The wide front and peculiar glands of this species readily distinguisli 

 them from all others members of the genus. Its range, like that of so 

 many other North American Batrachia aud reptiles, is confined to the 

 eastern region. It is found in every part of this, including the Flori- 

 dan and Texan districts.

Specimens from Cambridge, Mass., are nearly unicolor, while Flori- 

 dah forms are lightest aud most variegated ; the head seems to bo a 

 little broader and more obtuse. These forms graduate into the inter- 

 mediate and most common type. Mr. C. W. Hargitt (see American 

 Naturalist, June, 1888) has found it on the Island of Martha' Vine- 

 yard, a fact which indicates the comparatively late separation of that 

 island from the main land of Massachusetts.
