Book Description
Excerpt from A Treatise on Zoology, Vol. 5 Closely related as the different forms of the Mollusca are, they exhibit a great variety in external aspect, chiefly because the tegumentary layer, consisting of epithelium, connective tissue, and muscle, is exceedingly plastic, and gives rise to outgrowths, appendages and expansions of the most various kind. The diversity of form is further increased by concrescence of the various out-growths of the body, either with one another, or with adjacent structures; such concrescences being exhibited by the mantle edges, the lobes and margins of the foot, the gills, and other organs.
