Editors' Notes
[A new name proposed for Acanthocyrtis Haeckel, 1887a, p.1461, a junior homonym of Acanthocyrtis Haeckel, 1881a.]

[In the original publication (Haeckel, 1881, p.437) Acanthocyrtis was placed adjacent to Eucyrtidium (which genus was marked by an asterisk indicating a new genus!) and stated to be distinguished by ''testa spinosa,'' whereas Eucyrtidium was stated to be characterized by having ""testa laevi."" In 1887 Haeckel (p.1461) used the name Acanthocyrtis first as a subgenus of Cyrtophormis Haeckel 1887 stating, ""shell with numerous (12-20 or more) terminal feet and again later (p.1494) he used it as a subgenus of Eucyrtidium Ehrenberg 1847 where it was differentiated as having "Joints of the shell of very different lengths. Surface spiny. It is apparent that the later description is more nearly in keeping with the original intent of the description of Acanthocyrtis and this name should be retained for a subgenus of Eucyrtidium. For the other group a new name is needed.
The typical subgenus of Cyrtophormis has five to seven terminal feet in contrast with the greater number in this subgenus.]
