Strobeus ? sp. 2

(Fig. 22 D–E)

Material. Two specimens: ESKU-19- LP 217, 220.

Dimensions (mm): ESKU-19- LP 217: height = 1.4; width = 1.0; apical angle = 76 º. ESKU-19- LP 220: height = 1.3; width = 1.0; apical angle = 78 º.

Description. Shell fusiform, distinctly higher than wide with about three whorls (apex missing); periphery evenly rounded, convex; whorls embracing at or slightly above periphery; spire whorls slightly convex; whorls smooth; body-whorl inflated; suture shallow; base rounded, convex; anomphalous; aperture unknown.

Remarks. The two specimens resemble Strobeus dongluoensis (Pan & Yu, 1993) from the Upper Permian Changxing Formation, China (see also Pan & Erwin 2002; Nützel & Nakazawa 2012). The identification of the present specimens remains doubtful due to insufficient preservation.
