2 Annals of the Carnegie Museum. 



began his exploration of the avifauna of the same country, resulting 

 in the ultimate publication in 1907 of his fine paper upon the Birds of 

 Costa Rica. Mr. Carriker soon after the appearance of his work upon 

 the avifauna of Costa Rica repaired to Santa Marta, where he has 

 since made his home, while continually collecting for the Carnegie 

 Museum. 



It is not necessary in this connection to do more than make allusion 

 to the extensive journeys and collections made at later dates by John 

 D. Haseman, S. M. Klages, Jose Steinbach, and numerous other 

 " naturalistes voyageurs," who have been in our employment; nor to 

 the piscatorial labors of Dr. C. H. Eigenmann and his associates, who 

 have made extensive contributions to our knowledige of the freshwater 

 fishes of South America. 



The present volume of the Annals reflects in part the results of the 

 efforts of the Carnegie Museum to give to the world a knowledge of 

 one phase of the natural history of an interesting South American re- 

 gion, one of many which have been and are being systematically ex- 

 plored in the interests of science by the Museum, which bears the name 

 of that great lover of his kind, Andrew Carnegie. 



Mr. W. E. C. Todd is the senior author and Mr. M. A. Carriker, Jr., 

 the junior author of the publication, the former having devoted him- 

 self to the study of the material from a taxonomic standpoint; the 

 latter having supplied numerous notes in regard to the localities where 

 the collections were made and to the habits of the species. Mr. George 

 Miksch Sutton deserves great praise for the drawings of species hith- 

 erto unfigured, which have been reproduced upon Plates II to VII.
