 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. 5. Geopbilus flaws, De Geer. Mem. Ins. vii. p. 561 (1778) ( = longicornis, Leach). Kingston-on-Thames. This species is distinguishable from the rest of the British species by its long and cylin- drical antennal segments. 6. Geopbilus carpophagus, Leach. Zoal. Misc. iii. p. 43. Weybridge, Kingston-on-Thames. 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. 7 Linotoenia crassipes, C. Koch. Deutschl. Crust, etc. pt. 3, pi. 3 (1835). 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. 8. Stigmatogaster subterraneus. Leach. Tr. Linn. Sac. Land. xi. p. 385 (1815). 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. 10.

Myr. p. 142 (1847). Kew Gardens. I 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. 177 N
