32 EXTINCT AND VANISHING MAMMALS 



GALAPAGOS ISLANDS RED BAT 

 LASIURUS BRACHYOTIS (J. A. Allen) 



Atalapha brachyotis J. A. Allen, Bull. Amer. Mus. Nat. Hist., vol. 4, p. 47, Mar. 25, 

 1892 ("Chatham Island," Galapagos Islands). 



This, the only bat at present known from the Galapagos 

 Islands, is one of the red-bat group, found on the American 

 continents from north-temperate to south-temperate latitudes. 

 It is a smaller relative of the hoary bats of the American 

 continents and Hawaii and like them has a hairy tail-membrane, 

 short rounded ears, and only a single upper incisor. 



The Galapagos bat is said to resemble closely its mainland 

 representative in its rusty-red coloring and minutely frosted 

 tipping to the hairs, but the ears are smaller and the wings 

 slenderer, the dentition lighter, with shorter canines. Forearm 

 length, 39 mm. 



Of this bat almost nothing is known. Dr. George Baur, 

 who collected the type specimen about 50 years ago, wrote 

 at the time of its capture (Allen, 1892): "On Chatham Island, 

 at an elevation of about 1700 feet, where the hacienda is placed, 

 we observed bats nearly every evening." The specimen was the 

 only one he succeeded in capturing, and it is at present in the 

 Museum of Comparative Zoology (its skull, however, unfor- 

 tunately lost). Dr. Baur adds: "Bats have been observed on 

 Indefatigable Island by Dr. Habel, and I observed one on 

 South Albemarle." It is, of course, uncertain whether all 

 these represented the same species of bat. Red bats are 

 known to reach Bermuda in their migrations in eastern North 

 America, so that it is not surprising that this strong-flying 

 species should have reached the Galapagos at some distant 

 period. Whether it will continue to survive the arid conditions 

 and restriction of forest growth on the islands can not at present 

 be told. 



HAWAIIAN HOARY BAT; "OLEPE" 



LASIURUS SEMOTUS (H. Allen) 



Atalapha semota H. Allen, Proo. U. S. Nat. Mus., vol. 13, p. 173, Sept. , 1890 (Kauai, 



Hawaiian Islands). 

 SYNONYM: Lasiurus grayii in part, J. E. Gray, Proc. Zool. Soc. London, 1862, p. 143. 



This is the Hawaiian representative of the continental 

 hoary bat, which as a species ranges from north-temperate and 

 sub-boreal latitudes to south-temperate climates, thus covering
