in thickness. Several colours have been found, the commonest being beige-brownish. However, whitish, yellowish and reddish colonies are also observed. In all cases the colony organisation consists of circular zooid systems with one common cloacal aperture placed in depressions of the colony surfaces and separated by elevated ridges of tunic. Sometimes the systems are elongated with more than one aperture. The tunic is strong and consistent. In reddish colonies the colour is intense in the zooid systems (with pigment concentrated in the thoraces) and fades in the ridges in-between.

. The thorax has a six-lobed oral siphon, and a narrow atrial opening facing the first two stigmata rows. There is an undivided atrial languet in the anterior rim of the aperture. When the zooids are contracted, minute denticulations are visible in the posterior part of the atrial aperture. There are from 11 to 14 stigmata rows (most often 12–13), with 15–20 slits per half-row. At each side of the branchial sac there are 14–16 fine longitudinal muscular bands.

They are difficult to count as they are often interrupted, sometimes even substituted by irregular protuberances more or less aligned (particularly so on the side facing the intestine). There is a post-stomach and a mid-intestine in oblique or horizontal position at the lower end of the gut loop. The posterior intestine opens in a bi-lobed anus at the level of the fifth or sixth posterior-most stigmata row.</paragraph>

Some zooids have well-developed gonads, with oocytes adjacent to the digestive loop and male follicles filling the post-abdomen. There are also embryos in incubation in the atrial cavity, up to 6 of them more or less in a row. In red colonies, the oocytes and immature embryos are red in colour. Fully developed larvae are elongated, up to
