The plumage is coloured as in the last species, but this bird is rather larger and the naked skin of the head is very differently coloured. There is no red area on the crown, the occiput is smooth, the frontal area more rugose, the skin of the head is blackish brown, with a broad white ring tinged with blue at the nape just above the feathered neck.

Bill bluish ; irides orange-red : feet pale coral-red (Oates).

Length 30 ; tail 8 ; wing 16.5 ; tarsus 3.5; bill from gape 7.

Distribution. Pegu; Southern Tenasserim; Cochin China and Siam.

Habits, &c. This Ibis is a resident on the plains of the Irrawaddy, occurring singly or in pairs, with very similar habits to those of I. papillosus. In Southern Tenasserim it has only been observed at particular seasons. It haunts open plains or marshy fiats or the banks of rivers, and perches on high trees, and it has a harsh weird cry. Oates found on the 13th February a nest be¬longing to this bird, containing two pale blue eggs, one of which measured 2-55 by T8. The nest was of sticks on a tree.
