 Edinburgh it is common, and, to all appearance, quite estab- 

 lished, examples of all ages being present.^

Family CHORDEUMID^. 

 Atractosoma polydesmoides (Leach). 



Atractosoma latzeli, Verhoeff", 1891. 



Although fairly well distributed and not rare, this easily 

 recognised species cannot be said to be of frequent 

 occurrence here. Its usual habitat is under planks and 

 stones. First recorded from Scotland by myself (126), and 

 subsequently from " Clyde " by Boyd (13). Common in 

 south of England, and recorded also from Ireland (Pocock, 9). 

 Has apparently not yet been found outside the British 

 Isles, where, according to Pocock, it (he uses the name 

 A. polydesmoides) is the only known representative of the 

 genus. I assume, therefore, that Verhoeff's A. latzeli from 

 the south of England (8) is the same as Leach's species.

Oraspedosoma rawlinsii, Leach. 



To us this species is of special interest, seeing Leach's 

 types were got in this district. Writing in 1814, Leach 



1 A few other foreign Myriapods, including Polydesmus coriaceus, Porat 

 {6 S 9 9 common, !B.), and the Geophilid Mecistocephalus carniolensis, 

 C. L. K., have been found living in hot-houses at the Botanic Garden.
