The shell is of medium size, barely pyriform. somewhat
inflated, opaque and glossy. The terminals are elongated and indented. The dorsum is roundly elevated with a hump at the posterior third and with a distinct, somewhat broad and deepened dorsal furrow which narrowing, rarely bisecting the transverse ribbing. The ventrum is flattened with the terminals recurved and with a distinct, somewhat edged, obtuse-angled, mid-ventral keel, which connects the left walls of the anal and siphonal canal. The left side of the mid-portion sloping superficially into the aperture. The aperture is almost straight but curved at its posterior portion. It is narrow but widens somewhat towards the anterior canal. The anal and siphonal canal are indented. The columella is convexly curved without an inner adaxial carina! ridge. The fossula is concave. The fossular edge is excavated and covered by the labrum. The inner edges of the fossula and the columella are separated by an indentation. The labrum is rounded, declive anteriorly, somewhat broad, becoming narrower as it approaches to either end. The posterior part is somewhat excavated. The outer labral margin is curved and rounded. The inner labral edge is barely wavy but posteriorly curved. The dorsal ribbing - 34 on average (varies between 28 and 38)is numerous and close-set. They are continuous from the dorsal elevation becoming more numerous over the side margins, ventrum and labrum. They terminate as sharp, tine teeth on the inner labral edge - 24 on average (varies between 22 and 29). The ribs continue on the columella becoming finer on the columella wall. They - 23 on average (varies between 20 and 26) - are not thickened on the well-developed, edged parietal lip. The parietal lip is curved but somewhat indented at the fossular region. The shell color is white overall.

EXTERNAL MORPHOLOGY
The impression of the animal is in first sight more light in contrast to T. natalensis but the white mantle lobes are also overlaid by dark red-wine or dark brown amorphous patches, blotches and spots. The appearance of the lighter color is strengthened by the large, white, branched papillae with bright white tips. The elongate cylindrical siphon is opaque white or yellowish and overlaid with amorphous pastel orange colored patches of various darkness and similar papillae as seen on the mantle but of smaller size. The slender translucent cephalic tentacles are similarly pigmented as the siphon. The slender foot is also opaque white or yellowish overlaid by amorphous orange to reddish orange patches of various darkness.

RADULA
The radula is of taenioglossate type after the formula 2 -I - I - I - 2. The central tooth is rise up trapezoid with a narrow base. The outline of the outer edge is inversely "U"- shaped. The margin of the outer edge is covered with few weak, irregularly formed, mostly pointed cusps, whereas the central cusp is large, clearly visible flanked by one denticle on each side. The lateral teeth are somewhat wing-shaped - similar like a parallelogram with a prolonged, wavy shaped cusp on the anterior tip as well as two to four minute, irregularly shaped and rounded cusps on its left side and one pointed cusp on the right side. The marginal teeth are very simple, strongly hook shaped and curved with a long, pointed cusp on the anterior tip.
