204 DR. J. ANDERSON ON INDIAN REPTILES. [Feb. 21, 



on the thigh ; tympanum very distinct, nearly as large as the eye ; 

 parotoicls slightly longer than the head, elongately kidney-shaped, 

 moderately broad, not very prominent, without a black edge. Third 

 finger longer than the fourth ; toes half webbed, the membrane 

 prolonged along the toes as a fine fringe nearly to the tips. Meta- 

 carpus with two coloured rather small tubercles, the innermost one 

 being the largest. Numerous rather flat tubercles of different sizes, 

 each capped with a small horny papilla. 



Adults light greyish olive, with numerous dark olive-black spots, 

 communicating and producing a reticulated appearance ; spotted or 

 obscurely barred with the same colour on the limbs, and with an ob- 

 scure interrupted dark band between the eyes, and occasional indi- 

 stinct traces of a pale vertebral line ; below whitish. 



All the young specimens are various shades of olive-grey or brown, 

 whitish below. Length of adult 3 inches. 



Hab. Agra district. 



This species is closely allied to the European B. viridis, but its 

 tympanum is large and distinct. 



It appears to be common in the Agra district, where it is associ- 

 ated with B. melanostictus. With Psammosaurus griseus, this is 

 the second African reptile which has been added to the fauna of the 

 north-west within the last three or four years. Very little is known of 

 the reptiles of the dry desert country to the south-west of Delhi and 

 Agra ; but further researches will in all probability prove that many 

 more of its forms are African. 



The similarity of the markings of the adults of this species to 

 those of C'acopus breviceps is remarkable, and suggests that either 

 one or the other may be an instance of mimicry.

This remarkable Toad, which was referred by Blyth to Bombinator, 

 has neither maxillary nor vomerine teeth. It is very closely allied to 

 the true Toads, and only differs in its free toes and in its slightly 

 notched tongue, which, however, resembles that organ in Bufo 

 in its elongately ovate form, and in being free behind. It has no 

 cranial ridges ; and its parotoids, which stretch from the eye to 

 the shoulder, are very narrow and linear. Its Eustachian tubes are 

 not obsolete, as described by Theobald, but are very minute orifices 

 placed close to the angle of the mouth. The character on which 

 Theobald has founded the genus is an unfortunate one, as it is purely 

 sexual and peculiar to the male. It consists of two plate-like cal- 

 losities on either side of the thorax, thickly studded with minute 

 dark-brown granules, such as occur on the same region in B. liebigi
