Of the four genera included in this tribe, three are 
common in England, but the fourth, that of the 
Pipras or Manakins, is entirely foreign, comprising 
a number of little birds of beautiful plumage. Some 
of these species are exceptions to the general rule 
of classification, as the upper mandible, on exami- 
nation, will be found, as in the Manakins, notched ; 
in other respects, the beak has a tolerably marked 
character, being short and usually feeble and flexible ; 
and, as the word subulirostrum implies, awl-shaped, 
from a Latin word, subula , signifying an awl, and 
rostrum a beak. 
Under the second genus, Varus , are comprehended 
the various species of Titmouse. Under the third, 
Motacilla , the Wagtails, Wrens, Robins, and a large 
family of singing-birds, usually separated from the 
rest under the term Sylvias, or Warblers ; at the head 
of which stands the Nightingale. Under the fourth, 
the Alaudce , or Larks. The Tomtits are familiar
