THAYER AND BANGS: AVES. 157 
The differences in color that were at one time (see Ogilvie-Grant, Ibis, 
1900, ser. 7, 6, p. 600) thought to distinguish P. derbyana Fraser from P. sal- 
vadorvi Oustalet are sexual, males have bright red upper mandibles, no brownish 
mark across the neck, and lavender-blue underparts; females have black 
upper mandibles, a brownish purple marking crossing the side of the neck, and 
lavender-lilac underparts. 
Young males have red bills, the inner edges of their primaries are yellow- 
ish green, their tails are short and their underparts, crowns, and under wing- 
coverts are mostly green. 
Rothschild (Bull. B. O. C., 1899, 8, p. lvi) considers it best until the 
original locality of P. derbyana is known to recognize P. salvadorwi as a sub- 
species on account of its apparently smaller size. Our two adult males have 
the wing 216 and 218 mm. and the two adult females, 210 and 213 mm.
