 exhibited at a meeting of the Club in August 1862 ; and that 

 living specimens from the same canal at Woodley were 

 exhibited at a meeting in August 1864. In July 1885, Mr. E. 

 Collier and I collected one living and one dead example at 

 Woodley, but I have found none since, although I have 

 frequently searched the canal there and elsewhere. Mr. J. B. 

 Tomlin has recently taken specimens in the canal at Stone
