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 w^as 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 ]\Ir. 

 Fowler during the year. Specimens w^ere loaned to Dr. C. H. Eigen- 

 mann. 



MOLLUSKS.

 specimens have been received from 82 persons and institutions since 

 the last report. Among other valuable gifts w-ere large accessions to 

 the collection of Hawaiian Mollusca, received from Mr. D. Thaanum, 

 of Hilo, Hawaii, and from Prof, and Mrs. W. A. Biyan, of Honolulu, 

 who spent several months at the Academy studying the collections. 

 Also the important Rockj^ Mountain and California material from 

 Prof. Junius Henderson and ]\Ir. Jas. H. Ferriss.

 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 j'ear, the final number being now

 and E. P. Chase.
