Gnathanodon speciosus Bleeker, Verh. Bat. Gen., xxiv, Makreele, 72, 1852. 
Caranx panamensis Gill, Proc. Ac. Nat. Sci. Phila., 1863, 166 (Panama). 
Habitat.—Tropical parts of the Pacific Ocean, East Indies, Mazatlan, 
Panama. 
This species is generally common on the Pacific coast of tropical 
America. Our specimens agree fully with the descriptions of the 
East Indian form. 
23. Caranx orthogrammus Jordan & Gilbert. 
2? Scomber ferdau Forkal, Deser. Anim., 1775, 55 (Red Sea). 
? Caranxz ferdau Giinther, Fische der Siidsee, 1876, 134 (Red Sea; Polynesia). 
Caranz orthogrammus Jordan & Gilbert, Proc. U. 8. Nat. Mus., 1881, 226 (Clarion 
Island, Revillagigedos). 
Habitat.—Islands off the Pacific coast of tropical America. ?Poly- 
nesia. . 
It is possible that this species may prove to be identical with Caranz 
Jerdau, or some related species. The single large specimen known, how- 
ever, differs materially from all the published descriptions of species of 
this type. 
24. Caranx otrynter* nom. sp. nov. 
Carangoides dorsalis Gill, Proc. Ac. Nat. Sci. Phila., 1863, 166 (Panama; not 
Vomer dorsalis Gill). 
Caranz dorsalis Giinther, Fish. Centr. Amer., 1869, 432 (Panama); Jordan & 
Gilbert, Proc. U. 8. Nat. Mus., 1882, 375 (Panama). 
Habitat.—Pacifie coast of tropical America; Mazatlan; Panama. 
This species marks the transition from “ Caranx” to “ Blepharis.” 
The adult would be referred to the latter genus, while the young might 
find place in Carangoides if these petty subdivisions should be retained. 
The relations of C. otrynter with C. armatus (Forskal) are rather close, 
but ‘the two seem to be satisfactorily separated. 
Compared with typical species of Caranx (as C. hippos), C. otrynter 
differs strikingly in many respects, among others the following: The 
greater compression and elevation of the body, the greater length and 
sharpness of the breast, the much greater depth of the preorbital region, 
the greater prominence and sharpness of the frontal and occipital keel, 
the more oblique position of the bones of the head, the feebleness and 
uniformity of the teeth, the approximation below of the mandibular 
rami, the reduction in size of the scales and scutes, and the increase 
of the naked areas, the reduction or loss (in the adult) of the dorsal and 
anal spines, the increase in length of the lobes of the dorsal, anal, and 
caudal, and, finally, the increase in the difference between the old and the 
*Orpvurtnp, a driver, in allusion to the whip-like ray of the second dorsal.
