Homologies of the Radiata The body of the Cryptocarpae consists of a disk, of an umbrella or bell-shaped form, the lower layer of which, perforated in the centre, projects from the lower surface in the shape of a longer or shorter proboscis, terminating in various ways in different families. The two layers recede slightly from one another at the base of the proboscis, and form a more or less extensive central cavity, from which arise directly a larger or smaller number of narrow tubes extending to the edge of the disk, where they are united by a similar continuous, simple, circular tube, beyond which the margin of the disk is bent inward in the shape of a projecting veil, more or less closing the space beneath the disk; while from the border, formed by this inversion of the margin, arise, along the circular tube, a larger or smaller number of plain or hollow tentacles, in some families limited to the point of intersection of the radiating and circular tubes, and in others extending around the whole disk. Pigment specks appear upon the base of the tentacles of some; while in others, more complicated eye-specks or auditive vesicles occupy the position of tentacles. In the Phanerocarpae, on the contrary, the lower layer of the disk not only recedes from the upper, but thickens around the central.
