This species is of the group of Merula Javanica, but is especiallj^ 

 remarkable for the size of its bill, which is very large in proportion 

 to the bird. The sexes arc alike in colour, and the j'oung birds 

 are more dusky brown, with paht shaft-lines to the feathers of the 

 npper surface. In the young the bill is horn brown, not yellow, 

 and the under surface of the body is mottled with duskj--brown 

 edges to the feathers. 



[The Ground-Thrush is common everywhere, but is most numerous 

 near the coast. Like the other birds of the island, it is veiy tame, 

 and when I was breaking up rotten wood searching for beetles, 

 several of them would stand quite close by in readiness to pick 

 up any grubs that were uncovered. Its food consists of insects, 

 seeds, and any carrion it can find, and I have seen one kill a suuiU 

 brown lizard, though it seemed to have some difficulty in doing so. 

 When hunting for insects among the dead leaves, the colours of the 

 plumage harmonize so exactly with the surroundings that, were 

 it not for the bright yellow beak and eye-lids the bird would be 

 almost invisible. The alarm cry is much like that of the European 

 Blackbird, and in the pairing season (Deccmber-Januaiy) the male 

 has a song something like that of the English Thrush, but harsher 

 and less varied. The nest is made of fibres of the wild sago-palm 

 {Arenga listen'), skeleton leaves, and other vegetable fibre; it is 

 not mud -lined. One nest was taken from the crown of a screw- 

 pine {Pandatius), another from the hollow top of a broken tree 

 trunk, some fifteen feet from the ground. Eggs were found in 

 December, and in the following month young birds just able to 

 fly were numerous, and continued to be so till April. — C. W. A.]
