 short and blunt, the dorsal commencing before the 

 middle, the anal rather behind it, and both uniting

 Risso, which occurs in the Mediterranean, is identi- 

 cal with the fish ju^.t noticed.

 figure of it, unaccompanied with description, con- 

 siderable doubts exist as to the identity of his fish 

 with the one above named. Colonel Montagu 

 afterwards procured an example of what he con- 

 sidered to be 0. imherhe, and described it under that
