Since the publication of " A Synopsis of the False-Scorpions of Britain and 

 Ireland " in these Proceedings in 1911 (20), two additions have been made 

 to this part of our fauna : one in Britain and one in Ireland. The former is 

 a Chelifer (Chernes), allied to Chelifer (Chernes) Wideri C. L. Koch, and 

 found in several places in England and Wales ; while the latter is a 

 Chthonius, a small and very distinct species, the discovery of which by 

 Mr. J. N. Halbert, m.r.i.a., at Malahide, Co. Dublin, is oue of the surprises 

 of recent field-work in Ireland. After a prolonged investigation, both have 

 to be established as new species. Moreover, the known false-seorpion-fauna 

 of Ireland has been enriched, during the last few years, by the addition of 

 several species already kuown in Britain ; and it has been thought useful to 

 include in this communication a brief report on the state of our knowledge 

 of the occurrence of these animals in this country. Finally, a classified list 

 of the British and Irish species is given ; and this list has been marked so as 

 to show at a glance the respective faunas of the two countries. 



1. A NEW SPECIES OF ChELIFER. 



In 1913, an opportunity occurred for the examination of abundant 

 material of the false-scorpion here distinguished as Chelifer {Chernes) Powelli. 

 A large number of specimens had then recently been collected by Mr. H. L.
