 tortrix. 



* There are many colour phases within this species more or less intermediate between the black 

 eastern form and the light coloured western form. Several of these have been given names but as yet 

 it is not evident that they really constitute true geographic races and hence they are not recognized 

 at present. 



* Bascanion flagellum frenatut Stejneger 1893, not Coluber frenatus of Gravenhorst, 1807.
