A. Fishes collected by Frederick C. Hartt. 



Through the courtesy of Prof. B, G. Wilder, I have been able to 

 examine the collections of South American fishes, of Cornell Uni- 

 versity. These are for the most part fresh-water fishes collected 

 by the late Frederick C. Hartt in the eastern parts of Brazil. The 

 collection is interesting in that it adds several new species and 

 extends the known habitat of others. The Nematognaths of the 

 collections have been described by one of my students in the Annals 

 of the New York Academy of Sciences (Mr. E. M. Kindle). The 

 Cichlidse have been examined by Mr. W. L. Bray and myself. The 

 Characinidas have been examined by my associate Mr A. B. XJlrey. 

 These groups are not included in the present notes, which embrace 

 all but these.
