PARIANS. 



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, and 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 Part 

 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,
