Pseudotextularia elegans

Taxonomy

Original description: Die Textularideen sind, was Individuenanzahl anbelangt, recht gut vertreten; die merkwürdigste Form ist Cuneolina elegans m., über welche ich bereits einmal (Verhandl. des naturf. Ver. in Brunn, Bd. XXIV, Sitzungsber., pag. 8; Verhandl. der k. k. geol. R.-A., 1888, Nr. 9, pag. 191) Mittheilungen gemacht habe. Ich bezeichne mit diesem Namen eine kleine Textularidee, die sich von den gewöhnlichen Textularien dadurch unterscheidet, dass sie in entgegengesetzter Richtung zusammengedrückt ist, eine grosse, bogenförmige Mündung besitzt, mit zarten Streifen verziert ist und derart zur unregelmässigen Vermehrung der jüngeren Kammern hinneigt, dass der obere Theil mancher Individuen ganz traubenähnlich gestaltet ist. Es wird wahrscheinlich zweckmässiger sein, diese merkwürdigen Formen, die ich auch aus dem mährischen Alttertiär kenne, zu einem selbstständigen Genus zu erheben, wofür ich schon früher einmal (I.e.) den Namen Pseudotextularia vorgeschlagen habe. Es ist nicht unmöglich, dass die mehrzeiligen Textularien, die Ter que m aus dem Pariser Eocän — leider sehr unvollkommen — beschreibt, hieher gehören.
