BATRACHOSTOMUS. 297 



about 30 mm. posterior to this with blackish tips but without the double 

 bars ; crissum buffy ; primaries and secondaries blackish, mixed with chest- 

 nut-rufous on outer webs; primary-coverts nearly totally black, each of 

 the secondary-coverts with a large white spot at tip, preceded by a smaller 

 black spot; axillars buff. A male from Basilan measures: Wing, 160; 

 tail, 121 ; culmen from base, 29 ; width of bill at gape, 41 ; tarsus, 16. 



Female. Similar to the male but colors less rufescent; white collar less 

 sharply defined and the light webs of scapulars washed with rufous. A 

 female from Basilan measures: Wing, 150; tail, 114; culmen from base, 

 27 ; width of bill at gape, 38 ; tarsus, 14. 



This species is easily distinguished from B. javensis by its larger size 

 and comparatively much shorter tail, and by the sexes being similar in 

 their general coloration.

"Adult male in very dark plumage. Crown brownish black marked 

 and mottled with buff, nuchal band of the same color; mantle and back 

 very similar to the crown, but with more buff finely intermixed ; scapulars 

 mostly clear buff, with mottled black barrings on the inner webs and a 

 black subterminal spot; wing-coverts black mottled with rufous, most of 

 the median and greater with a whitish spot at the extremity of the outer 

 web ; sides of head, chin, and throat finely mottled and barred with black 

 and buff, darker on the hinder cheek; bands above and below the chest 

 whitish, edged with black ; chest whitish buff, finely mottled with black ; 

 belly rather paler and more coarsely marked. 



"Adult female. General color uniform chestnut, with scarcely a trace 

 of any black markings except on the secondary quills; in other respects 

 very similar in plumage to the female of B. septimus. The outer webs 

 of the scapulars rufous-buff, each with a small subterminal black spot; 

 greater and median wing-coverts' with a terminal white spot on the outer 

 web, edged internally with black ; nuchal and pectoral bands white, edged 

 with black." (Grant.) 



Another male specimen was taken by Whitehead near Cape Engano, 

 northern Luzon. "It is an interesting specimen in the chestnut phase 

 of plumage, the upper parts being like those of the female type described 

 [above], but the outer webs of the scapulars are pale buff, as in the dark- 

 colored male type, though the subterminal black spots are small, as in 

 the female. The feathers of the throat and of the chest between the 

 white bands are paler chestnut than in the female, and have white
