The lower jaw is very slender, and the pars articularis directed 

 obliquely backwards, whilst in P. macrura and P. obesula the Pro- 

 cessus coronoideus is vertical. 



The teeth. The dentition is normal in both specimens, but, as 

 above meutioned, the milk teeth are present besides the permanent 

 premolars. 



i f , c A, p f , m f (48). 



In the Upper jaw the central incisors are somewhat smaller than 

 the others, and rather close; i ^ which is isolated, and has, like in 

 the other species, the shape of a premolar, is separated from i ^ and 

 c by an interval about double as large as its own base. 



The canine is as yet not very long, in the youngest specimen 

 barely higher than the nearest premolars; it is separated from p^ 

 by a Space about equal to that of its own base, 



The 3"^ premolar is not fully developed in either specimen, The 

 small molarshaped milk tooth which is still present posteriorly at 

 the outer margin of ^^, is extremely small, cylindrical, smaller than 

 ^^ In the youngest specimen, ^9^ is wanting in the right upper jaw, 

 and does not appear ever to have been present, 



The last molar is flattened, triangulär, its back angle being 

 pointed, as in P. macrura, but is much shorter than in that species. 

 m 2 and m ^ appear to be equal in size. 



In the lower jaw the milk-tooth is present in both specimens ; in 

 the youngest specimen only the tip of the permanent ^ ^ is visible 

 above the alveolar margin.

M. giganteus is still common in Central Queensland, and can in 

 some districts be met with in enormous numbers, for instance on the 

 Peak Downs, 200 miles NW. of Rockhampton. It appears to be some- 

 what less numerous in Northern Queensland.
