REPORT OF THE SECBETAEY 33 



Dr. Ales Hrdlieka, curator of physical anthropology, left in May 

 on a fourth expedition to Alaska, for the purpose of obtaining 

 measurements and, if possible, casts of the few remaining full-blood 

 Aleutians. He expected to work in the region of supposed contact 

 between the Eskimo, the Aleut, and the Indian, and to examine the 

 various mountain passes between Bering Sea and Cook Inlet and 

 the Gulf of Alaska, through which migrations of early man from 

 the Bering Sea area southward may have been possible. 



Dr. Paul Bartsch, through the Walter Rathbone Bacon Traveling 

 Scholarship under the Smithsonian Institution, continued field work 

 in the Vv^est Indian islands in a study of the terrestrial molluscan 

 fauna of this area, completing a program of travel initiated two 

 years ago. This year efforts were focused on the southern Bahamas, 

 the islands off the south coast of Cuba, and the Cayman group. Doc- 

 tor Bartsch was accompanied by three assistants, Harold Ciuttick, a 

 student of George Washington University ; Ray Greenfield, who had 

 been with him two years ago in Cuba ; and Alva G, Nye, jr., of Wash- 

 ington. Harold Peters of the Bureau of Entomology, also accom- 

 panied the party to collect specimens of avian parasites. The party 

 left Miami, Fla., on June 9, 1930, in the Island Horae^ a 33-ton, shal- 

 low-draft vessel. Work was carried through the islands and cays of 

 the southern Bahamas until August 6, and then the party explored 

 the wonderful molluscan fauna of Great Inagua Island, which 

 proved by far the richest of all the Bahamas. On reaching Guanta- 

 namo, Cuba, the Island Horiie was pronounced unseaworthy, and an- 

 other boat the Jose Enrigue^ a 35-ton sloop with an auxiliary 22 

 horsepower gasoline engine, was chartered at Santiago. On August 

 28 the party continued through the keys along the south coast of 

 Cuba, and from September 10 to September 17 was occupied on Cay- 

 man Brae, Little Cayman, and Great Cayman islands. Sails were 

 then set for Cuba, and until September 24 the keys along the coast 

 from Cayo Largo to the Isle of Pines were searched. On Septem- 

 ber 29 the port of Batabano, Cuba, was reached and the collections 

 were shipped by rail to Habana. The expedition returned to Wash- 

 ington on October 3. This cruise yielded a larger amount of mollus- 

 can material than any of the previous trips, no less than 250,000 

 specimens of mollusks being secured, together with many observa- 

 tions on molluscan faunistic relations. Large collections in other 

 groups were also obtained, among them 925 bird skins and 596 rep- 

 tiles and amphibians, besides a number of live animals, principally 

 reptiles, for the National Zoological Park. 



The Rev. David C. Graham, whose explorations in western 

 Szechwan, China, and the neighboring regions of Tibet, have 

 been a feature of these reports for many years, continued work near
