brought from the Solway and "West Coast. The pollutions and 

 continual dredgings in the Tyne in the present day effectually 

 bar its progress up our river, and I am not aware of any record

 lower reaches of comparatively still water of the Tweed and 

 Tees are more likely localities for this fish than any other of our 

 Northern streams. S. 



The Sharp-nosed Sturgeon, A. sturio, is occasionally taken 

 off Redcar and in the Tees, and the Broad-nosed Sturgeon, A. 

 latirostris, appears to be the variety peculiar to the Ouse, the 

 former not being taken in that river. — T. Meynell.
