6. Macroxus morio. 



Fur very abundant, long, soft, black ; head, middle of the back, 

 rump, and outer side of thighs very minutely white-dotted; under- 

 fur brownish, longer ; hairs black to the base, those of the head, 

 rump, and thighs with a minute white tip : cheeks and chin 

 greyish ; throat, inner side of limbs, front edge of thighs, and 

 hinder part of the belly red-washed ; hairs of these parts red to 

 (or nearly to) the base : tail black, slightly white-washed ; hairs 

 black, some of them with an elongated white tip ; hinder part 

 of the base of the ears grey. 



Hab. ? In Zoological Gardens, where it lived several 



years, and remained always of the same colour. B.M. 



The red-brown front of the thighs and the very general punc- 

 tulation of part of the body give it a very peculiar appearance. 



7. Macroxus Boothice. 



Sciurus Boothi(P, Gray, List M. B. M. 139. 



Sc. fuscovariegatus, Schinz, ii. 15. 



Sc. Richardsonii, Gray, Ann. & Mag. Nat. Hist. 1842 (not Bachmann). 



Fur soft, black-grey, minutely punctulated with white ; ear- 

 tuft small, grey ; fore legs, feet, and end of tail black ; underside 

 rather pale, black-grey-punctulated ; hairs of body black, with a 

 grey subterminal band ; hairs of tail black, with a subventral 

 broad grey band and a short grey tip. 



Hab. Honduras (Dyson). Gray's type in B.M. 



The three preceding species are very nearly allied. 



8. Macroxus nigrescens. 



Sciurus nigrescens, Bennett, P. Z. S. 1833, p. 41 ; Aud. & Bach. Q. N. A. 

 iii. 1. 117; S. Baird, M. N. A. 280. 



Black iron-grey; hairs black, with a small white tip; nose 

 and ears pale grey ; chest and belly like back, but with shorter 

 brownish hair; feet black: tail black, grey-varied ; hairs whitish 

 grey at the base, end black. 



Hab. California (Bennett, type in B.M.). 



This specimen is in a bad state. It may be only a small 

 variety of M. vulpinus, or a bad state of M. variegatoides, or 

 distinct. The ears are in a bad state ; but they appear as if they 

 might have been more hairy than those of the usual Macroxi.
