The genera and species of characins described in the present paper 

 were collected by Mr. John D. Haseman for the Carnegie Museum 

 between November, 1907, and February, 1910, in various parts of 

 eastern and southern Central South America. Descriptions of other 

 new characins found by the same naturalist-explorer will be published 

 in subsequent numbers of these Annals.

 with three points in the angles of a nearly isosceles triangle, the middle 

 point, which is also the anterior one, much heavier; maxillary with 

 three to five teeth, the first two or three of which are directed out- 

 ward ; each ramus of the mandible with four large teeth, the first 

 three directed outward, the fourth, and one or more smaller ones 

 following it, directed upward; the larger teeth of the lower jaw heavy, 

 conical, with a minute cusp on each side. Lateral line complete;
