﻿The Myriapods of the Forth Area. 



Ill 



shuns the higher treeless tracts. A favourite habitat is under 

 bark and moss on a rotten tree or among dead leaves, but I 

 find it also under stones and planks in old quarries and by 

 the sides of fields, etc. A common European species, ranging 

 west to Norway and Ireland. 



Local data. — Harburn, under log, ad., Oct. 1895; Mortonhall, under bark 

 and moss, and quarry near Swanston, common under stones, March 1901 and 

 other years, !P. ; Duddingston, ad., Roslin, Penicuik, and Balerno (where young 

 only 3 to 4 ram. in length were found), April ; Kirknewton Woods, March, IE. ; 

 Edinburgh Botanic Garden, Feb. and Oct. ; Ormiston Hall, March, and near 

 Gifford, April; Dalmeny Park, March and May; Craigie Hill, ad. i , April; 

 Abercorn Glen, May; near Bo'ness, adults, young, and eggs, June; CuUalo, 

 Fife, ad. and several imm., Feb. ; St David's, young, length 7 mm., segments 18, 

 nearly white, Sept.; Aberdour, Oct. ; Culross and Tulliallan, April ; Bridge of 

 Allan, April ; Callander, Sept. ; etc. 



Polydesmus denticulatus, C. L. Koch, ? 



Females of a smallish Polydesmus found on a few occasions 

 probably belong to this species ; but as Mr Brolemann, who 

 has seen a specimen, remarks, one cannot make sure of the 

 species without examining an adult male. Tbey accord ^vell 

 with Norwegian specimens kindly sent me by Mr EUingsen. 



Local data — Abbey Craig, near Stirling, two, Oct. 1901 ; Leadburn, one, 

 March 1905 ; Kirknewton, one, March 1906. 



Brachydesmus superus, Latz. 



Apparently rare, but it is an insignificant species, and 

 liable to be passed over as a young Polydesmus. My speci- 

 mens agree perfectly with Norwegian ones. Eecorded from 

 England (common) and Ireland ; and Sinclair (15) states 

 that he has found it in the north of Scotland. In this genus 

 the full number of body-segments is 19, as against 20 in 

 Polydesmus. This, it has to be remembered, applies only to 

 adults. 



Local data. — Kincardine-on-Forth, two ? ? , April 1901 ; foot of Cocklerue, 

 Linlithgow, two $ i and a ? , under stone, Jan. 1902. 



[Paradesmus gracilis (C. L. Koch). 



Originally imported, doubtless with exotic plants, this 

 tropical species is now found in hot-houses over most of
