Remark The canaliculate umbilical plug diameter ranges from 0.25 mm to 0.35 mm. The entire shell diameter ranges between 0.4 and 0.85 mm, while the thickness is comprised between 0.23 mm and 0.5 mm; the compression index (thickness on diameter) ranges between 0.55 and 0.58. Chambers increase in breadth through ontogeny. There are 2.5 whorls: 11 chambers in the first whorl,17 in the second and 14 in the last half whorl. The big specimens representing the paratype of Smout (Fig. 2P) shows 31 chambers in the external visible whorl. Diameter of the vertical canals is around 20 micron. Spiral umbilical canals diameter varies from 10 micron to 35 micron. The incomplete spiral interlocular space is produced by the coalescence of some vertical canals. Arguably, these vertical canals communicate the intraseptal interlocular spaces with the spiral umbilical canals of the subsequent whorl. [details]
