154 BIOLOGY OF SNOWY RIVER AREA 



The foregoing is a very incomplete record of the rocks occurring 

 in the area, but it may serve a useful purpose in giving some 

 indication of the great amount of work yet to be done there. 



I am indebted to Messrs. G. Baker and A. Gaskin of the 

 Geology School, Melbourne University, for helpful discussion, and 

 to Messrs. A. Hodge and C. Sykes, of Gelantipy, for assistance 

 in the field.

Rock Wallabies were at one time very numerous throughout the 

 Snowy River area, but unrestricted hunting, a disease epidemic, 

 or possibly a combination of the two, drastically reduced their 

 numbers in the early part of the present century. For more 

 than 30 years, no Victorian specimen has been recorded at the 

 National Museum, and the species has been considered extinct in 

 that State. 



A small colony was found on a mountainside at Suggan Bug- 

 gan. It was estimated that it consisted of 10 to 12 individuals 

 which, from observation, appeared to lead a nomadic existence 

 over a little more than a mile of rocky outcrop. The site is un-
