Mangelia fordii is a species of sea snail, a marine gastropod mollusk in the family Mangeliidae. [1]
The length of the shell attains 4+1⁄3 mm, its diameter 1+1⁄2 mm.
The ovate-fusiform shell is white. The shell contains 6 whorls, of which 2 smooth whorls in the protoconch. The subsequent whorls are slightly convex. This unpretending little shell has for its chief distinctive characters the 8 rounded ribs and fine spiral striation, and the outer lip is thickened within at a little distance from the acute margin. The small aperture is narrow. The columella shows a small callus. The siphonal canal is very short. [1]
The habitat is unknown.
Beddomeia protuberata is a species of endemic freshwater snail in the family Tateidae, found in northern Tasmania, Australia. The shells look ovate and periostracum yellow with some pustules, length between 2.29 mm and 2.93 mm and width between 2.01 mm and 2.34 mm. Beddomeia protuberata has 1.75 protoconch whorls. Its image of microsculpture is uniform and its wrinkles arranged weakly and helically. The teleoconch of beddomeia protuberata has 2.2 to 2.7 convex whorls, and the ratio of convexity is 0.15 to 0.24. Sculptures of the teleoconch are vague with prosocline growth lines. The margin of the last whorl is evenly circular. The thickness and width of inner lips are medium sizes, and the columellar swelled up prominently. The outer lips of Beddomeia protuberata is prosocline, which means the shell leans forwards compared to the shell’s coiling axis. The width of their umbilicus is between 0.31 mm to 0.51 mm. The umbilicus of female beddomeia protuberata are wider than the umbilicus of male.
