“The ephyra stage of a Pelagid medusa which occurred 
in large numbers in our spawning ponds during the hatching 
season of 1910 reappeared this year, and its progressive stages 
were observed every time the ponds were skimmed for plaice- 
egos from the beginning of the hatching season until towards 
the end of April. As in 1910, efforts to rear these ephyre in 
order to identify the species were unsuccessful. The large 
and handsome Scyphomedusa, Pirlema octopus, usually 
common in this neighbourhood in March, was exceptionally 
abundant this year in May and June. 
“Repeated efforts have been made during the past few 
years to induce the local fishermen to bring in from the fishing 
grounds the sea-anemones brought up on their long lines. In 
this way several specimens of two or three of the rarer British 
species, such as Stomphia churchie, Aureliana augusta and 
Edwardsia carnea, have been obtained and recorded in previous 
Annual Reports. The commonest of these deeper water species 
is one the identity of which has long been in doubt, and we 
are indebted to Mr. T. A. Stephenson of Aberystwyth, to 
whom specimens were referred, for the following notes upon 
it:—‘I do not think there can be much, if any, doubt that 
it is what Gosse called Bolocera eques, though a different 
colour variety. The question is more—what is B. eques ? 
(1) It is certainly not a Bolocera. (2) As far as external charac- 
ters go it should be a Tealia, but not the same species as the 
ordinary shore Tealia. In that case it should be called 
Urticina eques, Gosse, as Tealia is really only a commonly 
used synonym of the earlier Urticina. (3) It may, however, 
turn out to be identical with a species described by Carlgren 
as Rhodactinia crassicornis ; if that is so, the name crassicornis, 
I think, has priority to eqgues: and the generic name would 
be Urticina, since there is no justification for generically 
separating Urticina and Rhodactinia. So, at present, I think
