British Land Isopod'f. 371 



Genus AiiMADiLLiDiUM, Brandt. 



ArmadiUidiuin vulgare (Latreille), 



Dr. Scharff, in his paper on " The Irish Woocllice " {' Irish 

 Naturalist,' vol. iii. 189i), 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 Galway 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 

 Dr. 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), which is of 

 about an acre in extent, 1 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. 



Garden at Dublin (Dr. Kinahan's) : — Trichoniscus pusillus 

 {^Philourgria celer) ; Oniscus asellus [0. murarius and/bssor) ; 

 Fhiloscia muscorum ; Aletoponorthus pruinosus {Porcellio 

 pruinosus) ; Metoponorthus cingendus [Porcellio cingendus) ; 

 Porcellio scaber, Uevis, pictus, and dilatatus; Cijlisticus coii^ 

 VlXus [Porcellio armadUloides) ; Armadillidium vuhjare.
