4 ANNUAL REPORT OF THE 



personal charge during a part of this season's cruise. The work 

 included a general hydrographic survey of the Gulf of Maine, 

 Georges Bank, and the continental shelf south of Cape Sable, 

 with the usual trawl- and net-hauls, temperature and tidal data, 

 etc. 



Mr. E. R. Dunn spent the summer of 1919 in the mountains of 

 Virginia, North Carolina, Alabama, and Tennessee, and secured 

 a large series of reptiles and amphibians. Mr. Dunn's work in 

 Costa Rica during July, 1920, will be noticed in the Report for 

 1920-1921. 



Mr. W. S. Brooks worked with Dr. Thomas Barbour during the 

 winter and early spring, collecting in Cuba and among the Florida 

 Keys; they secured many desirable mammals, birds, reptiles, 

 amphibians, and fishes. Mr. Brooks also spent several weeks on 

 Anticosti where he collected a few mammals and birds and a small 

 series of shells and insects. Prof. Theodore Lyman kindly aided 

 Mr. Brooks's work in Anticosti. 



Dr. G. M. Allen visited Haiti during August and early Septem- 

 ber, 1919, and though unsuccessful in his search among the cave- 

 deposits, the main object of his trip, he collected a few bats, and a 

 number of reptiles, three of the latter proving new species. The 

 field-w r ork of Dr. Allen and Messrs. Dunn and Brooks was due to 

 the generous assistance of Dr. Thomas Barbour, who also provided 

 for some additional work upon the collections. 



The ornithological and conchological departments have benefited 

 by the voluntary work of Messrs. T. E. Penard and E. G. Hum- 

 phrey, to whom the thanks of the Museum are due. The excel- 

 lent condition of the large collection of Araneae is ow T ing to the 

 interest and care bestowed upon it by Miss E. B. Bryant. 



The William Brewster bequest constitutes not only the most 

 important accession received during the year, but one of the chief 

 scientific acquisitions received since the foundation of the Museum 

 in 1859. 



The terms of the bequest are printed as Appendix A {infra, 

 p. 42). 



The bequest includes : — 1 . Collection of mounted birds and 

 bird skins. 2. Collection of nests and eggs. 3. Collecting 

 apparatus. 4. Books, pamphlets, prints, and Audubon portrait.
