708 MANUAL OF PHILIPPINE BIRDS. 



"Guillemard thought his Cagayan Sulu specimens to be of the same 

 species with those from Sulu, though he mentions the lack of frontal 

 plumes in the former. Dn Sharpe has shown that the Sulu-Tawi Tawi 

 birds must be referred to C. borneensis, and if Guillemard was right 

 in believing the Cagayan Sulu birds to be identical with those from Sulu, 

 C. pectoralis must be excluded from the list of Philippine birds. 



"Five males from Sulu average: Length, 284; wing, 150; tail, 132; 

 culmen, 35 ; tarsus, 24; middle toe with claw, 26. Eight females, length, 

 273 ; wing, 149 ; tail, 123 ; culmen, 32.5 ; tarsus, 23 ; middle toe with claw, 

 24. Iris chocolate-brown to dark red; bill, legs, feet, and nails black. 

 Food insects." (Bourns and Worcester MS.)

 MENAGE'S DRONOO. 



Chibia menagei BOURNS and WORCESTER, Minnesota Acad. Nat. Sci. Occ. 

 Papers (1894), 1, 15; MCGREGOR and WORCESTER, Hand-List (1906), 

 107; MCGREGOR, Phil. Jour. Sci. (1906), 1, 775, pi. 4. 



Tablas (Bourns and Worcester, Celestino) . 



Adult. Very similar in colors to C. palawanensis, but distinguished 

 from that and all other Philippine species of the genus by the extremely 

 long and very deeply forked tail. A male in worn plumage measures: 

 Length, 355; wing, 141; tail (chord of longest feather), 187; bill from 

 nostril, 22.5; depth of bill at nostril, 11; tarsus, 25; difference in length 

 between the middle and outermost rectrices, 73 ; distance between tips of 

 outermost rectrices, 120. 



"Average measurements of nine males: Length, 336; culmen, 34.7; 

 wing, 137 ; tail, 175 ; tarsus, 25. Of seven females : Length, 327 ; cul- 

 men, 34.7; wing, 136; tail, 168; tarsus, 26. This curious species is by 

 far the largest representative of its genus yet discovered in the Philippine 

 Islands, and differs strikingly from both the other known species, one 

 of which is confined to Palawan and the Calamianes Islands, while the 

 other occurs in the Sulu Group and in Cagayan Sulu. C. menagei seems 

 to be strictly confined to the Island of Tablas where it is not rare in 

 the deep woods." (Bourns and Worcester.) 



"Iris very dark brown ; bill, legs, feet, and nails black. Food insects." 

 (Bourns and Worcester MS.) 



Genus BHUCHANGA Hodgson, 1836. 



Tail deeply forked and slightly shorter than wing; rectrices much 

 narrower than in either Dicrurus or Chibia, the outermost pair slightly 

 upturned at tips. Prevailing colors of plumage blue-gray and cinereous.
