THIS is a very large species; equalling, if not 

 exceeding, the Bull Frog in size, and is of a pale 

 brown colour,' lighter beneath, and is marked all 

 over, except on the head, with small, oval, ches- 

 nut-coloured tubercles : the head is smooth and 

 veined with a few slight reticular marks, and from 

 the nostrils to the shoulders, and thence down 

 each side the back, run a pair of paler lines, as in 

 many others of this genus. On each shoulder, as 

 it were, or beyond the head, is a large and some- 

 what oval eminence or projecting part, of a light 

 broxrn colour, and marked with numerous distinct 

 pores. These parts are, in reality, as Mr. Schnei- 

 der has observed, no other than the parotid glands, 

 which are more or less protuberant in all Toads, 

 but which in this seem more than commonly con- 

 spicuous, and may therefore be allowed to consti- 

 tute a part of the specific character. The feet are 

 destitute of webs, and the toes, which are four on 

 the fore feet, and five on the hind, have a slightly 

 orbicular termination, and are furnished with short 

 claws, resembling the human nails in miniature:
