concave; caudal peduncle well compressed, 2.7 to 2.9 in head; snout 

 rather pointed, 4.1 to 4.6; eye large, 3.5 to 4.2; interorbital 5.1 to 5.6; 

 mouth large, oblique; lower jaw projecting strongly, extending into 

 dorsal outline; maxillary broad, with a distinct supplemental bone, 

 reaching below posterior margin of pupil, 2.0 to 2.25 in head; teeth 

 villiform, in bands on jaws, vomer, and palatines; some of the outer 

 ones in upper jaw slightly enlarged; gill rakers rather long and slender, 

 those at angle about three-fourths the length of the large eye, 19 to 21 

 on lower and 9 to 12 on upper limb of first arch; scales moderately 

 ctenoid, reduced in size, anteriorly above lateral line and on head, 

 extending forward on snout, present also on maxillary and mandible; 

 dorsal spines strong, the fourth to sixth of about equal length, the 

 others shorter, the fourth 2.4 to 3.0 in head; caudal fin rather deeply 

 emarginate, the upper lobe slightly the longer; anal spines strong, 

 graduated, the second 3.1 to 4.1 in head; ventral inserted a little 

 behind base of pectoral, reaching to or a little beyond vent, with a 

 rather strong spine, 2.5 to 3.0 in head; pectoral inserted well in ad- 

 vance of origin of dorsal, reaching to or somewhat beyond tip of ven- 

 tral, rather pointed, the longest rays being in upper part of fin, 1.5 to 

 1.6 in head, 3.8 to 4.0 in length. 



Color brownish, somewhat lighter above than below; lateral line in 

 a conspicuous dark streak, fins of about same color as adjacent parts 

 of body, except ventrals which are darker, especially toward tips. 



This species is described here from five specimens, 180 to 350 mm. 

 (142 to 280 mm. to base of caudal) long, collected by R. E. Coker at 

 Ballestas Island, Chincha Island, Callao, Mollendo, and Paita. 

 Although the Mission did not furnish specimens, the report (1943, 

 p. 279) states that examples were taken with a trammel net at Lobos 

 de Tierra and at Lobos de Afuera. The very large eye and the dark 

 streak along the lateral line readily distinguish this species from other 

 local serranids. The name "ojo de uva," according to Evermann 

 and Rad cliff e (see reference above), is used also for Conodon serrifer. 



According to the report of the Mission (1943, p. 279) this fish is of 

 some commercial value. It is caught with hand lines over rocky 

 bottom, chiefly from Zorritos to Paita. The average length attained 

 is said to be about 300 mm. 



Range.— Co&sts of Peru and Chile. 



Genus CRATINUS Steindachner, 1878 



Body quite elongate, little compressed; head low, scarcely deeper 

 than broad; mouth large, oblique; lower jaw projecting strongly; 

 teeth in jaws in bands, some of the teeth in each jaw enlarged, forming 

 small canines; vertical margin and angle of preopercle serrate, the 

 horizontal margin mostly unarmed; the serrae at angle little enlarged; 

 gill rakers rather short, about 12 to 15 on lower limb of first arch;
