TEBEBRA.— Plate IX. 



Terebra castanea, Kiener (not of Hinds). 

 Terebra laurina, Hinds. 

 Terebra luctuosa, Hinds. 

 Terebra sli/lata, Hinds. 

 Terebra Jamaioensis, C. B. Adams. 

 Hob. West Africa (in sandy mud, in shallow water) ; Hen- 

 nan. Japan; Hinds. Cagayan, Island of Mindanao, 

 Philippines (in sandy mud, at the depth of twenty- 

 five fathoms) ; Cuming. West Indies ; C. B. Adams, 

 Beau, Dr. Hornbeck. Mazatlan ; Carpenter. 



Characterized by a uniform cinereous colour and shining- 

 chestnut columella, and by the delicate concentric plica- 

 tions of the upper part of the whorls, round which there 

 is only a scarcely perceptible depression in the place of the 

 customary groove. The geographical distribution of the 

 species is curious. The variety figured is Mr. Hinds's 

 T. laurina, from West Africa ; the variety nearest allied to 

 it, of which I have numerous specimens under examina- 

 tion, both from Mr. Cuming's and M. Deshayes' collec- 

 tions, is from the West Indies. The Japan and Philippine 

 variety is smaller, with the plications rather more strongly 

 developed, with sometimes a row of purple spots running 

 through them ; and the Mazatlan variety is of a leaden-blue. 



In 1857, Journ. de Conch, vol. vi. p. 80, M. Deshayes 

 considered Mr. Hinds's T. luctuosa and styloid distinct 

 species, separate from Mr. C. B. Adams's T. Jamaioensis. 

 In 1859, Pro. Zool. Soc. p. 290, M. Deshayes inclined to 

 think that T. luctuosa, sli/lata, and laurina, though still 

 quoting them as distinct species, should be united to T. 

 Jamaioensis. 1 unhesitatingly assign the whole, including 

 the red-discoloured specimen named T. castanea by M. 

 Kiener, which is not T. castanea, Hinds, to the Buccinum 

 cinereum, accurately described and figured by the Baron 

 de Born, in 1780, in his Test. Mus. Cebs. Vindobonensis. 



The shell incorrectly assigned to Bora's B. cinereum by 

 Hinds, is a variety of his T. inconstans. 



Species 36. (Mus. Cuming.) 

 Terebra lanceata. Ter. testa acuminato-subulatd, gla- 

 berrimd, nitente-albd, jiammulis luteis obliquis subdis- 

 tantibus longitudiualiter pictd, anfractibus declivi-pla- 

 natis, primis crenulato-plicatis ; aperturd parvd, colu- 

 mella recta, subtruncatd. 

 The lanced Terebra. Shell acuminately subulate, 

 very smooth, shining-white, longitudinally painted 

 with oblique, rather distant yellow flames, whorls 

 slopingly flattened, the first crenulately plicated ; 

 aperture small, columella straight, slightly truncated. 

 Buccinum lanceatum, Linnaeus, Syst. Nat. p. 1206. 

 Hab. Tahiti (in sandy mud, on the reefs) ; Cuming. 



A polished, porcelain-white shell, obliquely longitudi- 

 nally painted with distant hair flames of reddish-yellow. 



Species 37. (Mus. Cuming.) 

 Terebra nimbosa. Ter. testa subulatd, ad basin trun- 

 cato-ventricosd, griseo-albd, cinereo-fusco longitudina- 

 liter nebuloso-undatd, anfractibus declivi-planalis, la- 

 vibus ; aperturd parvd, columella recta, truncatd. 

 The rainy Terebra. Shell subulate, truncately ventri- 

 cose at the base, greyish-white, longitudinally nebu- 

 lously waved with ash-brown, whorls slopingly flat- 

 tened, smooth ; aperture small, columella straight, 

 truncated. 

 Hinds, Pro. Zool. Soc. 1843, p. 151. 

 Hab. Red Sea ; M. Botta. 



A grey-clouded species, of very simple character, en- 

 circled with a faint depression in the place so frequently 

 occupied by a groove.
