Obs. The Gudgeons thus defined are a very natural group, remarkable 

 for the extraordinary length of the abdominal canal. One of the only two 

 indicated by Cuvier from Buchanan's species, is an Opsarion, a genus no less 

 remarkable for the shortness of the abdominal canal than the Gudgeons 

 are for its length ; but as the distinctions on which the subdivisions of the 

 family are here made, have not before been observed, we cannot be surprised 

 that it should be repeated in the last edition of the Regne Animal from 

 Linnaius, that the stomach of Cyprinidce " is continuous with a short in- 

 testine." The following five species have each two cirri.
