vious augmentation of the trachea. As in the spoonbill also, in 
which the formation of the lower portion of the trachea is the

the muscles, and consequently it is found to produce few varia-

stork, heron, pelican, gannet, corvorant, or loon, has any such 
structure. Of thejabiru and albatross I cannot speak with any 
certainty.
