to many Venezuelans, chief among whom are Coronel All 

 Gomez, Don Carlos Delfino, Dr. Juan Iturbe, and a most 

 admirable guide and compadre, Agapito Blanchar. It is a 

 pleasure also to acknowledge the great help received from the 

 writings and general advice of Dr. C. H. Eigenmann, whose 

 Stores ofc wisdopj relating to South America and its fishes were

 insects; Dr. H. J. Van Cleave, acanthocephalans; Dr. N. A. 

 Cobb, nematodes; Mr. Bryant Walker, molluscs; Dr. Ruth

The equipment used for fishing was as follows: 1 9-inch 

 dip net with 6 ft. handle; 1 seine 50X4 ft., Y in. mesh,* with 

 4X4 bag in middle; 1 seine, 30X4 ft., % in. mesh; 2 common 

 sense minnow seines, 4X10 ft. and 4X25 ft.; 2 gill nets, 4X75 

 ft., % in. mesh; 2 gill nets, 4X75 ft., 1 in. mesh; 2 gill nets, 

 4X75 ft., V/z in. mesh; 2 gill nets, 4X75 ft., 2 in. mesh; 2 gill 

 nets, 4X75 ft., 3 in. mesh. Besides these nets a square dip 

 net 4X4 ft., a cast net, a trammel net, and equipment for trot 

 lines were taken along, but never used. There were no fishes 

 large enough for the trammel net. The cast net purchased in 

 the United States was found to be much inferior to those in use 

 by the Venezuelans; the latter were of great value, especially 

 in the swift streams.
