The comparative diagnoses above given indicate the average characters 

 of the species, but a series of eight specimens shows a considerable range 

 of variation in color and other details. Aside from the smaller size of the 

 female, 1 have noted no other important sexual differences. The number 

 of white rings on the tail in B. astuta varies from six to nine, the usual 

 number being either seven or eight. They vary in width, being usually 

 narrower than the black ones, sometimes equalling them, while in rare 

 instances the white rings are the wdder. The general color above is 

 gray or brownish-gray, varying in some examples to yellowish -brown, the 

 anterior half of the body being usually purer gray (less suffused with 

 brownish-yellow) than the posterior half. The black terminating the 

 longer hairs varies greatly in amount, but always gives a conspicuous 

 blackish cast to the dorsal surface, while in some the prevailing color, 

 especially along the midvile of the back, is black. In such specimens, the 

 upper surface of the feet is more or less blackish or brownish-black ; the 

 black rings in the tail are broader and the black terminal portion of the 

 tail more extended. A single skin from Oregon * is dark throughout, 

 being as black as the darkest examjjles of B. sumichrasti, and contrasts 

 strongly with the light-colored specimens from Texas and Northeastern 

 *This is the specimen mentioned by Dr. Coues in Amer. Nat., xii, 1878, p. 253.
