Ibis olivacea of Dubus. 185 



splendida*. The specimen which I have examined is fully 

 adult. It has a naked frontal shield at the base of the culraen, 

 broad and rounded posteriorly, while this shield is narrow and 

 almost acute posteriorly in the specimen that I have of L. oli- 

 vacea from Prince's Island. The colours are as follows : — 

 Head, neck, and lower parts brown with a slight bronze lustre, 

 more evident on the sides and under tail-coverts ; the 

 ear-coverts are paler brown ; the long feathers of the nuchal 

 crest have a purple lustre, in some lights bluish or greenish ; 

 the back, scapularies, and inner remiges are bronze ; the 

 lower back and upper tail-coverts darker and more green ; 

 the smaller and median wing-coverts metallic bronze-green 

 with coppery reflexions ; the greater coverts of the second- 

 aries golden coppery, narrowly edged with purple on the 

 outer web, deep blue, nearly black, on the inner web ; the 

 primary-coverts, like the quills, black, with steel-blue gloss ; 

 the under wing-coverts black, glossed with dark green or 

 blue ; the tail dark bluish green : " bill red ; feet greenish 

 flesh-coloured j iris grey-brown" (B'dttikofer). Wing 

 330 mm.; tail 150; culmeu (without the frontal shield) 111 ; 

 tarsus 72. 



I add the full synonymy of Ibis olivacea Dubus, and a 

 complete description of the bird from Prince's Island.
