176 PROCEEDINGS OF THE NATIONAL MUSEUM vol.94 



In order to obtain fishes from the headwaters of the rivers at the 

 southern end of Lago Maracaibo, a trip into the high Andes was made 

 from March 27 to April 4. The Rio Chama, Rio Catatumbo, and 

 Orinoco systems yielded many specimens. 



From April 7 to 23 collections were made in Lago Maracaibo in the 

 vicinity of Lagunillas and Pueblo Viejo, eastern side of the lake. 



Between April 29 and May 5 collections were made in the lake and 

 in rivers at the southern end of Lago Maracaibo. Chesley Pickle 

 kindly took me and my equipment in the Indiana so that I could stay 

 on the boat Emma as guest of John Taylor. 



A second trip was made to Caracas on May 9 by airplane, and while 

 there I was the guest of Mr. and Mrs. William H. Phelps, who enter- 

 tained me graciously and to whom I extend my sincere thanks and 

 appreciation for an enjoyable stay in Caracas. 



Upon returning again to Maracaibo on May 14, 1 secured specimens 

 of fishes from the Maracaibo market until the 21st, when it was 

 necessary to send my specimens and equipment to the dock for 

 shipment back to the United States. 



I returned by plane to Miami, Fla., on May 24, and arrived in 

 Washington, D. C, on May 26, 1942.

 Maracaibo, near an oilfield called Totuma. The river here was 100 to 300 feet 

 wide and made up of a succession of rapids and ponds, vdth muddy to sandy 

 bottoms in the quiet pools and rubble to sand in the rapids.
