New species of Ascidian from the West Indies

The ascidian fauna of the West Indian region is relatively well known as a result of the work of VAN NAME (1902, 1921, 1930, 1945), BERRILL (1932), MILLAR (1962a) and VAN DER SLOOT (1969). During the past few years one of us has carried out extensive collecting in the coastal waters of Jamaica with a view to preparing a faunistic and ecological account of the ascidians of that island. In the course of this work a number of new species have been discovered, which are the subject of the present paper. In addition we propose that Halocynthia microspinosa (Van Name, 1921) be reinstated
