Head broad and flattened, contained in the length of head and body 

 about three times. Snout rounded. Eyes large aud protruding. 

 Vomerine teeth in two patches, the posterior edges of which project 

 behind the line joining the hinder borders of the choanse. Tympanic 

 disk usually as large as the eye, sometimes larger ; occasionally, 

 especially in the females, somewhat smaller than the eye. A groove 

 passes from the back of the eye over the tympanic disk and downward 

 behind it, and terminates in front of the arm. There are present two 

 dorso-lateral glandular folds. These start at the upper eyelids aud run 

 back to the pelvic region. Over the tympanic disk a branch is given 

 off which passes down behind the disk and terminates over the arm. 

 The groove described above lies between the disk and the branch. The 

 skin of the back and sides is more or less rough. This roughness is 

 produced by minute, sharp-pointed, wart-like elevations, those along the 

 sides largest. 



Hind limb, when pressed to the side, bringing the heel between the 

 eye and snout. Third toe longer than the fifth. Toes webbed nearly to 

 the tips. Subarticular and one metatarsal tubercles moderately devel- 

 oped. 



Color above varying from greenish olive to brown ; in life often bright 

 green toward the head. On the back there are usually numerous small 

 nearly circular blotches of dark brown, and larger ones on the sides. 

 These are not spots, light bordered and definite, as those of jK. pipiens, 

 but look as if the color had run into the surrounding skin. The hind 

 legs are crossed by narrow bars or rows of spots. The hinder surface of 

 the thighs is granulated and of a yellow color, with spots and mottlings; 

 of black. The lower jaw and throat are marbled with brown, otherwise
