on the eastern side of Australia some other examples, which 

 proved the existence of a second species, described by Mr. Ramsay 

 (op. cit. 1866, pp. 438-440) as A. rufescens; but still no suspicion 

 of the great divergence of the genus from the ordinary Passerine 

 type was raised, and it was generally regarded as belonging to the 

 Maluridze or Australian Warblers. However, the peculiar forma- 

 tion of the sternum in Atrichornis as the genus has to be called, 

 since Atrichia had long been preoccupied in zoology l attracted 

 the present writer's attention almost as soon as that of A. clamosa 

 was exhibited in the museum of the College of Surgeons, and at 



ATRICHORNIS CLAMOSA. (After Gould.) 



his request Mr. Ramsay a little later sent to the museum of the 

 University of Cambridge examples in spirit of A. rufescens, which 

 shewed a similar structure. The Scrub-birds were consequently 

 declared in 1875 (Encydop. Brit. ed. 9, iii. p. 741) to form a distinct 

 Family, Atrichiidse, standing, so far as was known, alone with the 

 LYRE-BIRDS as " abnormal Passeres." 2 Much the same view was also 

 taken by Garrod, who (Proc. Zool Soc. 1876, pp. 516, 518, pi. Hi. 



1 This fact seems to have been detected by Dr. Stejneger (Stand. Nat. Hist. 

 iv. pp. 459, 462). 



2 Mr. Sclater (Ibis, 1874, p. 191, note) remarked on the peculiar form of 

 sternum ; but, writing doubtless from memory, ascribed to it two emarginations 

 on each side of the posterior end, which it has not. The sternum is fairly 

 figured and briefly described by Eyton in 1874 (OsteoL Av. Suppl. ii. pi. 20,
