The Myriapods of the Forth Area. 409 



Lithobius variegatus, Leach. 

 This fine species, which is generally regarded as confined 

 to the British Islands and Jersey, appears to be almost 

 entirely of western distribution in Scotland (cf. Gibson- 

 Carmichael, 7, p. 240) : it is common, for instance, about 

 Oban. In the Forth area it occurs sparingly in the oak 

 woods at the head of the valley. I have not yet detected it 

 farther east than Culross. 



Local data. — Neiglibourhood of Loch Katrme, rare (Gibson-Carinichael, 

 I.e.); and I believe I met with it iu the woods bordering Loch Ard, in April 

 1902, though I cannot now lay my Lands on the specimen. One under stone 

 in wood near Culross, 26th April 1901, !P. 



Lithobius melanops, Newp. 



Lithobius glahratus, C. L. Koch. 



This form is common, and widely distributed with us, and 

 has already been recorded by me (125). A favourite habitat 

 is under bark on a dead tree ; but it occurs with equal 

 frequency under stones. Eecorded from south of England 

 (14), Ireland (9, 11), Norway, and other parts of Europe. 



Local data. — Ravelrig, near Balerno, common under bark on dead fir, 

 April 1901, !P.; Hillend Wood, Pentlands, March 1902; Listonshiels, Sept. 

 1905; Roslin Woods, April 1906; Culross, April 1901, !P.; Blairadam, under 

 bark. May 1905; West Weniyss, !E., and North Queensferry, common under 

 stones, April 1905; Elie, Aug. 1904; North Berwick, Nov. 1905, several (some 

 young); Bo'ness, May 1901 (from R. Godfrey); near Bridge of Allan, April 1906. 



Lithobius calcaratus, C L. Koch. 

 Common under stones, turfs, etc., chiefly on moors and 

 hillsides. Eecorded by me in 1901 (12&). Colour usually a 

 dark blackish-brown. Pocock (14) records it from Hamp- 

 shire. Frequent in North Europe. 



Local data. — Bavelaw Moss, two, May 1900 (determined by Pocock) ; woods 

 and moors near Kirknewton, one, Jan. 1902, common, April 1905; Blackford 

 Hill, one, JMnrch 1905; summit of Caerketton, Pentlands, common under 

 stones, March 1906, ! B,, ! E. ; Tyninghame, one in Moss, May; East Grange, 

 Fife, April 1901 ; Aberfoyle, July 1900; hillsides, near Callander, April 1900, 

 !P.; etc. 



Lithobius borealis, Mein. ? 

 A Lithuhiits, unfortunately somewhat damaged, from Ben 

 Ledi is, Mr Elliugsen thinks, this species, which has already
