Species Candeina nitida d'Orbigny 1839 | ||||||
|
||||||
Diagnosis / Definition: | ||||||
Kennett & Srinivasan (1983): Test medium, relatively high trochospiral, chambers globular to hemispherical, increasing regularly in size. The final whorl consists of three chambers, sutures radial to curved, depressed; surface smooth, microperforate with extremely fine perforations distributed irregularly . Primary aperture not visible in the adult;numerous small, rounded secondary apertures, bordered by a rim, almost completely surround the later chambers. |
||||||
Discussion / Comments: | ||||||
Kennett & Srinivasan (1983): C. nitida is easily distinguished by its microperforate, trochoid test with sutural supplementary apertures completely surrounding the later chambers. Bolli & Saunders (1985): This easily recognizable species with its shiny, porcellaneous looking wall is tightly coiled with usually 3 chambers per whorl and a completely closed umbilicus, giving it a somewhat subglobular appearance. Numerous small circular to elongate apertures often surrounded by a rim are aligned along the sutures of the chambers of the last whorl in particular, but also occasionally along sutures of the penultimate one. |
