In no animal of this orderis there anything like an internal skeleton, the whole body being gelatinous. In Cydippe, however, the bandsupon which the cilia are seated are of firmer texture than the rest. Many of these animals are very active intheir movements, contrasting strongly with the sluggish Pulmograda. The Cydippe pileus, a species very abun-dant on many parts of the British coast, is particularly energetic. It is provided with two long tendril-likefilaments, arising from the bottom of two cavities in the posterior part of the body ; and each of them is furnishedwith lateral branches. These filaments can be entirely retracted within the two cavities of the body, so that.
