“ The nature of the country where this specimen was procured is nearly 
the same as in that part of the Chonos Archipelago, 150 miles to the south, 
where the first was obtained.” D.

Description. — Fur moderate ; ears moderate ; tail shorter than the body ; general 
colour gray washed with yellow ; under parts grayish white. On the upper 
parts and sides of the head and body the hairs are gray, broadly annulated 
with yellow near the apex, and dusky at the apex ; the mixture producing 
a yellowish gray tint, approaching somewhat towards olive : — the hairs on the 
under parts of the body and throat are deep gray at the base, and white at 
the apex ; the hairs of the feet are brownish white. The tail is tolerably well 
clothed with hairs ; those on the upper surface are brown, and those on the 
under are dirty white. The ears are well clothed, both externally and in- 
ternally, with hairs of the same colour as those on the upper parts of the body. 
The hairs of the moustaches are for the most part whitish, and black at the 
base. The upper incisors are pale yellow, and the lower incisors are yellowish 
white.

Subsequent to the description of this species, under the name of M. olivaceus 
in the Zoological Society’s Proceedings, I have imagined that perhaps that name 
might mislead as regards the colouring of the animal ; — it certainly has a slight 
olive hue, but it is not very evident. I have therefore changed the name, and 
substituted that of the author of the “ Naturgeschichte der Saugethiere von Para- 
guay,” &c.
