These specimens show the differences between A. jiersica and A. crural is, Blanford, to 

 be less important than was hitherto believed. The following notes are taken from the 

 specimens collected by Dr. Aitchison : — 



The fore limb being stretched forwards, the wrist reaches the tip of tlie snout, or lialf- 

 way between the latter point and the eye ; the hind limb reaches the ear, or halfway 

 between the ear and the eye, or (in a young male) as far as the eye. Rostral twice or 

 not twice as broad as high, completely divided into two, entering or not entering the 

 nostril ; 12 to 14 upper and 9 to 12 lower labials ; mental not twice as l)road as long, 

 sometimes with a shield on each side between it and tlie second infralabial. The enlarged 

 dorsal tubercles sometimes keeled and subtrihedral. Numerous enlarged tubercles on 

 the hind limbs. Male without or with two praeanal pores.
