Figure 6E View FIGURE 6

Elongate zooids usually pale orange in color, both siphons short, close together at anterior end of body. Orange band around siphons, blue spots in life between the siphons.

#2640, longest zooid 10 mm. Orange band around siphons, blue spots in life, not visible in fixed zooids. No orange spots scattered on body wall as in #4613. Sixteen rows of stigmata on right, 17 rows on left. About 50 oral tentacles. Cluster of poorly developed testes in curve of gut in some zooids.

#4613, zooids 6 mm in length; a few scattered orange spots on body wall visible through the transparent tunic. Seven oral lobes, six atrial lobes. Sixteen rows of stigmata on right, 15–16 on left (posterior-most row is dividing). A cluster of immature testes in curve of gut.

Distribution: Sri Lanka, Australia, Bahrain, Thailand, South Africa, Red Sea, Israel (Mediterranean).
