1. D. maynifica (Peiiu.). N.W. Ncav Guinea {Sorong ; 



Salawati). 



2. D. seleiicides, Less. N.W. New Guinea (Arfak Mts.). 



3. D. chrysoptera, Gould {D. Jobiensis, Meyer) . 



4. D. septentrionalis, Meyer. Finisterre Mts. 



5. D. hunsteini, Meyer. Astrolabe Mts. 



The Arfak bird, of which he had recently seen upwards of' 

 one hundred examples, was an intermediate form between 

 the pale ochre-winged D. magnifica and the golden-winged 

 D. chrysoptera. D. septentrionalis was barely separable 

 from D. hunsteini, but had the deep crimson mantle-patch 

 of D. chrysoptera, while the birds from S.E. New Guinea 

 had the mantle-patch of a lighter crimson. D. hunsteini, 

 Meyer, with a richer golden-orange tint on the wings, was 

 believed by Dr. Sharpe to be merely a very old and brightly 

 coloured plumage of the ordinary Golden-winged Bird of 

 Paradise from the mountain-ranges of S.E. New Guinea. 

 The large series of skins of D. seleucides from the Arfak 

 Mountains showed tlie increasing richness in coloration of 

 these golden-winged species of Diphyllades, in proportion to 

 their age. 



Dr. Sharpe also pointed out that the species of Plover of 

 the genus Defilippia from Nyasa Land and the Zambesi 

 region was distinct from Defilippia crassirostris of Equatorial 

 Africa. He separated it as 



Defilippia burrowsii, sp. n. 

 Similis D. crassirostri, sed secundariis pure albis, et capitis 

 nigredine magis extenso, facile distinguenda. 

 Hab. in terra Nyasensi. 



Dr. Sharpe also made some remarks on the Grebes of 

 the genus Tachybaj)tes, and pointed out that four distinct 

 species had been confounded under the heading of T. minor. 

 Of these the African bird had received the " nomen nudum " 

 of Podiceps capensis from Bonaparte, which Dr. Sharpe pro- 

 posed to adopt.
