196 LIZARDS OF THE 



The adpressed hind limb reaches the elbow. No enlarged 

 scale on the heel. Digits slender, with strong sharp claws, 

 the distal phalanges strongly compressed ; subdigital lamellae 

 smooth, 18 under the fourth toe, the fourth and fifth 

 lamellae (reckoned from the claw) being much longer than 

 any of the other lamellae. The tail, regenerated at the tip, 

 a little shorter than head and body. 



Brownish above, with a bluish glossy hue and lighter 

 and darker spots ; below a uniform steelish blue ; tail 

 above with transverse dark bands, separated by lighter 

 interspaces. 



Length from the tip of the snout to the vent: 57 mm. 



Length of the tail (regenerated at the tip): 55 mm. 



One single specimen captured at Long Bloe by Dr. 

 Nieuwenhuis. 



This species is structurally very like the other species 

 of the section Keneuxia, and probably very nearly related 

 to R. Shelford's Lygosoma Vyneri, from which it differs 

 o. a. in the number of scales round the body, the shorter 

 frontal which in our species is in contact with the fron- 

 tonasal and in the coloration. 



I dedicate this beautiful species to Prof. Dr. A. W. 

 Nieuwenhuis, to whom the Leyden Museum is indepted 

 for so many valuable zoological objects. 



* 32. Lygosoma f Vyneri Shelf. 



Another specimen of Lygosoma (section Keneuxia), cap- 

 tured by Dr. Nieuwenhuis on the Upper Mahakkam, differs 

 from the foregoing specimen in the following points: the 

 scales round the body are larger and in 22 series; the 

 praefrontals form a median suture before the frontal; the 

 very small ear-opening is without auricular lobe; the dis- 

 tance between the end of the snout and the fore limb is 

 contained once and two thirds in the distance between 

 axilla and groin ; the adpressed limbs overlap ; the colour 

 of the not very beautifully preserved specimen is a putty 

 grey (perhaps in the living animal olive grey); several scales 

 of the head edged with black; five black stripes over the
