* The British genera are distinguished by Italicks. Marks of doubt are 

 attached to some genera, with whose situation I am not perfectly satisfied, 

 either from not having had an opportunity of examining the type of the 

 genus, or from our ignorance of the habits or of the internal construction of 

 the birds referred to it. In most instances I shall refer to the cause of my 

 doubts as the genera occur.
