DUPETOR. 
Dupetor is the Asiatic species fiavicollis, while the species sturmi, the mono- 
type of Ardeiralla, is also noted under another genus-name. I am therefore 
making use of Dupetor for the species catalogued under that generic name in 
the Catalogue of the Birds in the British Museum, Vol. XXVT., and would point 
out that Ardeiralla is easily separated by means of its very short biU, in 
addition to other characters. The bill in Ardeiralla is exceeded by the 
metatarsus in length, while in Dupetor the biU is considerably longer than 
the metatarsr^.
