Black lambis - lambis
Two Belgian scientists, whose hobby is conchology, have done some remarkable shell collecting along the Brazilian Coast of
South America. They are Dr. Bernard "Ben" Tursch, 29 years old graduate in bio-chemistry from the "Ecole Polytechnique"
University te'Libre de Bruxelles, and Dr. Jean Pierret, 32 years old and a graduate anthropologist, also from the University
of Bruselles.
Ben Tursch is working for Stanford University of California in Brazil where he is investigating the chemical structure of
some natural products. In his spare time, he collects shells and has over 300 species of Conus alone. Tursch hopes to publish
a catalogue on Brazilian marine shells with the help of local collectors.
The radula: Dr. Schilder (in litt.), did not find any distinct differences between the radula of C . esontropia and C .
cribraria.
Despite the lack of any appreciable differences in the live animal or radula of the two species, the shell possesses
sufficient morphological characteristics to be separated by collectors on sight. The profuse brown spotting of both margins
and thickening of both sides, are a constant feature in all adult shells of C. esontropia. The greater width in proportion to
the shell's length, deltoidal form, and smaller number of labial teeth, are features present in the greater part of shells,
though individuals may vary. C. cribraria lacks the thickening of the columellar margin and deltoidal form. the majority of
shells of any C. cribraria population are unspotted, although rare individuals may bear faint, sparse marginal spots on the
labial or both margins, the columellar spots, however, never extend onto the base. A specimen of C. cribraria from the
Philippine Islands, showed 10 weak, pale brown spots on the labial margin, and 13 on the columellar margin, in form the shell
was elongate-ovate, with the left side rounded, and the columellar teeth extended as strong ridges onto the fossula, thus
separating it from C. esontropia.
