The adjoining figure is given to express the aspect of Torn, bicostatum when uncompressed. Melocrinus clarkei (Hall) Williams Original The shape of the calyx can not be determined on account of the crushed condition of the specimens, but the shape and number of the plates agree so well with those of M. bainbridgensis H. & \\\, that it is probable that the shape was the same, i. e. broadly turbinate. In size, also, the calyx agrees well with that species. No underbasals appear. The basals are low, wide and pentagonal. The radials are more than double the size of the basals, in hight and width equal, or wider than high. The variation in the shape of this plate, in the several specimens on the one slab, covers the extremes met with in the two species, M. bainbridgensis and M. breviradiatus. The radial is followed by two brachials of smaller size, the first hex- agonal, the second pentagonal and angular above, and each is about equal in hight and width. The second brachial supports two arm plates (still within the calyx), nearly as large as the brachials, irregularly pentagonal and meeting at their inner edges. Of the
