NOTES. 



BOTANY. 



Some Cork Plants. 



During a short visit to Cork harbour last summer the following few 



plants were noticed in the neighbourhood by the Rev. E. S. Marshall 



and myself: — Atriplcx Httoralis, Ivinn. —sparingly on Brown Island at the 



back of Great, or Queenstown, Island, Bast Cork. Potcniilla procunibeus, 



Sibth. — frequent about Crosshaven and Currabinuy, Mid Cork. P. subciccia, 



Zimni. (= P. procunibcns X sylvestyis^—y^'xWs. the above, frequent ; while 



Mr. H. W. Pugsley names a Funiaria gathered on Currabinny strand, 



" F. Borcci, Jord., var. seroiina, Clavaud."

ZOOLOGY. 



Paludestrina (Hydrobia) Jenkinsi. 



Mr. J. D. Dean, in the Joional of Conchology. vol. Ji, p. 15, gives some 



interesting notes on the way certain fish in his aquarium behave with 



regard to this species, Carp evidently preferring it to ordinary food ; 



but not so Perch, Roach, or Dace. He also speaks of the statement that 



the mollusc seems to have " taken over " a locality to the exclusion of 



other species of shells, but has heard no reason assigned for this. In 



Ireland we hardly have had time to work out this question. At the 



station where it was first found — little brackish pools on the margin of 



theBann along Portstewart sand-dunes— it certainly lives b}' itself so far. 



That is not the case, however, in a wide shallow drain near Coleraine 



bridge, where it lives with Liniuaia peregra. In the Newry locality (/.TV., 



vol. viii.,p. 271) the latter and Planoi-bis spirorbis are abundant in the drains. 



Recently (on March i) Mr. J. N. Milne turned up plenty oi P. Jenkinsi 



with Aplexa Iiypnorjun, L. peregra and Planorbis spirorbis in a shallow 



drain along the railway that we were examining, quite close to 



Limavady junction. This is a new station for the species, and an 



interesting one; for Mr. Milne, who has worked these drains for man}' 



years, is absolutely certain it was not there three years ago, but is a later 



introduction. It will be worth watching to see how the species behaves 



here. The drain is on the inside of the rail embankment, and we could 



not find it in the one on the outside. About ten days later I made 



careful search for it in many drains and pools, in the intakes along both 



sides of the line between Eglinton and Culmore stations. I did not see a 



trace of the shell alive or dead, and evidently missed the pool near 



Culmore where Mr. Milne got the fine coronated specimens some years 



ago. It is quite possible that the species is still very local here, though 



it is plentiful in the Fojle not far away.
