Material examined.

Abor Hills, Lat. 29°25, Long. 95°20, NHMUK 1903.7.1.3578 (5 syntypes).

Remarks.

In the original description the subgeneric name Raptomphalus is not used. However, the species is introduced after Alycaeus (Raptomphalus) magnificus , and the characteristically keeled umbilicus is similar in both species.

All four shells were strongly weathered, but the characteristic elevated protoconch was recognisable. Moreover, some indication of spiral striation was visible on both the protoconch and R1, therefore the classification of M. oakesi in Metalycaeus is justified. R2 long, with widely spaced, sharp ribs.
