The Transition from Rostro-Carinate Flint Implements to the Tongue-Shaped Implements of River-Terrace Gravels . ideal diagram shown above (fig. 6), it will be seen thatthere is not any very fundamental difference observable. In the ideal diagram thepoint C is immediately under A, while in the other (fig. 9) this is not so. But inboth cases the areas indicated by the numerals 1 and 2 have been removed by flakingafter the flint had been shaped into the triangular form of the rostro-carinateimplement. Altogether this curious, unsymmetrical specimen seems to combine thecharacteristics of a definite double-edged palaeolithic implement, with many rostro-carinate affinities, and the author regards it as an excellent example of a very earlyclumsy palaeolithic implement just emerging, so to speak, from the rostro-carinatestage, and showing in consequence many evidences of its parentage. 7. The Axminster Transitional Specimen (Plate 57, figs. 1-4). There is no need to write very much in reference to this symmetrical palaeolithicimplement from Somerset. The drawings of the right and left lateral surfaces. D Fig. 10. 344 ME. J. R. MOIR: THE TRANSITION FROM ROSTRO-CARINATE FLINT IMPLEMENTS (figs, 1 and 2) demonstrate that in profile it has a marked beak-like appearance, while the views of the ventral and dorsal surfaces (figs. 3 and 4) show that thecutting edges take a straight course from the anterior to the posterior region. Insection the implement is roughly rhomboidal in form, and in fig. 10 it will be seenthat its symmetry is such that the point C is immediately under A as in the idealdiagram above (fig. 6). This specimen is of interest as an example of an earlysymmetrical palaeolithic river-drift implement still retaining the rostro-carinateprofile. Conclusion, The foregoing examination of the seven implements has demonstrated that inearly river-drift times, rostro-carinate implements of a highly evolved type were inuse contemporaneously with the normal pointed, palaeolithi
