The material treated here comprises 7 species, one of which represents a new genus. Sipunculoidea: Sipunculus titubans Selenka & De Man, 1883; Phascolosoma scolops (Selenka & De Man), 1883; Phascolosoma agassizi Keferstein, 1866; Aspidosiphon mülleri Diesing, 1851; Aspidosiphon venabulum Selenka & De Man, 1883; Aspidosiphon hartmeyeri W. Fischer, 1919. Echiuroidea : Platylobostoma glaucum n. g., n. sp. Of these species Ph. scolops, Ph. agassizi, Aspidosiphon mülleri and A. venabulum were previously known from West Africa. Sipunculus titubans was only known as the variety dipthychus from the area under consideration. New to the area is Aspidosiphon hartmeyeri, which hitherto was known only from the type locality: Southwest-Australia; the material of this species has allowed a closer examination than that of W. Fischer's material. Of special interest is the find of two specimens of an echiuroid, which represents a new genus, which has been called Platylobostoma on account of the presence of two flat lobes bordering the ventral side of the mouth instead of the otherwise so characteristic proboscis.
