This only differs from P. roseus in its larger size and longer bill, in having the frontal region much swollen, and in possessing 24 rectrices instead of 22. There is also apparently less difference in size and in the length of bill between the sexes.
Length of male about 72 ; tail 8 ; wing 28; tarsus 5.5; bill from gape 18. Females are smaller.
Distribution. Southern Europe, Northern Africa, and South¬western Asia. Some of the White Pelicans found in Northern India in the cold season belong apparently to this species, but the greater number are intermediate in size and other characters between P. onocrotalus and P. roseus.
* Some of these references probably belong to P. roseus, but as the two forms pass into each other in India, it is impossible to disentangle the synonymy.
