mandibular articulation nearly to gill opening. Teeth in lower jaw 

 small, but distinctly visible ; in upper jaw larger toward tip of maxil- 

 lary, where they are directed forward. Opercle narrow, scarcely as 

 wide as exposed portion of preopercle, the margin moderately oblique, 

 not wavy. Front of dorsal midway between base of caudal and front of 

 pupil ; base of ventrals midway between origin of anal and articulation 

 of mandible ; origin of anal behind last ray of dorsal. Scales closely 

 adherent, rather thick and firm. Olivaceous, the dorsal region with black 

 specking; a silvery band along middle of sides, very narrow anteriorly, 

 but increasing in width to opposite anal fin, where it is as wide as eye ; 

 snout and margin of caudal lobes dusky. Length 3 inches. Santa Mar- 

 garita Island, Lower California, (cultratus, knife-formed.)

Head 4i; depth 4f. D. 13; A. 23; scales 40. Head short, nearly 

 as deep as long ; eye large, much longer than the blunt snout, which pro- 

 jects considerably beyond the lower jaw. Gill rakers numerous, slender,

 dible. Lower lobe of caudal the longer ; dorsal inserted midway between 

 caudal and front of eye. Very pale olivaceous, translucent, with some 

 dark points, and a silvery lateral band not as wide as the eye. Length 3
