1916.] NATURAL SCIENCES OF PHILADELPHIA. 621 



Many ornithologists have studied the collections at the Academy 

 and specimens have been loaned to J. P. Chapin, W. E. C. Todd, 

 and Albert Laessle. 



Reptiles and Batrachians. 



Mr. Henry W. Fowler has during the year catalogued 350 specimens 

 and given a careful supervision to the collection, replenishing alcohol 

 when necessary. 



He has also conducted extensive field work in Pennsylvania, New 

 Jersey, Maryland, and Virginia, which resulted in securing forty 

 local collections of reptiles, batrachians and fishes. Two papers 

 w r ere published during the year on cold-blooded vertebrates in the 

 Academy collection and two others are now in preparation. 



Fishes. 



This department has also been under Mr. Fowler's care and much 

 of the work of collecting and publication just described covers the 

 fishes also. Twelve large local collections of Pennsylvania fishes, 

 presented by Mrs. E. S. and W. I. Mattern, deserve special mention, 

 as w r ell as a number of mounted game fishes, the gift of Mr. A. B. 

 Loeb. 



Mollusks. 



Dr. Henry A. Pilsbry, Special Curator, reports specimens received 

 from 56 persons and institutions. Among the more interesting 

 accessions are a series of the mollusks collected this year in Utah 

 and Idaho by Messrs. Junius Henderson and L. E. Daniels; several 

 hundred lots from Maine, taken by Mr. Bayard Long; a large series 

 of Californian shells from Mrs. Oldroyd, and collections from 

 Guatemala and Panama from Messrs. S. N. Rhoads and D. E. 

 Harrower, respectively. 



Studies on the Pupillida? for a monograph of the family have 

 occupied most of the time of the Special Curator. Considerable 

 additions to our collection of these shells have been obtained from 

 various correspondents. 



Mr. E. G. Vanatta has been occupied chiefly with the determina- 

 tion of specimens for correspondents and with labelling and arranging 

 accessions to the museum. Miss Caroline Ziegler has continued the 

 work of cataloguing the collection. 



The collection has been consulted by various visiting naturalists, 

 and specimens have been loaned for study to Bryant Walker, Paul 

 Bartsch, and S. S. Berry.
