3. On the state of our knowledge of the occurrence of False- 

 Scorpions IN Ireland. 



These animals have received attention from time to time from several 

 naturalists in Ireland. Specimens have been collected, for instance, on 

 various trips organized by the Fauna and Flora Committee of this Academy, 

 and these specimens have found a home in the National Museum in Dublin. 

 Others have been brought to meetings of the Dublin Microscopical Club, and, 

 in some cases, have been placed in the same Museum. For several years past, 

 moreover, they have been searched for on the excursions of the Belfast 

 Naturalists' Field Club; and, in particular, Mr. Nevin H. Foster, M.R.I.A., 

 who has had a large share in the organization of those excursions, has 

 collected these animals with enthusiasm in many parts of the country. As 



1 Ellingsen (7) has mentioned a Chthonius (Italian specimens) " characterized by the 

 very dense row of small teeth on the fixed linger of the palps " ; he referred it to 

 CMh. orthodactylus (Leach), but incorrectly ; and it is possible that his animal was 

 identical with ours ; on Chth. orthodactyhis (Leach) and the specimens of Chthonius 

 (including the type of this species) in Leach's collection in the British Museum, 

 cf. Kew (20).
