Nidalia occidentalis Gray 1835:60   .— Deichmann 1936: 56; Plate 1 fig. 3[sic. 5]; Plate 4 figs. 1–3.— Utinomi 1958:102; Figs. 1–3.— Bayer 1961:53; Figs. 9h, 10a–c.— Verseveldt 1978:45.— Verseveldt and Bayer 1988:59; Figs. 42e–g, 45, 47b, 52, 53. — Cairns et al. 2002:33.

Material examined. SERTC S 1384, 63 m, off Anastasia Island , FL, August 30, 2004   . S 2325, 92 m, off Charleston , South Carolina, April 12, 1974   . S 2788, 60 m, off Anastasia Island , Florida, August 31, 2004   .

Remarks. Nidalia occidentalis   is easily distinguishable from other octocorals in the SAB by its stiff, barren stalk and capitate head bearing the monomorphic polyps and conical calyces. The stalk bears large (up to 1 mm), slightly curved, tuberculated spindles while the anthocodiae contain smaller needle-like rods in a collaret and points arrangement, and small flat platelets. The large spindles are six times longer than wide, a feature that distinguishes N. occidentalis   from N. rigida   , which bears thicker spindles. In life, one SERTC Nidalia occidentalis   specimen had an orange stalk and red terminus bearing white polyps. In the preserved state the colors are slightly duller. The examined specimens reach 20 mm in length.

Atlantic distribution: North Carolina to French Guiana, Gulf of Mexico, Caribbean, 37–440 m (one record off Venezuela indicates collection from 914 m) ( Deichmann, 1936; Bayer 1961; Verseveldt 1978; NMNH collections; SERTC collection).
