1 74 CYPRINID.*. 



a-c, d-r/. Adult and half-grown. River Isar. Presented by Prof. 

 L. Agassiz and Prof. v. Biebold. 



This species has seven branched rays in the dorsal fin, and five 

 in the anal. Kessler (Naturgesch. des Kijew'schen Lehrbezirks, 

 Heft vi. p. 30) mentions this fish from the river Dniester, near 

 Mohilcw, but says that it is distinguished from the western form in 

 having one branched ray more in the dorsal and anal. Dybowski 

 (Cypr. Livlands, p. 71) regards this as a specific difference, naming 

 the form from the Dniester Gobio kessleri. 



32. PSEUDOGOBIO* 



Pseudogobio, Bleeh. Atl. Ichtliyol. Ci/pr. p. 29. 

 Sarcocheilichthys, Bleck. Cypr. I'rodr. p. 426. 



Scales of moderate size ; lateral line present. Dorsal fin short, 

 without spine, with its anterior portion in advance of the ventrals ; 

 anal fin short. Mouth inferior, both jaws with more or less dilated 

 lips ; a small barbel at the angle of the mouth is sometimes absent. 

 Gill-rakcrs rudimentary ; pseudobranchise very small. Pharynge-'l 

 teeth 5 5, hooked at the end. 



China ; Japan ; 1 Oimosa. 



The ]3ropriety of separating this genus from Gohio might *be 

 (juestioned ; yet, according to Eleeker's system, it enters not only 

 another family, but a distinct section, Gohio being r_'ferred to the 

 Leueiscini, and Pseudogobio to the Paralabeonini. it is true it is 

 not verj^ evident, from the characters given, how these two sections 

 are at all distinct from each other. — The species may be referred 

 to two sections : —

1. Pseudogobio brevirostris. 



D. 10. A. 8. V. 8. L. hit. 38-39. L. transv. 5/5. 



The height of the body is one -sixth of the total length (without 



caudal), the length of the head one-fifth. 8iiout obtuse, with the 



upper profile arched, short, not much longer than the diameter of 



the eye, which is one- third of the length of the head. Mouth 



inferior, small; jaws with broad lips, the inferior being indistinctly 



three-lobed, the upper fimbriated, and terminating in a very short 



barbel at the angle of the mouth. Pra^orbital an isosceles triangle, 



with the point diiected forwards, united by a broad suture with the 



succeeding suborbital, which, like the following, is much broader 



than the fleshy portion of the cheek imderneath. The origin of the 



dorsal fin is much nearer to the end of the snout than to the root of 



the caudal ; ventrals inserted below the hinder half of the dorsal.
