Resident. 
17. Ceyx tridactyla (Pall.). 1¢ 
A visitor; but not a migrant in the true sense.

much augmented in the winter months. 
24. Surniculus lugubris, subsp.? 26, 29 
It is difficult to decide whether these cuckoos should 
be referred to S. 1. dicruraoides Hodgs., the northern race

described from Pahang. In size they are intermediate, 
having a wing of from 131-136 mm.
