Guimaras (Steere Exp.); Masbate (Steere Exp., Bourns & Worcester, McGregor); Negros (Steere Exp., Bourns & Worcester, Keay); Panay (Bourns & Worcester); Palawan (Steere, Whitehead, Platen, Steere Exp., Bourns & Worcester).
Adult.—Differs from T. javensis in having a wide band of light buff across the lower back thus resembling T. mindorensis from which it differs in having a much stouter bill and in having lower mandible gray or horn-white; lower mandible in dry skin dull yellow with a gray tip. In males the red malar-stripe is longer than in the other species mentioned and many of the black feathers of chin and sides of neck are tipped with red. Length of male, 420; wing, 220; tail, 180; culmen from base, 51; bill from nostril, 38; width of bill at base, 20; tarsus, 36. Wing of female, 218; tail, 185; culmen from base, 52; bill from nostril, 38; tarsus, 33.
The description and measurements above are from specimens taken in Masbate, one of the type localities of Thriponax philippinensis of Steere. In Catalogue of the Birds in the British Museum the type locality of Thriponax hargitti is given as Palawan. Of these two supposed species Grant says: “The types have been compared and agree in all particulars.” It seems to me almost incredible that this genus should be represented by the same species in Masbate and Palawan but as I have seen no specimens from the latter island I follow Grant’s identification.
“Iris yellow; legs, feet, and nails leaden; upper mandible black, lower horn-gray. Three males average, 430 in length; wing, 207; tail, 174; culmen, 50; tarsus, 48; middle toe with claw, 39. Three females, length, 410; wing, 204; tail, 169; culmen, 50; tarsus, 31; middle toe with claw, 39.” (Bourns and Worcester MS.)
