Interarea

It is shown that an improvement of interarea transport facilities may encourage trade and as a consequence decrease the disparity in area size.

Finally, as stated earlier, note that these adjustment factors can be used to add back to the characteristics-adjusted indexes the influence of variables that an analyst does not wish to remove in making interarea comparisons.

Nevertheless, significant interarea differences in patterns of rights creation or in the distribution of property will not be reducible to differences in rates of testacy.

The brachiophore or brachial process is a simple, somewhat flat blade located at the notothyrial margin and underlying the notothyrial edge of the interarea.

In one sense the interareas, planareas, and palintropes are genetically the same in that they are all surfaces resulting from increment to the posterior margin.

The posterio-lateral socket ridge lies between the socket and the interarea (pl. 2, figs. 9b, 13b, 16b). The posterio-lateral socket ridges are accommodated by grooves in the hinge teeth of concavo-convex species or pockets between the hinge teeth and the interarea of resupinate species.

Pedicle valve with well developed sulcus; height and concavity of interareas highly variable, apsacline to catacline, rarely slightly procline.

Spiriferides tend to have highly biconvex shells, with well-developed radial costae and a large interarea on the ventral valve.
