brownish shade; chin, throat, and cheek about the same shade of 

 <lark, brownish-grey as crown and neck. By cheek throughout 

 this paper is meant that strip oi leathers between the gape and 

 the lower extension of the lower mandible, and extending well 

 below the ear coverts and measuring about 18 mm. in length. 

 Upper tail coverts a paler shade than the back, but otherwise the 

 same colour. 



One s])ecimen, female, collected by writer near I'erth, al Bays- 

 water in August, 1901. 



One si)ecimen, male, from near Terlh, in v^..\. Museum, similar 

 to above. 



One specimen in National Collection, Melbourne, not tpiite 

 typical, probably a juvenile, from Guildford, near Perth. y\n- 

 other specimen in same collection labelled as from near Perth 

 (no locality) is the inland form, elelaiidi, Mat. 



(a) Northern Variant. — Two males were sent t(j me in the 

 flesh by Mr. C. E. Orton on 20th October last from Dandaraga, 

 about 100 miles north from Perth, and within 50 miles of 

 the coast. These birds are as large as the birds from near 

 Perth, but are washed throughout with a marked brownish tinge ; 

 the cheeks, chin and throat are paler than the crown and neck; 

 they are both evidently breeding, or I should have thought the 

 brown tinge was due to immaturity. 



Myzantha obscura clelandi, Mathews. 



Small bill ; diiTers from the dominant form in being generally 

 paler; cheek, chin and throat paler than crown and neck. 



Three specimens in the "H. L. White Collection" collected by 

 Mr. Tom Carter at Broome Hill, 200 miles S.E. of Perth, and 

 TTiarked obscura. 



Two specimens, both males, from the Stirling Range, the 

 nearest part of which is about 25 miles south of Broome Hill. 

 These were collected by Mr. Whitlock. 



Myzantha obscura ortoni, Ashby. 



Small bill; culmen 20 m.m. DiiTers from M.o. clelandi in 

 being generally paler, the brown tinge present in all the other 

 forms from W.A. being almost absent ; the cheek, chin, and 

 throat silvery grey. 



Four specimens in my own collection, two of which were taken 

 by myself from Moora, which is situated about 100 miles north 

 of Perth and the same distance from the coast. 



One specimen, a very large one, in the "H. L. W hite Collec- 

 tion," marked obscura. from Esperance Bay, about 250 miles fur- 

 ther to the east than any of the other localities referred to. But 

 for its large size this Esperance I'ay bird corresponds closely to 

 the birds from IMoora. 



Myzantha obscura melanotis, Wilson. 



Small bill; culmen 20 mm. DitYcrs from M. olKU-tira sensti 

 stricto and the two sub-species noted above, in that the black of
