Hab. ? 



There is some resemblance in the general aspect of this 

 species to young specimens of the common Buccinum 

 iindatum.

 Nassa reticulata, Deshayes. 



Ilnb. Seas of Europe. 



The principal variation in this species consists in the 

 plaits being small and close-set, or larger and more distant.

The fine-ribbed Nassa. Shell ovately conical, acumi- 

 nated, whitish, blotched and interruptedly banded with 

 blackish-chestnut, gi-anulately decussated throughout 

 with fine longitudinal and transverse ridges, encircled 

 with a smooth canal beneath the sutures ; aperture 

 rather small, columella wrinkled, short-laminated, in- 

 terior ridged.

Hab. Curimao, Philippines ; Cuming. 



A fine characteristic species of solid growth, granulated 

 throughout by the crossing of numerous longitudinal and 

 transverse ridges.
