350 Mr. Walter Rothscliild on 



a, h. ? ad. Los Yuglases,, Aj6. Oct. 3, 1908. 



Irides dark brown ; bill dark olive-brown, lower mandible 

 marked with yellow ; legs and toes dark ash-coloured. 



Both specimens are moulting on the body and tail. 



This Duck is not commonly observed in the Ajo district, 

 where it frequents the open water surrounded by reeds. 

 On being alarmed it dives after the manner of a Grebcj and 

 I have never seen it take to tbe wing. 



When swimming, the tail is held upright and the body 

 lies very low in the water, which almost closes over the 



shouldei's.

 some other new Species. By Walter Rothschild, Ph.D.,

(Plates V. & VI.) 



Since the appearance in 1898 of my ^' Parudiseidte" in 

 ' Das Tierreich,' there have been described sixteen new 

 species and subspecies of Birds of Paradise ; of these one, in 

 my opinion, is a hybrid, wliich would thus leave fifteen new 

 species and subspecies. 



This continual stream of new forms of Paradiseidte shews 

 that we have very little final knowledge of the avifauna of 

 huge tracts of that wonderful island New Guinea. 



Before the publication of my '' Paradiseidce" we knew the 

 eggs of only sixteen Birds of Paradise, viz., Ptilonorlqiachus 

 violaceus (1889), ^'Elurccdiis ynelanotis macidosus (1895), 

 ^■E. viridis (1889), Chlamydera rnacidata (1889), C. nuchalis 

 orientalis (1897), C. cerviaiventris (1895), Sericulas chnjso- 

 cepludus (1889), Ptilorhis paradisea paradisea (1897), P.p. 

 victorice (1890), P.magjiificaalberti (1897), Paradisea apoda 

 apoda (1884), P. a. aurjustce-vicioricc (1897), P. a. raygiana 

 (1883), Manucodia atra atru (1897), M. a. altera (1897), 

 and M. comrii (1893). 



The following is a list of species and subspecies of which 

 Ave now know the eggs; those marked with an * are in the
