vi PREFACE TO THE SECOND EDITION. 



parent difficulty or "liitcli" is now met, for the diaguostic characters 

 of the difterent species are very obvious only in the adult males. A 

 careful consultation of the characters of the adult female and young 

 male following "cV' "cV' and "i^" in connection with the length 

 of the culmeu and the known locality, results, however, in the final 

 determination of the species as Platypsaris aglal^ (Lafr.). Rose- 

 throated Becakd. 



The measurements of eggs have been revised with the assistance 

 of Major Bendire, the corrections made being based upon the measure- 

 ment of a much larger number of specimens than were measured 

 before.
