CORALS FROM THE DEVONIAN FORMATION. 215 



found also at Nehou and Vise, in France ; at Millar, in Spain ; at PafFrath, in the Eifel and 

 in the Hartz Mountains ; in the Oural, in Russia ; in the States of Indiana, Ohio, and 

 Kentucky in America ; and (according to Mr. Lonsdale) at Yass plains, in New South Wales. 

 This fossil was, till of late, confounded with F. gotUandica} to which it bears in fact 

 great resemblance exteriorly ; but it differs from it by the mural pores being more distant 

 from each other, and arranged in two vertical lines on each side of the wall. In F. 

 aheolani and F. asperci" these pores are always situated in the angles formed by 

 the prismatic walls of the corallites, and in F. hasaltica^ and F. polymorphd' they only 

 form a single line, placed in the middle of each side of the wall. In muUipora^ and 

 F. Troosti,^ on the the contrary, there are always three series of pores on each side of the 

 wall. F. parasitica^ and F. Forbesi^ differ from F. Goldfussi by their calices being 

 very unequal in size, and F. Hisingeri may be distinguished from the latter by the 

 great development of the dissepiments. As to the ramose species of Favosites, they are 

 sufficiently distinct from the above-described fossil, in consequence of their form.

Corallum dendroid, composed of thick branches (from half a line to one line in 

 diameter), which intermingle much, and often coalesce. Calices almost equal in size, 

 with thick walls, and having somewhat less than half a line in diameter. 



Found at Torquay in England, at Nehou and Brest in France, Palapaya and Ferrones 

 in Spain, Eifel in Germany, and (according to M. Keyserling) at Uchta in Russia.
