1905. Notes. 247
A new Liverwort from Ireland
In the journal of Botany for October, Mr. W. H. Pearson describes and
figures a new species of Flagiochila, which he names P. killarniensis, which was discovered by him last June growing on a moss-covered stone close to Torc Cascade, Killarney.
Artemisia maritima-a new station for Co. Dublin.
In July last this rare species turned up quite unexpectedly in a new
County Dublin station, at the shore end of the Cardy Rocks, about a
mile north of Balbriggan, where it grows in sorte quanltity on the top of
a low reef hardly five feet above tide mark. I had passed within a
stone's throw of this station fully half a dozen times whlle engaged in a
botanical survey of the county without noticilng the plant, and should
have passed it again on this occasion had my eye not been caught by a
single tall budding spike. The Arternisia is admirably protected froimi
discovery by association here with a conmnion lichen, closely resemlbling
it both in colour and in stature.

ZOOLOGY.
Irish Fresh-water Sponges.
Dr. Hanitsch, in his paper on L The Freshwater Sponges of Ireland" (Irish Nat., iv., I895), nioticed that Euspongulla lacusv is hiad been found in Camlough River, Co. Armagh, and at Killakeen, Co. Cavan; and iletero meyenta Ryderi in Lough Doon, Co. Kerry. Since then, specimens of these sponges have been received at the Dublini Museum fromll various parts of the country.
Euspongidla at ustris lias beenl found in the following localities -Loug,l Neagh; Woodburu, Co. Antrim; Portarliugton; tough Carrowbeg, Co Mayo; and Lough Corrib. This sponge thus seems to be as widely distributed throughout the country as Dr. Hanitsch predicted. Hetero rneyenia Ryderi lhas been found in Lough Eagher, Co. Keiry (see Irish
Nat., viii., 1899, P. 2I7), and Loughs Fee anld Ballynakill, Co. Galway.

Psithyrus campestris in Co. Carlow.
Referring to Mr. Halbert's note on the above (sup a, pp. I98 9), 1 have
taken this Psi/hyrus here in considerable jumtibers. I hiave also taken a
few females of P. vesttalis, whicli seems to be iniuch less common here.
