" A branching Calamopora : with numerous slender, round or polygonal, transversely- 

 wrinkled tubes, rising perpendicularly in the centre of the branches, and afterwards 

 suddenly curving out to the surface. Interpolated or new tubes numerous, originating on 

 the outside of the old ones. Margin of the apertures with from five to eight spine-like 

 tubercles. 



" It is rather a common Coral, being found at Tunstall Hill, Humbleton Quarry, 

 Dalton-le-Dale, Ryhope-Field House Farm, and Whitley, in the Shelly Limestone. The 

 German localities, according to Schlotheim and Geinitz, are Milbitz and Corbusen, in the 

 Lower Zechstein ; and Gliicksbrunn and Liebenstein, in the Zechstein Dolomite." {King, 

 loc. cit.)

" An incrusting Stenopora. Polypidoms tubular, cylindrical, slightly wrinkled more 

 or less transversely, and in close contact, except towards their orifice, where they are a 

 little reduced in diameter, leaving rather wide interspaces, which are often perforated 

 with interpolated tubes. Apertures circular or slightly polygonal, with a tuberculated 

 margin. 



" It occurs at Humbleton, Tunstall Hill, and Whitley ; but is nowhere a common 

 species. Geinitz's Alveolites producti, which may be the same Coral, is found at 

 Corbusen, in Saxony." {King, op. cit.)

 p. 274, 1851. 



" Tubes or cells adjoining, cylindrical, leaning, concavely arcuate ascendingly, alter- 

 nately overlying each other, and slightly wrinkled more or less transversely. Apertures 

 regularly arranged, circular, occasionally polygonal, margined by a circle of from twelve to 

 fourteen small, closely-packed tubercles, which generally fill up the interspaces. 



" It is a scarce fossil, having only occurred to me once in the Shell Limestone at 

 Humbleton Hill Quarry." {King, op. cit.)
