Excerpt from A Monograph of the Gymnoblastic or Tubularian Hydroids, Vol. 1 of 2: In Two Parts, I. The Hydroida in General, II. The Genera and Species of the Gymnoblastea The additions which the last few years have made to our knowledge of hydroid morphology have necessitated the introduction of new terms. Such terms as I have found it necessary to construct have been made as far as possible etymologically significant of the ideas intended to be expressed by them, while I have endeavoured to define them with a rigidity which may allow of no ambiguity in their application. The advantages to be derived from a significant and rigidly defined terminology are great, for it not only facilitates the recording and communication of scientific truths, but it even becomes, like the symbols in algebra, a direct aid in original research.
