Bryozoum consistingof Free or incrustingflat and spreading fronds, or of masses made up of successive layers. The cells are tubular and open by circular or oval apertures, which are furnished with granular or spinulose rims or peristomes, and are irregularly disposed. The space between the cells is eupied below by irregular vesicles and near the top by irregularly superimposed • vesicles, or by mesopores with tabulae. Space between apertures occupied by angular pits, and often, also, by nodes or spines. Base covered by strong epitheca. The genus differs from Fistulipora in its circular cell apertures, 'and in the absence of pseudosepta and ; Dlrich's genus Cyclotrypa, published in Zittel's tology (Eastman's translation), p. 2(59, is a synonym.
