D. 10-11 ; A. 11-10 ; V. 6 ; P. 15 ; LI. 26-27 ; Ltr. 8 ; Vert. 13 + 13. 



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 L. crystallodon has spots only toward the base of the caudal, around the 

 black spot usually ending the median series.
