Anatomical description: For the anatomical examination I have used the t'pe-specimen of Phellia crassa and a piece of the distal part of Cactosoma ahyssorum (Danielssen has sectioned the lower part), I have, besides, more closely examined certain parts of the specimens from the other stations. The ectoderm of the physa is rather liigh and contains nematocysts of the same size as those of the scapus. The ectoderm of the scapus is a little lower and provided with a cuticle and conspicuous '/ffl/caw/jfl-papillae'. It contains typical nematocysts lo—16 x 2—2,5 in size. The ectdderm of the capitulum is devoid of a cuticle and is higher than the ectoderm of the scapus. Its nematocysts are very numerous and nmch larger
