Material.—Two dorsal internal moulds.
Discussion.—The minute, slightly transverse shells of Nothorthis perplexa are rare but well preserved together with the large shells of Martellia and Leptellina . The brachiophores are rod−like with widely divergent brachiophore bases ( Fig. 8L 1 View Fig , L 2 View Fig ). The cardinal process is small, ridge− or knob−like. The multicostellae are somewhat less numerous than in other species of Nothorthis . These characters are essentially identical to those of the same species from the Dashaba Formation (see Zhan and Jin in press).
