Page 46 - Zoarium consisting of bilaminar fronds, from 2 to 6 mm. thick and 10 or more cm. in height. Fronds usually somewhat undulating and occasionally producing fronds at right, angles. Some specimens branch rather frequently, others rarely. Surface smooth, except for clusters of larger cells which sometimes rise a little above the general level. Apertures circular, 7 or 8 of the ordinary size in 2 mm.
Page 46 - Often the center of a cluster is occupied with a large number of mesopores. In some specimens few mesopores are present. Occasionally a specimen shows a large number of small acanthopores at the surface, and these may also be seen in some sections. Zooecia have a very short immature region; in the mature region they have a linear series of overlapping cystiphragms and a few diaphragms.

Ulrich and Bassler, Smithsonian Miscellaneous Collections, vol. 34, 1904, p. 37. Zoarium consisting of small fronds, or of rounded or compressed branches, about 3 mm. in thickness and from 4 to 7 mm. in breadth, and from 15 to 30 mm. in height. Division occurred at short, irregular intervals, and an entire zoarium consisted of a small clump of closely interwoven narrow branches....

However, as the sediments were deposited in different basins and under very different conditions, and as the faunas have scarcely anything in common, it seems better that they should 5>ear different names; hence Orton's name Eden is revived for the formation developed in the Ohio Valley.
Page 46 - ... Collections, vol. 47, p. 26, pl. xi, 4-6, 1904. Zoarium forming large, flabellate expansions from 10 to 15 mm. in thickness. Surface smooth ; maculae not a prominent feature, often scarcely distinguishable. Apertures small, angular, thin-walled, about 10 in 2 mm. In the immature region the...
Page 56 - Hist., vol. 5, p. 254, pl. xi, 5-5c, 1882. Zoarium ramose, consisting of cylindrical or subcylindrical branches, which divide dichotomously at irregular intervals, and vary in diameter from 7 to 20 mm. Surface smooth or almost so, with clusters of 7 to 15 larger apertures, which are sometimes a very little elevated above the general level. Apertures polygonal, often somewhat rounded from the thickening of the walls, those in the clusters from 0.4 to 0.5 mm. in diameter, while the others are a little...
Page 20 - ... without a magnifying glass, and require rather careful discrimination. They look much alike at first glance. For careful work microscopic sections are necessary. The bryozoa seem to have been a rather sensitive type of life, changing readily with changing conditions, yet possessed of great race vitality, for they are abundant even to-day, while the brachiopoda have but few living representatives. However, the suborder of bryozoa most abundant in the Ordovician, the Trepostomata, diminishes greatly...
Page 51 - Zocecia are somewhat irregular in their course, thin walled and without diaphragms in the axial region; in the mature region they have well-developed, ring-like, walls, and diaphragms varying from 2 to 3 or 4 in the space of two tube diameters.
Page 9 - Kentucky to determine for geologic mapping purposes the boundaries between formations in certain doubtful cases, and to ascertain to what extent the subdivisions of the Cincinnatian series made in Ohio and Indiana can be recognized in Kentucky. This examination forms the basis of this report. For lack of time a considerable part of the collections of fossils made could not be examined, hence the report lacks the fullness and completeness whiich the subject deserves.
