112 CUSCUS MACULATUS. 



right jaw with three small premolars, the hindermost 

 very small and acutely pointed ; left jaw with two small 

 premolars. Irst female; upper jaw: a small and acutely 

 pointed premolar between the canine and the large pre- 

 molar on each side ; loicer jaw : right jaw with two small 

 premolars, left jaw with three small premolars, the hin- 

 dermost being the less developed. 2nd female , upper jaio : 

 a small pointed premolar between canine and large pre- 

 molar , closely crowded to the latter ; loioer jmv : right jaw 

 with four small premolars , the two hindermost excee- 

 dingly minute aad very closely crowded together ; left jaw 

 with three small premolars , the hindermost minute and 

 pointed. The minute size and pointed shape of the super- 

 fluous premolars induce me to believe that they are spu- 

 rious. As the skulls belong to perfectly adult specimens 

 I incline to accept that the apparition of spurious teeth 

 is a peculiarity of advanced age; and this indeed is a very 

 interesting fact as it just is the contrary of what we ge- 

 nerally observe in other groups of Mammals. 



The skeleton presents 13 costales, 6 lurabares, 2 sacra- 

 les and 31 caudales. There are in our collection four ske- 

 letons (adult and young) and about forty skulls belonging 

 to differently aged specimens of the species under consi- 

 deration. For details see page 90.
