November 4th, 1878. 
Charles Bailey, Esq., President of the Section, in the 
Chair. 
Mr. Plant, F.G.S., exhibited as additions to the Fauna of 
Cymmeran Bay, Anglesea, fine specimens of the Portuguese 
Man of War (Physalia pelagica), which came in with a S.W. 
gale, accompanied by many specimens of the Vellella. 
Mr. J. Cosmo Melvill, F.L.S., read an account of three 
visits paid by him to the Breidden Hills, Montgomeryshire, 
North Wales, in May, June, and July, 1877. 
The Breidden hills form an isolated range in the extreme 
north-east corner of the county, where it joins Salop, about 
ten or twelve miles due west of Shrewsbury, and three miles 
distant from Welshpool, from which town the best view of 
them is obtained, and where they are the most conspicuous 
objects to the north-east. 
The rocks are Lower Silurian, igneous and crystalline. 
Moel-y-Golfa, the southernmost peak, attaining an altitude 
of nearly 1500 feet, is formed of felspathic Trap and Ash; 
while Craig Breidden, the northernmost summit, and the 
intermediate hill, are both of Igneous Greenstone. 
The county of Montgomery being one of the nine men- 
tioned by Mr. Hewett C. Watson in his latest work — 
“Topographical Botany” — as being completely unworked, 
so far as Botanical data are concerned, renders any list of 
the plants interesting. Among a total of over 800 observed, 
the following catalogue represents the rarer species only : 
Ranunculus parviflorus (L.) 
Meconopsis Camhrica (Vig.) 
Corydalis claviculata (D. L.) 
Fumaria Borgei (Sm.)
