Persististrombus Insulanus

Stromboidea


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

  • "Shell reaching a height of about 55 mm, slender. Protoconch and earliest teleoconch whorls not known. Number of preserved teleoconch whorls eight. Sculpture of early teleoconch whorls consists of three varix like axial ribs and two smaller axial ribs in each interspace. These are crossed by six to eight spiral threads. On successive whorls secondary spiral threads appear. On later whorls the spiral threads become subequal in strength, and, at the same time, the axial ribs change their shape into subequal knobs situated on a gradually developing shoulder. There are nine moderately pointed knobs on the last whorl. Dorsal surface of body whorl not preserved, but left side of body whorl clearly shows three spiral rows of small knobs, which - as well as their interspaces - are sculptured by spiral threads. Outer lip not preserved with the exception of its adapical part. Parietal callus smooth. Inner surface of preserved part of outer lip smooth. Base of columella bent backward."
