MYRIAPODA 



Since the species typically belongs to the 

 fauna of the Mediterranean area and has 

 hitherto not been met with elsewhere in 

 Great Britain nor so far north as London in 

 any of the countries of Europe, suspicion 

 must necessarily rest upon its claim to rank as 

 an indigenous English form. But since the 

 spot where the specimens were captured lies in 

 the open remote from the conservatories where 

 the rest of the imported species are procured, 

 it seems probable that the species is in a fair 



way to establish itself in this country and to 

 take its place in our fauna alongside of such 

 forms as the black and brown rat, several 

 species of cockroaches and other familiar species 

 which are known to have been introduced. 



C. anomolans is a much larger form than 

 C. kortensis, often measuring over 30 mm. in 

 total length, and further differing from it in 

 having the dorsal plate of the first tergite 

 transversely sulcate in front and overlapped 

 by the head shield. 



GEOPHILID^E 



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

 number of legs.

This species is distinguishable from the rest 

 of the British species by its long and cylin- 

 drical antennal segments.

Differing from the preceding and from the 

 rest of the British species by the ' ball and 

 socket ' method of articulation of the anterior 

 sternal plates.

 Charterhouse (O. Latter). 



This species and its congener L. acuminata 

 are the two common British luminous centi- 

 pedes which so frequently attract attention 

 on damp evenings in the autumn by the 

 emission of a phosphorescent secretion from 

 their ventral glands. They may be distin- 

 guished from Geophilus by the presence of a 

 tooth at the base of the fang on the poison 

 jaws.

 Kew. 



One of the largest British species of this 

 family, distinguishable by its inflated thickly 

 porous anal pleurae. 



DIPLOPODA 



Millipedes 



GLOMERID.& 



Short broad millipedes with the body composed of only twelve segments and capable of 

 being spherically rolled. 



Glomeris marginata, Villers. 

 iv. p. 187 (1789). 



Linn. Entom. known to occur in Britain. It presents a 

 close similarity to the ordinary pill woodlouse 

 (Armadillo vulgaris), but may be distinguished 

 from it at a glance by its large posterior ter- 

 gite and the narrow white band with which 

 all its tergites are bordered. 



Wimbledon (B. G. Rye). 



The species, the common pill millipede, is 

 the only representative of the genus Glomeris 



POLYDESMID/E 



Millipedes in which the body consists of from nineteen to twenty segments, most of 

 which in all the British species are furnished with repugnatorial pores supported on a larger 

 or smaller lateral crest or keel.

Imported and of common occurrence in 

 many of the conservatories in England and 

 other countries of Europe, where it breeds in 

 profusion. The immature form is pale, but 

 the adult is polished and of a rich brown hue 

 with yellow keels.
