ResumoThe Cambrian Tethys Sea is here understood as the northern seas of the Peri-Gondwana belt.In the early Cambrian period there were the Mediterranean subprovince in the west and the Zagros-Himalayan subprovince in the east of the Redlichian province (1987) .In the latter Redlichia was most characteristic of its fauna as represented by Redlichia noetlingi, R. chinensis and R. nobilis which are found in the Zagros Mountains in South Iran, Salt Range in Pakistan and Spiti in the Himalayas.The former subprovince can be distinguished from the latter by such endemic genera as follows:Redlichops in the Dead Sea Region, Sardoredlichia, Nebidella, Bornemannaspis and Iglesiella in Sardinia, Italy and Galloredlichia in the Montagne Noire, South France.Spain and Morocco are the contact areas of the Redlichian province with the Olenellian province.Realaspis and Perrector in Spain, Pareops and Clariodia in Morocco and Lemdadella of these two areas are indigenous redlichid genera.The Vila Boim fauna in Portugal devoid of redlichids belongs to the Olenellian province (Teixeira, 1952) .Redlichia ( ?) sp.inlet. is reported to occur in Mauritania to the South of Morocco (Poulsen, 1960).In the Asiatic continent there were the Himalayan geosyncline in the South and the Mongolian geosyncline in the North during the Palaeozoic era.Kapingaspis Chang, 1965 from Sinkiang is an endemic redlichid in the latter geosyncline.In the Khobdo region, Western Mongolia Eccaparadoxides oelandicus, E. insularis and E. mongolicus show that the Paradoxidian sea transgressed easterly as far as Central Asia in the early Middle Cambrian age (Dumicz, Tomozykowa and Wojcik, 1970).Likewise, Paradoxides (Eccaparadoxides) remus, P. (E.) cf.pradoanus and P. (s.l.) pentagonalis, n. found in the Sosinsk Formation in Southeast Turkey (Dean, 1982) reveal the easterly extension of the Bohemian-Mediterranean sea in the Middle Cambrian period.Pardaihania, Solenopleuropsis and Chelidonocephalus are three Mediterranean genera.The former two are found in Southeast Turkey.The last reached as far as Iran (King, 1937) and probably died out with Chelidonocephalus ?(Farsia) in Afghanistan at the beginning of the Upper Cambrian age ( Wolf art, 1974).Hundwarella Reed, 1934 was founded on H. personata from Kashmir.H. haimantensis (Reed) is the key to the Trilobite Horizon 6 at the top of the Parahio series in Spiti.This genus is well represented in the Manchuriella beds in the Changpoung series on the Yunnan-Tonkin border (1944).As pointed out already (1955), Anomocarella (Entorachis) memor Reed from the Trilobite Horizon 5 is closely related to A. (E.) brevi f rons from South Korea.These
