mingo and Navassa" (introducing a new tree frog and a new 

 lizard from Santo Domingo and 5 new lizards from Navassa 

 Island), by K. P. Schmidt; in Copeia, "Rediscovery of Am- 

 phiardis inornatus Garman," by K. P. Schmidt. A paper on 

 "Some New Batrachians from Colombia," by G. K. Noble, is 

 ready for press; Mr. Noble is also joint author with Thomas 

 Barbour of a paper, published in the Bulletin of the Museum 

 of Comparative Zoology, on "Amphibians from Northwestern 

 Peru." 



Courtesies received from other institutions in the shape 

 of temporary loan or opportunity for examination of material 

 in connection with research are as follows: Collections of 

 African amphibians and African snakes, Museum of Compara- 

 tive Zoology at Harvard College; and collections of African 

 amphibians, Museum of the University of Michigan. A con- 

 siderable collection of unidentified snakes from Kamerun, 

 Africa, has been loaned by the Museum of Comparative Zo- 

 ology for identification. 



The exhibition work has continued as in former years in 

 preparation of casts from life for the synoptic series, of speci- 

 mens as obtained for an exhibit covering the 

 Exhibition poisonous snakes of North America, and of the 

 animals and plant forms for the two large habi- 

 tat groups in hand, namely, the Florida Gopher Turtle and the 

 New Zealand Hatteria. The artists and preparators experi- 

 enced in making these herpetology exhibits have had the pleas- 

 urable opportunity on several occasions during the year to 

 demonstrate the methods of the work to guests from museums 

 in other parts of the world. 



Work in the field has been necessarily limited in amount. 

 Some local collecting by the members of the department has 

 been done, especially on the New Jersey pine 

 barrens. The two months' survey of Porto Rico 

 and the neighboring islands by Mr. Schmidt resulted, in addi- 

 tion to the large representative collection, in the accumulation 

 of a large body of facts regarding habits and life histories and 

 the addition of a species of snake and 6 species of tree frogs,
