E. D. VAN OORT. BIRDS. 91 



so kind to compare the bird for me with one of SALVADORl's type-specimens, a female, in 

 the Tring Muséum, informed me, that notwithstanding the large size and the more rufous 

 tinge of the upper surface in our spécimen, he believes it to be the adult maie of S. arfakiana. 

 He states to hâve found the same différences in length of wing (6 — 8 mm.) in the form of 

 southeastern New Guinea. In the Leyden Muséum we hâve only one example, a female, 

 of S. arfakiana from N. W. New Guinea (Karon); this spécimen is at its upper and under 

 surface much more greenish than the spécimen from the Hellwig Mountains and is also con- 

 siderably smaller, wing 57, tail 42 mm. It seems to me very improbable, comparing thèse 

 two birds, that they should belong to the same form and I therefore describe hère the LORENTZ- 

 specimen as a new subspecies, named after Mr. J. W. VAN NOUHUYS, the travelling-com- 

 panion of Mr. LORENTZ.

N°. 360, çf, Alkmaar, 22 July 1907. Iris dark brown, bill and feet black. 

 N°. 415, Ç, Alkmaar, 25 August 1907. Iris dark brown, bill and feet black. 



The latter bird is sexed as female by Mr. LORENTZ; it is quite similar to the maie 

 spécimen.

General appearence and shape of the bill as that of Malurus alboscapulatus, but tail 

 longer and more rounded. cf. Above ashy brown, head and lores blackish brown; from the 

 base of the bill to above the eye a white stripe; upper tailcoverts buff; wings dark brown, 

 quills and wingcoverts edged with pale yellowish brown ; tailfeathers blackish brown, edged
