 MEASUREMENTS OF THREE ALLIKD SPECIES OF Brachypttryx. 



Macronous mindanensis montanus subsp. nov. 



MOUNTAIN MACRONOUS. Tah-go'-saa or Tah-go-say'-ahn (Bagobo). Tar-man'-op 

 (Moros of Pantar and Lake Lanao). 



Type No. 192,312, IT. S. National Museum, from Mount Apo at Todaya 

 (4,000 feet altitude), Mindanao, P. I., July 12, 1904. Adult male. (Original 

 number, 13,728.) 



Adult male and female. Similar to Macronons mindanensis mindanensis 

 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 underparts are dark from 

 the throat backward, the flanks being dark isabella instead of clay color. 

 This mountain form (from Pantar at 2,000 feet and Mt. Apo at 4,000 feet) 

 is slightly smaller than the subspecies mindanensis. It is still farther re 

 moved from Macronous xtriaticeps Sharpe from the Island of Basilan. 



" Mac r 'onus mindanensis" was described by Steere from "Mindanao, 

 Samar, Leyte." As his party did not visit the mountains of the interior of 

 Mindanao it is safe to assume that the paler coa^t form was the one de 

 scribed. 



^thopyga boltoni sp. nov. 



MOUNT APO SUN-BIRD. Kah-poi-yah-poi'-yuh or Kah-pue-yoo-ahn' (Bagobo).

 Mindanao, P. I., June 25, 1904. Adult male. (Original number, 13,585.)

 middle of chin and throat, slate-gray, faintly washed with French green, 

 the feathers of the forehead narrowly edged with metallic French green ;
