106 BULL FROG. 



Catesby this species has been described by Kalm, 

 and other travellers. It is said to indicate the 

 approach of rain by its piping voice, during the 

 spring and beginning of summer. The ears in 

 the living animal have a bright gilded tinge, or 

 metallic gloss. A Frog much allied to the above, 

 and perhaps a variety, is described and figured by 

 Seba, vol. 2. p. 37. t. 37. but is said to be a na- 

 tive of Africa.

 many parts of North America, where it is known 

 by the name of the Bull Frog, its voice resembling

 Catesby, in his Natural History of Carolina, and 

 which he assures us w r as taken from a small rather 

 than a large specimen, seeming to measure about 

 eighteen inches from the nose to the end of the 

 hind feet. Its colour, on the upper parts, is a 

 dusky olive, or brownish, somewhat irregularly 

 marked with numerous deep-brown spots; while 

 the under parts are of a pale or whitish cast, with 

 a tincture of yellowish green, and marked with
