GEORGE WILLIAM HUNTER, Jr. In the fall of 1897, while working upon the morphology and finer structure of the nervous system of Cynthia partita (Ver- rill), after noting the papers of Vo...n Lenhosseck ('95), Dehler (•95), McClure ('96), and Miss Lewis ('96), I was led to look for the centrosome and sphere in the cells of the central ner- vous system. I was directly prompted to this investigation by an examination of the plates of Van Beneden and Julin's ('84) early paper on the central nervous system of the Ascidians. In PI. I, Figs. 2 and 3, these authors represent ganglion cells with excentric invaginated nuclei. Careful study showed the same thing to be true for the ganglion cells of Cynthia, I was, however, not immediately successful in staining the centro- some, although later material killed in more favorable reagents showed that a structure homologous with the centrosome and sphere of authors exists in the tunicate ganglion cell.
