3. " On tlie discovery of a ' Bone-bed ' in the lowest of the 

 'Lynton Grey Beds,' North Devon." By P. Eoyston Fairbank, 

 M.D. Communicated by Prof. DuncaTi, M.B., F.K.S., Sec. G.S. 



In this paper the author called attention to the occurrence of a 

 thin bed of rock to the west of the harbour of Lynmouth, containing 

 an immense number of fragments of bone, some of them of large 

 size, and associated with massive bodies which he regards as eopro- 

 lites. The author proposed to call this the " Lynton Bone-bed ; " 

 and he thought that its discovery might throw some light on the 

 relative age of the whole series of rocks of North Devon. 



Discussion. — Mr. "Whitaker had examined the beds in company with ]\rr. 

 "Wetherell. He did not agree with the author as to the amount of iron in the beds. 

 The bone-remains appeared to him to be those of Steganoclictyum^ which had already- 

 been found in the lowest of the Devonian beds. He was not prepared ±o accept the 

 nodules described as being undoubtedly coprolites. 



Mr. Valpy stated that there were at least a dozen beds on different horizons of 

 much the same character as that described along the coast of North Devon, an 

 account of which had already been published at Ilfracombe.

Garbo7iiferous Fossils. — Mr. James Thomson, F.G.S., submitted to 

 the Society some remains of fish and molluscan life recently dis- 

 covered in the neighbouring Coal-fields, and which were new at 

 least to the west of Scotland. These were Acanthodes Wardii, from 

 Airdrie ; A tJiyrvs pisiim, from Brockley ; and Anemia corrugata, from 

 Dairy. He pointed out the characteristics of these species, and the 

 relative position of the beds in which their remains occur. 



1. The Acanthodes was a well-preserved specimen, showing the 

 dorsal and anal spines in their natural position. This was of some 

 importance, as these spines had frequently been found singly, and 

 could not be referred to any known genus ; but this discovery 

 enabled palaeontologists to name and classify these ichthyodorulites. 

 Its dimensions are fifteen and a half inches long; dorsal spine, seven 

 and a half inches ; anal spine, fully seven inches ; from the anal to 

 the pectoral spine, six inches. The deepest part of the body is at 

 the pectoral spine, where it measures four and a half inches. The 

 head is wanting. 



2. Athyris. — This little fossil occurs at Brockley, Lesmahagow, 

 and Eoughwood, Ayrshire. From its resemblance to Terebratiila 

 sacculus, it had often been mistaken for that shell. 



3. Anomia corrugata. — This is the first well-authenticated specimen 

 of Anomia that has been recorded from the Scottish Mountain Lime- 

 stone. It is found in a band of shale which underlies the " Linn " 

 Limestone, near Dairy. 



Arctic Shell-bed. — Mr, D. C. Glen, C.E,, gave some notes on the 

 Boulder-clay laid open in the excavation now going on for a new 

 dock at Cartsdyke, near Greenock, and referred to the abundance of 

 Arctic marine shells, and other organisms, found embedded in it. 

 The shell-bed seems to occur in a hollow of the Boulder-clay, which 

 has been exposed to view by a deep cutting running parallel to the
