LICHENOLOGICAL MEMORABILIA. No. 10. 
By the Rev. W. A. Leighton, B.A., Camb., F.L.S., F.B.S.Ed., &c. 
On the Lichens of Fishguard, FemhroTceshire. 
Fishguard is a small town on the north coast of Pembrokeshire, 
midway between Cardigan and St. David’s, distant from each about 
16 miles. It consists of an upper and lower town ; the upper 
placed on a lofty headland of Llandeilo slates, having the strata 
almost vertically uplifted. This formation encompasses the entire 
south side of Fishguard Harbour and Goodwick Bay, and forms 
also the southern bank of the' river Gwaine, a celebrated trout 
stream, which flows many miles through a finely wooded valley 
into Fishguard Harbour. At the base of this abrupt headland lies 
the lower town surrounding the small sheltered Harbour, whose 
opposite side forms another headland of metamorphosed Caradoc 
Sandstone, called Fort Hill, from a ruined fort erected in 1797 
after the landing of the French. About a mile to the west of 
Fishguard, and on the lower level with Fishguard Harbour, is the 
little village of Goodwick, with its beautiful sandy beach and 
magnificent bay lying N.E. and S.W., and opening into Cardigan 
Bay. This picturesque village nestles at the base (with south 
aspect) of Pen Cow, the lofty extremity of a range of low hills of 
Caradoc Sandstone, which extends as far as St. David’s, the summit 
broken at intervals into isolated protruded masses of rocks. This 
ridge skirts the north side of Goodwick Bay, whilst the south is 
surrounded by the Llandeilo Slates of Fishguard, and the Caradoc 
Sandstone of Fort Hill, and the remarkable headland of Dinas 
Head. Fishguard Harbour opens at right angles to Goodwick 
Bay. A fortnight in September, 1876, spent in this picturesque 
locality not only invigorated health with its bracing air and fresh 
breezes, but afforded, especially on the Llandeilo Slates, a plentiful 
supply of Lichens, many rare, some new, and all interesting, as 
extending our knowledge of the distribution of lichens over our 
islands. I venture, therefore, to send you the following enu- 
meration : — 
Sixosiphon. — Stone walls on River Gwaine, near Fishguard. 
Lichina confinis. Ag. — Goodwick Bay.
