moderately depressed, its greatest width about equal to its length 

 without snout; interorbital space 2.0 to 2.1 in head; snout broadly- 

 rounded, 2.7 to 2.9 in head; eye lateral, 7.0 to 7.2 in head; mouth 

 moderately broad, its cleft extending somewhat beyond posterior nos- 

 tril, its width at angles 1.95 to 2.1 in head; teeth pointed, in a broad 

 band in each jaw, and a similar one on vomer and palatine, the vo- 

 merine teeth well separated on median line, but continuous with the 

 palatine teeth in the three specimens at hand (not as described and 

 figured by Eigenmann and Eigenmann (1890, p. 51, fig. 7) or by 

 Evermann and Radcliffe (1917, p. 31), one of whose specimens is at 

 hand); gill rakers short, 3 on upper and 10 on lower limb of first 

 arch in one specimen; upper surface of head smooth, fontanel produced 

 forward as a deep groove sometimes nearly to posterior margin of 

 eye; occipital plate narrow; origin of dorsal about length of snout 

 behind base of pectoral spine, distance anterior to dorsal 2.6 to 2.7 

 in length; dorsal spine slender, without definite barbs, 1.35 in head; 

 adipose fin large, its origin over or a little in advance of that of anal, 

 its base 2.5 to 2.8 in head; caudal fin long, deeply forked, the upper

lobe the longer; anal fin with rather deeply concave margin, the an- 

 terior rays reaching well beyond tip of posterior one if deflexed, 

 its base 2.0 to 2.25 in head; ventral rather large, reaching origin of 

 anal, inserted about equidistant from base of pectoral spine and 

 middle of base of anal; pectoral failing to reach base of ventral by 

 about length of snout, the spine distinctly barbed distally on outer 

 margin, 1.4 to 1.8 in head. 



Color of preserved specimens blackish above, pale silvery under- 

 neath, middle of side with a silvery to slightly reddish band about as 

 wide as eye, becoming obscm-e anteriorly; fins mostly blackish, the 

 pectoral with pale inner margin, the dark middle rays of ventral with 

 pale margins, posterior half or so of anal pale. 



The Mission secured two specimens, 285 and 325 mm. (223 to 245
