B. 8; D. I, 6; A. 22 or 23; C. 17; P. I, 9; V. 8. Head 3+ to 34 in body; 

 eye 5 to 7 in head; snont 2f; maxillary 5^ to 6. Maxillary barbel very 

 long, reaching beyond the i)ectoral spine, in the adult about to its tip 

 when depressed, 3 to 4 times as long as the barbel at nostril. Origin of 

 dorsal midway between snout and middle of base of adipose fin; pecto- 

 rals inserted halfway between snout and ventrals ; longest dorsal ray 6 

 to 7 times in length of body ; spine of dorsal longer than its base, equal 

 to base of adipose fin; longest pectoral ray about half of head, pectoi'al 

 spine 2t} to 3 in head, with about 12 distinct hooked serr;o behind, these 

 fewer and somewhat smaller in the young; base of anal 3 times in its dis- 

 tance from snout, its longest ray equal to length of ventral; caudal dee])ly 

 forked. Lateral line faint. This species difiers from F. diujesii (Bean) in 

 having A^ery prominent serrations on the pectoral spines, the types of (higesH 

 having the iiectoral spines without serne. We have examined a specimen 

 of dugesii, 4 inches long, from Salamanca, Mexico, which is in the type basin ; 

 it has the cirri minute and light in color, a row of papilbe along the lat- 

 eral line, and the pectoral spines with 4 or 5 degenerate serra". (Named 

 for William Wightman Price, who collected the type specimen.)

 The two species are confused in the descrii)tiou of ('. JatipUmia given by 

 us. They may each be described as follows:

Head 4; de])th about 5^; eye high up and small, .5 to 7 in head, 3 to 3A 

 in snout, 2^ to 2J in interorbital space; intororbital width 2f in head. 

 D. 14 or 15; A. 7; scales 19 or 20-89 to 102-16 to 18, 46 to 50 transverse 

 rows in front of dorsal fin. Head depressed and Hat above, its greatest 

 depth 1* in its length, the depth below lower edge of orbit 3 in its length. 

 Least depth of caudal peduncle 4i in head, or 3^ in its own length. Fins 

 very large, the dorsal with its upper margin concave; ventrals and pec- 

 torals rounded; dorsal as long as its longest ray, 1^ in head, its last ray 

 a little less than I the length of the first ray ; origin of dorsal fin nearer 

 tip of snout than base of caudal; ventrals not reaching quite to vent, 1| 

 in head. Muzzle not projecting; about 6 rows of short, thick papilbe on 

 upj)er lip, the smallest above; lower lip large, incised to its base, with
