M. giyas, as is proved by comparing it with Blyth's description. It 

 agrees in every particular with Giinther's description. Blyth ob- 

 serves that the young have the head proportionally less broad than 

 in the adult, which is well illustrated by his specimens.

Rana crassa, Jerdon, Journ. As. Soc. Bengal, 1853, xxii. p. 531 ; 

 Theobald, Cat. Rept. As. Soc. Museum, p. 79. 



This species, as observed by Theobald, is closely allied to It, tigrina, 

 from which it is distinguished by its more obtuse and shorter snout 

 and conspicuously broader occiput. Its metatarsal tubercle is pro- 

 portionally larger, stronger, and more crescentic than in R. tigrina, 

 resembling the shovel-shaped tubercle of Pyocephalus. Dr. Jerdon 

 regards it as allied to R. kuhlii, — a comparison which would seem 

 to indicate that he had never identified R. kuhlii ; for R. crassa has 

 the naked tympanum of R. tigrina, wants the fang-like apophyses 

 of R. kuhlii, and has the strongly developed vomerine ridges of the 

 former species. 



Snout rather short, and not so pointed as in R. tigrina. ' Occiput 

 broad, the breadth across the gape being longer than the head. 

 Loreal region concave, shelving outwards." Nostrils oval, nearer the 

 snout than halfway between the snout and the eye. Tympanum 

 distinct, smaller than the eye. Eustachian tubes large, larger than 

 the choanse. Vomerines 12 to 15, on two oblique prominent ridges 

 from the anterior inner angle of the choante, converging behind, but 

 separated by a moderate interval. Tongue of moderate size, cordate. 

 No fang-like apophyses on the lower jaw. Back with short longi- 

 tudinal folds : a few tubercles on the sacral region. A fold from 

 the eye over the tympanum to the shoulder ; a fold between the 

 eyelids, and a very rudimentary one along the inside of the tarsus, 

 and a fringe along the fifth toe. Hind limbs stout, rather short, the 

 distance between the vent and the metatarsal tubercle being the 

 length of the body or a little less. Toes fully webbed, the mem- 

 brane hardly reaching to the extremity of the fourth toe. A pro- 

 minent crescentic sharp-edged tubercle at the base of the first toe. 

 Fingers and toes with the same proportional length as in R. tigrina. 



Brown above (spirit specimens), spotted with darker in the same 

 way as in R. tigrina. Under surface yellowish, obscurely spotted on 

 the chin and throat ; a narrow brown longitudinal streak on the same 

 region in youngish males. Lips barred with blackish ; vocal sacs of 

 males dusky externally. One out of four with a vertebral band.

Dr. Jerdon describes the body as greenish above, with dusky 

 markings, and states that the Frog was rare — found in a few tanks in 

 the Carnatic. The specimens of this notice are from Ceylon.
