220(a). TILL ARIL'S PRICEI, Eutter. 



B. 8; D. I, 6; A. 22 or 23; C. 17; P. I, 9; V. 8. Head 3fc to 3| iii body; 

 eye 5 to 7 in head ; snout 2f ; maxillary 5| to 6. Maxillary barbel very 

 long, reaching beyond the pectoral 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, pectoral 

 spine 2 to 3 in head, with about 12 distinct hooked serrai 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 deeply 

 forked. Lateral line faint. This species differs from V. dugesii (Beau) in 

 having very prominent serrations on the pectoral spines, the types of dugesii 

 having the pectoral spines without seme. 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 papill.e along the lat- 

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

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



Villarius pricei, BUTTER, Proc. Cal. Ac. Sci., ser. 2, vol. vi, 3896, 257, San Bernardino 

 Creek, a tributary of the Yaqui River, southern Arizona. (Type, No. 4826, L. S. Jr. 

 Univ. Mus.)

 it is an important food-fish.

 The two species are confused in the description of C. Jatipitinis given by 

 us. They may each be described as follows:

Head 4 ; depth about 5^ ; eye high up and small, 5 to 7 in head, 3 to 34 

 in snout, 2 to 2| in interorbital space; interorbital width 2? 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 flat above, its greatest 

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

 Least depth of caudal peduncle 4| 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 -J- the length of the first ray ; origin of dorsal fin nearer 

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

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

 upper lip, the smallest above; lower lip large, incised to its base, with
