This species ranges over all North America, being limited to the 

 North by its capacity for enduring cold, and extending south to Mex- 

 ico. In its essential characters it is <iuite constant, but it varies in 

 color so as to include several races or subspecies. Of one hundred and 

 two specimens examined, but three have twenty-one rows of scales, the 

 rest having nineteen. Of the same number examined, but six have eight 

 sui)erior labials on both sides, and the additional labial is generally 

 smaller than the others, so as to be an evid( nt abnormality, though 

 sometimes they are regular. In nine specimens the additional labial 

 appears on one side otdy. These abnormalities are distributed as fol- 

 lows :
