DESCRIPTION OF A NEW GENUS OF CYSTIGNATHOID 

 FROGS FROM NEW SOUTH WALES. 



By G. a. Boulenger. 



(Comniunicated by J. J. Fletcher). 



Phanerotis. 



Pupil horizontal. Tongue oval, entire and free behind. 

 Vomerine teeth in long transverse series behind the choanse. 

 Tympanum perfectly distinct. Fingers free, toes with a very 

 slight rudiment of web, the tips not dilated. Outer metatarsals 

 bound together. Onaosternum very small, cartilaginous ; sternum 

 a cartilaginous plate. Diapophyses of sacral vertebra slightly 

 dilated. Terminal phalanges simple. 



This new genus comes nearest to Cryptotis, Gthr., with which it 

 agrees in the horizontal pupil, the shape and attachment of the 

 tongue, the structure of the pectoral arch, and the dilated trans- 

 verse processes of the sacrum ; but it differs in the distinct ear, 

 and the arrangement of the vomerine teeth, by which latter 

 character it approaches Limnodynastes. The relations of the 

 Australian genera of the family Gystignathidm are shown in the 

 following table : —
