6. Macrozus 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 Boothe. 
Sciurus Boothie, Gray, List M. B. M. 139. 
Sc. fuscovariegatus, Schinz, u. 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. Macrozxus nigrescens. 
Sciurus nigrescens, Bennett, P. Z. S. 1833, p.41; Aud. & Bach. Q. N. A. 
iii. t.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 ina bad state; but they appear as if they ' 
might have been more hairy than theme of the usual Macrozi.
