Habitat and distribution.

Recorded from the eastern Atlantic Ocean from the Porcupine Abyssal Plain (southwest of Ireland), south to equatorial latitudes, 4510-5300 m in depth. ( López-González and Williams 2011: 314) (Fig. 6A View Figure 6 ).

Description.

The six whole colonies from the Porcupine Abyssal Plain that were examined for this study range in length from 29-41 mm (Figs 4 View Figure 4 , 5 View Figure 5 ). The colonies are slightly crescent-shaped to more-or-less straight. The polyp-bearing portion of the upper stalk is somewhat widened, forming a keel, where the relatively large lateral polyps are arranged (Fig. 4 View Figure 4 ). The axis is present throughout the length of the colonies, and is discernably wider in the rachis and is very close to the surface, which provides more rigidity to the polyp-bearing portion of the rachis. The total number of autozooids in any given colony is generally five - one terminal polyp and four lateral polyps. The siphonozooids are not particularly numerous and are presented as low rounded mounds on the surface of the rachis between the lateral and terminal autozoods and just proximal to the lateral autozooids. The distal portion of the stalk that contain the polyps is narrowly spearhead-shaped, and ends with a pointed tip or beak (Figs 4 View Figure 4 , 5A, B View Figure 5 ). A single terminal polyp emanates from the base of the distal terminus. Two pairs of lateral polyps are oppositely disposed on the spearhead-shaped upper portion of the stalk. (Fig. 5 View Figure 5 ). The proximal end of the short peduncle is somewhat [slightly] swollen and forms a relatively narrow, elongated bulb (Figs 4 View Figure 4 , 5A, F View Figure 5 ). Conspicuous sclerites are absent in all parts of the colony, with the exception of extremely small ovals in peduncle interior. The color of wet-preserved colonies is uniformly white throughout (Fig. 5 View Figure 5 ).

Remarks.

At least twenty-five collected colonies are known, thirteen of which are deposited at the Muséum national d’Histoire Naturelle ( MNHN), six at the Biodiversidad y Ecología de Invertebrados Marinos of the University of Seville (BEIM), and six at the California Academy of Sciences ( CAS).
