4. Exocetus exiliens, Biocn. 
- Bright silvery, with a blue or dusky tinge on the upper part ; fins dusky. Pectorals lan- 
ceolate, and scarcely extend to caudal ; anal and dorsal straight, low, and about equal ; cau- 
dal deeply forked, lower lobe nearly twice the length of the upper; ventrals large, situated 
a little beyond the middle of the abdomen. In young specimens, there are brown bands on 
the pectorals and ventrals.

Exocetus fasciatus, Lesurur, Journ. Acad. Nat. Sc., . p. 9; young (7). 
Cuvier, in his ‘‘ Régne Animal,” says, he thinks the Exocetus fasciatus of Lesueur is 
the young of Bloch’s E. exiliens. Dekay is of the same opinion; therefore I have thus 
arranged them. 
Exocetus mesogaster, Biocu. 
Silvery blue, with the ventral fins situated on the middle of the abdomen; they are mod- 
erately large, and rounded.

Although Cuvier observes, that ‘‘it is not easy to distinguish the exiliens and meso- 
gaster in the relations and the figures given by travellers,’’ and Richardson (Fauna Boreal. 
Americ., p. 131) observes that Dr. Mitchill’s notice of the H. mesogaster ‘‘ is too slight to 
prove that he has applied the name rightly,’’ I have introduced this species here, because it 
was noticed by Plumier in the Caribbean Sea, and by Mitchill’s using, in his description of this 
species, the very words of Shaw when describing this species (Gen. Zodl., v. p- 146), it is 
evident they answer perfectly to the description of his fish. Richardson is in error when he 
says, ‘‘ Dr. Mitchill mentions the mesogaster as an inhabitant of the sea of New York’’; 
for although this might be inferred from the fact of its being contained in his ‘‘ Memoir,”’ 
yet Mitchill says, ‘‘ The specimen I examined was brought from the ocean, somewhere to the 
south.”’
