PEOCEEDIXGS OE SOCIETIES, 
Polyzoa overhanging every nook and cranny, which were lined with a 
Balanus not found in Dublin, as far as my knowledge goes-and, to make 
the scene more striking in every sense, the rock bored on every side 
by colonies of Saxicava rugosa , all contributing their share to the invo¬ 
luntary shower-bath which the adventurous explorer was compelled to 
undergo in his researches after the treasures of this shore. I regretted 
that the short time at my disposal precluded my examining more fully 
the species found here. Idoteas were rare as contrasted with Dublin; 
there were but few pools suited for them. I met Dexamine spinosa, 
Gammarus 'locusta, Amphitoe littorina , in abundance. 
Accompanied by my host, I took a short trip into Cornwall, as far as 
Polperro, passing through Millbrook, Craft’s Hole, and Looe, on our way. 
Many features of the Botany were remarkably striking. The im¬ 
mense profusion of Asplenium Adiantum nigrum , which, interspersed 
with Lophodium affinis and Scolopendrium vulgare, completely swathe 
the steep hedge-rows of the district, unlike anything I had ever seen in 
Ireland, except in the county of "Waterford. The profusion of plants, 
either unknown as indigenous in Ireland, or else extremely rare, such 
as the lesser Dodder, which purpled the furze near Polperro; the com¬ 
mon parsley, which grows abundantly in the town itself; the purple 
orchis ( 0 . mascula), which abounded along the road side; the dog mer¬ 
cury ; several species of Gralliacese, and many other plants which had not 
as yet flowered,—made me regret I had not more time to examine the 
quaint old hollow lanes of this interesting county. 
Hear Polperro, facing the sea, just outside the town, I met Asple¬ 
nium lanceolatum growing in great abundance; its mode of vernation 
very distinct from that of its ally. A. Adiantum nigrum, A . Ruta mu- 
raria, A. trichomane, A. marinum, L. multiflora , L. Feenesecii, and Ath. 
Filix fcemina, were all abundant. Hear Millbrook, on the top of a wall, 
was a large mass of the sinuated form of jPolypodium vulgare , as strongly 
marked in its characters as the specimen first described from the Dargle, 
county of Wicklow. 
We had not passed far on our journey before a dead adder on the 
road reminded us that we were within the range of the Germanic spe¬ 
cies of Yertebrates, a fact which the numerous mole earths ridging the 
pastures and corn-fields on every side of us, and the numbers of black¬ 
caps and redstarts singing and flying about, also confirmed. We did 
not see any snakes or other reptiles, except one viviparous lizard. 
The chief object of our trip was for the purpose of examining the 
collection of the father of Cornish zoology, Dr. Jonathan Couch, P.L. S. 
He liberally allowed me to examine an unequalled series of drawings of the 
fishes of the coast, many of which are unique. He also showed us draw¬ 
ings of many rare Crustacea which have passed through his hands, and 
accompanied us to the house of a most enthusiastic zoological collector, 
Mr. William Loughrin, on whom I would strongly recommend every zoo¬ 
logist who may visit this locale to call. Through him, in addition to 
much valuable information, I was enabled to obtain some very rare 
Crustacea, such as Portunus longipes, &c., which have hitherto only
