CHiETURA CAUD ACUTA. 



SPINE- TA I LED S WIFT. 



IT is quite impossible to give the definite range of the present species, as its powers of flight are 

 so immense that it might come from almost any region. It, however, visits the eastern portion 

 of Australia and Tasmania, and is also found in India and other parts of Asia, from which continent, 

 in fact, the visitors to Australia most probably come.
