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]
