PARIANAS. 
By a resemblance in their habits and manner 
of searching for food, we are naturally led from 
the Gold-crests to the next of Mr Swainson’s sub- 
families, the Parlance, or True Titmice. These 
will exhibit the typical form, aud although many 
genera are wanting to trace out the minute 
relations between them and the other Sylviadce, 
their general connection will, nevertheless, be at 
once perceived. In the British Fauna this sub- 
family contains only two genera, the one we are 
now describing, and the genus Accentor. The Pari 
or True Titmice exhibit considerable modifica- 
tions of form, which, by some, have been con- 
sidered sufficiently varied to constitute different 
sub-genera ; in all, we possess seven species, 
five of which are perfectly typical, and the devia- 
tions of the other two will be pointed out under 
their respective descriptions. In geographical 
distribution they are spread' extensively over the 
old world, frequenting mostly temperate climates, 
or those districts of a warm region where the 
same character is kept up by an alpine elevation. 
Their natural habitation is in wooded countries, 
some abounding in parts comparatively cultivated,
