Shells from the two sides of the Atlantic: numbers of shells of different sizes (See Table II). - = a, • • • == b, - = c. In Fig. 6 are shown camera lucida drawings of the obverse and reverse aspects of three shells from each locality, the relative height of the spire to the rest of the shell increasing from left to right. The dimensions and proportions of the same twelve shells are given in Table IV, where the ratio - decreases in each group with the increase of the spire component, c. From these figures and tables it will be seen that the amount of variation is much the same in each locality and that it would be quite impossible to sort a mixture of shells from the four places, either on.
