Description

Description: Shell medium-sized, SL 25-40 mm, fusiform, with up to nine teleoconch whorls bearing prominent shoulder, and with long (around 0.25 of SL), straight siphonal canal. Suture channelled due to elevated subsutural portion of the whorls. Protoconch of .3.5 whorls, upper 1.5 whorls smooth, two last whorls with arcuate axial ribs. Subsutural cord strong, occupying about half width of subsutural ramp, one distinct ridge, sometimes the upper elevated portion of the whorl thickened and looking like an additional ridge. Subsutural ramp concave between subsutural and peripheral cords, with two to three additional smaller cordlets. Peripheral cord as strong as subsutural one, forming shoulder angle, gemmate; gemmae orthocline or weakly prosocline, bifid, 29-40 on last whorl, distinct on entire shell; intervals with two feeble spiral threads. Last whorl with four to five distinct, nearly equally spaced, major cords below peripheral cord, with or without smaller cordlet between major cords. Siphonal canal with more closely spaced, unequal, distinct cords. Aperture (without canal) 0.23-0.25 of SL. Outer lip usually with several distinct lirae, seen only when the shell is rotated counterclockwise, ending about 1 /4 whorl before aper¬ture. Anal sinus on peripheral cord long and narrow. Ground colour palé tan, with slighdy darker subsutural ramp and subsutural cord. Radula comprising 30-60 rows of teeth. Marginal teeth either shoe-shaped or with rather short anterior solid part, constituting 0.25 of total tooth length and major and accessory limbs of similar width (Taylorigemmula barbarae n. sp). Central formation absent, or strongly reduced to indistinct, blunt central cusp.

Etymology: The genus is named after John D. Taylor, eminent British malacologist, for his contributions to the study of molluscs, including Conoidea, and also in reference to the overall similarity of the new genus to the earlier broader concept of Gemmula.
Remarks: The species of Taylorigemmula are remarkably similar in shell outline and sculpture, with slight variation in the number of gemmae on the last whorl and the strength of the subsutural cord.

Distribution: The genus is broadly distributed in the Indo-Pacific from Mozambique and southern Madagascar in the West, through the Philippines and South China Sea to the Solomon Islands, Vanuatu and New Caledonia, at depths of 100 765 m, but mostly shallower than 600 m.
