268 MANUAL OF PHILIPPINE BIRDS. 
“A female from Bongao. ‘Iris light yellow; bill greenish plumbeous ; 
feet greenish yellow.’ The speci now sent appears to be not quite 
adult, but it shows the distinctness of the species from Ninox philippensis 
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 bands 
of dark brown.” (Sharpe.) 
229. NINOX MINDORENSIS Grant. 
MINDORO HAWK OWL, 
Ninox mindorensis GRANT, Ibis (1896), 463; SHARPE, Hand-List (1899), 
1, 291; McGrereor, Bull. Philippine Mus. (1904), 4, 17; McGrrcor 
and WorcESTER, Hand-List (1906), 47. 
Mindoro (Whitehead, McGregor, Porter). 
Adult.—In color and color pattern very similar to Ninow 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.—tIris 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 NV. 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. 
“T have of course carefully compared this species with Bourns and 
Worcester’s description of NV. spilonotus, specimens of which were obtained 
in Mindoro, but the much smaller size of this bird serves to at once 
distinguish it.” (Grant.)
