During the past year I had the pleasure of spending some weeks on the north coast of Cornwall, south of the Camel, examining the rocks exposed in the cliffs and on the foreshores of the various coves, some of which I had not previously visited. A part of my notes were communicated to the Annual Meeting of the Royal Geological Society of Cornwall last November, and with the permission of the Society I propose to reproduce these and additional observations obtained since, with the view more particularly of calling attention to some of the fossils which, though fragmentary, appear to me to yield not unimportant evidence on the stratigraphical horizon of the rocks along certain parts of the coast.

This most remarkable fish, from the Lower Devonian Roofing Slate (Hunsrückschiefer) of Gmünden, in Western Germany, was named, but very imperfectly described, by Schlüter in 1887, as his material was at that time of a very fragmentary nature. He apparently considered the creature to be allied to Cephalaspis. In Dr. Smith Woodward's “Catalogue” (pt. ii, 1891, p. 311) it is only mentioned by name along with a number of other imperfectly known forms (Aspidichthys, Anomalichthys, etc.) which he considered as “perhaps for the most part” referable to the Coccosteidæ.

The existence in Anglesey of a series of dykes later than most of the rocks of the island has long been known. Some of the more conspicuous ones were described by Henslow, many more appear on the map of the Geological Survey, and petrological descriptions were given some years ago (Geol. Mag., 1887–88) by Mr. Harker.

This slight, though not uninteresting, earthquake was of intensity 4, and occurred at about 12.30 p.m. I have 20 records from 19 places, and negative records from 2 places.
