The Costellariidae are one of two molluscan families referred to as Mitre Shells. The Costellariidae are generally characterized by shells with coarse sculpture and strong ribs. The large number of species in this family are mostly small, measuring under 25mm, yet a goodly number grow to over 50mm. The Family is divided into two genera, Costellaria and Vexillum, and Pusia a subgenus of the Vexillum.
Vexillum (Costellaria) roseum (Broderip, 1836) - Mbanika Island, Solomon Islands, 14.7mm - Found in a Bay down the coast from the next large white shell. Ref.: Robin & Martin, 2004, Mitridae Costellariidae, p.24, pl. C-14. Vexillum (Costellaria) roseum (Broderip, 1836) - Mbanika Island, Solomon Islands, 23.4mm - A pure white shell of exceptional size for the species. Found in 30 feet of water on coral. Ref.: Robin & Martin, 2004, Mitridae Costellariidae, p.24, pl. C-14. Vexillum (Costellaria) semifasciatum (Lamarck, 1811) - Guadalcanal, Solomon Islands, 22mm - Found throughout the Indo-Pacific. This shell was collected in ± 4 meters of water buried in sand. Ref.: Robin & Martin, 2004, Mitridae Costellariidae, p.25, pl. C-15; Pechar, Prior, Parkinson, 1980, Mitre shells from the Pacific and Indian Oceans, pl.44, 4 & 6.
Vexillum (Costellaria) takakuwai Cernohorsky & Azuma, 1974 - Philippines, 28mm - uncommonly found in tangle nets set in moderately deep water. Ref.: Robin & Martin, 2004, Mitridae Costellariidae, p.25, pl. C-17. Vexillum (Costellaria) virgo (Linné, 1767) - Solomon Islands, 23.5mm - Dark color form. Found widespread throughout the Indo-Pacific and the Red Sea. Ref.: Robin & Martin, 2004, Mitridae Costellariidae, p.26, pl. C-18; Pechar, Prior, Parkinson, 1980, Mitre shells from the Pacific and Indian Oceans, pl.44, 4 & 6.
