ciliary or frontal band. A whirl is situated on the crown 

 of the head and from this the black hairs are directed hori- 

 zontally forward and especially toward the sides. A small 



but quite conspicuous 

 white perineal patch 

 is present. The termi- 

 nal half of the tail is 

 white, then follows a 



short grizzled grey 

 tract which gradually 



becomes black, 

 sprinkled with white, 

 and finally the bas al 

 part is entirely black. 

 The whole tail is about 

 84 cm. without hair, 

 92 with hair. The ter- 

 minal 44 cm. are wholly 

 white, the foUowing 10 

 cm. grizzled grey, the 

 following 12 cm. black 

 fjnely sprinkled with 

 white and the basal 

 26 cm. entirely black. 

 The hair at the end 

 of the tail is about 

 7 — 8 cm. long, and it 



becomes gradually 

 shorter towards the 

 Imse where it is about 

 2\/2 cm., but, in spite 

 of this difference, there 

 c an hardly be spöken 

 of a real tuft at the 

 end of the tail as the 

 figure (fig. 1) proves. 

 From the base of the 

 tail the length of the 

 fur increases again in a forward direction (see fig. 1) and on 

 the back between the shoulders it reaches a length of about 

 9 to 13 cm., but on the sides just^behind the white shoulder-
