CAPITONIDAE 45 I 



the rump being yellow ; the upper tail-coverts scarlet ; the fore- 

 head, sides of the head and lower parts yellow, with a tinge of scarlet 

 on the throat, which is followed by a black and white gorget. 

 The fine occipital crest is black, the beak green ; the feet and 

 orbits are dusky. T. margaritatus, of North-East Africa, has 

 brown upper parts with round white spots ; the upper and lower 

 tail-coverts are crimson ; the rump, head, neck, and 'under surface 

 are yellow, except for the crown and marks on the hind-neck and 

 throat, which are black, and for an indistinct chest-band of red, 

 surmounted by one of brown. The bealc is red, the feet are bluish. 

 The exclusively Central and South American Capita is the only 

 genus in which the sexes differ ; the dozen or more species have, 

 moreover, few bristles round the bill. C. niger of Guiana is 

 black above, varied with yellowish and buff, and sulphur-yellow 

 below with a few black spots, which become plentiful in the 

 female. The forehead, cheeks, and throat are orange-scarlet, the 

 bill is plumbeous. G. salvini of Costa Eica and Panama Has 

 green upper and yellow under parts ; most of the head and the 

 throat being scarlet, the flanks green and white, and a whitish 

 band descending the sides of the neck. The female lacks 

 the scarlet, but has a dull golden crown and nape, pale blue 

 cheeks, and an orange gorget below the green throat. The 

 bill is greenish-yellow, the orbits are yellowish. Tetragonops 

 rhamphastinus of Ecuador, in which the nostrils lie in grooves, has 

 the crown black, with white sides merging gradually into a blue- 

 grey throat ; a glossy black nuchal crest ; a rufous-olive mantle ; 

 orange lower back and upper tail-coverts ; blackish-blue wings 

 and tail ; scarlet breast with orange sides ; and yellowish-green 

 abdomen. The bill is orange - yellow with dusky tip. T. 

 frantzii of Costa Eica, called " Gallinita " from its chicken-like 

 cry, has greenish-olive upper and yellowish-green lower parts, 

 with golden-orange forehead, cheeks and throat, a plumbeous bill, 

 and a similar crest to its congener. This genus bears a certain 

 resemblance to the Toucans. 



Sub-fam. 2. Indicatorinae. — The Honey-guides are contained 

 in the two genera Indicator and Prodotiscus, with nine and two 

 species respectively, which were formerly placed among the Cuckoos. 

 Their chief interest centres in the fact that they are said to 

 conduct travellers to bees' nests, as will be seen below. 



From the Capitoninae, Indicator differs in the stout Einch-
