B. B. Woodivard — Drift, etc., Neu-quay, Cornwall. 



Except for the presence of Helicella barhara and the absence of 

 Jaminia cylindracea, the fauna bears a resemblance to that found 

 at Q,. The former species may indeed be only adventitious, for the 

 mollusc lives on the spot and has a quaint habit of rolling down into 

 places where it has no business. 



On the rocks below, traces of the coarse pebble beach, but no 

 indurated sands, were observed. 



Retracing one's steps southwards past the Lifeboat House and going 

 down the eastern side of the headland, the quarry (U) over Seal Hole 

 is reached. Here a foot or so of ' head ' is covered by a like amount 

 of hill- wash-dune with .shells, including a stray Helix nemoralis. 



At the south end of the quarry where the path leads down (V) 

 another hill-wash-dune is cut into. This contains a few land shells of 

 the species most characteristic of the upper series (see table, p. 85). 



Descending to the base of the cove, the old marine platform is found 

 exposed with the coarse pebble beach resting on it, while projecting 

 through the talus of tumbled top soil that curtains the steep slope, 

 masses of the indurated sands are seen, and round the corner of the 

 south end of this section a big mass of these sands showing current 

 bedding is visible, stacked between two reefs of killas, in a position 

 impossible for a blown sand to assume (Fig. 2). 



Fig. 2. — Diagrammatic sketch of the south end of the Eaised Beach by the Seal 

 Hole, k, killas, rising to near the surface at a, where it is overlain by 

 a hill-wash-dune, b, b, denuded masses of the indurated marine sands, 

 resting to the right on the remains of the coarse pebble beach. 

 c, curtain-like talus of top soil. 



Judging from the species of shells found in the base of the talus 

 (see table, p. 84), the Helix nemoralis zone would seem to have been 

 represented on the spot. 



No further sections were noted till the clitf to the east of the 

 Atlantic Hotel by Pigeon Cove was reached. On the north side of 

 the Cove (W) the old platform is some 15 feet above the sea with the 

 coarse pebble bed resting on it, capped by about 15 feet of indurated 

 sands. Above these, again, there is a very coarse, hard, solid breccia, 

 2-3 feet thick, which seems to have escaped the notice of previous 

 observers. It is quite different from any other rock in the vicinity, 

 though it may be the local equivalent of the ' head.'
