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 wash ; 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.

" 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.
