54 EXTINCT AND VANISHING MAMMALS 



they were unfortunately slaughtered by shooters from the town. (Troughton, 

 1932, p. 220.) 



In Victoria this Bilby was always confined to the northwestern 

 corner of the state, and the last record was in 1860 (C. W. Brazenor, 

 in Hit., March 3, 1937) . 



Jones (1923a, p. 342) speaks of examining a living specimen from 

 Queensland. Finlayson states (1934, p. 229) that it is apparently 

 absent from the Dawson Valley, Queensland, but that it occurs at 

 Epping in the Clermont district, 150 miles northwestward.

Australia.")

.This subspecies is apparently extinct (Troughton, 1932, p. 230). 



It is the largest subspecies; its ear, however, is proportionately 

 shorter than in the other subspecies. Head and body, 550 mm.; 

 tail, 260 mm.; ear, 77 mm. 



It is known only from the "South-east of South Australia" (Ire- 

 dale and Troughton, 1934, p. 20) . 



Before this form was distinguished from the typical lagotis, 

 Jones (1924, pp. 156-157) wrote of it as follows: 



Thalacomys lagotis, though formerly abundant in South Australia, is now 

 either extinct or on the verge of extinction. It was the familiar species of 

 Bilby in the more fertile portions of South Australia only a comparatively 

 short time ago. Not more than thirty years since it was usual for rabbit 

 trappers, even in the immediate neighbourhood of Adelaide, to take more 

 Bilbies of this type than rabbits in their traps. This race . . . apparently had 

 its last South Australian stronghold at Nalpa and in the wide tract of 

 country about Lake Alexandrina; but from Nalpa it has long since disappeared, 

 and it seems most probable that the animal is now extinct in this State. 



Rawlinna Bilby 



MACROTIS LAGOTIS INTERJECTA Troughton 



Macrotis lagotis interjecta Troughton, Australian Zool., vol. 7, pt. 3, p. 227, 

 1932. ("Rawlinna, Trans-Australian Railway, Western Australia.") 



This subspecies seems to be known definitely from only two 

 specimens, both taken at the type locality. 



^Smaller than the western lagotis; fur shorter and more woolly; 

 general color more drab-gray and less contrasting; under parts 

 whitish; black portion of tail equaling, or shorter than, the white
