fossils was made known. This discovery suggested the advisability 
of further investigations, which having been undertaken under the 
auspices of the Western Australian Museum and the Caves Board, 
resulted in the collection of some thousand bones and the addition 
of several species to the known fauna of the State.

THE NATIVE PORCUPINE or HEDGE-HOG. 
One Monotreme is included in the list of specimens obtained, 
but the only bone yet recognised is the right humerus of a 
Tachyglossus from the older deposit. It is almost perfect, so that its 
comparison with other specimens is not difficult. I he collection 
of Monotremes in the Mammalian Gallery contains several Echidna 
which are all somewhat smaller than the animal which yielded the 
bone now under review. The skeleton of E. aculeata is perfect, and 
gives ample opportunity for studying the typical bones. 
It is seen at once that the Caves’ specimen belongs to a larger 
animal, and that there are a few slight differences which are 
evidently only individual, as Owen’s figure of the humerus of the 
same species, then called E. hystrix (pi. 14 in Phil. Trans., 1884, 
part 1, published in 1885) illustrates a bone which is identical with 
this, though slightly less in its dimensions.
