A specimen was exhibited of the brush-tailed Kangaroo, Macropiig 

 penicillatus. Gray, which had recently been presented to the Society 

 by Captain Sir Edwai'd W. Pany. Mr. Bennett called the attention 

 of the Meeting to its peculiarities, and remarked on the great hairi- 

 ness of the tail, and especially on its want of robustness at the base, 

 as indicating probably the tj^pe of a new genus, to be removed from 

 among the Macropi on account of the diminished power of an organ 

 which is so exceedingly strong among the typical Kangaroos as to exe- 

 cute, during the act of slow progression and while resting, the office of 

 a third leg. In connexion with this peculiarity of tail, Mr. Bennett 

 pointed out also a difference in the form of the third, or extreme la- 

 teral, incisor, as compared with the corresponding tooth in Macr. 

 major, Shaw ; crania of the two animals Ijeing exhibited for that 

 purpose. The third incisor in Macr. penicillatus is bilobed, and ap- 

 proaches somewhat to the character of the corresponding tooth in 

 Macr. Parryi, Benn. 



A note by Sir Edward Parry, which accompanied the specimen, 

 was read. The animal appears to be procurable with difficulty, as 

 this individual was " the only one of the kind ever seen by Sir E. 

 Parry. It was shot among rocks near Liverpool Plains, New South 

 Wales. As several of the same kind were seen together on more 

 than oiie occasion, they appear to be gregarious. They seemed to 

 prefer the neighbourhood of rocky ground, in which they had holes, 

 to which, when hunted, they retreated. The first intimation re- 

 ceived of these animals by Mr. Hall was, that monkeys were to be 

 seen in a particular situation : and the manner in which they jumped 

 about, when he first approached a number of them, left the same im- 

 pression on his mind. They were so wild that he found it impossi- 

 ble, on his first attempt,' to obtain a specimen ; and one which he 

 had wounded escaped into its hole. Some months afterwards, how- 

 ever, after remaining on the spot a whole night for the purpose, he
