New occurrences of Traquairaspis sp., Oniscolepis? sp., Turinia sp., Cephalaspis (Zenaspis) cf. excellens Wängsjö, Nostolepis sp. and Ischna-canthidae gen. et sp. indet. are recorded from the primaeva Beds. Taken as a whole, the vertebrate fauna of these beds shows a general resemblance to those of the upper part of the symondsi zone and the lowermost part of the leathensis zone in the Welsh Borderland. For this and other reasons it is suggested that the Frænkelryggen Formation should be correlated approximately with the symondsi and leathensis zones of the British ‘Psammosteus’ Limestones Group and that the equivalent of the boundary between these zones should be placed either in, or just above, the primaeva Beds.
