CICONIID^—CICONIINyE: STOEKS. 653 



Just as we saw the American Spoonbill distinguished from Platalea of the Old World, so 

 does the American Wood Ibis differ from Old World Tantalus to a inarked degree in the 

 structure of the windpipe; but this time it is our bird which has that organ simple, it being 

 remarkably complicated in the other. In Tantalus ibis, typical of the genus, the trachea is 

 several times folded and doubled upon itself in the thorax. In Tantalus lociilator, the trachea 

 is short, straight, and simple in its lower part, with numerous reduced and modified rings, and 

 flattened from side to side, producing a ridge in front. It has been made type of a genus 

 Tantalides, but that name being preoccupied, a new one seems to be required.

' Mr. AUen informs me that the alleged New England case is doubtless erroneous (Bull. Xuttall Club, viii, 

 July, 1883, p. 187).
