10 ANNUAL REPORT OF THE 



REPORT ON THE REPTILES AND AMPHIBIANS. 



By Thomas Barbour. 



This year has been most satisfactory with respect to material 

 received. Dr. E. R. Dunn has rearranged the whole series of 

 alcoholic Chelonia, and finds that we have over forty of the fifty- 

 seven genera recognized by Siebenrock. 



In company with Mr. Winthrop S. Brooks, I spent several 

 months during the spring of 1922 collecting in eastern Panama. 

 We visited Cuba and Costa Rica as well. Mr. J. L. Peters visited 

 the West- Indies (Saint Eustatius, Nevis, Anguilla, and Saint 

 Christopher) with good results. Since my previous report the 

 collection of Rana has been revised, and we now have represented 

 123 species out of about 166 worthy of recognition. Mr. F. R. 

 Wulsin's extensive travels in China have supplied many choice 

 reptiles, the alligators being especially noteworthy. 



By gift and purchase we have acquired two splendid additions 

 to our African material, from Mr. Arthur Loveridge, of Tanganyika 

 Territory, and from Mr. George Schwab of the Cameroons. Rich 

 series from Argentina and Chile have come in as part of the results 

 of the Phillips Expedition, Mr. J. L. Peters, collector, and an 

 arrangement made with Don Carlos Reed has resulted in several 

 fruitful journeys in the Cordilleran region. Several collections 

 from Mexico, made by Mr. W. W. Brown, have been purchased; 

 also collections from Southern China, made by Rev. John Graham, 

 and from Siam, by Dr. Malcolm Smith, from Pontevedra and Val- 

 encia, Spain, by Mr. F. Z. Cervera; and arrangements have been 

 made, of mutual advantage, with the Rev. Brothers Apolinar 

 Maria, Niceforo Maria and other clerics in South America. 



Welcome gifts have been received from Dr. A. W. Sellards, 

 Dr. H. W. Smith, Mr. Eugene Lieder, Mr. F. P. Dillon, Prof. M. 

 L. Fernald, Prof. H. H. Wilder, Dr. E. R. Dunn, and Col. J.
