198 BRITISH FOSSIL CORALS. 
far from the wall. Zadul@ placed at about half a line apart, almost horizontal in the centre, 
but becoming almost erect near the edge. Diameter of the Calices 4 or 5 lines ; diameter 
of the smooth portion of the ¢abu/@ 1 line. 
Found at Rugley, Oswestry, Corwen; according to Prof. Phillips, at Ribblesdale, 
Teesdale, Ashfell, Bristol, and in Northumberland; according to Martin, at Bakewell, 
Winster, and Castleton; and, according to Prof. M‘Coy, in Ireland. It is also met with at 
Viséin Belgium. Specimens are in the collections of the Museum of Practical Geology, of 
Prof. Phillips, Mr. Bowerbank, Mr. Stokes, the Paris Museum, &c. 
L. Martini differs from L. junceum,' L. irregulare, L. antiquum,’ L. harmodites, 
and LZ. Stokesi,’ by the large size of its corallites, and their numerous septa. It is on the 
contrary smaller than Z. afine,® which is multiradiate, and has numerous smal] and 
regular vesicles in the interseptal loculi. Z. Phillipsi’ is the species nearest allied to the 
above-described fossil, but differs from it by the columella bemg less compressed, and by 
the frequent coalescence of the corallites. The other species of this genus, such as 
L. aranea,® L. ensifer,’ L. basaltiforme,” L. Portlocki,” and L. M‘Coyanum,” are easily 
distinguished from Z. Martini by the massive, astreiform structure of their compound

corallum.
