lity in the Biitisii Isles is in Carnarvon, nearly a degree north of the 

 present habitat. In Ireland, I am not positively aware of its occnr- 

 ring elsewhere south of Dublin Bay. In this stream, and along the 

 northern shore of the lake, ocavLYredL Potainogeton crisjnis, F.perfoliatus, 

 P. lieteropliyllus, P. 'pectinatm, and Myrioxjhylluni S2)icatum. Ramm- 

 culus laudotii was also abundant, and about the middle of the lake 

 occurred Rumex hydrolapathum, and in heavy marshes at its south- 

 west end were Carex imniculata, Nymplima, alba, Sium auyustifolimn, 

 Selosciadium repens, Veronica scutellata, Carex teretiuscida, C. limosa, 

 and C. pidicaris. 



On the following day, July 5th, I traversed the mountains, Benooskey, 

 Slievenagower, Slievenalecka, Slieveanea, and Connor Hill to Dingle. 

 Benooskey is 2715 feet, and reaches to alpine vegetation. The two 

 commonest iond fide alpine species in Ireland occur fi-om 300 feet 

 below the summit upwards. These are Salix herhacea and Carex 

 rigida. Armeria also occurs, and it is always surprising to meet 

 this species at the summit and at the base of sea-coast mountains while 

 it does not occupy the middle distance. Slievemore in Achill gives 

 a remarkable instance of tliis. Saxifraya stellaris and Sedum rhodiola 

 accompanied the true alpines, and in this latitude they nearly deserve 

 the same appellation. Other interesting species met with to-day were 

 Pinyuicida grandiflora, Lobelia dortmanna, Isoefes lacustris, Carex fidva, 

 Saxifraya iimbrosa, and S. yeum. The altitudinal particulars will be 

 given subsequently. The district gone over to-day was varied and 

 interesting, and many of the glens and lake shores would repay more 

 elaborate search. I crossed habitats of Xillarney fern and Sibthorpia, 

 but my labours were chiefly devoted to the higher ground. Towards 

 night I sighted Dingle, and was fain to look for the hotel. Thinking 

 I could telegraph to Castlegregory, I descended to the town, which 

 looked so tempting in its lake-like bay. I had to remain the night, 

 however, without sending word to my hospitable landlady, to the no 

 small alann of the Castlegregorians. 



July 6th. — "Walked to Connor Hill, and thence along the Brandon 

 ridge by Beenduif, Ballysitteragh, Gearhane, and Brandon Peak to 

 the summit. About a mile beyond the summit I descended by two 

 small tams into the head of the Owenafeana valley, and crossing its 

 southern side made my way down to Cloghane, where I arranged 

 about accommodation, and walked into Castlegregory. Remembering 

 the fi'equent detours and climbing bouts, this was a severe day's work. 

 At Beenabrock, and afterwards, I gathered Salix herlacea, Saxifraya 

 stellaris, and Sedum rhodiola. Ai'meria also occurred in many places 

 as at Brandon Peak, which is south of the summit, and nearly 400 

 feet lower than Brandon. The alpine plants on this chain occiar on 

 the eastern side of its upper ridges. After Brandon Peak, I soon met 

 with Cystop)teris frayilis and Polystichnm lonchitis, the latter very spar- 

 ingly. A fine range of cliiis commences here ; and keeping a couple 

 of hundred feet below the crest I found Oxyria reniformis, Alchemilla 

 alpina, and Asplenium viride. Aira cmspitom was the nearest thing to
