BOTANY. 

 Cladlum Jamalccnsc and Carex riparia In Co. Down. 



A winter's da}^ ten years ago, I spent in going over the then partially 

 constructed line from Downpatrick to Killough, by invitation of my 

 friend, Leonard Bell, C.E., Resident Engineer. At the point where the 

 foundations of the bridge over the Killough-road were pegged out, the 

 leaves of a large sedge were noticed, which I could not identify at the 

 time ; and driving back to Downpatrick in the twilight, another 

 unfamiliar cyperaceous plant was seen forming a dense grove in the 

 centre of a marsh by the roadside, three miles from Killough. "When 

 cycling last Easter I revisited these spots. The plant at the former place 

 I now recognized as Carex riparia^ and I observed it growing abundantly 

 in ditches by the railway around Killough distant signal. The second 

 plant was also duly refound, and turns out to be Cladinnijamaicense. Both 

 of these species are to be reckoned among the rare plants of Co. Down. 

 Cladium had not been seen in the county for a century till Mr. Stewart 

 and I rediscovered its only station near Castlewellan, and I subsequently 

 found it near Strangford {I.N. vi., 219). C. riparia had four previous 

 records :—Gillhal! (Corry); Lough Neagh, 1838 (Hyndman); near 

 Belfast, 1806 [extinct] ; and Lough Neagh, 1810 [close to Hyndmau's 

 Station], Templeton.

ZOOLOGY. 



CRUSTACEA. 



Trichonlscus vividus at Cappag^h. 



When on a visit to Mr. Ussher's beautiful demesne at Cappagh, Co. 

 Waterford, last summer I met with Trichoniscus vividus in large numbers. 

 This rare woodlouse occurred under fallen leaves and sticks close to the 

 shores of an artificial lake. It was first recorded from Portlaw, Co. 

 Waterford, by the late Prof. Kinahan. I subsequently' took it at Borris, 

 Co. Carlow {Irish Nat. vol. iv., p. 319) so that Cappagh is the third locality in 

 Ireland. It has never been found in Great Britain, and on the Continent 

 it only occurs in the Pyrenees.
