The Batrachians of the " Chevert " Expedition, 

 By William Macleay, F.L.S. 



The Batrachians collected during the cruise of the " Chevert," 

 are few in point of number, and belong exclusively to the section 

 of the Batrachia Anura, to which Dr. Gunther gives the name 

 Opisthoglossa. But though few, they are not without interest, 

 as exhibiting the complete dissimilarity between the Batrachian 

 Fauna of New Guinea and Australia. 



OPISTHOGLOSSA OXYDACTYLA. 



Ran aster, New Genus. 



Habit rather stout. Head large and rounded. Legs rather 

 short. Fingers and toes tapering, and slightly webbed, with 

 tubercular pads on the carpal and tarsal bones. Skin smooth. 

 Maxillary teeth conspicuous, acute, bicuspid, and sub-distant. 

 Vomerine teeth conspicuous and sub-distant, situated on a long, 

 straight, transverse ridge, sharply divided in the middle. Inner 

 nostrils rather large, and in front of the vomerine ridge. Tongue 

 largely notched behind. Tympanum distinct. Sacral vertebra 

 dilated. No paratoids. 



This genus will, I fancy, fall into Gunther's Family Discog- 

 lossidce. The most remarkable feature about it is the dentition ; 

 the teeth, both maxillary and vomerine, being comparatively 

 large and distant.
