Cystiscus angasi is a species of very small sea snail, a marine gastropod mollusk or micromollusk in the family Cystiscidae.[2]
Description
The length of the shell attains 1.8 mm.
(Original description in Latin) The shell is very small, subovate in shape, and smooth. It is relatively thin, translucent, and possesses a brilliant luster with a milky-hyaline color. The spire is sufficiently conspicuous, though it is somewhat flattened.
There are three whorls, which are separated by a suture that is not very distinct. The body whorl is large, nearly equaling the total length of the shell, and it is tapered at the base.
The aperture is elongated and narrow. At the base, the columellar margin is not very conspicuously folded, while the outer lip is thickened and milky-white. [3]
Distribution
This marine species was found off Port Jackson, Australia.
