MUSEUM OF COMPARATIVE ZOOLOGY. / 



flesh and the call for his services in the preparation or development 

 of material, new and old, to aid the studies of the several Curators 

 or of investigators elsewhere, not infrequently delays the comple- 

 tion of specimens for exhibition. Two of the more noteworthy 

 prepared this year are a Manatee obtained in 1919 at Sebastian, 

 Fla. by Mr. Nelson himself, and an especially fine Sail-fish, Istio- 

 phorus nigricans (Lacepede) taken off Long Key, Fla. by Mr. 

 George R. Agassiz. 



After Mr. Nelson's masterly remount of the Audubon Great Auk, 

 mentioned in last year's Report, Dr. Sanford's wish that the 

 " Nay lor " Great Auk and two Labrador Ducks should be entrusted 

 for remounting to the same competent hands was but natural, and 

 in placing Mr. Nelson's time and skill at his disposal, the Museum 

 had a genuine satisfaction, due to the exceptional scientific value of 

 the birds, and to Dr. Sanford's liberality in allowing the Museum to 

 share in the results of his well-directed and successful work for the 

 promotion of ornithological exploration. 



For the voluntary work of Miss Elizabeth B. Bryant and Mr. T. 

 E. Penard the Museum is greatly indebted. 



The Library contains 58,639 volumes, and 62,145 pamphlets; 

 1,225 volumes and 2,159 pamphlets have been received during the 

 year. 



The publications for the year include two numbers of the 

 Memoirs, five numbers of the Bulletin, and the Annual Report, a 

 total of 438 (144 quarto, and 294 octavo) pages, illustrated by 41 

 (32 quarto, and 9 octavo) plates. One number of the Memoirs 

 contains the Report on the Holothurians collected during the 

 expeditions of the U. S. Fisheries Steamer Albatross in the 

 Tropical and Eastern Tropical Pacific, during the years 1899-1900 

 and 1904-1905. This Memoir completes the reports on the 

 Albatross echinoderms. The other Memoir contains the third 

 part of Dr. C. H. Eigenmann's account of the American Characidae. 

 All five Bulletins are based upon Museum collections. 



The Museum suffered a severe loss in the death of Walter Faxon, 

 which occurred at Lexington, 10 August, 1920. Associated with 

 the work of the Museum for nearly fifty years, Dr. Faxon's cura- 

 torial charge of the Crustacea and Mollusca gives an all too in- 

 adequate indication of his services and of the breadth and extent
