222 The Irish Nahira list. November, 



specimen arrests attention. All of the eight individuals lived with me 

 for a fortnight, during which they underwent fantastic changes of form, 

 passing from regular cylinders into slender -stalked cups, and thence into 

 dome-shaped umbrellas as the orange mouth became exserted. 



Gosse, in his account of the species {British Sea Anemones, p. 204), 

 speaks of having seen one specimen protrude from the mouth " a bundle 

 of what appeared to be true Acontia." Undoubted acontia were pro- 

 truded by most of my Bullock specimens eight days after they had been 

 dredged, the acontia issuing not only from the mouth but, in some in- 

 stances, from ruptures in the walls of the column. Magnified 450 diameters 

 these acontia were seen to be crowded with slender cigar-shaped cnidae 

 or thread -cells which under the light pressure of a cover-glass freely dis- 

 charged their ecthoraea or filaments. 



This species has evidently a wide bathymetrical range, from 8 f. at 

 Bullock to 200 f. off the Irish south-west coast. At Plymouth, Miss 

 Stephens tells me, it has been dredged in from 14 to 30 f. {Marine Journ. 

 Biol. Assoc, vii., 1904).

Wrens on Migration at the Tuskar Light station. 



In the early hours of Tuesday morning, September 17th, 1912, i.e., 

 between 3.10 a.m. and dawn, a Wren came up to the lantern of the Tuskar 

 Lighthouse, and was collected by Mr. Glanville, who kindly handed the 

 specimen over to me. At 9.30 a.m. of the same morning I collected 

 another Wren on the rock. At 7.10 a.m. on Tuesday, September 24th, 

 1912, I collected a Wren on the rock, and at 9.30 of the same morning 

 I collected another specimen, also on the rock.

The Greenland Wheatear in Ireland. 



When at the Dundee meeting of the British Association, I had the 

 pleasure of meeting Miss Rintoul and Miss Baxter, who have done such 

 good work at bird-migration on the Isle of May, also Mr. Eagle Clarke, 

 of Edinburgh, and they inform me that the length of wing is the only 

 safe character whereby to distinguish the Greenland Wheatear from the 

 ordinary form which breeds in Great Britain and Ireland, and that all 

 specimens of Saxicola oenanthe with a wing iiieasurem.ent exceeding
