Luzon (Whitehead). Formosa.
Adult.--This species is very similar to M. jagori from which it may
be distinguished by its smoky brown head and neck; fore part of crown
and sides of face blacker. The measurements of the type as given by
Sharpe and changed to millimeters are: Length, 96.5; culmen, 11.4;
wing, 48; tail, 35.5; tarsus, 15.
"Munia formosana Swinhoe, of which a specimen was recorded from
Isabela, north Luzon, appears to be a distinct pale-colored form,
the head, even in freshly-molted male examples, being of a dark smoky
brown. In addition to the specimens recorded in the Catalogue of Birds,
I have examined a number of Formosan examples of this species in the
Seebohm collection." Grant, Ibis (1896), 554.
