 dividuals of this species were taken alive. Two of these were collected 

 in shallow water near Grapevine Point. Douglas Lake; one, floating at 

 the surface although still able to move when disturbed, July 20. 1911, 

 and the other in a drag-seine, Aiigust 10. 1915. Both animals died

 Bryant's Dock, Douglas Lake, August 15, 191.3. and seemed in very 

 good condition, living in the Biological Station aquarium for several 

 days. A few dead, beached specimens of this species were found each
