COPE ON THE BATBACniA SALIENTIA. 117 



a. Tongue deeply emarginate posteriorly. 

 Terminal phalanges short ; transverse limb long ; 

 tongue without median inferior prominence ; 

 no dorso-lateral glandular dermal folds ; vo- 

 merine teeth Amolops* 



Terminal phalanges slender with short transverse 

 limb ; tongue without median process. No 

 dorso-lateral folds nor vomerine teeth. Pre- 

 frontals entirely in contact with each other and 



with frontoparietals Heteroglossa. 



Terminal phalanges slender, with short transverse 

 limb ; tongue with median inferior prominence ; 

 no dorso-lateral folds nor vomerine teeth ; eth- 

 moid widely separating prefrontals, and these 



from frontoparietals Sfaiirois,f 



Phalanges as above ; tongue with median inferior 

 prominence or thickening;): ; a longitudinal glan- 

 dular fold on each side of the back ; vomerine 



teeth Hylarana, 



Phalanges elongate, acute, or slightly dilated at tip ; 

 glandular folds present or absent ; voraeriae 



teeth Bana. 



Closely following Rana is Dicroglossus, Grthr. which wants vo- 

 merine teeth. This leads at once to Oxyglossus, Tschudi, also with- 

 out teeth on the vomer, and further characterized by its having — 



aa. Tongue elongate, entire posteriorly, in one species pointed ; 

 a structure foreshadowed by the strong median inferior prominence 

 of that of Dicroglossus adolphi.§ Nearly allied to Hana (in Sect, a 

 again) is Soplohafrachus, Peters, which is provided with a fossorial 

 metatarsal spur, and immediately precedes the genus Pyxiceplialus,\\ 

 the burrowing type in this family. 



* The only species is Polypedates afcjlianus of Giinther, which is a Hylarana 

 with the physiognomy of a Polypedates. 



t Embraces I.xahis nafotor, I. gtcttaf us, a,nd HyperoUiis 'plicatus oi Giinther. 



X Very slight in H. macularia and H. albolahris. 



§ It appears to me that Sterjiorhynchus natalensis, Smith {{DicToglossus angtis- 

 tirostns, Cope), belongs to this genus. In case it does not, it must receive 

 Giinther's name Phri/nobatracJiux, and not the later Leptoparius, Peters, given 

 on account of the preoccupation of Sfenorhynchus. 



II In a skeleton of P. adspersns, in the Mus. Brit., the o. iliaca are anomalously 

 attached to a tenth A^ertebra, which is attached by tsvo cotyloid cavities to the ninth, 

 and by two condyles to the coccygeal style.
