county of Galway (where I took adults of both sexes in September, 

 1897), Avondale, county of Wicklow (where Mr. Halbert found 

 adults in the same month), and Broadford, county of Clare (where 

 a female was ca^Dtured by Mr. Halbert in June, 1895). It is a rare 

 species in Great Britain (Dorset, JS'orth "Wales, Cumberland), while 

 its continental range resembles that of P. ClercTcii. 



Pachygnatha Pegeerii, Sund. 



Ulster, Connaught, Munster, Leinster. 



One of our commonest and most widespread spiders, ranging from 

 county of Donegal, Antrim (Eathlin Island), and Derry to Wexford, 

 Cork, and Kerry, extending into the south-western peninsulas (Slea 

 Head, Derrynane) ; from Dublin to Achill Island, county of Mayo, 

 and Connemara (Eoundstone, Inish M'Dara, and Leenane). Adults 

 are to be found at all seasons of the year. P. Pegeerii is generally 

 distributed in Great Britain and throughout Europe. 



Tetragnatha extensa (L.). 



Ulster, Connaught, Leinster, Munster. 



This species seems to be widely distributed in Ireland and fairly 

 common. I have localities ranging from the counties of Antrim, Derry, 

 and Donegal, to Skibbereen, county of Cork, and Kenmare, county of 

 Kerry ; from Dublin to Ballymote, county of Sligo, Eecess, county 

 of Galway, and Limerick. Adults and young are to be found from 

 May until September. It occurs throughout Great Britain, and 

 extends from Lapland to the Mediterranean (Spain, south Italy, and 

 Greece), occurring also in northern and central Asia, as well as in 

 IS'orth America (including the Aleutian Isles and Labrador). 



Tetragnatha Solandrii, Scop. 



Ulster, Connaught, Munster, Leinster. 



Evidently much scarcer in Ireland than the preceding form. The 

 only certain localities in Ireland are Londonderry ; Ballymote, county 

 of Sligo; Kenmare, county of Kerry; Berehaven, county of Cork; 

 Blessington, county of Wicklow ; Lucan, county of Dublin. It is 

 generally distributed in Great Britain, and extends on the Continent 

 from central Norway to Italy. 



Tetragnatha ohtusa, Koch. 



Connaught, Munster, Leinster. 



The only localities as yet for this species are Athlone ; Clonbrock,
