 singular appendage to the lower jaw of this species by which it may be easily 

 recognized.

% This fish I have been unable to identify with Buchanan's description, I may 

 therefore have described it under another name ; he says the head is blunt, oval, small, 

 and smooth, which scarcely applies to either of the foregoing, in which the head is re- 

 markably lengthened ; that of B. hexayonolepis would come nearest to it, though some 

 of the others seem to correspond more in other respects with the account given. Pise. 

 Gang. 303. 



§ From Mega large, and lepis a scale.
