GLOSSARY OF TECHNICAL TERMS USED IN PART III.

_Brown body_ A body formed in a zooecium by the degeneration of a polypide as a preparation for its regeneration.

_Cardiac portion_ (of That part which communicates with the the stomach). oesophagus.

_Collar_ A longitudinally pleated circular membrane capable of being thrust out of the orifice in advance of the lophoph.o.r.e and of closing together inside the zooecium above the tentacles when they are retracted.

_Dorsal surface_ (_Of zooecium_ or _polypide_) the surface nearest the mouth; (_of statoblast_) the surface furthest from that by which the statoblast is attached to the funiculus during development.

_Ectocyst_ The outer, structureless layer of the zooecium.

_Emarginate_ Having a thin or defective triangular area (of a zooecium) in the ectocyst at the tip.

_Endocyst_ The inner, living (cellular) layer of the zooecium.

_Epistome_ A leaf-like ciliated organ that projects upwards and forwards over the mouth between it and the a.n.u.s.

_Funiculus_ A strand of tissue joining the alimentary ca.n.a.l to the endocyst.

_Furrowed_ Having a thin or defective longitudinal (of a zooecium) linear streak in the ectocyst on the dorsal surface.

_Gizzard_ A chamber of the alimentary ca.n.a.l situated at the cardiac end of the stomach and provided internally with a structureless lining.

_Intertentacular organ_ A ciliated tube running between the cavity of the zooecium and the external base of the lophoph.o.r.e.

_Keeled_ Having a longitudinal ridge on the dorsal (of a zooecium) surface.

_Lophoph.o.r.e_ The tentacles with the base to which they are attached.

_Marginal processes_ Chitinous hooked processes on the margin (of statoblast). of the swim-ring (_q. v._).

_OEsophagus_ That part of the alimentary ca.n.a.l which joins the mouth to the stomach.

_Orifice_ The aperture through which the lophoph.o.r.e can be protruded from or retracted into the zooecium.

_Parietal muscles_ Transverse muscles running round the inner wall of the zooecium.

_Parieto-v.a.g.i.n.al_ Muscles that surround the orifice, running _muscles_ between the folds of the zooecium in an oblique direction.

_Polyparium_ The whole body of zooecia and polypides which are in organic connection.

_Polypide_ The tentacular crown, alimentary ca.n.a.l, and retractor muscles of a polyzoon-individual.

_Pyloric portion_ That part which communicates with the (of the stomach). intestine.

_Resting bud_ An external bud provided with food-material in its cells, with a h.o.r.n.y external coat and capable of lying dormant in unfavourable conditions.

_Retractor muscles_ The muscles by the action of which the lophoph.o.r.e can be pulled back into the zooecium.

_Statoblast_ An internal bud arising from the funiculus, containing food-material in its cells, covered with a h.o.r.n.y coat and capable of lying dormant in unfavourable conditions.

_Swim-ring_ A ring of polygonal air-s.p.a.ces surrounding the statoblast.

_Ventral surface_ (_Of zooecium_ or _polypide_) the surface nearest the a.n.u.s; (_of statoblast_) the surface by which the statoblast is attached to the funiculus during development.
