MARINE MOLLUSCA OF THE SCOTTISH NATIONAL ANTARCTIC EXPEDITION. 139 



Hab. — Station 325, Scotia Bay, South Orkneys, 9-10 fathoms, off weed and 

 stones, April-August 1903. 



A very compact little species, of which a few examples, all precisely similar in size 

 and sculpture, occurred. It is likely they are nearly, if not quite, adult, and are con- 

 spicuous for the strong, acute spiral lirse or riblets encircling the three lower whorls in 

 a uniform fashion, there being seven on the body-whorl.

Hab. — Trawl, Scotia Bay, South Orkneys, 9-10 fathoms, December 17, 1903, and 

 February 20, 1904. 



Several examples, mostly in live condition. The shell is of such thin texture, and 

 the animal, perhaps, so large and swollen proportionately, that most examples were found 

 to have their penultimate whorls broken, and the flesh protruding, when dredged up.
