Illustration available in Hinds (1844) : 28, pl. 8, fig. 3. Type locality. Straits of Malacca. Type material. Syntypes : NHMUK 1844.6.7.17- 19, 3 specimens , Straits of Malacca (coll. E. Belcher) ; NHMUK 1855.11.15.20, 1 specimen , no locality (coll. E. Belcher) ; NHMUK 1879.2.26.201, 1 specimen , Straits of Malacca (J. Lombe-Taylor coll.) . Original description. Testa pallide rufente; anfractibus 15-18 biseriatim granoso-carinatis, medio laevigatis carina secundaria; prope suturam carinula monilifera; sinu laterali patulo. Axis 41/2 lin . Geog . Straits of Malacca; in 3 fathoms. Translation of the Latin text. Shell pale reddish; 15-18 whorls with two granulated-keeled cords, with a smooth interspace with a secondary keel; a thin granulated keel near the suture; open posterior sinus. Height 41/2 lines. Diagnosis. Subadult syntypes ca 9 mm high. Shell conical, with flat whorls bearing two quite thin main spiral cords with large oblong tubercles at the intersection with broad axial ribs. A third very fine spiral cord develops early in the teleoconch but never attains the strength of the other two whereas a fourth smooth cord is visible above the suture. A microsculpture of very fine threads is visible between the main cords. The apex is incomplete, but clearly bears a brown multispiral protoconch whose last two whorls have two strong spiral keels and axial riblets. The teleoconch has a whitish background with orange to brown flammulae. Remarks. All available syntypes are subadults without a fully developed last whorl and peristome. Specimens NHMUK 1844.6.7.17 (Fig. 37A, B ) and NHMUK 1844.6.7.19 (Fig. 37H ) are probably those that best fit the figure by Hinds (1844) in terms of sculpture, colour pattern and shell profile. In contrast, NHMUK 1844.6.7.18 (Fig. 37G ) has a much more slender profile and resembles Triphoris bilix Hinds, 1844 (p. 185), NHMUK 1879.2.26.201 (Fig. 37J ) is again more slender and has more numerous tubercles on the third spiral cord, superficially resembling T. concors Hinds, 1844 (p. 193), and NHMUK 1855.11.15.20 might be a Triphoris sculptus , but it is too ruined for proper identification.
