This historic book may have numerous typos and missing text. Purchasers can download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1893 edition. Excerpt: ...of 5.5c'." Most of the specimens (PI. xxv, Fig. 47) are only partially contracted, allowing the tentacles to partially protrude, but in some they are entirely concealed from view. The base is flat, marked with fine radiating lines, and has the lim-bus folded back over its edges in all the specimens. The column is nearly cylindrical, and slightly smaller above than below. Its wall has a firm, parchment-like consistency, and is variously corrugated, in part owing to contraction. In the more fully expanded specimens the surface has somewhat the appearance which beaten silver or other soft metal presents, while in others the corrugations may be sufficiently pronounced as almost to justify the designation of irregular tubercles. There are, however, no indications of verrucae..Below the margin the mesogkea is rougher than elsewhere, and is raised into irregular ridges. The column wall has a snowy white appearance, the ectoderm in all the specimens having almost disappeared; the fragments of it which remain in some specimens seem to indicate that it was of a pale, brownish-purple color. The sphincter (PI. xxv, Fig. 51) is well developed and extends a considerable distance down the column wall. In its upper part it does not occupy the entire width of the column wall, but lies throughout its course nearer the endodermal surface than the ecto-dermal, its cavities passing, in fact, directly into the ordinary circular musculature of the endoderm. It does not expand suddenly above, but its upper part, though larger than the middle region, tapers off very gradually as it is traced downwards. In its upper part the closely packed muscle cavities show a tendency to be arranged in longitudinal bands (PL xxv, Fig. 52) separated from one another by streaks of nearly...
