several other similar overflow channels, which had at different periods 

 discharged the surplus waters of a second ice-dammed lake which occupied 

 the valley of the Glonniakecran River. The waters of this Lake Glenma- 

 keeran which were at a higher level than those of Lake Glenshesk, flowed 

 through a deep gorge in the solid rock of the district and which is now 

 streamless, into Lake Glenshesk, and thence by the overflow channel 

 first mentioned, into the valley of the Bush River at Armoy. Several 

 terraces of gravel in Glenmakeeran were also pointed out, and it was 

 shown that these corresponded respectively to the levels of three channels 

 which successively acted as overflows for the lake, it being explained 

 that the terraces were deltas formed in the lake by inflowing streams, 

 each tlclta assuming the level of the waters at the time of its formation.

Two Plants new to Ireland. 



During the recent visit of the International I'hytogcographical Ex- 

 cursion to Ireland, where they were so ably conducted by Mr. R. LI. Praeger, 

 Dr. Ostenfeld and myself independently found the water-lily Castalia 

 Candida (Presl.) (= Nymphea Candida, Presl,) in two loughs near Craigga- 

 more, and also near Roundstone, Co. Galway. Dr. Ostenfeld had previously 

 shewed me the plant in Perthshire, near Dunkeld. At Killarney I was 

 fortunate enough to meet with Viola epipsila Lideb, only recently added 

 to the British flora, the writer having gathered it in Berks and South 

 Devon. Further details of both species will follow. In Cornwall Mr. P. 

 Williams shewed the members the hybrid heath described as Erica cinerea 

 X E. vagans {Journ. Bot., 334, 1910) ; but an examination of it in the fresh 

 state convinced me that the determination was not correct, so in answer 

 to my request, Mr. Williams kindly motored Dr. Graebner and Dr. 

 Schroetcr over to the native habitat, when a close examination showed that 

 although its appearance recalled E. Mackayi, yet the ovary was hairy, 

 and both the foreign specialists agreed with me in considering it to be 

 Erica Tetralix x E. vagans, both of which species grow in the vicinity.
