Synopsis

This paper is a first report on the Echiurids and Sipunculids of Zanzibar, and deals with the material collected by Dr J. D. Robertson during the years 1948–1950 on the shores of Zanzibar, supplemented with a few dredgings. These collections contained two species of Echiurids and eighteen species and varieties of Sipunculids. Of these, one Echiurid (Ochetostoma zanzibarense) and two Sipunculids (Dendrostoma robertsoni and Phascolion robertsoni) are described as new species. Six others are recorded from the area for the first time. The list of species now described from the Zanzibar area contains eight species of Echiurids and twenty-four species and varieties of Sipunculids. Rich as the area is in species, it is even more remarkable for the numbers of individuals, some species being dominant forms in the population.
