 2.25. Nest in horizontal holes or burrows excavated in sand-banks, banks of 

 streams, etc. Eggs 3-6, .70 X -49, pure white. Hab. Northern hemisphere in gen- 

 eral; in America, south in winter to Cuba and Jamaica, and through Middle 

 America to Brazil 610. C. riparia (Linn.). Bank Swallow. 



Genus STELGIDOPTERYX Baird. (Page 458, pi. CXIV., fig. 5.)

 Adult: Above plain grayish brown, darker on wings and tail, the tertials usu- 

 ally margined with paler brownish gray ; beneath plain brownish gray, the bell}-, 

 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. Nest in holes, usually in banks (as in Clivicola riparia), 

 but often in abutments of bridges, etc. Eggs 3-6, .72 X -51, plain pure w^hite.

Genera. 

 a^. Wings pointed (first or second quill longest), decidedly longer than the short, 

 eveji tail ; primaries apparently only nine, the first being excessively minute, 

 nearly or quite concealed ; of those normally developed, the first or second

al 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 fossae; young not streaked 

 beneath. (Subfamily Ptilogonatince.^) 

 b^. Bill narrow, the Avidth 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;
