Abstract
Two brachiopod species Discradisca indica (Dall, 1920) and Argyrotheca jacksoni Cooper, 1973, together with Lingula sp., have been identified from the Persian Gulf. These species, added to the two species Terebratulina retusa (Linnaeus, 1758) and Megerlia truncata (Linnaeus, 1767) previously identified by Jackson (1921), and Lingula anatina Lamarck, 1819 by Emig (1988) bring the total to 5 species for the region. The genera Discradisca and Argyrotheca are recorded for the first time from the Persian Gulf. This fauna shows biogeographical affinities to the Indian Ocean and the Mediterranean faunas. The disjunct geographical distribution of Discradisca suggests this genus is a relict of an ancient Tethyan fauna.

Summary
Recent brachiopods had not been recorded from the Persian (Arabian) Gulf until 1921, when J. One specimen he identified as Terebratulina caputserpentis ( retusa) var. On the basis of these specimens Jackson equated the Persian Gulf specimens with the typical Lusitanian forms Terebratulina retusa (Linnaeus) and Megerlia truncata (Linnaeus) from the Atlantic and Mediterranean and cit-. The species Lingula anatina Lamarck was mentioned by Emig (1988) from a depth of 6-16 m in the Persian Gulf but without any details of the exact locality. This report describes and illustrates some of the recently-discovered Persian Gulf specimens, from sediment samples kept in the Forschungsinstitut und Naturmuseum Senckenberg, Frankfurt, and from Eberhard Gischler’s collection Goethe-Universität, Frankfurt), collected during expeditions over the last few years
