 „ ,, Couch, Brit. Fish., Yol. 4, p. 22, pi. 183. 



Introduced in 18th century (1786) into Berwickshire. — Dr.

The Bleak is stated by Yorkshire naturalists as occurring 

 commonly in the lower waters of the Tees. — Clarke and Roebuck. 

 This is a very northern locality for this little fish, and as it bears 

 considerable resemblance to the Dace, it is very desirable to 

 examine some fresh Tees-caught specimens for verification and 

 confirmation. As the Bleak rises readily to the fly we hope 

 some enthusiastic Durham angler will soon be able to confirm 

 the existence of this southern and very locally-distributed fish 

 in the Tees. C. ? 



Fam. COBITID.E. Loaches. 



Nemachilus barbatulus (Willughby). Loach. 



Cobitis barbatula, Yarr., Brit. Fish., Yol. 1, p. 427. 



„ „ Couch, Brit. Fish., Yol. 4, p. 69, pi. 199, f. 2. 



In the Tweed and several of our burns. — Dr. G. Johnston. 

 In every stream near Stockton. — John Hogg. In the Ouseburn, 

 Dipton Burn, and most of the small burns in Northumberland 

 and Durham. It seems strange that Wallis has overlooked the 

 occurrence of this little fish, which is not rare even now in our 

 district. I have not heard of the existence of the Armed Loach 

 in these counties. R.
