Wright, must also be referred to the same species. Specimens 
sent me from the Frith of Forth by the latter gentleman are in- 
termediate in size between my Zubularia implexa and Coryne 
pelagica. The more humble growth appears to be not uncommon 
on our coast, as I have met with it several times on old crusted 
shells of Fusus antiquus, and Mr. Hodge has lately sent it me 
from Seaham Harbour, creeping over Cellularia pumicosa. As the 
curious and beautiful medusoid of this species has not yet been 
figured, I have given a representation of it in Pl. X., fig. 4.

Professor Allman established the genus Dicoryne for a zoophyte 
dredged in Orkney, in the summer of 1859, which proves to be 
identical with my Hudendrium confertum, a circumstance not at 
first recognised on account of the absence of reproductive capsules 
in the specimens I described from. Having since found several 
specimens at Cullercoats, with both male and female gonophores, 
the identity of the two supposed species has been placed beyond 
a doubt. I have, therefore, adopted Dr. Allman’s genus, though 
not without some misgivings as to the characters on which it is 
founded. The diversity of the reproductive organs is so remark- 
able, both in this family and in the Campanulariade, even where 
the genus is evidently natural—as in Coryne, for instance —that 
it seems impossible to found new genera on these organs alone, 
without having recourse to endless subdivisions. I am, there- 
fore, more inclined to take the character of the polypes as the 
basis of generic grouping in this family, allowing other charac- 
ters to modify this view according to their importance or perma- 
nency. ‘lhe form and position of the tentacles are of great im- 
portance in a generic point of view, and where these are simply
