others are longer, more slender and compressed, and have oblique, concave, 
pointed crowns. It is probable that Leuciscus aethiops 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; Ll. 45%; 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; Ll. 68-7072, 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; Ll. 60%. 
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,
