MUSEUM OF COMPARATIVE ZOOLOGY. 19 



REPORT ON THE MAMMALS. 



By Outram Bangs. 



The collections of Mammals now in the possession of the Museum 

 have been incorporated in a single series and a large collection of 

 duplicates has been separated for purposes of exchange. Many of 

 the duplicates are topotypes of forms I have described. A system 

 of exchanges has already been inaugurated which promises to 

 bring to the Museum much material not now represented in the 

 collections. Every effort is being made to make the collection a 

 representative study series of the Mammalia of the world, and it is 

 hoped that the collection will soon take its place among those of 

 the larger Museums. Many of the old skins have been made over, 

 the skulls removed and cleaned, so that it can be said that nearly 

 all of the material is in modern form and in first-class condition. 

 A number of air-tight storage cases of an improved form have 

 been constructed which have proven most satisfactory. 



The accessions to the collections are as follows : — 



The Bangs collection, mostly North American, numbering about 

 ten thousand specimens. Eight specimens from the Liu Kiu Islands, 

 including one type ; purchased. Twenty-one specimens of Puto- 

 rius, Dicrostonyx, and Lemmus from Point Barrow, Alaska, from 

 E. A. Mcllhenny ; purchased. Sixty-two skins collected by W. W. 

 Brown, Jr., in Divala Chirigui, Central America; presented by 

 Messrs. E. A. and 0. Bangs. Eleven skins from San Julian, 

 Venezuela ; presented by Capt. Wirt Robinson, U. S. A. Three 

 hundred and thirty skins collected by W. W. Brown, Jr., in the 

 Cordillera de Chirigui ; presented by Messrs. E. A. and 0. Bangs. 

 Other gifts have been given by A. G-. Dorr, R. H. Howe, Jr., C. P. 

 Jaynes, J. C. Shattuck, and Commander J. F. Moser, U. S. N. 



Material has been loaned to J. A. Allen, G. M. Allen, M. W. 

 Lyon, Jr., C. Hart Merriam, G. S. Miller, Jr., E. W. Nelson, and
