So far as yet known this species has only been found in Scotland 

 in Lochend Loch, Edinburgh. A parcel of mud which was sent 

 me by Mr. James Bennie, contained some single valves of it. In 

 hopes to procure living examples I made a further search, but 

 failed to find any but dead shells. The loch at this time was 

 being drained and filled up with rubbish from the town, which 

 gives reason to suspect that the species had been killed by the 

 poisonous nature of the refuse. The process of filling up has been 

 abandoned, and the loch has been full of water for some time. I 

 have tried for the same species since, but without finding a trace of 

 it. That may arise, however, not from its extinction in the loch, 

 but because the former gatherings were from mud in very low 

 water, when the loch was partially drained, and the latter from 

 the high margins when the loch was in flood. A boat and dredge 

 may now be required to obtain it.
