REPTILES AND AMPHIBIANS 



The additions to the catalogued study collections for 1917 

 total 2,651 specimens — 372 batrachians and 2,279 reptiles, not 

 counting the Nicaragua collection (about 2,500 

 Accessions and specimens). Notable among these additions are 

 133 specimens from the work of the Museum's 

 Asiatic Zoological Expedition in high altitudes in Yunnan, 

 China; 66 from John Graham, Yunnan; 36 from Manchuria, 

 gift of Makoto Nishimura; 67 from high altitudes in North 

 Carolina, gift of Morton L. Church ; and many smaller collec- 

 tions from South America and the American Southwest. 



Outstanding exchanges have been completed by shipments of 

 material to the Institut de Butantan, Sao Paulo, Brazil, and the 

 California Academy of Sciences, San Francisco. Notable re- 

 ceipts closing exchanges include 52 specimens from the 

 Albany Museum, Grahamstown, South Africa; 10 from the 

 Museum of Comparative Zoology, Cambridge ; and several hun- 

 dred specimens of Costa Rican and Colombian species, includ- 

 ing 24 types described by Cope, from the Commercial Museum, 

 Philadelphia. At the close of the year an exchange was ar- 

 ranged with the British Museum, and several shipments of 

 North American frogs will be sent within the next few weeks 

 for use by Dr. Boulenger in his revision of the genus Rana. 



By temporary exchange or loan of material for mutual ad- 

 vantage in special work during 191 7, the department has co- 

 operated with the following American institutions : the United 

 States National Museum, Washington; the Museum of Zool- 

 ogy, University of Michigan; the Museum of Comparative 

 Zoology, Cambridge; and the Field Museum of Natural His- 

 tory, Chicago. In addition, courtesies have been received in 

 the shape of loaned collections for comparative study from the 

 Academy of Natural Sciences, Philadelphia, and from the 

 Brooklyn Museum. The most important of outgoing collec- 

 tions loaned by the American Museum consists of our material 

 from Peru, Bolivia, Ecuador and Chile, sent to Cambridge.
