THE AMERICAN NATURALIST [Vol. XLI 



make new mistakes. With the Hmited material at his command 

 it is to^ be regretted that Dr. Fowler has not confined himself 

 largely to figuring and describing, instead of bestowing new 

 generic and subgeneric names with princely liberality and aban- 

 don. While he has helped by his figures and descriptions, he 

 has in large measure increased, rather than lightened, the burdens 

 of his successors. 



The new genera and subgenera proposed by Dr. Fowler (24 in 

 number) are consecutively numbered in the following notes: 



1. — Ophiocephalops. This is an exact synonym of Hoplery- 

 thrinus of Gill. 



2. — Copeina, a new name for the genus Holotaxis of Eigen- 

 mann, not Cope. This is probably a valid name. 



3. 4, 5. — Curimata is used for Curimatus, although the latter 

 is the earlier form. The genus is divided into the subgenera, 

 (3) Cyphocharax, (4) Steindachnerina, (5) Peltapleura, and 

 Curimata. The known species of the genus are not distributed to 

 their respective subgenera and there is no evidence produced in 

 this paper demonstrating that these subgenera are valid or that 

 Dr. Fowler is able to delegate the species to their proper sub- 

 genera. Cyphocharax and Curimatus are probably valid. It 

 is to be hoped that Dr. Fowler will distribute the species for us. 



6. — Eigenmannina, a new generic name for Anodus melano- 

 jjogon is apparently valid. 



7. — Chilomyzon is a new subgenus of Prochilodus, distin- 

 guished by having 33-38 scales in the lateral line, whereas Pro- 

 chilodus is said to have 40-60. This division is unfortunate 

 since P. hunieralis has 33 scales, vimhoides 35-37, oligolepis 36-38; 

 Imigirostris 38-39, rnagdalenae 40-41, cephalotes 41, a^per and 

 hartii 41-42, brevis 41-43, rubrotaeniatns 44, etc., to the end of 

 the series. The new species, Prochilodus theraponura and amazo- 

 nensis are very probably two stages (2^ and 4| inches long) of 

 the common P. insignis. 



8. — Hemiodopsis, a subgenus of Hemiodus, distinguished by 

 having 100 scales. Since the other species of Hemiodus have 

 58-85 scales this division may be convenient. 



9. — Pithecocharax is substituted for Anostomus because he 

 thinks the latter is preoccupied by Anastomus Bonnaterre 1790.
