Certain Nezv Species of Marsupials. 13 



is terrestrial in habit, burrowing in sandy and stony ground, and 

 is nocturnal and insectivorous. 



It will be noticed that the feet are, in regard to the pads, 

 those of a Sminthopsis rather than a Phascologale. In reality, 

 their dimensions are intermediate between those of the two 

 genera ; and as Phascologale is by no means so exclusively 

 arboreal in habit as is usually supposed, I am inclined to lay less 

 stress upon the presence of five striated pads on the sole of the 

 foot than is usually done. I may here state that, as Mr. Thomas 

 has pointed out, our knowledge of the forms comprised in the 

 genera Phascologale and Sminthopsis is far from complete. 



Mr. Zietz, of the Adelaide Museum, and myself have now a 

 fair collection of the Australian representatives of those genera, 

 and our work upon them has shown us that a revision of the 

 genera, upon which we are now engaged, has become a matter of 

 necessity.
