Birds of Paraguay. 519 



the National Collection from Brazil. I do not consider that 

 the bird described by Mr. Bertoni is separable from C. 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 l - 05 ; wing 34 ; 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.]
