Corallum forming small globular masses, and usually adhering to the stem of an 
Encrinite. Walls very thin. Calices unequal in size ; some very small ones near the 
angles of the larger ones ; the latter 1 or 1} line in diameter. 
Fossil from the Carboniferous Limestone at Bolland, in Yorkshire; and according to 
Professor M‘Coy, in Ireland. 
The fossil designated by Colonel Portlock’ and by Professor M‘Coy,” under the name 
of Favosites Gothlandica, appears to belong to this species. The specimens mentioned by 
the first of these geologists were found in ‘Tyrone and Derryloran ; those described by the 
latter were met with in the Isle of Man, and in Derbyshire. A collector of the Museum 
of Paris, M. Marcou, found at Button Mould Knobs, near Louisville, in North America, a 
Coral, which we equally refer to the above-described species, although its calices are 
somewhat smaller. 
The genus Favosites, which is so abundant m the fauna of the Silurian and 
Devonian Periods, appears to be represented only by the F. parasitica in the Carboni- 
ferous Formation; and the other fossils that various authors have described under this 
generic name, or as Calamopora, ave now referred to different genera. We must, however, 
not omit mentioning here two Corals that are not sufficiently well known to be classed 
zoologically, although they probably are not true Favosites. 
One of these fossils is the Calamopora incrustans of Professor Phillips.’ It was found 
in the Carboniferous Limestone at Bolland, and is known to us only by a very rough 
figure, given by that distinguished geologist. 
The other is the Calamopora dentifera of the same author ;* it was met with at 
Bolland, but in the present state of Paleontological science cannot be characterised.
