The SKULL of DENDROLAGUS DORIANUS , Ramsay.

(Zoologist to the Australian Museum.) 
[Plates XVIII., XIX.] 
When examining the Tree Kangaroos in the Museum Collections 
for the purposes of my paper on Dendrolagus bennettianus , de Vis,* 
I was somewhat puzzled by a mounted specimen. As however it 
did not throw light upon the species under investigation, it was 
placed aside for future study. 
Having once more taken it in hand, I found that it agreed with 
D. dorianus \ in all described particulars except the non- reversal 
of the hair. A search among the duplicate collections revealed 
two other skins, received along with the specimen mentioned ; 
these presented the aspect of the hair peculiar to D . dorianus. 
Another look at the mounted specimen showed ^that the hair had 
been brushed in the orthodox manner, namely from head to tail. 
These skins were purchased from a Sydney firm of importers in 
December, 1891, the locality given being the Astrolabe Range, 
British New Guinea, whence also the types were obtained. One 
of the skins is headless, but the other contained the skull, from 
which, however, the occipital region had, as usual, been cut for 
the purpose of cleaning the cavity. 
Dr. Ramsay stated J that in the three original specimens, in 
the Macleay Museum, “The teeth and all the bones of the skull 
are in a very bad state, being corroded by the liquid in which the 
skin was preserved.” Baron N. de Miklouho-Maclay § supple- 
mented the original description by a more detailed account of the 
direction of the hair, and bv a notice of the teeth as far as could 
be ascertained from a stuffed specimen. 
These further particulars enabled Mr. Oldfield Thomas || to 
draw up a sufficiently comprehensive synopsis of the cranial
