This species comes near to P. obesula, being slightly stiffer 

 in the hair than that species, but much less stiff than P. 

 Cockerellii, from New Ireland, which has the greater part of the 

 hair black, and sufficiently spiny to penetrate the skin if roughly 

 handled, moreover in P. Cockerellii, the space between the last 

 incisor and canine is fully twice as wide as it is in the present 

 species.
