Oss. 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 
Linneus, that the stomach of Cyprinide “is continuous with a short in- 
testine.” The following five species have each two cirri.
