furnished with mahogany book cases, the gift of ]VIrs. Charles Schaeffcr, 

 who has hkewise 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 Archaeological department and 

 the w^oodwork 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 Ligiius 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 dejiartment 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.
