about I foot to 2 feet deep, and though of long standing are 

 doubtless artificial. Sphagnum grows more or less luxuri- 

 antly in most of them, and where the margins are not too 

 steep other vegetation, Rushes (/uncus sp.), Sedges (Carex 

 sp.), Water-grass {Glycerin fluitans), Ranunculus flammula, 

 etc., is present. Close to the corner of the moor where the 

 pools are is a house with garden and grounds, which accounts 

 for the number of tin cans and other rubbish which one 

 finds in them. Though a few examples of L. glabra occur 

 in an adjoining ditch it was there that Mr Evans first 

 discovered it in April 1 891 the pools are its headquarters. 

 In one of the latter it is still plentiful, Mr Evans having ' 

 seen it there as late as May 191 7. Many were clinging to 

 pieces of submerged wood. The elevation of the moor is 

 about 900 ft., and no other mollusc has been observed in the 



pools. 



In 1897, October 20th, Mr Evans found it in a curling- 

 pond near Rosslyn, fairly common and well grown, amongst 

 Equisetum. These were seen and authenticated by us. 



V.C. 84. Linlithgowshire. The only records we have for 

 this vice-county are of ancient date, but we have no reason 

 to doubt their authenticity. 



In 181 1 Laskey wrote in his " Account of North British 

 Testacea," (Mem. Wernerian Nat. Hist. Soc, 181 1, i. 417) 

 that it was " found by the Reverend Mr Fleming in ditches 

 in Linlithgowshire, who added several specimens to my 

 cabinet"; recording it as Helix octona, Penn., H. octanfracta, 

 Mont. If the Laskey collection is extant at the present 

 day, it would be of interest to have the specimens examined. 



V.C. 86. Stirlingshire. The species was found at Falkirk 

 on the 27th October last (1917) by Mr George Nelson, who 

 has rendered me much valuable help in working out the 

 mollusca of his neighbourhood. On that date he found 

 examples both mature and immature in a roadside pool on 

 the Drum Road. He again visited the place on the 20th 

 November, when he collected a few adults (which have 

 been deposited in the Royal Scottish Museum) and saw 

 about a dozen more partly grown as well as thirty or forty 

 very minute examples. At the same time he gathered
