White-crowned Spur-wing. 
Vanellus albiceps , Gould, Proc. Zool. Soc. 1834, p. 45. 
Lobivanellus albiceps , Strickland, ibid. 1841, p. 33. 
The White-crowned Spur-wing has been placed by Mr. Strickland in his genus Lobivanellus, 
a genus the species of which possess four toes to the foot; but as the bird in question 
has only three toes, it should, I presume, be included among the members of his genus 
Sarciophorus, with which I have accordingly placed it. 
Two specimens, of this species, were procured at Fernando Po, by Captain William Allen, 
R.N., Corresponding Member, and presented by him to the Society. 
The crown of the head is white; the sides of the face and neck are grey; the back and 
scapulars are grey-brown, with purplish reflections; the rump and basal-half of the tail are 
white; the remainder of the tail is black; the shoulders, wing-coverts, and the first three 
primaries are black; the remaining portion of the wing, the chin, and the whole under surface 
of the body are white: between the eye and upper mandible, a fleshy lobe hangs down at 
right angles with the beak; it is of an orange colour, and of a narrow 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; the bill 
is yellow, with the exception of the tip, which is black; the legs are green. 
Total length, thirteen inches.
