOSALPINX, Gill. Shell ovate, buccinoid, whorls regu- larly rounded and ventricose; spire moderate (about as long as the aperture), furnished with equal revolving linear ridges, siphonal canal very short, very obliquely twisted and concurrent with the siphonal * H. and A. Adams have also a subgenus Uzita, but its characters are not different from those of Tritia, whilst its species are, many of them, evidently better placed in other groups: a large number of them. for instance, possess the marginal varix, the absence of which is one of the characters of the group. Uzita can be advantageously dispensed with. 8 NORTHITA, fasciole ; aperture rhombo-ovate, oblong; labrum entire, not sinuous, smooth within ; columella inversely sigmoidal, concave near the middle, with a very thin callous deposit and with a revolving linear plait in front. Tertiary, United States and France. Dr. Gill refers his genus to the family Buccinide, but I agree with the late Mr. Conrad that his deseription indicates (as do the types cited) Nassze. - P. autinis, Conrad. PI. 3, fig. 28. Miocene, Virginia. P. scALASPIRA, Conrad. PI. 3, fig. 29. Miocene, Virginia. Subgenus Paranassa, Conrad. Differs from Ptychosalpinaz in the submargin of the labrum being slightly thickened within and striate ; siphonal canal shorter. Eocene, Miocene, America and Europe. P. GRANIFERA, Conr.* PI. 3, fig. 30. Virginia. Subgenus TritrarrA, Conrad. Elongated, subturrited, Jabrum not thickened within. This does not seem to differ generically from the true Nassas; it has very little resemblance to Ptychosalpina. T. PERALTA, Conrad. PI. 3, fig. 31. Miocene, Virginia. [Buxuiopsis, Conrad. Placed by its author at first as a subgenus of Nassa, it was subsequently removed by him to Melanopside. It has some resemblance to Bullia. | j Genus NORTHIA, Gray. The animal of this genus is unknown, but the operculum has been figured by H. and A. Adams, in their “Genera.” The shell is in its general aspect much closer to Pusionella in the family Terebride than to the genera with which it is here (and has been heretofore) associated; the variceal thickening at or near the outer lip, is however, a feature which does not obtain in the Terebridxe. Pusionella, moreover, has a concentric oper- culum, with its nucleus near the middle of the inner margin. Perhaps the figured operculum of Northia is abnormal; it has that appearance. I think that if these shells had not been assigned to the Nassidz or to any other family, I would have placed them in Terebride: as’ it is, I prefer to allow them to remain here, rather than possibly complicate the subject by changing their position. * As one of the two specimens of the type of Paranassa is striate within the aperture, while the other is smooth, probably the distinction from Ptychosalpine will not hold good. ———— ss TRUNCARIA. N. seRRATA, Dufresne. PI. 5, figs. 50, 51. Livid olive, becoming chestnut-colored on the spire ; a hump- like projection often occurs parallel with and just behind the margin of the outer lip. Length, 2-2°5 inches. Panama; St. Elena, W. Col. Gray’s name Buccinum Northiz, has priority, but has not been adopted. Deshayes called it B. pristis because Dufresne’s name was preoccupied in Buccinum for a fossil species—an ob- jection which has no force since the shell has been dismembered from that genus. N. atBopuncTatTa, Adams and Reeve. PI. 5, fig. 52. Light yellowish, minutely punctate with opaque white, apex rosaceous. Length, ‘8 inch. Philippines. N. Rrssomes, Reeve. PI. 5, fig. 53. Whitish, with clouded yellow streaks. Length, ‘9 inch. Philippines. First described as a Plewrotoma. The specimen figured shows a single rib or varix on the body whorl. Adams remarks that N. albopunctata is closely allied to this species: I think it probable that they are identical. Genus TRUNCARIA, Adams and Reeve. This genus is founded on a singular shell discovered during the voyage of the “ Samarang,” and is principally characterized by the abrupt trunecature of its columella, and by its anteriorly dilated aperture. T. rinosa, Ads. and Reeve. PI. 5, fig. 54. Yellowish brown, maculated withtwo or three series of chestnut- brown spots. Length, 1:1 inches. China Sea. T. AustRALIs, Angas. PI. 5, fig. 55. Moderately solid, shining; the two apical whorls thin and papillose, the rest somewhat distantly and flatly longitudinally plicate on the upper portion, the plicze crossed with fine im- pressed lines, the middle of the last whorl smooth, with a few impressed lines near the base; sutures grooved. Pale brown, columellar callus white. Length, 7 mill. Port Jackson, Australia. 2 10 BULLIA. T. ruGATA, Reeve. PI. 5, fig. 56. : Whitish or light brown. Length, 1+] inches. Habitat unknown. The pertinence of this species to the genus is very doubtful. I have not seen a specimen of it. T. MODEsTA, Powis. PI. 5, fio. 57. b] > Yellowish, longitudinally strigate or maculate or nearly covered with chestnut-brown, with a white central band. Length, ‘8-1 inch. Panama. Quite as closely related to Hulhria as to the type of this genus. T. sutcaTA, Kiener. Pl. 5, fig. 58. Yellowish white, under a rufous epidermis. Length, 15 mill. Habitat unknown. 'T. EURYTOIDES, Carpenter. White, with a revolving series of brown maculations on the periphery ; sometimes the base is brown, or the whole surface brown spotted; with about twenty longitudinal riblets, becom- ing evanescent towards the aperture; aperture subquadrate, lip scarcely thickened, striate finely within, columella abruptly truncate. Length, °3 inch. ' Cape St. Lucas, Lower California. Has not been figured hitherto, and the specimen before me (an author’s type) is not in good condition for illustration. Very probably the species is nota Truncaria, at all; its size indicates close relationship with Columbella. T. rrirAscraTa, A. Ad. This name is given in the “ Genera of Recent Mollusca,” but I have not found a description of it. Genus BULLIA, Gray. Animal without eyes ; tentacles long and slender. Foot enor- mously expanded, and bifid behind in the typical species. There is no operculum. Bullia (restricted sense) has a rvaised band of enamel round the sutures of the whorls as in Ancillaria. ‘The animal has the faculty, according to M. Quoy, of absorbing, through the pores of its foot,a great quantity of water, which it ejects when disturbed, BULLIA, a in various directions; it is caught by baiting lines with bits of flesh. The genus is oriental, mostly So. African in distribution, and reminds one of the Arctic genus Volutharpa (vol. iii, p. 197). H. and A. Adams separate a genus Pseudostrombus on account of the want of the sutural band of enamel, and the foot of the ‘animal being simple instead of bifid behind; but as in Nassa, the difference in the animal is not certainly to be regarded as generic; and as to the shell, there is no sharp line of division between species with and those without enamelled sutures—the globose species generally showing the most of it and the narrower ones less. Nevertheless it will be convenient to group together the narrow species as a subgenus. In Woodward’s “Manual of the Mollusca,’ Bullia is erro- neously made a synonym of Anaulax, Roissy, a fossil form of Ancillaria. Typical. B. ba&vissima, Gmel. PI. 5, fig. 59. Yellowish white to brownish red; smooth and polished. Length, 2-5-3 inches. Cape of Good Hope. B. euopunosa, Kiener. PI. 5, fig. 60. Spire shorter, whorls slightly contracted above the middle, suture but slightly, or not at all enamelled. Length, 2°5 inches. Habitat unknown. I doubt whether this is more than a variety of B. levissima. B. DEFoRMIS, King. PI. 5, fig. 61. Yellowish brown, obscurely brown banded. Length, 22-33 mill. Mouth of the Rio de la Plata ; Rio Negro, South America. B. tenuis, Pl. 5, fig. 62. Thin, yellowish white, one or two revolving grooves just below the suture and a number on the lower half of the body whorl. Length, 1°75 inches. Habitat unknown. B. cALLOSA, Gray. PI. 5, fig. 63. Yellowish gray, sutural and columellar callosities generally chestnut-brown. Length, 1°25—-1°5 inches. Habitat unknown. 1g BULLIA. Remarkable for its callous deposit upon the columella, which sometimes is so thick as to give the shell a distorted appearance, producing an angle or hump on the periphery. B. MauritiAna, Gray. PI. 5, figs. 64, 65. Yellowish white, deeper yellow within the aperture; the callous" sutural band frequently opaque white. Length, 1:25-1-75 inches. Mauritius ; Madagascar. B. Mauritiana was not figured by Gray, and his description is so unsatisfactory that the recognition of the species must rest upon the illustration in Reeve’s Iconica. With this, there is no doubt that B. Grayi, Reeve (fig. 65), is identical. The babylonic spire, strong sutural band of enamel, and distant revolving incised lines distinguish this species. B. sEMIPLICATA, Gray.. PI. 5, fig. 66. Whitish or yellowish, sometimes encircled by two broad, faint, brown bands. Length, 1°25—-1°5 inches. Habitat unknown. This has very much the form of the preceding species, . but the revolving incised lines are absent, and instead, the spire, and frequently the upper portion of the body whorl are longitudinally plicate. B. pigirAuis, Meuschen. PI. 5, figs. 67-69, 72. Cream-color to yellowish white, sometimes darker around the suture; orange-yellow within the aperture. Smooth, with obsolete spiral impressed lines near the base. In very large individuals the whorls are somewhat plicately wrinkled next the suture. Length, 1°5-2°5 inches. South Africa. B. rhodostoma, Gray (fig. 69), is somewhat stouter than the typical form, and B. semiusta, Reeve (fig. 68), is a mere color variety. Var. NATALENSIS, Krauss. Whorls shortly plicate at the suture. The figure (fig. 72) represents a young specimen, but this’ plicate condition persists, frequently, in the adults. I have one before me, measuring 2°5 inches. BUCCINANOPS. 13 B. Persica, E. A. Smith. | Pl. 5, fig. 70. Greyish, or lavender-color; spirally sulcate, somewhat gran- ulous next below the suture. Length, 1 inch. Bushire, Persian Gulf. ’ B. suncata, Reeve. PI. 5, fig. 71. , Lavender or lead-color, rather solid; whorls closely, concen- trically grooved. Habitat unknown. B. SEMIFLAMMEA, Reeve. PI. 5, fig. 75. Yellowish white, lower half of whorls with longitudinal chest- nut flames. Length, 1°25 inches. Cape of Good Hope. Subgenus Buccinanops, d’Orb. Embraces three species from the Southern parts of the Coast of South America. They are of rude growth, usually with a flattened shoulder below the sutures. B. cocuuipium, Kiener. PI. 5, fig. 73; Pl. 6, figs. 76-81. Yellowish white, sometimes with two obscure bands of longi- tudinally disposed chestnut-brown flames; whorls sometimes decidedly shouldered, and the shoulder defined by a somewhat corded ridge. Length, 1°5-3 inches. Brazil to Patagonia ; on the Pacific Coast, north to Peru. I do not agree with Deshayes and Reeve that Kiener’s species is different from that of Chemnitz, and therefore I do not adopt Deshayes’ name B. gradata: still, as Chemnitz was not a binom- inal writer I cannot cite him as authority for the species. The fact is that B. cochlidium is of rude, frequently distorted growth, and a collection of specimens exhibits many forms. The figure of cochlidvum given by Reeve, as exhibiting the type of the species is but slightly shouldered, and large as it is, is not adult (fig. 76); Kiener’s figure is also given (fig. 73). B. gradata, Desh., is represented by figure 77, from Reeve’s Iconica, B. _Lamarckii, Kiener (fig. 78), is another form which is scarcely shouldered, and other intermediate forms are shown in B. Pay- tense, Val. (fig. 79), and B. squalida, King (fig. 80). A remark- ably distorted shell, called by Gmelin Buc. labyrinthum (fig. 81), very probably belongs here. 14 PSEUDOSTROMBUS. B. ANNULATA, Lam. PI. 5, fig. 74. Yellowish white, columella white. Length, 1°5 inches. Narrower than the preceding species, and covered with revolving strie; yet it may be only a variety of it. B. ARMATA, Gray. PI. 6, figs. 82, 83. Yellowish white, with two broad, faint, chestnut bands. Length, 1-2 inches. Rio Negro, Patagonia. This species is considered by d’Orbigny merely a spinose variety of B. cochlidium. Subgenus Pseudostrombus, Klein. Leiodomus Swainson, cannot be distinguished as a subgenus, the distinctive characters gradually merging in those of Pseudo- strombus. B. TURRITA, Gray. PI. 6, fig. 84. Shell smooth, very finely plaited at the sutures; white, some- times obscurely brown-flamed on the lower part of the body whorl. Length, 1°25-1°5 inches. Habitat unknown. Very like the next species, but is somewhat longer and narrower, with more convex whorls; the plications shorter, only occupying a small portion of even the spiral whorls, fainter, not decussated by revolving strive. B. MELANOIDES, Desh. PI. 6, figs. 85, 86. Upper whorls crossed by well-marked plications, body whorl sometimes only plicate on the upper part; revolving strive decussate the plications of the spire. Color, yellowish white, sometimes with a chocolate-colored narrow band near the sutures and a broader one at the base, or whole surface clouded or covered with chocolate. Length, 11:25 inches. Cochin China ; Mozambique. B. Mezambicensis, EK. A. Smith (fig. 86), is deseribed from a well-grown specimen of the dark-colored variety. B. GRANULOSA, Lam. PI. 6, fig. 91. Chestnut or chocolate, sometimes obscurely banded on the periphery, with a double row of bead-like nodules revolving below the suture. Length, 1 inch. Gabon Coast, W. Africa. PSEUDOSTROMBUS. 15 Kiener, who figures this species as Buce. vittatum, Linn., con- founds with it B. melanoides, a shell from the opposite coast of Africa, and quite distinct, judging from the specimens before me. Lamarck considered it a Terebra, a genus to which this shell is closely assimilated by its usually very narrow form, polished surface and sculpture. B. porira, Lam. PI. 6, figs. 88, 89. Cream-color, yellowish brown or livid olive, with frequently a very indistinct darker band near the suture; whorls of the apex plicate, rest smooth and polished. - Leneth, 1-1°25 inches. Senegal. B. vitrea, Reeve (fig. 89), is synonymous. B. Kurracuensis, Angas. PI. 6, fig. 90. White, tinged with rose-color on the upper whorls. Length, 1°75 inches. Kurracht, Scinde, N. W. India. Only thé type specimen known. B. virrata, Linn. PI. 6, figs. 87, 92. Yellowish or lilac-white, or bluish or brown; sometimes the spire is clouded bluish whilst the rest of the shell is light colored. Sutural plications defined by an incised revolving line and some- times cut in two by another line. Length, 1°5-1-°75 inches. Ceylon ; Zanzibar. B. livida, Reeve (fig. 92), is only one of the many slight vari- ations which can be readily traced to the typical form. This species occasionally develops a varix on the outer lip, and speci- mens are before me in which a former varix is persistent. B. TAHEITENSIS, Gmelin. PI. 6, fig. 93. Spirally ridged, ridges finely granose, two or three ridges next the suture more distant than the rest; yellowish, maculate with orange-brown, interior of aperture brown stained. Length, 1°75 inches. Tahetti. A very rare species, and the only one having its pattern of sculpture. The figure in Chemnitz is evidently poorly drawn, and there can be no doubt that the British Museum specimen, figured by Reeve, is a better representation of the species, as it more nearly approaches a specimen now before me. 16 ADINUS. B. BELANGERTI, Kiener. PI. 6, figs. 94, 95. Whorls smooth, polished, with distant revolving grooves which are most apparent at the suture, and base of the body whorl; yellowish, with waved longitudinal faint chestnut lines. Leneth, -9-1-4 inches. Aracan, Ceylon. B. polita, Desh. (fig. 95), is this species, figured from a faded specimen. B. pituta, Krauss. PI. 6, figs. 96, 97. Whorls with revolving strie; whitish, lower part of body whorl longitudinally flamed with chestnut-brown; columella truncate at base. Length, 1 inch. Nutal, So. Africa. Painted like B. semiflammea, Reeve, but immediately disting- uished from that species by its narrow Yerebra-like form and truncate columella. This last character suggests the succeeding species which, however, is peculiar in having a thiekened lip, minutely dentate within. It is possible that they are identical, and that B. diluta has a thin, unarmed lip because the specimens are not adult. Von Martens has described a var. mediolexvis (fig. 97), in which the revolving grooves do not occur on the middle of the body whorl—a character of no importance. Subgenus Adinus, H. and A. Adams. B. truNcATA, Reeve. PI. 6, fig. 98. Yellowish white; whorls striated above and at base. Length, 1:25-1°5 inches. Habitat unknown. The characters of this species are those of the subgenus, It is probably So. African. See remarks under preceding species. Unidentified and Doubtful Species. B. ELONGATULA, Anton. Habitat unknown. B. tcrerica, Solander. H. and A. Adams’ Genera. B. osseuM, Menke. The type specimen is lost. B. veLATA, Gould This is undoubtedly a Nassa gaudiosa. B. TamsrAna, Dunker. Guinea, W. Africa. B. Cumrinatana, Dunker Habitat unknown. B. ELEGANS, Dunker. Habditet walls B. LyMNEANA, A. Ad. = Volutharpa. NASSA. 17 A H. and A. Adams in their ‘Genera of Recent Mollusea” have ‘enumerated 210 species of Nassa; Reeve’s Monograph in the “Conchologia Iconica” contains 182 accepted species and 13 synonyms, = 195 names in all. The present monograph includes 595 specific names, of which 131 only are accepted as good species, 364 are relegated to the synonymy of these, and 100 are undetermined for want of illustrations or specimens. ‘The dis- tribution of the genus is world-wide, except that no specimens exist in the i¢gy seas near the poles—where they appear to be replaced by the Buccinums. They occur principally in the waters of tropical and subtropical latitudes. The fossil species are few in number, commencing with the Eocene formation. For some of the American fossils Mr.'T. A. Conrad has proposed distinct generic names, but their separation from Nassa is scarcely advisable. The animal of Nassa has a broad head, and a foot quadrately expanded in front, with the corners often pointed, whilst behind it bifurcates and is prolonged frequently into two subulate tails. The operculum is usually serrate on the margin but is sometimes plain. The Nassz are very active, and not at all shy when kept in confinement. They may be occasionally seen floating with the foot upwards. They are predaceous, feeding on other mol- lusks, the shells of which they bore. I have frequently seen the shells of the American species themselves bored, the hole being of such a size as to suggest cannibalism. Perhaps the avenger of their misdeeds is a beautiful and very active hermit crab which disports itself in the Nassa’s shell, immense multitudes being seen at low tide in the water near the shore line. Whether begged, borrowed, stolen, or lawfully captured by the red right claw, it is certain that, at Atlantic City, New Jersey, the hermit inhabits a vast majority of the specimens of Nassa occurring to the collector. Although most of the species are littoral, a few have been collected at considerable depths; the undescribed N. brychia, Watson, was dredged at 620 fathoms by the “ Challenger Expedition.” Sdéme of them have been observed to spring up and throw themselves over on being suddenly disturbed. Usually they glide along the surface of the mud, leaving a track indicating their line of march, at the end of which is a small Genus NASSA, Lam. 2 o 18 NASSA. round pellet; under this the creature conceals itself. The fry twist and twirl about by means of their ciliated lobes. 4. mutabilis is an article of food in Italy. The generic name is that of a narrow-necked wicker basket used for catching fish, and in such a basket, lobster pots, ete., the Nassa itself is frequently caught, attracted thither by odors savory. Nassa reticulata is said to be very destructive in the oyster pares of Arcachon (8. of France). It is so numerous that a single tide has yielded 14,600 specimens within a space of 40 French hectares (= about 100 acres). The adult Nassa will hore through the shell of an oyster three years old, within eight hours; but the young sheils are far more destructive because they select the tender shells of the very young oysters, some- times piercing fifteen or twenty in succession before their hunger is satisfied. An oyster a month old is destroyed in a half hour.* One of the best students of the genus Nassa is undoubtedly Mr. F. P. Marrat, of the Liverpool Museum.¢ Imbued with extreme development views he has, unfortunately, adopted the principle in his scientific work that, the variations of species being illimitable—species in fact, as usually defined, being non- existant, the naturalist may apply a specific name for each modification of form, sculpture or coloration; a principle the absurdity of which must be apparent when it is considered that, no two shells being exactly alike, it will admit of the description of every individual specimen as a “new form.’ Mr. Marrat has, however, fully demonstrated the insufliciency of distinctions based on sculpture in a number of species of the genus; a result most confusing to the systematist,and which leaves the validity of many forms described from single or few specimens very questionable. Iam tempted to make some extracts from Mr. Marrat’s latest paper,{ the subject of variation being sufticiently important in a general sense to justify me in devoting a few lines to its illustration in this particular genus. * Soubeiran, Bull. Soc. d’ Acclimatation, 2 Ser., iii, 3, 1866. + “On the variation of sculpture exhibited in the shells of the genus Nassa.”? ‘‘On forty proposed new forms in the genus Wussa,’’ ete. t “On the Varieties of the Shells belonging to the genus Nassa.”’ NASSA. 19 “The study of varieties in the genus Nassa,” says Mr. Marrat, “has achieved one great object—it has taught us the whole details of the plan on which the external ornamentation of shells has been elaborated. The whole of the variation, from the smooth shell to the most elaborately-sculptured examples, is plainly to be seen as effected through almost imperceptible gradations. , “Variation through the whole kingdom of Nature is the rule and not the exception. It is the prejudice exhibited by Scientists against so much that is clear and distinct, that creates the con- fusion. If studied as it exists, the whole group is manifestly developed, step by step, and we see the wisdom, power and beneficence of the Maker. “The greater part of the works on Natural History are written in the closets of the authors, who both theorise and copy to a large extent; but, unfortunately, they copy errors as well as facts. “The study of variation has opened up a subject so vast in its dimensions that the mind almost shrinks from the task of estimating it. In every direction variation extends, in every way variation seems to ramify, until we gaze and wonder if there be any end. “Tnstead of 200 species, at least 2000 varieties are before me, and the end appears nearly as far off as ever. Taking a careful survey of the shells under consideration, and noting more par- ticularly the common forms and the changes presented by them, we are enabled to form an estimate of the enormous number likely to be met with, if we persevere in our work of collecting varieties. “ Species are and have been made by men in their ignorance. Had they known the alliances, it would have been impossible for them to have committed such mistakes as are to be found in conchological books. Species have been and still are the ultimatum of scientists. It appears to me that they have an instinctive horror of the nameless. Lamarck described the Nassa subspinosa from shells that were subspinous, not then knowing that there were carinated, costated, muricated, and smooth varieties of it. At least six good (?) species have emerged from the varieties of Lamarck’s shei: WN. lyrata, 20 NASSA. Marrat, is the lyrate form; N. tricarinata, Lam., is the carinated form; N. sculpta, Marrat, is another; WN. sistroides, Nevill, N. trinodosa, Smith, and N. corticata, A. Ad. Another variety occurs, showing a close affinity with the N. muricata, Quoy and Gaim., and the shell figured in Reeve’s Conchologia Iconica as the N. vibex, Say, isaspiny form. Some of the shells from Ceylon are very closely connected with varieties of the WN. Grunerti, Dunker, and others with smoother ribs to the N. Jack- soniana, Quoy and Gaim. “We may name these shells and describe them as distinet, but they will not be so after we have finished; on the contrary, we may adopt another plan and name them varieties, but the same objection continues; the variety we have named as coming from any locality will be found to differ from the shells brought up from the same ground by the next haul of the dredge. It isa very disagreeable task to be compelled to state that the starting point of the systematist, upon which the whole fabric is built up, is wrong, and the whole of the deductions drawn from this source are erroneous; nevertheless I am compelled to utter that which I believe to be strictly and unquestionably true. I can- not expect that conchologists who are totally unacquainted with the materials upon which I have based my deductions, will coincide with my views. If they had obtained a knowledge of the whole of the figured or described species of Nassa, they could not by this plan follow the intricate passages revealed by the study of variation. It is not by an intimate knowledge of the described species that these facts are elicited, but it depends upon a knowledge of the innumerable intermediate forms which diverge from them in every direction as to how these deductions are to be drawn. “In a long’series of forms, commencing with shells represent- ing the largest specimens in the genus, these can be traced with unerring certainty into others, forming the smallest examples known to exist; again, the broadest varieties can just as easily be connected with others that are the narrowest examples in the group; and every grade of difference throughout the long lines of progressive variation is distinctly seen. In the case of the shells having smooth forms, such as N. glans, Linn., the varieties may not be all smooth specimens, but they may vary into costate NASSA. | and even cancellated examples. Again, instead of there being a uniform thickness observable, one set will be almost transparent, _or thin and hyaline, and another thick and quite opaque. The sculpturing is in many cases confined to the upper whorls, but we find shells in which the pattern is commenced on the top, gradually spreading in successive development until it covers the whole shell; in one case it may form smooth unsculptured ribs, or in another it may diverge into any of the forms of sculpture we meet with in other groups of shells. The tip of the spire may be of the same color as the remaining portion of the shell, or it may vary into almost every shade of pink, rufous, brown, purple, or almost black. “From these observations taken from the shells, and not intended to support or illustrate any theory, it is very easy to see that instead of a fixedness in the characters used for the determination of species, exactly the opposite appears to be the case; the specimens presenting such an amount of variation in every direction that it becomes absolutely impossible to aflix any set of characters to them that will lead to their future recognition. “The greater part of the shells figured and described as new species have for their recommendation to our notice a single specimen, and that often in bad condition. Men are so anxious to have their names appended to something new that every other consideration is overlooked by them. They cannot wait until sufficient evidence is produced: either to confirm their opinions or show them that the characters they had given were incorrect, but down it goes on to paper, and there it remains.” What a commentary on this and preceding paragraphs is the printing of numerous new names and descriptions in the very pamphlet from which these brave extracts are made! These new species, alas! are not even figured, no dimensions are given, and in many cases no locality. The descriptions are prefaced by the remark—“‘ What are the shells described in the following pages ?_My answer is, I do not know. The amount of knowl- edge is confined to the single specimens (!) in most instances and to three or four at most in any case. At present these shells appear to me to be distinct, simply because of my igno- rance of all their alliances, but that this should be the real 99 NASSA. state of the case is exceedingly improbable if not absolutely impossible.” Mr. Marrat’s dilemma is that, whilst disbelieving in species, he cannot pursue his work without naming and describing species. It would be impossible to give a full descriptive portraiture of an object every time it is referred to, in order that the writer’s conception of it and that of the reader shall agree; therefore we adopt a conventional system—the binomial nomenclature to recall certain characters by the use of two names. I think, however,. that it is a logical deduction from the views expressed by Mr. Marrat that his species should not possess such salient characters as those proposed by authors who believe more or less in the doctrine of the persistence of form: if the latter species do not present very strong claims for recognition, the former may be supposed to present no claims whatever,—unless we agree that each individual specimen in the genus shall receive a distinct specific name. If there be only one species in the genus Nassa, as opined by Mr. Marrat, science still requires names for those groups which normally present recognizable distinctive char- arcters; without a nomenclature and a system, however arbitrary and unnatural, the publication of the results of scientific research would be impossible. The doctrine of unalterable uniformity in specifie characters is overthrown, but a wise conservatism will, let us hope, cause conchologists to refrain from naming and describing every individual specimen: at least, gentlemen, do not overwhelm our ancient and tottering barriers with your logical deluge, until we, who have so carefully erected and guarded them, shall have retired from conchological pursuits. Apres nous le déluge, if you please! Typical Species. N. muraAsitis, Linn. PI. 7, figs. 1-3. Light brown, with somewhat undulated longitudinal darker markings, generally confluent into a darker interrupted band at the sutures. Length, 1—-1°25 inches. Mediterranean Sea, 4to 10 fathoms; W. Coast of Africa ; Canary Isles, Fossil in the miocene of S. Hxrope. Upon the embryology of this species see Bobretsky, in Archiv fiir Mikros. Anat., xiii, 97. NASSA. 93 N. Pfeiffer, Phil. (Pl. 11, fig. 144), has been referred to this species as a variety by Marrat and others; [| do not think, how- ever, that it can be placed in the same group at all, as all its affinities are with Zeusxis. N. TENuIS, E. A. Smith. Pl. 7, figs. 4, 5. Yellowish white, mottled with yellowish brown, darker at the ‘suture. Length, 20 mill. Jupan ; China. This species was described by Lischke as N. Japonica, after- wards changed to WN. balteata, on account of the previous use of the first name by Mr. A. Adams. WN. balteata being preoccupied by Pease, Mr. E. A. Smith has referred the species to his N. tenuis, which was originally described without reference to these relationships. Mr. Smith also refers the WN. Japonica, Adams, here, doubtfully, the type having disappeared from the Cuming- ian collection. I fear I must add to this confusion by doubting the identity of Mr. Smith’s species with balfeata, Lischke, _ although it appears to correspond well with Adams’ description of Japonica. N. sufflata, Gould (not figured), appears from the description to be identical. The species is very closely allied to N. mutabilis, L. N. pa&vieata, Marrat. PI. 7, fig. 6. Yellowish white, with darker strigations, which tend to mass into revolving bands in some specimens. The suture is some- times noduled. Length, ‘75 inch. China. The spire is. more elevated, the shell more solid than the last species; the coloration and polished surface allies it to the mutabilis group. N. cornonata, Brug. PI. 7, figs 7, 8. White, olive or chestnut; with usually a white median zone on the dark varieties or a darker zone on the light colored specimens. Length, 1-1-2 inches. Madagascar, Java, Philippines, ete. N. Bronni, Phil. (fig. 8), is not distinct. 24 ARCULARIA. N. ARCULARIA, Linn. PI. 4, figs. 9, 10. Light colored with dark zone,or dark with a light zone; shoulder noduled, with usually a rib-like fold arising from each nodule. Length, 1—-1:25 inches. Philippines, Viti Isles. N. laticostata, Marrat (not figured), is probably this species, not adult. N. suncirera, A. Ad. PI. 7, fig. 11. Ash-color, banded with white, longitudinally subplicated, transversely ridged. Length, 1°25 inches. : Algoa Bay. Probably only a variety of N. arcularia: the single specimen known is abnormal in its appearance, and it is therefore not easy to assign to it a definite place in the synonymy. N.. puna, Linn. Pi. 7, figs. 12-14: The plications are much closer and more numerous than in N. arcularia; an incised revolving line separates the shoulder extremity of these ribs, forming a row of nodules; additional incised lines cross the entire surface, but are most conspicuous on the spire, and lower portion of the body whorl. Length, 1-1°35 inches. Red Sea, Java, Philippines. N Rumphii, Hombr. and Jacq. (fig. 13),is synonymous. That N. pulia is itself identical with N. arcularia, is demonstrable from the series of specimens before me. In N. plicata, Bolt., the longitudinal ribs are less and the revolving lines more prominent; another similar variation of sculpture has received the name N. Deshayesii, Homb. and Jacq. (fig. 14). Subgenus Arcularia, Link. N. aipBposuLA, Linn. PI. 7, figs. 15-17. Light yellowish or ash-color, banded, flecked, or blotched with white or darker shades; edge of callus frequently defined on both sides of the back by an orange-colored line; callus whitish ; within the aperture yellowish. Length, °75 inch. Mediterranean Sea. ARCULARIA. 25 N. circumcincta, A. Ad. (fig. 17), is founded on specimens showing the orange-bordered callus. It was erroneously reported from the Red Sea, but has been found at Alexandria and on the Syrian Coast. N. Krausstana, Dunker. PI. 7, figs. 18, 19. Yellowish brown, indistinctly dark banded; callus yellowish or orange. Length, -4—5 inch. South Africa. _N. orbiculata, A. Ad. (fig. 19), is identical. N. Tuersites, Brug. PI. 7, figs. 20-23. Ash, yellowish or brown, sometimes mottled, with usually a light central band. Ribs usually obsolete on the mouth side of the dorsal hump. Length, -6—85 inch. ‘ Indian Ocein, Hong Kong, Manilla, Australia. N. bimaculosa, A. Ad. (fig. 22), represents a stumpy specimen of this species. It was described as from the Philippine Islands, and Mr. EK. A. Smith reports it from Andaman Islands, “ sand- banks, at low tide; very active animal.” N. dorsuosa, A. Ad. (fig. 23), from Philippines, is evidently a monstrosity ; besides, .the shell looks as if it had been roasted: it is probably a synonym. N. veprosprra, A. Ad. PI. 7, figs. 24-28. Yellowish ash-color, longitudinally rather closely plicated ; callus yellowish, wide spread. Length, 75 inch. Ilo Ilo, Isle of Panay, Philippines (on mud banks, at low water, Cuming); Jupan; Ascension Isl. (Pease'. This may be considered on the one hand as a less-developed form of N. Thersites, on the other as connected with N. foveolata, N. livescens, etc., in which the sculpture and general appearance are similar, but the callus is not spreading. I unite with it N. gracilis, Pease (fig. 25), N. bellula, A. Ad. (fig. 26), N. labida, Reeve (fig.27),and N. Persica, Martens (fig.28). N. Deshayesiana, Issel, has been considered the equivalent of N. Persica, von Martens, by several excellent conchologists: very probably it is so, but it is tuberculate, shouldered, without spreading callus, and typically is no closer to N. Persica than are most of the nodulous species. 4 26 ARCULARTA. M. Jonast, Dunker. PI. 8, figs. 29-32. Whitish, yellowish or ash-color, usually chestnut at the suture and base, with sometimes a central chestnut band. Spire and upper portion of body whorl ribbed, sometimes cut into nodules helow the suture. Length, -4—6 inch. Port Jackson, Australia. N. Burchardi, Dunker (fig. 30), is in every respect typical. N. labecula, A. Ad. (fig. 31), and WN. nana, A. Ad. (fig. 32), are evidently the same species. N. canLosa, A. Ad. PI. 8, figs. 33, 34. Very broadly gibbous when adult, with wide-spreading, thick margined callus; ribs small, distant, sometimes cancellated and nodulous ; white, three banded with chestnut or suffused with with olive. Length, -4—5 inch. Phil'ppines, in sandy mud at’seven fathoms ; Indian Ocean. This may be only a variety of the preceding species, from which it is distinguished principally by form and sculpture. WN. callospira, A. Ad. (fig. 34°, is synonymous. N. cANCELLATA, A. Ad. PI. 8, fig. 35. Light brown, maculated with darker brown. Length, °6 inch. Philippines. The type is said to be rather thin and semitransparent. N. MANGELIOIDES, Reeve. PI. 8, fig. 36. Solid, dark ash-color; whorls tuberculated at the upper part, tubercles here and there prolonged into ribs, interstices cancel- lated. Leneth, -5 inch. Port Jackson, Australia (Angas). May be only a more solid growth of N. cancellata. N. aroposa, Quoy. PI. 8, figs. 37, 38. Longitudinally finely plicated, crossed by revolving striz ; yellowish white, tinged or nearly covered with chocolate, with frequently a white central band. Length, ‘5-65 inch. New Ireland, Viti Isles. N. clathrata, Kiener (fig. 38\, is the same. N. GRANIFERA, Kiener. PI. 8, figs. 39-41. White or yellowish, tuberculate. Length, ‘6-9 inch. Philippines to Central Polynesia ; Isle of Bourbon. NAYTIA, ALECTRION. 27 Mr. Marrat considers his N. nodulosa probably a deep-water form of N. granifera: it is not figured. N. obliqua, Hombr. and Jacq. (fig. 40), N. obliqua, Pease (unfigured), and N. onerata, Desh. (fig. 41) are synonyms. Subgenus Naytia. Il. and A. Adams, N. GLABRATA, Sowb. PI. 8, figs. 42, 43. Light fawn-color, highly polished, with sometimes, traces of ribs at the sutures. Length, ‘5--6 inch. W. Coast of Africa. Described doubtfully as a Strombus. N. obliqua, Kiener (fig. 43), is a Synonym. N. RANA, Lam. PI. 8, fig. 44. Yellowish white, brown spotted at the sutures, and with inter- rupted revolving brown lines. Length, ‘4 inch. Mediterranean Sea. Subgenus Alectrion, Monrf. N. euans, Linn. PI. 8, figs. 45-49, 52-54. Yellowish white, clouded with yellowish brown, encircled with equidistant, narrow, chestnut-colored lines. Length, 1°5—2 inches. Japan, Philippines, Australia. This is the largest species in the genus: it either varies much, however, in size and proportion, or else the following forms should be considered distinct. As they all possess the revolv- ing dark-colored lines, I prefer to consider them as simple dwarf varieties. Var. LATA, Tryon. Fig. 46. Broadly ovate, approaching N. mutabilis, L. in form. Length, 22 mill. Three specimens, without locality, in the Museum of the Philadelphia Academy. Var. ELEGANS, Kiener. Figs. 47-49. Whorls inconspicuously shouldered beneath the sutures. Besides the revolving brown lines the surface is clouded or striped longitudinally, and revolving series of quadrangular spots frequently occur upon the shoulder and middle of the whorl. Length, 22-27 mill. So. Australia. 28 ALECTRION. A smaller, more gracefully formed shell than the type, and typically sufliciently distinct, but varies much. Kiener’s figure is a poor one (fig. 47), and that which Reeve has given, as well as his description, refers to a N. tenia, Gmel. The following are synonyms: JN. rufula, Reeve (fig. 48), and N. spirata, A. Ad. (fig. 49). Var. suTURALIS, Lam. Figs. 52-54. Shoulder coronated by a row of tubercles. Length, 1—-1°5 inches. Philippines, Australia, New Caledonia. Fig. 54 represents the typical form, whilst fig. 53 shows a variety with the tubercles almost obsolete, passing into var. elegans. N. intermedia, Dunker (fig. 52) is an equivalent form, and N. bucculenta, Marrat, an unfigured species, may also be placed here. N. Herta, Kiener. Pi. 8, figs. 50, 51, 55-59. Light yellowish or orange-brown, with usually a pale central band. Length, 1 inch. ‘Philippines, Australia, Polynesia, Indian Ocean. The undoubted synonyms of this species are NV. Vitiensis, Hombr. et Jaeq. (fig. 57), N. Stoliczkana, Nevill (fig. 58), NV. costata, A. Ad. (fig. 50) and WV. crenulata, Reeve, not Brug. (fig. 56). iW. erenulata, Brug. is not to be identified positively, but looks more like NV. arcularia than the present species. WN. hirta probably runs into the next species, NV. monile. N. nodifera, Powis (fig. 55), is not a satisfactorily determined form; if the figure which I copy from Reeve is correct, it appears to be ¢ very broad, short, large specimen of J. hirta, connecting with N. pulla, Linn. The localities of NW. nodifera, “ Panama and Galapagos,” are almost certainly incorrect. N. bifaria, Baird (fig. 59) is, I think, a stumpy variety. N. MONILE, Kiener. PI. 9, figs. 60-68. Yellowish or ash color, with a rather broad darker central band, and sometimes narrower ones above and below it. Surface beautifully polished, ribs more flexuous than in WN. hirta; a double row of nodules below the suture, caused by an impressed line on the sloping shoulder. Length, 1 inch. Philippines, Australia, Central Polynesia. ALECTRION. 29 This species is, typically, readily distinguished from J. hirta, but appears to approach the latter through varieties. The oldest name given to it is possibly N. hepatica, Mont., who fig- ured a similar species in error as British, but it is well known as monile, and no useful purpose will be subserved in changing its name. N. lachrymosa, Reeve (fig. 62) and N. pauperata, Quoy = N. bullata, Marr. (fig. 61), are synonyms, and N. Jacksoniana, Quoy (figs. 63, 64) is a dwarf race, from Australia—a well- marked yariety. N. mucronata, A. Ad. (fig. 67), is a variety in which the ribs are partially separated into granules, and N. dis- torta, A. Ad. (fig. 68), is a monstrosity, apparently of this species. J. corticata, A. Ad. (fig. 66), appears to — var. Jack- soniana, as does also N. acuticostata, Montr. (fig. 65), and N. Tasmanica, Woods (unfigured). N. opesa, G. and H. Nevill. Shell thick, shining; brown indistinctly and minutely mottled with white, irregularly stained near the suture with a darker shade of brown; two rows of more or less granulose ridges immediately beneath the suture, columella with a moderately large, white callosity, slightly rugose, aperture ridged near its margin. Length, 22 mill. Kutch. Var. Crytonica, G. and H. Nevill. More acuminate, less globose, suture more distinct; longi- tudinal ribs on the antepenultimate whorl more or less obsolete. Length, 19 mill. Ceylon and Penang. Has the coloration but not the fragility of V. mutabilis, differ- ing also in being sculptured. Thickness, sculpture, and particu- larly the double row of granules beneath the suture indicate intimate relationship with WV. monile. N. scataris, A. Ad. PI. 9, figs. 69, 70. Pale yellowish, obscurely banded with reddish brown. Length, 1-3 inches. Isle of Corrigidor, Philippines, in coarse sand at seven fathoms.—Cuming. Appears to partake of the characters of N. monile and N. papillosa. N.crenulata, Kiener, not Brug. (fig. 70), and N. cren- ellifera, A. Ad. (fig. 75), seem to be the same species. 9 50 ZEUXIS. N. Srquigorensis, A. Ad. Pl. 9; digs. 72-73; Yellowish white, three banded with chestnut. Length, ‘7-1 inch. Indian Ocean, Philippines, Central Polynesia, A narrower form than any of the preceding, and connecting undoubtedly with N. sealaris, A. Ad. Except the one below the coronal of tubercles around the suture, the revolving lines are only apparent towards the base of the shell. N. calata, A. Ad. (fig. 73) appears to be the same. N. PAPILLOSA, Linn. PI. 9, figs. 74, 71. Whitish, more or less blotched with yellowish brown, spire usually pink tipped. Length, 1°25—2°25 inches. Philippine Islands, Central Polynesia. N seminodusa, A. Ad. (fig. 71), may connect this form with the last, and through it, with N. monale. Subgenus Zeuxis, H. and A. Ad. With this group is united Velasco, H. and A. Adams, the characters by which those authors distinguish them being, in some cases at least, dependent upon the age of the specimens ; juvenile forms belonging to Telasco, adult to Zeuxis. To be sure, none of the subgeneric groups have suflicient claims to distinctness, but in this case I am utterly unable to distinguish them. Messrs. Adams give as characters of Telasco, “ inner lip spreading, outer lip simple, acute;” but many well-grown species have the inner lip with well-defined margin to the callus, and all of them, when adult, have a thickened or externally variced outer lip, dentate within. Zeumis is said to be “ covered with an epidermis,” but in most of the species referred to it, there is certainly no epidermis. For N. elegans, Reeve, Messrs. Adams make a subgenus Zaphon, but as I consider that shell a synonym of N. tenia, Gmel., the type of Zeuris, of course Zaphon becomes a synonym. N. r#niA, Gmel. Pl. 9, figs. 76-82. Chocolate or chestnut brown, with usually a central, narrow, light band ; spire whorls ribbed, body whorl varying from smooth to plicate-ribbed. Length, 1-25-1°75 inches. Ceylon, Singapore, Australia, Polynesia. ZEUXIS. 31 The habitat ‘‘ West Indies,” given by Reeve, is erroneous, 4s is also that of “ Chili,” in Kiener. A goodly number of species may be referred to this form with some confidence: ‘They are N. plicata, Pease (preoccupied) — N. approximata, Pse., N. Jusca, Hombr. et Jacq. (fig. 78), N. mitralis, A. Ad. (fig. 79), N. badia, A. Ad. (fig. 81), N. cinnamomea, A. Ad. (fig. 80). In N. elegans, Reeve, not Kiener (fig. 82), the style of painting varies considerably from the type, but I have before me a similarly painted specimen, which is undoubtedly a N. tenia. N. CANALICULATA, Lam. PI. 9, figs. 83-86. Ash-olive, sometimes faintly two banded with chestnut ; sutures channeled and frequently crenulate; upper whorls closely ribbed, ribs sometimes apparent on the back of the body whorl. Length, 1:1-1°5 inches. Philippine Islands, Polynesia. N. levis (Chemn.), H. and A. Adams (fig. 86) is a synonym. N. sronipa, A. Adams. PI. 10, fig. 87. Bluish-ash, sparingly blotched or banded with yellow and brown. Length, 1:25 inches. Habitat unknown. Described from a single specimen, which is evidently of ab- normal growth. N. uNIcoLORATA, Kiener. Pl. 10, figs. 88, 89, 90. Livid ash-color, sometimes stained or banded with brown ; aperture chocolate-colored within. Length, 1-1-3 inches. Moluccas, Australia, New Zealand. A Bullia-like species, normally very distinct, yet undoubtedly closely connected by transition forms with N. canaliculata and N. tenia. N. unicolor, Hombr. and Jacq., is identical; the figure which I give (fig. 89) probably represents a similar shell to that which Gmelin called N. trifasciata. N. rutilans, Reeve (fig. 90), and probably WV. glauca, Dunker, an unfigured species, belong here. N. vARiciFERA, A. Adams. PI. 10, fig. 91. Whitish, with two brown bands; whorls crossed occasionally by a varix. Length, 1 inch. Japan. i) i ZEUXIS., - Has the appearance of an Epidromus (Tritonide), but wants the produced canal of that group. The production of true varices is certainly not a characteristic of the genus Nassa, yet the species has been collected often.enough to show that it is not an abnormal condition: it is strange that Messrs. Adams did not make a new genus for it. N. Cuvieri, Payr. Pl. 10, figs. 92-97. Yellowish white, usually mottled with chestnut, with a darker line beneath the suture, and frequently, a chestnut central band. Length, -4—75 inch. Mediterranean Sea; Allantie Coast of Spain, Portugal ; Madeira ; Canary Isles. This pretty little species is the victim of an immense syn- onymy, and of much uncertainty as to nomenclature. It is frequently referred to as N. variabilis, Phil., and as N. Ferussaci, Payr.; less frequently as N. unifasciata, Lam., N. nitidula, Linn., NV. costulata, Ren., and a dozen other names. As regards the Linnean name, the specimen bearing it in the Linnean col- lection has been identified with this species, but the only figure cited in the description is that of a Columbella. The descrip- tion itself will suit almost anything. NN. Maderensis, Reeve (fiz. 97), differs only in the numerous revolving, interrupted, chestnut lines, which, faintly seen in many Mediterranean speci- mens, here become more prominent. N. sEMIPLICATA, A. Ad. PI. 10, fig. 98. Yellowish, encircled by two chocolate bands. Length, 22 mill. Chusan. N..TERETIUSCULA, A. Ad., PI. 10, fig. 99. Yellowish or ash-olive, with a narrow red revolving line. Length, °6 inch. Eastern Seas. The locality is very indefinite, and the figure, notwithstanding the red line, is very suggestive of N. ewilis. N. EXILIS, Powis. Pl. 10, figs. 100-102. Ash-olive, with a central white band. Length, :4—-7 inch. Panama, Viti Isles, Solomon Is., Peru. ZEUXIS. 38 The synonyms are N. Panamensis, C. B. Ad., N. Fontainei, d’Orb. (fig. 102), and N. mesta, Hinds (fig. 101). I give the locality Viti Islands on the authority of Mr. A. Garrett, and Solomon Is. on that of Mr. John Brazier, who personally col- lected it at those places. N. Fontainei, VOrb. (fig. 102), from the Coast of Peru, is larger than the Panama specimens of exilis, yet immature; of its identity there can be no doubt; form, sculpture and colora- tion being the same. N. coMPLANATA, Powis. PI. 10, figs. 105-107. Olive or ash, with a yellow band above the periphery. Ob- liquely granosely ribbed, ribs and granules frequently obsolete on middle and lower portions of the body whorl. Aperture dark within, but showing the light band. Length, °5 inch. ; W. Columbia, Panama. Proportionally wider than N. exilis, but with the same colora- tion, its form being intermediate between that species and J. tegula, Reeve. WN. scabriuscula, C. B. Ad., and N. Wilsoni, C. B. Ad. (fig. 106), are synonyms. Possibly N. gemma, Phil. (fig. 107), may also belong here, as suggested by Mr. Marrat. N. Capensk, Dunker. PI. 10, figs. 108-110. Yellowish or white, with a brown band. Length, 65 inch. / South Africa. N. pulchella, A. Ad. (fig. 110), is a variety. N. casta, Gould. PI. 10, fig. 103. Whitish, with a subsutural and a central brown band. Length, °4 inch. Pacific Islands. Evidently immature, and the figure rather inaccurate. It isa doubtful species, and is only inserted here because Gould remarks upon its resemblance to N. Cuvier. N. IsaBeLuer, d’Orb. Pl. 10, fig. 104. White, ribs evanescent on the body whorl. Animal white, active in its movements. Length, 5 mill. Rocks; San Blas, Patagonta. Probably not a Nass. 5 34 ZEUXIS. N. FOVEOLATA, Dunker. PI. 10, fig. 111. Ash-colored ; longitudinally finely ribbed, interstices cancel- lated. Length, ‘7 inch. Hab. unknown. The figure is rather wider than the usyal form of N. leptospira, and shows a narrow, defined columella-callus ; nevertheless, I strongly suspect that this is only an immature form of that species. N. pLANicosTaTA, A. Adams. PI. 10, fig. 112. Ash-colored, closely and finely flat-ribbed, ribs sometimes obsolete on the body whorl. Length, 20 mill. Payta, Peru ; under stones at low water.— Cuming. N. sparta, Marratt. Pl. 10; fig. 113. Light ash-color, fasciate with fulvous, purplish within. Length, °5 inch. W. Coast of So. America. I am not acquainted with this species. N. GAuprosa, Hinds. PI. 10, figs. 114-120; Pl. 11, figs. 121-124, 126-132. Spire usually acuminate, ribbed, sutures crenulate or smooth, body whorl generally smooth. Whitish, yellow, rufous, choco- late, with frequently distant, narrow red revolving lines and irregular broad bands; maculate or closely punctate with darker markings ; sometimes unicolored. The form varies from elongated to broad ovate, frequently constricted at the upper part of each whorl. Length, ‘75-1 inch. Straits of Malacca, Philippines, Polynesia, Sandwich Islands, Guinea Coast, W. Africa. A solid, smooth, usually gaudily painted species, varying very much in form and coloration. A large number of these variations have received specific names, but I do not find in any of them really distinctive characters. N. sertula, A. Ad. (fig. 116), and N. semisulcata, Dunker (fig. 117), have the typical coloration, and the latter possesses the distant red revolving lines, which so frequently form the groundwork of the ornamentation. In N. zonalis, A. Ad. (fig. 118), the three brown bands which are obscurely marked in N. sertula, become well colored. Another ZEUXIS. 35 modification of the banded form is N. succincta, A. Ad. (fig. 119). N. Marratii, B. A. Smith (fig. 120), is a small form in which the sutures are maculate ; the colored revolving lines are present in the specimens before me, but in the darker colored ones are much obscured by the coloration. In N. punctata, A. Ad. (fig. 121), the sutural painting is retained, but the shell is so clouded with dark chocolate-color as to obscure the other markings. WN. compta, A. Ad. (fig. 122), is similar, whilst the inkiest specimens have been called N. velata, Gould (figs. 123, 125), and N. luctu- osa, A. Ad. (fig. 126). N. lentiginosa, A. Ad. (fig. 127), has been proposed for shells allied to punctata, dark in color, with sutural crenulations and red revolving lines. N. mustelina, Gould, and N. ferruginea, Marrat, both unfigured, are also probably syn- onyms. A light -colored or nearly white variety, with the revolving brown lines and brown maculations, has been called by Gould N. lilacina (fig. 128), and by Dunker N. coturniax (fig. 129). To these may be added also N. sesarma, Marrat (fig. 130), from Whydah, Coast of Guinea, W. Africa; and N. pal- lidula, A. Ad. (fig. 131), a faded specimen from Malacca, and which equals N. micans, A. Ad. (fig. 132), a similarly faded specimen from the Philippines. N. flava, Marrat, habitat un- known, and JN. polita, Marrat, from Mauritius, both unfigured, are, judging from the descriptions, at least very closely related to N. gaudiosa. N. clandestina, A. Ad., an unfigured Japanese species, may also be placed here until a figure may perhaps fur- nish the distinctive characters which cannot be found in the description. N. prora, Dunker. PI. 11, figs. 183-142. Shell broadly ovate, very smooth and polished; spire short, conic, first finely, then distantly, undulately plicate ; body whorl narrowly round-shouldered above, sometimes obsoletely tuber- culate on the shoulder, incisely striate near the base. Color everywhere minutely flecked with brown or ash and white, with sometimes narrow brown revolving lines. Length, “6-8 inch. Philippines, Mauritius, Australia, Central Polynesia, Cape Verd Is. It is with considerable hesitation that I allow this to stand as a-distinct species from the preceding, with which it has much in 36 ZEUXIS. common. It has many synonyms: N. /filosa, Gray (fig. 134), N. graphitera, Beck (fig. 135), N. Reeveana, Dunker (fig. 136), N. dispar, A. Ad. (fig. 187), N. lurida, Gould (fig. 138), N. musiva, Gould (fig. 139), as well as probably the the following unfigured species , N. Kieneri, Anton, N. obliquata, A. Ad., N. plicatula, Dunker. The three following species appear to me to be mere varieties ot NV. picta, perhaps connecting it with N. gaudiosa: Var. MARMOREA, A. Ad. Fig. 140. Whitish, marbled with yellowish brown, the maculations some- times disposed in two or three bands. Length, 1 inch. Philippines, sandy mud, at 25 fathoms.—Cuming. Var. ALGIDA, Reeve. Fig. 141. Livid olive, blotched with white, and painted longitudinally with waved brown streaks. Length, 1 inch. ; Moreton Bay, Australia. Var. BICALLOSA, KE. A. Smith. Fig. 142. Whitish, livid at the sutures. Length, 1 inch. West Australia, Swan River, Cape Natal. The double tubercular callus at the base of the columella is not unfrequently developed in very heavy specimens of other species, and is an individual rather than specific character. N. conspersa, Phil. Pl. 11, figs. 143, 144. Shell very small, smooth, thick; yellowish or white, maculate with chocolate, forming on the body whorl two irregular bands. Length, *4—"5 inch. Canary Islands. Does not differ essentially from WN. picta, except by its much smaller size and heavier structure: it may well be a dwarf form of that species. N. Pfeifferi, Phil. (fig. 144), is synonymous. Several authors have recognized this shell as N. glaberrima, Gmel., but the description is indefinite, and the figures referred to are unrecognizable. N. HALpEMANI, Dunker. PI. 11, figs. 145, 146. Whitish, marbled with yellowish brown or chestnut zebra-like markings, smooth and polished, initial whorls longitudinally plicate, base of body whorl with revolving impressed lines. Length, *5 inch. East Indies. ZEUXIS. 37 Besides the typical figure, I give a drawing of one of four specimens in the Museum of the Philadelphia Academy, which I identify with this species (fig. 146). N. insienis, H. Adams. PI. 11, fig. 147. ‘“ Smooth, yellowish brown, with three revolving bands of chest- nut maculations. Length, 11 mill. River Petho, China. Said to have been found in company with Velorita, and there- fore possibly a brackish-water species. Mr. Adams has proposed for this shell the generic name Nassodonta, and refers it to the family Bueccinide. The generic character is the development of a tubercle within the thickened margin of the lip, and rather above the periphery—a position in which, according to experi- ence, such a feature ought to be regarded as abnormal. It is just possible that this shell is a Melanian. N. cornicutuM, Olivi. Pl. 11, figs. 148-150; pl. 12, figs. 151-153. Upper whorls finely plicate or smooth, three last whorls smooth, impressed revolving lines on base, or sometimes entire surface of body whorl. A very thin horny epidermis covers fresh specimens. Yellowish or reddish brown, with usually, a pale central band; sometimes maculated with white and brown at the sutures, sometimes finely maculated over the entire sur- face, with red-brown, sometimes trifasciate, or the bands broken up into maculations. Salmon-colored within the aperture. Length, ‘5-75 inch. Mediterranean Sea, Atlantic Coasts of Southern Europe, and Northern Africa. A protean species, which, together with V. conspersa, Messrs. Adams have referred to Amycla in Columbellide: the shell, animal and dentition, are decidedly Nassoid, however. N. semv- striata, Brocchi (fig. 150), a fossil form, is considered distinct by some of the best European conchologists, and N. trifasciata, A. Ad. (unfigured), is made one of its synonyms; whilst J. Gallandiana, Fischer (fig. 152), is regarded as a variety of it. I am not able to separate these from corniculum. N. Tinei, Marav. (fig. 153), is also doubtfully referred to corniculum: it is immature, possibly distorted in growth; and perhaps badly 38 ACICULINA. figured. N. quercina, Marrat, published without figure, locality or dimensions, is stated by Marrat to be “nearly allied to that very variable shell N. corniculum, Olivi, and may be only a variety of it.” N. 1nscuLpta, Carpenter. PI. 12, fig. 154. Shell with close revolving striz,-upper whorls of spire slightly costate longitudinally; light yellowish brown, interruptedly fasciate or marked with chestnut. Length, -75 inch. Catalina Island, Cal. —40 fathoms. I owe to the kindness of Mr. R. E. C. Stearns, the opportunity of illustrating this rare and hitherto unfigured species. Subgenus Aciculina, H. and A. Ad. The characters “outer lip produced in the middle, variced externally,” do not hold good for all the species: in fact, Acicu- lina differs from Zeuxis only in the species being longer in pro- portion to their width—still, it will be convenient to retain it. N. ANTHRACINA, Garrett. Pl. 12, fig. 155. Smooth, with fine revolving impressed lines. Black or black- ish brown, with a light brown line on the upper part of the body whorl; aperture brown within. Length, 7 mill. Viti Isles Only two specimens obtained, of which one (the type figured ) is in the’ Museum of the Philadelphia Academy. Somewhat resembles a Planawxis, but is a true Nassa. N. GpaBRATA, A. Ad. PI. 12, figs. 156, 157. Smooth, pupiform, slightly costate at the apex, with fine revolving striz on the body whorl. Olive brown, sometimes banded with ash-color. Length, ‘5-*6 inch. Philippines, Aracan, Solomon Islands. I have unicolored specimens before me, and specimens have been collected with from one to three bands. N. Pupinoides, Reeve (for WN. striata, A. Ad., preoccupied), is a synonym (fig. 157). N. macunaTa, A. Ad. Pl. 12, figs. 158, 159. Polished, with sometimes slight indications of rounded ribs and revolving basal striations. Whitish, longitudinally macu- lated with chestnut, frequently disposed in two revolving series or interrupted bands. Length, °5 inch. Philippines. ~e PHRONTIS. 39 N. vittata, A. Ad. (fig. 159), is a synonym. N. serotina, A. Ad. PI..12, fig. 160. Yellowish brown, shining, lighter at the sutures. Length, *5—7 inch. Australia, Cupe of Good Hope. N. waBiatTa, A. Ad. Pl. 12, figs. 161, 162. Yellowish brown or ash-color, obscurely light banded in the middle. Length, ‘7 inch. Malacea. N. Terebroides, Reeve (fig. 162), is a synonym, the flexuous sinus of the upper end of the lip figured in JN. labiata, being nothing but an individual variation. N. ELATA, Gould. Pl. 11, fig. 125. Whorls eight, flattened, turrited, with a marginal line near the suture; six upper ones with distant, acute folds; penultimate and upper half of body whorl smooth; lower part of the latter with half-a-dozen regular, deeply impressed, revolving striz. Length, ‘7 inch. Africa. I am not acquainted with the species. Subgenus Phrontis, H. and A. Adams. N. LuTEostoMA, Brod. and Sowb. PI. 12, figs. 163-165. Olive brown or ash-color, sometimes with a broad black or narrow white band; lip.and expanded callus orange. Length, *9-1'2 inches. Panama to Mazatlan. N. luteostoma, Kiener (fig. 163), is a synonym: its locality is erroneously given “Senegal.” N. wanthostoma, Gray (fig. 165)‘ is also synonymous. — N. TEGULA, Reeve. PI. 12, figs. 166, 167. Ash-color, usually lighter below the sutures and on the nodules, with a light band just below the nodulous shoulder ; aperture dark within, but showing the whitish band; lip and columella callus white. Length, -5--75 inch. Galapagos; Panama (Cuming); Mazatlan; Southern Coast of California. 40 PHRONTIS. The name adopted for this species is not the earliest one, but it is too well established to be superseded without disadvantage to science, especially as N. glauca, OC. B. Ad. (fig. 167), which has a year’s priority of publication, is not positively identified. Several Pacific Islands and East Indian species have been sup- posed by Carpenter, Marrat, Pease and others to be identical, but though resembling tegula in sculpture, the painting in all these is different. N. ANNELLIFERA, Reeve. PI. 12, fig. 168. Yellowish, encircled by bands of brown, thread-like lines. Length, ‘7 inch. Habitat unknoune I know nothing about this species. N. Sanct#-HELen#, A. Adams. PI. 12, fig. 169. White, interruptedly banded with red. Length, °3 inch. St. Helena, in sandy mud, at 20 fathoms. —Cuming. Said to resemble N. ambigua, Mont. N. optusaTa, A. Ad. Pl. 12, fig. 170. Whitish, filleted with red spots or interruptedly banded. Length, *65 inch. I. of Ticao, Philippines (in coral sand, at 7 fathoms. —Cuming). “ Chiefly distinguished,” says Reeve, “by the obtuse, widely separated character of the ribs, and the fine-ridged sculpture of the interstices.”” I have before me a series of specimens. said to come from the Straits of Malacca, which correspond well with the figure of this species. They are heavier, larger and more quadrate in form, yet closely resembling the West Indian N. ambigua. N. FISSILABRIS, A. Ad. PI. 12, figs. 171-1738, L179. Ash-colored, faintly light banded, or whitish and interruptedly red-banded. Length, 6-75 inch. Philippines. The posterior channel of the aperture, may have been more developed than usual in the type of this species, but it is a character which pervades most of the species of this group. WJ. nodicostata, A. Ad. (fig. 172), N. erenolirata, A. Ad. (fig. 179), and N. Stearnsiana (Garrett), Marrat, are equivalent forms—the PHRONTIS. 4] latter being unfigured and undeseribed. N. albipunclata, Reeve (fig. 173), said to have faint white-dotted bands, but which are not shown by the figure, can scarcely be different. N. TIARULA,.Kiener. PI. 12, figs. 174-178. Ribs few, rounded, prominent; whorls broadly shouldered and frequently tuberculated on the shoulder. White, with a single central, or several interrupted, narrow, brown bands. Length, *5—6 inch. Solomon's Is , Philippines, ? Madagascar, Kiener. This is a more quadrate, solid, smaller form than the pre- ceding. It, as well as some of its synonyms, has been referred to N. tegula, Reeve, by such experienced students as Pease, Carpenter, Marrat: I think, however, that the form and colora- tion and difference of habitat, will justify a separation. I add to Kiener’s figure (fig. 174) one by Reeve, in which the ribs are obsolete (fig. 175). NN. coronula, A. Ad. (fig. 176), N. delicata, A. Ad. (fig. 177), are synonyms. WN. trinodosa, E. A. Smith (fig. 178), from Solomon’s Is., is probably a variety of this species, although it has partly the features of N. subspinosa, Lam. N. cincrenna, Gould. Pl. 13, figs. 180-182. Shoulder rounded, ribs narrow, strongly laticed by revolving lines. White, with sometimes a narrow median brown band. Length, °45-—6 inch. Philippines, Central Polynesia. N. clathratula, A. Ad. (fig. 182,is synonymous. N. cinctella, A. Ad. (fig. 181), from St. Helena, is very close, if not identical. N. niegra, Hombr. et Jacg. PI. 13, figs. 183-187. Dark chocolate-color within and without, with usually a light band. Length, *5—-65 inch. Philippines. With this I unite \. lirata, Marrat, which I figure from an author’s type (fig. 184°, N. Deshayesiana, Issel (fig. 185), in which the ribs, especially round the upper part of the body whorl, are more or less nodulous, NV. scalarina, Marrat (fig. 186). I am inclined to believe that NV. Nova-Zealandix, Reeve (fig. 187), is merely a variety. 6 492 PHRONTIS. N. crassa, Koch. Pl. 13, figs. 188-190. ; Yellowish or greyish, with usually a superior white band. Very thick, ribs rather small, broken into granules. Length, *6—"75 inch. China, Viti Isles. Fig. 188 is a copy of the type, said to come from China, but that locality is doubtful: the more usual form of the species is that of fig. 189. N. semisulcata, Hombr. et Jacq. (fig. 190), is : synonym. The species is remarkable for the ponderous thick- ness of well-grown individuals. N. mica, Brug. PI. 13, figs. 191-193. Obliquely costate, costa sigmoid, with close revolving strix which are frequently obsolete on the body whorl except its lower part. Yellowish or orange-red, banded; or sometimes parti-colored on the body whorl, the lower portion being darker. Length, 5-7 inch. West Africa. Fig. 192 represents an elongated variety, and fig. 193 is N. obliqueplicata, Dunker. N. amMBiaua, Mont. Pl. 13, figs. 194-197, 213. Narrowly shouldered, ribs pretty close, crossed as weil as the interstices by tine revolving lines. White or yellowish, generally banded, spotted or maculated with brown. Length, 4-55 inch. West Indies, West Coast of Africa. —Dunker. First described by Montagu as a British species, and oceca- sionally found on the western shores of Europe, but its occurrence is adventitious. Its more scalariform spire, finer sculpture, color, absence of the strong nodules, and narrow, defined columella callus will serve to distinguish it from JN. vibea, Say. The synonyms are N. Antillarum (fig. 194), N. Cande?, (fig. 195) and N. Hotessieri (fig. 196), all of @’Orb., and all immature shells, of different ages; and N. acuta, Say (fig. 197), probably. N. consensa, Ravenal, is very poorly described from a single specimen found in a fish at Charleston, 8. C. It is probably this species. N. VIBEX, Say. Pl. 13, figs. 198-207. Spire turrited, angulated by a nodulous series on each whorl, body with a rather broad, sloping shoulder, the border of which HEBRA. 45 is defined by nodules ; ribs not close, frequently broken into nodules by the revolving striz ; columella callus rather widely spread. Usually olive, chocolate or nearly black, light banded on the periphery and flecked with revolving chestnut spots ; sometimes the shell is nearly white, and then, whilst retaining the red spots, the band is also red, or absent. Length, “6-8 inch. West Indies ; Atlantic Coust of the United States, northward to Chesapeake Bay ; Rio Janeiro, Brazil. Say’s type was a stunted specimen, and is badly figured (fig. 198). Reeve’s figure represents a very different species, a juven- ile N. subspinosa, Lam., from the Philippines ; but 1. Antillarum, Phil. (figs. 199-201 , and N. Sturmii, Phil. (fig. 202), will give a fair representation of the usual range of the species in size and color. WM. tessellata, Reeve (fig. 203), MW. fida, Reeve (fig. 204), both described without locality, and N. cinisculus, Reeve (fig. 205), from St. Thomas, W. I., are alsosynonyms. WV. Fretenses, Perkins (fig. 206), is supposed by its author to possess distin- guishing characters in its proportions, sculpture and color, but it is well within the range of variation of .\. vibe, in all these particulars: it is found, though rarely, at New Haven, Conn., and near Salem, Mass., and may have been carried there with southern oysters. N. paucicostata, Marrat, an unfigured species from Nassau (Bahamas ?), is also a probable synonym. N. poly- gonata, Lam. (fig. 207), is certainly very closely allied to N. vibex ; it has been misunderstood by Reeve, who has figured for it a very different species, and Kiener has confounded with it NV. Jacksoniana, Quoy, a var. of N. monile, Kiener. Subgenus Hebra, Il. ard A. Adams. I retain this group after modifying the original diagnosis, which only applies to immature specimens. The muricated or spinose ornamentation forms a convenient separation from Phrontis, and the columella callus is also more defined, but the spire is not “elevated” more than usual, nor is the outer lip without varix or denticulations, when mature. N. susspinosa, Lam. Pl. 13, figs. 208-212. Spiny, nodulous, the nodules generally forming three promi- nent revolving series on the body-whorl, but sometimes subor- 44 ‘ HEBRA. dinated to the longitudinal ribs. © Ash-color to dark chocolate, mostly light banded between the spiral rows of tubercles. Length, *6—7 inch. Indian Ocean, Philippines, New Zealand, Central Polynesia. XN. viber, Reeve, not Say (fig. 209), is an elongated, immature shell of this species: to which I refer also, N. yeniculata, A. Ad. (fig. 210), and WN. sistrvidea, G. and H. Nevill (fig. 211). NV. scalpta, Marrat (fig. 212 , is described as passing into N. sub- spinosa on the one hand and NN. corticata on the other. N. MURICATA, Quoy and Gaimard. PI. 14, figs. 214-218. Whitish or yellowish, with narrow bands or blotches of chest- nut or chocolate. Indian Ocean, Madagascar, New Ircland, Polynesia. Mr. Marrat considers this a variety of NV. subspinosa, Lam., und he is probably correct—yet the less developed shoulder, more swollen periphery, more numerous, smaller and decidedly prickly tubercles, as well as lighter color, constitute characters deserving of recognition, I think. With it are to be united J. horrida, Dunker (fig. 216), N. Gruneri, Reeve (fig. 217), and N. curta, Gould (fig. 218). N. GruneERI, Dunker. Pl. 14, figs. 219-222. White or yellowish, sometimes obscurely banded or spotted. Length, 65-8 inch. Philippines, Distinguished by its regular, close sculpture of bead-like tubercles, forming both longitudinal and revolving series. The synonyms are N. hispida, A. Ad. (fig. 220), N. Websei, Petit (fig. 221), said to come from West Coast of Africa (doubtful), and N. acinosa, Gould (fig. 222). N. ecuinataA, A. Ad. PI. 14, figs. 223, 224. Yellowish white, longitudinally flecked with brown. Length, ‘7 inch. Philippines, China, Andaman Isles. This pupa-like species is a form rather unusual in the genus : it may be only a scalariform monstrosity of N. muricata. 1 have not seen specimens of it. Those from the Andamans are said to be proportionally shorter than the type. N. nodulifera, Phil. (fig. 224 , is probably the same species: it is said to come from China. If identical, it will have priority. HIMA. 49 Subgenus Hima, Leach. N. sToLATA, Gmel. PI. 14, fig: 225. Whitish or yellowish, with a broad chocolate band on the _ periphery, and usually a narrower, subsutural one. : Length, *75-1 inch. Y Indian Ocean, N. pacopa, Reeve. Pl. 14, figs. 226-228. Whitish or yellowish, stained or obscurely banded with brown. Length, *8—1'2 inches. Galapagos Is., Panama to Mazatlan. Kiener’s NV. decussata (fig. 227) is synonymous, and his locality “'W. Coast. of Africa,” as well as that given by Reeve for decussata “* Brisbane Water, E. Australia,’ are both erroneous. N. angulifera, A. Ad. (fig. 228),is a juvenile shell; it comes from Galapagos (at ten fathoms), on the authority of Cuming. N. canescens, C. B. Ad., and N. acuta, Carpenter (not Say), both unfigured, are evidently the same species. N. Trrronirogmis, Kiener. Pl. 14, figs. 229, 230. Yellowish, ash-color, or light brown; columella-callus and lip white. Length, 1 inch. Philippines, on mud tlats—Cuming ; Coriseo Bay —Marrat. N. fuscata, A. Ad. (fig. 230), is probably the same species. N. myristica, Hinds. Pl. 14, figs. 231, 232. Light brown, the revolving ridges darker, sometimes dark- spotted below the sutures. Length, 1 inch. Cape of Good Hope. Notwithstanding the greater prominence of the revolving ridges, more undulating longitudinal sculpture,and more rugose columella, I doubt the distinctness of this from M. Tritoni- formis. Var. RUFOLINEATA, Marrat. Fig. 23: Whitish or yellowish, stained or lineated with brown. Length, °9 inch. Philippines. _ It is the NV. polygonata of Reeve (not Lamarck), and differs trom the typical N. myristica only in being shorter and broader. 46 TIMA. N. SCABRIUSCULA, Powis. Pl. 14, figs. 233-235. Brownish, or usually ash-color, with a superior white band, which is oceasionally visible on the spire; revolving lines some- times chestnut-brown. Length, *6—75 inch. Panama. N. collaria, Gould (fig. 284), and N. Stimpsoniana, C. B. Ad. (fig. 235), appear to be equivalent forms. N. nopata, Hinds. PI. 14, fig. 236. Yellowish brown, with one or two faint chocolate bands. Length, ‘8 inch. Straits of Malacca. N. FascraTa, Lam. PI. 14, figs. 237, 238. Whitish, with a central chestnut band, tinged with chestnut at the base. Length, 65-9 inch. South Australia. The whole surface of this species is beautifully granulated. N. FesTIVA, Powis. PI. 14, figs. 239-242. Longitudinal ribs coarsely latticed by strong, close, rounded, revolving riblets. Whitish, interstices of riblets chestnut or chocolate color; columella and lip white. Length, ‘7-85 inch. Japan. N. festiva is said to have been dredged by Cuming at Panama and St. Elena (in sandy mud at six to ten fathoms), but I am not aware that either locality has been confirmed. The next species (N. dentifera, Powis) is a native of those regions, but is constantly distinguished by being thinner, more swollen, and dark chocolate color within and without. The Japanese habitat is undoubted. The synonyms are N. lirata, Dunker (fig. 240), N. dealbata, A. Ad. (fig. 241),a somewhat narrower form, usually white, with a central brown band—it might perhaps be dis- tinguished as a variety, and N. acutidentata, EK. A. Smith (fig. 242°. N. DENTIFERA, Powis. PI. 14, figs. 243-245. Chocolate-brown within and without, with occasionally an obscure lighter central band. Length, ‘7-85 inch. Panama to Callao, Peru. N. unidentata, Powis (fig. 244), is an immature shell, and a still younger one is N. Tschudi, Troschel (fig. 245’. To these HIMA. 47 synonyms should probably be added N. corpulenta, C. B. Ad. (unfigured), from Panama. N. apyssicona, A. Ad. PI. 15, fig. 255. Dirty white, slightly bead-margined at the sutures. Length, °33 inch. Isle of Bohol, Ph#lippines, in clayey ground, at sixty fathoms—Cuming. I do not know this species. N. pAuPERA, Gould. Pl. 15, figs. 246-250. Elevated, narrow, whorls rounded, closely costate, and with fine revolving lines ; aperture small,rounded. White or yellowish, sometimes fasciated with brown, or marbled, or with the lower half of the body-whorl brown. Length, °35—"5 inch.’ Japan, Australia, Central Polynesia. Ditters from the Nassw preceding it in this group by its pupi- form shape and comparatively small body-whorl and mouth. The spire is sometimes much exserted, causing very deep sutures. The variable painting, etc., has caused a very large synonymy, namely—N. plebecuia, Gould (unfigured), N. micros- toma, Pease (fig. 247), N. wnifasciata and N. turricula, Pease MS., N. balteata, Pease (fig. 248), N. dermestina, Gould (un- figured). N. fraterculus, Dunker (fig. 249), is a stouter form, which may possibly be identical with the next species. NV. Samoensis, Dunker MS., and N. /uteola, E. A. Smith (fig. 250), from Japan, described from a single dead specimen, are very probably synonyms. N. TRINGA, Souverbie. Pl. 15, figs. 251, 252. Yellowish brown, sometimes mottled with chestnut, and spotted on the varix of the lip. New Caledonia, S. Australia. With this I unite N. compacta, Angas, of which I am able to give a figure from a specimen (fig. 252); it is the Australian rep- resentative of the European JN. incrassata. N. penticunatTa, A. Ad.

