Bill slender, rather curved, with the culmen curved from the base to the tip, which is acute and entire ; 
^ le lateral margins curved and inflexed, and the gonys moderate and straight ; the nostrils basal, 
ateral, and sunk in a membranous groove, with the opening small and rounded. Wings short and 
r °nnded, with the fourth and fifth quills the longest. Tail long, broad, and even. Tarsi slender, 
milc ^ longer than the middle toe, and covered anteriorly with an entire scale. Toes short, the outer

°f tl * S ^ ^ 1G sout '^ cm P or ti ons of Africa, ancl the continent of India, that the species of this genus are found. Some 
e s P e cies are usually noticed in the bushes and woods, or on stony hills, but others are mostly observed about 
v a ° es ’ 011 high and old buildings, solitary, or in pairs, perched on the roofs, bushes, and trees, or examining the 
as ’ bouses, and even the ground, on which they exhibit great activity, frequently pursuing and capturing insects. 
pj e \ e engaged, they have the habit of jerking then’ tails up and down over their backs. They possess a series of 
Unq no * es w lii°h they pour forth while perched on the top of a wall or low tree. The nest is made on the ground, 
1 a thick bush ; the female usually deposits four eggs.
