Carpenter — A Lid of the Spiders of Ireland. 177 



October, January, April, and May. It seems generally distributed, 

 though scarce in Great Britain, as far north as Edinburgh at least. 

 On the Continent it is generally distributed in France (including 

 Corsica), Germany, Austria, and Hungary ; but apparently is not 

 found in Sweden. It is recorded from Kamtschatka.

Females of this spider were obtained, and recorded (1896) by Mr. 

 Jameson, from the caves of Coolarkin and Marble Arch, near Ennis- 

 killen, county of Fermanagh, when collecting for the R. I, A. Flora 

 and Fauna Committee in July, 1895. It has been found on the Pent- 

 land hills, Scotland ; in coal-pits in. Durham, in Hertfordshire, and 

 Dorset ; in northern France, and northern Hungary. It is therefore 

 not a typical cave-species like the next. 



Porrhomma my ops ^ Simon. 



Munster. 



This spider inhabits the Mitchelstown Cave in county of Tipperary. 

 The eyes are in all cases more or less degenerate. When visiting the 

 cave in July, 1894, I discovered a male and female, which I described 

 and figured (1895 i.). In the succeeding year, also in July, Mr. Jame- 

 son obtained a number of specimens of both sexes (1896) ; and Mr. 

 G. E. Mason, of London, also took several examples of the spider, 

 which appears not to be uncommon in its underground locality. A 

 single female of P. myops has been taken in Dorset by Mr. Cambridge, 

 and it inhabits the Cave of Espezel, Department of Aude, in southern 

 France. I am disposed to regard Linyphia incerta, Emerton, from 

 the Bat Cave of Kentucky, as identical with the present species, but 

 M. Simon considers that spider to belong to the genus Taranucnus. 



[_Porrho7mna egeria^ Simon, is recorded from Ireland by Eev. 0. P. 

 Cambridge (1895) in error, the specimen which he received from me 

 for examination being Scotch,]
