ON CERTAIN GECKOS IN THE QUEENSLAND 



MUSEUM.

 colonial collection has been supplied with examples from Bogan- 

 tungun and Natal Downs. Whether its range extends to the

 species of the genus represented by the example which is submitted 

 for comparison under the name of 



Nephrurus levis, 



distinguishable at a glance from iV. asper by its comparatively 

 smooth lepidosis and expanded tail. 



Description: — Head very large, broader than the neck and body, 

 subtriangular, convex. Snout as long as the diameter of the orbit 

 and shorter than the post-orbital length of the head. Eye large, 

 prominent. Nostril small, horizontally elliptical. Loreal and 

 frontal regions rather concave. Ear orifice a vertical slit half as 

 long as the diameter of the orbit. Body moderately long, slender. 

 Limbs rather short and slender. Basal two-thirds of the tail 

 expanded and flat on the upper surface, the breadth of the expanded 

 portion two-thirds of the length of the same, suddenly contracting 

 on its right side to a tapering peduncle bearing a small symmetrical
