30 ANNUAL REPORT OF THE 



REPORT ON THE REPTILES AND AMPHIBIANS. 



By Thomas Barbour. 



The collections have increased very considerably during the year. 

 Advantageous exchanges with the American Museum of Natural 

 History, the Leyden Museum, the Natural History Museum of 

 Basel, the U. S. National Museum, the British Museum of Natural 

 History, and with Mr. Julius Hurter, Sr., have added many 

 genera and species which were previously unrepresented. Ac- 

 knowledgements are due to Prof. W. M. Wheeler for Amphibia 

 from Central America; Mr. C. T. Brues, Amphibia Salientia from 

 Jamaica; Dr. H. L. Clark, reptiles from Montego Bay; Mr. 

 George Nelson, reptiles from Swan Island in the Caribbean Sea; 

 Prof. H. W. Smith, many interesting reptiles and amphibians 

 from Sarawak, Borneo; Mr. J. L. Peters, reptiles and amphibians 

 from the Rio Hondo district in British Honduras and Quintana 

 Roo, Mexico; and to Rev. George Schwab, for many valuable 

 reptiles and amphibians from western Africa. Some interesting 

 reptiles have been received from the New York Zoological Society 

 through Mr. R. L. Ditmars. Mr. William Brewster, and Prof. E. 

 L. Mark have also made gifts to the collection. Much unidentified 

 material was sent to Dr. A. G. Ruthven for study and a part has 

 been returned carefully identified. Many rare forms previously 

 unrepresented in the collection have been obtained by purchase. 



From the middle of January to the middle of March, I collected 

 in western and central Cuba, and was unusually fortunate in 

 securing new and little known species. Mr. R. M. Grey, Dr. C. 

 de la Torre, Messrs. Jesus Valdivia, and Victor Rodiguez all con- 

 tributed specimens of rare Cuban reptiles, and for these thanks 

 are due.
