The second image shows the tail and the terminal claw which in this species has a characteristic large secondary claw with a tuft of spinules at the base. Thanks to Eric Hollowday of the Quekett Microscopical Club for guiding me through the identification at the recent Quekett Expedition to Basingstoke Canal.
