BATUACIIIA SALIICNIIA. 23 



lU. LIMNOCHARIS. 



Tongiie oval, entire, hinder edge free. Teeth ? Nose truncated. 



Tympanum conspicuous, circular. Sldn all smooth. Fingers free. 

 Toes webbed at the base (Bell). 



Bell describes the dentition thus: "Palatine teeth in two small 

 groups, one in a line contiguous with the front margin of the inner 

 nostrils, and a second at some distance behind them, close within the 

 rise of the maxillary arch." As far as I can sec, there were no 

 palatine teeth at all ; liut if they arc supposed to be lost, they must 

 have been implanted in a scries in front of the inner nostrils, much 

 interrupted in tlic middle. The second scries is merely imaginary, 

 and nothing more than the shai-p, quite smooth i-idge of the os pa- 

 latinimi. The snout tnineated, produced beyond the mouth ; the 

 maxillaiy arch is angularly bent, so as to fonn a straight front 

 series of maxillary teeth. Otherwise the specimen is not in such 

 a condition as to allow me to give my own diagnosis of this 

 Batrachian.
