 25 + 27-28. 



Head four and one half to five times in the length, without the caudal. 

 Interorbital space wider than that in A. microlepis ; frontal shield, around 

 the eye, more regularly rounded and less angular forward. The ocular 

 shield is higher than that of A. Dowii, 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 Avith 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 spiice is narrower than in the other species. The
