"A female from Bonj^ao. 'Iris light yellow ; bill gii'i'iiish pliimheous; 

 feet greenish yellow.' The specimen now sent ajjpears to he not quite 

 adult, but it shows the distinctness of the species from Nlnox philiitjjensis 

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

 dark brown, and the flanks are white, with longitudinal |)ear-shaped 

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

 bands, much narrower than in .V. pJiiiippensis, which has six broad bands 

 of dark brown." (Sharpe.)

Mindoro {Whitehead. Mcdregor. Porter ). 



Adult. — In color and color pattern very similar to \in(j.r spilonoia hut 

 very much smaller; it also resembles X. spilorrphala in size and i)attcrii 

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

 cross-barred instead of boldly stri[)ed. Both rufous ami light phases occur 

 in this species. 



Male. — Iris yellow; 1)111, cere, and legs greenish; nails dark brown. 

 Length, 225; wing, 167; tail, 88; culmen from base, 20; tarsus, 80. 



Female. — Length, 220; wing, 158; tail, 78; culmen I'l-om base. 2o ; 

 tarsus, 23. 



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

 lowlands, and is nearly allied to X. .^pilocephala 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 A. sipilo- 

 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, Td ; tarsus, 2«. 



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

 Worcester's description of A'. spiJonoiu.'<, specimens of which were obtained 

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

 distinguish it.'' (Grant.)
