The Ciliated Heath (Erica ciliaris), perhaps the most beautiful of the British species, is found only in the West of England, but is really abundant on some of the Devon and Cornwall moorlands.
Of the order Caryophyllaceae our first example is the Ciliated Pearlwort (Sagina ciliata), a small, creeping plant, flowering in May and June in dry places.
Both series of organs consist essentially of a ciliated tube leading from the coelom to the exterior.
The body wall consists of an epidermis which secretes a delicate cuticle and is only ciliated in Aeolosoma, and in that genus only on the under surface of the prostomium.
The intestine is usually in the higher forms provided with a typhlosole, in which, in Pontoscolex, runs a ciliated canal or canals communicating with the intestine.
It leads into a straight alimentary canal whose walls consist of a layer of ciliated cells ensheathed in a thin layer of peritoneal cells.
They pass out through short vasa deferentia with internal ciliated funnels, sometimes an enlargement on their course--the seminal vesicles--and a minute external pore situated on the side of the tail.

The convoluted tubuli continuous with them are, I believe, ciliatedin their proximal section, but I have not made careful investigations with reference to their finer structure.
It is as follows:--When the free swimming ancestor of the Spongida became fixed, the ciliated cells by which its movements used to be effected must have to a great extent become functionless.
The whole embryo first becomes flattened, but especially the ciliated half which gradually becomes less prominent (fig.
The figure shews the amoeboid ectoderm cells (ec) derived from the granular cells of the earlier stage, and the columnar entoderm cells, lining the gastrula cavity, derived from the ciliated cells of the earlier stage.
This difficulty is the invagination of the ciliated cells instead of the granular ones.
This cavity is in communication on the one hand with the lumen of the coiled tube which forms the main mass of the pronephros, and on the other hand with the body-cavity by means of a richly ciliated canal (woodcut, fig.
Though respiration was, no doubt, mainly effected by the ciliated cells, it is improbable that it was completely localised in them, but the continuation of their function was provided for by the formation of an osculum and pores.
The ciliated canal is similar in its relations to the peritoneal canal of such a segmental tube, and the coiled portion of the pronephros resembles the secreting part of the ordinary segmental tube.
One of these halves is formed of about thirty-two large, round, granular cells, the other of a larger number of ciliated clear columnar cells.
In these two considerations there may, perhaps, be found a sufficient explanation of the invagination of the ciliated cells, and the growth of the amoeboid cells over them.
The first is, in its most primitive form, a small transparent creature, with a mouth and anus and a postoral longitudinal ciliated band (fig.
In these the surface-pores are the extremities of very narrow tubes which perforate both layers of the body-wall and then communicate with wider tubes or spaces within, some of which are lined with the ciliated cells above described.
These creatures produce eggs which yield small ciliated larvae that swim about freely for a time, and then settle down and establish stalked colonies as previously described.
The eggs are produced in pouches that communicate directly with the stomach-cavity, and these give rise to little ciliated larvae that are ejected through the mouth, and then swim about freely in the water for a time.
The young of the water-breathers always swim about freely by means of a pair of ciliated lobes or fins, but these remain only for a brief period, after which the animal settles to the bottom for a more or less sedentary existence.
He sat to the last moment doggedly struggling to keep cool and to mount the ciliated funnel of an earthworm's nephridium.
But ciliated funnels come not to those who have shirked the laboratory practice.
This process of absorption is probably accomplished in the interradial or ciliated chambers, more probably in the former, as the latter are generally considered excretory in function.
These cells are arranged around the ciliated chambers in the form of a collar, and from each cell flagella protrude, which are in continual motion.
These ciliated chambers are easily detected in the sponge by means of a microscope, as they appear more highly colored.

The open ciliated funnel or nephrostome at the coelomic end of the tubule serves for the passage outwards of coelomic fluid to flush the cavity of the tubule.
The splanchnocoelic end of this is usually ciliated and is termed a peritoneal funnel: it is frequently confused with the nephrostome.

C, Transverse section of a filament taken so as to cut neither a ciliatedjunction nor an interlamellar junction.
Nevertheless the filament is a complete tube formed of chitinous substance and clothed externally by ciliated epithelium, internally by endothelium and lacunar tissue--a form of connective tissue--as shown in fig.
The microscope shows that the neighbouring filaments are held together by patches of cilia, called "ciliated junctions," which interlock with one another just as two brushes may be made to do.
Their function is chiefly not respiratory but nutritive, since it is by the currents produced by their ciliatedsurface that food-particles are brought to the feebly-developed mouth and buccal cavity.
