Some Notes on the Mammals of Mammoth Cave, Ky. 61 



Geographic distribution. Carolinian and Austroriparian 

 regions. 



Habitat. Similar to that of the preceding species. 



Habits. The Georgia Bat was found only in isolated 

 instances in parts of Mammoth Cave, and never closely asso- 

 ciated either with its own species or with the Brown Bat. It 

 was quickly distinguishable from the latter by its much 

 lighter color, and can be recognized by this feature at some 

 distance even by torch light. I found some of this species in 

 small caves in Tennessee, and Dr. H. Allen gives the measure- 

 ments of one taken in Short Cave, Kentucky, in his recent 

 Monograph.' 1 ' Dr. Allen there states that "it is often found in 

 collections associated with Vespertilio gryphus (V. lucifugus), 

 but it is not known to be collected in the same locality with 

 this species," a view which my experience, not only in Ken- 

 tucky, but in New Jersey also, proves untenable. 



Description. Size equal to or greater than V. lucifugus. 

 Color tawny or brownish gray, wing membranes blackish, 

 wing bones flesh colored. Anterior upper incisor bifid, 

 larger than second. There is a diastema between upper 

 incisors and canine, the latter closely followed by a rounded 

 conical premolar which touches the large sectorial pm. 2, and 

 the latter crowded upon m. 1. Only one specimen from the 

 cave is available. It measures in alar extent 225 millimeters ; 

 the total length of tail and body is 80, of the tail 35, of the 

 hind foot 8, and of the ear from crown 10.5. 



The apparent absence of other species of bats, especially 

 the large Brown Bat, A. fusca, and the Red Bat, A. borealis, 

 from Mammoth Cave is unaccountable to me, as they abound 

 in the region, and from their habit of roosting in attics and 

 outhouses the cave would seem to present most suitable 

 conditions. The Red Bat, however, is known to hide in trees 

 during the day time in warm weather, and may reside in the 

 cave only in winter.
