Not illustrated. 1862 Excerpt: ...instead of being completely differentiated from them as in the higher types of the vitreous series. That the real position of the aperture is nearly in the centre of the anterior wall of the chamber, is made very apparent by a careful examination of its relations in a section passing through the median plane; its position, however, is always more or less outside of the axis of the spiral, so as to be nearest to the convex border. The elevated septal bands or rows of tubercles, the central umbilical tubercle, the marginal carina or cultro with its radiating prolongations, and the longitudinal ribs or scattered spines with which the surface is beset, are all composed of non-tubular shell substance. No additional feature of any importance is revealed by sections of the shell. Even in the most highly developed examples of it, I have not detected the least vestige of a canal-system; and the wall of each chamber seems to be simply joined-on to that of the chamber which preceded it, so that each septum is formed not of two laminae, but only of a single one. 249. Thus the differences between these two extreme forms reduce themselves to these, --that the axis of growth changes from a straight line to a spiral, that the divisions between the segments cross that axis obliquely instead of transversely, and that the aperture leaves its exactly central position to become excentric. Now, among the varied forms of the Cristellarian type, we meet with every gradation between such as persist in the spiral plan of growth through their whole lives, and such as, after forming one or more convolutions, thenceforth increase along a nearly rectilineal axis, still having their aperture at the convex margin. From these last we pass by an equally continuous gradation (exhibited in the..
