Rab. — New Caledonia. 



Tliough of simple character this little shell does not seem to 

 approach very closely to any hitherto known species. It is oval 

 in form, rather solid, with a rather elevated spire ; its surface is 

 smooth, with the exception of a few inconspicuous oblique plicae near 

 the suture. The umbilicus is entirely covered by a thick white 

 callus. The colouring of the shell consists chiefly of a broad brownish- 

 grey belt, covering more than half of the body-whorl.

Hah. — Kii, Japan (Hirase). 



The colour spots adorning this shell resemble those of N. pellis- 

 tigrina (Chem.), but it differs considerably from that species in form 

 and substance. It is quite thin and transparent, regularly globose 

 in form, and has a thick rounded callus entering the umbilicus, while 

 the columella is rather thin. Tlie suture is very narrowly channelled. 



Nassa kuglypta, n.sp.
