BATRACHIANS AND REPTILES OF OHIO. 121 



Rana palustris Le Conte. Similar in coloration to preceding save that 

 the dorsal blotches are arranged in two longitudinal series, each blotch 

 being approximately opposite its fellow. The livid green, however, is 

 replaced here with brownish or olive. Length 3 inches. 



The Swamp-frog is to be found in marshy places, but it is 

 frequently met with in high grass in fields and along roadsides. 

 It is much commoner than would be supposed as it is with diffi- 

 culty distinguished from its environment and unlike the foregoing 

 species, it remains quiet until almost touched. Common over the 

 entire State. 



Specimens in the U. S. Nat. Mus., recorded by Cope from Toledo. In 

 the O. S. U. Mus., collected by J C. Bridwell at Dublin and by E V. Wilcox 

 in Ottawa, Lawrence, Franklin and Delaware Cos. ; by the author at Sugar 

 Grove and Gypsum. 



*Rana septentrionalis Baird. Olive brown above, light yellow below. 

 Back with irregular streaks. Length i}4, inches. Skin smooth. Eye large. 



This species has never been taken within the limits of the 

 State, but owing to its range it very probably will be found in the 

 north-eastern or eastern portion. Its range is northward from 

 Minn, to N. Y. 



Rana clamata Daudin. Lniform brownish green, with faint black 

 spots. Below white. Ear large, as large as eye. First finger reaching end 

 of second. Length 3 inches. 



This is a heavier frog than any that have thus far been con- 

 sidered. It is somewhat gregarious, especially in spring and early 

 summer. It is never found far from water. This species is the 

 least noisy of the genus, its note being a miniature of the Bull- 

 frog's gutteral croak. The conspicuous lateral fold distinguishes 

 it from the Bull-frog. Abundant over the State. 



Specimens in the U. S. Nat. Mus., recorded by Cope from Columbus and 

 Portage and Highland Cos. In the O. S. U. Mus., collected by E. V. Wilcox 

 in Lawrence and Licking Cos. By the author at Vinton, Castalia, Newton 

 Falls and Chillicothe. 



Rana catesbiana Shaw. Lateral fold scarcely discernable. Above 

 brown to olive, interspersed with brownish blotches, sometimes running 

 together. Head bright green. Ear large. Toes with web reaching the 

 tips. Length 5-8 inches. 



This is the common Bull-frog, the largest of our frogs and 

 of the Batrachia in general. It is seldom seen but is to be heard
