 shields (three pairs instead of six) and of scales round the body (24 instead of 28), and 

 the presence of a dark vertebral streak.

Section Parotosaurus *. Habit rather stout ; the distance between the end of the 

 snout and the fore limb once and one-third the distance between axilla and groin. 

 Snout short, obtuse. Lower eyelid scaly. Nostril pierced in a single nasal ; a very 

 small triangular supranasal between the frontonasal, the nasal, and the postnasal, 

 which is single ; frontonasal broader than long, forming a concave suture with the 

 rostral and a convex suture with the preefrontal, which is single (probably an individual 

 anomaly) ; frontal much narrowed posteriorly, as long as frontoparietals and inter- 

 parietal together, in contact with the first supraciliary and the first three supraoculars ; 

 seven supraoculars, first longest, seventh very small; twelve supraciliaries, first largest; 

 frontoparietals and interparietal distinct, the former a little larger than the latter ; 

 parietals forming a suture behind the interparietal ; three pairs of nuchals ; fifth, sixth, 

 and seventh upper labials below the eye. Ear-opening large, oval, smaller than the 

 eye-opening, the tympanum rather deeply sunk ; no auricular lobules. 40 smooth 

 scales round the middle of the body, dorsals largest, laterals smallest. A pair of 

 enlarged presanals. The hind limb reaches the elbow of the adpressed fore limb.
