204 Panama Shells. NERITID^E. 



Station. In wet sand. 



Habitat. Callao ; Petit in sched. 



Taboga ; C. B. A. ! 

 We found only 2 specimens. 



303. Natica - . Sp. indet. c. 



Station. Unknown . 



Habitat. Panama ; C. B. A. ! 



We obtained only 1 imperfect specimen. It may possibly be 

 a variety of N. Elence, Eecl. It scarcely differs from N. Haneli 

 Keel, except in the absence of spiral striae (which a better speci- 

 men might exhibit), and in the continuity of the transverse 

 impressed lines across the last whorl. 



IVERIT A. In this genus we found an incredible profusion 

 of individual?, all of which belong to only two species.
