Nearly related to G. lorim Blgr. (Ann. Mus. Genova, [2] xviii. 1898, p. 695, pi. vi.) ; 

 distinguished chiefly by the finer granules, the more prominent tubercles, especially on 

 the lateral fold, the interrupted series of prteanal and femoral pores, and the longer 

 tail with transversely enlarged scales inferiorly.
