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 broad base. Column smooth, variable in thickness, margin tentaculate. Sphincter mesogloeal strong so that
the upper part of the body can cover the tentacles. Tentacles short, conical, fairly numerous without mesogloeal thickenings on
their outer sides, with large microbasic b-mastigophors in their distal parts. Longitudinal muscles of tentacles mesogloeal to
ecto-mesogloeal, radial muscles of oral disc mesogloeal. 2 well developed siphonoglyphs. Tentacles and pairs of mesenteries
frequently arranged 16 (6+10), 16, 32; 16-18 pairs perfect. Perfect mesenteries generally sterile but when the perfect pairs are more
than 16 the exceeding pairs are often fertile, at least the stronger imperfect mesenteries fertile. Considerably more mesenteries at
the base than at the margin. In the youngest cycles the mesenteries of one and the same pair are unequally developed in such a
way that the partner furthest away from the adjacent mesenterial pair of the next oldest cycle is the larger (as in Actinostola).
Retractors diffuse, well developed, parietobasilar and basilar muscles strong. Cnidom: spirocysts, basitrichs, microbasic b- and

About This Page
The information provided on this page is based on Oscar Carlgren's 1949 catalog.

Please note that Carlgren's text contains a number of errors, and much of the information is now out of date.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.
