R. radjah. 
Medium-sized Anatine birds with long broad bills, long wings, medium tails, 
stout legs and feet. 
Anatine birds (strictly speaking) are characterised by their long bills, the 
length being always more than twice the depth of the bill at the base, 
short necks, and in having the metatarsus with a row of scutes on the 
front portion. 
The bill is about as long as the head, the culmen rather concave ; the 
nostrils are oval- apertures placed high up near base of culmen on each side 
of culmen ridge which is obscurely indicated ; naU rather broad and short ; 
the lateral edges of the culmen expanded anteriorly so that the bill is 
broader half way from the nostrils to the tip than at the base ; strong 
lamellas visible on inner edges of upper mandible for all their length. The 
under mandible narrow, the mandibular rami enclosing an unfeathered 
parallel-sided groove ; the nail small and flattened. 
The wings are long with the second primary longest, the third longer 
than the first, which is longer than the fourth. 
The tail is rounded and nearly half the length of the wing and more 
than twice the length of the culmen. 
The legs are long and stout ; the metatarsus has one row of scutes 
anteriorly placed, otherwise it is covered with reticulate scales ; it is longer 
than the culmen and more than half the length of the tail. The toes are 
long and fully webbed, the hind toe narrowly lobed. 
In the Catalogue of Buds in the British Museum, Vol. XXVII., p. 175, 
1895, the species I include in the genus Radjah is placed under the genus 
Tadorna, the type of which is the Common Sheldrake of Europe. The 
differences given between the genera Tadorna and Casarca in the Key, 
p. 142, read : 
‘‘ Edges of the bill with more or less prominent lamella. BiU broader 
towards the tip than at the base ; culmen rather concave ; lamellae
