Such parts were seen by Eschscholtz only in some individuals, and on this account he was dis- posed to regard them as ovaries. But Messrs. Qnoy and Gaimard seem to consider it more probable that the minute botryoidal bunches of vesicles, which surround the base of each sucker on the lengthened filaments, (before alluded to as being subservient both to nutri- tion and to locomotion,) are the ovaries.* It does not appear that either Eschscholtz or Messrs. Quoy and Gai- mard saw the ova. In the ciliograda, the ovaries are more obvious. They consist of two or four vesicular organs, each placed between two of the cilia-bearing arches. In cydippe, they are of a red colour, and nearly cy- lindrical shape. The ova are spherical. The parts in the pul- mograda corresponding to the organs just referred to, are eight round bodies, of small size, situated near the margin of the disc, each formed of a vesicle, containing, at its free ex- A portion of the tremity) many minute ovigerous filament hexagonal corpuscules ;. of Diphyes much magnified. there is attached to each vesicle a digitated appen- dix, which seems to be hollow, and to com- municate with the circular vessel. These organs were seen by Gaede and by Miiller in medusa capiltata, and M. aurita, and by Eschscholtz in some species of ci/anca, st/ie- nonia, pelagia, and chrysaora ; Dr. M. Ed- wards has observed them also, at certain seasons, in rhizostoma ; and in carybdea mar- supialis, he found, midway between each pair of pendent filaments, and immediately above a little notch in the margin, four spots of a deep brown colour, each of which appeared, under the microscope, to be formed partly by a minute sph
