Mr. J. W. Taylor remarked, in reference to Mr. Nelson's 

 paper on the " Association of Species," read at last meeting, that 

 he had received from Mr. Butterell of Beverley a confirmation of 

 Mr. Nelson's views as to Planorbis spirorbis and Limncea glabra 

 being usually associated in the same locality. Mr. Taylor pointed 

 out that this association was not invariable, and named several 

 localities where it did not occur.
