246 Mr. J. H. Gurnets List of a Collection of Birds 
insects ; darts from a bough on its prey. Builds in holes in the 
banks, merely forming a small round chamber at the end of the 
hole. 
36. Ispidina picta (Bodd.). Painted Kingfisher. 
These birds feed entirely on butterflies and insects caught on 
the wing ; they frequent the dense bush, and are often seen along 
the streams, but never catch fish, 
37. Oxylophus serratus (Sparrm.). Edolio Cuckoo. 
Eye nearly black; tarsi slate-coloured. These birds feed on 
caterpillars, ants, and other insects, in search of which they 
hop about amongst the thick creepers, principally frequenting 
small, low, isolated bushes. They are weak on the wing, and 
do not take long flights, but are migratory, arriving in October 
and leaving in March. The gizzard of this bird is most curious : 
the inner skin is lined with hair like the hair of a young mouse, 
and is quite separate from the flesh of the gizzard. 
[It will be recollected that a similar appearance of the stomach 
being lined with hair frequently occurs in specimens of Cuculus 
canorus, and that these hairs were ascertained by the late Mr. 
Thompson of Belfast to be those of the larvse of the Tiger Moth, 
on which the Cuckoo frequently feeds. (See Proceedings of 
the Zoological Society for 1834, page 29.)—J. H. G.] 
38. Cuculus nigricans, Sw. African Black Cuckoo. 
Eye very dark brown. This bird has a very loud, harsh 
note, and is more shy than the generality of Cuckoos; it is 
active, remaining but a short time in the same spot; it feeds on 
caterpillars; it visits this part of the country periodically, dis¬ 
appearing during the winter months. 
39. Cuculus gularis (Steph.). African Grey Cuckoo. 
Eye brownish yellow; legs light yellow: very rare. Fre¬ 
quents small bushes in the open country; perches upright on a 
bough, like a Hawk, and resembles the smaller Hawks in its 
flight. 
40. Chrysococcyx smaragdineus (Sw.). Emerald Cuckoo. 
These splendid birds, though not by any means plentiful, 
are easily obtained, in consequence of their loud call, which they
