YoT the sake of reference, a description of this species which 

 has been recently described from Lord Howe Island is here 

 appended. It will be found allied to but distinct from N. novce- 

 zealandice, and N. hoobook. 



Specimens of a small Ninox from Lord Howe Island diifer 

 considerably from either of the continental forms X. maculata or 

 N. hoohoolc, and also from iV. novce-zealandice^ to which latter it is 

 most closely allied ; this species, which 1 propose to distinguish 

 under the name of Ninox alharia, may be briefly described : — 

 The face, lores, forehead, chin, and upper part of the throat in 

 some specimens snow white ; the general colour of the plumage 

 rich fawn or rusty-brown, deeper in tint on the sides of the chest 

 and under surface and upper tail-coverts ; each feather of the 

 chest has two distinct roundish spots of white which elongate 

 transversely and form two detached bars on the breast, but become 

 confluent on the flanks, the feathers of the under tail -coverts are 

 white with a terminal bar and centre shaft spot of rufous-brown; 

 abdomen, legs, and thighs rufous-brown, paler on the outer parts; 

 no spots on the head or hind neck ; the mantle and interscapular 

 region without spots in some, but sparingly spotted with white
