mily of the Gharacidae, ubiquitous in South America, being 
rather closely allied to the Tetragonopterinae and the Bryco- 
ninae. They are compressed, deep fishes, with a series of 
median spines along a greater or less part of the ventral 
surface. The dorsal fin is longer than in most of the other 
South American characins, and reaches its maximum Jength in 
Myleus pacu, which has twenty-seven dorsal rays ». (p. 226 ). 
« All of the species of the Serrasalminae have an evil 
reputation as carnivores. — Stories of their depredations, from 
cutting up fish-nets, mutilating other fishes, taking of fin- 
gers or toes or otherwise mutilating man or beast, to ske- 
letonizing a horse and rider, wlio tried crossing a stream 
where they abound, are found in many boocks of travel, 
from that of Fray Pedro Simon in 1535 to that of Colonel 
Thecdore Roosevelt in 1914 (p. 227 ). 
The Serralminae can readily be distinguished from the 
Mylinae by the teeth. The former have a single series of 
teeth in each jaw. The latter have two series of teech in 
the premaxillary and frequently a pair of teeth behind the 
front series of the lower jaw.» (p. 235)... Gastropristis
