INDISTINCT TOAD. 171 



Amoenitates Academicce^ where it is said to be of 

 a subglobose form, extremely convex, of a wrinkled 

 but not tuberculated surface, clouded, and marked 

 by a palish longitudinal dorsal band, which is 

 sinuated on each side : the head very small, ob- 

 tuse, and immersed in the thorax : the toes of the 

 fore feet un webbed, without claws, and somewhat 

 tuberous or knotted beneath the joints : the toes

 the smaller species, scarcely exceeding half the 

 size of the common toad. The hind feet are 

 slightly palmated, though this circumstance is not 

 particularized in the Linngean description above 

 quoted. It is a native of Senegal and other parts 

 of Africa.

 the former ; having a thick roundish body, with 

 the head so blended in the general outline that
