REPORT OF THE SECRETARY 25 



and in addition much new material was secured for the Museum by 

 exchange arrangements. 



Dr. G. A. Cooper, assistant curator of stratigraphic paleontology, 

 collected during his vacation, at his own expense, in classical De- 

 vonian localities in New York State. At the close of his work he 

 presented to the Museum more than 2,500 specimens. 



The field explorations of C. W. Gilmore, curator of vertebrate 

 paleontology, covering the Miocene and Oligocene formations of 

 southwestern Montana, and the Wasatch of the Bighorn Basin, Wyo., 

 met with gratifying success. The material collected will fill long- 

 existing gaps in the collections, and it is anticipated that study will 

 reveal many undescribed forms. 



Excavations were continued in the fossil-horse quarry near Hager- 

 man, Idaho, under the direction of Norman H. Boss, chief preparator 

 in the division of vertebrate paleontology, resulting in the recovery 

 of 4 more or less complete articulated skeletons, 32 skulls, 48 jaws, 

 and a vast assemblage of skeletal parts. 



The Walter Rathbone Bacon traveling scholarship under the 

 Smithsonian Institution has been awarded for the current period to 

 Alan Mozley for study of the land and fresh-water molluscan fauna 

 of Siberia. Mr. Mozley left for the field in the spring of 1932 and 

 proceeded to Tomsk, Siberia, where he intends to establish head- 

 quarters for this year's exploration. Mr. Mozley reports that he will 

 make an expedition to the mouth of the River Ket, and later, after 

 returning to Tomsk, will make an excursion south into the Akhmo- 

 linsk Steppe. He reports cordial cooperation of the local authorities 

 and scientific institutions. 



Dr. J. M. Aldrich, curator of insects, collected Diptera in the Gaspe 

 Peninsula of eastern Quebec. He obtained a large collection of flies, 

 establishing the fact that a large number of southern species have a 

 much wider distribution northwards than has hitherto been sup- 

 posed, though the lower St. Lawrence River appears to form a suffi- 

 cient barrier against the spread of the northern flies southward, as 

 no strilring forms of the Labrador fauna w^ere found. 



Dr. Paul Bartsch, curator of mollusks, with financial assistance 

 from the Carnegie Institution of Washington, again visited the 

 Florida Keys to examine the Cerion colonies planted during previ- 

 ous years to determine the effect on these mollusks of changes in 

 environment, as well as of hybridization, a work in which the Smith- 

 sonian Institution and the Carnegie Institution have cooperated 

 since 1912. 



Gerrit S. Miller, jr., curator of mammals, traveling at his own ex- 

 pense, with some assistance from the Smithsonian for the hire of 

 labor, visited Puerto Rico during March and April with the main
