136 Frogs of the Okefinokee Swamp 



this specimen (No. 6575) the supraorbital crests are lower, the furrow between 

 them shallow and the two ends merge across the middle line and thus form 

 an ovate bony-like plate between the eyes with the apex at the nostrils and 

 the base on a line of the anterior ends of the parotoids. At right angles to the 

 front of the supraorbital knob a ridge extends to a point just opposite the 

 end of the eyelid; here the ridge sends a branch downward 1/3 of the way 

 in front of the tympanum and sends another ridge backward over the tym- 

 panum to the parotoid; tympanic disk distinct, the cephalic border more 

 sharply defined than the caudal edge. Parotoid in some narrow and elongate, 

 in others shorter; in some reniform, in others oval; upper jaw slightly to de- 

 cidedly emarginate; head smooth; upper eyelid with small warts; back and 

 hind limbs with fine warts ; a spinose group above the arm insertion ; forearm 

 with coarse granulations; under parts granulate; 3rd finger slightly longer than 

 the first; 2nd finger longer than the 4th; tongue elliptical.
