These fishes are of a ckill 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

of the regenerated fins of haseviani. 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.
