Cremnoconchus carinatus is a species of freshwater snail, an aquatic gastropod mollusk in the family Littorinidae, the winkles or periwinkles.[3]
Distribution
This species is endemic to the Western Ghats range,[2][4] in India.[5]
The type locality for this species is streams in Mahabaleshwar Hills, the Western Ghats range, India.[2] It lives about 4,500 feet (1,400 m) above the sea level.[6]
Description
In 1869 Cremnoconchus carinatus was originally discovered and described from a juvenile shell[6] (under the name Anculotus carinatus) by the English naturalist Edgar Leopold Layard in 1854.[2] Layard's original text (the type description) reads as follows:[2]
Anculotus carinatus, Layard.
Shell somewhat globose; axis 5 lines, diam. 4 lines. Spire exserted, short. Whorls inflated, rather square, sharply keeled round the inferior angle, minutely longitudinally striated. Colour dull olive, marked faintly with two or three broad bands of dark rufous-brown, which are very apparent in the aperture; columellar lip white, stained with a light dash of the same rufous-brown on the exterior margin.
Hab. Streams in the Mahakeshwar Hills, Bombay Presidency.
Mus. Cuming.
In 1869, another English naturalist, William Thomas Blanford, moved this species to the newly created genus Cremnoconchus.[6]
In the adult shell the last whorl is angulate below the suture and at the periphery.[6] The shell is imperforate, ovately conical, with the apex eroded.[6] The width of the shell is 5.5 mm.[6] The height of the shell is 8 mm.[6]
