others are longer, more slender and compressed, and have oblique, concave, 

 pointed crowns. It is probable that Leuciscus aelhiops Basilewsky, 1855, 

 belongs to this genus. Giinther's use of that species as the type of his genus 

 Myloleucus, 1873, will not interfere, since the name Myloleucus had been applied 

 by Cope, 1871, to other species not congeneric. Myloleucus of Giinther, 1873, 

 was "characterized by extremely broad, molar-like pharyngeal teeth, in a 

 single series." 



SQUALIOBARBUS CURRICULUS (Richardson) Giinther. 



D. 10, A. 11, V. 9, P. 17; LI. 45f; Phar. teeth 5.3.2 | 2.3.4, compressed, 



pointed. 



Dorsal origin midway from snout to base of caudal. Origins of the ventrals 

 below the third ray of the dorsal. Anal origin midway from the axils of the 

 ventrals to the base of the caudal. A minute barbel at the angle of the mouth. 



Silvery; blackish on the bases of the scales of the flanks and the back, 

 forming longitudinal vittae; silver-white under the edge of the opercle to the 

 shoulders; fins dusky. 



Ichang. 



SQUALIOBARBUS ELONGATUS Kner. 



D. 12, A. 12, V. 10, P. 19; LI. 68-70^, 30 scales from head to dorsal. 



Mouth reaching to a vertical from the nostril, not to the anterior border 

 of the eye. No barbels. Preorbital bone very large, close to the eye the 

 nostrils and the mouth cleft; suborbitals narrow, elongate. Pharyngeal teeth 

 5.4.2 | 2.4.4, compressed and hooked. Peritoneum blackish, silvered. Origin 

 of the dorsal halfway from the end of the snout to the base of the caudal, very 

 little farther back than the origins of the ventrals. Scales lustrous silver; 

 back darker, olivaceous. A close ally of Squaliobarbus dahuricus Basilewsky 

 from Mongolia and Mantchuria but distinguished by fewer scales in the lateral 

 line and by the position of the dorsal, nearer the head. 



Ichang. 



XENOCYPRIS NITIDUS, sp. nov. 



D. 3 + 7, A. 3 + 9, V. 9, P. 18; LI. GO^ 9 . 



Body much compressed, not keeled below, depth, or length of head, about 

 two ninths of the length, without the caudal. Eye large, two sevenths of the 

 head, equal its distance from the end of the snout. Suborbital bones narrow,
