The genus Ploceella differs from Ploceus in many important particulars. The bill is much shorter, being no longer than it is high ; the nape is furnished with a few short hairs, and the tail is much longer and more rounded. The plumage of the male in summer is largely yellow. The nest differs much from that of a Ploceus, being supported at the sides by reeds and not suspended from their tips ; it has no tubular entrance, and the exterior surface of the nest is of quite a different appearance, being rough and coarse instead of smooth. The eggs are of all colours and but seldom pure white.
Ploceella approximates more to the African Weaver-birds than does Ploceus. Only one species of this genus is known.
