1885.] DURING THE VOYAGE OF THE YACHT • MARCHESA.' 253 



Iris brown ; tarsus brownish yellow. Length 1 6*5-1 6*0 centims. ; 

 wing 9*4-9-6 centims. 



The five individuals of this species, all of which are males, are 

 almost identical both in colouring and measurement. The forehead 

 is bright orange-red, shading off into a rich orange on the nape. 

 Back and scapulars green, more or less washed with golden yellow ; 

 rump and upper tail-coverts light crimson, almost scarlet in some 

 lights, and with a silky gloss. The rest of the body-surface is green, 

 with the exception of a pectoral patch of the same colour as the 

 rump, which commences just below the chin. None show any trace 

 of blue on the head. 



This series, then, does not seem to differ appreciably from L. hart- 

 laubi, described by Lord Tweeddale, P. Z. S. 1877, p. 819 ; and a 

 comparison with the skins in the collection of the British Museum 

 shows merely a slightly more scarlet shade in the red of the Sulu 

 examples. But L. bonapartei of Souance also appears identical in 

 every way, and I have therefore adopted his title. In his descrip- 

 tion the beak is said to be black. It is worthy of note that in the 

 five Sulu examples under consideration the colour of the beak is 

 different in nearly every case. In two birds it is noted as "red," 

 while in the remaining three it is " brown black," " brownish," and 

 " very dark yellow." Yet no one bird appears more adult than 

 another. It is curious that in all the Sulu birds the beaks in the 

 dried skin are black.
