December 26-27, 1873. Lat. 46° 43' S., long. 38° 4' 30" E. Between Marion Island 

 and Prince Edward Island. 50 to 140 fathoms. Volcanic sand.

I give this species on the authority of Dr Gwyn Jeffreys. I had remarked the shell's great 

 resemblance in form to Odostomia rissoides, but the distinct and strong spiral sculpture which 

 characterises it, coupled with the locality, prevented my referring it to that species.
