WHITE SWAMP-HEN. 
In the original figure the spur on the wing is shown; no other figure shows 
this. In the skin in Vienna the right wing has a spur about 7’5 mm. and of 
a light horn-colour, the other wing has only a knob, but the spur has not been 
broken off. 
The figures quoted above have the middle toe and claw about equal to 
the tarsus. 
This brings us to a painting by George Paper, who drew this bird in 1790. 
No spur is shown on the wing, the tarsus is twice the length of the middle 
toe. It is a Porphyrio pure white ; legs, bill and shield red ; eyes dark brown. 
The drawing is said to be half natural size. This would make it a large bird, 
roughly as follows. Total length 640 mm. : wing 320 ; bill with shield 104; 
tarsus 186, middle toe 90, hind-toe 62. This description of Paper’s drawing 
can be called Porphyrio raperi sp. nov. 
As the type of albus differs from the type of the genus Porphyrio in having 
a large spur on the wing, I make the genus Kentrophorina for it, and it can 
be known as Kentrophorina alba (White). 
The oldest name for the Swamp-Hen is cyanophalus, which conies 
before calvus in the same page in 1819.
