Remarks. The illustrated specimen is 21.6 x 15.9 mm in CD, 30.0 mm in height, and 4.1 mm in PD. It has 78 septa arranged in three size classes: 20:20:38. When well preserved, the tissue covering the S1–2 is thick and translucent or light purple. It resembles F. thouarsii , but can be distinguished by its larger pedicel diameter, its widely spaced septa, and its fuller corallum. It is distinguished from F. c u r v a t u m by having a straight and shorter but fatter pedicel (3.5–5.0 mm in diameter), and a circular flat base; a smaller and usually straight corallum (if curved it is curved in the plane of the greater calicular axis). Distribution. Previously known from off Mar del Plata, Tierra del Fuego, and the Falkland Islands at 1647- 2229 m , the records reported here extends geographic distribution from 41.5 to 47.3° S ( Fig. 16 ) and its upper bathymetric range to 749 m , although most records are deeper than 1200 m .
