Hub. Veragua. 



Obs. D. striaticipiti, Lawr. (Ann. of N. Y. Lye), affinis, sed 

 capite punctato nee striato, dorsoque cinereo nee olivaceo facile di- 

 gnoscendus. 



This species, and probably D. striaticeps, Lawr., ought perhaps to 

 be referred to the genus Tha?nnophilus rather than to Dysithamnus, 

 the bill being stronger than in any member of the latter genus, and 

 even more abruptly booked than in most Thamnophili. The bill, 

 however, is not so high ; and in this respect, and in having weaker 

 legs and feet, the form more resembles Dysithamnus ; while, on the 

 other hand, the tail is more rounded. 



7. FORMICARIUS RUFIPECTUS, Sp. 1). (PI. VIII.) 



F. supra fusco-niger, uropygio obscure rufo, pileo etiam rufo tincto : 

 /oris et gutture nigris : pectore, crisso et ventre medio casta- 

 neo-rufs, hoc di/utiore ; corporis /ateribus fidiginosis : rostro 

 nigro, pedibus fuscis. 



Long, tota 7 poll., alae 3"4, caudse 2*25, tarsi 1*5, rostri a rictu 1*1. 



Affinis F. anali, D'Orb. et Lafr., sed pectore castaneo-rufo primo 

 visu distinguendus. 



The genus Formicarius seems well denned, and separable from the 

 allied forms by several trenchant characters. The plumage consists 

 of short, moderately firm feathers, giving the bird a compact appear- 

 ance, very different from that of Ph/ogopsis, all members of which 

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

 its affines. The region behind the eye is naked; in Ph/ogopsis the 

 entire circlet is bare. The supranasal feathers of Formicarius are 

 short and compact ; in Ph/ogopsis they are long and prominent. 

 The scutella of the tarsi of the former are distinct and divided, while 

 Ph/ogopsis 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 Ph/ogopsis, which is nearly round. The hind claw is longer 

 and less curved. The tail is shorter, stiffer, and less rounded. I 

 have compared these two genera more minutely, as several species have 

 been included under Formicarius which indubitably belong to Ph/o- 

 gopsis. This latter genus contains four (perhaps five) species, viz., 

 P. nigro-maculata (Lafr. & D'Orb.), Syn. Av. in Mag. de Zool.
