detected another point of difference, the pale 
rosy colour of the spore contents, which was 
also noticeable after hatching at the posterior 
end of the swarm cell. She says, “ in 
Orcadella operculata the spores are practically 
colourless when seen in water preparation, 
while in the Norfolk specimen there is 
a distinct group of rosy granules often 
clustered about the nucleus. I think we 
may safely call the specimen an Orcadella. 
Orcadella operculata has been found so rarely 
and we know so little of the variations to 
which it may be subject, that for the present 
it would seem wisest to regard it as a form 
of that species — the first specimen hitherto 
found outside North America so far as 
I know.”
