252 REPTILES FROM NEW GUINEA. 



12. Lygosoma fiiscum D. & B. 



Four specimens; in one of them the frontoparietal is 

 fused with the small interparietal shield. 

 1 3. Lygosoma caUisiictum Ptrs, var. (Plate 6, figs. 2 and 2a). 



Three specimens , very much agreeing vrith one another, 

 but showing some small differences. One of them (the figured 

 one) is somewhat slenderer than both the others and its 

 frontal more elongate. As to the coloration , the figured 

 one and one of the others are of a metallic hue, bluish 

 green in the first one, bronze-coloured in the latter; the 

 third specimen is brown without metallic hue. The former 

 two have a somewhat lighter line running along the middle 

 of the head and nape. In all the specimens the scales have 

 a darker centre encircled by a lighter border. 



These specimens very much agree with L. callistictum 

 Ptrs. but differ from it in having 4 instead of 5 upper 

 labials before the large subocular , moreover they have no 

 bicarinate dorsal scales although the scales show an in- 

 dication of stripes. I give here a description with a figure 

 of this beautiful species. 



Habit lacertiform , the distance between the end of the 

 snout and the forelimb is contained one and a third in 

 the distance between axilla and groin. Snout rather long, 

 pointed. Lower eyelid with an undivided transparent disk. 

 Supranasals very small , widely separated. Frontonasal 

 broader than long ,. forming a suture with the rostral and 

 with the frontal. Frontal longer than broad , in contact 

 with the two anterior supraoculars. Four supraoculars 

 followed by a small shield that may be regarded either as 

 the fifth supraocular or as the last supraciliary shield. 

 Eight to nine supraciliaries, the first one ') in contact with 

 the first supraocular, second loreal and praefroutal. No 

 interparietal ; parietals forming a suture behind the large 

 frontoparietal ; a pair of nuchals and a pair of temporals 

 border the parietals. Four upper labials before the large 



1) In our figure this shield is somewhat too large.
