Type specimens.

Lectotype: ZMB/Moll no. 109267a (Station 95), here designated. Paralectotype A: ZMB/Moll no. 109267b (Station 105); paralectotypes B-D: ZMB/Moll no. 109267c-e (Station 106).

Type locality.

"Station 95 (Cap Agulhas), Station 105 (35°29' südl. Br., 21°2,5' östl. L., 102 m Tiefe) und Station 106 (35°26,8' südl. Br., 20°56,2' östl. L., Agulhasbank)" (South Africa).

Original description.

Station 95 (Cap Agulhas), Station 105 (35°29' südl. Br., 21°2,5' östl. L., 102 m Tiefe) und Station 106 (35°26,8' südl. Br., 20°56,2' östl. L., Agulhasbank), einige, meist junge Schalen haben einige Aehnlichkeit mit der westindischen Triphora triserialis Dall, die aber oben mehr zugespitzt ist. Die weißen Schalen sind sehr schlank mit kaum gewölbten, wenig zunehmenden Windungen, deren erste und zweite kurz abgerundet und mit 2 Reifen besetzt sind, während alle folgenden 3 Spiralreihen von rundlichen Körnchen tragen, an der Naht ist noch ein schmaler glatter Reifen sichtbar. Dieser bildet bei der letzten Windung eine starke Kante und unter ihm ist noch ein Reifen vorhanden. Spindelfortsatz gerade, mäßig lang, Mündung viereckig (bei der abgebildeten Schale beschädigt). Höhe 7 mm, Durchmesser 1,6 mm.

Translation.

Station 95 (Cape Agulhas), station 105 (35°29'S, 21°2.5'E, 102 m depth) and station 106 (35°26.8'S, 20°56.2'E, Agulhas Bank), some of the mostly juvenile shells have some resemblance with the West Indian species Triphora triserialis Dall, which has a more pointed top. The white shells are very slender with slightly rounded whorls which increase little in size; the first and second embryonal whorls are slightly rounded and sculptured with two spiral keels, while all the following whorls show three spiral cords with tubercles; on the suture, another finer smooth cord is visible. The sutural cord forms on the last whorl a strong edge and underneath this edge another spiral cord is visible. The siphonal canal is straight, moderately long and the aperture is sub-quadrangular (the aperture is damaged on the figured shell). Height 7 mm, diameter 1.6 mm.

Diagnosis.

Lectotype height 7.0 mm. Shell very slender, conical, with almost flat whorls. Teleoconch of nine whorls, which have three tubercled spiral cords, well developed since the first teleoconch whorl. A very fine suprasutural smooth cord is also present, but barely visible in most apical whorls. Paucispiral large apex of four whorls; the first whorl bears two strong smooth spiral cords, while the others bear three tubercled cords. Colour white. Base and peristome cannot be properly described on the basis of the studied type material.
