* Tliere can scarcely be a doubt that Gmelin's name has the priority of that 

 of Temtninck ; but, since this bird has been in undisturbed possession of the 

 latter for upwards of half a century, we may fairly ignore the former, on the 

 ground that Gmelin's description does not "clearly define" the species. Gmelin's 

 name does not deserve to stand, inasmuch as he obviously never saw the bird, 

 or he would scarcely have copied Cettis error in ascribing the rufous tint to 

 the head instead of to the flanks.
