Brown's \York, 'Canoe and (,!anip Life in British Guiana/ 

 p. 345 : — '"The white-headed inaroodie makes an extraordinary 

 rattling noise with its wings in early morning and late in th(i 

 eYening, evidently amusing itself or following a custom of its 

 kind, for when it likes it can fly noiselessly enough. I examined 

 their wings and found that the males have four curiously shaped 

 feathers at the tip of each wing with which they make this noise. 

 " The end portion of these feathers is stiff with very short 

 pennies. The white-headed females have only three of these 

 feathers in each wing, which are not so intensely modified as in 

 the male ; while the male of the common kind (^Penelope cridata) 

 has only two of these feathers in each wing, which are modified 

 in a less degree than those in the females of the white-headed 

 species." 



Family ODONTOPHORIDiE. 



The birds that compose this family are rather small, ranging in 

 size from the Common Partridge to that of the Quail, and are said 

 to represent the hazel-grouse of Europe. 



Tlieir distribution is South, Central, and North America. In 

 British Guiana two genera are represented by one species each.
