This hydranth though immature in several respects, already 
exhibits the generic characters of that of Campanulina, being 
webbed at the base of the tentacles, which are surrounded by 
regular circles of nematocysts, and having a short conical hypo- 
stome. The hydrothecae of the adult hydroid only differ from 
those of more robust species of the genus in that each grows on a 
short stalk that arises directly from an adherent stolon while the 
gonothecae closely resemble those of C. repens, Allman, in outline. 
Major Lloyd! tells me that a short stem bearing a gonotheca as 
well as a hydranth is sometimes produced and that more than one 
medusa is often produced in a single gonotheca. 
If it is necessary to place the medusa as distinct from the 
hydroid in a recognized genus, greater difficulty is experienced. 
It agrees with Phortts, McCrady, and differs from Ezrene and 
Tima, Eschscholtz, in not possessing marginal cirri, but the ten-

tacles have a narrow longitudinal band of muscle on the velar sur- 
face and the gonads are less restricted in position than in most 
species of Phortis, though they do not until very fully ripe extend 
along the manubrial peduncle as in Tima. On the whole, there- 
fore. the medusa may be said to occupy a position intermediate 
between Tima and Phortis, but to be nearer the authentic species 
of the latter, to which it should probably be assigned, as Meyer’ 
suggests. 
The name Campanulina (1847) has priority over Phortis 
(1857) by ten years.

informed me as to the results of his observations, and shown me his preparations.
