Calliostoma circus Barnard, 1969 View in CoL *

Calliostoma circus Barnard, 1969: 653 View in CoL , fig. 27a. Kensley, 1973: 35, fig. 58. Springsteen, 1981: 4, fig. 6. Type loc.: trawled ‘presumably somewhere off Cape Point’; holotype in SAMC (A30032).

Distribution. Known only from the type material.

Notes. Since no further specimens have been found, it seems probable that the specimen was obtained in deep water, well beyond the continental shelf. The specimen illustrated under this name by Steyn & Lussi (2005: 12, no. 12) has fine intermediary spiral sculpture and appears to be a different species, but its identity is unclear. Ulimately, C. circus may prove to belong to Maurea Oliver, 1926 .
