Mouth large, the gape 2f iu head. Eye moderate, 2 in snout, a little 
behind the middle of the gape. Teeth pointed, fixed, those in jaws 
biserial, those on vomer in one series. Pectoral in head; dorsal be- 
ginning well in front of its tip. Tail a little longer than body. Paciric 
(and Atlantic?) coast of Tropical America; abundant southward; north 
to Southern California [fide Cooper).

583 {h). O. macrurus Poey. 
Uniform light olive, the back closely punctate, but not dark; fins all 
pale, the dorsal and pectoral without dark shades. Body not very 
slender. Head pointed, the upper jaw projecting. Eye large, more 
than half snout, placed above middle of gape. Gape 2§ in head. 
Teeth subequal, short, slender, and sharp, more or less directed back- 
wards; all of them biserial; no canines. Nasal tubes short, inconspic- 
uous. Tail twice length of rest of body. Head slightly more than 
half trunk, nearly 9 in total. Pectorals long, 2^ in head; dorsal begin- 
ning opposite anterior third of pectoral; distance from snout to front 
of dorsal 2^ in distance to vent. Gill-openings small, rather near to 
gether. L. 15 inches. Cuba to Texas. Closely allied to 0. parilis 
(Rich.), with which it is identified by Dr. Giinther; but that species 
has very long nasal tubes.

.583 (c). O. clirysops Poey. 
Light olive-green; vertical fins edged with black; tip of pectoral 
broadly dusky. Teeth all biserial, none of them very large or canine- 
like. Head conical, the snout short but rather sharp. Mouth rather 
large, its gape about 2f iu head; jaw8,and top of head with numerous 
dark-colored pores. Dorsal beginning a little before tip of pectoral. 
Lateral line of rather coarse pores. Length of head and body about 
2^ times iu total length. West Florida to Havana, in rather deep 
water. The reproductive apparatus in this species in both sexes re- 
sembles that of ordinary fishes, the ovaries in the female being very 
large, with the eggs exceedingly numerous.
