This is a very distinct species, at once known bj- its black under

Type. 

 Formicarius, Bodd. Tabl. d. PI, Enl. p. 43 (1783) F. eolraa f. 



The genus Formicarius seems "well defined, and separable from 

 the allied forms by several trenchant characters. The plumage 

 consists of short, moderately firm feathers, giving the bird a com- 

 pact appearance, very different from that of Phlogopsis, all members 

 of which genus have softer and longer feathers, more like those of 

 Pithi/s and its affines. The region behind the eye is naked ; in 

 Pldoijopsis the entire circlet is bare. The supranasal feathers of 

 Formicarius are short and compact ; in Phlogopsis they are long and 

 prominent. The scutella of the tarsi of the former are distinct and 

 divided, while Phlogopsis has a single shield on the front of the 

 tarsus. The nostril of Formicarius is oblong, and situated nearer 

 the base of the bill than that of Phlogopsis, which is nearly round. 

 The hind claw is longer and less curved. The tail is shorter, stifEer, 

 and less rounded (Saluin, P. Z. S. 1S(J6, p. 73). 



I am able to recognize seven species of Formicarius, which are 

 distributed over the Neotropical Region from Southern Mexico to 

 S.E. Brazil and Bolivia.
