I'lif very gitut difference in form between Demieijntta tinil the present genus n»uy be more cleurly 

 shown by the statement that while the bill niid win;,', as well as the jjiMieral bulk, are nearly the 

 same ill the two, Ikmieijrettu has the tarsus aljout 2.7") instead uf ti.HU inches lou},', the miilille toe

that the proportions are entirely different in the two forms. The bill of Demiegrettu is also very 

 nuich more obtuse than that of Dichromanassa. 



Ikmiegretta nova'-lwllumUw (Lath.) is of more slender build than the type-species, and is scarcely 

 strictly conj,'eneric ; but it is otherwise similar, especially in the character of the plumage. The 

 bill is more slender, approachiuj,' in form that of Hydranassa, but still different ; the legs are also 

 mure elongated, but are decidedly less so than in the genus under consideration.
