5((i) 
Rather more stout than the preceding, but similar in 
general outline and markings. Mouth opening obliquely 
upward and forward, lower jaw longer, lower teeth trun- 
cate, upper crenulate. Snout about one and one-fifth times 
as long as the eye. Length of head and depth of body 
nearly eqnal, about two-ninths of the total length, without 
the caudal. The eighth ray of the dorsal is close upon the 
middle of the length. The row of scales from the first ray 
of the ventral toward the dorsal strikes the hindmost ray 
of the latter. 
Brownish, rather dark, with a band of darker from snout 
to tail below the lateral line. 
Closely allied to A. loeniatus from which it may be dis-

of scales lighter and silvery, belly silvery. A brownish 
band from snout to tail, below the lateral line, endinsf 
in a black spot. The band is rather indistinct, and of- 
ten obsolete. On the flank there is a transverse band of 
brownish behind the base of the pectoral, a second from 
base of dorsal to that of ventral, a third behind the dorsal, 
and a fourth in front of the soft dorsal. The color is us-
