In 1781, Lorentz Spengler, curator of the Royal Collection of Art, Crafts and Rarities of Nature, Den­mark (1771-1807), described several foraminifera from sand obtained from the interior of large gas­tropods. On sectioning these minute foraminiferal tests he observed that they had no siphuncle (thus predating d'Orbigny's well-known observation of 1826) and that the septa curved in the opposite direc- tion to those of Nautilus "and the Ammon's Hom". One of Spengler's species was named Calcarina stellata by de Ferussac in 1827. This is a valid senior subjetive synonym of Pararotalia ea/car (d'Orbigny, 1839), and an application has therefore been made to the International Commission on Zoological Nomanclature for its suppression. The type species of the genus Calcarina was described and illustrated by Spengler (1781) and named Nautilus spengleri by Gmelin (1791). The type was described from sand contained in an east Indian gastropod. The gastropod has been located in the Zoological Museum, Copenhagen. It still contained some sediment, from which a neotype has been selected.
