ON THE CLASSIFICATION OF REDLICHIACEA,WITH DESCRIPTION OF NEW FAMILIES AND NEW GENERA

W.T.CHANG (Institute of Geology and Palaeontology,Academia Sinica)  
In the present paper,the classification of Redlichiacea is discussed and revised on the basis of the Chinese new material.To begin with,the writer is inclined to emphasize asthe bases of the classification the following characteristics:1)the pattern of facial su-tures and the position of the pre-ocular facial line on the pre-ocular limb,2)the outlineof glabella and the glabellar furrows,3)the length of palpebral lobes and the widthbetween its posterior end and the glabella,4)the presence or absence of pits and tuberclesin the marginal furrow,5)the length and position of the eye ridge,6)the breadth andstructure of the brim(e.g.mesial ridge and other structure),7)the length and width ofthe posterior lateral limb,8)the shape of the free cheek and the position of the genalspine(normal or advanced),9)the position of the axial spine on the thoracic segment,10)the shape and size of the pygidium,11)the presence or absence of the intergenalangle(β angle),12)the shape of rostral plate,13)the shape of the hypstoma,and 14)the shape of the thorax,etc.So far as the writer knows,Latiredlichia is no more than a subgenus of Redlichia,Saukiandops and Archaeops are two synonyms of Pararedlichia.The NeoredlichiidaeHupé,1933,has been emended as a subfamily,including Neoredlichia and Leptoredlichiain the Redlichiidae,because Neoredlichia is a genuine Redlichid.Redlichaspis,Bulaiaspisand Redlichina seem to bear no relation to Redlichia.Mesodema is a synonym of Red-lichia because the pre-ocular facial line is a common feature in most species of Redlichia.Pareops is a member of Resseropidae,which has been proposed by the writer for agroup of Lower Cambrian trilobites found from Spain and Morocco.Eops and Pseudo-saukianda are members of Resseropidae and Saukiandidae respectively.The Yinitidae is considered as a subfamily in the Drepanopygidae.The Redlichiidae,Abadiellidae,Dolerolenidae,Gigantopygidae may have developedfrom a common trilobite stock in the pre-Cambrian.The Drepanopygidae,Mayiellidae,Resseropidae,and Saukiandidae claimed to be most probably descendants of earlyknown Redlichiidae.The classification of the Redlichiacea proposed by the writer is givenin the Chinese text of the present paper.The diagnosis of 15 new genera(including subgenera),3 new families(includingsubfamily),and supplemental notes on 5 old and important genera are shown as fol-lows:Superfamily RedlichiaceaFam.Redlichiidae Poulsen,1927Suhfam.Redlichiinae Poulsen,1927Gen.Redlichia
