Mearns A New Genus and Eleven New Philippine Birds. 3 



feet and claws sepia brown (from fresh specimen). Total length, 176 ; alar 

 expanse, 200 ; wing, 63 ; tail, 81 ; bill, measured from base of mandible, 14 ; 

 bill from nostril, 8.5 ; tarsus, 14 ; middle toe with claw, 23. 



Remarks. The type and only specimen of P. unicolor Hartert (Bull. 

 Brit. Orn. Club, Vol. XIV, No. cvi, p. 74, April 28, 1904) was taken by Mr. 

 John Waterstradt on a different part of Mount Apo, at an altitude of only 

 3,000 feet, or 3,200 feet lower than the type locality of P. griseipectux. Mr. 

 Waterstradt's specimen was killed in November while mine was taken in 

 July, and it is possible that his bird was an immature individual of the 

 species here described. 



Brachypteryx mindanensis sp. nov. 

 MOUNT APO SHORTWING. Boor-roo-wing' (Bagobo). 



Type No. 192,255, U. S. National Museum, from Mount Apo at 6,000 feet, 

 June 21,1 904. Adult female. 



The three Philippine species of Brachypteryx are closely related. In 

 color, the form from Mount Apo, Mindanao, is nearest to B. brunneic.eps 

 from the Island of Negros ; but the latter is the smallest of the three forms, 

 while the former is the largest. 



Adult male.. Similar to the male of B. brunnnceps, but larger and ap 

 parently less heavily washed with black on the top of the head and throat. 

 Belly without a trace of grayish wash present in B.poliogyna from the Island 

 of Luzon. Measurements of No. 192,256,11. S. National Museum, from Mount 

 Apo at 6,300 feet, July 4, 1904: Total length, 158 ; alar expanse, 220 ; wing, 

 70; tail, 62; bill from base of culmen, 14; bill from nostril, 9.5; tarsus, 33 ; 

 middle toe and claw, 23. Iris dark brown ; bill, feet, and claws gray- 

 black, darker than plumage. 



Adult female. Similar to the female of B. brunneiceps, but differs, in 

 addition to its larger size and relatively longer tail, in having the abdomen 

 washed with brownish gray. The wing-quills and spurious wing are 

 brown. Measurements of type: Total length, 158 ; alar expanse, 212; wing, 

 70; tail, 56 ; bill from base of culmen, 14; bill from nostril, 9; tarsus, 31 ; 

 middle toe with claw, 24. Iris dark brown ; bill, feet, and claws dark 

 gray. 



Young male in first plumage. Slate-colored feathers of the adult plum 

 age are present in the greater wing-coverts and pectoral region of the 

 specimen (No. 192,257, IT. S. National Museum, from Todaya, at 4,000 feet 

 on Mount Apo, July 11, 1904). General color clove brown, the feathers 

 slaty at base, all but the quills with russet shaft spots, which are small and 

 triangular on the back, and so extended as to give a general russet tone to 

 the abdomen. Iris brown ; bill and feet gray-black. Total length, 155 ; 

 alar expanse, 218 ; wing, 70 ; tail, 50 ; bill from base of culmen, 13 ; bill 

 from nostril, 8.6 ; tarsus, 33 ; middle toe with claw, 22. 



The name Boor-roo-wing', used by the native Bagobos, is in imitation 

 of the lisping notes of this bird, which suggest sounds of the winds.
