high, attached to the substratum by a pale yellow small area. The basal portions of the colonies are burgundy colour while the upper layer of the tunic is semi-transparent allowing the observation of white pigment granules on the oral siphons of each zooid. The test is soft and free of epibionts. The zooids are perpendicular to the colony surface and organized in circular or elongated systems containing up to 25 zooids which converge into common cloacal aperture. The thoraces of the zooids are prominent and located in the uppermost layer of the tunic. Living colonies are easily recognizable underwater by the contrast between of burgundy basal area of the tunic and the white prominent zooids (

There are 15 to 21 thread-like oral tentacles of two sizes, arranged regularly in a single circle. The dorsal tubercle is small and circular, with an aperture of similar form. The four rows of long stigmata are crossed by well-developed parastigmatic vessels. There are about 18 to 21 stigmata in each half row. Three dorsal languets are displaced to the left side of the thoracic midline.</paragraph>

The oval stomach has conspicuous internal longitudinal ridges. Ridges are often curved, somewhat irregular or interrupted, giving a stretch-marked external appearance to the stomach wall. A pyloric gland extends between the stomach and the intestine. The intestine has a constriction situated at a short distance beyond the stomach. The bi-lobed anus opens at the level of the third row of stigmata.</paragraph>
