With this will cease, for the present, my communications on the Bignoniacece, as I learn from Dr. Seemann that he has re-sumed his inquiries into that family, and is about to publish the results of his investigations. The respect I have for that zealous botanist, together with the desire on my part to avoid contra-vention, and the knowledge that he has long studied the subject, induce me to cede to him the priority. As he has the advantage of consulting collections to which I have no means of access, jnore may be anticipated from his exertions. I reserve to my-self, however, the right of resuming the subject at a future time, and of carrying out ray original plan of defining the limits of the genera and subgenera I have sought to establish upon features hitherto unobserved, and also of illustrating their characters by drawings of one or more species of each group, accompanied by analytical figures of the flower, fruit, and seed. XII. — Observations on British Protozoa and Zoophytes. By T. Strethill Wright, M.D., F.R.C.P.E., Pres. Roy. Phys. Soc. Edin. [Plates III. IV. & v.] On the Reproduction of Ophryodendron *. Ophryodendron abietinum, which I have figured in various atti-tudes in PI. III., has been noticed elsewhere by Claparede and Lachmannf and myself J, several years since; but it was not until the spring of the present year that I was able to discover its mode of reproduction. The animal presents the appearance of an oblong sac filled with homogeneous and finely molecular matter, and is found attached to the corallum of Sertularia ^pumila. From one end of the body or sac arises a proboscis, generally appearing as a short and closely-wrinkled club, but * Read to the Royal Physical Society of Edinburgh, April 24, 1861. t Etudes sur les Infusoires et les Rhizopodes, j)ar Edouard Claparede et Johannes Laclimann.
