in head; maxillary 3]- to 3f ; ventrals li to 2J-; highest dorsal spine 3 to 3|; second 

 dorsal ray 1| to 2. Length 23 to 36 cm. 



The following color description was taken from a fresh specimen: Back deep 

 blue, with faint traces of cross-bars. Snout and opercles dusky. Cheeks dusky 

 yellow, with coarse brown specks. Lower part of sides silvery, with some dusky 

 shading and without yellow. Caudals and pectorals light lemon-yellow, the caudal 

 narrowly edged with black. Pectorals with a jet-black blotch involving base and 

 axil of fin and basal portion of all except the lowest rays. Dorsal, anal and ventrals 

 orange-yellow, more or less dusky; dorsal inconspicuously margined with black.

Hemicaranx zclotcs Gilbert (Jordan & Evermann, 1898, p. 2845). 



Closely related to atrhnanus, with which it agrees in having a large jet-black area 

 on axil and base of pectorals. It differs from atrimanus in the following characters: 

 The more rounded profile of snout; the lower spinous dorsal; the longer maxillary; 

 the higher, shorter curve in the lateral line; the wider scutes, which are also fewer 

 in number; the darker coloration of body and fins. 



Head 4 to 4| in length; depth, 2f to 2|; D. VII-I, 26 to 29; A. II-I, 23 to 25; P. 20 to 22. 

 Scutes 51 to 53 (over 60 in atrhnanus). 



Body regularly elliptical, its greatest depth about in the middle of its length, exclusive of 

 caudal peduncle. Head small; anterior profile more decurved, the snout hence blunter than in 

 atrimanus; depth of head just behind eye about five-sixths its length. Jaws subequal, the tip of the lower 

 slightly projecting; maxillary narrow, not quite reaching anterior margin of pupil, about 3 J in head 

 (3j^ in atrimanus). A single series of small, close-set subequal teeth in each jaw; no teeth on vomer, 

 palatines, or tongue. Orbit considerably greater than snout, 3J to 3:* in head. Interorbital width 

 (taken at anterior margin of orbit) slightly less than orbit. Occiput with an evident carina. Distance 

 from snout to first dorsal spine greater than length of pectorals. 



Spinous dorsal very low, the highest spine considerably less than orbit (greater than orbit in 

 atrimanus). A well developed antrorse spine before the dorsal. Soft dorsal and anal similar, not 

 falcate; the rays decreasing in size from the first; the highest ray of the soft dorsal 2 to 2I in head; 

 the highest ray of the anal about 2 J in head. Dorsal and anal depressible into a sheath of scales, the 

 last 3 or 4 rays uncovered. Caudal fin wide, well forked, the upper lobe the longer, the longest ray 

 not quite one-fourth total length of body. Pectoral fin long, falcate, but much shorter than in atri- 

 manus, T,\ to 3f in body (2| to 2* in atrimamcs). Ventrals 2| to 2f in head. Scales as in atrimanus. 



Lateral line with a very strong curve anteriorly, the height of the curve 2| to 3J in its length; 

 its length 2 J to 2|- in the straight portion. The entire length of the straight portion is furnished with 

 scutes, which are very small in front and behind. The scutes are considerably wider and lower than 

 in atrimanus: the widest about one-half the diameter of orbit (about one-third diameter of orbit in 

 atrimanus) . 



Coloration much as in atrimanus, but darker and the fins without yellow. Blackish olive above, 

 dusky silvery below, top of head and snout black. Spinous dorsal black; soft dorsal and anal black, 

 except a narrow light streak at base. Caudal dark, margined with black; pectorals very dark, black 

 on inner face, the extreme lower rays light. A large jet-black blotch covers the base of the pectorals 

 and extends for about one-fifth of the whole length of the fin; the a.xil is also black. 



Four specimens were obtained in the market at Panama; none others were seen.
