FIG. 3.—Ventral portion of skeleton of same specimen as fig. 2, also from ventral side.

The skeletal structure of this ventral region consists mainly of a branch from each primary lateral rod, which sweeps around ven- trally and may even cross that of the opposite side in the median line (fig. 3). These give out similar anastomosing branches, which, how- ever, never attain the high degree of complexity characteristic of the skeleton in the dorsal region. The network becomes finer just beneath the ectoderm, into which it projects innumerable short, spine-like processes. The skeletal supports of the arms are each made up of 3.
