To this list we add Pectunculus glycimeris, and Pecten varius. 

 Purpura lapillus was dee^jly striated, and beautifully marked — 

 the striae banded black and white, or brown and white, alternately. 



V. — PORTPATRICK. 



Driving over to Portpatrick from the placid waters of Loch 

 Ryan, a great change has taken place ; a bold, storm-beaten coast 

 appears; steep cliffs, some rising perpendicularly to a height of 

 130 feet, deeply cut into narrow ravines and gullies, up which the 

 waves rush in great fury, and rebounding at the top, are dashed 

 into clouds of spray. Nestling at the base of these cliffs, where 

 they recede a little back from the sea, lies the town, built to all 

 appearance in an old quarry, a resemblance which the stones 

 hewn out of the rocks, and the excavations made for the harbour 

 works going on, do not lessen. 



A little to the south stands Dunskey Castle on a precipitous 

 cliff 100 feet above the sea, and accessible only by proceeding 

 along the cliffs. Cautiously descending a steep grassy slope, a 

 shingly bay at its base on examination yielded twenty-two species 

 of algae. Then going along the cliffs to the north of the town we 

 descended to a fine sandy bay — Port Murray — at the head of 

 which stands an iron-pillar — the exit of the Irish submarine cable, 

 — and crossing a narrow cliff to the north of this we came to 

 another bay — Port Kale— composed of shingle and fine gravel. 

 On such an exposed coast, where boulders and gravel are con- 

 stantly rolling, shells, algse, and other organisms, are speedily 

 pounded into a fragmentary condition. 



Among the algae washed ashore and scattered on the beach in 

 these bays, we collected thirty-seven species, all common on rocky 

 coasts. Some of the stems of Laminaria digitata were six feet in 

 length, and one and a-half inches in diameter, and very few of 

 them had the fronds attached. 



The following zoophytes were obtained :- 



Sertularia abietina. 



— argentea. 

 Plumularia falcata. 



— cristata. 

 Flustra foliacea. 

 Antennularia antennina. 



E 



Crisia eburnea. 

 Cellepora pumicosa. 

 Eudendriun ramosum. 

 Tabularia indivisa. 

 Laomedea geniculata. 

 Membranipora pilosa.
