Mr. J. N, Halbert, in June, 1896, are the only examples yet found 

 in Ireland. It is a very rare species in Great Britain (Dorset, North 

 "Wales), as also on the Continent, where it has been found in northern 

 and eastern France, Switzerland (where it inhabits high mountain 

 pastures), Germany, Austria, Tyrol, Bohemia, and northern Hungary. 

 It also occurs in North America. 



Cornicularia unicornis (Cb.). 



Walchenaera, unicornis, Bl. (Spid. G. B. I.). 



Leinster. 



Two females of this rare species were taken at Portmarnock, 

 county of Dublin, in June, 1895, by Mr. J. N. Halbert. Widely 

 distributed in England (Dorset — Northumberland), it has occurred 

 abroad in Trance, Sweden, Germany, and Austria. 



Cornicularia cuspiclata, Bl. 



WalcJcenaera cuspidata, Bl. (Spid. G. B. I.). 



Munster. 



An adult male, which I took at Killarney in Novembei', 1893, 

 when collecting for the Eoyal Irish Academy Flora and Fauna Com- 

 mittee, is the only Irish example of this spider which I have yet 

 seen. It is a rare species in Great Britain (Dorset, North "Wales, 

 Edinburgh). On the Continent it is found in Denmark, northern and 

 eastern France, Belgium, Germany, Switzerland, and northern- 

 Hungary ; it is also found in Kamtschatka. 



Typhoclirestus dorsuosus (Cb.). 



T. diyitatus, Carpenter and Evans (1894). 



Leinster. 



A male and female of this very rare spider were taken at Laytown,. 

 on the coast of the county of Meath, in September, 1897, by Mr. J. N. 

 Halbert. Its discovery as a British species was made only four years 

 ago, when Mr. Evans and I recorded specimens from the shores of 

 the Forth, near Edinburgh, under the name of T. digitatus. Mr. 

 Cambridge has since pointed out to us that our specimens are really. 

 referable to the closely allied T. dorsuosus, also described by him. 

 On the Continent this spider has occurred only in southern France 

 and in Holland.
