what more elongate aud always less convex, If to 1| times as long as 

 broad,* its depth equal to the distance between the anterior corner of 

 the eye and the tympanum, its length 3f to 4} times in length to vent 

 in males, 4h to 5 times in females ; snout less obtuse, as long as the 

 postorbital part of the head or slightly less ; cheeks more or less

 males often very uneven or rough. f Neck usually a little constricted. 

 The hind limb reaches between the wrist of the adpressed fore limb
