about deep as wide, upper profile deeply concave over eyes. Snout 

 broad, convex, length f its width. Eye small, ellipsoid, high, hind 

 edge at first | in head. Teeth fine, in bands in jaws, inner row in 

 each enlarged little. Maxillary reaches eye. Lower jaw well pro- 

 truded. Nostril small, inconspicuous, near snout edge. Interorbital 

 broadly convex, elevated behind. Preopercle with strong spine down 

 and forward. Gill-opening forward last | in head. Rakers 2+6 

 low knobs, and filaments about equal eye. Scales largely uniform, 

 except along body edges where small and crowded. Also small on 

 caudal base, predorsal, top of head and breast. Snout, preorbital 

 and jaws naked, head otherwise scaly. About 15 rows of cheek 

 scales. Dorsal spines fine, slender, fin inserted much neai-er hind 

 opercle edge than soft dorsal origin. Latter little nearer hind opercle 

 edge than caudal base, rays elevated gradually to last, which longest. 

 Anal similar, only its insertion little back. Pectoral long, pointed, 

 reaches vent. Ventral pointed, | to vent, ^"entral papilla long as 

 eye. Color in alcohol largely dark brown, mottled obscurely and 

 finely with darker. Dark brown streak from behind eye to upper 

 opercle edge, another from lower eye edge to median preopercle 

 edge. All fins except first dorsal finely barred with narrow dark 

 brown wavy lines. First dorsal pale, with about 5 dark lines ap- 

 parently, though very faint. Iris slaty. Length 128 mm. (caudal 

 end damaged). Type of C. penviger Cope, No. 10,575, A. N. S. P. 

 Cope saj^s "first dorsal with white extremity and two longitudinal 

 black bars, one along the base," though more appear present.
