DIDKLPirVS MACUOTARSDS, ETC. 
Didelphyt inacrolarrtut, 
Dr. Wagner states, resembles the D. marina , excepting in 
liaving the ears much larger, its tail entirely naked, and of a 
deep reddish ash colour, and its feet stout and elongated. 
The second species— 
Didelphyt microtarsus, 
Also resembles D. marina , hut has the ears much larger, 
the tail of a deep reddish grey, and with minute hairs on the 
under side, and the taisi short and slender. 
I will here introduce some other species of Opossums 
described hv the same author in the work mentioned. The 
species in question were collected by Dr. Natterer during his 
long sojourn in Brazil ; some of them arc stated to be desti¬ 
tute of a pouch, and therefore belong to the present section, 
and it is highly probable that the females of die remainder 
are also pouchless. The shortness of the tail in die following 
four species would seem to indicate that they are very nearly 
allied to the Didelphyn tricolor, and the D. brachyara .
