Habitat. — With the last ; rather rare. 



The most northeily Ihnit of distribution hitherto 

 observed for this species in Scotland seems to be the 

 Island of Lewis, In Clydesdale and the Forth 

 district it has been observed in a number of localities.

Habitat. — In the pools with Cypris prasina; common.

 few of the Ostracoda can be got without the use of
