Genus Helodrilus, Hoffmstr., em. Mchlsn. 



Tlie following three species are placed by Michaelsen in the subgenus 

 Allolobophora, Eisen : — 



Helodrilus (A.) caliginosus (Sav.). 



Abundant in fields, gardens, old pastures, etc., throughout the area. So 

 far the var. trapezoid.es has not been detected here. 



Specimens have been examined from the following localities : — 



Midlothian: — Fairmilehead and Temple, many turned up by the plough, 

 Feb. 1904, and Feb. 1905; under stones by side of the Almond at Cramond 

 Bridge, Dec. 1904; Pentland Hills above Hillend, and in road-scrapings at 

 Polton, March 1905; banks of Water of Leith above Ravelrig, March 1909; 

 field near Granton, March 1910. East Lothian: — Roadside near Gifford, April 

 1905 ; Aberlady, in garden, April 1907 ; side of Tyne above Hailes, April. West 

 Lothian : - Carriden, near Bo'ness, March 1910. Stirling : — near Falkirk, common,

Helodrilus (A.) longus (Ude). 



Allolobophora terreslris, Beddard's table (I.e.). 



Common in fields, about roadsides, etc., and widely distributed. 



Localities are: — Field at Fairmilehead, Feb.; Polton, in road-scrapings, 

 March; Pentlands above Hillend, March 1905; Bolton, near Haddington, April

 Falkirk, March 1910; Thornton, Fife, March 1910; Isle of May, one, Jnne 1909. 



Helodrilus (A.) chloroticus (Sav.). 

 The Green-worm, as it may well be called, is common and generally dis- 

 tributed in the district, ranging from sea-level almost to the tops of the highest 

 hills. Under a stone on the margin of a stream is a favourite habitat. When 

 disturbed it curls itself into a circle, as Beddard (I.e.) and others have 

 remarked. Some examples are much greener than others, and I have seen 

 several of a distinctly reddish colour. 



Localities: — Ditch near Balerno, and road-scrapings at Polton, March 1905; 

 Water of Loith above Currie, common under stones, April 1908; Boltonmoor,

 Uct. 1908; side of Tyne, near Kast Linton, April 1910; Carriden and Blackness, 

 March 1910; near Falkirk, common at roots of hedge, March 1910; Dunblane 

 ;md Bridge of Allan, April and Dec. 1905; Callander, and near summit of 

 Stuc-a-Chroin (.'5000 ft.), Sept. 1906; Balquhidder, from bottom of valley up to 

 1500 ft. (see p. Ill), April 1910; Charlestown, Fife, turned up by plough, Feb.; 

 and Loch (Icily, common under Hood refuse, April 1905; Isle of May, one under 

 tone, Sept,. L909.
