Show MAMMALIA. 51 "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."

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 siues of the head and body the bairs 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 internally, 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.

Lines. 0 11 St1 bsequent 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 l1ave therefore changed the name, and substituted that of the author of the "Naturgeschichte der Saugethiere von Paraguay," &c. |
