in Shropshire, the Severn, the Teme, the Clnn, the Corve and the Onny. In 

 Merionethshire, the Dee and the Vyrmoz. In Herefordshire, the Arrow, the Lug, 

 the Dove, the Wye, and the Irwin contain them. In Hampshire and Wiltshire 

 in the Test, having been introduced from the Avon (Davy), also present in the 

 Itchen and both the Avons. 



The Swansea Guide states this fish to be taken in the neighbourhood, but this 

 Dillwyn doubts the correctness of. In 1863, 1470 fry were placed in the Lea 

 rather more than three miles beyond Hertford (Wix). In May, 1866, it was 

 introduced into the Lornan at Tiverton (Parfitt). It appears also to have been 

 introduced into the Thames. 



Ireland. — Rutty, 1772, observes " Thymallus, the Grayling or Umber. With 

 us it is a sea fish, and less than Willughby's, which is a river fish." It seems to 

 me probable that he may refer to Coregonus oxyrliynchus as I received the example 

 figured, as a grayling. Brown two years after Rutty (1774) enumerates the 

 grayling : but Thompson observes that " the parr has been sent to me from the 

 south of Ireland under the name of grayling. Perhaps this name, as applied to 

 the parr, may be a corruption of the word graveling, which is generally applied 

 to that fish in the southern counties." 



For the example figured, which is a male \h\ inches in length, I am 

 indebted to the Earl of Ducie, who captured it in the Test, April 30th, 1879. In 

 the club fishing waters in that river at Stockbridge and Houghton, a memorandum 

 of the largest grayling captured every year from 1834 to 1874 was kept ; it shows 

 the annual variation to be between 3j lb. to 31b. 11 oz. 



Pennant records one of 4 lb. 6 oz. from the Tame at Ludlow. Yarrell mentions 

 another one of 4<\ lb. from the Test, and Daniel one of 5 lb. from near Shrewsbury. 

 In Lapland it is said to reach to 8 or 9 lb. weight.
