TURBELLARIA 



The Turbellaria or flat-worms of Cornwall have up to the present received very little attention. 

 Dr. Cocks recorded a few from Falmouth, but the only publication of importance on the subject is 

 'The Turbellaria of Plymouth Sound,' by Dr. F. W. Gamble (Journ. Marine Biol. dssoc. iii). 

 The following is a list of the species recorded by Dr. Gamble, all of which were obtained in the 

 Plymouth district. A few additional localities have been added where there was no doubt about the 

 identification :
