THE SHORE FISHES OF PERU 125 



Santa, near Chimbote. A third specimen (U.S.N. M. No. 77693), 

 350 mm. (273 mm. to base of caudal) long, taken at Callao by R. E. 

 Coker, also is at hand and is included in the proportions given. This 

 catfish is readily recognized by the reddish silvery lateral band. 



Range. — Altata, Sinaloa, Mexico; Panama Bay; and Peru. Re- 

 ported as abundant on the coast of Peru by Steindachner (1875, p. 34).

Head 3.25 to 3.6; depth 4.2 to 4.4; D.I, 7; A. 17 to 19; P.I, 9 or 10. 



Body rather robust, its depth exceeding its width at origin of dorsal 

 by a half to a whole diameter of eye, tapering posteriorly; caudal 

 peduncle rather strongly compressed, its depth 3.25 to 3.55 in head; 

 head not especially broad, its greatest width slightly exceeding its 

 length without snout; interorbital space quite flat, 2.0 to 2.05 in head; 

 snout not strongly depressed, its sides nearly vertical, very broadly 

 rounded anteriorly, 2.6 to 2.7 in head; eye large, elongate, lateral, 

 5.75 to 6.25; mouth broad, arched forward gently, its width at angles 

 2.5 to 2.7; teeth quite pointed, the band on upper jaw (premaxillary) 

 not extending quite to angles of mouth, continuous, the band on lower 

 jaw narrower, and reaching farther back, well separated on median 

 line; vomerine and palatine teeth less sharply pointed, vomerine 

 patches well separated on median line in some specimens, rather 

 close together in others, scarcely separated from the much larger 

 palatine patches; gill rakers scarcely half length of eye, 5 or 6 on upper 

 limb and 10 or 11 on the lower one of first arch; upper surface of head 

 often rather smooth, sometimes granular, no ridges; fontanel groove 

 generally extending forward to opposite posterior margin of eye, and 

 backward nearly but not quite to occipital plate; this plate fully as 

 broad as long, with a sharp median keel; origin of dorsal about 

 length of snout behind base of pectoral spine; distance anterior to 

 origin of dorsal 2.5 to 2.8 in length; dorsal spine only slightly rough on 

 anterior margin, its posterior margin with small barbs, failing by 

 diameter of eye to reach tips of longest soft rays, 1.3 to 1.6 in head; 

 adipose moderately large, beginning a little behind vertical from
