free gonophore of a form of hydroid called Syncoryne. The 
simple structure of this Sarsia can be seen in the two cuts, the 
smaller of which represents the young, the larger the adult form 
of the same jelly-fish. They were found very abundant near 
Monterey and Santa Cruz, and several specimens were taken 
from the Santa Barbara Channel, where, however, they were not 
found as abundantly as in the former locality. The species is 
readily distinguished from the Atlantic representative by its 
greater size and by the color, while the proboscis is much shorter 
than that of Sarsia mirabilis, so abundant at times on the coast 
of New England.^ As is well known, the Anthomedusan and 
Leptomedusan groups of Hydromedusae are supposed to arise as 
buds from fixed hydroids, excepting perhaps the somewhat 
doubtful case of the Lizzia recorded from Scotland, of Claparede. 
In genera where we have young Medusae budding from Medusae 
among these groups, as in Lizzia, Sarsia, and others, it is not 
impossible that a direct development in which no fixed stage is 
found, direct development not unlike that of Cunina, may exist, 
but such a form of development has yet to be described. The 
genus Sarsia has a development of young by the budding of new 
individuals from the proboscis of the parent S. prolifcra, and from 
a fixed hydroid Syncoryne. 
The piles of the wharf at Santa Barbara are peopled by a 
beautiful pale pink hydroid, belonging 
to the genus Syncoryne, which may 
possibly be the hydroid of the Sarsia 
just described. These hydroids are 
found in clusters with a common basal 
connection, each head rising from a 
single stem as shown in the figure 
given here. On a single magnified 
Hydroids. head we detect the club-shaped ten- 
tacles and the ovate " buds," which are Medusae in all stages of
