 legs, a bar across the buttocks joining the thighs greyish-white ; 

 face, legs, and tail black ; a ring encircling the body like

 well-marked variety of the same species, and may easily be 

 recognised by the ears, ruff and whole upper surface of body 

 bting dark rusty-red, with the outer surface of thighs and legs 

 white; or, the ears, ruff and whole upper surface (except a 

 white patch on the back of the neck) may be dark brown, with 

 a white garter on each ankle ; otherwise it may be entirely 

 black. It is this variety which we have figured on Plate VII.
