some Eastern Owls. 171 



several sexed examples of this form collected at Tonglioo, 

 from which I have noted the following measurements, that 

 may perhaps be worth recording : — 



Wing. Tarsus. 



Male 8-80 I'lO 



do 8-60 1-20 



1 8-50 1-10 



Five females i to to 



1 8-9o 1-20 



An unsexed specimen in the same collection from Assam, 

 apparently referable to the same race, has a wing-measure- 

 ment of 9'10, with the tarsus 1'20. 



One of the scarcer species of Ninox in Captain Wardlaw 

 Ramsay's collection is N. obscura, a native of the Andaman 

 Islands, which bears a curious similarity in the nearly 

 uniform fuscous coloration of its underparts to the more 

 southern N. theomacha, from which, however, it is readily 

 distinguishable by its larger size and darker abdomen, as 

 well as by the tail (which is only partially cross-barred in 

 N. theomacha) having from four to five dark transverse bars, 

 and also bearing a white tip. 



I have taken the following measurements from Captain 

 Wardlaw Eamsay's three specimens of N. obscura, which, if 

 correctly sexed, exhibit the curious peculiarity of the male 

 bird being longer in the wing than the two females ; I may 

 add that one of the latter has several snow-white feathers 

 on the nape, which bear the aj)pearance of an accidental 



variation ; —
