Rank: Species

Current identification/main database link: Subbotina angiporoides (Hornibrook 1965)


Original Description
"Test of medium size, fairly thick-walled, non umbilicate, consisting of three tightly coiled, strongly embracing whorls with usually 3.5 chambers in the final whorl; surfaces fairly coarsely punctate and reticulate. The chambers are strongly embracing, very strongly inflated, tending to be elongated along the radial axis in some specimens; and they increase rapidly in size with growth; sutures shallowly incised. The last chamber is variable and in most adult specimens it is more embracing than the penultimate chamber, with its inner border and apertural lip covering the sutures in the middle of the ventral face; in some it is large and swollen and often constricted near the aperture; in others it is elongate and constricted in the middle. The aperture is usually a low slit bordered by a thick lip, opening into the depressed median ventral area, but it varies according to the variation in the shape of the final chamber and in some specimens it extends from the umbilical area for some distance below the anterior face of the final chamber. "Dimensions.- The greatest diameter of the holotype is 0.45 mm. In the type sample most adults are within the range of 0.45 mm. to 0.55 mm. in the greatest diameter.
