Abstract
ARECENT issue of the Quarterly Journal of Microscopical Science (vol. 72, pt. 1) is entirely occupied by two memoirs on Tunicata. In the first, on the development of Botrylloides and its bearings on some morphological problems, by Miss Sylvia Garstang and Prof. Walter Garstang, uniformity in the purely ectodermal origin of the Ascidian atrium is established, which finally negatives the homology suggested by Van Beneden and Julin (1887) between the larval atrial canals of Ascidians and the spiracles of Ap-pendicularians.
