Iviener's X. dcrtntisata (fig. 227) is synonymous, and his locality 

 ' W. Coast of Africa," as Avell as that given by Reeve for 

 decuxxata >k Brisbane Water, E. Australia," are both erroneous. 

 N. an<julifer<i, A. Ad. (fig. 228 >, is a juvenile shell; it comes 

 from Galapagos (at ten fathoms), on the authority of Cuming. 

 A'. runeiH'cnx, C. B. Ad., and N. acuta. Carpenter (not Say), both 

 untigured. are evidently the same species.

 white. Length. 1 inch.

Notwithstanding the greater prominence of the revolving-

 formiti.
