ish, with irregular brown bands which converge between and 

 behind the orbits; others diverge on the flanks, beginning at 

 the orbits; one from same point to hip, and one to can thus 

 rostralis. There is a confluence of dorsal bands near the 

 sacrum. A light band on outer face of tarsus and toe." * 



In life examples of Type A present the appearance of 

 plainly colored, unmarked animals. The markings in the 

 third type, however, are very conspicuous in both living and 

 preserved specimens. In my report on the reptiles of McLen- 

 nan County,! Texas, through a careless reading of the manu- 

 script, I am made to say that the majority of the cross-barred 

 examples are males, when 1 intended to say females. During 

 the months of April and May of this year I collected 87 adult 

 examples of this species. Forty-two of these were females, 

 all cross-barred. Of the forty-five males, thirty-eight were of 

 Type A, the others were of Type B.
