1292 A GLIMPSE OF THE POST-TERTIARY AVIFAUNA OF QUEENSLAND. 
abundance at a lower level of the drainage area, it may perhaps be 
legitimate to infer that the uprise which has taken place has 
not greatly disturbed the relativ^e iev'els of the Cond amine watershed. 
As with the mammals, so with the birds of this period, a con- 
siderable number of genera still extant had become established 
and specifically differentiated, but materials not dealt with in this 
notice tend to show that they were mingled with many others 
which have become extinct. 
Postscript. — Since the paragraph headed N yroca australis was 
wi-itten, the improbability of this species being represented by the 
fossil bone in question, has become more apparent to the write)'. 
Finding recent species, for example Platylca flavipes and regm, 
more nearly approaching identity in certain of their bones than 
<lo the fossil sjiecies and N. australis, he is now di.sposed to give 
difference of epoch its full weight. And .since in a fauna charac- 
terized by a majority of extinct genera, it is more likely than not 
tliat all the .species of genera reaching to the present time were 
distinct from tho.se that ai'e now, he concludes that a name, 
reclusa, appropriated to a second extinct Xyroca, wiW be justifiable.