Length, ‘55 inch, Habitat unknown. Much more slender than the typical N. paupera, yet I doubt its distinctness. I have before mea single specimen which is just intermediate between the two forms, N. eximia, H. Adams. PI, 15, fig, 257, Cancellated by very close, small longitudinal and revolving lines; light yellowish brown, with three pale brown revolving bands. Length, 8 mill. New Hebrides ; Viti Islands —A. Garrett. Still mere pupiform than NV. paupera, and smaller, with much finer sculpture. N, pusilla, Marrat, an unfigured species from Singapore, is probably (judging from the description) identical. N. concinna, Powis, Pl. 15, figs. 256, 258-259. Closely cancellated, with an impressed line at the suture, dividing offa single row of granules, Length, *65—'8 inch. Polynesia ; Australia. In form, sculpture and coloring like the preceding species, but differing greatly in bulk. N. crebrilineata, Hombr. and Jacq. (fig. 258), and probably N, pulcherrima, Marrat (fig, 259), are synonyms. ; ® N. INTERLIRATA, E. A. Smith. Pl. 15, fig. 261, With spiral lire in the interstices of the longitudinal riblets. Dark brown, blackish beneath the sutures. Length, 6°5 mill. San Christocal, Solomon Islands. HIMA. 49 N. nuciEouvs, Phil. Pl. 15, fig. 262. Whitish, brown at suture and base, with usually a brown central band. Length, 5—6°5 mill. ‘ Mazatlan ; Acapuleo —W. M. Gabb. This is one of the few Mazatlan species unknown to Carpen- ter; it is a very distinct and pretty form. N. INCRASSATA, Strdém. PI. 15, figs. 263-266. Brownish white, usually obscurely maculate or banded with brown; whorls with or without a slight shoulder; shell broad to elongated ovate; occasionally (in some specimens) with a varix crossing the whorl; lip varix strong, usually with three brown spots. Length, -45—6 inch. Iceland, and North Ewrope to Azores, Mediterranean. Fossil, widely distributed in European tertiary and quaternary deposits. .Owing to the great variability of this species, it has received numerous names: one of these forms, indeed, is usually separated by some of the best European conchologists, and it will be as well, perhaps, to designate it as var. pygmza, although the immense series of specimens before me compels me to agree with Dr. von Martens, that it has no real claim to specific dis- tinctness. Var. praMZA, Lam. Fig. 265. Shell narrower and more finely sculptured; whorls rounded, not angulated above; spire proportionately longer. N. incrassala is a very active mollusk, and now and then changes its crawling position by leisurely floating with its foot upwards. It often gets into lobster and whelk pots. The spawn cases are solitary, yellowish, and shaped like a round flask, with a small neck or opening at the top. N. RosAcEA, Reeve. PI. 15, fig. 267. Deep rose-color, black edged at the base, lip white. Length, 8°5 mill. . Habitat unknown. May be a variety of N. incrassata. N. prompta, Marrat. Ovately conical, highly polished, pale yellowish white, with two reddish-purple dotted bands, one in the centre of the body- a 50 HIMA. whorl, the other near the canal at the base, whorls rather flattened, ribbed to the base in front and not more than half-way down behind, raised into blunt nodules at the sutures, aperture semi- lunate, columella thickened but not spreading, tubercular, outer lip very thick, with a thin edge near the aperture; throat with rather strong and somewhat distant ridges, canal very short, stained on each side of the base with brown. This may be only a variety of that interminable shell, V. incrassata, Mull., but I have not seen any varieties that are likely to connect them. The above is Marrat’s description; no figure, dimensions or locality. N. ALBA, Say. Shell white. IL. -45, lat. °3 inch. Southern Coast of E. Florida, West Indies. The sculpture of this species is said to be similar to that of N. incrassata, with which Say compares it. It has not been identified by later investigators. Unfigured. N. TENELLA, Reeve. PI. 15, figs. 268, 273. Semitransparent orange, tinged with rose towards the apex, transversely grooved, longitudinally flexuously ribbed, aperture small, columella callous, lip thickly varicose, varix white. Length, *5 inch. Cascues Bay, Portugal. Possibly a variety of N. inerassata, var. pygmea, which it appears to connect with the next species. N. Cochinensis, Thorpe, appears to be an unpublished species, although alluded to by Mr. Marrat ; specimens under that name received from Mr. Sylvanus Hanley, are before me—they do not differ essentially from the figure of N. tenella, Reeve. The description of N. argentea, Marrat (fig. 273), from W. Africa, agrees very well with NV. tenella. N. DEsHAYESII, Drouet. Pl. 15, fig. 269. Violaceous, with brown revolving lines. Length, 15 mill. Azores. See remark under preceding species. N. versicotor, C. B. Ad. PI. 15, figs. 270-272, 275. Yellowish brown, lower part of body-whorl and sutures usually chestnut-colored. Length, 13 mill. Panama to Mazatlan. NIOTHA. 51 The ribs are few, rather broadly rounded, color variable. XN. proxima, and N. striata (fig. 271), of C. B. Ad., N. rufocincta, A. Ad. (fig. 272), N. crebristriata, Carpenter (unfigured), and N. Lecadrei, Folin (fig. 275), are synonyms. N. sinusigErA, A. Ad. PI. 15, figs. 274, 276-278. Whitish, stained or filleted with red-brown; ribs slightly granulated at the sutures, lips varicose, sinuated at the lower part. Length, °5 inch. Philippines, Mauritius. The lip-sinus is not, probably, distinctive. G. and H. Nevill figure a variety cernica (fig. 276) from Mauritius. N. fraudulenta, Marr. (fig. 277), from Philippines, and N. cribraria, Marr. (fig. 278), habitat unknown, are, judging from figures and descrip- tions, at least very closely related. Subg- nus Niotha, 1H. and A. Adams. The difference between this group and Alectrion is very slight, yet its retention will possibly facilitate the classification of the species; it includes those shells having a reticulated or cancel- lated surface in consequence of the longitudinal and revolving sculpture being about equally prominent, whereas in Alectrion either the whorls are smooth or the longitudinal ribs are much more prominent than the revolving striz. In both, the inner lip- callus is spread over the body-whorl, and the outer lip is with- out external varix. N. AuBEscens, Dunker. PI. 16, figs. 279-283. White or yellowish, sometimes with faintly marked ash- colored bands, which are chocolate-colored within the white aperture; first whorls usually dark ash-color. Length, 15-20 mill. Japan, Philippines, Polynesia, Australia, Mozambique, Andaman Isles. The typical form of this species is easily recognized by its faint bands and dark apex; of this type is N. bicolor, Hombr. et Jacq. (fig. 280). There is a gradual variation from this to the next species, so that it is difficult to decide where the one should end and the other commence; among these varieties are N. Fenestrata, Marr. (fig. 281), a somewhat more ovate form, the 52 NIOTHA. name proposed for N. Jsabellei, Reeve, not Orb., N. Keenzi, Marr., which I figure from an author’s specimen (fig. 282), NM. gemmulifera, A. Ad. (fig. 283). N. sPLENDIDULA, Dunker. PI. 16, figs. 284-287. White, shining, sharply granose by the crossing of the longi- tudinal ribs by deeply incised lines ; occasionally marbled with light chestnut, or spotted with the same next the suture; suture deeply channeled. Length, ‘6-75 inch. Philippines, Malacca, Polynesia. Very close to N. albescens, and perhaps only a variety of that species; the tubercles are more sharp-set, the revolving lines more distant and regularly spaced—not occasionally approxi- mating in pairs as in albescens. The synonyms are N. semi- granosa, Dkr. (fig. 285), N. ravida, A. Ad. (fig. 286), and N. densigranata, Reeve (fig. 287). N. nivosa, Marrat, and N. crispata, Marrat, are unfigured species compared by the author to this form. N. PAUPERATA, Lam. PI. 16, figs. 288-291. Banded with chestnut on the periphery and at the base of the body-whorl, columella and lip-margin sometimes tinged with chestnut. Ribs becoming evanescent below the middle of the body-whorl, cut into tubercles by the revolving lines, a row of these tubercles below the suture, more prominent and separated from the rest by a suleus. Length, °5—-75 inch. S. Australia, Tasmania. N. lyrella, Beck (fig. 289), is a white or bleached specimen of this species, not in good condition, and I think that N#multi- granosa, Dunker (fig. 290), is the juvenile, and N. caperata, Phil. (fig. 271), a pigmy adult of the same species. N. sorpipa, A. Ad. PI. 16, fig. 292. Yellowish, obscurely banded with light brown. Length, °65 ineh. Philippines. The suture is somewhat channeled, the ribs rather sharp, the revolving impressed lines rather faint. This, as well as the. following species may be only varietal forms of N. albescens. —— NIOTHA. a5 N. CANDENS, Hinds. PI. 16, figs. 293, 294. Yellowish white, marbled or fasciate with chestnut; a row of granules below the suture, and close, prickly granulations cover- ing the whorls, caused by the incised revolving lines. Length, ‘7-9 inch. Marquesas Isles. N. ckeMATA, Hinds. PI. 16, figs. 295-300. The whorls are usually channeled below the sutures so as to separate a single row of nodules, and the close ribs are crossed by closer revolving incised lines. The color is yellowish or whitish, banded or irregularly marbled with brown or ash color. Length, *75-1 inch. Sts. of Malacca, Philippines, Polynesia. The taller spire, beaded line beneath the suture, prominence of the longitudinal sculpture, etc., are the distinctive features of this species—which connects undoubtedly with NV. albescens on the one hand, and with concinna on the other. Hinds’ shell is not adult (fig. 295), and does not exhibit the usual appearance of the species so well as does N. Quoyi, Hombr. (fig. 296), or N. Sragum, Hombr. (fig. 297). ‘Var. MARGARITIFERA, Dunker. Figs. 298-300. The longitudinal ribs are narrower, sharp edged, the revolving sculpture coarse, obsolete in the middle of the body-whorl. Besides the brown or chocolate bands or blotches, the surface is numerously spotted on the sides of the small tubercles with chestnut-brown. N. venusta, Dunker (fig. 299), N. costellifera A. Ad. (fig. 300), are synonyms. N. Krenert, Desh. PI. 16, figs. 301-303. Longitudinal ribs prominent, upper margin of each whorl tuberculated, incised revolving lines faint except towards the base, where they cut up the ribs into tubercles; white with chocolate or chestnut superior and median bands; surface some- what polished. Length, ‘75-1 inch. Singapore, Polynesia, Isle of Bourbon. The more prominent, less decussated longitudinal sculpture is the chief distinction from N. cremata, Hinds, the incised re- volving lines from JV. monile, Kiener—which it most nearly a4 NIOTHA. resembles in its coloring and polished surface. That a series could be arranged to show the gradual transition from one to the other of these species, although arranged in different groups, cannot be doubted. The synonyms are N. marginulata, Reeve not Lam. (fig. 301), called N. Kieneri by Deshayes, N. mar- garitifera, Reeve, not Dunker (fig. 302), and N. Isabellei, Reeve, not d’Orb. (fig. 303). , N. tivescens, Phil. Pl. 16, fig. 304. Yellowish, clouded with light chestnut. Length, -8—-9 inch. India, Chinese Sea, Philippines. This species has the form of albescens, with the revolving sculpture of cremata and ribs of concinna. N. pusto, A. Ad. Pl. 16, fig. 305. Fulvous, variegated and spotted with brown. Length, -28 inch. Luzon, Philippines, in coarse sand, at six fathoms —Cuming. This shell is globosely oval, with fine ribs and rather incon- spicuous revolving striz. N. mutticostata, A. Ad. Pl. 16, fig. 306. White, variegated with pale red; revolving striz obsolete. Length, ‘7 inch. Philippines, coarse sand, at four fathoms—Cuming. Proportionally longer, the ribs rather coarser, yet possibly an older example of N. pusio. N. verrucosa, A. Ad. Pl. 16, fig. 307. Yellowish, clouded with reddish brown. Length, 1 inch. Philippines. The tubercles are larger and more decidedly warty than in the succeeding species, the sutural channel is deeper, the spire more conical: yet it possibly is only an intermediate form between stigmaria and gemmulala, N. stigmaria, A. Ad. PI. 16, figs. 308-310. Whitish or yellowish, more or less clouded and marked with brown. Sculpture forming flat, somewhat square-shaped gran- ules, those forming a row around the deep (but not wide) suture, somewhat larger. Length, *75-1 inch. . Philippines, Malacca, Indian Ocean. TRITIA. 50 With this I unite N. cremata, Reeve, not Hinds — N. quad- rata, Marrat (fig. 309), and N. retecosa, A. Ad., not J. Sowb. = N. Adamsiana, Marrat (fig. 310). N. Cuminar, A. Ad. PI. 17, fig. 311. Ovate, rather ventricose, solid, suture flatly channeled. White, stained with faint chestnut-color. Length, 1 inch. China. Distinguished by the swollen character of the whorls—yet probably only an intermediate form between the last and next species. N. GEMMuLATA, Lam. Pl. 17, figs. 312-315. Yellowish white, stained and spotted with chestnut; suture flatly channeled. Length, 1 inch. Philippines, Sts. of Sunda. N. clathrata, Lam., Encye. Meth. (fig. 313), N. conoidalis, Desh. (fig. 315), and N. variegata, A. Ad. (fig. 314), are syn- onyms. Subgenus Tritia, Risso. Distinguished from Niotha by its narrow callus, yet some of the last species in that group form a passage into this. Cesia, H. and A. Adams, has no distinctive character, and must merge into Tritia as a synonym. Schizopyga, Conrad, founded on a miocene species (S. Californica, P|. 3, fig. 32), probably equiva- lent to N. perpinguis, Hinds, is also a synonym. * West Coast of America. N. rossata, Gould. PI. 17, figs. 316-318. Light. yellowish brown, interior of aperture and columella deep orange, the sharp, raised, revolving ribs of the interior white. Length, 1-2 inches. Coast of California, A magnificent and peculiar species, not to be mistaken for any other, and the largest in the genus. N. elegans, Reeve (fig. 317), very fairly represents it, the figure and description of Gould (fig. 316) being from a form more ventricose than usual, and not adult. N. elegans being preoccupied by J. Sowerby for a fossil species, Adams changed the name to N. Reevei—which falls before Gould’s prior name. To this synonymy is to be added N. Morleti, Crosse (fig. 318). 56 TRITIA. N. PeRPINGUIS, Hinds. PI. 17, fig. 319. Yellowish white, obscurely marked or banded with chestnut. Length, -75—-9 inch. California. Fossil specimens occur much larger, and varying considerably from the typical form; some of them approaching a small JN. Jossata in size and latitude. P. P. Carpenter considers N. in- terstriata, Conrad, a fossil equivalent—which is somewhat doubt- ful. Schizopyga Californica, Conrad, is probably identical : it is from the miocene. N. MENDIcA, Gould. PI. 17, figs. 320-323. Yellowish to reddish brown. Length, ‘5—7 inch. Puget’s Sound to San Diego, Cal. N. Woodward, Forbes (fig. 321), and N. Gibbesii, Cooper, are synonyms of this species ; which is the West Coast analogue of N. trivittata, Say. Var. Cooperi, Forbes. Figs. 322, 323. This is typically very distinct, with its seven or eight distant, prominent, shouldered ribs, but specimens are not rare which, commencing with the numerous ribs of N. mendica, suppress alternate ones and increase the prominence of those remaining on the body-whorl. There are also specimens intermediate in form and number of longitudinal ribs, and even some in which the ribs are obsolete on the body-whorl. As it is generally recognized as a distinct species, it may be convenient to retain its name as a variety. N. Gayl, Kiener. Pl. 17, figs. 324, 325. Yellowish brown to chestnut-color; longitudinal sculpture usually the most prominent, but sometimes obsolete; a row of bead-like granules usually, next below the sutures. Length, 15-18 mill. W.

