It has been received by the British Museum from the Peak Downs. The colonial collection has been supplied with examples from Bogan-tungun and Natal Downs. Whether its range extends to the great southern watershed is not as yet in evidence. It may be that its limit in this direction is defined by the presence of a second 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.
