162 ANNALS OF SCOTTISH NATURAL HISTORY 



THE FALSE-SCORPIONS OF THE WEST OF 



SCOTLAND. 



By ROBERT GODFREY. 



THE following list of False-scorpions known to occur in the 

 West of Scotland is given in the hope that it may rouse the 

 interest of other naturalists in this little-studied group. It 

 contains seven species, in comparison with eight known from 

 the East coast. Of the seven, three have not yet been taken 

 in the Eastern division of Scotland, and two of these are 

 new to the Scottish list. The list has, however, some very 

 conspicuous omissions : Cheiridium innseorum (Leach), e.g., 

 ought to be as common here as in the East of Scotland, 

 though it has so far eluded my search in haylofts and other 

 likely places ; Chelifer rufeolus, Simon, ought also to be 

 discovered in old byres and barns ; and, during the months 

 of August and September, Chelifer nodosus, Schrank, should 

 be occasionally at least seen clinging to the legs of flies 

 on our window panes. Then, again, Chelifer cimicoides, F., 

 and other species which live under the bark of old trees in 

 England, should yet be found in similar situations in the 

 S.W. of Scotland. Careful search would, I have no 

 doubt, soon raise our list to nearly double its present 

 number. 



CHELIFER DUBIUS (Cambridge). Two individuals, found in com- 

 pany with Ideoroncus cambridgii and Chthonins rayi, were 

 taken by Mr. Robert Whyte on a piece of driftwood near 

 Balmacara House, Ross-shire, on August 27, 1906. Ch. 

 dubius makes a nest for moulting purposes only. The adults 

 do not hibernate inside nests, nor does the female make any 

 nest for the purposes of reproduction, but simply carries her 

 embryonic mass about with her attached to the under surface 

 of her hind-body. 



CHELIFER CANCROIDES (Linn.}. This species was added to the 

 Scottish list on April 2, 1907, on the strength of a single 

 specimen found among hayseed in a Glasgow stable. Later 

 search, however, revealed a large colony living in the joints of 

 old harness buried in the hayseed. On April 29, Robert