Length, 3°5 mill. Wydah, W. Africa. Is this really distinct from the preceding species? At any rate the shell is so decidedly immature that it ought not to have been described. 8 [ob 4] 8 TRITIA, N. Kocniana, Dunker.. PI. 17, fig. 334. Yellowish white, variegated with chestnut. Length, 3-4 mill. Table Bay, So. Africa. Another immature and doubtful species. N. PLICATELLA, A. Ad. PI. 11, fig. 335. Yellowish, stained with light brown or ash. Length, 1 inch. Wallwich Bay, So. Africa. Very closely allied to the European WN. reticulata. *** Atlantic Ocean and Mediterranean Sea. N. cLATHRATA, Born. PI. 17, figs. 336-339. Shell turreted, rather thin, suture flatly, narrowly channeled, whitish, irregularly yellow-banded in the middle; a deep suleus at the base of the body-whorl. Length, *9-1:25 inch. Mediterranean Sea ; Madeira ; Canaries. Seldom found living, but.extensively distributed as a miocene and pliocene fossil. It isa very variable form, and Weinkautt even suspects that .V. miga, Lamarck, will prove to be a variety —which is not unlikely. The oldest name used for the species is that which I have adopted, and it has the advantage of being binomial, whilst the later and generally adopted name, N. limata, Chemnitz, is only a portion of the phrase given in that work. . prismatica, Brocchi (fig. 337), and N. elegans, Dujar- din are synonyms among the fossil specimens. Mr. Marrat figures for N. turrita, A. Ad. (fig. 338),a shell which is certainly identical with this species. N. scatariforiis, Val. (fig. 339), is not adult. N. RETICULATA, Linn. PI. 18, figs. 340-345. Yellowish white, light chestnut or chocolate-color ; sculpture varying considerably, but the longitudinal ribs are usually the most prominent, flexuous, distant, or numerous and close; o¢ca- sionally the suture is beaded so as to resemble N. monile, Kiener Lenyth, °75-1°25 inch.

