5. Stelgidopteryx serripennis, (Audubon) Baird. I have found this 
Swallow on but one occasion, in May, 1872, when a single pair nested in 
this neighborhood, in a bank close to a stable, beside a pond. I watched 
this pair while they constructed their nest, during which time they were 
often seen to alight close together, on a board-fence from which they de- 
scended after the rough materials of which the nest was composed, — hay 
and feathers. Late in May I captured the female sitting upon four fresh 
eggs. I had no difficulty in doing this, for the hole was quite large, and 
not very deep, so that, by baring my arm, I could easily introduce it to 
the back of the hole. These eggs are pure white, and one of them meas- 
ures .80X.53 of an inch.

Stelgidopteryx serripennis. Rough-winged Swallow. — This spe- 
cies is a regular summer visitor, arriving about the last week in April, 
and though no't uncommon in the spring, but few remain to breed. By 
the first week in August, however, the species again appears, apparently 
on its southern migration, and becomes much more abundant than in the 
spring. On August 5, last, I noticed numbers of these birds in flocks 
of from ten to thirty individuals lining the fdnces along the roadside and 
outnumbering any of the other species with which they were associating. 
After September 9 none were observed. The greater abundance of 
this species in spring and late summer than in the intermediate season 
would seem to indicate a more northern range, and this, taken in connec- 
tion with the proximity to the Connecticut State line, and the fact that the 
course of migration at this point tends towards the northeast, would ap- 
pear to render their regular occurrence there almost assured.
