Alycaeus (Alycaeus) vulcani - Kobelt 1902: 352.

Type locality.

"on the upper portion of the isolated peak of Puppa, an extinct volcano lying ca. 40 miles E. S. E. of the town of Pu-gán in the territories of the king of Ava".

Material examined.

Ava, Burma, MCZ 135705 (1 shell, labelled as syntype); Puppadoung, ex coll. Theobald, NHMUK 1888.12.4.939-942 (4 shells, possible syntypes); Puppa, Ava, Burma, coll. H.F. Blanford, ex coll. auctoris, NHMUK (8 shells, possible syntypes); Puppa Hill, Ava, leg. Blanford, Crosse coll. 1899, Sykes coll. 1954, NHMUK (2 shells, possible syntypes).

Remarks.

Protoconch rather elevated, without spiral striation; R1 with elevated, regular, sharp ribs and without spiral striation; R2 long with widely spaced, sharp ribs.

The absence of spiral striation on the entire shell is unusual for Chamalycaeus , and characteristic for Dicharax . However, the general shell shape, the strong, equidistant ribs, and the elevated protoconch suggests that this species belongs to Chamalycaeus .
