Adult shell large, 69-94 mm. (23/4-33/4 inches) in height, fusiform with turretted spire and moderately long anterior canal. Height of spire about equal to height of aperture plus canal. Whorls eleven plus a small bluntly rounded protoconch of 1,5 smooth whorls followed by a half whorl of closely spaced brephic axials. Spire-whorls with a broad steeply descending concave shoulder area which extends from the unmargined suture to a somewhat rounded but distinct angulation at a little above middle-whorl height. From the angulation to the lower suture there are strong slightly protractively oblique axial folds, about twelve per whorl. These fade out on the upper base at a little below the level of the top of the aperture. The whole surface is densely spirally lirate. Sinus sigmoid, deep but rather narrowly rounded at its apex which is towards the lower extremity of the shoulder area, then produced forwards in the great arcuate sweep of the outer lip, which is thin edged. Colour buff to light-brown, zoned with reddish-brown; one zone occupies the shoulder area, another the upper base and a third covers the anterior fasciole. Variations include one in which neither the shoulder area nor the anterior fasciole is zoned but the shell is two banded, one coinciding with the axials and the other situated on the lower base. Deep-water examples are usually devoid of colour pattern. Operculum leaf-shaped with a terminal nucleus . Height: 69,5 – 94 mm.; Width 21,0 – 31,5 mm.

The « Kaderly's Turrid » is a large and beautifully striped 'turrid' with a distribution from Sagami Bay, Japan to Philippines. A carnivorous gastropod inhabiting fine sandy bottoms, it is usually found in moderately deep water ranging between -150~450m but records exist from as deep as -1600m. It is best known from southern half of Honshu, Japan; and although a locally common species live-taken specimens are somewhat uncommon. A rather invariable species, knobs are prominent in the earlier whorls but weakens towards the final whorl. Very fresh specimens often carry a lovely purple hue which generally fades quickly. Typical shell length around 75mm., very large specimens may exceed 100mm.

This is a well-known member of the Japanese shelf-fauna characterized by its large size, fusiform shape, strong fold like axials and buff to light-brown ground colour, faintly banded in darker brown. The Baracay Island specimen shows faintly the characteristic colour zoning but those from the Japanese station 3698 as well as those from the Philippine stations 5494 and 5429 are entirely lacking in colour pattern. Also, there is a slight tendency towards more oblique ribbing and a wider sinus in all the deep-water Philippine ma¬terial, with the exception of the Panay specimen, station 5429, which is inseparable from Japanese examples. There is insufficient material to determine it a bathymétrie subspecies is represented or if the slight variations mentioned above are admissable within the normal range of the species.
