Reptiles and Fishes 
Mr. Henry W. Fowler who has continued in care of the col- 
lections reports that he has examined during the year the entire 
series of reptiles and batrachians and about a third of the fishes, 
and has replenished the alcohol wherever necessary, so that this 
part of the collection is now in excellent condition. 
He has identified all of the material received during the year 
and catalogued 73 reptiles and amphibians and 228 fishes. A paper 
has been prepared for publication on the sticklebacks, sea-horses 
and allied fishes in the Academy’s collection. 
Further notable additions are included in a collection of reptiles 
and fishes from Nicaragua from Dr. Theodore Bouchelle; and a 
collection of Formosan fishes from Dr. Masamitsu Oshima. 
Mollusks 
Dr. Henry A. Pilsbry, Special Curator of Mollusks, reports that 
gifts of mollusks have been received from 79 persons, the more 
interesting accessions being a series of Venezuelan shells from Dr. 
H. Burrington Baker, and Madeiran shells, partly received alive, 
from Prof. T. D. A. Cockerell. Messrs. Ferriss, Clarke, Malone, 
Dr. S. S. Berry, and others, have continued to add to our North 
American series. The Special Curator procured some thousands 
of specimens from Lake Champlain and the adjacent Adirondacks. 
Work on the monograph of Pupillidae has progressed to the com- 
pletion of the subfamily Pupillinae. 
Throughout the year Dr. C. Montague Cooke, of the Bishop 
Museum, Honolulu, has prosecuted his studies on the anatomy of 
Hawaiian land snails in the laboratory of the department. Dr. H. 
Burrington Baker, of the zoological staff of the University of 
Pennsylvania, has worked up collections made by him in Mexico 
and Venezuela, finding time also for comparative studies on the 
dentition of Helicinidae and Neritidae, the results of which have 
been submitted to the Academy for publication. 
Mr. Vanatta has rendered efficient service in taking care of 
new material, and in a re-arrangement of the collection of fresh 
water mussels, which had outgrown the space formerly allotted. 
Specimens have been loaned during the year to 12 naturalists in 
other institutions.
