417. TRACHUROPS, Gill. 



Trachurops, GILL, Proc. Ac. Nat. Sci. Phila., 431, 1862, (crumenopJiUtalmws). 



This genus is close to Caranx, differing in the more elongate form and 

 especially in the structure of the shoulder girdle which has a deep cross- 

 furrow at its junction with the isthmus, with a fleshy projection above 

 the furrow. Species few, found in all warm seas. (Trachurus; tty, 

 appearance.) 



1304. TRACHUROPS CRUMBNOPHTHALMUS (Bloch). 

 (GooGLER ; BIG-EYED SCAD ; GOOGLE-EYE JACK. ; CHICUARBO.) 



Head 3* ; depth 3* ; eye 3. D. VIII-I, 26 ; A. II-I, 22 ; scutes 35. Body 

 oblong elongate, little compressed, the back not elevated. Head elongate, 

 rather pointed, the lower jaw projecting ; maxillary reaching past the 

 front of the eye, which is very large, longer than snout, much deeper 

 than the cheeks, and greater than the interorbital width. A single series 

 of small teeth in each jaw ; very weak teeth on vomer and palatines; a 

 patch of teeth on tongue. Shoulder girdle near isthmus with a fleshy 

 projection, in front of which is a deep cross furrow ; adipose eyelid largely 

 developed. Scales comparatively large. Cheeks and breast scaly. Gill 

 rakers long, numerous. Lateral line scarcely arched, its scutes weak, but 

 little carinated. Dorsal spines slender ; free anal spines strong ; pectorals 

 falcate, shortish, about 1| in head. An angle at lower posterior part of 

 opercular region as in Clupea. Bluish olive above, silvery below, a faint 

 opercular spot. Length about 2 feet. Both coasts of tropical America, 

 occasionally north to Cape Cod ; common in the West Indies and on the 

 west coast of Mexico ; specimens examined by us from Cape San Lucas, 

 Mazatlan, Acapulco, and Panama. We are unable to see any difference 

 between the Pacific Coast form Trachurus brachychirus, Gill, and the ordi- 

 nary cnimenophthalmus. Specimens from Havana, Acapulco, and Mazatlan 

 agree perfectly. Also found on the coast of Africa and in most tropical 

 seas, (crumena, purse; 600aA/uoc, eye.) -
