Original Description

Gl. minima, sublaevigata, rotundato-oblonga, subdepressa, in circuito leviter quadrilo­bata, porarum incavationibus latis, polygonalibus in pluribus hexagona quasi reticulata. Spira valde depressa, loculis 8 formata. Loculi parvi, orbiculares, semiglobosi, conferti. Suturae tenerae, latioribus sulcis levibus insectae. Apertura angusta, satis longe fissurata.

Eine sehr merkwurdige kleine Globigerinenform von langlich-vierseitiger niedergedrückter Gestalt, seicht vierlappig mit abgerundeten Ecken im Umriss, nicht ganz glatt von Oberflâche, gleichsam schwach netzartig gezeichnet durch schmale Zwischenleistchen, welche dieseichten, weiteren, polygonalen, meistsogar deutlich sechseckigen Eintiefungen trennen, in der die die Schale durchbohrenden Poren liegen. Die sehr gedrückte niedrige Schale besteht aus acht kleinen randlichen, eng an einandergepresstén, oben und unten sich halbkugelig heraushebenden Kammern. Die schwachen Nathlinien liegen oben und unten in seichten, aber weiteren Nathfurchen, im Umkreis sind sie weit schwacher markirt. Die Mündung ist langlich spaltförmig, schwach sichelförmig gebogen.

A very curious small globigerine form of elongated four-sided depressed shape, shallow four-lobed with rounded corners in outline, not quite smooth from the surface, as it were drawn weakly like a net by narrow intermediate ridges, which separate the slight, further, polygonal, mostly even clearly hexagonal depressions in which the pores that pierce the shell lie. The very flat, low shell consists of eight small chambers that are pressed tightly together and protrude in a hemispherical shape at the top and bottom chambers. The faint suture lines lie above and below in shallow but wider suture furrows; they are far more faintly marked in the periphery. The aperture is elongated slit-shaped, slightly crescent-shaped.
