BATRACHIANS AND REPTILES OF OHIO. 1 23 



Class: REPTILIA. 



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 L,inton, 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: SOUAMATA 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.
