Tlie produce of the two ports during the ten years shows a grand 
total of 241, 99d lasts, consisting of 13,200 fish per last, or 
3,194,334,000 fish. A last of herrings is estimated to -weigh 
, 25 cwt., at which rate 302,494 tons of wholesome food have been 
landed at our two eastern ports during the penod named. The 
value of herrings fluctuates so greatly according to condition or 
supply that it is very difficult to estimate the average market price, 
but taking it at the very moderate estimate of TIO per last, it will 
be seen that this branch of the fisheries of the district has yielded 
an average return of £241,995 per annum. The years 1878, 1879, 
and 1880 have been less productive than usual, and have con- 
siderably reduced tlie average return, which taken for a like period 
to the end of 1877, showed an annual return of £25G,7G9.

ON THE OCCURRENCE OF 
SABINE’S GULL (XEMA SADINII) FOR THE FIRST 
TIME IN NORFOLK. 
By Hexry Stevenson, F.L.S. 
Read 28th February, 1882. 
The gunners and bird dealers in Yarmouth were much exercised 
last October (1881) by the appearance on Breydon,and its vicinity 
of two small Gulls with slightly forked tails which, when shot,* 
answered to no species with Avhich they were acquainted. One of 
* Others were said to have been seen, but if, as I was informed, some Little 
GnUs (Larue mvnutus) appeared at the same time, a doubt arises as to the 
identification of species.
