A single shell from Station 244; it shows again brown colour on the upper part of the whorls, on the upper row of tubercles, on the base and on the peristome. The rest is whitish, being in this respect similar to T. angasi, which however is more slender. This species seems not to be described yet. The shell is quite broad and rounded. The first whorl is missing, but the shell is composed by 11 whorls, that are totally covered by three rows of tubercles, which are not too dense. The tubercles are one above the other [probably meaning they are aligned vertically]. The lower whorls are clearly rounded and a deep suture separates them. The periphery at the base is a bit angulated. After the 3 tubercled spiral cords, the base has two rows of tubercles, while a faint lower thread is around the base of the bended columella. The peristome is deformed, externally weakly tubercled. The lower margin of the aperture gets very close to the columella, hence the siphonal canal looks almost closed. Aperture quite small, rounded. Height 7.5 mm, diameter 2.25 mm.

Diagnosis
The holotype is an adult specimen 7.4 mm high. Shell conical with deep sutures. Teleoconch composed by 10 whorls, protoconch missing. Teleoconch sculpture is characterized by three tubercled spiral cords since the very first whorl, the first cord is weaker on the first two-three whorls. A fine suprasutural smooth cord is also visible. The last whorl has a fourth tubercled spiral cord and the base has one more tubercled cord. The peristome has regrown after being broken off, and it is not useful for describing its diagnostic features. Anterior siphonal canal quite long. Colour whitish, with a faint light brown band as background colour of the first cord. Tubercles usually lighter and whiter than the background colour.

Remarks
The apex is missing, but the size of the first teleoconch whorl suggests a multispiral apex.
