 818, LESS. Ornith. PI. 100, fig. 2, NAUM. Taf. 216; the common curlew; 

 broods on the dunes in Holland, inland in England on elevated spots ; this 

 species occurs in Europe, Asia and North Africa. Another smaller, with 

 short bill, is also very common in Holland, less common than the last in 

 England; does not breed in Holland; Numenius phceopus LATH., Scolopax 

 pkceopus L., NAUM. Taf. 217. These birds are almost all similarly marked, 

 grey-brown above ; the tail is white with transverse black bars. The bill of 

 the young bird is much shorter ; a species occurs in North America of which 

 the bill is longer than that of the common curlew, Numenius longirostris

This is a numerous genus of which species occur in all the warm countries 

 of the world; they have great resemblance to the preceding genus, but, 

 on the other hand, form the transition to the storks and herons.
