from Washington and Oregon, received from Mr. John A. Allen; 
Antarctic shells of the Sir Ernest Shackleton Expedition, from 
Mr. John H. McFadden, and Mexican shells from C. R. Orcutt. 
Messrs. Clarence B. Moore, Morgan Hebard, S. S. Berry and others 
have made many gifts of southern and western shells, and Mr. 
Bayard Long has continued his collections in New Jersey. 
The John Ford collection of Olividce, purchased during the year, 
when added to that of the Academy, forms probably the most 
extensive series of these shells in any museum. 
With Mr. James H. Ferriss, the special curator spent the greater 
part of August and September in an exploration of the Black Range 
of New Mexico, obtaining large series of land mollusks, part of them 
new to science. 
W"e have also been favored with a complete series of the mollusks 
taken by Messrs. Junius Henderson and D. E. Daniels, who collected 
in many localities from Provo, Utah, to Franklin in southern Idaho. 
The study of Hawaiian material of the expedition of 1913 has 
been continued throughout the year. The family Tornatellinidce 
has been completed, and a monograph published in the Manual of 
Conchology, Volume XXIII. The proportion of unclescribed 
forms proved to be unusually large, the volume containing descrip¬ 
tions of 103 new species and 29 new subspecies. Dr. C. Montague 
Cooke, of the Bishop Museum, Honolulu, collaborated with the 
special curator in this work. 
Mr. E. G. Vanatta, assistant in the department, has been chiefly 
occupied in the determination and labelling of specimens received. 
Miss Caroline Ziegler has continued the work of cataloguing the 
collection. 
The Wheatley collection of fresh-water shells has been deposited 
by the University of Pennsylvania, and some progress has been made 
in cleaning, labelling and cataloguing the specimens. 
During the year the collections have been studied by Messrs. 
George H. Clapp, Frank M. Anderson, Drs. W. H. Dali and A. 
Olssen, while material has been loaned to Drs. W. H. Dali and Paul 
Bartsch, Messrs. Junius Henderson and J. B. Henderson. 
Insects. 
Dr. Henry Skinner, head of the department of Insects, reports 
that much of his time and that of Mr. E. T. Cresson, Jr., has been 
devoted to relaxing and mounting the new material acquired. Por¬ 
tions of the collection have also been rearranged in the new cases 
procured during the year.
