122 SOME CHINESE VERTEBRATES. 
line descending little on the flank, ending on the middle of the tail. Form 
more slender than that of P. rivularis, as figured by Steindachner; back less 
high, dorsal lower; pectorals and ventrals much more produced; colors some- 
what similar, but having a lateral band of silver with faint darker cloudings. 
Lustrous silvery below the lateral lines; above the lines darker, blotched, 
and clouded faintly with brown. Fins, dorsal and caudal, with several oblique 
rows of small spots of darker brown parallel with the hind borders of the fins 
and not as in P. sinensis Kner.

D. 12, A. 8, V. 10, P. 15; Ll. 21533; total length 15 inches. 
Body compressed, depth nearly one seventh of the total length. Head 
compressed, little less than one fourth of the total, greatest width about two 
fifths of the length. Snout narrower than deep, high and broadly rounded at 
the end. Eye small, hardly one twelfth of the length of the head. Suborbital 
spine strong, rather slender pointed, not bifid. Barbels six; the maxillary 
applied to the side of the head reach the end of the snout. Mouth moderate, 
as wide as long; cleft subtruncate in front; upper jaws with a prominence on 
the symphysis. Cheek with small scales in front of the operculum backward 
from the mouth. Pectorals and ventrals with a membranous fold in the axils. 
Dorsal origin equidistant from eye and base of caudal. Ventral origins below 
the third ray of the dorsal. Anal origin halfway from the origins of the ventrals 
to the base of the caudal. Dorsal, pectorals, and anal slightly concave on the 
hind margin; ventrals little convex. Caudal deeply notched. Outer angles 
of all fins acute. Depth of caudal pedicel two fifths of its length. 
Brownish; head with narrow vermiculations and spots of bluish; each 
fin with about four oblique irregular and broken bands of brown; body with 
about six broad transverse bands of dark brown; the first and narrowest behind 
the gill opening, the second between pectorals and dorsal, the third on the 
origins of the ventrals, the fourth at the end of the dorsal base, the fifth above 
the anal, and the sixth, as long as deep, on the base of the caudal. 
The specimen described shows some variations from the type, though 
both were from the same locality.
