272 BRITISH FOSSIL CORALS. 
Wenlock limestone: Much Wenlock, Dudley, Aymestry, Benthall Edge. Lincoln Hill, 
Townhope, Little Ridge, Easthope, Malvern (Murchison). 
Middle Ludlow rocks: Aymestry, Tatter Edge near Downton-on-the-Rock Murchison). 
In Ireland, Col. Portlock mentions its existence at Desertcreat, Tyrone, and at Portrane, 
Dublin; and Professor M‘Coy in a great number of localities in the counties of Galway, 
Kildare, Kerry, Mayo, Tyrone, and Dublin. 
This coral is also met with in Bohemia, Sweden, Norway, Russia, and North America. 
Specimens are in the Collections of the Geological Society of London, of the Museum 
of Practical Geology, &c. 
Mr. Hall has separated from this species some specimens, under the name of JZ. 
agglomerata,' confined in the upper part of the Niagara limestone, in Sweden and Ogden, 
Monroe county, and in which the reticulations are proportionally smaller ; but the numerous 
gradations that we observed between these forms, induced us to consider them as being 
only varieties of the same species. We must even add that the distinction between H. 
catenularia and H. escharoides is not as yet clearly established; the principal difference 
between them consisting only in the form of the reticulations, which are much more 
regular and of more equal dimensions in /. escharoides.
