of nearly eight pounds weight. The other species or variety, 
which I believe to be nondescript, never exceeds one pound in 
weight. It is of a silvery hue and goes by the name of White 
Bream.” 
Since that time I have ascertained that this second species of 
Bream, which is very well known on the Continent, is very 
abundant in some parts of the river Cam, where it is called by the 
fishermen the Bream-flat — and from the Cam I have received and 
still possess specimens — As my M.S. is four months in advance of 
the publication of the Hist. Brit. Fish, to prevent if possible any 
chance of delay or disappointment my account of this fish is already 
written but not yet printed, or in type and will appear in the 7 th 
Part on the 1 st of Sep*" and I venture to presume that I am at 
liberty to make use of any part of the contents of your polite com- 
munication to improve my account — I shall give a figure of each 
of the Bream, and a scale also from the lateral line of two fishes of 
equal length to show the difference in size — those of the White 
Bream being the larger of the two, the eye is also larger — but the 
pectoral fin has three rays less, and the anal fin five rays less than 
in the Carp or yellow Bream — The names however are not wholly 
without objection — for both these Bream when young are white, 
and both equally flat. 
The fish called by Pennant the Shallow of the Cam is the same 
as your Rudd or Roud, a name, given by, or perhaps I ought rather 
to say that will be found in Willughby’s ‘Historia Piscium.’ The 
Germans call this fish Roth Oge,— it is the same also as the Finscale. 
This fish is not uncommon in Lincolnshire and Yorkshire in 
Scotland and in Ireland, in which latter country it is called a 
Roach. You will find by and by some notice of your FTorfolk 
Broads — Heigham Sounds and Horsey Mere, when I come to the 
Rudd and the Pike, and again thanking you for a new locality for 
and further information of this second species of true Bream I am
