2.25. West in horizontal holes or burrows excavated in sand-banks, banks of 
streams, etc. Hggs 3-6,-.70 x 49, pure white. Hab. Northern hemisphere in gen-

Species. 
Adult: Above plain grayish brown, darker on wings and tail, the tertials usu- 
ally margined with paler brownish gray; beneath plain brownish gray, the belly, 
anal region, and lower tail-coverts white. Young: Much like adult, but wing- 
coverts broadly tipped and tertials broadly margined with cinnamon, the plumage 
in general more or less tinged or suffused with this color. Length 5.00-5.75, wing 
4.00-4.70, tail 2.05-2.35. Mest in holes, usually in banks (as in Clivicola riparia), 
but often in abutments of bridges, etc. Eggs 3-6, .72 x 51, plain pure white. 
Hab. United States (except extreme northern border, and New England except 
Connecticut), south, through Mexico, to Guatemala.

Genera. 
a’. Wings pointed (first or second quill longest), decidedly longer than the short, 
even tail; primaries apparently only nine, the first being excessively minute, 
nearly or quite concealed; of those normally developed, the first or second 
longest ; rictal bristles obsolete; frontal feathers filling completely the nasal 
fosse, and concealing the nostrils ; young with lower parts streaked. (Sub- 
family Ampeling)....ccccccecsccrecctesccereucececescsseeveceees Ampelis. (Page 464.) 
a. Wings much rounded, shorter than the rounded, emarginated or graduated 
tail; primaries obviously ten, the first always very evident; of the remain- 
der, the third to fifth (actually, fourth to sixth) longest; rictal bristles very 
distinct; frontal feathers not encroaching on nasal fosse; young not streaked 
beneath. (Subfamily Ptilogonatine.) 
b'. Bill narrow, the width of upper mandible at posterior extremity of nos- 
trils decidedly less than length from nostril to tip; crest springing from 
centre of crown composed of narrow, somewhat recurved, feathers; 
adult male glossy black, with white on inner webs of quills; adult fe- 
male dull brownish gray, with white edgings on wings.
