ISOPODS. 

 BY R. F. SCHARFP, PH.D. 



The large grey Oniscus ascllus is exceedingly abundant under 

 logs of wood, under stones, and under all kinds of refuse. The 

 very minute red woodlouse {TricJioniscus pusillus) is common 

 in Clonbrock wood under moss, and indeed everywhere where 

 there is sufficient dampness to suit its comfort. Philoscia 

 m7iscor76m, which swiftly darts about among the twigs and moss, 

 and Porrcllio scaber frequent much drier localities. All these 

 are species which occur in almost all parts of Ireland, and, 

 except Metoponorthus pruinosus^n.Q> rare woodlice were observed. 

 The latter occurs at Clonbrock only among garden refuse, 

 and even there it is very scarce. 



The most striking feature is the absence of the * Pill Wood- 

 louse '(^rwa^////^/z^;;2 vidgare), a species which is so abundantly 

 met with around Dublin. 



SPIDERS. 

 BY GKORGK H. CARPKNTKR, B.SC 



Unabi^E to join the Clonbrock collecting-party myself, I looked 

 forward eagerly to the examination of the spiders and harvest- 

 men which Scharff and Halbert were so good as to secure for 

 me from that now famous locality. The result proves most 

 gratifying, as the thirty-three species of spiders collected 

 comprise five which I had not before identified from any part 

 of Ireland. Several of the other species are now recorded as 

 Irish for the first time. This collection must represent but a 

 small fraction of the spider-fauna of the district, and many 

 other novelties and rarities doubtless await discovery there. 



I had some hopes that traces oi Atypus—OMX only British 

 genus of the Aviculariidcs, whose nest has recently been dis- 

 covered in King's Co.' — might have been found at Clonbrock. 

 These expectations, however, were disappointed ; nor was a 

 species of the Dysderidce to be found in the collection, though 

 several probably occur in the district. The large family of 

 the DrassidcE was represented only by the ubiquitous Clubiona 

 reclusa, Cb., and the more interesting Anyphcsna acce?iftiata, 

 Wick., a species not included in Workman's list^, but collected
