On a Collection of Mammals from Central and Northern Queensland. 875 



Height of ear, along its inner margin 28 mm 



Height of ear, along its outer margin 32 „ 



Length of bind foot (to end of middle claw) . . 67 „ 

 Both specimens are young, and in both the milk tooth is still 



present besides the normal 3"^ premolar, while the sutures of the 



skull are rather open. 



The skull. Size of the skull: 



A B 



Length 60 mm — 68 mm 



Breadth 24 „ — 27 „ 



Interorbital space 12 „ — 13,5 „ 



Height above bulla 16,5 „ — 18 „ 



From end of the snout to posterior 



margin of frontalia 46 „ — 55,5 „ 



Length of nasalia 26,5 „ — 30 „ 



Length of dental series in upper jaw .35 „ — 39 „ 



Length of dental series in lower jaw . 33,5 „ — 36,5 „ 



Length of lower jaw 44 „ — 52 „ 



The interorbital space is proportionally wide in these young spe- 

 cimens, about equal to half the width of the skull across the zygo- 

 matic arches, or nearly the same as the base of w * in the upper jaw. 



The nasalia are long, longer than the greatest breadth of the skull 

 across the zygomatic arches. 



The frontalia and parietalia are perfectly smooth, both in 

 front and behind, almost flat, and as yet without a trace of sagit- 

 tal crest. 



Lacrymalia very large; their height the same as the base of 

 the 3 premolars in the upper jaw. 



The zygomatic arch is slender; its height in the centre barely 

 exceeds the breadth of i*. 



Bulla ossea very small, almost round in shape, in length but 

 equal to the base of the 4*'' and half of the 3'^'^ molar. 



Foramina incisiva, long, longer than the foramina palatina ; they 

 extend between the middle (or the back margin) of m * to the centre 

 of p^. 



In the upper jaw of the youngest specimen a trace of an oblong 

 foramen is present in the palate inside p \ whilst this part of the 

 palate in B is imperforate, as in P. macrura.
