D, 10-11; A. 11-10; V.6; P. 15; Ll. 26-27; Ltr. 8; Vert. 134-18. 
Body stout, moderately compressed and elongate, depth little more than 
length of head. Head about three and one third times in the length to the 
caudal base, crown nearly flat. Snout shorter than the eye, blunt; chin 
steep. Mouth moderate, directed obliquely upward; lower jaws longer ; 
upper short, protractile. Eye large, one third longer than the snout, one 
third of head, three fourths of forehead. Dorsal origin midway from head to 
base of caudal or half way from snout to end of caudal. Anal origin below 
third or fourth ray of dorsal. Ventrals small, not reaching anal. Pectorals 
short, not reaching bases of ventrals. Fins rounded. Caudal convex. 
Silvery, brownish on back, brown on top of head, with numerous small 
spots of brownish, arranged in three or more, more or less irregular, longitu- 
dinal series, the median of which, on the lateral line, commonly ends in a 
black spot on the middle of the base of the caudal. On some this median 
series is entirely composed of blackish spots. Rarely the spots are some- 
what confluent into longitudinal bands. Brownish specimens show a longi- 
tudinal band of silvery along the middle of the flank. The form described 
as LL. erystallodon has spots only toward the base of the caudal, around the 
black spot usually ending the median series.
