Dace is found in Europe noitli of the Pyrenees and Alps, and 

 ranges throughout Siheria ; it inhabits most rivers of England 

 and Wales, but is absent from Scotland and Ireland. Dace of 

 li lbs. have been recorded, but the specimen exhibited, 1 lb. 4 o/... 

 is exceptionally large ; it was taken from the Kennet at Kintbury 

 in September, 1916, and was presented ])y Frank Barker, Esq. 



46. Roach, Rutihis rutilus (fig. 20). — Although so similar to 

 the Chub and Dace in appearance, the Eoach is now placed in a 

 distinct genus because it has only one series of pharyngeal teeth 

 instead of two. It is usually deeper in form than the Dace ; the 

 rather large dorsal fin, of 3 simple and 9 to 11 branched rays, 

 originates above the end of the base of the pelvic fins. The Roach

is found in Europe north of the Pyrenees and x\lps, and in Russian 

 Turkestan and Siberia. In Britain it ranges north to Loch 

 Lomond and the Teith ; it is absent from Ireland. The record 

 English Roach, 3 lbs. lOi oz., was taken from the Bristol Water 

 Company's reservoir in November, 1904. The example exhibited, 

 a fine fish weighing 2 lbs. 8 oz., was taken in Hornsea Mere in 

 January, 1915, by the donor, E. Kempsey, Esq. 



47. Rudd, Scardinitis erytliropktiialmufi (fig. 21). — Biserial 

 pharyngeal teeth with pectinated edges characterize the genus 

 Scardinius. The Rudd is a deep-bodied fish, with a bronze or 

 golden tinge on the sides and with reddish fins ; the dorsal fin is 

 smaller and farther back than in the Roach, originating well 

 l)ehind the base of the pelvic fins. The Rudd occurs in Europe 

 (except the Iberian Peninsula), Asia Minoi-, Russian Turkestan
