298 Mr. 0. Thomas on 



Size and general coloin- as in tlie darker forms of F. palli- 

 otus, the dorsal colour closely matching that of F, p. ornatus, 

 ■vviiile the belly is a little darker and richer than in any of 

 them, nearly matching the maroon-red of the tail of F. p. or- 

 natus. Muzzle, forearms, inner sides of hind limbs, and end 

 of tail-hairs all of the same rich maroon-red ; but the upper 

 surface of the hands and feet, instead of being also red, are 

 deep glossy black without trace of red, the change at the 

 wrists and ankles being apparently abrupt, though there are 

 micioscopic red tips to some of the hairs on the metapodials. 



Skull and dentition as usual, except that the top of the 

 muzzle is flattir, less bowed downwards, and the molars 

 appear to be rather narrower than in the mainland subsiiecies. 



Dimensions of the type : — 



Hind foot, s. u,, (c.) 49 mm. 



Skull : greatest length 51 ; length of molar series exclusive 

 of/ 8-8. 



Jlah. Zanzibar Island. 



Type. Adult male. B.M. no. 6. 6.5. 21. Collected and 

 presented by J. T. Last, Esq. 



This squirrel is so abruptly different from any of the forms 

 of F. j^aiiicitns by its black instead of red hands and feet that 

 ii'any naturalists would think a binomial should be used for 

 it ; but it is so essentially a member of the palliatus group 

 that I prefer to regard it as a subspecies, especially as faint 

 indications of red may be found on its feet and also slight 

 traces of black on those of F. p. sua/ielicus, its nearest 

 relative. 



In Mr. Oscar Neumann's account * of the subspecies of 

 F. palliatus he records F. p. suaheJicus from Zanzibar ; but if 

 his specimens were reall}' obtained in the island lie must have 

 overlooked the very material difference in the coloration of the 

 feet. 



Mus BrocTcmaniy sp. n. 



A medium-sized pale grey species, with a very long 

 pencilled tail. 



Size and general proportions very much as in M. Ver- 

 rtaitxi of the Cape. Fur of medium length j the ordinary 

 liaiis of the back about 9 mm. in length, the isolated longer 

 hairs 12 mm. General colour above pale buffy grey, })aler 

 than Eidgway^s " drab-grey," the light rings to the iiairs
