The following are the localities from which I have had it identified : — 



Clubbie-dean pond, Pentlands, common, under a log at the water's edge, 

 Nov. 1907; Loch Gelly, Fife, abundant under rejectamenta, April 1905, and 

 Dec. 1907; near Aberdour, in moist earth, Feb. 1908; under stones beside the 

 Water of Leith above Balerno, March 1909. 



[Fam MEGASCOLECID^. 

 Pheretima ( = Perichseta) indica (Horst). 

 I have found this exotic species on several occasions in hot-houses in 

 Edinburgh, where, if allowed, it seems readily to establish itself. Presumably 

 it is not able to live out-of-doors in our climate. I once, however, found 

 one crawling at the side of the footpath in Morningside Park ; probably it 

 had dropped from a flower-pot during removal from a hot-house in the 

 neighbourhood. As Mr K. Service, who, in 1890, recorded 1 the establishment 

 of this Earth-worm in hot-houses in Kirkcudbrightshire, remarks, "it is a 

 hard, wiry, agile creature." I have seen one spring a distance of six or 



seven inches.] 



Fam. LUMBRICID^I. 



The Lumbricidai or typical Earth-worms have usually been recorded by 

 British naturalists under the three generic names Allurus, AllolobopJwra, 

 and Lumbricus. Following Dr Michaelsen, 2 Mr Southern, in his recent 

 paper to which reference has already been made, substitutes Eiseniella 

 for Allurus, and splits AllolobopJwra into three genera, Msenia, Helodrilus, 

 and Octolasium ; Helodrilus being again divided into four subgenera, namely, 

 AllolobopJwra, Dendrobmna, Helodrilus (EopJiila), and Bimastus. Repre- 

 sentatives of all these genera and subgenera occur in our area. 



Eiseniella tetraedra (Sav.). 



Allurus Lctracdrus, Beddard in Proc. Roy, Phys. Soc. Edin., vol. x. p. 208. 



As pointed out by Mr Beddard (I.e.) this is an amphibious species. In 

 the Forth district it is common in mud and under stones about the margins 

 of streams and ponds, often quite under the water. I have also found it 

 under the bark of an old log in a damp wood. The following list of 

 occurrences shows that it is widely distributed. 



Midlothian : — In stream at Nether Habbie's Howe, Pentland Hills, April 1 902 

 Kirknewton, under bark of rotten log in damp spot in wood, April 1903 

 Gladhouse Reservoir, under stones at the water's edge, common, Nov. 1904 

 Cobbinsliaw Reservoir, under Hood refuse, common, April 1905 ; margin of 

 river Almond, at Cramond Bridge, Dec. 1904; Lochend Loch, Oct. 1909; ditch
