Not figured.
Very similar in form and general appearance to the preceding, but
smaller, and with all the colors paler; bill very short and weak; gape
large; wing long; first quill slightly longest; tail moderate,
emarginate; tarsus feathered in front somewhat below the point with
the tibia; throat white; entire upper plumage brownish-black, mottled,
and variegated, with very pale cinereous, which predominates on the
back, rump, and coverts of the wings; under-parts with transverse
narrow bands of dark brown and yellowish-white; quills brownish-black,
with a wide transverse band of white at the distance from their end of
about one-third their length, and also with some irregular spots and
pairs of spots of rufous in their basal halves. Female paler, and with
the white of the throat tinged with pale reddish fulvous.
Dimensions. Total length, about 8½ inches; wing, 7¼; tail, 4½ inches.
Hab. Texas (Mr. Clark, Capt. McCown); New Mexico, Central America.
Spec. in Mus. Acad., Philada., and Nat. Mus., Washington.
Obs. This species is nearly allied to the preceding, and also to
_Chordeiles brasilianus_, from both of which it differs in some
particulars of form, and also in having its colors much paler. In the
latter character it somewhat resembles the _C. acutipennis_ of South
America. We regard this bird provisionally under the name above given,
but the description as cited is too brief to be satisfactory. It is,
however, the only species known to us that can be referred to it.
This bird is abundant in Texas during the summer.
