DISTRIBUTION. — The Red Sea and the Indian Ocean, from East Africa to Indonesia, including Eastern Arabia “in corals” (Bosch et al. 1995). Throughout the tropical Pacific Ocean (Cernohorsky 1972), including Hawaii (Kay 1979) and Easter Island (Rehder 1980), extending in the eastern Pacific to the Galapagos Islands (Finet 1994) and the American west coast (Keen 1971). From the New Caledonia area alive in 4-40 m (Oliverio 2008b). Austral Islands, empty shells in 5-500 m, living in 40- 50 m.

REMARKS

This is the type species of the genus Quoyula Iredale, 1912 . It is here conservatively included in Coralliophila . The question of the valid name for this species is dealt with by Oliverio (2008b), who established date and authorship for the binomen Purpura monodonta . Larval shell characters somewhat variable, protoconch of 3.8-4.0 conical whorls, 650-690 µm high and 700-720 µm wide at the base (Oliverio 2008b). It lives on Pocillopora -like corals. Feeding activity was described by Guzmán (1988). Relationships with Purpura porphyroleuca Crosse, 1870 (described from “Polynésie” (Crosse 1870): syntype in MNHN 0946, figured by Kosuge & Suzuki 1985: pl. 41 figs 3, 7) need to be ascertained. However, the present material is more concordant with the type material of Purpura monodonta .
