Entries in the above species list are the original binomina of species according to Carlgren's 1949 catalog. Nomenclatorial inconsistencies need to be resolved in a future revision of this genus (see below).
Actinostolidae with the body, especially in larger individuals, cup-shaped, broad in the upper part, and here more or less
distinctly lobate. Column thick, smooth, or with weaker or stronger flattened tubercles. Margin indistinct. Sphincter mesogloeal,
very weak in comparison with the size of the body, so that the tentacle cannot be wholly covered by the upper part of the body.
Tentacles short, especially the outer ones, hexamerously arranged, in the contracted state irregularly rugose, with or without
thickenings of the mesogloea at the base on the aboral side. Large microbasic b-mastigophors in the distal part of the tentacles.
Longitudinal muscles of tentacles and radial muscles of oral disc mesogloeal. 2 broad siphonoglyphs. Mesenteries at the base
fewer than those at the margin. 2 pairs of directives. The two mesenteries of one and the same pair, in the youngest cycles, are
developed in such a way that the mesentery which has its retractor facing towards the nearest mesenterial pair of the preceding
cycle is larger than its partner. Retractors diffuse, parietobasilar and basilar muscles strong. Mesenteries of the two first cycles
sterile. The fertile mesenteries have filaments. Cnidom: spirocysts, basitrichs, microbasic b- and p-mastigophors.

About This Page
The information provided on this page is based on Oscar Carlgren's 1949 catalog.
Copyright © 1949 Swedish Academy of Sciences.
Please note that Carlgren's text contains a number of errors, and much of the information is now out of date. An update of the catalog is currently under preparation in Daphne Fautin's laboratory, and the results of this work will be incorporated in future versions of this page.
Keyboarding of Carlgren's catalog was done as part of a project to create an electronic database of the sea anemones of the world, funded by NSF Grant DEB9521819, awarded to Daphne G. Fautin. This grant is in the program Partnerships to Enhance Expertise in Taxonomy
(PEET). Susanne Hauswaldt, Katherine Pearson, and April Wakefield-Pagels contributed to the keyboarding effort.
