Description
Test large, 1 or 2 mm diam., lenticular, biconvex, trochospiral throughout, chambers numerous, no later acervuline chambers present; sutures radial, depressed, but largely obscured by supplementary lamellar calcite on umbilical side; intraseptal passages present, umbilical cavities interrupted by pillars and radial and lateral canals; wall calcareous, chamber roofs and Roors with 2 layers, thin inner layer and coarsely perforate, thicker outer layer, surface thickly covered with tubercles; 6 to 30 thick, elongate, longitudinally striated, peripheral spines may bifurcate terminally, probably serving for anchorage on reef algae; aperture narrow and strongly indented, interiomarginal, intercameral foramina identical in form. [The type-species, discussed by LOEBLICH & TAPPAN (1962, *1186, p. 33, 34) is Nautilus spengleri GMELIN, by subsequent designation of PARKER & JONES, 1859. The type cannot be Calcarina calcar, either by tautonomy or subsequent designation, as that species was a nomen nlldum in the original publication.]
