ON SOME PELMATOZOA FROM CHAZY LIMESTONE OF NEW YORK I23 crinidae this ridge usually is continued as an unbroken line along the margins of the radials and brachials up to II Br^, but in this species is broken once or twice on the basal, is lost at the sutures, and appears along the other plates only as a series of rough, elon- gated tubercles; third, the middle portion of the plate shows a few. Fig. s Analysis of Deocrinus asperatiis. The basal and interradial elements are shaded. Between the interradial sutures of the infrabasals the raised casts of the sutures of the proximal stem joint have been faintly indicated. In the lower right-hand corner is an outline of a vertical section through a basal and an infrabasal. The shoulder of the latter which bears the impression of the proximal ring of the stem is shown at C. prominent raised tubercles on either side which indicate ridges which are also represented on the radials by similar tubercles. The radials present about the same area as the basals. The first brachial is smaller and bears also a median row of tubercles. The primaxil is still smaller. The first secundibrachs and the inter- secundibrachs are nearly the size of the primaxil, the arm plates become abruptly smaller at II Bi-g, the first plate of the first pinnules is nearly as large as II Bvr, and is in contact with the three next following Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original New York State Museum; New York State Museum.
