Triphoris suturalis Adams and Reeve 1850: 45, pl. 11, fig. 29a, b.

Type locality.

"China Sea".

Type material.

Not found, see remarks.

Original description.

Triph. testâ turritâ, anfractibus duodecim ad tredecim, eximiè triseriatim granuloso-carinulatis, suturis concavo-impressis, laevigatis; pellucido-albâ.

Hab. China Sea.

The aperture of this delicately grain-keeled species, which is characterized by its hollow sutures, is incomplete.

Translation of the Latin text.

Turreted triphorid with twelve to thirteen triseriated whorls well developed with carinated granules, and concave-impressed smooth sutures; clear-white.

Hab. China Sea

Remarks.

The specimen preserved in the type collection of NHMUK (196513) has 10 whorls instead of the 12 to 13 stated in the original description. Adams and Reeve also highlighted that the studied specimen had an incomplete aperture and particularly hollow sutures. The specimen in NHMUK has an incomplete peristome and impressed sutures, although not unusually hollow for many triphorids. We refrain from considering these specimens as syntypes until further evidence is available. At present, T. suturalis should be considered a nomen dubium.
