WHITE SPOONBILL. 



243 



lungs on each side is shown. In a young Spoonbill taken 

 from the nest, and examined by Willughby in reference to 

 this particular structure which is said to have been first 

 noticed by Aldrovandus, this peculiarity was not found ; and 

 as it has proved to be wanting in other immature examples 

 (c/. Zool. 1880, p. 514), it would appear that this formation 

 of the vocal organs (which is known to exist in old females 

 as well as in old males), is, like the occipital crest, obtained 

 by neither sex till they have acquired a certain degree of 

 maturity. 



The representation below is one-third less than the 

 natural size.
