 (Type, Vitijlora leucopygia Brehm?) 



Small long-winged, long-legged, terrestrial and saxicoline Tiirdidse 

 with wing-tip longer than tarsus, outermost (tenth) primary shorter 

 than primary coverts, exposed culmen shorter than middle toe (with- 

 out claw), and with basal portion of tail, together with upper tail- 

 coverts, white. 



Bill small and slender, much shorter than head; exposed culmen 

 decidedly shorter than middle toe (without claw) but longer than 

 inner toe (without claw) , more or less concave immediately in front of 

 nasal fossae, the mesorhinal portion more or less strongly elevated 

 basally ; gonys straight or very faintly convex, rising oblic[uely toward 

 tip at a slightly divergent angle from lower edge of mandibular rami, 

 the latter much shorter than gonys; maxillary tomium faintly convex 

 basally, faintly concave subterminally, distinctly notched near end. 

 Nostril guttate, pointed anteriorly, overhung by broad membrane, 

 posteriorly nearly or quite in contact with feathering of frontal antise. 

 Rictal bristles distinct; no distinct decumbent post-nasal bristles; 

 latero-frontal feathers with distinct bristle-like tips, the more anterior 

 ones projecting forward and downward over nostril. Wing very long 

 and pointed (about three and a half to four times as long as tarsus), 

 the longest primaries exceeding secondaries by more than length of 

 tarsus; outermost (tenth) primary small, sometimes shorter, some- 

 times slightly longer than primary coverts; ninth primary sometimes 

 longest or equal to longest, sometimes shorter than sixth. Tail more 

 or less shorter than distance from bend of wing to end of secondaries, 

 about twice as long as tarsus to much more than twice as long, even 

 or more or less distinctly emarginate. Tarsus long and slender, not 

 more (usually much less) than half as long as tail, much less than one- 

 third as long as wing (sometimes only one-fourth as long), the acro- 

 tarsium booted except on lower portion; middle toe (without claw) 

 decidedly less to very slightly more than three-fifths as long as tarsus; 

 lateral toes unequal, the inner (without claw) reaching to sub termi- 

 nal articulation of middle toe, the outer slightly but decidedly beyond; 

 hallux slightly shorter than inner toe, its claw nearly as long as the 

 digit — all the claws normally curved, but slender and very acute;
