Lygosoma melanops, spec. nov. PI. VL, figs. 3 and 'ia. 



Two specimens ; between the Everard and Barrow Ranges. 



This species is closely allied to Lygosoma hranchiale, with 

 which it agrees in many respects, but the distance between the 

 end of the snout and the forelimb is contained nearly twice and 

 a-half times in the distance between the axilla and groin instead 

 of once and three-fourths to twice as in L. hranchiale. Body much 

 elongate. The three large vertical spots on each side of the neck 

 in L. hranchiale are absent. 



Colour. — Olive above ; rows of black dots descend from the 

 sides of the head to tlie throat ; alternate scales of the trunk 

 marked with a black spot or short streak ; on the neck-scales the 

 spots are absent, on the tail they are sometimes double. Under- 

 surface pale straw-coloured, with the scales similarly spotted. 



Young, like the adult, but every third or fourth shield having 

 a large white spot. Face, upper and lower lips blackish, Ijut not 

 so dark as in the adult.
