the end of the nasal furrow, which extends beyond the middle of the bill, then 
slightly raised, but bent downwards at the tip. Nostrils small and linear. 
Wings long, pointed, the first quill the longest; the inner secondaries 
reaching to the tip of the third primary. Tail broad, slightly rounded. Legs 
moderately long, slender, bare for a short distance above the tarsal joint ; 
tarsus reticulated. Toes three only, slightly webbed at the base (p. 537). 
CHARADRIUS, L227eus.—Bill shorter than the head, straight, rather slender, the 
upper mandible straight to the end of the nasal furrow, then slightly raised, 
and decurved to the pointed tip. Nostrils sub-basal and linear. Wings long 
and pointed, the first quill the longest ; inner secondaries much shorter than 
in EZudromdas and somewhat shorter than in 2gzalzt’s. Legs of moderate 
length, slender, bare for a short distance above the tarsal joint ; tarsus reticu- 
lated. Toes three only, all directed forwards, slightly webbed at the base 
(p- 547). 
Seguataroia, Leach.—Bill nearly as long as the head, rather strong, upper 
mandible straight to the end of the nasal groove, which is long and wide, 
then raised and decurved to the tip. Nostrils sub-basal, linear. Wings long, 
pointed, the first quill the longest. Legs moderate, slender ; lower part of 
the tibia naked, tarsus reticulated. Toes four in number; three directed

VANELLUS, Srisson.—Bill shorter than the head, straight, slightly gampressed 
the points of both mandibles horny and hard. Nasal groove wide, and 
reaching as far as the horny tip. Nostrils basal, linear, pierced in the 
membrane of the nasal groove. Wings large, tuberculated or spurred in 
front of the carpal joint ; the first and second quill-feathers shorter than the 
third and fourth, which are about equal, and the longest in the wing. Legs 
slender, with the lower part of the tibix naked; tarsi reticulated behind, 
scutellated in front ; the three anterior toes united at the base by a membrane ; 
hind toe short, articulated upon the tarsus (p. 553). 
SrrepsiLas, ///iger.— Bill as short as the head, strong, thick at the base, tapering 
gradually to the point, forming an elongated cone ; the upper mandible the 
longer, rather blunt at the end. Nostrils basal, lateral, linear, pervious, 
partly covered by a membrane. Wings long, pointed, the first quill-feather 
the longest. Three toes in front, united by a membrane at the base and 
furnished with narrow rudimentary interdigital membranes; a hind toe

Hematorus, ZLizneus.—Bill longer than the head, straight, strong, the point 
much compressed, forming a wedge; culmen of the anterior part slightly 
convex ; upper mandible with a broad lateralg roove on each side for half the 
length of the bill ; mandibles nearly equal in size and length, with the thin 
ends truncated. Nostrils basal, lateral, linear, pierced in the membrane of 
the mandibular groove. Legs of moderate length, naked for a short space 
above the tarsal joint; tarsi strong. Three toes only, all directed forward, 
united at their base by a membrane ; claws broad (p. 559). 
RECURVIROSTRA, L2z7eu5.—Bill very long, slender, weak, depressed for nearly 
its whole length, flexible, pointed, and curving upwards ; the upper mandible
