18 COMPARATIVE ZOOLOGY. [Apr. 



37. From Mr. R. L. Davis, Newtown, England, a set of prepared 

 European caterpillars and other objects for the biological collection, 

 above 100 specimens. — Bought. 



38. From W. C. Beecher, New York, Coleoptera collected at 

 Fort Bridger, 300 specimens. — Presented. 



39. From S. H. Scudder, Cambridge, Mass., Pseudoneuroptera 

 and Neuroptera from the White Mountains. 



Miss Harris and Miss Clark worked through the year in the 

 department, spreading about 4,600 butterflies and labelling 

 insects, and arranging Coleoptera for the collection. 



Mr. W. J. Hubbard, Mr. C. S. Minot, and Mr. A. Sher- 

 rif worked through the winter and spring in the department, 

 partly for the collection, partly for their own instruction. 



Exchanges are made chiefly with the naturalists publishing 

 materials belonging to the collection, and with several ento- 

 mologists in the United States and Europe. 



The arrangement of the collection was carried on in an ex- 

 tensive way for the biological collection only, now far the 

 largest existing. It was the chief subject for study in my 

 voyage during the last summer. Several important collections 

 of this kind, bought by Prof. L. Agassiz, are very soon to 

 arrive. 



Since November Mr. Gr. R. Crotch has taken charge of 

 the Coleoptera. The mounting and arrangement of the large 

 Pacific coast collection, made by himself, is completed. To 

 accomplish this extensive work, the whole time of gentlemen 

 and ladies in the department was given. In the beginning of 

 March, Mr. Crotch was obliged to leave the Museum on 

 account of his poor health. 



Mr. E. Schwarz, from Breslau, has been working since De- 

 cember in the department, has mounted the Pacific coast 

 collection, and arranged a large amount of alcoholic vials for 

 the biological collection. His collections of winter insects 

 for the Museum, around Cambridge, has given the surprising 

 number of about 400 species, mostly Microcoleoptera, a 

 number of them new for the North American fauna, even 

 several new genera. 



Mr. Faxon has taken charge of the Crustacea. He has been 

 mainly occupied in making preparations illustrating the struc-
