Globigerina (Orbulina) acerosa

Citation: Globigerina (Orbulina) acerosa Owen 1868
Taxonomic rank: species

Current identification/main database link: Orbulina universa d’Orbigny, 1839


Original Description

I propose to make Orbulina a subgenus of Globigerina. The internal chambers are in form remarkably like those of Globigerina, and like them, also, they present themselves with varying surfaces, some free from, while others are covered with, spines. The form without internal chambers has been known under the name of Orbulina universa; I propose now to call it Globigerina (Orbulina) universa. The two forms containing the internal chambers may be regarded as subspecies, and appropriately designated Globigerina (Orbulina) continens, n. sp., and Globigerina (Orbulina) acerosa, n. sp., respectively, the former being without, and the latter having, spines on some of its internal chambers. These spines, as well as those of G. hirsuta, are composed principally of carbonate of lime. I have found that they dissolve in weak acid ; and under Mr. Parker's treatment with boiling potassa they were unaffected, Which proves them to be not siliceous
