Birds of Paraguay . 
the National Collection from Brazil. I do not consider that 
the bird described by Mr. Bertoni is separable from G. cal - 
carata (Wied). 
[Like the preceding species this has the custom of feeding 
on the ground, the scratching of the dead undergrowth 
attracting one's attention. It is not so common as Conopo - 
phaga anomala, but specimens can usually be met with 
when looked for.— W. F]

Bill black above, slate-coloured below ; tarsi and feet 
bluish slate-coloured ; iris brown. 
Having compared these examples with a series of twenty- 
five of T. guttatus from Brazil, I find that the Paraguay bird 
has the fulvous on the lower abdomen and under tail-coverts 
paler and more restricted, giving the bird a whiter appear¬ 
ance, this is more especially marked in the male. Total 
length 8 inches ; culmen 1*05 ; wing 3*4 ; tail 4’8 ; tarsus 
1*2. I can only regard this form, however, as a subspecies 
of T. guttatus. 
[This species is fairly common throughout the country. 
A lazy slow-flying bird, it can be approached quite closely 
before flying away, and even then its flight is only for a 
short distance.— W. F]
