TWENTIETH ANNUAL REPORT 79 



Two other papers for Zoologica, relating to ecological field 

 work near Para, were written, and will be published early in 

 1916. 



Papers published during the year, relating to work in the 

 Department of Birds were as follows : 



"Spiders Collected by C. William Beebe in Burma and Bor- 

 neo," including Ten New Species (Petrunkovitch, Ann. Entom. 

 Soc. Am. VII, p. 169). 



*'Two New Genera of Myrmicine Ants from Brazil," Ble- 

 pharidatta brasiliensis and Glamijronujnnex beebei. (Wheeler, 

 Bull. Mus. Comp. Zool. Harv., LIX, p. 483.) 



"Relationship of the Tupaiidae and the Eocene Lemurs, 

 Especially Notharctus." (Gregory, Bull. Geol. Soc. Amer. Vol. 

 24, pp. 247-252.) 



By far the most vital undertaking inaugurated by this De- 

 partment is the planning of a Tropical Zoological Station in 

 Georgetown, British Guiana. This is described elsewhere. In 

 brief, its purpose will be research in the life histories of various 

 groups of vertebrates and invertebrates, with special reference 

 to the more general problems of evolution. Curator Beebe will 

 be in charge, with Mr. Inness Hartley as Research Associate 

 and Mr. Paul Hjwes as Research Assistant. The second object 

 of the work will be the collecting and shipping to the Zoological 

 Park of interesting rare types of living vertebrates. Mr. Donald 

 Carter will be attached to the Station as collector. The party 

 will reach British Guiana about February 1, and will remain 

 in the field at least one year.
