What were the mythological women called who lured sailors to their death?

Sirens. The sirens were merlike females that used their songs to draw sailors to the deaths. The most popular myth that features the sirens is The Odyssey in which Odessues stuff cotton in all his crew members ears except his own so that they would not be attracted by the sirens' song. A siren is a monster that is either a women of the water (mermaid) or a bird-like creature. These monsters would use their voice to put men into a trance of utter devotion and false love.

It was no one siren. There was a group of them, no individual names.
