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
