Genus SAUROTHERA Vieillot. 



Saurothera"' Vieillot, Analyse, 1816, 28; Nouv. Diet. d'Hist. Nat., xxxii, 1819, 

 348. (Type, Coucou a longbecBuEon^Cuculus vetula'Limxseus.) 



Large, very long-tailed, semiterrestrial Cuculinae (length about 390- 

 530 mm.) with bill as long as or longer than head, relatively slender 

 and straight, with tip abruptly decurved; tarsus longer than middle 

 toe with claw; tail more than one and a half times as long as wing, 

 graduated for more than one-third (sometimes nearly half) its length; 

 upper parts, including tail, plain olive (primaries sometimes chestnut), 

 under parts tawny, ochraceous, or buffy posteriorly, whitish to light 

 buffy brownish anteriorly, the rectrices (except middle pair) broadly 

 tipped with white and with a subterminal band or area of black. 



Bill slightly to decidedly longer than head, relatively straight and 

 narrow, abruptly decurved terminally, compressed, its width at 

 anterior end of nostrils decidedly less than its depth at same point; 

 exposed culmen much longer than tarsus, broadly rounded, nearly 

 straight to near tip, where abruptly decurved; gonys slightly to 

 considerably longer than the relatively long mandibular rami, nearly 

 straight (the terminal portion, however, usually very slightly concave), 

 slightly prominent basally, broadly rounded; maxillary tomium 

 nearly straight for most of its length but decidedly decurved termi- 

 nally, the basal portion slightly deflected, sometimes faintly convex. 

 Nostril longitudinal (sometimes slightly oblique), elliptical, in lower 

 anterior end of nasal fossa. Wing moderate, much rounded, the 

 longest primaries exceeding distal secondaries by not more (usually 

 less) than length of hallux, with claw; fifth, fifth and sixth, sixth and 

 seventh, or fourth to seventh primaries longest, the eighth slightly 

 longer to decidedly shorter than distal secondaries, the tenth (outer- 

 most) decidedly more than half as long as the longest. Tail more 

 than one and a half times as long as wing, graduated for more than 

 one-third to nearly half its length, the rectrices relatively broad. 

 Tarsus longer than middle toe with claw, at least one-fourth as long 

 as wing (usually more), rather stout. 



Plumage and coloration. — Orbits mostly naked; eyelashes strongly 

 developed; no trace of antrorse bristles about base of bill, but 

 feathers of head in general with fine bristle-like tips, directed back- 



o aaijpog, lacertus, dijpoju), venor. (Vieillot.)
