Warted file-fish. 



Balistes Verrucosus. B. pinna dorsali anterior e triradiata, cduda 



ordine triplici Derrucarum. Lin. Syst, Nat. 

 File-Fish with the first dorsal fin three-rayed^ and a triple ifow 



of warts on each side the tail. 



So closely allied to the B. aculeatus as to appear 

 rather a variety of that species than truly distinct; 

 the chief difference consisting in the extremities of 

 the body being furnished on each side with three 

 rows of warts rather than spines.

Balistes Biaculeatus. B. griseus, dorso fuscOf spinis ventralihus 

 elongatis acutis.

 ventral spines.
