With the exception of a very imperfect description, little was 
known relative to this interesting bird, anterior to Long’s expedi¬ 
tion to the Rocky Mountains. One of the notes annexed to the 
account of that journey contains an excellent description of this 
Swallow, with a notice of its habits, and remarkable manner of 
building. Mr. Dewitt Clinton has recently published a paper on 
the same subject, accompanied by some observations from Mr. 
Audubon. Combining what these gentlemen have made known 
with the information previously given by Vieillot and Say, we can 
present a tolerably complete history of the Cliff Swallow. 
Some doubts having been entertained whether the Hirundo 
lunifrons of the Rocky Mountains be the same species as the 
Hirundo fulva of the western part of New-York, I was desirous 
of deciding the question by comparing the specimens; this I ac¬ 
complished, through the politeness of Dr. Dekay of New-York, 
who, with the kindness and liberality distinctive of those who cul¬ 
tivate science for its own sake, sent me the specimen and nest 
deposited by Mr. Clinton in the cabinet of the Lyceum. Thus 
being possessed of the individuals in question, we are enabled to 
place their specific identity beyond the reach of future uncertainty. 
That Say considered his Hirundo lunifrons as a new bird, is
