from base, 16: bill from nostril, 10; tarsus, 20. A female from Bohol, 
wing, 59; tail, 53; culmen from base, 15; bill from nostril, 9; tarsus, 19. 
“Common in Mindanao and Sggmar. Habits exactly like those of M. 
striaticeps. Four males average: Length, 144; wing, 60; tail, 56; culmen, 
16.5; tarsus, 18.5; middle toe with claw, 19. Four females, length, 135 ; 
wing, 55; tail, 54; culmen, 14.7; tarsus, 19; middle toe with claw, 18.5. 
[ris light yellow-white; legs, feet, and nails drab; bill nearly black, the 
lower mandible slightly hghter than upper. 
“Tt is remarkable that the differences between M. striaticeps and M. 
mindanensis should have escaped the notice of naturalists until they 
were pointed out by Doctor Steere. The two species are quite distinct, 
and can be distinguished with absolute certainty.” (Bourns and Wor- 
cester MS.) 
“Mr. Whitehead found a nest of this species [near Paranas, Samar, 
June 15, 1896] containing three eggs. These were in such an advanced 
stage of incubation that the young birds hatched out a few hours after 
the eggs were placed in his room. Eggs pure white, thickly speckled 
towards the larger end with dark red. The nest, a large ball of bamboo 
leaves and loosely constructed, was placed close to the ground in old 
forest.” (Grant and Whitehead.)

MOUNTAIN TIT BABBLER, 
Macronous mindanensis montanus MEARNS, Proc. Biol. Soc. Wash. (1905),

Macronus montanus McGRrecor and WorcESTER, Hand-List (1906), 82.

Lanao. 
Mindanao (Mearns). 
Adult male and female—Similar to Macronous mindanensis minda- 
nensis, but very much darker with heavier markings throughout; the 
dark shaft-streaks are increased in area and intensity; the blackish 
feathering of the upper side of the head occupies more of the nape; and 
the back and rump are prout’s brown instead of raw umber; the under 
parts are dark from the throat backward, the flanks being dark isabella 
instead of clay-color. This mountain form (from Pantar at 610 meters 
and Mount Apo at 1,220 meters) is slightly smaller than the subspecies 
mindanensis. It is still farther removed from Macronous striaticeps 
Sharpe from the Island of Basilan.” (MJearns.)
