RANIFORMIA. 



Ranula brevipalmata, sp. nov. 



Nearl}' allied to the B. affinis, but with the web of the posterior 

 digits only reaching the bases of the ultimate, or in the fourth 

 toe, the penultimate phalange. The membranum tympani is as 

 large as the eye (not orbit) ; and the nostril is near the end of 

 the muzzle. The extended hind limb brings the heel to the ante- 

 rior border of the orbit, instead of the end of the muzzle, as in 

 Pi, affinis. General color, olive ; below, white. Femora and 

 tibige marbled, with black behind.
