D] DBLPHVS CRASS ICAU DATA. 
thirds black, with the exception of a smallish space at the 
cud, which is white. Feet short. 
Inhabits Brazil and Paraguay, and extends southwards as far as 
the Itiver Plata. 
The D. crasaiciiudata is not only remarkable for the great 
thickness of its tail, but differs from all the preceding species 
in having small ears, and these tolerably well clothed with 
small hairs; its toil, moreover, has the part which is usually 
naked, or nearly so, almost covered by small semi-adpressed 
hairs; its feet are very short, and so is its head. The fur 
of the animal, moreover, is remarkable for being composed 
chiefly of somewhat lmrsb hairs, and these pretty closely 
applied to the body, the under fur being rather scanty. In 
colouring it varies considerably. A specimen brought home 
by Mr. Darwin from Maldonado, La Plata, has the upper 
ports of the head and body of a brown*yellow hue, and the 
under parts dirty yellow ; the muzzle, as well as the space 
round the eye, is dusky brown ; the tip of the chin, and also 
the tip of the muzzle, on either side, whitish; the checks 
yellow; the small hairs covering the ears on the outer side 
are brownish, and those on the inner side are yellow, but 
brown towards the outer margin : about one-third of the tail 
is clothed with fur like that on the body : beyond this the 
tail is black, excepting a small portion of about one inch in 
length at the apex, which is white: these black and white 
parts of the tail are clothed with hairs which arc nearly a 
quarter of an inch in length (shorter near the point), and 
are almost sufficiently numerous to hide the scaly skin 
beneath. The hairs on the hack (which are moderately 
long) are grey next the skin, ochreous yellow towards the 
point, and yellowish brown at the point: on the under parts 
of the body they are faintly tinted with grey at the root, and 
of a dirty yellow colour at the point.
