Australian Birds in the Collection of the Linnean Society. 935 
deed, almost spurious. Of the foreign groups of the family we 
have already observed that the New Holland genera Malurus 
and Acanthiza come nearest the European type by the same 
construction of the wing. The present group essentially differs 
from it. The first quill-feather is long, almost equal to the 
second, which together with the third and fourth,—all of them 
nearly of a length,—are the longest. The nares also are linear 
and longitudinal, thus differing from the oval form of the Euro- 
pean type. In other respects the characters of these two groups 
have a general accordance. Besides the disposition of the 
wing-feathers, we may also mention the scutellation of the tarsi, 
the even tail, and the unarmed rictus, as additional marks of 
distinction from the before-mentioned New Holland Sylviade. 
From the genus Hylophilus of M. Temminck, which has lately 
been separated with much judgement from the Sylvia of Dr. La- 
tham, and which also has the first quill-feather elongated and 
nearly even with the rest, our present group may readily be dis- 
tinguished by a much more gracile and arcuated bill, in which 
the nares also are of a different construction. The Motacilla 
Maderaspatana of Linnæus, (Sylvia Madagascariensis, Lath.), 
belongs to our group, which seems to have a very wide dis- 
persion.