It also gets into lobster-pots for the sake of the bait. Bouchard-Chantereaux attributes to this as well as to other whelks, the habit of piercing and devouring bi- valves. According to M. Lespés, N. reticulata is preyed upon by a parasitic Trematode (Cercaria sagittata) which infests its liver. Its spawn cases are deposited on the leaves of Zostera and on various other things which are left dry only at spring tides ; the capsules are arranged in rows, and so closely that they overlie each other “like the brass scales of the cheek-band of a hussar”’ (Johnston). They are compressed pouches, each of the size of a large spangle, supported on a very short stalk, with a small opening at the top to allow the fry to escape. Mr. Peach des- cribed and figured the capsules in the Reports of two Cornish Societies for 1843 and 1844; and he has given us some amusing particulars of the fry. These behaved themselves like the fry of other gastropods, skipping about and whirling round by means of their ciliated lobes, apparently in a state of pleasura- ble excitement ; but it seems that the exercise was compulsory, or necessary to prevent the attacks of a swarm of infusoria, which made short work of any tired or feeble infant Nassa. Mr. Jeffreys has named N. nitida (fig. 340) a shell which he says is as distinct from N. reticulata as N. pygmea is from N. incrassata, and he states that he has not seen any intermediate forms. He states that nitida is found only in brackish water and on muddy bottoms. A specimen among a number dredged by him in Roach River, had two eyes on the right hand tentacle; the eyes were smaller than usual, and close together. I agree with Moérch and Von Martens that nitida is merely a variety of N. reticulata. Myr. Jeffreys cites N. reticulata from Japan; * the identity of the Japanese shell must be supposed to be in the sense in which Mr. Marrat would regard it—yet I can admit it also, if it be considered necessary to prove an immense distri- bution for the species. N. reticulata, figured by Quoy and Gaimard in the Voy. of the Astrolabe, is no* this species how- ever, but probably N. cremata, var. margaritifera. A curious, thin, swollen form froni the Baltic is known as WN. cancellata, Chemn (figs. 343-345). * Jour. Linn. Soc., xii, 107. 60 ILYANABSA. N. trRivitTaTa, Say. Pl. 18, fig. 346.

