NATURAL SCIENCES OF PHILADELPHIA.

A number of mammals received from the Zoological Society of Phila- 
delphia have been mounted or prepared as study specimens in the 
Taxidermical department, notable among the former being a bull 
American Bison, a Wild Boar and a Bubaline Antelope. 
Besides the services rendered by the Museum staff and the students 
of the Jessup Fund, the Curators are indebted to Dr. P. P. Calvert, 
Messrs. Erich Daecke, H. W. Wenzel, H. L. Viereck and E. T. Cresson, 
Jr., for aid in the Entomological department, and Mr. S. S. Van Pelt in 
the Herbarium. 
The Anti-Tuberculosis Society, Philadelphia Botanical Club, Dela- 
ware Valley Ornithological Club and the Entomological Club of the 
American Association for the Advancement of Science have held 
meetings at the Academy during the year. At the time of the meeting 
of the latter body in Philadelphia a general meeting of entomologists 
was held at the Academy with a view to forming a national organiza- 
tion, and a reception was given by the Botanical Section to the visiting 
botanists. 
The collections have been constantly studied by visiting specialists, 
and during the year material has been loaned to Walter K. Fisher, E. 
L. Morris, Miss H. Richardson, Carlton R. Ball, Paul Bartch, C. V. 
Piper, E. W. Nelson, F. C. Paulmier, W. H. Osgood, E. B. Williamson, 
H. F. Osborn, R. L. Ditmars, H. L. Clark, F. C. Baker, H. C. Ober- 
holser, G. S. Miller and A. Ortmann.

Report of the Special Curator of the Department of Mollusca. 
The collections of mollusca remain in good order, through from the 
crowded condition of the department the specimens of some groups are 
not as accessible as we would desire. The installation of a series of 
storage cases has given room for a rearrangement of the fresh-water 
mussels, which have been reclassified in accordance with Mr. Simpson’s 
recent synopis of the group, and now occupy about 850 square feet of 
space. Several extensive families of small land snails have been 
removed from the exhibition series and rearranged in storage cases, 
leaving merely a few typical species to represent them in the public 
exhibit. The series of American land snails, rearranged and expanded, 
is in storage cases, occupying about 600 square feet. The rapid growth 
of the collection has continued. Mr. Y. Flirase, of Kyoto, has con- 
tinued his sendings of Japanese mollusca, comprising many new forms.
