Habitat. — Flinders Passage, North Australia, in 7 fathoms; also Station 18(), off 

 Cape York, Torres Strait, in 8 fathoms. 



Only one or two small valves were collected. At this early stage of growth the 

 peculiar sculpture of this species is very fine indeed. Its occurrence in Torres Strait 

 and its distribution have been already recorded by the author iu the Report on tlie 

 "Alert" collections, p. 98.

Habitat. — Tenerife, Canary Islands, at a depth of 70 fathoms. 



This well-known form has previously been recorded from the Canary Islands, and may 

 eventually be found still farther south. It does not aj^pear to range farther north than 

 some parts of England and Ireland. It has received many names, and to give the com- 

 plete synonymy and list of references would be useless ; this being only advisable when 

 a monograph is attempted.
