Recently published Ornithological Works. 193 



give a list of the races in subsequent parts. In other respects 

 Mr. Dresser appears to have carried out his difficult task 

 admirably, though we may suggest that Montagu's Harrier 

 and the Hen Harrier by no means always fly low, and that 

 they are often distinctly vociferous at the nest. 



The eggs figured in this Part are those of Elanus cceruleus, 

 Circus asruginosus, C. cineraceus, C. swainsoni, C. cyaneus, 

 Biileo vulgaris, B. zimmer manna, B.ferox, Archibuteo lagopus, 

 Pernis apivorus. 13 species of Sylvia, and 2 species of 

 Metizophilus. 



7. ' The Emu.' 



[The Emu. A Quarterly Magazine to popularize the Study and 

 Protection of Native Birds. Official Organ of the Australasian Ornitho- 

 logists' Union. Vol. v. pt. 2 (Oct. 190-5) and Supplement. Melbourne, 

 1905.] 



' The Emu' for October, 1905, contains an important 

 article on one of the Lyre-birds (Menura victories) by Mr. A. 

 E. Kitson. The habits are fully described, the nest and 

 eggs are figured, and the bird's capacity for mimicry is 

 noted, an important fact (apparently unknown hitherto) 

 being that the female is almost as clever a mimic as the 

 male. Mr. F. L. Berney continues his " Field-Notes on 

 Birds of the Richmond District, North Queensland," while 

 various other articles and notes complete the Part. 



A supplement contains " A Dichotomous Key to the Birds 

 of Australia," by Mr. A. G. Campbell, who hopes that it 

 will be found useful by all ornithologists, and particularly 

 those interested in field-work. It is in effect a key to the 

 species (which are not described in detail), and the genera 

 only come in as an aid to determining the species.
