most singular sort of flycatcher, whose natural rela- 
tions, until the last week, had completely baffled 
us ; so much so, indeed, as to cast a doubt over 
our arrangement both of the Saxicolce and the 
Muscicapidce. The first impression, upon seeing 
this bird, is that of its being a robin ( 'Erythaica )„• 
k glance at its bill and its feet destroys this idea, 
and we should then pronounce it a flycatcher. But 
its tail is so totally unlike that of the restricted 
genus Muscicapa, where alone it might be supposed 
to enter, that we were altogether perplexed as to
