NASSA TRIFASCIATA, A. Adams, Proc. Zool. Soc. 1851, 

 p. 113. (? = N. labiosa, J. Sowerby). Several specimens 

 in good condition from Port Elizabeth. The original type 

 came from Vigo Bay. It is doubtful whether Marrat's N. 

 vincta from West Africa is really distinct.

Hab. Port Elizabeth. 



A lovely little shell, of which I have only seen a single 

 specimen, found by Mr. Crawford. It may well be dis- 

 tinguished from its congeners by the delicate plication 

 of the whorls, and the exquisite arrangement of brown lines 

 with which it is ornamented.
