* In 1878 I pointed out that considerable obscurity existed as to the nama 

 of letccorhynckiis for this wide-spread species, but Lord Tweeddale argued very 

 ably for the retention of Linnaeus's name. Count Salvadori, however, in his 

 ' Ornitologia della Papuasia ' has adopted my conclusions, and as our no- 

 menclature has been widely followed, I propose not to resuscitate the name 

 given bv Linmeus, about which there must always be some reasonable doubt.
