Synopsis
Excerpt from Enumeration of Fossils Collected in the Niagara Limestone at Chicago, Illinois: With Descriptions of Several New Species
Polypary consisting of a mass of crowded cylindrical tubes arranged in ramose and folia ceous forms, both forms being sometimes united in one specimen. The earlier growth, in one Of our specimens, is explanate. The cells are elongated, obliquely horizontal, crowded, overlapping, with their mouths Opening obliquely through the epitheca. The frond devel ops into an irregularly undulate form, sometimes dividing, and some of the lobes bending round laterally, after the manner of one or two turns of an Archimedes. From the border of the frond arise terete, bifurcating branches, with the mouths Opening on all sides. All the cell-mouths are somewhat crescentiform, the outer lip often slightly indented, and some times sufficiently so to give the mouth a triangular outline.
In exfoliated, weathered specimens, the cells are seen to be cylindrical and separately walled, but closely in contact. The width of three of these cells occupies the space of one tenth of an inch; their length is about a third of an inch. No evidences of septa or la mellac can be detected.
