CHARACINIDAE FROM VENEZUELA—SCHULTZ 363 
females with mature eggs being deepest, their depth about 2.6 to 3 in 
the standard length, whereas the immature are slenderer, often 3.3. 
Another character very variable with age is the number of teeth on 
the maxillary. These teeth number about 2 or 3 in the young and 
increase in number with age until about 11 are formed in the largest 
specimens. 
Hemibrycon in Venezuela, occurs most frequently in the mountain 
streams among rubble and in rock pools and less frequently at lower 
elevations.
