The birds of the group just described which are in our collec- 

 tion are in general in bad condition, and we have been obliged 

 to confine ourselves to a few details only of their characters. 

 Even still we are not satisfied with our distinouishinc: marks. 

 The last species in particular is very doubtful, and we are not 

 quite certain that it even belongs to this genus. 



Genus. Dasyornis*. 



Rostrum forte, subarcuatum, culmine carinato, mandibulù supe- 

 riori vix emarginatâ ; nuribus basalibus, ovalibus, longitudi- 

 nalibus, membranâ supra partim tectis. 



Alee breves, rotunda? : remige prima subbrevi, secunda tertiâ et 

 quartâ gradatim longioribus, quintâ sextâ et septimâ ferè 

 œqualibus longissimis, caîteris gradatim decrcscentibus. 



Cauda elongata, gradata. 



Pedes subfortes, médiocres ; halluce forti, ungue subelonoato 

 arcuato ; acrotarsiis scutellatis, paratarsiis integris. 



Regio anteocularis vibrissis recumbentibus fortibus instructa. 



Corporis plumarum pogonia decomposita. 



This genus bears a very close resemblance to the group of 

 Timalia of the Javanese ornithology. In the shortness and 

 roundness of the wings, in the length and graduation of the tail, 

 in the carinated bill, and in the loose and decomposed feathers 

 of the body, it comes so close to that group that we should at 

 once refer our species to it, were it not for the singular bristles 

 that spring from the front of the forehead above the bill, and form
