Specific Character. Column cylindrical, short; conchula cut into five shallow lobes ; tentacles crossed by dark wavy bands. Peachia undata. GossE, Annals N. H. Ser. 3. i. 418. GENERAL DESCRIPTION. Form. Column. Cylindrical, roiinded below, slightly fluted, about twice as long as the diameter of the disk; terminating below in a central perforate depression, around which the skin is much puckered, and minutely cor- rugated. Surface wrinkled, both transversely and longitudinally, espe- cially when contracted. Margin distinctly angular, sometimes forming a very low parapet. IHsk. Smooth, flat, or rising with an even and very gentle elevation from the foot of the tentacles to the edge of the mouth; marked with twelve radii forming so many fine lines. Tentacles. Twelve, in one circle, marginal; thick and rounded at foot, tapering regularly to the tip, which is obtusely pointed; transverse section sub-ovate, the diameter from side to side exceeding that from back to front. By irregular contraction, they sometimes become slender and cylindrical, often with the tip clubbed or knobbed. They are generally carried widely expanded horizontally, with the tips arching downwards, like a twelve-rayed star. Mouth. Descends abruptly from the disk with a sharp angle, but which can scarcely be called a lip, as it is not thickened. It is protrusile at the will of the animal, when ordinarily it embraces the exserted gonidial groove, and displays a number of plicae at its edge. Conchula. The groove is greatly de- veloped ; its edges are in contact imtil conchula of r. undata about one-sixth of an inch from the tip, (ma/jnijied). where they separate, and turn over with a scroll-like expansion, the margin of which is cut into five shallow teeth, as follows:—one terminal and two.
