Genus PARUS Linn., 1766. / / © 
The genus Parus, of which the Great Tit of England may be 
considered the type, contains those Tits which are not crested 
and in which the tail is slightly rounded. ‘They have a broad, 
black, ventral band and in this character agree with Machlolophus, 
which, however, possesses a long pointed crest. 
The true Tits are found over a considerable portion of the 
world. Five species inhabit the Indian Empire, two being found 
over the greater part of Europe and Asia, i.e. major and palustris ; 
two, nuchalis and monticolus, being local; and the fifth, cyanus, a 
very rare visitor. 
In Parus the feathers of the crown are rather long, but do not 
form a crest; the tail is considerably shorter than the wing, and 
the outer feathers are shorter than the central ones by about the 
length of the hind claw.

The Great-Tits or Grey-Tits may be divided into two groups— 
the first group with green backs and yellow under parts, the 
second with grey backs and the under parts ranging from 
practically pure white to fawn or buff. ; 
The first group, that of the true Parus mujor, ranges over the 
whole of Europe, extrenie Northern Africa and Northern Asia to
