XXX J. — On Budding in Perophora. By Geoege Lefevre *. While the Johns Hopkins Marine Laboratory was stationed at Beaufort, N. C, during the summer of 1894, I collected material for the purpose of studying the development of the buds of this Ascidian. Perophora viridis, Verrill, was found growing luxuriantly on the wharf-piles, and ample material was easily obtained. My main object in undertaking this work was to compare the bud-development of this form with that of Botri/Uus, as described by Hjort t, and especially to determine, if possible, the origin of the nervous system. * From the 'Johns Hopkins University Circulars,' vol. xiv. no, 119, ])]). 75-77. t Mitth.
