Description. —A mid volute form that egresses at um- bilical diameters of 8-10 mm at which point the whorl shape becomes rounded and less depressed. Sutures are unclear but specimen GSC 87800 appears to have an incomplete body chamber approaching one whorl in length. Ribs are simple, densely spaced, and pror- siradiate on the flank. Ribbing becomes less dense or is interrupted by constrictions on the outer whorl. On the inner whorls there are small tubercles at the ventro- lateral shoulder. Type material. —LecXoXype: Hauer, 1861, pi. 1, figs. 16-17 designated by Wiedenmayer (1977, p. 82). Material.—Four specimens preserved in sandstone of the Fannin Formation. Measurements. — See Table 23. Discussion. —This is a microconchiate form that has been paired with the species Aveyroniceras acanthoides (Braga, 1983; Meister, 1989), a species not yet recog- nized in the Queen Charlotte Islands. Occurrence.—Thn is a Tethyan species character- istic of the circum-Mediterranean countries where it is found in the Algovianum Zone of Spain and Mar- garitatus Zone correlatives elsewhere. Localities.-T>1., 106. Age. — KMnae Zone (Late Pliensbachian). whorl section, a combination not normally seen in the more coar
