EUNICEA KNIGHTI BAYER, 1961 ( FIG. 8B)

Eunicea knighti Bayer, 1961: 150 (holotype: USNM 50430).

Description: Elastic and slimy colonies up to 0.5 m in height, surface usually smooth without prominent calyxes ( Fig. 8B). Colonies exhibit dichotomous but sparse branching. Branch tips thick and stout. Dry coloration is grey to pale ochre. Sclerites from middle layer ornate and up to 1 mm in length. Anthocodial sclerites include diverse forms and are ornate. Surface layer composed of many torch club sclerites exhibiting congruent rows of ornamentations at the handle.

Diagnostic features: The axial layer presents pale purple sclerites generally short (<0.17 mm) with two or three very notable ornamentations at each side. In its natural environment, this species resembles the slimy forms of Pseudoplexaura spp. but it can be distinguished by noting the black tentacles of the expanded polyp. It is abundant toward deep reef areas (<20 m).

Distribution: Widespread in the Caribbean province.
