24 BOURNS AND WORCESTER: PRELIMINARY NOTES. 



Central pair of tail-feathers shows faint traces of bars by reflected 

 light. Under surface pure white. Bend of wing white. Outer 

 tail-feathers, which are but half grown, tipped with white. Iris 

 very dark brown. Legs and feet almost white. Bill coal black. 



A young male, nearly adult, has a few white feathers on chin and 

 throat and a faint wash of light buff on the flanks. A much 

 younger bird has many of the feathers of the back tipped with 

 rusty brown and the greater wing coverts and quills washed with 

 the same color. Chin and throat almost pure white. An ill defined 

 black collar. The entire under surface washed with light buff, 

 deeper on the flanks. 



Adult male: Length, 6.87. Wing, 3.10. Tail, 2 80. Culmen, .76. 

 Tarsus, .86. 



Habitat: Masbate. 



This well marked species is extremely rare in Masbate. It feeds 

 in dense thickets in the deep woods and we never heard it utter a 

 note. The Luzon bird, C. luzoniensis, has a superciliary stripe but 

 this stripe is not nearly so broad as in this species and as the 

 strongly marked superciliary line is one of the most noticeable 

 characters of the Masbate bird we have named it accordingly.

Sexes alike. Feathers of the head and nape black, with heavy 

 rufous brown shaft lines. Feathers of back and upper wing coverts 

 bright reddish brown, with conspicuous nearly white shaft mark- 

 ings for their entire length. Tips of feathers black. The elon- 

 gated feathers of back which reach to tail- coverts with white shafts 

 and white shaft markings broad at base and narrowing at tip, edges 

 and extreme tips of feathers being dark rich fulvous brown. Upper 

 tail coverts rufous brown. Tail feathers fulvous brown edged with 

 rufous brown. Wing feathers rufous brown. Lores white. A su- 

 perciliary line of white extending as far as hind neck. Ear-coverts 

 fulvous with light shaft stripes, the latter becoming rufous on 

 hind-neck. A malar stripe of black. Chin and throat pure white. 

 Feathers of breast and abdomen have very broad white shaft 

 stripes, giving a streaked appearance to the under surface. Feathers 

 of flanks much elongated, light fulvous brown with distinct white 

 shaft stripes, broadest at base. Under tail-coverts colored like 

 flanks. Under surface of wing fulvous brown, brighter on coverts. 



Readily distinguished from P. basilanica by having all the feath- 

 ers of back, head, rump and upper wing-coverts with prominent 

 shaft lines, by the darker color of the long feathers of the back and
