ROBIN FLYCATCHER. 
first joint of tlie latter ; claws slender, arched, 
acute ; hill blackish ; legs pale. Inhabits Pondi- 
chery, M. Lesclierault : labelled in the Museum, 
“ Gobe Mouche Azuron.?— Yaill." 
Total length, in a straight line, about 5g inches ; 
bill, from the front, T 4 5 ; wings, 2^ ; tail beyond,

It is necessary to add, that the name above quoted 
seems to us erroneous. 
That the analogy of this singular bird to the 
robin should be illustrated more fully, we shall 
subjoin the circles of the two groups in which 
they respectively occur. 
GENUS MUSCICAPA. 
My'iagra. 
Muscipeta. 
Cryptolopha. 
Hyliota. 
Muscicapa. 
GENERA OF SAXICOLINaE. 
Saxicola. 
Thamnobia. 
Gryllivora. 
Petroica. 
Erytbaca. 
Without at present entering into all the details of 
these tw r o circles, we would apply our preceding 
observations as strong proofs in support of our 
belief, not only in the analogy of Muscicapa and 
Erythaca, which here stand opposite to each other, 
but in the union of the Mmcicapidcs, the Sylviada', 
and the Ampelidw (the three aberrant divisions of 
the tribe Dmtirostres ) into a circular group of their 
own, quite independent of the other two, which, 
w'hen united to this, constitutes the whole tribe. 
In whatever view, therefore, we may take of the 
My’iagra macroptera , whether as a genuine Myia-
