No. 3. — Notes on Chiroptera. By Glover M. Allen. 



The collection of bats in the Museum of Comparative Zoology con- 

 tains upwards of 190 species, represented by skins, skeletal parts, and 

 alcoholic specimens. Many of these specimens are of unusual interest. 

 I have made the following notes while studying this material recently. 

 In the case of certain imperfectly known species detailed series of 

 measurements or other data of interest are given, and tive species are 

 described as new. 



Of especial note are the collections received from the Thayer Expedi- 

 tion to Brazil, made in 1865, under the direction of Louis Agassiz ; also 

 a considerable number of Indian bats sent at about the same time by 

 Rev. M. M. Carleton from northern India and the Koolloo Valley. More 

 recently a valuable series of alcoholic specimens from Java and Japan 

 was presented by Mr. Thomas Barbour, in part collected by himself in 

 1906-07. I am indebted to the authorities of the Museum of Compara- 

 tive Zoology for the privilege of making this report, and to the United 

 States National Museum, through Dr. M. W. Lyon, Jr., for the loan of 

 certain specimens. 



All measurements are in millimeters, and colors are after Ridgway's 

 Nomenclature of colors. I have followed the nomenclatui'e and order 

 adopted by Miller in his monograph on "The families and genera of 

 bats" (Bull. 57, U. S. Nat. Mus., 1907). 



PTBROPIDAE. 

 Cynopterus brachysoma Dobson. 



The collections of Mr. Thomas Barbour establish for the first time, apparently, 

 the occurrence of two species of Cynopterus in the island of Java. The larger of 

 these is clearly the Pteropus titthaecheilus of Temminck, noticed below ; the 

 smaller species is represented by five adult females and four immature specimens, 

 all from Buitenzorg. These I have with some hesitation referred to Cynopterus 

 brachysoma of Dobson, with the description of which they closely agree, notwith-
