succeeded in killing one towards daylight, -which is the specimen now

Mr. George Bennett stated that wliile in New South Wales he had 

 heard of an animal called Gunar by the natives, and found about the 

 Beran Plains, which was described to him as in some degree resem- 

 bling a Kangaroo, but differing from it in having a bushy tail, and 

 in the form of the head, which was stated to resemble that of the 

 Hare. He suggested the probability that the Gunar and the brush- 

 tailed Kangaroo might be specifically identical.
