HORN EXPEDITION-MAMMALIA. 
21 
So far as I can judge, the tail of the specimen when received by Mr. Krefft 
must have been very similar to that of certain of the least well-preserved 
specimens received by myself from the central district, where the heat is so great 
that, if the animal (as frequently happens of necessity) cannot be placed in spirits 
directly after capture, the skin rots and the fur comes out. How bad the skin of 
Mr. Krefft’s sjiecimen must have been is shown by the fact that one hind-foot now 
measures 18 and the other 24 mm. The nature of the pads cannot unfortunately 
be determined. 
Under the circumstances detailed above—an originally badly-preserved type 
specimen, a drawing which could not in certain respects (as to the tail and 
colouration) have fairly represented the animal, and a description which is not 
only far from complete but is incorrect—there is considerable difficulty in assigning 
with certainty any newly-found specimens to the species in question. 
We have, however, the dimensions given by Mr. Krefft, the corrections in the 
description of the animal as to colour and form of the tail and its crest, which can 
be made after inspection of the type specimen, and the peculiarity noted in the 
dentition by Mr. Krefft. 
A re-description, taking all these points into consideration, would apply so 
closely to the specimens recently obtained from Central Australia, that I have 
thought it better to amend the description as given by Mr. Krefft, and to place 
my specimens in the same species rather than to create a new one for their 
reception. 
The amended description will read as follows:— 
Phascologale cristicauda, Krefft. 
Size large. Form strong. Fur close and soft, mainly composed of the under 
fur. 
The general body colour is mouse-grey tinged with rufous on the back. The 
under surface is white or cream-coloured, and so are the inner and anterior faces 
of the limbs and the upper surfaces of the hands and feet. The under-fur on the 
back is slate-grey at the base and rufous terminally ] on the ventral surface it 
is cream-white terminally. 
The tail is thickly covered in its proximal half on the upper and lateral 
surfaces with coarse, chestnut coloured hairs; on the venti’al aspect the hairs are 
dark brown in colour. About the middle of its length it is covered with coarse 
black hairs, which increase in length disbilly on the upper and under surface until.
