Family BUBONIDAE.^ 



STRIX BAWEANA, new species. 



Specific characters. — Resembling Strix orientalis seJoputo Horsfield, 

 from Java, but much smaller and paler throughout; white spots on 

 upper surface much reduced, more roundish, and less inclined to form 

 bars; dark brown bars on lower surface much narrower. 



Description. — Type, adult female. No. 181450, U.S.N.M.; Bawean 

 Island, Java Sea, November 27, 1907; Dr. W. L. Abbott. Upper 

 surface (in somewhat worn plumage) brown, between cinnamon 

 brown and tawny, in places becoming more ochraceous, everywhere 

 with roundish dots of dull white which on the nape and scapulars 

 incline to irregular bars, the longer scapulars broadly barred with 

 white and narrowly with clove brown and the brown of the upper sur- 

 face; tail sepia, shading basally and on the inner webs of the feathers 

 to cinnamon and cmnamon buff, barred with dull creamy white, 

 broadly on inner webs, narrowly and irregularly on outer webs; 

 primaries between clove brown and sepia, shading gradually on outer 

 webs to cinnamon buff at the base, more or less sparingly spotted or 

 barred on the outer vanes with creamy white, cream buff, and buff; 

 broadly on inner vanes with various shades of lighter brown, tawny, 

 ochraceous, and buff, the inner feathers tipped with whitish; secon- 

 daries and tertials sepia, broadly, but in places brokenly, barred with 

 dull brown (between buffy brown and olive brown), dull white, and 

 various shades of ochraceous, buff, and tawny, and tipped with dull 

 white; wing-coverts brown hke the back, the lesser series sparingly 

 spotted with whitish, the median and greater series on the outer 

 webs broadly barred with white and narrowly with clove brown, on the 

 inner webs broadly with buffy white, buff, and ochraceous; facial 

 disks dull cream buff, immarked; entire lower surface creamy white, 

 much tinged in places by the buffy clay color of the bases of the 

 feathers, which show through, particularly on the throat, where they 

 form a conspicuous throat patch; all the lower parts, except the 

 chin, conspicuously, and regularly though rather narrowly barred 

 with clove brown, most broadly on the throat; thighs and tarsi dull 

 white, much tinged in places with cinnamon buff, and narrowly barred 

 throughout with clove brown ; hning of wing mixed creamy white, buff, 

 and ochraceous, spotted and more or less barred with dark rufescent 



» The family name Bubonidae should be retained for the horned owls and their allies, notwithstanding 

 that the generic name Strii has been transferred to one of the genera of this group; for rather than to take the 

 oldest generic name in a. family as the basis for the family name, it is much better for various reasons to 

 adhere for the family designation to the type genus (i. e., the genus from which the family name was first 

 formed) whatever may subsequently become its generic name. This is a course parallel to that pursued in 

 the case of type species of genera; is much more logical; and will obviate much, in fact nearly all, of the 

 confiLsion arising from the transfer of family names from one group to another. In the present instance 

 Bubo is the type genus of the family Bubonidae.
