p. 334, the present species differs in its slightly longer anal, greater depth, 
fewer scales. It is more compressed, the pectoral region deeper, the maxil- 
lary more vertical, not extending back so far relative to the eye. It re- 
sembles more in appearance the monotypic genus Prionobrama, Prionobrama 
madeire Fowler, figured in Proc. Philadelphia Acad. Sci. for 1913, p. 536. 
It is less deep than this latter with larger scales, fewer anal rays and cusped 
instead of simple teeth. Possibly the dental difference is given undue weight 
in placing analis in Aphyocharax rather than Prionobrama; it is allied to 
filigerus, but resembles very little other species of Aphyocharax with which 
it has been compared.
