106 CARBONIFEROUS CORALS AND BRACHIOPODS 
upon thousa.nd specimens to be observed, sectioned and 
weathered out, in the rocks themselves. The results of 
such observations I hope to set out at no very distant date. 
Lithostrotion Martini, Ed. and H. { — L. fasciculatum, 
Auct. [non Lam.]). 
Here we may place a weathered specimen showing deep 
calices, about 8 mm. in diameter, and a polished slab 
which shows a large number of disconnected, but fairly 
adjacent, cross sections, averaging 5 mm. in diameter. 
None of the specimens are located. 
Lithostrotion irregular e, Phill. 
A weathered specimen, composed of very many narrow, 
cylindrical corallites, closely packed together, parallel and 
flexuous, was derived from the upper beds of the section. 
Numerous disconnected corallites which exhibit a 
characteristic forking were obtained from the very top 
beds of the series. 
Lithostrotion junceum, Fleming. 
A single typical specimen is unlocated. 
Section B. Nematophyllum, McCoy, comprising the 
astrieiforin Lithostrotions. 
Of this section there are a great number of specimens, 
the majority polished sections, which represent fully and 
excellently all the species belonging to this section which 
are found in the Carboniferous Limestone series of the 
Bristol area. 
Lithostrotion basalti forme, var. hristoliense (commonly 
known as Lithostrotion aranea, probably = Nemato- 
phyllum arachnoideum, McCoy). 
Corallum much expanded, the calicinal surface only 
slightly convex.
