144 NOTES ON ZOOLOGY OP THE MACLAY-COAST. 



to what extent it is impossible for me to form an opinion, on 

 account of the absence of the second kiteral incisor in the 

 specimen of Macropus Brownii in the Australian Museum. (1) 



The Macropus tihol is also completely difterent from all the 

 Macropi of the south coast of New Guinea that have been as 

 yet described.

(1) About the dentition of M. Brownii Mr, Alston says: — "The third 

 upper incisor is but little longer than the second, and has the external fold 

 close to its posterior border." E. R. Alston, loc. cit- Proc. Zool. Soc, 

 1877, p. 123.
