Lentigo Fetus


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

  • "Shell reaching a height of about 65 mm, rather stout. Protoconch not known. Earliest teleoconch whorls corroded. Number of preserved teleoconch whorls eight. Sculpture of early teleoconch whorls consists of 20 or a little more axial ribs, which are crossed by nine spiral threads. A shoulder situated a little below the middle of the height of the whorl is gradually developed. Simultaneously that part of the axial ribs situated above the developing shoulder gradually disappears. The axial ribs then are transformed into moderately prominent knobs. Profile of whorls above the shoulderstraight on earlier whorls, somewhat concave on later whorls. Number of knobs on late whorls 12 to 13. Dorsal surface of body whorl sculptured by 10 primary spiral ribs below the shoulder and one to two secondary spiral threads on some of thr interspaces. There are two spiral ridges with more prominent knobs below the shoulder. Growth lines near the outer lip prominent. Sculpture on and above the shoulder consists of nine spiral riblets near the outer lip. Aperture long and narrow. Outer lip flaring. Parietal callus smooth except for a few spirally directed wrinkles near the adapical end of the aperture. Inner surface of outer lip smooth with the exception of a few spirally oriented wrinkles near the adapical end of the aperture. Stromboid sinus near the abapical end of the aperture rather shallow. Base of columella bent backward."
