Material examined. VMNH no. 70638; USNM no. 1283251.

Description. Living colonies brightly pigmented, usually reddish, ranging from light pink to cerise. Colonies encrusting, unilaminar to multilaminar, acicular suboral spines giving prickly texture to colony surface. Frontal shield with weakly granular calcification; a few marginal pores. Growing edge of zooids subrectangular; zooids in frontally budded layers more convex and irregularly polygonal ( Fig. 25 View FIGURE 25 A, B). Zooidal frontal surface rising to peaked suboral umbo; at its base a vertically directed adventitious avicularium with serrated rostrum. Large interzooidal avicularia with lingulate-spatulate mandibles occurring between zooids ( Fig. 25 View FIGURE 25 D).

Orifice subcircular, its proximal margin shallowly curved, with no sinuses or denticles ( Fig. 25 View FIGURE 25 E, F). Ovicells imperforate, globular, cucullate (upper center, Fig. 25 View FIGURE 25 C), their calcification showing suture lines and openings partially blocked by suboral spine and avicularium. Embryos orange red.

Remarks. Colonies from the Oculina samples were all dead when collected, and colony surfaces were broken or partly overgrown by other organisms so that not all characters could be illustrated. However, the large spatulate avicularia and the shape of the orifice are distinctive.

Distribution. Cape Hatteras to Florida, Caribbean, and Gulf of Mexico.
