O ANNUAL REPORT OF THE 



tion; from Mr. E. B. Williamson, a series of Odonata; from Mr. 

 G. E. Cabot, fossil shells from California; from the Bermuda 

 Biological Station, Dr. E. L. Mark, Director, a large number of 

 marine invertebrates; from the U. S. National Museum, collections 

 of Cynipidae and echinoderms; and from the Institut Oceano- 

 graphique (Monaco), a collection of echinoderms. 



A holographic copy, dated Nov. 12, 1860, of Longfellow's well- 

 known poem, "The fiftieth birthday of Agassiz," has, through the 

 kindness of Mrs. George R. Agassiz, been added to the Museum's 

 memorabilia. 



The reports of the Curators give-the details of the work accom- 

 plished, and of the conditions of the collections in their charge. 



In his work upon the collections of mammals, Dr. G. M. Allen has 

 recorded the accession of over 800 specimens, and has added some 

 3,700 entries, chiefly fossils, to the card catalogue. He has re- 

 arranged much of the osteological part of the collection, and 

 developed and identified considerable fossil material. The skeletal 

 parts of the Indian Elephant, "Molly," from the Franklin Park 

 Zoological Garden, the gift of the City of Boston, to which the 

 Museum is already under obligation for important additions to its 

 collections, were prepared by Dr. Allen and Mr. Nelson with the 

 efficient aid of the N. Ward Company. 



The accessions to the collections of recent mollusks upon which 

 Mr. W. F. Clapp has been engaged throughout the year, have been 

 many and important. Valuable collections, not already men- 

 tioned, include an extensive series of operculate land shells received 

 from the Boston Society of Natural History, and smaller series 

 from Guatemala and the Canal Zone, the gifts of Messrs. A. 

 Hinkley and James Zetek. These collections and the Hirase 

 shells, Dr. Barbour's gift, consist very largely of species new to the 

 Museum. In addition to his routine work upon the collection, 

 Mr. Clapp has completed a report upon the shells obtained by 

 Dr. W. M. Mann among the Solomon Islands. 



Dr. R. T. Jackson's services were engaged for a part of the year, 

 during which he reidentified and labeled a portion of the collection 

 of fossil Echini. 



The scope of Mr. George Nelson's work, as Preparator, varies 

 very little from year to year, but the receipt of new material in the
