The blue collar is replaced by an indistinct collar of faint orange-yellow. Rump only slightly lighter than back and green, not yellow as in male. Under surface slightly lighter and more yellowish. Thighs green instead of yellow. "A young male is like the female but has less blue on sides of throat." (Bourns and Worcester.) "A male measures 168 in length; wing, 98; tail, 33; culmen, 18; tarsus, 12; middle toe with claw, 22. Two females measure: Length, 168; wing, 95; tail, 35; culmen, 19; tarsus, 12; middle toe with claw, 20. Iris dark brown; legs and feet light olive-green; nails black; bill blackish at tip, gray at base; cere black. Food guavas. All of the specimens obtained were shot from a flock found in a mangrove swamp the day before our departure from Samar." (Bourns and Worcester MS.) 248. BOLBOPSITTACUS MINDANENSIS (Steere).

Mindanao (Cuming, Everett, Steere Exp., Bourns & Worcester, Goodfellow, Celestino); Panaon (Everett). "Adult male.--Differs from that of B. lunulatus in having the cheeks green, the blue round the eyes separated by the green cheeks from the blue of the throat; the collar on the lower hind neck is of a brighter and deeper blue; the green of the head has a yellowish tinge, contrasting with the purer green color of the back. Iris dark brown; bill black, the base of the maxilla light gray; feet greenish." (Everett.) Length, about 152; wing, 96 to 99; tail, 33; bill, 18; tarsus, 10. "Adult female.--Exactly similar to the female of B. lunulatus." (Salvadori.) "Two males average, 159 in length; wing, 97; tail, 39; culmen, 18; tarsus, 12; middle toe with claw, 20. Six females, length, 154; wing, 96; tail, 41; culmen, 18; tarsus, 12; middle toe with claw, 19. Iris brown; legs and feet light olive-green. Called by the natives 'guayabero' from its habit of eating guavas. On the few occasions when we met with this species it occurred in flocks. It is a common cage bird in Mindanao. We searched in vain for it in Basilan, but are by no means satisfied that it does not exist there." (Bourns and Worcester MS.) Genus LORICULUS Blyth, 1849.
