THE BIRDS OF AUSTRALIA. 
cover specimens recorded by Rothschild and Hartert from German ( olim ) 
New Guinea, but, of course, series might easily show these to be separable. 
Probosciger aterrimus oorti subsp. nov. 
Type-locality : 
From Van Oort’s observations it is obvious that the birds inhabiting 
Dutch New Guinea need a name, as they are certainly smaller than the northern 
birds and as certainly larger than Australian birds with which Van Oort 
thought they might be united, but of the latter he had no specimens. He 
has given good measurements, so that I do not need to repeat them here, but 
his own figures show the differences well. This is the form Ogilvie-Grant 
was dealing with under the name Solenoglossus aterrimus goliath , but he did 
not differentiate between Northern and Southern birds, so that we have 
not his measurements of this form. Ramsay wrote about Port Moresby 
specimens, and there is one bird from that locality in the British Museum. 
It is quite possible that this may represent a different subspecies when 
more birds can be examined. From Rothschild and Hartert’s measurements 
these should be much larger than the present form and agree, if not exceed, 
in size, with the large Arfak birds.
