31. MUSCADIVORES NUCHALIS (Cabanis).

Carpophaga nuchalis CABANIS, Jour. fiir Orn. (1882), 126; SALVADORI, Cat. 
Birds Brit. Mus. (1893), 21, 190; GRANT, Ibis (1895), 116; WHITEHEAD,

Calayan (McGregor) ; Camiguin N. (McGregor); Fuga (Whitehead) ; Luzon 
(Whitehead) ; Mindoro (teste Hartert). 
This species has been established on the character of a cupreous chest- 
nut nape; otherwise it differs but slightly from MW. chalybura with which 
it appears to intergrade. Its status is somewhat doubtful.
