Treatment

Alycaeus crenatus Godwin-Austen, 1871: 90-91, pl. 3, fig. 5.

Alycaeus crenatus - Reeve 1878: pl. 1, species 1, figs a, b; Godwin-Austen 1914: 388-389, pl. 143, figs 8, 8a, 8b.

Alycaeus (Dicharax) crenatus - Kobelt 1902: 366; Gude 1921: 241.

Chamalycaeus (Dicharax) crenatus - Ramakrishna et al. 2010: 57.

Type locality.

"On Burrail Range, N. Cachar, at ca. 5000 feet".

Material examined.

Mokarsa, Khasi Hills, coll. Godwin-Austen, NHMUK 1903.7.1.2642 (2 syntypes). Note that the type locality does not match with the locality of the type sample, but the type locality was clarified in Godwin-Austen 1914 in 1897-1914: 389, and the drawing in the original description is identical with the two syntypes.

Remarks.

Protoconch rather glossy, low, without spiral lines; R1 rather regularly, finely ribbed without spiral striation; R2 relatively short, with regular ribs curved towards the aperture.
