Type locality.

"Ad Buket Pondong".

Material examined.

Malakka: Bukit Pondong (Perak), SMF 109493 (lectotype, designated by Zilch 1957); Same data, SMF 109494 (2 paralectotypes).

Diagnosis.

Protoconch rather low, without obvious spiral lines, the granules following a near spiralling arrangement, but not at all similar to the multiple, narrow spiral striae typical to most Metalycaeus species; R1 with rather regular ribs and strong spiral lines; R2 extremely short, with only ca. five ribs which are blunt (probably bent?). Operculum unknown.
