200 LIZARDS OF THE 



about one third of the visible part of the scale. On the 

 nuchal scales there are three swollen bands, one in the 

 middle and two on the flanks, separated by two grooves. 



Upper head-shields uneven, rugose. Snout long, pointed. 

 A single frontonasal, much longer than broiad, in contact 

 with the rostral as well as with the frontal. Frontal as 

 long as frontoparietals, interparietal and parietals together. 

 The distance from the posterior point of the frontal to 

 the tip of the snout once and a half the distance from the 

 posterior part of the frontal to the posterior part of the 

 suture between the parietals. Five supraoculars, first longest, 

 fifth very small ; six supraciliaries anterior to the fourth 

 supraocular, the seventh in contact with it. Frontoparietals 

 smaller than the interparietal, behind which the parietals 

 form a suture. Fifth upper labial largest, in contact with 

 the eye. A very large azygos postmental, followed 

 by two pairs of large postmentals, both in contact with 

 each other over the whole length. Third pair of submentals 

 much smaller, separated by four scales, three of which are 

 only a little smaller than the submentals themselves. A 

 single large plate covers the praeanal region. The adpressed 

 hind limb reaches between the wrist and the elbow. Sub- 

 digital lamellae smooth. 



Though the foregoing specimen from the river Howong 

 forms the passage between this specimen and the typical 

 Tropidophorus Beccarii with regard to the disposition of 

 the praefrontals, the submentals and the size of the frontal, 

 still I see so many differences between our Kajan- and our 

 Howong-specimen, especially in the form of the head-shields 

 and of the scales on the back, that I think I am justified 

 in describing this Kajan-specimen as the type of a new 

 species.

Three specimens: one semi-adult, measuring 60 mm. from 

 snout to vent and with a total length of 180 mm., and 

 two young ones, with a total length of 100 mm., all collected
