Early portion slightly coiled but not completely enrolled, as in Marginulinopsis, later rectilinear, sutures oblique, especially in early portion, aperture of dorsal angle, somewhat produced. [Marginulina glabra D'ORBIGNY, 1826, was cited as type of the genus by CUSHMAN (1913, '*404c, p. 79), despite the fact th~t the type hJ.d previously been fixed by DESHAYES (1830 '*590, p. 416) as Nautilus raplranus LINNE (=Marginulina raphanus D'Orbigny, *590, p.418). The status of the genus as based on the type-species is discussed by Loeblich & Tappan (191, *1179).
