N.Parthenii Giannettasii Eel. 1. No. 31. JULY 1860, I. — Note on the Structure and Terminology of the Reproductive System in the Corynidse and Sertulariada?. By Prof. Allman. IN Professor Huxley's Monograph of the Oceanic Hydrozoa, lately published by the Ray Society — a work which, in accuracy of description, copiousness of illustration, and philosophic treat-ment of its subject, must take its place in the first rank in the literature of the lower groups of the animal kingdom, — the author proposes a terminology, partly special, for the particular groups which form the subject of his memoir, and partly intended to apply to the Hydrozoa in general. The greater part of Prof. Huxley's terminology is, I think, very valuable, and supplies a want long felt in the descriptive phraseology of this section of the animal kingdom; but I am nevertheless unable to coincide with him in that part of his work where he objects to my use of certain terms in the descrip-tion of those parts of the Corynidse and Sertulariadae which are concerned in the function of reproduction. I have given to Prof. Huxley's remarks on this matter that careful consideration to which they are entitled, not only from the authority with which their author's sanction must invest them, but from the excellent spirit in which they have been made ; and it is not because I have any particular affection for my own terms, or would wish to insist on their priority as a Ann, # Mag.
