Description and validation of the cyathaspids (Vertebrata, Heterostraci) from the Red Bay Group of Spitsbergen, previously introduced and/or described by Kim (1930, 1932) and Kiax & A. Heinz (1935). The following species are defined: Dinaspidella robusta; Irregularempis hoeli, I. mirabilis n. sp. Poraspis Polaris, P. breuis, P. rostrata; Homalaspidella nitida; Anglaspis insignis, A. heintzi n. sp., A. elongata n sp.; Ctenaspis dentaia and C. cancellala. The biostratigraphy of these taxa is briefly reviewed. The Spitsbergen cyathaspids are mainly compared with the Canadian Arctic forms, for one of which the new name Dinaspidella elizabethae is introduced. 0 Spitsbergen, Lower Devonian, Cyathaspidiformes (Agnatha), systematic revision, new tam
