 snont 3i ; maxillary 3i ; pectoral If, equals ventral ; longest ray of soft 

 dorsal 2A ; longest dorsal spine 2\ ; longest anal ray 2 ; upper lobe of caudal 

 equals bead. Gill rakers 6 -f- 15. Body ovate, compressed ; pntdle rounded, 

 slightly produced before eyes, concave over snout in some specimens, 

 straight in others ; a gentle curve from eyes to dorsal ; mouth small, hori- 

 zontal, the jaws equal; teeth in a single series, about 36 in each jaw; 

 maxillary extending to the vertical from anterior edge of orbit; snout, 

 lower jaw, and preorbital naked, head everywhere else scaled; opercles 

 with 8 or 9 rows of scales; scales on body large, somewhat crowded ante- 

 riorly; all the tins, except spinous dorsal, with scales to their edges, those 

 on caudal exceedingly small. Tip of pectoral sharply rounded, not reach- 

 ing to tipsof ventrals; ventral spine half as long as soft rays; anal spines 

 short and stout, graduated; anal elevated in front and higher than soft 

 dorsal; middle spines of dorsal the longest, about equal to highest rajs 

 of soft dorsal; upper lobe of caudal the longer. Vertebra- 9 + 16 or 

 lOH-15. Color grayish black, with paler centers to the scales; about 16 

 streaks below lateral line; sides with large faint dittuse yellowish white 

 spots; a little bluish and yellowish on sides of head; a yellow streak 

 below lower part of eye; no steel blue or bronze in life, the cohu-ation 

 much duller than in K. analogus. Pacific Coast of tropical America from 

 Guaymas to Mazatlan. Here described from Mazatlan specimens. This 

 species is rather common about Mazatlan, especially in the sluggish waters 

 of the Astillero. It reaches a length of about 15 inches, (elef/ans, ele- 

 gant, but its colors are less bright than usual in this genus, and the body 

 deeper. )
