cephala) (1474), “Tinker-bird” (Barbatula pusilla) (1464), and “ Tron- 
smith” (Cyanops) (1471-1473). Fruits, buds, and insects form their 
principal food, but in captivity they will eat meat or small birds. 
From three to five oval white eggs are laid in a hole in a soft-wooded 
or dead tree excavated by the birds, who cut a neat circular entrance 
sunilar to that made by the Woodpeckers. More than a hundred 
species are recognised and are grouped into some twenty genera, nearly 
all of which are represented in the Case. 
Among the more striking we may draw attention to the tooth-billed 
forms such as Pogonorhynchus dubius (1456), with the base of the bill 
hidden by dense tufts of bristles, and its allies belonging to the genera 
Lybius (1457, 1458), and Tricholema (1459, 1460). In all the other 
genera the edge of the upper mandible is entire. An exception to 
the gaudy plumage and striking contrasts in colour is found in the 
West African forms Gymnobucco calvus (1461), with its curious bare 
head, and Heliobucco bonapartei (1462) ; also in Calorhamphus hayi (1466) 
from the Malay Peninsula; all three are birds of singularly plain 
appearance. One of the largest is the Great Himalayan Barbet (Mega- 
lema marshallorum) (1467), and the most brilliantly coloured members 
are found in the Oriental genus Cyanops (1471-14173) and the South 
American Capito (1480-1484), which are remarkable in having the 
plumage of the sexes different. 
Family II. Inpicatrorrpm. Honry-Guinss. 
[Case 65.] This small family of dull-coloured birds includes about a dozen 
species mainly confined to Africa; but two species occur in the 
Oriental region, one inhabiting the Himalaya, and the second the 
Malay Peninsula and Borneo. ‘The popular name is derived from the 
curious habit of certain African species, which lead men to bees’ nests 
for the sake of sharing the spoil. On observing a man the bird comes 
fluttering from branch to branch, uttering a shrill ery to attract 
attention, and, if followed, gradually leads him to a nest of bees, its 
object being to obtain the portions of the comb containing the grubs. 
The two Oriental species are not known to share this peculiar habit ; 
but, so far as is known, the food of all the Honey-Guides consists of 
Hymenoptera. The white eggs are deposited in a hole in the stem or 
branch of a tree, and the birds are said to utilise the old nest-hole of a 
Barbet or Woodpecker for the purpose. The species of Indicator, of 
which the Common Honey-Guide (1486) is a well-known example, have 
a stout, rather finch-like bill, while in Prodotiscus regulus (1488) and its 
allies it is more slender and pointed.
