BATRACHOSTOMIS. 297 



about 30 mm. posterior to this with blackisli tips but witliout the double 

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

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

 tlie secondary-coverts witli 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, 39 ; 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, 

 37; 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 pJuntage. — Crown brownish black marked 

 and mottled with l)uff, nuchal l)and of the same color; mantle and back 

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

 mostly clear l)uff, with mottled l)lack l)arrings 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

 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

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

 M'eb, edged internally with black ; nuchal and pectoral l)ands white, edged 

 with black."' (Grant.) 



Another male specimen was taken Ijy 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
