BATRACHIANS AND REPTILES OF OHIO. 123 
Class: ia P TEL) Ae 
But one fossil reptile is known from an Ohio formation, this 
being a portion of the anterior end of an animal together with a 
portion of the vertebral column and the right posterior leg, show- 
ing crux and tarsalia. ‘The specimen was taken at Linton, Ohio. 
It is considered by Cope as the only reptile positively identified 
from the Coal Measures and therefore the oldest known reptile. 
In speaking above’ regarding the fossil Batrachia, an attempt was 
made to correlate the horizon at Linton, from which the several 
specimens were taken, with the Permian. In case the identifica- 
tion is correct, the statement of Cope would not be true, since the 
Theromorpha embraces many families found in the Permian of 
both the old and new worlds. 
Order: THEROMORPHA Cope. 
family: PARIOTICHIDAE Cope. 
Isodectes punctulatus Cope, Proc. Amer. Phil. Soc., 36:88. 
Order: SQUAMATA Latr. 
family: IGUANIDAE. 
Sceloporous undulatus undulatus Latr. Above brownish olive, with 
undulating brown cross bars edged with livid green. Legs similarly trans- 
versely banded. Throat and sides of chest bright blue, scales keeled. Head 
somewhat flattened. Length 7 inches. 
The Pine-tree lizard is common in the non-glaciated region 
of Ohio, its range in the State being limited, in the main, by the 
glacial boundary. It is a beautiful object, a statement, could 
antipathy be overcome, no one would care to gainsay. It is 
extremely quick in its movements and therefore difficult to cap- 
ture. The vertebrae of the tail are so constructed that that 
appendage may be readily parted with, with whatever disadvant- 
age, gaining the life of its owner. 
This little animal is absolutely harmless and makes an excel- 
lent pet. 
Specimens in the ,U. S. Nat. Mus., recorded by Cope from Columbus. 
In Cin. Soc. Nat. His., collected by Dr. Lindahl at Cincinnati; in O. S. U. 
Mus., by J. S. Hine at Vinton, and by the author from Chillicothe and Fair- 
field Co. Also recorded from Sugar Grove.
