ZOOLOGY. 



Armadillidium vulg^are. 



The distribution of Armadillidium vulgare Latreille in Ireland has more 

 than once been commented upon. This Woodlouse has not been found 

 north of a line drawn across Ireland from Gal way to Larne, and but for 

 two localities in Armagh and Antrim the eastern terminus of this line could 

 have been placed many miles further south. In Munster it is not uncom- 

 mon, except in South and North Kerry, where it has not yet been found. 

 It is very common throughout Leinster, though still uniecorded from 

 Longford. Except for two localities in S.E. Galway, it has not been found 

 in Connaught. From Ulster it was long believed to have been absent, 

 but closer search has been rewarded by the finding of a few specimens at 

 Carrickmacross and at Navan Fo'-t and Umgola (both near Armagh City), 

 in the counties of Monaghan and Armagh respectively — each of these 

 localities being on the limestone. A large colony was discov(w-ed at 

 Magheramorne, Co. Antrim, by A. W. Stelfox. Here it is possible it was 

 artificially introduced by a ship discharging ballast, as it exists in company 

 with some species of molluslcs and plants not native in this district. In 

 Co. Down it resides in small numbers in the southern part of the count}' — ■ 

 Ari glass, Killough, Portaferry, Downpatrick and Newry, though appa- 

 rently not at Annalong or Kilkeel. Recently I discovered a very numerous 

 colony on the bank of the river Bann at Laurencetown, and it may be 

 mentioned that this locality is less than a mile from Seapatrick, where
