C, part of cone. (Northampton Museum; nat. size.) cone (in the Northampton Museum), of the same type; this specimen shows the appearance of the scales in end-view (C), in surf ace-view (A), and as seen from the proximal end with the seed-cavity (B). In fig. 739, A, the base of a seed is seen projecting from the middle of the laterally expanded scale. An oblong-ovate cone described by Carruthers^ from the Coralline Oolite at Malton, Yorkshire, as Araucarites Hudlestoni is probably another example of this species: in one of the specimens of A. Hudlestoni in the York Museum a broad central region is occupied by a mass of pisolite to which numerous cone-scales are attached. The scales are shown in section and in several of them there is a single seed lying in a cavity occupying the proximal end of the scale precisely as in ^. ooliticus. It is possible that A. ooliticus is specifically identical with A. spJiae- rocarpus; it is at least a closely allied type. The specimen figured by Lindley and Hutton^ as Strobilites Bucklandi appears to be indistinguishable from A. ooliticus. Similar cones are illustrated by Araucarites Cleminshawi Mansell- 1 Carruthers (77); Seward (04) B. p. 133. ^ Lindley and Hutton (34)
