Considering the texture of these singular bodies, their ordinarily bright colour, and their relative position to the generative apparatus, we believe ourselves justified in regarding them as dul(B succenturiatte or the Vertebrate animals. In the Octopodous Dibranchiates the ovary is a spherical sac with thick parietes (I, fig. 226). The ovisacs (2) are racemose or connected in bunches, and attached in the Poulp to a single point of the ovarian capsule, but in the Eledone to about twenty separate stalks suspended from the upper part of the ovary. The ova, when detached from the ovisacs, escape by a single large aperture (3), leading from the anterior part of the sac into a very short single passage, which then divides to form the two oviducts. These tubes, in the unexcited state of the ge- nerative system, are membranous, straight, and of an uniform narrow diameter, except where they perforate a glandular laminated enlarge- ment (4), situated about one-third from their commencement; but, towards the period of ovi- position, the parietes of the oviducts increase in thickness and extent, forming longitudinal folds internally. The laminated glands doubtless serve to pro- vide an exterior covering to the ova, and con- nect them together, thus performing the func- tion of the accessory external glands in the preceding tribe. The oviducts ascend behind the lateral hearts and venous cavities, and open on each side of the mediastinal septum of t
