16 THE AMERICAN CHARACIDAE. 



Central American Expeditions. 



From time to time specimens have been secured by exchange with the Field 

 Museum of Chicago. These had been collected by the late Dr. S. E. Meek in 

 various parts of Mexico and Central America. Accounts of this material have 

 appeared in various publications of the Field Museum. 



In collaboration with Mr. S. F. Hildebrand, Dr. Meek was engaged at the 

 time of his death on a report of the fishes of Panama. Mr. Hildebrand has com- 

 pleted the report in the Laboratory of Indiana University and has given me the 

 opportunity to examine many of the specimens collected in Panama. Dr. 

 Meek as the representative of the Field Museum, and Mr. Hildebrand, Director 

 of the Beaufort Laboratory of the Bureau of Fisheries, as the representative of 

 the Smithsonian Institution, spent two seasons in Panama to collect fishes. 

 A report on their itinerary and on their collections has been published by the 

 Field Museum (Field museum publication 191, zool. ser., 10, 1916, p. 217-374, 

 pi. 6-32). They collected in various localities of the east-slope Chagres Basin, 

 many of which are now covered by Gatun Lake, and in others of the Pacific 

 slope Grande basin of the Canal Zone. In addition they collected in the basins 

 of the Rio Chepo, and Tuyra of the Pacific slope, south of the Canal Zone, and 

 in a few of the smaller rivers both north and south of the Canal Zone on both 

 the east and west slopes. 



The Expedition to Guatemala. 



During January, February, and March of 1915, Mr. Newton Miller assisted 

 by Messrs. E. B. Williamson, C. C. Deam, and Prof. J. Hines collected fishes at 

 Tenedores, Los Amates, Algeria, Gualan, Zacapa, and El Rancho in the Motagua 

 Basin of Guatemala. Additional collections were secured at Puerto Barrios 

 and Santa Lucia. The first series of specimen is in Indiana University.
