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 
megalotis or with m. pallescens. 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 Alleghenies. 
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 pallescens 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. 
Specumens 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.
