On proceeding to the Dentirostral Tribe of the Perching 
Birds, and commencing with the family of Laniade which forms 
part of the typical group of that tribe, we find representatives 
of most of the greater subdivisions of the family amon g the 
Australian birds. One subdivision alone is wanting, the sub- - 
family of Tyrannina, Swains. That group, or at least the typi- 
cal species of it, appears confined to the New World. The pre- 
sent subfamily of Dicrurina seems, on the other hand, to belong 
exclusively to the Old World; and specimens of two of its 
most prominent groups, the genera Artamus and Dicrurus, are 
in our collection. There appears, however, some difference in 
the geographical distribution of these two forms: the species of 
Artamus being chiefly inhabitants of the islands in the Southern 
Ocean, while those of Dicrurus extend their habitats from the 
continents of Africa and India to the neighbouring islands.

The bills of this bird, and we believe of all the species of the 
present genus, are of a bluish or lead colour at their base, with 
a black aper. | This Species has hence attained the name of Blue-
