The radii are, as stated, extremely narrow, and very remarkable from their smooth rounded edges; their septa are barely denticulated.
In Chelonobia, they enter between the radiating septa in the thickness of the walls: in Coronula diadema, they extend from over the basal membrane into the six large square chambers (Pl.
The parietal tubes are not large; they are generally crossed by transverse septa in their uppermost part; but they are sometimes almost solidly filled up by dark shelly layers.
A slight furrow in the compartment, against which each radius abuts, is generally marked by the septa and their denticuli.
In some of the thinner specimens, the parietal tubes are large, and the longitudinal septa are furnished with small, sharp denticula.
Hameri, the walls consist only of the outer lamina with longitudinal ribs, no inner lamina having been formed; the ribs here evidently answer to the longitudinal septa in the foregoing species.

Wilde distinctly states that it was "divided into separate compartments by septa or divisions that intersected one another in different directions.
The termination of such septa on the surface would give rise to the appearance of dermal plates or scutes, or the septa may even have been attached to something of the nature of dermal plates.
This sheet is split into segments or myotomes by transverse connective tissue septa or myo-commata; each myotome corresponding to one spinal segment.
This is expressed roughly on the external surface of Amphioxus by the direction of the connective tissuesepta between the myotomes (cf.
Unquestionably, septa occur in typically developed varicella chambers, similar to those seen in variola--a pathological fact which is the corner-stone of the doctrine relating to the unity of the two disorders.
Between these chambers the separating strata of epithelia are compressed so as to form septa or partition walls.

The septa of the two sides do not, in the first place, quite meet along the median dorsal or ventral lines, and in the second place they only penetrate the yolk for a certain distance.

By stage O it begins to be divided into a number of separate areas or lobes by septa formed of nucleated fibres.
The external layer of columnar cells has now vanished, and the gland is divided up by the ingrowth of connective-tissue septa into a number of areas or lobules--the rudiments of the future follicles.
Along the line of insertion of each of these septa there is developed a considerable space between the somatic and splanchnic layers of mesoblast.
Their distal ends do not, however, remain close to the peritoneal membrane, but pass outwards along the intermuscular septa till their free ends come into very close proximity with the skin.
The organs are placed at the bases of the feet in two lateral divisions of the body-cavity shut off from the main central median division of the body-cavity by longitudinal septa of transverse muscles.
In the specimen figured the following is the arrangement: The ovary lies rather to the dorsal side in the central compartment of the body-cavity, and is attached to one of the longitudinal septa separating this from the lateral compartment.
The septa of the body are provided with a fairly rich capillary network.
The septa so formed, which were first described by Barrois, are not complete.
A capillary network following the septa is present.

Each arm is divided by seven to eight convex transverse septa into eight to nine simple, broad chambers.
More seldom the tubes are divided by horizontal septa into a series of chambers (Medusettida, Pls.
But these aspinal compartments and the separating septa are not new productions of the Diploconida, but are inherited from their ancestral family, the Hexalaspida (compare above, p.
The inner communication of the cupolas or chambers is more or less free, the lattice-work of the separating septa between them commonly remaining more or less imperfect, or represented only by some isolated beams or meshes.
Each arm is divided by eight transverse septa into nine simple joints or chambers of the same height; the breadth of the distal chambers increases rapidly.
But the building of these chambers and of their septa is by no means so regular and complete as in the greater number of turbinoid Foraminifera.

In others the peripheral ends of the septa are united only by bars or trabeculae, so that the theca is perforate, and in many such perforate corals the septa themselves are pierced by numerous perforations.
As growth proceeds new septa are formed simultaneously with the new couples of secondary mesenteries.
The trabeculae are united together by these thickened internodes, and the result is a fenestrated septum, which in older septa may become solid and aporose by continual deposit of calcite in the fenestrae.

Hence in corals in which there is only a single cycle of mesenteries the septa are correspondingly few in number; where several cycles of mesenteries are present the septa are correspondingly numerous.
In many of these so-called rugose forms thesepta have a characteristic arrangement, differing from that of recent corals chiefly in the fact that they show a tetrameral instead of a hexameral symmetry.
