22 ANNUAL REPORT OF THE 



REPORT ON THE REPTILES AND AMPHIBIANS. 



By Thomas Barbour. 



The year has been an unusually fortunate one as more than the 

 customary amount of interesting material has been received. 



Dr. G. M. Allen spent August and September, 1919, in Haiti, 

 visiting also Gonaive Island where several new species were 

 secured, and since that time, thanks to his diligence, most of the 

 new material has been entered on the register and card catalogue 

 and intercalated in the collection. 



Mr. E. R. Dunn collected during the summer of 1919 in the 

 high mountains of the Southern States and secured very many 

 beautifully preserved urodeles, as well as other amphibians and

 received indicate that he is reaping a rich harvest both in the 

 tropical lowlands and in the higher altitude. 



From December to the end of April, I was in Florida and Cuba, 

 where, with the welcome help from Mr. W. S. Brooks, many 

 desirable mammals, reptiles, amphibians, and fishes were obtained. 



The series of Ranae was revised by Mr. Dunn, and the new cards 

 show that the collection has ninety-eight of the 165 species re- 

 cently recognized by Boulenger. The collection of Urodeles con- 

 tains thirty-five genera and 119 species. 



Dr. Mook of the American Museum of Natural History studied 

 the skeletal material of the crocodilians and has borrowed seven 

 skulls and six skeletons. Mr. G. K. Noble of the same Museum 

 has also studied our Peruvian material and 420 specimens have 

 been loaned him for study. 



Gifts have been received from the United Fruit Company, Dr. 

 Malcolm Smith, Mr. C. A. Mosier, Mr. Arthur Loveridge, and 

 Mr. E. R. Dunn. 



Excellent material has been obtained by exchange from the
