BLASTOID STUDIES 33 HYPEROBLASTUS GOLDRINGAE (Reimann) Plate 10, figures 1-3, 8; text-fig. 34 Pentremitidea goldringae REIMANN, 1935, p. 26, pl. 2, figs. 1-7. Description.—The figured syntype is 9 mm. long by 6.5 mm. wide, vault 6.5 mm. long, pelvis 2.5 mm. long, and pelvic angle 80 degrees. Hydrospire folds four on each side <strong>of</strong> an ambulacrum. Remarks.—The subspecies H. goldringae juvenis, latus, and obesus are here raised to rank <strong>of</strong> species, taking account <strong>of</strong> radical differences in shape. Occurrence.—Middle Devonian, Pleurodictyum beds, Wanakah Shale <strong>of</strong> Ludlowville Formation, Cazenovia Creek, about 0.12 mile below Transit Road Bridge, on Gehle farm, New York, and old quarry at Bay View, New York. Types.—Syntype, E9,049, one specimen, Reimann collection; plesiotypes, E21,160, five specimens including one thin section, F. W. Wattles collection, from Bay View, Buffalo Society <strong>of</strong> Natural Sciences, Buffalo, New York. The syntype is from Cazenovia Creek.

Description.—Calyx 7.5 mm. long by 4.5 mm. wide, vault 3.5 mm. long, pelvis 4 mm. long, pelvic angle 45 degrees, and five hydrospire folds on each side <strong>of</strong> an ambulacrum. Occurrence.—Middle Devonian, Pleurodictyum beds <strong>of</strong> Wanakah Shale, old quarry at Bay View, New York. Types.—Syntypes, E9,054, E9,054a, two specimens, the former figured, Reimann collection, Buffalo Society <strong>of</strong> Natural Sciences, Buffalo, New York.
