A STUDY OF THE MAMMALIAN GENUS CHILONYCTERIS. 



BY JAMES A. G. REHN. 



The following paper is the result of a study of an exceedingly inter- 

 esting series of one hundred and three specimens, of which twenty- 

 four w^ere preserved as skins, the remainder being in alcohol. Of this 

 representation forty-three were from the collection of the United 

 States National Museum, thirty-six from that of the Biological Survey, 

 eighteen from the American Museum of Natural History, and a smal 

 but exceedingly important series from the collection of the Academy. 



The author wishes to express his indebtedness to Mr. Gerrit S. Miller, 

 Jr., of the United States National Museum, Dr. C. Hart IMerriam, of 

 the Biological Survey, and Dr. J. A. Allen of the American Museum 

 of Natural History, for their kindness in securing and permitting the 

 use of specimens from the collections under their charge.