Leneth, ‘7-9 inch. | Massachusetts to Florida. The animal is whitish, sparsely dotted with pale lilac; foot slightly bifid behind with two erect subulate processes. Very active. Comes out of the sand towards low-water mark, in a minute or two after the water passes over them. On most specimens the bands on the shell are either obsolete or so faintly marked as to escape hurried observation. ° Subgenus Ilyanassa, Stimpson. The generic characters proposed by Stimpson include an opereulum without serrated margin, and the animal without posterior bifurcation. Although the operculum is usually crenated in Nassa, Mr. Marrat has enumerated a dozen species in which it has been observed to have plain margins, or nearly so; and Dr. Von Martens states* that the European N. reticulata is found in the mud-fiats of the Venetian lagunes with the oper- culum plain on one side and somewhat serrated on the other, and that the end of the foot is but slightly notched in these specimens instead of being deeply bifurcated. Under these cir- cumstances, it becomes very doubtful whether the group Ilyanassa ought to stand. I have concluded to retain it pro- visionally as a subgenus, especially as it may include several species conveniently separable from Tvritia by having dark- colored shells. N. OBSOLETA, Say. PI. 18, figs. 347-349. Chocolate-brown or olive, with occasionally a faint, lighter colored central band; deep chocolate within the aperture, with a central white band. Length, °75—1 inch.

ILYANASSA. 61 Its movements are very active, and it collects in numbers about dead crabs and other marine animals, on which it feeds. Inhabits all our muddy shores, preferring situations not exposed to the surf of the open sea; such as inlets and extended flats which are drained at low tide. It is found abundantly at the con- fluence of fresh and salt water, where the taste is merely brackish. No shell of equal size is so abundant on the whole Atlantic shore. Specimens from Florida vary only in being smaller, more olivaceous, and by having a thick, broad callus over the pillar. The younger shells are most likely to be col- lected, because the old ones become very much eroded and defaced, and a greenish mould-like plant vegetates abundantly upon them. Very few, therefore, of the shells usually collected, ‘have the lines on the interior of the outer lip. Kiener’s figure (fig. 348 ., NV. olive formis, represents a young shell * The ova- capsules are laid during April and May, are of transparent corneous texture, singly attached to the inside surface of a valve ot Mactra, or the inner face of the nidus of Nafica; they are deposited in vast numbers, completely covering the object to which they are attached and crowded together promiscuously (fig. 349). , N.

Most of the above are from the collections of the North Pacific (U.S.) Exploring Expedition: they have not been figured, and the type specimens were destroyed in the great Chicago fire.

The following forty “species” are described (but not figured) by Mr. F. P. Marrat, who does not believe in species. I take them,-with great pleasure, at his own valuation, for I cannot afford to expend my time over diagnoses which should never have been written by a gentleman holding such opinions as Mr. Marrat does, as to the instability of every specific character. Theoretically, Mr. Marrat relegates all the Nass to one specific form; practically, he describes such individuals of that form as he likes to name; and if every other collector should adopt his views and be equally industrious, we should eventually have every individual specimen of the genus bearing a distinct specific name: moreover each collector would possess the sole specimens of his own species.

In Neritula the last whorl is depressed and extends over the penultimate whorl nearly covering and concealing the spire, which consequently appears very obtuse. The animal has a bifid tail, and operculum similar to Nassa. Risso’s name Cyclope has been almost equally used for this group. H. and A. Adams’ genus Teinostoma was originally placed next to Nerifula, ih their “Genera; subsequently they removed it to the Rotelline or Umboniine. N. NeRITEA, Linn. PI. 18, figs. 353-356, 359. Shell smooth and polished; ‘fulvous minutely speckled with chestnut-brown, with usually darker and larger markings, form- ing a sutural band and another upon the periphery; the callous, flattened columella, yellowish stained with brown, is spread out in circular form covering the inferior surface to the periphery. Diam., *5 inch. Mediterranean Sea. The shell has very much the appearance of a Rotella, being transversely flattened into a disk-like form. J. Italica, Issel, is a synonym; I figure two examples of it to show the young and half-grown states of the species (figs. 355, 356). DESMOULEFA. 65 N. PELLUCIDA, Risso. PI. 18, fig. 360.

Weinkauff considers this var. minor of N. neritea, but the coloration is decidedly different as well as the size being smaller. N. Kamixscur, Chemn. PI. 18, figs. 357, 358. Brown, with a white sutural and peripheral band, callosity rosy-brown. Last whorl enveloping a portion of the spire, which only shows three minute whorls, and has a sharp point. Black Sea. Genus DESMOULEA, Gray. Desmoulea is remarkable for its obtuse apex and solid growth, much resembling some species of Cassididz; when in fine con- dition, the shell is clothed with a velvety epidermis, but most cabinet specimens are denuded of this. The animal is unfortu- nately unknown, and therefore the systematic position of the genus remains somewhat uncertain—for, whilst some species connect closely with Nassa, the revolving sculpture, globose form, sunken suture and mouth of others are suggestive of Semicassis. D. ABBREVIATA, Gmelin. Pl. 18, fig. 361. Yellowish white, with chestnut-colored spots and strigations. Length, 1-1°5 inches. Cape of Good Hope.

The pertinence of this species, as well as of those which follow, to the group, is somewhat doubtful, as they have the form of Nassa, including its pyramidal spire. D. pyrAMIDALIS, A. Adams.

A singular species which unites the sculpture of Nassa with the mouth of Desmoulea—the latter even exaggerated in its characters. X Family TURBINELLID A. \ This group includes a few ponderous tropical species, allied in the characters of the mouth, and in general form and orna- mentation to the Peristerniine (see vol. iii, p. 79), on the one hand, whilst in size they approach the Volutide. The plications on the middle of the pillar are rather distant, narrow, high, and transverse, whilst in Fasciolariine they are situated lower, are not so prominent, and oblique in direction. The epidermis is frequently persistent. TURBINELLA. 67 The animal (of Vasum) is slow-moving, timid and inactive, shrinking quickly within the shell on the slightest alarm. The operculum is ovate, acute, with an apical nucleus; it is very thick, claw-like, and partially free at the hind part. The denti- tion resembles somewhat that of the Buccinidee, differing in the lateral teeth; it differs widely from the Nassidz, and quite as much from that of the Fasciolariine or Peristerniine.

I adopt Lamarck’s generic name in preference to that of Mazza, Klein, because the latter included several groups, and was only limited to its present signification by Messrs. H. and A. Adams,whilst the former author cites as his sole type a species which possesses the distinctive characters now assigned to the genus. The difference between the shells of Yurbinella and Vasum is not such as to indicate any differential characters in the animals (unfortunately that of Turbinella is unknown) and the separation of these genera is merely a matter of convenience * Conrad has formed a genus Mazzalina (uncharacterized), for a Claiborne fossil, which seems to have suggested to him the recent genus Mazza (= Turbinella). The type is, I believe, more nearly related to Lagena from which it does not appear to have any differential characters (see vol. iii, p. 225). 68 TURBINELLA. to the systematist. The dentition of Imbricaria, Schum., a group of Mitride, differs radically from the type of that family and approaches closely to Yurbinella—that is, if Troschel has cor- rectly identified the mollusk examined by him; but the species are so essentially Mitre in other characters that to separate them from that family would be very inexpedient. T. pynum, Linn... Pl. 19, figs: 1-3, 5=7. Whitish or yellowish white, under a thick, light olive epidermis ; sometimes irregularly sprinkled with chestnut-colored spots; interior of aperture and columella yellowish to orange-brown. Length, 4-7 inches. Ceylon. T. rapa, Gmel. (fig. 5), = gravis, Dillw., = clavata, Wagn., = napus, Lam. (fig. 3),is distinguished by most authors on account of its more swollen growth and absence of spots, but the distinction does not hold good, the shell becoming more swollen and less spotted with increase in size; like our Virginia Deer the spotted coat is a juvenile condition of which, however, traces sometimes remain, or rather recur, in the adult shell. I figure a very curious planorboid monstrosity (figs. 6, 7), existing in the Museum of the University of Ghent. The shankh or chank is the sacred shell of the Hindus, and the national emblem of the Kingdom of Travancore. The god Vishnu is represented as carrying a chank shell in one hand and a chakra in the other. The Hindus believe that unless they worshiped this shell at the commencement of every worship or prayer, their offerings would not be accepted. The first incarnation of Vishnu, called Machhavatar (which literally means transformation into a fish), was undertaken for destroying Shankhasura (the giant chank shell), in order to regain the Vedas, he having stolen them and taken refuge under the ocean. The fishery for these shells is principally carried on in the Gulf of Manaar, in the vicinity of Ceylon, and on the coast of Coromandel, at Travancore, Tuticorin, and other places, the shells being brought up by divers in about two or three fathoms of water. Those taken with the animal in, and called green chanks, TURBINELLA. 69 from having the epidermis on, are most in demand. The white chanks, or dead shells thrown upon the beach by strong tides, having lost their enamel, are scarcely worth the cost of freight to Caleutta. The number obtained varies considerably in differ- ent years, according to the weather and the success attending the divers. Frequently four or five millions of these shells are shipped in a year from the Gulf of Manaar. In some years the value of the rough shells, as imported into Madras and Calcutta, reaches ten to fifteen thousand pounds sterling. A few hundreds are occasionally imported into Calcutta from the Arabian and Persian Gulfs. The chank fishery of Ceylon at one time employed six hundred divers, and yielded a revenue to the island govern- ment of £4000 per annum for licenses. The fishery is now free. These shells are often used as oil vessels or lamps in Indian temples, for which purpose they are carved and sculptured or otherwise ornamented. A reversed chank is so highly prized for its rarity as sometimes to sell in Calcutta for its weight in gold, or at from forty to fifty pounds sterling. In Ceylon, also, the reversed variety is held sacred by the priests, who administer medicine by it. This shell, from its weight and smoothness, is used in Dacca for calendering or glazing cotton, and in Nepal for giving a polished surface to paper. The principal demand for these shells is for making bangles - or armlets and anklets, and the manufacture is still almost con- fined to Dacca. The shell is cut or sliced into segments of circles, or narrow rings of various sizes, by a rude semicircular saw, the hands and toes being both actively employed in the operation (Pl. 3, fig. 34). Some of these bangles, worn by the Hindoo women, are beautifully painted, gilded and ornamented with gems. The shell rings are coated inside with plaster to smooth the roughness. Filagree-bordered edges of plaster are also added ; patterns and devices of red, blue and gold are figured on them,and they are further ornamented with silver or gold tinsel, spangles, small colored glass beads, ete. The larger bracelets, formed of many segments, are made to open to admit the hand, by two spiral pins, which unscrew and let out the piece (Pl. 3, fig. 83). These bangles are not removed at death, and hence 70 TURBINELLA. there is a continual demand for them, many wearing several, both on the legs and arms.* In India, China and Siam the chank shell is highly prized, especially a sinistral variety found on the coasts of Tranquebar and.Ceylon, and made use of by the Cingalese in some of their most sacred rites. Such reversed shells are held in special ven- eration in China, where great prices are given for them. They are kept in the pagodas by the priests, and are not only employed by them on certain special occasions as the sacred vessels from which they administer medicine to the sick; but it is in one of these sinistrorsal turbinellas that the consecrated oil is kept with which the emperor is anointed at his coronation. These shells are often curiously ornamented with elaborate carvings. The tur- binella is so extensively employed in ornamental manufactures in the East Indies that upwards of four million shells have been exported in a single year from Ceylon to the ports of Calcutta and Madras; these are chiefly employed in making armlets and anklets, which are often highly ornamented and are known by the name of bangles. The mamillary apex of the shell is made into a button or bead; the latter are called krantahs, and neck- laces of these are so commonly worn by the Sepoys in the East India service as almost to be deemed a regular part of their uniform.+ T. ovorpEA, Keiner.

VASUM. 71 Domingo, and the West Indies is given as habitat in the “ Con- chylien Cabinet,” but the species does not occur in the Swift Collection, and I think there is no other authority for this locality. The young shell is so covered with nodules and revolv- ing ribs as to be readily mistaken for another species. The revolving sculpture disappears and the nodules become fewer and more prominent with advancing age. This and the next species do not fall completely within the generic characters of Turbinella; the sculpture and nodules indicate a transition to Vasum, but they have not the elaborate ornamentation of the latter genus—particularly its spinose fasciole. T. Fusus, Sowb. Pl. 20, fig. 9. White, covered with a thick, fibrous epidermis tufted in rows. Length, 7 inches. Habitat unknown. The tufting occurs upon the distant revolving riblets.

Reeve attempts to distinguish V. castus, Brod. (fig. 12), from the Bay of Caraccas, by its having broader furrows, larger tubercles and only four instead of five plaits on the columella, but these characters vary considerably in the numerous speci- mens before me. The fifth plait is merely an incipient one which sometimes occurs between the normal upper plait and the next one below it. The West Coast specimens which I have examined are all four-plaited, and this corresponds with Carpen- ter’s remark upon them in his ‘“‘ Mazatlan Catalogue.” I think that J. Crosseana, Souv. (fig. 19), described from a single specimen, the locality of which was doubtful, is probably only a worn individual of this species. V. RHINOCEROS, Gmelin. Pl. 21, figs. 13, 14.

The expansion of the posterior part of the aperture, that of the columellar callus, the more distant nodes on the shoulder of the body-whorl serve to distinguish this from the preceding species.

The shells of this family are conspicuous and showy, and many of them rare; like the Cyprzidz and Conide, the acqui- sition of fine collections is frequently deemed worthy the expenditure of much time and money, and information upon the classification and determination of the species is eagerly sought. The consequences of this state of things are a large number of so-called species erected out of mere individual variations and a succession of classifications, each vying with the other in com- plexity. Neither the anatomy of the animals nor the differences between the shells justify the numerous generic divisions which have been proposed, and I gladly follow one of the latest as well as the most judicious of systematists, Mr. H. Crosse, in reducing most of them to mere groups within the genus Voluta. H. and A. Adams included a classification of Volutide in their ‘ Genera of Recent Mollusca,” Vol. 1, 1853. They were shortly followed by Dr. J. E. Gray, in “ Zool. Proceedings,” 1855, “‘ Catalogue of the British Museum,” xxvii, 1855, and “ Guide to the Mollusca,” 1857. The latter was partially adopted, and partially adapted to their former system by Messrs. Adams, in the ‘‘ Appendix” to their work, published in 1858. Crosse’s arrangement of the Volutes was published in ‘‘ Journal de Conchyliologie,” 3 ser. vi, 105, 1866; and xi, 263, 1871. Finally, Mr. Wm. M. Gabb published a modified version of Dr. Gray’s system, including, however, the fossil genera, omitted by his predecessors. (Proc. Philad. Acad., 286, 1876.) 4 Two subfamilies have been made by Gray, Gill and others, based primarily upon differences in the lingual dentition. One of them, containing the genera Amoria and Volutimitra of Gray, 10 74 VOLUTIDA. is instituted upon the examination of the dentition of a single species in each of these genera. That of Amoria Turneri, Gray, has been supposed by some conchologists to be an error on the part of that very .able but exceedingly hasty and careless observer, as it appears to correspond very closely with that of a nudibranchiate mollusk, Favorinus albus, Alder and Hancock.* The dentition of Volutimitra Grenlandica is similar, but with the addition of lateral teeth. We are not willing to remove a number of tropical species heretofore classed in this genus along with this single boreal one, from the Mitridz to the Volutide, merely upon the evidence of the armature of this one species. The shell of Volutimitra has no intimate relationship with Voluta, but it is essentially a Mitrid. Gray ineluded a consid- erable number of species of Marginellide in his subfamily Volutimitrina, but these were excluded by H. and A. Adams. It remains to specify an entirely different type of dentition, as discovered by Dr. P. Fischer in Voluta musica, which approaches that of species of Marginellide. It is evident that such diversity in the few tongues examined must be fatal to the classification of the group upon this character, until we shall have determined the dentition of every species before assigning to it a definitive position. Fischer thus tabulates the dentition of the family, as far as known: { 1. Tooth tricuspid, with large lateral points. | Cymbium, Melo, Voluta, Lyria. CPI. 2, figs. 2, 3, 4, 7.) 1, Formula:0°1-°0. { 2. Tooth unicuspid, with concave base. Amoria. (PI. 2, fig. 5.) | 3. Tooth multicuspid, very transverse. lL Voluta musica.

Volutes are rarely collected with their animals, except when they are accidentally thrown ashore after a storm. They have therefore been said to live in the depths of the sea. The reason they are not found is that, like the Naticsz,they bury themselves under the surface as soon as the water falls and the sand is left * Morch, Jour. de Conch., xv, 241, 1867. VOLUTIDA, 15 dry by the tide; they are only to be procured by digging for them, or when a violent storm disturbs the sand and throws them on the beach.* The above rematk is tpon Australian species, but those of the southern extremity of South America are also found numerously in shallow water, feeding on Mytilus, etc.; nevertheless other species have been dredged from great depths, as V. papillosa at 1900 fathoms. The cavity of the nucleus in a cut specimen of the shell of V. vespertilio is neatly entirely filled with an amber-colored pellucid calcateous deposit; and the whole of the rest of the cavity is lined with a thick glossy deposit. In a cut specimen of V. Hebrea (the nucleus of which is destroyed) the cavity of the upper whorl is quite filled with a white glossy deposit, and a similar deposit lines the whole of the inner cavity of the shell.

