IVeopisobia"- Mathews. Birds Y\astralia. iii, pt. 3, Aug. 18, 1913, 245, in text. 

 (Type, by original designation, Totanus damacensis Horsfield = Tringa sub- 

 ininuta Middendorff.) 



Medium-sized to very small Eroliiii?e (wing 82-146 mm.) with 

 completeh^ cleft anterior toes: tail two-fifths as long as wing, with 

 middle pair of rectrices projecting beyond the rest and more or less 

 contracted (sometimes siibacuminate) terminally, and exposed culrnen 

 not longer (usually shorter) than tarsus, the latter usually equal 

 to or even longer than middle toe with claw, but sometimes shorter. 



Bill straight, little if any longer than head (sometimes shorter), 

 the exposed culmen never longer (usually shorter) than tarsus, taper- 

 ing distally in lateral profile, its edges more nearly parallel in vertical 

 profile; nasal groove broad, at least basally, extending nearly to 

 base of the faintly decurved tip of maxilla; mandible with a nar- 

 rower and much less distinct lateral groove; nostril sub-basal, small, 

 linear; malar antia decidedly anterior to edge of loral feathering, the 

 mental antia still farther forward (about on same vertical line with 

 middle of nostril). Wing rather long, pointed, the longest primary 

 (outermost*) exceeding distal secondaries by half the length of wing 

 or slightly more, the acuminate or narrowed '^ longest tertials not 

 extending to tips of longest primaries. Tail more than two-fifths as 

 long as wing, nearly truncate but inclining to slightly rounded or 

 slightly emarginate (P. fuscicoUis and P. hairdi) , the middle pair of 

 rectrices contracted terminally (acuminate in P. maculata and 

 P. acuminata) and projecting, more or less, beyond the rest; rec- 

 trices 12. Tarsus not shorter (usually longer) than middle toe with 

 claw, except in P. mlnutilla and P. suhminuta (especially the latter), 

 usually a little less than one-fifth but sometimes (P. acuminata) 

 more than one-fourth as long as wing, continuously scutellate ante- 

 riorly and posteriorly; bare portion of tibia about as long as first 

 two phalanges of middle toe, or a little shorter, scutellate before 

 and behind; lateral toes decidedly shorter than middle toe, the 

 inner decidedly shorter than the outer; no trace of web in either 

 interdigital space. 



C'lloraiion. — In summer above brownish gray or grayish brown, 

 sometimes suffused or intermixed with rusty, spotted or broadl}- 

 striped with black; beneath wliite, except chest and forencck which 

 are pale buffy grayish or dull bufl'v more or less distinctly streaked 



^ Ntos, new -\- Pisobia. (Mathews.) 



^Sometimes (in /'. minuiilla and P. subminuta) the "second" primary is nearly if 

 not quite as long as the outermost. 



'"In the smaller species {P. minuiilla, P. subminuta, P. temviincki, P. vimiita, and 

 P. rujicollis) the elongated tertials are not acuminate, as in the larger species, but 

 have more or less l)roadly rounded tips, and are relatively longer, extending much 

 more nearly to tips of the longest primaries than in the larger species.
