THE GYMNOTID EELS OF TROPICAL AMERICA. 185 
These fishes are of a dull gray color in alcohol and of the same general shape as the 
other members of this subfamily. From the injured surfaces all were regenerating 
caudal fins after the fashion just mentioned in the case of miilleri and bonaparti. 
In no case was the new caudal confluent with the old anal fin, and in the more ad- 
vanced regenerations there was a small caudal peduncle. Figure 27 shows a series 
Fia. 27. Regenerated Tails of Sternarchus hasemani Ellis, Santarem. 
of the regenerated fins of hasemani. Steindachner notes an interesting specimen 
of Sternarchella (Sternarchus) schotti which has regenerated a second caudal fin 
above the true caudal. His figure is copied in Figure 28.
