Very nearly allied to P. theohaldi, but distinguished in the 

 following characters : — The toes are less distinctly denticulated 

 laterally, the middle ones being almost deprived of any such den- 

 ticulation ; all the scales, and especially those on the upper surface 

 of the head, smaller ; scales on the limbs keeled ; tail longer, nearly 

 twice as long as the distance from gular fold to vent, tapering to a 

 fine point. Light grey above, dotted with darker ; two series of 

 small dark spots along the back ; end of tail black inferiorly ; lower 

 surfaces white, with a faint blackish line along the middle of the 

 belly. 



Total length 112 millira.

Phrynocephalus versicolor, Strauch, Voy. Przewahki, Hept. p. 18, 

 pi. iii. hg. 2. 



Forehead slightly convex and sloping, with enlarged convex 

 scales ; occipital scales enlarged ; median supraorbitals smaller than 

 median dorsals ; nostril directed forwards and slightly upwards ; 

 nasal separated from its fellow by three longitudinal series of scales. 

 Dorsal scales homogeneous, granular on the sides, enlarged, flat, 

 smooth, and imbricate on the vertebral region. Gular and abdominal 

 scales smooth, pectorals very slightly keeled. Third and fourth toes 

 on both sides with a strong fringe of acute lobules. Tibia as long 

 as the skull. Tail roundish, tapering to a rather fine point, covered 

 with keeled scales : its length equals once and a third to once and 

 three fourths the distance from gular fold to vent. Greyish above, 

 spotted and vermiculated with darker ; limbs and tail with dark 

 cross bars, which form three or four complete annuli, black inferiorily, 

 at the end of the latter ; lower surfaces white.
