74 ZOOLOGY OF THE VOYAGE OF THE BEAGLE. 



Chiloe, where it is much less common than the Cheucau, it is called by the inha- 

 bitants Cheuqui. Kittlitz procured specimens from Concepcion. He describes 

 the cry which it utters over and over again, in the same high tone, as very 

 singular, and more like that of a frog than of a bird.

This bird has a wider range than the species of the foregoing and closely 

 allied genus. It is common near Port Famine in Tierra del Fuego, and on the 

 west coast in the thickly wooded islets of the Chonos Archipelago. I was assured 

 by an intelligent collector that this bird is met with, though rarely, in central 

 Chile ; and Mr. Gould informs me, that he has received specimens from that 

 country. It has found its way over to the Falkland Islands, where, instead of in- 

 habiting forests, it frequents the coarse herbage and low bushes, which in most 

 parts conceal the peaty surface of that island. In general appearance the Scy- 

 talopus fuscus might at first be mistaken for a Troglodytes, but in habits it is 

 closely allied to the several species of Pteroptochos. In a skulking manner, with 

 its little tail erect, it hops about the most entangled parts of the forests of Tierra 

 del Fuego; but when near the outskirts, it every now and then pops out, and 

 then quickly back again. It utters many loud and strange cries: to obtain a good 

 view of it is not always easy, and still less so to make it fly. A specimen I pro- 

 cured at Chiloe had its upper mandible stronger and more arched, but differed 

 in no other respect.

This bird has a considerable range. I procured specimens of it near Rio de 

 Janeiro, on the banks of the Plata, throughout Patagonia, in Tierra del Fuego, 

 where it is one of the commonest birds, and likewise in Central Chile : its habits 

 resemble very closely those of the common Troglodytes of England. In the open 

 country near Bahia Blanca it lived amongst the thickets and coarse herbage in the 

 valleys ; in Tierra del Fuego, in the outskirts of the forest. Its chirp is harsh. 

 In Chile I saw one in October building its nest in a hole in a stone wall, in a 

 situation such as would have been chosen by our Troglodytes.
