SPECIES OF MAMMALS OF THE PACIFIC AREA 57 



Its muzzle is broad and swollen. The cheek-teeth, four above 

 and five below, are the same in number as in Eptesicus and 

 Vespertilio, and the canine has a small cusp near its posterior 

 base. This bat is found among the mountains of New Guinea. 

 It is intermediate in size between the last two kinds of bats, 

 the head and body about two and one-fourth inches, the tail 

 one and one-half inches, and the forearm about one and three- 

 eighths inches. 



The Sarawak Brown Bat (Hesperoptenus), light brown in 

 color, is hardly to be distinguished from Eptesicus except that 

 its inner incisor is two-pointed and the outer one is minute, 

 hardly visible above the gum. Only one specimen has ever been 

 found. It was collected many years ago in northwestern Bor- 

 neo. The head and body are two inches long, the tail about one 

 and one-half inches, and the forearm one and three-eighths 

 inches. 



The Club-footed or Flat-headed Bat {Tylonycteris) is 

 found in the Indian and Malay subregions from the mainland 

 to the Philippines, Celebes, and Timor. It has short wings and 

 a flattened head. The wrist and foot bear thickened pads, ap- 

 parently adhesive in function. Bats of this genus usually rest 

 during the day in bamboo stems, crawling into them through 

 narrow cracks. These bats include the smallest of the order. 

 The head and body varies from one and three-eighths to one 

 and seven-eighths inches, the tail from one to one and one- 

 half inches, and the forearm seven-eighths of an inch to one 

 and one-eighth inches. 



Broad-nosed Bats {Scot emus) are found in Africa, con- 

 tinental Asia, Australia, and New Guinea, but apparently this 

 genus does not occur on the Malaysian islands. The different 

 species are usually colored a uniform brown; some have pale 

 undersides. They have a single conical upper incisor on each 

 side. The cheek-teeth are four above, five below. The skull is 

 broad, more nearly square in outline, viewed from above, than 

 in related bats. The head and body lengths of the different
