Of fifteen specimens shot and captured alive, the length of the males averaged from 
1 foot 7 to 1 foot 8 inches (measuring from the extremity of the mandibles to that of 
the tail) ; and that of the females from 1 foot 6 to 1 foot 7 inches. 
During my stay at Gudarigby, the farm of Mr. W. H. Dutton, near the Murrum- 
bidgee River, a male was shot which measured 1 foot 113 inches in length ; but the 
relative proportions of the other parts were not so great as might have been expected.
