MYRIAPODA 



southern counties. Occurs also in the western 

 countries of central Europe. 



15. Brachydesmus superus, Latzel. Die Myriap. 



(Ester. Ungar. Man. ii. 130 (1884). 

 Finchingfield, Walton-on-the-Nazc. 



CHORDEUMIDJE 



Millipedes with typically thirty segments furnished dorsally with six symmetrically 

 disposed bristles, without scent-glands and usually keeled like those of the Polydesmidse. 



16. Atractosoma polydesmoiJes, Leach. Zool. 



Misc. iii. 36 (1817). 

 Brentwood, Finchingfield, Warley. 



This species, with its large keels, closely 

 resembles an elongate Polydesmus. 



IVLIDJE 



Millipedes in which the body consists of a large but variable number of segments, each 

 of which, excepting the most anterior, is furnished with scent glands, but without the keels 

 characteristic of the Polydesmidae. 



17. lulus sabulosus, Linn. Syst. Nat. ed. 10, 



P- 639 (1758). 

 Walton-on-the-Naze, Chelmsford, Widford. 



A large species with acute caudal prolonga- 

 tion and a pair of yellow longitudinal dorsal 

 stripes. 



1 8. lulus niger. Leach. Zool. Mix, iii. 34 



(1817). 

 Warley. 



Common in England and in the western 

 countries of the continent. As large as the 

 preceding but slenderer, without dorsal bands, 

 and with the anterior portion of the segments 

 transversely grooved. 



19. lulus ligulifer, Latzel. Berl. Ent. Ztits. 



xxxvi. 152 (1891). 

 Stock, Warley. 



A small black -tailed species, without 

 stripes and without transverse grooves on the 

 segments. Fairly common in central Europe 

 and no doubt also in England, though not 

 previously recorded as British. 



20. lulus pilosus, Newport. Ann. Mag. Nat. 



Hist. xi. 316 (1842). 

 Warley. 



Very nearly allied to /. ligulifer, and prob- 

 ably often confounded with that species so far 

 as the females are concerned. The males of 

 the two are easily distinguishable by the form 

 of the first pair of legs. 



21. lulus punctatuiy Leach. Zool. Afiic. iii. 



Warley. 



A yellowish-brown species, with a blunt 

 expanded caudal process and a row of dark 

 spots on each side of the body. Found in 

 rotten wood. Common throughout England 

 and on the continent. 



22. lulus teutonicus, Pocock. Ann. Mag. Nat. 



Hist. (7), vi. 206 (1900). 

 Stock, Warley, Colchester, Great Baddow, 

 Dagenham. 



This species, which is common at least in 

 the south-eastern counties of England and in 

 the western countries of Europe, has errone- 

 ously passed until recently under the name 

 lulus londinensis. With exception of the lat- 

 ter, which has never been discovered since 

 Leach's time, /. teutonicus is the largest tailless 

 form of this genus met with in Britain. 



lulus londinensis, Leach (TV. Linn. Sac. xi. 

 378 [1815]), described from the environs of 

 London, may prove to belong to the fauna of 

 Essex. 



23. Blaniului guttulatus, Bosc. Bull. Sac. 



Philom. p. 12 (1792). 

 Finchingfield. 



A long and slender eyeless species, with 

 the head and anterior segments pale, and a 

 line of blood-red spots on each side of the 

 body. 



POLYXENID^: 

 Syst. Nat. ed. 



24. Polyxenus lagurus. Linn. 



'0, P- 637 (1758). 

 Brightlingsea. 



This species is commonly found beneath 

 the loose bark of old fences or tree trunks. 



The examples above recorded however were 

 collected beneath weeds upon the beach. In 

 spite, however, of the peculiarity of the 

 habitat, they seem to belong to P. lagurus, the 

 common European species of the genus.
