ZOOLOGY OF THE VOYAGE OF THE BEAGLE. 
Chiloe, where it is mueh less common than the Cheucau, it is called by the inha- 
bitants Chenqui. 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.
