lower austral habitat have been taken at Andrews in Cherokee 
Co. and near Franklin in Macon Co. The Green Lizard (lower 
austral) is also said to occur along the Little Tennessee River in 
Graham or Swain Counties, but this record is open to question. 
I At Weaverville, Buncombe County, the Big-eared Bat (lower 
austral) has been recorded. 
These exceptional records, while in our opinion not sufficiently 
numerous or consistent to change the course of the faunal lines as 
shown on the map, serve to emphasize the fact that no faunal 
lines or zones can be claimed to be absolute. Animals typical of 
one zone will occasionally wander into a neighboring zone. It is 
therefore not surprising to find a typically lower austral form as 
much as twenty to forty miles north or west of the faunal line, or 
on the other hand to find a distinctively upper austral form a 
similar distance east or south of this line, — and this overlapping 
of forms along the edges of the zones occurs with special frequency 
among those animals which move rapidly from place to place and 
which may therefore from hunger, fright or other causes become 
restless and wander out of their normal range. But it would be 
worthy of note if a distinctively upper austral form were found to 
occur regularly and in any degree of abundance, in the warmer 
parts of our state which are well within the Lower Austral zone as 
defined on our map. In this connection we would call attention 
to the localities of Cape Hatteras, Beaufort, Havelock (Lake Ellis) 
and Wilmington. From these four localities we get a total of 46 
characteristic records, every one of them lower austral. But when 
we go nearer to the line to the north and west as at Greenville, 
Tarboro and southeastern Bertie County, we strike scattering 
upper austral records. The few upper austral rocords for New 
Bern and Kinston are of such character as not to materially affect 
their standing as strictly lower austral localities. The presence 
of several lower austral records in the southern part of our moun- 
tain region is plainly attributable to the proximity of the Gulf 
coast only a few hundred miles to the south, whence characteristic 
forms no doubt migrate with more or less frequency up the 
streams or through the low mountain valleys, — while the high 
mountain ranges present many Alleghanian and even some Cana- 
dian forms. These conditions of life-zones normally opposed to
