Some Ascidians from the Caribbean

This paper deals with a small collection of West Indian ascidians (class Ascidiacea: sub-phylum Tunicata) made by Dr. P. WAGENAAR HUMMELINCK in 1930, 1948/49, and 1955, to which several specimens taken by Dr. J. H. STOCK in 1958/59 were added. The material collected by Dr. HUMMELINCK (indicated with Station number) has been deposited in the State Museum, Leiden, and that collected by Dr. STOCK in the Zoölogisch Museum, Amsterdam. TRAUSTEDT (1882, 1883), SLUITER (1898), and VAN NAME (1902, 1921, 1924, 1945) have already described ascidians from the West Indies, and the following 24 species have been recorded from the Netherlands Antilles, all from Curaçao
