Measurements: All measurements were taken to the nearest half- 

 millimeter. The wing was pressed flat against the ruler. The "bill 

 index" is the sum of the culmen length and the greatest width of the 

 bUl. This index is an attempt to indicate the general "largeness" of 

 the bill rather than merely the customary length figure. Perhaps the 

 most obvious difference in dimension between large-billed and small- 

 billed birds is that of depth at the base, but no satisfactory comparable 

 measurements could be made of this because of the gTcat variation in 

 degree of bill closure effected by preparators. The plus sign (+) 

 indicates that the wing or tail was worn, and that the true measure- 

 ment would be perhaps a millimeter or so longer. Measurements of 

 excessively worn wings or tails were not taken.
