to the arrangement found in Sharpe's Handlist ' and the names used 

 are given in accordance with this hst in most cases. In a few instances 

 relating to North American birds, to avoid confusion with the system 

 of names found in the previous tables, the names given are those of 

 the A. O. U. Checklist for 1910 as in tables 3 and 4. Such deviations 

 from the general rule are indicated by reference to a suitable footnote. 

 This has eliminated confusion in generic names that might otherwise 

 arise, as for example in the case of the two closely related scaup ducks, 

 where the lesser scaup is given in table 3 as Marila affinis, while fol- 

 lowing Sharpe in table 5 the greater scaup would appear as Fuligula 

 marila. By using the name in the A. O. U. Checklist this is changed 

 to Marila marila thus dispelling any uncertainty as to the relation- 

 ship of the two birds in the minds of those not familiar with the 

 changes that have occurred in the application of generic names to 

 these birds.
