Corallites averaging about one line in diameter, straight or slightly fk-xuu-. distant 

 from one another their own diameter or a little more, connecting tubes horizontal or slightly 

 oblique, varying in their distance apart, bat usually from two to four lines distant ou the 

 same side of any given corallite ; surface obscurely or deeply annotated. 



This species is very closely allied to > v pora reticulata (GukH'uss), from the Carbo- 



niferous rocks of Europe, differing perhaps in nothing except that the connecting p 

 are not quite so closely set. It is also nearly related in many respects to ,\ Ma Hil- 



lings), it being very difficult to decide with regard to certain specimens to which of the two 

 form.- they should be rightly r ferred.

and very abundant at Lot 6", Con. 1, Wainflect ; also in the Corniferous Lirne-t< -ne of Wood-

 and often twof three, or four lines apart. In large colonies which have gn-wn luxuriantly 



without the interference of disturbing causes, the corallites are more regular than in the 

 smaller or stunted groups, in which the corallites are much bent and confused. The
