species, which deserve mention. From the greater length of the 

 muzzle, as already noticed, it mighl be expected that the cranium 

 also would exhibit some corresponding elongation <>f it> anterior 

 part, and accordingly thai is seen to be the case. On comparing 

 the two skulls, that of M. 8eAreibenU, besides being altogether tin- 

 smaller one, has the facial portion more compressed immediately in 

 i'ront of the orbits, and is less dep res s ed . The posterior part 01 the 

 palate also is narrower, bo that the zygomatic arches spring at once 

 outwards from the maxillary hones; whilst in hit-pat is. Where this 

 part of the skull is relatively broader, the sygoma passes off in a 

 backward direction, scarcely making an angle \% i r 1 1 the outer surface 

 of the maxillary hones. 



Another very apparent difference consists in the much greater 

 length and suhstance of the teeth, especially the canines in M. hh>- 

 potis. In this species the upper canines are so long as to pass, when 

 the jaws are closed, almost to the lower margins of the Lower jaw, 

 whilst in M. Sckreibersii their points reach only to ahout the middle 

 of the ramus. It is also deserving of notice, that the singularly 

 formed outer incisors of the lower jaw exhibit the peculiarity already 

 alluded to in a much greater degree in this species than in M. Sckrei- 

 berrii, OT indeed than in any other species appertaining to the genu-.

The specimen-, the dimensions of which arc given in the next 



tahle, formed part of Mr. Gould's Australian collection, and \m ie 



obtained at several localities. They have been selected from a con-
