ALLEN: BATS OF THE GENUS CORYNORHINUS. 351 



it further from any of the forms occurring in the United States. I 

 have found no evidence that it intergrades at any point with true 

 megalofis or with m. paUescens. In North Carolina, a typical specimen 

 in the collection of Mr. Morton L. Church, was captured at Marshall, 

 in the extreme western end of the State, while from extreme western 

 Virginia comes megalotis, without any sign of intergradation, though 

 the localities are not far distant on opposite sides of the AUeghenies. 

 Since writing the above, I have also examined a skin of macrotis from 

 Mitchell, Ind., which is of interest as indicating not only the north- 

 ward limit of the species' range in east central United States, but also 

 that it keeps distinct from megalotis where the two occur together. 

 Alcoholic specimens, if in good condition, show the white-tipped hair 

 with its dark bases on the belly, and can usually be distinguished by 

 this character. How far to the westward this bat ranges is as yet 

 unknown. It is found in Louisiana and northward into Arkansas 

 and Indiana but has not yet been discovered in eastern Texas al- 

 though paUescens is recorded from western Texas. If this apparent 

 hiatus shall prove to be real, it would indicate that the range of 

 macrotis is fairly distinct from that of megalotis and its races. The 

 present evidence therefore shows that macrotis constitutes a species 

 distinct from the latter, though closely allied and of similar struc- 

 ture. It is characteristic of the Lower Austral life zone. 



Specimens examined. — The following specimens have been studied, 

 a total of nineteen. 



North Carolina: Marshall, 1 (M. L. Church Coll.); ten miles 

 northwest of Taylorsville, 2 (N. C. Coll. Agric). 

 South Carolina: Society Hill, 2 (U. S. N. M.). 

 No locality, 2 (U. S. N. M.). 

 Georgia: Kesler, Early Co., 1 (M. C. Z.). 



Young Harris, Union Co., 1 (Biol. Surv.). 

 ? Riceboro, Liberty Co., 2 skulls (U. S. N. M.). These 

 specimens were collected by LeConte, and though with- 

 out record of locality, may have come from his planta- 

 tion. 

 Alabama: Huntsville, 1 (Biol. Surv.). 



Leighton, 1 (Biol. Surv.). 

 Louisiana: Houma, 4 (Biol. Surv.). 

 Arkansas: Osage River, 1 (M. C. Z.). 

 Indiana: Mitchell, 1 (Ind. Univ.). 



In addition, it has been recorded from 

 Virginia: Dismal Swamp.
