include the Ant-birds which keep always on the ground, in contra- 

 distinction to those of the other subfamilies which live in the thickets 

 near the ground, but are generally Been on the branches. Whether 



the genus Pitta and its allied tonus of the Old World, which cer- 

 tainly show great outward resemblance to some of these birds, are to 

 be placed near here in a natural arrangement, does not \el seem 

 very certain. Cabanis in his ' Ornithologischc Xotizen,' leaves the 

 question in doubt, while Prince Bonaparte, who in his ■ Conspectus' 

 excluded the Pitta from the Tracheophones " geograpkia repug- 

 Hante," and placed them among the Oscines, in his more latch pub- 

 lished arrangement has located them near the Hollers {Coraciidce). 

 For this there seems to be some ground in the formation of the 

 skeleton, the thorax in Pitta having much of the same appearance as 

 in the Volatores. 



The series which I have arranged in this section is nearly the 

 same as that included by Prof. Burmeister in his division " Myio- 

 therida," with the exception of Sclerurus, which though somewhat 

 intermediate in form, seems to me to fall more naturally into the 

 Dendrocolaptidce or Anabatidm, where I assign to it the rank of a 

 distinct subfamily.
