British Land Isopoda. 371 



Genus Armadillidium, Brandt. 



ArmadiUidium vulgare (Latrellle). 



Dr. Scharff, in his paper on " The Irish Woodlice " (' Irish 

 Naturalist,' vol. iii. 1894), wrote of this species: — "In Ire- 

 land it is more common in the plains than in the mountains, 

 and it has not been taken on the west coast." Remembering 

 this, when in Galwaj in 1900 I sought for the species where- 

 ever 1 was, but saw nothing of it in the north ; but in the 

 south of the county I met with it in some numbers at 

 Ardrahan.

This is the third addition to our fauna made since my 

 previous paper was published. I have received from 

 13r. Scharff specimens which were found at Sligo. 



Dr. Kinahan, in his first paper on the British Land Isopoda 

 (Nat. Hist. Review, vol. iv. 1857, p. 258), mentioned that 

 twelve out of the fourteen species he then recorded had been 

 found in his garden, not 60 yards square, at Dublin. Gardens, 

 in fact, are especially favourable hunting-grounds for woodlice. 

 In my own here, and even in the part nearest to my house 

 (separated by a fence from a farther garden), Avhich is of 

 about an acre in extent, I have found ten species. It may 

 be of interest to note the woodlice found under similar circum- 

 stances by Dr. Kinahan and myself. I use present nomen- 

 clature and place the names employed by Dr. Kinahan in 

 brackets.
