tJ. S. p. R E. EXP. AND SURVEYS — ZOOLOGY — GENERAL REPORT. 



This genus has a much narrower and more depressed bill than Plilogonys. The feet are 

 similar, but with more curved claws, and with no feathers on the upper part of the tarsus. The 

 first quill is much larger ; indeed it can scarcely be called spurious ; the fourth, fifth, and sixth 

 are successively a little longer than the third ; the outer primaries not acuminate. The tail is 

 much broader, widening to the tip ; it is rounded, or graduated, instead of forked. The head has 

 a crest of narrow linear feathers, instead of a short, broad, and full one.
