 feathers directed forwards. Tongue capable of great protrusion, beset at the tip 

 with horny barbs. Wings moderate ; the first primary very short, the fourth 

 longest, but the fifth nearly equal to it. Tail of twelve graduated rectrices, the 

 outer pair very short and overlying the next, which with the rest are pointed

 in front above ; toes two before and two behind, the fourth, which is turned 

 backwards equal to the third ; claws strongly hooked, grooved and very sharp.
