pectoral origin, and depressed tip not quite to soft dorsal origin, 

 which midway between front or hind nostril and caudal base. Soft 

 dorsal nearly uniformly low. Anal inserted about midway between 

 ventral origin and caudal base, second spine enlarged, 2| to 2f in 

 head. Pectoral and ventral about equal, 1^ to 1^ in head. In 

 alcohol faded largely uniform brownish, centers of scale rows slightly 

 darker. Lower surface with traces of silvery. Spinous dorsal and 

 caudal tinged dusky. Length of larger 203 mm. (caudal end dam- 

 aged) . 



Cope originally separated these two examples as varieties of U. 

 hroussoneii Cuvier, the smaller and longer example without brown 

 vertical bars and the larger deep one with nine vertical bars,

Head 3; depth 2t; D. IX, 10; A. II, 9; scales 23 in 1. 1. to caudal 

 base and 2 more on latter; 2 scales above 1. 1. to spinous dorsal origin 

 and 6 below to anal origin; 4 predorsal scales; snout 2f in head; 

 eye 4|; mouth 4f; interorbital 4f. Body well compressed, ovoid, 

 deepest about middle of pectoral. Caudal peduncle compressed, 

 least depth 2| in head. Head compressed, upper profile little more 

 inclined. Snout about long as wide, muzzle compressed. Eye 

 elevated, hind edge about midway in head length. Pupil ellipsoid. 

 Mouth gape slightly inclined forward, about f to eye or not quite 

 to front nostril. Three canines on outer face of upper jaw, all flaring 

 out, front pair close together and directed forward. Ten oblique 

 rows of teeth along each side of lower jaw. Front nostril about 

 half an eye-diameter before eye, with fleshy filament about | same. 

 Interorbital slightly depressed concavely in front, slightly convex 

 behind. Rakers 4 + 12 flexible points, j of filaments and latter 

 about 4| in head. Tubes in 1. 1. arborescent. Row of 5 large scales 

 on cheek. Dorsal spines quite pungent, mostly uniform, second
