Male in Winter. — The similarity of the Grey and 

 Golden Plovers is not less striking than that of the Golden 

 Plover and the exotic species named marmorata. The Grey 

 is considerably larger then the Golden, but has the same 

 proportions, is coloured in the same manner, and undergoes 

 the same seasonal changes. It has a stouter bill, however, 

 and is furnished with an insignificant hind toe. These 

 trifling differences some have held sufficient to constitute a 

 genus, which they have named Squatarola, while others, 

 overlooking the differently formed wing, have referred it to 

 the genus Vanellus. The body is ovate and moderately full ; 

 the head of ordinary size, roundish, somewhat compressed, 

 with the forehead rounded. The bill is almost as long as the 

 head, straight, compressed, rather stout ; the upper mandible 

 with the dorsal line straight and slightly declinate for more 

 than half its length, then convex, the ridge convex, the nasal 

 groove extending beyond the middle, the edges sharp and 

 direct, the tip narrow but obtuse ; the lower mandible with 

 the angle narrow, the outline of the crura slightly concave, 

 the dorsal line ascending and slightly convex, the edges 

 sharp and direct, involute toward the tip, which is rather 

 acute ; the gape-line straight. 



The mouth narrow ; the palate with a double row of 

 papillae anteriorly. The tongue is an inch in length, slender, 

 emarginate and papillate at the base, grooved above, tapering 

 to a thin horny point. The oesophagus is five inches and a 

 quarter in length, about half-an-inch in width ; the proven- 

 triculus eight-twelfths broad, its glandules oblong, forming a 

 belt eight-twelfths in breadth. The stomach is a strong 

 gizzard, of an irregular roundish form, an inch and a quarter 

 in breadth, with thick lateral muscles, large radiating ten-
