smooth. Digits compressed, with smooth scales beneath, 

 denticulated laterally. Xo femoral pores. Tail long, 

 cylindrical. 



A .single species. 



This genus is to be regarded as an exaggerated form of the repre- 

 sentatives of the section Saurltei in the irenus Scaptira, from which 

 it is evidentlv derived, as Hacmahonia is derived from Sfaptira, s. str. ; 

 but the generic differentiation i» greater than in ilacmahonia, for, in 

 addition to the loss of the femoral pores, the collar has disappeared, 

 and the head has assumed an extraordinary shape.
