FRESH- WATER FISHES OF WESTERN CUBA. 
233 
Among 32 specimens from San Antonio there are 3 distinct types, one of which may simply be the 
adult of one of the others. They are all elongate, the depth being 2.3 to 2.5 i . length. There are, in 
the first place, 4 adults measuring 1(50 to 190 mm. in length, of type B from Calabazar. They differ from 
the Calabazar specimens in having the spots along the scales larger and less regular. In two of the 
specimens the cheeks are spotted, in two others the spots are confluent into vertical or longitudinal 
streaks. In the largest some of the dorsal rays are prolonged, reaching to near middle of caudal. These 
are probably the adult of 17 specimens from 92 to 157 mm. long. In all of these, even in the smallest, 
there are spots on the cheeks, more numerous in the larger, and confluent into streaks in the largest. 
Sides irregularly spotted; lateral band more or less conspicuous as the fish is lighter or darker; there 
are traces of the usual light and dark bands in some individuals. All of these are evidently typical 
II. teiracanthus. 
There are 11 specimens, 90 to 123 mm. long, evidently modifications of II. ietracnnthus torralhasi 
from Calabazar, in which, except one very dark specimen, the lateral band is very conspicuous. Ver- 
tical bands quite well marked except in darkest specimens. Cheeks are unspotted except in one 
individual which has faint spots; sides without small dark spots.

D. xv, 11; A. iv, 8; scales 27; pores 17 + 10; depth a little more than 2.5; depth of caudal 
peduncle 2.5 in head; head 2.7 in the length. Shape and general characters of Heros teiracanthus 
from the same place, differing in the color and the notably larger eye, as compared with specimens of 
II. teiracanthus of the same size. Eye 3.7 in head (4.6 in II. tetracanthus of the same size) ; 1 in inter- 
orbital (1.5); 1.25 in snout (1.7); preorbital five-sevenths of eye; snout 3 in head; highest dorsal
