A. Half grown young. Herbert Vale, Febr. 1883 (skin with skull). 



B. YouDg male. Herbert Vale, Febr. 1883 (skin with skull). 



C. Young Female. Herbert Vale, Febr. 1883 (skin with skull). 



D. Herbert Vale, Febr. 1883 (skin with skull). 



E. Herbert Vale, 24. Jan. 1883 (complete skeleton, and incom- 

 plete skin). 



F. Male. Herbert Vale, Febr. 1883 (skin with skull). 



Of these specimens the largest and smallest (A and F) are preserved 

 in the Christiania University Museum (both mounted), as well 

 as the skeleton and the incomplete skin of E. The three other spe- 

 cimens have been given to the British Museum, Museo Civico at Ge- 

 noa, and the Zool. Museum at Copenhagen. 



Of the genus Dendrolagus, in 1884, only three species from New 

 Guinea were known. Two of these, D. ursinus and D. inustus, were 

 described by MtJLLER in 1839 — 44 (over de Zoogdieren van den Indi- 

 schen Archipel, Leid. 1839 — 44) ; the 3"^ , D. dorianus, was described 

 by Ramsay in Jan. 1883 from Mount Astrolabe Range, Port Moresby 

 (in: Proc. Lin. Soc. New South Wales, vol. VIII, p. 17). Through 

 the discovery of D. lumJioltzi^ this genus is proved to exist on the 

 Australian continent, from whence a second species, D. hennettianus, 

 has quite lately been described by de Vis (in: Proc. Lin. Soc. New 

 South Wales, Oct. 27. 1886) from a badly prepared specimen, obtained 

 in the Daintree River District N. Queensland. According to „Nature" 

 (30. Dec. 1886, no. 896, p. 215) de Vis considers it as distinct from 

 D. lumholtzi. 



Natural history. 



In Sept. 1882, Dr. L. on his arrival at Herbert Vale, was in- 

 formed by the natives, that a tree-climbing kangaroo which they called 

 „Boongari", existed in the scrub in the interior of N. Queensland. 

 In Order to obtain this animal, Dr. L. made an expedition into the 

 rocky districts on the Herbert River , but only after several months' 

 work did he succeed in obtaining the first, and subsequently five other 

 individuals, of this species. Two of these were fullgrown, or almost 

 so, the others younger; the smallest is scarcely half grown. 



The largest but one (E) was the first he obtained. Tliis specimen 

 was partly destroyed by a dingo, which ate the head of the prepared 

 skin; fortunately the skeleton had been preserved. The other skins 

 on their arrival at Christiania were in an excellent condition, all with 

 skuUs, and parts of their skeletons.
