96 REPORT OF NATIONAL MUSEUM, 1919. 



The only new expedition sent out during the year we owe to Doctor 

 Abbott's continued interest in the Museum. On the retirement of 

 Mr. Raven, he generously arranged to send Mr. Charles M. Hoy to 

 Australia for the benefit of the Museum. Mr. Hoy sailed early in 

 May and has reported his safe arrival in Sydney. The object of his 

 work will be mainly to procure series of the birds and mammals 

 which are in danger of extermination. Many of these are not now 

 properly represented in our collections. Hence this expedition prom- 

 ises to be of very unusual importance. The first collecting field will 

 probably be in the vicinity of Cape York. 



Distribution and exchange of specimens. — Duplicates distributed 

 to schools, colleges, institutions, and individuals aggregated 3,917 

 specimens, of which 1,044 were in 6 sets of 174 mollusks, each regu- 

 larly prepared for this purpose. One hundred and five bird skins 

 from Polynesia, part of the collections made during the Albatross 

 Pacific Expedition, 1899-1900, under the direction of Dr. Alexander 

 Agassiz, were sent to the Museum of Comparative Zoology, Cam- 

 bridge, Massachusetts. To the British Museum a collection of 390 

 named Lepidoptera was presented as well as a few isopods, and to the 

 Bruce Museum, Greenwich, Connecticut, 1,982 specimens, mollusks, 

 reptiles, and fishes. The remaining specimens were sent to various 

 institutions and specialists. 



Exchanges to the number of 4,352 specimens were arranged, 3,836 

 of which were botanical. Of the 516 zoological specimens, 57 hum- 

 ming birds and 100 mollusks were sent to Mr. E. Ashby, Blackwood, 

 South Australia; 244 mollusks to Dr. F. Felippone, Montevideo, 

 Uruguay; while the remainder were disposed of by exchange with 

 various institutions and individuals. The largest exchanges of plants 

 were sent to the Oregon AgTicultural College ; British Museum ; Cali- 

 fornia Academy of Sciences; Gray Herbarium, Cambridge, Massa- 

 chusetts ; Missouri Botanical Garden ; New York Botanical Garden ; 

 Field Museum of Natural History; College de Longiieuil, Quebec, 

 Canada ; and the Botanic Gardens, Sydney, Australia. The remain- 

 ing exchanges were mostly with individual botanists.
