18 Mr. G. L. Bates — Field-Notes on the 



the culmen less ridged than old birds, which have a sharp 

 ridge reminding one of the incipient ridge in a small Hornbill. 

 NoWj supposing that these signs o£ youth^ seen in the bill, 

 hold good in G. calvus as well, there are five birds in the 

 large series of the British Museum, of the form without 

 tufts, that are young. As an additional proof that they are 

 young, they all have a few small scattered feathers on the 

 top of the head. 



Here we have birds both old and young ivith tufts, and 

 birds both old and young without tufts.

These little Barbets have several times been caught in holes 

 in dead stumps or limbs. No. 1883 Avas caught thus in a hole 

 in a small stump, only a few feet from the ground. The 

 stump was half decayed and full of termites. The cavity 

 excavated by the bird was 100 mm. in greatest depth and 

 55 mm. in greatest diameter, the largest part not being the 

 bottom but a little over halfway down. The diameter of 

 the round entrance-hole was 20 mm., just big enough to 

 admit the fore-finger. In the bottom was a little bed of 

 fine chips, on which lay two glossy white eggs, which were 

 very thin-shelled and fragile and got broken. But one was 

 measured before it got broken, and was 15 x ITS mm. in 

 size. 



Other females of this species were brought by boys, who 

 said that they caught them in their holes ; but no other eggs 

 came to luuul ; the eggs generally got broken before they 

 reached mc. In one case the boy reported finding three 

 eggs.

A specimen (1985) was caught in its hole, which was in a 

 small dead limb, 50 mm. in diameter. The hollow made by 

 the bird ran downward about 70 or 80 mm., and was almost 

 as large as the limb, leaving only a thin shell of wood 

 around it. There was nothing in the hole but the bird,
