machus mocino) ; fer-de-lance snakes {Bothrops lanceolatus) ; king 

 cobra {Naja hannah) ; Gaboon viper {Bltis gabonica) ; Australian 

 copperhead snake {Denisonia swperba) ; the little burrowing snake 

 {Typhlops) from Africa; and coconut crabs {Birgus latro), which 

 were a gift to us from the Governor of Guam. 



The xlrmy Medical Center, through its various workers, has con- 

 tinued to turn over to the Zoo interesting animals no longer needed 

 in their work. Through Maj. Eobert Traub, of the Kesearch and 

 Graduate School, there was received a very fine collection of rodents 

 from Kuala Lumpur, Malay Peninsula. There were six different 

 species of the genus Rattiis, which included a very small richly colored 

 rat, and a large somber-colored one, as well as other intermediate 

 forms. These rats are of particular interest as they are being studied in 

 connection with human diseases. Also received through Major Traub 

 were three species of the inconspicuously marked squirrels of the 

 Callosciunis gi'oup, the long-pointed-nose Malayan ground squirrel 

 {LaHscus)^ another of the queer little pencil-tailed tree mice {Ghiro- 

 podomys)^ and three excellent specimens of the slow loris {Nycticebus 

 coucang). 



E. M. Blocker, of the Fresno (Calif.) Zoo, presented two California 

 jack rabbits, which were particularly desirable additions as they have 

 rarely been available to the National Zoo. 



Dr. Gabriel Ospina Kestrepo, Director of the Institute Nacional de 

 Antropologia Social de Colombia, Bogota, Colombia, kindly presented 

 the Zoo with two pygmy marmosets. These are the smallest of the 

 marmosets and, being rare in collections, are especially desirable 

 additions. 



It has been possible to acquire many of these rarities for the Zoo 

 through the use of air transportation to bring animals quickly from 

 their native haunts, and by maintaining contacts with persons in 

 remote regions who are interested in collecting specimens. By a con- 

 tinuance of these methods it is hoped to bring to the American public 

 more interesting creatures that have not heretofore been available 

 for study alive.
