iJ82 New Species of Hyla and Rana, 



It is surprising that this species, so common in the part of 

 America that has been most visited by foreign naturalists, 

 has as yet been noticed by no one. It may have been con- 

 founded with the H. viridis of Europe, which, however, it 

 but little resembles. 



The animals comprised in the division of reptiles called 

 Batracian, have long claimed a considerable degree of atten- 

 tion from me, and I present indications of six new species, 

 which on a future occasion I shall more full}' describe, and 

 accompany with the necessary figures. 



1. Rana* fontinalis, or common spring frog ; colour above 

 varying from yellow green to dark olive, sometimes irregu- 

 larly spotted with dusky, particularly on the sides, with a 

 raised interrupted line extending from the eye towards 

 the hind part of the body. 



2. Rana* palustris, or marsh frog ; colour above pale brown, 

 with two longitudinal rows of dark brown spots on the 

 back, and the same number on the sides, hind part of the 

 thighs yellow, spotted with black. 



3. Rana* sylvatica, or wood frog ; colour above varying 

 from light to dark brown, with two interrupted longitudinal 

 lines of black, a dark brown stripe extending from the tip 

 of the nose through the eyes, and covering the auricles. 



4. Rana* pumila ; pale green ; back with a decurved line on 

 each side, bounded with dusky, head with a triangular 

 spot between the eyes, legs barred with dusky. 



5. Rana* gryllus, (Savanna cricket ;) above warty, colour 

 various, with a triangular spot of darker on the top of the 

 head between the eyes, and a paler line extending from the 

 apex of this spot to the vent, hind part of the thighs yellow- 

 ish or whitish, with one or two lines of dusky or brown. 



6. Rana* nigrita ; above black, speckled with small white 

 warts ; middle of the back cinereous with an interrupted 

 stripe of black, upper lips with a white line ; beneath 

 granulate whitish ; irides golden ; legs barred with whitish, 

 hind part of the thighs brown : hind legs very long.
