Trophon echinolamellatus: Shell large, fusiform, strongly sculptured with sharply raised spiral cords crossed by closely spaced lamellae produced into hollow recurved spines at the points of intersection. Whorls six including the last whorl of a small protoconch, much eroded in only available material. Spire tall, 0,83 of height of aperture plus canal. Sculptured with fairly prominent flat-topped spiral cords with interspaces mostly of about the same width as the cords. They number four on the first and second post-nuclear whorls, six on the penultimate and twelve on the body-whorl and base, those on the base having somewhat wider interspaces. All the post-nuclear whorls are crossed by numerous thin lamellae which are developed into sharp recurved hollow spines wherever they cross the spiral cords. There are about twenty-two axial lamellae on the penultimate and about twenty on the body-whorl, but they are irregularly disposed. In addition, the surface is scored by weak spiral striations, even on the cords, but not on the actual spines. Aperture ovate, produced below into a short obliquely recurved anterior canal. Fasciole as a high, narrow, spiral ridge imbricated with numerous hollow spines. Outer lip dilated into a polished recurved rim which is crenulated and scalloped along its outer edge by the effect of the surface sculpture. Inner lip, a moderately wide smooth callus with a well-marked, almost free edge. Colour cinnamon-buff to orange-cinnamon with traces of a spirally zoned pattern in slightly darker or more reddish brown; upper zone occupying most of the upper portion of the body-whorl, middle zone much narrower and lowest zone on the fasciole.
Height 63 mm.; diameter 35 mm. (holotype).
Height 64 mm.; diameter 39 mm. (paratype).
TYPE LOCALITY. Off Cape Bowles, Clarence Island

Trophonella echinolamellata is a beautifully ornamented Antarctic trophon endemic to the Southern Ocean, with a range from South Georgia and the South Sandwich Islands to the Antarctic Peninsula although the actual range might be wider. It appears to be extremely rare in the shell market due to its inaccessible habitat and distribution. Originally placed in genus Trophon, it was placed in the newly erected genus Trophonella in 2010 by Harasewych & Pastorino along with four other species due to significant differences from the type species of Trophon, ie. Trophon geversianus (Pallas, 1769). It is a carnivorous gastropod with a bathymetric range of around -50~500m, but live specimens are usually found between -100~200m deep. Typical shell length approximately 50mm., very large specimens are known to attain nearly 70mm.
