Similar to R. m. macrognathus Boulenger, but differing in 

 the shorter leg, the heels not, or only just touching each other when 

 the limbs are folded at right angles to the body ; and in the longer 

 postorbitai swelling, which extends as far as a line connecting 

 the posterior borders of the tympana.

 greyer below. None has a vertebral stripe. 



Five males and one female examined. This frog was found 

 along the banks of the Kronfa river, hiding among damp leaves at 

 the water's edge.
