Agaronia griseoalba is a species of sea snail, a marine gastropod mollusk in the family Olividae, the olives.

(Original description in German) The spire is relatively short, approximately one-third of the total shell length.

The initial part of the body whorl on the ventral side shows vertical rows of pale brown spots, which become increasingly faint or disappear entirely towards the end.

There are no distinctive markings under the suture, but there is a pale reddish-brown spot near the upper end of the aperture wall.

[2] This marine species occurs in the Mexican part of the North Pacific Ocean;[1] also off Costa Rica, Panama, Nicaragua and El Salvador.
