.... Cross-section views of the structure along selected lines joining the 45 locations are shown in Figures 6.17 (east of Ashiya) and 6.18 (west of Ashiya). In each case, the observed phase velocities are assumed to be those of fundamental-mode Rayleigh waves, and the data are analyzed for five layers...

... as compared to other groups. Use of molluscan and other data in this analysis, because it is so much more robust than that for the decapods, would surely have masked any pattern that the decapods may have exhibited. Furthermore, combining distributional data from diverse taxa would seem to imply...
