Hadrostomus is intermediate in form between Tityra and Pachy- 

 rhamphus. The males are mostly black or cinereous, the females 

 very different, of various shades of brown. The genus has nearly 

 the same distribution on the American continent as Tityra, and is 

 besides represented by a peculiar species in the Antilles.
