2(515. OPISTH06N1THU8 LONCHURUM, Jordan & Gilbert. 



Head 3; depth 4|. D. 25; A. 15; scales 67. Head moderate; snout 

 very short, shorter than pupil; eye 3 in head; maxillary 1 in head, 

 rather narrow; lower jaw included; vomer with 5 rather large teeth. 

 Longest dorsal spine about as long as head, slightly higher than soft rays ; 

 caudal long, the middle rays scarcely shorter than head ; longest anal rays 

 li in head; pectoral little more than head. Scales moderate. Oliva- 

 ceous; margin of upper lip with a narrow black stripe; caudal with 3 

 dusky bars; color of rest of body uniform. Gulf of Mexico, in deep 

 water. Two specimens known, taken from the stomach of a Red Snapper 

 at Pensacola, Florida. The species resembles Gnathijpops mystacinus, 

 found in the same waters, but the latter species has smaller scales. 

 (hoy XTJ, lance; ovpd, tail.) 



Opisthognathus lonchurus, JORDAN & GILBERT, Proc. U. S. Nat. Mus. 1882, 290, Snapper 

 Banks, off Pensacola, Florida (Type, No. 29671. Coll. Jordan & Stearns) ; JORDAN 

 & GILBERT, Synopsis, 943, 1883. 



2616. OPISTHOGNATHUS PUNCTATUM, Peters. 



D. 28 ; A. 18. Body moderately elongate ; scales very small, about 125 

 in lateral line. Dorsal spines continuous with the soft rays. No vomerine 

 teeth. Maxillary very long, extending slightly beyond head. Head 

 everywhere finely speckled with black, the body more coarsely and 

 irregularly spotted; pectoral finely and closely speckled, its edge plain; 

 ventral fin dusky, similarly marked; dorsal without large black blotch, 

 finely spotted, the spots behind gradually forming the boundaries of white 

 ocelli, the base of the fins having rings of white around black spots, the 

 upper part with dark rings around pale spots; caudal with pale spots, its 

 edge, like that of the dorsal, somewhat dusky, not black; anal with a 

 broad, blackish edge, and with dark spots, those near the base of the fin 

 largest; lining membrane of maxillary with the usual bands of white and 

 inky black. Mazatlan. Only the type of this species is yet known, this 

 description having been taken by us from the original specimen. It bears 

 considerable resemblance to Gnatliypops rhomalea, which is found in the 

 same waters, differing in the generic character of the dilated maxillary. 

 (punctatus, spotted.)

 snout very short, about as long as pupil; eye large, 4 in head; maxillary 

 reaching slightly past edge of preopercle, but not to end of head, its 

 length contained 3| times in length of body. Teeth rather strong, wide 

 set, forming 2 distinct series, directed backward, especially in the upper 

 jaw; lateral teeth of lower jaw largest; a single vomerine tooth. Gill 

 rakers long and slender, nearly 20 below angle. Scales very small.
