Fish of the Tai-Hu. 
opening forward opposite hind pupil edge. Gill rakers about 1+7 short points, I of 
gill-filaments or i| in e5^e. Pseudobranchiae equal gill- filaments. Scales in even 
longitudinal series, all rather narrowly imbricated and largest on middle of sides ; 5 
to 23 irregularly waved radiating apical striae ; circuli moderate. Dorsal origin 
little nearer snout tip than caudal base ; first branched ray i to i^^ in head. Anal 
begins opposite last fourth of dorsal base or midway between pectoral and caudal 
bases; first branched ray if in head. Caudal well forked, little longer than head. 
Pectoral not quite reaching ventral ; i| to if in head. Ventral reaches anal, insert- 
ed trifle before dorsal origin ; i| to i| in head. 
Brownish generally. Lateral median vertebral leaden streak, darker on .sides 
of caudal peduncle. Dusky spot little less than eye about third and fourth scales 
of lateral line and another, smaller, on front of dorsal just below middle. Iris 
silvery white. Fins pale. Two examples, 57 and 58 mm. 
Rhodeus macidatus Fowler,' from the Pei Hoat Tren Tsin, is evidently the 
young. 
Acanthorhodeus asmussi (Dybowsksi). 
Head 2| to 4; depth 2 to 2i ; D. Ill, 12, i to 17, 11 ; A. II or III, 10, i to 
13, I ; scales 32 to 34 in lateral line to caudal base and 3 more on latter ; 6 scales 
above lateral line to dorsal and 5 below to anal ; 14 or 15 predorsal scales ; snout 3^ 
to 4 in head ; eye 2| to 3I ; maxillary 3^ to 4^ ; interorbital 2^ to 25. 
Body deeply ovoid, strongly compressed, deepest at dorsal origin. Caudal 
peduncle compressed, least depth i to if its length or i| to 2^ in head. 
Head width if to 2 in its length. Snout convex, in profile little less than eye ; 
length \ to I its width. Eye large, little less than interorbital, hind edge about 
midway in head length. Mouth small, inferior, lower jaw slighth^ included in upper 
gape short. Maxillary mostly concealed, reaches opposite hind nostril ; with 
short though distinct terminal barbel, at least in largest example. Jaw edges 
firmly trenchant. lyips thin, narrow. Nostrils together ; front one simple pore 
near last fourth in snout ; hind one greatly larger and exposed in crescent, at least 
3 times front one. Interorbital broadly convex ; preorbital little over half of e3^e ; 
first suborbital narrow, half width of second, which nearly covers cheek ; postor- 
bital narrow, like first suborbital. Opercle with few obsolete radiating striae. 
Gill-opening extends forward opposite preopercle ridge Gill rakers 1+7 short 
firm points, abovit \ length of gill-filaments. Pseudobranchiae f ot gill-filaments. 
Pharyngeal teeth 5-5, compressed, each with moderately narrow grinding surface 
and lower surface of each tooth with row of .short transverse blackish bars. 
Scales narrowly imbricated, in even longitudinal series, rows of slightly smaller 
ones along bases of dorsal and anal; 33 to 45 apical radiating striae ; circuli fine. 
Lateral line straight along side from upper angle of shoulder to middle of caudal 
base ; each tube simple an.d extends about over half of each scale exposure. 
Dorsal origin little nearer snout tip than caudal base, 2 front simple rays
