MR. H. E. HURRELL ON THE POLYZOA IN NORFOLK WATERS. I97 
On November 26th I found some Cormorant skulls washed 
up ; probably the remains of birds gilled in the herring-nets. 
The Mackerel Fishery of 1910 (lasting from April to August) 
had 45 vessels employed, taking 278 lasts = i,78o,ooo fish; 
two boats less than in 1909, with an increase of 22 lasts. 
Gannets were reported as very numerous on the Herring 
grounds during the Autumnal fishing. 
The stranding of a Bottle-Head or Beaked Whale ( Hypero - 
odon rostratum ) at Hunstanton in December is worthy of note.

During the past few years it has been my endeavour to gain 
an acquaintance with the much neglected micro-fauna of the 
rivers, broads, ponds and ditches of Norfolk. Since taking 
up the study of pond life in general I have found in it such 
a vast field for work, if I may so term it, that I have found it 
necessary, as so many other naturalists have done, to stick 
to one or two departments of research only, my selections 
being the Rotifera and the Polyzoa. 
There is no richer storehouse of wonders to the naturalist 
than our ponds, ditches and rivers. Each search produces 
its special species, and the enthusiastic naturalist can always 
find something worth looking at and something worthy of 
his study. 
Personally I have found such beautiful things as Volvox 
globator, Floscularia ornata, and several beautiful species of
