Linneus=C. apricarius Linnzeus.) 
Rather large Charadriide (wing 147-189 mm.) resembling Squa- 
tarola but without trace of hallux, with bill much smaller and more 
slender, and upper parts spotted with yellow. 
Bill much shorter than head, slender, its depth at gonydeal angle 
equal to about one-fifth the length of culmen; culmen about as long as 
middle toe without claw or decidedly shorter, the distal portion 
decidedly convex; broad nasal fossa extending for more than basal 
half of maxilla; gonys nearly straight, with distinct though not 
prominent basal angle. Wing long and very pointed, the longest 
primary (outermost) exceeding distal secondaries by much more 
than half the length of folded wing and extending much beyond tips 
of longest tertials. Tail shorter than distance from bend of wing to 
tips of distal secondaries, truncated. Tarsus nearly one-fourth 
as long as- wing, slender, covered all round with small hexagonal 
scales, these larger in front; middle toe, without claw, decidedly 
more than half as long as tarsus, the lateral toes much shorter, the 
inner one decidedly shorter than the outer; hallux wanting; a small
