On the return of the ' Nimrod ' from the Antarctic, a stay of 

 nearly a month in New South Wales, and a few days in Queens-

 Rotifera, etc.

 in the Blue Mountains and Australian Alps. In the cool climate 

 of the Alps the Rotifer fauna closely resembled that of Britain,

 Mountain region was very much more productive, and all the new 

 species were obtained there.
