A, colony growing over Pasylhea quadridentata; B, gonosome from stolon growing over the same hydroid; C, stolon growing on the surface of gulfweed, with hydrothecae and gonangia. As indicated in my paper on " West Coast Hydroids, " I have felt that there was no proper place for the genus Hebella among the Calyptoblastic families that up to the present have been established. To this difficulty another was added, w'hen I came to the study of the Beaufort material, as I found a species that agreed with the genus Hebella in every respect except that the gonophores produced sporosacs instead of free medusae. This was not a new species, as it was described by Ritchie under the name, Cam(>anularia inutabilis " and by Warren, under the name Lafaia magna.b It can not belong to the genus Campanularia, as it has a tubular hydrotheca and a dome-shaped or conical proboscis, nor to the genus Lafa:a, as there is a diaphragm present in the hydrotheca and the gonangia are not collected into a Coppinia mass. In discussing the matter with Prof. Nutting I found that in his manuscript dealing with the Lafoea group, a portion of his Monograph of American Hydroids not yet published, he had instituted a new family, the Hebellidse, to include the genus Hebella, the absence of the Coppinia mass and the presence of a diaphragm at the base of the hydrotheca distinguishing it from the Lafoeidse and the conical proboscis separating it from the Campanularida;. This seemed a satisfactory solution to the difficulty, as it would not only supply a home for the genus Hebella, but would also include the other species to which reference has been made. To accommodate this species a new genus must be estab- « The Marine Fauna of Cape Verde Islands, 1907, p. 504. * Natal Hydroids, 1908, p. 342.. Please note that these images are extracted f
