been articulated and mounted in the centres of the geological and 
mineralogical halls and attract much attention. This work was 
done by the Academy’s taxidermist, Mr. David McCadden, assisted 
by Mr. E. W. Stucke. 
The collection of skins of the larger mammals was carefully gone 
over during the year and systematically arranged by Dr. Witmer 
Stone, while the entire osteological collection was systematized and 
labelled by Mr. Earl L. Poole, a student on the Jessup Fund. This 
collection is now readily accessible and its usefulness vastly increased. 
Twenty-six mammals have been received from the Zoological 
Society of Philadelphia during the year, which have been variously 
prepared by the taxidermist as skins or osteological material. 
A set of the McGregor restorations of Pithecanthropus and other 
early anthropoid and human types was presented by Dr. Samuel G. 
Dixon. 
Numerous students have made use of the collections during the 
year and specimens have been loaned to Drs. J. A. Allen and C. Hart 
Merriam, Messrs. W. H. Osgood and H. W. Henshaw. 
Birds. 
The rearrangement and renovation of the study series of birds 
have progressed satisfactorily during the year and only five families 
of the Passeres and the Steganopodes still demand attention. Mr. 
D. E. Culver, student on the Jessup Fund, has relaxed the old 
unmounted specimens and remade many of the skins, while Dr. 
Witmer Stone has systematically arranged and labelled the groups 
as they were completed. He has also entirely rearranged the local 
study series of land birds, bringing all of the local material together 
for the first time. 
A number of specimens have been identified for the Zoological 
Society and for correspondents. 
■ Mr. Samuel N. Rhoads, accompanied by Mr. Earl L. Poole, 
undertook an expedition to Guatemala, from February to April, in 
the interests of the Academy, the expenses being met partly by the 
Academy and partly by Mrs. Beulah M. Rhoads and William P. 
Elkinton. 
A fine series of about 700 birds, a number of mammals ^nd some 
specimens in other branches were obtained. 
Besides this material an additional series of birds from Santa Marta, 
Colombia, was purchased, as well as a series of Petrels from South 
Georgia Island.
