FAMILY CXLV. SCOLOPACIDJE- (THE SNIPE.) 

 Bill elongated, usually longer than the head ; if short, not plover- 

 like, being soft-skinned throughout (hard when dry) ; nasal grooves 

 in the form of narrow channels ranging from half to nearly the 

 whole length of the bill ; sides of lower mandible usually also 

 grooved ; nostrils narrow exposed slits ; head feathered. Wings 

 usually thin and pointed; tail short and soft; tibia rarely entirely 

 feathered. Tarsus never entirely reticulate and usually scutellate 

 in front and behind ; hind toe present (except in Calidris} ; front 

 toes cleft or slightly webbed; size medium or small. Sexes alike 

 or female slightly larger ; seasonal changes in plumage often 

 strongly marked. Eggs usually four, placed with the small ends 

 together in a slight nest or depression in the ground ; notes vari-
