Imecta Myriapoda found in Berwickshire. 489 



of the segments brown or yellowish, with a row of black spots 

 along the sides of the body." The feet are either pellucid 

 white or yellowish white ; and I have seen specimens with the 

 white and yellow intermixed ; the opposite legs of the same 

 pair even not being always alike. On being rudely handled, 

 a fluid transudes from the lateral pores, which has the same 

 peculiar penetrating odour which L sabulosus exhales when 

 bruised. 



3. I. punctatus. Reddish brown or very pale brown colour, the pores form- 

 ing a series of dark spots along each side ; anal segment with a short 

 cylindric obtuse mucro {fig. 43. a) Leach, in Linn. Trans., xi. 379. 

 Hab. Under stones and the bark of trees ; common. 



Body from 8 to 10 lines in length : head pale with a dusky 

 fascia across the front, smooth, the anterior margin fringed 

 with hairs : eyes black : antennas pale, dusky towards the 

 apex, hispid : post-occipital segment smooth with dusky mar- 

 gins : segments about 60, striate in a longitudinal direction, 

 generally a very pale brown, sometimes reddish brown, 

 marked on each side with a dark spot, and there is a series 

 of more obscure spots along the back, but these are some- 

 times wanting, especially on the posterior segments : anal 

 segment yellowish brown, smooth, the mucro short, obtuse : 

 legs clear white, somewhat hispid. — In pale-coloured indi- 

 viduals, the dark spots on the sides are very obvious and 

 form a striking character ; but in the darker specimens these 

 spots are less obvious and require to be looked for. It differs 

 from the /. niger in being always less ; in its colour ; in the 

 form of the anal mucro (Jig. 43. a) ; and in having more nu- 

 merous segments, for in a large specimen of the niger I 

 could not count more than 50; while in a specimen of the 

 punctatus, scarcely half the size, there were 57 5 or thereabouts. 

 Of their distinctness as species there can, therefore, belittle 

 doubt. Our animal is certainly not /. terrestris of Leach ; for 

 he says its stria? are much stronger than in I. niger, which is 

 not the case in ours. 



** Segments smooth dor sally. 



4. I. pulchellus. Narrow, cylindrical, sparingly hirsute ; anal segment sub- 

 mucronate. Length 5 — 7 lines.
