gray ; above blue, washed with green, shafts black. A male from Palawan 
measures: Wing, 89; tail, 72; culmen from base, 21; bill from nostril, 
14.5; tarsus, 15. 
Female.—Scarcely differs in color from the male, but the moustachial 
streak dark purplish blue.. A female measures: Wing, 82; tail, 65; 
culmen from base, 22; tarsus, 17. 
“Common in Palawan and in the Calamianes, but difficult to see on 
account of its color. Found in the forests, second growth, and man- 
grove swamps. Seven males average: Length, 189; wing, 90; tail, 67; 
tarsus, 18; middle toe with claw, 17; culmen, 23. Four females, length, 
182; wing, 83; tail, 63; culmen, 23; tarsus, 19; middle toe with claw, 18. 
Iris brown; legs and feet slate-gray; bill black.” (Bourns and Wor-

Cebu (Hverett, Bourns € Worcester, McGregor) ; Mindanao (Platen, Celestino) . 
Male and female——Nearly the entire plumage leaf- or grass-green, 
much darker above than below; lores, ring about eye, ear-coverts, and 
chin washed with light yellow; outer webs of some primaries and inner 
webs of all the remiges and rectrices, edged with chamois-yellow; lower 
thighs chamois-yellow ; shafts of flight-feathers black. Three males from 
Cebu measure: Wing, 91 to 96; tail, 74 to 76; bill from nostril, 16 to 17. 
Three females, wing, 89 to 91; tail, 72 to 76; bill from nostril, 15 to 16. 
This species, which is very distinct from C. palawanensis, is rare in 
the only islands where it has been found. 
“Found only in the forest and breeding in June. Nine males average: 
Length, 200; wing, 92; tail, 75; culmen, 25; tarsus, 18; middle toe with 
claw, 20. Four females, length, 183; wing, 86; tail, 70; culmen, 24; 
tarsus, 17; middle toe with claw, 20. Iris dark brown to black; upper 
mandible almost black, lower drab.” (Bourns and Worcester MS.) 
Genus IRENA Horsfield, 1821. 
Nuchal hairs well developed, their exposed portions equal to about two- 
thirds the length of bill from nostril; nostrils hidden by short close-set 
feathers; a notch near the tip of each mandible; primaries longer than 
secondaries by much more than tarsus; tarsus less than bill from nostril; 
_ tail slightly rounded. Colors blue and black. In the thin and tender 
skin and hidden nostrils this genus shows some affinity to the Cam- 
pophagide; the well-developed nuchal hairs and short tarsus indicate a 
_ close relationship to the bulbuls.
