The species in R. Sturany: “Zoologische Ergebnisse VII. Mollusken I gesammelt von S.M. Schiff ‘Pola’ 1890-1894”, Denkschriften der Kaiserlichen Akademie der Wissenschaften vol. 63, Wien 1896, plate I – this is in the Berichte der Commission für Tiefsee-Forschungen XVIII, second part of the book. The shell bears the name of the type-locality, the sampling-station 194 (depth: -160m), « zwischen Cerigo und Cerigotto » (between Kythira and Antikythira]. |
The holotype 13001 in the collection of the Naturhistorisches Museum Wien. Original pictures provided by P. G. Albano, S-M. Schnedl & A. Eschner. « Each whorl has 10 prominent axial ribs, which are not developed equally, but some here and there are remarkably thick and high, surrounded by others smaller than average. In between the ribs and covering them are numerous (more than 20) spiral threads, which look like small grooves under the microscope. Small pits ornament the threads. They seem to be crossing points of the spiral threads with axial lines which are no longer visible in our specimen (in this regard compare the microsculpture of Scaria funiculata Watson). In contrast to closely related species, the ribs sink into the deep suture in a curved manner, not angled. However, they form a keel around the umbilicus through the thick interconnections of their lower ends. A thick varix is present on the lip and makes it seem duplicated. » – R. Sturany: op. cit. p.9.
