620 Messrs. H. C. Robinson and W. S. Laverock on 



appear to be representative forms of one another, should 

 occur in the same district. H. httriyora is generally con- 

 sidered to be a dry country form of H. orientalls. Both 

 species, however, have been recorded from Port Moresby, 

 and a third form, H. nova-gidncce Meyer, has been described 

 from German New Guinea.

 Two females. 



''Very shy and scarce: generally found in j airs in the 

 neighbourhood of the sea, but sometimes further up the 

 Endeavour River. Iris yellow ; feet bluish white ; bill 

 black" {Olive).

13. *HiER0GLAUX HUMEHALis (Hombr. & Jacq.). 

 Ninox humeralis Sharpe, t. c. p. 180. 



A single specimen, of which the label has unfortunately 

 been lost, agrees well with an example of this species from 

 New Guinea with which Ave have compared it. It has been 

 previously recorded as Australian by Mr. De Vis (Ann. Rep. 

 Brit. New Guinea, Append. EE, p. 99, 1891). 



14. tHiEROGLAUX CONNIVENS (Lath.). 



Ninox connivens Sharpe, t. c. p. 176. 



A single male from Mt. Sapphiri, Cairns. 



This specimen has the stripes on the flanks somewhat 

 more reddish-brown, and the coloration of the upper surface 

 rather paler than the typical form. 



In this it would appear to agree with the form separated 

 as Ninox peninsnlaris Saivad., which, however, is described as 

 being very considerably smaller than typical H. connivens.
