HLTJiROSCiiLUS, Baird. 



(jjj Bill longer than the head r r the tarsus, stout, much compressed. Commissure straight to near the tip, where it is gently 



decurved. The culmen is slightly concave tibout the middle. Nasal groove extending over th6 basal two-thirds of the bill. 

 Mouth moderately cleft ; gape extending neai-ly the length of the nostrils behind the base of culiueu. Legs short. Tarsus about 

 equal to middle toe, and about 2i times the length of exposed tibia; covered anteriorly by narrow transverse scutellae, laterally 

 and behind by hexagonal scales. Scales of tibia hexagonal. Outer and middle toe connected by a basal web as far as the first 

 joint of the latter ; a rudimentary web to the inner toe. Hind toe long ; one-third the tarsus. Tail half the wings. Plumage 

 perfectly uniform above, without spots or bands of any kind. 



This very remarkable sandpiper differs, in the hexagonal scutellation of the tibia and on the 

 posterior iace of the tarsus, from any other of the Tolaneae, und on this account should, with all 

 propriety, be made the type of a distinct group. The till is stronger than in any American 

 Senus, except Symphemia, differing mainly from this in the straightness of the bill and greater 

 amount of inflection of the edges. The na.sal groove extends further forward, and the upper 

 •jaw is a little more decurved at the end. The gape is a little more deeply cleft. The legs, 

 especially the tarsi, are much shorter ; the inner toe only slightly webbed. The claws are 

 short, stout, and unusually curved. The legs have a much roughened appearance.
