Measurements
ZL, 0.75–0.99 (0.846¡0.064). ZW, 0.43–0.65 (0.533¡0.075). OrL, 0.18–0.23 (0.197¡0.016). OrW, 0.21–0.25 (0.230¡0.012). OvL, 0.325. OvW, 0.475 (ovicell n 51).
Description
Colony unilaminar, encrusting, sheet-like; tan in colour; ectocyst and operculum light yellow. Zooids hexagonal to barrel-shaped, longer than broad. Frontal wall slightly convex, granulated, covered with tiny pores uniformly distributed over entire surface, often with larger areolar openings at proximolateral corners of zooid and lateral to orifice. Orifice raised on imperforate, granulated peristome; with strong condyles; poster slightly broader than anter; proximal orificial margin convex, flattened on top in zooids with an ovicell. Orifice dimorphic, much broader proximolaterally in zooids with an ovicell than in those without. Some zooids have an avicularium on one side of orifice, the rostrum long-triangular, acute, curved laterally. Ovicell comprises a flattened, sac-like enlargement of distal end of zooid, the surface granulated. Spines lacking.
Remarks
Our material is similar to Harmer’s (1902) original description in overall zooidal measurements, in having the orifice dimorphic between zooids with and without an ovicell, and in having a long-triangular avicularium on one side of the orifice in some zooids. Our specimens differ in having the orifice broader than long in zooids not bearing an ovicell; in having smaller, more numerous pores, and in having the avicularian rostrum typically curved laterally, rather than straight.
Distribution
Previously known from Torres Straits ( Harmer 1902); the Straits of Korea ( Okada 1923); Aru I., Indonesia ( Harmer 1957); and the Hawaiian Islands, locality unspecified ( Soule et al. 1988).
