up to near the summit, and is fairly plentiful, bearing on stli August 



both flowers and fruit. The occurrence of the plant is very similar to 



what we find in Derry. There it grows at an elevation of about 1,100 



feet on basaltic rocks which have a northern exposure. It is singular 



that a plant so easily recognised should remain unseen so long. Did 



Templeton inform Mackay of its occurrence on Knock Dhu and yet 



neglect to note it in his journal or his MS. Flora }

[Mr. Stewart's note is of much interest, and supplies what has been 

 wanted with regard to the occurrence of this plant in Co. Antrim — 

 definite particulars as to its habitat and distribution ; and the correction 

 which he makes as to its station — Knock Dhu, not Sallagh Braes— is 

 timely. To ourselves, Mr. Stewart's note is satisfactory as justifying 

 our remark that it was unlikely that so conspicuous a plant could have 

 so long escaped notice at Sallagh Braes, in spite of very positive state- 

 ments to the contrary. Sallagh Braes is well-known ground and our 

 local flora is full of references to the plants which grow there. Knock 

 Dim, on the other hand, is almost unworked, and hardly a plant is 

 recorded from it. — Eds.] 



ZOOLOGY. 



MOLLUSC A 



Hyallnfa excavata In County FermanaiTh. 



Mr. Langham and I recently discovered this rare British species under 

 pine bark in the extensive demesne of Tempo Manor. The wide um- 

 bilicus distinguishes it at once from its nearest relative Hyalinia nitida. 

 It has never been found in any inland county in Ireland before, having 

 only been met with in about half a dozen places on the west and south 

 coasts. In Great Britain it occurs in the extreme south and north and in 

 the south of Scotland. Outside the British Islands it has only been 

 found in a single locality, viz., at Fleusburg in Northern Germany.

CRUSTACEA. 



Cylfsticus convexus In Co. Fermanagfh. 



This extremely rare British woodlouse, the discovery of which in 

 Ireland I announced in the Irish Naturalist^ vol. iii., 1894, occurs in Mr. 

 Langham's demesne of Tempo Manor, near Lisbellaw. I have stated on 

 a former occasion that it had once been taken in England and once in 

 Scotland. It runs with great agility, and when disturbed partially rolls 

 itself up into a ball. It may be recognized by the tip of the tail being of a 

 light yellow colour, whilst the rest of the body is grey. No other species 

 of Cylisticiis has such a wide distribution, for it has been taken in 

 Scandinavia, Germany, France, Austria, Turkej'; audit ranges even into 

 Boreal North America. Almost all the other species of this genus are 

 confined to South-eastern Europe.
