As these are the only remains found the species must liave been 

 very rare in the district at the time of the deposit. 



At present the species is found in the district and may be 

 regarded as not infrequent, though I am led to believe that 50 years 

 ago it was very abundant, the present scarcity being due 

 apparently to the havoc made amongst them by domestic cats. 



Pal^opetaurus elegans, Broom. 



(PL VII. fig. 3). 



This small Petaurus-like Marsupial I recently described* from 

 some jaws and a well preserved specimen with the maxillary 

 teeth. Since then I have found besides numerous jaws a 

 moderately good portion of the skull (Plate , fig. 3) and a 

 number of other fragments. The frontal bones differ from those 

 of Petaurus, and agree apparently with Gymnobelideus in being 

 without supraorbital ridges; and the hinder part of the frontals 

 is considerably broader and flatter proportionally than in 

 Petaurus. The snout though narrow appears somewhat broader 

 than in Gi/in)iobeU,deus judging by the figure. In one of the type 

 specimens the upper p^ was found to be single-rooted, or rather 

 its two roots were united together. This, too, appears to be rather 

 variable as in two other specimens one is found with the roots close 

 together but distinct, while the other has the roots somewhat 

 apart. In all the observed specimens, however, p^ is double 

 rooted. 



Dromicia nana, Desm. 



One of the most interesting discoveries is that of Dromicia 

 7iana, of which I have found a large number of both lower and 

 upper jaws. There can thus be little doubt but that in later 

 Tertiary times Dromicia iiaaa was very common in New South
