NOTES ON SOME FISHES FROM THE CANAL ZONE/ 



BY BARTON WARREN E VERM ANN AND 

 EDMUND LEE GOLDSBOROUGH. 



]\Ir. August Busck of the Division of Entomology, U. S. 

 National Museum, spent several weeks in the Canal Zone in 

 the early part of 1907, studying the mosquitoes of that region. 



These studies naturally led him to make some ohservations 

 on the fishes, particularly the smaller freshwater species, with 

 reference to their feeding habits. Specimens of a number of 

 species were collected and preserved and later turned over to 

 the Bureau of Fisheries for identification. 



Later (in 1908), at the instance of Mr. Busck, a second con- 

 siderable collection was received from Mr. Allan H. Jennings, 

 Office Chief Sanitary Inspector, Ancon, Canal Zone. 



The localities represented in the collections made by Mr. 

 Busck are as follows: 



1. Rio Boqueron. This stream is one of the headAvaters of the 

 Chagres River. It was examined at a point in Colombia near 

 the coast and al)out 40 or 50 miles from the Canal Zone. 

 At that place the Boqueron is a small stream not over 40 feet 

 wide and never getting much wider, although subject to great 

 and sudden floods. At one time it rose 9 feet in 2 hours. 



Dynamite was used in collecting in this stream, in which 

 small fishes were very abundant. Mr. Busck collected at this 

 place in May, 1907. 



2. Taboga Island. This island is on the Pacific side about 10 

 to 15 miles due east from Panama. 



The specimens from this place were obtained from tidepools 

 July 4, and all belong to saltwater species.
