position of the nostrils this is precisely the case. The wing is 
but slightly longer than that of the Cliff Swallow. Ihe tail is 
forked, and of intermediate length. The feet are intermediate, 
but most resemble those of the Cliff Swallow. Ihe colors of the 
iris, bill, and feet, were noted at the time of capture as indistinguish- 
able from those of its mate — a Barn Swallow. In coloration, 
the wings and tail are intermediate between those of the two 
species, which are brown in the Cliff Swallow and blue in the 
Barn Swallow. The forehead is ferruginous, as in the Barn 
Swallow ; but the sides of the head and neck, behind the eye, where 
blue in the Barn Swallow and ferruginous in the Cliff Swallow, 
are an intimate mixture of the two. On the back, the buffy-white 
edging of the feathers is apparent, but not so plainly indicated as 
in the Cliff Swallow (the whole upper surface, except the ferrugi- 
nous frontal band, is uniform steel-blue in the Barn Swallow). 
The rump and upper tail-coverts differ from those of either species, 
although the pattern is that of the Cliff Swallow ; the color instead 
of tawny-ochraceous is cream-buff, lightly and irregularly spotted 
with blue, the longest coverts being purplish brown. The under 
parts most closely resemble those of the Barn Swallow ; chin and 
throat hazel, darker than the Barn Swallow and lighter than the 
Cliff Swallow, from which latter it differs in having the hazel color 
more extended posteriorly, and in lacking the black pectoral spot. 
The whole underparts, including the under tail-coverts, are washed 
with ferruginous, but less strongly so than in the Barn Swallow. 
The under wing-coverts are intermediate. Two outer rectrices 
are spotted with grayish white on the inner webs, these being 
immaculate in the Cliff Swallow, spotted in the Barn Swallow.
