Zealand.

 Off the Snares ; 60 fathoms ; rare and small. Twenty miles north of Auckland Is-

 the Mauritius, Kerguelen Island, and off Western Australia.

area ; and also from the " Challenger " dredgings. 



Present Occurrence. — Off the Snares ; 60 fathoms ; frequent. Ten miles north

 vol. ix, p. 434, pi. Iv. figs. 2-7. 



This is a rather variable species, and the only example found is by no means 

 typical. The aperture is situated on an inclined facet, and is distinctly pear-shaped,
