PATAGONIAN EXPEDITIONS: ZOOLOGY. 



Head : No feathering ; the bare head is decorated with a wattle and 

 there is a large caruncle extending from the latter part of the culmen to 

 the back of the head. The wattles vary much in color and appearance, 

 when the bird is in repose or when very active ; lavender to bluish pink 

 are the prevailing shades when the bird is quiet ; these colors are intensi- 

 fied and the pink and red shades become vivid when the bird is excited. 



Neck : The bare skin of the neck is crinkled and terminates abruptly in 

 the snow-white, downy ruff around the lower neck. There is a pendant 

 wattle immediately below this ruff, at the base of the neck where it joins 

 the chest. 



Back : Glossy dead black throughout, including rump and upper tail- 

 coverts. 



Tail : Glossy dead black. 



Wings : Scapulars and lesser wing-coverts like the back ; outer primaries 

 glossy black ; inner primaries and all the secondaries margined deeply on 

 all the exposed upper surfaces with ash-white, having a frosted appearance ; 

 the tips of the secondaries are glossy black, forming a terminal bar of that 

 color, when the wing is closed ; the wing as a whole has the shoulders 

 black and the rest of the wing ash-white, when closed ; when expanded, it 

 is black, white and black ; under wing-coverts and axillaries shining deep 

 black. 



Lower parts : Glossy dead black. 



Bill : "Brownish at the base, shading into clear white at terminal half 



and tip." (J. B. Hatcher.)
