81^ Birds of Celebes: Ardeidae. 



A. sumatrana was separated generically, as Typhon, by Reichenbach, but 

 there is no prominent peculiarity, so far as we can see, by whicli it may be 

 separated from the Common Heron, A. cinerea, the type of Ardea, to the young 

 of which it bears much resemblance in coloration. Its tarsus is covered with 

 hexagonal and pentagonal scales of irregular shape, and its middle toe is about 

 three-quarters the length of the tarsus, wherein, amongst other points, it differs 

 from the Purple Heron, Phoyx. 



GENUS NOTOPHOYX Sharpe. 



Herons of small-medium size, distinguishable from Ardea by the slender, 

 unserrated bill, from Herodias by their coloured plumage, the absence of decom- 

 posed dorsal plumes, from Demiegretta by their crest, relatively longer tarsus, 

 longer bare part of tibia (V3 the length of the tarsus), and longer tail. The 

 tarsus is transversely scaled anteriorly on the upper two-thirds, reticulated with 

 small scales behind.
