Metada^ appears to be a vahd genus, distinct from DaiS,no- ceras. Hov^ever, it needs to be emphasized that the sutures of the two type specimens of D. iw))csanum are affected liy grinding and polisliing, and one cannot be sure as to how much these factors have given the suture its apparent simple pattern. None of the specimens of D. nopcsanum in the British Museum (Natural History) show the suture. In addition to Albania, Diiiinoccms is known from a single specimen (D. zap- panense) from the Frohuniiarites faima of Timor. The genus is known also from two species from late Scythian faunas in Kwangsi, C'hina. A fragmentar\' specimen assigned to D. cf. has been recorded from the Narmia Member of the Mianwali Formation in the Surghar Range of West Pakist
