CORALS FROM THE MOUNTAIN LIMESTONE. 173 



outer vesicular area (at about the above diameter) one and a half line wide, composed of about 

 four very oblique rows of small rounded cells, extending upwards and outwards, from the 

 broad deflected edges of the diaphragms, which latter are thick, tolerably regular, nearly 

 horizontal in the middle, about three interdiaphragmatal spaces in two lines. 



"Not uncommon in the carboniferous limestone of Kendal." {M'Coy, op. cit.) 

 This Coral appears to be specifically identical with the fossil which the same author had 

 previously found at Kendal, and had referred to Cyathophyllum flexuosum of Goldfuss, 

 under the name of Caninia flexuosa-} for in speaking of C. subihicina he says: "I suspect 

 that this may be the Coral quoted occasionally by authors under the name of the Devonian 

 Cyathophyllum flexuosum." We are also inclined to think that these fossils belong to a 

 species which is found at Tournay, and was described by ourselves under the name of 

 Zaphrentis lortuosa? The description given by Professor M'Coy agrees in most respects 

 with the characteristics of this fossil ; but, as no figure of Z. subihicina has yet been 

 published, and as some of the peculiarities pointed out by that author (the thickness of the 

 septa, and the great size of the fossula, for example,) do not coincide with what we have 

 observed in Z. tortuosa, we have considered it advisable, provisionally at least, to retain 

 here the new specific name given to the British specimens.

No complete specimens of this species have, to our knowledge, been met with ; only 

 fragments, varying in length from 3 lines, to 4 or 5 inches, have been found ; but by their 

 general form it is evident, that this corallum is very long, cylindrical, and irregularly bent; 

 it presents, as usual, some circular accretion swellings ; its epitheca is in many places worn 

 away, so as to leave uncovered the outer edge of the septa, which form equidistant vertical 

 lines. We have seen no specimens in which the calice was preserved. The septa are
