Habit stout, massive, especially in males. Head flat above in the 

 adult, 1^ to 1^ times as long as broad, its depth equal to the distance 

 between the anterior corner or the centre of the eye and the tympanum, 

 its length 3|- to 4 times in length to vent in males, 4 to 4f times in 

 females ; snout obtusely pointed, as long as the postorbital part of 

 the head or less (down to f in full-grow-n males) ; an angular ridge 

 on each side of the postorbital part of the pileus, formed by a keel 

 on the upper temporal shields ; cheeks much swollen in the males ; 

 pileus ly to 2 times as long as broad, uneven and rugose in the 

 adult.* Neck narrower than the head. The hind limb reaches the 

 elbow, the axil, or the shoulder in males, the wrist or the elboAv in 

 females ; foot as long as or a little shorter than the head, rarely a 

 little longer ; toes very feebly compressed. Tail cylindrical, gradually 

 tapering, I^ to slightly over 2 times as long as head and body. 



Nostril pierced between 5 shields ; rostral largely entering the 

 nostril ; suture between the nasals short or very short ; frontonasal 

 as long as broad or a little longer or a little shorter than broad, 

 usually broader than the internarial space, nearly always in contact 

 with the upper postnasal ; prefrontals forming an extensive median 

 suture t ; frontal as long as or shorter than its distance from the end 



* In half -grown specimens the shields are marked with concentric stri», 

 similar to those on the carapace of tortoises, as observed by Lataste in the 

 typical form and by Werner in the A^ar. pater. 



t Separated by a small shield in a male from Cacabelos.
