[Received January 16, 1875.] 
(Plates VII.-IX.) 
During the time that H.MLS. ‘ Basilisk’ was cruising in the region 
of the south-east of New Guinea one of the sailors acquired a 
specimen of a small Kangaroo, which Signor L. M. D’Albertis, 
C.M.Z.S., obtained from him at Sydney. In a letter addressed to 
Mr. Sclater, dated Sydney, N.S. W., December 1, 1873, Signor 
D’Albertis described this specimen, under the name of Hulmaturus 
luctuosus, as follows *:—‘‘ Length from the nose to the occiput 43 
inches; length of the ears 1? inch; length of the thigh 52 inches ; 
length of the tarsus, including the nail, 43 inches; length of the tail 
113 inches. Total length, from the nose to the tip of the tail, 2 feet 
5 inches. Its weight is 77 pounds. 
“The fur is short, its.general colour dark ashy brown with a 
silvery tinge, white at the roots; chin, throat, and chest white, with 
two horizontal ashy stripes under the pouch; on the top of the 
head a silvery whitish spot; the thighs more grey ; feet dark, almost 
black ; the arm white inside ; the hand black. The tail moderately 
strong, of a similar colour to the body, but white and bare of hairs 
for about an inch at the extremity. The lips are barely covered 
with fur; the eyelids are puffed, almost naked, and provided with 
eyelashes so fine as not to be readily seen at first sight.” 
Hab. ‘‘8.E. of New Guinea.” 
On April 17, 1874, this Kangaroo was deposited by Signor D’ Al- 
bertis in the Society’s Gardens; and at the Meeting for Scientific 
Business on May 5th following, Mr. Sclater, in reporting on the 
additions to the Society’s Menagerie +, exhibited a drawing of it, and 
referred to it as “the typical example of Halmaturus luctuosus of 
D’Albertis.” It is this specimen, a female, which forms the 
subject of the present communication. It died, Nov. 24, 1874, 
with congested lungs, after a severe frost, the first of the commencing 
winter. 
An examination of the dead body, and especially of the mouth, 
which it was impossible to observe in the living animal, made it 
evident that the species could not be rightly included inj the genus 
Macropus or Halmaturus. Further comparison made it clear 
that it was intimately related to the genus Dendrolagus, and also to 
the species described in Waterhouse’s ‘Mammalia’t as Macropus 
brunit.
