Description. The head is elongated, and bronzed above; the snout is pointed. 

 The upper jaw is bright green, which colour is continued under the eye and 

 tympanum to the shoulder. The lower jaw is white, marked with dusky spots or 

 bars; these form an indistinct band that is lost about the anterior extremity. 

 The nostrils are lateral, and rather nearer the snout than in the Rana fontinalis. 

 The eyes are large and prominent, the pupil is black, the iris golden, beautifully 

 reticulated with black, and has an inner margin of bright yellow. The tympanum 

 is very large, bronzed, with a small spot of lighter colour in its centre. The body 

 is long, slender and delicate; olive colour or bronzed in front, and dusky, approach- 

 ing to black, behind, where it is slightly granulated; a cuticular fold, elevated to 

 form a ridge, begins behind each orbit, runs along the body, and is lost near the 

 posterior extremities. The whole surface of the throat and abdomen is silvery- 

 white.
