Cyprinid.®. 
Dr. Gunther has treated of this family in the seventh 
volume of his ^ Catalogue of Fishes.^ A revision of all the species 
known has convinced him that a great number of generic divi- 
sions proposed by preceding authors are based on characters 
which must appear trivial when the entire series is examined, 
and not a small portion only, like the Cyprinoids of a certain 
fauna. The arrangement proposed by him is the following : — 
First Group. Catostomina. 
1. Catostomus (Lesueur) with 29 species, 
2. Moxosioma (Agass.) with 5 species. 
3. SclerognatJms (Gthr.) with 11 species : Sclerognathus meridionalisy sp. n., 
from Central America (p. 23). 
4. Carpiodes (Agass.) with 1 species. ^ 
Second Group, Cyprinina. 
5. Cyprinus (auct.) with 3 species. 
6. Ca7'assius (Nilss.) with 3 species. 
7. Catla (C. & V.) with 1 species. 
8. Cm'hina (Cuv.) with 12 species : Cirrhina chinensisj sp. n., p. 36. . 
9. Jdangila (Gthr.) with 7 species. 
10. Osteochilus (Gthr.) with 17 species. 
11. 'Laheo (Cuv.) with 43 species, two being new, viz. Laheo hracTiypoma, 
from West Africa (p. 50), and Laheo mesops, from East Africa (p. 61). 
12. Barynotus (g. n.) with B. lagensis (sp. n.), from Logos (p. 61), and 
B. microlcpis (Blkr.). 
13. Tylog7\at1ms (G thr.) with 16 species, two being new, viz. T, striolatus, 
from Poona (p. 62), and T. elegans, from Mesopotamia (?) (p. 64). 
14. Abrosto7nus (Smith) with 4 species.
