Popis

We have not seen a specimen of this species; the following is translated, without change, from Broderip (1833):
"Shell subovate, white, transversely substriate, the tubes recurved, five-varicate, the varices laminate, sublaciniate with branched fronds. Canal elongate, subrecurved, gracefully curved: length 9/12 [inches, or 18 mm]; width 1/2 [inch, or 12 mm], counted total."
Radwin, G.E. & D'Attilio, A., 1976. Murex Shells of the World. An Illustrated Guide to the Muricidae.
Typhina cleryi: The shell is large for the group (maximum length 24 mm) and broadly fusoid. The spire is high, consisting of one and one-half nuclear whorls and five angulate postnuclear whorls. The suture is weakly impressed, where visible. The body whorl is large and trigonal. The aperture is of moderate size and subcircular to ovate. The peristome is moderately erect, except posteriorly, where it is adherent. Each anal siphonal tube is stout and moderately long; it arises at the shouldermargin, midway between varices, and is bent almost dorsally and somewhat anteriorly at its tip. The siphonal canal is of moderate length, broad proximally, slender, and tubular, bent to the right distally, and completely fused.
The body whorl bears four moderately prominent varices. The most recent varix forms an expanded varical wing, this strongly pointed and hooked posteriorly and dorsally at the shoulder margin; the free edge of the varix is thrown into a series of five additional frill-like, dorsally curved points. The other varices lack most of these details, each consisting primarily of a sharp axial ridge and part of the shoulder margin hook. A moderately thickened axial ridge extends anteriorly from the receding side of the origin of the anal tube and may represent the outer edge of the former peristome. Spiral sculpture consists of a few weak, erratic lines between varices. Shell color is purple to fleshy pink. A series of more or less faint, spiral, red-brown lines encircle the body and are not aligned from one varix to the next. The aperture is white, with a few red-brown spots, these representing the ends of the encircling color lines, at the outer edge of the peristome. The tips of the siphonal canal and anal tubes are stained purple-brown.
