Habitat. — Cape Adare, 24-26 fathoms. 



Previously known only from Kergueleu Island. The specimens 

 from Cape Adare are almost identical with those from Kerguelen. 

 Some of them, however, are less contracted at the base of the body- 

 wdiorl, and others are of a reddish-brown colour, which is most 

 observable within the aperture. They do not offer much variation 

 in form, but some specimens are a little stumpier than others. Very 

 remarkable is the small size of the operculum, which occupies less 

 than one-fourth the length of the aperture.

Hahitat. — Auckland Islands, 10 fathoms. 



It is possible tliat the above may not be the dimensions of a 

 full-grown specimen of this species, for there is a look of immaturity 

 about all the four examples obtained. Still I have not liesitated to 

 describe this form as a new species, as it is so clearly characterized 

 by the peculiar oblique lira around the anterior narrowed extremity 

 of the last whorl. In addition to the longitudinal ribs and the 

 transverse ridges, the surface exhibits very fine lines of growth and 

 some traces of fine spiral striae.
