precisely annlogouB case in the Agamidee^ in which I feU loth to 
create an arli(icial genus, 1 have acted in tlie mm& \thy in the pre- 
sent instance. The Uromastia: prineep* recently described by me 
(P. Z. S, 1S80, p. 445) has an abnormallv flattened spinous tail of 
extraordinury appefirfince^ bat somewhat like the tail of Jtpinosm, 
It consequently differs from tlie other species of Uromasfir with 
long verticillated tails, in just tbe satne way as //- apinoms differi 
from the present species. In other respects these two species are 
so similar that it is diftictiU to draw up a complete specific diagnosis 
of tbe new one. There are, however, fewer labial shields ; and the 
limbs are considerably longer, the hind ones reacbing to the front of 
the ear, while in H, spitio^us they reach only to the shoulder.
