Locker Beck, a small tributary of the Wheal, the principal stream of 

 the dale. In the same wood Trientalis europaea occurred plentifully. 

 The elevation, as nearly as I can calculate, will be about one thou- 

 sand feet above the level of the sea.

Occurrence of Rare Ferns in the Snowdon District. 

 By Edward Newman. 



Woodsia Ilvensis. This fern has appeared in unusual abundance 

 during the past season at the old station on a rock above Llyn-y-Cwn. 

 A correspondent writes me for my own information, that as many as 

 about a hundred plants are visible ; fortunately, however, nearly the 

 whole of them are inaccessible, and cannot possibly be obtained with- 

 out the assistance of a ladder. 



Woodsia alpina. This fern has occurred in smaller quantities than 

 the above at the old station of Clogwyn-y-Garnedd : two botanists 

 have kindly handed me this information. 



Asplenium germanicum. Two plants of this species have been 

 found in the previously recorded locality between Llanrwst and Capel 

 Cerig. I believe it is properly called Bwlch-y-Rhyn, but the spell- 

 ing of Welsh names seems not to be governed by any fixed law, but 

 to be optional with the tourist. Would it not be wise as well as con- 

 venient to adopt the spelling of the Ordnance Survey, thus reducing 

 topographical nomenclature to a fixity, rather than leaving it as at 

 present a mere matter of taste ? 



Asplenium septentrionale. In twenty localities near Llanrwst, or 

 between that town and Capel Cerig, more particularly in Bwlch-y- 

 Rhyn. 



Polystichum Lonchitis. Cwm Idwell and Clogwyn-y-Garnedd, not 

 very sparingly in either locality.
