A plate enlarged. This specimen consists of the lower part of thetup, and about one inch in length of the column of a Cystidean, which will probably be found to belong to the same genus as the last The plates are somewhat convex e.\terioi'ly,and ornamented with strong rays,which extend from the centre to the angles. At the base a laige six-sided pelvic plate is seen resting on the column. From the width of this plate in proportion to the size of the column, it appears that the pelvis is formed of three plates. The column is round and smooth. The impression upon the stone shows that this indi\i- dual was of the size indicated by the dotted line in the Fig. 9. A specimen separated from the matrix, but crushed quite fiat, aiii broJcen into three pieces, a—the ovarian aperture. Of this species I have only the single specimen iigured. The plates are elevated and smooth in the centre. A low rounded ridge proceeds from the smooth space to each angle. Between these ridges fine stri^ cross from one plate to the other, at right angles to the sutures. The j>elvis consists of three broad penta- gonal plates. The coiumn is round, and formed of very thin plates. The ovarian aperture is nearly on the top of the summit Neither arms nor mouth have been observed. The specimen is separated from the matrix, but crushed c[uite flat, and broken across in two places. These three last described species appear all to belong to a genus ditferent from Comarocystites, and I have therefore dis- posed of them as above, provisionally. When more becomes knowtt about them, it may be necessary to make another arrange- ment AgelacriiiUes. Fig, 10.
