About thirteen pre ventral scales, an equal number of predorsal scales; maxillary- premaxillary border three times in the head, maxillary about two-thirds as long as the eye. Premaxillary with six to eight teeth; maxillary with two to four, mandible with nine to ten; mouth small, the maxillary scarcely reaching to eye; pectorals reaching vcntrals; origin of dorsal nearer caudal than to tip of snout. Anal and caudal sometimes margined with dark; chromatophores on the dorsal rays; outer pectoral ray sometimes dark; no humeral spot. Anal in the male with four, rarely more, hooks on all the rays but the first. Fig. 7.

M. 28 mm. to base of caudal. two and the last, the hooks strongest on the posterior rays and on the middle third of the rays. While quite similar in general appearance to dentaius, this species differs in many ways. It is smaller, deeper, has fewer scales, much fewer maxillary teeth, a smaller mouth and different color. The anal in the male with hooks on practically all the developed rays, is quite different from that of A. dentatus, which has hooks on only the rays of the lobe. 9. Aphyocharax avary Fowler. Aphyocharax avary Fowler, Proc. Acad. Nat. Sci., Phila., 1913, p. 532. Known only from the type, 54 mm. long, from the Madeira River about two hundred miles east of Long. 62° 20', Brazil. Head ; depth ; D. 13; A. 17; scales forty-two, of which eleven are.
