ON NEW-GUINEA BIRDS. 171 



birds and one birdsegg, which were welcome to our col- 

 lection. As above said all the specimens are collected in 

 the Arfak district; unfortunately they are however without 

 dates and they are unsexed. Yet I believe an enumeration 

 of the specimens may be of some importance, as are also 

 some particularities about them, told me by Mr. Jens.

An adult specimen. — The type-specimen of Casuarius 

 papuanus has no white at all at the head, according to 

 the description and the coloured plate by von Rosenberg. 

 It is however a female, the male only might have a white 

 head. The specimen we have purchased now, shows an in- 

 dication of a light head. As the colours have disappeared, 

 it is at present not to be said to which «subspecies" the 

 bird belongs. I, for me, I believe that it is very probable, 

 we have on the western peninsula only the Casuarius pa- 

 puanus; C. edwardsi and westermanni have not the rank 

 of species or subspecies, because they are most likely colour- 

 variations of sex and of age of the same species. 



Besides the type-specimen, an adult female, which is 

 collected near Andai, 20 March 1876, we have a second 

 adult specimen from Hattam , collected July 1874 and 

 purchased in 1876 from the late Woelders; this bird has
