Besides certain osteological peculiarities which have been pointed 

 out by Cope (premaxillary bones remaining distinct, basal bones well 

 separated, peculiar prootic squamosal crest) this species differs from 

 #. ruber in the larger eyes and the presence of a distinct canthus 

 rostralis. Sixteen or seventeen costal grooves. Purplish grey above, 

 with small, rather indistinct darker marblings ; canthus rostralis 

 paler. Lower surfaces dirty white, with or without brown dots.
