Photograph by George Miller
Anthozoa (Dodecacorallia) with flattened, usually adherent aboral end, without basilar muscles. Column smooth without vesicles, verrucae or spherules, sometimes with weak longitudinal muscles. No sphincter or a weak, diffuse one. Tentacles not retractil (sic), simple or branched, the former often with acrospheres at their distal end, usually arranged in radial series, at least in the case of those communicating with the endocoels, rarely arranged only in alternating cycles. Longitudinal muscles of tentacles and radial muscles of oral disc usually weak, ectodermal. Siphonoglyphs very weak or absent. Mesenteries often irregularly arranged. Perfect mesenteries usually numerous, directives present or not. Retractors and parietobasilar muscles weak. Filaments without ciliated tracts. Gonads at the same level as the filaments. Holotrichs numerous, present especially in the endoderm but also in the ectoderm, spirocysts sometimes very rare or absent. Animals solitary or connected by coenenchyme. Cnidom spirocysts, atrichs, holotrichs, micro-basic b- and p-mastigophors.

An inventory of CORALLIMORPHARIA of the world, as of 1949, according to Oscar Carlgren.
Keyboarding of Carlgren's 1949 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). As parts of the database are compiled, they will be made available on the WWW; watch this site for additions! Susanne Hauswaldt, Katherine Pearson, and April Wakefield-Pagels contributed to the keyboarding effort. HTML encoding and formatting were done by Chad Campbell and Adorian Ardelean.
