432 DE. GtiNTHEE ON THE FISHES OF CENTRAL AMEBICA. 



76. Caranx caninus. 

 D-S]! A.2|l. L.lat.24. 



The teeth in the upper jaw form a villiform band, those of the outer series being 

 much the stronger, and widely set. Lower jaw with a single series of rather strong, 

 closely set teeth, and with the two anterior ones somewhat enlarged, canine-like ; teeth 

 on the vomer, the palatines, and the tongue. The height of the body is a little more 

 than the length of the head, and one-third of the total (without caudal). Snout 

 obtuse, as long as the diameter of the eye ; eye with an adipose eyelid in front and 

 behind. Praeorbital much narrower than the orbit. The maxillary extends beyond 

 the vertical from the centre of the eye. Breast naked ; lateral line slightly bent, the 

 width of the arch being contained once and one-third in the length of the straight 

 portion ; the latter commences in the vertical from the fifth dorsal ray ; the plates do 

 not reach forward to the end of the arched portion, and are well developed. Lower 

 jaw scarcely projecting beyond the upper. Dorsal spines rather stout and short; the 

 fourth is the longest, and one-third of the length of the head. The pectoral extends to 

 the fifth anal ray. A black opercular spot. Membrane of the soft dorsal and anal 

 blackish. 



One specimen, 7^ inches long, was discovered by Capt. Dow at Panama. 



77. Cakanx dorsalis. 



Carangoides dorsalis, Gill, Proc. Acad. Nat. Sc. Philad. 1863, p. 166. 



D. 4-5 1 4 A. 2|i. L. lat. 25*. 



The teeth in both jaws form villiform bands ; teeth on the vomer, the palatine bones, 

 and on the tongue. The height of the body is contained once and four-fifths in the 

 total length (without caudal), the length of the hand thrice and one-fourth. The first 

 dorsal fin is but little developed, the spines being short, feeble, and flexible. Anterior 

 rays of the dorsal and anal fins prolonged into a very long filament, sometimes longer 

 than the whole body. Jaws equal in length, the maxillary extends to the vertical from 

 the front margin of the orbit. Lateral line bent, the width of its arch being as long as 

 the straight portion ; the latter commences below the middle of the second dorsal fin. 

 The plates are moderately developed, and commence at some distance from the bend of 

 the lateral line. Gill-membrane above the pectoral blackish ; posterior half of the 

 ventrals black. 



Panama. We have received two examples from Capt. Dow, one 19 inches long. 



* Mr. GiO counted 44 ; this is either a mistake, or he has counted small scales not deserving the name of 

 platea.
