Lessepsian

The preposterous demands urged in connexion with the bombardment of Alexandria are the youngest, as the Lessepsian conception of the rights of the Canal Company is among the oldest, fruits of the same general ideas.

The Polychaeta Cirriformia semicincta, Branchiosyllis uncinigera and Spirobranchus giganteus, considered by [Lucien] Laubier (1966) to be lessepsian immigrants, are more probably circumtropical species, which are warm water relics along the Levant coast, where Laubier found them, and not necessarily immigrants through the Suez Canal.
