268 MANUAL OF PHILIPPINE BIRDS. 



"A female from Bongao. 'Iris light yellow ; bill greenish plumbeous ; 

 feet greenish yellow.' The specimen now sent appears to be not quite 

 adult, but it shows the distinctness of the species from Ninox phttippennix 

 in the barred upper surface. The upper breast is barred with white and 

 dark brown, and the flanks are white, with longitudinal pear-shaped 

 mesial streaks of pale rufous-brown. The tail has likewise ten dark 

 bands, much narrower than in N. philippensis, which has six broad band? 

 of dark brown." (Sharps.) 



229. NINOX MINDORENSIS Grant. 

 MINDORO HAWK OWL. 



Ninox mindorensis GRANT, Ibis (1896), 463; SHARPE, Hand-List (1899), 

 1, 291; MCGREGOR, Bull. Philippine Mus. (1904), 4, 17; MCGREGOR 

 and WORCESTER, Hand-List (1906), 47. 



Mindoro (Whitehead, McGregor, Porter). 



Adult. In color and color pattern very similar to Ninox spilonota but 

 very much smaller; it also resembles .V. spilocephala in size and pattern 

 of upper parts but differs from the latter in having the breast and abdomen 

 cross-barred instead of boldly striped. Both rufous and light phases occur 

 in this species. 



Male. Jris yellow; bill, cere, and legs greenish; nails dark brown. 

 Length, 225; wing, 167; tail, 88; culmen from base, 20; tarsus, 30. 



Female. Length, 220; wing, 158; tail, 78; culmen from base, 20; 

 tarsus, 23. 



"An adult female of this little Mindoro hawk owl was obtained in the 

 lowlands, and is nearly allied to N. spilocephala Tweeddale, from Min- 

 danao and Basilan, resembling that species in having the top of the head 

 and nape barred with buff. It may, however, be at once recognized by 

 having the whole of the under parts, including the belly and flanks, 

 tawny-buff, traversely barred with brown, while in the female of N. spilo- 

 cephala, though the breast is generally like that of the present species, 

 the belly and flanks are always white, with longitudinal reddish brown 

 shaft-stripes. Length, 203 ; wing, 152 ; tail, 76 ; tarsus, 28. 



"I have of course carefully compared this species with Bourns and 

 Worcester's description of N. spilonotus, specimens of which were obtained 

 in Mindoro, but the much smaller size of this bird serves to at once 

 distinguish it." (Grant.) 



230. NINOX PLATEN I Blasius. 

 PLATEN'S HAWK OWL. 



Xinox plateni BLASIUS (in litt), HARTLAUB, Abh. Nat. Ver. Bremen (1899), 

 16, 271; MCGREGOR and WORCESTER, Hand-List (1906), 47. 



Mindoro (Platen). 



Adult female. Above reddish brown, slightly shaded with olive; top
