132 NOTE ON TRICLINIC FELSPARS. 
detected more than a trace of lime. Meanwhile he was con- 
tinuing his examination of his Charters Towers granite, chemically 
and microscopically, in order to find out whether this triclinic 
felspar, which it contained, was a pure lime felspar or was a lime 
and soda one, and also with which species of felspar it might 
be associated. 
Mr. Clarke’s note concluded with the statement that if the 
occurrence of triclinic felspars containing lime, in the granites at 
Charters Towers, was general, the suggestion that the calcite there 
resulted from the decomposition of lime felspars would be most 
probable, and that the zeolite, too—the subject of his previous 
communication—owed its origin to the same source. 
ON’ A THIRD SPECIES ae 
THE AUSTRALIAN TREE KANGAROO; 
BY 
C. W. DE VIS, M.A. / & 
(Read on 14th October, 1887 ). 
AN accident similar to that which last year brought to light a 
second species of Dendrolagus in Queensland, has quite recently 
delivered up to knowledge a third kind, intermediate in habitat 
but not in features, between D. bennettianus and D. lumholtzi. 
The dogs of some sportsmen hunting in a scrub near Herberton 
encountered and killed an animal which was recognised as a tree 
kangaroo, and the interest excited by the recognition fortunately 
led to the preservation of the skin, which after some time was 
presented in fair condition to the Queensland Museum by D. 
Mowbray, Esq., P.M., of Herberton. Of the specific distinctness 
of the animal represented by this skin from the red shouldered 
species, bennettianus, of the Daintree River, and the smaller 
lumholtzi of the Lower Herbert, there is no room for doubt, and 
under the suggestion of its tawny colour the writer proposes for it 
the name Dendrolagus fulvus.
