ABSTRACT A species of the right-eyed flatfish family Samaridae, Samariscus inornatus, was collected from the Gulf of Elat. This species was previously known only from three syntypes from the Gulf of Aden. The species is redescribed and a key to the species of Samariscus is presented. One specimen of the pleuronectid Pleuronectes platessa was collected from the Gulf of Elat. This species is distributed from the White Sea, along the coasts of Europe, to the northern area of the Atlantic coast of Morocco and the western and central areas of the Mediterranean Sea. The Adriatic Sea is the eastern limit of this Mediterranean distribution. It appears to be highly probable that this species has been introduced into the Gulf of Elat via ballast water of ocean-going vessels. Since only one specimen was collected, it is not known if this species is established in the Red Sea.
