Euphemites yarkangheensis Quo, 1985, p. 464, pl. 163, figs. 9,15.

Description. — Shell thick, elongate-subglobose, whorls slight- ly compressed on the Aanks; dorsum rounded-convex; aperture depressed and reniform, expanded at the sides; umbilicus closed. Surface ornamented by about 22 relatively narrow lirae, con- spicuously grooved carina between two lirae, in addition to a variable number of slender incipient linae at both extremities of the axis. Unornamented area of the dorsum semielliptical in form, the median linae not reaching so far forward as those at the sides. Trace of the selenizone, usually occurring as a shallow V-shaped depression, may be seen clearly on this area. Aperture narrowly reniform, outer lip unknown.

Remarks. — The species Euphemites hindi was first described by Weir (1931, p. 849-850) as a mutation of E. urei (Fleming), Wilson (1967, p. 454) raised it to specific rank. These specimens from Hulustai are similar to those of Scotland in sculpture and in shell shape, diftering is only in their smaller size. This species is also very similar to Fuphemites carbonarius Cox from the late Pennsylvanian (Keechi Creek Shale), but the latter is more globose and has less numerous linae and nodular at the axis. The species resembles Euphemites urei (Fleming), but the for- mer has a larger, more elongate shape and fewer lirae.

Material. — NIGP 22599, 22600.

Occurrence From .— NIGP locality Q2-h-21 from the Upper Member of the Tsingyuan Formation (R2) of Ningxia, China. Wilson reported the species from the limestone coal group (E 1) to the passage group (R2) in Scotland.

Description.— Shell moderate in size, wider than high, tur- biniform, consisting of five whorls. Apex obtuse, apex angle near 90', spire low, body whorl strongly expansive and rounded convex, occupying three — fourths the height of the shell. %horl profile round, suture deeply depresive. Whorls embrace just above upper margin of selenizone, which only can be seen on body whorl surface Selenizone slightly concave, bordered by two spiral cords, lunulate curved lines and fine spiral lines on selenizone. Base rounded convex, anomphalus. Surface orna-
