The United States Fish and Wildlife Service, through various mem- 

 bers of its staff, has continued to assist us in maintaining an interesting 

 collection during the year. A pair of MacQueen's bustards {Chlam.y- 

 dotis undulata macqueenii) was presented through Gardner Bump and 

 the State of New Mexico. The first Ross's snow geese {Chen rossi) 

 received since 1915 were sent by Vernon Ekedahl, superintendent of 

 the Sacramento National Wildlife Refuge, from Willows, Calif. He 

 also sent other North American waterfowl, which are enumerated in 

 the list of donors. Other members of the Fish and Wildlife Service 

 who assisted are given in the list of donors. 



W. W. Dornin, of Phoenix, Ariz., continued from time to time 

 to send choice specimens of reptiles of the southwestern United States. 



Valuable specimens were received during the year from J. D. Hand- 

 man, Nyasaland Railways Ltd., Monkey Bay, Nyasaland, Africa. As 

 this is a region little known zoologically, all the specimens are unusual 

 in collections. Outstanding among these was a file snake {Simoce- 

 phalus capensis) . 



The United States Army Medical Unit in Malaya, under the leader- 

 ship of Lt. Col. Robert Traub, again brought to the United States 

 particularly interesting animals that were made available to the Na- 

 tional Zoological Park after they had served their purpose with the 

 Medical Unit. Although the collection was not large, all the specimens 

 were very desirable. They included 2 baby orangutans {Pongo 

 pygmaeus abelii) ; 2 young small-toothed civets {Arctogalidia trivir- 

 gata) ; 4 ferret-badgers {Helictis everetti) ; 2 tree shrews {Tupai 

 montana baluensis) ; 4 choice specimens of the big black rat of Mount 

 Kinabalu, North Borneo {Rattus infraluteus) ; 1 Bornean porcupine 

 {Trichys lipura) ; and 1 remarkable tiny spineless hedgehog {Hylo- 

 mys suillus dorsalis). On the long trip from Asia the animals were 

 cared for by Charles Wharton, a zoologist who had been with the 

 Medical Unit. 



The Johns Hopkins Research Center deposited in the Zoo a group 

 of young chimpanzees that have proved to be a fascinating exhibit.
