Form moderately elongate and compressed, depressed on head and nape. 

 Head as wide as deep, length equal depth of body, less than one third of the 

 length from snout to base of caudal ; crown broad, very little ai'ched. Snout 

 shorter than eye, blunt, broadly rounded ; chin steep. Mouth moderately 

 large, opening directed upward ; lower jaws longer ; upper short, protrac- 

 tile. Eye large, longer than snout, one third of head, two thirds of fore- 

 head. Dorsal origin about midway from occiput to base of caudal, or half 

 way from snout to end of caudal. Anal origin below fourth or fifth ray of 

 dorsal. Ventrals small, not reaching anal. Pectorals hardly reaching a 

 vertical from the bases of the ventrals. Fins rounded. Caudal deep, sub- 

 truncate to slightly concave on the hind margin, neai'ly as long as the head. 

 Ventrals with six rays, apparently, are rare. 



Silvery, brownish on the upper half of the body and head. With nine to 

 a dozen narrow brownish bands across the flank ; the hindmost commonly 

 including a small spot of blackish at the root of the caudal. Frequently the 

 vertical bands are so short that they may be described as a series of vertical 

 spots along the middle of the side. Under each scale of the flank, specimens 

 from Venice show one to several short lines that from scale to scale form 

 four or five longitudinal streaks of whitish. On these specimens the trans- 

 verse bars extend farther toward the median lines of back or belly than on 

 the species proper, which is the principal reason for separating them under 

 the variety name fasdaia.
