Locus —Shell locality A 444, at sea cliff approximately km. southwest of mouth of Pass Creek, Wide Bay, Alaska Penin- sula. Slmtiiiii iypiciim.—Lower Kialagvik formation, E. howelli zonule at base of E. Iiowelli Zone. Age.—Late Early Bajocian (late Aalenian), E. Itoivelli Zone. Material.—Besides the holotype, a poorly preserved nucleus, compressed except for ultimate 3^4 whorl, from Mesozoic locality F 21 (19755) at Short Creek, Upper E. howelli Zone. Diagnosis.—A cadicone species of Abbasites with greatly de- pressed, evolute whorls. DescriptiotT.—The w4iorl section of the phragmocone is more than twice as broad than high. The sharp lateral edge comprises a right angle and is situated at half whorl height. The broad extern- side is gently and evenly roimded, the inner sides grade into the vertical umbilical wall. The deep timbilicus measures in Avidth more than 40% of the 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 Paleontological Research Institution (Ithaca, N.
