CUSCUS CELEBKNSIS. 107 



The form of the skull (there are three skulls in our 

 collection) agrees with that of a half-grown Cuscus orien- 

 talis : concave between the orbits , elevated crests or rid- 

 ges bordering this cavity like in that species , but the ca- 

 vity is less deep. The number of the teeth in upper- and 

 lower jaw agrees with that of the same parts in Cuscus 

 ursinus and Cuscus maculatus; the hindmost upper incisor 

 is nearly as high as the canine; the canine and the an- 

 terior upper premolar are separated from each other and 

 from the hindmost incisor and the second premolar by 

 rather wide and nearly equal spaces. The dental formula 



Concluding from the form of the orbital ridges I cannot 

 believe that we possess the fullgrown state of the animal. 

 Our largest specimen agrees in size with a very adult 

 Pseudochirus albertisii.
