uncovered; caudal fiu wide, well forked, the upper lobe the longer, the 

 longest ray not quite ^r total length of body; pectoral fin long, 3^ to 3^ in 

 body (2f to 2f in atrimanus) ; ventrals 2= to 2| in head. Scales as in atri- 

 manus; lateral line with a very strong curve anteriorly, the height of the 

 curve 2| to 3i in its length ; its length 2^ to 2} in the straight portion; 

 entire length of straight portion with scutes, which are very small in 

 front and behind; scutes considerably wider and lower than in atrimanus, 

 the widest about i diameter of orbit (about ^ diameter of orbit in atri- 

 manus). Coloration mucli as in H. atrimanus, but darker, and the fins 

 Avithout yellow; blackish olive above, dusky silvery below; toji of head 

 and snout black; spinous dorsal and the broad margins of soft dorsal and 

 anal black ; caudal dark, margined with black ; pectorals very dark, black 

 inside, tlie extreme lower rays light; a large jet-black blotch at base, on 

 each side of pectorals, extending for about 7, the whole length of the fin; 

 axil black. Closely related to Hemicaranx atrimanus. Like it, it has a 

 large jet-black area at axil and base of pectoral, and differs from it in the 

 following characters: In having a shorter pectoral, shorter ventrals, pro- 

 file of snout more rounded, a lower spinous dorsal, a shorter maxillary, a 

 higher, shorter curvcin Lateral line, wider scutes, which are less sharply 

 cariuated, and darker fins. Panama. (CeAor?/^, an imitator.) 



Page 921. Caranx crysos and Caranx pisquetus are probably distinct sjie- 

 cies, the former ranging from New York to Florida, the latter from the 

 West Indies to Brazil. 



In Caranx pisquetus the pectoral fins are very long, as in the Pacific spe- 

 cies Caranx cahallus, from which we can not separate it. The species need 

 further study.

Head 2i; depth 1|; D. VI-I, 22; A. I, 18; eye 3| in head; maxillary 2i; 

 snout li; caudal 1. Body very deep, in form much like Selene urstedii; 

 juofile very steep, almost vertical; snout slightly protruding. Mouth 

 oblique, maxillary reaching to the vertical from front of eye; gill rakers 

 7 to 27, the longest a little more than i eye. Lateral line strongly arched 

 in front, the arch IJ the straight part; plates of lateral line little dift'er- 

 eutiated; pectoral falcate, as long or slightly longer than head; A'cntrals 

 small, under base of pectorals. Color bluish above, sides silvery, fins 

 except A'eutrals and anal dusky. Hi-re described from siieciraens from 

 Jamaica about 10 inches in length. These specimens are evidently differ- 

 ent from the Northern Corner setipinnis {^Vomer hrowni), the l)ody in sjiec- 

 imens of the same length being much deeper. It corresponds to the figur 

 given by Agassiz of J'o)iier hrowni, this figure being the basis of Vomer 

 sjnxii of Swainson. Probably all West Indian records of Vomer setipinnis 

 belong to Vomer spixii. (Named for Jean Baptiste Sjdx, of Munich, natur- 

 alist and explorer. )
