SOME LAND ISOPODS FROM COUNTY GAWAY. 



BY CHAS. CHILTON, D.SC, F.L.S. 



I have lately been going over the terrestrial Isopoda in 

 Professor D'Arcy W. Thompson's collections in University 

 College, Dundee. Among them are several collected at 

 various times from two localities in Co. Gal way, i.e., at 

 Galway itself and at Roundstone. As some of the species do 

 not appear to have been previously recorded from this part of 

 Ireland, it may, perhaps, be worth while giving the list of 

 species here : — 



LIgia oceanlca, Linn.— from Galway and Roundstone. 



Trichoniscus pusillus, Brandt.— Galway. 



Onlscus asellus, Linn.- Galway and Roundstone, 



Philoscia muscorum, Scopoli— Galway and Roundstone. 



Porcellio scaber, Latr. — Galway and Roundstone. 



Porcellio dilatatus, Brandt. — Many specimens from Galway and 



Roundstone. This species appears common in Galway, though 



hitherto recorded in Ireland only from Dublin (see Scharff, Irish 



Naturalist, VIII., p. 60). 

 Porcellio laevis, Latr. — Several specimens from Galway. Apparently 



this species was previously recorded only from Dublin, in Ireland, 



though like the preceding species it is very widely distributed over 



other parts of the globe. 

 Porcellio pictus, Brandt.— One specimen from Galway. 

 Metoponorthus pruinosus, Brandt — Two imperfect specimens 



from Galway. 



It is perhaps worthy of note that the collection contained 

 no specimens of Aimadillidium vulgare, Latr., since Scharff 

 {Irish Naturalist, v., p. 225) has drawn attention to its 

 apparent absence at Clonbrock, Co. Galway, and has con- 

 trasted this with its abundance at Dublin. It is, however, not 

 safe to attach very much importance to negative evidence of 

 this kind.
