# Colus

Colus (lat. colus, distaff) is a genus of sea snails, marine gastropod mollusks in the family Colidae, the true whelks and the like.

## Evolution

Colus is related to the New Zealand genus Austrofusus.

## Taxonomy

The name Colus is not available from Humphrey, 1797 (published in a work placed on the Official Index). Most recent authors use the name Colus Röding, 1798 for the genus instead of Sipho Bruguière, 1792. Iredale (1919b) mentioned: "This name cannot be defended by anyone" and was rejected by the ICZN (Op. 21). Also Tritonofusus Beck, 1874 cannot be used because of the rules of priority.
