known to Australian ornithologists. Tlic Watling (lra\yings 

 here come under consideration again, with the works of 

 Latham, Gmelin and the latter's translator, Kerr; while 

 the life-histories of the hirds are even more full and 

 interesting than usual. 



We maj' pass over the Osprey with its one "ill-defined'' 

 subspecies, which Mr. Mathews terms cristatus (Vieill.), the 

 variable Cerchneis cenchroides, of which no subspecies is now 

 admitted, and also Falco subniger which he puts under his 

 Notofalco, where a supposed Queensland subspecies is sup- 

 pressed. This takes us to the distinctly Australasian type 

 Hieracidea, placed next to Cerchneis; the author being very 

 emphatic as to the separation of both from Falco. Of this 

 Hawk innumerable variations seem to occur ; and, as thev 

 overlap in places, we sliould ourselves have refrained from 

 accepting, or giving, Latin appellations to each, while 

 considering them somewhat erratic manifestations of an 

 extremely variable species, or phases not yet sufficiently 

 fixed to warrant nonienclatural distinction. 



It is quite otherwise, however, with Spiloglaux nova- 

 zealandice, which may be next considered. Here the races 

 appear well-defined and capable of being geographically 

 separated, while some have been formerly distinguished as 

 species by Gould and other writers. We quite agree with 

 Mr. Mathews that the vast extent of Australia must always 

 be kept in mind ; and it will be noticed that in this case the 

 New Zealand bird is considered identical as a species with 

 the Australian, which therefore covers a still wider area. 



The subspecies of Hieracidea berigora admitted are 

 orientalis, berigora, occidentalis, melvillensis, kempi, centralis, 

 and tasmanica : the last three being new. Those of Spilo- 

 glaux are novae-zealandia, venatica, boobook, clelandi, leachi, 

 marmorata, albaria, royana, mixta, lurida, macgillivrayi, 

 everardi subsp. n., ocellata, and melvillensis. 



Hieracoglaux connivens may similarly be subdivided into 

 peninsularis, occidentalis, suboccidentalis, addenda, and con- 

 nivens, with ussimilis and rvfostrigata from the islands north 

 or east of Australia.
