and meeting that of the head, which is directed backward, forms 

 a ridge between the ears and down the sides of the cheeks, and 

 is similarly directed on the limbs, the hair on the legs and arms 

 being directed forward, as is usual." (1 ) 



Having had the opportunity, through the kindness of Mr. 

 Wm. Macleay, of closely examining in his museum three 

 specimens of Dendrolagus Borianus (adult $ and 9 and a 

 young (J) (2), it appears to me that some additional remarks 

 about this most interesting animal to the description cf Mr. 

 Ramsay will not be out of place. 



The principal external peculiarity of the same is, without 

 doubt, the remarkable direction of the hair on its back, a fair 

 idea of which may be gained by the inspection of fig. 2 (pi. 71), 

 representing Dendrolagus Dorianus in profile, with the direction 

 of the hair marked with small darts. The converging point 

 (marked with * on fig. 2] of the lines forming the boundary of 

 the hair directed forward and the hair directed backward, is 

 situated in the middle line, near the base of the tail (565 mm., 

 or about 21-1 in. behind this occiput). From this point the lines 

 run forward and outward (the animal examined in the position 

 represented on fig. 2) to the sides of the knee-joints. From this 

 dividing line the hair of the back is directed forward, while on 

 the sides of the body the direction of the hair is gradually 

 bending towards the ventral middle line. The hair of the head 

 directed normally backward in meeting the hair of the neck 

 (directed forwards) forms between the ears a hair-ridge, which 

 is less marked than in Dorcopsis, which extends from the ears to 

 the front along the lower edge of the under-jaw. On the ventral 

 surface of the neck, beginning a little above the episternum, the 

 hair is directed upwards, whilst two narrow bands, with the hair

 for his description of the species — Dendrolagus Dorianus— and so far as I 

 know, the only specimens of this species brought, until now, from New 

 Guinea.
