a. £ acl. Sapucay, November 30, 1902. 
Iris light warm brown. 
b, c. $ ; d, e. ? ad. Sapucay, April 25, 1904. 
Bill of a slate-colour at the tip, lighter at the base; cere 
and bare skin round the eyes yellowish ; feet buff, claws 
black ; iris brown. 
The two males have blue heads with a little patch of 
rufous on the occiput. One has the back almost devoid 
of black bars, whereas in the other, obtained on the 25th of 
April, there are numerous broad black bars. The hen birds, 
whether they have blue heads or a little rufous on the crown, 
are always distinguished by the brown streaks on the breast 
and sides of the body, whereas in the male these parts have 
black spots, very distinct on the sides. 
Four eggs were sent, collected on November 29, 1902. 
Three of these have a w^hitish ground-colour: one has 
minute chestnut-coloured spots evenly distributed over the 
entire surface, except at the larger end, where there are 
scarcely any at all; the second is similar, but has large 
blotches of chestnut-colour at the larger end ; the third 
has a cluster of blotches of the same colour at the large end; 
while the fourth has a reddish ground-colour with large spots 
distributed over the entire surface of the egg. 
[Resident and common all through Paraguay, nesting 
invariably in holes of trees. Along the streams which flow 
through the open camps and in the southern province, it lives 
to a very great extent upon fish and small reptiles. I have 
only seen the birds singly, never in pairs, and the nesting- 
habits are unknown to me.— W. F.~\
