Japan, Australia, Central Polynesia. 



Differs from the Xassa 1 preceding it in this group by its pupi- 

 form shape and comparatively small body-whorl and mouth. 

 The spire is sometimes much exserted, causing very deep 

 sutures. The variable painting, etc., has caused a very large 

 synonymy, namely .V. jt1<>hccnt(i, Gould (unfigured), N. micros- 

 l.omn. Pease (fig. 247), A T . uniftnteiafa and N. turricula, Pease 

 MS., N. bfilfMift. Pease (h'_>. 248). .V. ili'i-mettina, Gould (un- 

 figiD-ed). X. frtifi't'ciilun. Dunker (Jig. 249), is a stouter form, 

 which may possibly be identical with the next species. N. 

 .SY/wo^x/.s. Dunker MS., and .V. lnie>ola, E. A. Smith (tig. 250), 

 from Japan, described from a single dead specimen, are very 

 probably synonyms.
