oil sides, limbs, and feet, and other cliai'acters, but distin- 

 guished as follows '. — General colour above, especially on 

 head, slightly darker. Light lateral lines better marked, 

 cream-coloured. Area behind ears with a much more con- 

 spicuous white patch, that of mandingu being small and 

 little obvious. Under surface white, not shar|)ly defined 

 laterally, the hairs light to their bases ; iu mandingo all the 

 hairs have slaty bases. 



No external measurements available.

Type. Adult male. B.M. no. 2. 11. 10. 11. Collected 

 by Mr. A. J. Braham, 



This squirrel is curiously more like tlie Gambiau mandingo 

 than the other Nigerian members of the group. It may, 

 however, be readily distinguished by the white instead of 

 grey-based hairs of its under surface. 



Funisciurus leucostigma talboti, subsp. n. 



General appearance as in true leucostigma, though with 

 many differences in detail. Back of the same grizzled oliva- 

 ceous tone, but light bands white instead of buffy or ochra- 

 ceous, and succeeded externally by a line less distinctly 

 blackish. Rufous of head and limbs slightly duller than in 

 leucostigma, and that of flanks very much duller, approaching 

 tawny olive of Ridgway, though darker. On the under 

 surl'ace the colour of the flanks encroaches on each side, 

 nearly meeting in the middle line of the belly, and at the 

 same time becoming more ochraceous , chin, chest, and 

 groins dull whitish, the majority of the hairs with slaty 

 bases ; in leucostigma the under surface is completely white, 

 the hairs white to their bases. Tail with its median area 

 below of the same dull grizzled rufous that is found in the 

 Sierra Leone form, leonis *, quite different from the bright 

 uniform rufous occurring in leucostigma. 



Skull of about the same size as in leucostigma ; upper 

 profde of brain-case much bowed. 



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



Head and body 185 mm. j tail 150 f; hind foot 44; ear 15. 



Skull : greatest length 48 ; condylo-basal length 4.2 ; 

 greatest breadth 26*8 ; Iront of jy* to back oVin' 8*4.

 t The tail is now 180 mm. iu length, and tlie number above given is 

 perhaps a lajjstis calami.
