Our arrangement of the Carangoid genera agrees with that given by 
Liitken (Spolia Atlantica, 1880, 124), with the following exceptions: 
We do net regard Gallichthys (Blepharis) as a genus distinct from 
Caranx, as neither of the two-characters assigned by Liitken to the 
former genus (partial or total absence of scales and disappearance of 
the spinous dorsal) is diagnostic. Neither can be used to draw a line 
between Caranz otrynter and Caranz crinitus. We refer the subgenus 
Vomer to Caranzx rather than to Selene, as it really possesses the lateral 
shields of the former. 
ANALYSIS OF AMERICAN SPECIES OF CARANX.* 
a. Shoulder-girdle with a deep cross-furrow at its junction with the isthmus, above 
whichis a fleshy projection ; body elongate, the 
depth about 3} in length (Zrachurops Gill). 
b. Teeth, feeble, inanarrow band above, the outer slightly enlarged; eye very large, 
with large adipose eyelid, its diameter about 
3 in head; interopercle and branchiostegals 
truncate behind; breast scaly; lateral line 
scarcely arched, its plates small, about 40 in 
number; soft dorsal and anal slightly falcate, 
with conspicuous basal sheath; pectoral shorter 
than head; 2d D.1, 25; A. 1, 21. 
CRUMENOPHTHALMUS, 8. 
aa. Shoulder-girdle normal, its surface even. 
c. Teeth of jaws in few series, unequal or at least not forming villiform bands, 
the outer series above usually enlarged, the 
lower teeth usually uniserial. 
* We are unable to place the following species in the key, on account of imperfec- 
tions in the description: 
Caranx peruanus Tschudi. 
Caranz peruanus Tschndi, Fauna Peruana, Ichthyologie, 1845, 19 (Peru). 
This species remains thus far unidentified. The following is an outline of the descrip- 
tion, which seems to be erroneous in some respects: 
D. IX, 1, 28. Depth 64 in length (with caudal); head 4 (without caudal). Mouth 
not extending toeye. Teeth all fine and villiform. Teeth on tongue, vomer, and 
palatines. Eye large. Lateral line sharply bent. Second dorsal highest in front. 
Pectoral extending to first ray of softdorsal. Color, dark bluish above; belly not very 
pale.
