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. 

 Baj^ard 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 moUusks, part of them 

 new to science. 



We 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 undescribed 

 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 stuched by Messrs. 

 George H. Clapp, Frank M. Anderson, Drs. W. H. Dall and A. 

 Olssen, wdiile material has been loaned to Drs. W. H. Dall 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.
