everywhere, but especially in ravines and around rocky streams. 
They are not aquatic, their eggs being laid under logs, etc., away 
from water. The adults are to be found in comparatively dry 
places under rotten wood and stones. 
Specimens in the U. S. Nat. Mus., recorded by Cope from Ripley and 
Lancaster. In the Cin. Soc. Nat. His., collected by Dr. Lindahl at Cincin- 
nati; in Oberlin College, by Lynds Jones in Lorain Co.; in O. S$. U. Mus., 
by E. V. Wilcox at Sugar Grove and Morgan Co.; by the author at Youngs- 
town, Chillicothe, Worthington, Columbus, Nelsonville and in Licking Co. 
Plethodon glutinosus Green. Form stout, little distinction between 
head, body and tail. Metallic blue above, spotted with specks of silver. 
Below lighter, similar in appearance to the preceding. Inner toes developed. 
Costal grooves 14. Length 6 inches. 
This species may be confused with the sub-species /Yethodon 
cinereus or with Amblystoma jeffersonianum. From them, how- 
ever, it may be distinguished by the presence of fourteen costal 
grooves. It is purely a terrestrial species, a denizen of the 
mountains and hills. It is to be found under stones and logs on 
the sides of hills, often far from water, Smith (’82): ‘‘ They 
hibernate beneath wet logs and go into the water to breed in 
April, in Georgia and probably a little later in our limits.”’ 
Hay (’92) considers them wholly terrestrial, in all probability. 
It is very common in central, eastern and southern parts of 
the State.

Newton Falls and Sugar Grove. 
Gyrinophilus porphyriticus Green. Yellow to brown above; sides 
light, with a reddish tinge. Light or grey streaks and blotches on back. 
Costal furrows 14. ‘Tail compressed, with a well developed keel. Body 
flattened. A light line from eye to edge of upper jaw. Below not spotted. 
Length 6% inches. 
Rare in the State. Intrusions are resented by snapping, and 
if carricd to extremes, by violent contortions. It is, however, 
utterly harmless. Smith (’82) gives it as aquatic, being found 
under logs in damp woods and in water. The adults are gen- 
erally concealed, the larvae being more readily found.
