ceived; the edition for the 140 plates was completed some years 

 ago. 



The Library contains 59,846 volumes and 65,253 pamphlets; 

 1,207 volumes and 3,108 pamphlets have been received during the 

 year. 



The publications for the year include one number of the Memoirs, 

 six numbers of the Bulletin, and the Annual Report, a total of 417 

 (64 quarto and 353 octavo) pages illustrated by 41 (26 quarto, and 

 15 octavo) plates. The Memoir gives a detailed systematic ac- 

 count of the genus Sphaerodactylus ; one number of the Bulletin 

 contains a report on the exploration of the coastal water off the 

 northeastern United States in 1916 by the Grampus, and five 

 numbers of the Bulletin are based on Museum collections. 



The Museum is indebted to Dr. Thomas Barbour for the plates 

 illustrating his Memoir on Sphaerodactylus, and also for extra 

 service in the preparation of a very considerable amount of mam- 

 malian osteological material. 



For voluntary work upon the collections of spiders and birds the 

 Museum is indebted to Miss E. B. Bryant and Mr. T. E. Penard.
