between one and another seem to be so complete that I have 

 failed to recognize any division of more than subspecific rank. 

 At first it appeared that at least the dark forms with red feet 

 {eborivorus) might be separated specifically from the straw, 

 coloured ones with yellow feet {Stangeri), but the animal I 

 have named nigerice is really practically as yellow as 

 Stcuigeri, while it has the red feet of eborivorus and the white 

 neck-patches of Temviinckii. A^ain, an Eastern Congo 

 specimen has a yellow Stangeri back with red eborivorus feet, 

 but is without white neck-patches. As to distribution, there 

 is as yet no evidence that both Stangeri and eborivorus forms 

 occur in any one district, though the ranges of the two types 

 largely overlap. 



The recognition of Wilsoni as a Funisciurus and of 

 Stangeri as a true Sciurus is due to Mr. de VVinton, who 

 wrote some notes on the group in 1898 *. 



The following are descriptions of the new subspecies : — 



Sciurus Stangeri loandce. 



Size and general characters quite as in true Stangeri^ 

 though the yellow of the hinder back is raiher more vivid. 

 Head, instead of turning hoary grey on the crown, simply 

 becoming paler and more whitish yellow than the back ; a 

 dull yoUowish patch behind each ear, and the ears themselves 

 yellow rather than brown. Cheeks whitish or greyish white. 

 Line edging body-hairs along sides of belly well-marked, 

 white. Feet, especially the anterior, more strongly sutfused 

 with yellow above. Other characters as in true Stangeri. 



Dimensions of the type (measured in the flesh) : — 



Head and body 285 mm. ; tail 380 ; hind foot 66 ; ear 21. 



Skull: greatest length 68; condylo-basilar length 57; 

 length of upper tooth-series 11*5. 



Ilab. Northern Angola. Type from Cinhoca. 



Type. Adult male. B.M. no. 4. 4. 9. 42. Original num- 

 ber 199. Collected 12th December, 1903, by Dr. W. J. 

 Ansorge. 



This is the only form of the whole series which has not got 

 the characteristic contrasted grey head which caused Tem- 

 niinck to give the preoccupied name of caniceps to the Gold- 

 Coast animal. 



Sciurus Stangeri nigerice.
