xxii SYSTEMATIC ARRANGEMENT OF THE GENERA OF BIRDS 



slightly compressed towards the end ; nostrils in the middle of the 

 bill, narrow, with the aperture in front, pervious ; toes three, united 

 by a membrane as far as the first joint ; wings as in the last. Page 239 



110. Cursorius (Courser). Bill shorter than the head, depressed at the 



base, slightly curved, pointed ; nostrils basal, oval, covered by 

 a little protuberance. Legs long, slender ; toes three, very short, 

 divided nearly to the base, inner toe half the length of the middle 

 one ; its claw serrated ; claws very short ; wings moderate ; first 

 primary nearly as long as the second, which is the longest in the 

 wing. Page 240 



111. CharAdrius (Plover). Bill shorter than the head, slender, straight, 



compressed, somewhat swollen towards the tip ; nasal channel 

 reaching from the base through two-thirds of the bill, covered by a 

 membrane ; nostrils basal, very narrow ; tarsi moderate, slender ; 

 toes three, the outer and middle connected by a short membrane ; 

 wings moderate ; first primary longest. Page 240 



112 SquatArola (Grey Plover). Bill shorter than the head, straight, 

 swollen and hard towards the tip ; nostrils basal, narrow, pierced 

 in the membrane of a long groove ; le^s slender ; outer and middle 

 toe connected by a short membrane, hind toe rudimentary, jointed 

 on the tarsus, not touching the ground ; wings long, pointed ; first 

 primary longest. Page 242 



113. Eudromias (Dotterel). Bill shorter than head, slender, compressed ; 



nasal channel reaching about half length of bill. Wings mode- 

 rate ; inner secondaries much longer than in Charadrius.

114. yEGiALiTis (Ringed and Kentish Plovers). Bill much shorter than 



head, slender, straight to end of nasal channel, which extends be- 

 yond middle of bill, then slightly raised, but decurved at tip ; wings 

 long, pointed. Page 245 



115. Vanellus (Lapwing). Wings large, quills broad and rounded, the 



fourth and fifth primaries longest. In other respects resembling 

 Squatarola. Page 247 



1 16. IDemAtopus (Oyster Catcher). Bill longer than the head, stout, straight, 



forming a wedge ; legs moderate, stout ; toes three, bordered by a 

 narrow membrane ; wings long ; first primary longest. Page 248 



117. Strepsilas (Turnstone). Bill short, thickest at the base and taper- 



ing ; nostrils basal, narrow, pervious ; legs moderate ; three front 

 toes connected at the base by a membrane, fourth rudimentary, 

 jointed on the tarsus, touching the ground with its tip. Page 250 



FAMILY SCOLOPACIDiE 

 (Snipes, etc.) 



Bill long and slender ; toes four, the hind one weak and elevated, very 

 rarely wanting. 



1 18. Recurvtrostra (Avocet). Bill very long, slender, weak, much curved 



upwards, pointed ; legs long, slender ; front toes connected as far 

 as the second joint; hind toe very smalL Page 252 



119. PhAlaropus (Phalarope). Bill as long as the head, slender, weak, 



depressed and blunt ; front toes connected as far as the first joint, 



and bordered by a lobed and slightly serrated membrane ; hind toe 



not bordered. Pa g e 2 S3
