Genus XI. NICATOR. 
Type. 
Nicator, Hartl. and Finsch, Vog. Ost-Afr. p. 359 (1870). N. chloris. 
Bill rather long, slender, and compressed, with a straight culmen as 
far as the commencement of the hook; nostril semilunar, with a clearly- 
developed operculum, and partly, at any rate, exposed; rictal-bristles long 
and well developed ; wing rounded, the fourth and fifth primaries the longest, 
the first about two-thirds of the second; tail rounded, about the same length 
as the wing; two proximal phalanges of the third and fourth toes united into 
a common sheath. Sexes similar, plumage green and yellow, like Malaco- 
notus, with pale yellow tips to the coverts and secondaries. 
This genus, containing three species, is confined to tropical and south 
Africa. The curious character of the toes is quite unique in the family.