Differs from Voluta in possessing an oper- culum, and in dentition. I am unable to follow Mr. Crosse in this separatiou from Voluta, for several reasons: 1st. The dentition of only a single species (V. musica) of the Volutes with numerous columellar plaits has been examined, and there are others, V. Hebrewa, for instance, which cannot be separated concho- logically from V. musica, but the dentition of which is unknown. 2d. The assumed type of dentition of Voluta rests upon the examina- tion of only three or four among the numerous species of the genus—it may differ widely in some of the others 3d. The presence of an operculum is proven in V. musica, but its absence is not proven in most of the Volutes, although we know it to be absent in several of them. The presence or absence of an operculum has but little value in the classification of some groups; indeed it is well developed or absent in the,same species occasionally, as in Volutharpa, etc. Ath. If we assume V. Hebrwa and J. virescens to be, with V. musica, Volutolyriz, what shall we do with the groups Harpula and Fulgoraria, which form the passage into the Volutes with few plaits ? 5th. If we adopt Voluta, Linn, or even the restricted Voluta of Gray, in either case V. musica is the type, and if a new name is required it is for those species the characters of which are different from V. musica. } LYRIA, Gray. Shell ovately fusiform, solid; spire acuminate; whorls longitudinally ribbed; aperture ovate, rather narrow; columella with numerous transverse plaits; outer lip simple, acute. Dentition, Pl. 2, fig. 7. The species are smaller than in Voluta, and Mitreform, connecting with the genus Mitra. MICROVOLUTA, Angas. Shell small, ovately fusiform, solid, smooth, shining; spire as long as the aperture, apex papillary; whorls simple; aperture narrowly ovate; columella with four strong transverse plaits, the anterior one the smallest; outer lip thin, simple, slightly contracted at the base; base rounded, spout-shaped, with a flexuous bend upwards towards the columella, which is a little thickened and reflected below the plaits. The above description is drawn up from the only known species, and probably many of its characters are of slight importance. The animal is unfortunately unknown. Fossil Genera. The following groups are enumerated by W. M. Gabb. They should probably all be considered as subgeneric under Voluta rather than as distinct genera, VOLUTIDA. rai VOLUTODERMA, Gabb. Shape similar to Fulgoraria, which it also resembles more or less in surface sculpture; apex not papillate; inner lip marked by from three to five well-marked folds, not very oblique, and of pretty uniform size. This is a group of shells characteristic of the cretaceous rocks and perhaps peculiar to them. They are all somewhat slender, and are marked by longitudinal ribs; the columella is always straight or nearly so, and the folds are as isolated and distinct as those of Turbinella. But the most strongly distinguishing character is the entire absence of the irregularly rounded mass at the apex of the shell, one of the best characters of Fulgoraria.

Cretaceous, Europe and India. Stoliczka refers this genus to Conidae, as he does also doubtfully Imbricaria and Cylindra, which he considers closely related. ‘The two latter are known to be in no way closely related to Conus, and Gosavia possesses every characteristic of a Volute; indeed I cannot separate it readily from such forms as V. musica. G. Inpica, Stol. Pl. 4, fig. 49. India. + Genus CYMBIUM, Klein. The animal is large compared to the size of the shell, when expanded. The foot partially covers the shell, which is sunk into its substance. There is no operculum. Ovoviviparous; the young when born being of a large size and covered with a shell with a large irregular callous apex. They leave the parent when they have attained a length of about an inch; the brood appear- ing to consist of four or five individuals. Adanson observes that the high winds of April cast the “yet” up in such vast quantities as sometimes to cover the shore; the natives of Senegal using them as food. The species are limited in distri- bution; one being an inhabitant of the Mediterranean Sea, the others of the West Coast of Africa. Cymbium is separated from Melo by its flat or slightly CYMBIUM. V9 channeled shoulder and want of coronal spines. When fresh, the epidermis is more or less covered by a thin glaze deposited by the enveloping mantle. Gray, Reeve and Sowerby have published monographs of this genus; the two latter with illustrations, For the figures of Cymbium, Melo and Voluta, in the present work, I am mainly indebted to Sowerby’s Thesaurus; they are usually much reduced in size, but the dimensions of the species are indicated in my text. C. PROBOSCIDALE, Lam. PI. 22, figs. 1-4. Yellowish brown, or light salmon-color ; epidermis very thin, brown, over which the mantle of the animal deposits a thin glaze; columellar plaits four in the adult, of which the last is small. Length, 1 inch to a foot or more. ; W. Coast of Africa. C. porcinum, Lam. (figs. 3,4) is the young of this species, having only two columellar plaits, and the ends of the shell not so attenuately contracted; it has generally been distinguished as a species with some doubt, but the specimens before me afford good evidence of the gradual evolution of proboscidale from por- cinum. Between the glaze and the epidermis particles of sand and even small organie bodies are frequently imprisoned ; the former giving the surface a minutely pustulate appearance. C. RUBIGINOSUM, Swains. PI. 22, fig. 6. There is some little difference of form between this and the last species, but I scarcely think them distinct. It was referred to Australia by Sowerby,and misunderstood and made a synonym of C. cymbium (not of Linn) by Dr, Gray = C. cistwm, Lam. Its true locality is N. W. Coast of Africa. Length, 4°5 inches. C. cistum, Lam. PI. 22, figs. 5, 7, 8. Shell light yellowish brown, elegantly marbled with chestnut. Length, 3-5 inches, W. Africa. Gray and others have referred C. cymbium, L., to this species, but the evidence given by Mr. Reeve that the true C. cymbium = (. proboscidale is pretty conclusive.* C. gracile, Brod. (figs. 5, 8), appears to be a form of this shell. * Ann. Mag. N. Hist., 3d ser. vii, 271. \ 80 MELO. C. Nepruni, Gmel. Pl. 22, figs. 9-12; Pl.1, fig. 3. Yellowish or reddish brown. Length, 6-10 inches. W. Africa. C. Tritonis, Brod. (fig. 10), is a synonym. The shell when young and in good condition, is frequently mottled with lighter and darker brown, and this color-variety has received the name of C. Navicula,Gmel. C. patulum, Brod. (fig. 11}, is another synonym. I figure, actual size,a quite young individual, with protruding spire (fig. 12) which afterwards becomes immersed in the succeeding whorls. C. ona, Linn. Pl. 22, fig. 13. Pale fulvous. Columella two-plaited. Length, 3°5—5 inches. Southern Spanish shores of the Mediterranean, N. W. Africa, Portugal, Canaries. A Genus MELO, Humphrey. The apex of the shell is spiral, regular, very different from the shapeless apex of Cymbium. The distribution of Melo is exclu- sively tropical and exotic, ranging from the Indian Ocean to Australia. Messrs, Adams state that the animal of this genus, like Cymbium,is ovoviviparous, the young ones being arranged in the oviduct of the female in a long string, without egg-shells. * Sptre covered or enclosed, unarmed. M. Inpica, Gmelin. PI. 23, fig. 14. Lemon-yellow to orange-color, with two or three revolving zones of tessellated spots; sometimes without spots when large.

PI. 23, figs. 15, 16. Yellowish or orange, under a light olive epidermis, with or without two or three revolving zones of brown tessellations. Length, 6 inches. Indian Ocean. The species of coronated Melos are very hard to separate, and MELO. 81 in fact, the number and direction of the spines vary so in differ- ent species that the distinction appears very arbitrary. * * * Spire exposed, not produced, spines ercet, spreading. M. Aruiopica, Linn. PI. 23, figs. 17-21. Yellowish or orange; generally maculated and _ tessellated with chestnut, usually in revolving zones. Length, 6-12 inches. Indian Ocean, Manilla, Japan. In deference to the opinion of the British conchologists, the following ‘‘species”’ may retain their names as stages of variation in the form, coloration and development of spines. It is easy to point out from the numerous excellent illustrations given by Reeve and Sowerby, how these authors differ in estimating these so-called species, and how even some of their figures refute their arguments for distinctness. Var. REGIA, Schubert. Fig. 18, Yellowish brown, with zones of white blotches. Var. NAuTICA, Linn. PI. 23, fig. 19. Spines close-set, converging towards the apex (also towards M. tessellata, very decidedly). Length, 6-8 inches. Var. Broperien, Gray. PI. 23, figs. 20-21. Spines very numerous, small. Length, 8—14 inches. M. piapeMA, Lam. PI. 23, figs. 22-28. Variable in proportions but generally more narrow than WZ. Aithiopica; spines few and long. Yellowish, marked with chestnut, frequently forming two: interrupted zones connected by irregular or zigzag markings. Epidermis thin, light olive. Length, 6-13 inches. Indian Ocean; Australia. Its narrower coronal, and the few long spines composing it are the best distinctive characters from M. Athiopica. As in that species I include here as varieties, several forms which have been heretofore considered distinct. M. armata, Lam. (figs. 24, 25), is a synonym. Var. DUCALIS, Lam. This, and its synonym M. umbilicata, Brod. (fig. 26), are more 11 82 VOLUTA. elaborately painted than the type, the inter-zonal markings form- ing an elaborate network of chestnut-brown veins. Moreton Bay, Australia. I am unable to separate from this variety the shell described by Dr. J. E. Gray as M. Georgine. Mr. Reeve speaks in a knowing manner of “a separate «system of characters in JM. ducale and M. Georgine,” distinguishing them from diadema, but he neglects to point out these distinctions. Var. Mittonis, Gray. Fig. 28. Shell more cylindrical, consequently showing more of the Spire. Swan River, Australia. t Genus VOLUTA, Linn. The animal is essentially like those of Cymbium and Melo, but the mantle is not usually so greatly expanded, nor is the foot proportionally so large. This genus is oviparous, at least the South American species are so, and M. Duhant-Cilly has given us some interesting par- ticulars concerning them.* He noticed the Volutes in clear shallow water in Magellan’s Straits, and, with the aid of natives, procured specimens—which nearly all grasped dead shells of Venus exalbida,a common bivalve of that locality. Upon ex- amining these shells they were found to contain within the cavity of one of the valves, a round, slightly convex membrane, com- parable for size and transparency with a watch-glass. The e contents appeared to be merely a milky fluid in some cases, but in others, the egg having advanced further in development, three or four small, but perfectly formed Volutes could be seen swim- ming in the fluid, which had become transparent. D’Orbigny also + collected large numbers of these eggs,and in the month of February saw the young Volutes, four of five in number, in each. The containing membrane, which becomes corneous, he describes as 80 to 100 millimetres in length, more than half the size of the animal which lays it, and he conjectures that it expands after coming into contact with the water. * Revue Zoologique, 167, 1840. + Voy. Am. Mérid., 424. VOLUTA. 83 Voluta of Linneeus, Lamarck, and other old authors, com- prised many species of other genera, but in restricting it more and more, until the advanced school of conchologists have left to it but a couple of species, the citation of Linneeus as its author has generally been retained. Mr. H. Crosse has, however, eliminated from the genus thus restricted, the V. musica, which is the first actual Voluta in Linnzeus’ list (after a crowd of Auricule, Columbelle, Marginelle, Mitrids). In compensation, he has reduced the numerous genera of H. and A. Adams, and Gray, to sections, retaining Voluta in something like the same comprehensive sense as that in which we use Helix, Fissurella, Pleurotoma and other old generic names. These “ sections ”’ are rather circumscribed geographically, yet the range of the entire genus is very great, including the Indian Ocean, Japan, Alaska, Australia, Eastern Polynesia, Atlantic coasts of Southern South America, to West Indies, Southern Africa, etc. No species exists in the seas of Europe, although they were numerous during the tertiary epoch; V. abyssicola, an African species, is the sole surviving representative of the group to which most of these small tertiary species belonged. Australia is the metropolis of the Volutes, and, as M. Crosse remarks, a triangle the res- pective points of which shall include Ceylon, Japan and New Zealand will cover the habitats of about 80 per cent. of the Species. Sect. 1. Voluta (typical), Gray. Longitudinally plicate, plicze becoming prominent on the shoulder, columella with four or five principal plaits, and several smaller ones. Operculum (of V. musica) fusoid, narrowly elongated, with terminal nucleus. V. musica, Linn. PI. 24, figs. 29-34, 38. Color generally pale yellowish or brownish, punctate, strigate and clouded with chestnut and other colors, with three revolving, more or less distinct bands of distant, parallel, fuscous lines, crossed by strigations; these bands are bordered by a row of dark spots, and the space between these rows is finely punctate with chestnut; outer lip dark chocolate, or chestnut-spotted. Length, 2—4 inches. West Indies. 84 HARPULA. The coloration varies greatly, as does also the degree of de- velopment of the plications, causing Lamarck and others, before this great variability became known, to describe different forms of the species under distinct specific names. These are V. thiarella, Lam. (fig. 31);V.G@uinaica, Lam. (fig. 32) ; V.carneolata, Lam.; V. levigata, Lam.; V. sulcata, Lam. (fig. 33); and V. polypleura, Crosse (fig. 34) ; the latter being the most distinctive of these varietal forms. I add a figure of the animal, with operculum (fig. 38); the dentition is also illustrated (Pl. 2, fig. 6). V. VIRESCENS, Solander. Pl. 24, figs. 35, 36. Light chestnut or ash color, with distant white bands; fre- quently numerous punctations of dark chestnut color are scattered over the surface ; outer lip with dark spots. Length, 2°5 inches. West Coast of Africa. V. pusio, Swainson (fig. 36), is a short form of this species, the surface in a worn condition. V. Hepraa, Linn. PI. 24, figs. 37, 40. Ovate, thick, pale fulvous with undulated angular vein-like lines of chocolate color, and sometimes interrupted bands of the same. Length, 3°5—4°5 inches. West Coast of Africa. Brazil (Nagely !) Var. TURBINATA, Kiener. Fig. 40. Darker reddish brown, without the hieroglyphic markings of the type-form. Sect. 2. Harpula, Swains. Shell oval-conic, spire with a papilliform but small summit ; columella with larger plaits below, and additional smaller ones above, but less numerous than in the preceding section ; exterior lip thickened within, sharp without. V.INTERPUNCTA, Martyn. Pl. 24, fig. 39. Flesh-color with numerous revolving series of chestnut linear spots, and frequently, under them, two or three series of revoly- - ing much larger and paler spots,sometimes also with longitudinal chestnut streaks. Length, 2°5--3°5 inches. Ceylon ; Indian Ocean. <= FULGORARIA. 85 Reeve says, “I quite agree with Mr. Sowerby in the propriety of abandoning the (earlier Linnean) name Lapponica given to this species, indicating a country and climate in which such a mollusk could not by any possibility exist. Instead of inhabit- ing the Arctic shores of Lapland, it is a native of the seas of tropical India. The error did not, however, originate with Linneus. The species was known before his time to Dutch naturalists, as the Lapphoorn or Lapphoren, signifying the Flap- Ear or Dog’s-Ear Shell. This seems to have been corrupted into Ailée Laponne, Alata Lapponica, Voluta Lapponica,and Meuschen and Rumphius compounded the name Laplandsche Lapphoorn. It only remains a matter of wonder that, whilst Seba described the Species as an exotic shell from India, the error should have remained so long unexplained.” V. vExitLuM, Lam. PI. 31, fig. 153. Flesh-color, with distant orange revolving bands, and some- times narrower intermediate ones; occasionally the surface is longitudinally clouded with orange in addition to the above specific pattern. Length, 3-4 inches. Indian Ocean. Sect. 3. Fulgoraria, Schumacher. Shell oblong-fusiform ; spire moderately elongated, terminated by a papillary summit with the apex lateral,instead of central and vertical as usual in spiral shells; surface plicate longitudin- ally, crossed by engraved revolving lines; columellar plaits six or seven, or more; lip thickened within, its margin slightly crenulate. The swollen bead-like apex, the initial whorl of which is lateral, is a curious feature of this group, which may indicate some important difference in the development of the mollusk—which is so far unknown to scienee. V. RUPESTRIS, Gmelin. PI. 24, figs. 41, 42. Yellowish flesh-color, with zigzagged longitudinal chestnut lines ; interior flesh-color. Length, 3-6 inches. China, Japan. V. Hamillet, Crosse (fig. 41), is described from a large, yet immature specimen of V. rupestris, as indicated by Lischke in his work on the Japanese Mollusca. 86 VESPERTILIO. Sect. 4. Vespertilio, Klein. Shell oval-oblong, more or less ventricose. Spire terminated by a regularly spiral summit, papilliform, but having an appar- ently crenulated nucleus, caused by the presence of numerous little tubercles, more or less apparent. Columella four-plaited. V. VESPERTILIO, Linn. Pl. 25, figs. 43-49, 52. Yellowish flesh-color, covered by an irregular network of chestnut brown, which is occasionally confluent into broad angulated blotches. Length, 3-5 inches. Philippines Moluccas. One of the most variable species in form, development of spines and folds, and coloring. I figure V. pellis-serpentis, Lam. (fig. 46), V. mitis, Lam. (fig. 49), V. serpentina, Lam. (fig. 47), and V. lineolata, Kuster (fig. 52). Also a reversed specimen (fig. 45). V. PULCHRA, Sowerby. PI. 25, figs. 50, 51. Pale flesh-color, with white specks, and small chestnut dots, irregularly disposed in three bands. Length, 2°5-3 inches. N. and N. #. Australia. V. Wisemant, Brazier (fig. 51), is acknowledged by its author to be a variety only, of V. pulchra. V.nivosa, Lam. PI. 25, fig. 53. Grayish flesh-color, sprinkled with small white specks; with two revolving bands, consisting of longitudinal, subparallel, more or less interrupted chestnut-colored lines ; columella and aperture saffron-yellow. Length, 2°5-3°5 inches. W. Coast of Australia. V. Nogrist, Gray. Pl. 25, fig. 55. Grayish brown, flecked with white and less numerously with brown; there are two interrupted bands of darker color, here and there marked with longitudinal lines; the shoulder also is darker and strigate with brown ; aperture light chocolate within. Length, 2°5-3 inches. . W. Coast of Australia. The markings on the bands frequently assume a somewhat irregular checker-board appearance. Dr. Gray described this species in 1838, and Sowerby (probably finding a specimen AULIOA. 87 labeled, but without authority for the name attached) redescribed it under the same name in 1844; since then, the species has been quoted in all the monographs as well as in Crosse’s list as Sowerby’s, and Gray himself, forgetting that he had described it, quotes it as of Sowerby in his British Museum monograph. V. Sopnim, Gray. Pl. 25, fig. 57. Yellowish white, with two interrupted darker bands, which are bordered on either side by a line of chestnut spots. Length, 2°5 inches. W. Coast of Australia. Perhaps a variety of V. Norrisit. V. rutina, Brod. Pl. 25, figs. 56, 54. Shell variegated, whitish and saffron-red, forming subtrigonal blotches, and irregular veins, and usually indicating obscurely by their confluence and broadening two revolving bands ; some- times slightly tuberculate on the shoulder ; aperture salmon-red within. Length, 3-3°5 inches. NV. H. Coast of Australia ; New Guinea. Var. INNEXA, Reeve. Fig. 54. Lighter colored, tuberculate. Louisiade Islands, near New Guinea. V. prperiTa, Sowb. Pl. 26, fig. 60; Pl. 27, figs. 75, 76, 78. Finely nettedand peppered with orange-red on a whitish ground, with three interrupted bands of large orange-red spots, and columella and interior of aperture same tint. Length, 2°5-3 inches. Solomon Is., Woodlark Isl., near New Guinea. V. Rickert, Crosse (fig. 15), V. Macgillivrayi, Cox (fig. 76), and V. Ceraunia, Crosse (fig. 78), are all mere color-varieties of this species. Sect. 5. Aulica, H. and A. Adams. Agreeing with the preceding section in general form and principal characters, the summit of the spire differs in having a completely smooth instead of a tuberculated surface. VY. aunica, Sowb. Pl. 26, figs. 61, 62. Flesh-colored, with large salmon-colored clouds, sometimes 88 AULICA. forming three very broad, interrupted bands, sometimes con- fluent, irregularly covering most of the surface; interior flesh- yellow. Columellar plaits oblique. Length, 3°5—4°5 inches. Sooloo Is. V. Catucarti®, Reeve, PI. 27, fig. 79. Orange and flesh-white, the former making an irregular zigzag or netted pattern, with three bands of dark chocolate spots. Length, 3°5 inches. Habitat unknown. The figure of the type resembles V. piperita except in its — smooth apex, rather more closely than V. aulica, with which M. Crosse compares it. V. Desuayesi, Reeve. Pl. 26, fig. 63. White or pink, with orange-red irregular clouded markings, and a central band whereon they do not appear ; aperture orange- color; columellar plaits much stronger than in V. aulica, and nearly transverse. Length, 3-4 inches. New Caledonia. V. Rossrntana, Bernardi. Pl. 27, fig. 64. Flesh-color, with longitudinal angular markings of chestnut- brown. Length, 7 inches. New Caledonia. The spire is more elevated, the spines less developed than in V. imperialis; the plaits on the columella are five in number (four in imperialis) and more transverse, the outer lip more expanded; yet it may be only an extreme variety of that species. V.LuTEostoMA, Desh. PI. 25, fig. 58. Shell resembling the last species, but smaller, and having four plaits only on the columella—which, however, are transverse like it, and not oblique as in V, imperialis, The interior of the aperture has the orange-coloring of V. Rossiniana. Length, 2°5 inches. Habitat unknown. Certainly very closely allied to the preceding species. V. IMPERIALIS, Lam. PI. 26, fig, 65.

