186 FISHES. MALACOPTERYGIOUS. Gobio. 



Barbus, Merr. Pin. 189. Will Ich. 259 — Cyprinus oblongus, maxilla 

 superiore longiore, cerris quatuor, pinna ani ossiculorum septem, Art. 



Ich. Syn. 8 C. Barbus, Linn. Syst. i. 525. Penn. Brit. Zool. iii. 357- 



Don> Brit. Fishes, tab. xxix. Gregarious — In the English rivers. 

 Length from 2 to 3 feet. Body usually olive on the back, and silvery on 

 the belly. D. 11, P- 13, V. 11, A. 9, c. 22. The second or spinous ray of 

 the dorsal fin strongly serrated on both sides. Spawns in April. Flesh and 

 eggs supposed by some to be hurtful, an opinion which Bloch refuted from 

 experience. 



59. B. orfus. Rud. — Mouth without blard. Body deep. 



Rutilus ktior, Rudd, or Tinscale, Will. Ich. 252 — C. or. Linn. Syst. i. 

 530. Rud, Penn. Brit. Zool. iii. 363 — C. orfus, Bloch, Ich. tab. xcvi.— 

 In the English rivers. 

 Length from 12 to 16 inches. Body deep and thick. Head small. Irides 

 yellow. Scales large. Back olive ; sides and belly of a gold colour ; ventral, 

 anal, and caudal fins red. D. 10. (the first short, the second spinous, and 

 slightly serrated). P. 19. (the first large), V. 9. A. 13. Spawns in April— 

 This fish, according to Willoughby, is found in the lakes and rivers of York- 

 shire, Lincolnshire, and Oxfordshire. Pennant and Blocb, inconsiderately re- 

 fer this species, so well described by Willoughby, to the Ervthropthalmus of 

 Linnaeus, which is also the ervthropthalmus of our venerable ichthyologist. 

 The serrated spinous ray of the dorsal fin has induced me to place it here 

 along with the Barbel, from which, however, it seems to differ, generically, in 

 shape, and the absence of a beard. It may be termed, after Willoughby, 

 Rubellio fluviatilis. 



Gen. XXX. GOBIO. Gudgeon— Tail forked. Upper jaw 

 longest. 



60. G. Jluviatilis. Common Gudgeon. — A single beard at

 large black spots on the sides. D. 8, P. 14, V. 8, A. 11, C. 21. In winter, 

 the gudgeon congregates in deep pools or lakes. In summer, frequents shal- 

 lows. Flesh highly esteemed.
