SPECIES OF MAMMALS OF THE PACIFIC AREA 59 



inches long, the tail one and one-fourth to two and one-fourth 

 inches, and the forearm one and one-fourth to one and three- 

 fourths inches. 



The Galapagos Red Bat and the Hawaiian Hoary Bat be- 

 long to the same genus (Lasiurus), elsewhere restricted to 

 North and South America. They are characterized by a hairy 

 interfemoral membrane and short broad ears. The mainland 

 species migrate long distances, often across considerable bodies 

 of water. Thus they are bats that may readily be carried by 

 storms far from their usual ranges. Even so, the ancestors 

 of the Hawaiian hoary bat must have traveled twenty-four hun- 

 dred miles from the North American coast, without chance to 

 rest or secure food on the way — a remarkable record of en- 

 durance. 



Bent-winged or Long-fingered Bats. 

 Subfamily Miniopterin^ 

 Bent-winged Bats (Miniopterus), confined to a single genus, 

 are found in Africa, southern Europe, and Asia, extending 

 north to Japan and east to Australia and the Loyalty Islands. 

 The first joint of the third finger is only about one-third as 

 long as the distal joint, and this last joint is bent under and 

 back against the undersurface of the metacarpal in repose. 

 The crown of the head is high and dome-like. There are five 

 cheek-teeth in each upper jaw, counting from behind the canine, 

 and six in the lower jaw. Most species, though small, have large 

 wings : the head and body measure from one and three-fourths 

 to two and one-half inches. The tail is about equal to the head 

 and body length, and the forearm varies from one and three- 

 eighths to two and one-eighth inches. 



TuBE-NOSED Insectivorous Bats. 

 Subfamily Murinin^ 

 Tube-nosed Insectivorous Bats (Murina, Harpiocephalus) 

 have the nostrils drawn out into tubes, much as in certain fruit
