94 FAUNA OF NORTH WALES 



111. — BLEAK. Alburnus lucidus. Hech. & Kner. 

 Occurs in the Severn and lower Dee. 



112. — LOACH. Nemachilus barbatula. (L.). 

 Common, but only in the eastern half of the district. 



113.— SALMON. Salmo salar. L. 



Fairly common in the larger rivers and some lakes ; least numerous in 

 Anglesey and Montgomery. 



Sir C. R. Hoare, in a footnote to his translation of Giraldiis 

 Cambrensis' Itinerary, says that Giraldus was mistaken in his 

 assertion that Salmon do not penetrate into Bala Lake. 

 Pennant doubtless based his statement (quoted in the Fauna) 

 on Giraldus. Of Pont Aberglaslyn Pemiant writes {Tour, II., 

 362) ; " Above is a considerable cataract where the traveller 

 at times may have much amusement in observing the Salmon 

 in great numbers make their efforts to surmount the Wear 

 [Weir]. Near the place is a Salmon fishery. Here had been 

 a Wear in the time of Henry IV." Rev. W. Houghton in 

 Seaside Walks of a Naturalist, 38-47, gives an interesting account 

 of salmon-catching at Rhos Weir, the fish being retrieved by 

 a dog. On some of the Salmon he found the crustacean 

 parasite Lepiophtharies stromii. During the war the weir fell 

 into disrepair, and it is now (1919) useless. 



114.— COMMON TROUT. Salmo fario. L. 



Common and generally distributed in all suitable waters, and even in 

 apparently inaccessible mountain tarns. 



Mr. O. V. Aplin writes in the Zoologist, 1910, 107, the Trout in 

 the little river Daron are remarkable for the large size of the 

 red spots on their sides. A Trout weighing over 6 lbs. was caught 

 in Llanberis Lake in August, 1919. 



115.— SEA TROITT; SALMON-TROUT; SEWEN. 



Salmo trutta. L. & S. cambricus. Donov. 



Common in estuaries and rivers near the sea. 



Mr. R. W. Jones tells me that Sewen occur occasionally in the 

 stream at Aber ; while IVIr. G. Bolam states that Sea Trout 

 are found in Bala Lake and the streams entering it, having
