Show 1885.] DURING THE VOYAGE OF THE YACHT ' MARCHESA.' 271 and the colour shades more gradually into the brownish slate-colour of the back; the head, neck, and lower parts are also more brownish ; but the difference, as well as that of the nape, is certainly due, to a great extent at least, to soiling of the plumage. The wings &c. are a little bit darker and more brownish than in your specimen, and there is a more decided metallic bronzy purplish gloss, somewhat mixed with green, over the wings, but hardly perceptible on the back. The measurements are as follows:-Wing 23*0-25*4 centims.; culmen 2*1 centims.; tarsus 2*9 centims." Before visiting the Sulu Archipelago I had found this species in abundance on the island of Cagayan Sulu, off the north coast of Borneo, and Cassin's specimens were obtained from a small island near Balabac. Its area of distribution is thus somewhat curious, as it has never been recorded from Borneo. 53. MYRISTICIVORA BICOLOR (Scopoli). Myristicivora bicolor, Wald. Tr. Z.

Length of wing 21*6-22*4 centims. These examples have no black upon the tibials or under tail-coverts. In the female the external webs of the first two or three primaries have a white patch at their base, but this is not regular on either side. The same bird has the two internal secondaries wholly white. This species was extremely abundant in Sulu in the month of May, but it was most difficult to secure specimens, owing to the bird's habit of invariably keeping to the summit of the highest trees. 54.

Luzon (Gevers) ; Guimaras (Meyer) ; Negros and Basilan (Everett); Sulu (Burbidge). Mr. Sharpe says, loc. cit., speaking of a single specimen of this bird brought from Sulu Island by Mr. Burbidge, " I refer this pigeon with some hesitation to 1. griseigularis, of which I have never seen a specimen, and only know it from Mr. Keulemans' figure in 'The Ibis' for 1872. On the other hand, it is very closely allied to I. albigularis of the Moluccas, but differs in the greyish shade of the white throat, which is also more restricted, and in the forehead being grey with only a slight mark of lilac." 55.
