Title
Robusta-Natalensis Pair. Sp. 30. C. Robusta. Sp.31. C. Natalensis.
Abstract
T he two giants of the genus-that is so far as the cock birds are concerned, but, as with chiniana and a few others, their hens are so much smaller that even when in the field the two sexes are seen in company one may often doubt their being a pair of the same species.
