OF NEW SOUTH WALES. 33 



Description of a new genus and Species of Eat Kangaroo, allied 

 to the genus Hypsiprymnus, proposed to be called Hypsi- 

 prymnodon moschatus, byE. Pierson Ramsay, F.L.S., CM. Z.S., 

 Curator of the Australian Museum, Sydney. 



I had provisionally placed this animal, on account of its dental 

 formula and the formation of its premolai-s, in the genus Hypsi- 

 prymnus, from which, however, it must be separated, as will be 

 seen from the following remarks ; and on account of these peculiari- 

 ties and differences, I have formed for its reception the new genus 

 I now propose to call Hypsiprymnodon, which may be thus charac- 

 terised : — 



Skull very similar to that, of Hypsiprymnus, but more elongated 

 anteriorly, the distance between the premolars and canines, and 

 between the canines and third incisor, comparatively greater than 

 in either Hypsiprymnus or Betongia ; angular process of mandible 

 broad and rounded, the ascending of ramus short, rather wide, not 

 much longer than the condyloid, which is also comparatively 

 short ; the posterior palatine openings confluent, narrow, acute 

 anteriorly, the anterior margins meeting the exterior-lateral at an 

 acute angle, curved outwards and reaching to opposite the posterior 

 margin of the premolars ; anterior palatine openings linear, some- 

 what oval, twisted, acute posteriorly, (the posterior and basal 

 portions of the skull have been cut away). 



The teeth are identical with those of Betongia and Hypsiprymnus, 

 with these differences ; the premolar narrower and placed more 

 obliquely in the jaws — the canines small and feeble ; incisors long, 

 narrow, rounded externally. The fore feet of five toes, regular, 

 hand-like, last two joints of the toes scaly, the nails small and
