BATRACHIAANOURA. 71 



oblong or a circular, white spot on the shoulder. From beneath the 

 angle of the mouth, a brownish streak extends to the arm. The legs 

 are more distinctly maculated than the body, and upon the hind ones 

 the blotches assume a transverse aspect, with intervening yellowish- 

 white spots. The sides of the abdomen are greyish-brown, vermi- 

 culated with whitish. The inferior surface of the head and belly is 

 dull yellowish- white, inconspicuously clouded -, the legs beneath are 

 uniform reddish-brown.

Fam. bufo:n'idae.

Observ. — In this family, teeth are completely wanting ; the tongue 

 is never emarginated or bifurcated posteriorly, and in the genus Bufo, 

 by far the most numerous in species, are to be observed the so-called 

 parotid glands. In the latter genus, also, we find some species the 

 toes of which are palmated ; whilst in others they are entirely free, as 

 is the case with the other genera, Rhmoderma excepted. As a general 

 rule, the skin is warty or verrucose to a degree never observed in either 

 Ranoids or Hyloids.
