“ Between tlie eye and tlie upper mandible is situated a fiesliy 
eubstancGj resembling that of the common cock, which hangs 
down at right angles with the beak ; it is of an orange colour, 
and is narrow in form, being one inch and a-half long, and half 
an inch wide at the base, whence it gradually tapers throughout 
its whole length to the tip. The spur on the shoulders is strong 
and sharp, and is nearly an inch in length. 
Habitat. River Quorra, West Africa. 
Presented by Captain W. Allen, R.N., to the Zoological 
Society of London, from which specimen it was described, and 
since figured in Fraser’s Zoologia typica.