Philippine Islands.—Cuming. V. punoTaTa, Swains. PI, 24, fig. 80. Pale fulvous, with numerous small light chestnut dots, some- times confluent into larger spots, forming interrupted bands. Length, 3 inches. Kastern Australia. The figures in Swainson, Sowerby and Reeve represent an immature individual, the only one known until ten years ago, when the adult was first figured by Dr. Cox. V. Harcreavest, Angas. PI. 27, fig. 82. Reddish brown, with an indication of two darker bands, ornamented with numerous, scattered longitudinal and some- what angular blotches of white; columella and border of lip tinged with orange, aperture flesh-color within. Length, 3 inches. Habitat unknown. The specimen described is so far unique. V. BEDNALLI, Brazier. Pl. 26, fig. 66. Whitish, with four narrow chestnut-colored revolving bands, which are connected by angular longitudinal chestnut mark- ings; aperture white within. Length, 3°3 inches. Port Darwin, Torres Sts., N. Australia. V.scapHa, Gmelin. PI. 26, fig. 68. Shell ponderous, smooth, yellowish flesh-color, with zigzag longitudinal chestnut markings, sometimes widening into series of irregular spots, forming two interrupted bands. Length, 3°5-5 inches. Singapore, on the reefs.—Cuming. V. Maanirica, Lam. Pl. 26, fig. 70. Rather thin; pale fulvous, with three broad orange-chestnut bands marked with white and fuscous angular spots, inter- mediate surface reticulated with pale orange angular lines ; columella and interior orange or salmon-color. Length, 6-8 inches, or even a foot. East Coast of Australia. One of the largest species of the genus; it is found half- 12 90 AULICA. burying itself amongst weed and ooze on sandy and muddy flats beyond tide-mark. V. Junonia, Chemn. PI. 26, fig. 67. Pale yellowish or whitish, with numerous rather large rounded square chestnut-colored spots arranged in revolving series ; interior flesh-white. Length, 3°5—4°5 inches. East and West Coasts of Florida. It is an inhabitant of deep water, and is somewhat rarely obtained and highly prized by collectors. Specimens have been sold as high as two hundred dollars, but of late years the value has greatly decreased in consequence of increased supply. V. pusiA, Brod. Pl. 27, figs. 77, 81. The spire is proportionally longer, the spots more sharply square than in V. Junonia, the longitudinal ribs, which in that species are barely visible upon the first whorl below the embryo- nal apex, show traces of their existence as far as or even including the body-whorl. V. Junonia is spirally seulptured towards the base of the body-whorl, whilst in this species the sculpture covers the entire whorl. Length, 3-6 inches. Caribbean Sea, off the Southern and Western Coasts of Florida. This shell was first figured as Pusus tessellatus by Schubert and Wagner, and subsequently described by Broderip as V. dubia (fig. 81), but the shell was only known in an immature and faded condition until Dr. Dohrn in 1879 gave a full description with figures of what he supposes to be the adult shells. My impression is that it is merely an elongated variety of V. Junonia, but the question of identity can only be settled satisfactorily when a larger mass of material shall be at the disposal of naturalists, than is now available. V. Kaurn, Dunker., Pl. 26, fig. 69. All the whorls except the embryonal apex are slightly plicate below the sutures; last whorl obtusely angular; pale yellowish red,marbled irregularly with a darker tint. Length, 2°25 inches. New Zealand ? Probably not mature; the type is the only specimen known. AULICA. 91 V. FLAVICANS, Gmelin. PI. 26, fig. 71; Pl. 27, fig. 84. Yellowish gray, fasciculated with brown beneath the sutures ; surface marbled, strigated and reticulated with brown. Length, 3-3°75 inches. N. Australia. V. signifer, Brod., is an elongated flavicans, with the lip not quite mature. V. Tissotiana, Crosse (fig. 84), is also a variety. V. EXOPTANDA, Sowb. PI. 26, fig. 72. Pale rose-orange, densely promiscuously painted throughout with sharply waved fine chestnut-red lines; columella and interior of shell orange-color. Length, 4 inches. Port Elliott and Port Lincoln, Australia. Is V. Hargreavesi, Angas (Pl. 21, fig. 82), a aha a variety of this species ? V. Austratim, Cox. Pl. 26, fig. 73. Reddish orange, with dark chestnut undulated longitudinal markings. Length, 2°5 inches. Bass Straits, Australia. The sutures are said to be vitrified, a character of the next group, Amoria ; from which it differs in having only four colu- mellar plaits. Appears to be rather too closely allied to V. exoptanda. Mr. Brazier considers it a variety of V. undulata, Lam. V. Gray, Crosse. Pl. 26, fig. 74. Yellowish, with zigzag longitudinal brown lines, increased in thickness so as to indicate three interrupted revolving bands. Length, 5°5 inches. Northwest Coast of Australia. Described by Gray as V. Maria-Emma, and the name very properly changed by Crosse because not binomial; and if per- mitted to stand in this case,some Spaniard having baptismal names enough to fill half a page might have them all immortal- ized in a single species. This species is, so to speak, intermediate between Aulica and Amoria, for to the nucleus characteristic of the first group it unites the system of coloration and suture of the second. 92 AMORIA. V. Kina, Cox. Pl. 27, fig. 86. Yellowish flesh-color, with a very few slightly apparent darker zigzag lines. Length, 3 inches. King’s Isl., Bass Straits, Australia. Supposed by some conchologists to be a variety of V. undulata, Lam., but appears to differ in its proportions, in the convexity of the spire-whorls, in having only four columellar plaits, ete. V. MARMORATA, Swainson. PI. 28, fig. 89. Slightly coronate; yellowish flesh-color, with irregular striga- tions and angular, flexuous, longitudinal brown lines, faintly indicating two revolving bands. Length, 4—5 inches. East Coast of Australia. Sect. 6. Amoria, Gray. Shell fusiform, smooth and polished; spire conical, with a small, more or less pointed nucleus; sutures slightly callous ; columella with five oblique, more or less developed plaits. V. unpuLATA, Lam. PI. 28, figs. 88, 87. Pale fulvous, with undulated narrow chestnut, longitudinal lines. Length, 3-3°5 inches. E,W. and 8. Australia, Tasmania. V. Angasi, Sowb. (fig. 87), is only a form of undulata with shorter spire. Mr. Brazier thinks that V. Sclateri,V. Kingi, and V. Australiz of Cox, are all mere varieties of this species. V. SciaTert, Cox. Pl. 27, fig. 83. Pure white, without markings. Length, 3 inches. Tasmania. Perhaps a variety of V. undulata, Lam. V. Turneri, Gray. Pl. 27, fig. 85; Pl. 30, fig. 123. Whitish or flesh-yellow, with longitudinal, somewhat waved narrow chestnut lines; yellowish or light chocolate within the aperture. N. H. Australia; W. Australia (V. Eiliott). V. Ellioti, Sowb. (fig. 123), is not entitled to distinction even as a variety, and, together with several varietal names given by Gray himself, must merge in the synonymy. AMORIA. 93 V. vonvaA, Gmelin. PI. 28, fig. 90. Whitish, with three faint yellowish bands, upon which are a few longitudinal, pale orange strigations; yellowish brown or coffee-colored within. Length, 3 inches. W. Australia ; abundant. Certainly very close to V. Turneri. The species was rede- scribed by Gray as V. pallida, but he subsequently united it with V. Turneri. The patterns of coloration of the two specics are different, and I find no connecting links. V. MACULATA, Swains. PI. 25, fig. 59. Obconic, marked with chocolate spots forming two interrupted bands on an orange surface; aperture orange within. Length, 2°25 inches. East Australia. The coloring is more vivid than in V. volva, and the spire is shorter, but the species may be only a variety of that shell, to which it bears the same relation that V. zebra does to V. Turner. V. zepra, Leach. PI. 28, fig. 91. White or yellowish, with close-set, narrow somewhat waved longitudinal chestnut streaks; very pale yellow or pink within the aperture. Length, 1°5-1°75 inches. Hast Coast of Australia. Resembling V. Turneri in coloration, but differing in its smaller size, and short, obconic form. Y. Loroisr, Valenciennes. PI. 28, fig. 92. Light pinkish, with brown zebra-like stripes, columellar plaits almost obsolete. Length, 3 inches. Habitat unknown. Described from a worn specimen in the Paris Museum. It belongs to the same group as J. zebra and Turneri, and may be an overgrown specimen of the former. V. CANALICULATA, McCoy. PI. 28, fig. 95. Whitish, with five revolving rows of chestnut-colored oblong spots; suture channeled. Length, 1°75 inches. EH. Australia. V. Harfordi, Cox, described a few months later, is identical. 94 ALCITHOER. V. RETICULATA, Reeve. Pl. 28, fig. 93. Light fulvous, triangularly marked with chestnut, forming three bands on the body-whorl ; yellowish within. Length, 3—4 inches. W. Australia. V. PRETEXTA, Reeve. Pl. 28, figs. 94, 96. Pale fulvous, finely reticulated with chestnut, forming triangu- lar spots, and two darker bands. Length, 1°5—2 inches. North Australia. Bears somewhat the same relation to V. reticulata that zebra does to Turneri. V. reticulata, Sowb. (fig. 96), is only a well- grown specimen of V. pretexta; although Sowerby afterwards renamed it V. Reevet. Sect. 7. Alcithoe, H. and A. Adams. Shell oval-fusiform, spire elongated, terminated by a_ papilli- form summit; aperture oval-elongated, inner lip covered by a callous deposit, outer lip expanded and more or less reflected ; columella with four, and more rarely five to seven oblique plice. VY. Pacirica, Solander. Pl. 28, figs. 97-99. Yellowish, with zigzag longitudinal chestnut markings, and frequently four interrupted revolving bands. Length, 3°5—4°5 inches. New Zealand. The specimens vary much in the development of the shoulder- angle and tubercles, both being obsolete in some species. VJ. Susus, Quoy (fig. 98), is the immature shell. Var. GRACILIS, Swn. (fig. 99), has been distinguished principally by its much smaller size, V. Krevster&, Angas. Pl. 30, fig. 124. Resembles V. Pacifica, but has a longer spire, is narrower, and differs in the painting of orange-brown maculations forming the three bands. Length, 2 inches. V. AMERICANA, Reeve. Pl. 28, figs. 100, 101. Yellowish white, faintly banded and reticulated with orange- brown. Length, 1°75 inches. So. Australia. Brazil. ALCITHOR. 95 Only a single specimen known. V. Cleryana, Petit (fig. 101), is the young of it. VY. restiva, Lam. PI. 30, fig. 125. Rosy white, clouded with orange-red, with chestnut spots and bands formed of series of longitudinal flexuous chestnut striga- tions. There are three prominent oblique plaits at the lower part of the columella, and above them a number of oblique rugosities. Length, 4-5 inches. Hast Africa. One of the rarest of Volutes. The exact locality is unknown. D’Orbigny speaks of collecting it on the Patagonian coast, but he doubtless refers to V. Magellanica. V. ArricANaA, Reeve. Pl. 30, fig. 127. Orange-brown, with sparse hieroglyphic brown markings disposed in bands ; upper part of columella black. Length, 2°5 inches. Hi. Africa. The type, which formed part of the Cuming collection, is not in good condition, so that the pattern of painting is obscure. It is closely related to V. festiva, but appears to differ in its greater proportional width and short spire. V. MreGAsPIRA, Sowb. PI. 28, fig. 102; Pl. 30, fig. 132. Reddish flesh-color, longitudinally marked with zigzag chestnut streaks, sometimes forming three obscure bands. ° Length, 4 inches. Japan. An elegant smooth species; rather thin, with the first volution of the papillary apex lateral instead of terminal—a character Shared by some of the following species. The animal is a common article of food in Japan, yet the shell is rather rare in collections. V. lyriformis, Kiener (not Swains.), is apparently a variety of this species, although Mr. Crosse has recently characterized it under the name of V. Prevostiana (fig. 132). V. FUSIFORMIS, Swainson. PI. 28, fig. 103. Fulvous or flesh-colored, with irregular, zigzag, longitudinal chestnut markings. Length, 6—7 inches. Tasmania ; So. Australia. 96 ALCITHOE. V. FULGETRUM, Sowb. Pl. 28, figs. 104, 105. Yellowish flesh-color, with broad, undulated, longitudinal, dark chestnut or chocolate streaks. Length, 4-5-5 inches. So. Australia. The spire is shorter, the shell is more shouldered, the painting is usually much broader than in V. fusiformis. Sometimes the markings include a faint, closer reticulation besides the above more prominent features, and occasionally bands are indicated. V. fulgetrum, in fact, is intermediate between V. fusiformis and V. papillosa, and very probably the three are merely diverse forms of one species. V. PAPILLOSA, Swn. PI. 28, fig. 106, Very finely reticulated longitudinally with chestnut color on an orange-brown surface, with interrupted bands. Length, 4-5 inches. So. Australia ; N. Tasmania. Kiener unites, apparently, this species and fusiformis in his V. Sowerbyi. Specimens were brought up by the dredge from 1,900 fathoms, 25 miles off the coast of New South Wales (Brazier). Var. MacquarieEnsis, Petterd. Shell same form and size as typical, but of a more or less intense yellow-color throughout, without any markings. It is not figured. V. THatcHerRI, McCoy. PI. 30, fig. 126. Pinkish white, with narrow chestnut reticulations, Length, 4-5 inches. Bampton Reef, near N. W. Coast of New Caledonia. Appears to be very closely related to V. Pacifica, Sol. V. Roapnicut#, McCoy. PI. 30, fig. 128. Pale brownish creamy white, with acutely angular zigzag, longitudinal, sparse markings of rich, raw-sienna brown. Length, 6-4 inches. So. Coast of Victoria, Australia. CYMBIOLA. 97 Sect. 8. Cymbiola, Swainson. Shell oval, thin, recalling the form of Cymbium. Spire more or less elongated, terminated by a slightly irregular, papilliform summit. Aperture large, the columellar side covered with a slight coat of enamel; columella usually with four oblique plications; outer lip sharp, occasionally slightly expanded. An American, and principally Antarctic group. V. ancryuA, Solander. PI. 29, fig. 110. Yellowish, with faded chestnut, longitudinal, irregular streaks. Length, 5—6°5 inches. Coast of Patagonia. This is the V. Magellanica, of Sowerby, Kiener and Gould, who describe the latter species as ancilla; the latter has an excellent figure of the animal. V. Srearnsil, Dall. Pl. 30, fig. 130. Livid purple, more or less obscured by an ashy white outer layer; exterior smooth, but not polished; aperture white and livid purple, with a dash of brighter purple at the posterior notch, and on the anterior portion of the callus. Length, 4:13 inches. Alaska ; living from stomach of cod, dead on beach. Very closely related to V. ancilla. V. Macetianica, Lam. PI. 29, figs. 107, 108. Yellowish white, generally irregularly painted with longitu- dinal, zigzag, brown streaks, sometimes interruptedly banded. Length, 5—6 inches. Patagonia. Var. TUBERCULATA, Swains. Whorls with a more pronounced, tuberculate shoulder. A wider species than V. ancilla but may possibly be a mere variety of it. V. Becxi, Brod. Pl. 29, fig. 109. Yellowish, with chestnut-colored, undulated, longitudinal streaks. Length, 11 to 14 inches. Habitat unknown. The Philadelphia Academy possesses a specimen of the largest 18 98 VOLUTELLA, PSEPH A. dimension given above. Although the habitat of the species is not known, it is very probably Patagonia. V. Brasitiana, Solander. Pl. 29, figs. 113, 115, 111; Pl. 30, fig. 131. Ventricose, with depressed conicai spire; brownish yellow, without markings. Length, 4-6 inches. So. America, from mouth of Rio de la Plata to Patagonia. V. Ferussact, Donovan (fig. 131), is almost certainly a worn specimen of this species. I havea shell before me, precisely the same shape, but with the tubercles slightly indicated on the shoulder. V. rudis, Gray (fig. 111), is usually considered a synonym of Ferussaci; Gray’s figure represents a shell in very bad condition. The specimen figured in the Thesaurus corre- sponds so little with the description as to indicate a very vivid imagination on the part of the colorist of that work. Sect. 9. Volutella, d'Orbigny. Shell smooth, subcylindrical, with angulated whorls; spire acuminated, polished, and entirely covered by an enamel deposit, obliterating the suture-line more or less entirely ; columella with three oblique plaits; lip sharp, not reflected. The development of a lobe of the mantle to cover the spire is a peculiarity in this animal not shared by the other species of the genus. V. ANGULATA, Swainson. PI. 29, figs. 112, 121. Pale yellowish; with longitudinal irregular chestnut lines. Length, 4—6 inches. Mouth of Rio de la Plata to Patagonia. The enamel deposit frequently projects above the spire into a beak (fig. 112), but is usually broken off in cabinet specimens. Sect 10. Psephza, Crosse. Shell oblong-fusiform, very finely transversely striated and furnished with longitudinal ribs, disappearing towards the middle of the last whorl. Nucleus? Columella furnished with two principal plicee, above which there are two or three minute ones hardly visible; it presents also this peculiarity (in the adult shell), that these plicz are situated so far within as to be invisible when the shell is placed right in face of the observer. AUSOBA. 99 Internal margin strongly callous ; external lip obtuse and thick- ened. V. concinnA, Brod. PI. 29, fig. 114. Yellowish brown, with close-set, undulated, longitudinal chestnut lines. Length, 4-5 inches. Japan. At first sight this shell might appear to be related to V. rupestris, from the same locality, but it differs in several respects, and particularly in the character of the plice. Sect. 11. Ausoba, H. and A. Adaws. Spire short and obtuse, terminated by a papilliform summit ; last whorl coronated. V. cymBioLA (Chemn.), Sowb. PI. 29, figs. 118, 119. Pale yellowish gray clouded with a darker tint, and punctate with chestnut ; aperture light chocolate. Length, 3 inches. Moluccas. The name was changed by Kiener to V. coronata because cymbiola had already been used by Lamarck for another species —an error, as Lamarck had not used the name at all. V. corona, Chemn. (fig. 119),is only known by the figure of a juvenile shell in that author, copied by Sowerby in his Thesaurus. Mr. Crosse believes it to be distinct, but I cannot agree to this, as it appears to me to be a faded young cymbiola. The nucleus is supposed to be proportionally much larger, but it is really not larger than in Kiener’s figure of V. coronata. Sowerby says that corona having, besides the four principal plicze, several smaller ones above them, is a character not shared by cymbiola, yet a charac- teristic specimen of the latter, before me, has two very distinct smaller plaits above the four principal ones. V. Kirxi, Hutton. Widely oval, spire depressed; last whorl ornamented with a small number of blunt tubercles; columella with four very profound plications, the upper part with a thin callous deposit. Color yellowish brown. Length 1°75, diam. 1°57 inches. New Zealand. Said to be a Cymbiola ; not figured. Possibly a young shell. 100 VOLUTILITHES, VOLUTOCONUS, CALLIPARA. Sect. 12. Volutilithes, Swains. Shell oval-fusiform, spire elevated, terminated by a pointed summit; whorls cancellated or longitudinally plicate; mouth oval-oblong ; columella with numerous rudimentary or obsolete plice ; lip thin. The group is represented by a single living species and numerous tertiary forms. VY. AByssicoLaA, Adams and Reeve. PI. 29, fig. 120. Fulvous ash-color, encircled by three or four narrow chestnut bands. Length, 1:5 inches. Cape of Good Hope, 132 fathoms. Only the type specimen known. Sect. 13. Volutoconus, Crosse. Oblong, subcylindrical, longitudinally and transversely striate ; spire short and obtuse, terminated by a rounded summit; columella with four slightly developed teeth; lip simple, slightly inflected in the middle; base with flexuous striz. VY. CONIFORMIS, Cox. PI. 30, fig. 129. Yellowish brown, with three broad chestnut bands, and super- posed upon the bands and interspaces irregular or triangular large and small white spots and blotches. Length, 70 mill. N. W. Australia. Has the system of coloration so frequently met with in a group of Conus. fect. 14. Callipara, Gray. Shell oblong, subcylindrical; spire short, nucleus small ; columella with two plications. VY. BULLATA, Swainson. PI. 29, fig. 116. Fulvous, with chestnut spots and angulated lines, and three darker bands of the same. Length, 2°5 inches. Algoa Bay, So. Africa. Resembles somewhat Conus bullatus. V. Brazieri, Cox. Pl. 29, fig. 117. Yellowish brown, with a wide irregular chestnut band, and chestnut markings. Length, 11 inches. New South Wales. The figure is enlarged. The spire is more sunken than that of V. bullata, but it may be only a color-variety of that species. AURINIA, MAMILLANA, LYRIA. 101 [Sect. 15. Aurinia, H. and A. Adams. Shell oval-fusiform; spire terminated by a large mamillary summit; columella with obsolete, scarcely apparent plications ; whorls of the spire finely transversely striated ; lip simple, thin. This group was proposed for V. dubia, Brod., known only to Messrs. Adams and Crosse from juvenile examples. The species is closely related to, if not identical with, V. Junonia, and follows that species in this monograph; Aurinia, consequently, will not stand. | Sect. 15. Mamillana, Crosse. Shell widely oval, ventricose, rather thin, intermediate between Voluta and Cymbium; nucleus papilliform, very strongly devel- oped, excentric and lateral; columella with a few oblique plice ; lip thin. V. MAMILLA, Gray. PI. 29, fig. 122. Yellowish, strigated with brown. Length, 6-8 inches. Tasmania; Australia. The first whorl of the spire is completely lateral in this species, as in V. rupestris. Undetermined Species. V. nana, Anton. Belongs to Vespertilio group. No locality given. V. LArGiniierTIANA, d’Orb. (Related to V. pallida, Gray.) Seas of India. V. PUMILIO, Brusina. Dalmatia. Not figured. Shell ovate, transversely closely striate; spire very short, apex obtuse; lip simple, acute; columella sub- uniplicate. I do not know where to place this species; it is certainly not a Voluta. Length, 7-16 mill. V. Morrgrana and V. SpeNGLERIANA, Martini, H. and A. Adams’ Genera, i, 161. 6enus LYRIA, Gray. Dr. Paul Fischer, who has studied the anatomy of Lyria deliciosa,* finds it to be essentially the same as that of Voluta, * Jour. de Conch., xv, 355, 1867. 102 LYRIA. except in the presence of an operculum and in the dentition (Pl. 2, fig. 7). The shell, however, presents certain modifica- tions from Voluta which, in connection with the operculum, suffice for the establishment of a legitimate artificial group, which may be characterized by the narrowness of its mouth, the predominance in size of the two columellar plications nearest the base, and the transverse rugosities covering the inner lip above the plications, their comparatively small size and mitriform aspect, and the externally thickened lip. The distribution is wide, including West Indies, West Coast of Central America, East Coast of Africa, Moluccas, Japan, Australia, ete. A few fossil species may be here referred; and notably V. harpula, Lam., of the Paris basin. The classification of the species is based on that proposed by Mr. H. Crosse.* * Shell smooth. L. peticrosa, Montr. Pl. 31, figs. 183-135. Pinkish gray, with distant revolving brown lines and inter- rupted bands; spire minutely longitudinally plicate; base of body-whorl with revolving incised lines. Length, 30 mill. New Caledonia. * * Shell obsoletely or faintly plicate. L. nucteus, Lam, PI. 31, fig. 136. Flesh-brown, here and there dotted and variegated with chestnut; lip and varices black-dotted. Length, 1—-1:25 inches. NV. HE. Australia. The spotted varices which occur occasionally upon this shell indicate the position of former rest-periods in its growth, being the thickened lip, which the animal in resuming growth has failed to absorb away. L. Beaut, Fischer and Bernardi. PI. 31, fig. 137. Yellowish flesh-color, with revolving chestnut lines, inter- rupted between the obsolete cost. Length, 70 mill. Marie-Galante, West Indies. A rare species. * Jour de Conch., 105, 1866. LYRIA, 103 L. CASsIDULA, Reeve. PI. 31, fig. 138. Cream or flesh-color, clouded with chestnut and white, with interrupted chestnut revolving lines. Length, 1—-1°25 inches. Japan. L. pusituA, Schrenck. PI. 31, fig. 139. Yellowish chestnut, with a band of red and white spots at the suture, surface maculated with rufous ; aperture yellowish chest- nut. Length, 9°5 mill. Japan. Described as obsoletely plicate, with two plaits near the base of the columella; neither of these features being very apparent on the enlarged figure of the species. Possibly a young ZL. cassidula? At any rate the specimen appears to be immature, for the description is “ labro simplici, recto.” ** * Longitudinal ribs strongly marked. L. DELESSERTIANA, Petit. Pl. 31, fig. 140. Flesh-color with orange-red maculations and bands and chest- nut revolving lines. Length, 2—2°25 inches. Madagascar. L. LYRZFORMIS, Swains. Pl. 31, fig. 141. Flesh-color, with revolving, interrupted chestnut lines, and blotches of the same arranged in three revolving bands. Length, 3°75 inches. Ki. Coast of Africa. The figure represents a very different looking shell from L. Delessertiana, but intermediate forms occur, and I am very doubtful of their distinctness. L. costaTa, Swainson. PI. 31, fig, 142. Whitish, with orange-red spots and interrupted revolving lines. Length, 2 inches. Moluccas ; Indian Ocean. L. Mirrz#rormis, Lam. PI, 31, fig. 143. Flesh-color or yellowish, with dark chestnut spots and revolv- ing lines, the latter sometimes broader so as to form interrupted bands. Length, 2 inches. Australia, Tasmania, Java, 8. Africa. LL. costata has a flattened shoulder, upon the angle of which the longitudinal ribs terminate in spines ; whilst L. Mitreformis 104 ENZTA. has a shelving shoulder merely obtusely angulated; yet I suspect that the two forms are mere varieties of one species. L. Arcueri, Angas. PI. 31, fig. 144. Yellowish, clouded and lined with chestnut; lip punctate with black, dentate within; columella with three strong basal plice, and numerous smaller ones above. Length, 1°33 inches. Montserrat, West Indies. The form and coloring are very like the preceding species, but the dentate lip is an extraordinary feature which may distinguish it from all others. The type is the only specimen known, and the locality is doubtful. Appears to connect Lyria proper with its subgenus Hneta. Subgenus Eneta, H. and A. Adams. Exterior lip thickened, inflected and bearing an obtuse tooth | upon its middle inner margin. L. HARPA, Barnes. PI. 31, fig. 145. Pale flesh-color or gray, with chestnut or chocolate angular spots and maculations, frequently forming faint interrupted bands. Length, 1—-1°5 inches. W. Coast of Central America. L. Cumrnet, Brod. PI. 31, figs. 146, 147. Pale flesh-color, clouded and lined with chestnut. Length, 1-1-5 inches. W. Coast of Central America, northward to San Blas. L. Cylleniformis, Sowb. (fig. 147), appears to be a small shell of this species. E. PepersENII, Verrill. Shell small, rather slender, elongated; the spire regularly conical, acute, about two-thirds the length of the body-whorl; each whorl much flattened below the suture and encircled by a row of rounded tubercles; the body-whorl with low, rounded, longitudinal costz below the tubercles. Whole surface finely longitudinally sulcated or striated,on the upper whorls also transversely striated. Color fulvous brown, specked with bluish white, with an inter- rupted band, or spots, of deep brown below the suture, a pale MICROVOLUTA. 105 band over the tubercles, and another, bordered with brown, below the middle of the body-whorl. Length, 1 inch. La Paz, oe California. Not figured ; said to be more slender, with the spire more acute, smaller tubercles and cost, a more prolonged and recurved siphon, and more contracted aperture than L. Cumingit. The surface is not smooth and the color is lighter. L. Guiupineit, Sowb. PI. 31, fig. 148. Fulvous, with white and darker lines; longitudinally ribbed, granose at the sutures. Length, ‘5 inch. I. St. Vincent, West Indies. I am not acquainted with the species. LL. euttata, Reeve. Pl. 31, fig. 149. White, maculated with brown; longitudinally plicate. Length, ‘5 inch. Honduras. Possibly identical with the last species; if so, it will become a synonym, Guildingit having priority of publication. L. CotumBELLA, Sowb. PI. 31, fig. 150. Small, oblong, smooth, pallid maculated with red; spire acuminate, aperture elongate; lip incurved in the middle; columella very obscurely plicate. Having the form of Colum- bella nitida, and showing rather faint plicz on the columella. The above is a copy of Sowerby’s description and figure. It is certainly not a Voluta, and appears more like a Marginella. Genus MICROVOLUTA, Angas. The deep siphonal notch, and the toothed projection of the base of the pillar;so characteristic of the Volutes, are absent in this curious little genus. M. Austrauis, Angas. PI. 31, figs. 151, 152.

