incorporate, as usual, such species as have been already 

 described. I have also added, under the modern 

 genera, the descriptions of some newly described 

 species. 



The genus Tamjpus of Oppel is omitted in the 

 following account of this family, as I have been unable 

 to obtain its characters. In the present confused state 

 of the Insessorial birds, the omission is probably of 

 little consequence; especially as the name itself cannot 

 be retained, it having long been pre-occupied in En- 

 tomology. 



GENUS LXXXII— FORMICIVORA, Swainson. ANT- WREN. 



Beak moderate, subcylindric, 

 the gonix straight ; no 

 bristles. 



Rostrum mediocre subcylin- 



draceum, gonyde recta ; 



vibrissae nullae. 

 Alee breves rotundatee, re- 



mex quarta vel quinta lon- 



gissima. 

 Cauda ssepe gradata. 

 Tarsi mediocres, graciles ; 



squamis lateralibus fre- 



quentibus. 



Wings short, rounded, the 

 fourth or fifth quill long- 

 est. 



Tail often graduated. 



Tarsi moderate, slender, with 

 numerous lateral scales. 



Myothera pars. Temminck. 



The birds of this genus are all South American, 

 and, as their name implies, usually subsist upon ants, 

 thereby being of infinite service in ridding that part 

 of the world of those noxious pests.
