Leuciscus hasak (Heck.) is not specifically distinct from L. aula, according

Squalioharhm curriculus (Rich.) has been described by Kner as JSarcochei-

Opsarius P elongatus, sp. n., Kner, 1. c. p. 368, taf. 15. fig. 1, from Shanghai. 
[This appears to be the type of a distinct genus, which the Recorder has named 
Ochetohius, see Fish. vii. p. 298.] 
Hypophthalmichthys nohilis has been described by Prof. Kner as H, mand- 
schuricus (Basil.) [the synonymy added being erroneus]. Novara, Fisch. 
p. 360.

[ Chanodichthys'] pekinemis (Basil.) and leucisculus (Basil.) are described by

Colter. Prof. Kner (/. c.) has described two species of this genus, viz. C. 
recurviceps (Rich.), under the name of C, erythropterus (Basil.), p. 360, 
* Prof. Kner^ who has taken Bleeker’s system as a guide in the determina- 
tion of Cyprinoids, has been several times very unfortunate in not referring the 
species to the proper genera. However, this is less his fault than that of the 
system followed, inasmuch as, by the principle of using the most insignifi- 
cant characters for the basis of genera and groups, the means of expressing na- 
tural affinities are destroyed, and determination becomes more or less impos- 
sible to one who has not a large series of types at his command.
