Triphora insularum Biggs ms [unavailable]

Triphora sp. Biggs, 1973: 362–363, pl. 4, fig. 4, 5.

Type locality. United Arab Emirates, N.E. of Abu Dhabi.

Type material. NHMUK 1968760–198763, specimens meant to become holotypes and paratypes .

Distribution. United Arab Emirates (Biggs 1973; Albano et al. 2019).

Remarks. Biggs (1973) described this species but did not introduce a name because the specimens he had available lacked the protoconch, a fundamental character for species identification in Triphoridae . Specimens with this name were found in the NHMUK but the name is unavailable as never formally introduced. Albano et al. (2019) figured the specimens.
