Head four and one half to five times in the length, without the caudal. 
Interorbital space wider than that in A. mécrolepis ; frontal shield, around 
the eye, more regularly rounded and less angular forward. The ocular 
shield is higher than that of A. Dowi’, consequently the upper half of the eye 
does not look quite so directly upward. 
Back olivaceous or greyish brown to yellowish, in many cases with a 
light streak from the dorsal to the back of the head where the line branches 
toward each eye. Flank with three to five darker longitudinal bands, two 
or three of which are usually more distinct and complete than the others. 
Two of the bands are sometimes joined above the vent. On the caudal 
section there are from two to five bands, more often three with broken 
pieces ; at the base of the caudal the upper bands either turn downward and 
join the lower or break in pieces forming vertical spots and bars. Fins uni- 
form to brownish, dusky or clouded, pectorals rather darker. Lower surface 
yellowish, the yellow color extending more or less up the flanks. All the 
data given above in discussing the genus concerning the embryo relates 
especially to this species. 
The specimens under examination were collected at Trinidad, Surinam, 
Para, Curuca, Lake Saraca, Serpa, and Arary. The largest are about ten 
inches in length.

On an average specimen the length of the head is about two ninths of 
the length of the caudal, or three sixteenths of the total. The crown is less 
flat and the interorbital space is narrower than in the other species. The
