Description

ShEll larGE-sIzEd for GEnus, up To 27.2 MM In hEIGhT; broadlY fusIforM, wITh spIrE abouT 1⅓ TIMEs hEIGhT of apErTurE including siphonal canal; suture deeply indented, siphonal canal constricted, slightly curved to right, terminally truncate, barely indented, rostrum with slight fasciole and false umbilicus; anal sinus deep, U-shaped, at the termination of the second spiral cord; parietal callus-pad well developed; interior of lip with about 6 fine spiral threads; lip preceded by a low, broadly convex varix.

Spire whorls with 3–4 subequal spiral cords (4th cord may be fully visible or barely showing at suture), narrower than their intervals; subsutural cord narrow, smooth, steep-sided, followed by sinus cord with regular, laterally elliptical and low gemmules, 12 to 15 per whorl; third and 4th cords smooth, peripheral, equal in width to subsutural cord; base of last whorl with about 8 main spiral ridges, smooth, widely spaced, those on fasciole close and fine, interstices with a few very thin spiral threads.

Protoconch eroded in all specimens, approximately 3 whorls, the last 1–2 ones with axial riblets.

Background colour cream, with golden brown crests of spirals cords and slightly darker golden-brown maculations in the interspaces of the gemmules of the sinus spiral cord.

Remarks

Turridrupa poppei is similar to Turridrupa magnifica sp. nov. and we refer to the remark section of that species. T. poppei is remotely similar to Turridrupa armillata (Reeve, 1845) but differs in the much larger and broader shell, the less densely-set gemmules, the broader spiral cords, and the completely different colouration.
