material received, numlKn-ing several hundred specimens, of which 

 about 100 have been catalogued. 



The stuffed reptiles of the old collection, as well as the reptilian 

 osteological material, have been gathered together in a room on the 

 fourth floor, where they are readily accessible. Specimens have 

 been loaned to Dr. L. Stejneger for study. 



Fishes. 



The ichthyological collection has also been under Mr. Fowler's 

 care. He has examined the main alcoholic collection and prepared, 

 identified and labelled all the specimens obtained during the year, 

 cataloguing some 2,600 individuals. Numerous local trips that he 

 has taken have added large series of Pennsylvania and New Jersey 

 fishes to the collection. 



He has also studied critically the large group of catfishes and 

 related forms contained in the Museum and has a report on them 

 now in preparation. Papers have been published on Greenland, 

 British Guianan, and local fishes in the Academy's Proceedings. 



MOLLUSKS. 



Dr. Henry A. Pilsbry, special curator of this department, reports 

 that accessions have been received during the year from 69 persons 

 and institutions. No small part of his time, as well as that of Mr. 

 E. G. Vanatta, has been taken up in determining specimens for 

 correspondents, and while this work is rendered freely by the 

 Academy, as a service it owes to the public, it is abundantly repaid 

 by the gifts of desired specimens. 



Although no expeditions have been undertaken during the year 

 for this department, Messrs. Ferriss and Daniels have shared the 

 results of their summer's collecting in Arizona, covering a district 

 not before worked for mollusks, and local collecting trips by members 

 of the Museum staff have added some valuable material. 



Considerable progress has been made in determining and labelling 

 the Hawaiian material collected by Dr. Pilsbry in 1913; the assorting 

 of mixed lots having been completed, so that all species not yet 

 determined are available for convenient study. The study and 

 arrangement of the Achatinellidce have been completed. 



The series of American land shells and of land operculates have 

 been cleaned and catalogued by Miss Caroline Ziegler, who has 

 also been occupied with assorting material received from various 

 sources.
