68 Mr. E. A. Smith on some new 



ternaily with StrutMolaria ; and although the shell has more 

 the general aspect of Buccinnm, there can be no doubt of its 

 true location. The species which compose this genus are 

 strong thick shells ; this, on the contrary, is particularly fragile, 

 and clothed with a very thin deciduous epidermis. 



2. Buccinopsis Eatoni, sp. nov. 



Testa elongato-ovata, turrita, tenuis, Levis, pallide livido-fuscesccns, 

 haud nitens ; anfractus 6 ? (apiee fracto), reliqui 4 perconvexi, 

 lente accrescentes, lseves, incrementi lineis ilexuosis insculpti, 

 sutura profunda fere canaliculata sejuncti ; apertura ovata, longi- 

 tudinis totius circiter A aequans ; columella lsevis, polita, medio 

 leviter arcuata, versus basim obliqua ; canalis latissimus, per- 

 brevis, vix recurvus ; labrum simplex, tenue. 



Operculum ovatum, concentrice plicato-striatum, nucleo laterali, vix 

 terminali. 



Long. 56 mill., diam. 27 ; apertura long. 27 mill., diam. 14. 



Hab. Royal Sound and Swain's Bay, Kerguelen's Island. 



This is a very remarkable species, and chiefly characterized 

 by the smooth convex whorls, which are destitute of all sculp- 

 ture and ornamentation with the exception of the lines of 

 growth. The suture is particularly deep, and almost amounts 

 to a canaliculation. Around the short cauda of the body- 

 whorl, from a little below the middle of the columella, runs a 

 carination (which frequently occurs in species of Bullia), and 

 joins the basal channel near the lip. 



The operculum is peculiar in that the nucleus is not terminal 

 as in Buccinopsis Dalei 7 but situated on the inner side about 

 one tenth of the entire length from the extremity, and just 

 at this point the outline is interrupted by a slight sinus. It 

 consists of one whorl, which gradually increases by concentric 

 layers well defined by the lines of growth ; the inferior surface 

 is somewhat thickened along the outer edge — that is, that oppo- 

 site the nucleus. Such slight differences are scarcely sufficient 

 to warrant a generic separation. 



3. Trophon albolabratus, sp. nov.
