furnished with mahogany book cases, the gift of Mrs. Charles Schaeffer, 
who has likewise presented a lantern and screen. 
The grounds adjoining the Museum have been sown with grass and 
carefully tended during the year, greatly improving their appearance. 
In the Museum the installation of plate glass and mahogany cases 
has continued, 3,500 cubic feet of exhibition space having been pro- 
vided during the year for mammals, birds and invertebrates. An 
oak wall-case has been placed in the Arclueological department and 
the woodwork of most of the old cases has been refinished. Numerous 
storage cases for birds, mammals, insects, plants and mollusks have 
been purchased. 
Through the liberality of Mr. Clarence B. Moore, Messrs. Stewardson 
Brown and H. W. Fowler were sent on a six-weeks’ trip to the south- 
western Florida keys in search of specimens of Liguus to supplement 
a valuable series collected and presented by Mr. Moore from the 
eastern and western coasts and adjacent keys. Though unsuccessful 
in its immediate object, the expedition obtained valuable collections 
of fishes, plants, etc. Later Mr. Moore sent out a second expedition, 
securing a series of the desired mollusks. 
Dr. H. A. Pilsbry spent two months in Cuba investigating the mol- 
luscan fauna in the interests of the Academy, and Mr. J. A. G. Rehn 
was engaged for one month in collecting insects and birds in southern 
Georgia. 
Mr. Clarence B. Moore has added a number of valuable specimens to 
his collection of Indian antiquities from Florida. Among other notable 
gifts of the year may be mentioned a large series of Indian implements, 
plants, birds and minerals, the collection of the late Dr. Charles Schaeffer, 
presented by Mrs. Schaeffer, a collection of ethnological material from 
Lieut. Frederick Schober, and numerous valuable specimens of mam- 
mals, birds and reptiles from the Zoological Society of Philadelphia. 
Several important collections have also been secured by purchase. 
Besides the work detailed in the appended reports of the Sections, 
Mr. Fowler has continued the arrangement and identification of the 
fishes, and made numerous local collections. 
Dr. Moore has cared for and added to the helminthological collection. 
Dr. Pilsbry and Mr. Vanatta have made important advances in the 
identification and arrangement of the mollusca. The report of the 
Special Curator of this department is added. 
Mr. Rehn has cleaned the greater part of the small mammal skulls 
belonging to. the Rhoads and Bunnell collections, upward of 3,000 being 
thus added to the study series.