The animal has a small, narrow head; tentacles close together at the base; eyes near the base or towards the outer middle of the tentacles; proboscis cylindrical, flexible, very extensible, mantle enclosed; siphon simple at the base; foot small, triangular, usually truncate in front. Some of the larger species have no operculum, but it is often present, though small and rudimentary, on the foot of the smaller species. Shell with acute apex, usually well developed spire and plicate columella ; for the most part destitute of epidermis, which is very thin, smooth and translucent when present. Mitra is related on the one hand with Voluta, on the other with Marginella ; it is distinguished from the former by its columellar plaits, of which the largest are posterior whilst in Voluta they are anterior, by its form, and the apex, which is never papillary; from Marginella it is distinguished by its much longer spire, less polished surface, generally large size and particularly by wanting the thick marginal varix of the lip. The dentition of the Mitride presents several distinct types ; so that Troschel and Gill have divided the family upon this character. The group Cylindra has the teeth of Marginella and is placed near that genus by these authors; the form of the shell also recalls Marginellide, and although the preponderance of characters accords with Mitra, it may be reasonably considered a connecting link with Marginella. Volutomitra has been placed in V olutidze on account'of the dentition of V. Granlandica, the only Arctic species of Mitra, but I have preferred to retain it and its congeners in Mitridz, because we know nothing of the dentition of the numerous tropical species. Turricula and Strigatella are allied by their dentition to the Olividee, and Imbricaria to the Turbinellide. Mitra has been divided by H. and A. Adams and others into a number of subgenera, whilst Sowerby separates the species into thirteen numbered but unnamed sections. The groups are certainly not entitled to subgeneric rank, yet I believe that the retention of Adams’ names for the sections is better than to MITRIDZ. 107 designate them merely by numbers. The grouping of the Species by these two authorities is in many respects widely different ; I have carefully compared them together, and with the shells, and shall attempt to improve upon both. The Mitras have been monographed by Kuster, Kiener, Reeve and Sowerby, the work of the latter being by far the most recent and complete, embracing nearly five hundred species. The “ Thesaurus ” was published in 1874, and since that date some additional species have been described ; there are also a number of species obscurely published or which, for some other cause, appear to have escaped Mr. Sowerby’s attention, so that in all the number of specific names which might nominally hold place in the present work would not be far from six hundred and fifty. The vast increase of our knowledge of Specific variation developed during the past few years has, however, induced a decidedly more conservative, and it is believed, more philosophic, view of species, than that prevalent only six years ago,so that I have been enabled to effect a vast reduction in the specific ranks—a reduction which will probably become still greater as additional material is given to the student for comparison. When irritated, some species of Mitra emit a purple fluid having a nauseous odor. The genus is at present tropical and subtropical in distribu- tion, but few small species being found in the colder latitudes. Bathymetrically they range from low-water to eighty fathoms, the smaller species being usually found along shore-lines. About a hundred fossil species have been described, commencing with the cretaceous period. M. Grenlandica, at present confined to Arctic waters, is found associated with M. cornea,a somewhat similar Mediterranean species in the latest British Tertiaries. The Mitridz inhabit various stations; many being strictly reef shells, where they lurk in holes and crevices under sea-weed, but are most generally concealed under stones and blocks of dead coral. Others burrow in sand or sandy mud at various depths; some delight in stony ground inside the reefs, where they remain concealed under clumps of coral during the day, and like the sand species are nocturnal in their habits. 108 MITRID A. Mr. Andrew Garrett* suggests that the Polynesian shells which have been described by H. and A. Adams under the name of Thala, as asubgenus of Mitra, are more nearly related to Pleurotomidz, the so-called folds of the columella not being true plaits, but simply more or less irregular transverse rugosities precisely of the same character as those upon certain species of Clathurella and Cithara of that family. Two species of true Mitre have, however, been referred to Thala, and I have preferred to retain the genus in the Mitridz for the present, upon duly weighing the value of its known character- istics. Mr. Pease’s genus Mitropsis is excluded, being a member of the family Columbellide, Finally, Mitromorpha, A. Ad., appears to be more nearly related to the Pleurotomide, several of its species having been described as Daphnelle. Synopsis of Genera. MITRA, Lamarck.

The animal of Mitra has in general a very short foot, straight and continuous from side to side in some species, but in others notched and produced, with a thickened anterior margin. It is commonly narrow and rounded, or acuminated posteriorly, and it often bears a very small semitransparent horny operculum, in 110 MITRA. some instances scarcely visible. The siphon is mostly directed forward, and the somewhat short, tapering tentacles have the eyes either situated about half-way or they are placed on the outer side of the base. The head is long and very flat, and the tentacles are very close together at their bases. The proboscis is rarely exserted when they are crawling and lively, but as they become languid after capture it becomes distended with water and protrudes considerably. The Philippine Islands would seem to harbor the greatest number of these elegant and beautiful shells, although a great many species were obtained by Mr. Cuming in tropical America. They appear to be chiefly confined to the equatorial regions, scarcely any being natives of cold climates. The transversely ribbed species are frequently found in very deep water, and many have been dredged in twenty and thirty fathoms at Sooloo and in the China Sea. Although M. Quoy has rightly termed the Mitra an “ animal apathique,” the small longitudinally ribbed species crawl about pretty briskly over the smooth sand among the low coral islands. The Mitra episcopalis, probably on account of the small size of its locomotive disk, and the ponderous nature of its long shell, is, however, a very sluggish mollusk. Some of the Auricula- shaped Mitres that live among the Philippines, in the shallow pools left by the receding tide, crawl about the stones out of the water, in company with Planaxis and Quoyia. The Mitres, like many of the large Volutes, prefer, however, to associate together, and may be seen in dozens crawling over the sandy mud-flats in shallow water, being most active just as the flood- tide makes. When the tide recedes, they bury themselves superficially in the yielding soil,and are with difficulty discovered. Some of the small-ribbed species cover themselves entirely with the sandy mud, and in that disguised condition travel about with comparative security.* Among the Bashu group, and more particularly on the island of Ibayat, the natives form very elegant and commodious pipes from different species of shells, the columella and septa of the convolutions being broken down, and a short ebony stem * Arthur Adams, Moll. Voy. Samarang, 26, 27. 5 MITRA. 11] inserted into a hole at the apex of the spire. A pipe of this manufacture, in my possession, is formed from the Mitra papalis, and I have seen others made out of Mitra episcopalis and of Cerithium and Terebra.* Typical Group. Mitriform, thick, spire elevated, apex sharp; mouth rather small and narrow, notched in front ; columella obliquely plicate ; lip rather thick, smooth within. * Hdge of lip crenated, whorls generally spirally grooved and punctured. M. Episcopatis, Linn. PI. 32, fig. 1. White, with somewhat quadrangular bright red spots, arranged in revolving series. Length, 2°5-6 inches. Ceylon, Philippines, Polynesia. M. papauis, Linn. PI. 32, fig. 2. White, spotted and blotched with deep scarlet in revolving series. Length, 3—4°5 inches. Kingsmill, Caroline and Paumotu Isles. Much more rare in Polynesia than WM. episcopalis, according to Mr. Andrew Garrett. M. pontiricatis, Lam. PI. 32, fig. 3. White, with oblong or square red spots in revolving series. Length, 2-3 inches. Polynesia, Animal creamy white, with opaque white dots. Sometimes the shell is encircled with impressed lines, which are deeply punctured at intervals. M. cARDINALIS, Gmelin. PI. 32, fig. 4. Whitish, encircled by rows of chestnut-bay spots. Length, 1°75—2°5 inches. Ceylon, Polynesia. Usually found in shallow water inside the reefs. Animal uniform creamy white. * Belcher, Narrative of Voy. of Samarang, ii, 448, 1848. 112 MITRA. M. Lamarck, Deshayes. PI. 32, fig. 5. A somewhat narrower shell than JZ cardinalis, with fewer and larger spots, which are longitudinally oblong. Length, 2—2-25 inches. Habitat unknown. It is possibly a variety of cardinalis in which approximate rows of spots have coalesced into larger ones. M. versicotor, Martyn. PI. 32, figs. 6-8. Yellowish or brownish white, variegated with chestnut-brown blotches and spots, and numerous small white spots edged with brown. Length, 2°25 inches. Red Sea, Zanzibar, Madagascar, Polynesia. The surface is usually ornamented with revolving incised lines bearing punctures. Several species have been manufactured out of slight variations of color and form; they can scarcely be designated as varieties. Among these are VW. nebulosa, Swains. teste Reeve (fig. 8); it is more clouded than the type, and with- out the white spots; JZ nubila, Gmel.,in which the spots become longitudinal, and narrowed into stripes; M. erronea, Dohrn, proposed for the shell figured by Kiener as MW. versicolor (fig. 7); and Reeve’s figure of M. nebulosa (fig. 8), the true nebulosa being, according to Dohrn, figured by Reeve as MM. infecta, drawn, he says, from the original type of nebulosa in the Cum- ingian Collection. To add to the confusion, Arthur Adams, at an earlier date, decided also that Reeve’s nebulosa was not that species, and accordingly renamed it I. propinqua. Finally, the shell which Sowerby figures as M. propinqua, A. Ad., is an entirely distinct species. M. PpROPINQUA, Sowerby. Pl. 33, fig. 11. White, with faded chocolate bands and longitudinal brown strigations. Length, 2°8 inches. Habitat unknown. Figured by Sowerby for M. propinqua, A. Adams, but no such species was ever described, Mr. Adams having given that name to Mr. Reeve’s M. nebulosa, which he considered different from Swainson’s. It seems to be a very distinct species. MITRA. 113 M. vARIEGATA, Reeve. Pl. 33, figs. 9, 10, 12, 13, 14. Whitish, clouded with pale chestnut. Length, 1°25-1°75 inches. Red Sea, Mauritius, Philippines. The type had an unusually depressed spire, for the species, accompanied by a slight angulation on the superior portion of the body-whorl. I have before me a specimen exhibiting similar divergence from the normal growth, but not quite so marked. In young, fresh specimens the spire is almost clathrate, the sutures especially being closely plicated ; when the shell becomes adult, and somewhat worn, this longitudinal sculpture mostly disappears. It is usually a heavier shell, but comes close enough to M. versicolor to give rise to doubts of its distinctness ; on the other hand it approaches certain species in which the edge of the lip is not erenulate, and as it is a certain fact that this character also is frequently obliterated with age, there is strong probability that eventually several other synonyms will be added, besides those which I herewith subjoin: these are M. nympha, Reeve (fig. 12), being the normal growth, M. Rossiz, Reeve (fig. 14), which is a full-grown and somewhat worn specimen, and probably IM. lacunosa, Reeve (fig. 13). If the latter is the same species, it will have priority over MW. variegata. M. SANGUINOLENTA, Lam. PI. 33, fig. 15. Shell encircled by punctate impressed strie. Yellowish red, strigate with chestnut and spotted with white. Length, 1:25 inches. Habitat unknown. This species is known to conchologists only through the type figured by Kiener ; Lamarck himself, according to his synonymy, appears to have confounded it with JZ versicolor. M. eximra, A. Adams. PI. 33, figs. 16, 17. White, clouded with chestnut. Length, 1 inch. Mauritius, Ceylon. Said to be somewhat clathrate by the growth-lines. Is very probably only astunted specimen of WZ. variegata. M. lacunosa, Sowb., not Reeve (fig. 17), is a more advanced stage of growth ; it is said to come from Ceylon. 15 114 MITRA. M. c#RuLFEA, Reeve. PI. 33, fig. 18. Whitish, clouded with bluish gray, with a few chestnut spots or strigations arranged in two revolving series, and below the suture besides ; orange-brown within the aperture. Length, 1°5 inches. Viti Islands. — Garrett. Highly colored as is this species, its form and sculpture are so like M. variegata, that I doubt its distinctness. M. Mavritrana, Sowb. Pl. 33, fig. 19. Cancellated by pitted grooves and longitudinal ridges ; white, with two broad bands of interrupted brown spots. Length, 1°5 inches. Mauritius. M. incisa, Ad. and Reeve. Pl. 33, figs. 20, 21. Whitish, variously clouded with purplish brown, sometimes forming two broad bands, variegated sometimes with small brown spots and whitish fine zigzag lines. Length, 22 mill. China, Andaman Islands. Sowerby considers M. Mariz, A. Ad. (fig. 21), a synonym, but Mr. E. A. Smith attempts to separate it on account of slight differences of form. I am satisfied that they are identical, and suspect that they are merely the young of a form of JM. variegata. M. sERPENTINA, Lam. PI. 33, fig. 22. White, indistinctly stained and zoned with orange, longitudi- nally painted with waved brown lines shadowed with white ; aperture yellowish. Length, 1°5—2°25 inches. Philippines, Polynesia. M. Deshayes remarks that IZ. variegata, Gmel., having priority of publication, should be used in place of serpentina; the latter has, however, become so well established that Reeve has used the former name for another recognized species, and under the circumstances it is better not to be too strenuous for the main- tenance of individual rights. M. Marquesana, A. Ad. Pl. 33, fig. 23. Color of M. serpentina, but finer sculpture, and much smaller size. Length, 23 mill. Marquesas Islands. Possibly not distinct from M. serpentina. MITRA. 115 M. Bovet, Kiener. Pl. 33, fig, 24. Turriculated, coronated with small tubercles, and encircled with close-set punctured strie. Ashy white, with two broad bands of ashy violet, flaked with numerous small, snow-white spots; brownish within. Length, 2—2°25 inches. Red Sea. In young specimens the tubercles are said to be scarcely apparent, and it may be doubted whether M. cerulea, Reeve, is not a non-coronate form of the same species, the painting being very similar. M. puncricunaTA, Lam. PI. 33, fig. 25. Whitish, tessellated with yellow, with two broad, irregular orange bands, upon which are longitudinal chocolate strigations ; aperture yellowish within. Whorls coronated, with closely punctured revolving incised lines, crossed by rugose lines of growth. Length, 1°5-1-75 inches. Philippines. M. Sopu1#, Crosse. Pl. 33, fig. 26. Yellowish brown, whorls tuberculated at the angle of the shoulder, with one or two rows of tubercles below it. Length, 43 mill. New Caledonia. The columella has six plications, whilst that of M. puncticulata has but four or five. : M. cratitia, A. Ad. Pl. 33, fig. 27. Pale yellowish white. Length, 1°6 inches. South Africa I am not acquainted with this species. * * Outer lip not crenulated on its edge, whorls seldom grooved or punctured. M. FioccaTa, Reeve. Pl. 34, fig. 29. Yellowish bay-color, longitudinally flaked with white, lip crenated near its base. Length, 2 inches. Habitat unknown. Described from a unique specimen in the late Cumingian cabinet. The lip is said to be crenulated near its base, and possibly finer examples may be crenulated throughout. It is a doubtful species, too close to WM. variegata, Reeve. 116 MITRA. M. cHALYBEIA, Reeve. PI. 34, fig. 30. Whorls smooth, grooved towards the base; rudely very finely crenulated next the sutures; longitudinally streaked with white and ashy blue, transversely indistinctly banded, encircled through- out with equidistant reddish brown lines; columella reddish orange, four-plaited. Length, 2 inches. Habitat unknown. Only one specimen known, in the Cumingian collection. Probably an individual variation from some well-known type, such as I. variegata. M. uimata, Reeve. Pl. 34, fig. 33. Shell rather thick, polished, transversely grooved throughout, grooves punctured; whitish, encircled by a pale white-flaked band. Length, 1 inch. Isl. of Bohol, Philippines. Probably a variety of I. variegata, Reeve. M. eurrata, Swainson. PI. 34, fig. 31. Yellowish brown, longitudinally mottled with white. Length, 2 inches. Ceylon. M. Fereusonr, Sowb. PI. 34, fig. 32. More volute-shaped than any other species ; it is smooth, solid, pale fawn, with fine articulated lines and a little cloud of chest- nut; spire rather short, obtuse; aperture large, with smooth outer lip. Length, 1°75 inches. Panama. I am not acquainted with this species. The authority for the locality is not given. M. ruoripA, Gould. PI. 34, fig. 35. Whitish, clouded with yellowish brown, with numerous revolving series of small brown spots; pinkish white within the aperture. Length, 1°75 inches. Dr. Gould’s type, received from Dr. Edmund Ravenel, of Charleston, 8.C., is said to have come from Florida; another specimen in the Jay Collection has the habitat Philippine Islands. Its characters are intermediate between Mitra and Voluta. My MITRA. Iba La figure is from Gould’s type, and I can add nothing to the above meagre information concerning this curious form. M. Deseranasit, Kiener. Pl. 34, fig. 34. More ventricose and thicker than M. variegata, less strongly cancellated on the upper portion of the two last whorls ; with three zones of spots upon the last whorl, one of them sutural, and the other two separated by a wide very light reddish-brown band. Length, 29 mill. Mauritius. Kiener’s description and my figure (copied) are from a dead and bleached specimen. Liénard gives the above particulars of coloration, and acknowledgesits close relationship to M. variegata —from which, nevertheless he distinguishes it. M. cANCELLATA, Kiener. PI. 34, fig. 36. Whitish, cancellated and pitted. Length, 1:3 inches. Habitat unknown. This shell has been overlooked by subsequent monographers ; I can make nothing out of it; it is evidently in bad condition, and only a single specimen is known, in the Massena Collection. There is a M. cancellata, Swainson, a very different species. M. HAmiLxet, Petit. Pl. 34, fig. 37. Brown, marbled and tinted with chestnut and olivaceous, finely cancellated by revolving incised lines and close growth- lines. Length, 1°5 inches. Cape Verd Islands.
