A HISTORY OF ESSEX 



CRYPTOPID^E 



Eyeless centipedes of medium length and thickness, with twenty-one pairs of short legs, 

 and though somewhat intermediate in form between the preceding and the succeeding families, 

 resembling the latter rather than the former in their slow movements. 





Cryptops hortensis, Leach. 

 Land. xi. 384 (1815). 

 Maldon, Warley. 



Tr. Linn. Sac. A widely distributed species, but never oc- 

 curring in any very great numbers. Abun- 

 dant all over central and southern Europe. 



GEOPHILID^: 

 Long-bodied vermiform centipedes without eyes, and furnished with a large but variable 



number of legs. 



5. Geophilus flavus, De Geer. Mem. Ins. vii. 



561 (1778) ( = longicornis, Leach). 

 Brentwood, Maldon, Stock, West Mersea 

 (under Zostera on the beach), Finching- 

 field, Warley, West Horndon, Dagenham, 

 Ingrave, Colchester. 



Common throughout Europe. Distinguish- 

 able from all the other British species by its 

 long antennal segments. 



6. Geophilus proximus, Koch. Syst. d. Myr. 



p. 1 86 (1847). 



Brentwood, Finchingfield, Colchester, Riven- 

 hall. 



Although widely distributed on the conti- 

 nent, this species, so far as our knowledge at 

 present extends, appears to be restricted in its 

 range to the eastern counties of Great Britain. 

 It may be distinguished by the presence of a 

 pair of short oval impressions on the sterna of 

 anterior segments of body. 



7. Geophilus carpophagus. Leach. Zool. Misc. 



iii. 43 (1817). 

 Brentwood, Warley. 



Common everywhere in England and on 

 the continent. Distinguishable by the ball 

 and socket method of articulation of the an- 

 terior sternal plates. 



8. Geophilus truncorum, Meinert. Nat. Tidskr. 



iv. 94 (1866). 

 Warley, Ingrave. 



A small species, often overlooked, but 

 ranging throughout the south of England 

 and Wales. Distinguishable by the presence 



of three strong grooves on the anterior sternal 

 plates. 



9. Linoteenia acuminata. Leach. Tr. Linn. 



Soc. Land. xi. 386 (1814). 

 Warley. 



Widely distributed in the south of England 

 and on the continent. 



10. Linoteenia crassipeSy Koch. Deutschl. Crust. 



etc. 3, pi. iii. (1835). 

 Brentwood, Warley, Ingrave, Colchester. 

 This species has the same distribution as 

 the last, to which it is nearly allied. The 

 two are the common British luminous centi- 

 pedes which frequently attract attention on 

 damp evenings in the autumn by the emission 

 of a phosphorescent secretion from their ster- 

 nal glands. 



11. Linoteenia maritima, Leach. Zool. Misc. 



iii. 44 (1817). 



West Mersea (under Zostera on the beach). 

 Fairly common in suitable localities round 

 the coasts of Great Britain and on those of 

 western Europe, living beneath stones be- 

 tween tide marks or under accumulated sea- 

 weed left by the tide. 



12. Schendyla nemorensis, Koch. Deutschl. 



Crust, etc. 9, pi. 4 (1837). 

 Warley. 



A small and delicate centipede of about the 

 same size and general appearance as G. trun- 

 corum. Found under tree trunks and stones 

 in woods, etc., throughout England and cen- 

 tral Europe. 



DIPLOPODA 



Millipedes 

 POLYDESMIDJE 



Millipedes with from nineteen to twenty body segments, most of which are furnished 

 with paired scent-glands supported on a larger or smaller lateral crest or keel.
