EXPLANATIONS OF PLATES V AND VL 



By ERNST HARTERT. 



Plate V, Fio, 1.— Sylvietta neumaimi Rothsch. 



Sylvietta neumanni Rothschild, Butt. B.O. Club, xxiii. p. 42, December 1908. 



rTNHIS peculiar bird is named in honour of Professor Oscar Neumann. In 

 -L structure it appears to bo a very typical Sylvietta, but its coloration is 

 quite singular. Six specimens, four marked (J, two $, were collected by RudoH 

 Graver in July, November, and December, at elevations of 1,900 and 2,000 m. 

 in the primeval forests north-west of Baraka and west of Lake Tanganj'ika- 

 The females are perfectly similar to the males, only a little smaller. 



Plate V, Eio. 2. — Pachycephala moroka R. & H. 



Pachycephala moroka Rothschild & Hartert, Noi'. Zool. 1903. p. 106. 



We described this species from a single luisexed specimen, obtained in 

 the Moroka district, in the Owen Stanley Mountains, British New Guinea, between 

 3,000 and 0,000 feet. We did not see another siiccimen until Albert S. Meek 

 obtained 3 males and 1 female at Owgarra, Angabunga River, in November 1904 

 and January 1905, at elevations between 6,000 and 8,000 feet. The sexes are 

 alike. Cf. Nov. Zool. 1907, p. 472. 



Plate V, Fig. 3. — Pachycephala tenebrosa Rothsch. 



Pachycephala tenebrosa Rothschild, Bidl. B.O. Cluh, xxix. p. 20. Novembe.- 1911 ; Rothschild & 

 Hartert, AW. Zool. 1913. p. 508 ; Ogilvie-Grant, Ibis, 1915, Jubilee Supplement, p. 95. 



Meek and Eichhorn collected 9 specimens of this very soft-feathered, some- 

 what aberrant Pachycephala on Mount Goliath, east of the central part of the 

 Snow Mountains, where the B.O.U. and Wollaston Expeditions collected. C. Boden 

 Kloss collected a pair on the Utakwa River, 5,500 feet, in February 1913. 



Plate VI, Fig. 1.— Melipotes ater Rothsch. & Hart. 



Mdipoles ater Rothschild & Hartert, Biill. B.O. Cltt'i, xxix. p. 13 (1911). 



All we know of this most remarkable species are 3 slcins collected by the 

 German missionary, C. Keysser, on tlie Rawlinson Mountains, north of the 

 Huon Gulf, about 1,500 m. high. Though only one was originally " sexed," 

 there can be no doubt that one is a male and the two other females. They agree 

 all three in colour, but the male is much larger than the two females. 



Plate VI, Fig. 2. — Dicaeum nigrilore Hart. 



Dicaeum nigrilore Hartert, Bull. B.O. Club, xv. p. S (October 1904). 



John Waterstradt collected not less than 14 specimens, about 3,000 feet 

 high, on Mount Apo, S. Mindanao, in October 1903. The bird must have been 

 fairly common, and it is pccuUar that Walter Goodfellow, Avho made larger 

 collections on the same mountain, did not come across it.
