Like the last, this is rather a large species. It was placed by 

 Reichenbach in his genus Megaloprepia ; but I cannot see that it 

 possesses any characters to separate it generically from the members 

 of the genus Ptilojms. 



Male. Chin and upper part of throat pure white. Moustache, 

 sides, lower part of throat, and a narrow band separating the neck from 

 the mantle pale grey. Top and sides of head and back of neck greenish 

 yellow. Breast and a line beneath the grey band on the neck rufous. 

 Lower part of breast, abdomen, and flanks yellowish green. Crissum 

 and under tail-coverts pale yellow ; the latter striped with dark green. 

 Upper parts and wings bright green, with the centre of scapulars 

 and smaller wing-coverts rosy purple. First primary slightly nar- 

 rowed at tip. Secondaries edged with light yellow. Tail dark green 

 above, beneath dark smoke-grey, with an apical greyish-white band. 

 Bill yellow ; feet red ; iris orange-yellow. Total length 9| inches, 

 wing 6|, tail 3f, culmen f. No difference in the sexes. 



Immature. Top of head green ; lores and cheeks greenish yellow. 

 Throat greyish white. Sides and back of neck grey ; breast dark 

 ochre. Rest of plumage like the male. (Spec, ex Dorey, New 

 Guinea, Voy. Astrolabe.)

Like Pt. perlatus, save that the tail has an apical greyish-white 

 band above and below. Barely distinguishable from Pt. perlatus. 



46. Ptilopus iogaster.
