The following counts were made: Gill rakers on first gill arch of 
one side 2+5, short and rudimentary; scale rows on side of body 
from gill opening to base of caudal fin 42; scales above lateral line 
71% and below lateral line 114; scale around caudal peduncle 14; scales 
in front of dorsal fin 1914; dorsal rays 111, 8; anal 111, 10; pectoral 15; 
pelvics 9; pharyngeal teeth on one side 4:3: 2. 
This new species has a compressed body; no barbels; the maxillaries 
extend to below rear of eye; the eye is equal to the length of the 
snout, and about 3 times in the head; the origin of the dorsal fin is 
farther back than usual as the distance from the origin of the dorsal 
fin to mid-base of caudal fin equals the distance from origin of dorsal 
to anterior edge of scaled portion in front of dorsal; mouth large, 
oblique, when closed a small symphyseal knob on lower jaw fits into 
a notch in tip of snout, the latter not projecting in front of jaws; 
the inner edges of the lips are finely plicate; the gill membranes ex- 
tend a short distance forward before becoming narrowly joined to 
the isthmus; suborbital bones greatly expanded covering 44 or more 
of the cheeks; interorbital space almost flat, a trifle convex; dorsal 
profile almost straight, a little convex in front of eyes; the large 
axillary scales of pectoral and pelvic fins have an enlarged keel, this 
scale being connected with the fin by a dermal membrane on both pec- 
toral and pelvic fins; mandible with numerous pores not arranged in 
lines; premaxillary protractile; lateral line below axis of body, com- 
plete; the almost parallel striae on scales slightly divergent. 
Color (in alcohol) .—Silvery on sides; pale tan above; on level of 
lower half of eye anteriorly but along mid-axis of caudal peduncle is 
a row of 13 oval blackish spots, the largest smaller than the eye and 
on opercle another spot, thus totaling 14; anteriorly below and be- 
tween the black blotches, just above the lateral line are 9 smaller 
blackish spots; upper margin of eye pigmented; posterior dermal
