A rather common species of which very fine specimens have been secured. 



The radula of a male specimen from Stat. 153 has about the same structure as in the 

 preceding species. The angles of the anterior margin of median tooth (M) are not very prominent, 

 the three principal denticles of the posterior margin are moderately long and rather broad, 

 with intermediate smaller denticles. The laterals (i) have a moderately broad base and a curved 

 point. Number of rows about 190. The penis of this specimen is compressed, at its base about 

 2 Mill., it is soon turned up at about \^\„ Mill, from that base, then it becomes broader, its 

 greatest breadth being 2^2 Mill., the upturned part is about 9 Mill, in length, plicate, with 

 crenulated margins, at its top it is sudden narrower and ends in a narrow, hooklike part, long 

 about 3^2, thick about Y2 ^^i^^-
