HYPSIPBYMNUS PENICILLATUS. 183 



Kangurus Gaimardii of Desmarest, and the Hypsi- 

 prymnus White of Quoy and Gaimard. A drawing 

 of the skull of this animal, lent me by Professor Owen, 

 together with a careful description, taken from the 

 specimen by myself, leave no doubt on my mind of 

 the accuracy of the above conclusion ; the dimensions 

 of the Paris specimen are as follows : from nose to 

 root of tail, 13^ inches; tail, 13 inches; tarsus, to 

 base of claws, 4 inches 1 line ; ear, 1 kich ; from 

 nose to ear, 2 inches 9^ lines. From a careful ex- 

 amination of the H. formosus of Mr. Ogilby (Proc. 

 Zool. Soc. for May 1838, p. 62,) I feel convinced 

 that it is the young of the present species. In the 

 College of Surgeons is a similar specimen, the skull 

 of which exhibits all the usual characters of a young 

 animal. The H. formosus is 1 1 inches in length, 

 without including the tail, which measures 1 inches 

 its colouring is somewhat richer, there being a 

 greater admixture of yellow in the tint of the fur. 



H. Whitei appears to be tolerably common in New 

 South Wales.
