The largest specimen in the museum is from the Corniferous ; it was about 1 foot long when perfect and ia over 5 inches in diameter at its broadest part. Calamopora basahlm of Goldfuss from the Eifel (pi. XXVI, figs. 4c, 4d, op. cit.) bears a strong resemblance in the size and curve of its corallites and the arrange- ment and size of the pores to F. Hirbinata, Billings. The specimen figured by Goldfuss is a fragment only, so that it is impossible to tell what the shape of the corallum was when entire, although the marked curve of the corallites might suggest a form similar to the typical one of /'. turbin- ata. In the enlarged drawing the pores are in a single row on two sides of the corallites and there is a partly double row on a third side, also in figure 4c the pores are shown in single and double rows. The tabulre are apparently complete. If, at any future time, it is found F. turbinata is the same speci- fically as the coral represented by Goldfuss in these two figures, the name turbinata would still remain in use as the other form of Calamopora basaltica, Goldfuss from Lake Erie (Hg. 4a), which is in the writer's opinion conspecific with F. epidermata, Rominger and was evidently considered the type of the species by its author, as it is mentioned and figured first, should be known as F. bamltica, Goldfuss. It is possible that the Calamopora hemispherica of Troost is conspecific with F. turbinata but the description is so indefinite as to render it a matter of c
