c. Erythrura trichroa papuana subsp. nov. 



Differs chiefly in its larger size. The beak is mach thicker than in the 

 allied forms, the wing iu one male from Arfak is fnlly 07 mm. long. The colour 

 is of a deep green. The bine on the head in the one male before us occupies 

 practically the entire crown of the head, while in forms a and b it does not reach 

 beyond the hinder margin of the eyelids in the middle of the crown. Salvadori, 

 Oni. Papuas. c Mol. II. p. 442, has already mentioned the large size of an 

 Arfak specimen, and the less intensely green colour of the Moluccan skins. 



tl. Erythrura trichroa woodfordi subsp. nov. 



Solomon Islands: iVola, on Guadalcanar. Sharpe (Cat. B. Biit. Mas. XIII. 

 p. 380) has remarked that the bine frontal band is narrower, and that they are 

 " otherwise identical with those from Ternate." They are indeed as yellowish 

 green as Ternate ones, and the bill is not as thick as in those from Arfak. The 

 wing of two females in the Tring Museum is 03—64 mm. long. This form is 

 certainly not our form c, bnt very near to form h, from which it seems merely 

 to difier in a narrower frontal band, and perhaps a somewhat longer wing.

Ann. and Mag. Xat. Hist. (5), I. p. 374 (l.s78) ; Wiglesworth No. 216 p. 42. 

 New Hebrides : Tauna, Erromango. Differs in its much smaller size from 

 forms a, b, c, d. In colouration it is like a ; wing 54 — 55 mm. 



Kr. trichroa was frequently found nesting on Ruk Island in March, May, 

 iiud June. The nests are large and very loose structures with a big opening on 

 the side, so that the eggs are easily seen in the nest. The nests are placed on 

 banana-trees and bushes. The eggs are three to five in number, of a glossless 

 white, and measure : 17 : 13, 17-6 : 13, 15o : 12, 16-3 : 12-2, 16 : 13-5, 16-8 : 12-3, 

 10"1:12-1, 161 : 13-5 mm., and so on. Nehrkorn, Kat. Eiersammlitng, gives 

 17 : 13 mm. 



0. Urodynamis taitiensis (Sparrm.) (Wiglesworth No. 47, p. 11). 



Ruk, 1. 7. Is90. Local name: " Nikiyap." Only this one specimen was 

 obtained. 



10. Ptilinopus ponapensis Finsch. (Wiglesworth No. 261, p. 50). 



Very common. Local name : " Ute-ute." " Colour of bill light apple-green ; 

 iris between cadmium yellow and chrome yellow (Ridgway PI. VI. figures 

 6 and 8) ; feet light chrome-yellow ; claws blackish slate." The sexes of the 

 adult bird are perfectly alike, only the female has the wing generally 2 or 

 3 mm. shorter. In the first plumage of the young bird the feathers of the 

 upper and underside, and especially those of the wing-coverts, are tipped with 

 yellow; head and neck uniform dark green. In the next stage the plumage 

 is like that of the adult bird, except that the crown is still green and the 

 hind-neck more greenish. 



I have not seen sufficient material from Ponape to say with certainty that
