THE OLD RED SANDSTONE OF BROWN CLEE HILL 267 Genus KUJDANOWIASPIS Stensiti, 1942 Kujdanowiaspis anglica (Traquair) (PL 45, fig. 7 ; Text-figs. 9-15) Localities and material. Three specimens only may be certainly attributed to this species : the external impression of a head-shield from Silvington, Water- fall (600 ft. above " Psammosteus " Limestone) ; the internal impression of the left anterior quarter of the ventral armour from Hoptongate (700 ft. above " Psam- mosteus " Limestone) and an anterior ventro-lateral plate from Rea Brook, New House Farm (650 ft. above " Psammosteus " Limestone). Description. The impression of the skull (; Text-fig. 9) is finely pre- served and on it may be traced the outlines of the component bones and the course of the sensory canals. It may be compared with the sketches of the other known skull-roofs of this species (Text-figs. 10-14) which show the great variation in the shape of the individual plates (see also Text-figs. 42, 43). The second specimen, from Hoptongate (P. 27097 ; Text-fig. 15) shows, mostly as internal impressions, the left anterior ventro-lateral plate, the anterior median ventral plate and part of the inter-lateral plate with coracoid process of a young fish. The whole is only 2-8 cm. long, and the tubercles of the ornamentation are correspondingly fine. It is very much as in Stensio's (1944 : 60, text-fig. 17B) restoration of a Podolian form. The last, from Rea Brook, New House Farm, Neenton, is a very well preserved triangular piece consisting of part of the right anterior ventro-lateral plate with the spinal plate and a very small fragment of the inter-lateral plate ( ; PI. 45, fig. 7). It measures 3-7 cm. across and 2-8 cm. from the anterior margin to the AMV LAVL. Fig. 15. Kujdanowiaspis anglica (Traquair).
