I9I7- Notes. 171 



Equisetum litorale. 



Mr. Waddell points out to me that in my account of this plant in last 

 number I omitted reference to a Scottish record by W. A. Shoolbred, 

 published in the Report of the Botanical Exchange Club for 191 3 (banks 

 of Lough Tummel, Perthshire). The plant is thus known at present 

 from one station in each of the three kingdoms — England, Scotland, and 

 Ireland.

Mossy Saxifrages. 



In the Journal of Botany for June, Rev. E. S. Marshall discusses 

 critically some of the Mossy Saxifrages of the British Isles, on which 

 he has been at work for some time. He finds that S. incurvifolia D.Don 

 (for synonyms of this and the other plants mentioned the paper must be 

 consulted) is endemic in Ireland, occurring in Kerry and on the Twelve 

 Bens. The name S. groenlandica must disappear from our lists. 5. 

 Slernbergii Willd. from Brandon in Kerry and North Clare is the true 

 plant. It is not known in Great Britain. S. rosacea Moench is the 

 correct name for the plant known as S. decipiens Ehrh. (a nomen nudum). 

 Mr. Marshall confirms it from Kerry, Twelve Bens and Clare Island, 

 the only other Britannic station being in Wales. 5. hirta Smith (not of 

 Haworth, whose name disappears) is accredited to Kerry, Clare, and 

 Tipperary. Waterford and Donegal are added with a query. True 

 5. hypnoides L. is also Irish. For further notes Mr. Marshall's interesting 

 paper should be consulted. 



ZOOLOGY. 



Happy Roscommon ! 



A correspondent sends us the following paragraph from a recent issue 

 of the Daily Mail : — 



" Rare Butterflies in Flocks. — A remarkable spectacle may be seen 

 now in County Roscommon and, indeed, throughout Central Ireland, 

 where myriads of rare and beautiful lepidoptera are disporting themselves. 

 The lovely peacock butterfly is the most numerous, and clusters of this 

 species may be seen on a single plant. They can be taken in the hand 

 or plucked like fruit from a tree. The swallow-tail, red admiral, painted 

 lady, and many other varieties are here in profusion. It is a record 

 occasion for collectors." 



Such enlightenment on an unexpected addition to the Irish fauna 

 will doubtless be received by naturalists in this country with the docility 

 due to the universal knowledge possessed by all writers in our daily 

 contemporary,
