2. AcANTHOSAURA HAiNANENSis, sp. n. (Plate LXVI. fig. 2.) 



Snout as long as the diameter of the orbit ; canthus rostralis 

 and supraciliary edge angular ; tympanum smaller than the eye- 

 opening ; upper head-scales keeled, larger on the supraorbital 

 region and in the middle of the forehead ; a spine, measuring one 

 third the diameter of the orbit, terminates the supraciliary edge ; 

 11 or 12 upper and as many lower labials; gular scales strongly 

 keeled, smaller than the ventrals. An oblique fold on each side of 

 the neck, in front of the shoulder ; a spine, measuring two fifths 

 the diameter of the orbit, on each side of the nape above the 

 tympanum. Nuchal crest not continuous with the doi'sal, com- 

 posed of rather slender compressed spines, the longest of which 

 measure nearly half the diameter of the orbit. Dorsal crest low, 

 composed of triangular compressed scales pointing backwards, 

 subequal in size throughout the back. Dorsal scales very small, 

 intermixed with irregularly scattered, enlai-ged, rhomboidal, more 

 or less strongly keeled ones ; ventral scales about as large as the 

 enlarged dorsals, strongly keeled. Fore limb and tibia above with 

 subequal keeled scales, femur with unequal ones ; fourth finger 

 a little longer than third ; the adpressed hind limb reaches the eye. 

 Tail feebly compressed, covered with uniform strongly keeled scales, 

 which are larger on the lower surface. Olive-brown above, with 

 rather indistinct wavy darker cross-bars ; a dark, light-edged rhom- 

 boidal marking between the shoulders, produced forwards along the 

 base of the nuchal crest ; antehumeral fold blackish ; limbs and 

 tail with light transverse bars.
