Figs. XXV and XXVI. Surface views of eggs of Cionn intestinalis

Copied from Castle's figures 5T and 58 (1896). Fig. XXV represents an anterior view ; Fig. XXVI a posterior one of the same egg. Tlie orientation and cell-lineage, according to Castle, are indicated by the designations of the cells in that half of the egg under his name; the designations of the corresponding cells in the other half of each figure shows the system of orientation and cell-lineage adopted in this paper. Owing merely to differences in nomenclature the cells in the right half of Fig. XXVI are designated by the letter D, those on the left by the letter B. Everywhere lower-ease letters designate cells of the animal (maturation) hemisphere; capitals, cells of the hemisphere opposite the maturation pole. The equator lies between the cells designated by lower-case and capital letters.
