FAUNA AND FLORA OF NORFOLK : ROTIFERA. 141 
Tuesday, 8th. Corner of Barton Broad and dykes and river 
on the way there. 
Wednesday, 9th. Sutton Broad Fish Pond, far North border 
and three little dykes close to the laboratory. 
Thursday, 10th. Barton Broad, N., S., E. and W. 
Tuesday, 15th. Sutton Staithe — Dyke on the way. The 
Marsh, The Pulk holes, and a few little dykes round laboratory. 
Wednesday, 16th. Hickling Broad, and a few dykes in 
that district. 
A few remarks on particular groups, genera, and species 
will perhaps be pardoned by members who have not studied 
these animals and may be of interest to those who have. 
To begin with the Rhizota, or fixed Rotifers. I was 
disappointed with these. None were abundant except 
Melicerta ringens. 
Only two species of floscules occurred, both in Hickling 
Broad, and one of them in a tiny hole cut in th ■ marsh close 
to the laboratory. 
The queen of Rotifers, Stephanoceros eichornii, occurred 
i sparingly in one spot, the Fish Pond in Sutton Broad. 
Conochylus volvox was common in two or three localities 
in Sutton Broad, but I entirely failed to distinguish its newly 
described congener unicornis. 
The best takes in this group were quite a fair number of 
Melicerta janus on the east side of Barton, three Megalot rocha 
alboflav icons in the Heater, several ( Ecistes umbella and 
intermedins east of Barton. 
Amongst the Bdelloida. or “ creepy, crawly ” (as a little 
friend called them) Rotifers I am rather at sea. I confess I can 
only distinguish about twenty of this group and only made 
certain of nine in this district. 
Turning to the illoricate free swimmers, two species of 
Asplanchna occurred: brightwellii common on the west of 
Barton, and priodonta scarce at the north end of Barton. 
That extraordinary assymetrical Elosa worrallii turned up 
in one of the small dykes. 
Five species of Synchceta occurred nearly everywhere, as 
also did the common Polyarth. playptera.
