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

 L. Agassiz and Prof. v. Siebold. 



This species has seven branched ra3's 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 

 Mohilew, 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 Qohio kessleri.

 Sarcoclieilichthys, Bleek. Cypr. Proclr. p. 426. 



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

 Avithout spine, with its anterior portion in advance of the ventrals ; 

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

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

 Gill-]'akers rudimentary ; pseudobranchise very small. Pharyngeal 

 teeth 5-5, hooked at the end.

The propriety of separating this genus from Oohio might be 

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

 another family, but a distinct section, Gohio being referred to the 

 Leuciscini, and Pseudogobio to the Pared ah eonini. It is true it is 

 not very evident, from the characters given, how these two sections 

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

 to two sections : —

D. 10. A. 8. V. 8. L. lat. 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. Snout 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. Praeorbital an isosceles triangle, 

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

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

 than the fleshy portion of the cheek underneath. 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.
