make at short intervals. They will remain on the same tree, 

 and nearly the same bough, for hours together j they feed prin- 

 cipally on caterpillars, but sometimes catch the winged females 

 of the white ant as they rise from the ground, darting upon 

 them similarly to the Flycatchers or Drongo Shrikes. It has a 

 swift dipping flight, similar to that of the Wagtails, and when 

 disturbed generally flies to a good distance. It frequents bushy 

 country near the coast. 



41. Chrysococcyx auratus (Gm,). The Didric Cuckoo. 

 [Sent from Natal, but not by Mr. Ayres.— J. H. G.] 



42. Chrysococcyx claasii (Cuv.). Klaas's Cuckoo. 



These birds are more active than C. smaragdineus, not re- 

 maining so long in the same place ; they also have the dipping 

 flight of the Wagtails, but do not call so frequently, and their 

 note is not so loud. They feed on caterpillars. 



43. Indicator minor, Stephens. Least Honey-Guide. 

 Too well known to need description. Feeds principally on 



caterpillars. 



44. Centropus superciliosus (Riipp.). Eyebrowed Spur- 

 Cuckoo. 



[Mr. Ayres has sent me two specimens, which appear both to 

 belong to this species. I add his remarks respecting each, pre- 

 mising that No. 1 appears to me to be an immature, and No. 2 

 an adult specimen. No. 1 is marked as $ by Mr. Ayres ; the sex 

 of No. 2 he has not marked. — J. H. G.] 



No. ] . Eye light brown ; legs bluish slate-colour. This 

 bird frequents the dense bush, and principally lives amongst 

 impenetrable creepers, where it hunts about in search of the 

 insects which it feeds upon ; if disturbed, it flies but a short 

 distance. 



No. 2. Eye splendid bright crimson ; bill black ; feet and legs 

 light slate-colour : is common here, and frequents marshy and 

 reedy places. I take it to be a distinct species from No. 1, the 

 colour of the eye differing so much ; but the note is precisely 

 similar — a loud, melancholy, cooing noise ; they call most in wet 

 weather ; they are fond of getting up into trees that are covered 

 with creeping plants, and sunning themselves; they generally
