“‘Trides yellowish brown. Native name ‘ Nyani.’”—P. R. 
Size and length of fur very much as in P. thoth, Og., to which 
the species seems to be most nearly allied, but the hairs are softer 
to the touch, entirely different in colour, and unannulated 
throughout. General colour hoary grey, not very unlike that of 
such specimens of Didelphys marsupialis as have white-tipped 
bristle-hairs. Throughout, on the upper surface, there are two 
sorts of hairs, the shorter about 3-4 inches in length, and the 
longer about 7 inches; both have black tips about ? to 1 inch 
long, while their remainder is dirty white. In a general view the 
black tips of the shorter hairs show clearly against their white 
bases, but those of the longer hairs do not show at all, so that 
these latter look wholly white. The general hoary colour 
obtained by this mixture of black and white extends all over the 
upper surface, including the head, along the outer sides of the 
limbs to the metapodials, and to the end of the tail, which is, 
however, rather blacker proximally and whiter terminally than the 
rest of the body. Tip of tail untufted. Below, on cheeks, chin, 
and belly, and on the inner sides of the limbs the black tips 
disappear, the fur is then entirely dirty white. The fingers and 
toes are also nearly unmixed white. 
Skull very closely resembling that of P. thoth in size and 
general characters, but the muzzle is very decidedly shorter. 
Thus, while the distance from the orbit to the occiput is almost 
identical in the two, that from the orbit to the gnathion is very 
materially shorter in the new form. The muzzle is also more 
tapering and less parallel-sided anteriorly. The nasals are less 
flattened, and are more clearly visible in a lateral view of the 
skull, Below, the palate is shorter, the tooth-rows are more 
bowed in anteriorly, and the pterygoid fossz are broader. 
In the lower jaw the pit below p2&m.! is very much shallower, 
indeed scarcely noticeable, and the chin is much more developed, 
probably because of the shortening of the palate and consequent 
vertical position of the lower incisors and canines.
