Palate-ridges (fig. 13) are seven in number, of which five interdental, the hindmost 

 very feeble and inconspicuous; further détails may be studied from the very accurate drawing, 

 again quite différent from the palate-ridges in ail other Pogonomys-s.Qe.cies hitherto known. 



Comparing the above description with those of the long-taMeà Pogonomj/s-species, we 

 see that our species is quite différent in colouring, besides its belonging to the s/iort-tailed 

 forms, as our young spécimens prove, and that therefore the animal hitherto was undescribed.

Skull of an adult maie spécimen, Okaba, October 1. 1907, without lower jaws, without 

 ncisors and canines, generally in a very poor condition, and a young spécimen (in alcohol). 



MARSUPIALIA.

N°. 47. Adult female (in alcohol), Van Weel's Camp, June 3. 1907, 



N°. 125. Adult maie (flat skin with skull), Alkmaar (300 meters), August 13. 1907, 



N°. 126. Adult female (flat skin with skull), Alkmaar, August 14. 1907, 



N°. 127. Young maie (flat skin with skull), Alkmaar, August 15. 1907. 



In wet condition the adult female presented the following measurements in mm. : 



head and body 615 



ta il 3 2 5 



hind foot with claw 145 



ear 49X33 



eye to nose 60 



eye to ear 38 



This female has the ear broadly rounded off above, outer margin nearly straight, then 

 convex. Tail near its base elliptical in cross-section, for the rest nearly circled; at the base 

 it measures 105 mm. in circumference.

1) By a slip of the pen I said that in the skull of Dorcopsis Hageni (Nova Guinea. Vol. V, Zoologie, p. 373) 

 the condylo-basilar length was 105 mm. and the condylo-basal length loi ; it is évident that the meaning was just the 

 reverse, viz: the condylo-basal length is 105 mm., and the condylo-basilar length loi mm.
