Interior of British North America. 
49. Harporhynchus rtjfus. 
The ‘Fauna Bor.-Am/ records a specimen of the Brown Thrush 
from Fort Carlton, besides my own (‘ Ibis/ vol. iv. p. 5). 
50. ClSTOTHORUS PALUSTRIS. 
The Long-billed Marsh Wren, besides being obtained by my¬ 
self near Fort Carlton (‘ Ibis/ vol. iv. p. 5), was procured by Mr. 
Drummond on the eastern declivity of the Bocky Mountains, in 
latitude 55°. The time of its arrival and departure in Pennsyl¬ 
vania, mentioned by Wilson, and a few differences in colouring 
from that given by the same author, led me to suppose at the 
time that my specimen might be of a more northern and, perhaps, 
western species. However, all the specimens here referred to have 
passed through the hands of Dr. Sclater, than whom I suppose 
there is not a better authority on American birds in this country. 
51. Troglodytes parkmanni. 
My specimen (‘ Ibis/ vol. iv. p. 5) has been referred to this 
species. May not also that mentioned in the f Fauna Bor.-Am. J as 
T. aedon , from the Bocky Mountains, in lat. 55° N., be the same? 
With respect to other Wrens, it is not unlikely that T. hye- 
malis may be found in the interior, though the ‘ Fauna Bor.- 
Am/ does not mention it beyond Lake Huron. The Bock Wren 
(Salpinctes obsoletus) has been obtained on the high central 
plains in American territory, as far north as Fort Union on 
the Upper Missouri; it may consequently be looked for on the 
British prairies. 
52. SlTTA CANADENSIS. 
Besides inhabiting the Saskatchawan (‘ Ibis/ vol. iv. p. 5), the 
Bed-bellied Nuthatch is identified from Bed Biver Settlement 
by a specimen in the Smithsonian Institution, from Mr. Donald 
Gunn. 
It is worthy of note that not one of the five foregoing birds 
has been collected by Mr. Boss in the Mackenzie Biver district. 
They probably do not go so far north. 
53. Parus septentrionalis. 
Four specimens collected by me (‘ Ibis/ vol. iv. p. 5), after 
careful comparison, were pronounced to be of this long-tailed
