156 ANNALS OF SCOTTISH NATURAL HISTORY 



extend its rancfc. In the few recorded cases where 

 specimens of Chcmes uodosus have been found in a book or 

 among papers, it is quite likely that they have reached 

 such positions after having slipped from the leg of their 

 carrier. 



Man unwittingly takes a large share in the distribution 

 of False-scorpions. Through his agency, species which dwell 

 among plant-mould and in the refuse of mills and of stables 

 are carried from place to place. Species also which live in 

 wood — whether on the natural tree or on the finished 

 article of joiner)^ — are also to some extent indebted to him 

 for their extension of range. 



' Scottish Distribution. 



The number of Scottish species (July 1907) is twelve, 

 a number which ought to be considerably increased as 

 interest in the group extends. In this number not a single 

 species of the forest group — the tree-haunting Chernes — is 

 included, but it is unlikely that such a gap exists in our 

 native fauna. A careful examination of the old trees that 

 are left to us as relics of the ancient Scottish forests ought 

 to result in the discovery of several species of False-scorpions 

 not as yet on the Scottish list. The sifting of the 

 materials of ant-heaps ought in Scotland as elsewhere to 

 lead to the detection of False-scorpions living there as 

 guests, and the careful examination of refuse in our gran- 

 aries and stores at seaport towns would very probably lead 

 to the discovery of several exotic species living and thriving 

 in Scotland. 



Much work remains to be done in tracing the distribu- 

 tion of the species in Scotland. From " Forth," " Clyde," 

 and "West Ross" eight species are known ; "Argyle" and 

 " Tay " have five each ; " Solway " has four ; " Tweed " has 

 three ; " Moray " and the " Inner Hebrides " have one each ; 

 while the five faunal areas of " Shetland," " Orkney," 

 "Outer Hebrides," "Sutherland," and "Dee" are wholly 

 unrepresented. These facts are sufficient to show how 

 comparatively unworked Scotland still is in this particular 

 branch of natural history.
