202 MR. H. E. HURRELL ON THE POLYZOA IN NORFOLK WATERS. 
I have had it reported to me from Wroxham, have taken it 
at Brundall. and in all parts of the river adjacent. 
It is often abundant on Surlingham Broad on Hornwort 
and Lily leaves ; is massed in the quiet and dark corners of 
the main opening in the Rockland Broad delta ; not abundant, 
but pretty constant in the slightly brackish waters of the 
Thurne and the Bure in the vicinity of Womack Broad and 
Potter Heigham ; is to be occasionally met with in the 
Heigham Sounds, Ormesby and Filby Broads, Stalham 
Dyke and Barton Broad, and there was statoblastic evidence 
of it at the end of the summer in Mr. Robert Gurney’s beautiful 
piece of water known as Calthorpe Broad. 
Plumatella fruticosa is a beautiful variation of the genus, 
and I have come across it in Surlingham Broad as well as the 
somewhat rare species Plumatella punctata , of both of which 
I have specimens. Some years since I came across a species 
that I thought was new; but Dr. Harmer hesitates to recognise 
it as such, although it is admittedly a variation of P. repens 
and closely allied to P. fungosa. This is not actually a Norfolk 
species, having been found in an old pond at Carlton Colville 
near Oulton Broad. It is a grand polyzoon when living, and 
its tentacular crown of greater delicacy and length than in 
any of the other species. 
One year the tentacles on the lower half of the lophophore 
flickered in all the animals taken with such regularity that 
I took it to be a habit of the animal, but in this year’s collection 
the flickering motion was scarcely observable. I am hoping 
to get this species either identified or adopted as a new species 
by the expert polyzooist at the Calcutta Natural History 
Museum, who has some of my specimens for examination. 
Another interesting species is Plumatella fungosa, which 
I have found in a brackish ditch within a stone’s throw of 
my own house in Yarmouth, and more abundantly at South 
Walsham, where it had seized upon the submerged twigs and 
branches of trees growing by the water side. This is a pro- 
lific species, and when taken towards the end of J une threw 
out a species of spindle-shaped larvae in large numbers. 
The tubes were also well filled with statoblasts.
