i9i8. Workmax. — Tlie Migration of Woodcock. 95 



(i) Woodcock that are hatched out and remain in this 

 locality sometimes for years, that is " Resident 

 Birds." 



(2) Woodcock that are hatched out in this locality and 



that migrate in a southerly direction. 



(3) Woodcock that arrive from the north during the 



winter months. 

 I trust the above notes on Captain Douglas's valuable 

 paper may be of interest, and we Irish ornithologists will 

 welcome particulars of a further instalment of this Woodcock 

 experiment. I may here say that Captain Douglas in a 

 letter to me, hopes that others who have shootings both 

 in Ireland and other parts of Great Britain would follow 

 Col. Ashley's example so that more information could be 

 collected regarding the migration habits of Woodcock.

BOTANY. 



Cardamine amara in East Tyrone. 



In addition to Mr. Greer's records for Cardamine amara in East Tyrone 

 (/. Nat. December, 1917, vol. xxvi., p. 196) it might be well to note that 

 on the excursion of the Belfast Naturalists' Field Club to the Torrent River 

 valley on 3rd June, 1916, the plant was found near the aqueduct which 

 carries the canal over the Torrent River.

Arenaria ciliata. 



In the Nyt Magazin for N aturvidenskaberne , 1917, pp. 215-225, Drs. 

 Ostenfeld and Dahl discuss the northern segregates of this species, which 

 in the British Isles is found only on the Ben Bulben range in Ireland 

 and (as A. norvegica of British floras) in Shetland. They divide the 

 northern forms into three sub-species : — i. hibernica, {A. ciliata of British 

 authors), the Irish plant ; 2. pseudofrigida, occurring in Norway, 

 Lapland, arctic Russia, Spitsbergen, and Novaja Semlia ; and norvegica 

 {A. norvegica Gunnerus and British authors), found in Norway, Sweden, 

 Shetland, Iceland, Greenland, EUesmereland, Labrador ? and Canada,
