Mr. Walter Rothschild on 
a, b. ? ad. Los Ynglases, Ajo. 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 Grebe, and 
I have never seen it take to the wing. 
When swimming, the tail is held upright and the body 
lies very low in the water, which almost closes over the 
shoulders.

X.— On recently described Paradiseidse, with Notes on 
some other new Species . By Walter Rothschild, Ph.D., 
M.B.O.U. 
(Plates Y. & VI.) 
Since the appearance in 1898 of my 6 ‘ Paradiseidee ” 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, which would thus leave fifteen new 
species and subspecies. 
This continual stream of new forms of Paradiseidce 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 te Paradiseidce ,) we knew the 
eggs of only sixteen Birds of Paradise, viz., Ptilonorhynehus 
violaceus (1889), PElurcedus melanotis maculosus (1895), 
PE. viridis (1889), Chlamydera maculata (1889), C. nuchalis 
orientalis (1897), C. cerviniventris (1895), Sericulus chryso- 
cephalus (1889), Ptilorhis paradisea paradisea (1897), P.p. 
victories (1890), P. magnified alberti (1897), Paradisea apoda 
apoda (1884), P. a. august(e-victoriw (1897), P. a. raggiana 
(1883), Manucodia atra atra (1897), M. a. altera (1897), 
and M. comrii (1893). 
The following is a list of species and subspecies of which 
we now know the eggs; those marked with an * are in the
