MATERIAL EXAMINED. — Philippines. SW Bohol, Panglao Island, 9°33.45’N, 123°48.56’E, 10 m, 20.IV.1997 ( MNHN A3 CLA 109).

REMARKS

The colony has the typical colour of the species, with yellow rings around the siphons ( Fig. 116A ). The tunic is transparent. Dark blue and almost black pigment, is concentrated in the body wall, and this makes contracted animals opaque. In formalin, the musculature appears white on a purplish background. This colony contains numerous larvae incubated in the oviduct at the base of the cloacal cavity.
