Emarginula is a genus of small keyhole limpets, marine gastropod molluscs in the family Fissurellidae. [1]
The oval shell is obliquely conical with a backward-pointing recurved apex. There is a deep incision in the anterior margin. A distinct anal fasciole extends upwards from this incision. The surface is latticed, sculptured with radial ribs. There is no septum inside. [2]
The radula has a dental formula of [many].1.4.1.4.1.[many], [3] with a wide, rectangular, acuspate rachidian tooth. [4] The various genera have a few dozen rows of teeth. [3]
