Lonchura tristissima tristissima (Wallace) The adult is 105—110 mm long, the wing 52—55 mm, and the culmen 10—11 mm. It is burnt umber above, from forehead to lower back, wings and tail. There are whitish lines on the feather shafts on forehead, crown, superciliaries, lores and ear-coverts. There are faint streaks on the mantle and scapulars. There are whitish terminal spots on the median and greater wing-coverts, and pairs of sub-terminal spots on the tertiaries. In most of the birds that I examined in the AMNH, the edges of the median and greater wing-coverts were broadly marked with Mars brown (Smithe 223A). The rump is mainly brown, with a narrow bar of black immediately adjoining the uppertail-coverts. The short uppertail-coverts are straw yellow, the long uppertail-coverts are black. The tail is fuscous. From chin to belly and flanks it is sepia, which becomes black on the thighs, ventral region and undertail-coverts. The underwing-coverts are creamy salmon. The bill is steel blue or violaceous grey. The irides are dark brown. The legs and feet are grey. Lonchura tristissima hypomelaena (Sresemann & Paludan) The adult has the face blackish, the rest of the head and upperparts are hair brown. The lower rump forms a broad black bar. The short uppertail-coverts are bright straw yellow. Below, it is much darker than L. t. tristissima, tending to dark greyish-brown becoming black. Males are blacker below than females. Pallid streaks on the sides of the upper breast are more noticeable in the female, and may form a slight barring pattern (Rand & Gilliard 1967). The edges of the median and greater wing-coverts are black, forming two dark bars. There may be pairs of pale sub-terminal spots on the tertiaries, which also have dark edges. Lonchura tristissima calaminoros (Reichenow) This race differs by having the
