been taken in the open country. It 

 ■was taken under stones iu the semi- 

 dried-up bed of a mountain stream at 

 Glenade, Co. Leitrim (A.W. S.); and 

 on a railway spoil- bank at Portumna, 

 N. Tipperary (R. LI. P.). It is recorded 

 from several places in England and 

 Scotland, where, as with us, it is 

 commonest in old gardens ("Webb and 

 Sillem). It occurs all over Central 

 and Southern Europe, and in Northern 

 Africa (Algeria) (Budde-Lund).

This minute species was first dis- 

 covered in Ireland in 1908 at Hills- 

 borough, Co. Down (N.H. F.); and a

few days later at Glasnevin, Co. Dublin 

 (J. N. H.). It had probably escaped 

 recognition so long on account of its 

 very great general likeness to T.puullus. 

 This resemblance is more marked in 

 preserved specimens than in life, when 

 its slower movements, greater propor- 

 tional length, and dark dorsal line make 

 it fairly conspicuous. It is usually 

 found in damp situations, decaying 

 boards lying in gardens affording a 

 favourite habitat, whilst we have 

 found it by no means uncommon under 

 deeply embedded stones. Since its first 

 capture it has been found at Dingle, 

 S. Kerry (A. W. S.); Borrisokane, N. 

 Tipperary (R. A. P.); Bagenalstown, 

 Co. Carlow (D. K. P.B.); Carton, 

 (R.J. P.B.), and Hill of Allen 

 (A.W. S.), Co. Kildare; Ferbane, 

 King's Co. (D. R. P. B.); Howth, 

 Co. Dublin (D. R. P. B.); Monaghan 

 (A.W.S.); Bundoran, E. Donegal 

 (N.H.P.); Tory Island, Bunlin, and 

 Doe Castle, W. Donegal (A. W. S. and 

 R. W.) ; Albany, Co, Tyrone (N. H. F.) ; 

 Navan Fort, Co. Armagh (N.H. F.); 

 Dromore and Castle vrellan, Co. Down 

 (N. H. F.) ; Belfast, Sallagh Braes, and 

 Glenariff, Co. Antrim (A. W. S.) ; and 

 Castlerock, Co. Londonderry (N. H. F.). 

 Triclwniscus pygmaeus was first taken 

 in Great Britain by Mr. A. Patience 

 eaily in 1906, and he has since found 

 it to be widely distributed over the 

 Clyde faunal area. The only other 

 localities from which it is recorded 

 in England are Lundy Island 

 (B. F. Cuiumings), !N"ewcastle-on-Tyne, 

 and Kew Gardens (R. S. Bagnall). 

 On the Continent it lias been recognized 

 only iu Norway by its desciiber, Prof. 

 G. 0. Sars.
