REPORT ON THE GASTEROPODA. 217 



Habitat. — Betsy Cove, Kergueleu Island (v. Martens), Betsy Cove, Kerguelen Island, 

 5 to 7 fathoms (Studer). 



In form both of shell and of operculum this species perfectly agrees with the characters of E. 

 Smith's genus Neobuccinum. The epidermis is indeed different, being in Neobuccinum eatoni, Sm. 

 (which is the type of the genus), smooth and shining, while in this species it is distinctly and irregularly 

 puckered spirally (as is feebly the surface of the shell beneath), and these spiral puckerings are set 

 with short harsh seta?, which are very easily broken off. Such a difference, however, is of no great 

 consequence, nor does the character of the epidermis form a feature of Mr Smith's generic 

 description. In both species the epidermis is curiously caducous ; especially is this the case in 

 Neobuccinum eatoni. The dentition is practically identical. V. Martens proposed Chlanidota as a 

 subgenus for this species, but accompanied it with no definition, so that Smith's genus, which 

 was published in the Royal Society's Philosophical Transactions in 1877, has priority.
