Aegista oldhami is a species of air-breathing land snails, a terrestrial pulmonate gastropod in the family Camaenidae. [1]
The diameter of the shell attains 13 mm.
The fairly large, rather thin shell is orbiculately depressed and widely umbilicate. It is greenish brown. The spire is depressedly conoid and has an obtuse apex. The suture is impressed. The shell contains six to seven narrow whorls. These are slowly increasing and subplanulate. The sculpture consists of closed raised striae, that are irregularly oblique and flexuous, and fine decussating spiral lines. The body whorl is shortly and rapidly descending in front and obtusely angulated above the periphery. The aperture is oblique and lunately rounded. The base of the shell is convex and angular around the umbilicus. The thin peristome is a little expanded with the margins approaching. [2] [3]
Aegista is a genus of air-breathing land snails, terrestrial pulmonate gastropod mollusks in the family Camaenidae.
Amphidromus is a genus of tropical air-breathing land snails, terrestrial pulmonate gastropod mollusks in the family Camaenidae. The shells of Amphidromus are relatively large, from 25 mm (0.98 in) to 75 mm (3.0 in) in maximum dimension, and particularly colorful. During the 18th century, they were among the first Indonesian land snail shells brought to Europe by travelers and explorers. Since then, the genus has been extensively studied: several comprehensive monographs and catalogs were authored by naturalists and zoologists during the time period from the early 19th to the mid 20th centuries. Modern studies have focused on better understanding the evolutionary relationships within the group, as well as solving taxonomic problems.
