REVISION OF THE KING SNAKES. 139 



Of the present known range of calligaster, the northeast has points 

 distinctly against its consideration as the required center, namely, 

 (1) this portion is north of the southern limit of glaciers, (2) the 

 pattern appears to he degenerate (indistinct) here, (3) the number of 

 scale rows is somewhat diminished in the northeast, (4) the infra- 

 labials are here less often 10. We must therefore look south of the 

 Missouri Eiver and west of the Mississippi for the center of the 

 group. Of this region we know very little of the situation outside 

 of Kansas, and this is too far north to be a center of reptilian preserva- 

 tion and radiation. 



We are forced therefore to look to the "Southwest" — perhaps 

 Texas or northern Mexico — for the center of dispersal of this group, 

 and to await fuller information before being more specific.
