India. The Academy is again especially indebted to Messrs. E. 
S. and W. I. Mattern, who have presented collections of local fishes 
from various parts of Pennsylvania and New Jersey, aggregating 
5,000 specimens. On March 8, the second meeting of the American 
Society of Ichthyologists and Herpetologists was held at the Academy, 
which brought together specialists in these fields from various parts 
of the country and proved in every way most successful. 
Three papers dealing with the collections were published by Mr. 
Fowler during the year. Specimens were loaned to Dr. C. H. Eigen- 
mann. 
Mollusks. 
Dr. Henry A. Pilsbry, Special Curator of Mollusks, states that 
specimens have been received from 82 persons and institutions since 
the last report. Among other valuable gifts were large accessions to 
the collection of Hawaiian Mollusca, received from Mr. D. Thaanum, 
of Hilo, Hawaii, and from Prof, and Mrs. W. A. Bryan, of Honolulu, 
who spent several months at the Academy studying the collections. 
Also the important Rocky Mountain and California material from 
Prof. Junius Henderson and Mr. Jas. H. Ferriss. 
New cases installed last year have permitted the expansion and 
rearrangement of the whole study series of shells, which is now in 
excellent order. 
Dr. Pilsbry has completed the first volume of the “Monograph 
of the Pupillidse,” begun last year, the final number being now 
in press. He has also published three papers on the anatomy of 
West American snails, and in collaboration with Mr. Ferriss, a 
study of the mollusks of the Black Range, New r Mexico. Also 
papers on Hawaiian marine shells. 
Mr. Vanatta has been occupied with labeling and arranging 
accessions to the collection and in determining specimens for corres¬ 
pondents. Miss Ziegler has made good progress in the long task 
of cataloguing the collection of shells. 
The collection has been extensively used by visiting naturalists. 
Specimens have been loaned to Dr. Paul Bartsch, Prof. A. E. Verrill 
and E. P. Chase. 
Insects. 
In the department of Entomology, Dr. Henry Skinner reports 
that during the year, two thousand three hundred and eighty-six 
insects have been received, and the greater part of them has been 
relaxed, mounted and placed in the cabinets.
