Mouth arched, jaws closely invested by the lips which may have lea- 

 thery lobes, but no inner fold or horny covering. Barbels four (Barbodes, 

 Bleeker): or two (Capoeta, Cuv. and Val.): or none (Puntius, 

 H. Buch.). Eyes without adipose lids. Pharyngeal teeth 5 or 4, 3 or 4', 2 

 or 3/2 or 3, 3 or 4, 4 or 5. Dorsal fin rather short, its last undivided 

 ray being either ossified and serrated or entire, or articulated and not 

 osseous ; it commences nearly opposite the root of the ventrals : anal 

 rather short, in some species its second ray ossified. Scales large, of 

 moderate or small size : anal scales not enlarged. Lateral line complete, 

 or incomplete, when the former continued to opposite the centre of the 

 base of the caudal fin. 



This most extensive genus has been subdivided by various 

 authors into numerous genera and sub-genera, but, passing gradually 

 one into another, they have in the majority of instances failed to be 

 permanently accepted. The three sub-genera of those with 4, 2, or 

 barbels is useful and apparently correct, for the occasional abnormal 

 absence of one or more of these appendages in fish which are so ex- 

 tensively kept in an artificial state in tanks, does not appear sufficient 

 reason why such natural subdivisions should be excluded from 

 ichthyological systems. It is likewise remarkable that nearly 

 all forming the sub-genus Barbodes, provided they are soberly 

 coloured, and either have or are deficient in the lateral blotch, 

 grow to a large size : the brilliant coloured ones are mostly 

 residents of mountain streams, or of rivers contiguous to hills and 

 they are generally small. Those of the sub-genus, Capoeta,
