It is a sack-like tunic of white linen, with narrow sleeves and a hole for the head to pass through, and when gathered up round the waist by the girdle (cingulum) just clears the ground.
Over this the priest, robing for mass, puts on the amice, alb, girdle (cingulum), stole, maniple and chasuble.
A rotifer may be regarded as typically a hemisphere or half an oblate spheroid or paraboloid with a mouth somewhere on the flat end ("disk" or "corona"), which bears a usually double ciliated ring, the outer zone the "cingulum," and inner the "trochus".
This typically consists of two concentric zones, the trochus and cingulum, often separated by a groove or gutter which may be finely ciliated; but in several genera of no close affinity, where it is very oblique to the longitudinal axis of the body, it is represented by a general ciliation of the surface (Taphrocampa, Rattulus, Copeus, Adineta).
2, I) and its allies, the trochus being oval with two median gaps, the cingulum, more delicate, and complete.
The cingulum appears to be represented by the margin, usually produced into long petal-like 4 5 6 From Comb.
- Diagrammatic Views of Disks of Rotifers: cingulum continuous; trochus dotted; groove shaded; mouth black.
3, b, d) the cingulum is a mere - contractile hood.
In most rotifers, on the contrary, the trochus is stronger than the cingulum, often lobed, and with some of its cilia aggregated into vibratile styles homologous with the combplates of Ctenophora (q.v.) and the membranelles of ciliate Infusoria (q.v.).
The trochus forms the powerful currents for locomotion, and for the supply of food material, while the cingulum produces a local current round the upper rim of the corona to bring the food particles direct to the mouth, which is displaced through a postero-ventral gap in the trochus to lie behind the disk, just as occurs in the more specialized Ciliata.
There is a dorsal interruption to the disk, in volving both trochus and cingulum and groove in this case the two halves of the disk may be developed in lobes, flower-shaped in Melicerta ringens, but often rounded and projecting like kettledrums. These give a strong impression of two crown wheels revolving in the same sense.
C, ventral view: x', trochus; x, cingulum; other letters as above.
Ment and of the struc ture of the disk to their identification of "trochus" and "cingulum" with the preoral and postoral wreaths of the trochophore larva.
CINGOLI (anc. Cingulum), a town of the Marches, Italy, in the province of Macerata, about 14 m.
The town occupies the site of the ancient Cingulum, a town of Picenum, founded and strongly fortified by Caesar's lieutenant T.
Choeropotamus is a European Oligocene genus with bunodont molars which show a conspicuous basal cingulum in the lower dentition; the first premolar is absent.
(iv.) Trophi uncinate: Flosculariaceae; disk a contractile cup, often lobed, the cingulum of long vibratile cilia, of very long motionless bristles or absent, rarely with an outer zone of fine cilia.
