72 The I) ish Naturalist. April, 



also for the Silver-washed Butterfly [Aroyjinis paphia)^ which 

 seemed abundant, and came sailing into the sunlight of the 

 glades with much grace. Finally on August 28th the all-day 

 coach journe,v to Killarney was undertaken ; but only for a 

 stay of three days, two devoted to Mangerton Mountain and 

 one to the lake-margins and woods between the Muckross 

 Hotels and Galwav's Bridge. 



For Mangerton on both occasions I took the well-known 

 way to the Devil's Punch-bowl, and did not venture much 

 beyond this lough on the first day because of the great 

 cloud which clung to the mountain, drenching it with a heavy 

 moisture and obscuring everything from view. There were, 

 however, partial clearances; and it was interesting to see the 

 slugs creeping out. At about 2,300 feet Avion ater was in 

 characteristic mountain dress with the whole of the foot- 

 sole as well as every other part of the bod}' entirely 

 black. At about the same height too, the small dark moun- 

 tain form of Limax arbo7'iim appeared, creeping in numbers 

 on the bare rocks ; and some individuals, like those found by 

 Dr. Scharff on Caher,^ were quite unicolorous above and 

 almost or quite black. Next day was beautiful!}^ fine, with no 

 cloitd and only a moderate wind ; and going now over the 

 Punch bowl and by a small part of the 1,000 feet precipices of 

 the Horse's Glen- — whence one looks down on the black 

 lyOughs Erhogh and Managh — I was able to spend some time 

 on the top of Mangerton, where there is a considerable summit- 

 plateau, with a heav}' covering of peat in part washed awa\^ 

 and leaving exposed vast quantities of small flattish rock- 

 flakes. Under these flakes, that is to say at about 2,750 feet, 

 good num])ers of Arthropods were found : a centipede {Litho- 

 bius, probably L. varieoatus) ; a big-bodied harvestman, 

 Olioo/ophus alpinus ; a staphylinid-beetle, Oucdius 

 ujubrinusi ; and crowds of carabids ; Ncbria Gyllenhalii. 

 Nebria brri'icollis^ L cist us ni/cscenSy J\itrob?is assi7?iilis, 

 Trcchus obtusus, and Notiophilus aquaticus. Spiders too were 

 numerous in individuals; but I found only three species, 

 named by Dr. Jackson as Robert us lividus, Maerargus abno)mis_ 

 and Hilaira inontigena — PedanostetJius lividns, Tnicticus abiior- 

 mis, and 'J)uetieus uiontioDia of familiar nomenclature — 

 the last new to the Irish list. On may see from here, 

 Carrantuohill rising out of the Reeks ; and it may be 

 noted that of the six animals found bv Dr. SchartT and
