The a-nematocysts of the column were generally more thin in the distal end, in the specimens i and 3 sometimes a little curved and with indistinctly visible basal part to the spiral thread. In the specimen 2, the maceration preparations of which are a little unreliable in consequence of the bad state of preservation, the basal part of the spiral thread was visible, most of the capsules were destroyed here and only the rib-like basal part left. The b-capsules of the column were of equal breadth. In the a-capsules of the actinopharynx the basal part of the spiral thread was more or less visible, the a-capsules were broader in the basal end, the b- and c-capsules were in all places equally broad. The main part of the capsules in the tolumn and the actinopharynx consists of a-capsules, the b- and c-capsules were very sparse. The nematocysts of the ten- tacles were rather sparse, the spirocysts numerous. The a-capsules of the actinopharynx vary a little in size, I must, however, mention that the size of the capsules in the actinopharynx is unreliable, according to the strong compression of this part; it is possible that one part of the capsules belongs to the filaments. The size of the nematocysts and the spirocysts besides agrees well in the four specimens. The mesogloea of the column is not thick but very fibrillated, the endoderm is thin. The endo- dermal cir
