BIRDS OF NORTH AND MIDDLE AMERICA 239 



dd. Rectrices 10-12, soft, narrow, with narrowly rounded tips, tlie tail only 

 one-third as long as wing, graduated, and hidden by coverLs; longer 

 primaries exceeding longest (proximal) secondaries by more than 

 length of tarsus, strongly bowed ; outermost primary as long as second 

 and third or else very little shorter, the second and third (from outside), 

 or first to third, longest; bill relatively much smaller and weaker, the 

 culmen narrow and somewhat rigid, especially the basal portion 

 (mesorhinium), which is very narrow, distinctly ridged, and extended 

 much farther between the laterofrontal antiae, its posterior and acute, 

 or cuneate; legs and feet much slenderer; size much smaller (wings not 

 more than 117 mm.) Coturnix (unsuccessfully introduced)" 



Genus DENDRORTYX Gould 



Dendrorty.r Gould, Monogr. Odontoph., pt. 1, 1844, pi. 20 and text; pt. iii, 18S0, 

 introd., p. 20. (Type by monotypy, Ortyx inacroura Jardine and Selby.) 



Very large, long-tailed Odontophoridae (wing about 150-165 mm., 

 the tail about two-thirds to quite as long) with outermost primary shorter 

 than tenth (from outside), the fourth to eighth (from outside), longest, 

 the tail graduated for half the length of tarsus to more than the tarsal 

 length, and either with a continuous row of large transverse scutella on 

 outer side of planta tarsi, or with the planta tarsi largely covered by small 

 hexagonal scales with a continuous series of rather small transverse 

 scutella on upper portion of outer side only (D. barhatus). 



Bill relatively large and stout, the chord of culmen (from extreme 

 base) equal to decidedly more than one- third to nearly one-half the length 

 of tarsus; depth of bill at base equal to much more than distance from 

 anterior end of nasal fossa to tip of maxilla, and equal to or greater than 

 width of bill at rictus ; culmen strongly convex, sometimes arched basally, 

 broadly rounded though more narrow basally ; gonys very broad, distinctly 

 to slightly convex, its basal angle prominent. Outermost primary shorter 

 than ninth or tenth (from outside), shorter than distal secondaries, the 

 fifth to eighth or fourth, fifth and sixth longest. Tail two-thirds to quite 

 as long as wing, graduated for from half length of tarsus to the length 

 of the tarsus, the rectrices (12) broad, with broadly rounded tips. Tarsus

One species, Coturnix coturnix (Linnaeus), was introduced in large numbers 

 in New England, eastern Canada, Ohio, and Virginia, but after migrating south in 

 the autumn the birds were never heard of again.
