The Oligochreta of the Forth Area. 115 



month (March 1910) ; and no doubt it occurs in similar situations all 

 along the coasts. Identification confirmed by Mr Friend. It is a very 

 papillated worm, as shown in Beddard's figure (I.e.) from a Plymouth specimen. 



Tubifex costatus (Clap.). 



Psammoryctes costatus, Michaelsen's " Oligochaeta," p. 52. 

 In June 1909 a few examples of this species were found under a stone 

 in a muddy bay about a mile east of Dunbar, Haddingtonshire. For their 

 determination I am indebted to Mr Southern. Both this and the previous 

 species appear to be additions to the Scottish list. 



Fam. LUMBRICULID^. 

 Lumbriculus variegatus (Mull.). 



Lumbricus teres, Dalyell, "Powers of the Creator," vol. ii., 1853, p. 140. 



This interesting aquatic worm is common in pools, ponds, ditches, and 

 slow streams in most, if not all, parts of the area. It is very quick in its 

 movements, and requires care in preservation to prevent it breaking itself 

 into pieces. 



My localities for it are : — 



Bavelaw Moss, abundant in submerged sphagnum, May and Nov. 1904 ; Upper 

 Elf Loch, Braid Hills, Oct. 1904, etc. (Ann. S. N. H., 1905, p. 215) ; pond near 

 Kirknewton, common among submerged leaves, March 1905; Logan Water, 

 Pentlands, Dec. 1906; pond in Botanic Garden, Edinburgh, May 1909; ditch 

 at Hallyards, near Kirkliston, March 1910; Camilla Loch, Fife, Aug. 1906; 

 ditch in wood near Thornton, March 1910; Lake of Menteifch, June. 



Fam. ENCHYTR^nXE. 

 Henlea ventriculosa (Udek.). 

 Doubtless common. Mr Southern has determined specimens for me 

 from the under-noted localities : — 



Margin of Clubbiedean Pond, Pentland Hills, a good many under log, 

 15th Nov. 1907; Loch Gelly, Fife, under rejectamenta, 26th Dec. 1907; at roots 

 of plants in garden, Morningside, 19th January 1908. 



Marionina sphagnetorum (Vejd.). 

 Probably common on elevated moors, but easily overlooked owing to its 

 small size. Specimens from a tuft of sphagnum and hepatics on Dunbar 

 Common, Lammermuir Hills, at about 1000 ft. above sea-level, 10th Oct. 

 1908, and from near Thornton, Fife, March 1910, were determined by 

 Southern. I have also observed it at Bavelaw Moss on the north side of the 

 Pentlands, and on Ben Ledi at about 2500 ft., Sept. 1906.
