MACEOPOBID^. 



M. agilis from all the localities from whicli these three so-called 

 species have been described. Papuan specimens appear to be 

 somewhat smaller, and to have longer fur and better-defined 

 markings than their North-Australian representatives ; but these 

 characters are not sufficiently well marked to separate the two forms 

 specifically.

Group III. SMALL WALLABIES. 



The members of this group are all small, lightly-built animals, 

 some of them not exceeding a rabbit in size. Their muzzles are 

 invariably naked, and in many of them have a central upward 

 naked projection, the hair growing downwards on each side of it 

 (see for example PI. XL fig. 1). In their skulls the anterior palatine 

 foramina are always very small, and the palatal vacuities very 

 large, usually consisting of a pair of large openings separated by a 

 narrow septum in the middle line. Theii? nasals are, as a rule, 

 much expanded behind, and their interorbital region is generally 

 parallel-sided, without strongly marked interorbital constriction. 

 Their third incisor is smaller in proportion than in the last group, 

 and has always one single well-marked notch, usually close to the 

 posterior end of the tooth. , 



The range of this group extends much further into the tropics 

 than that of either of the other two, one of its members being the 

 anciently known " PUander " or Aru-Island Wallaby (M. hruni), 

 and another (M. broumi) extending through New Guinea into the 

 New Britain group of islands.
