there, it had been denuded and replaced by a more recent bed con- 

 taining Tellina solidula (or BaltMca), which had never yet been found 

 below the Chillesford Clay. They had a most perfect section along 

 the coast. The same beds do not appear in all places, but their 

 order is never inverted. He (Mr. Gunn) concurred with Mr. 

 Harmer that the Chillesford Clay had been very much eroded in 

 places, and much disturbed, particularly at Belaugh. It had been 

 confounded with the banded laminated clay, which was very per- 

 sistent, and formed a good horizon in relation to the Forest Bed and 

 other deposits. The best section was to be seen at Aldeby, where 

 they had, immediately above the Upper Norwich Crag, these banded 

 laminated clays ; then a bed of sand, some few inches thick, support- 

 ing the brown Chillesford Clays. He believed this matter was very 

 important, for in the laminated clays they had occasionally the same 

 shells as in the Upper Norwich Crag ; whereas, in the pure brown 

 Chillesford Clay, none had been found, and only the bones of a whale. 

 This was important as indicating the increasing depth of the waters, 

 and proved the arctic character of the beds. 



Mr. Harmer, in replying, remarked that he had found the presence 

 of mica to be an almost invariable criterion of the Chillesford clay. 



The President then read a brief paper in reference to the state- 

 ment made by sailors, etc., that the ruined church of Shipden was 

 to be seen about half a mile out at sea off Cromer, or its foundations, 

 still standing in situ. The absurdity of the idea does not strike one, 

 unless it is borne in mind that the cliffs rose to a higher eminence 

 than the present (nearly 200 feet), and that, therefore, it is quite im- 

 possible that the foundations of the Church can be standing at four 

 fathoms depth beneath the level of the water. That fragments and 

 large detached masses of walls are to be seen, in clear water, can 

 scarcely be questioned, and Mr. Gunn had frequently seen masses of 

 masonry, at low water, near the Cromer Jetty rolled down from the 

 height at which the buildings stood upon the surface of the land. 

 The President then referred to the Old Cromer Lighthouse, or Beacon, 

 which disappeared in a landslip in 1865. The building was 50 feet 

 in height, and of considerable circumference, but after searching 

 amongst the debris of the landslip, and along the shore, there was not 

 a vestige of it to be seen. It was the opinion of residents on the 

 spot that it fell perpendicularly down, and was engulphed in the slip 

 below. At the present time the debris is nearly washed away to the 

 site of the Beacon, and, consequently, its remains, at least, ought to 

 be detected at the foot of the cliff. The hardness of the beach for- 

 bids the idea that it could have buried itself beneath its level.

 Strophovus medius (pp. 193-6). 

 By the courtesy of Messrs. A. and C. Black, of Edinburgh, we are 

 enabled to add a figure of the lower jaw and teeth of Cestracion 

 Philippi, ' the Port Jackson Shark,' ^ (half natural size) ; the recent 

 type referred to in Prof. Owen's paper as elucidating the characters 

 of the dentition of Stroplwdus.
