6 ANNUAL REPORT OF THE 
vician fossils in several museums in England, France, Germany, 
Russia, Sweden, and Norway. 
The Museum is indebted to Messrs. Bangs, Barbour, Bigelow, 
Brewster, Faxon, and Sayles for the care they have taken of the 
collections under their charge. Their reports and those of the 
other Curators give the usual details of the work accomplished : 
and of the more important accessions received during the year. 
The Museum is likewise indebted to Dr. L. E. Griffin for assist- 
ance in the determination and arrangement of its large series of 
stony corals, and also to Miss E. B. Bryant, who, by her own 
efforts and through exchanges, has added much material to the 
collection of Araneina. Miss Bryant has, as in recent years, 
given her time freely to the care and identification of this collection 
which is in a most satisfactory condition. 
Dr. G. M. Allen has identified, catalogued, and labeled the 
mammalian accessions received during the year, has effected some 
important exchanges, and attended to the loan of material to 
specialists. He has completed the rearrangement of the fossil 
Primates, Cetacea, Edentata, and Marsupialia, and has incor- 
porated these with the skeletal remains of recent forms; a similar 
rearrangement of the Ungulata has been begun. Dr. Allen has 
also reviewed the entire collection of recent Primates and has 
sorted over the alcoholic Rodentia, Carnivora, and Insectivora. 
Mr. W. F. Clapp has continued his work upon the Mollusca 
during the whole year; he has revised the entire series of Cephalo- 
poda, Pteropoda, and Heteropoda and made considerable progress 
with many genera of Gasteropoda, while the work on recent 
accessions has been kept well in hand. Mr. Clapp has also 
studied the Salpae, Heteropoda, and Pteropoda collected by the 
GRAMPUS. 
Miss Elvira Wood worked for eight months upon the fossil 
crinoids, and the research series is now in excellent condition for 
study. She has also reviewed the fossil crinoids on exhibition in 
the Systematic Room. 
Mr. J. D. Sornborger has worked throughout the year upon the 
rough mammalian skeletons and has made many ligamentous 
skeletons of birds from fresh material received from the Boston~ 
Park Commissioners. = 
The work of a Museum Preparator is subject to so many inter- 
ruptions and changes that progress toward any special end is 
oftentimes disappointingly slow. The more notable results of 
Mr. George Nelson’s ‘work for the exhibition collections consist —
