FAUNA AND FLORA OF NORFOLK: ROTIFERA.

as far as Sutton is concerned; I account for this by the 
abundance of thriving weeds. Nuttall’s species ventripes, 
and our joint species Derbyi, both turned up. And here also 
I found three or four specimens of what I hoped Nuttall 
would agree was a species new to science, but unfortunately 
in pickling them and posting them to him, or in his 
search at the other end, they got lost. They occurred in the 
Marsh. 
Seven species of Euchlanis occurred in large quantities and 
in most localities, and five species of Pterodina including 
reflexa, incisa, and parva is not bad. 
The genus Brachionus was very remarkable by its scarcity. 
Only two specimens of Urceolaris occurred in the whole of 
Sutton Broad. 
Only two specimens of pain from East Barton. 
Only one specimen of urceolaris from West Barton. 
Only three specimens of bakcri from West Barton ; and 
very few angularis from South and West Barton, For these 
'usually abundant species this is a remarkable scarcity, and 
■was rather a treat than otherwise. 
Finally, five species of Notholca were scattered about in 
th • most unlikely places, including tiny dykes round the 
laboratory. 
I have drawn up a full complete list with localities, quantities 
.and dates, a shortened form of which is here printed. 
Through the kindness of another member of this Society 
I have had sent me a list of the Rotifers found in another 
part of the Broad District. 
That list contained about forty species. Why it is so small 
I can’d understand, perhaps the author confined his attention 
too much to the open river ; perhaps he was unaware of the 
bottle shaking process. 
I do not see why there should not be a very much larger 
list. There ought to be about 400 species at least. In my 
-six days I found 120 species, and am sure that if the wind 
and weather had been better my take would have been 
larger.
