BIRDS. 15 



Agrees 'with P. trivirgatus of Timor in its black upper tail-ooirerts, 

 which in the type specimens of P. gouldi are grey. 



In the ' Catalogue of Birds ' (vol. iv. p. 419) I united Grould'a 

 MoncCrcha alhiventris with Piezorhynchus gouldi, but I now believe 

 that I was wrong in doing so. It may be a matter of opinion 

 whether the three forms here alluded to are more than local races or 

 ' subspecies ; but it is certain that the white-flanked individuals, P. 

 alhiventris (Gould), have the upper tail-coverts blackish, whereas in 

 the rufous-flanked birds, P. gouldi (Gray), the taU-coverts are grey. 

 Thus my " Key to the Species " {t. e. pp. 413, 414) will have to be 

 modified as follows :— 



cfi. Upper tail-coverts black. 

 «°. White ending to outer tail-feathers not 



exceeding an inch in length. 

 Ifi. -White ending to outer tail-feathers I'O- 

 12 inch, 

 a'. Four outer tail-feathers white at the 



ends ; black throat-stripe narrow . . trivirgatiis. 

 v. Three outer tail-feathers white at the , 

 ends ; black throat-stripe broad, 

 a'. Sides of body orange-rufous .... medius. 



h". Sides of body white alhiventris; 



v. Upper tail-coverts grey ; sides of body 



orange-rufous gouldi.

I am unable to follow Dr. Gadow in his conclusions respecting 

 P. melanura and its allies, P. die, P. macrorhyncha, and P. obiensis,' 

 all of which he unites together as a single species. Count Salvador! 

 has kept them distinct; and their specific characters I have endea- 

 voured to set forth in the following " Key ":—
