statement is probably a mistake, since in the fignre given 
there are six. The species is nearer to proximus and va- 
rius than to toeniatus.

This species is closely allied to A., fasciatas. It is a 
trifle less slender. The general appearance is darker ; of 
the bands across the flank the three anterior occnpy the 
same positions, bnt the fonrth has given place to a longi- 
tudinal band extending back to include the caudal spot. 
The snout is one and a half times the diameter of the eye. 
In the length of the body, without the caudal, the depth 
is contained three and four-fifths times, or the length of 
the head four and two-thirds times. The middle of the 
length is below the ninth dorsal ray. The mouth opens 
forward. The jaws are equal, and the teeth are crenu- 
late in both.

This species is very close to the preceding. Aside from 
being more slender, the main dependence in distinguishing 
it is to be placed on the coloration, as the formula is about 
the same fur each. The tenth ray of the dorsal is nearly 
over the middle of the length, in which the depth is con- 
tained four and one-third and the length of the head four 
and two-thirds times. The mouth opens forward, the 
jaws are nearly equal, and the teeth are crenulate in upper 
and lower. The snout is about one and one-fourth times 
the diameter of the eye. Collected at Coary, Dutch Gui-
