What we know, at present, of the characters of continental and 

 archipelagic individuals would not justify us in separating them spe- 

 cifiually. Blyth's description of the barbels is more accurate than 

 that of Buchanan, and agrees with examples from Java or Sumatra.

We would here draw attention to a fish from Borneo, named 

 Aperioptus pictorius by Richardson, and figured in. the ' Zoology of 

 the Voyage of the Samarang,' Fish. pi. 10. fig. 4. Unfortunately 

 he specimens were lost, so that no description could be given of 

 them. The fish has the form of a Lepuloccphalvs, the dorsal being 

 placed far backwards, nearly opposite to the ventrals. But the 

 mouth is represented as transverse, curiously lobed, and without 

 barbels. 



APPENDIX TO CYPRIXID^. 



The fresh waters of tropical Africa are inhabited by a very sin- 

 gular fish, most probably the type of a distinct family, which I should 

 not hesitate to introduce into the system but for the circumstance tliat 

 I have only three examples of this minute form for examination,
