120 BRITISH GUYANA BIRDS EGGS. 
Il. Tyrannus melancholicus Vieill. 
They make a nest, like a cup, of small sticks lined 
with grass and the leaves of the bamboo, on the outer 
branches of moderately high trees. 
They lay three eggs. 
The egg — 26 mm. by 20 mm. — is greenish white, with 
red-brown and light brown markings over its entire sur- 
face. The eggs in the same nest vary much as regards 
size, brightness of colour, and number of marks. 
They hatch from January to June. — One egg (N°. 24). 
12. Symallazis cinnamomea (Gm). 
Rootie. 
The nest is built of small sticks in the centre of low 
bushes, and it is many times the size of the bird. The 
shape of the nest is a long oval, and it rests horizontally 
in the tree, one of the ends being in the middle of the 
bush, while the other end reaches to almost its outer 
margin. The place of entrance is in the top of the outer- 
most end of this oval mass, and its direction is at first 
downwards and then straight inwards to the other end 
where the nest proper is. This passage is formed by an 
archway of small sticks placed on end and meeting above. 
Where the eggs rest there is usually a lump of clay hol- 
owed out and lined with grass. 
They lay four eggs. 
The egg — 19 mm. by 15 mm. — is white, with a slight 
blue tinge and has no marks. 
They hatch in May and June. — Three eggs (N°. 33). 
13. Dendrornis pardalota (Vieill.). 
Carpenter Bird. 
They lay their eggs in holes, made by the bird itself, 
in the rotten wood of trees, especially in the Oronoque- 
tree, Sandcocer-tree, Erythrina glauca, the rotten wood
