It may be a matter of opinionwhether the three forms here alluded to are more than local races orsubspecies ; but it is certain that the white-flanked individuals, P.albiventris ( Gould), have the upper tail-coverts blackish, whereas inthe rufous-flanked birds, P. gouldi (Gray), the tail-coverts are grey.Thus my " Key to the Species " (t. c. pp. 413, 414) will have to bemodified as follows :White endiug to outer tail-feathers notexceeding an inch in length.6".
