Introduction
Carlgren's catalog (1949) recognized one genus of Andresiidae, Andresia, containing a single species. Ilyanthus parthenopea is the original binomen of this species. Nomenclatorial inconsistencies need to be resolved in a future revision of this genus (see below).Characteristics

No differentiation of mesenteries into macro-and microcnemes. Retractors diffuse.Andresia: Andresiidae of considerable length with rounded aboral end.

Please note that Carlgren's text contains a number of errors, and much of the information is now out of date.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