COPE ON THE BATRACni^ SALIENTIA. 113 



V. Toes webbed, terminal phalanges simple, very long. A fronto- 

 parietal fontanelle ; superior ethmoid plate much developed 

 anteriorly, separating the oblique longitudinal prefrontals. 

 Xiphisternal basil piece broad, styliform. Manubrium short, 

 produced transversely. 

 Pupil erect ; head shortened in front . . Hylorhina.'^ 

 TI. Toes free, terminal phalanges simple, not prolonged. A fronto- 

 parietal fontanelle ; superior plate of ethmoid more or less 

 exposed anteriorly. Xiphisternal cartilage supported by a 

 fibro-cartilaginous basal plate or style. Manubrium very 

 weak. 



a. Inguinal glands. 

 Vomerine teeth ; no tarsal tubercle ; tongue 



round Pleurodema. 



Vomerine teeth ; a tarsal and two sharp 

 metatarsal tubercles ; tongue subcylin- 



drical Oompliohates. 



aa. No inguinal glands. 



h. Tongue sub cylindrical. 

 No vomerine teeth or tarsal tubercle . . Liuperus. 

 bh. Tongue round. 



c. Ethmoid plate well developed, produced be- 

 tween the prefrontals more or less exten- 

 sively. 

 Vomerine teeth in two short oblique rows Sorboroccetes.f 

 Vomerine teeth in one long transverse row ; 



prefrontals well separated Lyjnnodynastes. 



cc. Ethmoid plate entirely cartilaginous. 



Prefrontals separate Eusophus.X 



VII. Toes free, terminal phalanges simple. A fronto-parietal fon- 

 tanelle. Prefrontals slightly or not in contact. Xiphisternum 

 narrow, weak, cartilaginous throughout ; sacral diapophyses 

 usually directed upwards, and often slightly dilated. 



* This genus embraces the Cystignathus ceneus of ' Gay's Chili,' which is pro- 

 bably the same as Htjlorhhia sylvatica of Bell. 



t This genus will, as at present understood, include Cystignathus rosens of 

 Gay's ' Chili,' where the superior plate of the ethmoid is remarkably produced 

 beyond the separated prefrontals between the external nares, to the end of the 

 muzzle, forming, as in Atelopica Jiavescens, a spade-shaped vizier. The only speci- 

 mens of Borboroccetcs do not allow of a comparison in this respect. 



X Type, Cystignathus nodosus of the 'Erp. Generale.'
