TEREBR A. 



Plate XIV. 



Species 58. (Fig. a, b, Mus. Cuming.) 



Terebra cancellata. Ter. testa acute tereti, fulvd vel 

 livido-grised, vel cinered, anfractibus plano-convexis, 

 superne snlco divisis, costis oblique concentricis, ad 

 marginem crenatis, confertim regulariter exsculptis, 

 interstitiis lineis tenuibus elevatis cancellatis ; aper- 

 turd pared, columella subrectd. 



The cancellated Terebra. Shell sharply terete, ful- 

 vous or livid-grey or ash, whorls flatly convex, di- 

 vided by a groove at the upper part, closely regularly 

 sculptured with obliquely crenated ribs, creuated at 

 the margin, interstices cancellated with tine raised 

 lines; aperture small, columella nearly straight. 



Q,uoy and Gaimard, Voy. de 1' Astrolabe, Moll. vol. ii. 

 p. 171. pi. 36. f. 27, 28. 



Hab. Philippine Islands (in sandy mud, at depths of from 

 six to twenty-five fathoms) ; Cuming. 



In the livid-grey variety of this species the columella 

 and aperture are of a bright shining chestnut-colour. 



59. (Mus. Cuming.) 



Terebra flavescens. Ter. teal/I acute tereti, flavescente, 

 anfractibus plano-convexis superne sulco divisis, con- 

 centrice dense costatd, costis ad marginem crenatis, in- 

 terstitiis sulcis tenuibus linearibus cancellatis; aper- 

 turd pared, columella contorto-recurvd. 



The yellowish Terebra. Shell sharply terete, yellow- 

 ish, whorls flatly convex, divided by a groove at the 

 upper part, concentrically closely ribbed, ribs cre- 

 nated at the margin, interstices cancellated with fine 

 linear grooves ; aperture small, columella twistedly 

 recurved. 



Deshayes, Pro. Zool. Soc. 1859, p. 299. 



Hab. Sandwich Islands ; Pease. 



This species is remarkably like the preceding, but it 

 will be observed on comparing them that in T. cancellata 

 the columella is straight, while in T. flavescens it is con- 

 tracted and twistedly recurved. 



Species 60. (Mus. Cuming.) 



Terebra cingula. Ter. testa obeso-siibidald, crassd, 

 spadiced, fuloo-casianeo maculatd, interrupt) fasciatd, 

 anfractibus couvexo-planis, primis sulco divisis et con- 



fertim plicato-liralis, ceteris lavibus ; aperturd sub- 

 oblongd, columella crassd, recta. 



The girth Terebra. Shell stoutly subulate, thick, 

 fawn-colour, encircled with blotches and interrupted 

 bands of fulvous-chestnut, whorls convexly flattened, 

 the first divided by a groove, and closely plicately 

 ridged, the rest smooth ; aperture somewhat oblong, 

 columella thick, straight. 



Kiener, Icon. spes. viv. p. 28. pi. 8. f. 16. 

 Terebra fatua, Hinds. 



Hab. Island of St. Christopher, West Indies (on the 

 sand) ; Miller. 



The shell here figured is the type of Mr. Hinds' T. jut mi. 

 On further examination and comparison, 1 find it to be a 

 large discoloured specimen of M. Kiener's T. cingula, 

 which has been quoted in Plate V. as a smooth variety 

 of T. Senegalensis. The question arises, — Is T. cingula, 

 now that we know its habitat to be the West Indies, a 

 species really distinct from T. Senegalensis ? The habitat 

 furnishes no evidence of its distinctness, because, as we 

 have remarked in Plate IV., under T. variegata, " it is 

 well known to those who have studied the geographical 

 distribution of animal life, that the Fauna of the West 

 African seas north of Sierra Leone, is in part identical 

 with the Fauna of the seas of California and the West 

 Indies." In the absence of further observation, however. 

 we venture to describe T. cingula under the present head, 

 as a species, and withdraw it from the list of synonyms of 

 T. Senegalensis, which is of a somewhat lighter structure 

 and more ventricose ; but the question remains open to 

 doubt. 



Species 61. (Mus. Cuming.) 



Terebra tuberculosa. Ter. testa pyramidali-subulatd, 

 lenuiculd, peUucido-cinered, versus apicem livido-pur- 

 purasceute, juxta suturam obscure rufo-puuetatd, an- 

 fractibus declivo-ptanalis, superne sulco dicisis, ad 

 marginem couspicue fuuieulafis el tuberculato-granatis, 

 infra sulcum laevigata, nitente. deinde longitudin 

 seriatim granatin ; aperturd arcuatim oblongd, colu- 

 mella contorto-recurvd el liratd. 



The tubercled Tekebra. Shell pyramidally subulate, 

 rather thin, transparent-ash, livid-purple towards the 

 apex, obscurely red-spotted next the suture, whorls 

 slopingly flattened, divided at the upper part bj a 



May, I860.
