Description

The shell is moderately large (maximum length 90 mm) and fusiform. The spire is high, consisting of nine weakly subangulate postnuclear whorls and a protoconch of undetermined nature. The suture is impressed. The body whorl is of moderate size and fusoid. The aperture is of moderate size and ovate, with a narrow, moderately deep anal sulcus. The outer apertural lip is barely erect and crenulate, strongly lirate on its inner surface. The columellar lip is arched, adherent above, detached and erect below, and heavily callused. The siphonal canal is of moderate length, curved, and barely open.
The body whorl bears three briefly foliose varices. Intervarical axial sculpture consists of two costae of unequal prominence, the larger one always situated nearer the growing edge. Spiral sculpture consists of six primary cords, four on the body and two on the canal, and one or two intercalary cords between consecutive primary cords. Fine threads are apparent over the entire shell surface but are more densely distributed in three transverse bands, one above and on the shoulder margin, one medial, and one at the base of the body. The primary and secondary cords end at the varical margin in weakly foliated spines of different lengths, the longest, at the shoulder margin, open ventrally and bent back, as are all the primary spines, the other spines bent ventrally. The two anteriormost spines are joined by a webbing.
Shell color is white, with diffuse brown coloration in some areas. The crests of the spiral threads are dark chestnut-brown, imparting to the three areas of greatest thread density the appearance of transverse brown bands.

Distribution

If we have correctly associated Lobbecke's name with the D'Attilio specimens, the species is indigenous to the Red Sea area (the specimens are from the Gulf of Aqaba).
