ZOOLOGY OF THE VOYAGE OF THE BEAGLE. 
feet rather small, tarsus short ; tail rather shorter than the body, thick at the 
base ; fur long and extremely soft, and silk-like. General colour pale grayish 
brown, with a slight yellow w ash ; the upper part of the head and the 
back dusky brown; under parts of the body very pale yellowish brown, in- 
clining to white ; chin and throat whitish ; feet dirty white ; tail well clothed 
with hairs, which are closely adpressed, brown above, and of a very pale 
brown beneath at the base, darker towards the apex. The hairs of the 
moustaches are numerous, long, rather slender, and of a brownish colour- 
The ears are brown, furnished externally at the base with fur resembling that 
of the body ; the remaining parts (both external and internal) are beset with 
long and extremely slender brown hairs, which project considerably beyond 
the margin of the ear. The ordinary fur on the back is about ten lines in 
length, but thickly interspersed with this fur, are longer hairs which are so 
delicate that they may almost be compared to the spiders’ thread. Both on 
the upper and under side of the body the fur is deep gray at the base. The 
incisors are yellow.

Habitat, Chile, {August.) 
“This animal was caught amongst some thickets in a valley on the flanks of 
the Cordillera, near Aconcagua. On the elevated plain, near the town of Santa 
Rosa, in front of the same part of the Andes, I saw two others, which were crawl- 
ing up an acacia tree, with so much facility, that this practice must be, I should 
think, habitual with them.” — D.
