As stated, this species is very similar above to castaneus ; tli« 

 black bars on the tail are rather more continuous. The under purls, 

 however, are white, except flanks and crissuin — not chestnut ; the 

 bars riuch more decided, and extending forward over the jugulum, 

 throat, and chin, instead of being unmarked. The resemblance to 

 T. niyricapillus, Sclater, from Ecuador, is still closer ; this, how- 

 ever, has the throat pure white, instead of being barred with black.

General characters of Thryo'horus. The bill, in typical species, 

 much thicker and stouter, as in Cyphorinus ; height about one-tliird 

 length above ; culraen nearly straight to the rather abrupt extremity. 

 Owing to the greater breadth of the nasal membrane, the overhang- 

 ing roof of the nostrils becomes more valvular ; and, in the drieJ 

 specimen at least, is very apt to close the nostril, or to leave a very 

 narrow crescentic slit, thus distinguishing the genua very readily 

 from Thryophilus. The tail appears more graduated, and exhibits 

 a tendency towards being slightly decurved or arched above and not 

 plane. 



I have taken the characters above given partly from P. melanos, 

 the type, and partly from P. fasciato-ventris. The transition, how- 

 ever, from Thryothorus to Pheugopedius is quite gradual, through 

 such species as rutilus and macxilipectus. 2\ felix is more like 

 a Thryothorus in the bill, and nearest Pheugopedius in the tail. A 

 synopsis of the principal species will be found under Thryothorus.
