514. MIXORNIS CAGAYANENSIS (Uiilleniard. 



CAGAYAN SULU TIT BABBLER. 



Mixornis cagayanensis Guillemard, Pioc. Zool. Soc. (1885), 419, pi. 25; 

 Sharpe, Hand-List (1903), 4, 53: McGregor and Worcester, Hand- 

 List (1906), 82. 



Cagayan Siilu {Guillemard) . 



Male. — "Above grayish olive; the forehead grayish, witli black shafts 

 to the feathers, the occipital region with a tinge of ehesnut; feathers 

 round the eye and in the parotic re^on ashy ; throat and chin pure white, 

 broadly striped with black; breast pale yellow, also broadly striped, 

 shading oft' below into the yellowish olive-gray of the crissuin and under 

 tail-coverts ; thighs with a slight reddish tint ; under wing-coverts white ; 

 wings chestnut; tail brown with traces of dark barring. Iris pale 

 yellow; bill and feet lead-colored. Length, about 145; wing, 64; tail. 

 60 ; bill from gape, 18 ; tarsus, 20. 



"This species, which was common in low bushes in the more open 

 situations in the island, is at once distinguishable from M. hornends by 

 the upper surface being of an ashy olive-brown instead of chestnut. It 

 has a loud note of alarm, is very restless in its movements, and apparently 

 rarely flies far off the ground." (Guillemard.) 



Genus MACKONOUS Jardine and Selby, 1835. 



Rictal bristles about as long as bill from nostril ; nasal opening oval 

 and not protected by a flap ; culmen from base less than tarsus ; long 

 feathers of the back reaching to or beyond the tips of tail-coverts, their 

 shafts stiff and usually white; feathers on sides of body long, decomposed, 

 and hair-like; most of the plumage loose and decomposed. Macronon^ 

 resembles Mixornis in its long dorsal feathers, but differs from the latter 

 in having the shafts of these feathers thick and stiff. Z ofiterornis differs 

 from both of these genera in having shorter dorsal plumes and in having 

 a flap above the nasal opening.
