422 Dr. A. B. Meyer on Birds 



A male from Coiistantine Harbour or its neighbourhood 

 (Kubary). 



Easily distinguished from the three allied species — P. coro- 

 nulatus, Gr., P. trigeminus, Salv., and P. geminus, Sal\ r . — 

 by the grey cheeks and throat, the latter showing hardly a 

 hue of yellowish in its middle, as well as by the absence of 

 the purple stripe on the occiput in front of the yellow band. 

 The lilac of the head is much lighter than in P. coronulatus, 

 and more reddish than in P. geminus. (I have not specimens 

 of P. trigeminus for comparison as to this character.) Finally, 

 the yellowish brown of the belly is somewhat lighter, whereas 

 the yellow of the under tail-coverts and abdomen is more 

 intense. 



28. Ptilopus plumbeicollis, n. sp. 



Similis Pt. perlato et Pt. zonuro, sed capite cinereo ct collo 

 postico plumbeo di versus. 



Long. al. 0-155 m., caud. 0-076, rostri 0-021, tarsi 0-021. 



A specimen, not sexed, from Constantine Harbour or its 

 neighbourhood (Kubary) . 



Easily distinguished from Pt. perlatus and Pt. zonurus by 

 the whole of the head being light grey, only faintly tinged 

 with green on the nape and whitish towards the front, as also 

 by its sharply defined light plumbeous hind neck, which colour 

 stretches on to the sides of the neck. This plumbeous collar 

 is also possessed by the two other species, but in these it is 

 quite narrow, whereas in Pt. plumbeicollis it measures 20 mm. 

 in breadth. The brown of the breast is still lighter than in 

 Pt. perlatus. Pt. plumbeicollis has, like Pt. zonurus, a light 

 terminal band on the tail, but this is narrower (10 mm.) and 

 less vivid. The under tail-coverts equal those of Pt. zonurus. 



29. Megaloprepia poliura, Salvad. 



A specimen, not sexed, from Gumbu, N.E. New Guinea, 

 10th Nov. 1888 {Kubary). " Eyes dark orange-red, eye-ring 

 and lids tinged with citron-yellow; bill orange-yellow, base 

 of the upper bill purple up to the nostrils ; feet olive-green, 

 nails dark horn-grey." 



Length of the wings 0'160 m.
