Original Description of Strombus (Lentigo) toroensis by Jung & Heitz, 2001:

  • "Shell reaching a height of about 70 mm, moderately slender. Protoconch and earliest teleoconch whorls not known. Earliest preserved teleoconch whorls sculptured by three primary axial ribs per whorl with first five, then four, and later three and two secondary axial riblets in their interspaces. Primary and secondary axial ribs are all over-ridden by 10 spiral riblets. Secondary spiral riblets are introduced at an early stage. On later teleoconch whorls there are 10 subequal knobs per whorl, which become somewhat pointed on the body whorl. Number of knobs on body whorl nine. Dorsal surface of body whorl with three spiral rows of knobs. The most adapically situated row not prominent, the central row prominent, and the third, most abapically situated row less prominent than the central row. Remainder of dorsal surface of body whorl sculptured by numerous faint axial and spiral threads. Aperture long and narrow. Parietal callus smooth. Outer lip a little flaring, its inner surface smooth except for a few spirally enlongated denticles near the shallow sinus. Base of columella bent backward."
