Conjectura agulhasensis ( Thiele, 1925) —new combination

( Figure 9 G–H)

Crossea agulhasensis Thiele, 1925: 66 [100], pl. 8[20], fig. 3. Type loc.: Valdivia St’n 95 (34°51ʹS: 19°37.8ʹE), 7.5 km south of Quoin Point, 80 m; two syntypes in ZMB.

Distribution. Agulhas Bank, from SSE of Knysna to just west of Cape Agulhas 80–110 m (no data for living specimens).

Notes. The type species of Conjectura has been well illustrated by Hickman (2013) and I have no hesitation in referring this South African species to the genus. A second and undescribed species of Conjectura with a higher spire and two prominent peri-umbilical keels has been dredged off the Mgazi River, E. Cape.

# Crosseola Iredale, 1924 . Type species (o.d.): Crossea concinna Angas, 1868 )
