According to Streets, the East Indian representative of the type of 
Trachurops (Caranx mauritianus Quoy & Gaim.), is a different species 
from the American form. It is, perhaps, doubtful to which species the 
name crumenophthalmus was originally applied, as we find no definite 
‘record of the occurrence of our species on the coast of Guinea, the 
locality assigned by Bloch. This species is common inthe West Indies, 
and ranges occasionally northward to Cape Cod. Numerous specimens 
have been taken at Cape San Lucas and at Panama. We do not see 
that these differ from the Atlantic type.

Caranx heteropygus Poey, Memorias Cuba, ii, 344, 1860 (Cuba). 
Carangops heteropygus Poey, Enum. Pise. Cubens., 77. : 
Habitat.—Cape Hatteras to Brazil. Common in the West Indies. 
There is nothing in the description of C. secundus to show that it dif- 
fers from C. amblyrhynchus. As Poey considered them different, we 
place it in the synonymy of the latter with doubt. 
10. Caranx atrimanus Jordan & Gilbert. 
Caranx atrimanus Jordan & Gilbert, Bull. U. S. Fish Com., 1882, 309 (Panama). 
Habitat.—Pacifie coast of tropical America; Panama. 
This rare species is as yet known only from Panama. 
11. Caranx vinctus Jordan & Gilbert.—Cocinera. 
Caranx vinctus Jordan & Gilbert, Proc. U. S. Nat. Mus., 1882, 349 (Mazatlan). 
Caranzx sp. Lay & Bennett, Beechey’s Voyage, 1849, 55 (San Blas, Mazatlan). 
Habitat.—Pacitic coast of Mexico, Mazatlan, San Blas, Punta Arenas. 
This well-marked species is abundant about the entrance to the Gulf 
of California, its range extending thence to the coast of Central America, 
specimens having been taken by Professor Gilbert at Punta Arenas. 
12. Caranx leucurus Giinther. 
Caranx leucurus Giinther, Proc. Zool. Soc. Lond., 1864, 24, and Fish. Centr. 
Amer., 1869, 430 (Panama). 
Caranx fiirthi Steindachner, Ichth. Beitr., iv, 12, 1875 (Panama). 
Habitat.—Pacifie coast of tropical America; Panama. 
This species we have not examined. The five known specimens are 
from Panama, andall areimmature. There can, we think, be no doubt of 
the identity of fiirthi with leucurus.
