MAMMALIA. 615 



upper middle incisors long, produced beyond the small lateral inci- 

 sors. Ears oblong, rounded, small. Claws of fore feet compressed, 

 curved, with the three middle ones longer, the outer and inner very 

 small. Posterior feet far surpassing the anterior. Tail shorter 

 than body, slender. (Nasal bones acuminate at the extremity, pro- 

 duced beyond the upper jaw.) 



Sp. Hypsiprymnus murinus Illig., Macropiis minor Shaw, White Neio 

 South Wales, PI. 60, p. 286, Watebh. Natur. Library, T. 16; Potoroo or 

 Kangaroo Rat; New South Wales (the skeleton figured in Pander m, 

 D'Alton 1. 1. Tab. 3). The species of this genus are small. Some have 

 long hairs at the end of the tail with which they can grasp grass and plants 

 and drag them to their nest, as Hypsiprymnus cuniculus OsiLBY, Gould 

 Macr. II. PI. 14. 



Dorcopsis Sal. Muell. and Schl. Two upper middle incisors 

 longer than lateral. Ears oval, narrow, moderate. Head long, 

 protracted, produced beyond the mouth. Claws of fore toes strong, 

 somewhat flat. Hind feet far surpassing the fore feet. Tail 

 shorter than body, rather thick, ringed with scales towards the 

 apex, naked. 



Sp. Dorcopsis Brunii {Hijpsqwymnus previously) Sal. Mueller and Schleq. 

 Natuurh. Vcrh. over Nederl. Overz. Bezittingen, Mamm. PI. 11; New 

 Guinea and perhaps the Aroe Islands, if this species be the same as the 

 Pilander of De Brutn, DidelpMs Brunii Gm. This animal is much larger 

 than the Potoroos and resembles the smaller species of Kangaroos, with 

 which, however, they are improperly united by Waterhouse. A figure of 

 the skull has been published already by Pallas, after a drawing of 

 P. Camper. Act. Acad. Petropol. 1777, Tab. ix. fig. iv. 



Dendrologus Sal. Muell. Two upper middle incisors scarcely 

 longer than the lateral. Ears oblong and rounded, moderate, 

 hairy. Claws of fore feet curved, compressed, strong. Hind feet 

 scarcely surpassing in size the fore feet, which are larger than com- 

 mon. Tail longer than body, thick, hairy. 



Tree-kangaroos, animals of New Guinea having a much darker fur than 

 most of the species of this family ; they climb on trees. Two species are 

 known: Dendrologus ursinus Sal. Mueller 1. 1. Tab. 19; — Dendrologus 

 inustus Sal. Mueller ibid. Tab. 20.
