ly at Raleigh, while the Florida Terrapin, (a very decidedly lower 
austral form) has been taken in north-west Johnston county, but 
is not known at Raleigh. This gives further warrant for running 
the dividing line directly through Raleigh. 
The line, passing between Cary and Apex, runs straight to 
Charlotte. Southern Pines, many of whose insects are known, 
shows strong lower austral affinities, while Stanly and Cabarrus 
counties each contribute one lower austral record. As Salisbury 
and Statesville both show records which would tend to exclude 
them from the lower austral zone, we have run the line straight 
to Charlotte so as to leave these points in the upper austral, but 
including parts of both Stanly and Cabarrus counties in the lower 
austral. 
From Charlotte we have run the line slightly south of west, so 
that it crosses the South Carolina line at or near Tryon in Polk 
County. This latter locality seems to be (biologically) one of the 
most remarkable in the state. Its vicinity within a radius of a 
few miles is so varied in elevation and temperature that we have 
records of lower austral, upper austral, and Alleghanian forms, 
and there may be an infusion of strictly Canadian forms on the 
tops of the higher mountains of that locality. Of the strictly 
lower austral forms known at Tryon we may mention the Green 
Lizard, and a species of true Scorpion, the latter having never yet 
been taken at any other place in the state. 
It may be well to mention a few rather exceptional records. 
Coopers Lemming, — recorded as an inhabitant of sphagnum 
swamps which are generally considered to present Alleghanian 
tendencies, — has been taken at Chapanoke in Perquimmans county. 
The Diamond Rattle-snake, — considered to be a decidedly lower 
austral form, — has been recorded at Jackson, Northhampton Co. 
The Red-backed Salamander, — not known at Raleigh and a dis- 
tinctively upper austral form, — has been taken at Greenville, Pitt 
Co. At Kinston the Wood-Frog and Pickerel Frog (both consid- 
ered to be upper austral species) have been taken. The Weasel 
(upper austral) has been taken at New Bern. The Glass Snake, — 
a typically lower austral form, — has been taken at Statesville. 
In Transylvania county there is record of the Mole Salamander, 
which is a distinctively lower austral form. Insects of normally
