Family : PlEURODELIDAE. 



Dietnyctylus viridescens viridescens Raf. Toes 4-5, outer and inner 

 toes on hind foot rudimentary. Body above brown to olive, below yellowish. 

 Sides of adults with a series of large red spots, each encircled by a brown 

 ring. Below speckled with brown. Tail much compressed. Length 2>/4 

 inches. 



This sub-species is the common Newt of the Eastern States. 

 It is altogether aquatic, living in springs and deep running water. 

 In Ohio it is known from but one specimen from Lancaster, 

 mentioned by Wilcox ('91). 



In O. S. U. Mus., collected by E. V. Wilcox at Lancaster. 



Diemyctylus viridescens miniatus Raf. Similar to above, but ground 

 color, brick red. The red coloring of the lateral spots therefore is less con- 

 spicuous. The skin is rough, being covered with minute warts. Tail cylin- 

 drical. 



This is the common representative of the genus in the State. 

 It is never found in numbers but may be looked for in all parts 

 of Ohio. It occurs under rotten logs, in stumps and under stones 

 often far from water. The form is very conspicuous and stands 

 out from its environment very decidedly. It is not active in its 

 movements and may be readily captured. The tongue is free 

 and by means of that organ the food is obtained in the manner 

 of the common toad. 



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

 In Oberlin College by Lynds Jones from Lorain Co.; in Cin. Soc. Nat. His., 

 collected by E. E. Masterman at New London ; in O. S. U. Mus., collected 

 at Lancaster by E. V. Wilcox ; at Clintonville by J. C. Bridwell, and at 

 Newton Falls by the author. Also reported from Sugar Grove. 



Order: SALJENTIA Laurenti. 



This order includes the toads and frogs, i. e. , the tailless 

 Batrachia. The larvae are similar to those of the order just 

 completed, being provided with gills and spending their larval 

 period in water, feeding on vegetable matter. They are commonly 

 known as "tad-poles." When metamorphosis takes place, they 

 leave the water, losing the gills and the tail and gaining four 

 strong legs and a pair of lungs ; the alimentary canal becomes 

 shortened for a carnivorous habit. The order is divisible on 

 anatomical and physiological grounds into two tribes, viz :
