"Only immature specimens are in the collection, but these differ so 

 much from specimens of G. ahingdonl of the same ag'c that it is very 

 prol)able that adults will be found to differ correspondingly. Some 

 of the thickest-billed specimens are nearly indistinguishable from 

 small-billed specimens of G. conirostris prupiiuiaa of Tower Island. 

 Some arc close to G. hrevirostris.^''^

I have carefully examined Bermuda Cardinals and can not find that 

 they differ from mainland examples; nor should they, for the species 

 is said to have been introduced from the eastern United States.

]\fe)te concerning measurements. — All of the measurements in this 

 volume were originally made in inches and hundredths, but at the last 

 moment, after the manuscript had been completed, the author decided, 

 in view of the increasing use of the metric system among naturalists, 

 to have them converted into millimeters. This was accordingly done, 

 and the measurements as printed are the exact metric equivalents of 

 the original figures. For practical purposes the reader may of course 

 ignore fractions imder .5 of a millimeter.
