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).
Actiniidae with broad pedal disc and rather low body, at least in the contracted state. Column
smooth with 1-5 horizontal rows of vesicles at the margin, these forming weak nematocyst
batteries. Inside the uppermost of them, in the fosse, a circlet of more or less strongly developed
marginal spherules, which are sometimes absent in small individuals. Sphincter diffuse. Tentacles
rather long, they can apparently not be wholly covered by the upper part of the column.
Longitudinal muscles of tentacles ectodermal, radial muscles of oral disc ectodermal or principally
ectodermal. Actinopharynx well developed. Number of siphonoglyphs very variably. Mesenteries
hexamerously or irregularly arranged. Numerous perfect mesenteries. Directives mesenteries
present or absent. Retractors of mesenteries diffuse. Parietobasilar and basilar muscles distinct.
Distribution of the reproductive organs varying, the mesenteries of the first cycle apparently always
sterile. More mesenteries at the limbus than at the margin. Cnidom: spirocysts, atrichs, basitrichs,

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Please note that Carlgren's text contains a number of errors, and much of the information is now out of date.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