“…The present specimen conforms well to the original description of Polyclinum saturnium given by Savigny (1816) and its subsequent one by Tokioka (1962b), especially in the colony shape, thoracic musculature and the number of stigmata! rows.…”

“…Osaka Bay (Tokioka, 1962b), west coast of Kii Pen., 3.5 m deep (Nishikawa, 1980b) and Sagami Bay, 80 m deep (Tokioka, 1962b), Japan; Gulf of Suez (Savigny, 1816;Hartmeyer, 1915b;Michaelsen, 1920); Gulf of Aquaba (Van Name, 1952); Red Sea (Michaelsen, 1920).…”

“…6, and this revealed that the spicules were, if present, found most frequently in the heart wall and the dorsal tubercle. The horn-shaped spicules are transparent, colorless, and cannot be dissolved in a solution of hydrochloric acid in contrast with the spicules of Herdmania momus (Savigny), that are mineralized with vaterite (CaCOa) (Lowenstam and Abbott, 1975) and Test consistency and colouration: In smaller specimens, the test is thin, soft, leathery and somewhat translucent, and milky white usually with a pinkish tint in the dorsal region, while in larger ones, it is hard, cartilaginous and generally thick, up to more than I 0 mm in thickness (though very thin, in some cases, on the attachment side), and purplish pink or, in lesser cases, pale brownish, as already noted by Tokioka (1954) …”
