Striatobalanus amarylli s ( Darwin, 1854)

( Figs 6 a–g)

Material examined. ZUTC-cirri 1174, 1175, 1176, 1177, 1178.

Persian Gulf. Stubbings (1961) as Chirona amaryllis from Kuwait; Utinomi (1969) as Chirona amaryllis from Khark Island, Bushehr, and Bahrain ( Fig. 1 ); present study.

Gulf of Oman. Utinomi (1969) as Chirona amaryllis from an unknown locality; present study.

General distribution and habitat. Indo-West Pacific; fouling various substrata; intertidal to 500 m depth ( Jones et al. 2000; present study).

Descriptive features and remarks. Shell white or white with purple area or purple stripes, or purple with red stripes. Orifice mostly rhomboid, diameter half of diameter of basis in conic specimens to equal to basis diameter in cylindrical shells ( Figs 6 f, g). External surface of scutum and tergum striated strongly or weakly ( Figs 6 a-e). Largest specimen (ZUTC-cirri 1176) with basal diameter 49.86 mm, height 41.9 mm.

Specimens were collected from various substrata such as rock, horny coral, mollusc shells, ships and floating objects at Dayyer (27° 49'N, 51° 55'E), Bandar-Lengeh (26° 30'N, 54° 39'E), Bandar-Abbas (27° 04'N, 56° 16'E), Djod (25° 27'N, 59° 30'E), Chabahar (25° 19'N, 60° 37'E), and Gwatr (25° 08'N, 61° 27'E) ( Fig. 1 ).
