Description: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 present work contains the result of many years' study of the remarkable group of animals to whose elucidation it is devoted, a group in the investigation of which ready access to the sea has afforded me special facilities. My object has been to work out as exhaustively as possible the general natural history of the Hydroida, and besides this to give a complete descriptive Zoology of the Gymnoblastic or Tubularian forms of this Order. The work is thus divided into two parts - the first devoted to the Morphology, Physiology, Distribution, and other general considerations bearing on the entire Order of the Hydroida; the second, to descriptions of all the known genera and species which compose one of its most important and interesting Sub-orders - that of the Gymnoblastea. A very large proportion of the observations here recorded are entirely original, while it has, moreover, been my aim, in giving an account of the observations of others, to take nothing for granted which it was possible for me to subject to personal verification. It will be seen that the amount of labour thus involved is far from slight. Indeed, it is only by constant and widely extended explorations of the coast, both within the tidal zone and in the deeper sea regions, followed up by laborious microscopic investigations, that results of any value are to be expected. The plates have all been drawn from nature by myself, and are from the living animal. The soft parts, which constitute the chief interest in these wonderful organisms, are thus represented as they show themselves while the animal is still beneath the waters of its native seas. This is all the more important in animals which, like the gymnoblastic hydroids, retain in their dried state not a single character of value, and which even in specimens preserved in spirits lose almost all their beauty and many of their important zoological characters.
